    Background HIV prevalence varies between 0.9 and 6.5% in Ethiopia’s eleven regions. Little has been published examining the reasons for this variation. Methods We evaluated the relationship between HIV prevalence by region and a range of risk factors in the 2005 and 2011 Ethiopian Demographic Health Surveys. Pearson’s correlation was used to assess the relationship between HIV prevalence and each variable. Results There was a strong association between HIV prevalence and three markers of sexual risk: mean lifetime number of partners (men: r = 0.87; P cohabiting partner (men: r = 0.92; P premarital sex. Condom usage and HIV testing were positively associated with HIV prevalence, while the prevalence of circumcision, polygamy, age at sexual debut and male migration were not associated with HIV prevalence. Conclusion Variation in sexual behavior may contribute to the large variations in HIV prevalence by region in Ethiopia. Population-level interventions to reduce risky sexual behavior in high HIV incidence regions should be considered. PMID:26496073

    Full Text Available The present paper examined the prevalence and psychosocial correlates of adolescent deliberate self-harm (DSH and suicidal behavior in a representative sample of 3,328 secondary school students in Hong Kong. With reference to the previous year, 32.7% of the students reported at least one form of DSH, 13.7% of the respondents had suicide thoughts, 4.9% devised specific suicidal plans, and 4.7% had actually attempted suicide. Adolescent girls had significantly higher rates of DSH and suicidal behavior than did adolescent boys. Having remarried parents was related to an increased likelihood of DSH and suicide. While high levels of family functioning, overall positive youth development, and academic and school performance predicted low rates of DSH and suicidal behavior, cognitive and behavioral competencies were unexpectedly found to be positively associated with DSH and suicidal behavior. Theoretical and practical implications of the findings are discussed.

    Bullying among school-aged youth is a common issue worldwide and is increasingly being recognized as an important problem affecting both victims and perpetrators. Most of the bullying studies have been conducted in western countries, and their implications in other regions are limited due to different cultural contexts. The goal of our study is to identify the prevalence of bullying and its correlates school-aged youth in Guangdong province. In total, 1098 (7.1%) students reported having bullied other students, 744 (4.8%) students reported having been bullied by other students and 396 (2.6%) students reported having both bullied other students and been bullied by other students. There was a strong association between bullying others as well as being bullied and suicidal ideations, suicidal attempts, and self-harm behaviors. The prevalence of bullying and its associations with delinquent behaviors warrant the importance of school facility based preventive intervention taking into account both victims and perpetrators.

    Full Text Available Abstract Background In China, sexual health and behaviors of young people have become a growing public concern but few studies have been conducted to investigate the prevalence and psychosocial correlates of the phenomenon. Methods A self-reported questionnaire survey on youth sexual behaviors was conducted among 1,500 university students in 2011 at Hefei, a middle-size city in eastern China. A total of 1,403 students (age = 20.30 ± 1.27 years completed the questionnaire with a high response rate of 93.5%. Results Among the respondents, 12.6% (15.4% of male versus 8.6% of female students reported having pre-marital heterosexual intercourse; 10.8% (10.5% of males versus 11.2% females had oral sex; 2.7% (3.4% of males versus 1.7% females reported same-sex activities; 46% (70.3% of males versus 10.8% of females reported masturbation behaviors; 57.4% (86.2% of males versus 15.6% females students viewed pornography. In terms of sexual communication about sexual knowledge acquisition, 13.7% (10.7% of males versus 18% of females talked to their parents about sex; 7.1% (6.1% of males versus 8.4% of females students reported having conversation with parents on contraception. About forcing sexual behavior, 2.7% (4% of males versus 0.9% of females reported forcing their sexual partners to have sex, and 1.9% (2.4% of males versus 1.2% of females reported being forced to have sex. Gender was found to be significant predictor of sexual behaviors in university students: males reported more sexual behaviors including sexual fantasy, heterosexual intercourse, masturbation, viewing pornography and talking about sex with friends. Several correlates of sexual behaviors were identified for students of different gender separately. For males, having romantic relationships, past sex education experiences, low educational aspirations, time spent on the Internet, and urban native settings were significantly associated with more sexual behaviors. For female students

    Abstract Objective: To determine the students’ exposure to four different sedentary behavior (SB) indicators and their associations with gender, grade, age, economic status and physical activity level. Methods: A cross-sectional study was conducted in 2013. The SB was collected using the HELENA instrument, composed by screen time questions (TV, video games and internet) and sitting activities on school opposite shift. The cut point of ≥2h/day was used to categorize the outcome. The Poisson regression was used for associations between the outcome and the independent variables (95% significance level), controlling for confounding variables and the possible design effect. Results: The sample was composed by 8661 students. The overall prevalence of SB was 69.2% (CI95% 68.1–70.2) on weekdays, and 79.6% (CI95% 78.7–80.5) on weekends. Females were more associated with the outcome, except to electronic games. Advanced grades students were more involved in sitting tasks when compared to the early grades. Older students were more likely to surf on net for ≥2h/day. Higher economic level students were more likely to engage in video games and internet. Active individuals were less likely to engage in SB on weekdays. Conclusions: The prevalence of SB was high, mainly on weekends. The associations with sex, age, grade and physical activity level should be considered into elaboration of more efficient interventions on SB control. PMID:26826878

    Fishermen in Southeast Asia have been found to be highly vulnerable to HIV, with research evidence highlighting the role of sexual risk behaviors. This study aims to estimate the rate of HIV as well as hepatitis C virus (HCV) infections among Malaysian fishermen, and the risky sexual and injection drug use behaviors that may contribute to these infections. The study also includes an assessment of socio-demographic, occupational and behavioral correlates of testing positive for HIV or HCV, and socio-demographic and occupational correlates of risk behaviors. The study had a cross-sectional design and recruited 406 fishermen through respondent-driven sampling (RDS). Participants self-completed a questionnaire and provided biological specimens for HIV and HCV testing. We conducted and compared results of analyses of both unweighted data and data weighted with the Respondent-Driven Sampling Analysis Tool (RDSAT). Of the participating fishermen, 12.4% were HIV positive and 48.6% had HCV infection. Contrary to expectations and findings from previous research, most fishermen (77.1%) were not sexually active. More than a third had a history of injection drug use, which often occurred during fishing trips on commercial vessels and during longer stays at sea. Of the fishermen who injected drugs, 42.5% reported unsafe injection practices in the past month. Reporting a history of injection drug use increased the odds of testing HIV positive by more than 6 times (AOR = 6.22, 95% CIs [2.74, 14.13]). Most fishermen who injected drugs tested positive for HCV. HCV infection was significantly associated with injection drug use, being older than 25 years, working on a commercial vessel and spending four or more days at sea per fishing trip. There is an urgent need to strengthen current harm reduction and drug treatment programs for Malaysian fishermen who inject drugs, especially among fishermen who work on commercial vessels and engage in deep-sea fishing.

    Full Text Available Abstract Background The adoption of health-related behaviors is an important part of adolescence. This study examined the prevalence and correlates of the isolated and simultaneous presence of behavioral risk factors for cardiovascular health (BRFCH among adolescents in Curitiba, Southern Brazil. Methods A cross-sectional study was performed with 1,628 adolescents (aged 11-17.9 years, 52.5% males that were randomly selected from 44 public schools. Self-report instruments were used to assess the variables. Six BRFCH were analyzed: insufficiently active, excessive TV watching, current alcohol and tobacco use, daily soft drinks consumption and inadequate fruit and vegetable consumption. Sociodemographic and behavioral variables were studied as possible correlates of the presence of BRFCH. Results The BRFCH with the highest prevalence were insufficiently active (50.5%, 95% confidence interval [95% CI]: 48.0-52.9 and daily soft drinks consumption (47.6%, 95% CI: 45.1-50.0. Approximately 30% of the adolescents presented three or more BRFCH simultaneously. Girls, adolescents who did not participate in organized physical activity, and who used computer/video games daily were the main high-risk subgroups for insufficiently active. Boys and those who used computer/video games daily were the high-risk subgroups for daily soft drinks consumption. For excessive TV watching, we identified to be at risk those who were from a high economic class, unemployed, and who used computer/video games daily. For current alcohol use, we identified older adolescents, who were from a high economic class and who worked to be at risk. Older adolescents, who worked and who spent little active time during a physical education class were the high-risk subgroups for current tobacco use. For inadequate fruit and vegetable consumption, we identified those who did not participate in organized physical activity to be at risk. Older adolescents, who were from a high economic class

    This study aims to examine the prevalence and sociodemographics, family and peer correlates of tattooing among high school students in southern Taiwan, and to examine the associations between tattooing and a variety of adolescent risk-taking behaviors and depression. A total of 9755 high school students (grades 7 to 12) in southern Taiwan were recruited into this study and completed the questionnaires. The prevalence of tattooing among the adolescents was calculated. The responses were analyzed using the logistic regression analysis models. It was found that 1% of high school students in southern Taiwan had 1 or more tattoos on their bodies. The older students who were perceived to have low family monitoring and who had friends who drink regularly, used illicit drugs, had a criminal record or were in a gang were more likely to have a tattoo. Tattooing was also found to be associated with violence, weekly alcohol consumption, illicit drug use, dropping out of school, unprotected sex, suicidal ideation/attempt, and depression. The results indicate that several demographics, family and peer factors are associated with adolescent tattooing. Tattooing may be an indicator of risk-taking behaviors in high school students.

    Eight-hundred and seventeen adolescent high school students in the Montreal region completed the DSM-IV-J gambling screen along with a questionnaire devised by the authors inquiring about their gambling behavior, including items assessing the types of activities in which they engage, frequency of involvement, reasons for gambling, and their cognitive perceptions of gambling activities. The results indicate that, in general, 80.2% of students reported having gambled during the previous year, with 35.1% gambling a minimum of once per week. Adolescents reported participating in gambling behavior more often than any other addictive behavior, including cigarette smoking, alcohol consumption, and illicit drug use. The mean age of onset of gambling behavior for the sample was 11.5 years. The rate of pathological gambling was 4.7% as measured by the DSM-IV-J. Pathological gamblers were more likely to have parents with gambling problems and to be engaging in illegal activities than non-pathological gamblers. Gender differences were evident, with males engaging in gambling activities more than females. Differences in game preferences were found, with males more attracted to sports lottery tickets and sports pool betting and females more attracted to lottery tickets and bingo. Gambling awareness and prevention issues are addressed.

    This study estimated smoking prevalence and identified factors associated with initiation among preteens in Nashville, TN. An anonymous, self-administrated questionnaire was given to 238 fifth- and sixth-graders in a middle-class neighborhood school. The mean age at initiation was 8.5 years (range 6-11 years). Overall, 10.5% of students had ever smoked; 16.1% of blacks and 9.3% of whites. Eighty-six percent continued to smoke. Black sixth-graders smoked (26.9%) four times the rate of black fifth-graders and 2.5 times that of white sixth-graders. Relatives initiated 78% of blacks while friends initiated 68% of whites. One-quarter of smokers got their cigarettes at home. Regular attendees of religious services had a lower smoking rate (6.9% versus 16.4%; p=0.01). Smoking rates decreased with increased knowledge of risks (p=0.00001). Among smokers, none believed that smoking is a risk factor for heart disease, 96% did not believe that smoking has any short-term health effects or is a risk factor for stroke. Few ever-smokers had a complete understanding of the health risks. Targeted messages and curriculum should be developed to teach preteens about the short- and long-term dangers of smoking. Clinicians can play a major role in educating their clients about the risks of smoking.

    ABSTRACT The purpose of the study was to investigate perceived teeth health status and oral health behavior, as well as their correlates, among adolescents in Cambodia. The analysis included 3806 Cambodian school children (mean age 15.7 years, SD=1.8 years) who took part in the “Global School-based Student Health Survey” (GSHS) in 2013. Overall, 7.8% of the students reported poor perceived teeth status, 18.0% had missed school in the past year because of a toothache, 26.7% engaged in combined oral health behavior (brushing teeth twice daily or more often = 79.8%, using fluoride toothpaste = 59.9%, and drinking soft drinks less than once a day = 53.6%), and 59.9% had never visited a dentist for a routine examination or other dental work. In the multivariate logistic regression analysis, older age, being female, missing school because of a toothache, having a toothache in the past 12 months, poor oral health behavior and sedentary leisure time were associated with poor perceived teeth status. Older age, good perceived teeth status, having had a dental check-up, washing hands before eating and after toilet use, and not eating fast food were associated with a positive oral health behavior (brushing teeth twice daily or more often, using fluoride toothpaste, and drinking soft drinks less than once a day). Significant proportions of poor perceived teeth status and poor oral health behavior were found among school children in Cambodia. Various risk factors (sociodemographic, dental variables, general health risk behaviors) for perceived poor teeth status, oral health behavior and never having had a dental check-up were identified, which can be utilized for intervention programs.

    These results suggest that snoring is associated with multiple factors in adolescents. We conclude that the prevalence of snoring is relatively high in children of this region. This highlights the need for awareness among physicians about the problem of sleep-disordered breathing, especially in children with asthma and obesity, and also the need for further studies to measure the prevalence of sleep breathing disorders among Iranians.

    Full Text Available Background. Syphilis is curable but Herpes Simplex Virus-2 (HSV-2 is not. As a result, the prevalence of syphilis but not HSV-2 may be influenced by the efficacy of national STI screening and treatment capacity. If the prevalence of syphilis and HSV-2 is found to be correlated, then this makes it more likely that something other than differential STI treatment is responsible for variations in the prevalence of both HSV-2 and syphilis. Methods. Simple linear regression was used to evaluate the relationship between national antenatal syphilis prevalence and HSV-2 prevalence in women in two time periods: 1990–1999 and 2008. Adjustments were performed for the laboratory syphilis testing algorithm used and the prevalence of circumcision. Results. The prevalence of syphilis was positively correlated with that of HSV-2 for both time periods (adjusted correlations, 20–24-year-olds: 1990–99: R2=0.54, P<0.001; 2008: R2=0.41, P<0.001 and 40–44-year-olds: 1990–99: R2=0.42, P<0.001; 2008: R2=0.49, P<0.001. Conclusion. The prevalence of syphilis and HSV-2 is positively correlated. This could be due to a common set of risk factors underpinning both STIs.

    Despite considerable controversy and speculation regarding sexting behaviour and its associated risks, to date there has been no integration and analysis of empirical literature on this topic. To collect and synthesise findings of the prevalence of sexting, its correlates, and the context in which it occurs, a systematic search of databases was conducted. Thirty-one studies, reporting on sexting prevalence and a diverse range of related variables, met inclusion criteria. The estimated mean prevalence weighted by sample size was calculated, with trends indicating sexting is more prevalent amongst adults than adolescents, older age is predictive of sexting for adolescents but not adults, and more individuals report receiving sexts than sending them. The correlates of sexting behaviour were grouped in terms of demographic variables, sexual and sexual risk behaviours, attitudes towards sexting, perceived outcomes of sexting, motivations for sexting, mental health and well-being variables, and attachment dimensions. Findings are discussed in terms of the trends indicated by the data, which provided substantiation that sexting behaviour is associated with numerous behavioural, psychological, and social factors. Limitations of the current research literature and future directions are also presented.

    Heart disease is one of the leading causes of morbidity and mortality worldwide and it has been well established that it is associated with both mental and physical conditions. This paper describes the prevalence of heart disease with mental disorders and other chronic physical conditions among the Singapore resident population. Data were from the Singapore Mental Health Study which was a representative, cross-sectional epidemiological survey undertaken with 6616 Singapore residents, between December 2009 and December 2010. The Composite International Diagnostic Interview Version 3.0 was used to establish the diagnosis of mental disorders, while a chronic medical conditions checklist was used to gather information on 15 physical conditions, including various forms of heart disease. Health-related quality of life was measured using the Euro-Quality of Life Scale (EQ-5D). The lifetime prevalence of heart disease was 2.8%. Socio-demographic correlates of heart disease included older age, Indian ethnicity, secondary education (vs. tertiary) and being economically inactive. After adjusting for socio-demographic variables and other comorbid physical and mental disorders, the prevalence of major depressive disorder and bipolar disorder were significantly higher among those with heart disease, as were diabetes, arthritis, kidney failure and lung disease. These findings highlight important associations between heart disease and various socio-demographic correlates, mental disorders and physical conditions. Given the high prevalence of mood disorders among heart disease patients, timely and appropriate screening and treatment of mental disorders among this group is essential.

    Eating pathology in Seasonal Affective Disorder (SAD) may be more severe than hyperphagia during winter. Although research has documented elevated rates of subclinical binge eating in women with SAD, the prevalence and correlates of binge eating disorder (BED) in SAD remain largely uncharacterized. We examined the prevalence and correlates of binge eating, weekly binge eating with distress, and BED as defined by the DSM-IV-TR in SAD. We also tested whether binge eating exhibits a seasonal pattern among individuals with BED. Two samples were combined to form a sample of individuals with SAD (N=112). A third sample included non-depressed adults with clinical (n=12) and subclinical (n=11) BED. All participants completed the Questionnaire of Eating and Weight Patterns-Revised (QEWP-R) and modified Seasonal Pattern Assessment Questionnaire (M-SPAQ). In the SAD sample, 26.5% reported binge eating, 11.6% met criteria for weekly binge eating with distress, and 8.9% met criteria for BED. Atypical symptom severity predicted binge eating and BED. In the BED sample, 30% endorsed seasonal worsening of mood, and 26% reported a winter pattern of binge eating. The spectrum of eating pathology in SAD includes symptoms of BED, which are associated with atypical depression symptoms, but typical depression symptoms.

    Full Text Available There are widespread differences in overweight/obesity prevalence in children, and understanding the reasons for this is very important. The present study aims: (I to conduct a meta-analysis on overweight/obesity prevalence in Portuguese children; (II to identify differences in biological and behavioural characteristics between normal-weight and overweight/obese children; and (III to investigate the importance of individual- and school-level correlates of variation in children’s BMI using multilevel modelling. A search was done for all published papers including Portuguese children during the last decade; further, 686 Portuguese children (9–11 years old were sampled and their BMI, family income, maturity offset, nutritional habits, physical activity, sedentariness, sleep time, and school environment information were collected. Results showed a stabilization of overweight/obesity during the last decade, 30.6% (95%CI: 0.287–0.34 for boys, 28.4% (95%CI: 0.23–0.35 for girls, and 30.3% (95%CI: 0.27–0.34 for boys and girls together. Differences between weight groups were only found in individual-level biological traits. The multilevel analysis did not identify significant contributions of school-level variables to children’s BMI variation. In conclusion, no increase was found in the prevalence of overweight/obesity among Portuguese children since 2000. Normal-weight and overweight/obese children only differ in individual-level characteristics, and school context variables were not related to variation in BMI.

    2013-01-01

    Most studies on HIV risk in sub-Saharan Africa focus on individual-level socio-demographic and behavioral correlates of risk. Only recently have researchers and programmers considered the context within which individuals live. This study uses the 2005–6 Zimbabwe Demographic and Health Survey to examine the correlation between the prevalence of HIV at the community level and the prevalence of HIV risk-taking behaviors. Results show that women and men living in communities with higher HIV prevalence in the opposite sex are at increased risk of HIV. In addition, rural women and men living in communities with greater premarital and non-marital sex are at greater risk of HIV. Finally, HIV prevalence is higher among women and men living in urban areas with higher intimate partner violence. Programs should address community-level social norms that make high-risk behaviors acceptable and thus increase all women and men’s risk of HIV, not just those engaged in high-risk behaviors.

    Depression among adolescents has been recognized as a major public health issue. The objective of this study was to determine the prevalence and correlates of depression among school-going adolescents in Malaysia. Data from the Malaysia Global School-based Health Survey (GSHS) 2012 were analyzed with additional data from the validated DASS21 (Depression, Anxiety, and Stress) questionnaire. The study revealed that 17.7% of respondents had depressive symptoms. Multivariate analysis further showed that feeling lonely (adjusted odds ratio [aOR] = 2.99; 95% CI = 2.57-3.47), Indian ethnicity (aOR = 2.00; 95% CI = 1.63-2.44), using drugs (aOR = 1.85; 95% CI = 1.21-2.82), and being bullied (aOR = 1.79; 95% CI = 1.60-1.99) were significantly associated with depressive symptoms. Lack of parental supervision, alcohol use, and tobacco use were also significant risk factors. Addressing depressive symptoms among adolescents may have implications for managing their risks of being bullied and substance use. This study also highlights the need to further investigate depressive symptoms among adolescents of Indian ethnicity.

    This study examined the prevalence of Internet addiction among college students in China and explored the correlations between Internet addiction and psychosocial factors. A total of 1,173 Chinese college students (62.1 percent males, Mage = 19.65 years) were invited to complete a questionnaire containing measures of demographic characteristics, psychosocial correlates, including the quality of the parent-child relationship, propensity for depression, and psychosocial competence, and Internet addictive behaviors. Among the participating students, 15.2 percent were classified as having Internet addiction. Furthermore, students who reported poorer parent-child relationships, higher levels of depression, and lower levels of psychosocial competence were more likely to report behaviors indicative of Internet addiction. Internet addiction was prevalent among college students in China. The significant predictors of Internet addiction were found to include the quality of the family environment (i.e., the quality of the parent-child relationship), personal mental health status (i.e., the existence of depression), and the level of developmental assets (i.e., psychosocial competence). These findings suggest that improving the quality of family life and promoting psychosocial competence among youth can be promising approaches for preventing or/and reducing Internet addiction among college students in China.

    Objectives The purpose of this study was to better understand the prevalence and correlates of substance use behaviors among HIV-infected adolescents in HIV care settings. Methods A cross-sectional sample of 2216 youth living with HIV (YLWH; ages 12-26) was recruited through the Adolescent Trials Network for HIV Interventions. Participants completed a one-time survey on sociodemographic factors, substance use and health behaviors. We used logistic regression models to understand the correlates of substance use outcomes. Results Overall, weekly or more frequent tobacco use was reported by 32.9% of participants, 27.5% marijuana use, and 21.3% alcohol use; and 22.5% reported any other illicit drug use. In multivariable models, young MSM had higher odds of reporting each substance use behavior, and transgender women had increased odds of marijuana and other illicit drug use. Criminal justice involvement, unstable housing, condomless sex, and suboptimal antiretroviral therapy was associated with increased risk of substance use behaviors. Conclusions Study findings highlight the need for regular screening for substance use in HIV care settings in order to improve access to and delivery of culturally competent substance use prevention and treatment services.

    Autism Spectrum Disorder affects up to 2.5% of children and is associated with harmful health outcomes (e.g. obesity). Low levels of physical activity and high levels of sedentary behaviors may contribute to harmful health outcomes. To systematically review the prevalence and correlates of physical activity and sedentary behaviors in children with Autism Spectrum Disorder, electronic databases (PsycINFO, SPORTDiscus, EMBASE, Medline) were searched from inception to November 2015. The review was registered with PROSPERO (CRD42014013849). Peer-reviewed, English language studies were included. Two reviewers screened potentially relevant articles. Outcomes of interest were physical activity and sedentary behaviour levels and their potential correlates. Data were collected and analysed in 2015. Of 35 included studies, 15 reported physical activity prevalence, 10 reported physical activity correlates, 18 reported sedentary behavior prevalence, and 10 reported sedentary behavior correlates. Estimates of children’s physical activity (34–166 mins/day, average 86 mins/day) and sedentary behavior (126–558 mins/day in screen time, average 271 mins/day; 428–750 mins/day in total sedentary behavior, average 479 mins/day) varied across studies. Age was consistently inversely associated, and sex inconsistently associated with physical activity. Age and sex were inconsistently associated with sedentary behavior. Sample sizes were small. All but one of the studies were classified as having high risk of bias. Few correlates have been reported in sufficient studies to provide overall estimates of associations. Potential correlates in the physical environment remain largely unexamined. This review highlights varying levels of physical activity and sedentary behavior in children with Autism Spectrum Disorder. Research is needed to consistently identify the correlates of these behaviors. There is a critical need for interventions to support healthy levels of these behaviors. PMID

    2016-09-01

    I describe early work on strongly correlated electron systems (SCES) from the perspective of a theoretical physicist who, while a participant in their reductionist top-down beginnings, is now part of the paradigm change to a bottom-up ‘emergent’ approach with its focus on using phenomenology to find the organizing principles responsible for their emergent behavior disclosed by experiment—and only then constructing microscopic models that incorporate these. After considering the organizing principles responsible for the emergence of plasmons, quasiparticles, and conventional superconductivity in SCES, I consider their application to three of SCES’s sister systems, the helium liquids, nuclei, and the nuclear matter found in neutron stars. I note some recent applications of the random phase approximation and examine briefly the role that paradigm change is playing in two central problems in our field: understanding the emergence and subsequent behavior of heavy electrons in Kondo lattice materials; and finding the mechanism for the unconventional superconductivity found in heavy electron, organic, cuprate, and iron-based materials.

    Full Text Available Abstract Background Several risk factors for alcohol and other substance use disorders (SUDs have been identified, but it is not well understood whether their associations with SUD are independent of each other. In particular, it is not well known, whether the associations between behavioral and affective factors and SUDs are independent of other risk factors. The incidence of SUDs peaks by young adulthood making epidemiological studies of SUDs in young adults informative. Methods In a comprehensive population-based survey of mental health in Finnish young adults (aged 21-35 years, n = 605, structured clinical interview (SCID-I complemented by medical record data from all lifetime hospital and outpatient treatments were used to diagnose SUDs. We estimated the prevalences of lifetime DSM-IV SUDs, and investigated their associations with correlates from four domains representing: (1 behavioral and affective factors, (2 parental factors, (3 early initiation of substance use, and (4 educational factors. Independence of the association of behavioral and affective factors with SUD was investigated. Results Lifetime prevalences of abuse or dependence of any substance, alcohol, and any illicit substance were 14.2%, 13.1%, and 4.4%, respectively. Correlates from all four domains were associated with SUD. The associations between behavioral and affective factors (attention or behavior problems at school, aggression, anxiousness and SUD were largely independent of other correlates, whereas only daily smoking and low education associated with SUD after adjustment for behavioral and affective factors. Conclusion Alcohol use disorders are common in Finnish young adults, whereas other SUDs are less common than in many other developed countries. Our cross-sectional analyses suggested that the association between behavioral and affective factors and SUD was only partly accounted for by other correlates, such as early initiation of substance use and parental

    2012-01-01

    Associations between two variables, for instance between brain and behavioral measurements, are often studied using correlations, and in particular Pearson correlation. However, Pearson correlation is not robust: outliers can introduce false correlations or mask existing ones. These problems are exacerbated in brain imaging by a widespread lack of control for multiple comparisons, and several issues with data interpretations. We illustrate these important problems associated with brain-behavior correlations, drawing examples from published articles. We make several propositions to alleviate these problems.

    assumptions permit the set to be completed. From the analysis, two distinct response groups were evident, with the salts of one group measurably more creep resistant than the other group. Interestingly, these groups correspond well with the indirectly determined creep closure of the SPR storage caverns, a correlation that probably should be expected. Certainly, the results suggest a simple laboratory determination of the creep characteristics of a salt material from a dome site can indicate the relative behavior of any potential cavern placed within that dome.

    Despite evidence that children of male war veterans with combat-related posttraumatic stress disorder (PTSD) are at particularly high risk for behavior problems, very little is currently known about suicidal behaviors in this population of youth. This study aimed to examine the prevalence and psychosocial correlates of suicide attempts among psychiatrically hospitalized adolescent offspring of Croatian male PTSD veterans. Participants were psychiatric inpatients, ages 12-18 years. Self-report questionnaires assessed demographics, suicide attempts, psychopathology, parenting style, and family functioning. The prevalence of suicide attempts was 61.5% (65.2% for girls and 58.0% for boys). Internalizing symptoms, family dysfunction, lower levels of maternal and paternal care, and paternal overcontrol were significantly associated with suicide attempts. Our findings suggest that suicide attempts are common among inpatient adolescent offspring of male PTSD veterans and that interventions targeting both adolescent psychopathology and family relationships are needed for adolescents who have attempted suicide.

    Recent statistics indicate that over one-third of college students are currently overweight or obese, however, the impact of weight in this population from academic and psychiatric perspectives is not fully understood. This study sought to examine the prevalence of overweight and obesity in college students and its association with stress, mental health disorders and academic achievement. A total of 1765 students completed the College Student Computer User Survey (CSCUS) online at a large Midwestern United States University. Responders were classified by weight as normal, overweight or obese based on body mass index. Data were stratified by sex, with cross-tabulation and t-tests, one-way analysis of variance, and logistic regression for analysis. A total of 492 (27.9%) students were overweight (20.2%; range 25.01-29.98) or obese (7.7%; range 30.04-71.26). Overweight and obesity were associated with significantly lower overall academic achievement, more depressive symptoms, and using diet pills for weight loss. Obese males had significantly higher rates of lifetime trichotillomania while overweight and obese females reported higher rates of panic disorder. Higher educational institutions should be aware of the significant burden associated with overweight and obesity in students, and of the differing demographic and clinical associations between overweight or obesity in men and women.

    Gambling has experienced world-wide growth. The current study is the first national survey into household gambling conducted in a developing country. The sample was a three-stage probabilistic one designed to cover individuals 14 years old or older, of both genders and from all regions of the national territory; 325 census sectors were visited, including rural areas. DSM-IV-based instruments were used to assess problem and pathological gambling; individuals were asked to estimate their monthly gambling expenditure. The lifetime prevalences were: pathological gambling 1.0%, and problem gambling 1.3%. Maximum gambling expenditure corresponded to 5.4% of the household income for social gamblers, 16.9% for problem gamblers and 20.0% for pathological gamblers. The male:female ratio among adults for pathological gambling was 3.2:1. The data suggest the existence of two subgroups of pathological gamblers, one younger (33.9±4.19) and severe (7 or more DSM-IV criteria), another older (47.8±6.01) and less severe (5-6 criteria). In a multinomial logistic regression, problematic gambling was associated with gender, age, education, employment, region of origin and living in metropolitan areas. The data suggest that feeling active and socially inserted protects against problematic gambling. Individuals who are young, male, unemployed or not currently pursuing further education may be at special risk for severe pathological gambling.

    Full Text Available Background: Polycystic ovarian syndrome (PCOS is the most frequent endocrinological disorder affecting young women of reproductive age having wide spread morbidity. Though, several factors have been identified attributing to its cause, yet it demands further investigations. Materials and Methods: A community-based cross-sectional study was carried out among 253 adolescent females (age: 10-19 years to elicit the associations between PCOS and the cesarean mode of delivery, eruption of wisdom tooth and other factors through a binary logistic regression analysis. Results: The mean age was 18.57 ΁ 0.19 (standard error of mean years. The prevalence of PCOS in Nellore district is 15.4% (95% confidence interval: 10.97-19.83. Higher risk of PCOS was associated with the cesarean mode of delivery (odds ratio [OR] = 4.91, P < 0.0001, eruption of at least 1 wisdom tooth (OR = 2.61, P = 0.025 and the presence of central obesity (OR = 2.57, P = 0.05. Discussion: An attempt has been taken to hypothesize causal association of associated factors with PCOS from the available literature, which in turn may pave the path for newer approaches for prevention and management.

    More data regarding prevalence and correlates of active travel to school are needed from different parts of the world. The purpose of this study was to examine prevalence and correlates of active travel to school among adolescents in Cyprus. A cross-sectional study was conducted among 1966 adolescents attending grade 6, grades 7-9, grades 10-12 and technical/vocational schools in Cyprus. Overall prevalence of active travel to school was 19.4%. Parental perceptions of safe route to school, other children walking to school from the child's neighborhood and school location (urban versus rural) were associated with active travel across different levels of education. Having enough time to walk to school in the moming was the most consistent correlate of active travel. Low prevalence estimates of active traveling to school among adolescents in Cyprus raise the need to promote this source of daily physical activity.

    This study assesses the ecological factors associated with microfilariae prevalence in wild populations of endangered flightless cormorants (Phalacrocorax harrisi) and Galápagos penguins (Spheniscus mendiculus). Prevalence values were tested for correlation with a large number of environmental variables, as modeled from weather station data and measured by satellite-borne sensors. Predictions were made based on the expected effects of climatic and landscape variables on sustained populations of arthropod vectors required for transmission of microfilariae. In general, findings were consistent with predictions in both cormorants and penguins; prevalence correlated positively with temperature, precipitation, and vegetation density, and negatively with measures of environmental variability. Resulting correlates were used to derive predictive distributions of prevalence values in cormorants throughout the archipelago. Evidence is presented implicating the mosquito Aedes taeniorhynchus as a likely vector. Knowledge of environmental variables that predict risk of disease transmission by arthropod vectors may be useful in control measures should novel pathogens be introduced to the ecosystem.

    Full Text Available Objective. Group fighting is portrayed as a piece of Americana among delinquent youth, but the behavior produces significant multifaceted negative consequences. The current study examines the heterogeneity and correlates of group fighting using national-level data. Method. Employing data from the National Survey on Drug Use and Health between 2002 and 2013 (n = 216,852, we examine links between group fighting and temperamental, parental, and academic factors as well as other externalizing behaviors (i.e., violence, crime, substance use. Results. The prevalence of group fighting in the United States is 14.8% with 11.33% reporting 1–2 group fights and 3.46% reporting 3+ group fights. A clear severity gradient in school functioning and academic performance, sensation seeking, parental disengagement, violence and delinquency, and substance use disorders is seen in the normative, episodic, and repeat offender groups. Conclusions. Youths who participate in 3+ group fights display the exceptionality and severity of other serious/chronic/habitual antisocial youth which suggests that group fighting should be considered a significant indicator of developing criminality.

    Children with autism spectrum disorder (ASD) may be at increased risk for overweight and obesity, but little information is known about correlates of overweight and obesity in this population. This study compared prevalence rates of parent-reported overweight and obesity and specific health behaviors (i.e., parent report of child sleep, family meal patterns, child screen time, and child physical activity) among children with ASD (N = more than 900 [weighted to represent 690,000; age 10-17]) compared with children without ASD using data from a nationally representative sample. Additionally, the relationship between specific health behaviors (i.e., child sleep, family meals, screen time, and physical activity) and weight status was examined in the ASD population. Data were from the National Survey of Children's Health 2011-2012. Results indicate that children with ASD were more likely to be obese but not more likely to be overweight than non-ASD youth. Children with ASD engaged in physical activity less than children without ASD, but no differences were found on sleep, most measures of screen time, and mealtimes. However, parent perceived poorer sleep was associated with increased weight status, and fewer family meals were associated with normal weight status among children with ASD.

    Suicide is a potentially preventable public health issue. It is therefore important to examine its immediate precursors, including suicidal ideation and attempts, to help in the development of future public health interventions. The present study reports the prevalence of suicidal ideation and attempts in the past 12 months in children and adolescents and identifies correlates of such behaviors in a large and diverse sample of middle and high school students. Data were drawn from a representative sample of Ottawa students (n=1922) aged 11-20 years (14.4±1.9 years) from three cycles (2009, 2011 and 2013) of the Ontario Student Drug Use and Health Survey (OSDUHS), a cross-sectional school-based appraisal of students in grades 7-12 across Ontario, Canada. Overall, 10.8% of students exhibited suicidal ideation and 3.0% reported suicide attempts in the past 12 months. The conditional probability of making an attempt was 25.5% among suicide ideators. Multivariable analyses indicated that being a girl and using alcohol and cannabis were positively associated with suicidal ideation, while tobacco was positively associated with suicide attempts. Being a victim of school bullying was significantly associated with reports of suicidal ideation and attempts, whereas school connectedness had protective effects against both suicidal ideation and attempts. These results indicate that suicidal ideation and attempts are related to other risky behaviors. Suicide-prevention efforts should be integrated within broader health-promoting initiatives.

    This study examined the lifetime prevalence and correlates of attempted suicide among transgender persons in Argentina. Data were derived from a nation-wide, cross-sectional survey conducted in 2013. We assessed individual, social, and structural correlates of reporting a history of attempting suicide using logistic regression. Among 482 participants, the median age was 30, 91% identified as transwomen, and 32% resided in the Buenos Aires metropolitan area. A lifetime suicide attempt was reported by 159 (33%), among whom the median age at first attempt was 17. In a multivariate model, internalized stigma was positively associated with a history of suicidal behavior, while participants with stable housing had reduced odds of prior suicide attempt(s). These findings suggest that reducing stigma and mitigating structural vulnerabilities (through, for example, the enactment and enforcement of laws that prohibit discrimination based on gender identity to ensure equitable access to housing) could be effective targets for intervention to reduce suicide attempts among transgender individuals in Argentina.

    Full Text Available Globally, client-perpetrated violence against female sex workers (FSWs has been associated with multiple health-related harms, including high-risk sexual behavior and increased exposure to HIV/STIs. This study examined correlates of client-perpetrated sexual, physical, and economic violence (e.g., robbery against FSWs in 13 cities throughout Mexico.FSWs (N = 1,089 who were enrolled in a brief, evidence-based, sexual risk reduction intervention for FSWs (Mujer Segura were interviewed about their work context, including experiences of violence perpetrated by clients, sexual risk and substance use practices, financial need, and social supports. Three broad categories of factors (sociodemographic, work context, behavioral and social characteristics of FSWs were examined as correlates of sexual, physical, and economic violence.The prevalence of different types of client-perpetrated violence against FSWs in the past 6 months was: sexual (11.7%, physical (11.8%, economic (16.9%, and any violence (22.6%. Greater financial need, self-identification as a street worker, and lower perceived emotional support were independently associated with all three types of violence. Alcohol use before or during sex with clients in the past month was associated with physical and sexual violence. Using drugs before or during sex with clients, injection drug use in the past month, and population size of city were associated with sexual violence only, and FSWs' alcohol use score (AUDIT-C was associated with economic violence only.Correlates of client-perpetrated violence encompassed sociodemographic, work context, and behavioral and social factors, suggesting that approaches to violence prevention for FSWs must be multi-dimensional. Prevention could involve teaching FSWs strategies for risk avoidance in the workplace (e.g., avoiding use of alcohol with clients, enhancement of FSWs' community-based supports, development of interventions that deliver an anti

    Full Text Available Background: Studies show that uptake of couples’ HIV counseling and testing (couples’ HCT can be affected by individual, relationship, and socioeconomic factors. However, while couples’ HCT uptake can also be affected by background HIV prevalence and awareness of the existence of couples’ HCT services, this is yet to be documented. We explored the correlates of previous couples’ HCT uptake among married individuals in a rural Ugandan district with differing HIV prevalence levels. Design: This was a cross-sectional study conducted among 2,135 married individuals resident in the three HIV prevalence strata (low HIV prevalence: 9.7–11.2%; middle HIV prevalence: 11.4–16.4%; and high HIV prevalence: 20.5–43% in Rakai district, southwestern Uganda, between November 2013 and February 2014. Data were collected on sociodemographic and behavioral characteristics, including previous receipt of couples’ HCT. HIV testing data were obtained from the Rakai Community Cohort Study. We conducted multivariable logistic regression analysis to identify correlates that are independently associated with previous receipt of couples’ HCT. Data analysis was conducted using STATA (statistical software, version 11.2. Results: Of the 2,135 married individuals enrolled, the majority (n=1,783, 83.5% had been married for five or more years while (n=1,460, 66% were in the first-order of marriage. Ever receipt of HCT was almost universal (n=2,020, 95%; of those ever tested, (n=846, 41.9% reported that they had ever received couples’ HCT. There was no significant difference in previous receipt of couples’ HCT between low (n=309, 43.9%, middle (n=295, 41.7%, and high (n=242, 39.7% HIV prevalence settings (p=0.61.

    Complementary correlations can reveal the genuine quantum correlations present in a composite quantum system. Here, we explore an effective method to identify the entangled Bell diagonal states by means of Pearson correlation, one of the complementary correlations. Then, we extend this method to expose the dynamic behavior of complementary correlations under various kinds of decoherence channels. The sudden death and revival of entanglement can be explained by the idea of Pearson correlation. The threshold that is used to identify entanglement is proposed. Furthermore, we put forward a new method to expound the underlying physical mechanisms for which classical and quantum correlations suffer a sudden change in the decoherence process.

We evaluated the prevalence of symptoms of ADHD and the correlates thereof in Korean college students. Methods: A total of 2,172 college students, stratified to reflect geographical differences, were asked to complete self-report questionnaires on ADHD symptoms, depression, and related factors. Results: ADHD symptoms were found in 7.6% of college students. Univariate analysis revealed that younger students had higher rates of ADHD symptoms than did older students. We found significant associations between ADHD symptoms and problematic alcohol use, depression, and lifetime suicidal behavior. Multivariate analysis revealed that ADHD symptoms in adults were significantly associated with depression (odds ratio [OR] =4.69; 95% confidence interval [CI] 3.23–6.80; P<0.001 and overweight or obesity (OR =1.50; 95% CI 1.02–2.22; P=0.040, after controlling for sex and age.

    Full Text Available Despite their perceived vulnerability to HIV, East African street youth have been neglected in HIV prevention research. We examined HIV seroprevalence and correlates of HIV infection in a sample of male street youth in Kisumu, Kenya.We enrolled a street-recruited sample of 13-21 year old street youth. Participants completed a survey followed by voluntary HIV counseling and testing. Survey items included demographics, homelessness history, survival activities, sexual behavior and substance use. We examined the relationship between predictor variables, markers of coercion and marginalization and HIV.The sample included 296 males. Survival activities included garbage picking (55%, helping market vendors (55%, begging (17%, and working as porters (46% or domestic workers (4%. Forty-nine percent of participants reported at least weekly use of alcohol and 32% marijuana. Forty-six percent of participants reported lifetime inhalation of glue and 8% fuel. Seventy-nine percent of participants reported lifetime vaginal sex, 6% reported lifetime insertive anal sex and 8% reported lifetime receptive anal sex. Twelve (4.1%; 95% CI: 2.3-7.0 participants tested positive for HIV. Of those, all had been on the street for at least one year and all had engaged in vaginal sex. Occupations placing youth at particular risk of coercion by adults, including helping market vendors (prevalence ratio (PR = 8.8; 95% CI: 1.2-67.5 and working as domestic workers (PR = 4.6; 95% CI: 1.1-19.0, were associated with HIV infection. Both insertive anal sex (PR = 10.2; 95% CI: 3.6-29.4 and receptive anal sex (PR = 3.9; 95% CI: 1.1-13.4 were associated with HIV infection. Drug use, begging, and garbage picking were not associated with HIV infection.Although HIV prevalence in our sample of street youth is comparable to that of similarly-aged male youth in Nyanza Province, our findings highlight behavioral factors associated with HIV infection that offer opportunities for targeted

All participants answered the German SHI, the short form of the Barratt Impulsiveness Scale (BIS-15, the ultra-brief Patient Health Questionnaire for Depression and Anxiety (PHQ-4, and provided sociodemographic information. The one-factorial structure of the SHI was replicated using a confirmatory factor analysis. Internal consistency coefficients were sufficient and in line with previous studies. Almost half of the sample (49% acknowledged at least one self-harming behavior over the life-span, most frequently indirect forms of self-harm. The rate of participants who engaged in at least one SHI behavior was higher among men than women (51.6% vs. 46.9%, respectively, χ2 = 5.38, p = 0.020. Higher SHI scores were related to younger age, male gender, living alone, more symptoms of anxiety and depression (PHQ-4, higher impulsivity scores (BIS-15, and suffering from obesity grade 2.

    Full Text Available Financial debt in young people has increased in recent years. Because debt may have severe consequences, and it may enhance criminal behavior, insight into the prevalence and determinants of debt and its association with crime is important. We conducted a systematic review and meta-analysis of 36 manuscripts to examine the prevalence of financial debt (k = 23, correlates and risk factors of debt (k = 16, and associations between debt and criminal behavior in adolescents and young adults (k = 8. Findings revealed that the prevalence of debt is substantial among young people; on average, 49% reported to have at least some debt, 22% had financial problems. Older participants and ethnic minorities were found to have higher levels of debt than younger and indigenous counterparts. Females had more financial problems and higher student loans. Low self-esteem, a pro-debt attitude (of young people and their parents, lack of perceived control towards financial management, poor social functioning, financial stress and external locus of control were found to have the strongest associations with debt. Studies reported strong associations between debt and crime. Particularly, strong associations were found between serious and persistent crime in young people and later (young adult debt or financial problems.

    Although vitamin K deficiency has been implicated in adult inflammatory bowel disease (IBD), its prevalence in pediatric IBD remains unknown. We carried out a cross-sectional study in 63 children with Crohn's disease (CD) and 48 with ulcerative colitis (UC) to assess the prevalence of vitamin K deficiency and to search for potential correlation between vitamin K status and pediatric IBD activity. Vitamin K status was assessed using protein induced by vitamin K absence-II (PIVKA-II; ELISA). Prevalence of vitamin K deficiency was 54.0% in CD and 43.7% in UC. Vitamin K deficiency was more common in patients with higher CD activity, in CD patients with higher mass Z-scores, and less common among children with CD treated with infliximab. Relation of vitamin K deficiency to pediatric IBD clinical course and treatment demand further research.

    OBJECTIVES: We investigated the prevalence of obesity and the metabolic correlates of different levels of body mass index (BMI) and waist circumference among the Inuit in 3 countries. METHODS: Data from 4 surveys of Inuit in Canada, Greenland, and Alaska conducted during 1990-2001 were pooled......, with a total sample size of 2545 participants. These data were compared with data from a Canadian population of predominantly European origin. RESULTS: Using the World Health Organization criteria for overweight and obesity, we found that the crude prevalence of overweight among Inuit men and women was 36.......6% and 32.5%, respectively, and obesity was 15.8% and 25.5%, respectively. Inuit prevalences were similar to those of the highly developed countries of Europe and North America. As levels of obesity increased, as measured by BMI or waist circumference, the mean values of various metabolic indicators...

    Full Text Available To determine the prevalence and correlates of alcohol dependence disorders in persons receiving treatment for HIV and Tuberculosis (TB at 16 Primary Health Care centres (PHC across Zambia.649 adult patients receiving treatment for HIV and/or TB at PHCs in Zambia (363 males, 286 females were recruited between 1st December 2009 and 31st January 2010. Data on socio-demographic variables, clinical disease features (TB and HIV, and psychopathological status were collected. The Mini International Neuropsychiatric Interview (MINI was used to diagnose alcohol dependence disorder. Correlates of alcohol dependence were analyzed for men only, due to low prevalence in women. Univariable and multivariable logistic regression models were used to estimate odds ratios (OR and 95% confidence intervals (CI, using general estimating equations to allow for within-PHC clustering.The prevalence of alcohol dependence was 27.2% (95%CI: 17.7-39.5% for men and 3.9% (95%CI: 1.4-0.1% for women. Factors associated with alcohol dependence disorder in men included being single, divorced or widowed compared with married (adjusted OR = 1.47, 95%CI: 1.00-2.14 and being unemployed (adjusted OR=1.30, 95%CI: 1.01-1.67. The highest prevalence of alcohol dependence was among HIV-test unknown TB patients (34.7%, and lowest was among HIV positive patients on treatment but without TB (14.1%, although the difference was not statistically significant (p=0.38.Male TB/HIV patients in this population have high prevalence of alcohol dependence disorder, and prevalence differs by HIV/TB status. Further work is needed to explore interventions to reduce harmful drinking in this population.

