    Runacres, Sean A; Wood, Paul L

    2016-06-01

    Labiaplasty (defined as the surgical reduction of the labia minora) is the most common procedure under the umbrella of female genital cosmetic surgery with the prevalence increasing over the past 10-15 years. However, the concept of labial hypertrophy holds an arbitrary definition, with no research into labial size undertaken within the pediatric and adolescent populations. Under the tenets of medical ethics there is acceptance of the need to avoid harm and so, for reasons to be outlined, performance of labiaplasty in children and adolescents should be avoided. This Mini-Review does not extend to pathological conditions that affect the labia minora. PMID:26453828

    2009-11-01

    Full Text Available Introduction: Terminal renal failure affects all aspects of the person’s life. The impact of this illness during the adolescence is quite dramatic since the adolescent must overcome the demands from the developmental stage and the illness situation. Knowledge about the illness impact on the adolescents´life is scarce; as a contribution to increasing this knowledge, a study was done to describe the lived experiences of adolescents in dialysis. Methodology: The study is qualitative; the methodological strategy used was interpretive phenomenolgy based on Heidegger´s phylosophy. Findings: Adolescents in dialysis experienced losses in their everyday life, especially as students; they also experienced loss of their independence, their previous body image and their desirable body image. The imposed and rigid timetables for the pharmacological treatment and dialysis procedure, the dialysis catheter and the diet restrictions are the main causes of their losses. Peer relationships deteriorated due to the social isolation the adolescents imposed on themselves as a way to cope with the losses. Renal transplant is perceived as a mean to recover all they have lost. Conclusion: Knowledge generated by this study would contribute to provide health care more congruent with the adolescents’ everyday needs.

    1991-01-01

    The problem of the effect of population growth on subsistence conditions is addressed by developing generalized premises, principles, and methods for quantifying standards or conditions for growth. This method is applied to 1989 data for Nanzheng Country, China. Background information is provided on an experiment made public in 1985 and implemented in 1986 by the Family Planning (FP) Department of Nanzheng County of Shaanxi Province in Hongmiao District in which the following conditions were placed on bearing a second child: 1) income must be 20% higher than the average village income level, and breeders must have an average income of not 400 yuan/year, crop planters not 300 yuan/year, textile weavers not 200 yuan/year, and industrial and subsidiary production workers not 400 yuan/year (generally 4 pigs or 100 chickens or ducks) or 2) 100 income-producing trees must be planted around he residential area/family plot or stony fields must be transformed into arable land under the contract responsibility system, or groves, orchards, or tea plantations must be planted. These conditions must be met one year prior to proposing to have a second child. The approval rate in 1986-88 was 88.7%, and the second parity rate was 78.4%. Deteriorated conditions had not yet occurred in this country when this proposal was made. The premises considered important in preparing assistance conditions were determined. 1) Conditions for population growth should be resolved within the area. 2) Subsistence conditions should be taken care of by the family. 3) There should be a centralized standard, not a family standard, such that living conditions/capita should not decrease because of population growth. Quantification is made expressing the relationship between subsistence and growth. The application of these conditions for households in Hongmiao District is that the average subsistence conditions need to be higher than other households by 12.3% for new population growth. The assumption is

    Treatment for adolescents with sexually maladaptive behaviors is a continuing intervention that is changing and developing as greater understanding about this population of adolescents is obtained. The majority of treatment programs for adolescent sexually maladaptive behavior contain programming components that include cognitive distortions/thinking errors. Interviews including a conceptual mapping exercise were conducted with four adolescents adjudicated to a secure care program for sexual behaviors. All four boys completed an interview and a conceptual map of their perceived experiences as an adolescent with sexual maladaptive behaviors. All interviews were audio recorded. Analysis of the interviews and conceptual mappings yielded five themes present in the boys' experience as well as a consideration of the role early trauma may have in the establishment of cognitive distortion development. Contributing environmental and familial factors also play an important part in sustaining cognitive distortion. Main themes include: loss of responsible father or father figure, inability to regulate emotion, lack of personal and parental boundaries, and early exposure to pornography. The contributing influence of responsible male father figures may play an even greater role in the lives of young males than originally thought. How the adolescent inaccurately perceives his environment--in essence what he tells himself and continues to tell himself to make sense of his world--are building blocks in the development and continuation of thinking errors/cognitive distortions used to commit and justify sexual offending behaviors.

    This article discusses a 3-year project, "Promotion of Adolescent Reproductive Health and Healthy Living," which was implemented by the Federation of Family Planning Associations, Malaysia. The project seeks to achieve the following: 1) development of a reproductive health of adolescent module (RHAM) for trainers and educators; 2) training of trainers; 3) sharing of adolescent reproductive health experiences in Asian countries; and 4) setting up three service models in Sabah, Selangor, and Terengganu to provide reproductive health (RH) care to adolescents and youth. The first part of the RHAM with the trainer's manual has been finalized and will be tested in a workshop. The second part, a teacher's guide, is under preparation. A series of training on the use of the RHAM will be conducted including a 5-day national workshop, which will be followed by several state level workshops. The three service models being set up have specific orientations. The Sabah model is putting up a youth clinic for adolescents within its clinic network. The Selangor model is developing a Youth Resource Center for training and youth involvement in RH activities. Lastly, the Terengganu family planning association (FPA) has developed a Youth Center web site, which features the history, mission, and activities of the Terengganu FPA. PMID:12158246

  18. Persistence of the Intuitive Conception of Living Things in Adolescence

    Science.gov (United States)

    Babai, Reuven; Sekal, Rachel; Stavy, Ruth

    2010-02-01

    This study investigated whether intuitive, naive conceptions of "living things" based on objects' mobility (movement = alive) persist into adolescence and affect 10th graders' accuracy of responses and reaction times during object classification. Most of the 58 students classified the test objects correctly as living/nonliving, yet they demonstrated significantly longer reaction times for classifying plants compared to animals and for classifying dynamic objects compared to static inanimate objects. Findings indicated that, despite prior learning in biology, the intuitive conception of living things persists up to age 15-16 years, affecting related reasoning processes. Consideration of these findings may help educators in their decisions about the nature of examples they use in their classrooms.

    2008-12-01

    I analyze the effects of Catholic schooling, Protestant schooling, and homeschooling on adolescents' religious lives and test three mechanisms through which these schooling strategies might influence religiosity: friendship networks, network closure, and adult mentors. Data from Wave 1 of the National Survey of Youth and Religion suggest that Catholic schoolers attend religious services more frequently and value their faith more highly than public schoolers, but attend religious education classes and youth group less often. Protestant schoolers' involvement in their local congregation is similar to public schoolers', but their faith plays a more salient role in their life and they are more active in private religious activities. Homeschoolers do not differ significantly from public schoolers on any outcome considered. Moreover, friendship networks, network closure, and adult mentors play a very limited role in mediating the relationships between schooling strategies and adolescent religiosity. Interpretations of these findings are presented and discussed. PMID:21709822

    2016-06-01

    This study purports to address paucity in the literature regarding how adolescents with sickle cell disease (SCD) describe and experience spirituality and religiosity (S/R). This was a qualitative descriptive study. Two semi-structured interviews were conducted with nine adolescents (Mage = 16.2 years). Data were analyzed using a template analysis style and a concurrent analysis process of data reduction. Three major themes encompassed the participants' descriptions of the relationships between S/R, health and illness in their lives including S/R as sources for coping, influence of S/R beliefs on health and illness, and sharing S/R with Health Care Providers (HCPs). S/R as coping mechanisms included six threads: interconnecting with God, interconnecting with others, interconnecting with creative arts, scriptural metanarratives, transcendent experiences, and acceptance and finding meaning. Expectations of health providers included two threads: Religiosity is private/personal and sharing spiritual and religious beliefs is risky. S/R are particularly salient for adolescents with SCD.

    2011-05-01

    Effortful control is thought to foster adaptive action in defensive contexts and may thereby protect individuals against anxious inhibition and focus on their own distress. We examined if effortful control predicted adolescents' perceived arousal, unpleasantness, and control as well as autonomic (heart rate [HR]) and hypothalamic-pituitary-adrenal axis (cortisol) responses during social stress. The data came from a focus sample of the Tracking Adolescents' Individual Lives Survey, a prospective population study of Dutch adolescents (N = 715, 50.9% girls; mean age = 16.11, SD = 0.59), who participated in a laboratory session including a social stress task (public speaking and mental arithmetic). Perceived and physiological stress measures were assessed before, during, and after the social stress task. Effortful control was measured using various questionnaires and informants, as well as by means of a reaction time (RT) task assessing response inhibition. Overall, adolescents with high questionnaire-based effortful control tended to feel more relaxed, pleasant, and in control during the laboratory session than adolescents with lower levels of control and had stronger HR responses to the stress test. Adolescent girls with high inhibitory control as measured by the RT task also had strong HR responses, but inhibitory control was associated with high rather than low perceived arousal. Our results suggest that both questionnaire and RT measures of effortful control predict strong HR responses to challenging situations, but associational patterns diverge with regard to perceived stress measures.

    Growing sexuality among adolescents increases their risk of getting reproductive tract infections and pregnancy. This Cross sectional survey was done to assess the knowledge and attitude of higher secondary school children regarding contraception and population control. Majority of students (94.4%) were aware of contraceptives and their easy availability on chemist shop. However very few were aware of name and how to use them and 60% of them considered that condom is an emergency contraceptive. Lack of employment facilities as a consequence of uncontrolled population growth was the main concern of both boys and girls. The two children norm was acceptable to most, with one son and one daughter. All perceived that there is need to be informed about contraceptives. Most of the adolescents are misinformed about contraceptives and their attitude is not favorable as far as responsibility is concerned. There is an unmet need of contraceptive & population control knowledge and attitude among school adolescents and require urgent intervention. PMID:20803909

    This study aimed to (i) assess the prevalence and perceived need for treatment of TMD pain, and its association with socio-economic factors and gender, in adolescents in Xi᾽an, Shaanxi Province, China, and (ii) compare the prevalence and association with gender of TMD pain in Xi᾽an to an age-matched Swedish population. We surveyed Chinese adolescents aged 15 to 19 years in Xi'an, China (n = 5524), using a questionnaire with two-stage stratified sampling and the school as the sampling unit. The study included second-year students at selected high schools. It also included an age-matched Swedish population (n = 17 015) surveyed using the same diagnostic criteria for TMD pain as that used in the Chinese sample. The survey found TMD pain in 14·8% (n = 817) of the Chinese sample and 5·1% (n = 871) of the Swedish sample (P < 0·0001). Girls had significantly more TMD pain than boys in both the Chinese (P < 0·05) and Swedish (P < 0·001) samples. TMD pain increased with age in the Chinese population. Of the Chinese adolescents with TMD pain, 47% reported that they felt a need for treatment. Rural schools, low paternal education levels, poverty, living outside the home, poor general and oral health, and dissatisfaction with teeth all showed significant positive correlations with TMD pain. Prevalence of TMD pain in Chinese adolescents was significantly higher than in the Swedish sample. PMID:26538188

    For most children and adolescents who have developed symptomatic scars, cosmetic concerns are only a portion of the motivation that drives them and their caregivers to obtain treatment. In addition to the potential for cosmetic disfigurement, scars may be associated with a number of physical comorbidities including hypertrichosis, dyshidrosis, tenderness/pain, pruritus, dysesthesias, and functional impairments such as contractures, all of which may be compounded by psychosocial factors. Although a plethora of options for treating scars exists, specific management guidelines for the pediatric and adolescent populations do not, and evidence must be extrapolated from adult studies. New modalities such as the scar team approach, autologous fat transfer, and ablative fractional laser resurfacing suggest a promising future for children who suffer symptomatically from their scars. In this state-of-the-art review, we summarize cutting-edge scar treatment strategies as they relate to the pediatric and adolescent populations. PMID:26743819

    The present study aimed to examine the factors associated with increased Mediterranean diet (MD) adherence among a sample of Italian adolescents. A cross-sectional survey was conducted on 1135 students (13-16 years) attending 13 secondary schools of Sicily, southern Italy. Validated instruments were used for dietary assessment and the KIDMED score to assess adolescents' adherence to the MD. A higher adherence to the MD was associated with high socioeconomic status (Odds Ratio [OR] 1.53, 95% Confidence Interval [CI]: 1.03-2.26) and high physical activity (OR 1.19, 95% CI: 1.02-1.70), whereas lower adherence was associated with living in an urban environment (OR 0.65, 95% CI: 0.44-0.97) and being obese (OR 0.59, 95% CI: 0.37-0.94). The adolescents' KIDMED scores were inversely associated with adolescents' intake of sweets, fast foods, fried foods, and sugary drinks, and directly with fruit, vegetables, pasta, fish, and cheese intakes. Urban-living adolescents were less likely to eat fruit and more prone to consume meat, sugary drinks, and fast food than rural-living adolescents. The latter were more likely to eat sweets and snacks. A general poor quality of food consumption in Italian adolescents away from the MD was reported, especially among those living in urban areas.

    Full Text Available Background: Resilience is one of the main factors affecting human health, and perceiving its meaning for high-risk adolescents is of particular importance in initiating preventive measures and providing resilience care. Objectives: This qualitative study was conducted to explain the meaning of resilience in the lived experiences of Iranian adolescents living in governmental residential care facilities. Materials and methods: This study was conducted using the hermeneutic phenomenological method. Semi-structured interviews were conducted with eight adolescents aged 13–17 living in governmental residential care facilities of Tehran province affiliated to the Welfare Organization of Iran who articulated their experiences of resilience. Sampling lasted from May 2014 to July 2015 and continued until new themes were no longer emerging. The researchers analyzed the verbatim transcripts using Van Manen's six-step method of phenomenology. Results: The themes obtained in this study included “going through life's hardships,” “aspiring for achievement,” “self-protection,” “self-reliance,” and “spirituality.” Conclusion: Our study indicates that the meaning of resilience coexists with self-reliance in adolescents’ lived experiences. Adolescents look forward to a better future. They always trust God in the face of difficulties and experience resilience by keeping themselves physically and mentally away from difficulties. Adverse and bitter experiences of the past positively affected their positive view on life and its difficulties and also their resilience. The five themes that emerged from the findings describe the results in detail. The findings of this study enable nurses, health administrators, and healthcare providers working with adolescents to help this vulnerable group cope better with their stressful life conditions and improve their health through increasing their capacity for resilience.

    Full Text Available Introduction: Avoiding unintended pregnancies is important for the health of adolescents living with HIV and has the additional benefit of preventing potential vertical HIV transmission. Health facility providers represent an untapped resource in understanding the barriers and facilitators adolescents living with HIV face when accessing contraception. By understanding these barriers and facilitators to contraceptive use among adolescent females living with HIV, this study aimed to understand how best to promote contraception within this marginalized population. Methods: We conducted structured in-depth interviews with 40 providers at 21 Family AIDS Care & Education Services - supported clinics in Homabay, Kisumu and Migori counties in western Kenya from July to August 2014. Our interview guide explored the providers’ perspectives on contraceptive service provision to adolescent females living with HIV with the following specific domains: contraception screening and counselling, service provision, commodity security and clinic structure. Transcripts from the interviews were analyzed using inductive content analysis. Results: According to providers, interpersonal factors dominated the barriers adolescent females living with HIV face in accessing contraception. Providers felt that adolescent females fear disclosing their sexual activity to parents, peers and providers, because of repercussions of perceived promiscuity. Furthermore, providers mentioned that adolescents find seeking contraceptive services without a male partner challenging, because some providers and community members view adolescents unaccompanied by their partners as not being serious about their relationships or having multiple concurrent relationships. On the other hand, providers noted that institutional factors best facilitated contraception for these adolescents. Integration of contraception and HIV care allows easier access to contraceptives by removing the stigma of coming

    Despite an increased risk of mental health problems in adolescents with autism spectrum disorder (ASD), there is limited research on effective prevention approaches for this population. Funded by the Cooperative Research Centre for Living with Autism, a theoretically and empirically supported school-based preventative model has been developed to alter the negative trajectory and promote wellbeing and positive mental health in adolescents with ASD. This conceptual paper provides the rationale, theoretical, empirical and methodological framework of a multilayered intervention targeting the school, parents and adolescents on the spectrum. Two important interrelated protective factors have been identified in community adolescent samples, namely the sense of belonging (connectedness) to school and the capacity for self and affect regulation in the face of stress (i.e. resilience). We describe how a confluence of theories from social psychology, developmental psychology and family systems theory, along with empirical evidence (including emerging neurobiological evidence), supports the interrelationships between these protective factors and many indices of wellbeing. However, the characteristics of ASD (including social and communication difficulties, and frequently difficulties with changes and transitions, and diminished optimism and self-esteem) impair access to these vital protective factors. The paper describes how evidence-based interventions at the school level for promoting inclusive schools (using the Index for Inclusion) and interventions for adolescents and parents to promote resilience and belonging [using the Resourceful Adolescent Program (RAP)] are adapted and integrated for adolescents with ASD. This multisite proof-of-concept study will confirm whether this multilevel school-based intervention is promising, feasible and sustainable. PMID:27072681

    Introduction There is a strong evidence base that the stigma, discrimination and criminalization affecting adolescent key populations (KPs) aged 10–17 is intensified due to domestic and international legal constructs that rely on law-enforcement-based interventions dependent upon arrest, pre-trial detention, incarceration and compulsory “rehabilitation” in institutional placement. While there exists evidence and rights-based technical guidelines for interventions among older cohorts, these gu...

    Adolescents found within single-parent families without a residential father have reported higher levels of sexual debut and higher levels of reported pregnancy. Using data from the Mobile Youth Survey, the purpose of this study is to determine the impact of the presence of a father figure on the sexual debut of African-American adolescents living in poverty and to determine if gender moderates the relationship between the presence of a father figure and sexual debut. Additionally, this study will examine the family processes in which the presence of a father figure can affect the sexual debut of African-American adolescents who live within economically and socially disadvantaged communities. The results revealed that African-American adolescents reporting a father figure had lower rates of sexual debut than those youth reporting no father figure. Gender was not found to be a significant moderator in the relationship between father figure presence and sexual debut. However, existing curfews and family rules did account for some of the effects of presence of a father figure and sexual debut. The results suggest that when adolescents have a father figure in their lives, it may reduce the possibility of early sexual debut. PMID:25582779

    Full Text Available Aims: From the developmental perspectives children acquire and widen their perceptions of health as they mature and grow up. The main purpose of this study was to describe health through the eyes of adolescents in immigrant Ethiopian families living in Finland.Methods: Ten boys and five girls participated. The adolescents’ ages ranged from 12 to17. Theme interviews were used in data collection. Snowball sampling technique was used. Consent was obtained from the adolescents and adolescents’ parents. Inductive content analysis technique was used to analyse the data.Results: Adolescents indicated that health is the wellbeing of all dimensions that make us intact and complete. Adolescents believed relaxation, physical activity, good hygiene, good social relationship, avoiding consumption of poison substances, green nature, hygienic environment and peace are health supportive elements. On the contrary adolescents said insufficient resting, violent behaviors, difficulty, irritation, being inactive physically, addiction to alcohol and smoking, eating fatty food, not respecting meal time and use of drugs are health damaging behaviors. Adolescents consumed soft drink and alcohol frequently ,were physical inactive, practiced unhealthy eating habits, felt lazy to go and grab food from food store, faced financial difficulty to pay for Gym and healthy food that threatened their health. Adolescents used sport, socialization, moderate alcohol intake, avoid eating unhealthy food and smoking as their strategies to enhance their health.Conclusions: Adolescents were able to identify unhealthy lifestyles and healthy lifestyles. However adolescents were engaged in healthy and unhealthy lifestyles simultaneously. Thus family, school, neighbours and health care workers should work together and vigilant in assessing and removing factors that prevent adolescents from adopting healthy lifestyles.

