    The sex industry, where men sell sexual services to other men or women, has grown in recent years. These men who offer sexual services are particularly vulnerable to HIV infection due to such factors as: frequency of risky sexual practices, number of sex partners, drug-taking, prevalence of sexually-transmitted infections (STI) and their specific situation of social exclusion which may hinder access to health services. These multi-faceted realities faced by sex workers explain the burgeoning interest in new avenues of scientific research. There are too few preventive programs however aimed at this population group and the studies that evaluate their effectiveness are fewer still. In this article we survey more recent studies on the difficulties of implementing programs for HIV prevention in male sex workers (MSW), as well as the studies that have gauged the impact of preventive programs in this group.

    The present study explores intimate partner violence (IPV) among female sex workers from the red-light area based in Mumbai, India. Using a grounded theory approach, in-depth interviews were conducted with ten sex workers to explore their experiences of IPV in the context of commercial sex work. Narratives were analyzed and themes constructed. A…

    Male sex workers who sell or exchange sex for money or goods encompass a very diverse population across and within countries worldwide. Information characterising their practices, contexts where they live, and their needs is limited, because these individuals are generally included as a subset of larger studies focused on gay men and other men who have sex with men (MSM) or even female sex workers. Male sex workers, irrespective of their sexual orientation, mostly offer sex to men and rarely identify as sex workers, using local or international terms instead. Growing evidence indicates a sustained or increasing burden of HIV among some male sex workers within the context of the slowing global HIV pandemic. Several synergistic facilitators could be potentiating HIV acquisition and transmission among male sex workers, including biological, behavioural, and structural determinants. Criminalisation and intersectional stigmas of same-sex practices, commercial sex, and HIV all augment risk for HIV and sexually transmitted infections among male sex workers and reduce the likelihood of these people accessing essential services. These contexts, taken together with complex sexual networks among male sex workers, define this group as a key population underserved by current HIV prevention, treatment, and care services. Dedicated efforts are needed to make those services available for the sake of both public health and human rights. Evidence-based and human rights-affirming services dedicated specifically to male sex workers are needed to improve health outcomes for these men and the people within their sexual networks.

    Full Text Available OBJECTIVE: To report on the sociodemographic characteristics and work experiences of 31 male sex workers (MSWs in the city of Córdoba, Argentina. METHODS: Information on each of the MSWs was collected using a questionnaire that covered his personal characteristics and his work background, self-assessed general health status, and use of health and social services. Scales were included in order to assess attitudes towards condom use, knowledge about safe sex, perceptions about the risk of getting HIV, individual self-efficacy, and locus of control. The questionnaire also asked each respondent to rank his level of agreement with interactive strategies for gaining client compliance with safe sex practices. RESULTS: In terms of their self-identity, out of the 30 MSWs who answered the question, 10 of them (33.3% self-identified as heterosexual and 9 (30% as bisexual. Alcohol and drug consumption and unsafe sexual practices were relatively low among the MSWs. Of the 31 MSWs responding, 21 of them (67.7% reported that they had been tested for HIV, but only 13 of them (41.9% said they had been vaccinated for either hepatitis A or hepatitis B. A variety of differences were found between the study's 17 street sex workers (sex workers who offer their services in public places such as streets and parks and the 14 independent sex workers (sex workers who are self-employed, advertise and manage their own business, and have an exclusive location for their commercial sex work. The street MSWs were younger and had less formal education. Independent MSWs were economically more settled, had been working longer in the sex industry, and were more comfortable about having sex with men. Independent MSWs were also more likely to report a gay sexual orientation and less likely to report using alcohol, marijuana, or other substances. CONCLUSIONS: The differences between street MSWs and independent MSWs are important since they could influence the negotiating of safer sex

    Although indoor male sex workers (MSWs) have been found to engage in lower rates of HIV risk behavior with clients than street-based MSWs, few studies have examined the motivations behind such practices. We interviewed 30 MSWs working for the same escort agency regarding their safer sex practices with clients and their reasons for these. As in other research, MSWs reported little risk behavior with clients. Five motivational themes related to safer sex on the job emerged: health concerns, emotional intimacy, client attractiveness, relationships, and structural work factors. Results suggest that participants engaged in rational decision-making relative to sex with clients, facilitated by reduced economic incentive for riskier behavior and a supportive social context. MSWs desired a safe sexual work place, personal integrity, and minimal negative consequences to personal relationships. Collaborating with sex work employers to study their role in encouraging a safer workplace may be important to future research.

    Tijuana, situated adjacent to San Diego, CA on the US-Mexico border, is experiencing an emerging HIV epidemic, with prevalence among female sex workers (FSWs) having risen in recent years from Tijuana. In 2008, males from San Diego (N = 189) and Tijuana (N = 211) aged 18 or older who had paid or traded for sex with a FSW in Tijuana during the past 4 months were recruited in Tijuana's red light district. Participants underwent psychosocial interviews, and were tested for HIV, syphilis (Treponema pallidum), gonorrhea (Neisseria gonorrhoeae), and Chlamydia (Chlamydia trachomatis). Of 394 men, median age was 36 years, 42.1% were married, and 39.3% were unemployed. Ethnic composition was 13.2% white, 79.4% Hispanic, and 7.4% black or other. Half (50.3%) reported unprotected vaginal or anal sex with FSWs in Tijuana in the past 4 months. High proportions reported using drugs during sex (66%), and 36% reported frequenting the same FSW. Factors independently associated with unprotected sex with FSWs were using drugs during sex, visiting the same FSW, being married, and being unemployed. FSWs' clients represent a sexually transmitted infections/HIV transmission "bridge" through unprotected sex with FSWs, wives, and other partners. Tailored interventions to promote consistent condom use are needed for clients, especially within the context of drug use and ongoing relations with particular FSWs.

    Full Text Available To investigate self-report of heterosexual anal intercourse among male sex workers who sell sex to men, and to identify the socio-demographic characteristics associated with practice of the behavior.Two cross-sectional surveys of male sex workers who sell sex to men in Mombasa, Kenya.Male sex workers selling sex to men were invited to participate in surveys undertaken in 2006 and 2008. A structured questionnaire administered by trained interviewers was used to collect information on socio-demographic characteristics, sexual behaviors, HIV and STI knowledge, and health service usage. Data were analyzed through descriptive and inferential statistics. Bivariate logistic regression, after controlling for year of survey, was used to identify socio-demographic characteristics associated with heterosexual anal intercourse.From a sample of 867 male sex workers, 297 men had sex with a woman during the previous 30 days - of whom 45% did so with a female client and 86% with a non-paying female partner. Within these groups, 66% and 43% of male sex workers had anal intercourse with a female client and non-paying partner respectively. Factors associated with reporting recent heterosexual anal intercourse in bivariate logistic regression after controlling for year of survey participation were being Muslim, ever or currently married, living with wife only, living with a female partner only, living with more than one sexual partner, self-identifying as basha/king/bisexual, having one's own children, and lower education.We found unexpectedly high levels of self-reported anal sex with women by male sex workers, including selling sex to female clients as well as with their own partners. Further investigation among women in Mombasa is needed to understand heterosexual anal sex practices, and how HIV programming may respond.

    Male sex work in the western countries has changed, including now a subculture of male sex workers who have paid sex with men arranged for via the internet. The men involved in this subculture do not easily identify themselves as sex workers nor as homosexual, and are therefore missed by regular health care and public health interventions. These male sex workers may form a hidden key population for sexually transmitted infections (STIs) and HIV, bridging towards other persons outside this context. This clinic-based observational study included consultations by male sex workers (n = 212), female sex workers (n = 801) and in men having sex with men who did not report being paid for sexual contacts (MSM, n = 2703) who received STI and HIV testing and counselling at our clinic during the study period. In this study we compare the consultations in male sex workers to those in in female sex workers and MSM. Demographic characteristics and sexual behaviour of the male sex workers, female sex workers and MSM were compared using chi-square tests and non-parametric tests. Using univariate and multivariate regression analyses, determinants for STI positivity in male sex workers were evaluated. Male sex workers tested positive for STI (including HIV) in 40 % of the consultations; female sex workers and MSM respectively in 9 and 14 % of the consultations. A new HIV infection was found in 8 % of the consultations of male sex workers. Male sex workers were a young population of migrant sex workers from Eastern Europe. They reported more often to also have sex contacts with women and other sex workers. Male sex workers are at a higher risk for one or more new STI than female sex workers and other MSM, even after correction for age, ethnicity, known HIV positivity and behavioural variables. Male sex workers form a hidden key population that impacts the transmission of STI and HIV within the MSM population and, possibly, to the heterosexual population. They require specific targeted

    We investigated prevalence and correlates of sexual risk behaviours among male and female sex workers in Tijuana, Mexico, the busiest border crossing area on the US - Mexico border, analysing survey data from a purposive, cross-sectional sample of male and female sex workers who worked in a range of indoor and outdoor settings. Logistic regression was used to determine factors that were associated with sexual risk-taking, defined as failing to use a condom with last client. In bivariate regression models, gender, work setting (e.g., indoor vs. outdoor), poverty, engaging in survival sex, marital status and perceived drug addiction were correlated with sexual risk. When controlling for work location, housing insecurity, poverty, survival sex, marital status and perceived drug addiction, male sex workers were still 10 times more likely than female sex workers (FSW) to engage in sex without a condom during their last encounter with a client. And, although FSW were significantly more likely than males to have used a condom with a client, they were significantly less likely than males to have used a condom with their regular partner. Future research should further examine how gender shapes sexual risk activities in both commercial and non-commercial relationships.

    The molecular epidemiology data of torque teno virus (TTV) in Indonesia is very rare. This study evaluated the prevalence of TTV in male commercial sex workers, as one of the high risk community for blood borne viruses pathogens in Surakarta, Indonesia. All blood samples collected from male commercial sex workers in Surakarta in 2009-2013 were tested by nested polymerase chain reaction (PCR). The amplified PCR products were molecularly cloned and subjected to sequence analysis. TTV DNA was detected in 80.9% (72/89) samples. Furthermore, the molecular characterization revealed that the most prevalent was genogroup 3, followed by genogroup 2 and l, respectively. TTV was detected in male commercial sex workers in Surakarta with high infection rate. Further investigation about TTV circulation in Indonesian population is needed in order to provide additional information about the genetic variability and TTV epidemiology in Indonesia, especially in the high risk communities.

    This study examined correlates of unprotected vaginal and anal sex (UVA) with male clients among female sex workers (FSWs). Baseline data were gathered from 1089 FSWs recruited from 13 cities across Mexico enrolled in an evidence-based sexual risk reduction intervention. We used generalised estimating equations (GEE) to predict total UVA while controlling for the nested structure of the data. Total UVA with clients in the past month was examined in relation to selected sociodemographic, substance-use, and micro- and macro-environmental factors. A greater number of UVA acts was associated with three micro-level environmental factors (i.e. never getting condoms for free, unaffordability of condoms, greater number of clients per month), and three macro-level environmental factors (i.e. lower health and higher education indices, greater population size of city). These findings suggest the development of social and structural approaches to HIV prevention for FSWs in Mexico, including modification of venue-based policies that pressure FSWs to maximise client volume, changes to the work environment that promote availability and affordability of condoms, and improved population health. Moreover, our findings call for the development of context-specific HIV interventions that take into account variations in the sexual risk behaviours and HIV risk environments of FSWs throughout Mexico.

    Mexico has a concentrated HIV epidemic, with male sex workers constituting a key affected population. We estimated annual HIV cumulative incidence among male sex workers' partners, and then compared incidence under three hypothetical intervention scenarios: improving condom use; and scaling up HIV treatment as prevention, considering current viral suppression rates (CVS, 60.7 %) or full viral suppression among those treated (FVS, 100 %). Clinical and behavioral data to inform model parameterization were derived from a sample (n = 79) of male sex workers recruited from street locations and Clínica Condesa, an HIV clinic in Mexico City. We estimated annual HIV incidence among male sex workers' partners to be 8.0 % (95 % CI: 7.3-8.7). Simulation models demonstrated that increasing condom use by 10 %, and scaling up HIV treatment initiation by 50 % (from baseline values) would decrease the male sex workers-attributable annual incidence to 5.2, 4.4 % (CVS) and 3.2 % (FVS), respectively. Scaling up the number of male sex workers on ART and implementing interventions to ensure adherence is urgently required to decrease HIV incidence among male sex workers' partners in Mexico City.

    HIV prevention efforts must be comprehensive in their understanding of the factors involved in HIV risk. Male clients, who have received less research attention than female sex workers (FSWs), may experience stigma as a function of purchasing sex. Perceived stigma may be related to poor psychological outcomes, risky psychosexual characteristics, and higher drug and sexual risk behavior among male clients of FSWs. However, perceived stigma of purchasing sex may differ between clients of different ethnic groups. In the present study, we examine the correlates of perceived stigma of purchasing sex among Latino versus non-Latino male clients of FSWs in Tijuana, Mexico. Using time-location sampling, we recruited 375 male clients (323 Latino, 52 non-Latino) in Tijuana who completed a computerized survey on various measures. We measured perceived stigma of purchasing sex using three items we developed for this study. Using linear regression analyses we found that perceived stigma was associated with greater guilt, a greater feeling of escape from everyday life, and more negative condom attitudes among Latino clients. This was not found among non-Latino clients. Features of Latino culture, like machismo, and how they may relate to stigma of purchasing sex are discussed.

    Male sex workers are a highly marginalised group in Hong Kong and it is increasingly so with an influx of them travelling from mainland China to work as "freelance" sex workers. This study aimed to measure important work environment variables that might affect the likelihood of condom use among male sex workers working in Hong Kong. A cross-sectional survey of 161 participants recruited by snowball and convenience sampling methods through outreach workers of a local non-governmental organization was conducted in 2007-2008. Only 27.4%, 54.7% and 42.6% reported consistent condom use when engaging in oral, anal and vaginal sex, respectively. Logistic regression shows unsafe sex was nearly four times (OR=3.41; 95%CI 1.51-7.69) as common in institutionalised male sex workers as among their independent counterparts. Lack of condoms provided at workplaces was a major barrier in this socio-legal context and was strongly associated with condom non-use amongst institutionalised sex workers (OR= 10.86; 95%CI 2.94-40.17). The present study finds that when compared with independent Male sex workers (MSWs), institutionalised MSWs were older, less educated, earned a higher income but more likely to engage in unsafe sex with their clients and their partners. Public health physicians must work with law-enforcing authorities to provide clear guidelines to remove these HIV prevention barriers.

    Most studies of heterosexual sex risk practices have focused on condomless vaginal sex despite evidence that condomless anal sex has a significantly higher risk of HIV transmission. The present study focused on male clients' anal sex practices with female sex workers (FSWs) in Tijuana, Mexico, where an HIV epidemic is growing among high-risk groups. Logistic regression analyses were used to identify psychosocial and behavioral correlates of anal sex among male clients. Our sample of HIV-negative men (N = 400) was predominantly Latino (87.5 %), born in Mexico (78.8 %), never married (36.8 %) or in a regular or common-law marriage (31.5 %), and employed (62.8 %), with an average age and education of 37.8 and 9.2 years, respectively. Eighty-nine percent identified as heterosexual and 11 % as bisexual. By design, 50 % of the sample resided in Tijuana and the other 50 % in San Diego County. Nearly half (49 %) reported at least one incident of anal sex with a FSW in Tijuana in the past 4 months; of those participants, 85 % reported that one or more of their anal sex acts with FSWs had been without a condom. In a multivariate model, anal sex with a FSW in the past 4 months was associated with bisexual identification, methamphetamine use with FSWs, repeat visits to the same FSW, higher scores on perceived stigma about being a client of FSWs, and sexual compulsivity. Prevention programs are needed that address the behavioral and psychosocial correlates of heterosexual anal sex in order to reduce HIV/STI transmission risk among male clients, FSWs, and their sexual network members.

    Recent research has provided increased information about the clients of sex workers; however, little is known about the population of older male customers who contract for heterosexual services online. Clients (N = 208) between 60 and 84 years of age were obtained through sex work review sites and online discussion forums. Participants completed a 129-item questionnaire focusing on physical health, sexual and non-sexual behaviors with sex providers, and the qualities sought in the same. More than half reported having visited sex providers between 13 and 24 times or more during the past 12 months. Participants' advancing age was positively associated with frequency of paid sex. Most frequent sexual activities with providers were fellatio without a condom, followed by penile-vaginal sex with a condom. Analyses also examine the relationship between aging and buying sex. Those with higher incomes and without spouses or partners were more likely to report non-sexual activities with providers, and many participants sought a "GFE" or girlfriend experience, in which paid sexual exchanges are part of a relationship that mirrors conventional non-remunerative relationships.

    Male sex workers (MSW) are a significant but invisible population in India who are at risk for HIV/sexually transmitted infections (STIs). Few studies from India have documented HIV risk factors and motivations for sex work in this population. Between 2013 and 2014, a community-based convenience sample of 100 MSW in Chennai (south India) completed a baseline risk assessment as part of a behavioral intervention. Participants were ≥18 years, and reported current sex work. We report medians and proportions, and Wilcoxon-Mann-Whitney and chi-square tests are used to examine differences between sex work and sexual behavior measures by income source. Participants were engaged in sex work for 5.0 years (IQR = 2.3-10.0), and earned 3000 (IQR = 2000-8000) Rupees (India engage in high levels of sexual risk for HIV/STIs. Money appears to be a driving factor for engaging in sex work and condomless sex with clients. HIV prevention interventions with MSW should focus on facilitating skills that will support their ability to negotiate sexual safety in the context of monetary disincentives.

    Full Text Available Background: Male sex workers (MSWs have recently been recognized as an important risk group for sexually transmitted infections (STIs including human immunodeficiency virus (HIV infection. Although there are global studies on MSWs, few such studies describe the behavioral patterns and STIs among this population in India. Methods: MSWs were evaluated at the Humsafar trust, a community based organization situated in suburban Mumbai, India. We report on the demographics, sexual behaviors, and STIs including HIV of these sex workers. Results: Of the 75 MSWs, 24 were men and 51 were transgenders. The mean age of the group was 23.3 (+ 4.9 years. About 15% were married or lived with a permanent partner. Of these individuals, 85% reported sex work as a main source of income and 15% as an additional source. All the individuals reported anal sex (87% anal receptive sex and 13% anal insertive sex. About 13% of MSWs had never used a condom. The HIV prevalence was 33% (17% in men vs 41% in transgenders, P = 0.04. The STI prevalence was 60% (58% in men vs 61% in transgenders, P = 0.8. Syphilis was the most common STI (28% in these MSWs. HIV was associated with being a transgender (41 vs 17%, P = 0.04, age > 26 years (57 vs 28%, P = 0.04, more than one year of sex work (38 vs 8%, P = 0.05, and income < Rs. 2000 per month (62 vs 27%, P = 0.02. Conclusions: The MSWs have high-risk behaviors, low consistent condom use, and high STI/HIV infections. These groups should be the focus of intensive public health interventions aimed at reduction of risky sexual practices, and STI/HIV prevention and care.

    There is scarce research on male sex workers in the context of alcohol use. While heavy alcohol use has been established as a risk factor for HIV and STI infections among men who have sex with men (MSM), men who engage in sex work with other men, particularly from the Global South, have not been included in these studies. Moreover, studies among male sex workers in Asia often do not explore migration contexts of these men. The objective of this exploratory study is to examine the prevalence and correlates of heavy alcohol use among migrant and non-migrant male sex workers in Bangkok and Pattaya, Central Thailand. Between August and October 2015, 18-24 year-old migrant and non-migrant male sex workers (n = 212) were recruited from various male sex work-identified venues (bars, clubs, massage parlors, and go-go bars) to take an interviewer-administered cross-sectional survey in Bangkok and Pattaya, Thailand. Measures were adapted from previous studies in similar populations and included structured questions across four domains, including demographic characteristics, alcohol use, stimulant use, and sexual behaviors. Multivariable logistic regression assessed the independent associations between heavy alcohol use (heavy versus not heavy) and demographic characteristics, stimulant use and sexual behavior. Heavy alcohol use was prevalent among one-third of participants. Heavy alcohol use was positively associated with male sex workers who were non-migrant and Thai, currently using stimulants, having 15 or more male clients in the past month and having first consumed alcohol at age 15 years or younger. Current HIV prevention efforts should consider subpopulations of MSM, including male sex workers and migrants, as well as other risk behaviors like alcohol, as important contexts for HIV and STI risks.

    Male sex workers (MSW) are a particularly high-risk subset of men who have sex with men in Lebanon and report higher numbers of sex partners and lower rates of condom use. The purpose was to explore the factors influencing sexual risk behaviors and HIV testing among MSW. Qualitative interviews were conducted with 16 MSW living in Beirut and working in bathhouses (hammam) or as escorts; content analysis identified emergent themes. Escorts reported more consistent condom use with clients and HIV testing than hammam MSW, with influential factors including HIV risk knowledge and perceived risk susceptibility, job security, and internalized stigma and related feelings of self-worth and fatalism regarding health and HIV risk. In contrast, both groups of MSW typically opted not to condoms with nonclient sex partners, in an effort to differentiate sex for work versus pleasure. The uptake of HIV testing was limited by concerns about the confidentiality of the test results and fear of repercussions of a positive test result for their health and employment. The respondents described an insular existence within the sex work culture, in part to limit exposure to stigma, which has implications for access to support as well as the influence of peer norms regarding sexual risk behavior and health seeking behaviors such as HIV testing. Further research is needed to tailor prevention and HIV testing efforts to reflect the distinct sexual health “cultures” that distinguish these two populations of MSW in Lebanon. PMID:25950906

    Full Text Available The increasing burden of sexually transmitted infections (STIs including HIV and syphilis among male sex workers (MSWs is a major global concern. The aim of our study was to evaluate the difference between MSWs and non-commercial MSMs in China.During 2008-09, in a cross-sectional study, 2618 adult MSM were recruited through respondent-driven and snowball sampling from seven cities of China. Information regarding socio-demographics, risk behaviors, HIV-related knowledge and STI-related symptoms were collected and participants were tested for HIV and syphilis.Among 2618 participating MSM, 9.97% sold sex to males. HIV prevalence was 7.45% (6.13% among MSWs and 7.59% among non-MSW MSM and syphilis prevalence was 14.32% (10.73% for MSWs and 14.72% for non-MSW MSM. Compared to non-MSW MSM, MSWs were more likely to be younger (adjusted odds ratio: aOR = 0.91, 95% confidence interval: 95%CI=0.88-0.93, never married (aOR = 4.38, 95% CI = 2.38-6.80, less educated, heterosexual (aOR = 13.04, 95% CI = 6.08-27.95, less knowledgeable regarding HIV (aOR = 0.70, 95% CI=0.51-0.96, experiencing symptoms of STI (aOR = 2.16, 95% CI = 1.47-3.19, engaging in condomless vaginal intercourse (aOR = 2.16, 95% CI = 1.47-3.19 and less likely to engage in condomless anal intercourse (aOR = 0.62, 95% CI = 0.46-0.85.High HIV and syphilis prevalence warranted urgent intervention targeting MSWs as a separate sentinel group for efficient surveillance owing to their different distribution from non-MSW MSM. Although male sex workers and non-commercial homosexuals have similar rates of HIV and syphilis, MSWs have different characteristics which should be considered in designing intervention programs targeting them.

    In Vietnam, the co-occurrence (i.e., "syndemic") of psychosocial factors (e.g., depression and substance use) may disproportionately burden male sex workers and increase their HIV risk. A comprehensive survey was conducted among 300 male sex workers in Ho Chi Minh City, Vietnam in 2010. We performed logistic regression to examine the association between the syndemic variable-a count score of the number of five psychosocial conditions endorsed-and unprotected anal sex (UAS) in the past. One-third of participants reported any UAS, and 42 % reported ≥2 psychosocial health problems. In multivariable models, experiencing ≥4 psychosocial health problems was significantly associated with UAS. Every unit increase in number of psychosocial health problems was associated with a 25-30 % increase in odds of UAS. Understanding the syndemic condition and its association with HIV risk among male sex workers in Vietnam may lead to the development of more effective, comprehensive interventions.

  5. The embodiment of tourism among bisexually-behaving Dominican male sex workers.

    While theories of "structure" and social inequality have increasingly informed global health efforts for HIV prevention--with growing recognition of the linkages between large-scale political and economic factors in the distribution and impact of the HIV/AIDS epidemic--there is still little theorization of precisely how structural factors shape the very bodies and sexualities of specific populations and groups. In order to extend the theoretical understanding of these macro-micro linkages, this article examines how the growth of the tourism industry in the Dominican Republic has produced sexual practices and identities that reflect both the influence of large-scale structural processes and the resistant responses of local individuals. Drawing on social science theories of political economy, embodiment, and authenticity, I argue that an understanding of patterns of sexuality and HIV risk in the region requires analysis of how political-economic transformations related to tourism intersect with the individual experiences and practices of sexuality on the ground. The analysis draws on long-term ethnographic research with bisexually behaving male sex workers in two cities in the Dominican Republic, including participant observation, in-depth interviews, focus groups, and surveys. By examining the global and local values placed on these men's bodies and the ways sex workers use their bodies to broker tourists' pleasure, we may better understand how the large-scale structures of the tourism industry are linked to the specific meanings and practices of sexuality.

    We examined correlates of love and trust among female sex workers and their noncommercial male partners along the Mexico-US border. From 2011 to 2012, 322 partners in Tijuana and Ciudad Juárez, Mexico, completed assessments of love and trust. Cross-sectional dyadic regression analyses identified associations of relationship characteristics and HIV risk behaviors with love and trust. Within 161 couples, love and trust scores were moderately high (median 70/95 and 29/40 points, respectively) and correlated with relationship satisfaction. In regression analyses of HIV risk factors, men and women who used methamphetamine reported lower love scores, whereas women who used heroin reported slightly higher love. In an alternate model, men with concurrent sexual partners had lower love scores. For both partners, relationship conflict was associated with lower trust. Love and trust are associated with relationship quality, sexual risk, and drug use patterns that shape intimate partners' HIV risk. HIV interventions should consider the emotional quality of sex workers' intimate relationships.

    In Peru, there are few studies on male sex workers (MSWs), and existing studies explore limited subgroups or offer limited information about MSWs' perspectives. This study provides in-depth perspectives from 40 MSWs who work in downtown Lima (Cercado) and in surrounding urban neighborhoods (non-Cercado) through interviews on their identities, lives, and HIV/STI (sexually transmitted infection) risks and vulnerabilities. Findings are that entry into sex work links economy and affection, particularly among Cercado MSWs. Continued sex work cements this link, making it difficult to exit sex work and establish goals. Ties between economics and affections influence MSWs' perceived HIV/STI risks, vulnerabilities, and prevention practices. Although Cercado MSWs report higher HIV/STI risks and vulnerabilities than non-Cercado peers, they report fewer prevention practices given inability to buy condoms and acceptance of client offers of higher payment, especially clients they feel affection for. MSWs need support to strengthen their self-perceptions and define and pursue their goals in order to improve their HIV/STI prevention practices, health, and well-being. © The Author(s) 2013.

    Introduction Globally, transgender women sex workers have a high prevalence of HIV and condomless receptive anal intercourse with male clients (CRAIMC). We investigated the prevalence of CRAIMC and factors associated with CRAIMC among transgender women sex workers in China. Methods In 2014, we anonymously interviewed 220 transgender women sex workers face to face in Shenyang, China. Those who self-reported as HIV negative or as having unknown HIV serostatus were invited to take up free, anonymous HIV rapid testing (n=183); 90 did so. Using CRAIMC in the last month as the dependent variable, three types of associated factors were investigated, in addition to background factors: feminizing medical interventions, sex work and perceptions related to condom use. Univariate and multiple logistic regression models were fitted. Results Of the participants, 16.8% self-reported as HIV positive and 9.1% were detected to be HIV positive through free HIV testing; 26.8% had had CRAIMC in the last month, 45.5% had performed sex work in other Chinese cities (last year), and 23.2% had had condomless anal intercourse with men who were non-clients. In the adjusted analysis, significant factors associated with CRAIMC (last month) included the following: 1) any feminizing medical intervention performed (adjusted odds ratio, AOR: 2.22); 2) sex-work-related factors, including recruitment of male clients most often at hotels (AOR: 5.02) and charge per episode of transactional sex (201 to 400 RMB, AOR: 0.27; reference group: ≤100 RMB); and 3) perceptions related to condom use, including perceived transgender identity's impact on condomless sex such as wearing feminine attire, concern about exposing their status as a transgender woman to male clients (AOR: 1.20) and perceived self-efficacy of consistent condom use with male clients (AOR: 0.56). Perceived self-efficacy of consistent condom use with male clients fully mediated the association between perceived transgender identity's impact

    Because consistent condom use is an effective strategy in the prevention of sexually transmitted infections and HIV transmission, it is important to examine social cognitive influences of consistent condom use not only among female sex workers (FSWs) but also among their male clients, for whom less is known. Because little is known about how HIV…

    There has been little theory-based research focusing on condom use among male clients of female sex workers (CFSW) in China. The current study applied social cognitive theory to condom use behaviors of CFSW in China. Face-to-face structured interviews were conducted among 584 CFSW recruited through snowball sampling. Bivariate and multivariate logistic regression models were applied to examine factors associated with consistent condom use. A minority (30.65 %) of respondents reported using condoms consistently with FSW, and 7 of 12 social cognitive dimensions/subdimensions were found to be significantly influential. The most significant factors were self-efficacy [adjusted prevalence ratio (APR) = 2.11, 95 %, CI = 1.74-2.43] and personal pleasure reduction (APR = 0.3, 95 % CI = 0.15-0.6). HIV-related knowledge, perceived HIV susceptibility, condom cost, condom efficacy, and embarrassment of carrying condoms were not associated with consistent condom uses with FSW. Findings from the current study suggest future prevention programs should target sex venues, and condom access should ensure both quantity and quality. Peer education should focus on knowledge education and peer norms, and knowledge education should include information on HIV infection severity and how to increase pleasure with condom use.

    Male clients of female sex workers (FSWs) in Tijuana, Mexico engage in high levels of unprotected sex. While behavioral change theories posit that self-efficacy predicts condom use, correlates of self-efficacy for condom use remain largely unstudied. We examined these correlates among male clients of FSWs in Tijuana. Eligible male clients were at least 18 years of age, HIV-negative, lived in Tijuana or San Diego, reported unprotected sex with a Tijuana FSW at least once in the past 4 months, and agreed to be treated for sexually transmitted infections (STIs). Participants completed an interviewer-administered questionnaire including demographics, substance use, psychosocial and psychosexual characteristics (e.g., outcome expectancies for negotiation of safer sex, social support, and sexual sensation seeking), and sexual behaviors. Participants also underwent HIV/STI testing. A stepwise hierarchical multiple regression analysis identified correlates of self-efficacy for condom use. Of 393 male clients, median age was 37 years. Participants were mostly Spanish-speaking and employed. Factors independently associated with higher self-efficacy for condom use were higher positive outcome expectancies for negotiation of safer sex, lower sexual sensation seeking scores, and higher social support scores. Both psychosocial and psychosexual factors may influence self-efficacy for condom use among male clients of FSWs. These factors represent central constructs in sociocognitive models that explain behavioral change and could be intervention targets for improving self-efficacy for condom use and, ultimately, safer sex behavior.

    In Vietnam, there is an emerging HIV epidemic among men who have sex with men (MSM). Male sex workers engage in high-risk sexual behaviours that make them particularly vulnerable to HIV infection. In 2010, 23 MSM in Ho Chi Minh City (HCMC) who recently received payment for sex with another man completed in-depth qualitative interviews exploring motivations for sex work, patterns of sex work disclosure and experiences of social stigma. Interviews were recorded, transcribed and translated into English and analysed using a qualitative descriptive approach. Low wages, unstable employment and family remittances were motivating factors for MSM in HCMC to sell sex. Participants described experiences of enacted and felt social stigma related to their involvement in sex work. In response, they utilised stigma management techniques aimed at concealment of involvement in sex work. Such strategies restricted sexual communication with non-paying sex partners and potentially limited their ability to seek social support from family and friends. Departing from decontextualized depictions of sex work disclosure, our findings describe how decisions to reveal involvement in sex work are shaped by social and structural factors such as social stigma, techniques to minimise exposure to stigma, economic imperatives and familial responsibilities.

    Knowledge about sexual practices and life experiences of men having sex with men in Kenya, and indeed in East Africa, is limited. Although the impact of male same-sex HIV transmission in Africa is increasingly acknowledged, HIV prevention initiatives remain focused largely on heterosexual and mother-to-child transmission. Using data from ten in-depth interviews and three focus group discussions (36 men), this analysis explores social and behavioural determinants of sexual risks among men who sell sex to men in Mombasa, Kenya. Analysis showed a range and variation of men by age and social class. First male same-sex experiences occurred for diverse reasons, including love and pleasure, as part of sexual exploration, economic exchange and coercion. Condom use is erratic and subject to common constraints, including notions of sexual interference and motivations of clients. Low knowledge compounds sexual risk taking, with a widespread belief that the risk of HIV transmission through anal sex is lower than vaginal sex. Traditional family values, stereotypes of abnormality, gender norms and cultural and religious influences underlie intense stigma and discrimination. This information is guiding development of peer education programmes and sensitisation of health providers, addressing unmet HIV prevention needs. Such changes are required throughout Eastern Africa.

    We use data collected from a sample of 400 male clients of female sex workers (FSW) to examine their HIV testing behavior. We present frequencies of HIV testing and used bivariate and multivariable analyses to assess its socio-demographic, behavioral, and psychosocial correlates. We found that the majority (55 %) of male clients of FSW in Tijuana, Mexico had never had an HIV test and the prevalence of HIV testing within the past year was low (9 %). In multivariable analyses, significant correlates of having ever tested for HIV were higher age, higher HIV knowledge score, lower sexual compulsiveness score, lower misogynistic attitudes score, having a condom break during sex with a FSW, and higher frequency of sex with a FSW while she was high. Our findings represent an important starting point for developing effective interventions to address the need to promote HIV testing among this population.

    To investigate the prevalence and correlates of concurrent (overlapping) sexual partnerships among female sex workers (FSWs) and their non-commercial male partners in two Mexico-US border cities. A cross-sectional survey of FSWs and their non-commercial male partners was conducted in Tijuana and Ciudad Juárez, Mexico (2010-2011). Eligible FSWs and verified non-commercial partners were aged ≥18 years; FSWs had ever used hard drugs (lifetime) and recently exchanged sex for money, drugs or other goods (past month). Participants underwent baseline questionnaires obtaining dates of sex and condom use with ≤5 other recurring partners, including FSWs' regular clients. These dates were compared with dates of sex with enrolled study partners to determine overlap (ie, 'recurring' concurrency). Bivariate probit regression identified recurring concurrency correlates. Among 428 individuals (214 couples), past-year recurring concurrency prevalence was 16% and was higher among women than their non-commercial male partners (26% vs 6%). In 10 couples (5%), both partners reported recurring concurrency. The majority of couples (64%) always had unprotected sex, and most of the individuals (70%) with recurring concurrency 'sometimes' or 'never' used condoms with their concurrent partners. Recurring concurrency was positively associated with FSWs' income, men's caballerismo (a form of traditional masculinity) and men's belief that their FSW partners had sexually transmitted infections (STIs). Recurring concurrency, representing sustained periods of overlapping partnerships in which unprotected sex was common, should be addressed by couple-based STI prevention interventions.

    This study examines non-disclosure of HIV serostatus to sex partners among HIV-infected adults involved with transactional sex in Mumbai, India. Surveys were conducted with HIV-infected female sex workers (n = 211) and infected male clients (n = 205) regarding HIV knowledge, awareness of sex partners’ HIV serostatus, alcohol use, transactional sex involvement post-HIV diagnosis and non-disclosure of HIV serostatus. Gender-stratified multiple logistic regression models were used for analysis. Non-disclosure of one’s serostatus to all sex partners was reported by almost three-fifths of females and two-fifths of males. Predictors of non-disclosure included lack of correct knowledge about HIV and no knowledge of sex partners’ HIV serostatus. Among females, recent alcohol consumption also predicted non-disclosure. Among males, 10 + paid sexual partners in the year following HIV diagnosis predicted non-disclosure. Secondary HIV prevention efforts in India require greater focus on HIV disclosure communication and integrated alcohol and sexual risk reduction. PMID:22810892

    Male clients of female sex workers (FSWs) are at high risk for HIV. Whereas the HIV risks of alcohol use are well understood, less is known about hazardous alcohol use among male clients of FSWs, particularly in Mexico. We sought to identify risk factors for hazardous alcohol use and test associations between hazardous alcohol use and HIV risk behavior among male clients in Tijuana. Male clients of FSWs in Tijuana (n = 400) completed a quantitative interview in 2008. The AUDIT was used to characterize hazardous alcohol use. Multivariate logistic regression was used to determine independent associations of demographic and HIV risk variables with hazardous alcohol use (vs. non-hazardous). Forty percent of our sample met criteria for hazardous alcohol use. Variables independently associated with hazardous drinking were reporting any sexually transmitted infection (STI), having sex with a FSW while under the influence of alcohol, being younger than 36 years of age, living in Tijuana, and ever having been jailed. Hazardous drinkers were less likely ever to have been deported or to have shared injection drugs. Hazardous alcohol use is associated with HIV risk, including engaging in sex with FSWs while intoxicated and having an STI among male clients of FSWs in Tijuana. We systematically described patterns and correlates of hazardous alcohol use among male clients of FSWs in Tijuana, Mexico. The results suggest that HIV/STI risk reduction interventions must target hazardous alcohol users, and be tailored to address alcohol use. © American Academy of Addiction Psychiatry.

    In Vietnam's concentrated HIV epidemic, female sex workers (FSWs) are at increased risk for acquiring and transmitting HIV, largely through their male clients. A high proportion of males in Vietnam report being clients of FSWs. Studying HIV-related risk factors and prevalence among male clients is important, particularly given the potential for male clients to be a 'bridge' of HIV transmission to the more general population or to sex workers. Time-location sampling was used to identify FSW in Hanoi and Ho Chi Minh City, Vietnam's largest cities, in 2013-2014. Recruited FSWs were asked to refer one male client to the study. Demographic and risk behavior data were collected from FSWs and male clients by administered questionnaires. Biologic specimens collected from male clients were tested for HIV and opiates. Sampling weights, calculated based on the FSWs probability of being selected for enrolment, were applied to prevalence estimates for both FSWs and male clients. Logistic regression models were developed to obtain odds ratios for HIV infection among male clients. A total of 804 male clients were enrolled. Overall, HIV prevalence among male clients was 10.2%; HIV prevalence was 20.7% (95% confidence interval (CI) 15.0-27.9%) among those reporting a history of illegal drug use and 32.4% (95% CI 20.2-47.7%) among those with opioids detected in urine. HIV prevalence among male clients did not differ across 'bridging' categories defined by condom use with FSWs and regular partners over the previous 6 months. HIV among male clients was associated with a reported history of illegal drug use (OR 3.76; 95% CI 1.87-7.56), current opioid use (OR 2.55; 95% CI 1.02-6.36), and being referred by an FSW who self-reported as HIV-positive (OR 5.37; 95% CI 1.46-19.75). Self-reported HIV prevalence among enrolled FSWs was 2.8%. Based on HIV test results of male clients and self-reported status from FSWs, an estimated 12.1% of male client-FSW pairs were sero-discordant. These

    This article reports the results of a peer-led HIV prevention education and condom promotion program among transport workers in Kaolack, Senegal. As part of a 2-year longitudinal follow-up study, changes in men's AIDS-related knowledge, sexual behavior, condom use, and perceived barriers to condom use were evaluated by self-reports obtained from a systematic sample of transport workers interviewed before and after intervention. In addition to men's self-reports, preintervention and postintervention data on men's sexual and condom use behavior were gathered from a sample of licensed, commercial sex workers, who cited transport workers as their primary source of clients. Significant increases in men's HIV-related knowledge, previous use of condoms (from 30.4% to 53.5%), and consistent condom use with regular sex partners were documented over the study period, as were significant declines in perceived barriers to condom use. Though men reported significantly fewer sexual encounters with casual and commercial partners at follow-up compared to baseline, these data were unreliable. Women's postintervention reports indicate that a greater proportion of clients (including, but not limited to transport workers) "always" agree to use condoms (p money for unprotected sex (p taking greater initiative in the mechanics of condom use (supplying the condom, putting it on, and taking it off) than they did prior to the intervention, and significantly (p < .05) fewer women think that most of their clients know how to use a condom. The findings indicate that the peer-mediated intervention had a positive impact on several important outcomes measured and suggest that HIV prevention efforts need to focus on male client groups despite the logistical and methodological challenges.

    Full Text Available Female sex workers have been the target of numerous sexually transmitted infection (STI prevention strategies in China, but their male clients have attracted considerably less public health attention and resources. We sought to systematically assess the prevalence of HIV, syphilis, gonorrhea, and chlamydia among heterosexual male clients of female sex workers in China.Original research manuscripts were identified by searching Chinese and English language databases, and 37 studies analyzing 26,552 male clients were included in the review. Client STI prevalence across studies was heterogeneous. Pooled prevalence estimates and 95% confidence intervals were 0.68% (0.36-1.28% for HIV, 2.91% (2.17-3.89% for syphilis, 2.16% (1.46-3.17% for gonorrhea, and 8.01% (4.94-12.72% for chlamydia.The pooled prevalence estimates of HIV, syphilis, gonorrhea, and chlamydia among clients in this review exceed the prevalences previously reported among population-representative samples and low-risk groups in China. However, heterogeneity across studies and sampling limitations prevent definitive conclusions about how the prevalence of STIs in this population compares to the general population. These findings suggest a need for greater attention to clients' sexual risk and disease prevalence in China's STI research agenda in order to inform effective prevention policies.

    The HIV epidemic has had a widespread impact on global scientific and cultural discourses related to gender, sexuality, and identity. 'Male sex workers' have been identified as a 'key population' in the global HIV epidemic; however, there are methodological and conceptual challenges for defining inclusion and exclusion of transgender women within this group. To assess these potential implications, this study employs self-critique and reflection to grapple with the empiric and conceptual implications of shifting understandings of sexuality and gender within the externally re-created etic category of 'MSM' and 'transgender women' in epidemiologic HIV research. We conducted a sensitivity analysis of our previously published meta-analysis which aimed to identify the scope of peer-reviewed articles assessing HIV prevalence among male sex workers globally between 2004 and 2013. The inclusion of four studies previously excluded due to non-differentiation of cisgender male from transgender women participants (studies from Spain, Thailand, India, and Brazil: 421 total participants) increased the overall estimate of global HIV prevalence among 'men' who engage in sex work from 10.5% (95% CI 9.4-11.5%) to 10.8% (95% CI 9.8-11.8%). The combination of social science critique with empiric epidemiologic analysis represents a first step in defining and operationalising 'reflexive epidemiology'. Grounded in the context of sex work and HIV prevention, this paper highlights the multiplicity of genders and sexualities across a range of social and cultural settings, limitations of existing categories (i.e. 'MSM', 'transgender'), and their global implications for epidemiologic estimates of HIV prevalence.

    Female sex workers (FSWs) and their male clients are vulnerable to HIV infection and serve as a bridge in HIV transmission from the high-risk population to the general, low-risk population. To examine the factors of FSWs and male clients that correlate with the prevalence of HIV infection in the Chinese-Vietnamese border region, a cross-sectional survey was conducted in 2014 in the Hekou county of the Yunnan province of China. We performed a questionnaire survey to collect data on demographics, sexual behavior, and drug use. Blood and urine samples were collected for testing of HIV/sexually transmitted infections and drug use. We found that the prevalence of HIV infection among FSWs was 2.74%, and 15 male clients (2.62%) were HIV-positive. Multivariate logistic regression analysis revealed that herpes simplex virus type 2 infection was a risk factor for HIV infection in FSWs and male clients, suggesting the increased role of sexual transmission in the HIV epidemic in the Chinese-Vietnamese border region. Positive urinalysis result for amphetamine-type stimulants was observed in FSWs with HIV infection. History of drug use was correlated with HIV infection, which increased the HIV infection risk of male clients, confirming that drug use is an important target in future interventions for HIV prevention.

    Although sex work is frequently characterised as a practice with high risk for HIV and other STIs, little is known about the epidemiology of these infections among men who sell sex in Australia. This study reports the prevalence of chlamydia, gonorrhoea, infectious syphilis and HIV among men who have sex with men attending Australian publicly funded sexual health clinics and compares prevalence between sex workers and non-sex workers. From 2011 to 2014, de-identified patient data were extracted from 40 sexual health clinics in four Australian jurisdictions. The χ 2 and multiple logistic regression analyses were used to compare the prevalence of HIV and STIs among men attending these services who did and did not report sex work in the 12 months prior to consultation. All analyses were restricted to men who reported sex with other men and to each patient's first consultation at participating services. In total, 27 469 gay, bisexual and other men who have sex with men attended participating clinics; 443 (1.6%) reported sex work. At first consultation, 18% of sex workers and 17% of non-sex workers were diagnosed with HIV or an STI (p=0.4): 13% of sex workers were newly diagnosed with chlamydia, 15% with gonorrhoea, 0.5% with infectious syphilis and 0.6% with HIV. After controlling for demographic and behavioural factors, sex work was not independently associated with an HIV or STI diagnosis. These findings provide estimates of HIV and STI prevalence among men who sell sex in Australia and they challenge assumptions of sex work as inherently risky to the sexual health of gay bisexual and other men who have sex with men.

    Because consistent condom use is an effective strategy in the prevention of sexually transmitted infections and HIV transmission, it is important to examine social cognitive influences of consistent condom use not only among female sex workers (FSWs) but also among their male clients, for whom less is known. Because little is known about how HIV knowledge and condom attitudes affect condom use among male clients of FSWs in the Philippines, the main objective was to determine what characteristics (age, education, HIV knowledge, marital status) as well as attributes taken from protection motivation theory (perceived vulnerability, perceived severity, response efficacy) are significantly associated with consistent condom use among male clients of FSWs. Logistic regression analyses showed that the odds of using condoms consistently with an FSW are 13% higher for those with more years of education (adjusted odds ratio [AOR] = 1.13; 95% confidence interval [CI] = 1.03, 1.23), higher versus lower perception of severity of HIV/AIDS (AOR = 1.97; 95% CI = 1.04, 3.73), and had a higher score for response efficacy of condoms (AOR = 1.14; 95% CI = 1.03, 1.27). Future HIV/AIDS prevention interventions that address condom use among male clients should promote educational attainment and focus on awareness of the enduring negative health consequences of acquiring HIV/AIDS, as well as cultivate positive attitudes toward the efficacy of condom use, using creative social marketing strategies.