    BACKGROUND: Equestrian sport carries with it an implicit risk of injury. Despite the frequency of injuries in equestrian sports, there is no published study on injuries of equestrian athletes in Malaysia. OBJECTIVE: The objective of this study was to determine the prevalence of injuries and its correlates among horseback riders. SUBJECTS AND METHODS: A web-based standardized questionnaire was used to collect data for this cross-sectional survey. Horseback riders aged 18 years and above were included in the study. Out of 169 participants, 93 were females and 76 were males. The correlation of injuries to gender, age, level of experience, exercise habits, use of safety measures, and type of equestrian sport were determined. Chi-square test was performed to test for statistical significance. RESULTS: The prevalence was high with 85.8% of the participants reporting symptoms and characteristics of injuries in the past 12 months. The most frequently perceived symptoms reported were in the upper extremities (43.4%) followed by lower extremities (40.7%), head injury (8.3%) and injuries of upper and lower back (3.4%). There was a higher prevalence of injury among female participants (55.03%) than males (42.60%). A significant correlation was found between gender and prevalence of injuries. About 70% of the riders sustained soft tissue injuries. Fifty-five percent of the injured were involved in recreational riding. The most common mechanism of injury was a fall from a horse. Sixty percent of the injured riders did not seek medical attention after being injured, and physiotherapy consultation was even lower with 10.3%. CONCLUSIONS: The high prevalence of injuries and low rate of medical consultation emphasize the need for education programs on safety in Malaysia. Sessions should be held to improve coaching for riders and instructors, and their knowledge of the nature of the horse, mechanisms of injuries, horse handling, and riding skills to help them host safe equestrian

    Full Text Available Background. Complementary and alternative medicine (CAM therapies are being widely used by hypertensive patients worldwide. However, evidences regarding CAM use by hypertensive patients in Ethiopia are limited. This study aimed at assessing prevalence and correlates of CAM use among hypertensive patients attending ambulatory clinic at Gondar University Referral Hospital (GURH, Ethiopia. Methods. A cross-sectional study was employed on 423 patients visiting GURH. Descriptive statistics and bivariate and multivariate logistic regression tools were used to analyze/come up with the prevalence and correlates of CAM use. Results. The prevalence of CAM use in our study was found to be 67.8% and herbal based medicine was the most commonly utilized CAM therapies. Majority of CAM users (70.2% did not disclose CAM use for their physician. However, nearly half of CAM users (48.4% were satisfied with the result of CAM use. Conclusions. The higher prevalence of CAM use among hypertensive patients coupled with a very low disclosure rate to their health care providers can have a marked potential to cause ineffective hypertensive management and adverse effects due to CAM use. Health care providers should be open to discussing the use of CAM with their patients as it will lead to better health outcome.

    Full Text Available This study examined the prevalence and correlates of smoking initiation among adolescents. We have used data from adolescents (n=5,392 ages 10-18 who participated in the 2003 Tobacco Survey, a representative sample of adolescents in Northwest Ohio. A selfreport of cigarette smoking was obtained using a questionnaire administered in classrooms. Data were analyzed using weighted chi-square and multiple logistic regressions in SAS that accounted for the survey design. The prevalence rates for adolescents that ever tried smoking were 7.4% in elementary (grades 4-5; 17.7% in middle (grades 6-8, and 41.4% in high (grades 9-12 schools, respectively. The highest prevalence rate was among Hispanics. Having a close friend that smoked and a smoker at home correlated significantly with both initiation of smoking and smoking at an earlier age. Smoking was correlated with low academic achievement among adolescents in all grades. Students who reported smoking by parents or siblings were significantly more likely to start smoking at an earlier age, compared to other students living in a non-smoking home environment. Smoking prevention program should include components focused on adolescents’ home environment and should start as early as the 4th grade.

    Much is known about the prevalence and correlates of dating violence, especially the perpetration of physical dating violence, among older adolescents. However, relatively little is known about the prevalence and correlates of the perpetration of cyber dating abuse, particularly among early adolescents. In this study, using a predominantly ethnic-minority sample of sixth graders who reported ever having had a boyfriend/girlfriend (n = 424, 44.2 % female), almost 15 % reported perpetrating cyber dating abuse at least once during their lifetime. Furthermore, using a cross-sectional design, across multiple levels of the socio-ecological model, the individual-level factors of (a) norms for violence for boys against girls, (b) having a current boyfriend/girlfriend, and (c) participation in bullying perpetration were correlates of the perpetration of cyber dating abuse. Collectively, the findings suggest that dating violence interventions targeting these particular correlates in early adolescents are warranted. Future studies are needed to establish causation and to further investigate the relative importance of correlates of the perpetration of cyber dating abuse among early adolescents that have been reported among older adolescents.

    A large sample of 2-12 year old children (N = 2311) was studied to determine the relationship between three sexually intrusive behavior items (SIBs) measured by the Child Sexual Behavior Inventory (CSBI) and a range of developmental, ecological, and behavioral correlates. The variables studied included age, gender, race, family income, single parent status, maternal education, family sexual behaviors, physical abuse, sexual abuse, domestic violence, social competence of the child, and three scales from the CBCL (Internalizing, Externalizing, and PTSD). Sexual abuse was not the primary predictor of SIB, but a model incorporating family adversity, modeling of coercive behavior, child behavior, and modeling of sexuality predicted a significant amount of variance.

    This study tested the relationship between family dynamics and self-injury. A total of 189 participants responded to a web-based survey collecting information related to previous self-injury behaviors and family dynamics. Participants were over 18 years old who had used self-injury (intentionally harming themselves physically to relieve painful emotions without suicidal intent), but who had not used self-injury for over a year. Results indicated that healthy family dynamics were negatively correlated and associated with higher scores of self-injury behaviors. This study offers some evidence that family dynamics influence self-injury behaviors. The implications for family therapy are discussed.

    To investigate the prevalence, correlates, attitude and treatment seeking behavior of erectile dysfunction(ED) in type2 diabetes mellitus (T2DM) patients in the primary care setting, a multi‑center cross‑sectional survey using a structured anonymous self‑administered questionnaire was performed in 10 general outpatient clinics. Of the 603 subjects(91% response rate), the prevalence of ED men, as deifned by the International Index of Erectile Function, was 79.1%. Most subjects had mild ED(28.9%), followed by mild‑to‑moderate ED(27.9%), then moderate ED(13.4%) and severe ED(9%). Nearly 55% of those with ED did not consider themselves as having ED. Less than 10% of them had ever sought medical treatment, although 76.1% of them wished to receive management from doctor(s) should they be diagnosed with ED. They considered the most important management from doctors to be clinical assessment(41.7%), followed by management of potential underlying cause(37.8%), referral to specialist(27.5%), education(23.9%), prescription of phosphodiesterase type5 inhibitors(16.9%) and referral to counseling service(6.7%). The prevalence of ED was strongly associated with subjects who thought they had ED(odds ratio(OR)= 90.49(20.00–409.48, P<0.001)) and were from the older age group(OR=1.043(1.011–1.076,P=0.008)). In conclusion, ED is highly prevalent among T2DM men. The majority of them wanted management from doctors should they have ED, but only a minority would actually voice out the request. Screening of ED among T2DM men using structural questionnaire allowed the diagnosis of more than half of the ED cases, which otherwise would have gone undiagnosed.

    Full Text Available Backround/Aim. Adolescence is the period of greatest risk of starting to use substances: cigarette smoking, alcohol and illicit drugs. In the first decade of this millennium substance use among adolescents has increased. The aim of this study was to explore the prevalence of substances use among adolescents and its correlation with social and demographic factors. Methods. The study was conducted among adolescents in Novi Sad during 2010-2011 and included 594 conveniently selected adolescents (275 male and 319 female, aged 15-19 years. A special questionnaire was used and statistical analysis performed in SPSS17. The correlation between parameters was evaluated by the Pearson correlation method and frequency differences were analysed using χ2 test and starting level was p < 0.05. Results. The prevalence of substance use was statistically higher in males. Cigarettes were smoked daily by 21.45% males and 15.67% females (p < 0.01, alcohol was consumed by 81.6% males and 69.11% females (p < 0.001 and illicit drugs were used by 13.65% males and 8.30% females (p < 0.05. There was a positive correlation between smoking cigarettes and alcohol consumption, but negative between smoking cigarettes and the use of illicit drugs (p < 0.01. The prevalence of substance use was statistically higher among adolescents with poor achievement in school (p < 0.01, who lived in a broken home (illicit drugs p < 0.01 and who had more pocket money (cigarette smoking p < 0.01, and alcohol consumption p < 0.5. Conclusion. Stable family, lower amount of pocket money weekly and good school performance are protective factors in prevention of substances use among adolescents.

    Full Text Available Abstract Background Little is known about the HIV/AIDS epidemic in the Indian Ocean region, including Mauritius. National records suggest a prevalence of HIV in Mauritius of Methods We identified 1200 participants using two-stage cluster sampling. Demographic, social, sexual, and knowledge of HIV/AIDS data were obtained in face-to-face interviews using a structured questionnaire administered by trained interviewers. The prevalence of sexual behaviors was described in relation to gender, and the correlates of ever having had sex and nonuse of condom at last sex were analyzed using logistic regression. Results In the target population, 30.9% of males and 9.7% of females reported a history of sexual intercourse. Of the currently sexually active participants, 50.6% of men and 71.2% of women did not use condoms at their last sexual encounter. Logistic regression revealed that work experience and marijuana use were significantly associated with men's sexual experience, whereas being out of school and drinking experience were significantly associated with women's sexual experience. For both men and women, being Christian and visiting nightclubs were associated with having ever had sexual intercourse (P Conclusion Young people in Mauritius are at risk of a future HIV epidemic because behaviors predisposing to HIV infection are prevalent among sexually experienced youth. A focused prevention program targeting young people should be reinforced as part of the National AIDS Control Program, taking into account the predictors of sexual behaviors identified here.

    Full Text Available Abstract Background Childhood obesity is becoming an equally challenging, yet under-recognized, problem in developing countries including Pakistan. Children and adolescents are worst affected with an estimated 10% of the world's school-going children being overweight and one quarter of these being obese. The study aimed to assess prevalence and socioeconomic correlates of overweight and obesity, and trend in prevalence statistics, among Pakistani primary school children. Methods A population-based cross-sectional study was conducted with a representative multistage cluster sample of 1860 children aged 5-12 years in Lahore, Pakistan. Overweight (> + 1SD and obesity (> + 2SD were defined using the World Health Organization child growth reference 2007. Chi-square test was used as the test of trend. Linear regression was used to examine the predictive power of independent variables in relation to BMI. Logistic regression was used to quantify the independent predictors for overweight and adjusted odds ratios (aOR with 95% confidence intervals (CI were obtained. All regression analyses were controlled for age and gender and statistical significance was considered at P Results Seventeen percent (95% CI 15.4-18.8 children were overweight and 7.5% (95% CI 6.5-8.7 were obese. Higher prevalence of obesity was observed among boys than girls (P = 0.028, however, there was no gender disparity in overweight prevalence. Prevalence of overweight showed a significantly increasing trend with grade (P Conclusion Alarmingly rapid rise in overweight and obesity among Pakistani primary school children was observed, especially among the affluent urban population. The findings support the urgent need for National preventive strategy for childhood obesity and targeted interventions tailored to local circumstances with meaningful involvement of communities.

    Despite the increasing rates of obesity in the U.S. and corresponding rise in weight-related concerns among men and women in all ethnic groups, most research in the U.S. has been conducted using white female samples. This study explored the prevalence and correlates of chronic dieting (high levels of dietary restraint) among a U.S. communitybased sample of Hispanic, Asian, Black, and White women and men (N=1257). Chronic dieting was more common among women than men, and less common among Asians than other ethnic groups. Across the total sample, dietary restraint was positively correlated with weight history, disordered eating attitudes, distorted body experiences, and depression, and was negatively correlated with self-esteem. Female chronic dieters showed the highest degree of disturbance; compared with female non-dieters (and male chronic dieters), they reported lower self-esteem, higher depression, and more disordered eating attitudes. As hypothesized, they also exhibited a higher degree of acculturation to Anglo-American society. Male chronic dieters had more disordered eating attitudes and experienced greater body distortion than male non-dieters. Interestingly, these results were not moderated by ethnicity. Although the prevalence of chronic dieting differs among ethnic groups living in the U.S., the psychological characteristics related to eating and weight appear similar for individuals who diet, irrespective of ethnicity.

    This study used the data from a representative sample to estimate the prevalence of child bullying victimization in Xi'an, China. Data on social demographic information and the experiences of different types of bullying victimization were collected from a randomly selected sample with 3,175 middle school students aged 15-17 years by self-administrated questionnaires. t Test, χ2 test, and multiple logistic regression analyses were used to test group differences and examine the correlates of bullying victimization. Results show that 54.9% and 44.6% of Chinese children have been bullied in a lifetime and in the preceding year, respectively. Correlates for direct and relational bullying victimization includes male participants, father's lower education level, father's unemployment, having one or more siblings, smoking, depression, borderline personality trait, posttraumatic stress disorder, and from rural schools. Overall, the prevalence of child bullying victimization in China is substantial. The multiple correlates suggest prevention and intervention of bullying victimization in a holistic and comprehensive way.

    Coca-Cola (Coke) and Pepsi are nearly identical in chemical composition, yet humans routinely display strong subjective preferences for one or the other. This simple observation raises the important question of how cultural messages combine with content to shape our perceptions; even to the point of modifying behavioral preferences for a primary reward like a sugared drink. We delivered Coke and Pepsi to human subjects in behavioral taste tests and also in passive experiments carried out during functional magnetic resonance imaging (fMRI). Two conditions were examined: (1) anonymous delivery of Coke and Pepsi and (2) brand-cued delivery of Coke and Pepsi. For the anonymous task, we report a consistent neural response in the ventromedial prefrontal cortex that correlated with subjects' behavioral preferences for these beverages. In the brand-cued experiment, brand knowledge for one of the drinks had a dramatic influence on expressed behavioral preferences and on the measured brain responses.

    Objective:To determine the prevalence of HIV infection among homeless men and women and the related risk behaviors in Tehran, Iran. Methods: In 2007-2008, Tehran municipality stacked up 10 657 homeless men and women for assessment of HIV and began collaboration with Iranian Research Center for HIV/AIDS (IRCHA) departments to conduct HIV infection prevalence surveys in homeless populations. The results were analyzed for associations with demographic information, family support, status of drug abuse and relation with family and friends. Results:Overall HIV prevalence was 1.7%(95%confidence interval 1.4-1.9). Factors independently associated with HIV infection included history of using drugs [AOR 8.15 (4.86-13.67)], older age [AOR 1.80 (1.08-2.99) for 40- 55 yr], occupation [AOR 1.64 (1.19-2.24) for unemployed], and no relation with family [AOR 1.82 (1.30-2.54)]. Conclusions: This study supports the idea that injection drug use is contributing to the increased spread of HIV among Iranian homeless. Harm reduction programs should be expanded, particularly among homeless injection drug users.

    Full Text Available Abstract Background Bicycle use entails high safety and health risks especially for adolescents. Most safety education programs aimed at adolescents focus on accident statistics and risk perceptions. This paper proposes the investigation of the social-cognitive correlates of risky cycling behaviors of adolescents prior to developing safety education programs. Method Secondary school students aged 13 to 18 years (n = 1446 filled out questionnaires regarding bicycle behavior, risky intentions, accident experience, and social-cognitive determinants as suggested by the theory of planned behavior. Results Regression analysis revealed that the proximal variables (i.e., self-efficacy, attitudes towards drunk driving, personal norm regarding safekeeping of self and others, and compared risk were able to predict 17% of the variance of risky behavior and 23% of the variance of risky intentions. The full model explained respectively 29% and 37% of the variance in risky behavior and risky intentions. Adolescents with positive attitudes towards risky behavior and low sense of responsibility report risky behavior, even when having been (close to an accident. Conclusions Adolescents realize whether they are risk takers or not. This implies that the focus of education programs should not be on risk perceptions, but on decreasing positive attitudes towards alcohol in traffic and increasing sense of responsibility instead. Cognitions regarding near accidents should be studied, the role of safe cycling self-efficacy is unclear.

    This cross-sectional study evaluated the prevalence of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), axis I mental disorders among Spanish female students and investigated their psychiatric comorbidity and correlates. 1054 female students with a mean age of 22.2 years were randomly selected, with stratification by academic seniority and the type of academic discipline. The cases of mental disorder were identified by clinically trained interviewers with the aid of the Structured Clinical Interview for DSM-IV Axis I Disorders-Clinician Version. The lifetime prevalence of the targeted psychiatric disorders was 50.8%, and its point prevalence was 37.3%. The commonest disorders were nicotine dependence, depression, and generalized anxiety disorder. Nearly 37% of subjects with a psychiatric disorder had two or more diagnoses. Mental illness was associated with family income, financial independence, type of academic discipline, violence from men, social support, and self-esteem. Psychiatric disorders are common among female university students. Serious attention should be paid to preventive and therapeutic programs in this group.

    Objective: To study the prevalence of chondromalacia patella among college students and the correlation with sports injury. Methods: 354 students from gymnastic department and 429 from nongymnastic department with knee joint pain were selected. 184 students from gymnastic department and 342 from nongymnastic department were checked randomly by a surgeon. 77 patients (37 males, 40 females) from gymnastic department and 119 patients (62 males, 57 females) from nongymnastic department were diagnosed as chondromalacia patellae. The amount of exercise and the occurrence of sports injury were investigated in each student. All data were analyzed with SPSS 10.0 statistical software. Results: The prevalence of chondromalacia patella was 20.1% in female students and 11.6% in male students from gymnastic department, and 5.61% in female students and 4.92% in male students from nongymnastic department. The amount of exercise and the occurrence of sports injury to the knee joint in students from gymnastic department were greater than those from nongymnastic department. Conclusions: In both female and male students, the prevalence of chondromalacia patella is higher in gymnastic department than nongymnastic department. Sports injury is an important cause of chondromalacia patella.

    Full Text Available Background: With a rising trend of Non-Communicable Diseases (NCDs in the present world, overweight and obesity has gained importance as it is not only a disease in itself but also risk factor for majority of other NCDs. A dramatic increase in overweight and obesity among children and adolescent has raised the concern of various public health physicians especially in developing country like India. Aims & Objective: To study the prevalence of overweight and obesity & its correlates among school going adolescents of Haldwani block. Material & Methods: School based cross sectional study was done among the adolescents of 8th to 12th standard. To calculate the maximum sample size prevalence of obesity was assumed to be 50%, taking absolute error of 5%, design effect of 2 and 10% non-response rate the sample was calculated to be 880, rounded off to 900. Samples were collected from 30 clusters/schools using simple random sampling. Data was collected using a pre-designed, semi-structured and pre-tested questionnaire and analyzed by using SPSS version 22. Results: Prevalence of overweight and obesity was 13% (CI = 10.8 - 15.2%. Overweight and obesity was found to be significantly associated with urban area, private school, Socio-economic class I, non-vegetarian diet, physical inactivity and playing videogames, working on laptops and computer on univariate analysis. On applying binary logistic regression factors like private schools, socioeconomic class I, non-vegetarian diet and physical inactivity were again found to be significantly associated with overweight and obesity. Conclusion: Prevalence of obesity was found to be more in adolescents having modifiable risk factors.

    Our aim was to assess the prevalence and demographic correlates of overweight and obesity among children in Albania, a transitional country in Southeastern Europe. A nationwide survey was conducted in Albania in 2013 including a representative sample of 5,810 schoolchildren aged 7.0-9.9 years (51.5 % boys aged 8.5 ± 0.6 years and 49.5 % girls aged 8.4 ± 0.6 years; overall response: 97 %). All children were measured height and weight, based on which the body mass index (BMI) was calculated. The criteria of the World Health Organization (WHO) and the International Obesity Task Force (IOTF) were used to describe the distribution of BMI among children. Overall, mean value of BMI was 16.4 ± 2.4 (16.7 ± 2.5 in boys vs. 16.2 ± 2.4 in girls, P < 0.001). As per WHO criteria, 9.8 % of the boys were obese versus 5.5 % of the girls (P < 0.001). The prevalence of both overweight and obesity were remarkably higher among urban children compared with their rural counterparts (17.9 vs. 10.5 and 11.9 vs. 4.0 %, respectively, P < 0.001). As per IOTF criteria, 3.8 % of the boys were obese compared with 2.8 % of the girls (P < 0.001). The prevalence of overweight and obesity were similarly higher among urban children than in rural children (15.6 vs. 7.3 and 5.5 vs. 1.4 %, respectively, P < 0.001). Our findings indicate that Albania is in the middle of nutritional transition with a high prevalence of overweight and obesity among children aged 7.0-9.9 years. This is particularly evident in urban areas of the country. Conversely, our data do not indicate a double burden of malnutrition among children in Albania.

    Full Text Available OBJECTIVES: The present study aimed to investigate the prevalence and correlates of dental caries in elderly population in northeast China. METHODS: A community-based, cross-sectional study among 2376 elderly subjects (age: 65-74 years from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT and decayed-filled teeth (DFT indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197. T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs and corresponding confidence intervals (CIs. RESULTS: 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40, and the prevalence was higher in urban areas (P<0.01. Missing teeth accounted for 80.72% of DMFT, and filled teeth due to caries accounted for 2.08% with a rate higher in urban areas (P<0.01. Logistic regression analysis indicated significant association among elderly population in urban areas (OR 1.713; 95% CI 1.337-2.195, smoking (OR 1.779; 95% CI 1.384-2.288, and individuals without dental insurance (OR 2.050; 95% CI 1.120-3.754 with dental caries. CONCLUSIONS: The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries.

    Full Text Available There is scanty information on correlates for psychosocial distress in Zambia. Secondary analysis was conducted using data collected in 2004 in Zambia during the global school-based health survey to determine the prevalence and correlates for psychosocial distress. Logistic regression analyses were used to estimate magnitudes of associations between exposure factors and the outcome, while the Yates’ corrected Chi-squared test was used to compare proportions at the 5% significance level. A total of 2257 students participated in the survey of which 54.2% were males. Males were generally older than females (p<0.001. Significantly more females than males were bullied (p=0.036, involved in a fight (p=0.019 and consumed alcohol (p=0.012. Psychosocial distress was detected in 15.7% of the participants (14.4% of males and 16.8% of females. Age less than 14 years, male gender, parental support for males and having close friends were protective factors against psychosocial distress. Risk factors for psychosocial distress were: being bullied, involvement in a fight, alcohol consumption, being physically active and parental support. . Age less than 14 years, male gender, parental support for males, having close friends, being bullied, involvement in a fight, alcohol consumption, being physically active and parental support were significantly associated with psychosocial distress. The prevalence of psychosocial distress among adolescents in Zambia appears to be common. There is a need to validate the psychosocial distress indicators that were used in the current study.

    Attention is a means of flexibly selecting and enhancing a subset of sensory input based on the current behavioral goals. Numerous signatures of attention have been identified throughout the brain, and now experimenters are seeking to determine which of these signatures are causally related to the behavioral benefits of attention, and the source of these modulations within the brain. Here, we review the neural signatures of attention throughout the brain, their theoretical benefits for visual processing, and their experimental correlations with behavioral performance. We discuss the importance of measuring cue benefits as a way to distinguish between impairments on an attention task, which may instead be visual or motor impairments, and true attentional deficits. We examine evidence for various areas proposed as sources of attentional modulation within the brain, with a focus on the prefrontal cortex. Lastly, we look at studies that aim to link sources of attention to its neuronal signatures elsewhere in the brain.

    Full Text Available Abstract Background Child growth is internationally recognized as an important indicator of nutritional status and health in populations. Child under-nutrition is estimated to be the largest contributor to global burden of disease, and it clusters in South Asia but literature on under-nutrition among school-aged children is difficult to find in this region. The study aimed to assess the prevalence and socio-demographic correlates of stunting and thinness among Pakistani primary school children. Methods A population-based cross-sectional study was conducted with a representative multistage cluster sample of 1860 children aged 5-12 years in Lahore, Pakistan. Stunting ( Results Eight percent (95% CI 6.9-9.4 children were stunted and 10% (95% CI 8.7-11.5 children were thin. Stunting and thinness were not significantly associated with gender. Prevalence of stunting significantly increased with age among both boys and girls (both P 8 years, rural area and urban area with low SES, low-income neighborhoods, lower parental education, more siblings, crowded housing and smoking in living place (all P 10 years (P = 0.003, more siblings (P = 0.016 and crowded housing (P = 0.006.

    Full Text Available OBJECTIVE: To estimate the prevalence and identify correlates of smokeless tobacco consumption among married rural women with a history of at least one pregnancy in Madaripur, Bangladesh. MATERIALS AND METHODS: We conducted a cross-sectional survey using an interviewer administered, pre-tested, semi-structured questionnaire. All women living in the study area, aged 18 years and above with at least one pregnancy in their lifetime, who were on the electoral roll and agreed to participate were included in the study. Information on socio-demographic characteristics and smokeless tobacco consumption was collected. Smokeless tobacco consumption was categorized as 'Current', 'Ever but not current' and 'Never'. Associations between smokeless tobacco consumption and the explanatory variables were estimated using simple and multiple binary logistic regression. RESULTS: 8074 women participated (response rate 99.9%. The prevalence of 'Current consumption', 'Ever consumption but not current', and 'Never consumption' was 25%, 44% and 31%, respectively. The mean age at first use was 31.5 years. 87% of current consumers reported using either Shadapata or Hakimpuree Jarda. Current consumption was associated with age, level of education, religion, occupation, being an income earner, marital status, and age at first use of smokeless tobacco. After adjustment for demographic variables, current consumption was associated with being over 25 years of age, a lower level of education, being an income earner, being Muslim, and being divorced, separated or widowed. CONCLUSION: The prevalence of smokeless tobacco consumption is high among rural women in Bangladesh and the age of onset is considerably older than that for smoking. Smokeless tobacco consumption is likely to be producing a considerable burden of non-communicable disease in Bangladesh. Smokeless tobacco control strategies should be implemented.

    OBJECTIVE Data on latent autoimmune diabetes in adults (LADA) from population-based studies are sparse. We sought to investigate the prevalence and correlates of LADA. RESEARCH DESIGN AND METHODS A total of 8,109 participants, who were aged ≥15 years and living in Tianjin, China, were assessed to identify individuals with type 2 diabetes (American Diabetes Association Criteria, 1997) and further to detect patients with LADA. LADA was ascertained by 1) the presence of type 2 diabetes and age ≥35 years, 2) the lack of a requirement for insulin at least 6 months after the diagnosis of type 2 diabetes, and 3) serum GAD antibody positivity. Data were analyzed using multinomial logistic regression with adjustment for potential confounders. RESULTS Of all participants, 498 (6.1%) were patients with type 2 diabetes. Of them, 46 (9.2%) were found to have LADA. The prevalence of LADA was 0.6% (46 of 8,109), and tended to increase with age up to 50–59 years in all participants. The odds ratios (95% CI) of LADA related to hypertension, family history of diabetes, waist-to-hip ratio ≥0.85, and major stressful events were 1.93 (1.02–3.65), 17.59 (9.08–34.06), 5.37 (2.31–12.49), and 4.09 (1.75–9.52), respectively. CONCLUSIONS The prevalence of LADA is ∼9% in patients with type 2 diabetes. Hypertension, family history of diabetes, central obesity, and major stressful events may be associated with the occurrence of LADA. PMID:20876205

    By a cross-sectional epidemiology study, we attempted to correlate the consumption of tea and/or health supplements, living habits and socio-demographic factors to the prevalence of hypertension among Singaporean Chinese residents. Singaporean Chinese residents aged ⩾40 years were randomly selected and interviewed face-to-face by clinical research assistants. Hypertension was defined as measured systolic blood pressure at least 140 mm Hg and/or diastolic blood pressure at least 90  mmHg or self-reported history/treatment for hypertension. The prevalence of hypertension among the whole investigated population (N=1184, 58.27% females) was 49.73% and the prevalence increased to 66.47% in the sub-population aged ⩾60 years. High risk of hypertension was associated with age ⩾60 years (odds ratio (OR): 4.15-4.19, P25 kg m(-2), OR: 2.10-2.11, Ptea at least 150 ml per week was associated with lower hypertension risk (OR: 0.63, 95% confidence interval (CI): 0.43-0.91, Ptea and British tea was associated with higher reduction in the risk of hypertension (OR: 0.58, 95% CI: 0.39-0.85, Ptea, especially green tea and British tea, was associated with lowering the risk of hypertension. On the other hand, consumption of coffee could be a risk factor of hypertension. These findings may provide useful information for health promotion to reduce risk of hypertension and warrant further study to confirm and elucidate such association.

    Low hemoglobin concentration is associated with increased mortality, but there is disagreement with regard to the clinical definition of anemia. We aimed to evaluate the prevalence, clinical correlates and association with total and cause-specific long-term mortality across the hemoglobin distribution and for previously proposed definitions of anemia. Blood hemoglobin concentration and mean corpuscular volume was measured in participants of the Malmö diet and cancer study-a prospective cohort study, and related to baseline characteristics and outcomes during follow-up. Primary endpoints were all-cause mortality, cardiovascular mortality and cancer-related mortality. A U-shaped association of hemoglobin with total mortality was observed in spline regression analyses, with nadir at hemoglobin 150 g/L among men and 130 g/L among women. Mortality increased steeply with more strict definitions of anemia, hazard ratio: 1.36, 1.94 and 2.16 for hemoglobin macrocytic anemia, which was less prevalent than microcytic and normocytic anemia. Dietary intake of iron and vitamin B12 were significantly lower and use of antithrombotic medications was significantly higher in subjects with anemia. The World Health Organisation definition of anemia was associated with increased mortality (hazard ratio 2.16) but excess mortality was also observed at higher hemoglobin levels. Of morphological subtypes, anemia with macrocytosis was rare but associated with the highest mortality.

    Full Text Available Abstract Background Use of high daily doses of benzodiazepines is generally contraindicated for seniors. While both patient and physician factors may influence the use of high daily doses, previous research on the effect of patient factors has been extremely limited. The objectives of this study were to determine the one year prevalence of use of high daily doses of benzodiazepines, and examine physician and patient correlates of such use among Quebec community-dwelling seniors. Methods Patient information for 1423 community-dwelling Quebec seniors who participated in the Canadian Study of Health and Aging was linked to provincial health insurance administrative data bases containing detailed information on prescriptions received and prescribers. Results The standardized one year period prevalence of use of high daily doses of benzodiazepines was 7.9%. Use of high daily doses was more frequent among younger seniors and those who had reported anxiety during the previous year. Patients without cognitive impairment were more likely to receive high dose prescriptions from general practitioners, while those with cognitive impairment were more likely to receive high dose prescriptions from specialists. Conclusion High dose prescribing appears to be related to both patient and physician factors.

    Full Text Available BackgroundSleep disturbances are common in individuals with diabetes. Patients with diabetes have higher rates of insomnia, excessive daytime sleepiness and increased incidence of restless leg syndrome. The purpose of our study was to investigate the prevalence and determine the predictors of sleep dysfunction in patients with type 2 diabetes in a southeast Asian Indian population.MethodsWe enrolled 120 patients with type 2 diabetes who attended an endocrinology clinic in a tertiary-care hospital. After we collected their demographic data, we recorded their anthropometric measurements. Fasting, postprandial blood glucose values and glycosylated hemoglobin (HbA1c values were then obtained. Quality of sleep was evaluated in all the patients through the Pittsburgh Sleep Quality Index (PSQI, which is a questionnaire that assesses sleep quality and disturbances over a monthlong period. A Global Sleep Quality score ≥5 discriminates between good and poor sleepers.ResultsThe mean global PSQI score was 7.08 (standard deviation, 3.89, which suggested poor sleep quality in this population. Sixty-nine percent of patients had a global PSQI score ≥5, indicating that they were "poor sleepers." The global PSQI score positively correlated with the duration of diabetes and was also independent of other variables such as age, gender, body mass index, HbA1c, or medications.ConclusionWe found a high prevalence of sleep dysfunction in patients with type 2 diabetes. We also found a significant correlation between duration of diabetes and quality of sleep, independent of other variables. It is important for physicians to address the quality and duration of sleep in patients with type 2 diabetes.

    This study was designed to see the prevalence of lactose intolerance and symptom correlation following oral lactose challenge in healthy volunteers in the north east part of Bangladesh. Symptoms of abdominal pain, nausea, borborygmi, flatulence, diarrhea and others were noted for 24 hours and blood glucose was estimated at 0 hour and 30 minutes after 50 gm oral lactose load to healthy volunteers. Failure to rise blood glucose level ≥1.1 mmol/l at 30 minutes after lactose intake from fasting level was taken as lactose malabsorption (LM) i.e., lactose intolerance. Sensitivity and specificity of different symptoms were then found out. A total of 171 volunteers (male 123, female 48) with a mean age 34.08 years participated in this study. Lactose intolerance was found among 82.5% (n=141, M=100, F=41) subjects. Symptoms mostly experience by the lactose malabsorbers were diarrhea 93(66.0%), borborygmi 80(56.7%), abdominal pain 31(22.0%) and flatulence 32(22.7%). LM prevalence was found to increase with increasing number of symptoms up to 3 symptoms. A week positive correlation (r=0.205, P=0.007) was found between the number of symptoms and proportion of subjects having positive lactose tolerance test. Lactose intolerance among healthy adults of North East part of our country is as common as in other Asian countries including China and Malaysia. But LM is higher than that of Europeans and south Indians. Diarrhea and borborygmi were mostly associated with LM.

    Full Text Available Introduction: Men who have sex with men (MSM in developing countries such as Mexico have received relatively little research attention. In Tijuana, Mexico, a border city experiencing a dynamic HIV epidemic, data on MSM are over a decade old. Our aims were to estimate the prevalence and examine correlates of HIV infection among MSM in this city. Methods: We conducted a cross-sectional study of 191 MSM recruited through respondent-driven sampling (RDS in 2012. Biological males over the age of 18 who resided in Tijuana and reported sex with a male in the past year were included. Participants underwent interviewer-administered surveys and rapid tests for HIV and syphilis with confirmation. Results: A total of 33 MSM tested positive for HIV, yielding an RDS-adjusted estimated 20% prevalence. Of those who tested positive, 89% were previously unaware of their HIV status. An estimated 36% (95% CI: 26.4–46.5 had been tested for HIV in the past year, and 30% (95% CI: 19.0–40.0 were estimated to have ever used methamphetamine. Independent correlates of being infected with HIV were methamphetamine use (odds ratio [OR]=2.24, p=0.045, 95% CI: 1.02, 4.92 and active syphilis infection (OR=4.33, p=0.01, 95% CI: 1.42, 13.19. Conclusions: Our data indicate that MSM are a key sub-population in Tijuana at higher risk for HIV. Tijuana would also appear to have the highest proportion among upper-middle-income countries of HIV-positive MSM who are unknowingly infected. More HIV prevention research on MSM is urgently needed in Tijuana.

    We investigate the prediction of the future prices from the structures and the networks of the companies in special financial groups. After the financial group network has been constructed from the value of the high cross-correlation, each company in a group is simulated and analyzed how it buys or sells stock is anaylzed and how it makes rational investments is forecasted. In the shortmemory behavior rather than the long-memory behavior, each company among a group can make a rational investment decision by using a stochastic evolution rule in the financial network. In particular, we simulate and analyze the investment situation in connection with the empirical data and the simulated result.

    This study investigated HPA and vagal functioning as correlates of parenting in mothers of 175 six-month-old children. Salivary cortisol indexed HPA functioning and respiratory sinus arrhythmia (RSA) reduction indexed vagal regulation. Positive engagement and negative intrusiveness were observed during the Face-to-Face Still Face Paradigm (FFSFP) reunion and a semi-structured free play episode. Mixed modeling was used to examine differences in maternal behaviors across contexts as a function of psychophysiology. Main effects of cortisol levels, as well as interactions with RSA reduction and context, predicted negative intrusiveness. Mothers with high cortisol exhibited more negative intrusiveness if they also had lower RSA reduction. Mothers were also less negatively intrusive during the FFSFP than the free play if they had lower cortisol levels. There were no associations between psychophysiological measures and positive engagement. The findings suggest: (1) that parenting behaviors are associated with maternal stress physiology; (2) considerations of single physiological systems related to parenting behaviors may be incomplete; and (3) type and context of behaviors must be considered when examining biobehavioral associations with parenting.

  11. Longtime Behavior for Mutually Catalytic Branching with Negative Correlations

    In several examples, dualities for interacting diffusion and particle systems permit the study of the longtime behavior of solutions. A particularly difficult model in which many techniques collapse is a two-type model with mutually catalytic interaction introduced by Dawson/Perkins for which they proved under some assumptions a dichotomy between extinction and coexistence directly from the defining equations. In the present article we show how to prove a precise dichotomy for a related model with negatively correlated noises. The proof combines a self-duality to ensure uniform integrability via moment bounds on exit-times of correlated Brownian motions from the first quadrant and explicit second moment calculations. Since the uniform integrability bound is independent of the branching rate our proof can be extended to infinite branching rate processes.

    Full Text Available Studies of men who have sex with men (MSM in diverse geographic and cultural contexts have identified health challenges affecting this population. MSM might be particularly vulnerable to sexual victimization and forced sex. The aim of this research study was to examine prevalence of sexual victimization and correlates of forced sex among Japanese MSM. We recruited a sample of 5,731 Japanese MSM who completed an internet-administered survey. Participants reported on history of different types of sexual victimization, unprotected anal sex, other health risk behaviors, exposure to gay-related teasing and bullying, depression, and suicidality. Over one-fifth of the sample (21.4% reported experiencing at least one form of sexual victimization, and 8.7% reported a history of forced sex. MSM who had ever experienced forced sex were significantly more likely to report experiencing psychological risks (depression OR = 1.55, 95% CI = 1.28-1.89; attempted suicide OR = 2.25, 95% CI = 1.81-2.81; other forms of bullying OR = 1.38, 95% CI = 1.13-1.68 and other behavioral risks (unprotected anal sex OR = 1.56, 95% CI = 1.29-1.90; sex venue attendance OR = 1.27, 95% CI = 1.04-1.54; methamphetamine use OR = 1.57, 95% CI  = 1.05-1.36, compared to MSM who had not experienced forced sex. Efforts to develop holistic and integrated health services for Japanese MSM are warranted, particularly related to psychosocial determinants of HIV prevention. However, due to cultural factors that emphasize familial and social relations and that stigmatize same-sex behavior, Japanese MSM might experience challenges to seeking social support and health services. Interventions must be provided in safe and non-judgmental settings where Japanese MSM feel comfortable disclosing their health and social support needs.

    Representative samples of the Czech population were surveyed with regard to sexual behavior in 1993, 1998, 2003, and 2008 (N = 7,720). Lifetime prevalence of Heterosexual Anal Intercourse increased from 1993 to 2008 (16.6% to 19.7% among women, 15.7% to 25.3% among men). Anal intercourse was associated with lifetime number of sex partners, current masturbation, and histories (prevalence of which increased from 1993 to 2008) of homosexual sex, prostitution, venereal disease (adjusted for number of sex partners), and women's sexual dysfunction. The authors discuss the possible reasons for the increasing prevalence and the associations. Multivariate predictors of ever having a sexual dysfunction or a venereal disease are also presented.

    The aim of this study was to investigate the presence of premorbid Personality Disorder (PD) and its relationship with clinical correlates in patients with Delusional Disorder (DD). Eighty-six outpatients with DD whose diagnoses were confirmed using the Structured Clinical Interview for DSM-IV Axis I (SCID-I) Disorders (psychosis module) were evaluated for premorbid PD utilizing the Standardized Assessment of Personality (SAP). Psychopathology was assessed using Module B of SCID-I and the Positive and Negative Syndrome Scale (PANSS); psychosocial functioning was evaluated with the Global Assessment of Functioning scale. Premorbid intelligence was assessed using the Wechsler Adult Intelligence Scale-Third Edition, vocabulary subtest. A sociodemographic-clinical questionnaire was completed. Sixty-four percent of the patients had at least one premorbid PD, the most common being paranoid PD (38.4%), followed by schizoid PD (12.8%). The presence of at least one premorbid PD was significantly associated with higher scores for psychopathology, in particular, on the affective dimension of DD symptoms. However, the presence of premorbid PD was not associated with psychosocial functioning. Each of the premorbid PD was associated with different psychopathological profiles. Premorbid PD is a relevant phenomenon in DD, given its high prevalence and comorbidity, its influence on clinical correlates and its potential ability to predict specific sub-syndromes.

    Background Agua celeste, or “heavenly water,” is the street name for a sky-blue colored solvent reportedly inhaled or ingested to produce an intoxicating effect. Study aims were to (1) describe prevalence of Agua Celestse (AC) use, and (2) identify correlates of lifetime and recent use of AC use among female sex workers who also inject drugs (FSW-IDUs) in northern Mexico. Methods Between 2008 and 2010, baseline data from FSW-IDUs ≥ 18 years old living in Tijuana or Ciudad Juarez participating in a longitudinal behavioral intervention were analyzed using logistic regression. Results Among 623 FSW-IDUs (307 from Tijuana and 316 from Ciudad Juarez (CJ)), 166 (26%) reported ever using AC, all of whom lived in CJ. Among the CJ sample, lifetime prevalence of AC use was 53%, median age of first use was 16 years (IQR: 14–23), and 10% reported it as their first abused substance. Ever using AC was independently associated with ever being physically abused and younger age, and was marginally associated with initiating injection drug use and regular sex work at age eighteen or younger. Among those ever using AC, 70/166 (42.2%) reported using it within the last 6 months, which was independently associated with using drugs with clients before or during sex, being on the street more than 8 hours per day, and younger age. Discussion We observed considerable geographic variation in the use of AC in northern Mexico. Future studies exploring factors influencing use, its precise formulation(s), and its potential health effects are needed to guide prevention and treatment. PMID:21441001

    Full Text Available The aim of this study was to analyze the influence of socio-behavioral variables on the prevalence and severity of dental caries in 4- to 6-year-old children. A cross-sectional study was performed on a sample of 1993 children enrolled in 58 public preschools from Araçatuba City, São Paulo State, Brazil, during 2010. The exams were made using the decayed, missing, and filled teeth index (World Health Organization methodology and detection criteria for non-cavitated lesions. A tested, self-administered questionnaire was sent to parents to obtain information about their socio-behavioral characteristics. Standardization was performed to verify concordance among examiners (kappa = 0.84. The prevalence of cavitated caries lesions was 41.2% (821, and the prevalence of both, cavitated and non-cavitated caries lesions, was 43.9% (875. The means ± standard deviations of the decayed, missing, and filled teeth index for children aged 4, 5, and 6 years were 1.18 ± 2.45, 1.65 ± 2.67, and 1.73 ± 2.77, respectively. Caries were significantly more prevalent in children from families with low incomes and low educational levels. The presence of dental caries was associated with access to dental services (p < 0.05. The associations between both, cavitated and non-cavitated dental caries lesions, and the frequency of oral hygiene were statistically significant. The prevalence of dental caries in preschoolers was strongly associated with factors related to the children's parents. Therefore, information about parents' socio-economic status, behaviors, and attitudes in relation to oral health should be considered when planning prevention and educational programs for the oral health of preschool children.

    This study examined neural correlates of empathy in adolescence while observing harmful acts. A total of 32 participants (aged 12-19 years) viewed pictures depicting negative (offenders inflicting intentional harm) and positive (friends socializing) social situations. After viewing each picture, participants could allocate hypothetical points to either the offender or the victim in a dictator game. Behaviorally, participants of all ages acted prosocially towards victims, fairly towards positive individuals and punishingly towards offenders. Brain imaging analyses showed that viewing negative situations was associated with more activation in the bilateral intraparietal lobule and the superior temporal sulcus (STS), whereas viewing positive situations was associated with more medial prefrontal cortex and left temporal parietal junction activity. Analyses testing for associations between brain activity and self-reported empathy showed that the STS was correlated negatively with reports of understanding others' distress and the willingness to help others. Together, the findings suggest that adolescents show similar prosocial behavior, as previously reported in adults with greater STS activity, when observing negative social acts that is modulated by an individual's empathy for others.

    Objective: To analyze the prevalence and factors associated with the co-occurrence of health risk behaviors in adolescents. Methods: A cross-sectional study was performed with a sample of high school students from state public schools in Pernambuco, Brazil (n=4207, 14-19 years old). Data were obtained using a questionnaire. The co-occurrence of health risk behaviors was established based on the sum of five behavioral risk factors (low physical activity, sedentary behavior, low consumption of fruits/vegetables, alcohol consumption and tobacco use). The independent variables were gender, age group, time of day attending school, school size, maternal education, occupational status, skin color, geographic region and place of residence. Data were analyzed by ordinal logistic regression with proportional odds model. Results: Approximately 10% of adolescents were not exposed to health risk behaviors, while 58.5% reported being exposed to at least two health risk behaviors simultaneously. There was a higher likelihood of co-occurrence of health risk behaviors among adolescents in the older age group, with intermediate maternal education (9-11 years of schooling), and who reported living in the driest (semi-arid) region of the state of Pernambuco. Adolescents who reported having a job and living in rural areas had a lower likelihood of co-occurrence of risk behaviors. Conclusions: The findings suggest a high prevalence of co-occurrence of health risk behaviors in this group of adolescents, with a higher chance in five subgroups (older age, intermediate maternal education, the ones that reported not working, those living in urban areas and in the driest region of the state).

    Abstract Objective: Verify the prevalence and sociodemographic and economic factors associated with behavior change stages for habitual physical activity practice in adolescents from Santa Catarina. Methods: Secondary analysis of a study on the Behavior of Adolescents from Santa Catarina (CompAC 2). Cross-sectional school-based study of 6,529 high-school students (males, n=2,903) from the state of Santa Catarina public education system in 2011, aged 15 to 19 years. Multinomial logistic regression (crude and adjusted) was used to measure the association. Results: The highest and lowest prevalence rates were found in the maintenance (43.9%) and precontemplation stages (7.0%), respectively. The stages of action, preparation and contemplation showed similar results: 16.2%; 17.0% and 15.6%; respectively. Male adolescents show higher prevalence in the maintenance stage in relation to females and these show a higher prevalence in preparation, contemplation and precontemplation. All the assessed variables (gender, age, area of residence, employment status, family income, maternal education and school grade), with the exception of school shift, were associated with at least one of the stages. Conclusions: A large proportion of adolescents are in the pre-adoption stages and most of these have the intention to start regular physical activity. With the exception of school shift, the assessed variables were associated with stages in different ways, showing different profiles in relation to sociodemographic and economic characteristics in each subgroup.

    2004-01-01

    Cross-sectional data were collected on substance use behaviors and potential correlates in 1,494 African American students enrolled in grades 5-12 in eight schools in a central Alabama school district. Using a risk and asset framework, self-reported recent alcohol, cigarette, and marijuana use were analyzed by identifying and measuring levels of influence, including individual, family, and school. For alcohol and marijuana use, recurrent risk factors were age, being hit by a parent, affiliation with gangs, and a tolerant attitude of peers toward drug use. For cigarette use, risk factors were peer-oriented: associations with gangs or cohorts holding lenient attitudes about substance use. For all substances, salient asset factors were academic achievement and parental monitoring. Findings suggest that efforts to reduce substance use behaviors should be directed at adolescents in terms of academic achievement and grade level as well as their social environments. For the latter, peer/family risks and family/school assets should be the foci for programs to minimize the short- and long-term consequences of these behaviors. Hence, the emphasis should be placed on modeling attitudes, preventing gang and family violence, encouraging parental supervision, and building positive teacher-student interactions.

Studies on the prevalence and correlates of physical disability and functional limitation among elderly Nigerians are scanty. Methodology. This is a community-based cross-sectional study conducted in 3 local government areas (LGAs in Nigeria, using a multistage sampling technique. Functional limitations of 1824 elderly persons were tested using Tinetti performance-oriented mobility assessment tool (TPOMAT and self-reported activities of daily living (ADL. ADL disability of ten, six, and five basic items were compared. Results. The prevalence ratios (PRs of physical disability using the ten, six, and five basic ADL items were 28.3 (95% CI 25.2–31. 5, 15.7 (95% CI 13.4–19.8, and 12.1 (95% CI 9.8–15.3, respectively, while functional limitation was 22.5 (95% CI 18.1–24.4. Increased risk of disability was independently associated with female gender PR 3.6 (95% CI 1.5–7.4, advanced age ≥75 years; PR 22.2 (95% CI 14.5, 36.8, arthritis PR 3.7 (95% CI 2.6–4.6, stroke PR 4.8 (95% CI 3.7–7.9 and diabetes PR 6.1 (95% CI 4.3–7.1.