    Full Text Available The present study aimed to examine the factors associated with increased Mediterranean diet (MD adherence among a sample of Italian adolescents. A cross-sectional survey was conducted on 1135 students (13–16 years attending 13 secondary schools of Sicily, southern Italy. Validated instruments were used for dietary assessment and the KIDMED score to assess adolescents’ adherence to the MD. A higher adherence to the MD was associated with high socioeconomic status (Odds Ratio [OR] 1.53, 95% Confidence Interval [CI]: 1.03–2.26 and high physical activity (OR 1.19, 95% CI: 1.02–1.70, whereas lower adherence was associated with living in an urban environment (OR 0.65, 95% CI: 0.44–0.97 and being obese (OR 0.59, 95% CI: 0.37–0.94. The adolescents’ KIDMED scores were inversely associated with adolescents’ intake of sweets, fast foods, fried foods, and sugary drinks, and directly with fruit, vegetables, pasta, fish, and cheese intakes. Urban-living adolescents were less likely to eat fruit and more prone to consume meat, sugary drinks, and fast food than rural-living adolescents. The latter were more likely to eat sweets and snacks. A general poor quality of food consumption in Italian adolescents away from the MD was reported, especially among those living in urban areas.

    The ongoing existence of institutionalized racism and discriminatory practices in various systems (education, criminal justice, housing, employment) serve as root causes of poor health in Blacks Lives. Furthermore, these unjust social structures and their complex interplay result in inefficient utilization of health services and reactive or futile interactions with medical providers. Collectively, these factors contribute to racial disparities in health and treatment represents a significant portion of the nation's health care expenditures. In order for health care systems to optimize population health goals, racism must be recognized as a determinant of health. As anchor institutions in their respective communities, we offer hospitals and health systems a conceptual framework to address the issue within internal and external constructs. PMID:27372475

    This article summarizes the activities at the ESCAP Population Division Expert Group Meeting on Adolescents that was held during September-October 1997 in Bangkok, Thailand. The meeting was a follow-up to the 1994 International Conference on Population and Development (ICPD). The meeting considered 1) the ICPD recommendations; 2) the recommendations contained in the Jakarta Plan of Action on Human Resource Development; and 3) the Proposals for Action on Human Resources Development for Youth in Asia and the Pacific. Participants included about 25 people from Australia, Bangladesh, China, India, Indonesia, Philippines, Sri Lanka, and Thailand. The conference relied on 8 invited experts, two resource persons, advisors from the UNFPA Country Support Team for East and Southeast Asia, and representatives of UNFPA, the Population Council, and the East-West Center. A concern was the declining age of menarche of girls in the ESCAP region and the increasing age of marriage. During the time of menarche and marriage, girls are migrating and moving away from their family and community in rural areas. Family structure and relationships are changing. Increases are observed in adolescent premarital sexual activity, the incidence of sexually transmitted diseases, substance abuse, teenage pregnancy, and abortion. The mass media and information technologies have both a positive and a negative influence on adolescents. Parent-child communication exchanges and teacher-student exchanges are "less than ideal." Old traditions and practices change slower than people change. Boys and girls are affected differently by the sociocultural and economic environment. The societal norms set expectations for behavior that may conflict with individual beliefs and practices. Changes brought by globalization and rapid economic growth provide greater opportunity for young girls and women to obtain employment and autonomy. PMID:12293003

    After the observation in 1983 of a leukaemia cluster among children living near the Sellafield nuclear waste reprocessing plant (United Kingdom), numerous epidemiologic studies have been conducted on the risk of cancer or leukaemia in populations in the vicinity of nuclear installations. The methodology of these cohort and case-control studies of mortality or of incidence is reviewed. Some cohort studies have shown an excess of childhood leukaemia, but only in the UK; French, US, Canadian and German studies were negative. In 1990, a first case-control study found a relationship between the risk of leukaemia in children living around Sellafield and the professional exposure of their father to ionizing radiation before conception, but all further studies were negative. A viral infection, facilitated by large influxes of people into isolated areas, has also been suggested as a possible cause of the excess leukaemias. (authors). 26 refs., 3 tabs.

    We investigated the prevalence of juvenile weapon carrying and psychosocial and personality-related risk factors for carrying different types of weapons in a nationally representative, population-based sample of Finnish adolescents. Specifically, we aimed to investigate psychopathic-like personality features as a risk factor for weapon carrying. The participants were 15-16-year-old adolescents from the Finnish self-report delinquency study (n = 4855). Four different groups were formed based on self-reported weapon carrying: no weapon carrying, carrying knife, gun or other weapon. The associations between psychosocial factors, psychopathic-like features and weapon carrying were examined with multinomial logistic regression analysis. 9% of the participants had carried a weapon in the past 12 months. Adolescents with a history of delinquency, victimization and antisocial friends were more likely to carry weapons in general; however, delinquency and victimization were most strongly related to gun carrying, while perceived peer delinquency (antisocial friends) was most strongly related to carrying a knife. Better academic performance was associated with a reduced likelihood of carrying a gun and knife, while feeling secure correlated with a reduced likelihood of gun carrying only. Psychopathic-like features were related to a higher likelihood of weapon carrying, even after adjusting for other risk factors. The findings of the study suggest that adolescents carrying a weapon have a large cluster of problems in their lives, which may vary based on the type of weapon carried. Furthermore, psychopathic-like features strongly relate to a higher risk of carrying a weapon. PMID:25986501

A self-administered structured questionnaire about socio-demographic characteristics, occurrence of headache and its characteristics was employed. Headaches were classified according to the International Headache Society criteria. The chi-square test was used to verify possible associations, being significant p<0.05.RESULTS: After the exclusion of 24 questionnaires that did not met the inclusion criteria, 204 questionnaires were analyzed. The mean age of the adolescents was 14.0±1.4 years. The prevalence of headache was 87.7%. Of the adolescents with headache, 0.5% presented migraine without pure menstrual aura; 6.7%, migraine without aura related to menstruation; 1.6%, non-menstrual migraine without aura; 11.7%, tension-type headache and 79.3%, other headaches. Significant associations were found between pain intensity and the following variables: absenteeism (p=0.001; interference in ADL (p<0.001; medication use (p<0.001; age (p=0.045 and seek for medical care (p<0.022.CONCLUSIONS: The prevalence of headache in female adolescents observed in this study was high, with a negative impact in ADL and school attendance.

    Full Text Available The influence of family relationships on adolescents' behavior and development has been widely investigated. This study examines the relationship between family structure and a adolescents' quality of experience in daily activities and social contexts b adolescents' perceived life influences, challenges and goals. To achieve this aim, Flow Questionnaire and Life Theme Questionnaire were administered to 50 Italian girls (15-21 years of age, 25 living in two-parent families, 25 entrusted to Institutions for Custody of Minors. The findings suggest tha adolescents' perception of a positive and supportive family enviroment fosters the active search for challenges and enjoyment in daily activities, and the involvement in productive and social contexts. On the contrary , negative family perception is related to lack of engagement and motivation, and to the prevalence of low-challenge activities as sources of enjoyment and satisfaction. Although the sample size does not allow us to draw conclusions about causality, the results confirm the crucial role of family in influencing adolescents' psychological and behavioral development.

    Full Text Available Abstract Background Cyberbullying, threatening or harassing another via the internet or mobile phones, does not cause physically harm and thus the consequences are less visible. Little research has been performed on the occurrence of cyberbullying among adolescents or the perception of its seriousness. Only a few population-based studies have been published, none of which included research on the witnessing of cyberbullying. Here, we examined exposure to cyberbullying during the last year, and its frequency and perceived seriousness among 12 to 18-year-old adolescents in Finland. We studied four dimensions of cyberbullying: being a victim, bully, or both victim and bully of cyberbullying, and witnessing the cyberbullying of friends. Methods Self-administered questionnaires, including four questions on cyberbullying, were mailed to a representative sample of 12-, 14-, 16-, and 18-year-old Finns in 2009 (the Adolescent Health and Lifestyle Survey. The respondents could answer via the internet or paper questionnaire. Results The number of respondents was 5516 and the response rate was 56%. Girls more often than boys reported experiencing at least one dimension of cyberbullying during the last year. The proportion was highest among 14-year-olds and lowest among 18-year-olds of both sexes. Among girls, the most commonly encountered dimension was witnessing the cyberbullying of friends (16%; and being a victim was slightly more common than being a bully (11% vs. 9%. Among boys, an equal proportion, approximately 10%, had been a victim, a bully, or had witnessed cyberbullying. The proportion of bully-victims was 4%. Serious and disruptive cyberbullying was experienced by 2% of respondents and weekly cyberbullying by 1%; only 0.5% of respondents had been bullied weekly and considered bullying serious and disruptive. Conclusions Adolescents are commonly exposed to cyberbullying, but it is rarely frequent or considered serious or disruptive. Cyberbullying

A sample of 2,000 adolescents living in tornado-affected communities was assessed via structured telephone interview and invited to a Web-based treatment. The modular treatment addressed symptoms of posttraumatic stress disorder, depression, and alcohol and tobacco use. Participants were randomized to experimental or control conditions after accessing the site. Overall access for the intervention was 35.8%. Module completion for those who accessed ranged from 52.8% to 85.6%. Adolescents with parents who used the Internet to obtain health-related information were more likely to access the treatment. Adolescent males were less likely to access the treatment. Future work is needed to identify strategies to further increase the reach of Web-based treatments to provide clinical services in a postdisaster context. PMID:25622071

    The objective of the study was to determine the similarities and differences between adolescents with psychoactive substances use experience living in urban and rural areas as regards the intensity of Internet addiction symptoms as well as the evaluation of prevalence of psychoactive substances use among adolescents depending on the place of residence. The examined group consisted of 1 860 people (1 320 girls and 540 boys) their average age being 17 years. In the study the following research methods were used: the Sociodemographic Questionnaire designed by the authors, the Internet Addiction Questionnaire by Potembska, the Internet Addiction test by Young, the Internet Addiction Questionnaire (KBUI) designed by Pawłowska and Potembska. Statistically significant differences were found as regards the prevalence of psychoactive substances use by the adolescents living in urban and rural areas and as regards the intensity of Internet addiction symptoms in adolescents, both from the urban and rural areas, who use and do not use illegal drugs. Significantly more adolescents living in urban areas as compared to their peers living in rural areas use psychoactive substances, mainly marihuana. The adolescents who use psychoactive substances, as compared to the adolescents with no experience using illegal drugs, living both in urban and rural areas significantly more often play online violent games and use web pornography. The adolescents living in rural areas who use psychoactive substances significantly more often as compared to the adolescents who do not use these substances claim that it is only thanks to the interactions established on the Internet that they can get acceptance, understanding and appreciation.

    Full Text Available Abstract Background In adult research, neighborhood walkability has been acknowledged as an important construct among the built environmental correlates of physical activity. Research into this association has only recently been extended to adolescents and the current empirical evidence is not consistent. This study investigated whether neighborhood walkability and neighborhood socioeconomic status (SES are associated with physical activity among Belgian adolescents and whether the association between neighborhood walkability and physical activity is moderated by neighborhood SES and gender. Methods In Ghent (Belgium, 32 neighborhoods were selected based on GIS-based walkability and SES derived from census data. In total, 637 adolescents (aged 13-15 year, 49.6% male participated in the study. Physical activity was assessed using accelerometers and the Flemish Physical Activity Questionnaire. To analyze the associations between neighborhood walkability, neighborhood SES and individual physical activity, multivariate multi-level regression analyses were conducted. Results Only in low-SES neighborhoods, neighborhood walkability was positively associated with accelerometer-based moderate to vigorous physical activity and the average activity level expressed in counts/minute. For active transport to and from school, cycling for transport during leisure time and sport during leisure time no association with neighborhood walkability nor, with neighborhood SES was found. For walking for transport during leisure time a negative association with neighborhood SES was found. Gender did not moderate the associations of neighborhood walkability and SES with adolescent physical activity. Conclusions Neighborhood walkability was related to accelerometer-based physical activity only among adolescent boys and girls living in low-SES neighborhoods. The relation of built environment to adolescent physical activity may depend on the context.

    Full Text Available Objectives: This study compares the adherence of immigrant and Spanish adolescents residing in the Madrid region (Spain to national dietary recommendations. The factors compared were the consumption of items from the eight basic food groups (vegetables, fruits, bread/cereals, meat, eggs, fish, legumes and milk/dairy products, including the excessive or deficient consumption of eggs, meat and fish. In addition, the evaluation of excessive sweet foods or soft drinks in the diet was also considered. Subsequently, the influence of length of residence on dietary habits was examined. Materials and methods: Self-reported data were collected in a cross-sectional survey conducted over the period November 2007 to February 2008. The study participants were a representative sample of adolescents aged 13 to 17 years (n = 2,081, 1,055 girls living in the Madrid region. Participants were recruited from secondary schools (grades 7th to 10th randomly selected according to the geographic distribution of adolescents in the region. Results: Immigrant adolescents showed a greater likelihood of not fulfilling recommendations for the consumption of meat, fish, eggs, legumes, bread/cereals, and milk/dairy products. Their diets were also more likely to lack sufficient fish and they also consumed more eggs and more sweet foods and soft drinks than their native counterparts. Spanish adolescents were more likely not to meet recommendations for the intake of vegetables. Length of residence weakly affected dietary habits, with both negative and positive effects observed. Conclusion: The likelihood of not fulfilling dietary recommendations was higher among the immigrant adolescents with the exception of the intake of fruits and vegetables.

    This study explored post-migration experiences of recently migrated Pakistani Muslim adolescent females residing in the United States. In-depth, semi-structured interviews were conducted with thirty Pakistani Muslim adolescent females between the ages of 15 and 18 years living with their families in Houston, Texas. Data obtained from the interviews were evaluated using discourse analysis to identify major reoccurring themes. Participants discussed factors associated with the process of adaptation to the American culture. The results revealed that the main factors associated with adaptation process included positive motivation for migration, family bonding, social support networks, inter-familial communication, aspiration of adolescents to learn other cultures, availability of English-as-second-language programs, participation in community rebuilding activities, and faith practices, English proficiency, peer pressure, and inter-generational conflicts. This study provided much needed information on factors associated with adaptation process of Pakistani Muslim adolescent females in the United States. The results have important implications for improving the adaptation process of this group and offer potential directions for intervention and counseling services. PMID:22940911

    Background : Saudi Arabia has passed through lifestyle changes toward unhealthy dietary patterns such as high fast food consumption. Adolescents and young adults, particularly girls, are the main groups exposed to and affected by these adverse eating behaviors. Objective : The aim of this study was to examine the trends of fast food consumption among adolescent and young adult Saudi girls living in Riyadh, and to compare between them. Design : In a cross-sectional survey, 127 adolescent Saudi girls (13-18 years) and 69 young adult Saudi girls (19-29 years) were randomly recruited to participate in this study. Weight, height, waist circumference, and hip circumference were measured using standardized methods. Twenty-four-hour diet recall and a face-to-face interview food questionnaire were performed. Results : Most of the participants had adequate intake of protein, riboflavin, iron, and sodium, but exhibited low intake for several other nutrients. Among study participants, 95.4% consume restaurants' fast food and 79.1% eat fast food at least once weekly. Burgers and carbonated soft drinks were the main kinds of fast food meals and beverages usually eaten by girls. Adolescent girls who usually ate large portion sizes of fast food had significantly higher mean waist circumference and hip circumference. Participants eat fast food primarily for enjoying the delicious taste, followed by convenience. Restaurants' hygiene and safety standards were the main concern regarding fast food for 62.2% of girls. Finally, international restaurants were preferable by participants to buy fast food compared with local restaurants (70.9% vs. 29.1%). Conclusion : Our findings provide evidence on the high prevalence of fast food consumption among Saudi girls, suggesting an urgent need for community-based nutrition interventions that consider the trends of fast food consumption and targeted eating behaviors of adolescent and young adult girls.

    The purpose of this study was to investigate the relationship between parental efficacy and a new concept entitled parental monitoring efficacy, and to examine the association between parental monitoring efficacy and monitoring. We conducted two studies on two samples of Asian-Indian parents and adolescents living in Chennai, India. In the first study of 241 parents of adolescents in grades, 9-12, we constructed a new measure of parental efficacy that included two factors. The first factor, responding competently to negative adolescent behavior was more strongly predictive of parental monitoring efficacy than the second factor, instilling positive behavior. In the second study of 215 parents and adolescents in grades 10 and 12, parental monitoring efficacy predicted monitoring, especially adolescent disclosure and parental control. The importance of parental control as a monitoring technique among traditional Indian parents was discussed. PMID:25448831

    Population aging creates both a problem (higher taxes on a small group of workers to finance higher public pension and health care costs) and automatic adjustments that help to address that problem. The prospect of longer retirement involves an increased incentive to invest in physical capital, and labour scarcity leads to higher pre-tax wages and an increased incentive to invest in human capital. Thus, productivity growth can be favourably affected by aging. The likely empirical magnitude of...