    Prague, the Czech Republic, is a popular sex tourism destination where sex work is decriminalized and young men offer sexual services at low prices relative to countries in Western Europe. This quantitative survey aimed to identify some of the demographic characteristics of these young men and their experiences in the sex industry. Internet escorts (N = 20) and sex workers in bars and clubs (N = 20) completed the survey anonymously in spring 2011. The results showed that sex workers in clubs often had troubled pasts and were forced into sex work to survive. They also reported incidents of violence, serious alcohol and drug use, as well as frequent gambling. The larger group of sex workers in Prague is made up of Internet escorts who have backgrounds that are not atypical for the average Czech youth. They had fewer problems with drugs and alcohol but were twice as likely as sex workers in bars and clubs to be victims of violent crime. Plans for interventions to help those who would change their line of work, as well as the importance of sociocultural context in understanding sex workers, are discussed.

    Access to biomedical HIV prevention technologies such as pre-exposure prophylaxis (PrEP) requires individuals to disclose risk behavior to clinicians, but experiences of discrimination and medical mistrust may limit disclosure among male sex workers and other MSM. We explored experiences of perceived discrimination, medical mistrust, and behavior disclosure among male sex workers compared to other men who have sex with men (MSM). We conducted 56 interviews with MSM and compared findings about medical mistrust, discrimination, and disclosure for 31 men who engaged in sex work vs. 25 men who did not. MSM who engaged in sex work reported more medical mistrust and healthcare discrimination due to issues beyond MSM behavior/identity (e.g., homelessness, substance use, poverty). MSM who did not report sex work described disclosing sex with men to clinicians more often. Both subgroups reported low PrEP awareness, but willingness to disclose behavior to obtain PrEP. Medical mistrust and perceived discrimination create barriers for sexual behavior disclosure to clinicians, potentially impeding access to PrEP and other forms of biomedical HIV prevention. These barriers may be higher among male sex workers compared to other MSM, given overlapping stigmas including sex work, substance use, homelessness, and poverty. An intersectionality framework for understanding multiple stigmas can help to identify how these dynamics may limit access to biomedical HIV prevention among male sex workers, as well as suggesting strategies for addressing stigmas to improve the delivery of PrEP and other HIV prevention approaches in this population.

    Male commercial sex workers are one of the high-risk community for blood-borne viruses. However, there are no data concerning the molecular status of Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), and Hepatitis C Virus (HCV) circulated among male commercial sex workers with injecting drug habits in Surakarta, Indonesia. Blood samples obtained from injecting drug male commercial sex workers in Surakarta were examined for HIV antibodies, HBsAg, and HCV antibodies, respectively, by immunological assays. Blood samples were also subjected to viral nucleic acid extraction and molecular detection of HIV, HBV, and HCV by nested (RT) PCRs. The PCR products were purified from agarose gels, and the nucleotide sequences were retrieved and molecular analyzed. HIV, HBV, and HCV were detected in 29.4% (10/34), 17.6% (6/34), and 52.9% (18/34), respectively. HIV CRF01_AE and B were found to be circulating in the community. HBV genotype B3 was predominated, followed by C1. HCV genotype 1a was predominated, followed by 1c, 3a, 1b, and 4a. HIV, HBV, and HCV were found circulating in the male commercial sex workers with injecting drug habits in Surakarta, Indonesia.

    The barrier HIV-stigma presents to the HIV treatment cascade is increasingly documented; however less is known about female and male sex worker engagement in and the influence of sex-work stigma on the HIV care continuum. While stigma occurs in all spheres of life, stigma within health services may be particularly detrimental to health seeking behaviors. Therefore, we present levels of sex-work stigma from healthcare workers (HCW) among male and female sex workers in Kenya, and explore the relationship between sex-work stigma and HIV counseling and testing. We also examine the relationship between sex-work stigma and utilization of non-HIV health services. A snowball sample of 497 female sex workers (FSW) and 232 male sex workers (MSW) across four sites was recruited through a modified respondent-driven sampling process. About 50% of both male and female sex workers reported anticipating verbal stigma from HCW while 72% of FSW and 54% of MSW reported experiencing at least one of seven measured forms of stigma from HCW. In general, stigma led to higher odds of reporting delay or avoidance of counseling and testing, as well as non-HIV specific services. Statistical significance of relationships varied across type of health service, type of stigma and gender. For example, anticipated stigma was not a significant predictor of delay or avoidance of health services for MSW; however, FSW who anticipated HCW stigma had significantly higher odds of avoiding (OR = 2.11) non-HIV services, compared to FSW who did not. This paper adds to the growing evidence of stigma as a roadblock in the HIV treatment cascade, as well as its undermining of the human right to health. While more attention is being paid to addressing HIV-stigma, it is equally important to address the key population stigma that often intersects with HIV-stigma.

    2015-01-01

    Technological change, particularly the growth of the Internet and smart phones, has increased the visibility of male escorts, expanded their client base and diversified the range of venues in which male sex work can take place. Specifically, the Internet has relocated some forms of male sex work away from the street and thereby increased market reach, visibility and access and the scope of sex work advertising. Using the online profiles of 257 male sex workers drawn from six of the largest websites advertising male sexual services in Australia, the role of the Internet in facilitating the normalisation of male sex work is discussed. Specifically we examine how engagement with the sex industry has been reconstituted in term of better informed consumer-seller decisions for both clients and sex workers. Rather than being seen as a 'deviant' activity, understood in terms of pathology or criminal activity, male sex work is increasingly presented as an everyday commodity in the market place. In this context, the management of risks associated with sex work has shifted from formalised social control to more informal practices conducted among online communities of clients and sex workers. We discuss the implications for health, legal and welfare responses within an empowerment paradigm.

    This article describes 3 distinct ethnocultural male-to-female transgender communities in New York City: the low-income African American/Black and Latina(o) House Ball community; low-income, often undocumented immigrant Asian sex workers; and middle-class White cross-dressers. These communities are highly socially isolated from each other and are more connected to their ethnocultural contexts than to an abstract and shared transgender identity. Whereas previous research either has viewed male-to-female transgender people as one monolithic group or has separated them into abstract racial categories unconnected to their communities and lifestyles, this article positions them within specific social networks, cultures, neighborhoods, and lifestyles. With regard to HIV vulnerabilities, violence, and rape, House Ball community members seemed to engage in the riskiest form of survival sex work, whereas Asian sex workers seemed to engage in moderate-risk survival sex work. White cross-dressers seemed to engage in very low-risk recreational sex work.

    Abstract Clients of female sex workers (CFSWs) are a bridge population for the spread of HIV and syphilis to low or average risk heterosexuals. Most studies have examined the point prevalence of these infections in CFSWs. Limited evidence suggests that older age CFSWs are at a higher risk of acquiring sexually transmitted diseases compared with younger clients. Thus, we sought to describe long-term trends in HIV, syphilis, and hepatitis C (HCV) to better understand how these infections differ by sex worker classification and client age. We also examined trends in HIV, syphilis, and HCV among categories of female sex workers (FSWs). We conducted serial cross-sectional studies from 2010 to 2015 in Guangxi autonomous region, China. We collected demographic and behavior variables. FSWs and their clients were tested for HIV, syphilis, and HCV antibodies. Positive HIV and syphilis serologies were confirmed by Western blot and rapid plasma regain, respectively. Clients were categorized as middle age (40–49 years) and older clients (≥50 years). FSWs were categorized as high-tier, middle-tier, or low-tier based on the payment amount charged for sex and their work venue. Chi-square test for trends was used for testing changes in prevalence over time. By 2015, low-tier FSWs (LTFSWs) accounted for almost half of all FSWs; and they had the highest HIV prevalence at 1.4%. HIV prevalence declined significantly for FSWs (high-tier FSW, P = 0.003; middle-tier FSWs; P = 0.021; LTFSWs, P HIV prevalence increased for older age clients (1.3%–2.0%, P = 0.159) while syphilis prevalence remained stable. HCV infections were halved among older clients in 3 years (1.7%–0.8%, P sex with men or intravenous drug use. Clients preferred LTFSWs, especially older clients (81.9%). Our results suggest that HIV and syphilis infections are increasing in older clients who prefer LTFSWs. HIV and syphilis are likely increasing in Guangxi Province through heterosexual transmission

    Based on combined methods, this study investigated substance use and HIV risk behaviors among kathoey sex workers (KSWs) in Bangkok, Thailand. The study found that only half of the KSW participants reported having been tested for HIV, and that except for one participant, all others had not seen health care providers in the past 12 months. About one third of the participants reported having engaged in unprotected anal sex with customers in the past six months. Almost all participants reported alcohol use, as well as having had sex with customers under the influence of alcohol. The prevalence of marijuana and ecstasy use in the past 12 months was high (32 and 36%, respectively); as was for ketamine (20%) and non-injecting methamphetamine (yaba) use (10%). A multiple regression analysis showed that the participants who were post-operative status, had used illicit drugs, or had been abused by their father and brothers were less likely to use condoms for anal sex with customers. Three quarters of the participants sent money to their families and 35% of the participants expressed their willingness to engage in unsafe sex when customers offer extra money. The qualitative interviews revealed that many identified as girl or kathoey in early age and had been exposed to transphobia and violence from father and brothers. Some reported support for gender transition from their mothers. More than half of the participants currently had difficulties in living as kathoey, such as challenges in the job market and relationship with family members. Family obligation for sending money and the Buddhist concept of karma were discussed in relation to risk behaviors among KSWs. The study provided implications for facilitating HIV testing and developing future HIV prevention intervention programs for KSWs in Thailand.

    Tijuana is situated on Mexico's northern border with the U.S., where sex work is quasi-legal. Whereas previous work has focused on the risk behaviors of female sex workers (FSWs), less is known about the risk behaviors of their male clients. Further, research has not examined structural factors as moderators of the association between substance use and condom use, including the contexts in which sex takes place. The purpose of the current study is to examine whether having sex with FSWs in a bar moderates the link between alcohol intoxication during sex and condom use. We recruited 375 male clients of FSWs in Tijuana, Mexico from San Diego, California and Tijuana. Using computer assisted interviewing, we surveyed participants on their alcohol use, condom use, and physical contexts of sex with FSWs in the past 4 months. Results showed that more frequent intoxication during sex with FSWs is associated with more unprotected sex, but only among clients having sex with FSWs in a bar context. Results point to potential reasons for inconsistent condom use with FSWs in this context, including lower risk perceptions of sex with FSWs in bars. Future research should examine structural factors that underlie clients' risk behavior in bars in order to inform structural-level HIV prevention interventions.

    Objectives To determine sociodemographic and behavioral correlates of HIV infection among male clients of FSWs in Tijuana. Methods 400 men aged 18 or older who had paid or traded for sex with a FSW in Tijuana during the past 4 months were recruited in Tijuana’s “zone of tolerance,” where prostitution is practiced openly under a municipal permit system. Efforts were made to balance the sample between residents of the U.S. (San Diego County) and of Mexico (Tijuana). Participants underwent interviews and testing for HIV, syphilis, gonorrhea, and Chlamydia. Logistic regression identified correlates of HIV infection. Results Mean age was 36.6. One quarter had injected drugs within the previous 4 months. Lifetime use of heroin, cocaine and methamphetamine was 36%, 50% and 64%, respectively. Men had frequented FSWs for an average of 11 years, visiting FSWs an average of 26 times last year. In the past four months, one half reported having unprotected sex with an FSW; 46% reported frequently being high when having sex with an FSW. Prevalence of HIV, syphilis, gonorrhea, and Chlamydia was 4%, 2%, 2.5% and 7.5%; 14.2% were positive for at least one infection. Factors independently associated with HIV infection were living in Mexico, ever using methamphetamine, living alone, and testing positive for syphilis. Conclusions Male clients of FSWs in Tijuana had a high sex and drug risk profile. While STI prevalence was lower than among FSWs, HIV prevalence was comparable, suggesting the need for interventions among clients to prevent spread of HIV and STIs. PMID:19584699

    It is still a small body of research that directly addresses female sex workers' relationships with their regular commercial male partners. I used ethnographic data from Nairobi, Kenya to interrogate motivations and strategies for recruiting and retaining regular male clients among female sex workers (FSWs). Regular commercial male partners, popularly called customer care, wera or wesh by Nairobi's FSWs, played diverse roles in their lives. Client retention enabled sex workers to manage the risk of reduced marriage prospects, guaranteed them steady work, livelihoods, and incomes, and prevented their victimization and harassment. To retain clients, sex workers obliged them a great deal, pretended they had quit prostitution, and sometimes resorted to magical practices. However, these strategies were also accompanied by risks that reinforced the vulnerability of sex workers. Lack of critical attention to sex workers' practices for managing perceived risks in their particular type of work may hamper current programmatic efforts to make their job safer.

    The stigma associated with male sex workers (MSW) hinders the prevention, treatment, and care of HIV infection in this population. These factors make social and public health resources less accessible to MSW. To improve the effectiveness of prevention strategies, this study examines social factors such as educational level, country of origin, and sexual orientation. Semi-structured interviews of 100 MSW in Castellón and Valencia (Spanish cities) indicate that knowledge of HIV transmission is good; nevertheless, MSW significantly overestimate or underestimate some sexual practices. Levels of condom use are high; notably, they are higher during anal sex. Levels of condom use are lower with intimate partners than with clients. MSW do not present differences in terms of the socio-demographic variables analyzed and sexual orientation. Furthermore, regression analyses are not significant. These results offer more accurate profiles of MSW than were previously available, which will ultimately help improve the effectiveness of prevention programs.

    Objective: To understand HIV-1 subtype characteristics and transmission clusters in elderly male clients and female sex workers (FSWs) of low-cost commercial sex venues in Guangxi Zhuang Autonomous Region, China. Methods: A cross sectional survey was conducted in FSWs and elderly male clients (≥50 years) of low-cost commercial sex venues in 4 cities and 9 counties in Guangxi Zhuang Autonomous Region by convenient sampling in 2012. The blood sample was collected from each case for HIV-1 antibody detection. The pol gene fragments were amplified and sequenced from viral RNA template extracted from plasma samples. The phylogenetic tree was constructed and the subtypes were identified. Results: A total of 4 048 elderly male clients and 784 FSWs were surveyed, and 116 HIV-1 infections were detected, the positive rate was 2.5% (103/4 048) in the clients and 1.7% (13/784) in FSWs. The gene amplification and sequencing of HIV-1 detected in 84 blood samples indicated that 53 pol gene sequences were successfully determined (48 blood samples from elderly male clients and 5 blood samples from FSWs). Among 53 pol sequences, 48(90.6% ), 4(7.5% ), and 1(1.9% ) sequences were identified as CRF01_AE, CRF08_BC, and CRF07_BC, respectively. Two transmission clusters were identified among CRF01_AE, including 4 sub-clusters. One transmission cluster was identified among CRF08_BC. The transmission cluster or sub-cluster were from the infected individuals at same low-cost commercial sex venue, or different low-cost commercial sex venues in the same town, or same place, or adjacent villages and towns. Conclusions: CRF01_AE was the predominant HIV-1 subtype among elderly male clients and FSWs of low-cost commercial sex venues in Guangxi Zhuang Autonomous Region, circulating in same venue or adjacent villages and towns. The HIV-1 positive male clients and FSWs might play an important role in the spread of the strains.

    Female sex workers (FSWs) may benefit from pre-exposure prophylaxis (PrEP) including microbicides for HIV prevention. Since adherence is a key factor in PrEP efficacy, we explored microbicide acceptability and potential barriers to use within FSWs' intimate relationships in Tijuana and Ciudad Juárez, Mexico, where HIV prevalence is increasing. FSWs and their verified intimate (non-commercial) male partners completed quantitative and qualitative interviews from 2010 to 2012. Our complementary mixed methods design followed an iterative process to assess microbicide acceptability, explore related relationship dynamics and identify factors associated with concern about male partners' anger regarding microbicide use. Among 185 couples (n=370 individuals), interest in microbicides was high. In qualitative interviews with 28 couples, most participants were enthusiastic about microbicides for sex work contexts but some explained that microbicides could imply mistrust/infidelity within their intimate relationships. In the overall sample, nearly one in six participants (16%) worried that male partners would become angry about microbicides, which was associated with higher self-esteem among FSWs and lower self-esteem and past year conflicts causing injury within relationships among men. HIV prevention interventions should consider intimate relationship dynamics posing potential barriers to PrEP acceptability and adherence, involve male partners and promote risk communication skills.

  3. A new public health context to understand male sex work.

    Researching male sex work offers insight into the sexual lives of men and women while developing a more realistic appreciation for the changing issues associated with male sex work. This type of research is important because it not only reflects a growing and diversifying consumer demand for male sex work, but also because it enables the construction of knowledge that is up-to-date with changing ideas around sex and sexualities. This paper discusses a range of issues emerging in the male sex industry. Notably, globalisation and technology have contributed to the normalisation of male sex work and reshaped the landscape in which the male sex industry operates. As part of this discussion, we review STI and HIV rates among male sex workers at a global level, which are widely disparate and geographically contextual, with rates of HIV among male sex workers ranging from 0% in some areas to 50% in others. The Internet has reshaped the way that male sex workers and clients connect and has been identified as a useful space for safer sex messages and research that seeks out hidden or commonly excluded populations. We argue for a public health context that recognises the emerging and changing nature of male sex work, which means programs and policies that are appropriate for this population group. Online communities relating to male sex work are important avenues for safer sexual messages and unique opportunities to reach often excluded sub-populations of both clients and male sex workers. The changing structure and organisation of male sex work alongside rapidly changing cultural, academic and medical discourses provide new insight but also new challenges to how we conceive the sexualities of men and male sex workers. Public health initiatives must reflect upon and incorporate this knowledge.

    In India men who have sex with men and engage in sex work (i.e., male sex workers; MSW) have a high risk of transmitting HIV. Globally, sex workers have become more spatially mobile due to advances in mobile-phone technology. In 2012 in-depth qualitative feedback was garnered from 40 interviews with MSW and four focus groups with 35 key informants (KIs) who had expert knowledge of the local MSW community to inform the design of an HIV-prevention intervention among MSW in Chennai, India. All MSW were recruited during outreach by employees of a Chennai-based organization for MSM (men who have sex with men). The data were analyzed using a descriptive qualitative approach. MSW and KIs discussed the need for intervention content that went beyond basic HIV psychoeducation. They emphasized the importance of addressing psychological distress, alcohol-related risk, and sexual communication skills. Concerns were raised about confidentiality, privacy, and scheduling. Participants endorsed a combination of in-person and mobile-phone-delivered sessions as well as the integration of mobile-phone messaging. These findings served as the basis for the development of a theoretically driven, manual-based intervention incorporating mobile phones. An open pilot assessed the feasibility and acceptability of the intervention with eight MSW. Assessments and HIV testing were administered at baseline, 3, and 6 months post-baseline. Exit interviews were conducted at the conclusion of the intervention. Retention for session attendance and assessment follow-up was 100 %. There was a high level of acceptability for the format, structure, and content. These data show initial promise, feasibility, and acceptability of the intervention.

    The purpose of this study is to compare the evolution of risky factors related to HIV infection among Male Sex Workers (MSW) in Spain between 2010 and 2015. Participants were 180 MSW: 100 in 2010 and 80 in 2015. Socio-demographic characteristics, condom use with clients and personal partners, and other aspects about HIV infection were explored (serostatus, HIV information, perceived risk and fear, and drug use). The proportion of Spanish MSW (nonimmigrants) (5.5 vs. 62.5 %), educational level (19.8 vs. 40.5 % reported university degree), and the percentage of self-identified as bisexual (20.2 vs. 55.8 %) increased in 2015, whereas the percentage of MSW who self-identified as sex workers (62 vs. 25.8 %) decreased. The percentage of condom use has decreased during oral sex (76.8 vs. 35.5 %), vaginal sex (97.6 vs. 50.7 %) and insertive (99.6 vs. 92.2 %) and receptive (99.7 vs. 93 %) anal sex. The proportion of MSW living with HIV climbed from 1.1 to 13.6 %. The possible influence of economic crisis over MSW's profile changes in the 5-year period, and the necessity of more efficient health strategies based on culture and sexual orientation are discussed. The evolution observed indicates that this population is still at high risk for HIV and STI, therefore governmental resources have to be increased due the consequences among MSW and general society.

    Full Text Available Abstract Background Previous research has linked alcohol use with an increased number of sexual partners, inconsistent condom use and a raised incidence of sexually transmitted infections (STIs. However, alcohol measures have been poorly standardised, with many ill-suited to eliciting, with adequate precision, the relationship between alcohol use and sexual risk behaviour. This study investigates which alcohol indicator - single-item measures of frequency and patterns of drinking ( > = 6 drinks on 1 occasion, or the Alcohol Use Disorders Identification Test (AUDIT - can detect associations between alcohol use and unsafe sexual behaviour among male sex workers. Methods A cross-sectional survey in 2008 recruited male sex workers who sell sex to men from 65 venues in Mombasa district, Kenya, similar to a 2006 survey. Information was collected on socio-demographics, substance use, sexual behaviour, violence and STI symptoms. Multivariate models examined associations between the three measures of alcohol use and condom use, sexual violence, and penile or anal discharge. Results The 442 participants reported a median 2 clients/week (IQR = 1-3, with half using condoms consistently in the last 30 days. Of the approximately 70% of men who drink alcohol, half (50.5% drink two or more times a week. Binge drinking was common (38.9%. As defined by AUDIT, 35% of participants who drink had hazardous drinking, 15% harmful drinking and 21% alcohol dependence. Compared with abstinence, alcohol dependence was associated with inconsistent condom use (AOR = 2.5, 95%CI = 1.3-4.6, penile or anal discharge (AOR = 1.9, 95%CI = 1.0-3.8, and two-fold higher odds of sexual violence (AOR = 2.0, 95%CI = 0.9-4.9. Frequent drinking was associated with inconsistent condom use (AOR = 1.8, 95%CI = 1.1-3.0 and partner number, while binge drinking was only linked with inconsistent condom use (AOR = 1.6, 95%CI = 1.0-2.5.

    To determine sociodemographic and behavioral correlates of HIV infection among male clients of female sex workers (FSWs) in Tijuana. Four hundred men aged 18 years or older who had paid or traded for sex with a FSW in Tijuana during the past 4 months were recruited in Tijuana's 'zone of tolerance,' where prostitution is practiced openly under a municipal permit system. Efforts were made to balance the sample between residents of the United States (San Diego County) and of Mexico (Tijuana). Participants underwent interviews and testing for HIV, syphilis, gonorrhea, and Chlamydia. Logistic regression identified correlates of HIV infection. Mean age was 36.6 years. One-quarter had injected drugs within the previous 4 months. Lifetime use of heroin, cocaine, and methamphetamine was 36, 50, and 64%, respectively. Men had frequented FSWs for an average of 11 years, visiting FSWs an average of 26 times last year. In the past 4 months, one-half reported having unprotected sex with a FSW; 46% reported being high fairly or very often when having sex with a FSW. Prevalence of HIV, syphilis, gonorrhea, and Chlamydia was 4, 2, 2.5, and 7.5%; 14.2% were positive for at least one infection. Factors independently associated with HIV infection were living in Mexico, ever using methamphetamine, living alone, and testing positive for syphilis. Male clients of FSWs in Tijuana had a high sex and drug risk profile. Although sexually transmitted infection prevalence was lower than among FSWs, HIV prevalence was comparable suggesting the need for interventions among clients to prevent spread of HIV and sexually transmitted infections.

    Clients of female sex workers (FSWs) possess a high potential of transmitting HIV and other sexually transmitted infections from high risk FSWs to the general population. Promotion of safer sex practices among the clients is essential to limit the spread of HIV/AIDS epidemic. The aim of this study is to estimate the prevalence of consistent condom use (CCU) among clients of FSWs and to assess the factors associated with CCU in Tamil Nadu. 146 male respondents were recruited from the hotspots who reportedly had sex with FSWs in exchange for cash at least once in the past one month. Data were analyzed using bivariate and multivariate methods. Overall, 48.6 and 0.8 percent clients consistently used condoms in the past 12 months with FSWs and regular partners, respectively. Logistic regression showed that factors such as education, peers' use of condoms, and alcohol consumption significantly influenced clients' CCU with FSWs. Strategies for safe sex-behaviour are needed among clients of FSWs in order to limit the spread of HIV/AIDS epidemic in the general population. The role of peer-educators in experience sharing and awareness generation must also be emphasized. PMID:26316978

  9. Is audio computer-assisted self-interview (ACASI useful in risk behaviour assessment of female and male sex workers, Mombasa, Kenya?

    Full Text Available Audio computer-assisted self-interview (ACASI may elicit more frequent reporting of socially sensitive behaviours than face-to-face (FtF-interview. However, no study compared responses to both methods in female and male sex workers (FSW; MSW in Africa.We sequentially enrolled adults recruited for an HIV-1 intervention trial into a comparative study of ACASI and FtF-interview, in a clinic near Mombasa, Kenya. Feasibility and acceptability of ACASI, and a comparative analysis of enrolment responses between ACASI and FtF on an identical risk assessment questionnaire were evaluated. In total, 139 women and 259 men, 81% of eligible cohort participants, completed both interviews. ACASI captured a higher median number of regular (2 vs. 1, p<0.001, both genders and casual partners in the last week (3 vs. 2, p = 0.04 in women; 2 vs. 1, p<0.001 in men. Group sex (21.6 vs. 13.5%, p<0.001, in men, intravenous drug use (IDU; 10.8 vs. 2.3%, p<0.001 in men; 4.4 vs. 0%, p = 0.03 in women, and rape (8.9 vs. 3.9%, p = 0.002, in men were reported more frequently in ACASI. A surprisingly high number of women reported in ACASI that they had paid for sex (49.3 vs. 5.8%, p<0.001. Behaviours for recruitment (i.e. anal sex, sex work, sex between males were reported less frequently in ACASI. The majority of women (79.2% and men (69.7% felt that answers given in ACASI were more honest. Volunteers who were not able to take ACASI (84 men, and 37 women mostly lacked reading skills.About 1 in 5 cohort participants was not able to complete ACASI, mostly for lack of reading skills. Participants who completed ACASI were more likely to report IDU, rape, group sex, and payment for sex by women than when asked in FtF interview. ACASI appears to be a useful tool for high risk behaviour assessments in the African context.

    To examine the HIV/sexually transmitted infection (STI)-related risk behaviours among community-based female sex workers (FSWs) and their clients in Yunnan Province, China, we performed a cross-sectional study of 705 FSWs and 100 male clients. We found that HIV seroprevalence among FSWs was 13.0% and the most prevalent STI was herpes simplex virus type 2 (HSV-2) (71.1%), followed by Chlamydia trachomatis (18.1%) and syphilis (8.8%). The 20% of FSWs who reported injection drug use also reported needle-sharing behaviours in the last three months. Drug-using FSWs had substantially higher HIV and HSV-2 prevalence, serviced more clients and had a longer history of sex work than non-using FSWs. In total, 57.0% of male clients did not consistently use condoms with FSWs, 2.0% reported illicit drug use and 17.0% had STI symptoms in the last year. The dual risk behaviours of drug-using FSWs and clients place them at greater risk of HIV infection. Intervention programmes must adopt comprehensive methods.

    Male-to-female transgender sex workers (TSW) have been identified as a key population at risk for HIV. This study examined risk behaviors and HIV prevalence among TSW, and described health services use. A participatory cross-sectional survey was conducted with 125 TSW recruited in locations and networks where sex workers congregate. HIV-risk behaviors were common among participants. Inconsistent condom use with clients in the previous month was reported by 12.0% of participants and was associated with Portuguese nationality, inconsistent condom use with non-paying partners and not been reached by HIV prevention programs in the previous year. Ever use of psychoactive substances was reported by 61.6% of participants and was associated with being non-employed, doing full-time sex work, having higher number of non-paying partners and having never used health services. Also, ever use of psychoactive substances was negatively associated with older age and Portuguese nationality. About 34% of the participants reported having not been tested in the previous 12 months; 20.2% never used the health services. Overall, 14.9% (95%CI: 8.0-21.0%) reported being HIV-positive. Of those, 22.2% (95%CI: 1.0-43.5%) had unprotected sex with clients in the previous month, 26.7% (95%CI: 1.3-52.0%) had unprotected sex with non-paying partners in the previous year, 13.3% (95%CI: 0.0-33.0%) had ever injected drugs, 60.0% (95%CI: 23.0-97.0%) reported a past STI and 33.3% (95%CI: 2.0-64.6%) had currently HIV/STI co-infection. The socioeconomic, relational or partnering, and structural contexts conducive to increased risk are warranting further investigation. This knowledge would be valuable to inform prevention programs. HIV interventions, including secondary prevention, should address specific needs of TSW. Outreach initiatives aimed to reach TSW who are difficult to access can play a role in promoting access to health services and reducing HIV infection and transmission.

    Pre- and post-exposure prophylaxes (PrEP and PEP) can reduce the risk of HIV acquisition, yet often are inaccessible to and underutilized by most-vulnerable populations, including sex workers in sub-Saharan Africa. Based on in-depth interviews with 21 female and 23 male HIV-negative sex workers in Mombasa, Kenya, we found that awareness and knowledge of PrEP and PEP were low, although willingness to use both was high. Participants felt PrEP would be empowering and give added protection against infection, although some expressed concerns about side effects. Despite PEP's availability, few knew about it and even fewer had used it, but most who had would use it again. Sex workers valued confidentiality, privacy, trustworthiness, and convenient location in health services and wanted thorough HIV/STI assessments. These findings suggest the importance of situating PrEP and PEP within sex worker-friendly health services and conducting outreach to promote these biomedical prevention methods for Kenyan sex workers.

    To describe the sociodemographic and sex work characteristics, recent sexual practices, HIV risk perception and testing history, and HIV and syphilis prevalence of Cercado (downtown) and non-Cercado (close urban) male sex workers (MSWs) in Lima, Peru. Eighty-nine MSWs completed a self-administered survey and participated in HIV and syphilis testing. Cercado MSWs had significantly lower median weekly earnings than non-Cercado MSWs (US$43 vs US$72, p=0.04). Most non-Cercado MSWs (81%) reported only insertive anal intercourse with male/transgender partners, while Cercado MSWs primarily reported only insertive (52%) or insertive and receptive (45%) anal intercourse (p=0.03). Consistent condom use was low with insertive and receptive anal intercourse in both subgroups. Among MSWs with recent female partners, condom use with the last partner was lower among Cercado versus non-Cercado MSWs for vaginal sex (37% vs 65%, p=0.04) and anal sex (27% vs 80%, p=0.01). More Cercado than non-Cercado MSWs (57% vs 42%) perceived high HIV risk (p=0.05) and Cercado MSWs had a much higher prevalence than non-Cercado MSWs of HIV (23% vs 4%, p=0.04) and syphilis (22% vs 0%, p=0.02) infections. MSWs in Lima are diverse and Cercado MSWs are 'just getting by,' engaging in more risk behaviours, and more likely to have HIV/STIs. Future research should identify, describe and carry out HIV/STI testing with broader groups of MSWs and their client and non-client partners. Prevention efforts should provide HIV/STI risk reduction education for MSWs and related subgroups who are currently not targeted such as female partners.

    Aotearoa (New Zealand) is the only country in the world to have decriminalized sex work. The Prostitution Reform Act (PRA henceforth) was enacted in 2003 with the aim to safeguard the human rights of sex workers, and create a framework that is conducive to public health. Skeptics of this policy argue that the law reform was targeting indoor workers while the livelihood of street-based sex workers did not see significant improvements (Justice Acts, 2014).

    Full Text Available There is evidence that HIV prevention programs for sex workers, especially female sex workers, are cost-effective in several contexts, including many western countries, Thailand, India, the Democratic Republic of Congo, Kenya, and Zimbabwe. The evidence that sex worker HIV prevention programs work must not inspire complacency but rather a renewed effort to expand, intensify, and maximize their impact. The PLOS Collection "Focus on Delivery and Scale: Achieving HIV Impact with Sex Workers" highlights major challenges to scaling-up sex worker HIV prevention programs, noting the following: sex worker HIV prevention programs are insufficiently guided by understanding of epidemic transmission dynamics, situation analyses, and programmatic mapping; sex worker HIV and sexually transmitted infection services receive limited domestic financing in many countries; many sex worker HIV prevention programs are inadequately codified to ensure consistency and quality; and many sex worker HIV prevention programs have not evolved adequately to address informal sex workers, male and transgender sex workers, and mobile- and internet-based sex workers. Based on the wider collection of papers, this article presents three major clusters of recommendations: (i HIV programs focused on sex workers should be prioritized, developed, and implemented based on robust evidence; (ii national political will and increased funding are needed to increase coverage of effective sex worker HIV prevention programs in low and middle income countries; and (iii comprehensive, integrated, and rapidly evolving HIV programs are needed to ensure equitable access to health services for individuals involved in all forms of sex work.

    A previous time-location sampling survey (TLS) was performed in 2008 to evaluate the HIV or syphilis infection rate among male sex workers (MSWs) and non-commercial men who have sex with men (ncMSM) in Shenzhen, China. This is a second TLS performed in 2014. This article describes the findings and changes in the prevalence of HIV and syphilis. TLS was used to collect information as a second cross-sectional survey to an earlier TLS assessment. Data on behavior (e.g., sexual history and sexual behavior) were analyzed. Blood specimens were drawn for HIV and syphilis testing. To determine the changes in the prevalence of HIV and syphilis, we analyzed these results and compared them to the results of our first survey. A total of 965 participants were recruited, including 489 MSWs and 476 ncMSM. Overall, the prevalence of HIV was 9.7%: 2.9% for MSWs and 16.8% for ncMSM (PHIV prevalence in MSWs decreased from 4.5% in 2008 to 2.9% in 2014 (P = 0.143) but increased in ncMSM (7.0% in 2008 vs 16.8% in 2014, PHIV and syphilis in MSWs but not in ncMSM. The study indicated the need for continued efforts to improve public health, particularly to counter the rising rate of HIV in ncMSM.

  19. Actions of female sex workers who experience male condom failure during penetrative sexual encounters with clients in Cape Town: Implications for HIV prevention strategies

    2017-01-01

    Background Condom failure has always been found to coexist with condom usage, especially among sex workers. Objective To describe the actions of female sex workers when they are faced with situations of condom failure. Methods Using the survey design, the participants were selected through the snowball sampling method. Their responses were obtained using a structured questionnaire. A total of 100 questionnaires were analysed. Results With respect to the immediate actions of sex workers after condom failure, 36% of the respondents continued with the sexual encounter after noticing that the condom was broken. Another 36% stopped immediately when they noticed that the condom had failed, but replaced the condom; 13% of the participants stopped the sexual encounter completely; 3% applied vaginal spermicidal foam; and 5% of the respondents stopped immediately and took a douche when they had the chance. For the actions within the next 24 hours of experiencing condom failure with a client, 53% of the participants did nothing; 4% sought counsel from a professional; 3% of the respondents took alcohol or drugs to forget the incident, 25% went to the clinic for assistance and 8% offered other responses. Conclusion While continuing the sexual encounter without replacing the condom, taking alcohol and drugs or doing nothing could increase the risk of contracting HIV; however, actions like stopping the sexual encounter completely and visiting a clinic or a professional could make a difference between staying HIV negative or seroconverting. There is a need for targeted intervention to address issues of inappropriate behaviours after experiencing condom failure. PMID:29568633

    Clients of female sex workers (CFSWs) are a bridge population for the spread of HIV and syphilis to low or average risk heterosexuals. Most studies have examined the point prevalence of these infections in CFSWs. Limited evidence suggests that older age CFSWs are at a higher risk of acquiring sexually transmitted diseases compared with younger clients. Thus, we sought to describe long-term trends in HIV, syphilis, and hepatitis C (HCV) to better understand how these infections differ by sex worker classification and client age. We also examined trends in HIV, syphilis, and HCV among categories of female sex workers (FSWs).We conducted serial cross-sectional studies from 2010 to 2015 in Guangxi autonomous region, China. We collected demographic and behavior variables. FSWs and their clients were tested for HIV, syphilis, and HCV antibodies. Positive HIV and syphilis serologies were confirmed by Western blot and rapid plasma regain, respectively. Clients were categorized as middle age (40-49 years) and older clients (≥50 years). FSWs were categorized as high-tier, middle-tier, or low-tier based on the payment amount charged for sex and their work venue. Chi-square test for trends was used for testing changes in prevalence over time.By 2015, low-tier FSWs (LTFSWs) accounted for almost half of all FSWs; and they had the highest HIV prevalence at 1.4%. HIV prevalence declined significantly for FSWs (high-tier FSW, P = 0.003; middle-tier FSWs; P = 0.021; LTFSWs, P HIV prevalence increased for older age clients (1.3%-2.0%, P = 0.159) while syphilis prevalence remained stable. HCV infections were halved among older clients in 3 years (1.7%-0.8%, P sex with men or intravenous drug use. Clients preferred LTFSWs, especially older clients (81.9%).Our results suggest that HIV and syphilis infections are increasing in older clients who prefer LTFSWs. HIV and syphilis are likely increasing in Guangxi Province through heterosexual transmission.

    Gynandromorphy, or the development of organisms with a combination of male and female morphological features, is common in Hymenoptera. The underlying mechanism is likely associated with the sex-determination system, and studying this phenomenon should lead to a deeper understanding of both embryonic development and sex determination. The reproductive capabilities of gynandromorphs (hereafter, sex mosaics) remain unclear. We studied gynandromorphy in the Malaysian ant Cardiocondyla kagutsuchi, which has sex mosaics of queens (gynandromorphs; mosaic of queens and winged male) and workers (ergatandromorphs; mosaic of worker and wingless ergatoid male). These sex mosaics were classified into seven morphological categories. Most individuals had more male than female body areas. Behavioral observations revealed that sex mosaics behave more in accordance with the “sex” of their brain than that of the reproductive organs (gaster). Relative DNA quantities showed that both female and male regions contained haploid and diploid nuclei, irrespective of their phenotypic appearance, indicating that external appearance did not reflect internal tissues. Nearly one third of the adults were sex mosaics and they were not infected with Wolbachia. Our results suggest that the production of sex mosaics in this species does not pose a substantial cost to colonies and that the underlying causes are therefore not strongly selected against.

    The concept of occupational health and safety (OHS) for commercial sex workers has rarely been investigated, perhaps because of the often informal nature of the workplace, the associated stigma, and the frequently illegal nature of the activity. We reviewed the literature on health, occupational risks, and safety among commercial sex workers. Cultural and local variations and commonalities were identified. Dimensions of OHS that emerged included legal and policing risks, risks associated with particular business settings such as streets and brothels, violence from clients, mental health risks and protective factors, alcohol and drug use, repetitive strain injuries, sexually transmissible infections, risks associated with particular classes of clients, issues associated with male and transgender commercial sex workers, and issues of risk reduction that in many cases are associated with lack of agency or control, stigma, and legal barriers. We further discuss the impact and potential of OHS interventions for commercial sex workers. The OHS of commercial sex workers covers a range of domains, some potentially modifiable by OHS programs and workplace safety interventions targeted at this population. We argue that commercial sex work should be considered as an occupation overdue for interventions to reduce workplace risks and enhance worker safety.

    In 2008, 400 males ≥18 years old who paid or traded for sex with a female sex worker (FSW) in Tijuana, Mexico, in the past 4 months completed surveys and HIV/STI testing; 30 also completed qualitative interviews. To analyze environmental sources of HIV vulnerability among male clients of FSWs in Tijuana, we used mixed methods to investigate correlates of clients who met FSWs in nightlife venues and clients' perspectives on venue-based HIV risk. Logistic regression identified micro-level correlates of meeting FSWs in nightlife venues, which were triangulated with clients' narratives regarding macro-level influences. In a multivariate model, offering increased pay for unprotected sex and binge drinking were micro-level factors that were independently associated with meeting FSWs in nightlife venues versus other places. In qualitative interviews, clients characterized nightlife venues as high risk due to the following macro-level features: social norms dictating heavy alcohol consumption; economic exploitation by establishment owners; and poor enforcement of sex work regulations in nightlife venues. Structural interventions in nightlife venues are needed to address venue-based risks. Copyright © 2011 Elsevier Ltd. All rights reserved.

    This study aimed to assess the level of condomless sex advertised online by private sex workers (PSW) in Sydney. In 2015, 750 online profiles of PSW, including 339 female, 53 male and 39 transgender PSWs, were reviewed. It was found that PSWs advertise protected anal and vaginal sex. However, 50% of female PSW advertised condomless oral sex. Age less than 25 years was associated with advertised condomless oral sex (odds ratio 1.56; 95% confidence interval 1.03-2.37; P=0.037). Online platforms are widely used for advertising, especially by female PSWs. Levels of condom use advertised reflect that of other studies of sex workers in Sydney.

    Full Text Available Objective: To describe the health practices adopted by sex workers in their daily lives. Methods: A qualitative study that took place at bars where sex workers of Maceió –AL, Brazil, work. The universe of participant subjects was integrated by 15 female sex workers, aged between 20 and 39 years, assisted by the team of a Street Clinic. The research took place between August and October 2011 and women were randomly selected. Data was collected through semi-structured interviews, which were all audio-recorded and transcribed for further analysis and interpretation. Results: Thematic analysis of the data produced and the theoretical framework of health promotion enabled the categorization of the health practices in daily life of these women, such as: prevention of sexually transmitted diseases, body care and aesthetics, physical activity, nutrition, leisure, interpersonal relationships, consumption of alcohol and others drugs, self-medication, and quest for health services. The ways they appropriate themselves of such practices are conditioned by the social vulnerability and economic and sociocultural context they are in. Conclusion: Despite the deficiencies found in the development of these practices, sex workers seek to preserve habits that improve their physical, social and mental health, as well as the pursuit of professional care and services to promote their health.

    To characterize and describe patterns of HIV, sexually transmitted infections (STI) and sexual behaviour of male clients of female sex workers (FSW). A cross-sectional study was conducted among 4821 clients of FSW from 12 districts in three states in India: Andhra Pradesh, Maharashtra and Tamil Nadu. A structured questionnaire was administered to elicit demographic characteristics and sexual behavioural patterns. Blood and urine samples were tested for HIV, syphilis and herpes simplex type 2 serology, gonococcal and chlamydial infection. The median age of clients surveyed was 30 years; 57% were married and 64% had a steady sexual partner; 61% had sex with more than one FSW and 39% had four or more sexual encounters in the past month. The prevalence of HIV ranged from 2.0% to 10.9%, syphilis ranged from 3.1% to 10.1%; gonorrhoea and chlamydia ranged between 0% and 4.5%. Clients older than 30 years [odds ratio (OR) 1.65; 95% confidence interval (CI) 1.33-2.05] and having a different mix of commercial and non-commercial partners (OR 1.56; 95% CI 1.25-1.96) had a higher volume of sex acts with FSW. Inconsistent condom use with FSW was significantly associated with older clients (OR 4.2; 95% CI 3.33-5.29), illiteracy (OR 1.39; 95% CI 1.14-1.69), age sex (OR 1.83; 95% CI 1.24-2.70) and having different FSW partners in the past month (OR 1.64; 95% CI 1.23-2.18). Clients of FSW studied here constitute a significant bridge group for HIV and other STI, because of their high volume of different sexual partners and very low consistent condom use. HIV prevention programmes need to address male clients.

    Men who have sex with men (MSM) are at increased risk for HIV infection in India, particularly those who engage in transactional sex with other men (i.e., male sex workers; MSW). Despite the need, HIV prevention efforts for Indian MSW are lacking. As in other settings, MSW in India increasingly rely on the use of mobile phones for sex work solicitation. Integrating mobile phone technology into an HIV prevention intervention for Indian MSW may mitigate some of the challenges associated with face-to face approaches, such as implementation, lack of anonymity, and time consumption, while at the same time proving to be both feasible and useful. This is a pilot randomized controlled trial to examine participant acceptability, feasibility of study procedures, and preliminary efficacy for reducing sexual risk for HIV. MSW (N = 100) were equally randomized to: (1) a behavioral HIV prevention intervention integrating in-person and mobile phone delivered HIV risk reduction counseling, and daily, personalized text or voice messages as motivating "cognitive restructuring" cues for reducing condomless anal sex (CAS); or (2) a standard of care (SOC) comparison condition. Both groups received HIV counseling and testing at baseline and 6-months, and completed ACASI-based, behavioral and psychosocial assessments at baseline, 3, and 6 months. Mixed-effects regression procedures specifying a Poisson distribution and log link with a random intercept and slope for month of follow-up was estimated to assess the intervention effect on the primary outcomes: (1) CAS acts with male clients who paid them for sex, and (2) CAS acts with male non-paying sexual partners-both outcomes assessed over the past month. The intervention was both feasible (98% retention at 6-months) and acceptable (>96% of all intervention sessions attended); all intervention participants rated the intervention as "acceptable" or "very acceptable." A reduction in the reported number of CAS acts with male clients who

    Full Text Available Abstract Background Cooperation and conflict in social insects are closely linked to the genetic structure of the colony. Kin selection theory predicts conflict over the production of males between the workers and the queen and between the workers themselves, depending on intra-colonial relatedness but also on other factors like colony efficiency, sex ratios, cost of worker reproduction and worker dominance behaviour. In most bumblebee (Bombus species the queen wins this conflict and often dominates male production. However, most studies in bumblebees have been conducted with only a few selected, mostly single mated species from temperate climate regions. Here we study the genetic colony composition of the facultative polyandrous neotropical bumblebee Bombus wilmattae, to assess the outcome of the queen-worker conflict over male production and to detect potential worker policing. Results A total of 120 males from five colonies were genotyped with up to nine microsatellite markers to infer their parentage. Four of the five colonies were queen right at point of time of male sampling, while one had an uncertain queen status. The workers clearly dominated production of males with an average of 84.9% +/- 14.3% of males being worker sons. In the two doubly mated colonies 62.5% and 96.7% of the male offspring originated from workers and both patrilines participated in male production. Inferring the mother genotypes from the male offspring, between four to eight workers participated in the production of males. Conclusions In this study we show that the workers clearly win the queen-worker conflict over male production in B. wilmattae, which sets them apart from the temperate bumblebee species studied so far. Workers clearly dominated male production in the singly as well the doubly mated colonies, with up to eight workers producing male offspring in a single colony. Moreover no monopolization of reproduction by single workers occurred.

    The HIV situation in virtually all southern African countries is a generalised epidemic. Despite the fact that almost all adult age and social groups have high HIV prevalence estimates, sex workers are disproportionally affected, with prevalence estimates higher than the general population. In a qualitative study of 61 male and female sex workers in Swaziland, we found that while poverty drove many into sex work, others reported motivations of pleasure or "sensation seeking", and freedoms from the burden of marriage as perceived benefits of sex work. We also found that penile-vaginal sex was not universal in male-female sexual encounters; and motivation by sex workers for non-condom use included intention to earn more money from unprotected sex, desire for sexual pleasure, and not having time to use condoms. Many sex workers expressed doubts over an alternative lifestyle, even if that change afforded them money to meet their daily necessities. The findings from this study suggest that treating sex workers as a homogenous group that is driven into, or maintain sex work only because of poverty may be problematic, and could hamper HIV-relevant interventions aimed at reducing their vulnerability to sexually transmitted infections.