    Full Text Available One of the identified risk factors for anxiety disorders in adolescence and adulthood is inhibited behaviors in childhood. The present study sought to examine the relationship between behavioral inhibition with some of the internal (personal and external (family environment factors in a sample of preschool children in kindergartens. In a cross sectional study in 2009, data was collected trough a structured questionnaire completed by parents and teachers in day-care centers. A total of 1403 children were assessed. Analysis was performed through complex sample analysis. The results showed that 7.4% (CI95%= 6.1%-9.1% of children according to parents' and 8.1% (CI95%= 6%- 10.7% according to teachers' evaluation classified as behaviorally inhibited. The higher levels of behavioral inhibition were shown by girls, first children, single parent families and older children. Birth year before 2004, birth rank, living in a single parent family and maternal level of education were independent predictors for behavioral inhibition in logistic regression modeling. There is relatively high prevalence of inhibited behaviors among Iranian children. Further examination of diagnosed children with behavioral inhibition by experienced psychiatrists is needed. Also establishing consultation centers for behaviorally inhibited children and instructing their parents and teachers are recommended.

    Full Text Available Children of depressed mothers have impaired cognitive, behavioral, and health outcomes from infancy through adulthood, and are especially at risk when maternal depression persists over multiple years. But there are several important limitations to our current descriptive knowledge about maternal depression, especially depression among unmarried mothers. Data from the Fragile Families and Child Wellbeing Study, a recent cohort of children born in urban areas to mostly unmarried parents (N = 4,366, was used to examine the prevalence and correlates of maternal depression when children were about 1, 3, 5, and 9 years old. Results show that, at any given survey wave, between 16% and 21% of mothers reported depression. Nearly two-fifths (38% of mothers reported depression at least once during the eight-year period, and 7% reported persistent depression (depression at three or four of the four survey waves. Employment status, relationship status, and fathers' depression were among the sociodemographic characteristics most robustly associated with both stability and change in maternal depression. Given the important social consequences of maternal depression, not least of which is impaired wellbeing among children of depressed mothers, prevention and treatment of maternal depression should be an imperative for researchers, clinicians, and policymakers alike.

    Highlights: • Various thoracic CT findings, including cysts, mediastinal masses, etc. were found. • Cysts show upper and peripheral dominant distribution. • The number, size, and distribution of the pulmonary cysts in NF-1 revealed significant correlation. • It is suspected that thoracic CT findings in NF-1 occur independently. - Abstract: Purpose: To evaluate the prevalence rates and the correlations of thoracic computed tomography (CT) findings of neurofibromatosis 1 (NF1) in 88 patients. Materials and methods: Chest CT images of 88 NF1 patients were independently reviewed by three observers, and the CT findings were evaluated. If abnormal findings were present, their number, size, and distribution were recorded. The prevalence rate of each CT finding was calculated, and the correlations between CT findings were analyzed. Results: Of the 88 cases, 13 were positive for cysts, 16 for emphysema, 8 for nodules, 8 for GGNs (ground glass nodules), 13 for mediastinal masses, 20 for scoliosis, 44 for subcutaneous nodules, and 34 for skin nodules. Cysts showed upper and peripheral dominant distributions. Regarding 13 mediastinal masses, 2 were diagnosed as malignant peripheral nerve sheath tumors (MPNSTs), 1 was diagnosed as primary lung cancer, 2 were diagnosed as lateral meningocele, 3 were diagnosed as neurofibromas, and the remaining 7 were considered neurofibromas. There was a significant correlation between the prevalence of subcutaneous nodules and that of skin nodules. Significant positive correlations were also seen between size and number, size and rate of central distribution, and number and rate of central distribution of cysts. Conclusion: Various CT findings were found in NF-1 patients, and the prevalence rates of subcutaneous and skin nodules were higher than other findings. Though the prevalence rates of subcutaneous nodules and skin nodules were significantly correlated, the other CT findings in NF-1 occurred independently. The number, size, and

    Full Text Available Chronic heart failure (CHF is one of the most common complications of cardiovascular disease. According multicenter studies conducted during recent years, coronary heart disease was the leading cause of heart failure and has been on average 64% of patients with chronic heart failure. The tight functional relationship of cardiovascular and urinary system causes a lot of interest to the functional state of kidneys in various cardiovascular diseases. Most risk factors for cardiovascular disease are common risk factors of renal failure.

    Full Text Available Objective Sleep disorders in Parkinson’s disease are very common. Polysomnography (PSG is considered the gold standard for diagnosis. The aim of the present study is to assess the prevalence of nocturnal sleep disorders diagnosed by polysomnography and to determine the associated clinical factors. Method A total of 120 patients with Parkinson’s disease were included. All patients underwent a standardized overnight, single night polysomnography. Results Ninety-four (78.3% patients had an abnormal PSG. Half of the patients fulfilled criteria for sleep apnea-hypopnea syndrome (SAHS; rapid eye movement behavior disorder (RBD was present in 37.5%. Characteristics associated with SAHS were age (p = 0.049 and body mass index (p = 0.016. Regarding RBD, age (p < 0.001, left motor onset (p = 0.047 and levodopa equivalent dose (p = 0.002 were the main predictors. Conclusion SAHS and RBD were the most frequent sleep disorders. Higher levodopa equivalent dose and body mass index appear to be risk factors for RBD and SAHS, respectively.

    Full Text Available Abstract Background Focusing 50 year olds and above, this study assessed the frequency, extent and correlates of tooth loss due to various reasons. Frequency and correlates of posterior occluding support was also investigated. Method A cross-sectional household survey was conducted in Pwani region and in Dar es Salaam in 2004/2005. One thousand and thirty-one subjects, mean age 62.9 years participated in a clinical examination and completed interviews. Results The prevalence of tooth loss due to any reason was 83.5 %, due to caries 63.4% and due to other reasons than caries, 32.5%. A total of 74.9% had reduced number of posterior occluding units. Compared to subjects having less than 5 teeth lost due to caries, those with 5 or more lost teeth were more likely to be females, having decayed teeth, confirming dental attendance and to be among the least poor residents. Compared to subjects who had lost less than 5 teeth due to reasons other than caries, those who had lost 5 or more teeth were more likely to be of higher age, having mobile teeth, being males, being very poor and to disconfirm dental attendance when having problems. Predictors of prevalence of tooth loss (1 or more lost tooth due to various reasons and reduced number of occluding units followed similar patterns of relationships. Conclusion The results are consistent with prevalence and extent of tooth loss due to caries and due to reasons other than caries being differently related to disease- and socio- behavioral risk indicators. Caries was the principle cause of tooth loss and molar teeth were the teeth most commonly lost.

    The aims of this study were to examine the prevalence and correlates of psychological distress among older women living with HIV in comparison to their male counterparts and younger women and to identify the sociodemographic and disease-related factors associated with psychological distress. The sample consisted of 508 HIV-infected patients (65 older women, 323 women aged below 50 years, and 120 older men) recruited from 10 Portuguese hospitals. Data regarding psychological distress were collected using the Brief Symptom Inventory (BSI). Seven older women (10.8%), eight older men (6.7%), and 61 younger women (18.9%) reported a T-score ≥ 63 for global severity index (GSI), indicative of a need for further psychological evaluation. Overall, younger women reported significantly higher psychological distress than older men. The odds of having clinically significant psychological distress score were significantly lower for older women reporting sexual transmission, while for younger women, having other co-infections was a significant correlate of higher psychological distress. Younger women were 2.67 (95% CI: 1.22-5.84) times more likely to report psychological distress than were older men. The odds were not significantly different from older women. This study shows that older women do not differ substantially from younger women and older men in terms of psychological distress. The results reinforce, however, that mental health interventions should be tailored to reflect individuals' circumstances as well as developmental contexts. Moreover, they draw attention to the importance of examining resilience characteristics in older adults to understand the mechanisms behind 'successful ageing' while living with HIV.

    Full Text Available Despite increased awareness and concern about children with developmental disabilities wandering away from adult supervision, there is a paucity of research about elopement. This is the first study to examine and report the prevalence and correlates of elopement in a nationally representative sample of school-age children in the United States with an autism spectrum disorder (ASD and/or cognitive impairment. Data were obtained from the CDC's "Pathways" Survey, a follow-up telephone survey of the parents of 4,032 children with a developmental condition. 3,518 children that had ASD, intellectual disability (ID, and/or developmental delay (DD at the time of survey administration were included for analysis. Children were divided into three condition groups: ASD-only; ID/DD-only; ASD+ID/DD. Logistic regression analyses were used to compare the prevalence of elopement and rates of preventive measure use (barriers and/or electronic devices across condition groups, and to examine the clinical and demographic correlates of elopement. T-tests were also performed to compare scores on the Children's Social Behavior Questionnaire (CSBQ between wanderers and non-wanderers. Overall, 26.7% of children had reportedly eloped within the previous year, most commonly from public places. Children with ASD-only and ASD+ID/DD were more likely to have eloped than those with ID/DD-only. Across all groups, wanderers scored higher than non-wanderers on five out of six CSBQ subscales; they were more likely not to realize when there is danger, to have difficulty distinguishing between strangers and familiar people, to show sudden mood changes, to over-react to everything/everyone, to get angry quickly, to get lost easily, and to panic in new situations or if change occurs. Even after controlling for elopement history, parents of children in the ASD+ID/DD group were more likely than those in the other condition groups to report using physical or electronic measures to prevent

    This study was designed to determine the incidence and prevalence of amputations in diabetic Mexican American elders and to identify correlates of lower extremity amputations. Data for this study came from baseline and two follow-up interviews of the Hispanic Established Population for the Epidemiological Study of the Elderly (EPESE) conducted in five southwestern states (Texas, California, New Mexico, Colorado and Arizona) in 1993-1994. Of the 3050 subjects aged 65 and older, 690 reported diabetes, and from these, 60 (8%) reported having at least one lower extremity amputation. Losing a leg was the most common type of amputation (53%). Twelve percent of respondents reported a new amputation and 40% of amputees reported a second amputation during follow-up. Mortality among amputees was 46% during a 5-year follow-up. Multiple logistic regression analysis showed that being male and having eye problems, hip fracture and diabetes for 10 or more years were significantly associated with lower extremity amputations at baseline, whereas obesity, stroke and 10 or more years with diabetes were significantly associated with new amputations at 5-year follow-up. Gender and disease history were associated with lower extremity amputations at baseline and follow-up. These variables may be useful in developing patient education and intervention programs.

    This study aims to assess the prevalence of depression and examine potential risk factors correlated to depression among nursing college students in China. Between September and November 2012, a total of 763 college nursing students were randomly selected to participate in a survey, which included the Center for Epidemiologic Studies Depression Scale (CES-D). The result showed that 22.9% (95% CI: 20.0%-25.9%) of participants reported high score on the CES-D (16 or above). Risk factors significantly associated with depression in the univariate analysis were academic performance, academic stress, interest in majors, occupational future, interpersonal relationship, frequency of exercise, self-reported health status, social support, educational level of father, relationship with parents and making decisions without interference by parents. Backward multivariate logistic regression analysis revealed that lower academic stress, and better occupational future were strongly related to lower risk of depression, followed by active use of social support, full making decision power, better relationship with father and higher self-reported health status. The findings suggested that in order to prevent depression among college nursing students, school- and family-based strategies should be developed and implemented.

    Migrant workers comprise 80% of the population of the United Arab Emirates, but there is little research on their mental health. To determine the prevalence and correlates of depression among workers living in labor camps, we conducted a cross-sectional survey in labor camps in Al Ain city. The Depression Anxiety and Stress Scale (DASS-42) was used to assess depression and suicidal ideation among the study participants. Off the 319 contacted workers agreed to participate, however 239 fully completed the DASS-42. The prevalence of a score >=10 ("depression") was 25.1% (60/239). Depression was correlated with physical illness (97/301), (adjusted odds ratio-AOR = 2.9; 95% CI 2.26-5.18), working in construction industry (prevalence 124/304), AOR = 2.2; 95%CI 1.56-3.83), earning less than 1,000 UAE Dirham per month (prevalence 203/314), (AOR = 1.8; 95%CI 1.33-3.16), and working more than 8 h a day (prevalence 213/315), (AOR = 2.7; 95%CI 1.19-6.27). 20/261 (6.3%) of the study participants reported thoughts of suicide and 8/265 (2.5%) had attempted suicide. People with suicidal ideation were more likely to have a physical illness (AOR = 8.1, 95%CI 2.49-26.67), earn less than 1,000 UAE Dirham per month (AOR = 5.98, 95%CI 1.26-28.45), and work for more than 8 h a day (AOR = 8.35, 95%CI 1.03-67.23). The study identified self reported indicators of a substantial burden of depression, and thoughts of self-harm among laborers surveyed. Policy level intervention and implementation, is needed to improve working conditions, including minimum wages and regulation of working hours is recommended.

    This study aimed to assess patterns of sexual activity, preventive behaviors, contraceptive use, and the prevalence of chlamydia infection in student populations from two countries. 188 asymptomatic students of the University of Bielefeld, Germany and 590 students of the Navarra Public University, Spain were surveyed using a standardized self-administered questionnaire. Urine samples were analyzed by ligase chain reaction technique for chlamydia infection. Compared to German students, Spanish students were less likely to have more than one sex partner within the last 12 months (OR: 0.62; CI: 0.46-0.83), to have sexual intercourse more than one time per week (OR: 0.70; CI: 0.52-0.93) and to use oral contraceptives (OR: 0.16; CI: 0.10-0.26). They reported a higher use of condoms (OR: 2.93; CI: 2.01-4.27) and were more likely to always use condoms with a new sex partner (OR: 2.47; CI: 1.72-3.53). The prevalence of chlamydia infection was considerably higher in German students (5.8% [corrected] in females; 2.2% in males) than in Spanish students, where no case was found. The higher frequency of sexual activity, a higher engagement in risk-taking sexual behavior and the lower use of barrier contraceptives may contribute to the higher prevalence of chlamydia infection in German students.

    Full Text Available Introduction: Police officers are at an elevated risk for needle-stick injuries (NSI, which pose a serious and costly occupational health risk for HIV and viral hepatitis. However, research on NSIs among police officers is limited, especially in low- and middle-income countries. Despite the legality of syringe possession in Mexico, half of people who inject drugs (PWID in Tijuana report extrajudicial syringe-related arrests and confiscation by police, which has been associated with needle-sharing and HIV infection. We assessed the prevalence and correlates of NSIs among Tijuana police officers to inform efforts to improve occupational safety and simultaneously reduce HIV risks among police and PWID. Methods: Tijuana's Department of Municipal Public Safety (SSPM is among Mexico's largest. Our binational, multi-sectoral team analyzed de-identified data from SSPM's 2014 anonymous self-administered occupational health survey. The prevalence of NSI and syringe disposal practices was determined. Logistic regression with robust variance estimation via generalized estimating equations identified factors associated with ever having an occupational NSI. Results: Approximately one-quarter of the Tijuana police force was given the occupational health survey (N=503. Respondents were predominantly male (86.5% and ≤35 years old (42.6%. Nearly one in six officers reported ever having a NSI while working at SSPM (15.3%, of whom 14.3% reported a NSI within the past year. Most participants reported encountering needles/syringes while on duty (n=473, 94%; factors independently associated with elevated odds of NSIs included frequently finding syringes that contain drugs (adjusted odds ratio (AOR: 2.98; 95% confidence interval (CI: 1.56–5.67 and breaking used needles (AOR: 2.25; 95% CI: 1.29–3.91, while protective factors included being willing to contact emergency services in case of NSIs (AOR: 0.39; 95% CI: 0.22–0.69, and wearing needle-stick resistant

  20. Reducing Anemia Prevalence in Afghanistan: Socioeconomic Correlates and the Particular Role of Agricultural Assets.

    Full Text Available This research aims to examine the socio-economic correlates of anemia in women, and potential sources of iron in household diets in Afghanistan. It also examines whether ownership of agricultural (particularly livestock assets and their use in food production has a role in alleviating anaemia, especially where local markets may be inadequate. We analyse data from the 2010/11 Afghanistan Multiple Indicator Cluster Survey, estimating a logistic regression to examine how anemia status of women is associated with socio-economic covariates. A key result found is that sheep ownership has a protective effect in reducing anemia (prevalence odds ratio of sheep ownership on anemia of 0.83, 95% confidence interval (CI: 0.73-0.94 after controlling for wealth and other covariates. This association is found to be robust to alternative model specifications. Given the central role of red meat in heme iron provision and absorption of non-heme iron, we hypothesise that sheep ownership promotes mutton consumption from own-production in a setting where market-sourced provision of nutritious food is a challenge. We then use the 2011/12 National Risk and Vulnerability Assessment household data to understand the Afghan diet from the perspective of dietary iron provision, and to understand interactions between own-production, market sourcing and mutton consumption. Sheep ownership is found to increase the likelihood that a household consumed mutton (odds ratio of 1.27, 95% CI: 1.15-1.42, the number of days in the week that mutton was consumed (prevalence rate ratio of 1.24. 95% CI: 1.12-1.37 and the quantity of mutton consumed (7 grams/person/week. In the subsample of mutton consumers, households sourcing mutton mostly from own production consumed mutton 1.5 days more frequently on average than households relying on market purchase, resulting in 100 grams per person per week higher mutton intake. Thus this analysis lends support to the notion that the linkage between

    Full Text Available Abstract Background Socioeconomic changes have led to profound changes in individuals' lifestyles, including the adoption of unhealthy food consumption patterns, prevalent tobacco use, alcohol abuse and physical inactivity, especially in large cities like Ho Chi Minh City (HCMC. The Stepwise Approach to Surveillance of Non-communicable Disease Risk Factors survey was conducted to identify physical activity patterns and factors associated with 'insufficient' levels of physical activity for health in adults in HCMC. Methods A cross-sectional survey was conducted in 2005 among 1906 adults aged 25–64 years using a probability proportional to size cluster sampling method to estimate the prevalence of non-communicable disease risk factors including physical inactivity. Data on socioeconomic status, health behaviours, and time spent in physical activity during work, commuting and leisure time were collected. Physical activity was measured using the validated Global Physical Activity Questionnaire (GPAQ. Responders were classified as 'sufficiently active' or 'insufficiently active' using the GPAQ protocol. Correlates of insufficient physical activity were identified using multivariable logistic regression. Results A high proportion of adults were physically inactive, with only 56.2% (95% CI = 52.1–60.4 aged 25–64 years in HCMC achieving the minimum recommendation of 'doing 30 minutes moderate-intensity physical activity for at least 5 days per week'. The main contributors to total physical activity among adults were from working and active commuting. Leisure-time physical activity represented a very small proportion (9.4% of individuals' total activity level. Some differences in the pattern of physical activity between men and women were noted, with insufficient activity levels decreasing with age among women, but not among men. Physical inactivity was positively associated with high income (OR = 1.77, 95% CI = 1.05–2.97 and high household

    Humankind and the planet face many thorny environmentally related challenges that require a range of responses, including changing behaviors related to transportation, eating habits, purchasing, and myriad other aspects of life. Using data from a 1201-person survey and 14 Community Listening Sessions (CLSs), we explore people's perceptions of and actions taken to protect the environment. Our data indicate a striking prevalence of waste management-related actions. Survey respondents described actions and concerns related to trash, recycling, and composting as the most common environmental behaviors; similarly, participants in CLSs discussed waste-related topics, for which we did not prompt, as frequently as those topics for which we specifically prompted. Explanations for this prevalence emerging from the data include (1) the nature of waste-related behaviors (concrete, supported by infrastructure, simple, compatible with lifestyle); (2) norms and social dynamics (family interactions, feelings of belonging/participation, government policy); and (3) internal psychological processes (internalized norms and environmental concern). We also found that many waste-related discussions were relatively superficial, focusing on immediate waste-related issues (e.g., litter or recycling) rather than larger issues such as consumption. Our results may provide insight into future efforts to encourage pro-environmental behavior. Given that most pro-environmental behavior involves tasks more complex and lifestyle-changing than those related to simple aspects of waste management, we suggest focusing on the latter two intertwined categories that our data suggest are important: encouraging social dynamics and related development of norms concerning environmental behavior (category 2), and fostering internalized norms and environmental concern (category 3).

To identify and characterize individuals holding misperceptions around their weight status, it may be informative for clinicians to assess self-reported body mass index (BMI classification (ie, underweight, normal, overweight, obese in addition to clinical weight measurement. Methods: Self-reported weight classification data from the 2007 Current Visit Information – Child and Adolescent Survey collected at Mayo Clinic in Rochester, MN, were compared with measured clinical height and weight for 2,993 adolescents. Results: While, overall, 74.2% of adolescents accurately reported their weight status, females, younger adolescents, and proxy (vs self reporters were more accurate. Controlling for demographic and behavioral characteristics, the higher an individual's BMI percentile, the less likely there was agreement between self-report and measured BMI percentile. Those with high BMI who misperceive their weight status were less likely than accurate perceivers to attempt weight loss. Conclusion: Adolescents’ and proxies’ misperception of weight status increases with BMI percentile. Obtaining an adolescent's self-perceived weight status in addition to measured height and weight offers clinicians valuable baseline information to discuss motivation for weight

    Exploratory behavior in the wild is fundamentally linked to an animal's survival and natural life history. The ability to gather information about their environment, establish territories, assert dominance, communicate information regarding reproductive status and locate mates are closely associated with a range of exploratory behaviors. Understanding how these behaviors are performed within the captive setting is crucial in order to create a captive environment in which these behaviors can be expressed, and their function conserved. The objective of this research was to highlight the factors of captive husbandry and management that influence the occurrence of exploratory behaviour of cheetahs (Acinonyx jubatus) in captivity. One hundred and twelve cheetahs in 88 enclosures across nine zoological institutions in five countries were the subjects of this study. The presence of raised areas, number of movements between enclosures, group composition, sex and an interaction between group composition and the ability to view cheetahs in adjacent enclosures, all significantly influenced the prevalence of exploratory behavior in captive cheetahs. The presence of raised areas and an increasing number of movements between enclosures significantly increased the probability of observing exploratory behaviour, while this probability was significantly decreased for female cheetahs, when cheetahs were able to view conspecifics in adjacent enclosures, and were maintained in groups. A number of recommendations are discussed in relation to promoting exploratory behavior in captive cheetahs.

    Full Text Available In Bangladesh, the burden of diarrheal diseases is significant among children <5 years old. The objective of this study is to capture the prevalence of and health care–seeking behavior for childhood diarrheal diseases (CDDs and to identify the factors associated with CDDs at a population level in Bangladesh. We use a logistic regression approach to model careseeking based on individual characteristics. The overall diarrhea prevalence among children <5 years old was found to be 5.71%. Some factors found to significantly influence the health care–seeking pattern were age and sex of the children, nutritional score, age and education of mothers, wealth index, and access to electronic media. The health care service could be improved through working in partnership with public facilities, private health care practitioners, and community-based organizations, so that all strata of the population get equitable access in cases of childhood diarrhoea.

    Background Little population-based data exist outside the United States on the epidemiology of binge eating disorder (BED). Cross-national data on BED are presented and compared to bulimia nervosa (BN) based on the WHO World Mental Health Surveys. Methods Community surveys with 24,124 respondents (ages 18+) across 14 mostly upper-middle and high income countries assessed lifetime and 12-month DSM-IV mental disorders with the WHO Composite International Diagnostic Interview. Physical disorders were assessed with a chronic conditions checklist. Results Country-specific lifetime prevalence estimates are consistently (median; inter-quartile range) higher for BED (1.4%;0.8–1.9%) than BN (0.8%;0.4–1.0%). Median age-of-onset is in the late teens to early 20s for both disorders but slightly younger for BN. Persistence is slightly higher for BN (6.5 years; 2.2–15.4) than BED (4.3 years; 1.0–11.7). Lifetime risk of both disorders is elevated for women and recent cohorts. Retrospective reports suggest that comorbid anxiety, mood, and disruptive behavior disorders predict subsequent onset of BN somewhat more strongly than BED and that BN predicts subsequent comorbid psychiatric disorders somewhat more strongly than does BED. Significant comorbidities with physical conditions are due almost entirely to BN and BED predicting subsequent onset of these conditions, again with BN somewhat stronger than BED. Role impairments are similar for BN and BED. Fewer than half of lifetime BN or BED cases receive treatment. Conclusions BED represents a public health problem at least equal to BN. Low treatment rates highlight the clinical importance of questioning patients about eating problems even when not included among presenting complaints. PMID:23290497

    Full Text Available Objective:To identify the prevalence of internalizing and externalizing behavior problems among preschoolers from the city of Salvador, state of Bahia, Brazil, and their associations with maternal mental health and family characteristics.Methods:This was a cross-sectional study of 349 children aged 49 to 72 months, randomly selected from 20,000 households representing the range of socioeconomic and environmental conditions in Salvador. In 1999, we assessed sociodemographic variables and family environment characteristics. In 2001, we used the Child Behavior Checklist to measure and describe the frequencies of behavior problems. We conducted bivariate and multivariate analysis to estimate associations between family and maternal factors and prevalence of behavior problems.Results:The overall prevalence of behavior problems was 23.5%. The prevalence of internalizing problems was 9.7%, and that of externalizing problems, 25.2%. Behavior problems were associated with several maternal mental health variables, namely: presence of at least one psychiatric diagnosis (odds radio [OR] 3.01, 95%CI 1.75-5.18, anxiety disorder (OR 2.06, 95%CI 1.20-3.46, affective disorder (OR 2.10, 95%CI 1.21-3.65, and mental health disorders due to use of psychoactive substances (OR 2.31, 95%CI 1.18-4.55.Conclusion:The observed prevalence of child behavior problems fell within the range reported in previous studies. Maternal mental health is an important risk factor for behavior problems in preschool-aged children.

    Full Text Available Abstract Background Oral health status in India is traditionally evaluated using clinical indices. There is growing interest to know how subjective measures relate to outcomes of oral health. The aims of the study were to assess the prevalence and correlates of self-reported state of teeth in 12-year-old schoolchildren in Kerala, India. Methods Cross-sectional survey data were used. The sample consisted of 838 12-year-old schoolchildren. Data was collected using clinical examination and questionnaire. The clinical oral health status was recorded using Decayed, Missing and Filled Teeth (DMFT and Oral Hygiene Index – Simplified (OHI-S. The questionnaire included questions on sociodemographics, self reports of behaviour, knowledge and oral problems and a single-item measuring self-reported state and satisfaction with appearance of teeth. The Kappa values for test-retest of the questionnaire ranged from 0.55 to 0.97. Results Twenty-three per cent of the schoolchildren reported the state of teeth as bad. Multivariate logistic regression showed significant associations between schoolchildren who reported to have bad teeth and poor school performance (Odds Ratio (OR = 2.5, having bad breath (OR = 2.4, food impaction (OR = 1.7 dental visits (OR = 1.6, being dissatisfied with appearance of teeth (OR = 4.2 and caries experience (OR = 1.7. The explained variance was highest when the variables dental visits, bleeding gums, bad breath, food impaction and satisfaction with appearance were introduced into the model (19%. Conclusion A quarter of 12-year-olds reported having bad teeth. The self-reported bad state of teeth was associated with poor school performance, having bad breath and food impaction, having visited a dentist, being dissatisfied with teeth appearance and having caries experience. Information from self-reports of children might help in planning effective strategies to promote oral health.

    We surveyed 122 trans men using a hybrid sampling method that included randomly selected physical and online venues and peer referral to measure HIV prevalence and risk behaviors. HIV prevalence was 0% (one-sided 97.5% confidence interval 0-3.3%). Of 366 partnerships described, 44.8% were with cisgender women, 23.8% with cisgender men, 20.8% with trans men, and 10.7% with trans women. Condomless receptive anal and front hole/vaginal sex averaged one to three episodes per six months. HIV prevalence in trans men is likely closer to heterosexual cisgender men and women in San Francisco than trans women or MSM. Prevention prioritizing trans women and MSM, coupled with individualized and relevant sexual health education for trans men with partners from these populations, may best address the HIV prevention needs of trans men. Systematic collection of transgender status in Census and health data is needed to understand other health disparities among trans men.

    Management of damaging invasive plants is often undertaken by multiple decision makers, each managing only a small part of the invader's population. As weeds can move between properties and re-infest eradicated sites from unmanaged sources, the dynamics of multiple decision makers plays a significant role in weed prevalence and invasion risk at the landscape scale. We used a spatially explicit agent-based simulation to determine how individual agent behavior, in concert with weed population ecology, determined weed prevalence. We compared two invasive grass species that differ in ecology, control methods, and costs: Nassella trichotoma (serrated tussock) and Eragrostis curvula (African love grass). The way decision makers reacted to the benefit of management had a large effect on the extent of a weed. If benefits of weed control outweighed the costs, and either net benefit was very large or all agents were very sensitive to net benefits, then agents tended to act synchronously, reducing the pool of infested agents available to spread the weed. As N. trichotoma was more damaging than E. curvula and had more effective control methods, agents chose to manage it more often, which resulted in lower prevalence of N. trichotoma. A relatively low number of agents who were intrinsically less motivated to control weeds led to increased prevalence of both species. This was particularly apparent when long-distance dispersal meant each infested agent increased the invasion risk for a large portion of the landscape. In this case, a small proportion of land mangers reluctant to control, regardless of costs and benefits, could lead to the whole landscape being infested, even when local control stopped new infestations. Social pressure was important, but only if it was independent of weed prevalence, suggesting that early access to information, and incentives to act on that information, may be crucial in stopping a weed from infesting large areas. The response of our model to both

    Body-focused repetitive behaviors such as skin picking have gained recent attention in the psychiatric literature. Prevalence of skin picking has not been well researched and is difficult to estimate; however, consequences of such behaviors can include severe medical complications and impaired social and occupational functioning. Given this, this study examined: (1) the prevalence and severity of skin picking in a nonclinical community sample, and (2) associations between skin picking and other measures of psychological functioning. Three hundred and fifty-four participants completed measures of psychological functioning and skin picking frequency and severity. A total of 62.7% endorsed some form of skin picking and 5.4% reported clinical levels of skin picking and associated distress/impact. Direct associations were found between skin picking and depressive, anxiety, and obsessive-compulsive symptoms, which may support the emotional regulation model of pathological skin picking. To establish proper diagnostic classification of pathological skin picking and optimize treatment planning and outcome, further investigation of functional relationships between skin picking and affective distress is needed.

    The mental health needs of patients who are coinfected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) are increasingly addressed in medical settings. This study aimed at examining the prevalence and severity of emotional distress in a sample of HIV/HCV coinfected and HIV mono-infected patients and to examine their sociodemographic, clinical, and psychosocial correlates. The Brief Symptom Inventory and the quality of life instrument WHOQOL-HIV-Bref were administered to a sample of 248 HIV/HCV coinfected patients and 482 HIV mono-infected patients. Thirty-nine (15.9%) HIV/HCV coinfected patients and 55 (11.6%) HIV mono-infected patients reported a T-score ≥ 63 for global severity index (GSI), indicative of a need for further psychological evaluation. Coinfected patients reported significantly higher scores on eight of nine dimensions of psychopathology. The larger differences were found on somatization, hostility, paranoid ideation, anxiety, and the GSI. Among HIV/HCV patients, non-highly active antiretroviral therapy (β = -0.19, p < 0.01) and lower scores for independence (β = -0.24, p < 0.01) and spiritual (β = -0.31, p < 0.001) dimensions were significantly associated with higher emotional distress and accounted for 47.2% of the total variance. Among HIV mono-infected patients, being diagnosed for a longer time (β = 0.12, p < 0.05) and having lower scores on physical (β = -0.23, p < 0.001), social relationships (β = -0.11, p < 0.05), environmental (β = -0.17, p < 0.01), and spiritual (β = -0.21, p < 0.001) dimensions explained 39.4% of the variance of emotional distress. The findings suggest that coinfection with HCV may have an adverse effect on mental health and underscore the interplay of sociodemographic, clinical, and psychosocial variables on emotional distress. Additionally, these data reinforce the need for tailored interventions to improve the overall well-being of both HIV and HIV/HCV patients.

    Recent literature reviews show that bullying perpetration and victimization are major public health concerns for typically developing (TD) youth. Nevertheless, the magnitude of this phenomenon among youth with intellectual disabilities (ID) remains unclear. Therefore, the purpose of this review is to provide a synthesis of the empirical studies examining the prevalence and correlates of bullying perpetration and victimization among youth with ID. A systematic literature search was performed and 11 studies met the inclusion criteria. The findings from these studies showed weighted mean prevalence rates of general bullying perpetration, bullying victimization and both of 15.1%, 36.3%, and 25.2%, respectively. Weighted mean prevalence rates of bullying perpetration and victimization differed according to the characteristics of the studies (e.g., assessment context, school setting, information source, type of measures, time frame). Additionally, high weighted mean prevalence rates of physical (33.3%), verbal (50.2%), relational (37.4%), and cyber (38.3%) victimization were found among youth with ID. When youth with ID were compared to youth with other disabilities or TD peers, no clear differences were found. Finally, the present review shows that correlates of bullying perpetration and victimization in this population remain understudied.

    Correlated suits of behaviors (behavioral syndrome) are commonly observed in both inter- and intraspecific studies. In order to understand the genetic basis of such a correlation between species, we compared ten behaviors classified into five categories (acclimation, feeding, normal swimming, reaction to a novel object and activity in a novel environment) between two pufferfish species, Takifugu rubripes and T. niphobles. The two species showed consistent differences in nine behaviors with a significant correlation among behaviors. Quantitative trait locus (QTL) analysis using second generation hybrids revealed that different sets of small effect QTL are associated with the observed interspecific behavioral disparity. This indicates that correlations in temperament traits between them are governed by many genes with small effects, and each behavior has been selected to form particular combination patterns. One of the QTL showing small pleiotropic effect includes the Drd4 gene known for its association with behavioral traits in some animal taxa including mammals.

    Correlation between length scales in the field of magnetism has long been a topic of intensive study. The long-term desire is simple: to determine one theory that completely describes the magnetic behavior of matter from an individual atomic particle all the way up to large masses of material. One key piece to this puzzle is connecting the behavior of a material's domains on the nanometer scale with the magnetic properties of an entire large sample or device on the centimeter scale. In the first case study involving the FeSiAl thin films, contrast and spacing of domain patterns are clearly related to microstructure and stress. Case study 2 most clearly demonstrates localized, incoherent domain wall motion switching with field applied along an easy axis for a square hysteresis loop. In case study 3, axis-specific images of the complex Gd-Si-Ge material clearly show the influence of uniaxial anisotropy. Case study 4, the only study with the sole intent of creating domain structures for imaging, also demonstrated in fairly simple terms the effects of increasing stress on domain patterns. In case study 5, it was proven that the width of magnetoresistance loops could be quantitatively predicted using only MFM. When all of the case studies are considered together, a dominating factor seems to be that of anisotropy, both magneticrostaylline and stress induced. Any quantitative bulk measurements heavily reliant on K coefficients, such as the saturation fields for the FeSiAl films, Hc in cases 1, 3, and 5, and the uniaxial character of the Gd5(Si2Ge2), transferred to and from the domain scale quite well. In-situ measurements of domain rotation and switching, could also be strongly correlated with bulk magnetic properties, including coercivity, Ms, and hysteresis loop shape. In most cases, the qualitative nature of the domain structures, when properly considered, matched quite well to what might have been expected

    OBJECTIVE Despite growing interest in adult attention-deficit/hyperactivity disorder (ADHD), little is known about prevalence or correlates. METHODS A screen for adult ADHD was included in a probability sub-sample (n = 3199) of 18–44 year old respondents in the National Comorbidity Survey Replication (NCS-R), a nationally representative household survey that used a lay-administered diagnostic interview to assess a wide range of DSM-IV disorders. Blinded clinical follow-up interviews of adult ADHD were carried out with 154 NCS-R respondents, over-sampling those with a positive screen. Multiple imputation (MI) was used to estimate prevalence and correlates of clinician-assessed adult ADHD. RESULTS Estimated prevalence of current adult ADHD is 4.4%. Significant correlates include being male, previously married, unemployed, and Non-Hispanic White. Adult ADHD is highly comorbid with many other NCS-R/DSM-IV disorders and is associated with substantial role impairment. The majority of cases are untreated, although many obtain treatment for other comorbid mental and substance disorders. CONCLUSIONS Efforts are needed to increase the detection and treatment of adult ADHD. Research is needed to determine whether effective treatment would reduce the onset, persistence, and severity of disorders that co-occur with adult ADHD. PMID:16585449

    Full Text Available Background: Premarital sex is often associated with high risk sexual behavior such as early age of initiation, multiple partners and inconsistent condom use. Evidence shows that such sexual behavior pre-disposes to sexually transmitted diseases including HIV. Objectives: This paper tried to investigate the correlates of premarital sexual behavior among male and female business process outsourcing (BPO employees to highlight the gender differences that exist in relation to it. Materials and Methods: Data were collected from 526 unmarried BPO employees during behavioral surveillance survey in Chennai, in the year 2009. Results: The results showed that about one-third of respondents (males - 39.6%, females - 26.1% had experienced premarital sex. Men reported having had their first sexual intercourse at 12 years and women at 16 years of age. While the prevalence of premarital sex was found to be high, the percentage using a condom during last sex was also high, especially, among the female employees (82.4%. Logistic regression showed that monthly individual income, work in shifts, migration, peer influence and friends with previous sexual experience were significant predictors of premarital sex among the male BPO employees. Visit to night clubs was significantly associated with a higher prevalence of premarital sex among the female employees. Conclusions: The study concludes that there is a significant gender dimension in the premarital sexual behavior among the BPO employees and that even as the sexual behavior of the young people is transitioning; their ability to negotiate safe sex behavior is also increasing. It is recommended to enhance efforts to advocate safe sex behavior among young adults employed in the BPO industry.

    Full Text Available Acute respiratory tract infections (ARTIs are associated with significant morbidity and mortality worldwide, especially in children under the age of 5 years. Almost 2 million children die from ARTIs each year, and most of them are from developing countries. The prevalence and correlation of pathogens in ARTIs are poorly understood, but are critical for improving case prevention, treatment, and management. In this study, we investigated the prevalence and correlation of infectious agents in children with ARTIs. A total of 39,756 children with one or more symptoms, including fever, cough, sore throat, tonsillitis, pharyngitis, herpangina, pneumonia, and bronchiolitis, were enrolled in the study. All patients were hospitalized in Wuhan Children's Hospital between October 1, 2010 and September 30, 2012, and were evaluated for infectious agents. Pathogens, including Mycoplasma pneumoniae, influenza A virus, influenza B virus, adenoviruses, respiratory syncytial virus, parainfluenza virus, Legionella pneumophila, Chlamydophila pneumoniae, and Coxiella burnetii, were screened simultaneously in patient blood samples using anti-pathogen IgM tests. Regression analysis was used to reveal correlations among the pathogens. Our results showed that one or more pathogens were identified in 10,206 patients, and that Mycoplasma pneumoniae, adenoviruses, and influenza B virus were the leading infectious agents. Mixed-infections of pathogens were detected in 2,391 cases, with Mycoplasma pneumoniae as the most frequent pathogen. The most common agents in the co-infections were Mycoplasma pneumoniae and influenza B virus. Regression analysis revealed a linear correlation between the proportion of mixed infections and the incidence of multi-pathogen infections. The prevalence of infectious agents in children with ARTIs was determined. Equations were established to estimate multiple infections by single-pathogen detection. This revealed a linear correlation for

    Full Text Available The prevalence of diabetes is increasing worldwide. The objective of this study is to estimate the prevalence of self-reported diabetes in Brazilian adults and to describe its population correlates as well as the clinical characteristics of the reported cases.We analyzed basic and supplementary data of 54.144 subjects participating in VIGITEL 2011 (Surveillance System for Risk and Protective Factors for Chronic Diseases, a telephone survey based on a probabilistic sample of subjects ≥ 18 years old residing in Brazilian state capitals and the Federal District. Estimates reported are weighted so as to represent the surveyed population.The prevalence of self-reported diabetes was 6.3% (95% CI 5.9-6.7, increasing markedly with age and nutritional status, and decreasing with level of education. Prevalence was higher among those self-declaring their race/color as black. Most cases (90% reported the diagnosis being made at 35 years or older. The vast majority (99.8% of self-reported cases informed having previously performed at least one glucose test, and 76% of those not reporting diabetes also informed having previously performed glucose testing. Most cases (92.6% reported following some form of diabetes treatment, 79% taking medication.The estimated prevalence of known diabetes found, 6.3%, is consistent with estimates given by international summaries. The additional data collected in VIGITEL 2011 regarding previous glucose testing and current treatment support the use of telephone-based information to monitor the prevalence of known diabetes in Brazilian capitals.

    Stomach cancer is one of the most common cancers in Korea. The aim of this study was to identify the association between the prevalence of cancer, particularly stomach cancer, and the amount of 24-hr urine sodium excretion estimated from spot urine specimens. The study included 19,083 subjects who took part in the Korean National Health and Nutritional Examination Survey between 2009 and 2011. The total amount of urine sodium excreted in a 24-hr period was estimated by using two equations based on the values for spot urine sodium and creatinine. In subjects who had an estimated 24-hr urine sodium excretion of more than two standard deviations above the mean (group 2), the prevalence of stomach cancer was higher than in subjects with lower 24-hr sodium excretion (group 1). By using the Tanaka equation to estimate it, the prevalence of stomach cancer was 0.6% (114/18,331) in group 1, whereas it was 1.6% (9/568) in group 2 (P=0.006). By using the Korean equation, the prevalence was 0.6% (115/18,392) in group 1, and 1.6% in group 2 (8/507) (P=0.010). By using the Tanaka equation, breast cancer in women is more prevalent in group 2 (1.9%, 6/324) than group 1 (0.8%, 78/9,985, P=0.039). Higher salt intake, as defined by the estimated amount of 24-hr urine sodium excretion, is positively correlated with a higher prevalence of stomach or breast cancer in the Korean population.

    Study Objectives: To estimate the prevalence of, and to identify correlates of clinically significant sleep problems in adult Israeli citizens exposed to chronic terrorism and war trauma or threat thereof. Methods: A population-based, cross-sectional study of 1001 adult Israeli citizens interviewed by phone between July 15 and August 26, 2008. The phone survey was conducted in Hebrew and assessed demographics, trauma/stressor exposure, probable posttraumatic stress disorder (PTSD), probable depression, and sleep problems. Probable PTSD and depression were assessed with the PTSD Symptom Scale (PSS) and Patient Health Questionnaire (PHQ-9), respectively, following DSM-IV diagnostic criteria. Sleep problems in the past month were assessed with the Pittsburgh Sleep Quality Index (PSQI), on which a global composite score ≥ 6 indicates a clinical-level sleep problem. Results: Prevalence of probable PTSD and depression was 5.5% and 5.8%, respectively. Prevalence of clinically significant sleep problems was 37.4% overall, but was significantly higher for probable PTSD (81.8%) and probable depression (79.3%) subgroups. Independent correlates of poor sleep included being female, older, less educated, experiencing major life stressors, and experiencing psychosocial resource loss. Psychosocial resource loss due to terrorist attacks emerged as the strongest potentially modifiable risk factor for sleep problems. Conclusions: Sleep problems are common among Israeli adults living under chronic traumatic threat and trauma exposure.

    The present study reports past-year prevalence of and comorbidities associated with the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) disorders in 1645 children aged 6 to 12 years in Seoul, Korea. The diagnosis was based on the parental version of the Diagnostic Interview Schedule for Children (DISC-IV). Our participants completed the Children's Depression Inventory (CDI). The estimated prevalence of any full-syndrome and subthreshold DSM-IV disorders were 16.2% and 28.1%, respectively. The most prevalent disorders were specific phobia (9.6%), attention-deficit hyperactivity disorder (ADHD; 5.9%), and oppositional defiant disorder (ODD; 4.9%). The estimated prevalence of depressive disorder was 0.1% according to the DISC-IV and1.9% according to the CDI. ADHD, ODD, and anxiety disorders were highly comorbid. Our study highlights the importance of obtaining children's self-report data in addition to the parents' interview, particularly for depression, and the importance of early detection of subthreshold conditions and considering comorbid diagnoses.

    Full Text Available Background. The aim of this study is to evaluate whether geographic variations in the prevalence of late-stage chronic kidney disease (CKD exist and are associated with incidence rates of renal cell carcinoma (RCC, upper tract urothelial carcinoma (UTUC, or lower tract urothelial carcinoma (LTUC. Methods. Prevalence rates of late-stage CKD for 366 townships (n>30 in Taiwan were calculated for 1,518,241 and 1,645,151 subjects aged 40 years or older in years 2010 and 2009, respectively. Late-stage CKD prevalence in year 2010 was used as a training set and its age-adjusted standardized morbidity rates (ASMR were divided into three groups as defined <1.76%, 1.76% ≤ ASMR < 2.64%, and ≥2.64%, respectively. Year 2009, defined as the validation set, was used to validate the results. Results. The ASMR of late-stage CKD in years 2010 and 2009 were 1.76%, and 2.09%, respectively. Geographic variations were observed, with notably higher rates of disease in areas of the central, southwestern mountainside, and southeastern seaboard. There were no significant differences among different combined risk groups of RCC, UTUC, and LTUC incidence. Conclusion. The substantial geographic variations in the prevalence of late-stage CKD exist, but are not correlated with RCC, UTUC, or LTUC incidence.

    2005-03-01

    Full Text Available Introduction The health benefits of regular cardiovascular exercise are well-known. Such exercise, however, has traditionally been defined as vigorous physical activity, such as jogging, swimming, or aerobic dance. Exercise of moderate intensity also promotes health, and many U.S. adults may be experiencing the health benefits of exercise through lifestyle activities of moderate intensity, such as yard work, housework, or walking for transportation. Until recently, public health surveillance systems have not included assessments of this type of physical activity, focusing on exercise of vigorous intensity. We used an enhanced surveillance tool to describe the prevalence and amount of both moderate-intensity and vigorous-intensity physical activity among U.S. adults. Methods We analyzed data from the 2001 Behavioral Risk Factor Surveillance System, a state-based, random-digit–dialed telephone survey administered to U.S. adults aged 18 years and older (n = 82,834 men and 120,286 women. Physical activity behavior was assessed using questions designed to quantify the frequency of participation in moderate- or vigorous-intensity physical activities performed during leisure time or for household chores and transportation. Results Overall, 45% of adults (48% of men and 43% of women were active at recommended levels during nonworking hours (at least 30 minutes five or more days per week in moderate-intensity activities, equivalent to brisk walking, or at least 20 minutes three or more days per week in vigorous activities, equivalent to running, heavy yard work, or aerobic dance. Less than 16% of adults (15% of men and 17% of women reported no moderate or vigorous activity in a usual week. Conclusion Integrating surveillance of lifestyle activities into national systems is possible, and doing so may provide a more accurate representation of the prevalence of recommended levels of physical activity. These results, however, suggest that the majority of U

    To date, there are no studies from El Salvador among people with HIV to inform prevention programs. We conducted a study in El Salvador in 2008 among people with HIV using audio computer-assisted interviews on risk behaviors and access to health care. Blood was tested for syphilis and herpes simplex type 2 (HSV-2). Active syphilis was defined as RPR titer ≥1:8. Genital specimens were tested for other sexually transmitted infections (STI) by PCR. We evaluated factors associated with unprotected sex with last stable partner of HIV-negative or unknown status among those reporting a stable partner. A total of 811 HIV-positive individuals participated: 413 men and 398 women. Prevalence of Chlamydia and gonorrhea was low (≤1%), while prevalence of other STI was high: Mycoplasma genitalium (14%), syphilis (15% seropositivity, active syphilis 3%) and HSV-2 (85%). In multivariate analysis, disclosing HIV status to partner (OR 0.2, 95% CI: 0.1-0.3, p<0.001), participation in HIV support groups (OR 0.3, 95% CI: 0.1-0.8, p=0.01), easy access to condoms (OR 0.4, 95% CI: 0.2-0.9, p=0.04) were protective factors for unprotected sex. Reporting a casual partner in the last 12 months (OR 3.6, 95% CI: 1.5-8.5, p=0.004). and having an STI (OR 2.6, 95% CI:1.3-5.5, p=0.02) were associated with an increased odds of unprotected sex. Prevention interventions among HIV-positives in El Salvador should focus on increasing condom access, promoting HIV disclosure and couples testing and reducing the number of partners. The positive role of support groups should be used to enhance behavioral change.