    International Nuclear Information System (INIS)

    Eightly citizens of the former Soviet Union were examined after immigrating to the U.S. from 1989-91. During the Chernobyl nuclear reactor accident, they were residents of four cities (Kiev, Gomel, Bobrujsk and Mozyr) all located 100-200 km from the plant. Examination of each individual included one - four whole-body radiation counts and a cytogenetic analysis of mitogen-stimulated peripheral blood lymphocytes for micronuclei as a biomarker of chromosome damage. In addition, 19 of the subjects heterozygous for the MN blood group were further tested using the glycophorin-A (GPA) specific locus mutation assay on erythrocytes. Results showed 48 immigrants including persons from all four cities had detectable levels of radiocesium contamination. The highest body burdens were found in a family who had lived in Mozyr, about 100 km northwest of Chernobyl. The observed decline in radiocesium of these subjects was consistent with the published biological half-life of 137Cs. Adults showed the highest body burdens of radiocesium and the adult males from all four cities consistently showed higher levels than adult females. Age was found to account for much of the variation of lymphocyte micronuclei, however, a significant correlation was also demonstrated with radiocesium body burden and the absorbed dose for 20 subjects. Consistent with earlier studies, the frequency of simple allele loss (N/O) variants at the autosomal GPA locus was significantly higher than age- and sex-matched contemporaneous controls. Nine of the 19 MN heterozygotes showed variant frequencies 4-fold higher than mean frequency of matched controls. The allele loss mutations also showed a significant positive correlation with the radiocesium body burden. Results from this study indicate individuals living as far as 100-200 km from Chernobyl received radiation exposure from fallout sufficient to induce both cytogenetic abnormalities and specific locus mutations in hematopoietic tissues

    In 1951 the Indian population arrived at the end of its period of slow growth associated with British colonial rule. The mortality rate was still high at 27-31/1000; with a birth rate of 41-43/1000, the annual rate of growth was 1.2-1.3%. In the following decade, mortality declined appreciably due to progress in medicine and public health, but after 1961 the mortality decline slowed. Fertility began to decline, but much more slowly than hoped. The rate of urbanization was more moderate than in many developing countries, and the sex ratio for reasons not well understood continued to favor males. The rate of increase in several states slowed between 1961-71, and it appeared plausible that declining natality was a factor. The proportion literate increased from 24.03% in 1961 to 36.17% in 1981. In 1981, 46.74% of men and 24.88% of women were literate. Between 1951-81, mortality declined from 27-31/1000 to 13/1000 while fertility declined from 41-43/1000 to 34/1000. The effects of the future fertility decline will be partially offset by declining mortality. Although India has had some kind of family planning program since the 5-Year Plan of 1951-56, progress has been slow and uneven. Concern about overpopulation is increasing among the population, but available methods of contraception are imperfect, many programs are poorly administered, and skilled personnel are in short supply. The age at marriage has increased somewhat but not enough to have a major impact on fertility. Despite the extreme difficulty of establishing the caloric intake and real incomes of the poorest classes, it is known that wide disparities of income existed before independence and that population growth began to outpace increases in agricultural production long ago in some regions. However, after independence food production in the country as a whole increased by 114.3% while population increased by 93.7%. Growth of agricultural productivity has subsequently slowed. Improvements have been unevenly

    Studies from sub-Saharan Africa indicate that children made vulnerable by poverty have been disproportionately affected by HIV with many exposed via mother-to-child transmission. For youth living with HIV, adherence to life saving treatment regimens are likely to be affected by the complex set of economic and social circumstances that challenge their families and also exacerbate health problems. Using baseline data from the National Institute of Child and Human Development (NICHD) funded Suubi+Adherence study, we examined the extent to which individual and composite measures of equity predict self-reported adherence among Ugandan adolescents aged 10–16 (n = 702) living with HIV. Results showed that greater asset ownership, specifically familial possession of seven or more tangible assets, was associated with greater odds of self-reported adherence (OR 1.69, 95% CI: 1.00–2.85). Our analyses also indicated that distance to the nearest health clinic impacts youth’s adherence to an ARV regimen. Youth who reported living nearest to a clinic were significantly more likely to report optimal adherence (OR 1.49, 95% CI: 0.92–2.40). Moreover, applying the composite equity scores, we found that adolescents with greater economic advantage in ownership of household assets, financial savings, and caregiver employment had higher odds of adherence by a factor of 1.70 (95% CI: 1.07–2.70). These findings suggest that interventions addressing economic and social inequities may be beneficial to increase ART uptake among economically vulnerable youth, especially in sub-Saharan Africa. This is one of the first studies to address the question of equity in adherence to antiretroviral therapy among economically vulnerable youth with HIV. PMID:27392003

Further factors considered were country of birth, LOR and several biological, sociodemographic, lifestyle and health-related variables. Results: According to the three logistic regression models constructed, female immigrant adolescents on the whole showed a greater ED risk (OR = 1.95; 95%CI 1.292.95; p = 0.001 than native adolescents. Moreover, the likelihood of ED was higher among female immigrants living in Spain for <6 years than for Spanish native females (OR = 2.44; 95%CI 1.42-4.18; p = 0.001, while no significant differences were found when female natives were compared with female immigrants living in this country for ≥ 6 years. Similarly, no differences were observed in the ED risk recorded for male native and immigrant adolescents, both as a whole and by length of residence in Spain. Conclusions: The immigrant status and the length of Spanish residence are relevant factors in regard to the ED risk in adolescents living in Madrid.

    Full Text Available Adolescence is a developmental period that implies a series of rapid changes that might complicate the role of parents. This study evaluates changes in parental monitoring and the strategies to solve family conflicts reported by parents who participated in the "Living Adolescence in Family" program in local social services and school centers. In addition, the study analyses the moderating role of family and facilitator variables that may affect the final results. The participants were 697 parents attending the social services (438 in the intervention group and 259 in the control group and 1283 parents from school centers (880 in the intervention group and 403 in the control group. The results showed that families from local social services decreased the amount of control and improved monitoring in education and leisure spheres as well as self-disclosure whereas the families coming from school centers improved supervision in leisure and in self-disclosure. In addition, both groups of families improved their strategies for solving family conflicts, increasing the use of integrative strategies and decreasing the use of dominant strategies. There were differences across contexts: the results of the program in the social services context differed according to the participant and professional profiles whereas program results were more homogeneous in the school context. In sum, the program appears to be an efficient work tool, both for the professionals who work with at-risk families with adolescents and for the teachers who make use of the program for families with children at risk of early school dropout.

    2013-12-01

    March of the Living (MOTL) is a worldwide two-week trip for high school seniors to learn about the Holocaust by traveling to sites of concentration/death camps and Jewish historical sites in Poland and Israel. The mission statement of MOTL International states that participants will be able to "bolster their Jewish identity by acquainting them with the rich Jewish heritage in pre-war Eastern Europe." However, this claim has never been studied quantitatively. Therefore, 152 adolescents who participated in MOTL voluntarily completed an initial background questionnaire, a Jewish Identity Survey and a Global Domains Survey pre-MOTL, end-Poland and end-Israel. Results suggest that Jewish identity did not substantially increase overall or from one time period to the next. PMID:23801019

    Full Text Available Abstract Background Identification of non-modifiable correlates of physical activity and sedentary behaviour in youth contributes to the development of effective targeted intervention strategies. The purpose of this research was to examine the relationships between family circumstances (e.g. socio-economic status, single vs. dual parent household, presence/absence of siblings and leisure-time physical activity and sedentary behaviours in adolescents. Methods A total of 1171 adolescents (40% male; mean age 14.8 years completed ecological momentary assessment diaries every 15 minutes for 3 weekdays outside of school hours and 1 weekend day. Analysed behaviours were sports/exercise, active travel, TV viewing, computer use, sedentary socialising (hanging-out, using the telephone, sitting and talking and total sedentary behaviour. Linear regression was employed to estimate levels of association between individual family circumstance variables and each behaviour. Results Compared to girls from higher socioeconomic status (SES groups, girls from low SES groups reported higher weekend TV viewing and higher weekday total sedentary behaviour. For boys, single parent status was associated with greater total sedentary behaviour compared to those from dual parent households. Boys and girls from low socio-economic neighbourhoods reported lower participation in sports/exercise compared to those living in higher socio-economic neighbourhoods. Conclusion Associations were not consistent across behaviours or between genders. Overall, findings indicate that boys from single parent households and girls from low socio-economic families may be at increased risk of high sedentary behaviour. Those living in low socioeconomic neighbourhoods may be at increased risk of reduced participation in sports and exercise.

    2012-01-01

    Problematic use of the mobile telephone is an emerging phenomenon in our society, and one which particularly affects the teenage population. Knowledge from research on the problematic use of this technology is necessary, since such use can give rise to a behavioural pattern with addictive characteristics. There are hardly any scales for measuring possible problematic use of mobile phones, and none at all adapted exclusively for the Spanish adolescent population. The scale most widely used internationally is the Mobile Phone Problem Use Scale (MPPUS). The aim of the present study is to adapt the MPPUS for use with Spanish adolescents. The Spanish version of the questionnaire was administered to a sample of 1132 adolescents aged 12 to 18. Reliability and factorial validity were comparable to those obtained in adult population, so that the measure of problematic mobile phone use in Spanish teenagers is one-dimensional. A prevalence of 14.8% of problematic users was detected. PMID:22648315

    Full Text Available Abstract Background Previous research has shown that between 80 and 90 percent of adult smokers report having started smoking before 18 years of age. Several studies have revealed that multiple social factors influence the likelihood of smoking during adolescence, the period during which the onset of smoking usually occurs. To better understand the social mechanisms that influence adolescent smoking, we analyzed the relationship and relative importance of a broad spectrum of social variables in adolescent smoking in Iceland, a Nordic country with high per-capita income. Methods We used cross-sectional data from 7,430 14- to 16 year-old students (approximately 81% of all Icelanders in these age cohorts in the 2006 Youth in Iceland study. The Youth in Iceland studies are designed to investigate the role of several cognitive, behavioral, and social factors in the lives of adolescents, and the data collected are used to inform the design, implementation, and evaluation of substance use prevention programs that are being developed by Icelandic social scientists, policy makers, and practitioners. Results Our analysis revealed that friends' smoking behavior and attitude toward smoking were strongly associated with adolescent smoking and other tobacco use, as well as alcohol consumption during the previous 30 days. Main protective factors were parent's perceived attitude toward smoking, the quantity of time spent with parents, absence of serious verbal conflict between parents and adolescents, and participation in physical activity. Family structure was related to adolescent smoking to a small extent, but other background factors were not. Conclusion We conclude that multiple social factors are related to adolescent smoking. Parents and other primary preventive agents need to be informed about the complicated nature of the adolescent social world in order to maximize their impact.

    Sleep problems in children and adolescents are a significant public health concern and may be linked to a variety of psychoemotional difficulties. This study aimed to evaluate sleep quality and associated factors in conflict-affected Georgian adolescents after 9 months of forced displacement. Thirty-three internally displaced adolescents (mean age 11.4 years) and 33 adolescents (mean age 10.8 years) from the general population completed the Epworth Sleepiness Scale and the Children's Depression Inventory (CDI). Parents completed the Children's Sleep-Wake Scale and provided information on their socioeconomic status (SES) and the adolescents' sleep behavior, academic performance, and peer social relationships. The groups differed significantly in sleep quality, peer relationships, SES, and CDI scores. In the internally displaced group, the only significant predictor of sleep quality was SES, which increased the predictive capacity of the model (demographic and psychosocial variables) by 20% in the hierarchical analyses. The most significant predictor in the non-internally displaced group was CDI. This research indicates that displacement may affect sleep quality and psychosocial functioning. The importance of family SES as a contributing factor to displaced adolescents' poor sleep quality is highlighted. An integrated approach designed to improve the psychosocial environment of internally displaced adolescents is needed for their protection. PMID:26311481

    2012-12-01

    While vampires haunt contemporary American pop culture, the undead have populated psychoanalytic literature from Abraham's March 15, 1915 letter to Freud to today. PEP lists 439 psychoanalytic references to the undead (99 on zombies; 288 on vampires; 52 on werewolves). A selection of papers are cited, focusing on clinical cases, ethnography media and literature, even breast-feeding fantasized as blood sucking, associated with primitive dynamics. Previous works' libidinal, object relations, and dynamic perspectives on various "undeads" are summarized. This paper's contribution to the psychoanalytic literature is to examine the relationship of the three categories of undead both among each other and in their relation to the living. This paper presents a young adolescent's extensive play and fantasies about the undead, and his sophisticated intrapsychic model for the undead, developed prior to treatment, that kept him in psychical equilibrium, yet also kept him from feeling alive. This model has developmental implications for handling three types of transferences. Also, we may shed light on both contemporary preoccupation with the undead in contemporary American popular culture, and its endurance over time in Western culture. PMID:23253062

  9. Impulsivity in the prediction of suicidal behavior in adolescent populations.

    Science.gov (United States)

    Gorlyn, Marianne

    2005-01-01

    Impulsivity has been identified as a key factor in risk of suicidal behavior in adolescent and adult patients. However, a lack of consensus about the definition of impulsivity has led to difficulty in its measurement. Impulsivity self-report scales exhibit low intercorrelations, are subject to response bias, and incorporate multiple subfactors. Performance tests may be less sensitive to response biases, as well as be more precise measures of dimensions of impulsivity, but each test alone does not provide a comprehensive measure of the trait. Assessing impulsivity in child and adolescent groups presents additional methodological problems, such as an overlap between limited impulse control due to developmental factors and psychopathology. A multiple measures approach to assessing impulsivity is suggested. PMID:16231471

    Full Text Available Objective: The present study is aimed to identify the most important long-term stressors for Romanian adolescents. Material and Methods: 1143 randomly selected Romanian subjects were considered. Mean age in the study sample was 15.02, with a standard deviation (SD of 0.371. About 65.4% of subjects were females. Daily hassles related to the family environment, physical state, psychological status, financial status of the family and interpersonal relationships were covered Results: 22.7% of the subjects reported daily hassles related to their familial environment, 7.8% reported daily hassles related to their physical state, 59.6% reported daily hassles related to their psychological state, 41.9% reported financial difficulties of their families and 4.4% of adolescent reported being bullied. Conclusion: Stressors that appear to be most relevant for adolescents in north-western Romania are: financial difficulties of the family and psychological difficulties. There are no differences in reporting bullying between genders and that this phenomenon is less frequent in Romania. A greater attention should be paid to the effects of workforce migration.

    Pulkki-Råback Laura

    2012-03-01

    Full Text Available Abstract Background An increasing proportion of the population lives in one-person households. The authors examined whether living alone predicts the use of antidepressant medication and whether socioeconomic, psychosocial, or behavioral factors explain this association. Methods The participants were a nationally representative sample of working-age Finns from the Health 2000 Study, totaling 1695 men and 1776 women with a mean age of 44.6 years. In the baseline survey in 2000, living arrangements (living alone vs. not and potential explanatory factors, including psychosocial factors (social support, work climate, hostility, sociodemographic factors (occupational grade, education, income, unemployment, urbanicity, rental living, housing conditions, and health behaviors (smoking, alcohol use, physical activity, obesity, were measured. Antidepressant medication use was followed up from 2000 to 2008 through linkage to national prescription registers. Results Participants living alone had a 1.81-fold (CI = 1.46-2.23 higher purchase rate of antidepressants during the follow-up period than those who did not live alone. Adjustment for sociodemographic factors attenuated this association by 21% (adjusted OR = 1.64, CI = 1.32-2.05. The corresponding attenuation was 12% after adjustment for psychosocial factors (adjusted OR = 1.71, CI = 1.38-2.11 and 9% after adjustment for health behaviors (adjusted OR = 1.74, CI = 1.41-2.14. Gender-stratified analyses showed that in women the greatest attenuation was related to sociodemographic factors and in men to psychosocial factors. Conclusions These data suggest that people living alone may be at increased risk of developing mental health problems. The public health value is in recognizing that people who live alone are more likely to have material and psychosocial problems that may contribute to excess mental health problems in this population group.

    Adolescents living with HIV (ALHIV) face many psychosocial challenges, including HIV disclosure to others. Given the importance of socialization during the adolescent transition process, this study investigated the psychological and social factors influencing self-disclosure of own HIV status to peers. We examined social HIV self-disclosure to peers, and its relationship to perceived HIV-related stigma, self-efficacy to disclose, self-esteem, and social support among a sample of n = 582 ALHIV aged 13–17 years in Kampala, Uganda, and Western Kenya. Data were collected between February and April 2011. Among them, 39% were double orphans. We conducted a secondary data analysis to assess the degree of social disclosure, reactions received, and influencing factors. Interviewer-administered questionnaires assessed medical, socio-demographic, and psychological variables (Rosenberg self-esteem scale; self-efficacy to disclose to peers), HIV-related stigma (10-item stigma scale), and social support (family–life and friends). Descriptive, bivariate, and logistic regression analyses were performed with social self-disclosure to peers with gender as covariates. Almost half of ALHIV had told nobody (except health-care providers) about their HIV status, and about 18% had disclosed to either one of their friends, schoolmates, or a boy- or girlfriend. Logistic regression models revealed that having disclosed to peers was significantly related to being older, being a paternal orphan, contributing to family income, regular visits to the HIV clinic, and greater social support through peers. Low self-efficacy to disclose was negatively associated to the outcome variable. While social self-disclosure was linked to individual factors such as self-efficacy, factors relating to the social context and adolescents’ access to psychosocial resources play an important role. ALHIV need safe environments to practice disclosure skills. Interventions should enable them to make optimal use of

    2012-12-01

    Full Text Available Abstract Background Adolescent girls are an overlooked group within conflict-affected populations and their sexual health needs are often neglected. Girls are disproportionately at risk of HIV and other STIs in times of conflict, however the lack of recognition of their unique sexual health needs has resulted in a dearth of distinctive HIV protection and prevention responses. Departing from the recognition of a paucity of literature on the distinct vulnerabilities of girls in time of conflict, this study sought to deepen the knowledge base on this issue by qualitatively exploring the sexual vulnerabilities of adolescent girls surviving abduction and displacement in Northern Uganda. Methods Over a ten-month period between 2004–2005, at the height of the Lord’s Resistance Army insurgency in Northern Uganda, 116 in-depth interviews and 16 focus group discussions were held with adolescent girls and adult women living in three displacement camps in Gulu district, Northern Uganda. The data was transcribed and key themes and common issues were identified. Once all data was coded the ethnographic software programme ATLAS was used to compare and contrast themes and categories generated in the in-depth interviews and focus group discussions. Results Our results demonstrated the erosion of traditional Acholi mentoring and belief systems that had previously served to protect adolescent girls’ sexuality. This disintegration combined with: the collapse of livelihoods; being left in camps unsupervised and idle during the day; commuting within camp perimeters at night away from the family hut to sleep in more central locations due to privacy and insecurity issues, and; inadequate access to appropriate sexual health information and services, all contribute to adolescent girls’ heightened sexual vulnerability and subsequent enhanced risk for HIV/AIDS in times of conflict. Conclusions Conflict prevention planners, resettlement programme developers, and

The aim of this research was to evaluated eating and physical activity behaviours and habits, nutritional and food knowledge, beliefs and self-efficacy related to diet and health of the adolescents of the city of Belgrade, Serbia. Methods. A dietary questionnaire previously constructed and tested in adolescent population from Italy was self-administrated. We evaluated eating habits, physical activity, meaning of healthy and unhealthy dietary habits and food, self-efficacy, barriers affecting food choices, nutritional and food safety, and body mass index (BMI of the adolescents. The sample included 707 adolescents, the mean age of 15,8 ± 2 years enrolled in the first grade at several high schools in Belgrade. Results. Only 27% of the adolescents had satisfactory eating habits; 31% have a very active lifestyle; 7% good nutritional knowledge and 6- 12% satisfactory food safety knowledge and hygiene practices. Conclusion. Significant deviations from recommendations for healthy lifestyle was noted in adolescents’ habits, knowledge and practice. It is therefore necessary to develop and organize programs for promotion of healthy behaviours adapted to the adolescents’ needs. [Projekat Ministarstva nauke Republike Srbije, br. III47015

Religiosity is one way for adolescents to deal with challenges in life thereby avoiding immoral activities. This is because religiosity may help to balance adolescent emotional, cognitive and social developments.The purpose of this study is t...

    Full Text Available Quantitative study aimed to know the understanding of adolescents about their sexuality and how the exercises for further intervention by the health team. We administered a structured questionnaire in a sample of 43 adolescents aged 12 to 19 years living in the area covered by the Family Health Unit Dr. Fabio I and II. The data were tabulated in the spreadsheet program Microsoft Office Excel 2007, allowing for a descriptive treatment, keeping a confidence interval of 95%. The results show that 32.5% of participants had first intercourse between 12 and 16, and 50% of them admit they have used a condom at last intercourse. In addition, 4.6% have had some kind of sexually transmitted disease. The study indicates the need for educational activities in sexual and reproductive health to adolescents facing the neighborhoods studied, with a view to promoting health.