    The existing legal framework in Russia makes sex work and related activities punishable offenses, leaving sex workers stigmatized, vulnerable to violence, and disproportionally affected by HIV and other sexually transmitted infections. In 2013, the Ministry of Justice, supported by the courts, refused registration and official recognition to the first all-Russia association of sex workers, referring to the fact that sex work is under administrative and criminal punitive bans and therefore the right of association for sex workers is unjustified. In light of international human rights standards, in particular the jurisprudence of the European Court of Human Rights, we examine in this paper whether the overall punitive legal ban on sex work in Russia is discriminatory. The government's positive obligations concerning discrimination against sex workers whose activities are consensual and between adults, and whose working conditions leave them among society's most vulnerable, should outweigh their punitive laws and policies around sex work. The scope of legal criminalization is narrow: it should apply only in exceptional cases where it is clearly justified. Copyright © 2014 Arps and Golichenko.

    Sex workers are disproportionately affected by HIV compared with the general population. Most studies of HIV risk among sex workers have focused on individual-level risk factors, with few studies assessing potential structural determinants of HIV risk. In this Article, we examine whether criminal laws around sex work are associated with HIV prevalence among female sex workers. We estimate cross-sectional, ecological regression models with data from 27 European countries on HIV prevalence among sex workers from the European Centre for Disease Control; sex-work legislation from the US State Department's Country Reports on Human Rights Practices and country-specific legal documents; the rule of law and gross-domestic product per capita, adjusted for purchasing power, from the World Bank; and the prevalence of injecting drug use among sex workers. Although data from two countries include male sex workers, the numbers are so small that the findings here essentially pertain to prevalence in female sex workers. Countries that have legalised some aspects of sex work (n=17) have significantly lower HIV prevalence among sex workers than countries that criminalise all aspects of sex work (n=10; β=-2·09, 95% CI -0·80 to -3·37; p=0·003), even after controlling for the level of economic development (β=-1·86; p=0·038) and the proportion of sex workers who are injecting drug users (-1·93; p=0·026). We found that the relation between sex work policy and HIV among sex workers might be partly moderated by the effectiveness and fairness of enforcement, suggesting legalisation of some aspects of sex work could reduce HIV among sex workers to the greatest extent in countries where enforcement is fair and effective. Our findings suggest that the legalisation of some aspects of sex work might help reduce HIV prevalence in this high-risk group, particularly in countries where the judiciary is effective and fair.

    Research has increasingly documented the important role that violence by clients and the police play in exacerbating HIV vulnerability for women in sex work. However few studies have examined violence in the intimate relationships of women in sex work, or drawn on community partnerships to explore the social dynamics involved. A community-based participatory research study was undertaken by community and academic partners leading intimate partner violence (IPV) and HIV prevention programs in Bagalkot district, Karnataka state, India. The purpose was to explore the experience and understandings of intimate partner violence and HIV/AIDS among women in sex work and their intimate partners in Bagalkot that would inform both theory and practice. A community-based, interpretive qualitative methodology was used. Data was collected between July and October 2014 through in-depth interviews with 38 participants, including 10 couples, 13 individual female sex workers, and 5 individual male intimate partners. Purposive sampling was done to maximize variation on socio-demographic characteristics. Thematic content analysis was conducted through coding and categorization for each interview question in NVivo 10.0, followed by collaborative analysis to answer the research questions. The results showed that an array of interrelated, multi-level factors underlay the widespread acceptance and perpetuation of violence and lack of condom use in participants' intimate relationships. These included individual expectations that justified violence and reflected societal gender norms, compounded by stigma, legal and economic constraints relating to sex work. The results demonstrate that structural vulnerability to IPV and HIV must be addressed not only on the individual and relationship levels to resolve relevant triggers of violence and lack of condom use, but also the societal-level to address gender norms and socio-economic constraints among women in sex work and their partners. The study

    Negotiation for condom use by female sex workers with their male clients can enhance condom use. A cross-sectional study was conducted among 1395 female sex workers; 439 from two brothels, 442 from 30 hotels, and 514 from streets of two cities in Bangladesh to determine the predictors of condom use negotiation. Consistent condom use rates in the 7 days prior to interview were reported to be 16.2%, 21.7%, and 4.5% among the brothel, hotel, and street-based female sex workers, respectively. Overall, 28.1% of female sex workers negotiated for condom use with their clients. Participation in behaviour change communication (BCC) programmes (AOR, 1.5; 95% CI, 1.2-2.0) and self-perceived risk of human immunodeficiency virus infection (AOR, 1.8 95% CI, 1.6-2.1) were positive predictors for condom negotiation. Compared to the hotel-based female sex workers, street (AOR, 0.6; 95% CI, 0.4-0.9) and brothel-based female sex workers (AOR, 0.7; 95% CI, 0.5-0.9) were less likely to negotiate for condom use. Female sex workers in Bangladesh are at high risk for sexually transmitted infection / human immunodeficiency virus infection because of low overall negotiation for condom use. Participation in BCC programmes had positive effect on condom negotiation by female sex workers, and should be strengthened in commercial sex venues.

    2015-01-01

    Commercial sex is an everyday occurrence across a range of contexts in South Africa. In this paper we turn our attention to the often-marginalised role of the buyers of sex by drawing on narrative interviews with male clients of female sex workers recruited through online advertisements in order to explore the ways in which heterosexual men construct, negotiate and perform their masculinity and sexuality through talking about their experiences of paying for sex. We highlight parallels between men's narratives of paying for sex and dominant discourses of gender and heterosexuality. We show how men draw on heteronormative sexual scripts in constructing and making sense of paid sexual encounters and how men are simultaneously able to construct and enact a particular idealised version of masculinity and male sexuality through their talk on paying for sex. Finally, we discuss how online resources could be used more extensively in future research with the male clients of sex workers.

    Sex steroids are chief regulators of gender differences in the skeleton, and male gender is one of the strongest protective factors against osteoporotic fractures. This advantage in bone strength relies mainly on greater cortical bone expansion during pubertal peak bone mass acquisition and superior skeletal maintenance during aging. During both these phases, estrogens acting via estrogen receptor-α in osteoblast lineage cells are crucial for male cortical and trabecular bone, as evident from conditional genetic mouse models, epidemiological studies, rare genetic conditions, genome-wide meta-analyses, and recent interventional trials. Genetic mouse models have also demonstrated a direct role for androgens independent of aromatization on trabecular bone via the androgen receptor in osteoblasts and osteocytes, although the target cell for their key effects on periosteal bone formation remains elusive. Low serum estradiol predicts incident fractures, but the highest risk occurs in men with additionally low T and high SHBG. Still, the possible clinical utility of serum sex steroids for fracture prediction is unknown. It is likely that sex steroid actions on male bone metabolism rely also on extraskeletal mechanisms and cross talk with other signaling pathways. We propose that estrogens influence fracture risk in aging men via direct effects on bone, whereas androgens exert an additional antifracture effect mainly via extraskeletal parameters such as muscle mass and propensity to fall. Given the demographic trends of increased longevity and consequent rise of osteoporosis, an increased understanding of how sex steroids influence male bone health remains a high research priority.

    Despite research suggesting that legal sex work is safe and that emotional risks and social stigma are of greater concern than health risks, much research on sex work has focused on health risks. Given the legalisation of sex work in Victoria, Australia, it is timely to look beyond health. Three focus groups were conducted with a total of 14 female sex workers on their experience of legal sex work, both positive and negative, and the social acceptability of their profession. Thematic analysis was used to identify the key ways that sex workers described sex work. Women saw legal sex work as safer than illegal sex work, but still not socially acceptable. However, they also described six contradictory elements of sex work, which was seen as: financially rewarding and entrapping; empowering and demeaning; increasing some opportunities while reducing others; flexible and demanding; offering both intimacy and competition; and leading to a 'double life'. While legalisation has improved the safety of sex work, stigma and discrimination persist.

    We conducted a qualitative study of male sex work in St. Petersburg Russia with a focus on social vulnerabilities, HIV-risk perception and HIV-related behaviours. In-depth interviews were conducted with individuals knowledgeable about male sex work through their profession and with male sex workers themselves. Male sex work involves a variety of exchanges, including expensive vacations, negotiated monetary amounts or simply access to food. Methods of finding clients included the Internet, social venues (e.g. gay clubs and bars) and public places (e.g. parks). Use of the Internet greatly facilitated male sex work in a variety of ways. It was used by both individuals and agencies to find clients, and appeared to be increasing. Men often reported not being professionally connected to other male sex workers and limited disclosure about their work. Many were aware of the work-related risks to personal safety, including violence and robbery by clients. Perceived risk for HIV was mostly abstract and several exceptions to condom use with clients were noted. Alcohol use was reported as moderate but alcohol was consumed frequently in association with work. These data suggest that the most salient risks for male sex workers include professional isolation, threats to personal safety, limited perceived HIV risk and sub-optimal levels of condom use.

METHOD: Cross-sectional and correlational study conducted with 73 sex workers registered at the Sex Workers´ Association of the municipality of Picos -PI, Brazil. Data were collected in September and October 2010 using a questionnaire to obtain sociodemographic information and the participants´ background in the sex industry. Ethical aspects were observed. RESULTS: There was no significant association between most of the sociodemographic variables and background in the sex industry and condom use by male partners or clients. However, there was a significant association with years in the sex industry (p = 0.029. Sex workers who had been in the industry for the longest used condoms for protection against sexually transmitted diseases. CONCLUSION: It is essential to create health promotion strategies that observe the real-life experiences of sex workers.

    Worldwide, transgender women who engage in sex work have a disproportionate risk for HIV compared with natal male and female sex workers. We reviewed recent epidemiological research on HIV in transgender women and show that transgender women sex workers (TSW) face unique structural, interpersonal, and individual vulnerabilities that contribute to risk for HIV. Only six studies of evidence-based prevention interventions were identified, none of which focused exclusively on TSW. We developed a deterministic model based on findings related to HIV risks and interventions. The model examines HIV prevention approaches in TSW in two settings (Lima, Peru and San Francisco, CA, USA) to identify which interventions would probably achieve the UN goal of 50% reduction in HIV incidence in 10 years. A combination of interventions that achieves small changes in behaviour and low coverage of biomedical interventions was promising in both settings, suggesting that the expansion of prevention services in TSW would be highly effective. However, this expansion needs appropriate sustainable interventions to tackle the upstream drivers of HIV risk and successfully reach this population. Case studies of six countries show context-specific issues that should inform development and implementation of key interventions across heterogeneous settings. We summarise the evidence and knowledge gaps that affect the HIV epidemic in TSW, and propose a research agenda to improve HIV services and policies for this population. PMID:25059941

    While the literature on male sex work has increased significantly over the past decade, few studies examine the influence of relational dynamics in the lives of those engaged in male sex work. This qualitative study, conducted with a sample of male street sex workers in Sydney, Australia, explores how relationships color their involvement with sex work. The findings reveal the complexity of their relationships and how their interactions with others shape their engagement in sex work. The data also offer insight into how exit pathways are influenced by money and relationships that occur within this particular male sex work setting. Implications for health policy and intervention are considered.

    Sex work is a criminal offence, virtually throughout Africa. This criminalisation and the intense stigma attached to the profession shapes interactions between sex workers and their clients, family, fellow community members, and societal structures such as the police and social services. We explore the impact of violence and related human rights abuses on the lives of sex workers, and how they have responded to these conditions, as individuals and within small collectives. These analyses are based on data from 55 in-depth interviews and 12 focus group discussions with female, male and transgender sex workers in Kenya, South Africa, Uganda and Zimbabwe. Data were collected by sex worker outreach workers trained to conduct qualitative research among their peers. In describing their experiences of unlawful arrests and detention, violence, extortion, vilification and exclusions, participants present a picture of profound exploitation and repeated human rights violations. This situation has had an extreme impact on the physical, mental and social wellbeing of this population. Overall, the article details the multiple effects of sex work criminalisation on the everyday lives of sex workers and on their social interactions and relationships. Underlying their stories, however, are narratives of resilience and resistance. Sex workers in our study draw on their own individual survival strategies and informal forms of support and very occasionally opt to seek recourse through formal channels. They generally recognize the benefits of unified actions in assisting them to counter risks in their environment and mobilise against human rights violations, but note how the fluctuant and stigmatised nature of their profession often undermines collective action. While criminal laws urgently need reform, supporting sex work self-organisation and community-building are key interim strategies for safeguarding sex workers' human rights and improving health outcomes in these communities.

We also described the characteristics of the adolescents who reported inconsistent condom use with FSWs.This is a cross-sectional study (response rate: 73% of 300 heterosexually active male adolescents of 16 to 19 years attending a national STI clinic in Singapore between 2009 and 2014. We assessed the ecological factors (individual, parental, peer, school and medial influences and sexual risk behaviors using a self-reported questionnaire. Poisson regression was used to obtain the adjusted prevalence ratios (aPR and confidence intervals (CI.The proportion of heterosexual male adolescents who had ever had sex with FSWs was 39%. Multivariate analysis showed that significant factors associated with ever having had sex with FSWs were sex initiation before 16 years old (aPR 1.79 CI: 1.30-2.46, never had a sexually active girlfriend (aPR 1.75 CI 1.28-2.38, reported lower self-esteem score (aPR 0.96 CI: 0.93-0.98, higher rebelliousness score (aPR 1.03 CI: 1.00-1.07 and more frequent viewing of pornography (aPR 1.47 CI: 1.04-2.09. Lifetime inconsistent condom use with FSWs was 30%.A significant proportion of heterosexual male adolescents attending the public STI clinic had ever had sex with FSWs. A targeted intervention that addresses different levels of influence to this behavior is needed. This is even more so because a considerable proportion of adolescents reported inconsistent condom use with FSWs, who may serve as a bridge of STI transmission to the community. National surveys on adolescent health should include the assessment of frequency of commercial sex visits and condom use with FSWs for long-term monitoring and surveillance.

  9. Senegal: where "card-carrying" sex workers are legal.

    An estimated 1.5% of Senegal's 5 million adult population is HIV-seropositive, with 3000 people having already died of AIDS-related illnesses. Although 75% of those with AIDS are men, women comprise the majority of people infected with HIV. This latter phenomenon is most likely the result of men having become infected before women because of the former's greater degree of travel relative to women. Infection with HIV-2 accounts for 70% of those with HIV, but for only 30% of AIDS cases. HIV-1 is, however, becoming a growing problem since it seems to be transmitted more easily and develop into AIDS more quickly. 15% of prostitutes in Senegal are HIV-seropositive compared to more than 50% of comparable subgroups in most African countries. Experts cannot say for sure why Senegal has a comparatively low rate of HIV, but several factors have been posited as explanations. The comparatively low rate of infection could be related to the long distance between Senegal and the HIV-1 epicenters of east and central Africa, the ability of HIV-2 infection to help the body fight off HIV-1, the strong Islamic influence which has made male circumcision universal thus reducing the risk of contracting HIV, the provision of AIDS awareness and prevention early in the epidemic, and the government's permissive approach to commercial sex. This latter factor is probably the most important related to the current status of HIV/AIDS in Senegal. It has been legal since 1966 to sell sex as long as the sex worker is registered, over 21 years old, has a regular medical check-up, and can present an up-to-date medical report card to the police upon request. This approach was established by then-president Senghor to reduce the incidence and prevalence of sexually transmitted diseases (STD). Registered sex workers since 1986 have been tested for HIV, advised on how to avoid infection, and given free condoms. In anonymous questionnaires, 70-75% of all Dakar's official sex workers reported always using

    This study aimed to build formative knowledge regarding HIV risks in female migrant sex workers in Moscow, focusing on gender and power. This was a collaborative ethnographic study, informed by the theory of gender and power, in which researchers conducted minimally structured interviews with 24 female sex workers who were migrants to Moscow and who provided sexual services to male migrant laborers. Overall, the female migrant sex workers engaged in HIV risk behaviors and practiced inadequate HIV protection with their clients. These behaviors were shaped by gender and power factors in the realms of labor, behavior, and cathexis. In the labor realm, because some female migrants were unable to earn enough money to support their families, they were pushed or pulled into sex work providing service to male migrants. In the behavior realm, many female migrant sex workers were intimidated by their male clients, feared violence, and lacked access to women's health care and prevention. In the cathexis realm, many had a sense of shame, social isolation, emotional distress, and lacked basic HIV knowledge and prevention skills. To prevent HIV transmission requires addressing the gender and power factors that shape HIV/AIDS risks among female migrant sex workers through multilevel intervention strategies.

    Increased uptake of HIV testing by men in sub-Saharan Africa is essential for the success of combination prevention. Self-testing is an emerging approach with high acceptability, but little evidence exists on the best strategies for test distribution. We assessed an approach of providing multiple self-tests to women at high risk of HIV acquisition to promote partner HIV testing and to facilitate safer sexual decision making. In this cohort study, HIV-negative women aged 18-39 years were recruited at two sites in Kisumu, Kenya: a health facility with antenatal and post-partum clinics and a drop-in centre for female sex workers. Participants gave informed consent and were instructed on use of oral fluid based rapid HIV tests. Participants enrolled at the health facility received three self-tests and those at the drop-in centre received five self-tests. Structured interviews were conducted with participants at enrolment and over 3 months to determine how self-tests were used. Outcomes included the number of self-tests distributed by participants, the proportion of participants whose sexual partners used a self-test, couples testing, and sexual behaviour after self-testing. Between Jan 14, 2015, and March 13, 2015, 280 participants were enrolled (61 in antenatal care, 117 in post-partum care, and 102 female sex workers); follow-up interviews were completed for 265 (96%). Most participants with primary sexual partners distributed self-tests to partners: 53 (91%) of 58 participants in antenatal care, 91 (86%) of 106 in post-partum care, and 64 (75%) of 85 female sex workers. 82 (81%) of 101 female sex workers distributed more than one self-test to commercial sex clients. Among self-tests distributed to and used by primary sexual partners of participants, couples testing occurred in 27 (51%) of 53 in antenatal care, 62 (68%) of 91 from post-partum care, and 53 (83%) of 64 female sex workers. Among tests received by primary and non-primary sexual partners, two (4%) of 53

    In recent years, Europe has witnessed a rise in the number of migrant sex workers, in part because of increased mobility for citizens of European Union member states. However, migrant sex workers find themselves in a highly vulnerable position in regard to having their rights respected and accessing HIV prevention services. In this article, based on a presentation at AIDS 2010, Licia Brussa and Veronica Munk outline the current situation of migrant sex workers in Europe and the steps that need to be taken to ensure that their rights are respected.

  18. Aging and sex hormones in males

    Science.gov (United States)

    Decaroli, Maria Chiara

    2017-01-01

    ABSTRACT Several large cohort studies have disclosed the trajectories of sex steroids changes overtime in men and their clinical significance. In men the slow, physiological decline of serum testosterone (T) with advancing age overlaps with the clinical condition of overt, pathological hypogonadism. In addition, the increasing number of comorbidities, together with the high prevalence of chronic diseases, all further contribute to the decrease of serum T concentrations in the aging male. For all these reasons both the diagnosis of late-onset hypogonadism (LOH) in men and the decision about starting or not T replacement treatment remain challenging. At present, the biochemical finding of T deficiency alone is not sufficient for diagnosing hypogonadism in older men. Coupling hypogonadal symptoms with documented low serum T represents the best strategy to refine the diagnosis of hypogonadism in older men and to avoid unnecessary treatments. PMID:27831823

    Night shift work has been associated with an increased risk for breast and prostate cancer. The effect of circadian disruption on sex steroid production is a possible underlying mechanism, underinvestigated in humans. We have assessed daily rhythms of sex hormones and melatonin in night and day shift workers of both sexes. We recruited 75 night and 42 day workers, ages 22 to 64 years, in different working settings. Participants collected urine samples from all voids over 24 hours on a working day. Urinary concentrations of 16 sex steroid hormones and metabolites (estrogens, progestagens, and androgens) and 6-sulfatoxymelatonin were measured in all samples. Mean levels and peak time of total and individual metabolite production were compared between night and day workers. Night workers had higher levels of total progestagens [geometric mean ratio (GMR) 1.65; 95% confidence intervals (CI), 1.17-2.32] and androgens (GMR: 1.44; 95% CI, 1.03-2.00), compared with day workers, after adjusting for potential confounders. The increased sex hormone levels among night shift workers were not related to the observed suppression of 6-sulfatoxymelatonin. Peak time of androgens was significantly later among night workers, compared with day workers (testosterone: 12:14 hours; 10:06-14:48 vs. 08:35 hours; 06:52-10:46). We found increased levels of progestagens and androgens as well as delayed peak androgen production in night shift workers compared with day workers. The increase and mistiming of sex hormone production may explain part of the increased risk for hormone-related cancers observed in night shift workers. ©2015 American Association for Cancer Research.

    The women, men, and transgender people who sell sex globally have disproportionate risks and burdens of HIV in countries of low, middle, and high income, and in concentrated and generalised epidemic contexts. The greatest HIV burdens continue to be in African female sex workers. Worldwide, sex workers still face reduced access to needed HIV prevention, treatment, and care services. Legal environments, policies, police practices, absence of funding for research and HIV programmes, human rights violations, and stigma and discrimination continue to challenge sex workers' abilities to protect themselves, their families, and their sexual partners from HIV. These realities must change to realise the benefits of advances in HIV prevention and treatment and to achieve global control of the HIV pandemic. Effective combination prevention and treatment approaches are feasible, can be tailored for cultural competence, can be cost-saving, and can help to address the unmet needs of sex workers and their communities in ways that uphold their human rights. To address HIV in sex workers will need sustained community engagement and empowerment, continued research, political will, structural and policy reform, and innovative programmes. But such actions can and must be achieved for sex worker communities everywhere. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To measure prevalence of HIV and syphilis and describe characteristics of sex work among female sex workers (FSWs) in Hargeisa, Somaliland, Somalia. A cross-sectional survey recruited 237 FSWs using respondent-driven sampling (RDS). A face-to-face, structured interview using handheld-assisted personal interviewing (HAPI) on personal digital assistants (PDAs) was completed and blood collected for serological testing. FSWs 15-19 years old accounted for 6.9% of the population; 20-24 year-old constituted an additional 18.0%. The majority (86.6%) never attended school. International (59.0%) and interzonal (10.7%) migration was common. Most (95.7%) reported no other source of income; 13.8% had five or more clients in the last 7 days. A minority (38.4%) had heard of STIs, even fewer (6.9%) held no misconceptions about HIV. Only 24% of FSW reported using a condom at last transactional sex, and 4% reported ever been tested for HIV. HIV prevalence was 5.2% and syphilis prevalence was 3.1%. Sex work in Hargeisa, Somaliland, Somalia, is characterized by high numbers of sexual acts and extremely low knowledge of HIV. This study illustrates the need for targeted HIV prevention interventions focusing on HIV testing, risk-reduction awareness raising, and review of condom availability and distribution mechanisms among FSWs and males engaging with FSWs.

  4. Vulnerability on the streets: female sex workers and HIV risk.

    Pyett, P M; Warr, D J

    1997-10-01

    In-depth interviews were conducted with 24 purposively selected female sex workers who were perceived to be vulnerable to risks associated with their lifestyle and occupation. Brothel workers were found to be considerably less exposed to risk than the women working on the streets. Client resistance was the major obstacle to women maintaining safe sex practices. Physical threats and coercion from clients, the absence of legal protection for street workers, the workers' extreme social isolation and lack of community support added to the difficulties experienced by women in their attempts to insist on condoms for all sex services. Youth, homelessness and heavy drug use had contributed to women being at times even more vulnerable because they had less capacity to manage situations of potential violence or STD risk. Whether through sex work or in their private relationships, HIV remains a risk for some of these women. This study highlights the dangers associated with illegal sex work. While decriminalization of prostitution would reduce some of the dangers to which women were exposed and increase women's capacity to insist on safe sex practices, it is also important for community education programmes to address men's failure to accept responsibility for condom use when seeking the services of sex workers.

    The Chinese Government periodically enforces anti-prostitution laws through regular police presence in red light districts and through the arrests of brothel managers and sex workers. One of the most intense crackdowns on prostitution occurred throughout China in 2010. Using the 'structure-agency' framework and ethnographic approach, this paper examines the influence of the 2010 government anti-prostitution crackdown on female sex workers (FSWs). We observed 10 red light districts (6 cities and 2 counties) and interviewed 107 FSWs, 26 managers and 37 outreach workers working with FSWs. The findings describe variations in police practices and diverse strategies adopted by FSWs in response to police actions. The strategies include: soliciting sex outside of establishments in less visible channels, increasing the mobility and flexibility of sex work, changing sexual practices, sharing knowledge of how to identify policemen disguised as male clients and building personal relationships with local police. Our study suggests that, rather than disappearing as a result of crackdowns, the terms and content of sex work changed as a result of the FSWs' responses to police practices. Some of these responses potentially increased the health risks associated with sex work, but others laid the foundation for an effective response to police practices.

    The experiences of the commercial sex workers as they fulfill the role of being a parent, have rarely been reported. Considering their socioeconomic background, profession and work pattern, the women are bound to face major challenges. To describe child bearing, family support, dietary practices and various placement options for raising children. A cross-sectional descriptive study of brothel-based commercial sex workers. X2 test, Fisher's Exact test. Some commercial sex workers continued pregnancy with the hope of security and support, while others were compelled to do so, as they report late for medical termination of pregnancy. A group of sex workers (Devdasis) received support during pregnancy, delivery, puerperium and child-rearing. The role and responsibilities of raising the child, depended upon the kind of family support available to the mothers. Being a single parent, stigma of the profession, odd working hours and variable family support were major challenges, while the fact that the women were earning, availability of rehabilitation centers, the homogeneous groups within the brothels, supportive peers and local non governmental organizations were factors which helped them in the process of raising their children. Day care centers and night shelters should be opened up in the red light area where the children can be looked after, during the working hours. The sex workers should be educated about weaning and nutrition. The role of peer workers and NGOs was very important in helping the women raise their children.

  10. Adolescent female sex workers: invisibility, violence and HIV.

    Science.gov (United States)

    Silverman, Jay G

    2011-05-01

    A large number of female sex workers are children. Multiple studies demonstrate that up to 40% of women in prostitution started this work prior to age 18. In studies across India, Nepal, Thailand and Canada, young age at entry to sex work has been found to heighten vulnerability to physical and sexual violence victimisation in the context of prostitution, and relates to a two to fourfold increase in HIV infection. Although HIV risk reduction among adult female sex workers has been a major focus of HIV prevention efforts across the globe, no public health interventions, to date, have addressed the increased hazards and HIV risk faced by adolescent female sex workers. Beyond the structural barriers that limit access to this vulnerable group, historical tensions between HIV prevention and child protection agencies must be overcome in order to develop effective strategies to address this large scale yet little recognised human rights and HIV-related crisis.

    Sex work is rarely an occupation of choice for Iranian women and is often described as a last resort. While several factors play a role in creating an environment where individuals become involved in sex work, female sex workers' experiences regarding entry into sex work in Iran are poorly understood. In this qualitative study, a convenience sample of 24 participants was recruited from a drop-in centre for vulnerable women in Kerman, Iran. Through in-depth interviews, participants were asked about their personal lived experiences of initiating sex work. Grounded theory was used to analyse findings from this research. We learned that major factors impacting on women's initiation into sex work circulated around their vulnerability and chronic poverty. Participants continued to sell sex due to their limited opportunities, drug dependence and financial needs. Improving sex workers' economic status could be a vital intervention in providing vulnerable women with options other than sex work. Female sex workers should be provided with government support and educational programmes delivered through special centres. Despite the illegal status of their work, sex workers' needs should be recognised across all aspects of policy and legislation.

  12. Combating human trafficking in the sex trade: can sex workers do it better?

    2014-12-01

    The dominant anti-trafficking paradigm conflates trafficking and sex work, denying evidence that most sex workers choose their profession and justifying police actions that disrupt communities, drive sex workers underground and increase vulnerability. We review an alternative response to combating human trafficking and child prostitution in the sex trade, the self-regulatory board (SRB) developed by Durbar Mahila Samanwaya Committee (DMSC, Sonagachi). DMSC-led interventions to remove minors and unwilling women from sex work account for over 80% of successful 'rescues' reported in West Bengal. From 2009 through 2011, 2195 women and girls were screened by SRBs: 170 (7.7%) minors and 45 (2.1%) unwilling adult women were assisted and followed up. The remaining 90.2% received counselling, health care and the option to join savings schemes and other community programmes designed to reduce sex worker vulnerability. Between 1992 and 2011 the proportion of minors in sex work in Sonagachi declined from 25 to 2%. With its universal surveillance of sex workers entering the profession, attention to rapid and confidential intervention and case management, and primary prevention of trafficking-including microcredit and educational programmes for children of sex workers-the SRB approach stands as a new model of success in anti-trafficking work. © The Author 2013.

    Lutnick, Alexandra; Cohan, Deborah

    2009-11-01

    Sex work is a criminal offence in San Francisco, USA, and sex work advocates have so far unsuccessfully campaigned for decriminalizing it. Some groups argue that the decriminalization movement does not represent the voices of marginalized sex workers. Using qualitative and quantitative data from the Sex Worker Environmental Assessment Team Study, we investigated the perspectives and experiences of a range of female sex workers regarding the legal status of sex work and the impact of criminal law on their work experiences. Forty women were enrolled in the qualitative phase in 2004 and 247 women in the quantitative phase in 2006-07. Overall, the women in this study seemed to prefer a hybrid of legalization and decriminalization. The majority voiced a preference for removing statutes that criminalize sex work in order to facilitate a social and political environment where they had legal rights and could seek help when they were victims of violence. Advocacy groups need to explore the compromises sex workers are willing to make to ensure safe working conditions and the same legal protections afforded to other workers, and with those who are most marginalized to better understand their immediate needs and how these can be met through decriminalization.

    While the stigma surrounding sex work is both well documented and easily recognised, few studies examine stigma in this context from the perspective of the sex workers themselves. In this article we report on a study using a modified grounded theory approach to analyse a series of semi-structured interviews with 49 female sex workers in Hong Kong, in order to examine the ways in which this group experiences and negotiates the stigma which arises from their employment in the sex industry. Sex workers in Hong Kong were subject to various stigmatising forces in their daily lives in their interactions with the public, the police and their families. These processes could have a negative impact on the sex workers' health, both through obvious manifestations such as physical or verbal abuse and through more subtle processes such as those which generated or perpetuated vulnerability and those which compelled the sex workers to conceal their identities and withdraw themselves from social networks. These findings are situated in the context of broader research surrounding sex work, drawing attention to the consequences of stigma on health and their interaction with health-service providers, before briefly discussing possible means of overcoming stigma-related barriers to providing adequate healthcare for this marginalised group. © 2010 The Authors.

    Getz, Sandra K.; Herman, Jeanne B.

    This study tests whether or not there are sex differences in judgments of the success of various male and female lifestyles, and if so, what differential standards are applied to males and females. The most interesting result of this study is that college men and women use the same standards to judge the success of male lifestyles but different…

    There are several studies that showed the high prevalence of high-risk sexual behaviors among youths, but little is known how significant the proportion of higher risk sex is when the male and female youths are compared. A meta-analysis was done using 26 countries' Demographic and Health Survey data from and outside Africa to make comparisons of higher risk sex among the most vulnerable group of male and female youths. Random effects analytic model was applied and the pooled odds ratios were determined using Mantel-Haenszel statistical method. In this meta-analysis, 19,148 male and 65,094 female youths who reported to have sexual intercourse in a 12-month period were included. The overall OR demonstrated that higher risk sex was ten times more prevalent in male youths than in female youths. The practice of higher risk sex by male youths aged 15-19 years was more than 27-fold higher than that of their female counterparts. Similarly, male youths in urban areas, belonged to a family with middle to highest wealth index, and educated to secondary and above were more than ninefold, eightfold and sixfold at risk of practicing higher risk sex than their female counterparts, respectively. In conclusion, this meta-analysis demonstrated that the practice of risky sexual intercourse by male youths was incomparably higher than female youths. Future risky sex protective interventions should be tailored to secondary and above educated male youths in urban areas.

    HIV incidence is increasing in Central Asia, where migrant workers experience risks for acquiring sexually transmitted HIV. As a social and structural factor that may influence perceptions and behavior, we examine how Islam shapes HIV risk and protection. Phenomenological qualitative interviews examine religion and contexts of HIV risk among 48 male Central Asian migrant workers residing in Almaty, Kazakhstan. Men described nonvaginal sex, alcohol use, premarital sex, and extramarital sex as forbidden or frowned upon. Religious networks were unlikely to discuss HIV risks, and some men viewed religious affiliation or practices as protective. Marital practices including neke (religious marriage), polygyny, and bride kidnapping may be linked to risk. Findings suggest adhering to Islamic ideals may be protective for some men, but for others, assumptions of protection may enhance risk. HIV prevention strategies among Central Asian migrants may be strengthened by attention to religious and cultural understandings of risk and protection.

    Full Text Available In Hymenoptera, homozygosity at the sex locus results in the production of diploid males. In social species, these pose a double burden by having low fitness and drawing resources normally spent for increasing the work force of a colony. Yet, diploid males are of academic interest as they can elucidate effects of ploidy (normal males are haploid, whereas the female castes, the queens and workers, are diploid on morphology and life history. Herein we investigated expression levels of ten caste-related genes in the stingless bee Melipona quadrifasciata, comparing newly emerged and 5-day-old diploid males with haploid males, queens and workers. In diploid males, transcript levels for dunce and paramyosin were increased during the first five days of adult life, while those for diacylglycerol kinase and the transcriptional co-repressor groucho diminished. Two general trends were apparent, (i gene expression patterns in diploid males were overall more similar to haploid ones and workers than to queens, and (ii in queens and workers, more genes were up-regulated after emergence until day five, whereas in diploid and especially so in haploid males more genes were down-regulated. This difference between the sexes may be related to longevity, which is much longer in females than in males.

    Spanger, Marlene

    A number of studies demonstrate that some migrants sell sexual services as a survival strategy that allows them to provide for their children and for the family they have left behind. The entanglement of familial intimate relationships and the organisation of female sex work have been largely...... neglected in the literature on sex for sale. This chapter therefore examines how female migrants selling sexual services organise their mothering and the various ways in which their identities as single mothers, migrants, and sex workers intersect. Drawing on the literature of transnational motherhood...

    Despite their large numbers, and important role in the HIV epidemic in India, male clients of female sex workers (FSWs) are a difficult to reach population and little is known about their sexual behaviors. Using data from an integrated behavioral and biological assessment of 684 clients in Bangalore in 2012, we examined factors associated with their reports of having sex with three or more different female sex workers in the last month, and anal sex with sex workers. We included sociodemographic and sexual behavior factors and, for the first time in client studies in India, included data on the use of pornography and sexual enhancement products (SEPs) such as pills, oils, and sprays, in our multivariable analyses of client risk. Seventy-eight percent of clients had seen pornographic material and 8% reported ever having used SEPs. The profiles of men practicing the two risk behaviors examined were quite different. Travel in the past year, drunkenness in the past month, young age at first commercial sex, non-use of condoms at last sex, and finding sex workers in public places (but not use of pornography and SEPs) were independently associated with multiple partnering. Sex with a man or transsexual, being a white collar worker, seeking out FSWs at home, pornography and SEP use, and condom use at last FSW sex, were all independently associated with anal sex with an FSW. More research is needed to better understand the links between pornography and SEPs, and HIV risk behaviors, and HIV prevention programs need to be cognizant of the importance of ensuring that condom use is adequately promoted and supported in the context of anal sex in female sex worker-client interactions.

    2015-01-01

    Full Text Available Background: Male migrants act as a bridge for transmitting infection from core risk groups to general population and hence this group becomes essential for the HIV control program. Migrant workers constitute a large proportion of workforce in India and HIV/AIDS epidemic in them would cause huge economic losses. Objectives: The aim of this study was to ascertain the HIV-risk behavior among male migrant factory workers. Materials and Methods: This was a cross-sectional facility based survey conducted in 2011. Male migrant workers aged ≥18 years, who were born outside Haryana, who had moved to current location after 15 years of age, who had worked in the current factory for at least one year, who were willing to participate and able to give valid consent were eligible. A consecutive sampling was done. Descriptive, bivariate and multiple logistic regression analyses were done. Results: A total of 755 male subjects completed the interview. About 21.5% had experienced non-spousal sexual intercourse in last one year. Nearly 60% did not use a condom at the last non-spousal sex. Factors associated with recent non-spousal sex were being unmarried, younger age at migration, recent migration to Haryana, greater number of places migrated and lesser total duration of migration and those associated with non-use of condom at the last non-spousal sex were older age, lower education, lesser number of places migrated and lower level of HIV/AIDS knowledge. Conclusion: Unprotected, recent non-spousal sex was common among male migrants, which could increase their HIV/AIDS vulnerability.

    Commercial sex work is frequent among male-to-female transvestites, transsexuals and transgenders in Argentina, leading to high susceptibility to HIV, HBV, and HCV among other sexually transmitted infections. In a global context of scarce data on the trans sex workers population, this study was aimed to study the genomic characterization of these viruses. Plasma presence of HIV, HBV, and HCV genomic material was evaluated in samples from 273 trans sex workers. Genomic sequences of HIV-gag, pol, and vif-vpu genes, HBV-S gene, and HCV-5'UT and NS5B genes were obtained. Molecular characterization involved phylogenetic analysis and several in silico tools. Resistance-associated mutations in HIV and HBV pol genes were also analyzed. The HIV genomic characterization in 62 trans sex workers samples showed that 54.8% of the isolates corresponded to BF intersubtype recombinants, and 38.7% to subtype B. The remaining were classified as subtypes C (4.8%) and A (1.6%). HBV and HCV co-infection prevalence among HIV positive trans sex workers yielded rates of 3.2% and 6.5% respectively. Drug resistance-associated mutations were found in 12/62 (19%) HIV pol sequences, but none among HBV. Based on phylogenetic relationships, HIV isolates characterized as subtypes BF and B appeared intermingled with those from other high-risk groups. Despite trans sex workers declared not to have received antiviral treatment, complex drug resistance-associated mutation patterns were found in several HIV isolates. Planned prevention, screening, and treatment are needed to reduce further transmission and morbidity. © 2013 Wiley Periodicals, Inc.

    The anal sex among heterosexual couples is on the rise as reported in many scientific studies. Considering that unprotected anal sex has higher risk of human immunodeficiency virus (HIV) transmission than the vaginal sex, we undertook a study to understand the anal sex practices among Female Sex Workers (FSW). The study was conducted among FSW attending 11 randomly selected sexually transmitted infection (STI) clinics in Bill and Melinda Gates supported targeted interventions in Andhra Pradesh. A structured questionnaire was administered to the 555 FSW attending these clinics by project clinic counselors. Informed consent was obtained from all the study participants. Engaging in anal sex was self reported by 22% of sex workers, though demand from clients was reported to be much higher (40%). The reasons for anal sex practices included more money (61%), clout/influence of the client (45%), risk of losing client (27%), and forced sex (1.2%). Factors associated with anal sex were higher number of clients, higher duration of sex work, higher income, and older age group. Associated risks perceived by FSW were bleeding and injury to anal canal (98%) while only 28% associated it with higher HIV transmission risk. Reported Condom and lubricant use was about 88% and 39% respectively. The study shows that there is frequent anal sex, inconsistent condom and infrequent lubricant usage, economic and physical coercion, and low awareness of STI/HIV transmission risk among FSW, which have serious implications for HIV prevention programmes. There is a need to focus on anal sex education and use of lubricants along with condoms during anal sex in FSW-targeted interventions in AP.

    Literature speculating on the fetal origins of later life morbidity often invokes the "damaged cohort" theory, i.e., that maternal responses to exogenous shocks induce "stress reactivity" in fetuses and thereby shorten the lifespan of males in utero during stressful times. A rival, or "culled cohort," theory posits that exogenous shocks to gravid females induce spontaneous abortions of frail male fetuses, leaving relatively hardy survivors who enjoy, on average, lifespans longer than males in less stressed birth cohorts. A recent test based on archival data from Sweden supported the culled cohort theory. Several characteristics of the Swedish data, however, raise questions regarding the external validity of the findings. We repeat the test with data from Denmark, Iceland, and England and Wales. We use time-series methods that control for trends, seasonal cycles, and other forms of autocorrelation that could confound the test. None of the results supports the "damaged cohort" theory. Consistent with the Swedish findings and with evolutionary theory, we find support in Iceland and England and Wales for the "culled cohort" theory. We discuss the implications of our findings for basic research as well as for public health.

    HIV prevalence is disproportionately high among female sex workers compared to the general population. Many African countries lack useful data on the size of female sex worker populations to inform national HIV programmes. A female sex worker size estimation exercise using three different venue-based methodologies was conducted among female sex workers in all provinces of Rwanda in August 2010. The female sex worker national population size was estimated using capture-recapture and enumeration methods, and the multiplier method was used to estimate the size of the female sex worker population in Kigali. A structured questionnaire was also used to supplement the data. The estimated number of female sex workers by the capture-recapture method was 3205 (95% confidence interval: 2998-3412). The female sex worker size was estimated at 3348 using the enumeration method. In Kigali, the female sex worker size was estimated at 2253 (95% confidence interval: 1916-2524) using the multiplier method. Nearly 80% of all female sex workers in Rwanda were found to be based in the capital, Kigali. This study provided a first-time estimate of the female sex worker population size in Rwanda using capture-recapture, enumeration, and multiplier methods. The capture-recapture and enumeration methods provided similar estimates of female sex worker in Rwanda. Combination of such size estimation methods is feasible and productive in low-resource settings and should be considered vital to inform national HIV programmes. © The Author(s) 2015.

    Full Text Available BACKGROUND: It seems generally accepted that targeted interventions in India have been successful in raising condom use between female sex workers (FSWs and their clients. Data from clients of FSWs have been under-utilised to analyse the risk environments and vulnerability of both partners. METHODS: The 2009 Integrated Biological and Behavioural Assessment survey sampled clients of FSWs at hotspots in Andhra Pradesh, Maharashtra and Tamil Nadu (n=5040. The risk profile of clients in terms of sexual networking and condom use are compared across usual pick-up place. We used propensity score matching (PSM to estimate the average treatment effect on treated (ATT of intervention messages on clients' consistent condom use with FSW. RESULTS: Clients of the more hidden sex workers who solicit from home or via phone or agents had more extensive sexual networks, reporting casual female partners as well as anal intercourse with male partners and FSW. Clients of brothel-based sex workers, who were the least educated, reported the fewest number/categories of partners, least anal sex, and lowest condom use (41%. Consistent condom use varied widely by state: 65% in Andhra Pradesh, 36% in Maharashtra and 29% in Tamil Nadu. Exposure to intervention messages on sexually transmitted infections was lowest among men frequenting brothels (58%, and highest among men soliciting less visible sex workers (70%. Exposure had significant impact on consistent condom use, including among clients of home-based sex workers (ATT 21%; p=0.001 and among men soliciting other more hidden FSW (ATT 17%; p=0.001. In Tamil Nadu no impact could be demonstrated. CONCLUSION: Commercial sex happens between two partners and both need to be, and can be, reached by intervention messages. Commercial sex is still largely unprotected and as the sex industry gets more diffuse a greater focus on reaching clients of sex workers seems important given their extensive sexual networks.

    Full Text Available Reproduction in sexually dimorphic animals relies on successful gamete production, executed by the germline and aided by somatic support cells. Somatic sex identity in Drosophila is instructed by sex-specific isoforms of the DMRT1 ortholog Doublesex (Dsx. Female-specific expression of Sex-lethal (Sxl causes alternative splicing of transformer (tra to the female isoform traF. In turn, TraF alternatively splices dsx to the female isoform dsxF. Loss of the transcriptional repressor Chinmo in male somatic stem cells (CySCs of the testis causes them to "feminize", resembling female somatic stem cells in the ovary. This somatic sex transformation causes a collapse of germline differentiation and male infertility. We demonstrate this feminization occurs by transcriptional and post-transcriptional regulation of traF. We find that chinmo-deficient CySCs upregulate tra mRNA as well as transcripts encoding tra-splice factors Virilizer (Vir and Female lethal (2d (Fl(2d. traF splicing in chinmo-deficient CySCs leads to the production of DsxF at the expense of the male isoform DsxM, and both TraF and DsxF are required for CySC sex transformation. Surprisingly, CySC feminization upon loss of chinmo does not require Sxl but does require Vir and Fl(2d. Consistent with this, we show that both Vir and Fl(2d are required for tra alternative splicing in the female somatic gonad. Our work reveals the need for transcriptional regulation of tra in adult male stem cells and highlights a previously unobserved Sxl-independent mechanism of traF production in vivo. In sum, transcriptional control of the sex determination hierarchy by Chinmo is critical for sex maintenance in sexually dimorphic tissues and is vital in the preservation of fertility.

    2008-01-01

    The fungal cultivars of fungus-growing ants are vertically transmitted by queens but not males. Selection would therefore favor cultivars that bias the ants' sex ratio towards gynes, beyond the gyne bias that is optimal for workers and queens. We measured sex allocation in 190 colonies of six...... sympatric fungus-growing ant species. As predicted from relatedness, female bias was greater in four singly mated Sericomyrmex and Trachymyrmex species than in two multiply mated Acromyrmex species. Colonies tended to raise mainly a single sex, which could be partly explained by variation in queen number......, colony fecundity, and fungal garden volume for Acromyrmex and Sericomyrmex, but not for Trachymyrmex. Year of collection, worker number and mating frequency of Acromyrmex queens did not affect the colony sex ratios. We used a novel sensitivity analysis to compare the population sex allocation ratios...

    Global literature on female sex workers suggests that being in an intimate relationship is associated with barriers to practising safe sex behaviours. Condom use within intimate relationships is often seen as a sign of infidelity and fosters mistrust which could affect longevity, trust and intimacy within partnerships. Using qualitative data from Devadasi sex workers and their intimate male partners in Bagalkot District, Karnataka, India, we examined both partners' perspectives to understand the quality and dynamics of these relationships and the factors that influence condom use in intimate relationships. Our thematic analysis of individual interviews conducted in May 2011 with 20 couples suggests that many Devadasi sex workers and their intimate partners define their relationships as 'like marriage' which reduced their motivation to use condoms. Evidence from this study suggests that active participation in sex workers' collectives (sanghas) can increase condom use, education and family planning services, among other things, and could be helpful for both Devadasis and their intimate partners to better understand and accept safer sexual practices. Our work has direct implications for designing couple-based health interventions for traditional Devadasi sex workers and their intimate partners in India.

  18. Converging Evidence of Ubiquitous Male Bias in Human Sex Perception.

    Directory of Open Access Journals (Sweden)

    Justin Gaetano

    Full Text Available Visually judging the sex of another can be achieved easily in most social encounters. When the signals that inform such judgements are weak (e.g. outdoors at night, observers tend to expect the presence of males-an expectation that may facilitate survival-critical decisions under uncertainty. The present aim was to examine whether this male bias depends on expertise. To that end, Caucasian and Asian observers targeted female and male hand images that were either the same or different to the observers' race (i.e. long term experience was varied while concurrently, the proportion of targets changed across presentation blocks (i.e. short term experience change. It was thus found that: (i observers of own-race stimuli were more likely to report the presence of males and absence of females, however (ii observers of other-race stimuli--while still tending to accept stimuli as male--were not prone to rejecting female cues. Finally, (iii male-biased measures did not track the relative frequency of targets or lures, disputing the notion that male bias derives from prior expectation about the number of male exemplars in a set. Findings are discussed in concert with the pan-stimulus model of human sex perception.