    Although several studies have detected differences in clinical features among specific phobias, there is a shortage of detailed national data on the on the DSM-IV SP subtypes, particularly in the Asian population. To examine the prevalence, demographic and other correlates, and co-morbidities of DSM-IV SP subtypes in a nationwide sample of Korean adults. We recruited 6510 participants aged 18-64 years for this study. Lay interviewers used the Composite International Diagnostic Interview to assess participants. We analyzed socio-demographics, health-related correlates and frequencies of comorbid mental disorders among participants with SP and each subtypes compared to unaffected adults. The prevalence of lifetime DSM-IV SP was 3.8%, and animal phobias were the most prevalent type of SP. Blood-injection-injury phobia was negatively associated with education, whereas situational phobia was positively associated with education. The strongest mental disorder comorbidity was associated with situational phobia; there is a higher probability of comorbid mood (OR=5.73, 95% CI=2.09-15.73), anxiety (OR=7.54, 95% CI=2.34-24.28), and somatoform disorders (OR=7.61, 95% CI=1.64-35.22) with this subtype. Blood-injection-injury phobia was highly associated with alcohol dependence (OR=9.02, 95% CI=3.54-23.02). Specific phobias are heterogeneous with respect to socio-demographic characteristics and comorbidity pattern. Implications of the usefulness of current subtype categories should continue to be investigated.

    Understanding correlations in complex systems is crucial in the face of turbulence, such as the ongoing financial crisis. However, in complex systems, such as financial systems, correlations are not constant but instead vary in time. Here we address the question of quantifying state-dependent correlations in stock markets. Reliable estimates of correlations are absolutely necessary to protect a portfolio. We analyze 72 years of daily closing prices of the 30 stocks forming the Dow Jones Industrial Average (DJIA). We find the striking result that the average correlation among these stocks scales linearly with market stress reflected by normalized DJIA index returns on various time scales. Consequently, the diversification effect which should protect a portfolio melts away in times of market losses, just when it would most urgently be needed. Our empirical analysis is consistent with the interesting possibility that one could anticipate diversification breakdowns, guiding the design of protected portfolios.

    Knowledge of sexual partners' HIV infection can reduce risky sexual behaviors. Yet, there are no published studies to-date examining prevalence and characteristics associated with knowledge among African-American women living in high poverty communities disproportionately affected by HIV. Using the HIV Prevention Trial Network's (HPTN) 064 Study data, multivariable logistic regression was used to examine individual, partner, and partnership-level determinants of women's knowledge (n = 1,768 women). Results showed that women's demographic characteristics alone did not account for the variation in serostatus awareness. Rather, lower knowledge of partner serostatus was associated with having two or more sex partners (OR = 0.49, 95 % CI 0.37-0.65), food insecurity (OR = 0.68, 95 % CI 0.49-0.94), partner age >35 years (OR = 0.68, 95 % CI 0.49-0.94), and partner concurrency (OR = 0.63, 95 % CI 0.49-0.83). Access to financial support (OR = 1.42, 95 % CI 1.05-1.92) and coresidence (OR = 1.43, 95 % CI 1.05-1.95) were associated with higher knowledge of partner serostatus. HIV prevention efforts addressing African-American women's vulnerabilities should employ integrated behavioral, economic, and empowerment approaches.

    Full Text Available Abstract Background Few data are available in Afghanistan to shape national military force health practices, particularly with regard to sexually-transmitted infections (STIs. We measured prevalence and correlates of HIV, syphilis, herpes simplex 2 virus (HSV-2, and hepatitis C virus (HCV among Afghan National Army (ANA recruits. Methods A cross-sectional sample of male ANA recruits aged 18–35 years were randomly selected at the Kabul Military Training Center between February 2010 and January 2011. Participants completed an interviewer-administered questionnaire and serum-based rapid testing for syphilis and hepatitis C virus antibody on-site; HIV and HSV-2 screening, and confirmatory testing were performed off-site. Prevalence of each infection was calculated and logistic regression analysis performed to identify correlates. Results Of 5313 recruits approached, 4750 consented to participation. Participants had a mean age of 21.8 years (SD±3.8, 65.5% had lived outside Afghanistan, and 44.3% had no formal education. Few reported prior marijuana (16.3%, alcohol (5.3%, or opiate (3.4% use. Of sexually active recruits (58.7%, N = 2786, 21.3% reported paying women for sex and 21.3% reported sex with males. Prevalence of HIV (0.063%, 95% CI: 0.013- 0.19, syphilis (0.65%, 95% CI: 0.44 – 0.93, and HCV (0.82%, 95% CI: 0.58 – 1.12 were quite low. Prevalence of HSV-2 was 3.03% (95% CI: 2.56 - 3.57, which was independently associated with age (Adjusted Odds Ratio (AOR = 1.04, 95% CI: 1.00 - 1.09 and having a television (socioeconomic marker (AOR = 1.46, 95% CI: 1.03 – 2.05. Conclusion Though prevalence of HIV, HCV, syphilis, and HSV-2 was low, sexual risk behaviors and intoxicant use were present among a substantial minority, indicating need for prevention programming. Formative work is needed to determine a culturally appropriate approach for prevention programming to reduce STI risk among Afghan National Army troops.

    Full Text Available Alzheimer’s disease (AD, the most prevalent dementia, is characterized not only by cognitive but also behavioral changes that pose the heaviest burden to caregivers. Differences in the clinical picture depending on the time of disease onset have been observed. We correlated cognitive and behavioral deficits in patients with presenile- and senile-onset AD to explore the differences. We tested 60 AD patients, 19 male and 41 female, mean age 65.2 years with the Dementia Behavior Disturbance Scale (DBD and a standard neuropsychological battery. The patients were divided according to their DBD score into two groups: group I - score 0-2 (n=24; 40%, group II - score 3≥ (n=36; 60%, comparable in disease duration and neurological findings. The cognitive scores were significantly higher in the group with less behavioral changes than in the group with more behavioral changes: Mini Mental State Examination score (p=0.0015, serial subtraction (p=0.0009, block design (p=0.0049, copy of complex figure (p=0.0125, complex visual organization (p=0.0099, divided attention, visual memory and speech comprehension. A significantly higher frequency of behavioral disturbances was registered in patients with senile onset than in the presenile-onset group (p<0.005. There were no sex differences. Our data show a correlation between cognitive decline and behavioral changes in late onset AD patients, indicating that more behavioral disturbances were associated with a more severe degree of cognitive decline, especially in non-verbal functions and attention deficits, compared to early onset patients.

    Full Text Available Introduction It is important to understand the characteristics and vulnerabilities of people who have hepatitis C because this disease is currently an important public health problem. The objective of this study was to estimate the prevalence of depressive symptoms and harmful alcohol use in patients with hepatitis C and to study the association between these outcomes and demographic, psychosocial and clinical variables. Methods This cross-sectional, descriptive and analytical study involved 82 hepatitis C patients who were being treated with pegylated interferon and ribavirin at a public university hospital. The primary assessments used in the study were the Alcohol Use Disorders Identification Test and the Beck Depression Inventory. Bivariate analyses were followed by logistic regression. Results The prevalence of depressive symptoms was 30.5% (n=25, and that of harmful alcohol use was 34.2% (n=28. Logistic regression analysis showed that individuals who were dissatisfied with their social support (OR=4.41; CI=1.00-19.33 and were unemployed (OR=6.31; CI=1.44-27.70 were at a higher risk for depressive symptoms, whereas harmful alcohol use was associated with the male sex (OR=6.78; CI=1.38-33.19 and the use of illicit substances (OR=7.42; CI=1.12-49.00. Conclusions High prevalence rates of depressive symptoms and harmful alcohol use were verified, indicating vulnerabilities that must be properly monitored and treated to reduce emotional suffering in this population.

    Dysmenorrhea is a common menstrual disorder experienced by adolescents, and its major symptoms, including pain, adversely affect daily life and school performance. However, little epidemiologic evidence on dysmenorrhea in Japanese adolescents exists. This cross-sectional study aimed to determine the prevalence of and identify factors associated with dysmenorrhea in Japanese female junior high school students. Among 1,167 girls aged between 12 and 15 years, 1,018 participants completed a questionnaire that solicited information on age at menarche, menstruation, and lifestyle, as well as demographic characteristics. Dysmenorrhea was defined based on menstrual pain using a Visual Analog Scale (VAS), with moderate or severe (moderate-severe) dysmenorrhea, which adversely affects daily life, defined as VAS ≥ 4, and severe dysmenorrhea defined as VAS ≥ 7. The prevalence of moderate-severe dysmenorrhea was 476/1,018 (46.8%), and that of severe dysmenorrhea was 180/1,018 (17.7%). Higher chronological and gynecological ages (years after menarche) were significantly associated with a higher prevalence of dysmenorrhea regardless of severity (P for trend students.

    Full Text Available Adolescent sexuality is a relevant public health issue, as it affects risk to contract HIV and other sexually transmitted infections. The assessment of prevalence of sexual intercourse among adolescents may guide policies and programmes aimed at reducing the transmission of sexually transmitted infections among this age group. Using data from the Thailand Global School-Based Student Health Survey (GSHS 2008, we assessed the prevalence of sexual intercourse in the last 12 months and its associated factors among adolescents (=2758. Overall the prevalence of sexual intercourse in the past 12 months was 11.0% (14.6% males and 7.6% females. Variables positively associated with the outcome in multivariable analysis were male gender (OR=1.66; 95% CI 1.14–242, older age, ≥15 years (OR=2.60, 1.80–3.74, current alcohol use (OR=2.22, 1.46–3.36, psychosocial distress (OR=2.11, 1.44–3.09 and among females current smoking (OR=5.47, 1.62–18.48, lifetime drug use (AOR=4.35, 1.04–18.3 and lack of parental or guardian bonding (AOR=0.51, 0.27–0.97. Efforts to control unhealthy lifestyles (substance use and psychosocial distress may impact on adolescents' sexual activity.

    To compare the prevalence of pulp calcification with that of carotid calcification using digital panoramic dental radiographs. Digital panoramic radiographs of patients at a dental oncology clinic were included if (1) the carotid artery bifurcation region was visible bilaterally and (2) the patient had non-restored or minimally restored molars and/or canines. An endodontist evaluated the images for pulpal calcifications in the selected teeth. An oral and maxillofacial radiologist independently evaluated the same images for calcifications in the carotid bifurcation region. Odds-ratio and Pearson {chi}{sup 2} were used for data analysis. Presence of pulpal calcification was also evaluated as a screening test for the presence of carotid calcification. A total of 247 panoramic radiographs were evaluated. 32% (n=80) had pulpal calcifications and 25% (n=61) had carotid calcifications with 12% (n=29) having both carotid and pulp calcifications. A significantly higher prevalence of both pulp and carotid calcification was found in subjects older than age 60 years compared to younger age groups. Accuracy of pulpal calcification in screening for carotid calcification was 66.4%. Both pulp and carotid calcifications were more prevalent in older individuals. The presence of pulp calcification was not a strong predictor for the presence of carotid calcification. (orig.)

    The purpose of this study was to examine the phenotypic, genetic, and environmental relationships between multiple dimensions of Type A behavior and personality. Adult twins (N=247 pairs) completed a self-report personality measure and a work style questionnaire that measured six facets of Type A behavior: impatience, anger, work involvement, time urgency, job dissatisfaction, and competitiveness. Univariate results suggest that only the job dissatisfaction facet of Type A behavior was explained by non-genetic (environmental) factors. Multivariate results suggest that all of the genetically determined facets of Type A behavior show some correspondence with at least one of the personality factors found in the study, suggesting that some of the phenotypic (observed) relationships could be due to common genetic factors.

    Abnormal behaviors in captive animals are generally defined as behaviors that are atypical for the species and are often considered to be indicators of poor welfare. Although some abnormal behaviors have been empirically linked to conditions related to elevated stress and compromised welfare in primates, others have little or no evidence on which to base such a relationship. The objective of this study was to investigate a recent claim that abnormal behavior is endemic in the captive population by surveying a broad sample of chimpanzees (Pan troglodytes), while also considering factors associated with the origins of these behaviors. We surveyed animal care staff from 26 accredited zoos to assess the prevalence of abnormal behavior in a large sample of chimpanzees in the United States for which we had information on origin and rearing history. Our results demonstrated that 64% of this sample was reported to engage in some form of abnormal behavior in the past two years and 48% of chimpanzees engaged in abnormal behavior other than coprophagy. Logistic regression models were used to analyze the historical variables that best predicted the occurrence of all abnormal behavior, any abnormal behavior that was not coprophagy, and coprophagy. Rearing had opposing effects on the occurrence of coprophagy and the other abnormal behaviors such that mother-reared individuals were more likely to perform coprophagy, whereas non-mother-reared individuals were more likely to perform other abnormal behaviors. These results support the assertion that coprophagy may be classified separately when assessing abnormal behavior and the welfare of captive chimpanzees. This robust evaluation of the prevalence of abnormal behavior in our sample from the U.S. zoo population also demonstrates the importance of considering the contribution of historical variables to present behavior, in order to better understand the causes of these behaviors and any potential relationship to psychological

    Full Text Available There are two digital watermarking techniques. Digital watermarking techniques based on correlation and digital watermarking techniques that are not based on correlation. In previous work, we proposed a DWT2 based CDMA image watermarking scheme to study the effects of using eight color spaces RGB, YCbCr, JPEG-YCbCr, YIQ, YUV, HSI, HSV and CIELab, on watermarking algorithms based on correlation techniques. This paper proposes a non correlation based image watermarking scheme in wavelet transform domain and tests it in the same color spaces, to develop studying, reach a comprehensive analysis and focus on satisfying the requirements of based non coloration watermarking algorithms. To achieve more security, imperceptibility and robustness of the proposed scheme, first, the binary watermark image encodes by applying ATM, CCM and exclusive OR. Then, the scrambled watermark embeds into intended quantized approximation coefficients of wavelet transform by LSB insertion technique.

    The internet has become an important resource to help people search for online medication information. This study aims to report the prevalence and profile of Saudi online medication seeking behavior. Conducted via a web-based survey with Twitter participants between January-February, 2015, the primary outcome measures were the self-reported rates of using the internet to search for medication related information. A valid sample of 4847 participants was collected over the period of the study. Out of the total participants, 68.3% (n=3311) were found to seek online medication related information frequently. Most of the social media users were female 83.5% (n=2766). The majority of respondents 63.6% (n= 3081) used Google, followed by Twitter 28.7% (n= 1392), Snapchat 21%, (n=1019), WhatsApp 13.8% (n= 670), Instagram 11.4%, (n= 553), and Facebook 5.5 % (n= 267), with few searching YouTube 1.3% (n=65) to access online medication information. Findings indicate that the Saudi population actively uses the internet and social media to obtain medication information. Further studies are needed to explore the influence of the internet and social media on user perception, attitude, and behavior with the use of online medication information.

    Life history (LH) theory provides an evolutionary theoretical framework for understanding individual differences in maturation, mating, reproduction, parenting, and social interaction. However, the psychometric assessment of human life history has been largely limited to generalized self-reports. Using template matching, this article examines the relationship between personality differences associated with slow-life history (slow-LH) and social behavior in 3 archival datasets. Two of these datasets include direct observations of behavior in the laboratory, and the 3rd provides self-reports of behavior in real life situations experienced within the preceding 24 hr. The results paint a consistent picture of the slow-LH individual as engaging in numerous adaptive social behaviors. However, when "normativeness" (the tendency for most people to be normal in both the statistical and evaluative sense) is statistically removed from the LH scores, a slightly different picture emerges. Both slow-LH and fast-LH persons display a number of behaviors that may be either adaptive or maladaptive in different contexts. Specifically, slow-LH individuals tended to behave in a manner that was considerate, kind, hard-working, and reliable but also socially awkward, insecure, and overcontrolling. Fast-LH individuals came across as talkative, socially skilled, dominant, and charming but also unpredictable, hostile, manipulative, and impulsive. These results are consistent with the evolutionary interpretation of LH strategies as being adapted to systematically different environments rather than better or worse approaches to reproductive fitness overall.

    Full Text Available Abstract Background Studies examining the correlates of school transport commonly fail to make the distinction between morning and afternoon school trips. The purpose of this study was to examine the prevalence and correlates of mode shift from passive in the morning to active in the afternoon among elementary and secondary school students in Ontario, Canada. Methods Data were derived from the 2009 cycle of the Ontario Student Drug Use and Health Survey (OSDUHS. 3,633 students in grades 7 through 12 completed self-administered questionnaires. Socio-demographic, behavioural, psychological, and environmental predictors of active school transport (AST were assessed using logistic regression. Results Overall, 47% and 38% of elementary school students reported AST to and from school, respectively. The corresponding figures were 23% and 32% for secondary school students. The prevalence of AST varied temporarily and spatially. There was a higher prevalence of walking/biking found for elementary school students than for secondary school students, and there was an approximate 10% increase in AST in the afternoon. Different correlates of active school transport were also found across elementary and secondary school students. For all ages, students living in urban areas, with a shorter travel time between home and school, and having some input to the decision making process, were more likely to walk to and from school. Conclusions Future research examining AST should continue to make the analytic distinction between the morning and afternoon trip, and control for the moderating effect of age and geography in predicting mode choice. In terms of practice, these variations highlight the need for school-specific travel plans rather than 'one size fits all' interventions in promoting active school transport.

    Full Text Available Background: The correlation between certain systemic diseases and ABO blood group is a well-documented fact. The association between periodontal disease and ABO blood group is not studied in relation to a specific geographic location. Here is a study conducted on a group of patients belonging to South Kanara district of Karnataka state. Materials and Methods: A total of 750 subjects aged between 30and 38 years belonging to South Kanara district were selected on random basis. The study subjects were segregated into healthy/mild gingivitis, moderate/severe gingivitis, and periodontitis group, based on Loe and Silness index and clinical attachment loss as criteria. The study group was further categorized and graded using Ramfjord′s periodontal disease index. Blood samples were collected to identify ABO blood group. Results: Prevalence of blood group O was more in South Kanara district, followed by blood groups B and A, and the least prevalent was AB. The percentage distribution of subjects with blood groups O and AB was more in healthy/mild gingivitis group (group I and moderate/severe gingivitis group (group II, while subjects with blood groups B and A were more in periodontitis group III. There was increased prevalence of subjects with blood groups O and AB with healthy periodontium, while subjects with blood groups B and A showed inclination toward diseased periodontium. Conclusion: There is a correlation existing between periodontal disease and ABO blood group in this geographic location. This association can be due to various blood group antigens acting as receptors for infectious agents associated with periodontal disease. This broad correlation between periodontal disease and ABO blood group also points toward susceptibility ofthe subjects with certain blood groups to periodontal disease.

    Full Text Available Background-There are marked sex differences in cardiovascular disease [CVD] manifestation. It is largely unknown how the distribution of CVD risk factors or intermediate phenotypes explain sex-specific differences.Methods and Results-In 5000 individuals of the population-based Gutenberg Health Study, mean age 55±11 years, 51% males, we examined sex-specific associations of classical CVD risk factors with intima-media thickness, ankle-brachial index, flow-mediated dilation, peripheral arterial tonometry, echocardiographic and electrocardiographic variables. Intermediate cardiovascular phenotypes were related to prevalent CVD (coronary artery disease, heart failure, stroke, myocardial infarction, lower extremity artery disease [LEAD] N=561.We observed differential distributions of CVD risk factors with a higher risk factor burden in men. Manifest coronary artery disease, stroke, myocardial infarction and LEAD were more frequent in men; the proportion of heart failure was higher in women. Intermediate phenotypes showed clear sex differences with more beneficial values in women. Fairly linear changes towards less beneficial values with age were observed in both sexes. In multivariable-adjusted regression analyses age, systolic blood pressure and body mass index were consistently associated with intermediate phenotypes in both sexes with different ranking according to random forests, maximum model R² 0.43. Risk factor-adjusted associations with prevalent CVD showed some differences by sex. No interactions by menopausal status were observed. Conclusions-In a population-based cohort we observed sex differences in risk factors and a broad range of intermediate phenotypes of noninvasive cardiovascular structure and function. Their relation to prevalent CVD differed markedly. Our results indicate the need of future investigations to understand sex differences in CVD manifestation.

    Abstract Chinese rural-to-urban migrant workers (MWs) who are employed in service industry are a rapidly growing population in urban China. Like other MWs, service industry MWs (SIMWs) are generally excluded from the mainstream of city societies, but unlike other MWs, they are more marginalized in cities. Social isolation increases the feelings of loneliness; however, there are little empirical data on the epidemiology of loneliness of SIMWs. The present study aimed to investigate the prevalence and associated factors of loneliness among SIMWs in Shenzhen, China. By using respondent-driven sampling, 1979 SIMWs were recruited and administered with standardized questionnaires to collect data on sociodemographics, physical health, and migration-related characteristics. Loneliness and social support were measured with a single-item self-report question “Do you feel lonely often?” and Multidimensional Scale of Perceived Social Support (MSPSS), respectively. 18.3% of SIMWs reported feeling lonely often. Being aged 60 years or older (odds ratio [OR] = 2.30), marital status of “others” (OR = 2.77), being physically ill in the last 2 weeks (OR = 1.46), migrating alone (OR = 1.97), working >8 hours/day (OR = 1.06), MSPSS inside family subscale score ≤18 (OR = 1.80), and MSPSS outside family subscale score ≤38 (OR = 1.50) were significantly associated with increased risk of loneliness in SIMWs. Loneliness is prevalent in Chinese SIMWs and should be seen as a major public health issue. The high prevalence and many negative health consequences of loneliness highlight the importance of routine screening, evaluation, and treatment of loneliness in this vulnerable population.

    Background: Mycoplasma genitalium (M. genitalium) has been shown to be involved in chronic non-gonococcal urethritis (NGU). However, the prevalence and determinants of this emerging sexually transmissible infection among prostatitis patients remain obscure. Methods: Two hundred and thirty-five patients diagnosed with prostatitis and 152 health controls from sexually transmitted diseases (STD) clinics in Shanghai, China, were selected. M. genitalium was detected in the initial voided urine (VB1), midstream of urine (VB2), expressed prostatic secretion (EPS) and the opening urine after massage (VB3) by quantitative polymerase chain reaction (Q-PCR) targeting the Mycoplasma genitalium adhesion protein (MgPa). An infection of the prostate was considered positive if a uropathogen was found only in the EPS sample or VB3, or if it was at least four-fold greater in EPS or VB3 than in VB1 or VB2. The prostatitis patients with M. genitalium infection were treated with azithromycin. Results: The prevalence of M. genitalium infection was significantly higher among the prostatitis group than the control group (10 vs 3%, P = 0.005). Among the prostatitis group, M. genitalium infection was significantly associated with those patients who received treatment for genitourinary infection previously than those patients who did not (17 vs 6%; adjusted OR, 4.011; 95% CI, 1.562-10.300). The symptoms were totally or partially improved in 83% per cent (19/23) of prostatitis patients with M. genitalium, positive in EPS and M. genitalium turned negative after azithromycin treatment. Conclusions: M. genitalium was prevalent in the patients with prostatitis, particularly in those who received ineffective antibiotic treatment for the bacterium, and was identified as having a significant association of prostatitis.

    Full Text Available This is the first report of registration at birth, and of incidence of major structural birth defects (BD obtained in Gaza at Al Shifa Hospital, where 28% of total births in Gaza Strip occur. Doctors registered 4,027 deliveries, with a protocol comprehensive of clinical, demographic, kin and environmental questions. Prevalence of BD is 14/1,000, without association with intermarriage or gender of the child. Prevalence of late miscarriages and still births are respectively 23.3/1,000 and 7.4/1,000, and of premature births 19.6/1,000. Couples with a BD child have about 10 times higher frequency of recurrence of a BD in their progeny than those with normal children, but none of their 694 siblings and only 10/1,000 of their 1,423 progeny had BD, similar to the frequency in general population. These data suggest occurrence of novel genetic and epigenetic events in determination of BD. Children with BD were born with higher frequency (p < 0 001 in families where one or both parents were under “white phosphorus” attack, that in the general population. Bombing of the family home and removal of the rubble were also frequently reported by couples with BD occurrence. These data suggests a causative/favoring role of acute exposure of parents to the weapons-associated contaminants, and/or of their chronic exposure from their persistence in the environment on the embryonic development of their children.

    This paper introduces a new model for node behavior namely Correlated Node Behavior Model which is an extension of Node Behavior Model. The model adopts semi Markov process in continuous time which clusters the node that has correlation. The key parameter of the process is determined by five probabilistic parameters based on the Markovian model. Computed from the transition probabilities of the semi-Markov process, the node correlation impact on network survivability and resilience can be measure quantitatively. From the result, the quantitative analysis of correlated node behavior on the survivability is obtained through mathematical description, and the effectiveness and rationality of the proposed model are verified through numerical analysis. The analytical results show that the effect from correlated failure nodes on network survivability is much severer than other misbehaviors.

    Sexual transmission is the fastest growing route of HIV transmission in China, and Trichomonas vaginalis(TV) can facilitate HIV transmission and acquisition. Our goal was to determine the prevalence and correlates of TV infection among female sex workers (FSWs). This cross-sectional study was conducted in a city of Yunnan Province in southern China, with confidential face-to-face interviews and laboratory tests for TV (wet mount) and other sexually transmitted infections. A total of 734 FSWs participated in the study. The prevalence of TV was 9.0% (95% confidence interval [CI] 7.02-11.30). In multivariate analyses, adjusted odds ratios of TV infection were 3.0 (95% CI 1.47-6.01) for herpes simplex virus type 2 seropositive, 2.4 (95% CI 1.37-4.14) for Chlamydia trachomatis infection, 2.6 (95% CI 1.30-5.31) for genital ulcer, 1.9 (95% CI 1.11-3.30) for starting age in commercial sex <20 years, and 0.5 (95% CI 0.27-0.87) for vaginal douching. We found a relatively high prevalence of TV infection among FSWs in Yunnan Province. A range of control strategies that include TV screening are recommended among FSWs, which could contribute significantly to the disruption of transmission by the provision of immediate treatment.

    Correlated variability of neuronal responses is an important factor in estimating sensory parameters from a population response. Large correlations among neurons reduce the effective size of a neural population and increase the variation of the estimates. They also allow the activity of one neuron to be informative about impending perceptual decisions or motor actions on single trials. In extrastriate visual area MT of the rhesus macaque, for example, some but not all neurons show nonzero "choice probabilities" for perceptual decisions or non-zero "MT-pursuit" correlations between the trial-by-trial variations in neural activity and smooth pursuit eye movements. To understand the functional implications of zero versus nonzero correlations between neural responses and impending perceptions or actions, we took advantage of prior observations that specific frequencies of local field potentials reflect the correlated activity of neurons. We found that the strength of the spike-field coherence of a neuron in the gamma-band frequency range is related to the size of its MT-pursuit correlations for eye direction, as well as to the size of the neuron-neuron correlations. Spike-field coherence predicts MT-pursuit correlations better for direction than for speed, perhaps because the topographic organization of direction preference in MT is more amenable to creating meaningful local field potentials. We suggest that the relationship between spiking and local-field potentials is stronger for neurons that have larger correlations with their neighbors; larger neuron-neuron correlations create stronger MT-pursuit correlations. Neurons that lack strong correlations with their neighbors also have weaker correlations with pursuit behavior, but still could drive pursuit strongly.

  18. Neudesin is involved in anxiety behavior: structural and neurochemical correlates

    Full Text Available Neudesin (also known as neuron derived neurotrophic factor, Nenf is a scarcely studied putative non-canonical neurotrophic factor. In order to understand its function in the brain, we performed an extensive behavioral characterization (motor, emotional and cognitive dimensions of neudesin-null mice. The absence of neudesin leads to an anxious-like behavior as assessed in the elevated plus maze, light/dark box and novelty suppressed feeding tests, but not in the acoustic startle test. This anxious phenotype is associated with reduced dopaminergic input and impoverished dendritic arborizations in the dentate gyrus granule neurons of the ventral hippocampus. Interestingly, shorter dendrites are also observed in the bed nucleus of the stria terminalis (BNST of neudesin-null mice. These findings lead us to suggest that neudesin is a novel relevant player in the maintenance of the anxiety circuitry.

    Full Text Available No matter how hard we focus on a task, we cannot prevent our attention from wandering. By recording simultaneously from dozens of neurons in visual cerebral cortex, it is now possible to obtain a nearly instantaneous measure of how visual attention is allocated. This approach is providing new insights into the mechanisms that control attention to locations and features, and how short-term drifts in attention affect behavioral performance.

    Post-traumatic stress disorder (PTSD) is associated with adverse outcomes and increased mortality in cardiac patients. No studies have examined PTSD in the adult congenital heart disease (ACHD) population. The objectives of this study were to assess the prevalence of self-reported symptoms of PTSD in patients with ACHD and explore potential associated factors. Patients were enrolled from an outpatient ACHD clinic and completed several validated measures including the Impact of Event Scale-Revised, PTSD Checklist-Civilian Version, and the Hospital Anxiety and Depression Scale. Clinical data were abstracted through medical data review. A total of 134 participants (mean age 34.6 ± 10.6; 46% men) were enrolled. Of the 127 participants who completed the Impact of Event Scale-Revised, 14 (11%) met criteria for elevated PTSD symptoms specifically related to their congenital heart disease or treatment. Of the 134 patients who completed PTSD Checklist-Civilian Version, 27 (21%) met criteria for global PTSD symptoms. In univariate analyses, patients with congenital heart disease-specific PTSD had their most recent cardiac surgery at an earlier year (p = 0.008), were less likely to have attended college (p = 0.04), had higher rates of stroke or transient ischemic attack (p = 0.03), and reported greater depressive symptoms on the Hospital Anxiety and Depression Scale (7 vs 2, p PTSD were depressive symptoms (p PTSD is present in 11% to 21% of subjects seen at a tertiary referral center for ACHD. The high prevalence of PTSD in this complex group of patients has important implications for the medical and psychosocial management of this growing population.

    Bisexual men (men who have sex with men and women) are potential epidemiological bridges responsible for the spread of HIV and other sexually transmitted infections from men who have sex with men only to the heterosexual population. We aimed to estimate the prevalence of syphilis and HIV and the factors associated with syphilis infection among men who have sex with men and women and men who have sex with men only from Shijiazhuang, China. In 2011-2013, a cross-sectional cohort of 427 men who have sex with men was recruited by a snowball sampling method and tested for syphilis and HIV. Chi square and logistic regression were performed to identify syphilis risk factors. Among the 427 men who have sex with men, 71 (16.6%) cases were syphilis-positive and 16 cases (3.7%) were HIV-positive. The proportions of men who have sex with men and women and men who have sex with men only in the total sample were 31.4% and 68.6%, respectively. Men who have sex with men and women exhibited double the syphilis prevalence of men who have sex with men only and were more likely to practice insertive anal sex. Higher education level, being married, having more male partners, and both receptive and insertive anal sex roles were associated with syphilis among men who have sex with men and women. Residing in suburban areas, being married, being HIV positive, and an absence of desire to change sexual orientation were associated with syphilis among men who have sex with men only. Therefore, men who have sex with men and women represent an important sub-group in the syphilis epidemic and further interventions should be developed to reduce risk among different sub-sets of men who have sex with men.

    Full Text Available Abstract Background Adult separation anxiety disorder (ASAD has been identified recently, but there is a paucity of data about its prevalence and associated characteristics amongst anxiety patients. This study assessed the prevalence and risk factor profile associated with ASAD in an anxiety clinic. Methods Clinical psychologists assigned 520 consecutive patients to DSM-IV adult anxiety subcategories using the SCID. We also measured demographic factors and reports of early separation anxiety (the Separation Anxiety Symptom Inventory and a retrospective diagnosis of childhood separation anxiety disorder. Other self-report measures included the Adult Separation Anxiety Symptom Questionnaire (ASA-27, the Depression, Anxiety, Stress Scales (DASS-21, personality traits measured by the NEO PI-R and the Work and Social Adjustment Scale. These measures were included in three models examining for overall differences and then by gender: Model 1 compared the conventional SCID anxiety subtypes (excluding PTSD and OCD because of insufficient numbers; Model 2 divided the sample into those with and without ASAD; Model 3 compared those with ASAD with the individual anxiety subtypes in the residual group. Results Patients with ASAD had elevated early separation anxiety scores but this association was unique in females only. Except for social phobia in relation to some comparisons, those with ASAD recorded more severe symptoms of depression, anxiety and stress, higher neuroticism scores, and greater levels of disability. Conclusions Patients with ASAD attending an anxiety clinic are highly symptomatic and disabled. The findings have implications for the classification, clinical identification and treatment of adult anxiety disorders.

    We assessed with computed tomography (CT) densitometry the prevalence of emphysema in 266 (175 men and 91 women; mean age 64{+-}4 years) smokers and former smokers enrolled in the ITALUNG trial of lung cancer screening with low-dose thin-slice CT. Whole-lung volume and the relative area at -950 Hounsfield units (RA{sub 950}) and mean lung attenuation (MLA) in 1 of every 10 slices (mean, 24 slices per subject) were measured. Lung volume, MLA and RA950 significantly correlated each other and with age. Average RA950>6.8% qualifying for emphysema was present in 71(26.6%) of 266 subjects, with a higher prevalence in men than in women (30.3% vs 19.8%; p=0.003). Only in smokers was a weak (r=0.18; p=0.05) correlation between RA950 and packs/year observed. In multiple regression analysis, the variability of RA950 (R2=0.24) or MLA (R2=0.34) was significantly, but weakly explained by age, lung volume and packs/year. Other factors besides smoking may also have a significant role in the etiopathogenesis of pulmonary emphysema. (orig.)

    Full Text Available Abstract Background Smoking is one of the leading causes of premature death particularly in developing countries. The prevalence of smoking is high among the general male population in Bangladesh. Unfortunately smoking information including correlates of smoking in the cities especially in the urban slums is very scarce, although urbanization is rapid in Bangladesh and slums are growing quickly in its major cities. Therefore this study reported prevalences of cigarette and bidi smoking and their correlates separately by urban slums and non-slums in Bangladesh. Methods We used secondary data which was collected by the 2006 Urban Health Survey. The data were representative for the urban areas in Bangladesh. Both slums and non-slums located in the six City Corporations were considered. Slums in the cities were identified by two steps, first by using the satellite images and secondly by ground truthing. At the next stage, several clusters of households were selected by using proportional sampling. Then from each of the selected clusters, about 25 households were randomly selected. Information of a total of 12,155 adult men, aged 15–59 years, was analyzed by stratifying them into slum (= 6,488 and non-slum (= 5,667 groups. Simple frequency, bivariable and multivariable logistic regression analyses were performed using SPSS. Results Overall smoking prevalence for the total sample was 53.6% with significantly higher prevalences among men in slums (59.8% than non-slums (46.4%. Respondents living in slums reported a significantly (P bidis (slums = 11.4% and non-slums = 3.2%, P bidis (OR = 1.90, 95% CI = 1.58–2.29 and any of the two (OR = 1.23, 95% CI = 1.13–1.34 among men living in slums as compared to those living in non-slums when controlled for age, division, education, marital status, religion, birth place and types of work. Division, education and types of work were the common significant correlates for both cigarette and bidi smoking in slums

    The discourse of dual burden caused through underweight and overweight is well-documented globally but this issue and its connection with women's health in Bangladesh is yet to be explored widely. To enrich the current debate, this study, in the context of Bangladesh, examines the patterns, prevalence, and socioeconomic factors influencing the ever-married women of being underweight and overweight over normal weight. Data used in this study have been extracted from the most recent 2011 Bangladesh Demographic and Health Survey. To achieve results connected with the research objectives, both bivariate and multivariate statistical analyses have been employed. In bivariate analysis, we used seven categories of BMI cutoff points for Asian countries as prescribed by World Health Organization (WHO). Multinomial logistic regression model was constructed to investigate the net effect of socioeconomic factors on underweight, pre-overweight, and overweight over normal weight. The results confirm the co-existence of underweight and overweight among women as we found the prevalence of underweight, normal weight, pre-overweight, overweight, and obesity to be 24.1%, 46.7%, 12.8%, 13.5%, and 2.9% respectively. Compared to the richest, the women from the poorest households were significantly (poverweight (OR=0.15, 95% CI 0.12-0.19) over normal weight. The urban women, compared to their rural counterparts, were significantly (poverweight (OR=1.33, 95% CI 1.18-1.51) than normal weight. The other socioeconomic grades that were most marked to be underweight and overweight are age, women's education, marital status, age at first childbirth, parity, number of children aged ≤ 5 years at the household, and food security. The findings confirm the dual burden of both under- and overweight. Systematic and regular monitoring and surveillance of the social trajectory of nutritional status of women and men in Bangladesh is crucial to develop opposite strategy that addresses the persistent and

    Full Text Available Christopher Zamani, Jared D Elzey, James EK Hildreth Center for AIDS Health Disparities Research at Meharry Medical College, Nashville, Tennessee, USA Purpose: After decades of research, AIDS continues to be a major pandemic and to date, adaptive immunity vaccine designs have had little to no success. Data indicate the alloimmune response is a potent mitigator of human immunodeficiency virus (HIV infection, for which experiments of nature should be demonstrable to justify pursuit of an alloimmune vaccine strategy. We sought to determine if large-scale alloimmune diversity correlates with lower HIV infection rates. Methods: Using published data of African linguistic groups to determine sub-Saharan country ethnicity profiles as a proxy for human leukocyte antigen (HLA diversity, a correlation analysis was performed against respective sub-Saharan country HIV infection rates. Ethnicity data from 37 sub-Saharan nations in 2003 and from 38 nations in 2005 were used to calculate the Meyers-Macintosh ethnic diversity score for each nation as the independent variable. World Health Organization data on HIV infection rates for the same countries were used as the dependent variable. The main outcome measure was the correlation coefficient of ethnic diversity versus HIV infection rate. Results: A significant negative correlation was shown between ethnic diversity and HIV infection: for 2003 data, -0.4586 (two-tailed P-value of 0.0043; and, for 2005 data, -0.3866 (two-tailed P-value of 0.0165. Conclusion: In conjunction with substantial evidence that alloimmunity confers protection against HIV transmission and recent work identifying specific anti-HIV mechanisms, this analysis strongly justifies an HLA-based alloimmune vaccine strategy against HIV.

    Full Text Available Obesity has reached epidemic proportions globally and the prevention of adult obesity will require prevention and management of childhood obesity. A study was conducted to determine the prevalence and behavioral determinants of overweight and obesity in school going adolescents. A total of 660 adolescents from affluent and nonaffluent schools were taken. Overweight and obesity was defined as per World Health Organization 2007 growth reference. Prevalence of overweight and obesity was 9.8% and 4.8%, respectively. Prevalence of both overweight and obesity was higher among males. Statistically significant difference was found in prevalence of overweight and obesity among affluent schools (14.8% and 8.2% and nonaffluent schools (4.8% and 1.5%. Important determinants of overweight and obesity were increased consumption of fast food, low physical activity level and watching television for more than 2 h/day. The prevalence of obesity is high even in small cities. Dietary behavior and physical activity significantly affect weight of adolescent children.

    Development and maintenance of unsupervised intelligent activity relies on an active interaction with the environment. Such active exploratory behavior plays an essential role in both the development and adult phases of higher biological systems including humans. Exploration initiates a self-organization process whereby a coherent fusion of different sensory and motor modalities can be achieved (sensory-motor development) and maintained (adult rearrangement). In addition, the development of intelligence depends critically on an active manipulation of the environment. These observations are in sharp contrast with current attempts of artificial intelligence and various neural network models. In this paper, we present a neural network model that combines internal drives and environmental cues to reach behavioral decisions for the exploratory activity. The vision system consists of an ambient and a focal system. The ambient vision system guides eye movements by using nonassociative learning. This sensory based attentional focusing is augmented by a `cognitive' system using models developed for various aspects of frontal lobe function. The combined system has nonassociative learning, reinforcement learning, selective attention, habit formation, and flexible criterion categorization properties.

Here, detailed clinical phenotypes were recorded, and the COL1A1 and COL1A2 genes were analyzed in 164 Swedish OI families (223 individuals). Averages for bone mineral density (BMD), height and yearly fracture rate were calculated and related to OI and mutation type. N-terminal helical mutations in both the α1- and α2-chains were associated with the absence of dentinogenesis imperfecta (P95% of the complete Swedish pediatric OI population. The prevalence of OI types I, III, and IV was 5.16, 0.89, and 1.35/100 000, respectively (7.40/100 000 overall), corresponding to what has been estimated but not unequivocally proven in any population. Collagen I mutation analysis was performed in the family of 97% of known cases, with causative mutations found in 87%. Qualitative mutations caused 32% of OI type I. The data reported here may be helpful to predict phenotype, and describes for the first time the genetic epidemiology in >95% of an entire OI population. PMID:25944380

    Full Text Available PURPOSE: This study explores whether gender, age and race differences in oral sexual behavior account for the demographic distribution of oral human papillomavirus infection (HPV and HPV-positive oropharyngeal cancer (HPV-OSCC. METHODS: This analysis included 2,116 men and 2,140 women from NHANES (2009-10 who answered a behavioral questionnaire and provided an oral-rinse sample for HPV detection. Weighted prevalence estimates and prevalence ratios (PR were calculated for sexual behaviors and oral HPV infection by gender, age-cohort (20-29, 30-44, 45-59, 60-69, and race, and contrasted with incidence rate ratios (IRR of OSCC from SEER 2009. Multivariate logistic regression was used to evaluate predictors of oral sexual behavior and oral HPV16 infection. RESULTS: Differences in oral sexual behavior were observed by gender, age-cohort and race. Most men (85.4% and women (83.2% had ever performed oral sex, but men had more lifetime oral and vaginal sexual partners and higher oral HPV16 prevalence than women (each p<0.001. 60-69 year olds (yo were less likely than 45-59 or 30-44 (yo to have performed oral sex (72.7%, 84.8%, and 90.3%, p<0.001, although oral HPV16 prevalence was similar. Prevalence ratios (PR of ever oral sex in men vs. women (PR = 1.03, and 45-59 vs. 30-44 year-old men (PR = 0.96 were modest relative to ratios for oral HPV16 infection (PRs = 1.3-6.8 and OSCC (IRR = 4.7-8.1. In multivariate analysis, gender, age-cohort, and race were significant predictors of oral sexual behavior. Oral sexual behavior was the primary predictor of oral HPV16 infection; once this behavior was adjusted for, age-cohort and race were no longer associated with oral HPV16. CONCLUSION: There are differences in oral sexual behaviors when considering gender, age-cohort and race which explain observed epidemiologic differences in oral HPV16 infection across these groups.

    Manipulation is an important issue for both developed and emerging stock markets. Many efforts have been made to detect manipulation in stock markets. However, it is still an open problem to identify the fraudulent traders, especially when they collude with each other. In this paper, we focus on the problem of identifying the anomalous traders using the transaction data of eight manipulated stocks and forty-four non-manipulated stocks during a one-year period. By analyzing the trading networks of stocks, we find that the trading networks of manipulated stocks exhibit significantly higher degree-strength correlation than the trading networks of non-manipulated stocks and the randomized trading networks. We further propose a method to detect anomalous traders of manipulated stocks based on statistical significance analysis of degree-strength correlation. Experimental results demonstrate that our method is effective at distinguishing the manipulated stocks from non-manipulated ones. Our method outperforms the traditional weight-threshold method at identifying the anomalous traders in manipulated stocks. More importantly, our method is difficult to be fooled by colluded traders.

    Various flow effects of nuclear and hadronic origin are investigated in nucleus-nucleus collisions. Nuclear emulsion data collected from {sup 84}Kr + Ag/Br interaction at an incident energy of 1.52 GeV per nucleon and from {sup 28}Si + Ag/Br interaction at an incident energy of 14.5 GeV per nucleon are used in the investigation. The transverse momentum distribution and the flow angle analysis show that collective behavior, like a bounce-off effect of the projectile spectators and a sidesplash effect of the target spectators, are present in our event samples. From an azimuthal angle analysis of the data we also see a direct flow of the projectile fragments and of the produced charged particles. On the other hand, for both data samples the target fragments exhibit a reverse flow, while the projectile fragments exhibit an elliptic flow. Relevant flow parameters are measured.

    Full Text Available Prisons are considered high-risk environments for HIV transmission. This study aimed to measure HIV and syphilis prevalence and risk behaviors among inmates in Indonesia. An integrated HIV and syphilis biological and behavior survey was conducted on random samples of 900 male and 402 female inmates in 2010. Male inmates from 18 general prisons and detention centers were randomly selected using probability proportional to size. Female inmates were randomly selected from nine eligible institutions. HIV tests included two rapid tests and enzyme-linked immunosorbent assay (ELISA for quality control. A rapid test was used for syphilis. Audio computer-assisted self-interview was used for collecting risk behavior information. HIV prevalence was 1.1% among male and 6.0% among female inmates. Syphilis prevalence was 5.1% for male and 8.5% for female inmates. A history of injecting drugs was the most important risk factor for HIV infection in male inmates; for females, it was co-infection with syphilis and being sentenced for illicit drug use. Inmates’ high-risk activities in prison included tattooing, piercing and inserting genital accessories without sterile equipment, and sex without condoms. The study found high-risk practices by male inmates and high HIV and syphilis prevalence in female inmates. Inmates need harm reduction initiatives.

    Full Text Available The lack of adequate and standardized recording of leading risk factors for morbidity and mortality in medical records have downstream effects on research based on administrative databases. The measurement of healthcare is increasingly based on risk-adjusted outcomes derived from coded comorbidities in these databases. However inaccurate or haphazard assessment of risk factors for morbidity and mortality in medical record codes can have tremendous implications for quality improvement and healthcare reform.We aimed to compare the prevalence of obesity, overweight, tobacco use and alcohol abuse of a large administrative database with a direct data collection survey.We used the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM codes for four leading risk factors in the United States Nationwide Inpatient Sample (NIS to compare them with a direct survey in the Behavioral Risk Factor Surveillance System (BRFSS in 2011. After confirming normality of the risk factors, we calculated the national and state estimates and Pearson's correlation coefficient for obesity, overweight, tobacco use and alcohol abuse between NIS and BRFSS.Compared with direct participant questioning in BRFSS, NIS reported substantially lower prevalence of obesity (p<0.01, overweight (p<0.01, and alcohol abuse (p<0.01, but not tobacco use (p = 0.18. The correlation between NIS and BRFSS was 0.27 for obesity (p = 0.06, 0.09 for overweight (p = 0.55, 0.62 for tobacco use (p<0.01 and 0.40 for alcohol abuse (p<0.01.The prevalence of obesity, overweight, tobacco smoking and alcohol abuse based on codes is not consistent with prevalence based on direct questioning. The accuracy of these important measures of health and morbidity in databases is critical for healthcare reform policies.

    Full Text Available The objective of this study was to determine the prevalence of depressive symptoms in Jamaican adolescents and examine its association with individual and family factors. We used an abbreviated form of the Beck's Depression Inventory II (BDI-II to assess depressive symptoms among 748 students, attending public high schools in the parish of Hanover Jamaica. In the analysis, we classified adolescents with scores in the upper quartile of the depressive symptom score as having depressive symptoms. Multivariate logistic regression was used to determine the predictors of depressive symptoms. 14.2% of participants reported depressive symptoms. There was association between engagement in sexual activity [Odds Ratio (OR = 1.61, 95% Confidence Interval (CI = 1.02-2.51], parental monitoring of adolescent activity (OR=2.04, 95%CI=1.33 -3.12, maternal affection and support (OR= 4.07, 95%CI= 2.62-6.33, and paternal affection and support (OR= 1.58, 95%CI= 1.05-2.39 with self reported depressive symptoms at the bivariate level. In the final model, depressive symptoms was associated with perceived lack of maternal affection and support (OR= 4.06, 95%CI= 2.61-6.32 and showed marginal association with being sexually experienced (OR= 1.59, 95%CI= 1.00-2.52. As most homes are female-headed, establishing support systems for the mother to take care of their adolescent children may decrease the odds of depressive symptoms. Sexually experienced adolescents may require screening for depression. Further research is required to fully explore all factors that could predispose Jamaican adolescents to depression.