    Cybersuicide is a term used in reference to suicide and its ideations on the Internet. Cybersuicide is associated with websites that lure vulnerable members of society and empower them with various methods and approaches to deliberate self-harm. Ease of accessibility to the Internet and the rate at which information is dispersed contribute to the promotion of 'offing' one's self which is particularly appealing to adolescents. This study aims to explore this phenomenon, which seems to be spreading across generations, cultures, and races. Information and articles regarding Internet suicide and other terminology, as well as sub-classifications concerning this new form of suicide, were reviewed. Through search engines such as Google, Yahoo and Wikipedia, we investigated the differentiations between 'web cam' suicide, 'net suicide packs', sites that merely offer advice on how to commit suicide and sites that are essential in providing the means of performing the act. Additionally, materials published in scientific journals and data published by the Public Health Services, Centers for Disease Control, and materials from private media agencies were reviewed. Resources were also sourced from The Faculty of Medical Sciences Library, UWI at Mt. Hope. Cybersuicide is a worldwide problem among adolescents and a challenge of the future. PMID:19702194

    OBJECTIVE To identify the factors associated with severity of malocclusion in a population of adolescents. METHODS In this cross-sectional population-based study, the sample size (n = 761) was calculated considering a prevalence of malocclusion of 50.0%, with a 95% confidence level and a 5.0% precision level. The study adopted correction for the effect of delineation (deff = 2), and a 20.0% increase to offset losses and refusals. Multistage probability cluster sampling was adopted. Trained and calibrated professionals performed the intraoral examinations and interviews in households. The dependent variable (severity of malocclusion) was assessed using the Dental Aesthetic Index (DAI). The independent variables were grouped into five blocks: demographic characteristics, socioeconomic condition, use of dental services, health-related behavior and oral health subjective conditions. The ordinal logistic regression model was used to identify the factors associated with severity of malocclusion. RESULTS We interviewed and examined 736 adolescents (91.5% response rate), 69.9% of whom showed no abnormalities or slight malocclusion. Defined malocclusion was observed in 17.8% of the adolescents, being severe or very severe in 12.6%, with pressing or essential need of orthodontic treatment. The probabilities of greater severity of malocclusion were higher among adolescents who self-reported as black, indigenous, pardo or yellow, with lower per capita income, having harmful oral habits, negative perception of their appearance and perception of social relationship affected by oral health. CONCLUSIONS Severe or very severe malocclusion was more prevalent among socially disadvantaged adolescents, with reported harmful habits and perception of compromised esthetics and social relationships. Given that malocclusion can interfere with the self-esteem of adolescents, it is essential to improve public policy for the inclusion of orthodontic treatment among health care provided to this

    Adolescents living in the Indian subcontinent form a significant proportion of the general population. India is home to 236 million adolescents, who make up one-fifth of the total population of India. Adolescent health is gradually considered an important issue by the government of India. Awareness is increasing about adolescent needs. Health care professionals in particular are becoming more interested in the specific needs of adolescent age. Adolescent medicine as a subspecialty of pediatrics has also gained importance gradually over the last decade. In a hospital setting, adolescent-specific needs are met, albeit not in a uniform manner in all the health centers. After having been trained in adolescent medicine in India and abroad, I present this paper as a bird's eye view of the practice of adolescent health and medicine in India. PMID:27447203

    The post-renal transplant courses of 53 children and adolescents were evaluated for the prevalence and the etiology of hypertension. The blood pressures were averaged over specific time periods following transplantation and converted to percentile ranks according to standards for age. The number of antihypertensives employed to control blood pressure was assessed. Factors such as sex, obesity, race, donor source, antigen match, steroid administration, rejection, recurrent glomerulonephritis, pre-transplant nephrectomy, renal function and proteinuria were assessed as to their importance in producing hypertension or normotension in the post-transplant period. The average blood pressure was well within acceptable range shortly after transplantation. The patients requiring antihypertensives to control blood pressure dropped by two years post transplant. Chronic rejection was by far the most important factor influencing average blood pressure and the need to employ antihypertensives. Alternate-day prednisone and good graft function were important in establishing the normotensive state. PMID:7042620

    2010-04-01

    Full Text Available This study assessed and compared the daily step counts recorded by two different motion sensors in order to estimate the free-living physical activity of 135 adolescent girls. Each girl concurrently wore a Yamax pedometer and an ActiGraph accelerometer (criterion measure every day for seven consecutive days. The convergent validity of the pedometer can be considered intermediate when used to measure the step counts in free-living physical activity; but should be considered with caution when used to classify participants’ step counts into corresponding physical activity categories because of a likelihood of ‘erroneous’ classification in comparison with the accelerometer.

    Full Text Available Background and Objectives: Obsessive symptoms among children and adolescent age groups are increasing, an observation made by mental health professionals working with this age group. Our epidemiological study targeted secondary school students to estimate the prevalence of obsessive symptoms, obsessive compulsive disorder and their different obsessive compulsive contents. Methods: The study is cross sectional carried on 1299 secondary school students, the sample size was chosen based on an estimated Obsessive Compulsive Disorder (OCD prevalence of 2% in literature. Equal samples were recruited from the 3 educative zones in Alexandria Governorate. Obsessive compulsive symptoms were assessed by the Arabic version of Lyeton obsessive inventory child version LOI-CV. Students scoring above 35 were subjected to the Mini International Neuropsychiatric Interview for children MINI-KID Arabic. OCD patient students detected by MINI-KID were assessed by psychiatric interview to confirm fulfilling criteria of OCD according to DSM IV-TR criteria. Different obsessive compulsive symptoms were assessed by a standardized questionnaire. Results: Among the studied sample (n = 1299, 201 students scored > 35 on LOI-CV i.e. 15.5% of the total sample have OCS. The prevalence of OCD among studied sample was 2.2% as 29 students from the OCS students were fulfilling diagnostic criteria for OCD according to DSM-IV TR. Common obsessive symptoms were of excessive conscience 65.5%, blasphemous 55.2%, repeated words 51.7% and sexual obsessions 48.2%. Conclusions: The prevalence of obsessive compulsive symptoms is high among adolescent age group. Cultural impact should be considered to better understand obsessive phenomenology, raising the importance of OCD study from a transcultural perspective.

    Philippe R Mutwa

    Full Text Available INTRODUCTION: Adherence to combination antiretroviral therapy (cART is vital for HIV-infected adolescents for survival and quality of life. However, this age group faces many challenges to remain adherent. We used multiple data sources (role-play, focus group discussions (FGD, and in-depth interviews (IDI to better understand adherence barriers for Rwandan adolescents. Forty-two HIV positive adolescents (ages 12-21 and a selection of their primary caregivers were interviewed. All were perinatally-infected and received (cART for ≥ 12 months. Topics discussed during FGDs and IDIs included learning HIV status, disclosure and stigma, care and treatment issues, cART adherence barriers. RESULTS: Median age was 17 years, 45% female, 45% orphaned, and 48% in boarding schools. We identified three overarching but inter-related themes that appeared to influence adherence. Stigma, perceived and experienced, and inadvertent disclosure of HIV status hampered adolescents from obtaining and taking their drugs, attending clinic visits, carrying their cARTs with them in public. The second major theme was the need for better support, in particular for adolescents with different living situations, (orphanages, foster-care, and boarding schools. Lack of privacy to keep and take medication came out as major barrier for adolescents living in congested households, as well the institutionalization of boarding schools where privacy is almost non-existent. The third important theme was the desire to be 'normal' and not be recognized as an HIV-infected individual, and to have a normal life not perturbed by taking a regimen of medications or being forced to disclose where others would treat them differently. CONCLUSIONS: We propose better management of HIV-infected adolescents integrated into boarding school, orphanages, and foster care; training of school-faculty on how to support students and allow them privacy for taking their medications. To provide better care and

    The aim of the current study was to assess the association between sleep duration and sleep patterns and academic performance in 16-19 year-old adolescents using registry-based academic grades. A large population-based study from Norway conducted in 2012, the youth@hordaland-survey, surveyed 7798 adolescents aged 16-19 years (53.5% girls). The survey was linked with objective outcome data on school performance. Self-reported sleep measures provided information on sleep duration, sleep efficiency, sleep deficit and bedtime differences between weekday and weekend. School performance [grade point average (GPA)] was obtained from official administrative registries. Most sleep parameters were associated with increased risk for poor school performance. After adjusting for sociodemographic information, short sleep duration and sleep deficit were the sleep measures with the highest odds of poor GPA (lowest quartile). Weekday bedtime was associated significantly with GPA, with adolescents going to bed between 22:00 and 23:00 hours having the best GPA. Also, delayed sleep schedule during weekends was associated with poor academic performance. The associations were somewhat reduced after additional adjustment for non-attendance at school, but remained significant in the fully adjusted models. In conclusion, the demonstrated relationship between sleep problems and poor academic performance suggests that careful assessment of sleep is warranted when adolescents are underperforming at school. Future studies are needed on the association between impaired sleep in adolescence and later functioning in adulthood. PMID:26825591

    Childhood maltreatment is known to increase the risk of future psychiatric disorders. In the present study, we explored the impact of experienced maltreatment on the prevalence and comorbidity of psychiatric disorders in a high-risk population of adolescents in residential care units. We also studied the impact of poly-victimization. The participants of the study were adolescents in residential care units in Norway (n=335, mean age 16.8 years, girls 58.5%). A diagnostic interview (Child and Adolescent Psychiatric Assessment Interview) was used, yielding information about previous maltreatment (witnessing violence, victim of family violence, community violence, sexual abuse) and DSM-IV diagnoses present in the last three months. Exposure to maltreatment was reported by 71%, and in this group, we found significantly more Asperger's syndrome (AS) (p=.041), conduct disorder (CD) (p=.049), major depressive disorder (MDD) (p=.001), dysthymia (p=.030), general anxiety disorder (GAD) (psuicide (p=.006). We found significantly more comorbid disorders in the maltreated group. Poly-victimization was studied by constructing a scale comprised of witnessing violence, victim of family violence, victim of sexual abuse and household dysfunction. We found that poly-victimization was associated with significantly increased risk of MDD, GAD, AS, CD, and having attempted suicide (padolescent population, and that trauma informed care is essential for adolescents in residential youth care.

    Full Text Available OBJECTIVE: We provide a population-based overview of health behaviours of children and adolescents with type 1 diabetes in comparison to the general population, and analyse their relevance for glycaemic control and self-rated health status. METHODS: Data from questionnaires of 11- to 17-year-old children and adolescents with diabetes (n = 629 were compared to a representative sample (n = 6,813. RESULTS: Children and adolescents with type 1 diabetes had a significantly increased odds of infrequent physical activity (adjusted OR 1.56, short overall duration of physical activity per week (OR 1.55, difference -1.3 hours/week, and high daily computer use (OR 2.51. They had a lower odds of active and passive smoking (OR 0.31 and OR 0.29, and high daily television time (OR 0.68. The odds of an at least good and excellent self-rated health status was increased with intense physical activity, and decreased with active smoking and prolonged daily use of computer and television. Active smoking and prolonged daily use of computer were associated with higher HbA1c. CONCLUSIONS: Children and adolescents with type 1 diabetes showed a different profile of health behaviour. Their overall health may improve if their education stresses specifically frequent physical activity with longer overall duration and less frequent television or computer use.

    Full Text Available The scope of this article is to present and analyze data from Brazilian foster care services for children / adolescents from the perspective of family reintegration. It also seeks to support the implementation of public policies in order to provide effective reintegration in accordance with the differing local contexts. It uses data from 1,157 municipalities that have foster care services. The methodology takes into account the data collection of 2,624 Brazilian centers and 36,929 children and adolescents in care. The growing number of children/adolescents in care is in line with the increase in population size: 8.4 per small city; 60 per large city and 602.4 per metropolis. With respect to care residence in a different municipality there are varying indices: 12.4% in metropolises and 33.6% in small cities, revealing the absence of centers close to family units in the smaller communities. Regarding the activities promoted together with families, it was seen that there are still units that do not perform any activities, which runs contrary to Brazilian law. It is clear that policies for the child/adolescent in foster care centers need to consider the capacity of the municipality in accordance with population size to implement support actions for families to assist in family reintegration.

    Full Text Available Abstract Background We investigated the association between maternal anthropometric measurements in prepregnancy and at the end of pregnancy and their children's systolic (SBP and diastolic (DBP blood pressure at 11 years of age, in a prospective cohort study. Methods All hospital births which took place in 1993 in the city of Pelotas - Brazil, were identified (5,249 live births. In 2004, the overall proportion of follow-up was 85% and we obtained arterial blood pressure measurements of 4,452 adolescents. Results Independent variables analyzed included maternal prepregnancy weight and body mass index (BMI and maternal weight, and height at the end of pregnancy. Multiple linear regression analysis controlling for the following confounders were carried out: adolescent's skin color, family income at birth, smoking, alcohol intake during pregnancy, and gestational arterial hypertension. Mean SBP and DBP were 101.9 mmHg (SD 12.3 and 63.4 mmHg (SD 9.9, respectively. Maternal prepregnancy weight and BMI, and weight at the end of pregnancy were positively associated with both SBP and DBP in adolescent subjects of both sexes; maternal height was positively associated with SBP only among males. Conclusions Adequate evaluation of maternal anthropometric characteristics during pregnancy may prevent high levels of blood pressure among adolescent children.

    Full Text Available Abstract Background Anxious parents have many concerns about the future health of their atopic infants. Paediatricians and primary care practitioners need to seek knowledge on long-term outcomes in order to cope with the increasing caseload of suspected allergy and the concerns of parents. The aim of the study was to assess suspected and diagnosed allergy in infancy as predictors of allergy and asthma in adolescence. Methods Families expecting their first baby and making their first visit to a maternity health care clinic in 1986 were selected as the study population in a random sample. There were 1278 eligible study families. The data were provided of the children at the ages of 9 and 18 months and 3, 5, 12, 15 and 18 years by health care professionals, parents, and adolescents (themselves. Results At the age of 9 months, the prevalence of allergy suspicions was distinctly higher than that of allergy diagnoses. At the age of five years suspected allergy approaches were nil, and the prevalence of diagnosed allergy was about 9%. During the adolescence, the prevalence of self-reported allergy increases steadily up to the age of 18 years, and that of asthma remains at approximately 5%. Suspected allergy at the age of 9 or 18 months and at the 5 years of age does not predict allergy at adolescence. Compared with non-allergic children, children with definite allergy at the age of 5 were over 8 times more likely to have allergy and nearly 7 times more likely to have asthma in adolescence. Conclusion An early ascertained diagnosis of allergy, but not suspicions of allergy, predicts prevailing allergy in adolescence. Efforts need to be focused on accurate diagnosis of early childhood allergies.

    Full Text Available Abstract Background This study investigates the relationship between parental drinking and school adjustment in a total population sample of adolescents, with independent reports from mothers, fathers, and adolescents. As a group, children of alcohol abusers have previously been found to exhibit lowered academic achievement. However, few studies address which parts of school adjustment that may be impaired. Both a genetic approach and social strains predict elevated problem scores in these children. Previous research has had limitations such as only recruiting cases from clinics, relying on single responders for all measures, or incomplete control for comorbid psychopathology. The specific effects of maternal and paternal alcohol use are also understudied. Methods In a Norwegian county, 88% of the population aged 13-19 years participated in a health survey (N = 8984. Among other variables, adolescents reported on four dimensions of school adjustment, while mothers and fathers reported their own drinking behaviour. Mental distress and other control variables were adjusted for. Multivariate analysis including generalized estimation equations was applied to investigate associations. Results Compared to children of light drinkers, children of alcohol abusers had moderately elevated attention and conduct problem scores. Maternal alcohol abuse was particularly predictive of such problems. Children of abstainers did significantly better than children of light drinkers. Controlling for adolescent mental distress reduced the association between maternal abuse and attention problems. The associations between parental reported drinking and school adjustment were further reduced when controlling for the children's report of seeing their parents drunk, which itself predicted school adjustment. Controlling for parental mental distress did not reduce the associations. Conclusions Parental alcohol abuse is an independent risk factor for attention and conduct

    The activity of growing living bacteria was investigated using real-time and in situ rheology -- in stationary and oscillatory shear. Two different strains of the human pathogen Staphylococcus aureus -- strain COL and its isogenic cell wall autolysis mutant -- were considered in this work. For low bacteria density, strain COL forms small clusters, while the mutant, presenting deficient cell separation, forms irregular larger aggregates. In the early stages of growth, when subjected to a stationary shear, the viscosity of both strains increases with the population of cells. As the bacteria reach the exponential phase of growth, the viscosity of the two strains follow different and rich behaviours, with no counterpart in the optical density or in the population's colony forming units measurements. While the viscosity of strain COL keeps increasing during the exponential phase and returns close to its initial value for the late phase of growth, where the population stabilizes, the viscosity of the mutant strain ...

  13. Results of the thyroid and diabetes-associated autoantibodies screening in children and adolescents living in various regions of Belarus

    International Nuclear Information System (INIS)

    Recently among the factors capable to induce autoimmune reaction, it is ionizing radiation that is discussed, along with virus infections and chemical influences. Investigation of 540 healthy children and adolescents (age range 12-19 y.o.) living in radionuclide contaminated areas (average cesium 137 contamination 0,19-0,56 MBq/m2) and in conditionally clear regions revealed significant differences in levels of diabetes-associated (AB-GAD, AB-IA2) and thyroid (AB-TG, AB-TPO) autoantibodies. At the same time frequencies of positive AB-IA2, AB-TPO and AB-TG were higher in persons from contaminated regions. Obtained results correlate with the increase of the type 1 diabetes incidence in children and adolescents from Gomel region and dictate the necessity to continue the such study

    Full Text Available Introduction The frequency of pediatric and adolescent oral and maxillofacial lesions is various in different societies. The present study aimed at investigating the frequency of oral and maxillofacial pediatric and adolescent biopsies in Zahedan (southeast Iran, and compare the results with other epidemiologic studies.Methods and Materials This retrospective study reviewed oral and maxillofacial lesions in patients with 0-18 years old referring to the treatment centers of Zahedan University of Medical Sciences during 12-years period. Patients’ demographic information including age, gender and location of the lesion were collected and statistically analyzed.ResultsIn general, among 1112 oral and maxillofacial lesions, 154 (13.9% cases were related to children and adolescents younger than 18 years old. The average age of patients was 11.4 ± 4.9, 53.2% and 46.8% of them were boys and girls, respectively. The most frequent sites of lesions were the gingiva and lip. The most prevalent lesions included inflammatory/reactive, cystic and neoplastic lesions, respectively. Benign and malignant tumors comprised 12.3% and 4.5% of cases. Moreover, pyogenic granuloma and peripheral giant cell granuloma (PGCG were the most frequent lesions.ConclusionThe most prevalent oral and maxillofacial lesions in patients under 18 years old were inflammatory/reactive lesions in gingiva and in the 13-18 age range. Determining the characteristics of these lesions in the children and adolescents population provides a firm groundwork for proper diagnosis and treatment.