    Background Sex work is partially regulated in Tijuana, but little is known of its health effects. A recent behavioral intervention among female sex workers (FSWs) decreased incidence of HIV/STIs by 40%. We evaluated effects of sex worker regulation on condom use among FSWs randomized to this intervention. Methods FSWs aged ≥18 years who reported unprotected sex with ≥1 client in the last 2 months and whether they were registered with Tijuana’s Municipal Health Department underwent a brief, theory-based behavioral intervention to increase condom use. At baseline and 6 months, women underwent interviews and testing for HIV, syphilis, C. trachomatis and N. gonorrhoeae. Negative binomial regression was used to determine the effect of registration on numbers of unprotected sex acts and cumulative HIV/STI incidence. Results Of 187 women, 83 (44%) were registered. Lack of registration was associated with higher rates of unprotected sex (rate ratio: 1.7, 95% CI: 1.2–2.3), compared to FSWs who were registered, after controlling for potential confounders. Conclusions Registration predicted increased condom use among FSWs enrolled in a behavioral intervention. Public health programs designed to improve condom use among FSWs may benefit from understanding the impact of existing regulation systems on HIV risk behaviors. PMID:20956076

    Sex work is partially regulated in Tijuana, but little is known of its health effects. A recent behavioural intervention amongst female sex workers (FSWs) decreased incidence of HIV/STIs by 40%. We evaluated effects of sex worker regulation on condom use amongst FSWs randomized to this intervention. FSWs aged ≥18 years who reported unprotected sex with ≥1 client in the last 2 months and whether they were registered with Tijuana's Municipal Health Department underwent a brief, theory-based behavioural intervention to increase condom use. At baseline and 6 months, women underwent interviews and testing for HIV, syphilis, Chlamydia trachomatis and Neisseria gonorrhoeae. Negative binomial regression was used to determine the effect of registration on numbers of unprotected sex acts and cumulative HIV/STI incidence. Of 187 women, 83 (44%) were registered. Lack of registration was associated with higher rates of unprotected sex (rate ratio: 1.7, 95% CI: 1.2-2.3), compared to FSWs who were registered, after controlling for potential confounders. Registration predicted increased condom use amongst FSWs enrolled in a behavioural intervention. Public health programmes designed to improve condom use amongst FSWs may benefit from understanding the impact of existing regulation systems on HIV risk behaviours. Copyright © 2010 Elsevier B.V.

  1. The male handicap: male-biased mortality explains skewed sex ratios in brown trout embryos.

    Juvenile sex ratios are often assumed to be equal for many species with genetic sex determination, but this has rarely been tested in fish embryos due to their small size and absence of sex-specific markers. We artificially crossed three populations of brown trout and used a recently developed genetic marker for sexing the offspring of both pure and hybrid crosses. Sex ratios (SR = proportion of males) varied widely one month after hatching ranging from 0.15 to 0.90 (mean = 0.39 ± 0.03). Families with high survival tended to produce balanced or male-biased sex ratios, but SR was significantly female-biased when survival was low, suggesting that males sustain higher mortality during development. No difference in SR was found between pure and hybrid families, but the existence of sire × dam interactions suggests that genetic incompatibility may play a role in determining sex ratios. Our findings have implications for animal breeding and conservation because skewed sex ratios will tend to reduce effective population size and bias selection estimates. © 2016 The Authors.

    Background The study was conducted to investigate past and future pregnancy preferences and contraceptive need among Malagasy sex workers. Study Design We analyzed data on pregnancy and contraceptive use collected during the baseline visit of a randomized, prospective formative trial which assessed diaphragm and microbicide acceptability among sex workers. To be eligible, women could not be pregnant or planning pregnancy for the next 2 months. Results Women (N=192) from four cities (Antananarivo, Antsiranana, Mahajanga and Toamasina) reported a median of 10 sex acts per week. Fifty-two percent reported a prior unwanted pregnancy, 45% at least one induced abortion and 86% that preventing future pregnancy was moderately to very important. During the last sex act, 24% used a hormonal method, 36% used a male condom, 2% used a traditional method and 38% used no method. Nearly 30% of participants reported that pregnancy prevention was moderately or very important but used no contraception at last sex; these women were categorized as having “unmet need” for contraception. In multivariable binomial regression analyses, factors associated with unmet need included low knowledge of contraceptive effectiveness [age- and site-adjusted prevalence ratio (PR): 2.1; 95% confidence interval (CI): 1.4–3.0] and low self-efficacy to negotiate condom use (age- and site-adjusted PR: 2.0; 95% CI: 1.4–3.0). Conclusions Among these women, prior unwanted pregnancy and induced abortion were common and preventing future pregnancy was important, yet gaps in contraceptive use were substantial. Contraceptive knowledge and self-efficacy should be improved to promote contraceptive use by sex workers. PMID:19185677

    Between 20 and 40 % of female sex workers (FSWs) began sex work before age 18. Little is known concerning whether early initiation of sex work impacts later experiences in adulthood, including violence victimization. This paper examines the relationship between early initiation of sex work and violence victimization during adulthood. The sample included 816 FSWs in Mombasa, Kenya, recruited from HIV prevention drop-in centers who were 18 years or older and moderate-risk drinkers. Early initiation was defined as beginning sex work at 17 or younger. Logistic regression modeled recent violence as a function of early initiation, adjusting for drop-in center, age, education, HIV status, supporting others, and childhood abuse. Twenty percent of the sample reported early initiation of sex work. Although both early initiators and other FSWs reported commonly experiencing recent violence, early initiators were significantly more likely to experience recent physical and sexual violence and verbal abuse from paying partners. Early initiation was not associated with physical or sexual violence from non-paying partners. Many FSWs begin sex work before age 18. Effective interventions focused on preventing this are needed. In addition, interventions are needed to prevent violence against all FSWs, in particular, those who initiated sex work during childhood or adolescence.

    The objective of this study was to assess the factors associated with methamphetamine (MA) use, syphilis, and unprotected sex among female sex workers from different type of venues in Qingdao City, Shandong Province of China. Three consecutive cross-sectional surveys provided information on demographics, sexual and drug use behaviors, and HIV-related services. Of 1187 participants, 3.0% were infected with syphilis; 30.2% ever used MA; 58.3% ever had unprotected commercial sex in the past month. The prevalence rates of syphilis and MA use were 2.5% and 33.0% for participants recruited from saunas, night clubs, bars or hotels; 2.7% and 28.3% for hair/beauty salon-based participants; and 4.5% and 15.8% for street-based participants. Street-based MA users were more likely to be single, non-Shandong residents, have first lifetime sex act at younger age, and recruited in 2008 (vs. 2006). Saunas, night clubs, bars, or hotels-based MA users were more likely to be younger, sex debut at younger age, have longer duration of sex work, have unprotected commercial sex, and be syphilis-infected. Hair/beauty salon-based MA users were more likely to be non-Shandong residents, younger, and to have unprotected commercial sex. Syphilis among the sauna-, night club-, bar-, or hotel-based participants was associated with MA use and ever receipt of HIV testing. Syphilis among the hair/beauty salon-based participants was associated with longer duration of sex work. MA users who frequent commercial sex venues are engaging in high-risk behaviors and are at risk for syphilis/other sexually transmitted diseases. Better-targeted intervention efforts to curtail the epidemics of MA use and HIV/syphilis should therefore take cognizance of the role of commercial sex venues as focal points of MA use and syphilis/sexually transmitted disease transmission.

    This study examined whether job stress (work demand and decision latitude) is associated with smoking, blood pressure, lipid level (total cholesterol, triglyceride, HDL cholesterol), and homocystein as risk factors for cardiovascular disease in Korean male workers. Study subjects of this study were recruited from a sample of 1,071 workers in 20 companies of W city and H counties, and they were grouped into four categories (high strain group, active group, passive group, and low strain group) based on the postulation of Karasek's Job Strain Model. Of them, we invited 160 male workers (40 people each subgroup) using a stratified sampling, and finally, 152 eligible participants were analyzed. In multivariate analyses, we found that decision latitude was associated with cholesterol, triglyceride, and homocystein and that work demand was related to smoking and systolic blood pressure. Job strain (the combination of high work demand with low decision latitude) was significantly related to higher levels of homocystein after controlling for age, BMI, smoking, and social support at workplace. These results indicate that job stress is associated with cardiovascular risk factors and might contribute to the development of cardiovascular disease. Some considerations for the future research were discussed.

  10. Early Resumption of Sex following Voluntary Medical Male Circumcision amongst School-Going Males.

    Directory of Open Access Journals (Sweden)

    Gavin George

    Full Text Available Voluntary medical male circumcision is an integral part of the South African government's response to the HIV and AIDS epidemic. Following circumcision, it is recommended that patients abstain from sexual activity for six weeks, as sex may increase the risk of female-to-male HIV transmission and prolong the healing period. This paper investigates the resumption of sexual activity during the healing period among a cohort of school-going males in the KwaZulu-Natal province of South Africa. The analysis for this paper compares two groups of sexually active school-going males: the first group reported having sex during the healing period (n = 40 and the second group (n = 98 reported no sex during the healing period (mean age: 17.7, SD: 1.7.The results show that 29% (n = 40 of young males (mean age: 17.9, SD: 1.8 who were previously sexually active, resumed sexual activity during the healing period, had on average two partners and used condoms inconsistently. In addition, those males that engage in sexual activity during the healing period were less inclined to practice safe sex in the future (AOR = 0.055, p = 0.002 than the group of males who reported no sex during the healing period. These findings suggest that a significant proportion of young males may currently and in the future, subject themselves to high levels of risk for contracting HIV post circumcision. Education, as part of a VMMC campaign, must emphasize the high risk of HIV transmission for both the males their partners during the healing period.

    Physical and mental health of workers is threatened due to various events and chronic occupational stress. This study was conducted to investigate the relationship between occupational stress and gastric disease in male workers of the shipbuilding industry. Occupational stress measured among a total of 498 workers of a shipbuilding firm who visited the hospital for health examination using the Korean Occupational Stress Scale (KOSS)-short form, and the relationship between sociodemographic factors, health-related behaviors, occupational stress, and gastric disease, and the distribution of occupational stress by sociodemographic factors in the gastric disease group was examined. There was no significant association between gastric disease and total occupational stress score and its seven sub-factors. The analysis showed that risk of gastric disease was significantly higher in the Q1 group in which the stress caused by occupational discomfort among seven sub-factors was lowest than that in the Q4 group (odds ratio, 2.819; 95% confidence interval, 1.151 to 6.908). Analysis only on the gastric disease group showed that the stress score of laborers was higher in the four sub-factors than that of office workers (P occupational stress in the low-educated and laborers. It is recommended for future studies to confirm the causal relationship between occupational stress and gastric disease by large scale studies using a KOSS which appropriately reflects workplace culture.

    Despite the recognized importance of HIV testing in prevention, care and treatment, HIV testing remains low in China. Millions of female sex workers (FSW) play a critical role in China's escalating HIV epidemic. Limited data are available regarding HIV testing behavior among this at-risk population. This study, based on a cross-sectional survey of 1,022 FSW recruited from communities in Southwest China, attempted to address the literature gap. Our data revealed that 48% of FSW ever took HIV testing; older age, less education, working in higher-income commercial sex venues and better HIV knowledge were associated with HIV testing. Those who never took HIV testing were more likely to engage in high-risk behaviors including inconsistent condom use with clients and stable partners. A number of psychological and structural barriers to testing were also reported. We call for culturally appropriate interventions to reduce HIV risks and promote HIV testing for vulnerable FSW in China.

    At an HIV clinic in the Limpopo province of South Africa, chart reviews revealed long delays in addressing abnormal Pap smears, difficulty in referrals, poor quality and lost results, and increasing cases of cervical cancer. To address these barriers, a "see and treat" approach to screening was proposed. The objective was to integrate this method into current HIV care offered by local providers and to obtain demographic and risk factor data for use in future educational and intervention programs in the region. A cross sectional study of HIV farm workers and at-risk sex workers attending an HIV clinic was performed with visual inspection with acetic acid (VIA). Those with positive screens were offered cryotherapy. Clinic charts were reviewed retrospectively for Pap smear results for the previous year at the time of program initiation and at 12 and 18 months post-program. A total of 403 participants consented and underwent screening with VIA (306 Farm workers and 97 sex workers participated). 83.9% of participants (32.9% sex workers and 100% farm workers) were HIV +. VIA was positive in 30.5% of participants, necessitating cryotherapy. There was no significant difference in VIA positivity between HIV + farm workers and sex workers. There was a positive correlation between Pap smears and VIAs results. We demonstrate successful integration of cervical cancer screening using VIA for HIV + farm workers and sex workers into an existing HIV treatment and prevention clinic in rural South Africa, addressing and treating abnormal results promptly.

    Full Text Available Abstract Background Restless Legs Syndrome (RLS is a common neurological movement disorder characterized by symptoms that follow a circadian pattern. Night and rotating shift work schedules exert adverse effects on functions of the human body by disturbing circadian rhythms, and they are known to cause sleep disturbances and insomnia. In this paper, we investigate the possible association between shift work and RLS. Methods This cross sectional study was conducted in an automobile manufacturing factory in Tehran, Iran. A total of 780 male assembly workers were recruited in three groups, each with 260 workers: workers on a permanent morning shift (A and two different rotating shift schedules (B and C with morning, afternoon and night shifts. We used the international RLS study group criteria for diagnosis of RLS, and the severity scale for severity assessment in subjects with RLS. Self administered questionnaires were used to gather information on age, smoking, work history, medical condition, and existence and severity of RLS symptoms. Results The prevalence of RLS was significantly higher in rotational shift workers (15% than workers with permanent morning work schedule (8.5%. In workers suffering from RLS, we found greater mean values of age and work experience, higher percentages of drug consumption, smoking, and co-morbid illnesses compared with subjects who did not have RLS, although these differences were statistically significant only for age, work experience and drug consumption. Conclusion Rotational shift work acts as a risk or exacerbating factor for Restless Legs Syndrome.

    A cross-sectional study was designed to examine the effect of smoking habit on hearing loss at 1000 and 4000 Hz in the workplace. Among 1,875 male workers, including 287 subjects with occupational noise exposure, the ratio of the number with hearing loss at 1000 or 4000 Hz increased with smoking habits and that relation at 4000 Hz was statistically significant. These hearing losses showed a significant relation with age but not with working- duration under occupational noise exposure by multiple regression analysis. The amount of smoking showed a weak but significant association with hearing loss at 4000 Hz. However, among the 287 male subjects with occupational noise exposure, there was no significant relation between smoking habits and hearing loss. Therefore, both hearing loss induced by occupational noise exposure and that related with smoking habit were well controlled in this workplace. These results indicate that hearing check-ups and education to prevent noise-induced hearing impairment in the workplace might be useful to prevent the hearing loss associated with smoking habit among male workers.

    This paper uncovers ‘conspicuous work’ as a new form of status seeking that can explain social interactions in labour supply. We analyse how peer working time relates to both labour supply and happiness for Dutch male workers. Using a unique measure of peer weekly working time, we find that men’s working time increases with that of their peers and that peer working time is negatively related to men’s happiness. These findings are consistent with a ‘conspicuous work’ model, in which individual...

    While sex work is often considered the world's oldest profession, there remains a dearth of research on work stress among sex workers (SWs) in occupational health epidemiological literature. A better understanding of the drivers of work stress among SWs is needed to inform sex work policy, workplace models and standards. To examine the factors that influence work stress among SWs in Metro Vancouver. Analyses drew from a longitudinal cohort of SWs, known as An Evaluation of Sex Workers' Health Access (AESHA) (2010-14). A modified standardized 'work stress' scale, multivariable linear regression with generalized estimating equations was used to longitudinally examine the factors associated with work stress. In multivariable analysis, poor working conditions were associated with increased work stress and included workplace physical/sexual violence (β = 0.18; 95% confidence interval (CI) 0.06, 0.29), displacement due to police (β = 0.26; 95% CI 0.14, 0.38), working in public spaces (β = 0.73; 95% CI 0.61, 0.84). Older (β = -0.02; 95% CI -0.03, -0.01) and Indigenous SWs experienced lower work stress (β = -0.25; 95% CI -0.43, -0.08), whereas non-injection (β = 0.32; 95% CI 0.14, 0.49) and injection drug users (β = 0.17; 95% CI 0.03, 0.31) had higher work stress. Vancouver-based SWs' work stress was largely shaped by poor work conditions, such as violence, policing, lack of safe workspaces. There is a need to move away from criminalized approaches which shape unsafe work conditions and increase work stress for SWs. Policies that promote SWs' access to the same occupational health, safety and human rights standards as workers in other labour sectors are also needed. © The Author 2017.

    This paper assesses the reasons for entry into sex work and its association with HIV risk behaviours among mobile female sex workers (FSWs) in India. Data were collected from a cross-sectional survey conducted in 22 districts across four high HIV prevalence states in India during 2007-2008. Analyses were limited to 5498 eligible mobile FSWs. The reasons given by FSWs for entering sex work and associations with socio-demographic characteristics were assessed. Reported reasons for entering sex work include poor or deprived economic conditions; negative social circumstances in life; own choice; force by an external person; and family tradition. The results from multivariate analyses indicate that those FSWs who entered sex work due to poor economic conditions or negative social circumstances in life or force demonstrated elevated levels of current inconsistent condom use as well as in the past in comparison with those FSWs who reported entering sex work by choice or family tradition. This finding indicates the need for a careful assessment of the pre-entry contexts among HIV prevention interventions since these factors may continue to hinder the effectiveness of efforts to reduce the spread of HIV/AIDS in India and elsewhere.

    Mutual policing is thought to be important in conflict suppression at all levels of biological organization. In hymenopteran societies (bees, ants, and wasps), multiple mating by queens favors mutual policing of male production among workers (worker policing). However, worker policing of male production is proving to be more widespread than predicted by relatedness patterns, occurring in societies headed by single-mated queens in which, paradoxically, workers are more related to the workers' ...

    2014-01-01

    The purposes of this study were to examine the relationship between psychosocial factors and metabolic syndrome among male and female blue-collar workers, and which factors influence their metabolic syndrome by sex. A cross-sectional study was completed of 154 men and 80 women working at small companies in Korea. The data were collected through a structured questionnaire, blood test, and anthropometric and blood pressure measure. Metabolic syndrome was diagnosed from the results of blood test and the measurements of waist circumference and blood pressure. The prevalence of metabolic syndrome among male and female blue-collar workers was 24.0% and 7.5%, respectively. Multiple logistic regression analysis was performed to examine factors of metabolic syndrome associated with sex. After controlling for age, marital status, smoking, alcohol drinking, shift work, overtime work, and physical exercise, job stress (odds ratio [OR] = 3.10, P = 0.005) and risk perception (OR = 1.12, P = 0.016) were influencing factors for men, and low job stress (OR = 0.05, P = 0.04), low social support (OR = 1.51, P = 0.009), and risk perception (OR = 1.27, P = 0.023) for women. Metabolic syndrome among blue-collar workers is closely related to psychosocial factors, such as job stress, social support, and risk perception, with the effect of job stress a point of difference between men and women.

    Little is known about the sexual and reproductive health care needs of female sex workers in Dhaka, Bangladesh. Survey data were collected from 354 hotel-based and 323 street-based female sex workers using a venue-based stratified cluster sampling approach. In addition, in-depth interviews were conducted with 20 female sex workers recruited from drop-in centers. We calculated unmet need for family planning and examined fertility desires, use of condoms and other contraceptive methods, experiences with gender-based violence, sexual and reproductive health service needs, and preferences on where to receive services. The prevalence of unmet need was 25% among hotel-based female sex workers and 36% among street-based female sex workers. Almost all participants reported having used condoms in the past 30 days, and 44% of hotel-based sex workers and 30% of street-based sex workers reported dual method use during that period. Condom use was inconsistent, however, and condom breakage and nonuse for extra money were common. Many women reported experiencing gender-based violence. Sexual and reproductive health services had been obtained by 64% of hotel-based and 89% of street-based sex workers in the past six months; drop-in centers were their preferred site for receiving health services. Female sex workers in Dhaka need family planning and other sexual and reproductive health services and prefer receiving them from drop-in centers.

    Sex workers have historically played a central role in STI outbreaks by forming a core group for transmission and due to their higher rates of concurrency and inconsistent condom usage. Over the past 15 years, North American commercial sex markets have been radically reorganised by internet technologies that channelled a sizeable share of the marketplace online. These changes may have had a meaningful impact on the role that sex workers play in STI epidemics. In this study, two new datasets documenting the characteristics and practices of internet-facilitated sex workers are presented and analysed. The first dataset comes from a ratings website where clients share detailed information on over 94,000 sex workers in over 40 cities between 1999 and 2008. The second dataset reflects a year-long field survey of 685 sex workers who advertise online. Evidence from these datasets suggests that internet-facilitated sex workers are dissimilar from the street-based workers who largely populated the marketplace in earlier eras. Differences in characteristics and practices were found which suggest a lower potential for the spread of STIs among internet-facilitated sex workers. The internet-facilitated population appears to include a high proportion of sex workers who are well-educated, hold health insurance and operate only part time. They also engage in relatively low levels of risky sexual practices.

  6. Performance, power and condom use: reconceptualised masculinities amongst Western male sex tourists to Thailand.

    Each year large numbers of Western men travel to Thailand for sex tourism. Although many will use condoms during their sexual encounters, others will not, potentially exposing themselves to the risk of acquiring sexually transmitted infections, including HIV. Although sex tourism in Thailand has been well documented, the social drivers underpinning voluntary sexual risk-taking through the avoidance of condoms remain poorly understood. Engaging with R.W. Connell's concept of hegemonic masculinity and drawing on data collected from 1237 online discussion board posts and 14 face-to-face interviews, this study considers the ways in which understandings and performances of masculinities may inform the sexual risk-taking behaviours of Western male sex tourists. It argues that for some of these men, unprotected sex is viewed not as a reckless behaviour but, instead, as a safe and appropriate masculine practice, supported by relationships that are often framed as romantic and within a setting where HIV is still largely considered a homosexual disease. With sex workers often disempowered to request safer sexual practices, and some men's attitudes towards unprotected sex resistant to external health promotion advice, the paper concludes by considering what this might mean for policy and practice.

    The attrition of rape cases from the criminal justice system (CJS) remains high and there is a paucity of research in relation to marginalized groups. Sex workers (SWs) are vulnerable to sexual violence due to the nature of their work. They are also unlikely to report such violence to police for a range of reasons. Two stages of research sought to describe the victim, perpetrator, and offense characteristics of SW rape and to examine the attrition of these cases. All rapes and attempted rapes (N = 1,146) reported to police in a large city in the South West of England over a 21-year period were examined; 67 cases involved SWs. Data were extracted from police files in line with the variables of interest. Secondary analysis of the total number of SW rapes (n = 67) resulted in a profile of these cases. A matched pairs study revealed significant differences in victim, perpetrator, and assault characteristics between SW (n = 62) and non-sex-worker (NSW) samples (n = 62). Although no significant difference was found in terms of attrition from the CJS, SW cases were observed to secure more convictions for rape than NSW cases. The implications of the findings for practice and future research are discussed. © The Author(s) 2015.

    Intimate partner violence (IPV) is the most prevalent form of violence against women, yet remains under-researched among sex workers in sub-Saharan Africa. We explored the interpersonal and structural determinants of recent IPV among female sex workers in northern Uganda. This analysis drew on data from a community-based cross-sectional study (conducted May 2011-January 2012), involving 379 female sex workers in Gulu, northern Uganda. Using logistic regression and multivariable modeling, we examined the correlates of recent male-perpetrated physical or sexual IPV. Of 379 women with noncommercial partners, 59 percent reported having experienced recent moderate/severe physical or sexual IPV. Reporting recent client violence (adjusted odds ratio (AOR): 3.67; 95 percent confidence interval [CI]: 2.31-5.83), doing what their partner wanted (AOR: 2.46; 95 percent CI: 1.46-4.13), and forced sexual debut (AOR: 1.92; 95 percent CI: 1.20-3.05) were independently associated with moderate/severe IPV; recent police arrest and/or incarceration were/was marginally significantly associated with IPV (AOR: 2.25; 95 percent CI: 0.86-5.88, p = 0.097). Greater odds of IPV among sex workers were associated with recent workplace violence, forced sexual debut, and gendered power dynamics favoring male partner control. Programs and policies promoting the safety and health of marginalized women and addressing gender dynamics and violence are needed.

    Male migrant workers display high risk sexual behavior and have been shown to have higher prevalence of sexually transmitted infections (STIs), which make them more vulnerable to HIV infection. We aimed to estimate the prevalence of self-reported STIs and delineate their determinants among male migrant factory workers in Faridabad, Haryana. Male workers in two selected factories, who were aged ≥18 years, were born outside Haryana (destination), and who had migrated to Haryana after the age of 15 years were eligible. Socio-demographic information, HIV/AIDS knowledge and behavior, and self-reported STI symptoms in the last 1 year were ascertained by face-to-face interview. Determinants of STIs were identified by regression analysis. Totally 755 eligible workers participated. Mean ± SD age was 31.4 ± 8.2 years and migration duration was 9.5 ± 6.7 years. At least one STI symptom was reported by 41.7% of the participants (burning micturition- 35%, inguinal bubos-5.2%, genital ulcers- 2.6%, urethral pus discharge- 1.3%). Factors associated with STIs were higher age at migration, lower HIV/AIDS knowledge, paid sex in the last year, non-use of condoms during the last non-spousal sex, and unfavorable intention to use condom. Prevalence of self-reported STIs among these migrant men was high. Targeted Interventions among migrant workers need to be strengthened for control and prevention of STIs.

    Conclusion: Sex workers engage in unhealthy sex for social and economic reasons. They should be empowered through vocational training to acquire sustainable sources of income. Regulatory authorities should also work with development partners/Non-governmental organisations (NGOs to package and implement a formidable health strategy/intervention for the control of substance abuse and promotion of safer sex among both the sex workers and their clients.

    Female sex workers have been disproportionately affected with HIV and anal sexual experience elevate their vulnerability. Anal intercourse has more risk of HIV transmission than vaginal intercourse for receptors that coupled with low condom and proper lubricant use behavior during anal sex. Besides majority of them did not understand HIV transmission risk of anal intercourse. In Ethiopia, studies on anal sexual experience is almost none existent, so the purpose of this study is to explored anal sexual experience and HIV transmission risk awareness among female sex worker in Dire Dawa, Eastern Ethiopia. Qualitative study with thematic analysis approach was conducted among 18 female sex workers and recruitment of study participants performed until saturation of information. The principal investigator conducted in-depth interviews using local language (Amharic) and it was recorded on audio recorder. Tape recorded data was transcribed and translated to English and entered into open code version 3.4 for coding and theme identification. Data collection conducted simultaneously with data analysis. Female sex workers practiced anal sex for different themes like financial influence, coercion, intentionally, peer pressure and as a sign of intimacy and love. Coercion, negative attitudes, poor awareness about HIV transmission risks of anal sex and protection capacity of condom and proper lubricants are the identified themes for not using condom and proper lubricants during anal sex by female sex workers. Inaccessibility and unavailability of health services for issues related to anal sex was the core reason for female sex workers' misperception and risk anal sexual experience. Female sex workers practiced anal sex without risk reduction approaches and they did not understand exacerbated risk of anal sex to HIV transmission. Stakeholders including ministry of health need to incorporate potential awareness raising tasks and programs about risk of anal sex and methods of risk

    Previous research indicates that criminalization of sex work is associated with harms among sex workers. In 2013, the Vancouver Police Department changed their sex work policy to no longer target sex workers while continuing to target clients and third parties in an effort to increase the safety of sex workers (similar to "end-demand sex work" approaches being adopted in a number of countries globally). We sought to investigate the trends and correlates of rushing negotiations with clients due to police presence among 359 sex workers who use drugs in Vancouver before and after the guideline change. Data were derived from three prospective cohort studies of people who use drugs in Vancouver between 2008 and 2014. We used sex-stratified multivariable generalized estimating equation models. The crude percentages of sex workers who use drugs reporting rushing client negotiations changed from 8.9% before the guideline change to 14.8% after the guideline change among 259 women, and from 8.6 to 7.1% among 100 men. In multivariable analyses, there was a significant increase in reports of rushing client negotiation after the guideline change among women (p = 0.04). Other variables that were independently associated with increased odds of rushing client negotiation included experiencing client-perpetrated violence (among both men and women) and non-heterosexual orientation (among women) (all p sex workers who use drugs. It was also associated with client-perpetrated violence and other markers of vulnerability. These findings lend further evidence that criminalizing the purchase of sexual services does not protect the health and safety of sex workers.

    The purpose of this study was to examine the relationship between socio-demographic characteristics, risky sexual behaviour, alcohol use and transactional sex among female bar workers in Yaounde, Cameroon. A cross-sectional survey was conducted among a representative sample of 410 female bar workers, recruited through a modified version of venue-based cluster sampling technique from May to June 2017. Transactional sex was defined as having received money/gifts in exchange for sex with any sexual partner in the past 12 months. Logistic regression models were performed to identify the factors associated with transactional sex. The level of statistical significance was set at panalysis showed that those who engaged in transactional sex were more likely to have had sex with a male customer in the past 6 months (aOR = 7.34; 95% CI, 3.63-16.98), had sex under the influence of alcohol in the past 6 months (aOR = 2.42; 95% CI, 1.18-4.96) and frequent alcohol consumers (aOR = 2.06; 95%CI, 1.04-4.10). Respondents who had their last sexual intercourse 4 weeks or more prior to the study (aOR = 0.26; 95% CI, 0.08-0.84) were less likely to have engaged in transactional sex. Our study concludes that female bar workers are exposed to male customers and engage in risky sexual practices including transaction sex. Most of them also consume alcohol which increases their risk of HIV and STI acquisition. They are a high-risk group that need to be targeted with HIV prevention interventions.

    Full Text Available This cross-sectional study assessed the prevalence and correlates of inconsistent refusal of unprotected sex among female sex workers (FSWs in Armenia. One hundred and eighteen street-based FSWs between the ages of 20 and 52 completed a questionnaire assessing FSWs’ demographic, psychosocial, and behavioral characteristics. A total of 52.5% (n=62 of FSWs reported inconsistent refusal of unprotected sex with clients in the past 3 months. Logistic regression analysis controlling for participants’ age and education revealed that perceiving more barriers toward condom use (AOR = 1.1; P<0.01, reporting more types of abuse (AOR = 2.1; P<0.01, and setting lower fees for service (AOR = 0.9; P=0.02 significantly predicted inconsistent refusal of unprotected sex. HIV-risk-reduction behavioral interventions tailored to FSWs working in Yerevan Armenia should address the factors identified in this study toward the goal of enhancing refusal of unprotected sex and ultimately preventing acquisition of sexually transmitted infections (STIs including HIV.

    A qualitative study was conducted to obtain a detailed understanding of two key determinants of condom breakage - 'rough sex' and poor condom fit - identified in a recent telephone survey of female sex workers, in Bangalore, India. Transcripts from six focus-group discussions involving 35 female sex workers who reported condom breakage during the telephone survey were analysed. Rough sex in different forms, from over-exuberance to violence, was often described by sex workers as a result of clients' inebriation and use of sexual stimulants, which, they report, cause tumescence, excessive thrusting and sex that lasts longer than usual, thereby increasing the risk of condom breakage. Condom breakage in this setting is the result of a complex set of social situations involving client behaviours and power dynamics that has the potential to put the health and personal lives of sex workers at risk. These findings and their implications for programme development are discussed.

    Full Text Available Abstract Background The majority of sex work in India is clandestine due to unfavorable legal environment and discrimination against female sex workers (FSWs. We report data on who these women are and when they get involved with sex work that could assist in increasing the reach of HIV prevention activities for them. Methods Detailed documentation of demography and various aspects of sex work was done through confidential interviews of 6648 FSWs in 13 districts in the Indian state of Andhra Pradesh. The demography of FSWs was compared with that of women in the general population. Results A total of 5010 (75.4%, 1499 (22.5%, and 139 (2.1% street-, home-, and brothel-based FSWs, respectively, participated. Comparison with women of Andhra Pradesh revealed that the proportion of those aged 20–34 years (75.6%, belonging to scheduled caste (35.3% and scheduled tribe (10.5%, illiterate (74.7%, and of those separated/divorced (30.7% was higher among FSWs (p 5 years were more likely to be non-street-based FSWs, illiterate, living in small urban towns, and to have started sex work between 12–15 years of age.

Conclusion These data highlight that women struggling with illiteracy, lower social status, and less economic opportunities are especially vulnerable to being infected by HIV, as sex work may be one of the few options available to them to earn money. Recommendations for actions are made for long-term impact on reducing the numbers of women being infected by HIV in addition to the current HIV prevention efforts in India.

    HIV prevalence is increasing in China. The proportion of infection attributable to heterosexual sex in China is also on the rise. The scale of internal migration for work is likely to be one of the factors contributing to these changing patterns, but little is known about HIV-related knowledge, perceptions and risk behaviours of China's migrant workers. This study aimed to investigate HIV-related knowledge, attitudes and risk behaviours of male rural-to-urban migrant workers in Chengdu and to identify factors associated with risk behaviours. In 2005, a cross-sectional questionnaire survey was completed by 163 male construction- and factory-based migrant workers aged 18-35 years. With a mean age of 26 years, just 30% had completed senior middle school and 47% were currently married. Respondents were highly mobile, worked long hours and were relatively poorly paid. As migrants, their access to urban services and benefits was restricted, making it difficult for family members to join them. Knowledge of HIV transmission was generally poor and discriminatory attitudes towards people with HIV were commonplace. Seventy-five percent were sexually experienced, among whom 88% had had sexual relations in the last 12 months. Of these, 30% had had two or more partners and 20% had paid for sex. Just 36% had used a condom during the most recent sexual encounter with a sex worker. Around 70% thought it was 'impossible' for them to become infected, yet a significant sub-group were engaging in sexual behaviours that place them at risk of infection with HIV and sexually transmitted infections (STIs). Logistic Regression found a significant association between having multiple sexual partners and both education level and marital status. Education was also found to be significantly associated with purchasing sex. Targeted HIV-prevention programs for male migrant workers in Chengdu, especially for those who are single and less educated, are urgently needed.

    Sex workers remain a vulnerable population at risk for HIV acquisition and transmission. Research suggests that interventions at the individual level, such as condom distribution, are less effective in preventing HIV among sex workers than structural changes such as allowing safer work settings and reducing the harassment and abuse of sex workers by clients and police. In the US, HIV incidence has not declined in the last decade. This may be due in part to its policy of wilful ignorance about sex work, but the data to resolve the question simply do not exist. Political actions such as PEPFAR's prostitution pledge and a congressional campaign against "waste, fraud and abuse" in research are products of an ideological environment that suppresses research on HIV prevention and treatment needs of sex workers. Even basic prevalence data are missing because there is no "sex worker" category in the US National HIV Behavior Surveillance System. However, international efforts are taking a public health approach and are calling for decriminalization of sex work, as the most effective public health strategy for reducing HIV incidence among sex workers. Although such an approach is not yet politically feasible in the US, some urgent practical policy changes can be implemented to improve data collection and generation of evidence to support HIV prevention and treatment programs targeting sex workers.

    Full Text Available Background: HIV prevalence among female sex workers in Indonesia is among the highest in Asia after Papua New Guinea and Malaysia. Indirect sex workers posed a heightened risk of HIV infection compared to direct sex workers because they usually earn less than their direct counterpart and have lower bargaining power in condom use. Objective: This study aims to examine the factors influencing indirect sex workers’ attitudes toward HIV testing. Methods: This study employed a quantitative method with a cross-sectional approach involved 67 indirect sex workers from massage parlors and beauty salons in Bantul district. Descriptive analysis of respondents’ attitude, perceive threat and expectation was drawn from Health Belief Model Theory. Results: The majority of indirect sex workers had positive attitude towards HIV testing. They are aware to the importance of condom in every commercial sex works, but the majority believe themselves were not susceptible to HIV-AIDS due to their preference to healthy-looking clients to serve sex. Personal expenses to visit the health center for HIV testing are less considered compared to public opinion and discrimination. Peers encouraged the workers to get tested. Disseminating HIV/AIDS information to sex workers through media and mobile phone are not successful. Conclusion: The findings of the study carrying an expectation that when individuals’ attitudes toward HIV testing are positive, the likelihood of getting themselves tested would also be higher. Since the perception is driven by information as stimulus, it is important to provide continuous information to create stimulus which eventually will influence their perception.

    Previous studies have examined sex workers' attitudes to work but not their levels of job satisfaction compared with other occupations. The job satisfaction levels and standards of living of sex workers in licensed brothels in Victoria were compared with Australian women. Responses to a questionnaire that included questions about sex work and their "most likely alternative job." Survey data was compared with identical questions from the Households, Income and Labour Dynamics in Australia Survey. A structured survey was undertaken with sex workers in Victoria attending a a sexual health service. Of the 112 sex workers who agreed to participate in the study, 85 (76%) completed the survey. The median years women had been working as sex workers was three (range 0.1-18). The main reasons women started sex work was because "they needed the money" (69%), were attracted to the flexible hours (44%) or had a particular goal in mind (43%). The two biggest concerns women had about sex work were their safety (65%) and the risk of sexually transmitted infections (65%). When compared with the median job satisfaction scores of Australian women working in sex workers' "most likely alternative jobs," 50% of sex workers reported a higher median satisfaction score for sex work in relation to hours worked, 47% in relation to flexibility, 43% in relation to total pay, 26% in relation to job security, 19% in relation to the work itself, and 25% in relation to overall job satisfaction. Women reported that they primarily do sex work for financial gain although a significant minority prefer it to other work they would be likely to do. These results should be interpreted in the context that the presence of personality disorders that are common among sex workers were not measured in this study. © 2010 International Society for Sexual Medicine.

    A thorough understanding of the environmental and structural factors that precipitate unsafe sexual practices is necessary for HIV/AIDS-prevention research among high-risk population groups like commercial sex workers. I examined how poverty contextualizes sexual health behavior, including condom compliance among commercial female sex workers in a red light district in Calcutta, India. For my research I did an ethnographic study and conducted in-depth interviews of 37 commercial female sex workers. I found that poverty, instead of serving as a catalyst for poor health choices among sex workers, acted as an impetus for pursuing safe sex practices and remaining healthy. The results indicate that sex work, poverty, and health do not always have a paradoxical relationship.

    Sex work research continues to be characterised by debates around decriminalization. Central to these debates are claims about the agency of those involved in the sex trade. Some researchers argue that individuals involved in the sex trade are victims of structural and interpersonal constraint, whilst others depict them as workers exercising choice. Drawing on structure-agency theory, a review of legal and media accounts of the sex trade and qualitative interviews with 21 indoor sex workers in Vancouver, Canada, we argue that both of these perspectives are insufficient. Rather than reducing the sex trade to part of a binary, we suggest that it is necessary to analyse sex work through the complex interplay of both structure and agency. Specifically, structural analyses undercover the numerous ways that sex workers are controlled, observed and influenced whilst agency perspectives elicit the means that sex workers continue to exercise control in spite of disadvantage. While we do not finalise decriminalisation debates, we do critique current Canadian laws for the lack of responsiveness to the lives of sex workers and their exploitative and contradictory stance on sex work.

  9. 'Female condoms give women greater control': a qualitative assessment of the experiences of commercial sex workers in Swaziland.

    To explore commercial sex workers' experiences with the female condom in Swaziland. This is a qualitative study that draws on two focus group discussions and ten individual in-depth interviews with female commercial sex workers in Lavumisa, Swaziland. The findings suggest that the majority of female sex workers prefer to use the female condom with their clients because it offers them greater control over the sexual encounter. Other factors that facilitate its use include the absence of side effects, the enhancement of sexual pleasure and protection against the risk of STIs (including HIV). In addition, the women reported that the female condom is stronger and more resistant to breakage than the male condom. Moreover, the female condoms can be inserted well in advance of sexual intercourse. Difficulties of insertion, partner objection and limited product availability were some of the barriers to the use of the device. There was also a tendency to reuse the female condoms because of lack of product availability and privacy to insert it. Although female condom use involves negotiation with clients, the fact that it offers sex workers an independent method of protection gives them more power and also, increases their ability to control their sexual and reproductive health.

    Research has consistently demonstrated that female sex workers use a variety of empowerment strategies to protect one another and their families. This study examines the strategies Cameroonian sex workers employ to do so. In-depth interviews and focus-group discussions were conducted with 100 sex workers. Coded texts were analysed for recurring themes. Sex workers reported being concerned with physical violence and sexual assault and demands from authorities for bribes to avoid fines and/or imprisonment. Women described strategies such as 'looking out for' each other when faced with security threats. Many reported staying in sex work to provide for their children through education and other circumstances to allow them to lead a better life. Sex worker mothers reported not using condoms when clients offered higher pay, or with intimate partners, even when they understood the risk of HIV transmission to themselves. Concern for their children's quality of life took precedence over HIV-related risks, even when sex workers were the children's primary carers. A sex worker empowerment programme with a focus on family-oriented services could offer an effective and novel approach to increasing coverage of HIV prevention, treatment and care in Cameroon.

    This paper explores barriers to consistent condom use among female sex workers in Jamaica in a qualitative study using grounded theory. Multiple perspectives were sought through 44 in-depth interviews conducted with female sex workers, clients, the partners of sex workers and facilitators of sex work. Poverty and lack of education or skills, severely limited support systems as well as childhood abuse served to push the majority of participants into sex work and created vulnerability to HIV and other STIs. Despite these constraints, women found ways to exercise agency, ensure condom use, adopt protective measures and gain economic advantage in various aspects of the Jamaican sex trade. Perceived relationship intimacy between sex workers and their clients and/or their main partners emerged as the main factor contributing to reduced risk perception and inconsistent condom use. Relationship intimacy, with associated trust and affirmation of self, is the most important factor influencing sexual decision-making with respect to lapse in condom use among female sex workers in Jamaica. Study findings provide important insights that can enhance individual psychosocial, interpersonal and community-based interventions as well as inform environmental, structural and policy interventions to reduce risk and vulnerability among female sex workers.

    Female sex trade workers are among those at highest risk for developing and dying of cervical cancer, and yet many-particularly the most marginalized-are less likely than other women to be screened. This review summarizes global findings on innovative approaches to cervical cancer screening for female sex trade workers, highlights current gaps in the delivery of cervical cancer screening for female sex trade workers globally, and suggests areas for future research and policy development. A scoping review of peer-reviewed publications and grey literature was conducted. Medline (OVID), PubMed, EMBASE, and SCOPUS were searched for relevant studies written in English. There were no limitations placed on dates. Grey literature was identified by hand searching and through discussion with health care providers and community outreach workers currently working with sex trade workers. Twenty-five articles were deemed suitable for review. Articles detailing innovative ways for female sex trade workers to access cervical cancer screening were included. Articles about screening for sexually transmitted infections were also included if the findings could be generalized to screening for cervical cancer. Articles limited to exploring risk factors, knowledge, awareness, education, prevalence, and incidence of cervical cancer among sex trade workers were excluded from the review. Successful screening initiatives identified in the studies reviewed had unconventional hours of operation, understood the difference between street-based and venue-based sex trade workers, and/or used peers for outreach. Two significant gaps in health care service delivery were highlighted in this review: the limited use of unorthodox hours and the nearly exclusive practice of providing sexually transmitted infection screening for female sex trade workers without cervical cancer screening. In addition, although street-based (as opposed to venue-based) sex trade workers are likely at higher risk for

    This study was performed to examine the factors affecting re-smoking in male workers. A self-administrated questionnaire survey was conducted during April 2003 to examine the smoking state of 1,154 employees of a company that launched a smoking cessation campaign in 1998. Five hundred and eighty seven persons, who had stopped smoking for at least one week, were selected as the final study subjects. This study collected data on smoking cessation success or failure for 6 months, and looked at the factors having an effect on resmoking within this period. This study employed the Health Belief Model as its theoretical basis. The re-smoking rate of the 587 study subjects who had stopped smoking for at least one week was 44.8% within the 6 month period. In a simple analysis, the resmoking rates were higher in workers with a low age, on day and night shifts, blue collar, of a low rank, where this was their second attempt at smoking cessation and for those with a shorter job duration (pHeath Belief Model, re-smoking was significantly related with the perceived susceptibility factor, economic advantages of smoking cessation among the perceived benefits factor, the degree of cessation trial's barrier of the perceived barriers factor, smoking symptom experience, recognition of the degree of harmfulness of environmental tobacco smoke and the existence of chronic disease due to smoking (psmoking, the significant variables were age, perceived susceptibility for disease, economic advantages due to smoking cessation, the perceived barrier for smoking cessation, recognition on the degree of harmfulness of environmental tobacco smoke, the existence of chronic disease due to smoking and the number of attempts at smoking cessation (psmoking ban policy within the work place, health education that improves the knowledge of the adverse health effects of smoking and the harmfulness of environmental tobacco smoke will be required, as well as counter plans to reduce the barriers for smoking

    In Peru, commercial sex involving men and male-born travestis, transgenders and transsexuals (CSMT) is usually represented as a dangerous practice carried out on the streets by people experiencing economic hardship and social exclusion. However, in reality little is known about the complexities of this practice in Peru. This paper presents findings from an ethnographic study of the characteristics, patterns and sociocultural aspects of CSMT in three Peruvian cities. The study included participant observation in sex work venues and interviews with 42 sex workers and 25 key informants. We found that CSMT in Peru takes many forms (some not previously described in the country) and is practised in different places by people from various socioeconomic levels. In many cases, the practice appears linked to ideals of social mobility, migratory experiences and other economic activities. In addition, the increasing use of the Internet and mobile phones has changed patterns of sex work in Peru. We review the implications of these findings for future research and public health interventions.

    Social support can affect health outcomes of female sex workers. In this inductive feminist grounded theory study based on 20 in-depth interviews, we explore how establishment-based female sex workers in Tijuana perceive the impact of the connections among women on their lives and health. Participants elected to discuss the importance of social support from mothers, sisters, friends, and co-workers, and the empowering and disempowering aspects of these relationships. In previous studies, scholars demonstrated the efficacy of formal organization of female sex workers in promoting the mitigation of sexual and HIV risk. We show the importance of informal ties with other women. Some participants mentioned competitive relationships, others talked about cooperation and the desire for a venue to learn from one another. Social interactions with other women are especially empowering when female sex workers can openly engage in "woman talk" that may contribute to the mitigation of sexual and HIV risk. © The Author(s) 2015.