  1. Symmetry Detection in Visual Impairment: Behavioral Evidence and Neural Correlates

    Full Text Available Bilateral symmetry is an extremely salient feature for the human visual system. An interesting issue is whether the perceptual salience of symmetry is rooted in normal visual development. In this review, we discuss empirical work on visual and tactile symmetry detection in normally sighted and visually impaired individuals. On the one hand, available evidence suggests that efficient visual symmetry detection may need normal binocular vision development. On the other hand, converging evidence suggests that symmetry can develop as a principle of haptic perceptual organization in individuals lacking visual experience. Certain features of visual symmetry detection, however, such as the higher salience of the patterns containing a vertical axis of symmetry, do not systematically apply to the haptic modality. The neural correlates (revealed with neuroimaging associated with visual and haptic symmetry detection are also discussed.

    This article investigates the effect for random pinning models of long range power-law decaying correlations in the environment. For a particular type of environment based on a renewal construction, we are able to sharply describe the phase transition from the delocalized phase to the localized one, giving the critical exponent for the (quenched) free-energy, and proving that at the critical point the trajectories are fully delocalized. These results contrast with what happens both for the pure model (i.e. without disorder) and for the widely studied case of i.i.d. disorder, where the relevance or irrelevance of disorder on the critical properties is decided via the so-called Harris Criterion.

  3. Male circumcision and sexual risk behaviors may contribute to considerable ethnic disparities in HIV prevalence in Kenya: an ecological analysis.

    Chris Richard Kenyon

    Full Text Available HIV prevalence varies between 0.8 and 20.2% in Kenya's various ethnic groups. The reasons underlying these variations have not been evaluated before.We used data from seven national surveys spanning the period 1989 to 2008 to compare the prevalence of a range of risk factors in Kenya's ethnic groups. Spearman's and linear regression were used to assess the relationship between HIV prevalence and each variable by ethnic group.The ethnic groups exhibited significant differences in a number of HIV related risk factors. Although the highest HIV prevalence group (the Luo had the highest rates of HIV testing (Men 2008 survey: 56.8%, 95% CI 51.0-62.5% and condom usage at last sex (Men 2008∶28.6%, 95% CI 19.6-37.6%, they had the lowest prevalence of circumcision (20.9%, 95% CI 15.9-26.0 the highest prevalence of sex with a non-married, non-cohabiting partner (Men: 40.2%, 95% CI 33.2-47.1% and pre-marital sex (Men 2008∶73.9%, 95% CI 67.5-80.3% and the youngest mean age of debut for women (1989 SURVEY: 15.7 years old, 95% CI 15.2-16.2. At a provincial level there was an association between the prevalence of HIV and male concurrency (Spearman's rho = 0.79, P = 0.04. Ethnic groups with higher HIV prevalence were more likely to report condom use (Men 2008 survey: R2 = 0.62, P = 0.01 and having been for HIV testing (Men 2008 survey: R2 = 0.47, P = 0.04.In addition to differences in male circumcision prevalence, variation in sexual behavior may contribute to the large variations in HIV prevalence in Kenya's ethnic groups. To complement the prevention benefits of the medical male circumcision roll-out in several parts of Kenya, interventions to reduce risky sexual behavior should continue to be promoted.

    Sexual orientation consists of multiple components. This study investigated both sexual identity and same-sex sexual behavior. Data came from the New Zealand Mental Health Survey, a nationally representative community sample of New Zealanders aged 16 years or older, interviewed face-to-face (N = 12,992, 48% male). The response rate was 73.3%. Self-reported sexual identity was 98.0% heterosexual, 0.6% bisexual, 0.8% homosexual, 0.3% "Something else," and 0.1% "Not sure." Same-sex sexual behavior with a partner was more common: 3.2% reported same-sex sexual experience only and 1.9% reported both experience and a relationship. For analysis of childhood and lifecourse, five sexuality groups were investigated: homosexual, bisexual, and heterosexual divided into those with no same-sex sexual experience, experience only, and experience and relationship. The non-exclusively heterosexual groups were more likely to have experienced adverse events in childhood. Educational achievement and current equivalized household income did not differ systematically across the sexuality groups. Only 9.4% of the exclusively heterosexual lived alone, compared with 16.7% of bisexuals and 19.0% of homosexuals. Heterosexuals were more likely than bisexuals or homosexuals to have ever married or had biological children, with differences more marked for males than for females. Heterosexuals with no same-sex sexual experience were more likely to be currently married than the other two heterosexual groups. Restricting comparisons to heterosexual, bisexual, and homosexual identification ignores the diversity within heterosexuals. Differences between the bisexual and homosexual groups were small compared with the differences between these groups and the exclusively heterosexual group, except for sex (80.8% of bisexuals were female).

    The aims of this study were to examine the prevalence rates and multilevel correlates of cyberbullying victims and perpetrators among male adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD) in Taiwan. The relationships between cyberbullying involvement and depression, anxiety, and suicidality were also examined. The experiences of cyberbullying victimization and perpetration in 251 male adolescents with ADHD were assessed. Logistic regression analysis was used to examine the correlates of cyberbullying victims and perpetrators. The relationships between cyberbullying involvement and depression, anxiety, and suicidality were examined using multiple regression analysis. A total of 48 (19.1%) and 36 (14.3%) participants reported that they were cyberbullying victims or perpetrators, respectively. Those who had increased age and a higher parental occupational socioeconomic status, and reported more severe traditional passive bullying victimization were more likely to be cyberbullying victims. Those who had increased age and combined-type ADHD, and reported lower BAS reward responsiveness, more severe Internet addiction and more severe traditional passive bullying perpetration were more likely to be cyberbullying perpetrators. Cyberbullying victims reported more severe depression and suicidality than those who were not cyberbullying victims. A high proportion of male adolescents with ADHD are involved in cyberbullying. Clinicians, educational professionals, and parents of adolescents should monitor the possibility of cyberbullying involvement among male adolescents with ADHD who exhibit the cyberbullying correlates identified in this study.

    Objective Bruxism is defined as the habitual nonfunctional forceful contact between occlusal tooth surfaces. The aim of this study was to determine the prevalence of bruxism and correlated factors in children referred to dental schools of Tehran, based on Parent's report. Methods This cross-sectional descriptive study was conducted on 600 4-12 year-old children with a mean age of 7.4±2.4 years, who were referred to four dental schools in Tehran. After collecting information with questionnaire filled out by parents, χ2, Fisher Test, Mann-Whitney and t-Test were used to analyze the data. Findings The prevalence of bruxism was 26.2%. Bruxism begun in average at the age of 4.9±2 years. Also it occurred 2.6 times more in children who had a family history of bruxism (father-mother), compared to children who didn't have such a history. 87% of children with bruxism had a history of distressing events in their life, and 13% of children with bruxism did not report any history of distressing events in their life. In this study most common oral habit was nail biting. In study of parasomnias, drooling was the most, and snoring the least reported sleep disorder. Bruxism in children with drooling was twice more than in other children. The prevalence of bruxism in children with temporomandibular disorder was 63.6% and in children without TMD was 24.7%. Conclusion Based on Parent's report, 26.2% of children showed bruxism and there was a significant relation between bruxism and mother's job, family history, distressing event in life, parasomnias, especially drooling and sleep walking, TMD, hyperactivity, depression, acrophobia and lygophobia.

    Bisexual behaviors may increase transmission pathways of HIV and sexually transmitted infections (STIs) from a higher prevalence group to lower prevalence groups in El Salvador. In 2008, men who have sex with men (MSM) were recruited in San Salvador and San Miguel using respondent driven sampling. Participants were interviewed and tested for HIV and STIs. Sixteen seeds and 797 MSM participated; 34.9% in San Salvador and 58.8% in San Miguel reported bisexual behavior. Bisexual behavior was associated with drug use (adjusted odds ratio (AOR) = 2.57, 95% CI: 1.30-5.06) and insertive anal sex (AOR = 5.45, 95% CI: 3.01-9.87), and inversely associated with having a stable male partner (AOR = 0.47, 95% CI: 0.26-0.84) and disclosing MSM behavior to family (AOR = 0.41, 95% CI: 0.22-0.75). Bisexual behavior was associated with risk behaviors with male and female partners that may be associated with HIV and STI transmission. Bisexual men displayed a distinct identity calling for tailored interventions.

    During reinforcement learning, phasic modulations of activity in midbrain dopamine neurons are conveyed to the dorsal anterior cingulate cortex (dACC) and basal ganglia (BG) and serve to guide adaptive responding. While the animal literature supports a role for the dACC in integrating reward history over time, most human electrophysiological studies of dACC function have focused on responses to single positive and negative outcomes. The present electrophysiological study investigated the role of the dACC in probabilistic reward learning in healthy subjects using a task that required integration of reinforcement history over time. We recorded the feedback-related negativity (FRN) to reward feedback in subjects who developed a response bias toward a more frequently rewarded ("rich") stimulus ("learners") versus subjects who did not ("non-learners"). Compared to non-learners, learners showed more positive (i.e., smaller) FRNs and greater dACC activation upon receiving reward for correct identification of the rich stimulus. In addition, dACC activation and a bias to select the rich stimulus were positively correlated. The same participants also completed a monetary incentive delay (MID) task administered during functional magnetic resonance imaging. Compared to non-learners, learners displayed stronger BG responses to reward in the MID task. These findings raise the possibility that learners in the probabilistic reinforcement task were characterized by stronger dACC and BG responses to rewarding outcomes. Furthermore, these results highlight the importance of the dACC to probabilistic reward learning in humans.

To evaluate the characteristics of the Houpt scales, the Ohio State University Behavioral Rating Scale (OSUBRS and the Venham Behavior Rating Scale when applied to preschool children undergoing conscious dental sedation. Design. This study included 27 children, 4–6 years old with early childhood caries that participated in a clinical trial (NCT02284204 that investigated two sedative regimes using oral midazolam/ketamine. Dental appointments were video-recorded; five calibrated observers assessed 1,209 minutes of video recording to score the children’s behavior, following the instructions of the investigated scales. Data were analyzed by descriptive analysis and Spearman correlation tests (P<0.05. Results. The Houpt overall behavior and the Venham scale were highly correlated (rho = −0.87; P<0.001. OSUBRS scores were better correlated with Houpt overall behavior and Venham ratings, when compared to Houpt scores in the categories for movement and crying. Conclusions. The Houpt overall behavior and the Venham scores are global scales that properly measure children’s behavior during dental sedation. Continuous assessment with OSUBRS through videos has a chance to give more precise data, while the Houpt categories can easily demonstrate children’s behavior during procedures.

A total of 447 consecutive patients with confirmed positive HIV status who were treated in different outpatient HIV centres in Austria and Germany were included. Nicotine dependence and stages of change were assessed by standardized questionnaires, and this was confirmed by measuring exhaled carbon monoxide. Prevalence of smoking was 49.4%. According to a multivariate logistic regression analysis, higher age (for each year of life OR = 0.96; 95% CI 0.92-1.00 and tertiary education level (OR = 0.43; 95% CI 0.15-0.79 were associated with a lower chance, and occasional (OR = 3.75; 95% CI 1.74-8.07 and daily smoking of the partner (OR 8.78; 95% CI 4.49-17.17 were significantly associated with a higher chance of smoking. Moderate (OR = 3.41; 95% CI = 1.30-9.05 and higher nicotine dependency level (OR = 3.40; 95% CI 1.46-7.94, were significantly associated with higher chance, and older age (for each year of life OR = 0.95; 95% CI = 0.91-0.99, with lower chance for readiness to quit smoking. Those results may be used to address preventive measures to quit smoking aimed at PLWHIV and the importance of addressing smoking habits.

    Full Text Available Background: The elderly population is growing, both in size and proportion with the total population and fall is a major problem for elderly. The aim of this study was to determine the prevalence and correlates of falls among elderly. Methodos: A cross sectional survey with Snowball sampling technique was used to recruit 100 elderly persons, 52 male and 48 female, 65 years and above. A modified self administered closed ended questionnaire was used. The data obtained were summarized using descriptive statistics of mean and Standard Deviation. Inferential statistics of Chi square, phi and Cramer’s V were used to analyze the data. Result: The result showed that 49% of the elderly had one or more falls with 65.3%falls occurring once and 34.7% occurring two or more times. Women fall more than men, accounting for 61.2% and 38.8% of the population respectively. A significant association was found between fall, age, sex, and reduced balance. Conclusion: The study concluded that there is high prevalence of falls in elderly with women experiencing more fall than men. It is recommended that modifications in the environment, counseling to the elderly and their families should be done to prevent further falls.

    Objective: To determine the frequency and clinical parameters, of clinically significant depressive symptoms among a type 2 diabetes (T2DM) sample from a Mediterranean area without an established diagnosis of depressive disorder (DD). Methods: 320 subjects with T2DM were recruited randomly from Primary-Care settings and the Endocrine Department from a tertiary center in Mallorca (Spain). 91 healthy individuals matched by age, gender and BMI were used as controls. All participating patients graded by the presence of DD by using the "Beck Depression Inventory" (BDI), considering pathological a cut-off score equal or greater than 16. Results: 27.2% T2DM subjects had significant symptoms of DD compared with 12.1% in the control group (pdepressive symptoms are more prevalent among Mediterranean T2DM subjects than in general population. Main clinical correlators of significant depressive symptoms are gender, marital status and BMI.

    We describe a Bethe ansatz based method to derive, starting from a multiple integral representation, the long-distance asymptotic behavior at finite temperature of the density-density correlation function in the interacting onedimensional Bose gas. We compute the correlation lengths in terms of solutions of non-linear integral equations of the thermodynamic Bethe ansatz type. Finally, we establish a connection between the results obtained in our approach with the correlation lengths stemming from the quantum transfer matrix method. (orig.)

    During reinforcement learning, phasic modulations of activity in midbrain dopamine neurons are conveyed to the dorsal anterior cingulate cortex (dACC) and basal ganglia and serve to guide adaptive responding. While the animal literature supports a role for the dACC in integrating reward history over time, most human electrophysiological studies of dACC function have focused on responses to single positive and negative outcomes. The present electrophysiological study investigated the role of the dACC in probabilistic reward learning in healthy subjects using a task that required integration of reinforcement history over time. We recorded the feedback-related negativity (FRN) to reward feedback in subjects who developed a response bias toward a more frequently rewarded (“rich”) stimulus (“learners”) versus subjects who did not (“non-learners”). Compared to non-learners, learners showed more positive (i.e., smaller) FRNs and greater dACC activation upon receiving reward for correct identification of the rich stimulus. In addition, dACC activation and a bias to select the rich stimulus were positively correlated. The same participants also completed a monetary incentive delay (MID) task administered during functional magnetic resonance imaging. Compared to non-learners, learners displayed stronger basal ganglia responses to reward in the MID task. These findings raise the possibility that learners in the probabilistic reinforcement task were characterized by stronger dACC and basal ganglia responses to rewarding outcomes. Furthermore, these results highlight the importance of the dACC to probabilistic reward learning in humans. PMID:18595740

    Overweight and obesity are important determinants of population health. Prevention of weight gain is dependent on the successful balancing of eating and physical activity behaviors. Planned promotion of healthful behavior requires insights into important and changeable determinants and correlates of behavior change. The modest effects of health education have induced a shift in focus from personal to environmental correlates of eating and physical activity behaviors. Six systematic reviews were conducted in 2005 of observational studies of environmental correlates and environmental interventions for weight-related eating behaviors and physical activity for children, adolescents, and adults. The reviews of 297 observational studies showed that few investigations of environmental associations have been replicated, and that most studies used weak research designs and nonvalidated self-report measures, were restricted to micro-environmental factors, and failed to apply multilevel analyses. There is, therefore, very little evidence for an association between environmental factors and weight-related behaviors. However, the reviews of 112 intervention studies indicated much stronger evidence for positive effects of micro-physical and sociocultural environmental changes on eating and physical activity behaviors. Inspired by quotes from Kurt Lewin, we argue that before large-scale environmental change interventions are launched, better-designed and -conducted research on the true importance of environmental factors, including macrolevel factors, for obesogenic behavioral change is needed. Such research should (1) develop better measures of environmental exposure, (2) attempt to integrate personal and environmental correlates of obesogenic behaviors, (3) take a solution-oriented, rather then a problem-oriented approach, and (4) identify access points for inducing behavior change instead of finding explanations for existing behavioral patterns.

    Full Text Available The purpose of the study was to investigate the correlations between self-image, self-esteem and some unwholesome behavior (alcohol consumption, cigarette and marihuana smoking, overeating at a meal, television watching and computer use in spare time in Slovenian adolescents. We used Offer Self-image Questionnaire for adolescents, Rosenberg Self-esteem Scale and Unwholesome behaviour Questionnaire that was made for the purpose of this research. In the research 392 high school students participated, aged around 15 and 18 years, approximately evenly represented by gender and age. Data was attained in class groups. The results showed low, but statistically significant correlations between some self-concept areas and unwholesome behavior. The highest correlations emerged between the sexual attitudes and all unwholesome behavior. Students with more positive sexual self-concept behave unhealthier. Family self, morals and vocational-educational goals were significantly negatively correlated with most of unwholesome behavior, which suggests that individuals with better family, moral and academic self-concept behave healthier. Significant negative correlations emerged also with coping self: individuals with better self-concept in mastery of the external world and superior adjustment behaved healthier. None of the unwholesome behavior correlated with self-esteem. Results are mainly consistent with previous studies, but also contribute to new comprehensions in psychological theory and practice.

    A total of 156 Staphylococcus aureus isolates were obtained from 330 imported fresh fish samples from three countries. Selective media were used for the isolation of S. aureus, and the isolates were confirmed by PCR. The isolates were tested for mecA gene, antibiotic resistance, and enterotoxin genes (sea, seb, sec, sed, see, seg, seh, and sei). Most isolates carried sea, seg, and sei genes, and seg-sei was the most frequent enterotoxin profile. About 88.5% of the S. aureus exhibited resistance to at least one antibiotic. High resistance to penicillin and ampicillin; low resistance to tetracycline, erythromycin, rifampin, and clindamycin; and very low resistance to cefotaxime, amoxicillin-clavulanic acid, gentamicin, and ciprofloxacin were exhibited by S. aureus from the three countries. In addition, some antibiotic resistance exhibited a strong correlation (P ≤ 0.01) with enterotoxigenicity in S. aureus. The study concluded that the large amount of globally traded fish increases the possibility of intercontinental transmission of enterotoxigenic and multidrug-resistant S. aureus through fish and highlights the potential influence of local fish handling and processing on consumer health worldwide. The introduction of periodic training in food safety and hygiene is essential to increase fish handlers' awareness of good hygienic practices in handling fish. These findings also enrich the ongoing debate about the risk of methicillin- and multidrug-resistant S. aureus as a foodborne pathogen compared with drug-susceptible S. aureus.

    Three hundred and eight Igbo women were randomly selected to respond to a number of questions on experiences, patterns and attitudes to domestic violence. Data was collected using structured questionnaires that were complemented with focus group discussions. The results show that 78.8% of the women have ever been battered by their male counterparts, out of which 58.9% reported battery during pregnancy, while 21.3% reported having been forced to have sexual intercourse. The study further revealed that the practice of female circumcision is still common among this Igbo population, and 52.6% were of the view that it should be continued. Multivariate logistic regression identified the correlates of these forms of violence such as age, place of residence, age at first marriage, type of marital union, level of income of women, and level of education of husband against women in Imo State. While wife battery is more pronounced in the urban area, forced sexual relationship and female genital mutilation are more pronounced in the rural areas. We recommend education of women and integration of services in reproductive health care service delivery as appropriate measures to eradicate these practice.

    Background Terrorist attacks are traumatic events that may result in a wide range of psychological disorders for people exposed. This review aimed to systematically assess the current evidence on major depressive disorder (MDD) after terrorist attacks. Methods A systematic review was performed. Studies included assessed the impact of human-made, intentional, terrorist attacks in direct victims and/or persons in general population and evaluated MDD based on diagnostic criteria. Results A total of 567 reports were identified, 11 of which were eligible for this review: 6 carried out with direct victims, 4 with persons in general population, and 1 with victims and general population. The reviewed literature suggests that the risk of MDD ranges between 20 and 30% in direct victims and between 4 and 10% in the general population in the first few months after terrorist attacks. Characteristics that tend to increase risk of MDD after a terrorist attack are female gender, having experienced more stressful situations before or after the attack, peritraumatic reactions during the attack, loss of psychosocial resources, and low social support. The course of MDD after terrorist attacks is less clear due to the scarcity of longitudinal studies. Conclusions Methodological limitations in the literature of this field are considered and potentially important areas for future research such as the assessment of the course of MDD, the study of correlates of MDD or the comorbidity between MDD and other mental health problems are discussed.

    Sleep paralysis (SP) occurs when rapid eye movement (REM) activity and concomitant paralysis of the skeletal muscles persist as an individual awakens and becomes conscious of his/her surroundings. SP is often accompanied by frightening hallucinations that some researchers suggest may be confounded with memories of childhood sexual abuse (CSA; [McNally, R. J., & Clancy, S. A. (2005). Sleep paralysis in adults reporting repressed, recovered, or continuous memories of childhood sexual abuse. Journal of Anxiety Disorders, 19, 595-602]). The purpose of this study was to evaluate relationships between CSA and SP. Based on self-report, participants (n=263) were categorized into three CSA groups: confirmed, unconfirmed, or no history of CSA. Relative to participants reporting no CSA history, those reporting CSA reported more frequent and more distressing episodes of SP. Post hoc analyses revealed that participants with clinically significant post-traumatic symptoms (irrespective of CSA history) also reported more frequent and more distressing episodes of SP. Significant correlations were found among SP indices and measures of post-traumatic symptoms, depression, dissociation, and absorption. Implications and future research directions are discussed.

    "The correlation between justice and organizational citizenship behavior and organizational identity among the nurses", aimed to correlate different aspects of personal feelings and organizational identity in a population of nurses. The population included all nurses working at hospitals affiliated to administry of health, treatment and medical education in Shahre-Kord (Iran) 2009. A sample consisting of 168 nurses was randomly selected out of the population. The study adopted a descriptive-correlative method. The Organizational Justice Questionnaire (1998), the Organizational Citizenship Questionnaire, and Organizational Identity Questionnaire (1982) were used for gathering data. Data was analyzed through multiple regression analysis. The findings revealed that 4 dimensions of organizational citizenship behavior (altruism, civic virtue, conscientiousness, and self-development) are correlated with organizational identity (R² = 0.612); and loyalty and obedience are correlated with distributional justice (R² = 0.71). Also, loyalty, altruism, and obedience are correlated with procedural justice (R² = 0.69) and loyalty and self-development are correlated with distributional justice (R² = 0.89). A correlation was also detected between interactional justice and organizational identity (R² = 0.89). The findings of the study could serve to identify the factors contributing to the creation and recreation of organizational identity, citizenship behavior and justice among nurses, to promote the performance of the organization, and to achieve organizational goals.

    The aim of the study was to assess the prevalence of temporomandibular disorders (TMD) and oral parafunctions, as well as their correlation with psychoemotional factors in Polish university students. The research was conducted in a group of 456 students (N = 456). The examination form comprised of two parts: survey and clinical examination. The research diagnostic criteria for temporomandibular disorders (RDC/TMD) was used in order to assess TMD. Symptoms of TMD were observed in 246 (54%) students after clinical examination. The largest group involved students with disc displacement (women: 132, 29%; men: 70, 15%). Women (164; 36%) suffered more frequently than men (82; 18%) from problems related to the stomatognathic system (P < 0.05), described themselves as easily excitable and emotionally burdened, and reported symptoms as tightness of the facial and neck muscles (P < 0.05). In 289 (64%) students intraoral symptoms concerning occlusal parafunctions were observed. In 404 (89%) examined students, nonocclusal parafunctions were recorded. A significant correlation between TMD and psychoemotional problems could be detected. TMD symptoms more often concern women. Emotional burden and excitability are factors predisposing muscular disorders.

    Full Text Available Objective: Previous research shows an association between obesity and attention deficit hyperactivity disorder (ADHD. The present study compares pre- and post-bariatric surgery patients using the internationally used Conners' Adult ADHD Rating Scale (CAARS™ to screen for ADHD. Methods: Matched samples pre- (N = 120 and post-bariatric surgery (N = 128 were compared using self-rating instruments to assess ADHD-relevant symptomatology, depression, eating-related psychopathology, and BMI. Results: Prevalence of probable ADHD did not differ between groups using the CAARS Index Scale T-scores; however, CAARS subscales Inattention/Memory and Self-Concept showed significantly lower scores in post-surgery patients. All CAARS subscales correlated significantly with each other, with depression and eating-related psychopathology. There was no correlation between ADHD and excess BMI loss in post-surgery patients. Conclusion: The findings suggest that a considerable number of patients before and after bariatric surgery screened positive for ADHD. It can be hypothesized that some core ADHD symptoms improve after surgery. Future studies are warranted to investigate the influence of ADHD on long-term surgery outcomes.

    2012-06-01

    Disparities in the prevalence of obesity in youth place minority and low socioeconomic status youth at increased risk for the development of chronic disease, such as metabolic syndrome and type 2 diabetes. Contributing factors to the increases in obesity include a decline in positive health behaviors, such as making healthy dietary choices, engaging in physical activity, and limiting sedentary behaviors. Family and physical environmental contextual factors related to health behaviors are increasingly the focus of health behavior interventions in line with the bioecological model that encourages a system-focused perspective on understanding health behavior influences. Physical environmental characteristics, such as home and neighborhood characteristics and resources, provide the tangible means to support health behaviors and are important contextual variables to consider that may increase intervention effectiveness. Therefore, the current review seeks to highlight the importance of investigating influences of behavior beyond individual characteristics in understanding factors related to the risk of developing metabolic syndrome and type 2 diabetes in youth at high risk for developing chronic disease. The current study reviews the non-intervention literature on family and physical environmental factors related to health behaviors (i.e., diet, physical activity, and sedentary behavior) in youth who are considered to be at-risk for developing metabolic syndrome and type 2 diabetes. Results on 38 published articles of diet, physical activity, and sedentary behaviors showed support for the role of parenting and physical environmental factors, particularly parental monitoring and neighborhood context, such as social cohesion, as they relate to health behaviors in high-risk youth. Implications and recommendations for future research are discussed.

    Full Text Available Positive psychological constructs have been given increasing attention in research on the coping resources of cancer-related distresses. However, little research is available on posttraumatic stress disorder (PTSD in patients with hematological malignancies. The purposes of this study were to assess the prevalence of PTSD symptoms and to explore the associations of perceived social support (PSS, hope, optimism and resilience with PTSD symptoms among Chinese patients with hematological malignancies.A cross-sectional study was conducted during the period from July 2013 through April 2014. A total of 225 inpatients with hematological malignancies, which were eligible for the study, completed the Post-traumatic Stress Checklist-Civilian Version, Multidimensional Scale of Perceived Social Support, Adult Hope Scale, Life Orientation Scale-Revised, and Resilience Scale. Hierarchical regression analysis was performed to explore the correlates of PTSD symptoms.Overall, the prevalence of PTSD symptoms was 10.7%. Initially, PSS was negatively associated with PTSD symptoms (β = -0.248, P < 0.01. However, when positive psychological variables were added, optimism was negatively associated with PTSD symptoms (β = -0.452, P < 0.01, and gender had a significant effect on PTSD symptoms. Women were more vulnerable to these symptoms than men (β = 0.123, P < 0.05. When the analysis was performed separately by gender, only optimism showed a significantly negative association with PTSD symptoms in both men (β = -0.389, P < 0.01 and women (β = -0.493, P < 0.01.Some patients with hematological malignancies suffer from PTSD symptoms. The positive effects of PSS and optimism on PTSD symptoms suggest that an integrated approach to psychosocial intervention from both external and internal perspectives could have practical significance. Gender difference should be considered in developing potential interventions in reducing cancer-related PTSD symptoms.

    INTRODUCTION: Diabetes mellitus is one of the most common diseases encountered in clinical practice. Diabetic nephropathy is a common consequence of long-standing diabetes mellitus; microalbuminuria (MA) is considered an early stage of diabetic nephropathy. OBJECTIVES: To determine the prevalence of miciroalbuminuria in diabetic patients and factors associated with MA. MATERIALS AND METHODS: This cross-sectional study was conducted in the diabetic clinic of the primary health center of the National Guard Hospital. Diabetes type 2 patients between the ages of 20–60 years who attended the clinic in 2012 were included in this study. Data were collected by reviewing medical records for demographic and disease-related variables. MA was detected by measuring the albumin to creatinine ratio, and MA was diagnosed if this ratio was between 30 and 300 mg/g on two occasions. RESULTS: MA was found in 37.4% of the sample and the rate was significantly higher among females (P < 0.027). MA was positively related to body mass index (BMI) (P < 0.002), the presence of hypertension (P < 0.000), duration of diabetes (P < 0.000), glycated hemoglobin (P < 0.000), fasting plasma glucose (P < 0.000), and low-density lipoprotein (LDL) (P < 0.043). No statistically significant correlation was found between MA and age, creatinine level, high-density lipoprotein, and triglyceride. CONCLUSION: The prevalence of MA in patients with diabetes in this study was high. The study suggests the need to screen for MA early, and the active management of modifiable risk factors, in particular, hyperglycemia, hypertension, LDL, and BMI, to reduce the burden of future end-stage renal disease.

    Full Text Available BACKGROUND: Studies conducted in high income countries have shown that anaemia is a common medical condition among older people, but such data are scarce in Africa. The objectives of this study were to estimate the prevalence, types, risk factors and clinical correlates of anaemia in older people. METHODS: Participants were aged (≥ 50 years recruited from a general population cohort from January 2012 to January 2013. Blood samples were collected for assessing hemoglobin, serum ferritin, serum vitamin B12, serum folate, C-reactive protein, malaria infection and stool samples for assessment of hookworm infection. HIV status was assessed using an algorithm for HIV rapid testing. Questionnaires were used to collect data on sociodemographic characteristics and other risk factors for anaemia. RESULTS: In total, 1449 people participated (response rate 72.3%. The overall prevalence of anaemia was 20.3 % (95% CI 18.2-22.3%, and this was higher for males (24.1%, 95% CI=20.7-27.7% than females (17.5%, 95% CI=15.0-20.1%. In males, the prevalence of anaemia increased rapidly with age almost doubling between 50 and 65 years (p-trend<0.001. Unexplained anaemia was responsible for more than half of all cases (59.7%. Anaemia was independently associated with infections including malaria (OR 3.49, 95% CI 1.78-6.82, HIV (OR 2.17, 1.32-3.57 heavy hookworm infection (OR 3.45, 1.73-6.91, low fruit consumption (OR 1.55, 1.05-2.29 and being unmarried (OR 1.37 , 95% CI 1.01-1.89. However, the odds of anaemia were lower among older people with elevated blood pressure (OR 0.47, 95% CI 0.29-0.77. CONCLUSION: Anaemia control programmes in Uganda should target older people and should include interventions to treat and control hookworms and educational programs on diets that enhance iron absorption. Clinicians should consider screening older people with HIV or malaria for anaemia. Further studies should be done on unexplained anaemia and serum ferritin levels that predict

    The primary purpose of this research was to examine the construct validity of the Child Abuse Potential Inventory by comparing maltreating and high-risk parents' CAP Inventory abuse scores to their behavior during interactions with their children. A second purpose was to determine the degree to which CAP Inventory scores and parenting behavior were related to several known correlates of abuse, as measured by parent and teacher reports. Participants (n = 41) included abusive and high-risk parents and their children referred to a treatment group. Correlational analyses revealed that CAP Inventory scores and observed parenting style yielded highly related findings, supporting construct validity of the CAP Inventory. However, the CAP Inventory and observed behavior index showed a different pattern of relationships to the risk correlates. Implications for assessment of risk status are discussed and recommendations are provided for continued research.

    Novel or changing environments expose animals to diverse stressors that likely require coordinated hormonal and behavioral adaptations. Predicted adaptations to urban environments include attenuated physiological responses to stressors and bolder exploratory behaviors, but few studies to date have evaluated the impact of urban life on codivergence of these hormonal and behavioral traits in natural systems. Here, we demonstrate rapid adaptive shifts in both stress physiology and correlated boldness behaviors in a songbird, the dark-eyed junco, following its colonization of a novel urban environment. We compared elevation in corticosterone (CORT) in response to handling and flight initiation distances in birds from a recently established urban population in San Diego, California to birds from a nearby wildland population in the species' ancestral montane breeding range. We also measured CORT and exploratory behavior in birds raised from early life in a captive common garden study. We found persistent population differences for both reduced CORT responses and bolder exploratory behavior in birds from the colonist population, as well as significant negative covariation between maximum CORT and exploratory behavior. Although early developmental effects cannot be ruled out, these results suggest contemporary adaptive evolution of correlated hormonal and behavioral traits associated with colonization of an urban habitat.

    Full Text Available INTRODUCTION: Obesity is a worldwide public health issue. Since the epidemiological behaviour of this disease is not well established in our country, the purpose of this study was to determinate its prevalence in the Maracaibo City, Zulia State- Venezuela. MATERIALS AND METHODS: A cross-sectional study was undertaken using the data set from the Maracaibo City Metabolic Syndrome Prevalence Study. The sample consists of 2108 individuals from both genders and randomly selected: 1119 (53.09% women and 989 (46.91% men. The participants were interrogated for a complete clinical history and anthropometric measurements. To classify obesity, the WHO criteria for Body Mass Index (BMI, and Waist Circumference (WC from the IDF/NHLBI/AHA/WHF/IAS/IASO-2009 (IDF-2009 and ATPIII statements were applied. RESULTS: For BMI, obesity had an overall prevalence of 33.3% (n = 701, and according to gender women had 32.4% (n = 363 and men had 34.2% (n = 338. Overweight had a prevalence of 34.8% (n = 733, Normal weight had 29.8% (n = 629, and Underweight had 2.1% (n = 45. Adding Obesity and Overweight results, the prevalence of elevated BMI (>25 Kg/m(2 was 68.1%. Using the IDF-2009 WC's cut-off, Obesity had 74.2% prevalence, compared to 51.7% using the ATPIII parameters. CONCLUSIONS: These results show a high prevalence of abdominal obesity in our locality defined by the WHO, IDF-2009 and ATPIII criteria, which were not designed for Latin-American populations. We suggest further investigation to estimate the proper values according to ethnicity, genetic background and sociocultural aspects.

  3. Cluster-based statistics for brain connectivity in correlation with behavioral measures.

    Full Text Available Graph theoretical approaches have successfully revealed abnormality in brain connectivity, in particular, for contrasting patients from healthy controls. Besides the group comparison analysis, a correlational study is also challenging. In studies with patients, for example, finding brain connections that indeed deepen specific symptoms is interesting. The correlational study is also beneficial since it does not require controls, which are often difficult to find, especially for old-age patients with cognitive impairment where controls could also have cognitive deficits due to normal ageing. However, one of the major difficulties in such correlational studies is too conservative multiple comparison correction. In this paper, we propose a novel method for identifying brain connections that are correlated with a specific cognitive behavior by employing cluster-based statistics, which is less conservative than other methods, such as Bonferroni correction, false discovery rate procedure, and extreme statistics. Our method is based on the insight that multiple brain connections, rather than a single connection, are responsible for abnormal behaviors. Given brain connectivity data, we first compute a partial correlation coefficient between every edge and the behavioral measure. Then we group together neighboring connections with strong correlation into clusters and calculate their maximum sizes. This procedure is repeated for randomly permuted assignments of behavioral measures. Significance levels of the identified sub-networks are estimated from the null distribution of the cluster sizes. This method is independent of network construction methods: either structural or functional network can be used in association with any behavioral measures. We further demonstrated the efficacy of our method using patients with subcortical vascular cognitive impairment. We identified sub-networks that are correlated with the disease severity by exploiting diffusion

    Full Text Available Background The polycystic ovary syndrome (PCOS is one of the most common endocrine disorders in women at childbearing age. Metabolic syndrome is present from 28% to 46% of patients with PCOS. Non-alcoholic fatty liver disease (NAFLD is considered the hepatic expression of metabolic syndrome. There are few published studies that correlate PCOS and NAFLD. Objective To determine the prevalence of NAFLD and metabolic syndrome in patients with PCOS, and to verify if there is a correlation between NAFLD and metabolic syndrome in this population. Methods Study developed at Gynecology Department of Clinical Hospital of Federal University of Parana (UFPR. The sessions were conducted from April 2008 to January 2009. One hundred and thirty-one patients joined the analysis; 101 were diagnosed with PCOS and 30 formed the control group. We subdivided the PCOS patients into two subgroups: PCOS+NAFLD and PCOS. All the patients were submitted to hepatic sonography. For hepatoestheatosis screening, hepatic ecotexture was compared do spleen’s. For diagnosis of metabolic syndrome, we adopted the National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATP III criteria, as well as the criteria proposed by International Diabetes Federation. Statistical analysis were performed with t of student and U of Mann-Whitney test for means and chi square for proportions. Results At PCOS group, NAFLD was present in 23.8% of the population. At control group, it represented 3.3%, with statistical significance (P=0.01. Metabolic syndrome, by NCEP/ATP III criteria, was diagnosed in 32.7% of the women with PCOS and in 26.6% of the women at control group (no statistical difference, P=0.5. At PCOS+DHGNA subgroup, age, weight, BMI, abdominal circumference and glucose tolerance test results were higher when compared to PCOS group (P<0.01. Metabolic syndrome by NCEP/ATPIII criteria was present in 75% and by International Diabetes Federation criteria in 95.8% of women with

    In a sample of 97 healthy Dutch female university students, women with greater finger tactile sensitivity (von Frey-type filaments) engaged more in partnered (but not solitary masturbation) sexual behavior. Orgasmic responses in the past 30 days were not correlated with finger sensitivity. Results are discussed in terms of differences between different sexual behaviors, as well as susceptibility to reinforcement, and psychoanalytic views of conversion hysteria.

    The main goal of this research is to study the relationship between parents' religious behavior, emotional relations inside family, and self-actualization of male and female high school students of district 2 in Kerman city. Research method is descriptive and of correlative type. Questionnaires of parent's religious behavior, emotional relations inside family, and students' self-actualization were used in the research. After collecting questionnaires, data were analyzed by SPSS, MINITAB, and EXCEL software. The sample volume in the research has been 309 students and their parents, and the sampling method was in the form of classification and then in the form of cluster in two stages. 1.29 % of students had a low self-actualization, 17.15 % had average, and 81.55 % of them had high self-actualization. Also the results showed that 9.4 % of emotional relations in families were undesirable, 55.3 % were relatively desirable, and 35.3 % were desirable. Moreover, 2.27 % of parents' religious behavior was inappropriate, 29.13 % was relatively appropriate, and 68.61 % was appropriate. The main results of the research are as follows: (1) There is a significant positive correlation between parents' religious behavior and emotional relations inside students' family. (2) There is not any significant correlational between parents' religious behavior and students' self-actualization. (3) There is a significant positive correlation between emotional relations inside family and students' self-actualization.

    Relu Cocoş

    Full Text Available Wilson's disease is an autosomal recessive disorder caused by more than 500 mutations in ATP7B gene presenting considerably clinical manifestations heterogeneity even in patients with a particular mutation. Previous findings suggested a potential role of additional genetic modifiers and environment factors on phenotypic expression among the affected patients. We conducted clinical and genetic investigations to perform genotype-phenotype correlation in two large families living in a socio-culturally isolated community with the highest prevalence of Wilson's disease ever reported of 1 ∶ 1130. Sequencing of ATP7B gene in seven affected individuals and 43 family members identified a common compound heterozygous genotype, H1069Q/M769H-fs, in five symptomatic and two asymptomatic patients and detected the presence of two out of seven identified single nucleotide polymorphisms in all affected patients. Symptomatic patients had similar clinical phenotype and age at onset (18 ± 1 years showing dysarthria and dysphagia as common clinical features at the time of diagnosis. Moreover, all symptomatic patients presented Kayser-Fleischer rings and lack of dystonia accompanied by unfavourable clinical outcomes. Our findings add value for understanding of genotype-phenotype correlations in Wilson's disease based on a multifamily study in an isolated population with high extent of genetic and environmental homogeneity as opposed to majority of reports. We observed an equal influence of presumed other genetic modifiers and environmental factors on clinical presentation and age at onset of Wilson's disease in patients with a particular genotype. These data provide valuable inferences that could be applied for predicting clinical management in asymptomatic patients in such communities.

    The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association [APA], 2013) modified the diagnostic criteria for posttraumatic stress disorder (PTSD), including expanding the scope of dysfunctional, posttrauma changes in belief (symptoms D2-persistent negative beliefs and expectations about oneself or the world, and D3-persistent distorted blame of self or others for the cause or consequences of the traumatic event). D2 and D3 were investigated using a national sample of U.S. adults (N = 2,498) recruited from an online panel. The prevalence of D2 and D3 was substantially higher among those with lifetime PTSD than among trauma-exposed individuals without lifetime PTSD (D2: 74.6% vs 23.9%; D3: 80.6% vs 35.7%). In multivariate analyses, the strongest associates of D2 were interpersonal assault (OR = 2.39), witnessing interpersonal assault (OR = 1.63), gender (female, OR = 2.11), and number of reported traumatic events (OR = 1.88). The strongest correlates of D3 were interpersonal assault (OR = 3.08), witnessing interpersonal assault (OR = 1.57), gender (female, OR = 2.30), and number of reported traumatic events (OR = 1.91). The findings suggested the expanded cognitive symptoms in the DSM-5 diagnostic criteria better capture the cognitive complexity of PTSD than those of the DSM-IV.

    Full Text Available BACKGROUND: Although poor maternal mental health is a major public health problem, with detrimental effects on the individual, her children and society, information on its correlates in low-income countries is sparse. AIMS: This study investigates the prevalence of common mental disorders (CMD among at-risk mothers, and explores its associations with sociodemographic factors. METHODS: This population-based survey of mothers of children aged 0-36 months used the 14-item Shona Symptom Questionnaire (SSQ. Mothers whose response was "yes" to 8 or more items on the scale were defined as "at risk of CMD." RESULTS: Of the 1,922 mothers (15-48 years, 28.8% were at risk of CMD. Risk of CMD was associated with verbal abuse, physical abuse, a partner who did not help with the care of the child, being in a polygamous relationship, a partner with low levels of education, and a partner who smoked cigarettes. Cohabiting appeared to be protective. CONCLUSIONS: Taken together, our results indicate the significance of the quality of relations with one's partner in shaping maternal mental health. The high proportion of mothers who are at risk of CMD emphasizes the importance of developing evidence-based mental health programmes as part of the care package aimed at improving maternal well-being in Tanzania and other similar settings.

    We sought to determine the extent to which the geographic variation in the complications of type 1 diabetes (T1D) may reflect the socioeconomic status (SES) conditions and health care performance (HCP) of countries around the world. The World Health Organization (WHO) DiaMond complications study (DiaComp) is a multinational, cross-sectional study of complications in T1D. Information on complications was identified for 892 subjects from 14 clinical centers in 12 countries. All participants were diagnosed with diabetes in childhood (management practices and health care costs. Country-specific indicators of social and economic development were also linked to the complications data. Both diabetes complications and economic and health care factors vary widely across the DiaComp centers. Health system performance, as measured by disability adjusted life expectancy (DALE), gross national investment (GNI) per capita and purchasing power all showed strong consistent correlations with complications, and significant independent associations with complication prevalence after controlling for HbA1c and hypertension. In conclusion, health system performance, social distribution of wealth and purchasing power may play important roles in explaining the geographic variation of diabetes complications.

    Full Text Available Abstract Background Understanding the correlates of dietary intake is necessary in order to effectively promote healthy dietary behavior among children and adolescents. A literature review was conducted on the correlates of the following categories of dietary intake in children and adolescents: Fruit, Juice and Vegetable Consumption, Fat in Diet, Total Energy Intake, Sugar Snacking, Sweetened Beverage Consumption, Dietary Fiber, Other Healthy Dietary Consumption, and Other Less Healthy Dietary Consumption in children and adolescents. Methods Cross-sectional and prospective studies were identified from PubMed, PsycINFO and PsycArticles by using a combination of search terms. Quantitative research examining determinants of dietary intake among children and adolescents aged 3–18 years were included. The selection and review process yielded information on country, study design, population, instrument used for measuring intake, and quality of research study. Results Seventy-seven articles were included. Many potential correlates have been studied among children and adolescents. However, for many hypothesized correlates substantial evidence is lacking due to a dearth of research. The correlates best supported by the literature are: perceived modeling, dietary intentions, norms, liking and preferences. Perceived modeling and dietary intentions have the most consistent and positive associations with eating behavior. Norms, liking, and preferences were also consistently and positively related to eating behavior in children and adolescents. Availability, knowledge, outcome expectations, self-efficacy and social support did not show consistent relationships across dietary outcomes. Conclusion This review examined the correlates of various dietary intake; Fruit, Juice and Vegetable Consumption, Fat in Diet, Total Energy Intake, Sugar Snacking, Sweetened Beverage Consumption, Dietary Fiber, Other Healthy Dietary Consumption, and Other Less Healthy Dietary

    This study had three purposes: (a) to compare the prevalence of boys' and girls' gender-atypical behaviors (GABs) in a sample of Chinese school-aged children, (b) to examine the developmental pattern of GABs in Chinese boys and girls over the age range in question (6-12 years), and (c) to test the effects of being an only child on children's GAB expression. Parents of 486 boys and 417 girls completed a Child Play Behavior and Activity Questionnaire (CPBAQ) in regard to their own children, and a demographic information sheet. The frequency distribution for each gender-related behavior was calculated. The associations between sex, age, and only-child status, and CPBAQ scale scores were examined. Although most GABs (by their very nature) were exhibited infrequently in Chinese children, it was found that girls displayed GABs more frequently than boys did. The prevalence of GABs rose for girls as they grew older, but fell slightly for boys. The expressions of GABs in only children did not differ from that in children with siblings. Possible effects of Chinese culture (including the current only-child policy) on children's GABs are discussed.

    Rapid eye movement sleep behavior disorder (RBD) is thought to be one of the most frequent preceding symptoms of Parkinson's disease (PD). However, the prevalence of RBD in PD stated in the published studies is still inconsistent. We conducted a meta and meta-regression analysis in this paper to estimate the pooled prevalence. We searched the electronic databases of PubMed, ScienceDirect, EMBASE and EBSCO up to June 2016 for related articles. STATA 12.0 statistics software was used to calculate the available data from each research. The prevalence of RBD in PD patients in each study was combined to a pooled prevalence with a 95 % confidence interval (CI). Subgroup analysis and meta-regression analysis were performed to search for the causes of the heterogeneity. A total of 28 studies with 6869 PD cases were deemed eligible and included in our meta-analysis based on the inclusion and exclusion criteria. The pooled prevalence of RBD in PD was 42.3 % (95 % CI 37.4-47.1 %). In subgroup analysis and meta-regression analysis, we found that the important causes of heterogeneity were the diagnosis criteria of RBD and age of PD patients (P = 0.016, P = 0.019, respectively). The results indicate that nearly half of the PD patients are suffering from RBD. Older age and longer duration are risk factors for RBD in PD. We can use the minimal diagnosis criteria for RBD according to the International Classification of Sleep Disorders to diagnose RBD patients in our daily work if polysomnography is not necessary.