  15. Religiosity of Muslim Adolescents from Single Parent Families Living in Government-Subsidised Settlement

    2015-12-01

    Full Text Available Adolescence is a phase of emotionl turmoil and stress. If not balanced with religious practice, it may cause adolescents to fall into moral and social problems such as breach of school discipline, delinquency, drug addiction and sexual permissiveness. Religiosity is one way for adolescents to deal with challenges in life thereby avoiding immoral activities. This is because religiosity may help to balance adolescent emotional, cognitive and social developments.The purpose of this study is to identify the behaviour and level of religiosity among 30 adolescents from single parents families who settle in government-subsidised area of residence, namely known as the Federal Land Development Authority (FELDA. The area is located in the state of Pahang, situated on the eastern part of Malaysia. These adolescents have been selected as research respondents. This research was conducted as a survey using questionnaire as the research instrument. It was constructed based on the guidelines of Islamic Practice Instrument (IPI (Fariza, 2012 and has already been verified in terms of its validity and reliability. The data analysis has adopted the method of descriptive statistics explained in table form. The research results have found that religiosity or religious behaviour that the adolescents most frequently abide by are staying away from gambling, having good thoughts and expectations of Allah, feeling awed and fear of Allah’s power (taqwa, staying away from fornication (zina and supplication (doa to Allah facing the direction of Qibla. The level of religiosity is medium for most adolescents. This factor explains why not many respondents are involved in moral and disciplinary problems at school. This research finds that generally, religiosity protects adolescents from being involved in immoral activities and other vices.

  16. Minisatellite mutations and retrospective biodosimetry of population living close to the Semipalatinsk nuclear test site

    International Nuclear Information System (INIS)

    During the period between 1949 and 1989 nuclear weapon testing carried out at the Semipalatinsk Nuclear Test Site (STS) resulted in local fallout affecting the residents of Semipalatinsk, East Kazakhstan and Pavlodar districts of Kazakhstan and Altai region of Russia. The Semipalatinsk nuclear polygon in Kazakhstan has been the site for 470 nuclear tests, including 26 tests performed on the ground and 87 in the atmosphere. More than 1.5 million people living in the vicinity of the test site were repeatedly exposed to ionizing radiation. The paper reviews the study where the main objectives are: (1) to establish a biosample database of blood samples of families in three generations living close to the STS and control families in three generations from clean areas, (2) to determine the minisatellite mutation rates in the three generations of exposed people and the control families of the same ethinic origin living in non-contaminated areas, and (3) to determine the chromosomal translocation frequencies by FISH chromosome painting in the lymphocytes of the exposed and the control people in order to determine the radiation exposure. The aim of the study was to select the population living near to the STS and subjected to the greatest radiation exposure. Of particular interest was the first test of 29th of August 1949, as this was reported to have caused heavy fallout along a narrow trajectory extending north-east from Polygon, also covering parts of the Altai region of Russia and parts of Pavlodar and Karaganda regions in Kazakhstan

    To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension. PMID:16269048

  19. Current radiological simulation and dose assessment on the population living in the Techa Basin

    International Nuclear Information System (INIS)

    In the beginning of the fifties, planned releases of liquid radioactive wastes were performed from the radiochemical enterprise Mayak to the riverbed of the Techa river flowing in the area of the Chelyabinsk region. These releases caused high contamination of the riverbed and water meadows of the Techa river especially by 90Sr and 137Cs. After the termination of intensive releases, a part of the population living in the riverside settlements (15 settlements with total population of 72000 persons) was resettled from 1954-1962. Within the Chelyabinsk region, four inhabited settlements remained on the river: Muslyumovo, Brodokalmak, Russkaya Techa and Nizhnepetropavlovskoye with a total population of 9229 persons according to the census of 1989. The second, but much less significant, source of contamination to this environment was the dispersion and transport of contaminated sediments from Lake Karachay in 1967 [Romanov et al. 1995; Kryshev et al. 1998; Kravtsova et al. 1998]. The overall purpose of this work was determination of ways and estimation of current levels of exposure to population of two settlements, Muslyumovo and Brodokalmak, which is necessary for development of measures on radiation and social protection of population

    We examined the relationship of community, interpersonal, and personal risk and protective factors to substance use among adolescents of parents with HIV (PWH). Families with HIV (n = 269 PWH and 409 adolescents) from New York City were recruited, and multivariate models were used to examine the associations. Adjusting for age, gender, and ethnicity, substance use was positively associated in univariate analyses with parental substance use, family conflict, adolescent emotional distress, and adverse life events; having academically oriented friends and religiosity were protective. In the multivariate model, multiple problem behaviors (e.g., delinquency) and substance-using peers were significantly associated with substance use. The patterns of associations between the risk factors and substance use are similar to those of adolescents in families not impacted by HIV. Interventions aimed at improving parental care, reducing maladaptive peer networks, and decreasing problem behaviors are important strategies to explore in future prevention studies. PMID:21204658

    This study aimed to monitor diet quality and associated factors in adolescents, adults and older adults from the city of São Paulo, Brazil. We conducted a cross-sectional population-based study involving 2376 individuals surveyed in 2003, and 1662 individuals in 2008 (Health Survey of São Paulo, ISA-Capital). Participants were of both sexes and aged 12 to 19 years old (adolescents), 20 to 59 years old (adults) and 60 years old or over (older adults). Food intake was assessed using the 24-h dietary recall method while diet quality was determined by the Brazilian Healthy Eating Index (BHEI-R). The prevalence of descriptive variables for 2003 and 2008 was compared adopting a confidence interval of 95%. The means of total BHEI-R score and its components for 2003 and 2008 were compared for each age group. Associations between the BHEI-R and independent variables were evaluated for each survey year using multiple linear regression analysis. Results showed that the mean BHEI-R increased (54.9 vs. 56.4 points) over the five-year period. However, the age group evaluation showed a deterioration in diet quality of adolescents, influenced by a decrease in scores for dark-green and orange vegetables and legumes, total grains, oils and SoFAAS (solid fat, alcohol and added sugar) components. In the 2008 survey, adults had a higher BHEI-R score, by 6.1 points on average, compared to adolescents. Compared to older adults, this difference was 10.7 points. The diet quality remains a concern, especially among adolescents, that had the worst results compared to the other age groups. PMID:27547722

  4. Self-help countermeasure strategies for populations living within contaminated areas of Belarus, Russia and Ukraine

    International Nuclear Information System (INIS)

    Countermeasures have been effectively employed within intensive agricultural systems in areas of the Former Soviet Union (FSU) affected by the Chernobyl accident. However, ingestion doses continue to be elevated in some areas as a result of few foodstuffs which are collected from the wild or produced by the household. Forest fungi and berries, and milk from privately owned cattle are the most notable contributors to 137Cs intakes amongst these foodstuffs. In this paper we consider advice which would help affected populations to both understand the importance of these exposure routes and to reduce their exposure. In addition to the potential radiological benefits, self-help schemes are highly cost-effective and likely to have a positive psychological influence on populations living within contaminated areas of the FSU. Evidence to suggest that the transfer of radiocaesium to cow milk is considerably higher in the FSU than within western Europe and North America is discussed

    The alarming problem of a decline in physical activity among children and adolescents and its detrimental effects on public health has been well recognised worldwide. Low physical activity is responsible for 6% of deaths worldwide and 5-10% of deaths in the countries of the WHO European Region, according to country. Within the last decade, many initiatives have been launched to counteract this phenomenon. The objective of presented study was analysis of the level of physical activity among adolescents and young adults in Poland, according to the IPAQ questionnaire. The study group covered 7,716 adolescents: 5,086 children attending high school and secondary schools and 2,630 university students. Low physical activity was noted among 57% of schoolchildren and 20.84% of students. Analysis of the level of physical activity according to the IPAQ indicated that it was lower among girls, compared to boys. An additional analysis, with the consideration of the place of residence, showed that the highest percentage of the population with low physical activity was noted in the rural areas (29.30%), while among the urban inhabitants of cities with a population above 100,000 it was on the level of 23.69% and 20.57%. Median for weekly physical activity by respondents" gender was on the level of 1,554.00 MET*min. weekly among females, and 2,611.00 MET*min. weekly among males (pstudents spend significantly more time in a sedentary position, compared to schoolchildren. The presented results of studies indicate the necessity to continue and intensify actions to promote various forms of physical activity among students and schoolchildren. A constant decrease in physical activity observed among children and adolescents suggests that it is necessary to pay greater attention to this social group while developing health programmes.

  6. Population Pressure, Global Living Standards, and the Promise of Space Solar Power

    What many sincere environmentalists advocate: (severe restrictions on energy use, to reduce global warming), may actually end up being very harmful to the environment. Since 85 percent of the global energy use is derived from carbon based fossil fuels, this may seem to be a reasonable position. However, the proponents of energy use restrictions are ignoring some very important relationships. The greatest damage to the environment, in terms of species loss, is loss and/or human modification of habitat. The two greatest threats to habitat seem to be (1) population pressure and (2) logging. Logging does not necessarily permanently occupy the land, while either default squatter occupation or "colonization by policy" is often permanent. Increased population degrades the land by causing over- farming, and also creates an ever greater demand for raw materials and food resources. Poor people have no time nor money to think about or help save the environment. Therefore the greatest threat to species survival is human population growth and its frequent companion: poverty. There is an existing way to reduce population growth, and thus to reduce pressure on habitats, called "raising the standard of living". Wherever it succeeds, population growth slows rapidly. In many European countries, there would be a negative population growth if not for immigration. Personal energy use is closely correlated with living standards, and it is impossible to have a higher living standard without a higher degree of personal energy use. It would seem, however, that extending high living standards to the developing world would create an even greater demand for the use of fossil fuels. The solution to this dilemma can only be found in the use of very high capacity sources of non- fossil energy that do not significantly damage the environment. Are there sources of clean, economical energy with a large enough combined capacity to provide high living standards for the whole world, including those

    The scope of this study is to correlate the gingival condition and sociodemographic status of adolescents living in an economically disadvantaged Brazilian region. The survey was conducted with a random sample of 450 adolescents in 13 cities selected in the Jequitinhonha Valley (State of Minas Gerais). The gingival condition was evaluated using a calibrated examiner (Kappa ≥ 0.85). The oral exam was based on the Community Periodontal Index (CPI). The frequencies of individuals were calculated and sextants subsequently assessed using Multiple Correspondence Analysis (ANACOR) to reveal the relationship between CPI and sociodemographic characteristics. The results showed that: 16 (3.6%) were healthy; 235 (52.2%) had gingival bleeding; 36 (8%) had dental calculus and 163 (36.2%) had both bleeding and calculus. ANACOR identified two groups with similarities in relation to periodontal disease. Group one featured 19-year-olds with healthy CPI who work and have higher family income. Group two included 15- and 16-year-olds of both sexes with CPI and gingival bleeding in elementary school with lower family income, who declared themselves to be of mixed or Afro-descendant race. The presence of gingivitis was related to the socioeconomic and demographic characteristics of adolescents in the region. PMID:26602715

    This study describes and conceptualizes the experiences of stigma in a group of children living with HIV in São Paulo, Brazil, and evaluates the impact of access to highly active antiretroviral therapy (HAART) over the social course of AIDS and over the children's experiences of stigma. Through ethnographic research in São Paulo from 1999 to 2001, the life trajectories of 50 children ages 1-15 living with or affected by HIV were studied. Data were collected via participant observation and semi-structured informal interviews and analyzed using social theories on illness experience and social inequality. Our results demonstrate that AIDS-related stigma occurs within complex discrimination processes that change as children reach adolescence. We found that structural violence in the forms of poverty, racism, and inequalities in social status, gender, and age fuels children's experiences of stigma. We also describe how access to HAART changes the lived experience of children, reduces stigma, and brings new challenges in AIDS care such as adolescents' sexuality and treatment adherence. Based on these results, we propose structural violence as the framework to study stigma and argue that interventions to reduce stigma that solely target the perception and attitudes toward people living with HIV are limited. In contrast universal access to HAART in Brazil is a powerful intervention that reduces stigma, in that it transforms AIDS from a debilitating and fatal disease to a chronic and manageable one, belongs to a broader mechanism to assure citizens' rights, and reduces social inequalities in access to health care.

    The Western Australian (WA) 'LiveLighter' (LL) mass media campaign ran during June-August and September-October 2012. The principal campaign ad graphically depicts visceral fat of an overweight individual ('why' change message), whereas supporting ads demonstrate simple changes to increase activity and eat healthier ('how' to change message). Cross-sectional surveys among population samples aged 25-49 were undertaken pre-campaign (N= 2012) and following the two media waves (N= 2005 and N= 2009) in the intervention (WA) and comparison state (Victoria) to estimate the population impact of LL. Campaign awareness was 54% after the first media wave and overweight adults were more likely to recall LL and perceive it as personally relevant. Recall was also higher among parents, but equal between socio-economic groups. The 'why' message about health-harms of overweight rated higher than 'how' messages about lifestyle change, on perceived message effectiveness which is predictive of health-related intention and behaviour change. State-by-time interactions showed population-level increases in self-referent thoughts about the health-harms of overweight (P < 0.05) and physical activity intentions (P < 0.05). Endorsement of stereotypes of overweight individuals did not increase after LL aired. LL was associated with some population-level improvements in proximal and intermediate markers of campaign impact. However, sustained campaign activity will be needed to impact behaviour.

    In this study, we sought to determine the population stability and genetic diversity of one isolated population of the federally-threatened bog turtle (Glyptemys muhlenbergii) in North Carolina. Using capture-recapture data, we estimated adult survival and population growth rate from 1992 to 2007. We found that the population decreased from an estimated 36 adult turtles in 1994 to approximately 11 adult turtles in 2007. We found a constant adult survival of 0. 893 (SE = 0. 018, 95% confidence interval, 0. 853-0. 924) between 1992 and 2007. Using 18 microsatellite markers, we compared the genetic status of this population with five other bog turtle populations. The target population displayed allelic richness (4. 8 ?? 0. 5) and observed heterozygosity (0. 619 ?? 0. 064) within the range of the other bog turtle populations. Coalescent analysis of population growth rate, effective population size, and timing of population structuring event also indicated the genetics of the target population were comparable to the other populations studied. Estimates of effective population size were a proportion of the census size in all populations except the target population, in which the effective population size was larger than the census size (30 turtles vs. 11 turtles). We attribute the high genetic diversity in the target population to the presence of multiple generations of old turtles. This study illustrates that the demographic status of populations of long-lived species may not be reflected genetically if a decline occurred recently. Consequently, the genetic integrity of populations of long-lived animals experiencing rapid demographic bottlenecks may be preserved through conservation efforts effective in addressing demographic problems. ?? 2011 Springer Science+Business Media B.V.

    2013-01-01

    Full Text Available The objective of this article was to identify the possible constructs of one or more apparatus of sexuality and of alliance in adolescents living in poverty in Brazil. The research methodology was a qualitative assessment using an ethnographic approach. The principal data collection technique, in addition to ethnographic observation and documentary analysis, was face-to-face in-depth interviews. Fourteen adolescents living in the same Belém neighbourhood were observed and interviewed, as well as their parents. The data analysis revealed an apparatus of sexuality as an apparatus of safe sex whereas an apparatus of alliance, according to Foucault, was described after analysis and confirmation of the data as an alliance of powerfulness. These results is bringing new light on the question of the social construct of sexuality among adolescents living in poverty, put into better position the use of Foucault’s concepts, considered till now only as philosophical abstractions, and not as empirical results.

    The proportion of obese adolescents in Southern Appalachia is among the highest in the nation. Through funding from the National Institute on Minority Health and Health Disparities--National Institutes of Health, the Team Up for Healthy Living project was a cluster-randomized trial targeting obesity prevention in adolescents through a cross-peer intervention. The specific aims of the project were to: 1) develop a peer-based health education program focusing on establishing positive peer norms towards healthy eating and physical activity (PA) among high school students, 2) test program efficacy, and 3) explore mechanisms underlying the program. The study was guided by the Theory of Planned Behavior, which presupposes that human behavior is primarily driven by attitude, subjective norms, perceived behavioral control, and social support. To deliver the intervention, undergraduate students from the disciplines of public health, nutrition, and kinesiology were hired as peer facilitators. Ten area high schools were invited to participate, were matched on demographics and then randomized to intervention or control. The primary outcomes of the study included body mass status, dietary behaviors, PA, and sedentary behaviors which were assessed at baseline and at three and twelve months post baseline. Intervention schools received Team Up for Healthy Living curriculum, which consists of eight 40-minute sessions. The curriculum focused on improving nutrition awareness, PA, leadership and communication. Control schools received their regularly scheduled Lifetime Wellness curriculum. The long-term goal of the study was to establish an effective academia-community partnership program to address adolescent obesity disparity in Southern Appalachia. PMID:25937506

    Using data from the Korea Youth Risk Behavior Web-based Survey, this study seeks to investigate associations of suicide attempts with family, individual, and behavioral factors on the basis of gender. Among male adolescents, those who did not live with their parents, who had poor subjective academic achievement, depression, experiences of smoking and sexual coitus, drug abuse, suicidal ideation and plans were more likely to attempt suicide. Among the female adolescents, those who did not live with their parents, had depression, low self-rated health, experiences of drug abuse and sexual coitus, and expressed unhappiness, suicidal ideation and suicide plans were more likely to attempt suicide. Thus, the development of a suicide prevention program for Korean adolescents requires different approaches for males and females. PMID:25812547

    Full Text Available Background: Noise is an environmental pollution agent to which a high percentage of the urban population, as well as residents living around important sources of noise, are exposed.Methods: A cross-sectional study was carried out to measure the perception of noise of the residents living in the area of the bay of Pasaia (Guipuzkoa, Spain. 351 dwellings were randomly selected. A structured questionnaire was used to gather information about the respondent self-perception of annoyance and sensitivity to noise. The sound pressure levels were estimated using a model that took into account the main characteristics of the different sources of noise.Results: 37.5% of the sample reported to be annoyed by noise. The interviewees declared that the main sourceof annoyance was the traffic (60% followed by the activity in the harbour (24%. The annoyance attributed tonoise was not correlated with the estimated sound level, but with the level of sensitivity to this physical agent(r=0.36; p<0.01. The percentage of the population that showed that the noise levels interfered with activities like getting to sleep was not high (9.5%. Nevertheless, half of the interviewees had already installed in their houses some kind of protection against noise.Conclusions: The relationship among the degree of annoyance caused by noise, the sensitivity to noise, the sound levels and other social and demographic variables show a very interrelated and complex phenomenon. The fact that half of the population had taken any measure to protect them from noise could have mitigated the percentage of people that declare to be annoyed by noise.