    Objective: To do clinical, hormonal and chromosomal analysis in undervirilized male / XY disorder of sex development and to make presumptive etiological diagnosis according to the new Disorder of Sex Development (DSD) classification system. Study Design: Case series. Place and Duration of Study: Endocrine Unit at National Institute of Child Health, Karachi, Pakistan, from January 2007 to December 2012. Methodology: Patients of suspected XY DSD / undervirilized male visiting endocrine clinic were enrolled in the study. Criteria suggested XY DSD include overt genital ambiguity, apparent female/male genitalia with inguinal/labial mass, apparent male genitalia with unilateral or bilateral non-palpable testes, micropenis and isolated hypospadias or with undescended testis. The older children who had delayed puberty were also evaluated with respect to DSD. As a part of evaluation of XY DSD, abdominopelvic ultrasound, karyotype, hormone measurement (testosterone, FSH, LH), FISH analysis with SRY probing, genitogram, laparoscopy, gonadal biopsy and HCG stimulation test were performed. Frequencies and percentages applied on categorical data whereas mean, median, standard deviation were calculated for continuous data. Results: A total of 187 patients met the criteria of XY DSD. Age ranged from 1 month to 15 years, 55 (29.4%) presented in infancy, 104 (55.6%) between 1 and 10 years and 28 (15%) older than 10 years. Twenty five (13.4%) were raised as female and 162 as (86.6%) male. The main complaints were ambiguous genitalia, unilateral cryptorchidism, bilateral cryptorchidism, micropenis, delayed puberty, hypospadias, female like genitalia with gonads, inguinal mass. The karyotype was 46 XY in 183 (97.9%), 46 XX in 2 (1.1%), 47 XXY in 1 (0.5%), 45 X/46 XY in 1 (0.5%) patient.

    Sex hormone receptors were quantitated in normal male rat liver and in regenerating liver at several different times after partial (70%) hepatectomy. Both estrogen and androgen receptor content were altered dramatically by partial hepatectomy. Total hepatic content and nuclear retention of estrogen receptors increased, with the zenith evident 2 days after partial hepatectomy, corresponding to the zenith of mitotic index. Serum estradiol increased after 1 day, and reached a maximum at 3 days after surgery. In contrast, total and nuclear androgen receptor content demonstrated a massive decline at 1, 2, and 3 days after resection. Serum testosterone displayed a parallel decline. In addition, hepatic content of two androgen-responsive proteins was reduced to 15% and 13% of normal values during this period. The activity of these various proteins during regeneration of male rat liver is comparable to that observed in the liver of normal female rats. Taken together, these results indicate that partial hepatectomy induces a feminization of certain sexually dimorphic aspects of liver function in male rats. Furthermore, these data provide evidence that estrogens, but not androgens, may have an important role in the process of liver regeneration. PMID:3758617

    The spectrum of vitamin D (VD)-mediated effects has expanded in recent years, and VD is now recognized as a versatile signaling molecule rather than being solely a regulator of bone health and calcium homeostasis. One of the recently identified target areas of VD is male reproductive function. The VD receptor (VDR) and the VD metabolizing enzyme expression studies documented the presence of this system in the testes, mature spermatozoa, and ejaculatory tract, suggesting that both systemic and local VD metabolism may influence male reproductive function. However, it is still debated which cell is the main VD target in the testis and to what extent VD is important for sex hormone production and function of spermatozoa. This review summarizes descriptive studies on testicular VD metabolism and spatial distribution of VDR and the VD metabolizing enzymes in the mammalian testes and discusses mechanistic and association studies conducted in animals and humans. The reviewed evidence suggests some effects of VD on estrogen and testosterone biosynthesis and implicates involvement of both systemic and local VD metabolism in the regulation of male fertility potential.

    Sex work occurs in many forms and sex workers of all genders have been affected by HIV epidemics worldwide. The determinants of HIV risk associated with sex work occur at several levels, including individual biological and behavioural, dyadic and network, and community and social environmental levels. Evidence indicates that effective HIV prevention packages for sex workers should include combinations of biomedical, behavioural, and structural interventions tailored to local contexts, and be led and implemented by sex worker communities. A model simulation based on the South African heterosexual epidemic suggests that condom promotion and distribution programmes in South Africa have already reduced HIV incidence in sex workers and their clients by more than 70%. Under optimistic model assumptions, oral pre-exposure prophylaxis together with test and treat programmes could further reduce HIV incidence in South African sex workers and their clients by up to 40% over a 10-year period. Combining these biomedical approaches with a prevention package, including behavioural and structural components as part of a community-driven approach, will help to reduce HIV infection in sex workers in different settings worldwide.

    To assess the proportion of independent indoor female sex workers (FSW) in West Yorkshire, UK who advertise unprotected sex, and to investigate any association with cost, location and provision of anal sex. Data on whether independent indoor FSW (defined as those not advertising via an escort agency or through a parlour) advertised unprotected sexual services, along with demographic data, were collected from 462 advertisement profiles of FSW in West Yorkshire from the website http://www.adultwork.com. Independent t test and χ(2) statistics were used to test the association between advertised unprotected vaginal and oral sex, and FSW age, cost of services, location and whether they advertised anal sex. Unprotected vaginal sex was advertised by 8% of FSW, and unprotected oral sex by 74% of FSW. FSW advertising unprotected vaginal sex were more likely to live in Wakefield and Bradford than in Leeds, had significantly lower hourly rates, and were more likely to advertise anal sex. Advertised condom use for vaginal and oral sex by independent indoor FSW in West Yorkshire was significantly lower than reported rates of protected sex found in previous studies based in London and the south of England. The advertisement of unprotected vaginal sex is associated with factors such as lower hourly rates and the advertisement of higher risk anal sex, which may signify greater economic need. FSW offering unprotected sex therefore represent an at-risk target group for health promotion.

    Our objective was to assess if female sex workers (FSWs) and their potential male clients in Cotonou, Benin, know how to use male condoms correctly. From April to June 2000, 314 FSWs and 208 men were interviewed, and asked to demonstrate on a wooden penis how they usually use male condoms. In all, 27.6% of both women and men tore the condom envelope on the notch; 89.3% of the women versus 75.4% of the men easily found the correct side; 17.3% of the women versus 28.3% of the men held the top of the condom to avoid air entering; 91.4% of the women versus 75.6% of the men correctly unrolled the condom. Taking all the four criteria together, only approximately 11% of participants performed a correct condom use demonstration. FSWs frequently reported condom breakage, which was significantly associated with incorrect condom demonstration (P = 0.04). Correct condom use is suboptimal in these heavy consumers of male condoms in Benin. Condom breakage is frequent and is associated with incorrect use.

    This study investigated the intensity of cigarette consumption and its correlates in China among urban male factory workers, a cohort especially vulnerable to tobacco exposure, one that appears to have benefitted little from recent public health efforts to reduce smoking rates. Data were collected from men working in factories of Kunming city, Yunnan, China, who are current daily smokers (N = 490). A multinomial logistic regression was conducted to examine the factors in association with smoking intensity in light, moderate, and heavy levels. Light smoking correlated with social smoking, smoking the first cigarette later in the day, self-reported health condition, and quit intention. Heavy smoking was associated with purchase of lower priced cigarettes, difficulty refraining from smoking, and prehypertensive blood pressure. Even in regions where smoking is highly prevalent, even among cohorts who smoke heavily, variation exists in how cigarettes are consumed. Analyses of this consumption, with special consideration given to smoking intensity and its correlates, can help guide tobacco-control strategists in developing more effective interventions. © 2013 APJPH.

    Fractionated nerve conduction, vibrotactile sense, and temperature thresholds were studied in 73 symptomatic vibration-exposed male workers. Three symptomatic groups were distinguished: patients with isolated sensorineural symptoms; with isolated vasospastic problems; and with both. Clinical carpal tunnel syndrome occurred in 14 patients and abnormal cold intolerance (without blanching of the fingers) in 23. In the group as a whole, nerve conduction studies were abnormal in the median nerve but not in the ulnar nerve and vibration perception and temperature thresholds were impaired. Of the three symptomatic groups, patients with isolated sensorineural symptoms differed from controls. No differences were seen between patients with and without clinical carpal tunnel syndrome. With severe sensorineural symptoms the vibration perception thresholds, but not the values of the nerve conduction studies, were further impaired. The results indicated two injuries that are easily confused: one at receptor level in the fingertips and one in the carpal tunnel. Careful clinical assessment, neurophysiological testing, and examination of vibrotactile sense are required before carpal tunnel release should be considered in these patients.

    Objective: To investigate the relationship between shift work and overweight/obesity in male steel workers. Methods: A questionnaire survey was conducted among the male steel workers selected during health examination in Tangshan Steel Company from March 2015 to March 2016. The relationship between shift work and overweight/obesity in the male steel workers were analyzed by using logistic regression model and restricted cubic splinemodel. Results: A total of 7 262 male steel workers were surveyed, the overall prevalence of overweight/obesitywas 64.5% (4 686/7 262), the overweight rate was 34.3% and the obesity rate was 30.2%, respectively. After adjusting for age, educational level and average family income level per month by multivariable logistic regression analysis, shift work was associated with overweight/obesity and obesity in the male steel workers. The OR was 1.19(95% CI : 1.05-1.35) and 1.15(95% CI : 1.00-1.32). Restricted cubic spline model analysis showed that the relationship between shift work years and overweight/obesity in the male steel workers was a nonlinear dose response one (nonlinear test χ 2 =7.43, P shift work years and obesity in the male steel workers was a nonlinear dose response one (nonlinear test χ 2 =10.48, P Shift work was associated with overweight and obesity in the male steel workers, and shift work years and overweight/obesity had a nonlinear relationship.

  14. SEX WORK, LAW, AND VIOLENCE: BEDFORD V. CANADA AND THE HUMAN RIGHTS OF SEX WORKERS

    Directory of Open Access Journals (Sweden)

    2013-02-01

    Full Text Available In Bedford v. Canada, two levels of Ontario courts ruled that a selection of criminal laws prohibiting prostitution-related activities unjustifiably deprive sex workers of their right to liberty and security of the person.The courts struck down or modified some of the offending provisions to ensure that sex workers are better able to take precautions against violence. While sex workers consider the Ontario Superior Court of Justice ruling a victory and the Ontario Court of Appeal ruling a partial victory, the government, some women’s rights groups, and other defenders of the provisions argue that courts ventured into a “policy thicket”, which is to suggest that they had stepped outside of their legitimate institutional role. Associated concerns include that the decisions effectively constitutionalize prostitution and will pre-empt or curtail Parliament’s consideration of legislative options.      In this paper, the authors clarify misconceptions about the constitutional foundations and implications of Bedford, and explore how the ruling might affect legal and policy-based interactions among various stakeholders. Approaching constitutional rights as discursive mechanisms, rather than as “trumps”, we argue that Bedford will not hinder the continuation of democratic debate about whether, how, and why aspects of sex work should be regulated. To the contrary, Bedford is more likely to enhance the quality of debates by making them more inclusive of the perspectives of sex workers as well as accommodative of growing empirical research that has hitherto been ignored or misrecognized.   Dans l’affaire Bedford v. Canada, deux tribunaux ontariens ont conclu que des dispositions législatives du droit criminel interdisant les activités liées à la prostitution privaient de façon injustifiée les travailleurs et travailleuses du sexe du droit à la liberté et à la sécurité de leur personne. Ces tribunaux ont d

    Between May and October 1992, 374 sex workers comprising of 372 prostitutes and 2 homosexuals were examined for Pthirus pubis infestation. While none of the homosexuals was found to be infested, 52.69% of the prostitutes were infested with the highest and lowest infestation in the 40-49 year old group and 20-29 year old group respectively. The educational level was found to determine the extent of disease awareness among the sex workers. Questions are raised about the role of Pthirus pubis is AIDS transmission among sex workers.

    South Africa is experiencing significant changes in patterns of illicit drug use, including increasing injection and non-injection drug use, and the use of drugs by persons engaged in sex work, both of which could further expand the HIV/AIDS epidemic. In 2005, a rapid ethnographic assessment was conducted in Durban, South Africa, to learn more about patterns of drug use and HIV risk behaviors among drug-using, street-based sex workers. Field teams recruited 52 current injection and non-injection drug users for key informant interviews and focus groups, and they conducted mapping and observation in identified high-risk neighborhoods. Key informants were offered free, voluntary counseling and HIV rapid testing. The results of the assessment indicate that in this population, drugs play an organizing role in patterns of daily activities, with sex work closely linked to the buying, selling, and using of drugs. Participants reported using multiple drugs including crack cocaine, heroin, Ecstasy and Mandrax, and their choices were based on their expectations about the functional role and behavioral and pharmacological properties of the drugs. The organization of sex work and patterns of drug use differ by gender, with males exercising more control over daily routines and drug and sexual transactions than females. Activities of female sex workers are subject to considerable control by individual pimps, many of whom also function as landlords and drug dealers. A strong hold over the overlapping economies of drugs and sex work by a few individuals extends to control of the physical and social settings in which sex is exchanged and drugs are sold and used as well as the terms under which sex work is carried out. The potential for accelerated HIV spread is considerable given the evidence of overlapping drug-using and sexual risk behaviors and the mixing patterns across drug and sexual risk networks.

    Female sex work is often perceived as women being controlled by men. We used surveys and qualitative interviews with female sex workers and their intimate partners in two Northern Mexico cities to examine couples' own perceptions of their relationships and male partners' involvement in sex work. Among 214 couples, the median age was 34 and relationship duration was approximately 3 years. Only 10 women in the survey reported having a pimp, and the majority reported sole control over sex work decisions. Qualitative analyses revealed that while most men avoided direct involvement in sex work, they offered advice that was largely driven by concern for their partner's well-being. Our discussion of these results considers the broader socio-political context surrounding these relationships and how changing gender roles, economic insecurity and stigma shape couples' everyday social interactions. Assumptions that all sex workers' relationships are coercive and commercial marginalises these couples while leaving their health concerns unaddressed.

    Good work ability is very important in young workers, but knowledge of work situations that influence work ability in this group is poor. The aim of this study was to assess whether changes in self-reported work factors are associated with self-reported work ability among young female and male workers. A sample of 1,311 (718 women and 593 men) was selected from a Swedish cohort of workers aged 21-25 years. At baseline and at 1-year follow-up, participants completed a self-administrated questionnaire including ratings of physical and psychosocial work factors and current work ability. Prevalence ratios were calculated to assess univariate and multivariate associations between changes in work factors and changes in work ability. Decreased job control (PR 1.7, 95% CI 1.49-2.12) and increased negative influence of job demands on private life (PR 1.5, 95% CI 1.25-1.69) were associated with reduced work ability for both female and male workers in the multivariate analyses. Among female workers, an association was found between improved work ability and increased social support at work (PR 2.4, CI 1.43-3.95). For male workers, increased job control (PR 2.3, 95% CI 1.21-4.54) and decreased negative influence of job demands on private life (PR 2.1, 95% CI 1.10-3.87) were associated with improved work ability in the multivariate analyses. Decreased job control and increased negative influence of job demands on private life over time seem to be the most important work factors associated with reduced work ability among young workers of both sexes. Increased social support at work, increased job control, and decreased negative influence of job demands on private life were also found to be the main work factors associated with improved work ability, although with possible gender differences.

    Commercial sex work is one of the driving forces of the HIV epidemic across the world. In Vietnam, although female sex workers (FSWs) carry a disproportionate burden of HIV, little is known about the risk profile and associated factors for HIV infection among this population. There is a need for large-scale research to obtain reliable and representative estimates of the measures of association. This study involved secondary data analysis of the 'HIV/STI Integrated Biological and Behavioral Surveillance' study in Vietnam in 2009-2010 to examine the correlates of HIV among FSWs. Data collected from 5298 FSWs, including 2530 street-based sex workers and 2768 venue-based sex workers from 10 provinces in Vietnam, were analyzed using descriptive statistics and bivariate and multivariate logistic regression analyses. HIV prevalence among the overall FSW population was 8.6% (n = 453). However, when stratified by FSW subpopulations, HIV prevalence was 10.6% (n = 267) for street-based sex workers and 6.7% (n = 186) for venue-based sex workers. Factors independently associated with HIV infection in the multivariate analysis, regardless of sex work types, were injecting drug use, high self-perceived HIV risk, and age ≥ 25 years. Additional factors independently associated with HIV risk within each FSW subpopulation included having ever been married among street-based sex workers and inconsistent condom use with clients and having sex partners who injected drugs among venue-based sex workers. Apart from strategies addressing modifiable risk behaviours among all FSWs, targeted strategies to address specific risk behaviours within each FSW subpopulation should be adopted. © The Author(s) 2016.

    Infection with Entamoeba histolytica ( E. histolytica ) can be potentially transmitted by sexual contact. The seroepidemiology of E. histolytica in female sex workers has not been studied. The aim of the study was to determine whether E. histolytica is associated with the occupation of female sex work. In addition, the correlates of E. histolytica seroprevalence in female sex workers were also investigated. We performed an age- and gender-matched case-control study of 187 female sex workers and 374 women without sex work. Cases and controls were tested for the presence of E. histolytica IgG antibodies using a commercially available enzyme-linked immunoassay. Seroprevalence association with the characteristics of female sex workers was determined by bivariate analysis. Anti- E. histolytica IgG antibodies were found in five (2.7%) of 187 female sex workers and in 16 (4.3%) of 374 controls (odds ratios (OR) = 0.61; 95% confidence intervals (CI): 0.22 - 1.70; P = 0.34). Mean optical density of the immunoassay in seropositive cases and controls was 1.35 ± 0.93 and 0.73 ± 0.45, respectively (P = 0.05). Seroprevalence of E. histolytica infection did not vary significantly with age, education, socioeconomic level, or health status of sex workers. Seropositivity to E. histolytica did not correlate with work characteristics such as duration in the occupation, condom use, type of sex, or a history of sexually transmitted diseases, or with behavioral variables such as washing hands before eating, or consumption of untreated water. Results indicate that female sex workers do not have an increased risk for E. histolytica infection in Durango City, Mexico. Further studies to determine the risk of infection with E. histolytica by sexual contact should be conducted.

    Full Text Available ABSTRACT Objective: To assess the prevalence of smoking and associated variables in female sex workers (FSWs Methods: This was a quantitative cross-sectional study involving FSWs in the city of Botucatu, Brazil, who completed a sociodemographic questionnaire, including data regarding smoking status, motivational stage of change, and degree of nicotine dependence, as well as the Perceived Stress Scale and the Hospital Anxiety and Depression Scale Results: We included 83 FSWs. The mean age was 26.8 years. Among the participants, 58 (69.8% had at least a high school education, only 26 (31.3% resided in the city of Botucatu, 59 (71.1% were smokers, 5 (6.0% were former smokers, 74 (89.2% regularly consumed alcohol, and 43 (51.8% used illicit drugs. The majority of the women were classified as having an intermediate stress level, and 51 (61.4% were classified as having possible or probable anxiety, whereas depression was found to be improbable in 57 (68.7%. The level of nicotine dependence was high among the smokers, the majority of whom showed no intention to quit smoking. Smoking was associated with illicit drug use (p = 0.0271 and with alcohol consumption (p = 0.0001, although not with the levels of stress, anxiety, or depression; nor was the age at smoking initiation associated with the length of time as an FSW (p = 0.4651 Conclusions: The prevalence of smoking among the FSWs evaluated here was much higher than the 8.3% reported for the overall female population of Brazil. Our findings show that FSWs are exposed to various risk factors inherent to their profession. Therefore, harm reduction is an important strategy to be adopted.

    We reviewed evidence from over 800 studies and reports on the burden and HIV impact of human rights abuses against sex workers across policy climates. Published research documents widespread abuses of human rights perpetrated by both state and non-state actors. Such violations facilitate HIV vulnerability, both directly and indirectly, and undermine effective HIV prevention and intervention efforts. Violations include homicide, physical and sexual violence from law enforcement, clients and intimate partners, unlawful arrest and detention, discrimination in accessing health services, and forced HIV testing. Abuses occur across all policy regimes, though most profoundly so where sex work is criminalized through punitive law. Protection of sex workers’ human rights is critical to respect, protect and fulfill human rights, and to improve their health and wellbeing. Findings affirm the value of rights-based HIV responses for sex workers, and underscore the obligation of states to uphold the rights of this marginalized population. PMID:25059943

    Full Text Available Abstract Background Recent surveillance data from Bangladesh indicate rising HIV infection among intravenous drug users (IDU in the country. We suggest a likely association between HIV risk factors in this group and other groups, such as males who have sex with males (MSM. Methods Data on MSM in Bangladesh was collected and analyzed from numerous primary and secondary sources, including government ministries, non-profit health organizations, and personal communications. Results The overall prevalence of HIV in Bangladesh is relatively low, but surveillance data indicate that infection has reached significant proportions in certain high-risk groups and may soon spread to other groups, specifically MSM. Conclusion The epidemiology of HIV infection in other countries suggests that increasing rates of HIV in higher-risk populations can precede an epidemic in the general population. We review the data concerning MSM, IDU and HIV in Bangladesh from a variety of sources and propose ways to prevent HIV transmission.

    Unprotected sexual intercourse exposes the female genital tract (FGT) to semen-derived antigens, which leads to a proinflammatory response. Studies have shown that this postcoital inflammatory response can lead to recruitment of activated T cells to the FGT, thereby increasing risk of HIV infection. The purpose of this study was to evaluate the impact of sex work on activation and memory phenotypes of peripheral T cells among female sex workers (FSW) from Nairobi, Kenya. Thirty FSW were recruited from the Pumwani Sex Workers Cohort, 10 in each of the following groups: HIV-exposed seronegative (at least 7 years in active sex work), HIV positive, and New Negative (HIV negative, less than 3 years in active sex work). Blood was obtained at three different phases (active sex work, abstinence from sex work-sex break, and following resumption of sex work). Peripheral blood mononuclear cells were isolated and stained for phenotypic markers (CD3, CD4, CD8, and CD161), memory phenotype markers (CD45RA and CCR7), activation markers (CD69, HLA-DR, and CD95), and the HIV coreceptor (CCR5). T-cell populations were compared between groups. In HIV-positive women, CD8+CCR5+ T cells declined at the sex break period, while CD4+CD161+ T cells increased when returning to sex work. All groups showed no significant changes in systemic T-cell activation markers following the interruption of sex work, however, significant reductions in naive CD8+ T cells were noted. For each of the study points, HIV positives had higher effector memory and CD8+CD95+ T cells and lower naive CD8+ T cells than the HIV-uninfected groups. Interruption of sex work had subtle effects on systemic T-cell memory phenotypes.

    To determine the social and behavioural factors associated with condom use among direct sex workers in Siem Reap, Cambodia. Using a structured behavioural questionnaire, interviews were conducted with 140 direct sex workers attending a health centre in Siem Reap for HIV screening. Consistent condom use with their clients was reported by 78% of sex workers compared to only 20% with their non-paying partners. Consistent condom use with clients was significantly higher among higher income than lower income sex workers (adjusted prevalence ratio: 1.91, 95% CI: 1.15 to 3.18) and those with good rather than poor negotiation skills (adjusted prevalence ratio: 1.51, 95% CI: 1.01 to 2.26), after adjustment for age, educational level, marital status, number of sexual encounters per week, and knowledge of AIDS/HIV and sexually transmitted infections. The most frequently reported reason for not using condoms with clients was not being able to persuade them (66.7%), while for non-paying partners, the reason was that they loved them (60.0%). To complement the government's current programme of client education, 100% condom policy and brothel administrative measures, additional strategies to increase condom use among clients and non-paying partners should be directed at (i) the social policy and community levels to address sex workers' economic and cultural barriers to condom use, and (ii) personal level empowerment through developing sex workers' condom negotiation skills.

    To assess the differences in the prevalence of muscarinic and nicotinic type symptoms and the level of erythrocytic cholinesterase, prior to pesticide exposure, in male and female migrant agricultural workers. A cross-sectional study was carried out in 2001 in Sinaloa State, Mexico, among 488 migrant workers. A questionnaire was applied and erythrocytic cholinesterase levels were measured before the beginning of the agricultural season. The differences by sex were compared using the "t" test for continuous variables and chi2 test for categorical variables. Prevalence odds ratios were also estimated. Statistical significance was assessed using p-values migration type, place of origin, education, and migration time (p=0.000). Women were six times more likely to have anemia and asthma, twice more likely to have parasites and respiratory and gastrointestinal diseases and 38% more likely to suffer from heart disease. They were also at greater prevalence in thirteen of nineteen investigated symptoms. The average cholinesterase level was within normal limits (4.22 U/ml+/-0.77) and it was similar to the levels reported using the Magnotti method. The prevalence of symptoms, illnesses and cholinesterase levels found in this study may serve as baseline values for future comparisons of the health effects of pesticide exposure.

    Female sex workers and their clients remain a high risk core group for HIV in Africa. We measured sexual behavior of a snowball sample of female sex workers (FSW) along the Trans Africa highway from Mombasa, Kenya to Kampala, Uganda and surveyed the availability of male condoms at 1,007 bars and lodgings in Kenya along the highway trucking stops where transactional sex occurs. There were 578 FSW one month sex diaries analyzed, 403 from Kenya and 175 from Uganda. Kenyan FSW had a median of 45 sexual acts per 28 days compared to 39 sex acts per 28 days by Ugandan FSW (P lodges in Kenya compared to Uganda were more likely to: have condom dispensers, 25% versus 1%, respectively (P < 0.01); distribute or sell condoms, 73.9% versus 47.6% (P < 0.01); and have more weekly condom distribution, 4.92 versus 1.27 condoms per seating capacity (P < 0.01). Our data indicate that in both countries condom use for FSW is suboptimal, particularly with regular partners, and greater condom use by Trans African highway FSW in Kenya compared to Uganda may be related to availability. Targeted interventions are warranted for FSW and truck drivers to prevent transmission in this important core group.

    Despite reports of high levels of violence among women migrants in Central America, limited evidence exists regarding the health and safety of migrant sex workers in Central America. This study is based on 16 months of field research (November 2012-February 2014), including ethnographic fieldwork, in-depth interviews, and focus groups conducted with 52 internal and international migrant female sex workers in Tecún Umán and Quetzaltenango, Guatemala, key transit and destination communities for both international and internal migrants. The analysis explored migration-related determinants of susceptibility to violence experienced by migrant sex workers across different phases of migration. Violence in home communities and economic considerations were key drivers of migration. Unsafe transit experiences (eg undocumented border crossings) and negative interactions with authorities in destination settings (eg extortion) contributed to migrant sex workers' susceptibility to violence, while enhanced access to information on immigration policies and greater migration and sex work experience were found to enhance agency and resilience. Findings suggest the urgent need for actions that promote migrant sex workers' safety in communities of origin, transit, and destination, and programmes aimed at preventing and addressing human rights violations within the context of migration and sex work.

    To examine the prevalence and structural correlates of gender based violence against female sex workers in an environment of criminalised prostitution. Prospective observational study. Vancouver, Canada during 2006-8. Female sex workers 14 years of age or older (inclusive of transgender women) who used illicit drugs (excluding marijuana) and engaged in street level sex work. Self reported gender based violence. Of 267 female sex workers invited to participate, 251 women returned to the study office and consented to participate (response rate of 94%). Analyses were based on 237 female sex workers who completed a baseline visit and at least one follow-up visit. Of these 237 female sex workers, 57% experienced gender based violence over an 18 month follow-up period. In multivariate models adjusted for individual and interpersonal risk practices, the following structural factors were independently correlated with violence against female sex workers: homelessness (adjusted odds ratio for physical violence (aOR(physicalviolence)) 2.14, 95% confidence interval 1.34 to 3.43; adjusted odds ratio for rape (aOR(rape)) 1.73, 1.09 to 3.12); inability to access drug treatment (adjusted odds ratio for client violence (aOR(clientviolence)) 2.13, 1.26 to 3.62; aOR(physicalviolence) 1.96, 1.03 to 3.43); servicing clients in cars or public spaces (aOR(clientviolence) 1.50, 1.08 to 2.57); prior assault by police (aOR(clientviolence) 3.45, 1.98 to 6.02; aOR(rape) 2.61, 1.32 to 5.16); confiscation of drug use paraphernalia by police without arrest (aOR(physicalviolence) 1.50, 1.02 to 2.41); and moving working areas away from main streets owing to policing (aOR(clientviolence) 2.13, 1.26 to 3.62). Our results demonstrate an alarming prevalence of gender based violence against female sex workers. The structural factors of criminalisation, homelessness, and poor availability of drug treatment independently correlated with gender based violence against street based female sex workers. Socio

    Sex work in exchange for kind and cash has long been practiced in Nepal. The HIV prevention program in Nepal is focused mainly on these two typologies of sex work. There might be more typologies of sex work beyond streets and establishments seeking research and programmatic attention. The objective of the study is to explore the differentiated typologies of sex work. This is a cross-sectional study conducted using a qualitative technique. Researchers carried out eight Focus Group Discussions with female sex workers (FSWs) (n = 50) in different places of Tanahu district. Data were analyzed using a deductive thematic analysis approach. We identified a more differentiated typology of sex work. Private contact-based sex work and the covert sex work on the cruising areas along the major highways were common. Sex work has become easier to operate with the advent of new technologies such as cell phone. With limited role of facilitation by brokers and pimps, now FSWs are better off and have longer duration of relationship with clients. Soft prostitution was common, as FSWs complemented their income through sex work. The conventional mode of peer and outreach educational approach needs to be further strengthened and modified according to the changing typology of sex work. HIV testing sites need to be further expanded to cruising areas along the highways.

    HIV among people who inject drugs (PWID) is a major public health challenge in India. This paper examines PWID in Delhi who also have male-to-male sex with a focus on overlapping HIV risk behaviours and the psychosocial correlates of a history of male-to-male anal sex. We analysed data collected in April-May of 2012 from a community-based sample of 420 male PWID in Delhi obtained using time location sampling. One third (37%) of the men reported a history of anal sex with men, among whom just 16% used a condom at last anal sex. Almost all (93%) participants who had a history of anal sex with men also had sex with women. Chi-square tests revealed that a history of anal sex with men was associated with a higher number of female sexual partners and sharing of needles and syringes. Additionally, unprotected sex at last sex with a male partner was significantly associated with unprotected sex at last sex with regular and paid female partners. Multivariate binary logistic regression revealed that the psychosocial correlates of a history of anal sex with other men were: being aged 18-24 (OR = 2.4, p = 0.014), illiteracy (OR = 1.9, p = 0.033), having never been married (OR = 2.6, p = 0.007), a main source of income of crime/begging (OR = 3.1, p = 0.019), a duration of injecting drug use greater than 20 years (OR = 3.4, p = 0.035) and suicidal ideation (OR = 1.7, p = 0.048). Male-to-male sex was associated with psychosocial vulnerability, including a longer history of injecting drug use, suicidal ideation and socio-economic disadvantage. Given the extent of overlapping HIV risk behaviours, HIV programs for PWID would benefit from a strong focus on prevention of sexual HIV transmission, especially among male injectors who also have sex with other men.

    "A human capital framework is utilized to examine the economic progress of nine nationality groups of foreign workers [in Kuwait] using data from the 1983 national Labor Survey. The sources of earnings' variations of particular interest to us included different degrees of education and experience transferability, occupational affiliation and ethnic background. In general, the results derived from the analysis suggest that 1) foreign workers achieve a discernible economic progress as their residence lengthens; 2) the rate of economic progress varies depending on worker's education, home and Kuwait-specific experience, occupational status and ethnic background; and 3) about one third of the earnings inequality is due to unexplained factors including discrimination." excerpt

    In order to assess whether the law has an impact on the delivery of health promotion services to sex workers, we compared health promotion programs in three Australian cities with different prostitution laws. The cities were Melbourne (brothels legalized if licensed, unlicensed brothels criminalized), Perth (criminalization of all forms of sex work) and Sydney (sex work largely decriminalized, without licensing). We interviewed key informants and gave questionnaires to representative samples of female sex workers in urban brothels. Despite the different laws, each city had a thriving and diverse sex industry and a government-funded sex worker health promotion program with shopfront, phone, online and outreach facilities. The Sydney program was the only one run by a community-based organisation and the only program employing multi-lingual staff with evening outreach to all brothels. The Melbourne program did not service the unlicensed sector, while the Perth program accessed the minority of brothels by invitation only. More Sydney workers reported a sexual health centre as a source of safer sex training and information (Sydney 52% v Melbourne 33% and Perth 35%; plegal context appeared to affect the conduct of health promotion programs targeting the sex industry. Brothel licensing and police-controlled illegal brothels can result in the unlicensed sector being isolated from peer-education and support. © 2010 The Authors.

    Female sex workers (FSWs) aged ≥18 years without known HIV infection living in Tijuana and Ciudad Juarez who had recent unprotected sex with clients underwent interviews and testing for Chlamydia and gonorrhea using nucleic acid amplification. Correlates of each infection were identified with logistic regression. Among 798 FSWs, prevalence of Chlamydia and gonorrhea was 13.0% and 6.4%. Factors independently associated with Chlamydia were being younger, working in Tijuana versus Ciudad Juarez, and recent methamphetamine injection. Factors independently associated with gonorrhea were working in Tijuana versus Ciudad Juarez, using illegal drugs before or during sex, and having a recent male partner who injects drugs. Chlamydia and gonorrhea infection were more closely associated with FSWs’ drug use behaviors and that of their sexual partners than with sexual behaviors. Prevention should focus on subgroups of FSWs and their partners who use methamphetamine and who inject drugs. PMID:20852194

    In this study, the annual cycle of the gonadal steroids testosterone (T), 11-ketotestosterone (11-KT), 17β-oestradiol (E2) and 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) was determined using radioimmunoassay and then compared, for XY males (n=35) and sex-reversed XX males (n=27) rainbow trout, to establish possible endocrinology differences. Both in XY males and sex-reversed XX males, significant correlation was shown between body weight and T (r=0.5046 and 0.34078, respectively; psex-reversed XX males were similar and showed an intense seasonal variation. The highest levels for T and 11-KT were detected from December to April with a peak in January (51.67 ± 5.11 and 61.95 ± 4.25 ng/ml, for XY males and 57.1 ± 5.82 and 59.27 ± 4.84 ng/ml, respectively, for XX males). In addition, there was a positive correlation (psex-reversed XX males (r=0.6019). Concentrations of DHP in XY males also showed seasonal variation with a peak in February (25.18 ± 12.99 ng/ml). However, DHP levels in sex-reversed XX males were undetectable (sex-reversed XX males were similar to those observed in XY males. The only difference in the annual gonadal steroid cycle between XY and sex-reversed XX males was in the DHP profile. © 2009 Blackwell Verlag GmbH.

    For many years, the sex industry in Hong Kong has appeared to be an integral and ever-expanding component of the city's sociocultural and economic structure. Accordingly, the physical and psychological health of sex workers is becoming an increasing concern for the workers themselves, the public, and government policy. A cross-sectional survey on the quality of life (World Health Organization Quality of Life [WHOQOL]) of female sex workers (FSWs) in Hong Kong was used to investigate the physical and psychological well-being of street FSWs, and the results were compared with those of non-sex-working Hong Kong women after adjusting for age, educational level, marital status, and health status. The 89 FSWs surveyed scored significantly lower on QOL--WHOQOL-BREF (HK)--measures compared with the non-sex-working women. One common aspect among these sex workers was their negative view of themselves and of life. Many sex workers were at risk of being abused while at work, and many women worked without legal protection. Most of the women surveyed engaged in sex work to support their families. Because their income was often insufficient, some of their needs, especially those concerning health, were often neglected. The low WHOQOL-BREF (HK) scores in FSWs indicate feelings of helplessness and entrapment, which may well result in detrimental effects on sex workers' health, self-esteem, and confidence when asserting their basic rights, such as access to healthcare and safety. The conclusion highlights the vulnerability of this population to apparent weaknesses in Hong Kong's current healthcare system.

    In Bangalore, new HIV infections of female sex workers and men who have sex with men continue to occur, despite high condom use. Pre-exposure prophylaxis (PrEP) has high anti-HIV efficacy for men who have sex with men. PrEP demonstration projects are underway amongst Indian female sex workers. We estimated the impact and efficiency of prioritizing PrEP to female sex workers and/or men who have sex with men in Bangalore. A mathematical model of HIV transmission and treatment for female sex workers, clients, men who have sex with men and low-risk groups was parameterized and fitted to Bangalore data. The proportion of transmission attributable (population attributable fraction) to commercial sex and sex between men was calculated. PrEP impact (infections averted, life-years gained) and efficiency (life-years gained/infections averted per 100 person-years on PrEP) were estimated for different levels of PrEP adherence, coverage and prioritization strategies (female sex workers, high-risk men who have sex with men, both female sex workers and high-risk men who have sex with men, or female sex workers with lower condom use), under current conditions and in a scenario with lower baseline condom use amongst key populations. Population attributable fractions for commercial sex and sex between men have declined over time, and they are predicted to account for 19% of all new infections between 2016 and 2025. PrEP could prevent a substantial proportion of infections amongst female sex workers and men who have sex with men in this setting (23%/27% over 5/10 years, with 60% coverage and 50% adherence), which could avert 2.9%/4.3% of infections over 5/10 years in the whole Bangalore population. Impact and efficiency in the whole population was greater if female sex workers were prioritized. Efficiency increased, but impact decreased, if only female sex workers with lower condom use were given PrEP. Greater impact and efficiency was predicted for the scenario with lower condom use

    This study examines the relationship between alcohol use, HIV status, and condom use among female sex workers in Nagaland, India. We analyzed data from a cross-sectional survey undertaken in 2009, using descriptive and multivariate statistics. Out of 417 female sex workers, one-fifth used alcohol daily and one-tenth were HIV-positive. HIV-positive female sex workers were more likely than HIV-negative female sex workers to consume alcohol daily (30.2% vs. 18.0%). HIV-positive daily alcohol users reported lower condom use at last sex with regular clients compared to HIV-positive non-daily alcohol users (46.2% vs. 79.3%), a relationship not evident among HIV-negative female sex workers. There is a need to promote awareness of synergies between alcohol use and HIV, and to screen for problematic alcohol use among female sex workers in order to reduce the spread of HIV.

    The Criminal Code of Canada prohibits certain aspects of sex work: the keeping of a common bawdy-house, living off the avails of prostitution and communicating for the purposes of prostitution in a public place. These legal constraints impede sex workers' ability to practise their profession safely and without risk to their bodily integrity; they also impair their personal autonomy and can lead to their stigmatization. Bedford v. Canada is a groundbreaking case, since the applicants and intervening organizations seek to overturn aspects of Canadian law that specifically put the health and human rights of sex workers at risk.

    Full Text Available INTRODUCTION: Sex workers (SW clients represent a bridge population for HIV transmission from high risk to low risk general population. MATERIALS AND METHODS: A cross-sectional anonymous telephone survey was carried out at the AIDS and Sexually Transmitted Infections Helpline of National Institute of Health in Italy. The questionnaire was proposed on a voluntary basis to a sample of 119 subjects from helpline users. RESULTS: The 119 participants were all males, aged between 19 and 59 years and mostly accessed female prostitutes. Vaginal intercourses with SW were more frequently reported, followed by passive oral, active oral sex and active anal intercourses. Cumulatively, 86.6% and 84.6% of vaginal and anal intercourses were respectively reported as regularly protected by condom. DISCUSSION: The telephone interview allowed an eased access, a high response rate and a standardised evaluation of questions CONCLUSIONS: It is necessary a constant monitoring of the characteristics, behaviour, risk perception and testing of SW clients in Italian and other populations.

    Full Text Available Objectives In most countries around the world, sex work is an illegal activity. Female sex workers (FSWs in Iran hide their identities, and they are known to be a hard-to-reach population. Despite free access to HIV testing, fewer than half of FSWs receive HIV testing. The purpose of this study was to characterize the reasons for which FSWs do not seek testing at drop-in centers (DICs and voluntary counseling and testing (VCT centers in Iran. Methods A qualitative study was conducted in 2016. The participants were 24 FSWs who received services at VCT centers and DICs for vulnerable females in the north of Iran and 9 males who were the clients of FSWs. In this study, we made use of purposive sampling and carried out a thematic analysis. Results We found 4 major and 6 minor themes. The major themes were: fear of being infected (with HIV, stigma, indifference, and knowledge. Conclusions Despite the significant efforts made by the government of Iran to establish and expand DICs for vulnerable females, the number of FSWs receiving services at these centers has not been very considerable. Consequently, by introducing and implementing training programs for peer groups, it may be possible to take steps toward establishing strategic programs for the control and prevention of HIV/AIDS.

    To assess the prevalence of undiagnosed cardiovascular disease (CVD) in a cohort of male steelworkers in South Wales, UK. Male steel industry workers (n = 221) with no prior diagnosis of CVD or diabetes accepted a CVD risk assessment within the work environment. Demographic, anthropometric, family, and medical histories were all recorded and capillary blood samples obtained. The 10-year CVD risk was predicted using the QRISK2-2012 algorithm. Up to 81.5% of workers were either overweight or obese. More than 20% of workers were found to have diastolic hypertension, high total cholesterol, and/or a total cholesterol/high-density lipoprotein ratio of six or more. Over one quarter of workers assessed had an increased 10-year CVD risk. Despite a physically demanding occupation, risk assessment in the workplace uncovered significant occult factors in CVD risk in a sample of male heavy industry workers.

One hundred and twenty-nine married male tanshin funin workers in their 40s and 50s and as many matched workers living with their family (regular workers) participated. Fewer tanshin funin workers took breakfast everyday (OR=3.3, phealth problems, namely headache (OR=4.7, p=0.013) and gastric/duodenal ulcers (OR=8.7, pmental stress were thus important effects of tanshin funin. Tanshin funin workers should be provided with health and lifestyle education programs and mental health care before and during tanshin funin. Doctors and nurses in the healthcare departments of companies should play a leading role.

    Full Text Available BACKGROUND: Clients of sex workers represent a relevant target for interventions aimed at the prevention of HIV and sexually transmitted infections (STIs. Within prevention strategies, the AIDS and sexually transmitted infections helpline (Telefono Verde AIDS/ IST, TVA-IST of National Institute of Health in Italy has provided, since 1987, specific information and counselling interventions. AIM: The present study reports data on anagraphical characteristics and behaviours of clients of sex workers, anonymously reported at TVA-IST in the period 1987-2010. DISCUSSION: Among 95 149 phone calls (14% of the total considered 99.5% came from males, over 80% aged under 37 years and prevalently from Northern Italy. Among sexual behaviours, unprotected sexual intercourses were reported in the 26% of the calls. Subjects under 27 years reported a higher frequency of unprotected anal intercourse, while they used protection with oral and vaginal intercourses in a greater extent than older ones. Due to differential behaviours within clients of sex workers, specific informative strategies for this targeted population should adequately consider age-related differences.

    We reviewed evidence from more than 800 studies and reports on the burden and HIV implications of human rights violations against sex workers. Published research documents widespread abuses of human rights perpetrated by both state and non-state actors. Such violations directly and indirectly increase HIV susceptibility, and undermine effective HIV-prevention and intervention efforts. Violations include homicide; physical and sexual violence, from law enforcement, clients, and intimate partners; unlawful arrest and detention; discrimination in accessing health services; and forced HIV testing. Abuses occur across all policy regimes, although most profoundly where sex work is criminalised through punitive law. Protection of sex workers is essential to respect, protect, and meet their human rights, and to improve their health and wellbeing. Research findings affirm the value of rights-based HIV responses for sex workers, and underscore the obligation of states to uphold the rights of this marginalised population.

    To analyze the characteristics of risky behaviors among different age groups of HIV positive female sex workers, and to explore the strengthening of their management. From January to June 2014, 22 814 female sex workers were investigated and tested HIV in 117 sentinel surveillance sites in Yunnan Province, and 181 were confirmed to be HIV antibody positive, who accepted questionnaire surveys. According to the age, the participants were divided into the HIV/AIDS and related risk behaviors characteristics of the two groups were obtained via questionnaire surveys among 181 HIV positive female sex workers, and in-depth qualitative interviews were conducted from among 12 HIV positive sex workers. HIV antibody positive rate was 0.8% (181), the age of the 181 subjects were (35.83 ± 9.17) years old, 76 cases (42.0%) were HIV, the proportion of AIDS awareness was 95.6% (173); the proportion of drug use among ≥ 35 years old age group was 51.4% (54), which was higher than that in HIV counseling and testing in the past year. The proportion of continuing to engage in sexual services over 5 years after HIV infection was 48.5% (51/105) and the proportion of receiving antiretroviral treatment was 69.5% (73/105) in ≥ 35 years old age group, which were higher than those in the HIV positive female sex workers found that regular clients, not consistent use of condoms were the main cause of no condom use. Economic and livelihood factors are important reasons for continuing to engage in sexual services among HIV positive sex workers. HIV positive sex workers still have high risk behaviors including continuing to engage in commercial sexual service and no condom use after knowing their HIV infection status, and the proportion of using drugs in the ≥ 35 years old group was higher than that in < 35 years old group.

  15. HIV risk perception, risk behavior, and seroprevalence among female commercial sex workers in Georgetown, Guyana

    Full Text Available A study of 108 female sex workers engaged in prostitution in Georgetown, Guyana, was made in April 1993. Based on interviews and procurement of blood samples, the study investigated relationships between HIV seroprevalences and AIDS knowledge, risk behaviors, client characteristics, and condom use. Street-walkers--as distinct from sex workers in bars, hotels, and Port Georgetown--tended to charge less, be worse off socioeconomically, and have clients who were similarly disadvantaged; they were therefore classified as belonging to a "lower" socioeconomic stratum, while the other workers were classified as belonging to a "higher" stratum. The overall HIV seroprevalence found among the sex workers was 25% (95%CI: 17%-33%. But the 50 subjects in the lower stratum had a relatively high seroprevalence (42%, as compared to 10% among those in the higher stratum, accounting for 21 of the 27 HIV-seropositive subjects. Reported patterns of client origins (Guyanese or foreign, worker willingness to have sex without a condom, and condom use by clients differed by stratum. Participants in the higher stratum were more disposed to having sex without a condom. The workers' knowledge of what causes AIDS and how HIV is transmitted was low in both strata; substantial numbers of workers said they had contracted a sexually transmitted disease within the past two years or were users of illicit drugs. Condom use is reportedly less common among Guyanese than foreign clients, suggesting a greater risk of contracting HIV from Guyanese clients or infecting Guyanese clients with it. The HIV seroprevalence among workers who said they had only Guyanese clients was statistically greater than the rate among those who said they had only foreign clients. The HIV seroprevalence among those reporting more than five clients per week was statistically greater than among those reporting fewer. HIV seropositivity was relatively high among the 12 workers who said they used cocaine

    In 1998, researchers in Burkina Faso enrolled 300 women more or less involved in commercial sex work in an open cohort to determine whether adequate management of their sexually transmitted infections and exposure to well-designed, well-delivered, and plentiful communication for behaviour change (CBC) might reduce their vulnerability to HIV. In 2000, they observed that the non-professional sex workers (occasional or clandestine sex workers) were more difficult to reach, to mobilize and to keep involved in the project's different activities. This group was also infected at the same or higher rates than professional sex workers because they did not use condoms routinely. To accomplish the project objectives, they therefore chose to recruit more non-professional sex workers in the new cohort of 700 women. This social-anthropological study was conducted to help them to enrol young clandestine sex workers. The overall objective of this study was to understand the life of this category of sex workers and to identify strategic actors to reach them. Using a qualitative method, social anthropologists reviewed literature, identified and geo-referenced all local places suitable to encountering these women, obtained life stories from some of them and interviewed key informants and participants in the field. The results showed that in Bobo-Dioulasso (Burkina Faso): - most young women who are clandestine sex workers are Burkinabe, and girls entering the sex trade are increasingly young and increasingly uneducated; - most of them come from families with low capital (financial, cultural, or social). The parents' socioeconomic status (contextual poverty) results in unmet financial needs, which in turn exposes them to starting work early, including commercial sex work; - of all the income-generating activities available to unskilled young girls, commercial sex work is one of the most profitable and easily accessible; - in the three-fold context of an HIV epidemic, poverty, and

    Male clients of female sex workers (FSWs) are epidemiologically important because they can form bridge groups linking high- and low-risk subpopulations. However, because male clients are hard to locate, they are not frequently studied. Recent research emphasizes searching for high-risk behavior groups in locales where new sexual partnerships form and the threat of HIV transmission is high. Sub-Saharan Africa public drinking venues satisfy these criteria. Accordingly, this study developed and implemented a rapid assessment methodology to survey men in bars throughout the large informal settlement of Kibera, Nairobi, Kenya, with the goal of delineating cultural and economic rationales associated with male participation in commercial sex. The study sample consisted of 220 male patrons of 110 bars located throughout Kibera's 11 communities. Logistic regression analysis incorporating a modified Reasoned Action Model indicated that a social norm condoning commercial sex among male peers and the cultural belief that men should practice sex before marriage support commercial sex involvement. Conversely, lacking money to drink and/or pay for sexual services were barriers to male commercial sex involvement. Results are interpreted in light of possible harm reduction programs focusing on FSWs' male clients.