    In order to efficiently direct efforts and resources required for the prevention of HIV and other sexually transmitted infection among men who have sex with men (MSM) in Israel, it is necessary to define their particular behaviors, estimate their size, and asses the HIV-burden. This cross-sectional study included a sub-sample from a random representative National study performed in Israel, which included Jewish males aged 18-44 who completed online anonymous questionnaires regarding their sexual attraction and practices, commercial sex-work, as well as condom and substances' use. Additionally, participants were asked to identify themselves as gay, bisexual, or heterosexual. National estimates regarding prevalence of risk-behaviors and HIV-infection among MSM were based on the Statistical Abstract of Israel and the National HIV Registry, respectively. Of the total sample of 997 men, 11.9% reported lifetime male sex encounters, while 4.5% and 3.7% self-identified as gay or bisexual, respectively. The estimated population of self-identified Jewish gays/bisexuals aged 18-44 in Israel was 94,176, and in Tel-Aviv 33,839. HIV prevalence among MSM was estimated at 0.7% in Israel and 1.0% in Tel-Aviv. MSM were more likely to live in Tel-Aviv, had higher levels of education, and were scored higher on several determinants of sexual risk in comparison to those attracted to women, including early sexual debut, greater number of sexual partners, ever paid/been paid for sex, sexually coerced, and substance use. In conclusion, MSM were involved in greater risk behaviors than those who only had female sex partners. Most MSM were living in Tel-Aviv and their estimated HIV prevalence was 1.0%.

    Full Text Available Mutations in LIPH cause of autosomal recessive woolly hair/hypotrichosis (ARWH, and the 2 missense mutations c.736T>A (p.Cys246Ser and c.742C>A (p.His248Asn are considered prevalent founder mutations for ARWH in the Japanese population. To reveal genotype/phenotype correlations in ARWH cases in Japan and the haplotypes in 14 Japanese patients from 14 unrelated Japanese families. 13 patients had woolly hair, and 1 patient had complete baldness since birth. An LIPH mutation search revealed homozygous c.736T>A mutations in 10 of the patients. Compound heterozygous c.736T>A and c.742C>A mutations were found in 3 of the patients, and homozygous c.742C>A mutation in 1 patient. The phenotype of mild hypotrichosis with woolly hair was restricted to the patients with the homozygous c.736T>A mutation. The severe phenotype of complete baldness was seen in only 1 patient with homozygous c.742C>A. Haplotype analysis revealed that the alleles containing the LIPH c.736T>A mutation had a haplotype identical to that reported previously, although 4 alleles out of 5 chromosomes containing the LIPH c.742C>A mutation had a different haplotype from the previously reported founder allele. These alleles with c.742C>A are thought to be the third founder LIPH mutation causing ARWH. To accurately determine the prevalence of the founder mutations, we investigated allele frequencies of those mutations in 819 Japanese controls. Heterozygous c.736T>A mutations were found in 13 controls (allele frequency: 0.0079; carrier rate: 0.016, and heterozygous c.742C>A mutations were found in 2 controls (allele frequency: 0.0012; carrier rate: 0.0024. In conclusion, this study confirms the more accurate allele frequencies of the pathogenic founder mutations of LIPH and shows that there is a third founder mutation in Japan. In addition, the present findings suggest that the mutation patterns of LIPH might be associated with hypotrichosis severity in ARWH.

    Full Text Available Christine A Cooper, Armon Jadidian, Michelle Paggi, Janet Romrell, Michael S Okun, et alDepartment of Neurology, University of Florida, Gainesville, FL, USAAbstract: This study investigates the prevalence and demographic characteristics of hypersexuality in Parkinson’s disease (PD. Impulse control disorders in PD patients have been associated with dopamine agonist therapy. Moreover, hypersexuality and pathological gambling have been associated with males, while females may be inherently thought to be more likely to participate in compulsive shopping and binge-eating behaviors. In this study, a screening mail-in survey was sent to all PD patients at a single Movement Disorders Center. One  hundred forty one of 400 (35.3% research packets were returned completed. Fifteen of 141 patients met initial screening criteria for hypersexual behavior. After detailed interview, only 6/141 (4.3% of PD patients met criteria for pathologic hypersexual behavior. These behaviors included: compulsive masturbation, prostitution, and paraphilias. Patients with a younger age of PD onset were more likely to exhibit hypersexual behavior. Unlike previous report, no significant association was found between hypersexuality and gender or dopamine agonist use. Rather, this study suggests that physicians should be vigilant for hypersexual behavior in all PD patients, regardless of gender and PD medication regimen. Ultimately, given the innate sensitivity of the topic and survey limitations, it is very likely that hypersexual behavior in our cohort, as it is in the general PD population, has been under-reported.Keywords: Parkinson’s disease, hypersexuality, impulsive behavior, dopamine agonists

  1. Form factor approach to the asymptotic behavior of correlation functions in critical models

    CERN Document Server

    Kitanine, N; Maillet, J M; Slavnov, N A; Terras, V

    2011-01-01

    We propose a form factor approach for the computation of the large distance asymptotic behavior of correlation functions in quantum critical (integrable) models. In the large distance regime we reduce the summation over all excited states to one over the particle/hole excitations lying on the Fermi surface in the thermodynamic limit. We compute these sums, over the so-called critical form factors, exactly. Thus we obtain the leading large distance behavior of each oscillating harmonic of the correlation function asymptotic expansion, including the corresponding amplitudes. Our method is applicable to a wide variety of integrable models and yields precisely the results stemming from the Luttinger liquid approach, the conformal field theory predictions and our previous analysis of the correlation functions from their multiple integral representations. We argue that our scheme applies to a general class of non-integrable quantum critical models as well.

    Individuals with fragile X syndrome (FXS) exhibit frontal lobe-associated cognitive and behavioral deficits, including impaired general cognitive abilities, perseverative behaviors, and social difficulties. Neural signals related to these functions are communicated through frontostriatal circuits, which connect with distinct regions of the caudate nucleus (CN). Enlargement of the CN is the most robust and reproduced neuroanatomical abnormality in FXS, but very little is known on how this affects behavioral/cognitive outcomes in this condition. Here, we investigated topography within focal regions of the CN associated with prefrontal circuitry and its link with aberrant behavior and intellect in FXS. Imaging data were acquired from 48 individuals with FXS, 28 IQ-matched controls without FXS (IQ-CTL), and 36 typically developing controls (TD-CTL). Of the total participant count, cognitive and behavioral assessment data were obtained from 44 individuals with FXS and 27 participants in the IQ-CTL group. CN volume and topography were compared between groups. Correlations were performed between CN topography and cognitive as well as behavioral measures within FXS and IQ-CTL groups. As expected, the FXS group had larger CN compared with both IQ-CTL and TD-CTL groups. Correlations between focal CN topography and frontal lobe-associated cognitive and behavioral deficits in the FXS group supported the hypothesis that CN enlargement is related to abnormal orbitofrontal-caudate and dorsolateral-caudate circuitry in FXS. These findings deepen our understanding of neuroanatomical mechanisms underlying cognitive-behavioral problems in FXS and hold promise for informing future behavioral and psychopharmacological interventions targeting specific neural pathways.

    We describe a protocol to image the complex axonal branching structure of identified mechanosensory neurons in Drosophila, combined with a behavioral assay to evaluate the functional output of the neuron. The stimulation of identified mechanosensory neurons in live animals produces a stereotyped grooming reflex. The mechanosensory axonal arbor within the CNS is subsequently labeled with a lipophilic fluorescent dye and imaged by fluorescence microscopy. The behavioral output can therefore be correlated to the axonal morphology of the stimulated neuron in the same animal. Combining this protocol with genetic analysis provides a powerful tool for identifying the roles of molecules involved in different aspects of hard-wired neural circuit formation underlying an innate behavior. From behavioral analysis to axonal imaging, the protocol takes 4 d.

    The study purpose was to analyze current daily and current daily nicotine-containing electronic cigarette (EC) use in the European Union (EU). Special Eurobarometer 429, a cross-sectional survey performed in a representative sample of 28 member states of the EU in November and December of 2014, was analyzed. The prevalence of current daily and current daily nicotine-containing EC use was 1.08% (95% CI 0.95-1.20%) and 1.00% (95% CI 0.88-1.12%), respectively, and was mainly observed in current and former smokers. Minimal current daily (0.08%, 95% CI 0.03-0.12%) and current daily nicotine-containing EC use (0.04%, 95% CI 0.01-0.08%) was observed among never smokers. Smoking cessation with the help of ECs was reported by 47.12% (95% CI 41.28-52.96%) of current daily and 49.14% (95% CI 43.12-55.17%) of current daily nicotine-containing EC users. Additionally, 33.18% (95% CI 27.67-38.69%) and 31.40% (95% CI 25.80-36.99%) reported reduction in smoking consumption, respectively. The strongest correlates of daily EC use were being current and former smokers. In the EU in late 2014, current daily EC use was predominantly observed in current and former smokers and was associated with high self-reported rates of smoking cessation and reduction. Current daily EC use by never smokers was extremely infrequent.

    The article estimates the prevalence and sociodemographic correlates of intimate partner violence (IPV) by type and severity in population-based samples from three countries of the former Soviet Union (fSU). The article utilized nationally representative data from the Demographic and Health Surveys (DHS) conducted in Azerbaijan (2006), Moldova (2005), and Ukraine (2007). Respondents were selected using stratified multistage cluster sampling. The sample included ever-married (or cohabitating) females of reproductive age (15-49 years old); weighted sample n = 3,847 in Azerbaijan, n = 4,321 in Moldova, and n = 2,355 in Ukraine. The analysis used multinomial survey logistic regression adjusting for the sampling design and sampling weights. Ten percent of ever-partnered women in Azerbaijan and Ukraine and 20% in Moldova ever experienced physical IPV (without sexual) from their most recent husband or cohabitating partner; 3% of women in Azerbaijan and Ukraine and 5% in Moldova experienced sexual IPV (with or without physical), and 2% of women in Azerbaijan, 3% in Ukraine, and 6% in Moldova experienced violence resulting in severe physical injuries from their most recent partner. In all three countries physical, sexual, and injurious IPV was higher among formerly married women. Compared to women with above secondary education, women with secondary education or below demonstrated higher risk for physical IPV (in Moldova and Ukraine), sexual IPV in Moldova, and injurious IPV in all three countries. Poor socioeconomic status-as indicated by low household wealth status in Azerbaijan and partner's unemployment in Moldova and Ukraine-was significantly associated with higher risk for physical and injurious IPV. In Moldova and Ukraine partners' low level of education was associated with higher risk for sexual IPV. The article demonstrates that experiences and factors associated with IPV are diverse and context specific. The findings may be helpful in targeting interventions to

    Full Text Available Abstract Background Alteration of natural or historical aquatic flows can have unintended consequences for regions where waterborne diseases are endemic and where the epidemiologic implications of such change are poorly understood. The implementation of flood protection measures for a portion of an intensely monitored population in Matlab, Bangladesh, allows us to examine whether cholera outcomes respond positively or negatively to measures designed to control river flooding. Methods Using a zero inflated negative binomial model, we examine how selected covariates can simultaneously account for household clusters reporting no cholera from those with positive counts as well as distinguishing residential areas with low counts from areas with high cholera counts. Our goal is to examine how residence within or outside a flood protected area interacts with the probability of cholera presence and the effect of flood protection on the magnitude of cholera prevalence. Results In Matlab, living in a household that is protected from annual monsoon flooding appears to have no significant effect on whether the household experiences cholera, net of other covariates. However, counter-intuitively, among households where cholera is reported, living within the flood protected region significantly increases the number of cholera cases. Conclusions The construction of dams or other water impoundment strategies for economic or social motives can have profound and unanticipated consequences for waterborne disease. Our results indicate that the construction of a flood control structure in rural Bangladesh is correlated with an increase in cholera cases for residents protected from annual monsoon flooding. Such a finding requires attention from both the health community and from governments and non-governmental organizations involved in ongoing water management schemes.

    Background Peru has a concentrated HIV epidemic in which men who have sex with men are particularly vulnerable. We describe the lifetime prevalence of same-sex sexual contact and associated risk behaviors of men in Peru's general population, regardless of their sexual identity. Methods and Results A probability sample of males from low-income households in three Peruvian cities completed an epidemiologic survey addressing their sexual risk behavior, including sex with other men. Serum was tested for HSV-2, HIV, and syphilis. Urine was tested for chlamydia and gonorrhea. A total of 2,271 18–30 year old men and women were contacted, of whom 1,645 (72.4%) agreed to participate in the study. Among the sexually experienced men surveyed, 15.2% (85/558, 95% CI: 12.2%–18.2%) reported a history of sex with other men. Men ever reporting sex with men (MESM) had a lower educational level, had greater numbers of sex partners, and were more likely to engage in risk behaviors including unprotected sex with casual partners, paying for or providing compensated sex, and using illegal drugs. MESM were also more likely to have had previous STI symptoms or a prior STI diagnosis, and had a greater prevalence of HSV-2 seropositivity. Conclusions Many low-income Peruvian men have engaged in same-sex sexual contact and maintain greater behavioral and biological risk factors for HIV/STI transmission than non-MESM. Improved surveillance strategies for HIV and STIs among MESM are necessary to better understand the epidemiology of HIV in Latin America and to prevent its further spread. PMID:17712426

    To determine the prevalence of HIV and correlates of HIV infection among female sex workers (FSWs) in Soc Trang province, Vietnam, a survey of 406 FSWs in Soc Trang province was conducted between May and August, 2003. The participants were interviewed, using a standardized interview, to obtain information about socio-demographic and behavioral characteristics, and gynecologic and sexually transmitted infection (STI) history. The prevalence of HIV was 3.3%. An increased risk for HIV was associated with ever using illicit drugs, direct sex work, early sexual debut, age of FSWs, and infection with candidiasis and trichomoniasis. Reduced likelihood of HIV was only associated with withdrawal as a contraceptive method. A strong association of HIV with drug use and candidiasis and trichomoniasis infection among FSWs was found. Needle/syringe exchange, STI treatment, and methadone programs targeting FSWs should be implemented, and should include 100% condom use promotion.

    Sexually transmitted infections are diseases provoking a great social and economic burden as well as health-related problems, and with the aging of society and the extension of life expectancy sexually transmitted infections in the elderly have drawn more attention these days. For the management of sexually transmitted infections in this population, basic epidemiological data need to be established. In this study, 1,804 persons from the general population aged over 60 years visiting health examination centers were tested for syphilis, gonorrhea, and chlamydia, and interviewed about the patterns of sexual behavior of elderly people through questionnaires. The prevalence rates of syphilis, gonorrhea, and chlamydia recorded were 0.222% (4/1804), 0 (none), and 0.776% (14/1804), respectively. The results of the survey showed that the sexual life of the elderly people was currently active, and the sexual behavior of chlamydia patients was distinguished in some characteristics from that of the general participants. Political management to prevent sexually transmitted infections needs to be continued in elderly people as it is in other age groups. More detailed follow-up studies are necessary to determine the incidence and prevalence rates of the diseases in the elderly population in future, and the results of this study are considered to be useful as basic data for such studies.

    Background Little is known of the epidemiology of diabetes among older people in low and middle income countries. We aimed to study and compare prevalence, social patterning, correlates, detection, treatment and control of diabetes among older people in Latin America, India, China and Nigeria. Methods Cross-sectional surveys in 13 catchment area sites in nine countries. Diagnosed diabetes was assessed in all sites through self-reported diagnosis. Undiagnosed diabetes was assessed in seven Latin American sites through fasting blood samples (glucose > = 7mmol/L). Results Total diabetes prevalence in catchment sites in Cuba (prevalence 24.2%, SMR 116), Puerto Rico (43.4%, 197), and urban (27.0%, 125), and rural Mexico (23.7%, 111) already exceeds that in the USA, while that in Venezuela (20.9%, 100) is similar. Diagnosed diabetes prevalence varied very widely, between low prevalences in sites in rural China (0.9%), rural India (6.6%) and Nigeria (6.0%). and 32.1% in Puerto Rico, explained mainly by access to health services. Treatment coverage varied substantially between sites. Diabetes control (40 to 61% of those diagnosed) was modest in the Latin American sites where this was studied. Diabetes was independently associated with less education, but more assets. Hypertension, central obesity and hypertriglyceridaemia, but not hypercholesterolaemia were consistently associated with total diabetes. Conclusions Diabetes prevalence is already high in most sites. Identifying undiagnosed cases is essential to quantify population burden, particularly in least developed settings where diagnosis is uncommon. Metabolic risk factors and associated lifestyles may play an important part in aetiology, but this requires confirmation with longitudinal data. Given the high prevalence among older people, more population research is indicated to quantify the impact of diabetes, and to monitor the effect of prevention and health system strengthening on prevalence, treatment and control

    Highlights: • We studied the dynamic wetting behavior of thermally modified wood by wetting models. • We found lower wetting speed of water droplets on thermally modified wood surface. • Dynamic wetting behavior and surface chemical components show a strong correlation. - Abstract: In order to investigate the dynamic wetting behavior of thermally modified wood, Cathay poplar (Populus cathayana Rehd.) and Scots pine (Pinus sylvestris L.) samples were thermally modified in an oven at 160, 180, 200, 220 or 240 °C for 4 h in this study. The dynamic contact angles and droplet volumes of water droplets on modified and unmodified wood surfaces were measured by sessile drop method, and their changing rates (expression index: K value and wetting slope) calculated by wetting models were illustrated for mapping the dynamic wetting process. The surface chemical components were also measured by X-ray photoelectron spectroscopy analysis (XPS), thus the relationship between dynamic wetting behavior and chemical components of thermally modified wood were determined. The results indicated that thermal modification was capable of decreasing the dynamic wettability of wood, expressed in lowing spread and penetration speed of water droplets on wood surfaces. This change was more obvious with the increased heating temperature. The K values varied linearly with the chemical components parameter (mass loss, O/C ratio, and C{sub 1}/C{sub 2} ratio), indicating a strong correlation between dynamic wetting behavior and chemical components of thermally modified wood.

    Neurobehavioral and developmental issues with a broad range of deficits are prominent features of Cornelia de Lange syndrome (CdLS), a disorder due to disruption of the cohesin protein complex. The etiologic relationship of these clinical findings to anatomic abnormalities on neuro-imaging studies has not, however, been established. Anatomic abnormalities in the brain and central nervous system specific to CdLS have been observed, including changes in the white matter, brainstem, and cerebellum. We hypothesize that location and severity of brain abnormalities correlate with clinical phenotype in CdLS, as seen in other developmental disorders. In this study, we retrospectively evaluated brain MRI studies of 15 individuals with CdLS and compared these findings to behavior at the time of the scan. Behavior was assessed using the Aberrant Behavior Checklist (ABC), a validated behavioral assessment tool with several clinical features. Ten of fifteen (67%) of CdLS patients had abnormal findings on brain MRI, including cerebral atrophy, white matter changes, cerebellar hypoplasia, and enlarged ventricles. Other findings included pituitary tumors or cysts, Chiari I malformation and gliosis. Abnormal behavioral scores in more than one behavioral area were seen in all but one patient. All 5 of the 15 (33%) patients with normal structural MRI studies had abnormal ABC scores. All normal ABC scores were noted in only one patient and this was correlated with moderately abnormal MRI changes. Although our cohort is small, our results suggest that abnormal behaviors can exist in individuals with CdLS in the setting of relatively normal structural brain findings. © 2016 Wiley Periodicals, Inc.

  16. Measuring the Prevalence of Problematic Respondent Behaviors among MTurk, Campus, and Community Participants.

    Directory of Open Access Journals (Sweden)

    Elizabeth A Necka

    Full Text Available The reliance on small samples and underpowered studies may undermine the replicability of scientific findings. Large sample sizes may be necessary to achieve adequate statistical power. Crowdsourcing sites such as Amazon's Mechanical Turk (MTurk have been regarded as an economical means for achieving larger samples. Because MTurk participants may engage in behaviors which adversely affect data quality, much recent research has focused on assessing the quality of data obtained from MTurk samples. However, participants from traditional campus- and community-based samples may also engage in behaviors which adversely affect the quality of the data that they provide. We compare an MTurk, campus, and community sample to measure how frequently participants report engaging in problematic respondent behaviors. We report evidence that suggests that participants from all samples engage in problematic respondent behaviors with comparable rates. Because statistical power is influenced by factors beyond sample size, including data integrity, methodological controls must be refined to better identify and diminish the frequency of participant engagement in problematic respondent behaviors.

    Detection of bulk tank milk (BTM) antibodies using ELISA (BTM-ELISA) may constitute an inexpensive test for surveillance of Mycobacterium avium subsp. paratuberculosis (MAP) infection in dairy cattle herds provided that the test is accurate and consistent. The objectives of this study were...... to determine: (a) the correlation between repeated BTM reactions; and (b) the association between the BTM antibody ELISA-level and the within-herd prevalence of antibody-positive cows. Eight BTM samples per herd and approximately four milk samples per lactating cow per herd were collected from each of 108...... Danish Holstein herds over a period of one year. All samples were tested using a commercial indirect ELISA for detection of MAP specific antibodies. The individual cow's results were dichotomised and used to estimate the within-herd antibody prevalence at each test-date. These prevalences were...

    Skipping breakfast has been considered a representative unhealthy behavior, but there is little information about the combined effects of breakfast skipping and other unhealthy health habits, especially smoking. First this cross-sectional study investigated unhealthy behaviors among breakfast skippers, and then examined the impact of the combined association of skipping breakfast and smoking on health. A total of 1,200 adults living in one Japanese community were sent questionnaires to elicit data on age, gender, breakfast-eating frequency, and other lifestyle habits. A total 603 of people returned their questionnaires (response rate: 50.3%), and 493 (230 men and 263 women) questionnaires were considered appropriate for analysis. Smoking rate in men (mean age, 53.7 years) and women (mean age, 50.4 years) was 41.3%, and 9.5%, respectively. Skipping breakfast was more prevalent in people under age 50 years (p breakfast skipping (3.10, 95%CI 1.50-6.39). Other factors included, age younger than 50 years (3.04, 95%CI 1.31-7.06) and poor sleeping quality (2.06, 95%CI 1.00-4.25). After examining the combined impact of skipping breakfast and smoking, the highest odds ratio for a diagnosis of diabetes mellitus was found among those who smoked and skipped breakfast (4.68, 95% CI: 1.46-15.05). Moreover, skipping breakfast among non-smokers showed a high association with perceived stress (2.83, 95% CI: 1.05-7.61). In conclusion, the combined unhealthy behaviors of skipping breakfast and smoking are associated with the prevalence of diabetes mellitus.

    Presenilin mutations are the main cause of familial Alzheimer's disease. So far, more than 160 mutations in the Presenilin 1 gene (PSEN1) and approximately 10 mutations in the homologous Presenilin 2 gene (PSEN2) have been identified. Some PSEN1 mutations are associated with a phenotype fulfilling the clinical criteria of frontotemporal dementia. In PSEN2, T122P and M239V mutations presented with severe behavioral disturbances. We describe an Italian patient with a novel PSEN2 mutation (Y231C) who showed behavioral abnormalities and language impairment as presenting symptoms, with later involvement of other cognitive abilities, particularly of posterior functions.

    This study examined the nature and correlates of hoarding among youth with autism spectrum disorders (ASD). Forty children with ASD and a comorbid anxiety disorder were administered a battery of clinician-administered measures assessing presence of psychiatric disorders and anxiety severity. Parents completed questionnaires related to child hoarding behaviors, social responsiveness, internalizing and externalizing behaviors, and functional impairment. We examined the impact of hoarding behaviors on treatment response in a subsample of twenty-six youth who completed a course of personalized cognitive-behavioral therapy targeting anxiety symptoms. Hoarding symptoms were common and occurred in a clinically significant manner in approximately 25 % of cases. Overall hoarding severity was associated with increased internalizing and anxiety/depressive symptoms, externalizing behavior, and attention problems. Discarding items was associated with internalizing and anxious/depressive symptoms, but acquisition was not. Hoarding decreased following cognitive-behavioral therapy but did not differ between treatment responders and non-responders. These data are among the first to examine hoarding among youth with ASD; implications of study findings and future directions are highlighted.

  2. “Rational” or “Intuitive”: Are Behavioral Biases Correlated Across Stock Market Investors?

    2013-06-01

    Full Text Available Human judgments are systematically affected by various biases and distortions. The main goal of our study is to analyze the effects of five well-documented behavioral biases—namely, the disposition effect, herd behavior, availability heuristic, gambler’s fallacy and hot hand fallacy—on the mechanisms of stock market decision making and, in particular, the correlations between the magnitudes of the biases in the cross-section of market investors. Employing an extensive online survey, we demonstrate that, on average, active capital market investors exhibit moderate degrees of behavioral biases. We then calculate the cross-sectional correlation coefficients between the biases and find that all of them are positive and highly significant for both professional and non-professional investors and for all categories of investors, as classified by their experience levels, genders, and ages. This finding suggests that an investor who is more inclined to employ a certain intuitive decision-making technique will most likely accept other techniques as well. Furthermore, we determine that the correlation coefficients between the biases are higher for more experienced investors and male investors, indicating that these categories of investors are likely to behave more consistently, or, in other words, are more likely to decide for themselves whether to rely on simplifying decision-making techniques in general or to reject all of them. Alternatively, this finding may suggest that these investors develop more sophisticated “adaptive toolboxes”, or collections of heuristics, and apply them more systematically.

    Vitamin D deficiency is common in children with asthma, and it associates with poor asthma control, reduced forced expiratory volume in one second (FEV1) and increased requirement for inhaled corticosteroids (ICS). Cross-sectional studies investigating the prevalence, determinants and clinical correlates of vitamin D deficiency in adults with asthma are lacking. We conducted a multi-centre cross-sectional study in 297 adults with a medical record diagnosis of ICS-treated asthma living in London, UK. Details of potential environmental determinants of vitamin D status, asthma control and medication use were collected by questionnaire; blood samples were taken for analysis of serum 25(OH)D concentration and DNA extraction, and participants underwent measurement of weight, height and fractional exhaled nitric oxide concentration (FeNO), spirometry and sputum induction for determination of lower airway eosinophil counts (n=35 sub-group). Thirty-five single nucleotide polymorphisms (SNP) in 11 vitamin D pathway genes (DBP, DHCR7, RXRA, CYP2R1, CYP27B1, CYP24A1, CYP3A4 CYP27A1, LRP2, CUBN, VDR) were typed using Taqman allelic discrimination assays. Linear regression was used to identify environmental and genetic factors independently associated with serum 25(OH)D concentration, and to determine whether vitamin D status was independently associated with Asthma Control Test (ACT) score, ICS dose, FeNO, forced vital capacity (FVC), FEV1 or lower airway eosinophilia. Mean serum 25(OH)D concentration was 50.6nmol/L (SD 24.9); 162/297 (54.5%) participants were vitamin D deficient (serum 25(OH)D concentration D status was associated with higher body mass index (P=0.014), non-White ethnicity (P=0.036), unemployment (P for trend=0.012), lack of vitamin D supplement use (PD status was not found to associate with any marker of asthma control investigated.

    People with an intellectual disability are over-represented in the criminal justice system in many western countries. Identifying accused persons with intellectual disability is important if they are to receive protections available under the law. Accurate diagnosis is also relevant for correctional administrators, probation and parole services, and community services. Diagnosis of intellectual disability must be made on the basis of both cognitive skills (intelligence) and adaptive behavior. In this study, the Kaufman Brief Intelligence Test assessed intelligence, and the Vineland Adaptive Behavior Scales assessed adaptive behavior, through self-report. Tests were administered to 150 offenders, ranging in age from 13 to 53 years, in Australian prisons, juvenile detention centers, legal aid offices, and probation services. Pearson product-moment correlation coefficients calculated among all subtests and between total scores were significant. ROC curve analyses demonstrated that performance on each effectively predicted a standard score of less than 70 on the other one.

  6. Behavioral Correlates of Primates Conservation Status: Intrinsic Vulnerability to Anthropogenic Threats.

    Directory of Open Access Journals (Sweden)

    Amélie Christelle Lootvoet

    Full Text Available Behavioral traits are likely to influence species vulnerability to anthropogenic threats and in consequence, their risk of extinction. Several studies have addressed this question and have highlighted a correlation between reproductive strategies and different viability proxies, such as introduction success and local extinction risk. Yet, very few studies have investigated the effective impact of social behaviour, and evidence regarding global extinction risk remains scant. Here we examined the effects of three main behavioral factors: the group size, the social and reproductive system, and the strength of sexual selection on global extinction risk. Using Primates as biological model, we performed comparative analysis on 93 species. The conservation status as described by the IUCN Red List was considered as a proxy for extinction risk. In addition, we added previously identified intrinsic factors of vulnerability to extinction, and a measure of the strength of the human impact for each species, described by the human footprint. Our analysis highlighted a significant effect of two of the three studied behavioral traits, group size and social and reproductive system. Extinction risk is negatively correlated with mean group size, which may be due to an Allee effect resulting from the difficulties for solitary and monogamous species to find a partner at low densities. Our results also indicate that species with a flexible mating system are less vulnerable. Taking into account these behavioral variables is thus of high importance when establishing conservation plans, particularly when assessing species relative vulnerability.

    Full Text Available The present study focuses on the behavioural factors especially risky sexual behaviours along with the other socio-economic correlates of the high prevalence of STIs and HIV infection in Uganda. The Uganda AIDS Indicator Survey (2011 data is used. The total sample is 16,607 of which 7,122 are men and 9,485 are women. HIV prevalence is high among men (33.4% and women (50.2% with any sexually transmitted infections (STIs or STI symptoms. Women are significantly more vulnerable to any STIs and HIV/AIDS than men. The prevalence of HIV and STIs is much higher among widow, divorced and separated. Drinking alcohol and not using a condom during sex, having two or more sexual partners are the contributing factors to high HIV and STIs prevalence. Awareness of preventive methods and transmission of STIs, and changes in sexual behaviour are required. The difference in the prevalence of STIs and HIV among men and women can be minimised by increasing employment opportunity for women, by securing woman’s sexual right through legal protection and by targeting men’s perception towards women’s sexuality.

  8. Neural correlates to food-related behavior in normal-weight and overweight/obese participants.

    Full Text Available Two thirds of US adults are either obese or overweight and this rate is rising. Although the etiology of obesity is not yet fully understood, neuroimaging studies have demonstrated that the central nervous system has a principal role in regulating eating behavior. In this study, functional magnetic resonance imaging and survey data were evaluated for correlations between food-related problem behaviors and the neural regions underlying responses to visual food cues before and after eating in normal-weight individuals and overweight/obese individuals. In normal-weight individuals, activity in the left amygdala in response to high-calorie food vs. nonfood object cues was positively correlated with impaired satiety scores during fasting, suggesting that those with impaired satiety scores may have an abnormal anticipatory reward response. In overweight/obese individuals, activity in the dorsolateral prefrontal cortex (DLPFC in response to low-calorie food cues was negatively correlated with impaired satiety during fasting, suggesting that individuals scoring lower in satiety impairment were more likely to activate the DLPFC inhibitory system. After eating, activity in both the putamen and the amygdala was positively correlated with impaired satiety scores among obese/overweight participants. While these individuals may volitionally suggest they are full, their functional response to food cues suggests food continues to be salient. These findings suggest brain regions involved in the evaluation of visual food cues may be mediated by satiety-related problems, dependent on calorie content, state of satiation, and body mass index.

    Breakfast skipping is a potentially modifiable behavior that has negative effects on health and is socioeconomically patterned. This study aimed to examine the intrapersonal (health, behavioral, and cognitive) and social factors associated with breakfast skipping. Nonpregnant women (n = 4123) aged 18-45 y from socioeconomically disadvantaged neighborhoods throughout Victoria, Australia, completed a postal questionnaire. Sociodemographic characteristics, diet, physical activity, sedentary behaviors, and cognitive and social factors were assessed by self-report. Breakfast skipping was defined in 2 ways: 1) "rarely/never" eating breakfast (n = 498) and 2) eating breakfast ≤2 d/wk (includes those who rarely/never ate breakfast; n = 865). Poisson regression was used to calculate prevalence ratios and linear trends, adjusting for covariates. The P values for linear trends are reported below. Compared with breakfast consumers, women who reported rarely/never eating breakfast tended to have poorer self-rated health (P-trend breakfast skipping was defined as eating breakfast ≤2 d/wk, additional associations were found for having lower leisure-time physical activity (P-trend = 0.012) and less self-efficacy for eating a healthy diet (P-trend breakfast skipping among women living in socioeconomically disadvantaged areas. Acknowledging the cross-sectional design and need for causal confirmation, programs that aim to promote breakfast consumption in this population group should consider targeting family-related barriers to healthy eating and nutrition knowledge.

    Objective . To examine the prevalence, development, and persistence of sex and drug behaviors that place delinquent youth at risk for human immunodeficiency virus and other sexually transmitted infections (HIV/STI). Methods At the baseline interview, HIV/STI drug and sex risk behaviors were assessed in a stratified random sample of 800 juvenile detainees, aged 10 to 18 years. Participants were re-interviewed approximately 3 years later (mean [SD] follow-up, 3.2 [0.3] years; median follow-up, 3.1 years). The final sample in these analyses (n = 724) includes 316 females and 408 males, 393 African Americans, 198 Hispanics, 131 non-Hispanic whites, and 2 participants who self-identified as “other.” Results Nearly three quarters of youth engaged in one or more unprotected sexual risk behaviors at follow-up. Over 60% had engaged in 10 or more risk behaviors at their baseline interview, and nearly two thirds of them persisted in 10 or more risk behaviors at follow-up. Among youth living in the community, many behaviors were more prevalent at follow-up than at baseline. Among incarcerated youth, the opposite pattern prevailed. Development and persistence of HIV/STI risk behaviors differed by gender, race/ethnicity, and age, even after adjusting for incarceration status. Compared with females, males had higher prevalence rates of many HIV/STI risk behaviors and were more likely to persist in some behaviors and develop new ones. Yet, injection risk behaviors were more prevalent among females than males and were also more likely to develop and persist. Compared with persons younger than 18, persons 18 and older had higher prevalence rates of many HIV/STI risk behaviors at follow-up. Overall, there were few racial and ethnic differences in patterns of HIV/STI risk behaviors; most involved the initiation and persistence of substance use among non-Hispanic whites and Hispanics. Conclusions Because detained youth have a median stay of only 2 weeks, HIV/STI risk behaviors in

    Background Identifying and treating genital infections, including sexually transmitted infections (STI), among newly diagnosed human immunodeficiency virus (HIV)-infected individuals may benefit both public and individual health. We assessed prevalence of genital infections and their correlates among newly diagnosed HIV-infected individuals enrolling in HIV care services in Namibia. Methods Newly diagnosed HIV-infected adults entering HIV care at 2 health facilities in Windhoek, Namibia, were recruited from December 2012 to March 2014. Participants provided behavioral and clinical data including CD4+ T lymphocyte counts. Genital and blood specimens were tested for gonorrhea, Chlamydia, trichomoniasis, Mycoplasma genitalium, syphilis, bacterial vaginosis, and vulvovaginal candidiasis. Results Among 599 adults, 56% were women and 15% reported consistent use of condoms in the past 6 months. The most common infections were bacterial vaginosis (37.2%), trichomoniasis (34.6%) and Chlamydia (14.6%) in women and M. genitalium (11.4%) in men. Correlates for trichomoniasis included being female (adjusted relative risk, [aRR], 7.18; 95% confidence interval [CI], 4.07–12.65), higher education (aRR, 0.58; 95% CI, 0.38–0.89), and lower CD4 cell count (aRR, 1.61; 95% CI, 1.08–2.40). Being female (aRR, 2.39; 95% CI, 1.27–4.50), nonmarried (aRR, 2.30; (95% CI, 1.28–4.14), and having condomless sex (aRR, 2.72; 95% CI, 1.06–7.00) were independently associated with chlamydial infection. Across all infections, female (aRR, 2.31; 95% CI, 1.79–2.98), nonmarried participants (aRR, 1.29; 95% CI, 1.06–1.59), had higher risk to present with any STI, whereas pregnant women (aRR, 1.16, 95% CI 1.03–1.31) were at increased risk of any STI or reproductive tract infection.

    Full Text Available Microalbuminuria is a pre-clinical marker of renal damage in children with sickle cell anaemia and can predict renal failure. Reported prevalence rates increased with age. In Nigeria, burden of disease and prevailing poor health facilities necessitate its screening, determination of prevalence and associated risk factors. It is a cross-sectional as well as descriptive study. Screening microalbuminuria used subjects’ early morning urine. Socio-demographic as well as clinical details were ascertained using semi-structured questionnaires and case files. Associations and statistical relationship of prevalence rates and clinical/epidemiological data were ascertained using chi-squared and multivariate analysis . Two hundred children with sickle cell anaemia (4–17 years in steady state and 200 age/gender-matched controls were enrolled. Prevalence of microalbuminuria was ,respectively, 18.5% and 2.5% for subjects and controls . Microalbuminuria was commoner in females (19.8% than males (17.4% , increased with age , significantly associated with haemoglobin level and hospitalizations (0.001. Subjects had normal renal function. Hospitalizations and haemoglobin levels showed statistical significance on multivariate analysis. Prevalence of microalbuminuria is 18.5%. Age, haemoglobin concentrations, and higher hospitalizations influenced microalbuminuria among subjects. Screening for microalbuminuria should be incorporated in the case management of subjects with identified risk factors.

    Full Text Available A compulsivity spectrum has been hypothesized to exist across Obsessive-Compulsive disorder (OCD, Eating Disorders (ED, substance abuse (SA and binge-drinking (BD. The objective was to examine the validity of this compulsivity spectrum, and differentiate it from an externalizing behaviors dimension, but also to look at hypothesized personality and neural correlates.A community-sample of adolescents (N=1938; mean age 14.5 years, and their parents were recruited via high-schools in 8 European study sites. Data on adolescents' psychiatric symptoms, DSM diagnoses (DAWBA and substance use behaviors (AUDIT and ESPAD were collected through adolescent- and parent-reported questionnaires and interviews. The phenotypic structure of compulsive behaviors was then tested using structural equation modeling. The model was validated using personality variables (NEO-FFI and TCI, and Voxel-Based Morphometry (VBM analysis.Compulsivity symptoms best fit a higher-order two factor model, with ED and OCD loading onto a compulsivity factor, and BD and SA loading onto an externalizing factor, composed also of ADHD and conduct disorder symptoms. The compulsivity construct correlated with neuroticism (r=0.638; p ≤ 0.001, conscientiousness (r=0.171; p ≤ 0.001, and brain gray matter volume in left and right orbitofrontal cortex, right ventral striatum and right dorsolateral prefrontal cortex. The externalizing factor correlated with extraversion (r=0.201; p ≤ 0.001, novelty-seeking (r=0.451; p ≤ 0.001, and negatively with gray matter volume in the left inferior and middle frontal gyri.Results suggest that a compulsivity spectrum exists in an adolescent, preclinical sample and accounts for variance in both OCD and ED, but not substance-related behaviors, and can be differentiated from an externalizing spectrum.

    There has been almost no overlap between behavior genetics and consumer behavior research, despite each field's importance in understanding society. In particular, both have neglected to study genetic influences on consumer adoption and usage of new technologies -- even technologies as important as the mobile phone, now used by 5.8 out of 7.0 billion people on earth. To start filling this gap, we analyzed self-reported mobile phone use, intelligence, and personality traits in two samples of Australian teenaged twins (mean ages 14.2 and 15.6 years), totaling 1,036 individuals. ACE modeling using Mx software showed substantial heritabilities for how often teens make voice calls (.60 and .34 in samples 1 and 2, respectively) and for how often they send text messages (.53 and. 50). Shared family environment - including neighborhood, social class, parental education, and parental income (i.e., the generosity of calling plans that parents can afford for their teens) -- had much weaker effects. Multivariate modeling based on cross-twin, cross-trait correlations showed negative genetic correlations between talking/texting frequency and intelligence (around -.17), and positive genetic correlations between talking/texting frequency and extraversion (about .20 to .40). Our results have implications for assessing the risks of mobile phone use such as radiofrequency field (RF) exposure and driving accidents, for studying adoption and use of other emerging technologies, for understanding the genetic architecture of the cognitive and personality traits that predict consumer behavior, and for challenging the common assumption that consumer behavior is shaped entirely by culture, media, and family environment.

    In Venezuela, members of a social and sexual partner-networking site for MSM completed an online survey regarding sexual behaviors and HIV medical care. Among the 3,175 respondents, self-reported HIV prevalence was 7.8%. Of participants living with HIV, 73.2% reported taking antiretroviral medication and, 56.6% reported complete adherence within the past month. Participants living with HIV were more likely to be older (aOR=1.04 per one-year increase in age, 95% CI: 1.02, 1.06) and diagnosed with an STI in the previous year (aOR=32.35,10.2). These data provide further understanding of the HIV epidemic among MSM in Venezuela, and potential targets for HIV prevention interventions. PMID:26378188

    Full Text Available Abstract Background Despite the increasing prevalence of type 2 diabetes in urban areas, relatively little has been known about its actual prevalence and its associations in rural areas, Vietnam. The purpose of this study was to evaluate the prevalence of impaired fasting glucose (IFG, impaired glucose tolerance (IGT, diabetes and their risk factors in a rural province, Vietnam. Methods A cross–sectional study with a representative sample was designed to estimate the hyperglycemia prevalence, using 75–g oral glucose tolerance test. Potential risk factors for hyperglycemia were analyzed using multinomial logistic regression, taken into account influences of socio–economic status, anthropometric measures, and lifestyle–related factors. Results The age and sex–adjusted prevalence rates (95% CI of isolated IFG, isolated IGT, combined IFG–IGT, and diabetes were 8.7 (7.0–10.5, 4.3 (3.2−5.4, 1.6 (0.9−2.3, and 3.7% (2.7–4.7%, respectively. There were still 73% of diabetic subjects without knowing the condition. Blood pressure, family history of diabetes, obesity–related measures (waist circumference, waist–hip ratio, body fat percentage, and abdominal obesity were the independent risk factors for hyperglycemia (IFG, IGT, and diabetes. Conclusions The prevalence of hyperglycemia in rural areas has not been as sharply increased as that reported in urban cities, Vietnam. Blood pressure and obesity–related measures were the most significant predictors for hyperglycemia level and they can be taken into account in building prognosis models to early detection of diabetes in rural Vietnamese populations.

    Full Text Available Lin Aung Swe,1 Abdul Rashid2 1Beneficial Partner Group, Bahan Township, Myanmar; 2Department of Public Health Medicine, Penang Medical College, Georgetown, Malaysia Background: Myanmar is one of the countries hardest hit by the human immunodeficiency virus (HIV epidemic in Asia. Aim: The objective of the study was to determine HIV prevalence among the female sex workers in major cities in Myanmar and the risk behaviors associated with it. Methods: This cross-sectional study was conducted among female sex workers in major cities in Myanmar. Interviews were conducted by trained research assistants, in private, using a questionnaire. The HIV status of the respondents was asked and confirmed by the blood test reports from the laboratories of the Myanmar National AIDS Programme sexually transmitted infections (STI/acquired immunodeficiency syndrome (AIDS Teams and nongovernmental organizations (NGOs. Results: There were 200 respondents in this study. Out of the 136 participants who were tested for HIV, 25 (18.4% were HIV-positive. Respondents of other ethnic groups than Myanmars and other religions than Buddhist were about six times (odds ratio [OR] 5.9 and five times (OR 4.6, respectively, at higher odds of being HIV-positive. Those who were earning an income of less than 200,000 kyats were almost three times (OR 2.9 at higher odds of being HIV-positive. The difference in the age group was found to be statistically significant (P = 0.001. Respondents who did not have HIV counseling (OR 7.3, who did not use condoms (OR 1.3, and with regular partners who refused the use of condoms (OR 6.0 were at higher odds of being HIV-positive. Conclusion: HIV prevention services should include socioeconomic support programs, and the clients and regular partners of sex workers should also be targeted for behavior-change messages, to reduce condom resistance.

    Full Text Available The prevalence of contact dermatitis (CD in Europe varies between 6.7% and 10.6% depending on the sector of activity. Professional CD (PCD has an important economic impact − 30% of the budget compensation for occupational disease. In Romania, the prevalence of PCD is underestimated, with an even distribution of cases with respect to the allergic or irritative mechanism. A retrospective clinical study was conducted; target population being the patients admitted in Occupational Medicine Clinic Cluj-Napoca between 2003 and 2011. Objectives of study were: specifying the prevalence range of allergic CD (ACD / irritative CD (ICD among occupational/work-related diseases, the distribution of allergic/irritative CD (A/ICD for different sectors of activity and establishing the correlation between atopy and A/ICD. We have applied allergy skin tests - prick (environmental allergens and patch (occupational allergens. Inclusion criteria were: -documented occupational exposure at skin allergens/irritants; -the atopy state; -diagnostic established at discharge. Patients with recurrent chronic urticaria, angioedema, hypereosinophilic syndrome have been excluded. Statistical analysis was done using SPSS software. The study indicated a similar prevalence for A/ICD, with similar distribution. Prevalence above average has been recorded in the metallurgy sector (A/ICD, in health care sector (ACD, respectively, textile industry (ICD. The correlation atopy-ACD has proved to be lower compared to previous reports. Regarding ICD, the diagnostic was confirmed frequently to non-atopic persons. We strongly recommend the compliance with a multidisciplinary protocol for the management of A/ICD, individualized for specific activity sectors or even work stations.

    This study aimed to identify and compare the demographic, health behavior, health status, and social media use correlates of online health-seeking behaviors among men and women. Cross-sectional self-report data were collected from 1,289 Australian adults participating in the Queensland Social Survey. Logistic regression analyses were used to identify the correlates of online health information seeking for men and women. Differences in the strength of the relation of these correlates were tested using equality of regression coefficient tests. For both genders, the two strongest correlates were social media use (men: odds ratio [OR] = 2.57, 95% confidence interval [CI: 1.78, 3.71]; women: OR = 2.93, 95% CI [1.92, 4.45]) and having a university education (men: OR = 3.63, 95% CI [2.37, 5.56]; women: OR = 2.74, 95% CI [1.66, 4.51]). Not being a smoker and being of younger age were also associated with online health information seeking for both men and women. Reporting poor health and the presence of two chronic diseases were positively associated with online health seeking for women only. Correlates of help seeking online among men and women were generally similar, with exception of health status. Results suggest that similar groups of men and women are likely to access health information online for primary prevention purposes, and additionally that women experiencing poor health are more likely to seek health information online than women who are relatively well. These findings are useful for analyzing the potential reach of online health initiatives targeting both men and women.

  20. Schizotypal perceptual aberrations of time: correlation between score, behavior and brain activity.

    Full Text Available A fundamental trait of the human self is its continuum experience of space and time. Perceptual aberrations of this spatial and temporal continuity is a major characteristic of schizophrenia spectrum disturbances--including schizophrenia, schizotypal personality disorder and schizotypy. We have previously found the classical Perceptual Aberration Scale (PAS scores, related to body and space, to be positively correlated with both behavior and temporo-parietal activation in healthy participants performing a task involving self-projection in space. However, not much is known about the relationship between temporal perceptual aberration, behavior and brain activity. To this aim, we composed a temporal Perceptual Aberration Scale (tPAS similar to the traditional PAS. Testing on 170 participants suggested similar performance for PAS and tPAS. We then correlated tPAS and PAS scores to participants' performance and neural activity in a task of self-projection in time. tPAS scores correlated positively with reaction times across task conditions, as did PAS scores. Evoked potential mapping and electrical neuroimaging showed self-projection in time to recruit a network of brain regions at the left anterior temporal cortex, right temporo-parietal junction, and occipito-temporal cortex, and duration of activation in this network positively correlated with tPAS and PAS scores. These data demonstrate that schizotypal perceptual aberrations of both time and space, as reflected by tPAS and PAS scores, are positively correlated with performance and brain activation during self-projection in time in healthy individuals along the schizophrenia spectrum.