    Full Text Available ABSTRACT Objective: To evaluate changes in food intake after adolescents attended a food and nutrition education program at a non-profit institution. Methods: Fifty-four adolescents aged 16 to 19 years, of low socioeconomic level, enrolled in an non-governmental organization in São Paulo, underwent a nutritional intervention of six months consisting of six meetings with dieticians, as well as strategic communication and relationship actions. Body weight, height, body mass index, questionnaire on knowledge on nutrition and feeding practices, 24-hour recall, and diet quality assessment using the Diet Quality Index associated with the Digital Food Guide were collected at baseline and after the intervention. Dietary pattern improvement was defined as an increase of at least 5 points in Diet Quality Index associated with the Digital Food Guide. Results: Understanding of food labels increased, and the dietary patterns on weekdays and weekends improved by 33 and 37%, respectively. The intake of legumes, milk, dairy products, fruits, and vegetables increased (adequacy components. However, intakes of nuts and whole grains were low, and intake of moderation components was high. Conclusion: The program improved the dietary patterns of adolescents, making it a viable and inexpensive method to prevent disease and improve health and quality of life. In addition, the Diet Quality Index associated with the Digital Food Guide has proven to be a good nutritional tool for assessing changes in food intake and for guiding future counseling and nutritional intervention actions for this population.

    Full Text Available Objectives. The aim of the present study was to investigate the relationship between eating behaviors and overweight among population-based adolescents in Japan. Methods. Study subjects comprised adolescents in the seventh grade (age range, 12–13 years from Ina, a town in Saitama Prefecture, Japan, between 1999 and 2008. The height and weight of the subjects were measured, and information concerning eating behaviors (eating speed and eating until full was obtained using a self-administered questionnaire. Results. Among boys (n=1586, fast eating speed significantly increased the odds ratio (OR for overweight when compared with medium eating speed, regardless of eating until full or not; moreover, a more marked increase in the OR was observed among boys eating until full (OR: 2.78, 95% confidence interval: 1.76–4.38 than among those not eating until full (2.43, 1.41–4.20. Among girls (n=1542, fast eating speed led to a significant increase in the OR in those eating until full; however, no significant increases were observed in the OR in those eating quickly and not until full. Conclusions. Among adolescents, fast eating speed was associated with overweight; furthermore, the combination of both fast eating speed and eating until full may have a significant effect on overweight.

    In order to disentangle the contribution of host and parasite biology to host specificity, we compared the structure and population dynamics of the Gyrodactylus (von Nordmann, 1832) flatworm community living on sympatric three-spined Gasterosteus aculeatus L. and nine-spined Pungitius pungitius (L.) stickleback. Between April 2002 and March 2003, a small lowland creek was sampled monthly. Species identity of about 75% of the worms per host was determined with a genetic nuclear marker (ITS1). Each stickleback species hosted a characteristic gill- and fin-parasitic Gyrodactylus: G. arcuatus Bychowsky, 1933 and G. gasterostei Gläser, 1974 respectively infecting the three-spined stickleback, with G. rarus Wegener, 1910 and G. pungitii Malmberg, 1964 infecting the nine-spined stickleback. Host size and seasonal dynamics were strong determinants of parasite abundance. A strong interaction between host and parasite species determined infection levels and affected three levels of parasite organisation: community structure, population structure and topographical specialisation. Community and population structure were shaped by asymmetric cross-infections, resulting in a net transmission of the Gyro-dactylus species typical of the nine-spined stickleback towards the three-spined stickleback. Host density was not a major determinant of parasite exchange. Aggregation and topographical specialisation of the Gyrodactylus species of the three-spined stickleback were more pronounced than that of the nine-spined stickleback. PMID:19202677

    Healthcare in Canada has generally not kept pace with the evolving needs of patients since the creation of medicare in the 1960s. Budgets for hospitals, physicians and prescription drugs make up the bulk of spending in health, despite the need for better prevention and management of chronic disease, the needed expansion of home-based care services and the call for reform of front-line primary care. Over the past decade, a number of Canadian health authorities have adopted the US-based Institute for Healthcare Improvement Triple Aim philosophy (better population health, better patient experience and better per capita cost of care) in order to build system-level change. The Atlantic Healthcare Collaboration was one attempt to initiate system-level reform in healthcare delivery for patients living with chronic disease. PMID:27009641

    Florida has the greatest proportion (19%) of older population (65 years or older) in the United States. The age distribution of its residents, in conjunction with a major shift in the leading cause of death within all age groups from acute illnesses to chronic disease, creates unprecedented health care challenges for the state. The objective of this study is to profile the older population living in Miami-Dade County (MDC) using 3 population-based, household-based surveys conducted over the past 5 years.This study examined cross-sectional data (demographics, health outcomes, risk factors, health assess, and utilization) collected from probability-sampled, household-based surveys conducted in 3 areas of MDC: north Miami-Dade, Little Haiti, and South Miami. The questionnaire was administered face-to-face by trained interviewers in English, Spanish, French, or Creole. Analyses were restricted to households containing at least 1 member aged 65 years or older (n = 935). One consenting adult answered the questionnaire on behalf of household members.The mean age of the respondent (60% females) was 60 years. Overall, respondents were predominantly African-Americans, Hispanics, and blacks of Haitian origin. One-third of all households fell below the US poverty thresholds. One-quarter of all households had at least 1 member who was uninsured within the year before the survey. Twenty percent of households had at least 1 member with an acute myocardial infarction or stroke during the year before the survey. Bone density tests and blood stool tests were strikingly underutilized. The health outcomes most prevalent within household members were cardiovascular diseases followed by cancer, anxiety/depression, obesity, asthma, and bone fractures. Twenty percent of households reported having at least 1 current smoker. Overall, emergency rooms were the most commonly used places of care after doctor's offices.Findings of 3 household-based surveys show a predominantly elderly

    The objectives of the study were to determine minisatellite mutation rates in families in three generations and to perform retrospective biodosimetry of individuals in these families living close to the Semipalatinsk nuclear test site in Kazakhstan. The oldes generation (Po) lived in the area at the time of the first Soviet nuclear test in 1949 whereas the younger generations (F1,F2) were exposed to smaller doses from the residual fallout and later tests. Matched control families in three generations living in non-contamianted areas were analysed in parallel. The retrospective biodosimetry comprehended two endpoints; chromosomal translocations determined by FISH chromosome painting and the glycophorin A (GPA) somatic mutation assay. The minisatellite mutation rate in the cohort of P0 parents was 1-8-fold higher than in the control non-exposed population. Moreover, the minisatellite mutatin rate in the cohort of f1 parents from the exposed area showed a significant negative correlation with with the year of birth, fully consistent with the decay of radioisotopes after the cessation of surface and atmospheric nuclear tests. The results from the FISH painting analysis showed similar translocation frequencies in the Semipalatinsk cohort and the control group. Based on the FISH results it can be concluded that the P0 generation has received a cumulative mean dose of less than 0.5 Gy. The GPA assay did not reveal significant diffrences in the variant cell frequencies for all subjects from the Semipalatinsk area compared with the matched controls. However, a significant increase (P<0.05) of the mean allele-loss {phi}N variant frequency was observed among the exposed P0 generation in comparison to controls. Considering the sensitivity of the GPA assay, the results suggest that the mean dose to the P0 generation of the affected villages was relatively low and in accordance to the results obtained using FISH.

    Background Low birthweight (LBW) is associated with increased mortality in infancy, but its association with mortality in later childhood and adolescence is less clear. We investigated the association between birthweight and all-cause mortality and identified major causes of mortality for different birthweight groups. Methods and Findings We conducted a population study of all live births occurring in England and Wales between 1 January 1993 and 31 December 2011. Following exclusions, the 12,355,251 live births were classified by birthweight: 500–1,499 g (very LBW [VLBW], n = 139,608), 1,500–2,499 g (LBW, n = 759,283), 2,500–3,499 g (n = 6,511,411), and ≥3,500 g (n = 4,944,949). The association of birthweight group with mortality in infancy (adolescence (1–18 y of age) was quantified, with and without covariates, through hazard ratios using Cox regression. International Classification of Diseases codes identified causes of death. In all, 74,890 (0.61%) individuals died between birth and 18 y of age, with 23% of deaths occurring after infancy. Adjusted hazard ratios for infant deaths were 145 (95% CI 141, 149) and 9.8 (95% CI 9.5, 10.1) for the VLBW and LBW groups, respectively, compared to the ≥3,500 g group. The respective hazard ratios for death occurring at age 1–18 y were 6.6 (95% CI 6.1, 7.1) and 2.9 (95% CI 2.8, 3.1). Male gender, the youngest and oldest maternal age bands, multiple births, and deprivation (Index of Multiple Deprivation score) also contributed to increased deaths in the VLBW and LBW groups in both age ranges. In infancy, perinatal factors, particularly respiratory issues and infections, explained 84% and 31% of deaths in the VLBW and LBW groups, respectively; congenital malformations explained 36% and 23% in the LBW group and ≥2,500 g groups (2,500–3,499 g and ≥3,500 g groups combined), respectively. Central nervous system conditions explained 20% of deaths in childhood/adolescence in the VLBW group, with deaths from

  13. Internal exposure of populations to long-lived radionuclides released into the environment

    International Nuclear Information System (INIS)

    This chapter discusses the events that led to the contamination of environments with the long-lived radionuclides of caesium, strontium and other elements, and to the internal exposure of populations living in contaminated areas. Among these events are radioactive releases into the river Techa from the Soviet nuclear weapons facility Mayak in 1949-1956, thermonuclear weapons test in the 1950s and 1960s, the Kyshtim and Windscale accidents in 1957, and the Chernobyl and Tomsk-7 accidents in 1986 and 1993, respectively. Methods of environmental monitoring and individual internal dose monitoring of inhabitants are described. These are based on measuring the content of radionuclides not only in the air, drinking water and local food products, but also in humans using whole-body counters and analysing excreta and autopsy samples. The dynamics of internal exposure of people of different ages to radionuclides of caesium, strontium and plutonium from the environment are considered. Examples of radionuclide distributions in the environment, and of individual/collective internal doses and related medical effects are presented. (Author)

    2008-06-01

    From long ago, the Maya civilizations of Mesoamerica have been keenly attuned to the cycles of nature. The Maya have always been careful observers, and more than a thousand years ago, they recorded the motion of the planets, the Sun, and the Moon, and predicted eclipses. These observations were used to create a complex calendar to organize the events of their world. The Maya built great cities containing buildings aligned with the Sun, Moon, and the stars to mark important times of the year. Many astronomical traditions are still practiced today by the Maya of the Yucatán peninsula, Southern states in México, and other areas in Mesoamerica. Traditional farming communities time the cultivation of corn by observing the sky. The living culture of the Mayan people in the Yucatan integrates science and astronomy with every other aspect of their culture. Yucatec Maya, the language spoken by more than 1 million people in the Yucatán today, still carries through oral histories the ancient knowledge of nature. Our hope is that you'll increase your interest and knowledge of the Mayan people and of the enduring wisdom reflected in the daily lives of Mayan families. We present the results of education and public outreach efforts that position astronomy within its cultural context as an effective means of capturing the interest and enabling authentic participation of under-represented populations in science.

  15. Live and non-live pregnancy outcomes among women with depression and anxiety: a population-based study.

    Lu Ban

    Full Text Available BACKGROUND: Women taking antidepressant or anti-anxiety medications during early pregnancy have high risks of non-live pregnancy outcomes, although the contribution of the underlying illnesses to these risks remains unclear. We examined the impacts of antenatal depression and anxiety and of commonly prescribed treatments on the risks of non-live pregnancy outcomes. METHODS: We identified all pregnancies and their outcome (live birth, perinatal death, miscarriage or termination among women aged 15-45 years between 1990 and 2009 from a large primary care database in the United Kingdom. Women were grouped according to whether they had no history of depression and anxiety, a diagnosis of such illness prior to pregnancy, illness during pregnancy and illness during pregnancy with use of medication (stratified by medication type. Multinomial logistic regression models were used to compare risks of non-live outcomes among these groups, adjusting for major socio-demographic and lifestyle characteristics. RESULTS: Among 512,574 pregnancies in 331,414 women, those with antenatal drug exposure showed the greatest increased risks for all non-live pregnancy outcomes, relative to those with no history of depression or anxiety, although women with prior (but not currently medicated illness also showed modest increased risks. Compared with un-medicated antenatal morbidity, there was weak evidence of an excess risk in women taking tricyclic antidepressants, and stronger evidence for other medications. CONCLUSIONS: Women with depression or anxiety have higher risks of miscarriage, perinatal death and decisions to terminate a pregnancy if prescribed psychotropic medication during early pregnancy than if not. Although underlying disease severity could also play a role, avoiding or reducing use of these drugs during early pregnancy may be advisable.

  16. Adolescent girls and young women: key populations for HIV epidemic control

    Directory of Open Access Journals (Sweden)

    Full Text Available Introduction: At the epicentre of the HIV epidemic in southern Africa, adolescent girls and young women aged 15–24 contribute a disproportionate ~30% of all new infections and seroconvert 5–7 years earlier than their male peers. This age–sex disparity in HIV acquisition continues to sustain unprecedentedly high incidence rates, and preventing HIV infection in this age group is a pre-requisite for achieving an AIDS-free generation and attaining epidemic control. Discussion: Adolescent girls and young women in southern Africa are uniquely vulnerable to HIV and have up to eight times more infection than their male peers. While the cause of this vulnerability has not been fully elucidated, it is compounded by structural, social and biological factors. These factors include but are not limited to: engagement in age-disparate and/or transactional relationships, few years of schooling, experience of food insecurity, experience of gender-based violence, increased genital inflammation, and amplification of effects of transmission co-factors. Despite the large and immediate HIV prevention need of adolescent girls and young women, there is a dearth of evidence-based interventions to reduce their risk. The exclusion of adolescents in biomedical research is a huge barrier. School and community-based education programmes are commonplace in many settings, yet few have been evaluated and none have demonstrated efficacy in preventing HIV infection. Promising data are emerging on prophylactic use of anti-retrovirals and conditional cash transfers for HIV prevention in these populations. Conclusions: There is an urgent need to meet the HIV prevention needs of adolescent girls and young women, particularly those who are unable to negotiate monogamy, condom use and/or male circumcision. Concerted efforts to expand the prevention options available to these young women in terms of the development of novel HIV-specific biomedical, structural and behavioural

    Psychological distress is common among adolescents living with HIV (ALHIV) worldwide, and has been associated with non-adherence to anti-retroviral therapy (ART), leading to poor virologic suppression, drug resistance, and increased risk for AIDS morbidity and mortality. However, only a few studies have explored the relationship between psychological distress and ART adherence among adolescents in sub-Saharan Africa. The paper examines the relationship between psychological distress and ART adherence, and effect of psychosocial resources on ART adherence. We conducted a cross-sectional survey of 464 ALHIV (aged 12-19; 53% female) seeking HIV care at a large HIV treatment center in Kampala, Uganda. ALHIV were recruited during routine clinic visits. Three self-reported binary adherence measures were utilized: missed pills in the past three days, non-adherence to the prescribed medical regimen, and self-rated adherence assessed using a visual analog scale. Psychological distress was measured as a continuous variable, and computed as the mean score on a locally developed and validated 25-item symptom checklist for Ugandan ALHIV. Psychosocial resources included spirituality, religiosity, optimism, social support, and coping strategies. After adjusting for respondents' socio-demographic characteristics and psychosocial resources, a unit increase in psychological distress was associated with increased odds of missing pills in past 3 days (Odds Ratio(OR) = 1.75; Confidence Interval (CI): 1.04-2.95), not following the prescribed regimen (OR = 1.63; CI: 1.08-2.46), and lower self-rated adherence (OR = 1.79; CI: 1.19-2.69). Psychosocial resources were associated with lower odds for non-adherence on all three self-report measures. There is a need to strengthen the psychosocial aspects of adolescent HIV care by developing interventions to identify and prevent psychological distress among Ugandan ALHIV. PMID:27294696

    The activity of growing living bacteria was investigated using real-time and in situ rheology—in stationary and oscillatory shear. Two different strains of the human pathogen Staphylococcus aureus—strain COL and its isogenic cell wall autolysis mutant, RUSAL9—were considered in this work. For low bacteria density, strain COL forms small clusters, while the mutant, presenting deficient cell separation, forms irregular larger aggregates. In the early stages of growth, when subjected to a stationary shear, the viscosity of the cultures of both strains increases with the population of cells. As the bacteria reach the exponential phase of growth, the viscosity of the cultures of the two strains follows different and rich behaviors, with no counterpart in the optical density or in the population's colony-forming units measurements. While the viscosity of strain COL culture keeps increasing during the exponential phase and returns close to its initial value for the late phase of growth, where the population stabilizes, the viscosity of the mutant strain culture decreases steeply, still in the exponential phase, remains constant for some time, and increases again, reaching a constant plateau at a maximum value for the late phase of growth. These complex viscoelastic behaviors, which were observed to be shear-stress-dependent, are a consequence of two coupled effects: the cell density continuous increase and its changing interacting properties. The viscous and elastic moduli of strain COL culture, obtained with oscillatory shear, exhibit power-law behaviors whose exponents are dependent on the bacteria growth stage. The viscous and elastic moduli of the mutant culture have complex behaviors, emerging from the different relaxation times that are associated with the large molecules of the medium and the self-organized structures of bacteria. Nevertheless, these behaviors reflect the bacteria growth stage.

    Full Text Available BACKGROUND: The number of people living with HIV (PLHIV is increasing in the UK. This study estimated the annual population cost of providing HIV services in the UK, 1997-2006 and projected them 2007-2013. METHODS: Annual cost of HIV treatment for PLHIV by stage of HIV infection and type of ART was calculated (UK pounds, 2006 prices. Population costs were derived by multiplying the number of PLHIV by their annual cost for 1997-2006 and projected 2007-2013. RESULTS: Average annual treatment costs across all stages of HIV infection ranged from £17,034 in 1997 to £18,087 in 2006 for PLHIV on mono-therapy and from £27,649 in 1997 to £32,322 in 2006 for those on quadruple-or-more ART. The number of PLHIV using NHS services rose from 16,075 to 52,083 in 2006 and was projected to increase to 78,370 by 2013. Annual population cost rose from £104 million in 1997 to £483 million in 2006, with a projected annual cost between £721 and £758 million by 2013. When including community care costs, costs increased from £164 million in 1997, to £683 million in 2006 and between £1,019 and £1,065 million in 2013. CONCLUSIONS: Increased number of PLHIV using NHS services resulted in rising UK population costs. Population costs are expected to continue to increase, partly due to PLHIV's longer survival on ART and the relative lack of success of HIV preventing programs. Where possible, the cost of HIV treatment and care needs to be reduced without reducing the quality of services, and prevention programs need to become more effective. While high income countries are struggling to meet these increasing costs, middle- and lower-income countries with larger epidemics are likely to find it even more difficult to meet these increasing demands, given that they have fewer resources.