    China has seen a proliferation of entertainment centres that are frequented by business people. Employees at these centres often are young, female rural-to-urban migrants who may be vulnerable to sexual violence and exploitation. Data for this study were collected using a self-administered survey among male and female employees in two high-end entertainment centres in Changsha, Hunan Province, China. We used logistic regression to examine predictors of violent and potentially exploitative experiences (partner violence, forced sex and transactional sex). Predictors included gender, ever having a same-sex partner, migration variables and employment characteristics. Participants reported high levels of partner violence (16.0% ever and 9.0% in the past 3 months) and forced sex (13.9% ever and 5.5% in the past 3 months). Nineteen percent reported sex work in the past 3 months. In the multivariate regressions, ever having had a same-sex partner was associated with higher odds of ever having experienced partner violence (odds ratio (OR)=7.8, Pgender nor migration status was associated with any of the outcomes. High-end entertainment centre workers in China are at risk for sexual violence and should be targeted with employment-based interventions.

    Commercial sex represents a critical context for HIV transmission within India and elsewhere. Despite research and programmatic attention to commercial sex workers (CSWs), less is known concerning the male CSW clients considered a bridge population for HIV transmission to the general population and thought to drive demand for the sex trafficking of women and girls. The current study assesses the prevalence of past year CSW contact, condom nonuse therein, and associations with demographic characteristics and gendered attitudes among a national sample of Indian men. The nationally representative Indian National Family Health Survey-3 was conducted across all Indian states in 2005-2006; the current sample was limited to 46,961 sexually active men. Analyses calculated the prevalence of past year CSW contact and inconsistent condom use; adjusted logistic regression models were used to evaluate associations of demographic characteristics, sexual entitlement and justification of wife abuse with past year CSW contact, and inconsistent condom use. Approximately 1 in 100 Indian men (0.9%) reported past year CSW contact; over half of such men reported inconsistent condom use with CSWs. CSW contact was most common among men ages 15-24 (3.6%) and never married men (9.9%). Men's CSW contact related to higher levels of sexual entitlement (adjusted odds ratio = 1.64; 95% confidence interval 1.24 to 2.17) and justification of violence against wives (adjusted odds ratio = 1.41; 95% confidence interval: 1.03 to 1.93). Men's past year CSW contact was concentrated among young and unmarried Indian men; condom nonuse with CSWs was common. Traditional gender ideologies seemed to support men's CSW contact, bolstering consideration of this behavior as a gendered form of HIV risk. Findings provide direction for interventions to reduce men's CSW contact in the Indian context by describing high-risk subpopulations and indicating that gender ideologies should be addressed.

  3. The representation of sex workers in South African media: Danger, morals and human rights

    Full Text Available The ideological construct of gender typically positions women below men, and “others” certain types of women even more, especially those distinguished from idealised femininity by aspects of their sexuality. This paper explores the representation of sex work and sex workers in the South African media in 2009 and 2010, a time during which there was an increase in news coverage of sex work during the 2010 FIFA World Cup. Analysis of the two data sets revealed that sex work is still often perceived as immoral and dangerous, and that sex workers – overwhelmingly represented as women – are criminalised for their actions while client agency is largely obscured, which is in line with previous studies of South African newspapers. However, a strong liberal representation of sex workers was also found in one data set, which advocates the decriminalisation of sex work in the context of human rights. The use of the term “sex work” and its derivatives, rather than “prostitution”, was found to index this progressive stance.

    Fabiana Schuelter Trevisol

    Full Text Available We examined HIV frequency and probable risk factors among female sex workers in the port city of Imbituba, Southern Brazil. From December 2003 through February 2004, 90 female sex workers were interviewed in order to investigate demographic, socioeconomic and behavioral variables related to HIV infection. A blood sample of each woman was also collected to test for HIV antibodies. Six (6.7% of the sex workers were HIV-positive; the significantly-correlated risk factors were the daily number of clients (p = 0.008, the use of inhaled illicit drugs by the sex workers (P = 0.053 and by their clients (p = 0.005, and the lack of condom use in sexual relations (p = 0.015. The HIV infection rate in these sex workers was higher than that in the general population and similar to that found in other studies made with Brazilian populations presenting the same characteristics. This highlights the need for preventative measures, especially in this port area, in order to reduce transmission and to deter the introduction and dissemination of HIV.

    The current study aimed to identify the sources of HIV prevention information for female sex workers in Beijing and assess the associations between levels of mass media exposure of HIV/AIDS prevention information and HIV/AIDS knowledge as well as condom use-related attitudes, beliefs, and behaviors. Cross-sectional data were collected from 359 female sex workers in Beijing, China. Chi-square tests and one-way ANOVA tests were employed. Female sex workers sampled in Beijing were more likely to obtain HIV/AIDS prevention information from television and street posters than radio and the Internet. However, a higher level of exposure to and a lasting impression on online information were significantly associated with a higher level of condom use self-efficacy and more consistent condom use among the participants. Exposure to HIV/AIDS prevention information delivered by radio, street posters, and the Internet was found to be associated with sexual communication about HIV or condom use with sexual partners. Overall, this study provides preliminary evidence of the utility of various mass media outlets in delivering HIV/AIDS prevention information among female sex workers in China. Future studies are needed to systematically examine the effectiveness of mass media-based prevention education on HIV/AIDS related attitudes and behaviors among female sex workers and other populations in China.

    This study aims to quantify the prevalence of work-related musculoskeletal disorders (MSDs) and risks among male kitchen workers in the catering industry. Data were collected with the help of the Nordic musculoskeletal questionnaire and by direct observations. In total, 114 male kitchen workers from various hostels of a college in South India were considered for this study. The average age and mean years of employment of the workers are 26.4 (SD 7.7) and 7.8 respectively. The statistical analysis carried out reveals that 67.5% of male kitchen workers reported MSDs during the past 12 months. The highest prevalence rate has been found in the lower back (65.8%) and shoulder region (62.3%). Among different categories of kitchen work analyzed, it is evident that chief cooks suffer more from MSDs (79.2%) than assistant cooks (74.3%) and kitchen aides (30.0%). Workers in the older group, i.e., ≥ 41 years, and workers with 6-10 years of experience suffer with higher risk of MSDs, i.e., 93.9% and 87.5%, respectively. The male kitchen workers who participated in this research were found to possess both MSDs and ergonomic hazards.

    Full Text Available Abstract Background This paper examines the differences in demographics, drug use patterns and self reported risk behaviours between regular injecting drug users (IDU who report engaging in sex work for money or drugs and regular injecting drug users who do not. Methods Cross sectional data collected from regular IDU interviewed as part of the New South Wales (NSW Illicit Drug Reporting System (IDRS in 2003 were analysed. Results IDU who reported engaging in sex work were more likely to be female, and identify as being of Aboriginal and/or Torres Strait Islander descent. They initiated injecting drug use at a significantly younger age and were more likely to report injection related problems than IDU who had not engaged in sex work. There were no differences in the drug classes used, but findings suggested that the sex workers tended to be more frequent users of crystalline methamphetamine (ice and benzodiazepines. Conclusion The similarities between these groups were more striking than the differences. Further research, examining a larger sample is needed to clarify whether injecting drug users who are sex workers have heavier use patterns.

    Social marginalization and criminalization create health and safety risks for sex workers and reduce their access to health promotion and prevention services compared to the general population. Community empowerment-based interventions that prioritize the engagement of sex workers show promising results. Peer-to-peer interventions, wherein sex workers act as educators of their colleagues, managers, clients and romantic partners, foster community mobilization and critical consciousness among sex workers and equip them to exercise agency in their work and personal lives. A pilot peer health education program was developed and implemented, with and for sex workers in one urban centre in Canada. To explore how the training program contributed to community empowerment and transformative learning among participants, the authors conducted qualitative interviews, asked participants to keep personal journals and to fill out feedback forms after each session. Thematic analysis was conducted on these three data sources, with emerging themes identified, organized and presented in the findings. Five themes emerged from the analysis. Our findings show that the pilot program led to reduced internalized stigma and increased self-esteem in participants. Participants' critical consciousness increased concerning issues of diversity in cultural background, sexual orientation, work experiences and gender identity. Participants gained knowledge about how sex work stigma is enacted and perpetuated. They also became increasingly comfortable challenging negative judgments from others, including frontline service providers. Participants were encouraged to actively shape the training program, which fostered positive relationships and solidarity among them, as well as with colleagues in their social network and with the local sex worker organization housing the program. Resources were also mobilized within the sex worker community through skills building and knowledge acquisition. The peer

    The Ayoreo population constitutes one of Bolivia's most vulnerable ethnic groups in terms of HIV/AIDS. Being a woman, indigenous, and a sex worker signifies belonging to a high-risk group. The aim of this study is to explore the Ayoreo sex workers' and health agents' perceptions of HIV/AIDS prevention programs in order to identify variables that could influence their success or failure. This study used an ethnographic methodology that included participant observation and semistructured interviews. In the data collection, participant observation and semistructured interviews with sex workers and key informants were conducted. Three themes emerged from the inductive data analysis: health prevention efforts, cultural inadequacy of prevention programs, and the eventuality of interventions. We conclude that nursing can develop culturally-adequate HIV/AIDS prevention interventions and programs as well as promote health within these populations. © The Author(s) 2014.

    Full Text Available The study objective is to examine the effects of age and sex on the association between various obesity parameters and lipid profile. The measurements of whole body obesity (body fat, body fat % and BMI, abdominal obesity (waist to hip ratio, waist to thigh ratio and waist circumference and lipid profile (HDL, LDL, VLDL, total cholesterol and triglyceride were performed on 112 telecom workers in Palembang (84 men and 28 women, age 25, 35, 45, and 55 years. All lipid parameters results depend on sex and age of subjects. The association between obesity assessments and HDL or LDL was independent of sex and age of subjects, whereas the association between obesity assessments and total cholesterol, VLDL and triglyceride is dependent on sex and age of subjects. Abdominal obesity has greater effect on VLDL and triglyceride levels than on other lipid parameters. Whole body obesity has equal effects on all lipid parameters. When comparing results of male and female subjects, obesity measurements and lipid profile association is stronger in male subjects of almost all age groups. The exception is a stronger association between abdominal obesity and VLDL or triglyceride levels in 45 years old female subjects. Obesity measurements and VLDL or triglyceride level association is independent of age, whereas obesity and total cholesterol association is stronger in younger subjects.

    Full Text Available BACKGROUND: Sex workers in China continue to engage in unprotected sex acts that put them at risk for contracting HIV (Human Immunodeficiency Virus and other STIs (Sexually Transmitted Infections. The purpose of this study was to explore women's work history, the context of sex work, condom use, HIV testing services, and potential barriers to condom use in a sample of FSWs (female sex workers in Guangzhou, China. METHODOLOGY/PRINCIPAL FINDINGS: In-depth, semi-structured, face-to-face interviews were conducted with 24 FSWs in Guangzhou, China. Informants were recruited using a purposive sampling technique. Qualitative data were coded and analyzed using NVivo 8.0. The majority of respondents were internal economic migrants who had entered the sex industry in pursuit of greater financial reward. Most women in the study were married or had steady boyfriends, and were young, with secondary education and limited knowledge about HIV and STIs. Most were not satisfied with their current living conditions and expressed a desire to leave the sex industry. Women reported that they were more likely to use condoms during sex acts with commercial partners than with non-commercial partners. The potential stigma of being seen as a sex worker prevented many from accessing HIV testing. Three key factors put these FSWs at risk for HIV and STIs: unreasonable trust toward clients, stereotypes and assumptions about customers, and financial incentives. CONCLUSIONS/SIGNIFICANCE: These findings suggest that social and economic factors play an important role in shaping sexual decision-making among female sex workers in Guangzhou. We argue that greater insight into and attention to these factors could enhance the success of HIV prevention efforts.

    Full Text Available Background: The tendency for female sex workers to seek health care is highly influenced by physician attitudes and behavior. By identifying medical students' attitudes toward female sex workers and assessing their knowledge of barriers to seeking care, we can focus medical training and advocacy efforts to increase access to care and improve public health outcomes. Methods: In this cross-sectional study, medical students from various countries were invited to participate in an online survey with close-ended questions and Likert scale statements. Responses were quantified and knowledge and attitude scores were assigned based on knowledge of barriers to seeking care and agreement with positive and negative attitude statements. Results: A total of 292 medical students from 56 countries completed the survey, of whom 98.3% agreed that it will be their job to provide treatment to patients regardless of occupation. Self-identified religious students conveyed more negative attitudes toward female sex workers compared to those who did not identify themselves as religious (p<0.001. Students intending to practice in countries where prostitution is legal conveyed more positive attitudes compared to those intending to practice in countries where prostitution is illegal (p<0.001. Conclusion: Medical students largely agreed on the importance of providing care to female sex workers as a vulnerable group. In addition to addressing knowledge gaps in medical education, more localized studies are needed to understand the religious and legal influences on attitudes toward female sex workers. Such information can help focus the efforts in both medical education and communication training to achieve the desired behavioral impacts, reconciling the future generations of health care providers with the needs of female sex workers.

    To assess the prevalence of smoking and associated variables in female sex workers (FSWs). This was a quantitative cross-sectional study involving FSWs in the city of Botucatu, Brazil, who completed a sociodemographic questionnaire, including data regarding smoking status, motivational stage of change, and degree of nicotine dependence, as well as the Perceived Stress Scale and the Hospital Anxiety and Depression Scale. We included 83 FSWs. The mean age was 26.8 years. Among the participants, 58 (69.8%) had at least a high school education, only 26 (31.3%) resided in the city of Botucatu, 59 (71.1%) were smokers, 5 (6.0%) were former smokers, 74 (89.2%) regularly consumed alcohol, and 43 (51.8%) used illicit drugs. The majority of the women were classified as having an intermediate stress level, and 51 (61.4%) were classified as having possible or probable anxiety, whereas depression was found to be improbable in 57 (68.7%). The level of nicotine dependence was high among the smokers, the majority of whom showed no intention to quit smoking. Smoking was associated with illicit drug use (p = 0.0271) and with alcohol consumption (p = 0.0001), although not with the levels of stress, anxiety, or depression; nor was the age at smoking initiation associated with the length of time as an FSW (p = 0.4651). The prevalence of smoking among the FSWs evaluated here was much higher than the 8.3% reported for the overall female population of Brazil. Our findings show that FSWs are exposed to various risk factors inherent to their profession. Therefore, harm reduction is an important strategy to be adopted.

    Public health regulations practices surrounding sex work and their enforcement can have unintended consequences for HIV and sexually transmitted infection (STI) prevention and care among sex workers. This analysis was based on qualitative in-depth (n = 33) and focus groups interviews (n = 20) conducted with migrant female sex workers in Tecún Umán and Quetzaltenango, Guatemala, and explored the implementation of sex work regulations and related consequences for HIV prevention and care among migrant sex workers. Sex work regulations were found to have health-related benefits (e.g., access to HIV/STI testing) as well as negative impacts, such as abuse by police and harassment, detention/deportation of migrant sex workers. Whereas public health regulations may improve access to HIV/STI testing, their implementation may inadvertently jeopardize sex workers' health through unintended negative consequences. Non-coercive, evidence-based public health and sex work policies and programs are needed to expand access to HIV/STI prevention and care among migrant sex workers, while protecting their dignity and human rights.

    This investigation compared Dutch same-sex parent and different-sex parent households on children's psychological well-being, parenting stress, and support in child rearing. It was also assessed whether associations among children's well-being, parenting stress, and support in child rearing were different in the two household types. Data were based on a nationally representative survey (N = 25,250). Matching was used to enhance similarity in background characteristics between both types of families. Parental and child characteristics were matched for 43 female same-sex parent, 52 male same-sex parent, and 95 different-sex parent households with offspring between 5 and 18 years old. No significant differences were found on children's well-being, problems in the parent-child relationship, being worried about the child, or the use of formal and informal support between mothers in same-sex and different-sex parent households or for fathers in same-sex and different-sex parent households. Regarding perceived confidence in child rearing, fathers in same-sex parent households and mothers in different-sex parent households felt less competent than their counterparts. Neither the associations between children's well-being and the predictors (parenting stress variables) nor those between support and the predictors (parenting stress and children's well-being) differed along household type. In this population-based study, the similarity in child outcomes regardless of household type confirms the results of prior investigations based on convenience samples. These findings are pertinent to family therapists, practitioners, court officials, and policymakers who seek information on parenting experiences and child outcomes in female and male same-sex parent families. © 2017 Family Process Institute.

    Migrant sex workers are often highly marginalized and disproportionately experience health and social inequities, including high prevalence of HIV, sexually transmitted infections, and human rights violations. In recent years, research involving migrant sex workers has increased, yet many knowledge gaps remain regarding how best to protect research participant rights and welfare. Our objective was to identify key challenges and opportunities related to the responsible conduct of HIV research with migrant sex workers. Focus groups and interviews conducted with 33 female sex workers ≥18 years old at the Guatemala-Mexico border from June 2013-February 2014 were analyzed. Participants were recruited through community outreach by a local HIV prevention organization to sex work establishments such as bars, hotels, street corners, and truck stops.

    Full Text Available Migrant sex workers are often highly marginalized and disproportionately experience health and social inequities, including high prevalence of HIV, sexually transmitted infections, and human rights violations. In recent years, research involving migrant sex workers has increased, yet many knowledge gaps remain regarding how best to protect research participant rights and welfare. Our objective was to identify key challenges and opportunities related to the responsible conduct of HIV research with migrant sex workers.Focus groups and interviews conducted with 33 female sex workers ≥18 years old at the Guatemala-Mexico border from June 2013-February 2014 were analyzed. Participants were recruited through community outreach by a local HIV prevention organization to sex work establishments such as bars, hotels, street corners, and truck stops.Key themes influencing research engagement for migrant sex workers included researcher mistrust and fear related to research participation, rooted in the social isolation frequently faced by recent migrants; intersecting concerns related to immigration status, fear of criminalization, and compliance with sex work regulations; and perceived benefits and risks of HIV/STI testing for migrants (e.g., immigration implications, stigma represent potential barriers and opportunities for the responsible conduct of research involving migrant sex workers.Results highlight the intersection between the human rights vulnerabilities of migrant sex workers and barriers to research participation, including social isolation of migrants and policy/legal barriers related to immigration and sex work.

    In social insects, the postembryonic development of individuals exhibits strong phenotypic plasticity in response to the environment, thus generating the caste system. Different from eusocial Hymenoptera, in which queens dominate reproduction and inhibit worker fertility, the primary reproductive caste in termites (kings and queens) can be replaced by neotenic reproductives derived from functionally sterile individuals. Feedback regulation of nestmate differentiation into reproductives has been suggested, but the sex specificity remains inconclusive. In the eastern subterranean termite, Reticulitermes flavipes, we tested the hypothesis that neotenic reproductives regulate worker-reproductive transition in a sex-specific manner. With this R. flavipes system, we demonstrate a sex-specific regulatory mechanism with both inhibitory and stimulatory functions. Neotenics inhibit workers of the same sex from differentiating into additional reproductives but stimulate workers of the opposite sex to undergo this transition. Furthermore, this process is not affected by the presence of soldiers. Our results highlight the reproductive plasticity of termites in response to social cues and provide insights into the regulation of reproductive division of labor in a hemimetabolous social insect.

    Full Text Available This article looks at the way sex workers in Córdoba, Argentina, have dealt with legal marginalization, focusing on their understandings and associated practices of resistance. Sex workers position in law shows the group is on the margins of law, which means that their activity is not considered to be legal but is not illegal either. Since 2000 a group of sex workers started to organize to stop the constant detentions and humiliations by police officers. The organization called AMMAR (Asociación de Mujeres Meretrices Argentinas implied a major shift from an oppression of consciousness to a consciousness of oppression, modifying in this process the terms of their resistance from mere tactics of survival to a struggle for redefinition of their position in law and society. This article firstly explores the idea of margins of law, consciousness, power and resistance, and also describes the regulation of sex work in the city of Córdoba; secondly, it refers to sex workers experiences, perceptions and practices of resistance before the organization in relation to the police, the Judiciary, as well as with other institutions, and relates this experiences with their practices of resistance in that period; thirdly, it explains the process of organization and the way it has influenced their reflective awareness and practices of resistance, it describes as well the heterogeneity of understandings regarding law. Lastly, the Conclusion revisits the outcomes and literature to propose final reflections about dealing with the margins of law in everyday life.

    Full Text Available Abstract Background Under the "two countries, one system" policy implemented by China to manage the return of Hong Kong's sovereignty, Hong Kong has maintained a comparatively prosperous economy within the Asian region. This has resulted in an environment which fosters migration from the mainland to Hong Kong, due largely to proximity, higher earning potential, common language, and a relaxing of border control measures. However not all mainland China citizens are equally able to access these new migration schemes and indeed a number of women such as sex workers are either migrating and/or working illegally and without occupational, legal and health protection within Hong Kong. Discussion Female migrant sex workers are exposed to a number of significant threats to their health, however their illegal status contributes to even greater vulnerability. The prevailing discourses which view these women as either "trafficked women" or as "illegal immigrants" do not adequately account for the complex situations which result in such women's employment in Hong Kong's sex industry. Rather, their position can best be understood within the broader frameworks provided by migration literature and the concept of "structural violence". This allows for a greater understanding of the socio-political issues which are systematically denying migrant sex workers adequate access to health care and other opportunities for social advancement. When these issues are taken into account, it becomes clear that the current relevant legislation regarding both immigration and sex work is perpetuating the marginalised and vulnerable status of migrant sex workers. Unless changes are made, structural barriers will remain in place which impede the ability of migrant sex workers to manage their own health needs and status. Conclusion Female migrant sex workers in Hong Kong are extremely vulnerable to a number of occupational health and safety hazards which have significantly

    To examine the popularity of anonymous sex practices among men using the Internet to find male partners for unprotected sex, and how anonymous sex relates to involvement in other HIV-related risk behaviours, and to investigate the factors associated with engaging in anonymous sex. Structured telephone interviews were conducted with men who used the Internet specifically to find male partners for unprotected sex. Random sampling from 16 websites was used to obtain a national sample. The data reported in this paper were based on quantitative interviews collected with a cross-sectional study design. Between January 2008 and May 2009, confidential telephone interviews lasting approximately 1-2 h were completed with 332 men. Participants were paid $35 for their participation. Most of the men (67.4%) liked anonymous sex, and slightly more than half (51.2%) had engaged in the behaviour during the month prior to interview. Involvement in anonymous sex was associated with greater involvement in a variety of human immunodeficiency virus (HIV)-related risk practices, such as illegal drug use, number of sex partners, and amount of unprotected sex. Four factors were associated with having vs not having anonymous sex: (1) being HIV positive; (2) answering all of the HIV-related knowledge questions correctly; (3) deriving greater enjoyment from having sex in public places, such as parks, public toilets, or adult book shops; and (4) greater impulsivity. Seven factors were associated with greater vs lesser involvement in anonymous sex among those practising the behaviour: (1) being involved in a relationship with a long-term partner; (2) liking to have sex in public places; (3) using bareback-oriented websites to identify sex partners; (4) greater impulsivity; (5) low level of condom use self-efficacy; (6) greater knowledge about HIV/acquired immunodeficiency syndrome; and either (7a) severe childhood maltreatment or (7b) Caucasian race. Men in this population often sought

    Men sex workers in Vancouver have largely transitioned from street to online solicitation coinciding with losing "Boystown," the main outdoor sex work stroll for men. This article explores strategies and barriers to increase safety among men and trans sex workers and clients of men in Vancouver, Canada. Qualitative interviews were conducted (2012-2013) with 61 self-identifed men who currently buy and/or sell sex in a community-based research project known as CHAPS (Community Health Assessment of Men Who Purchase and Sell Sex). Drawing on a socioecological framework, thematic analysis of interview transcripts was conducted utilizing ATLAS.ti 7 software among men (39 workers; 8 buyers). Narratives indicate that gentrification and urban planning led to social isolation and loss of social support networks among men in the sex industry. Concurrently, the restructuring of sex work to online increased workers' safety and control. Narratives reveal how the Internet can provide greater opportunities to negotiate terms of sex work and enhanced screening using webcams, reducing risks of violence, stigma, and police harassment for both workers and clients compared with the street. This study highlights how losing Boystown led to a loss of community and solidarity: key protective measures for sex workers. Online solicitation increased workers' capacity to screen prospective clients and prevent violence. Recent legal reforms in Canada to further criminalize sex work raise significant concern for human rights and health of individuals in the sex industry, and point to the critical need to include voices of men and trans sex workers and buyers in policy discussions. © The Author(s) 2016.

    Little is known about the mental health of female sex workers and women living with HIV/AIDS in the Dominican Republic, which impedes HIV prevention, testing, and treatment. This project estimates the prevalence of depression and identifies key contributing factors to this outcome in female sex workers, women living with HIV/AIDS, and a comparison group. Participants were female sex workers (N = 349), women living with HIV/AIDS (N = 213), and a comparison group of HIV-negative women who were not sex workers (N = 314) from the Dominican Republic. Participants completed questionnaires assessing demographic characteristics and depression. Female sex workers and women living with HIV/AIDS completed additional questionnaires ascertaining HIV or sex work-related internalized stigma. Depression was prevalent among female sex workers (70.2%), women living with HIV/AIDS (81.1%), and the comparison group (52.2%). Adjusted logistic regressions showed that internalized stigma was associated with depression for female sex workers (OR = 2.73; 95% CI = 1.95-3.84) and women living with HIV/AIDS (OR = 3.06; 95% CI = 1.86-5.05). Permanent income was associated with this outcome for female sex workers (OR = 0.08; 95% CI = 0.01-0.80) and the comparison group (OR = 0.04; 95% CI = 0.00-0.45).

    How governments should address sex work is a topic of current debate in Rwanda and other countries. Some constituencies propose harsher punishment of sex workers as the cornerstone of an improved policy. We argue that an adequate policy response to sex work in the Rwandan context must prioritize public health and reflect current knowledge of the social determinants of health. This does not imply intensified repression, but a comprehensive agenda of medical and social support to improve sex workers' access to health care, reduce their social isolation, and expand their economic options. Evidence from social epidemiology converges with rights-based arguments in this approach. Recent field interviews with current and former sex workers strengthen the case, while highlighting the need for further social scientific and epidemiological analysis of sex work in Rwanda. Rwanda has implemented some measures that reflect a rights-based perspective in addressing sex work. For example, recent policies seek to expand access to education for girls and support sex workers in the transition to alternative livelihoods. These policies reinforce the model of solidarity-based public health action for which Rwanda has been recognized. Whether such measures can maintain traction in the face of economic austerity and ideological resistance remains to be seen.

    2014-01-01

    Background Public health and human right issues are challenging in low and middle income countries. The main objectives of this paper were to determine the prevalence and factors associated with domestic violence, extramarital sex, and spousal communication among male. Methods A cross-sectional study among 2466 married males in Kathmandu, Nepal was conducted using random sampling method. Adjusted odds ratios (AORs) and 95% confidence intervals (CI) of associated factors were estimated by stepwise backward likelihood ratio method. Results Prevalence of domestic violence was 63.14% (95% CI 61.20-65.05), extramarital sex was 32.12% (95% CI 30.27-34.00), and spousal communication was 48.87% (95% CI 46.85-50.90). Nearly one in five male (18.20%) had not used condom during extramarital sex. Interestingly, male who had more than three or equal children were less likely to have perpetrated domestic violence compared with those who had less children. Older male aged 25 and above were more likely (AORs = 1.55, 95% CI 1.19-2.03) to have extramarital sex compared with male aged 24 or below. Those male who had studied secondary or higher level of education were less likely to have extramarital sex compared to those who had primary level or no education. Male who had higher income were more likely to have spousal communication compared to those who had less income. Surprisingly, those male who had extramarital sex were less likely to have spousal communication compared with those was not involved in extramarital sex. Conclusion Practice of domestic violence and extramarital sex is quite common among married male in Nepal, where spousal communication is sparse. These findings can be used to advocate for immediate attention and activities needs to be endorsed by policymakers and programmers. PMID:24924872

    Sex workers are considered a high-risk group for sexually transmitted infections, including human immunodeficiency virus (HIV), and are often targeted by prevention interventions with safer sex messages. The purpose of this study was to explore the extent to which knowledge of HIV and perception of risk influence safer sex practices among female sex workers (FSWs) in Port Moresby, Papua New Guinea. FSWs (n = 174) were recruited from 19 sites to participate in the study. Qualitative data were collected using semistructured interviews with FSWs (n = 142) through focus group discussions and (n = 32) individual interviews. In addition, quantitative data were collected from all FSWs using a short structured, demographic questionnaire. Data were analyzed using recurring themes and calculations of confidence intervals. Despite some common misperceptions, overall, most FSWs were basically aware of the risks of HIV and informed about transmission and prevention modalities but used condoms inconsistently. Most reported using condoms ‘sometimes’, almost one-sixth ‘never’ used condoms, only a fraction used condoms ‘always’ with clients, and none used condoms ‘always’ with regular sexual partners (RSPs). Among these FSWs, being knowledgeable about the risks, transmission, and prevention of HIV did not translate into safe sex. The findings suggest that certain contextual barriers to safer sex practices exist. These barriers could heighten HIV vulnerability and possibly may be responsible for infection in FSWs. Specific interventions that focus on improving condom self-efficacy in FSWs and simultaneously target clients and RSPs with safer sex messages are recommended. PMID:21445375

    This study examines the influence of social networks on the sexual relations of migrant construction workers in Ha Noi, Viet Nam. Research included observation and interviews with members of two different groups of workers. The first group, together with their employer (cai), came from the same village; the second group came from different villages. Of interest in the present study was how social relationships among workers and their employers influence extra-marital sexual activity. In the group where workers and their cai came from the same village of origin, fear of acquiring a bad reputation made these workers reluctant to seek sex services, since accounts of their behaviour were transmitted quickly home. In contrast, workers from the group who came from different villages often went out together to purchase sex. The absence of direct links to their villages of origin made it easier for these latter workers to conceal their activity. The implication of these findings for sexual safety and risk are discussed.

    Background Stigma involves discrediting a person or group based on a perceived attribute, behaviour or reputation associated with them. Sex workers (SW) and men who have sex with men (MSM) are key populations who are often at increased risk for the acquisition and transmission of HIV and who are affected by stigma that can negatively impact their health and well-being. Although stigma was included as an indicator in the US National HIV/AIDS Strategic Plan and there have been consultations focused on adding a stigma indicator within PEPFAR and the Global Fund in relation to potentiating HIV risks among key populations, there remains limited consensus on the appropriate measurement of SW- or MSM-associated stigma. Consequently, this systematic review summarizes studies using quantitative, qualitative, or mixed methods approaches to measure stigma affecting sex workers and men who have sex with men. Methods and findings This systematic review included English, French, and Spanish peer-reviewed research of any study design measuring SW- or MSM-associated stigma. Articles were published from January 1, 2004 to March 26, 2014 in PsycINFO, PubMed, EMBASE, CINAHL Plus, Global Health, and World Health Organization Global Health Library Regional Indexes. Of the 541 articles reviewed, the majority measured stigma toward MSM (over 97%), were conducted in North America, used quantitative methods, and focused on internalized stigma. Conclusions With the inclusion of addressing stigma in several domestic and international HIV strategies, there is a need to ensure the use of validated metrics for stigma. The field to date has completed limited measurement of stigma affecting sex workers, and limited measurement of stigma affecting MSM outside of higher income settings. Moving forward requires a concerted effort integrating validated metrics of stigma into health-related surveys and programs for key populations. PMID:29190642

    Full Text Available Abstract Background Good work ability is very important in young workers, but knowledge of work situations that influence work ability in this group is poor. The aim of this study was to assess whether changes in self-reported work factors are associated with self-reported work ability among young female and male workers. Methods A sample of 1,311 (718 women and 593 men was selected from a Swedish cohort of workers aged 21–25 years. At baseline and at 1-year follow-up, participants completed a self-administrated questionnaire including ratings of physical and psychosocial work factors and current work ability. Prevalence ratios were calculated to assess univariate and multivariate associations between changes in work factors and changes in work ability. Results Decreased job control (PR 1.7, 95% CI 1.49–2.12 and increased negative influence of job demands on private life (PR 1.5, 95% CI 1.25–1.69 were associated with reduced work ability for both female and male workers in the multivariate analyses. Among female workers, an association was found between improved work ability and increased social support at work (PR 2.4, CI 1.43–3.95. For male workers, increased job control (PR 2.3, 95% CI 1.21–4.54 and decreased negative influence of job demands on private life (PR 2.1, 95% CI 1.10–3.87 were associated with improved work ability in the multivariate analyses. Conclusions Decreased job control and increased negative influence of job demands on private life over time seem to be the most important work factors associated with reduced work ability among young workers of both sexes. Increased social support at work, increased job control, and decreased negative influence of job demands on private life were also found to be the main work factors associated with improved work ability, although with possible gender differences.

    Full Text Available Abstract Background Cervical cancer is the most frequently diagnosed malignancy among women in southern Vietnam where its incidence is one of the highest observed worldwide. Results Cervical HPV DNA infection was measured in a cross-sectional sample of 282 female sex workers (FSW in Soc Trang province in southern Vietnam. HPV DNA was detected in 85% of FSW and prevalence did not vary by age. Thirty-five HPV genotypes were detected; HPV 52 was the most common type. Half of HPV-positive women were infected with oncogenic types and 37% were infected with multiple genotypes. The prevalence of oncogenic HPV infection was lower among FSW with more formal education (adj. prevalence ratio = 0.63, 95% CI 0.42–0.93, those servicing 25 or more clients per month (adj. PR = 0.66 95% CI 0.48–0.92, and those engaging in withdrawal prior to ejaculation (adj. PR = 0.68, 95% CI 0.53–0.87. Oncogenic HPV prevalence was higher among FSW with regular male partners who had other female partners (adj. PR = 1.75, 95% CI 1.34–2.28 and FSW who were HIV+ (adj. PR = 1.42, 95% CI 1.08–1.88. Conclusion Our results demonstrate that although cervical HPV infection is extremely common among FSW in southern Vietnam, prevalence varies by education level, sexual activity, habits of regular partners, and HIV status.

    Objective: To provide size estimation and to determine risky behaviours and HIV prevalence among female sex workers in Pakistan, which has progressed from a low to concentrated level of HIV epidemic. Methods: A cross-sectional study (geographic mapping and integrated behavioural and biological survey-IBBS) was conducted between August 2005 to January 2006 in Karachi, Hyderabad and Sukkur. A detailed questionnaire and dry blood spot (DBS) specimen for HIV testing were collected by trained interviewers after informed consent. The study was ethically approved by review boards in Canada and Pakistan. Results: About 14,900 female sex workers were estimated to be functional in Sindh. A total of 1158 of them were interviewed for the study. Average age of sex workers was 27.4+- 6.7 years, and the majority 787 (67.9%) were married, and uneducated 764 (65.9%). Sindhi (26.4%) was the predominant ethnicity. Mean number of paid clients was 2.1+-1.2. Three workers were confirmed HIV positive (0.75%, 95 percent CI 0.2-2.2%) from Karachi. Condom use at last sexual act was highest (68%) among brothel-based workers from Karachi, and the lowest in Sukkur where only 1.3% street-based workers reported using a condom at last sexual act. Overall use of illicit drugs through injections was negligible. Conclusion: HIV prevalence among female sex workers in Sindh, Pakistan is low but risky behaviours are present. Well organised service delivery programmes can help promoting safer practices. (author)

    The dispersal ability of F-1 male Asian corn borer, Ostrinia furnacalis (Guenee), irradiated with 100, 150 and 200 Gy Separately in parental generation were tested by marking (with Calco oil red or Sudan blue internally)-releasing-recapturing (with synthesized sex pheromone) method in the field where the farthest distance from release point to pheromone trap was 550 m. The results showed that, as compared with the normal male moths, despite of the fact that a part of the irradiated F-1 males had lost dispersal ability or taxis to sex pheromone, there was no significant difference between the captured rates of irradiated F-1 males and normal males in the trap 550 m from release point, indicated that the dispersal ability or taxis to sex pheromone of irradiated F-1 males arrived at 550 m from release point are still well matched with the normal ones

    Among sex workers (SWs) in Vancouver, Canada, this study identified social, drug use, sex work, environmental-structural, and client-related factors associated with being offered and accepting more money after clients' demand for sex without a condom. Cross-sectional study using baseline (February 2010 to October 2011) data from a longitudinal cohort of 510 SWs. A 2-part multivariable regression model was used to identify factors associated with 2 separate outcomes: (1) being offered more money for sex without a condom in the last 6 months; and (2) accepting more money, among those who had been offered more money. The sample included 490 SWs. In multivariable analysis, being offered more money for sex without a condom was more likely for SWs who used speedballs, had higher average numbers of clients per week, had difficulty accessing condoms, and had clients who visited other SWs. Accepting more money for sex without a condom was more likely for SWs self-reporting as a sexual minority and who had experienced client violence and used crystal methamphetamine less than daily (versus none) and less likely for SWs who solicited mainly indoors for clients (versus outdoor/public places). These results highlight the high demand for sex without a condom by clients of SWs. HIV prevention efforts should shift responsibility toward clients to reduce offers of more money for unsafe sex. Programs that mitigate the social and economic risk environments of SWs alongside the removal of criminal sanctions on sex work to enable condom use within safer indoor workspaces are urgently required.

    Full Text Available This paper utilizes five cycles of the General Social Survey in consecutive years from 2006 through 2010 to address the issue of differential wages amongst members of same-sex couples compared to their counterparts in different-sex couples. We find that men in gay couples have wages that are statistically indistinguishable from those of males in heterosexual relationships. By contrast, a sizeable and statistically significant earnings premium exists for lesbians in same-sex couples.

    The sex drive hypothesis predicts that stronger selection on male traits has resulted in masculinization of the genome. Here we test whether such masculinizing effects can be detected at the level of the transcriptome and methylome in the adult zebrafish brain. Although methylation is globally similar, we identified 914 specific differentially methylated CpGs (DMCs) between males and females (435 were hypermethylated and 479 were hypomethylated in males compared to females). These DMCs were prevalent in gene body, intergenic regions and CpG island shores. We also discovered 15 distinct CpG clusters with striking sex-specific DNA methylation differences. In contrast, at transcriptome level, more female-biased genes than male-biased genes were expressed, giving little support for the male sex drive hypothesis. Our study provides genome-wide methylome and transcriptome assessment and sheds light on sex-specific epigenetic patterns and in zebrafish for the first time. Copyright © 2016 Elsevier B.V.

    Although long distance truck drivers have been implicated in the spread of HIV in Africa, there is a paucity of studies of their sexual cultures. This paper reports on a study of the sexual culture of drivers, mediators and commercial sex workers (CSWs) in a roadside truck stop on the Trans-Africa highway in south west Uganda. Sixty-nine truck drivers, six middlemen and 12 CSWs were interviewed using semi-structured questionnaires. Interviewing truck drivers also entailed participating in the town's nightlife and spending much time in the bars. Truck drivers stop briefly at the truck stop for various reasons: to eat, sleep, have sex and sell goods they are carrying. Middlemen mediate the latter two activities. Middlemen buy goods from the drivers and introduce them to 'suitable' women with whom they can have casual sex. Most drivers have sex when they spend the night at the truck stop, and most make use of the services of the middlemen. The most important reasons why drivers use middlemen are that the latter speak the local languages and, in particular, know the trustworthy and 'safe' (HIV-negative) women. The CSWs use middlemen mainly because they are a guarantee that the driver will pay and they usually ensure that drivers pay well. The mediation system is becoming increasingly professionalized. Most drivers claimed to use condoms during casual sex, and this was confirmed by the CSWs. General use of condoms is encouraging, particularly given the context of a culture generally opposed to condoms. The idea that middlemen can recognize 'safe' women is worrying. However, given their key position, middlemen could form the hub of an opinion leader type intervention focused on drivers and the professional group of sex workers described here, providing condoms, advising about the importance of condom use in all casual sexual encounters, giving information about HIV and STDs, and possibly referring drivers and women to appropriate sources of HIV counselling and testing

    Although female sex workers are known to be vulnerable to HIV infection, little is known about the epidemiology of HIV infection among this high-risk population in the United States. We systematically identified and critically assessed published studies reporting HIV prevalence among female sex workers in the United States. We searched for and included original English-language articles reporting data on the prevalence of HIV as determined by testing at least 50 females who exchanged sexual practices for money or drugs. We did not apply any restrictions on date of publication. We included 14 studies from 1987 to 2013 that reported HIV prevalence for a total of 3975 adult female sex workers. Only two of the 14 studies were conducted in the last 10 years. The pooled estimate of HIV prevalence was 17.3 % (95 % CI 13.5-21.9 %); however, the prevalence of HIV across individual studies varied considerably (ranging from 0.3 to 32 %) and statistical heterogeneity was substantial (I(2) = 0.89, Q = 123; p HIV among female sex workers in the United States; however, the available evidence does suggest that HIV prevalence among this vulnerable population is high.

    2018-01-01

    Objectives. To examine indoor sex workers’ strategies in preventing workplace violence and influential socio-structural conditions. Methods. Data included qualitative interviews with 85 sex workers in British Columbia, Canada, from 2014 through 2016. For analyses, we used interpretive thematic techniques informed by World Health Organization position statements on violence. Results. Robbery, nonpayment, financial exploitation, and privacy violations were frequent types of violence perpetrated by clients, landlords, and neighbors. We identified 2 themes that depicted how sex workers prevented violence and mitigated its effects: (1) navigating physical spaces and (2) navigating client relationships. Conclusions. Sex workers’ diverse strategies to prevent violence and mitigate its effects are creative and effective in many circumstances. These are limited, however, by the absence of legal and public health regulations governing occupational health and safety and stigma associated with sex work. Public Health Implications. Occupational health and safety regulatory policies that set conditions for clients’ substance and condom use within commercial sex transactions are required. Revisions to the current legal regulations governing prostitution are critical to support optimal work environments that reduce the likelihood of violence. These revisions must recognize sex work as a form of labor versus victimization. PMID:29346001

    To examine how alcohol-related HIV risk behaviors within MSM sex workers' social networks (SN) may be associated with individual risk behaviors, respondent-driven and venue-based sampling were used to collect demographic, behavioral and SN characteristics among MSM sex workers in Santo Domingo and Boca Chica (N = 220). The majority of participants reported problem drinking (71.0%) or alcohol use at their last sexual encounter (71.4%). Self-reported problem drinking was associated with SN characteristics (at least one member who recently got drunk aOR = 7.5, no religious/spiritual adviser aOR = 3.0, non-sexual network density aOR = 0.9), while self-reported alcohol use at last sex was associated with individual (drug use at last sex aOR = 4.4) and SN characteristics (at least one member with previous HIV/STI testing aOR = 4.7). Dominican MSM sex workers reported high alcohol use, which may increase their risk for HIV. A better understanding of SN factors associated with individual risk behaviors can help guide appropriate intervention development.

    Differentiation of the bipotential gonad into testis is initiated by the Y chromosome-linked gene SRY (Sex-determining Region Y) through upregulation of its autosomal direct target gene SOX9 (Sry-related HMG box-containing gene 9). Sequence and chromosome homology studies have shown that SRY most probably evolved from SOX3, which in humans is located at Xq27.1. Mutations causing SOX3 loss-of-function do not affect the sex determination in mice or humans. However, transgenic mouse studies have shown that ectopic expression of Sox3 in the bipotential gonad results in upregulation of Sox9, resulting in testicular induction and XX male sex reversal. However, the mechanism by which these rearrangements cause sex reversal and the frequency with which they are associated with disorders of sex development remains unclear. Rearrangements of the SOX3 locus were identified recently in three cases of human XX male sex reversal. We report on a case of XX male sex reversal associated with a novel de novo duplication of the SOX3 gene. These data provide additional evidence that SOX3 gain-of-function in the XX bipotential gonad causes XX male sex reversal and further support the hypothesis that SOX3 is the evolutionary antecedent of SRY.

    Sex in mammals is genetically determined and is defined at the cellular level by sex chromosome complement (XY males and XX females). The Y chromosome-linked gene sex-determining region Y (SRY) is believed to be the master initiator of male sex determination in almost all eutherian and metatherian mammals, functioning to upregulate expression of its direct target gene Sry-related HMG box-containing gene 9 (SOX9). Data suggest that SRY evolved from SOX3, although there is no direct functional evidence to support this hypothesis. Indeed, loss-of-function mutations in SOX3 do not affect sex determination in mice or humans. To further investigate Sox3 function in vivo, we generated transgenic mice overexpressing Sox3. Here, we report that in one of these transgenic lines, Sox3 was ectopically expressed in the bipotential gonad and that this led to frequent complete XX male sex reversal. Further analysis indicated that Sox3 induced testis differentiation in this particular line of mice by upregulating expression of Sox9 via a similar mechanism to Sry. Importantly, we also identified genomic rearrangements within the SOX3 regulatory region in three patients with XX male sex reversal. Together, these data suggest that SOX3 and SRY are functionally interchangeable in sex determination and support the notion that SRY evolved from SOX3 via a regulatory mutation that led to its de novo expression in the early gonad.