    Full Text Available Understanding correlates of physical activity (PA can help inform and improve programs that promote PA among youth. We analyzed data from the 2010 National Youth Physical Activity and Nutrition Study, a representative sample of US students in grades 9–12. Logistic regression was used to examine associations between PA correlates (obesity, physical education classes, sports team participation, attitude toward PA, adult support for PA, and environmental support for PA and participation in daily PA (DPA, vigorous PA (VPA, muscle-strengthening activity (MSA, viewing television (TV, and using computers or video games (C/VG. A positive attitude toward PA and adult support for PA were both associated with increased PA and decreased sedentary behavior. However, among students who lived in neighborhoods that were not safe for PA, a positive attitude toward PA was not associated with increased DPA or decreased sedentary behavior and was less strongly associated with VPA and MSA. Efforts to increase PA among youth should promote a positive attitude toward PA among youth and encourage adult family members to support their efforts to be active. Policies that promote safe neighborhoods may work synergistically with a positive attitude toward PA to increase participation in PA and decrease sedentary behaviors.

    The learned helplessness paradigm has been repeatedly shown to correlate with neurobiological aspects of depression in humans. In this model, rodents are exposed inescapable foot-shock in order to reveal susceptibility to escape deficit, defined as 'learned helplessness' (LH). Few methods are available to probe the neurobiological aspects underlying the differences in susceptibility in the living animal, thus far being limited to studies examining regional neurochemical changes with microdialysis. With the widespread implementation of small animal neuroimaging methods, including positron emission tomography (PET), it is now possible to explore the living brain on a systems level to define regional changes that may correlate with vulnerability to stress. In this study, 12 wild type Sprague-Dawley rats were exposed to 40 minutes of inescapable foot-shock followed by metabolic imaging using 2-deoxy-2[{sup 18}F]fluoro-D-glucose (18-FDG) 1 hour later. The escape test was performed on these rats 48 hours later (to accommodate radiotracer decay), where they were given the opportunity to press a lever to shut off the shock. A region of interest (ROI) analysis was used to investigate potential correlations (Pearson Regression Coefficients) between regional 18-FDG uptake following inescapable shock and subsequent learned helpless behavior (time to finish the test; number of successful lever presses within 20 seconds of shock onset). ROI analysis revealed a significant positive correlation between time to finish and 18-FDG uptake, and a negative correlation between lever presses and uptake, in the medial thalamic area (p=0.033, p=0.036). This ROI included the paraventricular thalamus, mediodorsal thalamus, and the habenula. In an effort to account for possible spillover artifact, the posterior thalamic area (including ventral medial and lateral portions) was also evaluated but did not reveal significant correlations (p=0.870, p=0.897). No other significant

    Non-suicidal self-injury (NSSI) is common among adolescents and linked to many maladaptive outcomes. This study aimed to assess the prevalence and correlates of NSSI among a community sample of New Zealand adolescents. A self-report questionnaire was administered to adolescents at time 1 (N = 1162, mean age = 16.35), and approximately five months later (time 2, N = 830, mean age = 16.49). Prevalence and bivariate correlations were assessed at both time points, and cross-lag correlations using matched data (N = 495, mean age = 16.23). Lifetime history of NSSI was 48.7 % (females 49.4 %, males 48 %). Consistent with previous international research, NSSI was associated with higher Alexithymia, depression, anxiety, bullying, impulsivity, substance abuse, abuse history and sexuality concerns and lower mindfulness, resilience and self-esteem. Cross-lag correlations suggested NSSI is directly (perhaps causally) related to psychological vulnerability in various domains (e.g., increased depression and lower self-esteem), while bullying may be more distal to NSSI, rather than a proximal predictor.

    Objective To estimate the prevalence of elevated blood pressure (EBP) in Chinese children and identify individual and family factors associated with EBP. Methods A nationwide cross-sectional study was conducted in 2010 using stratified cluster sampling. Participants’ blood pressure was measured, and their parents completed a questionnaire on personal and family characteristics. Prevalence and correlates of EBP were assessed. Results Among a total of 24,333 participants, 20.2% of boys and 16.3% of girls had EBP. The prevalence of EBP increased with the ascending trend of waist circumference, Waist-to-height ratio, and body mass index. The adjusted prevalence ratios (aPRs) for obese boys and girls were 2.50 and 2.97, respectively. Fewer urban boys (16.2%) had EBP than rural boys (21.7%). Boys with a family history of hypertension were 12%more likely to have EBP. Children whose mothers received a college education tended to have lower likelihood of EBP;with an aPR was 0.85 among boys and 0.78 among girls. Conclusion EBP is common among obese students and those who have a family history of hypertension. A negative association between mothers’ education levels and EBP risk in children was found.

    As part of a larger randomized controlled trial examining the efficacy of an HIV/AIDS symptom management manual (n = 775), this study examined the prevalence of peripheral neuropathy in HIV-infected individuals at 12 sites in the USA, Puerto Rico, and Africa. Neuropathy was reported by 44% of the sample; however, only 29.4% reported initiating self-care behaviors to address the neuropathy symptoms. Antiretroviral therapy was found to increase the frequency of neuropathy symptoms, with an increased mean intensity of 28%. A principal axis factor analysis with Promax rotation was used to assess the relationships in the frequency of use of the 18 self-care activities for neuropathy, revealing three distinct factors: (i) an interactive self-care factor; (ii) a complementary medicine factor; and (iii) a third factor consisting of the negative health items of smoking, alcohol, and street drugs. The study's results suggest that peripheral neuropathy is a common symptom and the presence of neuropathy is associated with self-care behaviors to ameliorate HIV symptoms. The implications for nursing practice include the assessment and evaluation of nursing interventions related to management strategies for neuropathy.

    Childhood apraxia of speech (CAS) is a neurogenic Speech Sound Disorder whose etiology and neurobiological correlates are still unclear. In the present study, 32 Italian children with idiopathic CAS underwent a comprehensive speech and language, genetic and neuroradiological investigation aimed to gather information on the possible behavioral and neurobiological markers of the disorder. The results revealed four main aggregations of behavioral symptoms that indicate a multi-deficit disorder involving both motor-speech and language competence. Six children presented with chromosomal alterations. The familial aggregation rate for speech and language difficulties and the male to female ratio were both very high in the whole sample, supporting the hypothesis that genetic factors make substantial contribution to the risk of CAS. As expected in accordance with the diagnosis of idiopathic CAS, conventional MRI did not reveal macrostructural pathogenic neuroanatomical abnormalities, suggesting that CAS may be due to brain microstructural alterations.

  10. Correlation between rheological behavior and structure of multi-component polymer systems

    2008-01-01

    Rheological measurement has been an effective method to characterize the structure and properties for multiphase/multi-component polymers, owing to its sensitivity to the structure change of hetero geneous systems. In this article, recent progress in the studies on the morphology/structure and rheological properties of heterogeneous systems is summarized, mainly reporting the findings of the authors and their collaborators, involving the correlation between the morphology and viscoelastic relaxation of LCST-type polymer blends, the microstructure and linear/nonlinear viscoelastic behavior of block copolymers, time scaling of shear-induced crystallization and rheological response of polyolefins, and the relationship between the structure/properties and rheological behavior of filled polymer blends. It is suggested that a thorough understanding of the characteristic rheological response to the morphology/structure evolution of multiphase/multi-component polymers facilitates researchers' optimizing the morphology/structure and ultimate mechanical properties of polymer materials.

    /sup 14/C-2-Deoxyglucose (2DG) was used to investigate changes in the rate of cerebral metabolism in 3 rat models of depressed behavior. The models had already been established in the literature and were induced by injections of alpha-methyl-para-tyrosine, withdrawal from chronic amphetamine, or stress. We verified that exploratory behaviors were depressed in each model and that an antidepressant drug, tranylcypromine, prevented the depressed behavior in each model. 2DG studies revealed that the rate of regional glucose metabolism was elevated bilaterally in the lateral habenula of each of the 3 models. Regional metabolic rates were reduced in each model in the dorsal medial prefrontal cortex, anterior ventral nucleus of the thalamus, and inferior colliculus. Forebrain global metabolic rates were also reduced in each of the models. Tranylcypromine prevented the elevated rate of lateral habenula metabolism seen in each of the models alone but did not significantly affect the rates of global metabolism. Our findings of identical metabolic changes in each of the models indicate that these changes are not idiosyncratic to a particular model; rather, they correlate with a generalizable state of depressed exploratory behavior in rats.

    Introdução: Em Portugal não existem dados atuais sobre tentativas de controlo do peso nem sobre estratégias e motivos na base dessas tentativas na população. Este estudo teve como objectivos determinar a prevalência das tentativas de perda/manutenção do peso e identificar as estratégias comportamentais e os motivos associados, numa amostra representativa da população adulta portuguesa. Material e Métodos: Estudo transversal constituído por 1098 indivíduos adultos. A informação sociodemográfica, os dados antropométricos e as estratégias e motivos associados à perda/manutenção do peso foram recolhidos por entrevista telefónica. Resultados: Cerca de 44% dos adultos portugueses (53% de mulheres e 35% dos homens) estão ativamente a tentar controlar o peso. Salienta-se que 22% das mulheres com peso normal tentam perder peso e que 53% dos homens e 34% das mulheres com peso excessivo não o fazem. Entre os homens, 49% com nível educacional superior estão a tentar controlar o peso versus 32% com nível educacional básico. A estratégia mais frequentemente adoptada para gerir o peso é o consumo regular de hortícolas e os motivos mais referenciados são melhorar a saúde/prevenir doenças e melhorar o bem-estar. Discussão e Conclusão: Mais de metade das mulheres e cerca de um terço dos homens em Portugal estão ativamente a tentar gerir o seu peso, utilizando estratégias comportamentais consistentes com as recomendações de saúde pública. Os motivos de saúde e bem-estar predominam sobre os restantes. Este estudo contribui para o conhecimento da gestão do peso em Portugal, alertando para o desenvolvimento de estratégias de prevenção da obesidade adequadas ao perfil da população.

  14. Promoting the translation of intentions into action by implementation intentions: Behavioral effects and physiological correlates

    2015-07-01

    Full Text Available The present review addresses the physiological correlates of planning effects on behavior. Although intentions to act qualify as predictors of behavior, accumulated evidence indicates that there is a substantial gap between even strong intentions and subsequent action. One effective strategy to reduce this intention-behavior gap is the formation of implementation intentions that specify when, where, and how to act on a given goal in an if-then format (If I encounter situation Y, then I will initiate action Z!. It has been proposed that implementation intentions render the mental representation of the situation highly accessible and establish a strong associative link between the mental representations of the situation and the action. These process assumptions have been examined in behavioral research, and in physiological research, a field that has begun to investigate the temporal dynamics of and brain areas involved in implementation intention effects. In the present review, we first summarize studies on the cognitive processes that are central to the strategic automation of action control by implementation intentions. We then examine studies involving critical samples with impaired self-regulation. Lastly, we review studies that have applied physiological measures such as heart rate, cortisol level, and eye movement, as well as electroencephalography (EEG and functional magnetic resonance imaging (fMRI studies on the neural correlates of implementation intention effects. In support of the assumed processes, implementation intentions increased goal attainment in studies on cognitive processes and in critical samples, modulated brain waves related to perceptual and decision processes, and generated less activity in brain areas associated with effortful action control. In our discussion, we reflect on the status quo of physiological research on implementation intentions, methodological and conceptual issues, related research, and propose future

    Modern video games represent highly advanced virtual reality simulations and often contain virtual violence. In a significant amount of young males, playing video games is a quotidian activity, making it an almost natural behavior. Recordings of brain activation with functional magnetic resonance imaging (fMRI) during gameplay may reflect neuronal correlates of real-life behavior. We recorded 13 experienced gamers (18-26 years; average 14 hrs/week playing) while playing a violent first-person shooter game (a violent computer game played in self-perspective) by means of distortion and dephasing reduced fMRI (3 T; single-shot triple-echo echo-planar imaging [EPI]). Content analysis of the video and sound with 100 ms time resolution achieved relevant behavioral variables. These variables explained significant signal variance across large distributed networks. Occurrence of violent scenes revealed significant neuronal correlates in an event-related design. Activation of dorsal and deactivation of rostral anterior cingulate and amygdala characterized the mid-frontal pattern related to virtual violence. Statistics and effect sizes can be considered large at these areas. Optimized imaging strategies allowed for single-subject and for single-trial analysis with good image quality at basal brain structures. We propose that virtual environments can be used to study neuronal processes involved in semi-naturalistic behavior as determined by content analysis. Importantly, the activation pattern reflects brain-environment interactions rather than stimulus responses as observed in classical experimental designs. We relate our findings to the general discussion on social effects of playing first-person shooter games.

  16. Predicting the Failure Behavior of Textile Composite Laminates by Using a Multi-Scale Correlating Approach

    Deng, Yan; Chen, Xiuhua; Wang, Hai

    2015-12-01

    This paper investigates the elastic and failure behavior of textile composite laminates by using an analytical multi-scale correlating approach. The analyses are performed under the four scale levels, i.e. the laminate scale, representative unit cell (RUC) scale, tow architecture scale and fiber/matrix scale levels. The correlation between different scales is derived based on the continuum mechanics and homogenization method from which the stress and strain fields in multiple scales can be obtained concurrently. Effective modulus and ultimate failure strengths of different textile composite (plain weave, twill weave and satin weave) laminates are predicted solely from the corresponding constituent properties, braid geometrical parameters and lay-up. The damage and failure mechanisms at the constituent level are also determined by the micromechanical failure criteria. All the predicted results compare favorably with available experimental data. Parametric studies are also performed to examine the effect of various mechanical and geometrical parameters on the resulting mechanical properties.

    Emotions and emotion regulation are of special importance in the perception and modulation of pain but the mechanisms underlying this reciprocal relationship remain unclear. The transdiagnostic model provides an approach to explain the link between pain and emotion regarding cognitive and neuronal mechanisms and aims to identify mutual processes, which are relevant for both. Structural and functional imaging studies of pain indicate the involvement of specific cortical and subcortical structures, which also play an important role in emotion regulation. While numerous studies have investigated emotion regulation and their correlates in the central nervous system in pathological states, the research on emotion regulation in pain is still young. The purpose of this review is to provide an overview of experimental and clinical studies of neuronal and behavioral correlates of pain-related emotion regulation. The current transdiagnostic approach may be able to enhance pain relief in the future.

    2014-01-01

    Transgender women (“transwomen”) face a disproportionate HIV disease burden; the odds of being HIV-positive are estimated to be 34.2 times higher for transwomen than the United States adult population. From January 1, 2005 through December 31, 2011, HIV prevention outreach encounters were conducted with 2,136 unique transwomen on the streets and at high-risk venues in Los Angeles County. The outreach encounters were comprised of a low-intensity health education and risk reduction intervention, which included referrals to needed services. The goal of the encounters was to assess the participant's level of substance use and sexual risk behaviors to provide appropriate risk reduction strategies and supplies. The sample evidenced high rates of recent alcohol (57.7%), marijuana (25.6%), and methamphetamine (21.5%) use, lifetime injection drug or illegal hormone use (66.3%), and recent engagement in sex work (73.3%). Multivariate logistic regression analysis revealed that recent methamphetamine (AOR=2.09; p<.001) and/or crack cocaine (AOR=2.19; p=0.010) use, injection drug/hormone use (AOR=1.65; p≤0.001), unprotected anal intercourse during sex work (AOR=2.24; p=0.029), and any non-Hispanic minority racial status were all associated with increased odds of reporting a HIV-positive status. The transwomen encountered via outreach exhibited many risk co-factors for HIV infection and transmission. PMID:24287786

    This study aims to examine the psychopathological profile of non-homicidal sexual offenders (NHSOs) and homicidal sexual offenders (HSOs). Using an incarcerated sample of 96 NHSOs and 74 HSOs in a federal penitentiary in Canada, these offenders are compared in terms of their offending process, maladaptive personality traits, and paraphilic behaviors. A number of cross-tabular and sequential logistic regression analyses are performed. Relative to their counterpart, findings indicate that a higher percentage of HSOs select a victim of choice, report deviant sexual fantasies, mutilate their victim, and admit to their offense upon apprehension, whereas a higher percentage of NHSOs select victims with distinctive characteristics. In addition, a higher percentage of HSOs manifest paranoid, schizotypal, borderline, histrionic, narcissistic, obsessive-compulsive, and impulsive personality traits, and overall odd and eccentric personality traits compared with NHSOs. Similarly, a higher percentage of HSOs engage in exhibitionism, fetishism, frotteurism, homosexual pedophilia, sexual masochism, and partialism compared with NHSO. These findings are discussed with their implications for offender profiling.

    2000-01-01

    The sample for this study consisted of 386 children from six to 59 months of age. The objective was to study the association between wasting and abdominal circumference. Thirteen anthropometric measurements were taken: weight, height or length, crown-rump length, 4 circumferences, 4 skin fold thicknesses, and 2 breadths. Muscle, fat, and total upper arm areas and leg length were calculated. Indices of body proportionality were obtained by dividing the anthropometric variables by height. Height-for-age, weight-for-age, and weight-for-height deficits were 25.9%, 14.4%, and 3.5%, respectively. The smallest and lightest children were those with the highest abdominal circumferences divided by height. According to this study, abdominal circumference for Brazilian children without height-for-age deficit is, on average, 1.2 cm larger than for US children. Using this as a basis, the study calculated that prevalence of weight-for-height deficit would increase from 3.5% to 7.0% by increasing 2 cm in the abdominal circumference. The low prevalence of wasting and the high prevalence of stunting as indicated by several Brazilian studies could be explained partially by larger mean abdominal circumference values.

    strongly related to current depression. CONCLUSIONS: Depression syndromes are frequent in patients with neurocysticercosis. The extent to which organic mechanisms related to brain lesions may underlie the observed mental changes is yet unclear, though the similar sex distribution of patients with and without depression, as well as the above mentioned correlations, provide further evidence of the role played by organic factors in the cause of these syndromes. The results of this study are discussed in the light of the data available for other organic psychiatric disorders.

    2016-01-01

    Full Text Available Introduction: The sense of coherence (SOC has been suggested to be highly applicable concept in the public health area because a strong SOC is stated to decrease the likelihood of perceiving the social environment as stressful. This reduces the susceptibility to the health-damaging effect of chronic stress by lowering the likelihood of repeated negative emotions to stress perception. Materials and Methods: The demographic data and general information of subjects' oral health behaviors such as frequency of cleaning teeth, aids used to clean teeth, and dental attendance were recorded in the self-administered questionnaire. The SOC-related data were obtained using the short version of Antonovsky's SOC scale. The periodontal status was recorded based on the modified World Health Organization 1997 pro forma. Results: The total of 780 respondents comprising 269 (34.5% males and 511 (65.5% females participated in the study. A significant difference was noted among the subjects for socioeconomic status based on gender (P = 0.000. The healthy periodontal status (community periodontal index [CPI] code 0 was observed for 67 (24.9% males and 118 (23.1% females. The overall SOC showed statistically negative correlation with socioeconomic status scale (r = −0.287. The CPI and loss of attachment (periodontal status were significantly and negatively correlated with SOC. Conclusion: The present study concluded that a high level of SOC was associated with good oral health behaviors, periodontal status, and socioeconomic status.

    2013-08-14

    The present study was aimed at identifying potential behavioral and neural correlates of emotional intelligence (EI) by using scalp-recorded Event-Related Potentials (ERPs). EI levels were defined according to both self-report questionnaire and a performance-based test. We identified ERP correlates of emotional processing by comparing ERPs elicited in trials using pleasant, neutral and unpleasant pictures. The effects of these emotion-inducing pictures were then compared across groups with low and high EI levels. Behavioral results revealed a significant valence×EI group interaction effect since valence ratings were lower for unpleasant pictures and higher for pleasant pictures in the high EI group compared with the low EI group. The groups did not differ with respect to neutral picture ratings. The ERP results indicate that participants with high EI exhibited significantly greater mean amplitudes of the P2 (200-300ms post-stimulus) and P3 (310-450ms post-stimulus) ERP components in response to emotional and neutral pictures, at posterior-parietal as well as at frontal scalp locations. This may suggest greater recruitment of resources to process all emotional and non-emotional stimuli at early and late processing stages among individuals with higher EI. The present study also underscores the usefulness of ERP methodology as a sensitive measure for the study of emotional stimuli processing in the research field of EI.

  8. Prevalence and correlates of increased lung/heart ratio of thallium-201 during dipyridamole stress imaging for suspected coronary artery disease

    There is little information concerning the prevalence and clinical correlates of increased pulmonary thallium-201 uptake during dipyridamole thallium-201 stress imaging. Accordingly, the clinical characteristics and quantitative thallium-201 findings were correlated with quantitative lung/heart thallium-201 ratio in 87 patients undergoing dipyridamole thallium-201 stress testing. Nineteen patients (22%) had an elevated ratio (greater than 0.51). These patients were more likely to have had an infarction, to be taking beta blockers, and have a lower rate-pressure product after dipyridamole administration than those with a normal ratio (p less than 0.03). An elevated ratio was associated with a greater likelihood of initial, redistribution and persistent defects, as well as left ventricular cavity dilatation on thallium-201 imaging (p less than 0.05). In addition, the number of myocardial segments demonstrating initial, redistribution and persistent defects was also greater in patients with increased ratios (p less than 0.03). Multivariate analysis demonstrated that the presence of redistribution and left ventricular cavity dilatation were the most significant correlates of lung/heart thallium-201 ratio. It is concluded that the prevalence of increased lung/heart thallium-201 ratio with dipyridamole thallium-201 stress imaging is similar to that seen with exercise stress imaging. As with exercise thallium-201 imaging, increased pulmonary thallium-201 uptake may be a marker of functionally more significant coronary artery disease.

    The aim of this study was to examine neurophysiological and behavioral correlates of cognitive control elicited by a modified flanker task while exercising at low and moderate intensities. A secondary aim was to examine cognitive control processes at several time points during an acute bout of exercise to determine whether cognition is selectively influenced by the duration of exercise. Twenty-seven healthy participants completed a modified version of the Eriksen flanker task while exercising on a cycle ergometer at 40% and 60% VO2 peak and during a no-exercise seated control across three separate days. During task performance, continuous EEG was collected to assess neurocognitive function using the N2 and P3 event-related brain potentials (ERPs). Neurocognitive performance was assessed at 5, 15, and 25min time points during steady-state exercise. Regardless of intensity, behavioral findings revealed impaired accuracy during both exercise conditions for the flanker task trials that require greater cognitive control. However, faster reaction times were found during moderate-intensity exercise. Neuroelectric measures revealed increased N2 and P3 amplitudes during both exercise conditions relative to rest. Together, these findings suggest divergent effects of exercise on behavioral performance measures accompanied by an upregulation of cognitive control during aerobic exercise. These impairments are discussed in terms of dual-task paradigms and the transient hypofrontality theory.

    In order to investigate the dynamic wetting behavior of thermally modified wood, Cathay poplar (Populus cathayana Rehd.) and Scots pine (Pinus sylvestris L.) samples were thermally modified in an oven at 160, 180, 200, 220 or 240 °C for 4 h in this study. The dynamic contact angles and droplet volumes of water droplets on modified and unmodified wood surfaces were measured by sessile drop method, and their changing rates (expression index: K value and wetting slope) calculated by wetting models were illustrated for mapping the dynamic wetting process. The surface chemical components were also measured by X-ray photoelectron spectroscopy analysis (XPS), thus the relationship between dynamic wetting behavior and chemical components of thermally modified wood were determined. The results indicated that thermal modification was capable of decreasing the dynamic wettability of wood, expressed in lowing spread and penetration speed of water droplets on wood surfaces. This change was more obvious with the increased heating temperature. The K values varied linearly with the chemical components parameter (mass loss, O/C ratio, and C1/C2 ratio), indicating a strong correlation between dynamic wetting behavior and chemical components of thermally modified wood.

    Calcium pyrophosphate dihydrate (CPP) crystal deposition in the articular cartilage can often be seen radiographically as chondrocalcinosis (CC). CPP crystals preferentially deposit in fibrocartilages such as the knee menisci and symphysis pubis (SP). We sought to determine the prevalence of CC in the SP on computed tomography (CT) of the abdomen and pelvis. This retrospective study involved readings on 1070 consecutive CTs of the abdomen and pelvis performed over 3 months in patients over 65 years of age. Medical records of 226 patients found to have CC were reviewed to determine age, gender, documentation of CPPD on problem lists or in medical histories, and whether radiology readings of the CTs mentioned CC. SP CC was identified in 21.1 % (226/1070) of consecutive CT scans with the mean age of CT+ patients being 78.6. Of the 226 patients with SP CC, the observation of CC was documented in only 5.3 % (12/226) of the radiology reports. Of the 12 instances in which the radiology reports mentioned CC, this observation was never (0/12) transmitted to the medical history or problem list. The prevalence of SP CC in patients older than 65 was 21.1 %. Since the majority of CTs of the abdomen and pelvis are not ordered for evaluation of musculoskeletal conditions, this is likely a true prevalence without selection bias. When CC of the SP was present on images, radiologists routinely overlooked or chose not to report CC. Even in the rare instances when it was reported, that information was not added to the medical history or problem list. There are several clinical situations (e.g., acute monoarthritis or atypical osteoarthritis) in which recognizing that a patient has CPP deposition would be useful. Taking the time to review images may yield clinically important findings that are not mentioned anywhere on the patient chart.

    Full Text Available Debate on single-sex vs. coeducational schooling has increased over the last years. The purpose of the following study is to produce empirical evidence on this debate by comparing the frequency of disruptive behaviors in students thatattend single-sex and coeducational schools, in order to find statistical correlation.The frequency of disruptive behaviors in students coming from 5 single-sex schools was compared to that coming from 5 coeducational ones. Data came from 844 students aged 14, attending public schools in Callao, Peru. Students from single-sex schools showed less frequent disruptive behavior in each of the three measured categories—disruptive behaviors, behaviors that show lack of responsibility and anti-social behavior. A weak correlation was found between each of the three categories and the main variable. The study controlled for extraneous variables.

    Virtual reality (VR) offers a unique method for eliciting state-variable fluctuations in body satisfaction and associated behaviors by allowing near-perfect control over environmental factors. Greater variability in momentary body satisfaction is associated with more problematic eating behavior and cognitive styles predictive of eating disorders. The field currently lacks a model for understanding environmental variables and everyday events that tend to influence fluctuations in state body satisfaction. This study proposes a model of state-level body satisfaction and presents a method for measuring changes as they occur. We aim to investigate body comparison, selective attention and body checking behaviors in relation to self-report levels of state body satisfaction. We additionally assess interpersonal correlates of state body satisfaction using VR to measure personal distance between subjects and avatars of varying body sizes. 80 female college students with varying levels of weight and shape concerns will be exposed to five virtual environments designed to elicit varying levels of body dissatisfaction: (a) an empty room; (b) an empty beach; (c) a beach populated with avatars; (d) an empty party scene; (e) a party scene populated with avatars. Self-report body satisfaction was measured immediately following each exposure. A tracking system automatically tracked subjects' head orientation and body translation to measure visual gaze and personal space behavior relative to each virtual human within the environment. Data collection is currently underway and expected to be completed by May 2013. Preliminary data and development of the VR model for state-variable assessment will be presented.

    Bullying is a prevalent problem in schools that is associated with a number of negative outcomes for both the child who bullies and his or her victims. In a community sample of 284 ethnically diverse school-children (54.2 % girls) between the ages of 9 and 14 years (M = 11.28, SD = 1.82), the current study examined whether the level of victimization moderated the association between bullying and several behavioral, social, and emotional characteristics. These characteristics were specifically chosen to integrate research on distinct developmental pathways to conduct problems with research on the characteristics shown by children who bully others. Results indicated that both bullying and victimization were independently associated with conduct problems. However, there was an interaction between bullying and victimization in the prediction of callous-unemotional (CU) traits, such that the association between bullying and CU traits was stronger for those lower on victimization. Further, bullying was positively associated with positive attitudes towards bullying and anger expression and neither of these associations were moderated by the level of victimization. In contrast, bullying was not associated with the child's perceived problems regulating anger, suggesting that children with higher levels of bullying admit to expressing anger but consider this emotional expression as being under their control.

    Since the beginning of the AIDS pandemic, opportunistic infections have been recognized as common complications of HIV infection. Enteric protozoan parasitic infections are one of the leading causes of morbidity and mortality in HIV infected patients. The present study is, therefore, aimed to determine the prevalence of these parasites and study their association with immune status in HIV patients with emphasis on the correlation between various diagnostic techniques to give an accurate diagnosis to avoid empirical treatment. This prospective study, carried out between November 2009 and May 2010 included all HIV seropositive patients presenting with diarrhea to the ART center. A total of 64 stool samples were analyzed by wet mount examination, three different staining techniques, and antigen detection by ELISA for various enteric protozoan infections. Total prevalence of enteric protozoan parasites was 30%. Among the total cases, Cryptosporidium was seen in 12% cases followed by Giardia, E. histolytica and Isospora belli. The maximum diagnostic yield for coccidian parasites was with safranin-methylene blue staining technique. Parasitic burden contributes towards early morbidity in HIV infection. This study provides important information about prevalence of intestinal protozoan parasites in HIV infection. A combination of procedures should be carried out for the screening of stool specimens of HIV patients for better diagnosis and management.

    Very few studies examined the prevalence and sport-related predictors of disturbed eating attitudes and behaviors (DEABs) among adolescents involved in sport practice, and their results are mixed and inconclusive. These inconsistencies are most likely due to their methodological heterogeneity and to the fact that none of these studies took into consideration the potentially relevant characteristics of the sport practice context. This study attempts to answer this limitation among French adolescents not involved or involved in various sports contexts defined based on their organization, leanness-centration, and competitive level. Participants were 335 adolescents involved in sport practice, and 435 adolescents not involved in any form of regular sport practice. The DEABs were measured using the Eating Attitudes Test-26. Global results do not showed any significant association between the status of the participants and DEAB. However, these results drastically changed when we considered the potential moderating role of sex and age on these relations. Indeed, sports involvement in general, and involvement in leanness and competitive sports were found to exert sex- and age-differentiated effects on the risks of presenting clinically significant levels of DEAB. This study suggests the importance of monitoring, preventive, and early intervention mechanisms within the context of practice, particularly for adolescent girls.

    The paper presents the results of the research and a comparative analysis of findings on key indicators for the study population. The study instrument was a standardized behavior study questionnaire provided in the Family Health International published manual (Family Health International, 2000). The target group was female sex workers working in Tirana. The prevalence of biological infections was low. HIV was detected in one case. Syphilis and Hepatitis B rates resulted to be respectively 6.5% and 7.6%. The median age of the study participants is 28 years. Almost 38% of the participants were illiterate, and more than half belong to the Roma community. Almost 50% of the respondents had received money in exchange of sex for the first time 18 years earlier. Almost 65% of respondents reported two or more different sex partners in the last seven days, while almost 30% referred five or more. Condom use at last sex with a paying client was reported by almost 68%. Consistent condom use with paying clients in the last month was reported by almost 35% of the respondents.

    Full Text Available Background Developmental cordination disorder (DCD is a serious deficit in development of motor coordination, which affects educational achievements and daily life activities to a considerable extent. Objectives The present study aimed to investigate correlations between components of executive function and spelling and math performance of 7 - 11-year-old children with DCD. Materials and Methods A descriptive-analytic study was conducted on 53 primary school children with DCD. Persian version of motor observation questionnaire for teachers (PMOQ-T was used to detect DCD. Executive functions and educational achievements of these children were evaluated using behavior rating inventory of executive function (BRIEF and a researcher-made test, respectively. Results were analyzed through SPSS software (v. 21 and Pearson correlation coefficient. Results The findings showed that components of inhibition (r = -0.27, P < 0.05, working memory (r = -0.44, P < 0.01 and organization of material (r = -0.28, P < 0.05 were significantly correlated with the spelling test. And components of inhibition (r = -0.27, P < 0.05, shift (r = -0.38, P < 0. 01, working memory (r = -0.28, P < 0.05, and planning (r = -.29, P<0.05 were correlated with math test. Conclusions The results may help clinicians for early intervention and focus on related components of executive function to improve the educational performance of DCD children. Knowing that executive function skills are associated with these two achievement domains suggests potentiality of targeted math and spelling interventions for DCD children.

This study was designed to clarify whether a relationship exists between the serum levels of homocysteine and the behavioral and psychological symptoms of dementia.Methods: Patients with Alzheimer’s disease (n=77 and control subjects (n=37 were included in this study. History taking, physical examination, and cognitive assessment were carried out as part of the investigation for the diagnosis of Alzheimer’s disease based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The Mini-Mental State Examination, Global Deterioration Scale, Clinical Dementia Rating, and the Korean version of the Neuro­psychiatric Inventory were applied to all patients. The patients’ serum homocysteine, folate, and vitamin B12 levels were measured.Results: Patients with Alzheimer’s disease had statistically significantly lower Mini-Mental State Examination scores and higher serum homocysteine levels compared to the control subjects. Mean serum folate and vitamin B12 concentration were significantly lower in patients with Alzheimer’s disease compared to control subjects. A statistically significant positive correlation was found between the serum homocysteine levels and the Neuropsychiatric Inventory subdomains, including delusion, agitation/aggression, depression/dysphoria, elation/euphoria, apathy/indifference, and disinhibition. No statistically significant correlation was found between the serum homocysteine concentration and the Mini-Mental State Examination, Global Deterioration Scale, or Clinical Dementia Rating.Conclusion: Associations between the serum homocysteine levels and behavioral and psychological symptoms of dementia were observed, raising the possibility of an etiological role.

    Background and Rationale: Residents work in emotionally demanding environments with multiple stressors. The risk for burnout is high in them and it has significant negative consequences for their career. Burnout is also associated with consequences in terms of physical and mental health including insomnia, cardiovascular disease, depression and suicidal ideation. Thus, the study aimed to study the prevalence of burn out and its correlates among interns and residents at Government Medical College, Thiruvananthapuram, Kerala, India. Settings and Design: Cross Sectional Study at Government Medical College, Thiruvananthapuram, Kerala, India. Methods: It was a cross Sectional study of 558 interns and residents of Government Medical College, Thiruvananthapuram, Kerala, India. Data was collected which included the Copenhagen Burnout Inventory [CBI] which assesses burnout in the dimensions of Personal burnout, Work burnout and Patient related burnout, with a cut off score of 50 for each dimension. Age, sex, year of study, department the resident belonged to, or an intern, junior resident or a super speciality senior resident (resident doing super speciality course after their post graduate masters degree) were the correlates assessed. Statistical analysis: Univariate analysis. Results: More than one third of the participants were found to have burnout in one or another dimension of the CBI. Burnout was found to be the highest among the interns in the domains of personal burnout (64.05 %) and patient related burnout (68.62 %) and in junior residents for work related burnout (40%). Super specialty senior residents had the least prevalence of burnout in all three dimensions. Among the residents, Non Medical/Non Surgical residents had the least prevalence of burnout in all three dimensions, whereas surgical speciality residents had the highest of personal burnout (57.92 %) and Medical speciality residents had the highest patient related burnout (27.13%).

    The intracellular bacteria Coxiella (C) burnetii and Chlamydia (Chl) abortus induce abortion in sheep and also affect humans. While Chl. abortus only infrequently infects humans, C burnetii is the aetiological agent of numerous Q fever outbreaks during the last decades. There is only limited knowledge about the prevalence of both pathogens in sheep, although sheep are involved in almost all Q fever outbreaks in Germany. The aim of our study was to investigate the prevalence of both pathogens in flocks located in Lower Saxony, Germany, in correlation to the management form and abortion rate. Serum samples of 1714 sheep from 95 flocks located in Lower Saxony were investigated by ELISA. 2.7% of these samples were positive, 1.3% showed inconclusive results in the C. burnetii-ELISA. Elevated intra-flock seroprevalences were only detected in three migrating flocks. Chlamydia-specific antibodies could be detected in 15.1% serum samples of mainly shepherded and migrating flocks. In one of these flocks with a high intra-flock seroprevalence for C burnetii (27%) and Chlamydia (44.9%), C burnetii was detected in 21.6% of the placenta samples of normal births and in 12.5% of the colostrum samples by PCR. Aborted fetuses and the corresponding placentas were negative in C burnetii-PCR, but in most of them and also in many other placenta samples Chl. abortus could be detected by PCR and DNA microarray. This survey shows a low overall prevalence of C. burnetii in sheep in Lower Saxony in the year 2004. However, three migrating flocks with a high intra-flock prevalence are localized in the southern parts of Lower Saxony. Spreading of C burnetii could occur, because of the large radius of grazing of all three flocks.

    People often exert willpower to choose a more valuable delayed reward over a less valuable immediate reward, but using willpower is taxing and frequently fails. In this research, we demonstrate the ability to enhance self-control (i.e., forgoing smaller immediate rewards in favor of larger delayed rewards) without exerting additional willpower. Using behavioral and neuroimaging data, we show that a reframing of rewards (i) reduced the subjective value of smaller immediate rewards relative to larger delayed rewards, (ii) increased the likelihood of choosing the larger delayed rewards when choosing between two real monetary rewards, (iii) reduced the brain reward responses to immediate rewards in the dorsal and ventral striatum, and (iv) reduced brain activity in the dorsolateral prefrontal cortex (a correlate of willpower) when participants chose the same larger later rewards across the two choice frames. We conclude that reframing can promote self-control while avoiding the need for additional willpower expenditure.

    Latent toxoplasmosis is probably the most common protistan parasitic disease with many indirect negative impacts on human health. One of the important impacts is impaired psychomotor function leading to reduced driving efficiency in Toxoplasma-seropositive subjects. Numerous case-control studies have established a positive relation between the seroprevalence of Toxoplasma gondii (Nicolle et Manceaux, 1908) and probability of traffic accidents in study populations. The prevalence of toxoplasmosis varies between populations according to local geographical conditions, hygienic practices and kitchen habits. Similarly, we see a striking variation in the incidence of traffic accidents across countries. Hence, we compiled the largest ever data set on the seroprevalence of toxoplasmosis and tried to understand its role in traffic accident-related deaths and disabilities across 87 countries. Simple non-parametric analysis showed a positive and strong relation of T. gondii seroprevalence and traffic accident related disabilities. Further, we conducted multivariate analysis to control for confounding factors. After controlling for wealth, geographical latitude, health of population, length of roads and number of vehicles, the correlation disappeared. When the frequency of RhD negativity and its interaction with toxoplasmosis were included into the model, the effects of toxoplasmosis seemingly returned. However, the analysed data suffered from the problem of multicollinearity. When a proper method of analysis, ridge regression, was applied, the effects of toxoplasmosis prevalence and RhD negativity frequency disappeared again. The existence of a strong correlation between the prevalence of toxoplasmosis and health of population in particular countries, which was the probable cause of multicollinearity and possible reason for the negative result of the present study, suggests that 'asymptomatic' latent toxoplasmosis could have a large impact on public health.

    Full Text Available Increasing burden of STDs is one of China's major public health concerns. However, only a limited number of studies have ever investigated the prevalence of these STDs, particular for genital warts and its correlates among heterosexual males attending STD clinics in China. In order to fill this gap, we conducted a cross-sectional study among MSCs in Jiangmen, China, between the years of 2009 and 2010.The eligible participants were recruited from several STD-clinics in public hospitals. We collected demographic information and behaviors of the participants. After HIV and syphilis testing, we further checked whether the participants had genital warts and genital herpes. In addition, urine samples were collected from part of the participants for CT and NG testing.Of the 533 eligible participants, over three-fifths were aged 35 or below, nearly three quarters had no college degree, over three-fifths were residence of Jiangmen. The prevalence of HIV, syphilis, genital warts, genital herpes, CT and NG were 0.19%, 7.50%, 7.32%, 5.25%, 9.73% and 6.19%, respectively. Living with family members (versus living alone, no STD-related service in past year, experiencing STDs related symptoms in past year, and sex with FSWs in last three months were positively associated with genital warts, with adjusted ORs of 5.54 (95% CI 1.94-15.81, 2.26 (95% CI 1.08-4.74, 1.99 (95% CI 1.00-3.99 and 2.01 (95% CI 1.00-4.04, respectively.Our study indicates that the prevalence of STDs among MSCs in Jiangmen was high, which may further spread HIV among MSCs.

  11. On the correlation between the electroanalytical behavior and crystallographic features of Li-intercalation electrodes

    Levi, M. D.; Levi, E.; Aurbach, D.; Schmidt, M.; Oesten, R.; Heider, U.

    The electroanalytical behavior of Li xNiO 2 and Li xCo 0.2Ni 0.8O 2 was studied by simultaneous application of slow-scan rate cyclic voltammetry (SSCV), potentiostatic and galvanostatic intermittent titration (PITT and GITT), and electrochemical impedance spectroscopy (EIS). Application of a finite-space diffusion model for treating the results obtained by these techniques allowed us to calculate the diffusion coefficient of Li ions ( D) and the differential (incremental) capacity ( Cint) as functions of the electrode's potential. Our final purpose was to compare D versus E and Cint versus E plots for both the electrodes, in order to correlate the observed difference in their electroanalytical behavior with the clear distinction in the related Li-insertion mechanisms deduced from XRD studies. While Li insertion into Li xCo 0.2Ni 0.8O 2 exhibits a single-phase reaction upon charge in the 3.0-4.08 V (versus Li/Li +) range, Li intercalation into Li xNiO 2 undergoes two-phase transitions in the same potential range. The shape of both plots, D versus E and Cint versus E for these electrodes, is discussed in the framework of a finite-space diffusion model and Li-insertion processes that can be described by Frumkin-type intercalation isotherms with short-range attraction interactions among intercalation sites.

    Studies of animal personality improve our understanding of individual variation in measures of life history and fitness, such as health and reproductive success. Using a 54 trait personality questionnaire developed for studying great apes and other nonhuman primates, we obtained ratings on 116 wild mountain gorillas (Gorilla beringei beringei) monitored by the Dian Fossey Gorilla Fund's Karisoke Research Center in Rwanda. There were 8 raters who each had more than 1.5 years of working experience with the subjects. Principal component analyses identified 4 personality dimensions with high interrater reliabilities-Dominance, Openness, Sociability, and Proto-Agreeableness-that reflected personality features unique to gorillas and personality features shared with other hominoids. We next examined the associations of these dimensions with independently collected behavioral measures derived from long-term records. Predicted correlations were found between the personality dimensions and corresponding behaviors. For example, Dominance, Openness, Sociability, and Proto-Agreeableness were related to gorilla dominance strength, time spent playing, rates of approaches, and rates of interventions in intragroup conflicts, respectively. These findings enrich the comparative-evolutionary study of personality and provide insights into how species differences in personality are related to ecology, social systems, and life history.

    Neuropeptides play vital roles in orchestrating neural communication and physiological modulation in organisms, acting as neurotransmitters, neuromodulators, and neurohormones. The highly evolved social structure of honeybees is a good system for understanding how neuropeptides regulate social behaviors; however, much knowledge on neuropeptidomic variation in the age-related division of labor remains unknown. An in-depth comparison of the brain neuropeptidomic dynamics over four time points of age-related polyethism was performed on two strains of honeybees, the Italian bee (Apis mellifera ligustica, ITb) and the high royal jelly producing bee (RJb, selected for increasing royal jelly production for almost four decades from the ITb in China). Among the 158 identified nonredundant neuropeptides, 77 were previously unreported, significantly expanding the coverage of the honeybee neuropeptidome. The fact that 14 identical neuropeptide precursors changed their expression levels during the division of labor in both the ITb and RJb indicates they are highly related to task transition of honeybee workers. These observations further suggest the two lines of bees employ a similar neuropeptidome modification to tune their respective physiology of age polyethism via regulating excretory system, circadian clock system, and so forth. Noticeably, the enhanced level of neuropeptides implicated in regulating water homeostasis, brood pheromone recognition, foraging capacity, and pollen collection in RJb signify the fact that neuropeptides are also involved in the regulation of RJ secretion. These findings gain novel understanding of honeybee neuropeptidome correlated with social behavior regulation, which is potentially important in neurobiology for honeybees and other insects.

    Experience can affect human gray matter volume. The behavioral correlates of individual differences in such brain changes are not well understood. In a group of Swedish individuals studying Italian as a foreign language, we investigated associations among time spent studying, acquired vocabulary, baseline performance on memory tasks, and gray matter changes. As a way of studying episodic memory training, the language learning focused on acquiring foreign vocabulary and lasted for 10weeks. T1-weighted structural magnetic resonance imaging and cognitive testing were performed before and after the studies. Learning behavior was monitored via participants' use of a smartphone application dedicated to the study of vocabulary. A whole-brain analysis showed larger changes in gray matter structure of the right hippocampus in the experimental group (N=33) compared to an active control group (N=23). A first path analyses revealed that time spent studying rather than acquired knowledge significantly predicted change in gray matter structure. However, this association was not significant when adding performance on baseline memory measures into the model, instead only the participants' performance on a short-term memory task with highly similar distractors predicted the change. This measure may tap similar individual difference factors as those involved in gray matter plasticity of the hippocampus.

    This study was designed to assess physiological and behavioral correlates of academic stress during a college course in organic chemistry in the USA. Participants (45 females, 46 males, mean age 19.88 years) were screened for their basal hypothalamic-pituitary-adrenocortical activity using saliva samples collected at the beginning of the course and after each major test. Displacement activities (DAs) were observed during each test by videotaping students' behavior when they were taking the tests. These variables were then used as predictors of the students' achievement as measured by their grade point average (GPA) scores, American College Testing (ACT) scores, and their final grade in the class. Ninety-one students, enrolled in Organic Chemistry I at Marshall University during the summer of 2009, were recruited for this study. It was found that individual differences in the physiological stress responses are a factor in predicting the students' ability to pass a challenging class. A logistic model built on GPA, DAs during stress, and salivary hormone (cortisol and dehydroepiandrosterone) concentrations was able to correctly classify almost 90% of the students passing the class. The same model was not nearly as successful in determining the possible factors behind failing the class, because the classification success was just 52%, a figure close to chance. We conclude that a clear set of characteristics related to the students' ability and resilience to psychological stress are necessary to succeed in a challenging class. The reason behind dropping or failing a class could be less defined. These data indicated that investigating the physiological and behavioral propensities associated with psychological stress can help us better understand an individual's coping responses to a long-term challenging situation.

    Background There has been increased attention for the need to reduce stigma related to sexual behaviors among gay men and other men who have sex with men (MSM) as part of comprehensive human immunodeficiency virus (HIV) prevention and treatment programming. However, most studies focused on measuring and mitigating stigma have been in high-income settings, challenging the ability to characterize the transferability of these findings because of lack of consistent metrics across settings. Objective The objective of these analyses is to describe the prevalence of sexual behavior stigma in the United States, and to compare the prevalence of sexual behavior stigma between MSM in Southern and Western Africa and in the United States using consistent metrics. Methods The same 13 sexual behavior stigma items were administered in face-to-face interviews to 4285 MSM recruited in multiple studies from 2013 to 2016 from 7 Sub-Saharan African countries and to 2590 MSM from the 2015 American Men’s Internet Survey (AMIS), an anonymous Web-based behavioral survey. We limited the study sample to men who reported anal sex with a man at least once in the past 12 months and men who were aged 18 years and older. Unadjusted and adjusted prevalence ratios were used to compare the prevalence of stigma between groups. Results Within the United States, prevalence of sexual behavior stigma did not vary substantially by race/ethnicity or geographic region except in a few instances. Feeling afraid to seek health care, avoiding health care, feeling like police refused to protect, being blackmailed, and being raped were more commonly reported in rural versus urban settings in the United States (P<.05 for all). In the United States, West Africa, and Southern Africa, MSM reported verbal harassment as the most common form of stigma. Disclosure of same-sex practices to family members increased prevalence of reported stigma from family members within all geographic settings (P<.001 for all). After

    Full Text Available Executive functions (EF are cognitive capacities that allow for planned, controlled behavior and strongly correlate with academic abilities. Several extracurricular activities have been shown to improve EF, however, the relationship between musical training and EF remains unclear due to methodological limitations in previous studies. To explore this further, two experiments were performed; one with 30 adults with and without musical training and one with 27 musically trained and untrained children (matched for general cognitive abilities and socioeconomic variables with a standardized EF battery. Furthermore, the neural correlates of EF skills in musically trained and untrained children were investigated using fMRI. Adult musicians compared to non-musicians showed enhanced performance on measures of cognitive flexibility, working memory, and verbal fluency. Musically trained children showed enhanced performance on measures of verbal fluency and processing speed, and significantly greater activation in pre-SMA/SMA and right VLPFC during rule representation and task-switching compared to musically untrained children. Overall, musicians show enhanced performance on several constructs of EF, and musically trained children further show heightened brain activation in traditional EF regions during task-switching. These results support the working hypothesis that musical training may promote the development and maintenance of certain EF skills, which could mediate the previously reported links between musical training and enhanced cognitive skills and academic achievement.