    Full Text Available Abstract Background Many people who have suffered a stroke require rehabilitation to help them resume their previous activities and roles in their own environment, but only some of them receive inpatient or even outpatient rehabilitation services. Partial and unmet rehabilitation needs may ultimately lead to a loss of functional autonomy, which increases utilization of health services, number of hospitalizations and early institutionalization, leading to a significant psychological and financial burden on the patients, their families and the health care system. The aim of this study was to explore partially met and unmet rehabilitation needs of older adults who had suffered a stroke and who live in the community. The emphasis was put on needs that act as obstacles to social participation in terms of personal factors, environmental factors and life habits, from the point of view of four target populations. Methods Using the focus group technique, we met four types of experts living in three geographic areas of the province of Québec (Canada: older people with stroke, caregivers, health professionals and health care managers, for a total of 12 groups and 72 participants. The audio recordings of the meetings were transcribed and NVivo software was used to manage the data. The process of reducing, categorizing and analyzing the data was conducted using themes from the Disability Creation Process model. Results Rehabilitation needs persist for nine capabilities (e.g. related to behaviour or motor activities, nine factors related to the environment (e.g. type of teaching, adaptation and rehabilitation and 11 life habits (e.g. nutrition, interpersonal relationships. The caregivers and health professionals identified more unmet needs and insisted on an individualized rehabilitation. Older people with stroke and the health care managers had a more global view of rehabilitation needs and emphasized the availability of resources. Conclusion Better

  6. A population-based study of anxiety as a precursor for depression in childhood and adolescence

    2004-12-01

    Full Text Available Background Anxiety and depression co-occur in children and adolescents with anxiety commonly preceding depression. Although there is some evidence to suggest that the association between early anxiety and later depression is explained by a shared genetic aetiology, the contribution of environmental factors is less well examined and it is unknown whether anxiety itself is a phenotypic risk factor for later depression. These explanations of the association between early anxiety and later depression were evaluated. Methods Anxiety and depressive symptoms were assessed longitudinally in a U.K. population-based sample of 676 twins aged 5–17 at baseline. At baseline, anxiety and depression were assessed by parental questionnaire. Depression was assessed three years later by parental and adolescent questionnaire. Results Shared genetic effects between early anxiety and later depression were found. A model of a phenotypic risk effect from early anxiety on later depression provided a poor fit to the data. However, there were significant genetic effects specific to later depression, showing that early anxiety and later depression do not index entirely the same genetic risk. Conclusions Anxiety and depression are associated over time because they share a partly common genetic aetiology rather than because the anxiety phenotype leads to later depression.

    Full Text Available Background: The purpose of this study was to evaluate the validity and reliability on the Persian translation of the Modifiable Activity Questionnaire (MAQ in a sample of Tehranian adolescents. Methods: Of a total of 52 subjects, a sub-sample of 40 participations (55.0% boys was used to assess the reliability and the validity of the physical activity questionnaire. The reliability of the two MAQs was calculated by intraclass correlation coefficients, and validation was evaluated using Pearson correlation coefficients to compare data between mean of the two MAQs and mean of four physical activity records. Results: Intraclass correlation coefficient was calculated to assess the reliability between two MAQs and the results of leisure time physical activity over the past year were 0.97. Pearson correlation coefficients between mean of two MAQs and mean of four physical activity records were 0.49 (P < 0.001, for leisure time physical activities. Conclusions: High reliability and relatively moderate validity were found for the Persian translation of the MAQ in a Tehranian adolescent population. Further studies with large sample size are suggested to assess the validity more precisely.

    The purpose of this article is to share current knowledge about adolescent self-mutilation (SM), and to discuss treatment approaches for affected teens and young adults. One in eight American teenagers experiences depression or anxiety. The growing phenomenon of SM is a particularly worrisome coping mechanism used by teens and young adults to deal with stress and sadness. The incidence of SM is increasing, and might be fueled by current trends in music and media that highlight violent and self-injurious behaviors. SM represents a "cry for help" by adolescents who are suffering. Self-mutilators who repeatedly cut themselves with razors, scissors, knives, or sharp glass are not attempting suicide, but are seeking to relieve extreme anxiety, tension, or pain. Medical literature regarding SM is limited, and evidence-based treatment approaches have not been documented; however, early discovery of SM and the development of a multifaceted treatment approach that incorporates the child, family, and trusted practitioners could be instrumental in managing SM. There is hope that antidepressant medications may also be beneficial. Research is needed to identify successful treatment approaches, and to discover the best ways to educate teens, families, educators, and community leaders about the prevalence of SM in our youth.

  13. Influence of industrial heavy metal pollution on soil free-living nematode population

    International Nuclear Information System (INIS)

    The effect of distance from a heavy metal pollution source on the soil nematode community (trophic structure, sex structure, and taxa composition) was investigated along a 15-km transect originating at the Almalyk Industrial Complex, Uzbekistan (pollution source). The soil nematode community was exposed to heavy metal influence both directly and through soil properties changes. Pollution effect on the density and biomass of soil free-living nematodes was found to be highest at pollution source, with fungivores and plant parasites dominating at the upper and deeper soil layers next to the pollution source. These groups decreased along the transect, yielding domination to bacteria- and fungi-feeders. The sex ratio of nematode communities was found to be dependent on heavy metal pollution levels, with the juveniles being the most sensitive nematode group. The Maturity and modified Maturity Indices, reflecting the degree of disturbance of the soil ecosystem, were found to be the most sensitive indices. - Trophic structure and sex ratio of soil nematode population are sensitive tools for monitoring industrial pollution

    From January 1993 to June 1996, the epidemiology of myxomatosis and viral haemorrhagic disease (VHD) was studied in a free-living population of wild rabbits (Oryctolagus cuniculus) in Spain by means of serological surveys and radiotracking. Myxomatosis was endemic and associated with the breeding period. Its serological pattern was characterised by a 100 per cent prevalence of antibodies in adult rabbits and a rapid increase in antibodies in young rabbits in their first year. No mortality from myxomatosis was detected in adults, and mortality in young rabbits could not be estimated because of interference by predators and scavengers and the deaths of many radiotagged rabbits inside their burrows. VHD was also an endemic disease associated with the breeding period. Adults had a higher prevalence of antibodies against VHD than young rabbits, reaching values of 80 to 90 per cent. During the study, there was an increase in rabbit numbers as a result of a decrease in mortality from predation which was associated with an increase in mortality due to VHD and in the prevalence of antibodies to VHD. Mortality from VHD was lower in rabbits with VHD antibodies than in seronegative rabbits, but some mortality from the disease was also detected in seropositive rabbits. The annual mean mortality rate due to VHD in adult rabbits was estimated to be 21.8 per cent. PMID:12135072

    The purpose of researches is determination of dynamics, the forecasting of radiation conditions and studying of radionuclides behaviour in objects of an environment and on this basis to receive data for construction of the maps of radiation conditions, zoning of radioactive contaminated territories, development of the practical recommendations for rational and safe nature use, as well as to estimate influence of radiation conditions on a live of organisms. The factors influencing on radionuclides migration in various ecosystems are determined. It has allowed to use a part of natural resources on radioactive contaminated territories and due to this partially to keep economic potential of the having suffered regions or to exclude them from use. The recommendations for preservation and use of flora and fauna objects, including game animals, fish resources, food, medicinal and fodder plants, mushrooms and others are published. The new data on action of real radioecological conditions on organisms have given a scientific basis for understanding, estimation and decrease of medical biological consequences of radioactive accidents. For increase of the organism stability to action of irradiations the biologically active substances of a natural origin are offered. Are given the results of researches carried out in Belarus in 1997 on the following directions: study of the radioisotopes behaviour dynamics in environment (air, water, ground), ecosystems and populated areas; optimization of the system of radiation ecological monitoring in the republic and scientific methodical ways of it fulfilling; study of effects of low doze irradiation and combined influences, search of ways for correction of the diseases

    Background Smoking scenes in movies promote adolescent smoking onset; thus, the analysis of the number of images of smoking in movies really reaching adolescents has become a subject of increasing interest. Objective The aim of this study was to estimate the level of exposure to images of smoking in movies watched by adolescents in Argentina and Mexico. Methods First-year secondary school students from Argentina and Mexico were surveyed. One hundred highest-grossing films from each year of the period 2009-2013 (Argentina) and 2010-2014 (Mexico) were analyzed. Each participant was assigned a random sample of 50 of these movies and was asked if he/she had watched them. The total number of adolescents who had watched each movie in each country was estimated and was multiplied by the number of smoking scenes (occurrences) in each movie to obtain the number of gross smoking impressions seen by secondary school adolescents from each country. Results Four-hundred and twenty-two movies were analyzed in Argentina and 433 in Mexico. Exposure to more than 500 million smoking impressions was estimated for adolescents in each country, averaging 128 and 121 minutes of smoking scenes seen by each Argentine and Mexican adolescent, respectively. Although 15, 16 and 18-rated movies had more smoking scenes in average, movies rated for younger teenagers were responsible for the highest number of smoking scenes watched by the students (67.3% in Argentina and 54.4% in Mexico) due to their larger audience. Conclusion At the population level, movies aimed at children are responsible for the highest tobacco burden seen by adolescents.

    Remarkable public health achievements to reduce infant and child mortality as well as improve the health and well-being of children worldwide have successfully resulted in increased survival and a growing population of young people aged 10-24 years. Population trends indicate that the current generation of 1.8 billion young people is the largest in history. However, there is a scarcity of dedicated resources available to effectively meet the health needs of adolescents and young adults worldwide. Growing recognition of the pivotal roles young people play in the cultures, societies, and countries in which they live has spurred an expanding global movement to address the needs of this special population. Building an effective global workforce of highly-skilled adolescent health professionals who understand the unique biological, psychological, behavioral, social, and environmental factors that affect the health of adolescents is a critical step in addressing the health needs of the growing cohort of young people. In this review, we aim to: 1) define a global assessment of the health needs for adolescents around the world; 2) describe examples of current training programs and requirements in adolescent medicine; 3) identify existing gaps and barriers to develop an effective adolescent health workforce; and 4) develop a call for targeted actions to build capacity of the adolescent health workforce, broaden culturally relevant research and evidence-based intervention strategies, and reinforce existing interdisciplinary global networks of youth advocates and adolescent health professionals to maximize the opportunities for training, research, and care delivery.

    Full Text Available Background. Despite the frequency of traumatic or stressful events experienced by refugee children and adolescents prior to migration and following resettlement, the majority do not experience mental health problems emphasising the critical nature of resilience. While a host of factors deemed to be protective of mental health in young refugees have been identified, there has been little research exploring the role of resilience as a distinct psychological construct. This study aimed to explore the nature of psychological resilience in refugee adolescents and the relationship between resilience and depression, other emotional and behavioural problems, and mental health service uptake. Method. One hundred and seventy multiethnic refugee adolescents aged 13–17 from South Australia were administered a survey comprising the Connor-Davidson Resilience Scale (CD-RISC, Children’s Depression Inventory (CDI, and Strengths and Difficulties Questionnaire (SDQ. Results. Females tended to have higher resilience, as did those adolescents who had been living in Australia longer. Adolescents suffering from depressive symptoms or other emotional or behavioural problems had lower resilience. There was little evidence of an association between resilience scores and exposure to trauma or service utilisation. Discussion. Fostering resilience may be critical to efforts to prevent or reduce mental health problems in refugee adolescents.

  5. Determination of mercury and selenium in hair samples of Brazilian Indian populations living in the Amazonic region by NAA

    International Nuclear Information System (INIS)

    Biomonitoring of mercury contamination of Brazilian Indian population groups living in the Xingu Park, a reservation situated in the Amazonic region, has revealed very high levels of mercury in hair samples as compared to controls. Total mercury was determined by INAA in most of the tribes living in the Park and methylmercury was determined by CVAAS in samples with total mercury above 10 mg/kg. Due to the fact that selenium seems to protect animals against the toxic effects of methylmercury, it was considered also of interest to determine its concentrations in the hair samples with very high mercury levels. Selenium was determined by INAA via the short-lived radionuclide 77mSe (T1/2 = 17.45 s). The correlations between selenium and mercury concentrations in Brazilian controls and in the Indian population groups are discussed. (author)

    Population education, including family life responsibility and some discrete sexual education, has been introduced for the 1st time in China to selected senior high school students in the 1981-82 academic year. The course covers units on Marxist population theory and the dynamics of population growth from a national and international perspective. Emphasis is placed on the interrelationship of China's 4 modernization programs and the basics of birth control. Particular emphasis is on the promotion of the 1-child family concept and the improvement of population quality through eugenic control. The new course is designed specifically for adolescents and is intended to lay the groundwork for acceptable social sexual behavior for senior high school students (16-17 years of age). The UN Fund for Population Activities (UNFPA) has contributed significantly during the past 2 years to the development of population studies and demographic research within China. It has assisted with research, computer studies, and personnel training for the 1982 census. It also has trained demographers and assisted in the establishment of new population institutes at 10 key universities in various parts of China. The UNFPA program for high schools has earmarked funds for the training of some 8000 teachers in a series of month long workshops, 10 day orientation courses for administrators, the development of modern audiovisual facilities, and reference materials for 10 teacher training institutes, the production of instructional materials for 10 key or pilot middle school programs, and the development of a revised middle school curriculum in such fields as biology, geography, hygiene, physiology, and political study. The new text book, "Population Education," explores openly the many familial problems which will confront China's children in the future. The text rigorously promotes the 1 child family concept as the social and national ideal. The book includes straightforward information on human

    The study of the features reactions of the animals a differing complicated individual development (metamorphosis) and living in conditions of radioactive contamination is an important trend in the modern radio-ecology. This information is of interest not only from the point of view of detection the mechanisms of radiobiological effects (hyper-radiosensitivity, hormesis, radio-adaptation, etc.) but also viewpoint of predicting delayed radiation effects that is necessary at account the normalization of technogeneous loading on natural ecosystems. An assessment of the level of cytogenetic damages (single-strand and double-strand DNA breaks) in the blood cells of tadpoles of Rana arvalis living in areas contaminated of wastes radium production (Russia, Komi Republic, Ukhta district) was conducted. Using this biological matter as a bioindicator due to the fact that development amphibian is carried out by metamorphosis and includes larval stage. At this stage post-embryonic development of an individual are the most sensitive to anthropogenic impact. To exclude the effects of other factors (temperature, age-specific peculiarities, overpopulation, etc.) on the formation of DNA damages from the studied reservoirs were taken laying eggs of amphibians (12-15 egg laying from the area) which afterwards are contain in strictly controlled laboratory conditions using water, belt silt, plants of native pond. The reaction of amphibians on the contamination was assessed by the level of DNA damage by method Comet assay was determined. With each egg laying were selected for 7 even-aged individuals. Total for cytogenetic analysis was used 189 individuals. It is shown that in animals that develop on the radio-contaminated area the level of single-strand DNA (alkaline pH version of the Comet assay) was higher than in the control area. According an estimate to the level of double-strand DNA (neutral pH version of the Comet assay) significant differences not was found. The high variability

    Ballet dancing is a multifaceted activity requiring muscular power, strength, endurance, flexibility, and agility; necessitating demanding training schedules. Furthermore dancers may be under aesthetic pressure to maintain a lean physique, and adolescent dancers require extra nutrients for growth and development. This cross-sectional study investigated the nutritional status of 47 female adolescent ballet dancers (13-18 years) living in Auckland, New Zealand. Participants who danced at least 1 hr per day 5 days per week completed a 4-day estimated food record, anthropometric measurements (Dual-energy X-ray Absorptiometry) and hematological analysis (iron and vitamin D). Mean BMI was 19.7 ± 2.4 kg/m2 and percentage body fat, 23.5 ± 4.1%. The majority (89.4%) of dancers had a healthy weight (5th-85th percentile) using BMI-for-age growth charts. Food records showed a mean energy intake of 8097.3 ± 2155.6 kJ/day (48.9% carbohydrate, 16.9% protein, 33.8% fat, 14.0% saturated fat). Mean carbohydrate and protein intakes were 4.8 ± 1.4 and 1.6 ± 0.5 g/kg/day respectively. Over half (54.8%) of dancers consumed less than 5 g carbohydrate/kg/day, and 10 (23.8%) less than 1.2 g protein/kg/day. Over 60% consumed less than the estimated average requirement for calcium, folate, magnesium and selenium. Thirteen (28.3%) dancers had suboptimal iron status (serum ferritin (SF) ballet dancers are at risk for iron deficiency, and possibly inadequate nutrient intakes. PMID:25386731

    Full Text Available During the years passed after the Chernobyl accident we are carrying out monitoring of the radiation situation in the Sough-Western territories of the Bryansk region, contaminated with the long-living radionuclides which includes 137Сs concentration measurements in agricultural and natural foodstuffs, surveys of local populations on the structure and composition of the diet accompanied with 137Сs content measurements in the human body. In the article the obtained data is systematized on the food rations of the adult population of theBryansk region, on food rations dynamics in the first and following years after the accident, which is necessary for the correct estimation of internal exposure doses of the population living on the contaminated territories.