    Despite rapid increases in crystal methamphetamine (CM) use worldwide and established gendered patterns of use, empirical research on CM injection initiation among sex workers is limited. Given the wide range of harms associated with CM, alongside stimulant effects including sexual dis-inhibition and prolonged awake-ness, this study aimed to longitudinally investigate socio-structural predictors of initiating CM injection among sex workers in Vancouver, Canada. Data (2010-2014) were drawn from a community-based cohort of women sex workers: AESHA (An Evaluation of Sex Workers Health Access). Participants completed bi-annual interviewer-administered questionnaires and HIV/STI testing. Kaplan Meier methods and Cox proportional hazards regression were used to model predictors of CM injection initiation among CM injection-naïve participants. Of 455 participants eligible at baseline, 14.3% (n=65) injected CM for the first time over follow-up, with an incidence density of 6.79 per 100 person-years (95% Confidence Interval [CI] 5.30-8.69). In multivariable analysis, injection heroin use (Adjusted Hazard Ratio [AHR] 6.11; 95%CI 3.24-11.52), having an intimate partner who injects drugs (AHR 2.93; 95%CI 1.57-5.46), workplace violence (AHR 2.85; 95%CI 1.74-4.67), HIV seropositivity (AHR 2.69; 95%CI 1.45-5.00), and childhood abuse (AHR 1.86; 95%CI 0.99-3.49) were independently associated with initiating CM injection. Findings underscore the gendered and social risk environment of CM injection initiation among sex workers. The strong influences of historical/workplace violence, coupled with heroin injection (known to be self-medicating for post-traumatic stress) as a primary risk pathway, emphasize the urgency of increasing access to integrated, trauma-informed addiction treatment and HIV care for marginalized women.

  2. Sex differences in adults' relative visual interest in female and male faces, toys, and play styles.

    An individual's reproductive potential appears to influence response to attractive faces of the opposite sex. Otherwise, relatively little is known about the characteristics of the adult observer that may influence his or her affective evaluation of male and female faces. An untested hypothesis (based on the proposed role of attractive faces in mate selection) is that most women would show greater interest in male faces whereas most men would show greater interest in female faces. Further, evidence from individuals with preferences for same-sex sexual partners suggests that response to attractive male and female faces may be influenced by gender-linked play preferences. To test these hypotheses, visual attention directed to sex-linked stimuli (faces, toys, play styles) was measured in 39 men and 44 women using eye tracking technology. Consistent with our predictions, men directed greater visual attention to all male-typical stimuli and visual attention to male and female faces was associated with visual attention to gender conforming or nonconforming stimuli in a manner consistent with previous research on sexual orientation. In contrast, women showed a visual preference for female-typical toys, but no visual preference for male faces or female-typical play styles. These findings indicate that sex differences in visual processing extend beyond stimuli associated with adult sexual behavior. We speculate that sex differences in visual processing are a component of the expression of gender phenotypes across the lifespan that may reflect sex differences in the motivational properties of gender-linked stimuli.

    Using a socio-ecological, structural determinants framework, this study assesses the impact of municipal licensing policies and related policing practices across the Greater Vancouver Area (Canada) on the risk of violence within indoor sex work venues. Qualitative interviews were conducted with 46 migrant/immigrant sex workers, managers and owners of licensed indoor sex work establishments and micro-brothels. Findings indicate that policing practices and licensing requirements increase sex workers' risk of violence and conflict with clients and result in heightened stress, an inability to rely on police support, lost income and the displacement of sex workers to more hidden informal work venues. Prohibitive licensing and policing practices prevent sex workers, managers and owners from adopting safer workplace measures and exacerbate health and safety risks for sex workers. This study provides critical evidence of the negative public health implications of prohibitive municipal licensing in the context of a criminalised and enforcement-based approach to sex work. Workplace safety recommendations include the decriminalisation of sex work and the elimination of disproportionately high fees for licences, criminal record restrictions, door lock restrictions, employee registration requirements and the use of police as licensing inspectors.

    Sex on premises venues (SOPVs) where men have sex with men have been implicated in the spread of sexually transmissible infections, but few studies have described men's sexual encounters in SOPVs, particularly the degree to which men from different backgrounds engage in risky sexual practices. Interviewer administered surveys were conducted with 186 Australian men who have sex with men (MSM) within 48 h of visiting an SOPV. They reported their sexual practices, the characteristics of their partners and other circumstances surrounding their sexual encounters. All analyses were based on the number of sexual encounters (n = 430). Oral sex was the most common practice, occurring in 74.9% of encounters, followed by massage, frottage or kissing (53.7%), solo or mutual masturbation (36.3%), and anal sex (32.1%). Multivariate analyses revealed age as a significant factor for having protected anal sex (P = 0.001), insertive anal sex (P = 0.004) and receptive anal sex (P practices were more frequent in encounters among younger men, while masturbation (P = 0.03) was more frequent among older men. When men's sexual partners were affected by alcohol, encounters were less likely to involve unprotected anal intercourse (P = 0.006) and more likely to involve massage, frottage or kissing (P = 0.009). Men disclosed their HIV status in only 7.7% of encounters. With the likelihood of risky sexual practices varying according to background, results from this study should be used to guide interventions aiming to promote safer sex in SOPVs.

    Street-based female sex workers (SSWs) are subjected to a relatively high risk of HIV transmission, even higher than establishment-based female sex workers in China. However, very few HIV intervention programmes have targeted this particular group to date. Based in Southwest China, this study aims to identify perceived barriers, demands and suggestions on HIV prevention from the perspectives of SSWs, clients and healthcare providers in Chongqing. Face-to-face, in-depth interviews were conducted in July 2008 with 23 participants. They were recruited by purposive, convenience sampling and included 12 SSWs, 5 male clients, 4 government healthcare providers and 2 outreach workers from a community-based non-governmental organisation. Thematic analysis was used. SSWs were largely rural-to-urban migrants with a low socioeconomic status. Most of their clients shared a similar background. Both SSWs and their clients demonstrated a low awareness of HIV infection and a lack of understanding of effective preventive strategies. Financial hardships, lack of family support, fear of police arrest and stigma in relation to sex work were identified as SSWs' major barriers for accessing healthcare services. Both SSWs and their clients indicated an urgent demand for accessing adequate HIV prevention and care programmes. On the other hand, government organisations trying to provide services to this group have also encountered obstacles, specifically their limited ability to establish mutual trust. Programmes provided by community-based non-governmental organisation, however, were perceived to be more attractive. In conclusion, there remains a substantial gap between the need of adequate HIV prevention services for SSWs and their clients and what is currently available. Strengthening inter-sectoral collaboration, providing specifically tailored health services, actively involving SSW peers and their clients, and reducing stigma in the society are keys to meet this urgent demand by SSWs

  6. Exploring the population implications of male preference when the sex probabilities at birth can be altered

    Full Text Available Objective: The paper explores the population effects of male preference stopping rules and of alternative combinations of fertility rates and male-biased birth sex ratios. Methods: The 'laboratory' is a closed, stable population with five age groups and a dynamic process represented by a compact Leslie matrix. The new element is sex-selective abortion. We consider nine stopping rules, one with no male preference, two with male preference but no abortion, and six with male preference and the availability of abortion to achieve a desired number of male births. We calculate the probability distribution over the number of births and number of male births for each rule and work out the effects at the population level if the rule is adopted by all women bearing children. We then assess the impact of alternative combinations of fertility rates and male-biased sex ratios on the population. Results: In the absence of sex-selective abortion, stopping rules generally have no effect on the male/female birth proportions in the population, although they can alter the fertility rate, age distribution, and rate of growth. When sex-selective abortion is introduced the effect on male/female proportions may be considerable, and other effects may also be quite different. The contribution of this paper is the quantification of effects that might have been predictable in general but which require model-based calculations to see how large they can be. As the paper shows, they can in fact be very large: a population in which sex-selective abortion is widely practised can look quite different from what it would otherwise be.

  7. Considering risk contexts in explaining the paradoxical HIV increase among female sex workers in Mumbai and Thane, India.

    The period 2006-2009 saw intensive scale-up of HIV prevention efforts and an increase in reported safer sex among brothel and street-based sex workers in Mumbai and Thane (Maharashtra, India). Yet during the same period, the prevalence of HIV increased in these groups. A better understanding of sex workers' risk environment is needed to explain this paradox. In this qualitative study we conducted 36 individual interviews, 9 joint interviews, and 10 focus group discussions with people associated with HIV interventions between March and May 2012. Dramatic changes in Mumbai's urban landscape dominated participants' accounts, with dwindling sex worker numbers in traditional brothel areas attributed to urban restructuring. Gentrification and anti-trafficking efforts explained an escalation in police raids. This contributed to dispersal of sex work with the sex-trade management adapting by becoming more hidden and mobile, leading to increased vulnerability. Affordable mobile phone technology enabled independent sex workers to trade in more hidden ways and there was an increased dependence on lovers for support. The risk context has become ever more challenging, with animosity against sex work amplified since the scale up of targeted interventions. Focus on condom use with sex workers inadvertently contributed to the diversification of the sex trade as clients seek out women who are less visible. Sex workers and other marginalised women who sell sex all strictly prioritise anonymity. Power structures in the sex trade continue to pose insurmountable barriers to reaching young and new sex workers. Economic vulnerability shaped women's decisions to compromise on condom use. Surveys monitoring HIV prevalence among 'visible' street and brothel-bases sex workers are increasingly un-representative of all women selling sex and self-reported condom use is no longer a valid measure of risk reduction. Targeted harm reduction programmes with sex workers fail when implemented in

  8. Japan's progressive sex: male homosexuality, national competition, and the cinema.

    This essay serves as a broad investigation of the origins of what came to be called the "gay boom" in 1990's Japanese cinema: a culmination of print media, television, and especially films which made the gay male not merely a visible (political) subject but also the site of displaced contestations of gendered (female) desire. The most visible transnational signifier of the "gay boom" was the 1992 film Okoge, a film which, in keeping with a Japanese trend which relocates the gay male as a safe displacement of female desire, posits the heterosexual female as the audience's point of identification in a film about the lives of gay Japanese men. Using this as a starting point, this essay seeks to explore how male homosexuality and gender construction operate within both Japanese nationalism and the transnational discourse of Japanese cinema's dissemination.

    Sexual partner preferences can be strengthened, weakened or even drastically modified via Pavlovian conditioning. For example, conditioned same-sex partner preference develops in sexually-naïve male rats that undergo same-sex cohabitation under the effects of quinpirole (QNP, D2 agonist). Here, we assessed the effect of prior heterosexual experience on the probability to develop a conditioned same-sex preference. Naïve or Sexually-experienced males received either Saline or QNP and cohabited during 24h with a male partner that bore almond scent on the back as conditioned stimulus. This was repeated every 4days for a total of three trials and resulted in four groups (Saline-naïve, Saline-experienced, QNP-naïve, QNP-experienced). Social and sexual preference were assessed four days after the last conditioning trial in a drug-free test in which experimental males chose between the scented familiar male and a novel sexually receptive female. Results showed that Saline-naïve, Saline-experienced and QNP-experienced displayed a clear preference for the female (opposite-sex). By contrast, only QNP-naïve males displayed a same-sex preference. Accordingly, QNP-experienced males were not affected by the conditioning process and continued to prefer females. We discuss the effects of copulation and D2 agonists on the facilitation and/or disruption of conditioned partner preferences. Copyright © 2017 Elsevier B.V. All rights reserved.

    Previous studies have classified cameramen's job as physiologically heavy work and identified the risk factors of work-related musculoskeletal disorders (WRMDs) in cameramen. However, those studies limited their research subjects to cameramen. In this study, we compared the frequency and severity of WRMDs between cameramen and office workers. A total of 293 subjects working in four broadcasting companies in Korea were recruited. A questionnaire survey was conducted for a month, starting in October 2016. The subjects were divided into cameramen and office workers according to their occupation. We compared the frequency and severity of WRMDs and ergonomic risk assessment results between the two groups. The high-risk WRMD group had a higher proportion of cameramen than office workers. Moreover, the high ergonomic risk group also had a higher proportion of cameramen than office workers for WRMDs in the upper extremities and waist+lower extremities. In the multivariable-adjusted model comparing cameramen and office workers, the odds ratio (OR) with 95% confidence interval (95% CI) for high-risk WRMDs was 3.50 (95% CI: 1.92-7.72) for the upper extremities and 3.18 (95% CI: 1.62-6.21) for the waist and the lower extremities. The ORs by body parts were 3.11 (95% CI: 1.28-7.57) for the neck, 3.90 (95% CI: 1.79-8.47) for the shoulders, and 4.23 (95% CI: 1.04-17.18) for the legs and feet. Our study suggests that cameramen are at high risk of WRMDs. Workplace improvements and management of the neck, shoulders, and lower extremities, which are susceptible to WRMDs, are necessary to prevent musculoskeletal disorders among cameramen.

    Research on the determinants of condom use and condom non-use generally has relied on self-reported data with questionable validity. We identified predictors of recent, unprotected sex among 331 female sex workers in Madagascar using two outcome measures: self-reports of unprotected sex within the past 48 h and detection of prostate-specific antigen (PSA), a biological marker of recent semen exposure. Multivariable logistic regression revealed that self-reported unprotected sex was associated with three factors: younger age, having a sipa (emotional partner) in the prior seven days, and no current use of hormonal contraception. The sole factor related to having PSA detected was prevalent chlamydial infection (adjusted odds ratio, 4.5; 95% confidence interval, 2.0-10.1). Differences in predictors identified suggest that determinants of unprotected sex, based on self-reported behaviors, might not correlate well with risk of semen exposure. Caution must be taken when interpreting self-reported sexual behavior measures or when adjusting for them in analyses evaluating interventions for the prevention of HIV/STIs.

    Prior studies with men who have sex with men have documented a strong association between substance use with sex and risk for acquisition of HIV. However, few studies have been conducted about gay male couples' use of substances with sex, despite the fact that between one third and two thirds of men who have sex with men acquire HIV from their relationship partners. The present study sought to (1) describe whether one or both partners in the male couple uses substances with sex-by substance type-within and/or outside of their relationship, and (2) assess whether differences exist in those who use substances with sex within and outside the relationship by the couples' HIV status. Dyadic data for this analysis were collected in the United States from a nation-wide cross-sectional Internet study about male couples' relationships and behaviors. Couple-level descriptive and comparative analyses were employed with 361 male couples. Except for alcohol, most couples did not use substances with sex. Of those who did, rates of who used it with sex and substance type within the relationship varied; most couples only had one partner who used substances with sex outside the relationship. Significantly higher proportions of concordantly HIV-negative and HIV-positive couples had both partners who used substances (all types) with sex within their relationship over discordant couples. Most couples had one partner who used outside the relationship; only marijuana and erectile dysfunction medication use with sex significantly differed by couples' HIV status. Findings indicate the need to conduct additional research for prevention development. © The Author(s) 2014.

    Women report a wide variety of reasons to have sex (e.g., Meston & Buss, 2010), and while it is reasonable to assume that those reasons may vary based on the context of the relationship, this assumption has not yet been tested. The purpose of this study was to explore how relationship type, sexual attraction, and the gender of one's partner interact and affect the sexual motivations of women. A total of 510 women (361 who reported exclusively other-sex attraction and 149 who reported same-sex/bisexual attraction) completed the YSEX? questionnaire. Participants rated their sexual motivations for casual sex and sex in a committed relationship with male and/or female partners, depending on reported sexual attraction. Results showed that relationship type affected reported motivation for sex: physical motivations were more strongly endorsed for casual sex, whereas emotional motivations were more strongly endorsed for sex in committed relationships. No significant differences in motivation were reported between women who reported same-sex attraction and those who did not. Women who reported bisexual attraction and identified as being lesbian, bisexual, or another sexual minority reported no significant differences in motivation for sex with male or female partners. The results of this study highlight the importance of relationship context when discussing sexual motivation and suggest a high degree of similarity in motivation for women, regardless of sexual orientation or gender of partner.

    Full Text Available This study investigated the effect of implementing the act of prohibition on sex trafficking (PST on sexually transmitted disease (STD infections among South Korean female sex workers (FSWs working at prostitution blocks. Research data were collected twice through the Korean government-sanctioned survey for female sex workers (1st wave = 1,083; 2nd wave = 926. We examined the associations among health behavior, working conditions, and the effect of PST act via hierarchical logistic regression analyses using propensity score matching. After adjusted covariates, the risk probability was 0.288 times lower among FSWs who had remained in prostitute blocks after the PST act enforcement compared to FSWs who had worked before the PST. Similarly, the risk probability for a gonorrhea infection was 0.219 times lower among FSWs who had remained in prostitute blocks after the PST act compared to FSWs who had worked before the PST. Therefore, this study showed that, besides already known factors, the implementation and establishment of the PST Act was a strong factor that suppressed STD infections among FSWs.

  18. Tribolium castaneum Transformer-2 regulates sex determination and development in both males and females.

    2013-12-01

    Tribolium castaneum Transformer (TcTra) is essential for female sex determination and maintenance through the regulation of sex-specific splicing of doublesex (dsx) pre-mRNA. In females, TcTra also regulates the sex-specific splicing of its own pre-mRNA to ensure continuous production of functional Tra protein. Transformer protein is absent in males and hence dsx pre-mRNA is spliced in a default mode. The mechanisms by which males inhibit the production of functional Tra protein are not known. Here, we report on functional characterization of transformer-2 (tra-2) gene (an ortholog of Drosophila transformer-2) in T. castaneum. RNA interference-mediated knockdown in the expression of gene coding for tra-2 in female pupae or adults resulted in the production of male-specific isoform of dsx and both female and male isoforms of tra suggesting that Tra-2 is essential for the female-specific splicing of tra and dsx pre-mRNAs. Interestingly, knockdown of tra-2 in males did not affect the splicing of dsx but resulted in the production of both female and male isoforms of tra suggesting that Tra-2 suppresses female-specific splicing of tra pre-mRNA in males. This dual regulation of sex-specific splicing of tra pre-mRNA ensures a tight regulation of sex determination and maintenance. These data suggest a critical role for Tra-2 in suppression of female sex determination cascade in males. In addition, RNAi studies showed that Tra-2 is also required for successful embryonic and larval development in both sexes. Copyright © 2013 Elsevier Ltd. All rights reserved.

    A collaborative study, supported by the Biomed2 Programme of the European Community, was initiated to optimise the aetiological diagnosis in genetic or gonadal males with intersex disorders, a total of 67 patients with external sexual ambiguity, testicular tissue and/or a XY karyotype. In patients with gonadal dysgenesis or true hermaphroditism, the incidence of vaginal development was 100%, a uterus was present in 60%; uni or bilateral cryptorchidism was seen in nearly all cases of testicular dysgenesis (99%) but in only 57% of true hermaphrodites. Mean serum levels of anti-mullerian hormone and of serum testosterone response to chorionic gonadotropin stimulation were significantly decreased in both conditions, by comparison with patients with unexplained male pseudohermaphroditism or partial androgen insensitivity (PAIS). Mutations in the androgen receptor, 90% within exons 2-8, were detected in patients with PAIS. Clinically, a vaginal pouch was present in 90%, cryptorchidism in 36%. In 52% of cases, no diagnosis could be reached, despite an exhaustive clinical and laboratory work-up, including routine sequencing of exons 2-8 of the androgen receptor. By comparison with PAIS, unexplained male pseudohermaphroditism was characterised by a lower incidence of vaginal pouch (55%) and cryptorchidism (22%) but a high incidence of prematurity/intrauterine growth retardation (30%) or mild malformations (14%). reaching an aetiological diagnosis in cases of male intersex is difficult because of the variability of individual cases. Hormonal tests may help to discriminate between partial androgen insensitivity and gonadal dysgenesis/true hermaphroditism but are of less use for differentiating from unexplained male pseudohermaphroditism. Sequencing of exons 2-8 of the androgen receptor after study of testosterone precursors following human chorionic gonadotrophin stimulation is recommended when gonadal dysgenesis and true hermaphroditism can be excluded.

    Young female sex workers (YFSWs) are confronted with significant threats during sex work. The present cross-sectional study examined different levels of threats (i.e., threats to life and health, threats to humanity, threats to control of work and financial security, and the threats to future) experienced by 87 YFSWs (age 16-25) in Hong Kong, and identified their association with mental health (i.e., psychological well-being) together with other factors, including childhood trauma, self-efficacy, hope, and social support. Results showed that the participants encountered a significant number of threats. More than half reported that they had a condom removed by clients during sex (51.7%); or have been humililated by clients (51.7%). Because of sex work, about a quarter (25.3%) have had sexually transmitted disease, and respectively 10.3% and 12.6% have had abortion and unplanned pregnancy. The majority have had friends found out that they engaged in sex work (72.4%). They also showed a high level of worry about the various threats. Multiple linear regression analysis showed that childhood trauma (β = -.26) and worry about threats during sex work (β = -.22) were significantly negative predictors, while self-efficacy (β = .20) and hope (β = .27) were significantly positive predictors of mental health. Future services should improve YFSWs' skills to minimize potential threats during female sex work, address the structural correlates and relieve their worries, and empower them with more hope and self-efficacy in choosing clients.

    Mortality is described in a cohort of 3039 men who were employed between 1940 and 1973 at a company involved in the production of thorium and rare earth chemicals from monazite sand. The standardized mortality ratio (SMR) for all causes was 1.05. SMR's were high for cancers of the lung (1,44), rectum (1.90), and pancreas (2.01), and for motor vehicle accidents (1.64). A subgroup of 592 men who worked for one year or longer in selected jobs (laborer, operator, maintenance) was followed up more intensively. SMR's were high for both lung cancer (1.62; 95% CL = 0.78 and 2.98) and pancreatic cancer (4.01; 95% CL = 1.30 and 9.34). The higher proportion of smokers in this subgroup relative to US males could have explained at least part of the excess mortality from lung cancer. Continued follow-up of the cohort in morbidity and mortality studies is needed to evaluate further these possible long-term effects of exposure to radioactivity and chemicals in the thorium extraction process

    This study examined associations between reports of receiving education on topics commonly included in sex education (e.g., abstinence only, comprehensive) prior to age 18 years and contraceptive use at the last sex among heterosexually active, 15- to 20-year-old males in the United States. Cross-sectional data from 539 males participating in the 2011-2013 National Survey of Family Growth were analyzed. Bivariate and multinomial logistic regression analyses adjusting for confounding estimated associations between receipt of seven sex education topics (e.g., information on HIV/AIDS, how to say no to sex) and contraceptive use at the last sex (i.e., dual barrier and female-controlled effective methods, female-controlled effective method only, barrier method only, and no method). Nearly, all participants (99%) reported receiving sex education on at least one topic. Education on sexually transmitted diseases (94.7%) and HIV/AIDS (92.0%) were the most commonly reported topics received; education on where to get birth control was the least common (41.6%). Instruction about birth control methods (adjusted odds ratio [AOR] = 3.01; 95% confidence interval [CI] = 1.32-6.87) and how to say no to sex (AOR = 3.39; CI = 1.33-8.64) were positively associated with dual contraception compared to no use. For each additional sex education topic respondents were exposed to, their odds of using dual methods compared to no method was 47% greater (AOR = 1.47; CI = 1.16-1.86). Exposure to a larger number of sex education topics is associated with young men's report of dual contraception use at the last sex. Comprehensive sex education, focusing on a range of topics, may be most effective at promoting safer sex among adolescent males. Copyright © 2016 Society for Adolescent Health and Medicine.

  8. Controversies of Sex Re-assignment in Genetic Males with Congenital Inadequacy of the Penis.

    Raveenthiran, Venkatachalam

    2017-09-01

    Sex assignment in 46XY genetic male children with congenital inadequacy of the penis (CIP) is controversial. Traditionally, children with penile length less than 2 cm at birth are considered unsuitable to be raised as males. They are typically re-assigned to female-sex and feminizing genitoplasty is usually done in infancy. However, the concept of cerebral androgen imprinting has caused paradigm shift in the philosophy of sex re-assignment. Masculinization of the brain, rather than length of the penis, is the modern criterion of sex re-assignment in CIP. This review summarizes the current understanding of the complex issue. In 46XY children with CIP, male-sex assignment appears appropriate in non-hormonal conditions such as idiopathic micropenis, aphallia and exstrophy. Female-sex re-assignment appears acceptable in complete androgen insensitivity (CAIS), while partial androgen insensitivity syndrome (PAIS) patients are highly dissatisfied with the assignment of either sex. Children with 5-alpha reductase deficiency are likely to have spontaneous penile lengthening at puberty. Hence, they are better raised as males. Although female assignment is common in pure gonadal dysgenesis, long-term results are not known to justify the decision.

  9. The male sex pheromone of the butterfly Bicyclus anynana: towards an evolutionary analysis.

    Caroline M Nieberding

    Full Text Available BACKGROUND: Female sex pheromones attracting mating partners over long distances are a major determinant of reproductive isolation and speciation in Lepidoptera. Males can also produce sex pheromones but their study, particularly in butterflies, has received little attention. A detailed comparison of sex pheromones in male butterflies with those of female moths would reveal patterns of conservation versus novelty in the associated behaviours, biosynthetic pathways, compounds, scent-releasing structures and receiving systems. Here we assess whether the African butterfly Bicyclus anynana, for which genetic, genomic, phylogenetic, ecological and ethological tools are available, represents a relevant model to contribute to such comparative studies. METHODOLOGY/PRINCIPAL FINDINGS: Using a multidisciplinary approach, we determined the chemical composition of the male sex pheromone (MSP in the African butterfly B. anynana, and demonstrated its behavioural activity. First, we identified three compounds forming the presumptive MSP, namely (Z-9-tetradecenol (Z9-14:OH, hexadecanal (16:Ald and 6,10,14-trimethylpentadecan-2-ol (6,10,14-trime-15-2-ol, and produced by the male secondary sexual structures, the androconia. Second, we described the male courtship sequence and found that males with artificially reduced amounts of MSP have a reduced mating success in semi-field conditions. Finally, we could restore the mating success of these males by perfuming them with the synthetic MSP. CONCLUSIONS/SIGNIFICANCE: This study provides one of the first integrative analyses of a MSP in butterflies. The toolkit it has developed will enable the investigation of the type of information about male quality that is conveyed by the MSP in intraspecific communication. Interestingly, the chemical structure of B. anynana MSP is similar to some sex pheromones of female moths making a direct comparison of pheromone biosynthesis between male butterflies and female moths relevant

    Full Text Available This study aims to characterize the profile of male injecting drug users who have sex with other men (MSM IDUs recruited through a cross-sectional multi-city survey (AjUDE-Brasil II Project in six Brazilian cities, in 2000-2001. MSM IDUs were compared to other male IDUs using bivariate and multivariate procedures (logistic regression and answer tree analysis with the CHAID algorithm. Among the 709 male IDUs, 187 (26.4% reported ever having had sex with other men, while only 37 reported sex with other men in the previous six months. MSM IDUs were more likely to be unemployed (OR = 2.3, to have injected tranquilizers (OR = 3.6, and to be HIV-seropositive (OR = 2.1, compared to other male IDUs. Male same-sex relations in this subgroup appear to be associated with strategies to finance drug consuming habits, including sex for drugs with occasional female partners or obtaining injection paraphernalia from occasional sex partners. Further studies should focus on this especially vulnerable subgroup of IDUs, due to the bidirectional and complex interrelationships between their drug injecting habits and sexual risk behaviors.

    The social context within which women engaged in sex work at a popular truck stop in South Africa are placed at risk of human immunodeficiency virus (HIV) infection and the factors that influence their ability to reduce their risk were assessed. Using qualitative and quantitative techniques, an elected sex worker from within the group collected all data. Given the various pressing needs for basic survival, the risk of HIV infection is viewed as one more burden imposed on these women by their lack of social, legal, and economic power. Violence, or the threat thereof, plays an important role in their disempowerment. In the few instances in which sex workers were able to insist on condom use, it resulted in a decrease in earnings, loss of clients, and physical abuse. Recommendations to reduce the sex workers' risk for HIV infection include negotiation and communication skills to enable them to persuade their clients to use condoms; development of strategies through which they can maximally use their group strength to facilitate unified action; and accessibility of protective methods they can use and control, such as intravaginal microbicides.

    This article narrates an inspiring discovery for development professionals who are searching for ways to empower women to protect themselves, their partners and families from HIV infection. This was based on the experience of the author as she came across a movement of sex workers who successfully negotiated safe sex in the heart of Calcutta, India. Employing focus group discussions, informal interviews and home visits during 1999, the author discovered that a Sexually Transmitted Disease/HIV Intervention Project has been set up to promote disease control and condom distribution among these sex workers. Operating on three principles for its work--respect, recognition, and reliance, the program aims to create an impact on the sex workers themselves and their peers. Likewise, the need to build alliances with clients, training the police and forming the Durbar Mahila Samanvaya Committee were deemed as necessary. Several lessons were learned during the course of the research: use of stories and history to rally the community; retaining flexibility, meeting changing needs; using drama to promote communication; and negotiating with men and opposing patriarchy.

    The Bolivian indigenous Ayoreo ethnic people are vulnerable to sexually transmitted infections and HIV. Ayoreo women who also work in sex trades belong to an extremely high-risk group, and prevention programs are not delivering effective outcomes for them. The aim of our study was to explore, describe, and understand behavioral and cultural patterns related to sexual and reproductive health in Ayoreo sex workers. A qualitative-ethnographic study was designed; data were collected through participant observation and in-depth interviews with sex workers and key informants. Two fundamental themes contributing to HIV risk for female Ayoreo sex workers in Bolivia emerged: reproductive/sexual freedom and sociocultural risk determinants. We concluded that the in-depth examination of the sexual-reproductive culture amongst the Ayoreo has provided useful information, which might contribute to the cultural adaptation and design of future policies and prevention programs for sexually transmitted infections and HIV in this group.

    OBJECTIVE: To describe the sampling techniques and survey procedures used in identifying male clients who frequent brothels to buy sexual services from female sex workers in Dakar, Senegal, with the aim of measuring the prevalence of human immunodeficiency virus (HIV) infection and investigating related risk behaviours. METHODS: Surveys were conducted in seven brothels in Dakar, Senegal. Clients were identified "by surprise" and interviewed and requested to donate saliva for HIV testing. RESULTS: Of the 1450 clients of prostitutes who were solicited to enter the study, 1140 (79.8%) agreed to be interviewed; 1083 (95%) of these clients provided saliva samples for testing. Of the samples tested, 47 were positive for HIV-1 or HIV-2, giving an HIV prevalence of 4.4%. CONCLUSION: The procedures adopted were successful in reaching the target population. Men present in the brothels could not deny being there, and it proved possible to explain the purpose of the study and to gain their confidence. Collection of saliva samples was shown to be an excellent method for performing HIV testing in difficult field conditions where it is hard to gain access to the population under study. The surveying of prostitution sites is recommended as a means of identifying core groups for HIV infection with a view to targeting education programmes more effectively. In countries such as Senegal, where the prevalence of HIV infection is still low, interventions among commercial sex workers and their clients may substantially delay the onset of a larger epidemic in the general population.

    Full Text Available Introduction. Female sex workers (FSWs are a group at increased risk for human immunodeficiency virus (HIV infection, and inconsistent condom use with clients is a known risk factor for infection in this group. Objective. The aim of the study was to determine factors associated with inconsistent condom use with clients among female sex workers in Podgorica, Montenegro. Methods. We conducted an HIV bio-behavioral cross-sectional study in a sample of female sex workers recruited by snowball sampling. Results. A total of 142 FSWs were recruited. Eighty-one (57.0% of them used condoms consistently with clients. HIV prevalence was 0.0%. In the multivariate analysis inconsistent condom use with clients in the previous month was associated with clients’ negative personal attitude [age-adjusted odds ratio (AOR = 22.7, 95% confidence interval (CI = 2.3-228.0] or client’s indifference (AOR = 13.0, 95% CI = 1.4-118.9 towards using condom during sex with sexual workers, decision making by clients or by mutual agreement with client about using a condom (AOR = 10.2, 95% CI = 3.7-28.0, and early age of first sex (AOR = 5.4, 95% CI = 1.6-18.5. Conclusion. Our results suggest not only the need for further promotion of condom use, information and education for FSW but also the need to strengthen negotiation skills of FSWs with clients on regular use of condoms, as well as the need to extend prevention programs to clients of FSWs.

    Structural interventions focused on community mobilisation to engender an enabling social context have reduced sexual risk behaviours among sex workers. Interventions to date have increased social participation and shown an association between participation and safer sex. Social participation could modify risk for other health behaviours, particularly drug use. We assessed social participation and drug use before and after implementation of a clinical, social and structural intervention with sex workers intended to prevent sexually transmitted infections/HIV infection. We followed 420 sex workers participating in the Encontros intervention in Corumbá, Brazil, between 2003 and 2005. We estimated the association of participation in external social groups with drug use at baseline and follow-up using logistic regression and marginal modelling. Follow-up analyses of preintervention/postintervention change in drug use employed inverse probability weighting to account for censoring and were stratified by exposure to the intervention. Social participation showed a protective association with drug use at baseline (1 SD higher level of social participation associated with 3.8% lower prevalence of drug use, 95% CI -0.1 to 8.3). Among individuals exposed to Encontros, higher social participation was associated with an 8.6% lower level of drug use (95% CI 0.1 to 23.3). No significant association was found among the unexposed. A structural intervention that modified sex workers' social environment, specifically participation in external social groups, was associated with reduced drug use. These findings suggest that sexual risk prevention initiatives that enhance social integration among marginalised populations can produce broad health impacts, including reductions in drug use.

    In budgerigars (Melopsittacus undulatus), a social parrot in which females are socially dominant, males of all ages engage in a set of behaviors with other males that closely resembles the repertoire used in heterosexual courtship. One adaptive hypothesis for this tendency, the "courtship practice hypothesis," posits that males with greater experience in same-sex activities develop superior skills that increase their courtship success with females. To test this hypothesis, we measured individ...

    Mental disorders are increasing and their influence on productivity is a concern in the workplace. However, few studies have investigated depression among blue-collar and white-collar workers in the manufacturing industry. The purpose of this study was to clarify the factors associated with depressive symptoms, focusing on lifestyles and insomnia. A self-administered questionnaire survey was conducted of 1,963 workers at an annual health checkup in a manufacturing company. Of the 1,712 respondents (response rate: 87%), 1,258 male worker subjects (blue-collar 674; white-collar 584) were analyzed after excluding those with mental diseases. The questionnaire included items on basic attributes and lifestyle. The Athens Insomnia Scale (AIS) and The Center for Epidemiologic Studies for Depression Scale (CES-D) were used to evaluate insomnia and depressive symptoms. The incidence of depressive symptoms with CES-D scores of ≥16 was 15.1% in both the blue-collar and the white-collar workers. Insomnia with AIS scores of ≥6 were encountered in 18.8% of the blue-collar workers and 18.3% of the white-collar workers. Multiple logistic regression analyses showed that for the blue-collar workers, depressive symptoms were associated with "AIS scores ≥6" (Odds ratio (OR): 10.93; 95% confidence interval (CI): 6.12-19.15), "not get rid of fatigue with sleep" (OR: 3.36; 95%CI: 1.85-6.09), "skip breakfast over 3 times a week" (OR: 3.10; 95%CI:1.42-6.76), "no family living together" (OR: 2.08; 95%CI: 1.05-4.12), and "commuting time" (OR: 1.01; 95%CI: 1.00-1.02). For the white-collar workers, depressive symptoms were related to "AIS scores ≥6" (OR: 14.91; 95%CI: 7.54-29.49), and "no family living together" (OR: 2.54; 95%CI: 1.27-5.09). Sleep time was not associated with depression in both blue- and white-collar workers. Depressive symptoms were found in 51.6% of the blue-collar workers with insomnia with AIS scores ≥6 and 53.8% of white-collar workers. Depressive symptoms were

    Peer-led outreach is a critical element of HIV and STI-reduction interventions aimed at sex workers. We study the association between peer-led outreach to sex workers and the time to utilize health facilities for timely STI syndromic-detection and treatment. Using data on the timing of peer-outreach interventions and clinic visits, we utilize an Extended Cox model to assess whether peer educator outreach intensity is associated with accelerated clinic utilization among sex workers. Our data comes from 2705 female sex workers registered into Pragati, a women-in-sex-work outreach program, and followed from 2008 through 2012. We analyze this data using an Extended Cox model with the density of peer educator visits in a 30-day rolling window as the key predictor, while controlling for the sex workers' age, client volume, location of sex work, and education level. The principal outcome of interest is the timing of the first voluntary clinic utilization. More frequent peer visit is associated with earlier first clinic visit (HR: 1.83, 95% CI, 1.75-1.91, p educator outreach. Peer outreach density is associated with increased likelihood of-and shortened duration to-clinic utilization among female sex workers, suggesting potential staff resourcing implications. Given the observational nature of our study, however, these findings should be interpreted as an association rather than as a causal relationship.

    Sex workers have endured a high burden of HIV infection in and across HIV epidemics. A comprehensive, community empowerment-based HIV prevention intervention emphasizes sex worker organization and mobilization to address HIV risk and often includes community-led peer education, condom distribution, and other activities. Meta-analysis of such interventions suggests a potential 51% reduction in inconsistent condom use. Mathematical modeling exercises provide theoretical insight into potential impacts of the intervention on HIV incidence and burden in settings where interventions have not yet been implemented. We used a deterministic model, Goals, to project the impact on HIV infections when the community empowerment interventions were scaled up among female sex workers in Kenya, Thailand, Brazil, and Ukraine. Modeling scenarios included expansion of the comprehensive community empowerment-based HIV prevention intervention from baseline coverage over a 5-year period (5-65% in Kenya and Ukraine; 10-70% in Thailand and Brazil), while other interventions were held at baseline levels. A second exercise increased the intervention coverage simultaneously with equitable access to ART for sex workers. Impacts on HIV outcomes among sex workers and adults are observed from 2012-2016 and, compared to status quo when all interventions are held constant. Optimistic but feasible coverage (65%-70%) of the intervention demonstrated a range of impacts on HIV: 220 infections averted over 5 yrs. among sex workers in Thailand, 1,830 in Brazil, 2,220 in Ukraine, and 10,800 infections in Kenya. Impacts of the intervention for female sex workers extend to the adult population, cumulatively averting 730 infections in Thailand to 20,700 adult infections in Kenya. Impacts vary by country, influenced by HIV prevalence in risk groups, risk behaviors, intervention use, and population size. A community empowerment approach to HIV prevention and access to universal ART for female sex workers is a

    Full Text Available OBJECTIVE: To evaluate novel eligibility criteria and outreach methods to identify and recruit women at high risk of HIV-1 infection in the Caribbean. METHODS: A prospective cohort study was conducted in 2009-2012 among 799 female commercial sex workers in the Dominican Republic, Haiti, and Puerto Rico. Minimum eligibility criteria included exchange of sex for goods, services, or money in the previous 6 months and unprotected vaginal or anal sex with a man during the same period. Sites used local epidemiology to develop more stringent eligibility criteria and recruitment strategies. Participants were asked questions about HIV/AIDS and their level of concern about participating in an HIV vaccine trial. Logistic regression modeling was used to assess predictors of prevalent HIV infection and willingness to participate in a future HIV vaccine study. RESULTS: HIV prevalence at screening was 4.6%. Crack cocaine use [odds ratio (OR = 4.2, 95% confidence interval (CI (1.8-9.0] was associated with and having sex with clients in a hotel or motel [OR = 0.5, CI (0.3-1.0] was inversely associated with HIV infection. A total of 88.9% of enrolled women were definitely or probably willing to participate in a future HIV vaccine trial. CONCLUSIONS: This study indicated that local eligibility criteria and recruitment methods can be developed to identify and recruit commercial sex workers with higher HIV prevalence than the general population who express willingness to join an HIV vaccine trial.

    Because of the nature of their work, female sex workers are at risk of sexually transmitted diseases. Cross-border areas are places where this situation becomes worse. In Ethiopia, there has been a serious scarcity of studies on the time at which unsafe sexual practice starts and on factors which determine the practice among female sex workers there. Therefore, this study aimed to fill this identified gap. A total of 467 women who had been sex workers at least for three months prior to the resumption of the study were included. A structured and pre-tested questionnaire was used to collect data from July-August, 2010. Descriptive statistics was used to explore the data, and the Extended Cox-Regression model was employed to identify the predictors of time-to-unsafe sexual practice. The study participants were followed for 6, 643 person-months. The overall incidence density of unsafe sexual practice was 44.71 persons per 1000 persons-months. The hazard of unsafe sexual practice increased by 3.0 % every month (p-value =0.040) due to problem-drinking. Those female sex workers with familiarized clients had a two-fold hazard of practicing unsafe sex compared to their counterparts (AHR = 1.94 95 % CI 1.49, 2.53). The predominant sexual client type and the work place of sex workers were the other significant predictors of unsafe sexual practice. The incidence of unsafe sexual practice was found to be high among sex workers in the cross-border area. Time-to-unsafe sexual practice was significantly associated with female sex workers' status of familiarity with their clients, predominant sexual client type, their work place, and the interaction term of time and problem-drinking. Interventions need to be made on these controllable social and behavioral characteristics to help sex workers extend the duration of their safe sexual practice beyond the time they will quit sex work.

    Sexual preferences can be strongly modified by Pavlovian learning. For instance, olfactory conditioned same-sex partner preference can occur when a sexually naïve male cohabits with an scented male during repeated periods under the effects of enhanced D2-type activity. Preference is observed days later via social and sexual behaviors. Herein we explored brain activity related to learned same-sex preference (Fos-Immunoreactivity, IR) following exposure to a conditioned odor paired with same-sex preference. During conditioning trials males received either saline or the D2-type receptor agonist quinpirole (QNP) and cohabitated during 24 h with a stimulus male that bore almond scent on the back as conditioned stimulus. This was repeated every 4 days, for a total of three trials. In a drug-free final test we assessed socio/sexual partner preference between the scented male and a receptive female. The results indicated that QNP-conditioned males developed a same-sex preference observed via contact, time spent, olfactory investigations, and non-contact erections. By contrast, saline-conditioned and intact (non-exposed to conditioning) males expressed an unconditioned preference for the female. Four days later the males were exposed to almond scent and their brains were processed for Fos-IR. Results indicated that the QNP-conditioned group expressed more Fos-IR in the nucleus accumbens (AcbSh), medial preoptic area (MPA), piriform cortex (Pir) and ventromedial nucleus of the hypothalamus (VMH) as compared to saline-conditioned. Intact males expressed the lowest Fos-IR in AcbSh and VMH, but the highest in MPA and Pir. We discuss the role of these areas in the learning process of same-sex partner preferences and olfactory discrimination. Copyright © 2018 Elsevier Inc. All rights reserved.

    1983-12-01

    The historical view of masculinity/femininity posited essentially bipolar opposites, with the presence of one set of characteristics precluding the other. More recent studies of sex-role stereotypes have defined sexual orientation within clusters of socially desirable attributes which males and females perceive as differentiating males from females. This view negates the contention that psychological sex roles are composed of bipolar opposites, and concludes that the constructs of masculinity and femininity are independent dimensions rather than a single bipolar dimension. Little is known about the sex-role functioning of adolescents, yet it is during adolescence that qualitative shifts occur in interpersonal relationships and concurrent changes occur in cognitive functioning, with adolescents shifting toward hypothetical thinking and abstract ideal notions. In view of these changes, much can be learned about adult functioning by studying the sex-role perceptions of adolescents related to familial and social variables. This study examines the sex-role perceptions that adolescents hold of fathers, mothers, ideal males, ideal females, and selves. Differences exist between male and female adolescents, and significant linkages exist between sex-role identification and academic achievement.

    Women involved in both street-level and off-street sex work face disproportionate health and social inequities compared to the general population. While much research has focused on HIV and sexually transmitted infections (STIs) among sex workers, there remains a gap in evidence regarding the broader health issues faced by this population, including mental health. Given limited evidence describing the mental health of women in sex work, our objective was to evaluate the burden and correlates of mental health diagnoses among this population in Vancouver, Canada. An Evaluation of Sex Workers Health Access (AESHA) is a prospective, community-based cohort of on- and off-street women in sex work in Vancouver, Canada. Participants complete interviewer-administered questionnaires semi-annually. We analyzed the lifetime burden and correlates of self-reported mental health diagnoses using bivariate and multivariable logistic regression. Among 692 sex workers enrolled between January 2010 and February 2013, 338 (48.8%) reported ever being diagnosed with a mental health issue, with the most common diagnoses being depression (35.1%) and anxiety (19.9%). In multivariable analysis, women with mental health diagnoses were more likely to identify as a sexual/gender minority (LGBTQ) [AOR=2.56, 95% CI: 1.72-3.81], to use non-injection drugs [AOR=1.85, 95% CI: 1.12-3.08], to have experienced childhood physical/sexual trauma [AOR=2.90, 95% CI: 1.89-4.45], and work in informal indoor [AOR=1.94, 95% CI: 1.12 - 3.40] or street/public spaces [AOR=1.76, 95% CI: 1.03-2.99]. This analysis highlights the disproportionate mental health burden experienced by women in sex work, particularly among those identifying as a sexual/gender minority, those who use drugs, and those who work in informal indoor venues and street/public spaces. Evidence-informed interventions tailored to sex workers that address intersections between trauma and mental health should be further explored, alongside policies to

The objective of this study was to identify and describe maternal deaths of female sex workers in Cambodia and causes of death among their children. Methods A convenience sample of female sex workers were recruited by local NGOs that provide support to sex workers. We modified the maternal mortality section of the 2010 Cambodia Demographic and Health Survey and collected reports of all deaths of female sex workers. For each death we ask the ‘sisterhood’ methodology questions to identify maternal deaths. For child deaths we asked each mother who reported the death of a child about the cause of death. We also asked all participants about the cause of deaths of children of other female sex workers. Results We interviewed 271 female sex workers in the four largest Cambodian cities between May and September 2013. Participants reported 32 deaths of other female sex workers that met criteria for maternal death. The most common reported causes of maternal deaths were abortion (n = 13;40% and HIV (n = 5;16%. Participants report deaths of 8 of their children and 50 deaths of children of other female sex workers. HIV was the reported cause of death for 13 (36% children under age five. Conclusion This is the first report of maternal deaths of sex workers in Cambodia or any other country. This modification of the sisterhood methodology has not been validated and did not allow us to calculate maternal mortality rates so the results are not generalizable, however these deaths may represent unrecognized maternal deaths in Cambodia. The results also indicate that children of sex workers in Cambodia are at risk of HIV and may not be accessing treatment. These issues require additional studies but in the meantime we must assure that sex workers in Cambodia and their

    Full Text Available Abstract Background Heterosexual contact is the most common mode of HIV transmission in India that is largely linked to sex work. We assessed the non-use of condoms in sex work and with regular sex partners by female sex workers (FSWs, and identified its associations that could assist in planning HIV prevention programmes. Methods Detailed documentation of various aspects of sex work, and sexual behaviour with regular sex partners, was done through confidential interviews for 6648 FSWs in 13 districts in the Indian state of Andhra Pradesh. Multivariate analysis was done to understand condom non-use with clients. Results 5010 (75.4%, 1499 (22.5%, and 139 (2.1% FSWs were street-, home-, and brothel-based, respectively. Of the total 6648 FSWs, 6165 (92.7% had penetrative vaginal/anal sex with at least one client in the last 15 days, and of these 2907 (47.2%; 95% CI 41.2–53.2% reported non-use of condom with at least one of her last three clients. Lack of knowledge that HIV could be prevented (odds ratio 5.01; 95% CI 4.38–5.73, no access to free condoms (odds ratio 3.45; 95% CI 2.99–3.98, being street-based as compared with brothel-based (odds ratio 3.36; 95% CI 1.87–6.04, and no participation in FSW support groups (odds ratio 2.02; 95% CI 1.50–2.70 were the most significant predictors of condom non-use with clients. Other associations included lower social support, lower income, age >24 years, illiteracy, and living in medium-size urban or rural areas. Of the 2582 who had penetrative sex with regular sex partner within the last 7 days, 2428 (94%; 95% CI 92.1–95.9% had not used condom at last sex, and 1032 (41.8% had neither used condom consistently with clients nor with regular sex partner. Conclusion About half the FSWs do not use condom consistently with their clients in this Indian state putting them at high risk of HIV infection. Non-brothel-based FSWs, who form the majority of sex workers in India, were at a significantly higher

    Complex combinations of law, policy, and enforcement practices determine sex workers vulnerability to HIV and rights abuses. We identify "lack of recognition as a person before the law" as an important but undocumented barrier to accessing services and conclude that multi-faceted, setting-specific reform is needed-rather than a singular focus on decriminalization-if the health and human rights of sex workers are to be realized.