    It is well known that testosterone (T) influences the expression of the behavior and many sexual traits during reproduction in vertebrates. However, patterns of circulating concentrations of T vary tremendously across free-living populations. Here the profiles of plasma T levels in the Magnificent Frigatebird, Fregata magnificens, are presented during the courtship, incubation and chick rearing stages of breeding. In addition, the predicted interrelationship of T and the expression of a sexually selected trait, the red gular pouch of males is investigated. Plasma levels of corticosterone (Cort) are reported in relation to the demands of breeding conditions in colonies. Blood samples were obtained from 26 males and 32 females in the 1993-1994 breeding season and 41 courting males in 1997. Pouch color and size were also estimated in these males. As expected, T levels changed across the breeding stages: birds showed high levels of T during courtship and much lower circulating levels during incubation and chick rearing. Consistent with the expected effect of T, individual pouch color and size correlated with circulating levels of this hormone. In this highly dimorphic species no correlation was found between T and body condition or tail asymmetry. Cort, in contrast, did not change across the three reproductive stages.

    Full Text Available Intimate partner violence (IPV is associated with increased risk of HIV among women globally. There is limited evidence and understanding about IPV and potential HIV risk pathways among sex workers (SWs. This study aims to longitudinally evaluate prevalence and correlates of IPV among street and off-street SWs over two-years follow-up.Longitudinal data were drawn from an open prospective cohort, AESHA (An Evaluation of Sex Workers Health Access in Metro Vancouver, Canada (2010-2012. Prevalence of physical and sexual IPV was measured using the WHO standardized IPV scale (version 9.9. Bivariate and multivariable logistic regression using Generalized Estimating Equations (GEE were used to examine interpersonal and structural correlates of IPV over two years.At baseline, 387 SWs had a male, intimate sexual partner and were eligible for this analysis. One-fifth (n = 83, 21.5% experienced recent physical/sexual IPV at baseline and 26.2% over two-years follow-up. In multivariable GEE analysis, factors independently correlated with physical/sexual IPV in the last six months include: childhood (<18 years sexual/physical abuse (adjusted odds ratio [AOR] = 2.05, 95% confidence interval [CI]: 1.14-3.69, inconsistent condom use for vaginal and/or anal sex with intimate partner (AOR = 1.84, 95% CI: 1.07-3.16, correlates of IPV uncovered here highlight potential HIV risk pathways through SWs' intimate, non-commercial partner relationships. The high prevalence of IPV among SWs is a critical public health concern and underscores the need for integrated violence and HIV prevention and intervention strategies

    Full Text Available ABSTRACT: The aim of this study was to correlate Streblidae parasitism rates with temperature and humidity as well as sex, age and reproductive condition of Artibeus bats. Streblidae specimens were collected during two years in the Tinguá Biological Reserve and in two areas inside buffer zone, located in Nova Iguaçu, Rio de Janeiro State and preserved as wet specimens. The abundance of Streblidae species parasitizing Artibeus was analyzed, and no differences were found between them. However, the number of females parasitizing Artibeus fimbriatus was higher. Moreover, regarding sex, Artibeus females were more parasitized, particularly A. fimbriatus and A. lituratus. There was no correlation between mean intensity of infestation and body mass index of Artibeus species, even when correlated to abiotic data. This study contributes to better understand the parasitism on Artibeus by Streblidae, and based on results, it is clear that Streblidae show no preferences in terms of reproductive condition, body size, age, sex, temperature and humidity in parasitizing Artibeus species.

    Full Text Available This work aimed to evaluate the correlations between production and milk composition and feeding behavior of lactating cows. The cows had an average of 100 days of lactation and a production were arranged in two 4 x 4 Latin squares conpound of the four periods, four diets and four animals. The diets were formulated to be isonitrogenous with roughage: concentrate ratio of approximately 55:45. As forage, were evaluate four silages sugar cane: without additive (control, with 1% urea, with 0.5% urea + 0.5% CaO and with 1% CaO. The experimental period lasted 60 days divided into four periods of 15 days. Feeding behavior was assessed on the 13 day of each experimental period, for 24 hours, every five minutes. From the data 24 behavioral variables were determined, which were correlated with the data of production and milk composition. The behavioral variable eating and ruminating, DM intake in grams/day, rumination efficiencies in grams of DM and neutral detergent fiber were positively correlated (P<0.05 with milk production in kg/day and the production corrected for 4% fat. However, there was a negative correlation between feeding time and the milk fat percentage. Despite the low values of the correlations can be inferred from the results, the data can be used to develop models to predictyield and composition of milk from the feeding behavior variables.

    Full Text Available IntroductionWe investigated ethnic and geographic variations in major chronic diseases and risk factors in northern Canada, an area that is undergoing rapid changes in its social, cultural, and physical environments.MethodsSelf-report data were obtained from the population-based Canadian Community Health Survey in 2000-2001 and 2005-2006 for Aboriginal and non-Aboriginal respondents from the 3 regions of northern Canada: Yukon, Northwest Territories, and Nunavut. Crude prevalence estimates, adjusted odds ratios (AORs, and confidence intervals were calculated for multiple chronic diseases and risk factors.ResultsThe percentage of Aboriginal respondents who reported having any chronic health condition increased between the 2 cycles of data collection, but did not change for non-Aboriginal respondents. AORs for heart disease, arthritis, and asthma varied by ethnicity or region. AORs for overweight, obesity, daily smoking, regular and binge drinking, and infrequent physical/leisure activity were also substantially different for Aboriginal and non-Aboriginal respondents or among respondents from the 3 northern regions.ConclusionThe changing profile of health in northern Canada suggests a need for action on health policy about the delivery of community-based primary prevention interventions and further research about the determinants of health and health care use.

    Full Text Available Abstract Background The problem of severe mental distress (SMD in sub-Saharan Africa is difficult to investigate given that a substantial proportion of patients with SMD never access formal health care. This study set out to investigate SMD and it's associated factors in a rural population-based cohort in south-west Uganda. Methods 6,663 respondents aged 13 years and above in a general population cohort in southwestern Uganda were screened for probable SMD and possible associated factors. Results 0.9% screened positive for probable SMD. The factors significantly associated with SMD included older age, male sex, low socio-economic status, being a current smoker, having multiple or no sexual partners in the past year, reported epilepsy and consulting a traditional healer. Conclusion SMD in this study was associated with both socio-demographic and behavioural factors. The association between SMD and high risk sexual behaviour calls for the integration of HIV prevention in mental health care programmes in high HIV prevalence settings.

    Camels are seasonal breeders, and their sexual behavior is influenced by environmental conditions, but the relationship between climatic factors and sexual behavior has been poorly described in the available literature. Nowadays, the male camel living habit is shifting towards captivity; thus, this study was carried out to evaluate the sexual behavior of housed male dromedary camel through female's parades and to correlate it with climatic parameters. Four housed sires, reared for semen collection, and one dam were used and the trial lasted 8 weeks, considering the first week as control. Six days per week and during evenings, the female was brought near each males' boxes, while two observers filled a behavioral sampling ethogram and scored the male sexual behavior. After this parade, blood samples were taken from the female to evaluate the estradiol concentration. In addition, the following meteorological parameters were recorded, everyday, at 9:00 a.m. and 19:00 p.m.: pressure, wind, temperature, humidity, and H-index. The correlation between sexual behavioral score and female estradiol concentration and climate parameters was analyzed. All the behavioral parameters showed a significant upward trend; female estradiol concentration varied during the period and picked at week 5. Male sexual behavior was negatively correlated with morning H-index, wind, and temperature, and positively correlated with pressure and evening humidity, whereas it was not correlated with estrogen. In conclusion, female parade was a successful method to evaluate and stimulate the occurrence of housed male dromedary camel sexual activity that resulted to be negatively affected by hot temperature, warm wind, and lack of rain.

    Full Text Available Abstract Background College students are vulnerable to tobacco addiction. Tobacco industries often target college students for marketing. Studies about prevalence of tobacco use and its correlates among college students in Nepal are lacking. Methods A cross-sectional survey was carried out in two cities of western Nepal during January-March, 2007. A pre-tested, anonymous, self-administered questionnaire (in Nepali adapted from Global Youth Tobacco Survey (GYTS and a World Bank study was administered to a representative sample of 1600 students selected from 13 junior colleges by two-stage stratified random sampling. Results Overall prevalence of 'ever users' of tobacco products was 13.9%. Prevalence among boys and girls was 20.5% and 2.9% respectively. Prevalence of 'current users' was 10.2% (cigarette smoking: 9.4%, smokeless products: 6.5%, and both forms: 5.7%. Median age at initiation of cigarette smoking and chewable tobacco was 16 and 15 years respectively. Among the current cigarette smokers, 58.7% (88/150 were smoking at least one cigarette per day. Most (67.8% 'Current users' purchased tobacco products by themselves from stores or got them from friends. Most of them (66.7% smoked in tea stalls or restaurants followed by other public places (13.2%. The average daily expenditure was 20 Nepalese rupees (~0.3 USD and most (59% students reported of having adequate money to buy tobacco products. Majority (82% of the students were exposed to tobacco advertisements through magazines/newspapers, and advertising hoardings during a period of 30 days prior to survey. The correlates of tobacco use were: age, gender, household asset score and knowledge about health risks, family members, teachers and friends using tobacco products, and purchasing tobacco products for family members. Conclusion School/college-based interventions like counseling to promote cessation among current users and tobacco education to prevent initiation are necessary

A cross sectional study was performed from October 2009 to October 2011 among 143 MSM by face-to-face interviews to complete an interviewer-administered questionnaire. Subjects were tested for ,HIV, HBV, HCV, HDV, HTLV-1/2 and toxoplasma infection using serology and for TTV using molecular detection. The seropositive rates for anti-HIV, HBsAg, anti-HCV, anti-HDV, anti-HTLV-1/2, IgM anti-T. gondii, IgG anti-T, gondii and TTV DNA were 9.1%, 9.8%, 28.0%, 0.7%, 0.7%, 1.4%, 30.8%, and 26.6%, respectively. Risk factors associated with HIV infection were a history of injecting drug use (IDU) [adjusted OR (aOR) 6.0; 95% CI: 1.10-33.01] and a receptive role in sexual activity (aOR 8.1; 95% CI: 1.30-50.04) [corrected]. Having a tattoo (aOR 3.2; 95% CI: 1.28-7.98) and practicing both anal and vaginal sex without a condom (aOR 2.3; 95% CI: 1.06-4.92) were associated with toxoplasma infection. A history of IDU (aOR 32; 95% CI: 5.93-177.93) was associated with TTV infection. The subjects examined in this study were found to be infected with HIV, HBV, HCV, HDV, HTLV-1/2, TTV, and T. gondii. These infections were associated with high-risk behavior.

    Full Text Available Abstract Background Early childhood caries (ECC is a serious problem that has remained unexplored in sub-Saharan Africa. This study aimed to identify possible socio-behavioral correlates of ECC focusing 6–36 months old children and their caretakers. Methods Cross sectional studies were conducted in a high fluoride rural area, Manyara, Tanzania and a low fluoride urban area, Kampala, Uganda. Totals of 1221 and 816 child - caretaker pairs attending health care facilities for growth monitoring were recruited in Manyara and Kampala, respectively. All caretakers completed face to face interviews at the health care facility. Children underwent oral clinical examination whereby ECC and Enamel hypoplasia were recorded using the dmft (WHO 1997 and the DDE index (FDI 1992. Results The prevalence of ECC was 3.7% in Manyara and 17.6% in Kampala. According to multiple logistic regression analyses, received oral health information from health worker was the strongest determinant of ECC in Manyara, adjusted OR 0.3, 95% CI 0.09 – 0.93. In Kampala, visible plaque, high sugar intake and presence of enamel hypoplasia associated with ECC, adjusted ORs 2.8 (95% CI 1.61- 4.95, 3.0 (95% CI 1.39 – 6.34 and 2.3 (95% CI 1.36 - 3.95. Conclusion Oral health education aimed at caretakers of 6–36 months, including health care workers’ information regarding the detrimental consequences for oral health of frequent sugar consumption and poor oral hygiene is important for prevention of ECC in Tanzania and Uganda.

    Full Text Available Suicide is the number one cause of death among incarcerated youth. We examined the demographic and forensic risk factors for self-harm in youth in juvenile detention using a Canadian provincial correctional database.We analyzed data from de-identified youth aged 12 to 18 at the time of their offense who were in custody in a Manitoba youth correctional facility between January 1, 2005 and December 30, 2010 (N = 5,102. Univariate and multivariate logistic regression analyses determined the association between staff-identified self-harm events in custody and demographic and custodial variables. Time to the event was examined based on the admission date and date of event.Demographic variables associated with self-harm included female sex, lower educational achievement, older age, and child welfare involvement. Custodial variables associated with self-harm included higher criminal severity profiles, younger age at first incarceration, longer sentence length, disruptive institutional behavior, and a history of attempting escape. Youth identified at entry as being at risk for suicide were more likely to self-harm. Events tended to occur earlier in the custodial admission.Self-harm events tended to occur within the first 3 months of an admission stay. Youth with more serious offenses and disruptive behaviors were more likely to self-harm. Individuals with problematic custodial profiles were more likely to self-harm. Suicide screening identified youth at risk for self-harm. Strategies to identify and help youth at risk are needed.

    Full Text Available Introduction The objective of the paper is to analyze and to assess prevalence of the major behavioral risk factors among adult population (25-64 years of age in the rural and urban areas in the Federation of Bosnia and Herzegovina (FBIH.Methods Data were taken from cross-sectional population survey on the health status population in the FBIH. To ensure a sample representative for the adult population in the FBIH it was applied the two-stage stratified systematic sample. The survey covered a total of 2735 adult population aged 25-64 years, of which 1087 in the urban areas and 1648 in rural areas.Results. The prevalence of smoking among men in rural areas is significantly higher than among men in urban areas (69% vs. 55%, while the prevalence of smoking among women is higher in urban than in rural areas (45% vs. 31%. There is no statistically significant difference in prevalence of obesity and physical activity according to the age groups among men and women in the urban and rural areas. The frequency of changes in behavior related to acquiring healthy living habits in the rural areas is statistically significant among men and women, while in the urban areas there is no statistical significance among the sexes.Conclusions. The results indicate that there are no significant differences in prevalence of factor risks in urban and rural areas. Prevalence of unhealthy lifestyles is high, and the results should be used to improve standard planning of health promotion-prevention programs.

    Full Text Available Over the years, the prevalence of auditory verbal hallucinations (AVH has been documented across the lifespan in varied contexts, and with a range of potential long-term outcomes. Initially the emphasis focused on whether AVHs conferred risk for psychosis. However, recent research has identified significant differences in the presentation and outcomes of AVH in patients compared to those in non-clinical populations. For this reason, it has been suggested that auditory hallucinations are an entity by themselves and not necessarily indicative of transition along the psychosis continuum. This review will examine the presentation of auditory hallucinations across the life span. The stages described include childhood, adolescence, adult non-clinical populations, hypnaogogic/hypnopompic experiences, high schizotypal traits, schizophrenia, substance induced AVH, AVH in epilepsy and AVH in the elderly. In children, need for care depends upon whether the child associates the voice with negative beliefs, appraisals and other symptoms of psychosis. This theme appears to carry right through to healthy voice hearers in adulthood, in which a negative impact of the voice usually only exists if the individual has negative experiences as a result of their voice(s. This includes features of the voices such as the negative content, frequency and emotional valence as well as anxiety and depression, independently or caused by voices presence. It seems possible that the mechanisms which maintain AVH in non-clinical populations are different from those which are behind AVH presentations in psychotic illness. For example; the existence of maladaptive coping strategies in patient populations is one significant difference between clinical and non-clinical groups which is associated with a need for care. Whether or not these mechanisms start out the same and have differential trajectories is not yet evidenced. Future research needs to focus on the comparison of underlying

    Full Text Available Low back pain is a major public health problem all over the world. It is generally assumed that overweight, height and low back pain are related. However, the scientific evidence to support this relationship is not fully conclusive. The aim of this study is to estimate the prevalence of low back pain and its association with height, fat distribution, reproductive history and socioeconomic influence. A representative sample of 401 men and 403 women aged 20 years and above were selected and studied. It is found that 28.4% and 52.9% respectively were having low back pain. Height and fat distribution were found to have no association with low back pain. Both men and women, whose household were in the lower socio economic status reported more back pain (Adjusted odds ratio (AOR for men 1.61, 95% confidence interval (CI: 1.02, 2.55 and AOR for women 1.57, 95% CI: 1.02, 2.34. Men with lower educational qualification reported more back pain (AOR 1.89, 95% CI: 1.08, 3.31. In women, those who have undergone caesarean section (AOR 1.661, 95% CI: 1.02, 2.72 and sterilization (AOR 1.63, 95% CI: 1.09, 2.44 were found to be a positively associated with low back pain. The only socioeconomic link with back pain among women seemed to be manual occupation (AOR 3.33, 95% CI: 1.49, 7.4. The finding confirms the higher burden of back pain on the socially disadvantaged, but cannot yet be explained by known risk factors.

    Full Text Available Background: By considering important role of nutrition in children and teenagers’ health, their nutritional status are determined as obesity and wasting using weight and height. The aim of this study is to evaluate the prevalence of obesity and wasting and their relationship to food intake in female students of junior schools in Zahedan. Methods: In a descriptive analytical cross-sectional study, 687 female students from junior schools were selected by multiple stage sampling method. After recording the participants’ demographic data, their weight and height were measured for body mass index (BMI calculation according to standard method. National Center for Health Statistics (NCHS and National Health and Nutritional Examination Survey (NHANES II data and a 48-hour recall questionnaire were used. Results: Of the surveyed girls, 16.9%, 31.7% and 13.2% were wasted, under weight and stunted, respectively 8.7% and 1.7% were over weight and obese, respectively. The mean of energy intake was 1502.1±415.7 kcal/d in the students which is less than the recommended dietary allowances (RDA and there were no balances in daily intake of protein, carbohydrate and lipids. In respect to energy and protein intake, 94.1% and 26.6% of students had deficiency, respectively. On the other hand, findings showed iron (72.1%, calcium (99.8%, phosphorus (83.6%, zinc (84.3%, vitamin A (63.8% and B12 (66.5% intake deficiencies. Conclusion: The female students of junior schools of Zahedan do not have a proper nutritional status according to physical state, energy, protein, and micronutrients intakes and they are at the risk of wasting and underweight. Therefore, we suggest implementation of programs for nutritional support and designing of proper patterns of food consumption to improve female junior students’ nutritional status.

    Full Text Available Basal-like breast cancer, an aggressive subtype associated with high grade, poor prognosis, and younger age, is reported frequently in Africa. We analyzed the expression of the basal cytokeratins (CKs 5/6 and 17 in a case series from Central Sudan and investigated correlations among basal CK status, ER, PgR, and Her-2/neu, and individual/clinicopathological data. Of 113 primary breast cancers 26 (23%, 38 (34%, and 46 (41% were, respectively, positive for CK5/6, CK17, and combined basal CKs (CK5/6 and/or CK17. Combined basal CK+ status was associated with higher grade (P<.03 and inversely correlated with ER (P<.002, PgR (P=.004 and combined ER and/or PgR (P<.0002. Two clusters based on all tested markers were generated by hierarchical cluster analysis and k-mean clustering: I: designated ``hormone receptors positive/luminal-like’’ and II: designated ``hormone receptors negative’’, including both basal-like and Her-2/neu+ tumors. The most important factors for dataset variance were ER status, followed by PgR, CK17, and CK5/6 statuses. Overall basal CKs were expressed in a fraction of cases comparable to that reported for East and West African case series. Lack of associations with age and tumor size may represent a special feature of basal-like breast cancer in Sudan.

    Full Text Available Background: This cross-sectional study evaluated the association between unhealthy lifestyle behaviors and the prevalence of chronic kidney disease (CKD in middle-aged and older men. Methods: The subjects included 445 men without a history of cardiovascular disease, stroke, or dialysis treatment, who were not taking medications. Unhealthy lifestyle behaviors were evaluated using a standardized selfadministered questionnaire and were defined as follows: 1 lack of habitual moderate exercise, 2 lack of daily physical activity, 3 slow walking speed, 4 fast eating speed, 5 late-night dinner, 6 bedtime snacking, and 7 skipping breakfast. The participants were divided into four categories, which were classified into quartile distributions based on the number of unhealthy lifestyle behaviors (0–1, 2, 3, and ≥4 unhealthy behaviors. Results: According to a multivariate analysis, the odds ratio (OR for CKD (defined as estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m2 and/or proteinuria was found to be significantly higher in the ≥4 group than in the 0–1 group (OR 4.67; 95% confidence interval [CI], 1.51–14.40. Moreover, subjects’ lack of habitual moderate exercise (OR 3.06; 95% CI, 1.13–8.32 and presence of late-night dinner (OR 2.84; 95% CI, 1.40–5.75 and bedtime snacking behaviors (OR 2.87; 95% CI, 1.27–6.45 were found to be significantly associated with the prevalence of CKD. Conclusions: These results suggest that an accumulation of unhealthy lifestyle behaviors, especially those related to lack of habitual moderate exercise and presence of late-night dinner and bedtime snacking may be associated with the prevalence of CKD.

    This article aims at estimating the prevalence of adults engaging in protective and risk health behaviors among members of private health insurance plans. It was used a random sample of individuals over the age of 18 living in the Brazilian state capitals collected on 28,640 telephone interviews in 2008. The results showed that among males there was a high prevalence of the following risk factors: tobacco, overweight, low fruit and vegetable consumption, high meat with fat consumption and alcohol drinking. Among females we found a high prevalence of high blood pressure, diabetes, dyslipidemia and osteoporosis. Men were generally more physically active and women consumed more fruit and vegetables. As more educated males were lower was the prevalence of tobacco, high blood pressure, but also a higher prevalence of overweight, consumption of meat with fat, dyslipidemia and lower number of yearly check-ups done. For females, tobacco smoking, overweight, obesity, decreasing with schooling, and consumption of fruit and vegetables, physical activity, mammography and PAP test, increased with schooling. The health insurance user population constitutes about 26% of Brazilian people and the current study aims to accumulate evidence for health promotion actions by this public.

    The aim of this study was to determine the association of dental health behavior with health awareness, oral condition, and subjective symptoms in Japan. The present study included 1699 individuals who underwent dental checkups at the public health center of Miura City. All those who underwent dental checkups were asked to fill out a questionnaire. The correlation between having a regular dentist and each of the other items was analyzed. Undergoing regular checkups was significantly related to having a regular dentist. To analyze the correlation of dental health behavior with Subjective symptoms and Health awareness, structured equation modeling was performed following factor analysis. As a result, only the regression weight between dental health behavior and health awareness was found to be statistically significant. The present survey indicates that dental health behavior was significantly related to Health awareness but not to Subjective symptoms.

    The current study aimed to compare the prevalence, stability, and psychosocial correlates of DSM-IV-TR and DSM-5 eating disorders, in a population-based sample of male and female adolescents followed prospectively from 14 to 20 years of age. Participants (N = 1,383; 49% male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, a prospective, population-based cohort study that has followed participants from prebirth to young adulthood. Detailed self-report questionnaires were used to assess eating disorder symptoms when participants were aged 14, 17, and 20 years. Comparisons between DSM-IV-TR and DSM-5 were conducted using McNemar chi-square tests and Fisher's exact tests. Changes in eating disorder prevalence over time were considered using generalized estimating equations. Eating disorder prevalence rates were significantly greater when using DSM-5 than DSM-IV-TR criteria, at all time points for females and at age 17 only for males. "Unspecified"/"other" eating disorder diagnoses were significantly less common when applying DSM-5 than DSM-IV-TR criteria, but still formed 15% to 30% of the DSM-5 cases. Diagnostic stability was low for all disorders, and DSM-5 binge eating disorder or purging disorder in early adolescence predicted DSM-5 bulimia nervosa in later adolescence. Cross-over from binge eating disorder to bulimia nervosa was particularly high. Regardless of the diagnostic classification system used, all eating disorder diagnoses were associated with depressive symptoms and poor mental health quality of life. These results provide further support for the clinical utility of DSM-5 eating disorder criteria, and for the significance of binge eating disorder and purging disorder.

    Full Text Available Abstract Background Dizziness is a common complaint among older adults and has been linked to a wide range of health conditions, psychological and social characteristics in this population. However a profile of dizziness is still uncertain which hampers clinical decision-making. We therefore sought to explore the relationship between dizziness and a comprehensive range of demographic data, diseases, health and geriatric conditions, and geriatric syndromes in a representative sample of community-dwelling older people. Methods This is a cross-sectional, population-based study derived from FIBRA (Network for the Study of Frailty in Brazilian Elderly Adults, with 391 elderly adults, both men and women, aged 65 years and older. Elderly participants living at home in an urban area were enrolled through a process of random cluster sampling of census regions. The outcome variable was the self-report of dizziness in the last year. Several feelings of dizziness were investigated including vertigo, spinning, light or heavy headedness, floating, fuzziness, giddiness and instability. A multivariate logistic regression analysis was conducted to estimate the adjusted odds ratios and build the probability model for dizziness. Results The complaint of dizziness was reported by 45% of elderly adults, from which 71.6% were women (p=0.004. The multivariate regression analysis revealed that dizziness is associated with depressive symptoms (OR = 2.08; 95% CI 1.29–3.35, perceived fatigue (OR = 1.93; 95% CI 1.21-3.10, recurring falls (OR = 2.01; 95% CI 1.11-3.62 and excessive drowsiness (OR = 1.91; 95% CI 1.11–3.29. The discrimination of the final model was AUC = 0.673 (95% CI 0.619-0.727 (p Conclusions The prevalence of dizziness in community-dwelling elderly adults is substantial. It is associated with other common geriatric conditions usually neglected in elderly adults, such as fatigue and drowsiness, supporting its possible multifactorial manifestation. Our

    Highlights: • Irreversible swelling of ball-milled MgH{sub 2} is quantified by dilatometry measurements. • The mechanical behavior is strongly dependent of the additive used for ball-milling. • Ball-milled powders evolve from a bi-modal distribution to mono-disperse agglomerates. • The swelling is explained by the lower compacity of the mono-disperse agglomerates. - Abstract: Highly reactive nanostructured powders are produced on a large scale by co-milling of MgH{sub 2} with transition metals. Composite materials with high thermal conductivity are produced by uniaxial compaction of these powders with expanded graphite. However, upon cycling, the MgH{sub 2} grains tend to recrystallize and a progressive swelling of the composites is observed. The purpose of this study is to understand this irreversible phenomenon, through correlations with microstructural evolutions. In-situ dilatometry measurements were performed on samples prepared with 2 different additives (pure vanadium or Ti–V–Cr alloy). We systematically observe a stabilization of the irreversible expansion after about 50 cycles. A bi-modal distribution of the as-milled powders is observed by granulometry measurements. Upon cycling, the coalescence of the “small” MgH{sub 2} particles tends to create large agglomerates and results in mono-disperse powders. This behavior induces an increase in porosity, which explain the progressive swelling of the composites. The maximum of deformation strongly depends on the additive and is lower with vanadium addition than with Ti–V–Cr alloy.

    The present study examined Chinese university students' attitudes toward same-sex attraction and behavior, the socio-demographic correlates of these attitudes, and the potential gender differences in both tendencies and correlates. A total of 2,644 Chinese university students (49.7% male, mean age = 20.27 years) indicated generally negative attitudes toward same-sex attraction and behavior, with males reporting more negative attitudes than females. More years in university (i.e., higher grade levels), higher levels of maternal education, growing up in an urban area, and more frequent Internet use significantly predicted more positive attitudes. Gender significantly moderated one correlate: For female participants, a higher university grade was related to more positive attitudes; this correlation was not significant for male participants. The findings suggest valuable directions for related intervention practices for young people in China.

    Although alcohol consumption is linked to increased aggression, its neural correlates have not directly been studied in humans so far. Based on a comprehensive neurobiological model of alcohol-induced aggression, we hypothesized that alcohol-induced aggression would go along with increased amygdala and ventral striatum reactivity and impaired functioning of the prefrontal cortex (PFC) under alcohol. We measured neural and behavioral correlates of alcohol-induced aggression in a provoking vs non-provoking condition with a variant of the Taylor aggression paradigm (TAP) allowing to differentiate between reactive (provoked) and proactive (unprovoked) aggression. In a placebo-controlled cross-over design with moderate alcohol intoxication (~0.6 g/kg), 35 young healthy adults performed the TAP during functional magnetic resonance imaging (fMRI). Analyses revealed that provoking vs non-provoking conditions and alcohol vs placebo increased aggression and decreased brain responses in the anterior cingulate cortex/dorso-medial PFC (provokingaggression (alcohol × provocation interaction). However, investigation of inter-individual differences revealed (1) that pronounced alcohol-induced proactive aggression was linked to higher levels of aggression under placebo, and (2) that pronounced alcohol-induced reactive aggression was related to increased amygdala and ventral striatum reactivity under alcohol, providing evidence for their role in human alcohol-induced reactive aggression. Our findings suggest that in healthy young adults a liability for alcohol-induced aggression in a non-provoking context might depend on overall high levels of aggression, but on alcohol-induced increased striatal and amygdala reactivity when triggered by provocation.

    2015-01-01

    Full Text Available Prevalence, clinical correlates, and use of glucose-lowering drugs were comprehensively evaluated among 863 nursing home older patients with diabetes (mean age 82.9 ± 2.1 years: functional dependence and cognitive impairment were present in 84.1% and 68% of patients, respectively, and 66.3% of patients had 2–4 comorbidities. HbA1c values < 7.0% were documented in 54.9% of diabetic; significantly lower HbA1c levels were observed in demented patients than in nondemented subjects. Documented hypoglycemic episodes were reported for 57 patients (6.6%, without significant association with age, functional dependence, cognitive impairment, or HbA1c levels. About one-fifth of older long-term facilities residents have diabetes, with concomitant poor health conditions and high prevalence of cognitive impairment and functional dependence. Roughly three-fourths of these older and frail diabetic patients have HbA1c values lower than optimal, suggesting a potential for hypoglycemic harm especially among patients with severe cognitive impairment.

    Although research has documented the prevalence and health correlates of sexual aggression among women who have experienced severe partner violence (PV), no research has documented the parallel issues among male victims of severe PV. Research also suggests that children of female victims of both physical and sexual PV have worse mental health than children of female victims of physical PV only, but no research has assessed the mental health of children whose fathers experienced both physical and sexual PV. We surveyed 611 men who experienced physical PV from their female partners and sought help. We assessed the types and extent of various forms of PV, the men's mental and physical health, and the mental health of their oldest child. Results showed that almost half of the men experienced sexual aggression in their relationship, and 28 % severe sexual aggression. Increasing levels of severity of sexual aggression victimization was associated with greater prevalence and types of other forms of PV. In addition, greater levels of severity of sexual aggression victimization among the men was significantly associated with depression symptoms, post-traumatic stress disorder symptoms, physical health symptoms, and poor health, and attention deficit and affective symptoms among their children. These associations held after controlling for demographics and other violence and trauma exposure. Discussion focused on the importance of broadening our conceptualization of PV against men by women to include sexual aggression as well.

    A multiethnic community sample of 191 families with four-year-old children in northern Norway was used to explore whether parenting factors were associated with child behavior problems, and whether these associations differed for boys and girls or for the two main ethnic groups in this region: the indigenous Sami and the majority Norwegians. The Child Behavior Checklist (CBCL) and a semi-structured interview on child-rearing were used as instruments. As would be expected from a developmental perspective, elevated scores of child behavior problems were associated with lower levels of parental cuddling and with higher levels of physical punishment. Family demographics such as low maternal age and single parenthood were also associated with more behavioral problems. Girls seemed to be more strongly influenced by child-rearing factors than boys. Subgroup analyses suggested that for harsh treatment, patterns of correlations differed between Sami and Norwegian groups, especially for boys. A positive correlation between physical punishment and externalizing problems emerged for Norwegian boys, but not for Sami boys. Teasing/ridiculing was positively correlated with internalizing problems for Norwegian boys, but inversely correlated for Sami boys. These findings emphasize the importance of taking the child's cultural context and gender into account when assessing parenting influences on behavioral problems in children.

    We demonstrate that single-photon as well as biphoton revivals are possible in a new class of dynamic optical systems-the so-called Glauber-Fock oscillator lattices. In these arrays, both Bloch-like oscillations and dynamic delocalization can occur which can be described in closed form. The bunching and anti-bunching response of path-entangled photons can be pre-engineered in such coupled optical arrangements and the possibility of emulating Fermionic behavior in this family of lattices is also considered. We elucidate these effects via pertinent examples and we discuss the prospect of experimentally observing these quantum interactions.

    Chlamydiosis is a zoonotic disease caused by Chlamydia psittaci that occurs in a wide range of bird species. High infection rates with C. psittaci are found in pigeons, which can act as vectors transmitting this bacterium to poultry and humans. Chlamydia shedding by pigeons is intermittent and can be activated by stressors or immunosuppression. The most common immunosuppressive factor for pigeons is a pigeon circovirus (PiCV) infection. The main aim of the study was to evaluate the prevalence of C. psittaci in Polish populations of domestic and feral pigeons (Columba livia) in the context of its correlation with PiCV infections. The second objective was to determine the genetic characteristics of Polish C. psittaci isolates. The study was conducted on 377 pigeon samples (276 domestic and 101 feral pigeons) collected from pigeons from different regions of Poland. The average prevalence of C. psittaci in the Polish pigeon population was determined at 6.8%, and it was higher in domestic than in feral pigeons. This is the first ever study to suggest a potential correlation between C. psittaci and PiCV infections, which could be attributed to the fact that there are 2 to 3 times more pigeons infected with C. psittaci and coinfected with PiCV than pigeons infected with C. psittaci alone. This trend was observed mainly in the population of sick pigeons. As many as 88.2% of isolates were recognized as belonging to genotype B, and the remaining isolates were identified as belonging to genotype E. The isolates analyzed in this study demonstrated low levels of genetic variation (96-100% homology among the isolates and in relation to reference strains). Chlamydia psittaci could be expected to spread across pigeon populations due to the high probability of mutual infections between birds and the increasing number of PiCV infections.

    Objectives Despite the vast quantity of research among Chinese female sex workers (FSWs) to address concerns regarding HIV/sexually transmitted infection (STI) risk, there is a paucity of research on issues of sexual and gender-based violence (SGBV) and the missed opportunity for sexual and reproductive health (SRH) promotion among young FSWs. Our research aimed to assess the prevalence and correlates of SGBV among Chinese adolescent FSWs, and to explore SRH service utilisation. Design and methods A cross-sectional study using a one-stage cluster sampling method was employed. A semistructured questionnaire was administered by trained peer educators or health workers. Multivariable logistic regression was conducted to determine individual and structural correlates of SGBV. Setting and participants Between July and September 2012, 310 adolescent women aged 15–20 years, and who self-reported having received money or gifts in exchange for sex in the past 6 months were recruited and completed their interview in Kunming, Yunnan Province, China. Results Findings confirm the high prevalence of SGBV against adolescent FSWs in China, with 38% (118/310) of participants affected in the past year. Moreover, our study demonstrated the low uptake of public health services and high rates of prior unwanted pregnancy (52%; 61/118), abortion (53%; 63/118) and self-reported STI symptoms (84%; 99/118) in participants who were exposed to SGBV. Forced sexual debut was reported by nearly a quarter of FSWs (23%; 70/310) and was independently associated with having had a drug-using intimate partner and younger age (abortion. When controlling for potential confounders, having experienced SGBV was associated with frequent alcohol use, having self-reported symptoms of STI, having an intimate partner and having an intimate partner with illicit drug use. Conclusions This study calls for effective and integrated interventions addressing adolescent FSWs' vulnerability to SGBV and broader SRH

    Objectives: A physically active lifestyle is important for cancer survivors. Therefore, this study was conducted to 1) provide population-based estimates of the prevalence of physical activity and sitting time, and 2) their correlates in Korean cancer survivors. Materials and Methods: This study analyzed a cancer survivor subsample (N=1,482) from 2008-2013 Korea National Health and Nutrition Examination Survey (KNHANES), data selected with a complex sampling design. Overall and subgroup-specific prevalences of physical activity and sitting time were estimated. Correlates of moderate- to vigorous-intensity physical activity ( MVPA) and sitting time were tested using age-groupspecific hierarchical multiple regression models. Results: Overall adherence rate to physical activity guidelines was 34.9% (95% CI=31.5-38.4). Age-group-specific adherence rates were 41.1% (95% CI=36.3-45.9) in adults (30-64 years old), and 25.3% (95% CI=21.0-25.3) in older adults (65 years or older). Adults spent 213.33 minutes (95% CI=172.4-254.3) per week on MVPA and 55.3 minutes (95% CI=36.4-64.6) on sitting time per day. In adults, sitting time was significantly associated with employed status (B=28.0, p=0.046), smoking (B=-47.4, p=0.020), and number of comorbidity conditions (B=-13, p=.037). MVPA was significantly associated with marital status (B=134.9, pphysical activity. In general, older, unhealthier, non-working, and being unmarried were risk factors for physical inactivity. While this study informs public health policy makers and practitioners about physical activity intervention demand for cancer survivors, future investigations should address psychosocial mediators to better inform intervention programs.

    Full Text Available Correlation equations for expressing the boiling temperature as direct function of liquid composition have been tested successfully and applied for predicting azeotropic behavior of multicomponent mixtures and the kind of azeotrope (minimum, maximum and saddle type using modified correlation of Gibbs-Konovalov theorem. Also, the binary and ternary azeotropic point have been detected experimentally using graphical determination on the basis of experimental binary and ternary vapor-liquid equilibrium data.In this study, isobaric vapor-liquid equilibrium for two ternary systems: “1-Propanol – Hexane – Benzene” and its binaries “1-Propanol – Hexane, Hexane – Benzene and 1-Propanol – Benzene” and the other ternary system is “Toluene – Cyclohexane – iso-Octane (2,2,4-Trimethyl-Pentane” and its binaries “Toluene – Cyclohexane, Cyclohexane – iso-Octane and Toluene – iso-Octane” have been measured at 101.325 KPa. The measurements were made in recirculating equilibrium still with circulation of both the vapor and liquid phases. The ternary system “1-Propanol – Hexane – Benzene” which contains polar compound (1-Propanol and the two binary systems “1-Propanol – Hexane and 1-Propanol – Benzene” form a minimum azeotrope, the other ternary system and the other binary systems do not form azeotrope.All the data passed successfully the test for thermodynamic consistency using McDermott-Ellis test method (McDermott and Ellis, 1965.The maximum likelihood principle is developed for the determination of correlations parameters from binary and ternary vapor-liquid experimental data which provides a mathematical and computational guarantee of global optimality in parameters estimation for the case where all the measured variables are subject to errors and the non ideality of both vapor and liquid phases for the experimental data for the ternary and binary systems have been accounted.The agreement between prediction and experimental data is

    It is well known that chloroplasts move in response to changes in blue light intensity in order to optimize light interception, however, little is known about interspecific variation and the relative importance of this mechanism for the high light stress tolerance of plants. We characterized chloroplast movement behavior as changes in light transmission through a leaf in a variety of species ranging from ferns to monocots and eudicots and found a wide spectrum of responses. Most species exhibited a distinct accumulation response compared to the dark positioning, and all species showed a distinct avoidance response. The speed with which transmission values changed during the avoidance response was consistently faster than that during the accumulation response and speeds varied greatly between species. Plants thriving in higher growth light intensities showed greater degrees of accumulation responses and faster changes in transmission than those that prefer lower light intensities. In some species, the chloroplasts on both the adaxial and abaxial leaf surfaces changed their positioning in response to light, while in other species only the chloroplasts on one leaf side responded. No correlation was found between high light stress tolerance and the speed or degree of transmission changes, indicating that plants can compensate for slow and limited transmission changes using other photoprotective mechanisms.

    The forced swim test (FST) is widely used to evaluate the antidepressant-like activity of compounds and is sensitive to stimuli that cause depression-like behaviors in rodents. The immobility behavior observed during the test has been considered to represent behavioral despair. In addition, some studies suggest that the FST impairs rats' performance on cognitive tests, but these findings have rarely been explored. Thus, we investigated the effects of the FST on behavioral tests related to neuropsychiatric diseases that involve different cognitive components: novel object recognition (NOR), the object location test (OLT) and prepulse inhibition (PPI). Brain-derived neurotrophic factor (BDNF) levels in the frontal cortex and hippocampus were evaluated. The rats were forced to swim twice (15-min session followed by a 5-min session 24h later) and underwent cognitive tests 24h after the last swimming exposure. The FST impaired the rats' performance on the OLT and reduced the PPI and acoustic startle responses, whereas the NOR was not affected. The cognitive impairments were not correlated with an immobility behavior profile, but a significant negative correlation between the frontal BDNF levels and immobility behavior was identified. These findings suggest a protective role of BDNF against behavioral despair and demonstrate a deleterious effect of the FST on spatial memory and pre-attentive processes, which point to the FST as a tool to induce cognitive impairments analogous to those observed in depression and in other neuropsychiatric disorders.

  2. Is the HIV epidemic stable among MSM in Mexico? HIV prevalence and risk behavior results from a nationally representative survey among men who have sex with men.

    Directory of Open Access Journals (Sweden)

    Sergio Bautista-Arredondo

    Full Text Available BACKGROUND: Recent evidence points to the apparent increase of HIV prevalence among men who have sex with men (MSM in different settings with concentrated epidemics, including the Latin American region. In 2011, Mexico implemented an ambitious HIV prevention program in all major cities, funded by the Global Fund to Fight Aids, Tuberculosis and Malaria. The program was intended to strengthen the prevention response for the most at risk populations: MSM and injecting drug users. This paper presents the HIV prevalence results of a nationally representative baseline survey in 24 Mexican cities throughout the 5 regions in the country and reports the socio-demographic and sexual risk behaviors that predict the probability of infection. METHODS: The survey was implemented in two phases. We first identified and characterized places where MSM gather in each city and then conducted in a second phase, a seroprevalence survey that included rapid HIV testing and a self-administered questionnaire. The prevalence of HIV was estimated by adjusting for positive predicted value. We applied a probit model to estimate the probability of having a positive result from the HIV test as a function of socio-demographic characteristics and self-reported sexual risk behaviors. RESULTS: We found an overall HIV prevalence among MSM gathering in meeting points of 16.9% [95% CI: 15.6-18.3], significantly higher than previously reported estimates. Our regression results suggest that the risk of infection increases with age, with the number of sexual partners, and among those who play a receptive sexual role, and the risk decreases with higher education. DISCUSSION: Our findings suggest a higher HIV prevalence among MSM than previously acknowledged and that a significant regional variability exist throughout the country. These two findings combined, signal an important dynamic in the epidemic that should be better understood and promptly addressed with strong prevention efforts

After correction for multiple comparisons testing, genetic variation in the vitamin D pathway was not found to associate with serum 25(OH)D concentration or clinical correlates of COPD severity. Vitamin D deficiency was common in this group of COPD patients in the UK, and it associated independently with reduced % predicted FEV1 and FVC. However, genetic variation in the vitamin D pathway was not associated with vitamin D status or severity of COPD.

    Full Text Available BACKGROUND: Depression is a leading contributor to the burden of disease worldwide, a critical barrier to HIV prevention and a common serious HIV co-morbidity. However, depression screening and treatment are limited in sub-Saharan Africa, and there are few population-level studies examining the prevalence and gender-specific factors associated with depression. METHODS: We conducted a cross-sectional population-based study of 18-49 year-old adults from five districts in Botswana with the highest prevalence of HIV-infection. We examined the prevalence of depressive symptoms, using a Hopkins Symptom Checklist for Depression (HSCL-D score of ≥ 1.75 to define depression, and correlates of depression using multivariate logistic regression stratified by sex. RESULTS: Of 1,268 participants surveyed, 25.3% of women and 31.4% of men had depression. Among women, lower education (adjusted odds ratio [AOR] 2.07, 95% confidence interval [1.30-3.32], higher income (1.77 [1.09-2.86], and lack of control in sexual decision-making (2.35 [1.46-3.81] were positively associated with depression. Among men, being single (1.95 [1.02-3.74], living in a rural area (1.63 [1.02-2.65], having frequent visits to a health provider (3.29 [1.88-5.74], anticipated HIV stigma (fearing discrimination if HIV status was revealed (2.04 [1.27-3.29], and intergenerational sex (2.28 [1.17-4.41] were independently associated with depression. DISCUSSION: Depression is highly prevalent in Botswana, and its correlates are gender-specific. Our findings suggest multiple targets for screening and prevention of depression and highlight the need to integrate mental health counseling and treatment into primary health care to decrease morbidity and improve HIV management efforts.

    Background: Rapid eye movement (REM) sleep behavior disorder (RBD) may be a risk factor for cognitive impairment in patients with Parkinson's disease (PD).However, little is known regarding the relation between the severity of RBD and the different domains of cognitive impairment.The aim of this study was: (1) to investigate the domains of cognitive impairment in patients with PD and RBD, and (2) to explore risk factors for PD-mild cognitive impairment (PD-MCI) and the relationship between RBD severity and impairment in different cognitive domains in PD.Methods: The participants were grouped as follows: PD without RBD (PD-RBD;n =42), PD with RBD (PD + RBD;n =32), idiopathic RBD (iRBD;n =15), and healthy controls (HCs;n =36).All participants completed a battery of neuropsychological assessment of attention and working memory, executive function, language, memory, and visuospatial function.The information of basic demographics, diseases and medication history, and motor and nonmotor manifestations was obtained and compared between PD-RBD and PD + RBD groups.Particular attention was paid to the severity of RBD assessed by the RBD Questionnaire-Hong Kong (RBDQ-HK) and the RBD Screening Questionnaire (RBDSQ), then we further examined associations between the severity of RBD symptoms and cognitive levels via correlation analysis.Results: Compared to PD-RBD subjects, PD + RBD patients were more likely to have olfactory dysfunction and their Epworth Sleepiness Scale scores were higher (P < 0.05).During neuropsychological testing, PD + RBD patients performed worse than PD-RBD patients, including delayed memory function, especially.The MCI rates were 33%, 63%, 33%, and 8% for PD-RBD, PD + RBD, iRBD, and HC groups, respectively.RBD was an important factor for the PD-MCI variance (odds ratio =5.204, P =0.018).During correlation analysis, higher RBDSQ and RBDQ-HK scores were significantly associated with poorer performance on the Trail Making Test-B (errors) and

    Complex marine benthic environments shape a number of ecologically important behaviors in sea urchins, including covering and righting behaviors. The present study correlated covering and righting behaviors to a series of fitness-related traits in sea urchins. Righting response time of Glyptocidaris crenularis was significantly positively correlated with body size, but significantly negatively correlated with food consumption. Covering behavior was not significantly correlated with test diameter, test height or body weight, but covering response time was negatively correlated with body weight. A significantly negative correlation was found between righting response time and covering response time. Glyptocidaris crenularis showed a significantly positive correlation in covering response time with and without exposure to poured sand, but no significance in covering ability (number of shells used to cover). The present study provides new insight into internal mechanisms and evolutionary drives of covering and righting behaviors of sea urchins.