    The aim of this work was to study the vaginal microenvironment in sex workers from Comodoro Rivadavia, Chubut. For that purpose, BAVACO procedures were applied. A total of 229 female sex workers attended public health centers. Vaginal secretions were analyzed by Gram and Giemsa stains. The following results were obtained: normal microbiota 35.37 %, intermediate microbiota 15.72 %, bacterial vaginosis 23.14 %, microbial non-specific vaginitis, Donders'"aerobic vaginitis" 10.48 %, yeast vulvovaginitis 8.30 %, and trichomoniasis 6.99 %. The intermediate microbiota was characterized by a decrease in the number of lactobacilli and the presence of diphtheroid bacilli cell types. The population studied shared increased values of vaginal dysfunctions. These results are considered risk factors for obstetric and gynecologic diseases.

    HIV testing uptake continues to be low among Female Sex Workers (FSWs). We synthesizes evidence on barriers and facilitators to HIV testing among FSW as well as frequencies of testing, willingness to test, and return rates to collect results. We systematically searched the MEDLINE/PubMed, EMBASE, SCOPUS databases for articles published in English between January 2000 and November 2017. Out of 5036 references screened, we retained 36 papers. The two barriers to HIV testing most commonly reported were financial and time costs-including low income, transportation costs, time constraints, and formal/informal payments-as well as the stigma and discrimination ascribed to HIV positive people and sex workers. Social support facilitated testing with consistently higher uptake amongst married FSWs and women who were encouraged to test by peers and managers. The consistent finding that social support facilitated HIV testing calls for its inclusion into current HIV testing strategies addressed at FSW.

    Full Text Available Sex-specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species. Extensive ecological, behavioural and genetic studies of Heliconius butterflies have made a substantial contribution to our understanding of speciation. Male pheromones, although long suspected to play an important role, have received relatively little attention in this genus. Here, we combine morphological, chemical and behavioural analyses of male pheromones in the Neotropical butterfly Heliconius melpomene. First, we identify putative androconia that are specialized brush-like scales that lie within the shiny grey region of the male hindwing. We then describe putative male sex pheromone compounds, which are largely confined to the androconial region of the hindwing of mature males, but are absent in immature males and females. Finally, behavioural choice experiments reveal that females of H. melpomene, H. erato and H. timareta strongly discriminate against conspecific males which have their androconial region experimentally blocked. As well as demonstrating the importance of chemical signalling for female mate choice in Heliconius butterflies, the results describe structures involved in release of the pheromone and a list of potential male sex pheromone compounds.

    HIV is hyperendemic in Swaziland with a prevalence of over 25% among those between the ages of 15 and 49 years old. The HIV response in Swaziland has traditionally focused on decreasing HIV acquisition and transmission risks in the general population through interventions such as male circumcision, increasing treatment uptake and adherence, and risk-reduction counseling. There is emerging data from Southern Africa that key populations such as female sex workers (FSW) carry a disproportionate burden of HIV even in generalized epidemics such as Swaziland. The burden of HIV and prevention needs among FSW remains unstudied in Swaziland. A respondent-driven-sampling survey was completed between August-October, 2011 of 328 FSW in Swaziland. Each participant completed a structured survey instrument and biological HIV and syphilis testing according to Swazi Guidelines. Unadjusted HIV prevalence was 70.3% (n = 223/317) among a sample of women predominantly from Swaziland (95.2%, n = 300/316) with a mean age of 21(median 25) which was significantly higher than the general population of women. Approximately one-half of the FSW(53.4%, n = 167/313) had received HIV prevention information related to sex work in the previous year, and about one-in-ten had been part of a previous research project(n = 38/313). Rape was common with nearly 40% (n = 123/314) reporting at least one rape; 17.4% (n = 23/314)reported being raped 6 or more times. Reporting blackmail (34.8%, n = 113/314) and torture(53.2%, n = 173/314) was prevalent. While Swaziland has a highly generalized HIV epidemic, reconceptualizing the needs of key populations such as FSW suggests that these women represent a distinct population with specific vulnerabilities and a high burden of HIV compared to other women. These women are understudied and underserved resulting in a limited characterization of their HIV prevention, treatment, and care needs and only sparse specific and competent

    Full Text Available For the most part solutions to farm animal welfare issues, such as piglet mortality, are likely to lie within the scientific disciplines of environmental design and genetic selection, however understanding the ecological basis of some of the complex dynamics observed between parent and offspring could make a valuable contribution. One interesting, and often discussed, aspect of mortality is the propensity for it to be sex-biased. This study investigated whether known physiological and behavioural indicators of piglet survival differed between the sexes and whether life history strategies (often reported in wild or feral populations relating to parental investment were being displayed in a domestic population of pigs. Sex ratio (proportion of males (males/males+females at birth was 0.54 and sex allocation (maternal investment measured as piglet birth weight/litter weight was statistically significantly male-biased at 0.55 (t(35 = 2.51 P = 0.017, suggesting that sows invested more in sons than daughters during gestation. Despite this investment in birth weight, a known survival indicator, total pre-weaning male mortality was statistically significantly higher than female mortality (12% vs. 7% respectively z = 2.06 P = 0.040. Males tended to suffer from crushing by the sow more than females and statistically significantly more males died from disease-related causes. Although males were born on average heavier, with higher body mass index and ponderal index, these differences were not sustained. In addition male piglets showed impaired thermoregulation compared to females. These results suggest male-biased mortality exists despite greater initial maternal investment, and therefore reflects the greater susceptibility of this sex to causal mortality factors. Life history strategies are being displayed by a domestic population of pigs with sows in this study displaying a form of parental optimism by allocating greater resources at birth

    Full Text Available Abstract Background Condoms are effective in preventing the transmission of HIV and other sexually transmitted infections, when properly used. However, recent data from surveys of female sex workers (FSWs in Karnataka in south India, suggest that condom breakage rates may be quite high. It is important therefore to quantify condom breakage rates, and examine what factors might precipitate condom breakage, so that programmers can identify those at risk, and develop appropriate interventions. Methods We explored determinants of reported condom breakage in the previous month among 1,928 female sex workers in four districts of Karnataka using data from cross-sectional surveys undertaken from July 2008 to February 2009. Using stepwise multivariate logistic regression, we examined the possible determinants of condom breakage, controlling for several independent variables including the district and client load. Results Overall, 11.4% of FSWs reported at least one condom break in the previous month. FSWs were much more likely to report breakage if under 20 years of age (AOR 3.43, p = 0.005; if divorced/ separated/widowed (AOR 1.52, p = 0.012; if they were regular alcohol users (AOR 1.63, p = 0.005; if they mostly entertained clients in lodges/rented rooms (AOR 2.99, p = 0.029 or brothels (AOR 4.77, p = 0.003, compared to street based sex workers; if they had ever had anal sex (AOR 2.03, p = 0.006; if the sex worker herself (as opposed to the client applied the condom at last use (AOR 1.90, p Conclusions The reported incidence of condom breakage was high in this study, and this is a major concern for HIV/STI prevention programs, for which condom use is a key prevention tool.

    Commercial sex worker is one of the groups with the highest level of susceptibility against HIV infection. They are 13,5 fold more prone to a living with HIV infection than the female of non commercial sex workers. Moreover, these commercial sex workers are also stigmatized with social sanction and discrimination against people with HIV-AIDS. The society mostly avoid them, deject them, isolate them, insult them, despise them, distrust them, and even go against the existence of those suffering from or infected by HIV-AIDS. Thus, stigmatizing and discrimination are basicly highly prohibited since they can incur higher social problems. It is also vital to handle the spread of HIV-AIDS in the society as soon as possible in the attempt of fighting against the spread of the disease. Hence, being broad minded, tolerant, and caring towards them as well as working hand in hand with the community are expected to diminish, minimize, and even eradicate the outbreak of HIV-AIDS. Caring towards those suffering from the infection without stigmatizing them and discriminating them will be one of the first measurements to take to improve what is needed to prevent the prevalence and spread of the disease. Thus, the primary objective of this research is to know the perception of female commercial sex workers on the susceptibility of HIV-AIDS in Yogyakarta. The research participants were selected from three localizations in Yogyakarta namely Pasar Kembang, Bongsuwung, and Giwangan. It is revealed that the participants had a good perception on the susceptibility of AIDS infection as seen from the fact there are free avalaible condoms for them to use everytime they have a sexual intercourse with the clients. All participants were aware of their high susceptibility against the infection of STIs/HIV/AIDS and thus they want to save their skin from those diseases. Also they had a good knowledge that having an intercourse without condom may get them infected.

    Full Text Available The androgenic gland (AG, playing an important role in sex differentiation of male crustacean, is a target candidate to understand the mechanism of male development and to mine male-specific sex markers. An SSH library (designated as male reproduction-related tissues—SSH library, MRT-SSH library for short was constructed using cDNA from tissues located at the basal part of the 5th pereiopods, including AG and part of spermatophore sac, as tester, and the cDNA from the basal part of the 4th pereiopods of these male shrimp as driver. 402 ESTs from the SSH library were sequenced and assembled into 48 contigs and 104 singlets. Twelve contigs and 14 singlets were identified as known genes. The proteins encoded by the identified genes were categorized, according to their proposed functions, into neuropeptide hormone and hormone transporter, RNA posttranscriptional regulation, translation, cell growth and death, metabolism, genetic information processing, signal transduction/transport, or immunity-related proteins. Eleven highly expressed contigs in the SSH library were selected for validation of the MRT-SSH library and screening sex markers of shrimp. One contig, specifically expressed in male shrimp, had a potential to be developed as a transcriptomic sex marker in shrimp.

    To examine whether nonbarrier modern contraceptive use is associated with less consistent condom use among Kenyan female sex workers (FSWs). Researchers recruited 579 FSWs using respondent-driven sampling. We conducted multivariate logistic regression to examine the association between consistent condom use and female-controlled nonbarrier modern contraceptive use. A total of 98.8% reported using male condoms in the past month, and 64.6% reported using female-controlled nonbarrier modern contraception. In multivariate analysis, female-controlled nonbarrier modern contraceptive use was not associated with decreased condom use with clients or nonpaying partners. Consistency of condom use is not compromised when FSWs use available female-controlled nonbarrier modern contraception. FSWs should be encouraged to use condoms consistently, whether or not other methods are used simultaneously. Copyright © 2016 Elsevier Inc. All rights reserved.

    HIV partner notification involves contacting sexual partners of people who test HIV positive and referring them to HIV testing, treatment, and prevention services. To understand values and preferences of key and general populations in Rakai, Uganda, we conducted 6 focus group discussions and 63 in-depth interviews in high prevalence fishing communities and low prevalence mainland communities. Participants included fishermen and sex workers in fishing communities, male and female mainland community members, and healthcare providers. Questions explored three approaches: passive referral, provider referral, and contract referral. Qualitative data were coded and analyzed using a team-based matrix approach. Participants agreed that passive referral was most suitable for primary partners. Provider referral was acceptable in fishing communities for notifying multiple, casual partners. Healthcare providers voiced concerns about limited time, resources, and training for provider-assisted approaches. Options for partner notification may help people overcome barriers to HIV serostatus disclosure and help reach key populations.

    Though many studies have conclusively linked felt stigma and HIV, few have focused on the experiences of rejection felt by members of such socially marginalized groups as intravenous drug users (IDU) and sex workers (SW). Using focus groups, our study explored these experiences in 34 individuals (17 male UDUs and 17 female SWs) at risk of becoming infected with HIV, the objective being to discover why they engaged in maladaptive behaviors as a way of coping with felt stigma. We used deductive and inductive analysis to codify the resulting data. Concepts associated with the word stigma, emotional reactions to felt stigma, and the impact of felt stigma on self-schema helped elucidate how the internalization of felt stigma can lead to negative affective states and self-destructive behaviors (e.g., drug use and syringe exchange). Results underline the importance of developing intervention models that reduce stigma as a means of HIV prevention in vulnerable populations.

The aim of the present study was to see if previously indicated trends are being maintained after standardizing mortality rates by county for the period 1973-75. Although...... regional variations are seen, standardization by county produces only slight differences in age and cause-specific standardized mortality ratios. Earlier members of the Semiskilled Workers' Union, especially in younger age groups, are confirmed. Low mortality in older age groups, which show a deficit...... of deaths from circulatory diseases and other chronic illnesses, suggests the possibility of a survival population effect....

    The literature on positive psychology and resilience demonstrates that individuals utilize their personal strengths and environmental resources to facilitate positive adaptation. Using a qualitative approach, we investigated how these frameworks operated as self-protective strategies for female sex workers to maintain their psychological and physical well-being under stressful socioeconomic and work-related conditions. Twenty-three female sex workers in Hong Kong participated in in-depth interviews. We used the grounded theory approach for data analysis. The informants reported negative feelings in response to financial burden, clients' demands, threats to physical health, and stigma. Some female sex workers showed their resilience by being able to rationalize their role, believe their ability to make a change in life, and stay optimistic. They adopted strategies including emotional regulation and acceptance of their responsibility and limits to cope with stressful life events. The results help us understand the role of positive psychology and resilience in this vulnerable population. © The Author(s) 2014.

    To overview the status of social support on older female sex workers (OFSWs) in Qingdao and to better understand the characteristics of this egocentric social support networks. Ucinet 6 software was used to analyze the characteristics of egocentric social networks which involving 400 OFSWs who were recruited by respondent-driven sampling (RDS) method in Qingdao during March 2014 to June. Structural equation model (SEM) was used for data analysis, fitted test and estimation. A total of 400 OFSWs of Qingdao nominated 1 617 social supportive members, and the average size of egocentric social networks of OFSWs was (4.0 ± 1.5). Among all the alter egos (social support network members of the egos), 613 were female sex workers fellows, accounted for the most important part of all the social ties (37.91%). Characteristics of small size and non-relative relationships were seen more obviously among OFSWs with non-local registration and the ratings of emotional support (4.42±2.38) was significantly lower than the tangible support (5.73 ± 1.69) (Psocial support from friends who were also female sex workers. Stronger the joint strength between egos and alters, greater the homogeneity between the two was seen. Tighter relations among the alter egos, higher degree of average social support of the egos were acquired.

  15. Peer outreach work as economic activity: implications for HIV prevention interventions among female sex workers.

    Full Text Available Female sex workers (FSWs who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers' economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers' relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

    Full Text Available Background: Cardiovascular disease (CVD is mainly attributable to a combination of risk factors (RFs: tobacco use, alcohol use, high blood pressure, diabetes, unhealthy diet, and obesity which are amenable to interventions. Building construction workers are poor and vulnerable. They are also the victims of adverse working environmental conditions and subjected to health hazards of occupational origin. Objective: The aim was to study the RFs and associated sociodemographics for CVD among construction site workers. Materials and Methods: This cross-sectional study was conducted among construction site workers. A total of 172 male workers over the age of 18 years were included in the study. Modified World Health Organization Step-wise approach to chronic disease RF surveillance was used to collect data. The data were analyzed in SPSS version 17 and the Chi-square test was applied to analyze the qualitative data. Results: At least one RF for CVD was present in all the subjects, with majority (93.6% of them having at least two RFs. The presence of the RFs (moderate to high, 3–11 was found to be significantly associated with lower income group, unskilled workers, migration year <1, alcoholics, personal tobacco use, family history of tobacco use, and the low knowledge score regarding tobacco use (0–2. Conclusions: Community-based comprehensive behavioral and life style communication package should be established for workers to reduce the modifiable RFs of CVD.

    There is little information on the private lives of women engaged in sex work, particularly how power dynamics within intimate relationships may affect intimate partner violence (IPV). Using baseline data of sex workers enrolled in a longitudinal cohort, "An Evaluation of Sex Workers' Health Access" (AESHA), the present study examined the association between sexual relationship power and IPV among sex workers in non-commercial partnerships in Vancouver, Canada. Pulweritz's Sexual Relationship Power Scale (SRPS) and The World Health Organization (WHO) Intimate Partner Violence against Women Scale (Version9.9) were used. Bivariable and multivariable logistic regression techniques were used to investigate the potential confounding effect of sexual relationship power on IPV among sex workers. Adjusted odds ratios (AOR) and 95% confidence intervals (CIs) were reported. Of 510 sex workers, 257 (50.4%) reported having an non-commercial intimate partner and were included in this analysis. In the past 6 months, 84 (32.7%) sex workers reported IPV (physical, sexual or emotional). The median age was 32 years, 39.3% were of Aboriginal ancestry, and 27.6% were migrants. After controlling for known confounders (e.g., age, Aboriginal ancestry, migrant status, childhood trauma, non-injection drug use), low relationship power was independently associated with 4.19 increased odds (95% CI: 1.93-9.10) and medium relationship power was associated 1.95 increased odds (95% CI: 0.89-4.25) of IPV. This analysis highlights how reduced control over sexual-decision making is plays a critical role in IPV among sex workers, and calls for innovation and inclusive programming tailored to sex workers and their non-commercial intimate partnerships.

    This study explored perceived benefits and risks of participation in HIV research among 33 female sex workers in Tecun Uman, Guatemala. Stigma associated with sex work and HIV was a critical barrier to research participation. Key benefits of participation included access to HIV/STI prevention and testing, as well as positive and trusting relationships between sex workers and research teams. Control exerted by managers had mixed influences on perceived research risks and benefits. Results underscore the critical need for HIV investigators to develop population-tailored procedures to reduce stigma, engage managers, and reinforce trusting, reciprocal relationships between sex work communities and researchers.

    2012-01-01

    Sex in insects is determined by a cascade of regulators ultimately controlling sex-specific splicing of a transcription factor, Doublesex (Dsx). We recently identified homolog of dsx in the red flour beetle, Tribolium castaneum (Tcdsx). Here, we report on the identification and characterization of a regulator of Tcdsx splicing in T. castaneum. Two male-specific and one female-specific isoforms of T. castaneum transformer (Tctra) were identified. RNA interference-aided knockdown of Tctra in pupa or adults caused a change in sex from females to males by diverting the splicing of Tcdsx pre-mRNA to male-specific isoform. All the pupa and adults developed from Tctra dsRNA injected final instar larvae showed male-specific sexually dimorphic structures. Tctra parental RNAi caused an elimination of females from the progeny resulting in production of all male progeny. Transformer parental RNAi could be used to produce all male population for use in pest control though sterile male release methods. PMID:22924109

    Full Text Available Human and animal immune functions present sex dimorphism that seems to be mainly regulated by sex hormones. In the present study, the activities of the antioxidant enzymes total superoxide dismutase (SOD, catalase (CAT, and glutathione peroxidase (GSH-Px were measured in intraperitoneal resident macrophages from adult male and female rats. In addition to comparing males and females, we also examined the regulation of these enzyme activities in macrophages by sex steroids. GSH-Px activity did not differ between male and female macrophages. However, both total SOD and CAT activities were markedly higher in females than in males (83 and 180%. Removal of the gonads in both males and females (comparison between castrated groups increased the difference in SOD activity from 83 to 138% and reduced the difference in CAT activity from 180 to 86%. Castration and testosterone administration did not significantly modify the activities of the antioxidant enzymes in male macrophages. Ovariectomy did not affect SOD or GSH-Px activity but markedly reduced (48% CAT activity. This latter change was fully reversed by estrogen administration, whereas progesterone had a smaller effect. These results led us to conclude that differences in the SOD and CAT activities may partially explain some of the differences in immune function reported for males and females. Also, estrogen is a potent regulator of CAT in macrophages and therefore this enzyme activity in macrophages may vary considerably during the menstrual cycle.

    French Guiana is the French territory that is most affected by HIV. AIDS incidence is much higher than in mainland France and sex work seems to be an important driver of the epidemic. The objective of this study was to describe consistent condom use among female sex workers with their clients and their intimate partners and to identify determinants of non-use of condoms. An HIV/AIDS Knowledge, Attitudes, Behaviours and Practices survey was conducted in 2009-2010 among sex workers in French Guiana. A total of 477 sex workers were interviewed. Female sex workers were more likely to use condoms with their clients (97%) than with their intimate partners (45%). The factors associated with non-consistent condom use with the intimate partner were having had an abortion, feeling at risk for HIV, not evaluating one's own risk for HIV, living as a couple, being Dominican, and not feeling comfortable asking intimate partners to use condoms. Although a high proportion of female sex workers declared using condoms with commercial partners, there is still room for improvement in the prevention of transmission with both commercial and intimate partners. © The Author(s) 2014.

    Sex-selective abortion is expressly prohibited in Nepal, but limited evidence suggests that it occurs nevertheless. Providers' perspectives on sex-selective abortion were examined as part of a larger study on legal abortion in the public sector in Nepal. In-depth interviews were conducted with health care providers and administrators providing abortion services at four major hospitals (n = 35), two in the Kathmandu Valley and two in outlying rural areas. A grounded theory approach was used to code interview transcripts and to identify themes in the data. Most providers were aware of the ban on sex-selective abortion and, despite overall positive views of abortion legalization, saw sex selection as an increasing problem. Greater availability of abortion and ultrasonography, along with the high value placed on sons, were seen as contributing factors. Providers wanted to perform abortions for legal indications, but described challenges identifying sex-selection cases. Providers also believed that illegal sex-selective procedures contribute to serious abortion complications. Sex-selective abortion complicates the provision of legal abortion services. In addition to the difficulty of determining which patients are seeking abortion for sex selection, health workers are aware of the pressures women face to bear sons and know they may seek unsafe services elsewhere when unable to obtain abortions in public hospitals. Legislative, advocacy, and social efforts aimed at promoting gender equality and women's human rights are needed to reduce the cultural and economic pressures for sex-selective abortion, because providers alone cannot prevent the practice.

    There is growing interest in the ways in which legal and human rights issues related to sex work affect sex workers' vulnerability to HIV and abuses including human trafficking and sexual exploitation. International agencies, such as UNAIDS, have called for decriminalisation of sex work because the delivery of sexual and reproductive health services is affected by criminalisation and social exclusion as experienced by sex workers. The paper reflects on the connections in various actors' framings between sex workers sexual and reproductive health and rights (SRHR) and the ways that international law is interpreted in policing and regulatory practices. The literature review that informs this paper was carried out by the authors in the course of their work within the Paulo Longo Research Initiative. The review covered academic and grey literature such as resources generated by sex worker rights activists, UN policy positions and print and online media. The argument in this paper has been developed reflectively through long term involvement with key actors in the field of sex workers' rights. International legislation characterises sex work in various ways which do not always accord with moves toward decriminalisation. Law, policy and regulation at national level and law enforcement vary between settings. The demands of sex worker rights activists do relate to sexual and reproductive health but they place greater emphasis on efforts to remove the structural barriers that limit sex workers' ability to participate in society on an equal footing with other citizens. There is a tension between those who wish to uphold the rights of sex workers in order to reduce vulnerability to ill-health and those who insist that sex work is itself a violation of rights. This is reflected in contemporary narratives about sex workers' rights and the ways in which different actors interpret human rights law. The creation of regulatory frameworks around sex work that support health, safety

    Background Violence against female sex workers (FSWs) has been increasingly reported as an important determinant of HIV infection risk. This study explores the frequency of different violent experiences (sexual abuse, rejection, beating and imprisonment) among FSWs in Argentina and its association with condom use and HIV and T. pallidum prevalence. Methods A convenience sample of 1255 FSWs was included in a cross-sectional study conducted between October 2006 and November 2009. Results Sexual abuse was reported by 24.1% (219/907) of women. A total of 34.7% (42/1234) reported rejection experiences, 21.9% (267/1215) reported having been beaten and 45.4% (561/1236) stated having been arrested because of their sex work activity. There was a higher frequency of inconsistent condom use with clients among FSWs who had experienced sexual abuse, rejection, and police detention. A higher frequency of HIV and T. pallidum infection was detected among FSWs who reported having been arrested by the police. Conclusion The study shows for the first time the frequency of different violent situations among FSWs in Argentina. The association between violence against sex workers, condom use and STI prevalence demonstrated here calls for measures to reduce stigma and violence against FSWs. Such violent experiences may increase vulnerability to STI through coerced unprotected sex. PMID:23342092

    Men are less likely to seek help for mental health problems, possibly because of stigma imposed by cultural masculine norms. These tendencies may be amplified within male-dominated workplaces such as the emergency services or transport industries. Mobile apps present a promising way to provide access to mental health support. However, little is known about the kinds of mental health technologies men would be willing to engage with, and no app can be effective if the intended users do not engage with it. The goal of this participatory user research study was to explore the perceptions, preferences, and ideas of workers in male-dominated workplaces to define requirements for a mental health app that would be engaging and effective at improving psychological well-being. Workers from male-dominated workplaces in rural, suburban, and urban locations took part in an exploratory qualitative study involving participatory workshops designed to elicit their perspectives and preferences for mental health support and the design of an app for mental health. Participants generated a number of artifacts (including draft screen designs and promotional material) designed to reify their perceptions, tacit knowledge, and ideas. A total of 60 workers aged between 26 and 65 years, 92% (55/60) male, from male-dominated workplaces in rural (16/60, 27%), suburban (14/60, 23%), and urban (30/60, 50%) locations participated in one of the 6 workshops, resulting in 49 unique feature ideas and 81 participant-generated artifacts. Thematic analysis resulted in a set of feature, language, and style preferences, as well as characteristics considered important by participants for a mental health app. The term "mental health" was highly stigmatized and disliked by participants. Tools including a mood tracker, self-assessment, and mood-fix tool were highly valued, and app characteristics such as brevity of interactions, minimal on-screen text, and a solutions-oriented approach were considered

    To assess the health statue of chronically exposed Chinese medical radiation workers. A cross-sectional study of 530 medical radiation workers in a city of China was conducted to document the health status and the monitored annually absorbed doses. Long-term and low-dose radiation exposure can affect a number of health indicators in the individuals, which covered the cardiovascular system, hematologic system, ophthalmology, liver and kidney s functions, chromosome aberration and micronucleus. The differences in the health status between male and female individuals were associated with job types and exposed years of service. The monitored doses of individuals were lower than the limit value of the national standard. The health status in chronically exposed individuals demonstrated some gender difference associated with length of exposure and work type. This study provides some evidence to understand the health status of medical radiation workers in China and have the potentially to inform screening and clinical diagnosis. (authors)

  10. Ground-breaking research into Ghanaian sex-workers suggests high awareness. Country surveys.

    Science.gov (United States)

    1996-02-01

    The first nationwide research into prostitution in Ghana has been completed by Dr. Matilida Pappoe. She has found that there has been exponential growth in prostitution over the past three years in the country. While 10 years ago, people would not openly talk about prostitution, now that people's friends are increasingly entering the trade, people freely discuss prostitution. The research indicates that this growth is linked to the negative effects of macroeconomic policies aimed at economic growth, such as structural adjustment. For example, 39 of 121 sex workers studied claimed to have begun working as a prostitute after their trading businesses collapsed. Study findings suggest a high level of AIDS awareness among Ghanaian prostitutes. Prostitutes in Ghana are considered to be either seaters or roamers. Seaters are a loosely organized group of women who tend to work from a common compound, attracting customers by sitting in the doorway of their rooms. They typically report to an older retired sex worker who settles disputes and raises credit if one of the women must pay a police fine. Seaters are largely 30-45 years old and work in industrial centers. Roamers, however, tend to be 20-30 years old, work in coastal towns, and are usually better educated. They move from place to place and are probably at lower risk of contracting HIV due to the higher rates they charge and the correspondingly lower number of clients they entertain. Roamers seem to have higher rates of condom use and clients who are aware of the dangers. Roamers, too, are not organized as a group and may even often be highly competitive. Their work in the isolation of hotels makes them particularly vulnerable. Economic necessity has therefore increasingly drawn Ghanaian women into the sex trade, while Ghanaian men who typically support two or three women in exchange for sex, but can no longer do so due to current economic conditions, turn to occasional sex with prostitutes. This paper notes that

    Objective: To investigate the current status of HIV infection and the related factors in HIV antibody positive clients of female sex workers (FSWs) recently reported in Shaanxi province. Methods: The HIV/AIDS cases newly diagnosed in males living in Shaanxi from January 1th of 2013 to June 30th of 2014 were selected and those infected through " commercial heterosexual behavior" were identified. The information about their demographic characteristics, previous unprotected heterosexual sex and the sample sources were collected, and serum or plasma samples were collected from them and tested with BED-CEIA. The proportion of recent HIV infections and associated factors were investigated. Results: The proportion of recent HIV infection and HIV-antibody detection rate in 212 HIV antibody positive male clients of FSWs were 25.5% and 6.6% respectively. The cases who had the educational level of junior middle school or high middle school were wore likely to have long term HIV infections than those with lower educational level (a OR =0.28, 95 % CI : 0.08-0.93). Compared with patients identified by hospitals or sexually transmitted diseases clinics, recent HIV infections were more likely to be found through preoperative test or blood transfusion test (a OR =3.14, 95 % CI : 1.06-9.30) and blood donation test (a OR =4.19, 95 % CI :1.01-17.42). Compared with the cases who had commercial sex only in Xi' an or other province or both in Xi' an and other province, the cases who had commercial sex in other cities in Shaanxi were more likely to be infected recently (a OR =0.19, 95 %CI : 0.07-0.57). Compared with the cases had temporary heterosexual sex partner, those who had no temporary sex partners were more likely to be infected recently (a OR =9.03, 95 % CI : 3.00-27.18) ( P HIV infections among HIV antibody positive clients of FSWs was high and the HIV-antibody detection rate among them was low.

    Full Text Available Peer-led outreach is a critical element of HIV and STI-reduction interventions aimed at sex workers. We study the association between peer-led outreach to sex workers and the time to utilize health facilities for timely STI syndromic-detection and treatment. Using data on the timing of peer-outreach interventions and clinic visits, we utilize an Extended Cox model to assess whether peer educator outreach intensity is associated with accelerated clinic utilization among sex workers.Our data comes from 2705 female sex workers registered into Pragati, a women-in-sex-work outreach program, and followed from 2008 through 2012. We analyze this data using an Extended Cox model with the density of peer educator visits in a 30-day rolling window as the key predictor, while controlling for the sex workers' age, client volume, location of sex work, and education level. The principal outcome of interest is the timing of the first voluntary clinic utilization.More frequent peer visit is associated with earlier first clinic visit (HR: 1.83, 95% CI, 1.75-1.91, p < .001. In addition, 18% of all syndrome-based STI detected come from clinic visits in which the sex worker reports no symptoms, underscoring the importance of inducing clinic visits in the detection of STI. Additional models to test the robustness of these findings indicate consistent beneficial effect of peer educator outreach.Peer outreach density is associated with increased likelihood of-and shortened duration to-clinic utilization among female sex workers, suggesting potential staff resourcing implications. Given the observational nature of our study, however, these findings should be interpreted as an association rather than as a causal relationship.

    This study explores the narratives of psychological distress and resilience among a group of female sex workers who use residential spaces to attend to clients in rural India. The narratives reflect the lived experiences of these women. They describe the women's reasons for opting into sex work; guilt, shame, and stigma related to their sex worker status; experiences with intimate partner and domestic violence; health-related problems; communication with their family members about their sex worker status; mental health referral practices among the women; and elements of resilience and strength that they experience within themselves and within their community of fellow sex workers. The article also offers elements of our own experiences of recruiting the women to participate in the focus group, training local outreach workers in conducting focus group discussions, and forging a collaboration with a local community-based organization to highlight important barriers, challenges, and strategies for planning a group-based discussion to explore the mental health needs of home-based sex workers. © 2016 Wiley Periodicals, Inc.

    Issue addressed The smoking rate among male Chinese migrants in Australia is higher than among the general population. This study investigated the smoking rate of male Chinese restaurant workers in metropolitan Sydney, and explored factors associated with smoking and quitting. Methods A self-administered questionnaire survey was completed by Chinese workers in selected Chinese restaurants in metropolitan Sydney from October-December 2012. Eighty-nine Chinese restaurants were approached and 54 (61%) took part in the study. The questionnaire asked participants about their smoking status, knowledge of and attitudes to smoking and quitting as well as socio-demographic information. Multivariable logistic regression was built to assess the associated factors. Results Of the 382 participants who completed the survey, 171 (45%) were current smokers and 50% of current smokers wanted to quit smoking. Participants who spoke Mandarin, had lower English proficiency, did not realise environmental smoke harms children, did not prefer a smoke-free environment or had more than 50% of relatives or friends who smoked were more likely to be current smokers. Participants who were aged 18-29 years, did not understand the benefits of quitting smoking or did not prefer a smoke-free environment were less likely to want to quit. Conclusions Nearly 50% of male Chinese restaurant workers surveyed in this study were current smokers. Key factors associated with the participants' smoking or quitting status are: aged 18-29 years; speaking Mandarin; lower English literacy; and not knowing the dangers of smoking. So what? Tobacco control programs targetted at male Chinese restaurant workers that raise awareness of the harm caused by smoking and the benefits of quitting smoking are required to enhance intention to quit smoking within this population.

    This paper uncovers 'conspicuous work' as a new form of status seeking that can explain social interactions in labour supply. We analyse how peer working time relates to both labour supply and happiness for Dutch male workers. Using a unique measure of peer weekly working time, we find that men's working time increases with that of their peers and that peer working time is negatively related to men's happiness. These findings are consistent with a 'conspicuous work' model, in which individual...

    Background: The spread of HIV infection among men in Indonesia continues to increase every year. Clients of female sex workers (FSWs) are a group at higher risk of acquiring HIV infection due to their frequent engagement in sexual acts with sex workers. This study aimed to identify factors of susceptibility to HIV infection among clients of FSWs. Methods: A qualitative inquiry using one-on-one in-depth interviews was conducted in the Belu and Malaka districts of Indonesia from January to April 2017. The study participants (n =42) were the clients of FSWs recruited using the snowball sampling technique. The inclusion criteria were: being a client of FSWs and being aged 18 years or more. Data were analysed using a framework analysis. Results: Findings were grouped into two main emerging themes that included behavioural and socioeconomic factors. Behavioural factors that mediated HIV susceptibility among clients of FSWs were: frequent engagement in unsafe sex with multiple sex workers; low perceptions of the relevance of available HIV and AIDS services and limited access to these services; and HIV stigma or fear of being labelled as HIV positive. Socioeconomic factors included: participants' economic situation; and individuals' household responsibility and ability to afford FSWs services. Conclusions: The study results indicate the need to reformulate and improve HIV and AIDS-related services, including increasing the level of availability of HIV service points and the dissemination of knowledge and information about HIV and AIDS and condom use and making them accessible to both FSWs and their clients in Belu and Malaka districts.

    The Ussuri catfish Pseudobagrus ussuriensis is a promising aquaculture fish with sexual dimorphism that males grow 2-3 times faster than females. Therefore, all-male breeding could increase production of this fish, and sex-linked markers would be useful during the breeding process. In this study, a male-associated marker named PuGT54 was isolated in P. ussuriensis from a previously constructed microsatellite library. A total of 185 P. ussuriensis individuals containing 95 females and 90 males were used to test the usage of this maker. And results showed that sexes of all individuals were successfully identified, indicating the high reliability and accuracy of this marker for sex identification. Furthermore, the male-specific fragment amplified by this maker was cloned and sequenced, which was 118 base pairs in length. As homologous genes of this fragment was not found through BLASTn, detailed information of the male-specific fragment is unknown presently. Nevertheless, this marker would be helpful in conservation, breeding and ecological study of P. ussuriensis.

    Full Text Available Social and structural influences of condom negotiation among female sex workers (FSWs remain understudied. This study assesses environmental and individual factors associated with condom negotiation among FSWs at high risk for acquiring HIV in a large urban setting of Metro Manila, Philippines.Female bar/spa workers (N = 498, aged 18 and over, underwent interview-led surveys examining their sexual health practices in the context of their risk environments. Data were collected from April 2009-January 2010 from 54 venues. Multiple logistic regressions were conducted to assess socio-behavioral factors (e.g., age, education, length of time employed as an entertainer, and alcohol/drug use and socio-structural factors (e.g., venue-level peer/manager support, condom rule/availability, and sex trafficking associated with condom negotiation, adjusting for individuals nested within venues.Of 142 FSWs who traded sex in the previous 6 months (included in the analysis, 24% did not typically negotiate condom use with venue patrons. Factors in the physical environment--trafficked/coerced into work (AOR = 12.92, 95% CI = 3.34-49.90, economic environment--sex without a condom to make more money (AOR = 1.52, 95% CI 1.01-2.30, policy environment--sex without a condom because none was available (AOR = 2.58, 95% CI = 1.49-4.48, and individual risk--substance use (AOR = 2.36, 95% CI = 1.28-4.35 were independently associated with FSWs' lack of condom negotiation with venue patrons.Factors in the physical, economic, and policy environments, over individual (excepting substance use and social level factors, were significantly associated with these FSWs' condom negotiations in the Philippines. Drawing upon Rhodes' risk environment framework, these results highlight the need for policies that support safer sex negotiations among sex workers in the context of their risk environments. Interventions should reduce barriers to condom negotiation

    Almost all animals show sex differences in body size. For example, in Drosophila, females are larger than males. Although Drosophila is widely used as a model to study growth, the mechanisms underlying this male-female difference in size remain unclear. Here, we describe a novel role for the sex determination gene transformer (tra) in promoting female body growth. Normally, Tra is expressed only in females. We find that loss of Tra in female larvae decreases body size, while ectopic Tra expression in males increases body size. Although we find that Tra exerts autonomous effects on cell size, we also discovered that Tra expression in the fat body augments female body size in a non cell-autonomous manner. These effects of Tra do not require its only known targets doublesex and fruitless. Instead, Tra expression in the female fat body promotes growth by stimulating the secretion of insulin-like peptides from insulin producing cells in the brain. Our data suggest a model of sex-specific growth in which body size is regulated by a previously unrecognized branch of the sex determination pathway, and identify Tra as a novel link between sex and the conserved insulin signaling pathway.

    To date, there is limited published data on same-sex male couples and single men using assisted reproduction treatment to build their families. The objective of this retrospective study was to better understand treatment considerations and outcomes for this population when using assisted reproduction treatment. A total of 37 same-sex male couples and eight single men (seven homosexual and one heterosexual) who attended the CReATe Fertility Centre for assisted reproduction services were studied. There was a 21-fold increase in the number of same-sex male couples and single men undergoing assisted reproduction treatment since 2003. The mean age was 46years (24-58). Twenty-eight couples (76%) chose to use spermatozoa from both partners to fertilize their donated oocytes. Most men (32 same-sex male couples and seven single men; 87%) obtained oocytes from an anonymous donor, whereas five couples and one single man (13%) had a known donor. Anonymous donors who were open to be contacted by the child after the age of 18 were selected by 67% of patients. Of all 25 deliveries, eight (32%) were sets of twins. All of the twins were half genetic siblings. Copyright © 2013 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Peroxisome proliferator-activated receptor gamma (PPAR activation decreased serum testosterone (T in women with hyperthecosis and/or polycystic ovary syndrome and reduced the conversion of androgens to estradiol (E2 in female rats. This implies modulation of female sex steroid hormones by PPAR. It is not clear if PPAR modulates sex steroid hormones in diabetic males. Because PPAR activation by thiazolidinedione increased insulin sensitivity in type 2 diabetes, understanding the long term impact of PPAR activation on steroid sex hormones in males is critical. Our objective was to determine the effect of PPAR activation on serum and intratesticular T, luteinizing hormone (LH, follicle stimulating hormone (FSH and E2 concentrations in male Zucker diabetic fatty (ZDF rats treated with the PPAR agonist rosiglitazone (a thiazolidinedione. Treatment for eight weeks increased PPAR mRNA and protein in the testis and elevated serum adiponectin, an adipokine marker for PPAR activation. PPAR activation did not alter serum or intratesticular T concentrations. In contrast, serum T level but not intratesticular T was reduced by diabetes. Neither diabetes nor PPAR activation altered serum E2 or gonadotropins FSH and LH concentrations. The results suggest that activation of PPAR by rosiglitazone has no negative impact on sex hormones in male ZDF rats.

    Public concern is growing about the exposure to electromagnetic fields (EMF) and its effect on male reproductive health. Detrimental effect of EMF exposure on sex hormones, reproductive performance and sex-ratio was reported. The present study was designed to clarify whether paternal exposure to electromagnetic pulse (EMP) affects offspring sex ratio in mice. 50 male BALB/c mice aged 5-6 weeks were exposed to EMP daily for 2 weeks before mated with non-exposed females at 0d, 7d, 14d, 21d and 28d after exposure. Sex hormones including total testosterone, LH, FSH, and GnRH were detected using radioimmunoassay. The sex ratio was examined by PCR and agarose gel electrophoresis. The results of D0, D21 and D28 showed significant increases compared with sham-exposed groups. The serum testosterone increased significantly in D0, D14, D21, and D28 compared with sham-exposed groups (p<0.05). Overall, this study suggested that EMP exposure may lead to the disturbance of reproductive hormone levels and affect the offspring sex ratio. Copyright © 2017. Published by Elsevier B.V.

    The purpose of this study was to understand the actual state of life hours (working time, sleep time, and time of meal intake) and dietary habits of male shift work employees, and to elucidate the impact of working arrangements and dietary habits on their physical condition and health problems. The subjects were 187 male employees (aged 18-64 years) working for an industrial company in Toyama prefecture. We used a self-administered questionnaire to assess dietary habit, lifestyle habits, and life hours at the time of a periodic health examination in April 2013. The subjects were grouped based on their working condition (i.e., day shift, late shift, and late-night shift) into two groups of day shift (n = 107) and shiftwork (n = 80). The proportion of time spent sleeping and feeding was determined in half hour increments, and the incidences of skipping meals (breakfast, lunch and dinner) and midnight snack intake were calculated for each working condition. We also examined the association between the frequency of eating and physical condition for each working condition. The state of life hours of the shiftwork group during the day was similar to that of the day shift group. However, the workers' state of life hours, incidences of skipping meals, and midnight snack intake varied considerably when working at the other shift times. In the shiftwork group, regardless of the working patterns, the BMI and % body fat of the group that ate more than three times a day were significantly lower than those of the group that ate less than twice a day. The results of the present study suggest that it is difficult to ensure the time and opportunity for meals for shift workers. We consider that it is necessary to prevent them skipping of meals, and to support a proper dietary intake during the night.

    This research aimed to determine the effect of food insecurity on sexual HIV risk with clients among youth sex workers (YSWs) sex workers (2010-2013). We examined the independent relationship between YSWs' food insecurity and being pressured into sex without a condom by clients ("client condom refusal"). Of 220 YSWs, 34.5 % (n = 76) reported client condom refusal over the 3.5-year study period and 76.4 % (n = 168) reported any food insecurity. Adjusting for other HIV risk pathways, food insecurity retained an independent effect on client condom refusal (AOR 2.08, 95 % CI 1.23-3.51), suggesting that food insecurity is significantly associated with HIV risk among YSWs. This study indicates a critical relationship between food insecurity and HIV risk, and demonstrates YSWs' particular vulnerability. Public policies for food assistance as a harm reduction measure may be key to addressing this disparity.

  12. Gadd45g is essential for primary sex determination, male fertility and testis development.

    Directory of Open Access Journals (Sweden)

    Heiko Johnen

    Full Text Available In humans and most mammals, differentiation of the embryonic gonad into ovaries or testes is controlled by the Y-linked gene SRY. Here we show a role for the Gadd45g protein in this primary sex differentiation. We characterized mice deficient in Gadd45a, Gadd45b and Gadd45g, as well as double-knockout mice for Gadd45ab, Gadd45ag and Gadd45bg, and found a specific role for Gadd45g in male fertility and testis development. Gadd45g-deficient XY mice on a mixed 129/C57BL/6 background showed varying degrees of disorders of sexual development (DSD, ranging from male infertility to an intersex phenotype or complete gonadal dysgenesis (CGD. On a pure C57BL/6 (B6 background, all Gadd45g(-/- XY mice were born as completely sex-reversed XY-females, whereas lack of Gadd45a and/or Gadd45b did not affect primary sex determination or testis development. Gadd45g expression was similar in female and male embryonic gonads, and peaked around the time of sex differentiation at 11.5 days post-coitum (dpc. The molecular cause of the sex reversal was the failure of Gadd45g(-/- XY gonads to achieve the SRY expression threshold necessary for testes differentiation, resulting in ovary and Müllerian duct development. These results identify Gadd45g as a candidate gene for male infertility and 46,XY sex reversal in humans.

    To identify factors associated with time to initiation of (i) sex work prior to injecting drugs initiation; (ii) injection drug use prior to sex work initiation; and (iii) concurrent sex work and injection drug use (i.e. initiated at the same age) among female sex workers who currently inject drugs (FSW-IDU). Parametric survival analysis of baseline data for time to initiation event. Tijuana and Ciudad Juarez situated on the Mexico-US border. A total of 557 FSW-IDUs aged ≥18 years. Interview-administered surveys assessing context of sex work and injection drug use initiation. Nearly half (n = 258) initiated sex work prior to beginning to inject, a third (n = 163) initiated injection first and a quarter (n = 136) initiated both sex work and injection drug use concurrently. Low education and living in Ciudad Juarez accelerated time to sex work initiation. Being from a southern Mexican state and initiating drug use with inhalants delayed the time to first injection drug use. Having an intimate partner encourage entry into sex work and first injecting drugs to deal with depression accelerated time to initiating sex work and injection concurrently. Early physical abuse accelerated time to initiating sex work and injection, and substantially accelerated time to initiation of both behaviors concurrently. Among female sex workers who currently inject drugs in two Mexican-US border cities, nearly half appear to initiate sex work prior to beginning to inject, nearly one-third initiate injection drug use before beginning sex work and one-quarter initiate both behaviors concurrently. Predictors of these three trajectories differ, and this provides possible modifiable targets for prevention. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.