  13. Thyroid gland status among population living around the semipalatinsk nuclear test site

    International Nuclear Information System (INIS)

    From 1949-1962, regions of Kazakstan near the Semipalatinsk Nuclear Test Site (SNTS) were contaminated with high levels of radioactive fallout from atomic bomb tests carried out at the SNTS. The effective-dose is a principal criterion for the evaluation of the effect of radioactive fallout upon population. Thyroid disease prevalence may be ascertained, as a biomarker of radiation exposure and because it is of interest in itself. Some features from three studies of thyroid gland status among population living around SNTS will be reported. The first study is a case review of pathological findings of 7,271 patients from three regions adjacent to the SNTS, who were surgically treated during 1966-96; the second is a thyroid screening study of a cohort of 3000 village residents who were <20 years of age at the time of major fallout events in the Semipalatinsk region; the third is a complex molecular, morphological investigation and some approaches to rehabilitation of patients with thyroid abnormalities. Our first study revealed that there is a significant trend for the proportion of thyroid cancer to increase over time in the Semipalatinsk region of Kazakstan 20-29 years after onset of testing in 1949, which might be related to radiation exposure. There are many ethnic groups in this region. Our research among two main ethnic groups (native Kazakh and European extraction) detected that the initial level of thyroid abnormalities and thyroid cancer was higher among residents of European extraction. The total number of surgical cases increased among both ethnic groups over the years, but the numbers of cases with Hashimoto's thyroiditis and thyroid cancer increased dramatically among ethnic Kazakhs. Overall, papillary and follicular cancers predominated, but it should be noted the relatively high percentage of follicular cancers after 1982 in the Semipalatinsk region. The primary screening outcome measure was the prevaleance of thyroid nodules as determined by ultrasound

    This study examined, within the context of the Contingencies of Self-Worth model, state-based associations between self-esteem and body satisfaction using the experience sampling method. One hundred and forty-four adolescent girls (mean age = 14.28 years) completed up to 6 assessments per day for one week using Palm Digital Assistants, in addition to baseline measures of trait body satisfaction and self-esteem. Results showed considerable variation in both state-based constructs within days, and evidence of effects of body satisfaction on self-esteem, but not vice versa. Although these state-based associations were small in size and weakened as the time lag between assessments increased for the sample as a whole, individual differences in the magnitude of these effects were observed and predicted by trait self-esteem and body satisfaction. Collectively, these findings offer support for key tenets of the Contingencies of Self-Worth model. PMID:26356806

    Long-lived plant species are highly valued environmentally, economically, and socially, but can also cause substantial harm as invaders. Realistic demographic predictions can guide management decisions, and are particularly valuable for long-lived species where population response times can be long. Long-lived species are also challenging, given population dynamics can be affected by factors as diverse as herbivory, climate, and dispersal. We developed a matrix model to evaluate the effects of herbivory by a leaf-feeding biological control agent released in Australia against a long-lived invasive shrub (mesquite, Leguminoseae: Prosopis spp.). The stage-structured, density-dependent model used an annual time step and 10 climatically diverse years of field data. Mesquite population demography is sensitive to source-sink dynamics as most seeds are consumed and redistributed spatially by livestock. In addition, individual mesquite plants, because they are long lived, experience natural climate variation that cycles over decadal scales, as well as anthropogenic climate change. The model therefore explicitly considered the effects of both net dispersal and climate variation. Herbivory strongly regulated mesquite populations through reduced growth and fertility, but additional mortality of older plants will be required to reach management goals within a reasonable time frame. Growth and survival of seeds and seedlings were correlated with daily soil moisture. As a result, population dynamics were sensitive to rainfall scenario, but population response times were typically slow (20-800 years to reach equilibrium or extinction) due to adult longevity. Equilibrium population densities were expected to remain 5% higher, and be more dynamic, if historical multi-decadal climate patterns persist, the effect being dampened by herbivory suppressing seed production irrespective of preceding rainfall. Dense infestations were unlikely to form under a drier climate, and required net

    2016-06-01

    This is a retrospective review of pedicle screw placement in adolescent idiopathic scoliosis (AIS) patients under 18 years of age who underwent robot-assisted corrective surgery. Our primary objective was to characterize the accuracy of pedicle screw placement with evaluation by computed tomography (CT) after robot-assisted surgery in AIS patients. Screw malposition is the most frequent complication of pedicle screw placement and is more frequent in AIS. Given the potential for serious complications, the need for improved accuracy of screw placement has spurred multiple innovations including robot-assisted guidance devices. No studies to date have evaluated this robot-assisted technique using CT exclusively within the AIS population. Fifty patients were included in the study. All operative procedures were performed at a single institution by a single pediatric orthopedic surgeon. We evaluated the grade of screw breach, the direction of screw breach, and the positioning of the patient for preoperative scan (supine versus prone). Of 662 screws evaluated, 48 screws (7.2 %) demonstrated a breach of greater than 2 mm. With preoperative prone position CT scanning, only 2.4 % of screws were found to have this degree of breach. Medial malposition was found in 3 % of screws, a rate which decreased to 0 % with preoperative prone position scanning. Based on our results, we conclude that the proper use of image-guided robot-assisted surgery can improve the accuracy and safety of thoracic pedicle screw placement in patients with adolescent idiopathic scoliosis. This is the first study to evaluate the accuracy of pedicle screw placement using CT assessment in robot-assisted surgical correction of patients with AIS. In our study, the robot-assisted screw misplacement rate was lower than similarly constructed studies evaluating conventional (non-robot-assisted) procedures. If patients are preoperatively scanned in the prone position, the misplacement rate is further

    Full Text Available Abstract Background Harmful social conditions in early life might predispose individuals to dental status which in turn may impact on adolescents' quality of life. Aims To estimate the prevalence of oral health impacts among 12 yr-old Brazilian adolescents (n = 359 and its association with life course socioeconomic variables, dental status and dental services utilization in a population-based birth cohort in Southern Brazil. Methods Exploratory variables were collected at birth, at 6 and 12 yr of age. The Oral Impacts on Daily Performances index (OIDP was collected in adolescence and it was analyzed as a ranked outcome (OIDP from 0 to 9. Unadjusted and adjusted multivariable Poisson regression with robust variance was performed guided by a theoretical determination model. Results The response rate was of 94.4% (n = 339. The prevalence of OIDP = 1 was 30.1% (CI95%25.2;35.0 and OIDP ≥ 2 was 28.0% (CI95%23.2;32.8. The most common daily activity affected was eating (44.8%, follow by cleaning the mouth and smiling (15.6%, and 15.0%, respectively. In the final model mother schooling and mother employment status in early cohort participant's life were associated with OIDP in adolescence. As higher untreated dental caries at age 6 and 12 years, and the presence of dental pain, gingival bleeding and incisal crowing in adolescence as higher the OIDP score. On the other hand, dental fluorosis was associated with low OIDP score. Conclusion Our findings highlight the importance of adolescent's early life social environmental as mother schooling and mother employment status and the early and later dental status on the adolescent's quality of life regardless family income and use of dental services.

    International Nuclear Information System (INIS)

    The measurement of ionization distribution caused by the cosmic ray ionizing components in the air, the survey of population distribution in geography and the investigation of total passengers taking air liners at the mainland of China have been completed. By taking the data from the census of the year 1986 and the population distribution of the mainland, considering the cosmic ray distribution with the height and referring the distribution of neutron flux density in cosmic ray, the population-weighted mean annual effective dose equivalent, which is obtained from 2017 counties and 353 cities, for inhabitants living in every provinces and municipalities directly under Central Government has been calculated. The collective dose equivalent produced by the external exposure of cosmic ray is also estimated when people are taking air liners. The results which are effected by the population distribution show that the annual effective dose equivalant received by the population of China from the cosmic ray is 28% lower than the population of the world. The most of Chinese people are living at the north hemisphere area having lower elevation and geomagnetic latitude, and 53.6% among them is in the area of elevation below 100 m and 91% is in the area of geomagnetic latitude below 30 deg N

    Adherence to antiretroviral therapy (ART) is crucial for thwarting HIV disease progression and reducing secondary HIV transmission, yet youth living with HIV (YLH) struggle with adherence. The highest rates of new HIV infections in the United States occur in young African American men. A sample of 387 HIV-positive young African American males on ART was selected from a cross-sectional assessment of (YLH) receiving medical care within the Adolescent Trials Network for HIV/AIDS Interventions (ATN) from 2010 to 2012 (12-24 years old, median 22.00, SD 2.08). Participants completed self-reported adherence, demographic, health, and psychosocial measures. Sixty-two percent self-reported 100% ART adherence. Optimal data analysis identified frequency of cannabis use during the past 3 months as the strongest independent predictor of adherence, yielding moderate effect strength sensitivity (ESS) = 27.1, p cannabis use, 72% reported full adherence; in contrast, only 45% of participants who used cannabis frequently reported full adherence. Classification tree analysis (CTA) was utilized to improve classification accuracy and to identify the pathways of ART adherence and nonadherence. The CTA model evidenced a 38% improvement above chance for correctly classifying participants as ART adherent or nonadherent. Participants most likely to be adherent were those with low psychological distress and minimal alcohol use (82% were adherent). Participants least likely to be adherent were those with higher psychological distress and engaged in weekly cannabis use (69% were nonadherent). Findings suggest multiple profiles of ART adherence for young African American males living with HIV and argue for targeted psychosocial interventions. PMID:27410496

    This research aims to investigate the rate and nature of anxiety symptoms in a group of children and adolescents living with chronic illnesses in Jordan, and their relation to social desirability in a cultural sample not previously researched. Using the Revised Children's Manifest Anxiety Scale (R-CMAS), anxiety and social desirability data were obtained from 114 children diagnosed with chronic illnesses and 162 healthy control participants. Based on children's self-report, participants were categorized according to their adaptive style paradigm as either high anxious, low anxious, or repressor. It was proposed that children who score high on social desirability and low on anxiety are repressors. The prevalence of these categories was compared across the two groups. Anxiety was reported in 9.64 percent of the chronic illnesses and 12.34 percent of the healthy peers. Using the data obtained in the present study, the rate and nature of anxiety in children with chronic illnesses were lower for children in Jordan when compared to previous studies. However, social desirability values were similar to those established in Western societies suggesting a significantly higher percentage of children identified as repressors in children with long-term illnesses. These results supported the hypothesis regarding the relationship between social desirability and expressed anxiety symptoms. PMID:23242812

    Approximately 42 million adolescents aged 10-19 years, representing 13% of the population, resided in the United States in 2014 (1). Adolescence is characterized by rapid and profound physical, intellectual, emotional, and psychological changes (2), as well as development of healthy or risky behaviors that can last a lifetime. Parents have strong influence on their adolescent children's lives, and family-based programs can help parents support healthy adolescent development. Because schools are natural learning environments, implementing and improving school-based policies and programs are strategic ways to reinforce healthy behaviors and educate adolescents about reducing risky behaviors. Health care during adolescence should be tailored to meet the changing developmental needs of the adolescent while providing welcoming, safe, and confidential care. Parents, educators, care providers, public health officials, and communities should collaborate in fostering healthy environments for all adolescents, now and into the future. PMID:27491062

    Full Text Available Objective. The present study was designed to investigate the prevalence of different combinations of the metabolic syndrome (MetS risk factors among a nationally representative sample of adolescents in the Middle East and North Africa (MENA. Methods. The study sample, obtained as part of the third study of the school-based surveillance system entitled CASPIAN III, was representative of the Iranian adolescent population aged from 10 to 18 years. The prevalence of different components of MetS was studied and their discriminative value was assessed by receiver operating characteristic (ROC curve analysis. Results. The study participants consisted of 5738 students (2875 girls with mean age of 14.7±2.4 years living in 23 provinces in Iran; 17.4% of participants were underweight and 17.7% were overweight or obese. Based on the criteria of the International Diabetes Federation for the adolescent age group, 24.2% of participants had one risk factor, 8.0% had two, 2.1% had three, and 0.3% had all the four components of MetS. Low HDL-C was the most common component (43.2% among the overweight/obese versus 34.9% of the normal-weight participants, whereas high blood pressure was the least common component. The prevalence of MetS was 15.4% in the overweight/obese participants, the corresponding figure was 1.8% for the normal-weight students, and 2.5% in the whole population studied. Overweight/obese subjects had a 9.68 increased odds of (95% CI: 6.65–14.09 the MetS compared to their normal-weight counterparts. For all the three risk factors, AUC ranged between 0.84 and 0.88, 0.83 and 0.87, and 0.86 and 0.89 in waist circumference, abdominal obesity, and BMI for boys and between 0.78 and 0.97, 0.67 and 0.93, and 0.82 and 0.96 for girls, respectively. Conclusion. The findings from this study provide alarming evidence-based data on the considerable prevalence of obesity, MetS, and CVD risk factors in the adolescent age group. These results are confirmatory

    Tularemia which is a zoonotic infection, caused by Francisella tularensis, has become a re-emerging disease in Turkey. Infection is often transmitted to human by handling animal tissues and products, but it is also possible to acquire the disease from contaminated water or food. Recently several cases and epidemics of tularemia have been reported in the northwest areas of Turkey, particularly in Marmara and West Black Sea regions. Erzurum is a city in Eastern Anatolia Region, Turkey and animal husbandry is the main agricultural activity in that area. However, neither tularemia cases were reported from this province nor seroprevalence studies were performed. In this study we aimed to determine F.tularensis antibody seropositivity in the risky population living at both rural and urban area of Erzurum. Blood samples from 240 volunteer subjects (134 male with mean age: 36.2, age range: 17-75 years and 106 female with mean age: 39.1, age range: 16-77 years) whose occupations were farming and animal husbandry, were included in the study. Serum samples were screened for the presence of F.tularensis antibodies by slide agglutination method (BD, USA) and Serazym ELISA kit (anti-F.tularensis IgG/IgA/IgM, Seramun, Germany). The positive samples with those tests were also retested by microagglutination test (MAT) in National Tularemia Reference Laboratory of Refik Saydam Hygiene Center, using antigen prepared in the same laboratory from the local strain. The serum samples were also searched for the presence of Brucella and Salmonella antibodies in terms of cross-reactivity. Seropositivity was detected in 71 (29.6%) out of 240 subjects by slide agglutination test (SAT), whereas only 5 (2.1%) gave positive result for total antibody by ELISA. Twenty-five of the 71 SAT positive samples yielded F.tularensis antibodies by MAT, of which 21 were between 1/20-1/40 and four were between 1/80-1/160 titers. However, all of the MAT positive samples (n= 25) were found reactive in Brucella

  6. Epidemiology of cancer in population living in contaminated territories of Ukraine, Belarus, Russia after the Chernobyl accident

    International Nuclear Information System (INIS)

    Statistical data of oncology service of Ukraine, Belarus, and Russia on the number of new patients with cancer and leukemia in 1980-1994 in 12 regions adjacent to the Chernobyl NPP are generalized. Spatio-temporal for incidence of malignant diseases in population are developed. The analysis of possible connections between the effective dose and incidence of cancer in population living in the area contaminated by radionuclides is performed. Spatio-temporal models for the incidence of cancer including leukemias and lymphomas are found to be the same in the pre- and post-accidental periods. Nine years after the Chernobyl accident there are no scientific evidence for the excess of incidence of malignant tumors, except thyroid cancer, attributed to radiation factor, even in the most contaminated areas. Appearance of previously unregistered thyroid cancer cases in children living in the territory, where considerable amount of radioactive iodine was deposited, can indicate stochastic radiation effects in thyroid

    The consumption of fish is usually considered the main route of contamination of mercury in humans. In a climate change scenario implying ocean acidification, mercury methylation is expected to increase leading to bioaccumulation increments in the food chain, affecting mainly coastal populations. In this study, mercury accumulation and fish consumption was evaluated considering mercury concentrations in human scalp hair in relation to fish consumption habits in adolescents (16 to 21 years ...

    Background Enuresis (9% at age 9.5) negatively affects children’s psychosocial status. Clinically-diagnosed enuresis (2% at the age) is associated with hyperactivity-inattention, and common neural bases have been postulated to underlie this association. It is, however, unclear whether this association is applicable to enuresis overall among the general population of early adolescents when considered comorbid behavioral problems. We aimed to examine whether enuresis correlates with hyperactivity-inattention after controlling for the effects of other behavioral problems. Methods Participants were 4,478 children (mean age 10.2 ± 0.3 years old) and their parents from the Tokyo Early Adolescence Survey (T-EAS), a population-representative cross-sectional study conducted in Tokyo, Japan conducted from 2012 to 2015. Children’s enuresis and behavioral problems, including hyperactivity-inattention (as measured by the Strength and Difficulties Questionnaire), were examined using parent-reporting questionnaires. Multivariate linear regression was used to explore whether enuresis predicts hyperactivity-inattention. Results The hyperactivity-inattention score was significantly higher in the enuretic group than the non-enuretic group (enuretic: M (SD) = 3.8 (2.3), non-enuretic: M (SD) = 3.0 (2.1), Hedge’s g = 0.39, p < .001). This association remained significant even after controlling for other behavioral problems and including sex, age, intelligence quotient (IQ), low birth weight and parents’ education (β = .054 [95% CI: .028–.080], p < .001). Conclusions Enuresis was independently associated with hyperactivity-inattention in early adolescents among general population even when other behavioral problems were considered. These results suggest that, as with clinically-diagnosed cases, enuresis may predict need for screening and psychosocial support for hyperactivity-inattention. PMID:27414399

    French Guiana, a French overseas department in South America, has been classified epidemic for HIV. This territory is consisting of a very young population with almost 45% of them being younger than 20 years of age. Delaying the onset of first sexual intercourse (SI) is one of the major objectives to fight HIV infection in adolescents. The objective of this study is to identify the age of first SI and the risk factors of early onset. A behavioural surveillance survey among students living on the coastline and alongside the Maroni River was conducted in 2011/2012. A total of 1603 students filled out the survey. While 60% had already SI, the mean age of first intercourse was 12.1 years for boys and 13.9 years for girls. Accordingly, over 90% had a premature onset of SI. Risk factors are age, male gender, living alongside the Maroni River, another language than the French being mother tongue, not being religious, alcohol and cannabis consumption and a bad attitude towards condom use. Risk factors for girls are an older first sexual partner, having more than three lifetime sexual partners and condom rupture. Evidence-based implementation with respect of local and socio-demographic aspects is necessary to improve youths' appreciation of SI and related risk of sexual transmitted diseases. PMID:25782704

    Mercury and other trace elements were measured in hair samples collected from subjects of a population group having an average annual fish consumption significantly higher than that for the italian population. The determination of the trace elements was carried out by instrumental neutron activation analysis. The results show that the levels of trace elements in the hair of this population group are higher than those reported for italian population. In particular the high values of mercury concentration found samples indicate that some subjects may exceed the mercury PTWI (Provisional Tolerable Weekly Intake)

    Theory holds that income inequality may harm adolescent mental health by reducing social capital within neighborhood communities. However, research on this topic has been very limited. We use multilevel data on 102 public schools and 5958 adolescents in Iceland (15 and 16 years old) to examine whether income inequality within neighborhoods is associated with emotional distress in adolescents. Moreover, we test whether indicators of social capital, including social trust and embeddedness in neighborhood social networks, mediate this contextual effect. The findings show that neighborhood income inequality positively influences emotional distress of individual adolescents, net of their personal household situations and social relations. However, although the indicators of social capital negatively influence emotional distress, they do not mediate the contextual effect of neighborhood income inequality. The study illustrates the role of economic disparities in adolescent mental health, but calls for more research on the underlying social and social-psychological mechanisms. PMID:27337213

    Health-related quality of life (HRQOL) of children and adolescents with chronic health conditions is a multifactorial concept that combines a child's perception and adaptation to physical, social, emotional, and school environments regardless of particular medical diagnosis. Children with chronic kidney disease (CKD) experience non-kidney specific co-morbidities, including depression, body image alterations, and sleep disturbance, that impair their daily lives. This article reviews the pediatric nephrology literature to highlight the evidence identifying these riskr to HRQOL and suggesting ways in which nurses in both nephrology and primary care are poised to identify and modify these risk factors.

    Full Text Available Background. Sleep duration, either short or long, has been associated with diseases such as obesity, type-2 diabetes and cardiovascular diseases. Characterizing the prevalence and patterns of sleep duration at the population-level, especially in resource-constrained settings, will provide informative evidence on a potentially modifiable risk factor. The aim of this study was to explore the patterns of sleep duration in the Peruvian adult and adolescent population, together with its socio-demographic profile. Material and Methods. A total of 12,424 subjects, mean age 35.8 years (SD ±17.7, 50.6% males, were included in the analysis. This is a cross-sectional study, secondary analysis of the Use of Time National Survey conducted in 2010. We used weighted means and proportions to describe sleep duration according to socio-demographic variables (area and region; sex; age; education attainment; asset index; martial and job status. We used Poisson regressions, taking into account the multistage sampling design of the survey, to calculate crude and adjusted prevalence ratios (PR and 95% confidence intervals (95% CI. Main outcomes were short- (<6 h and long-sleep duration (≥ 9 h. Results. On average, Peruvians slept 7.7 h (95% CI [7.4–8.0] on weekdays and 8.0 h (95% CI [7.8–8.1] during weekends. The proportions of short- and long-sleep, during weekdays, were 4.3% (95% CI [2.9%–6.3%] and 22.4% (95% CI [14.9%–32.1%], respectively. Regarding urban and rural areas, a much higher proportion of short-sleep was observed in the former (92.0% vs. 8.0%; both for weekdays and weekends. On the multivariable analysis, compared to regular-sleepers (≥ 6 to <9 h, short-sleepers were twice more likely to be older and to have higher educational status, and 50% more likely to be currently employed. Similarly, relative to regular-sleep, long-sleepers were more likely to have a lower socioeconomic status as per educational attainment. Conclusions. In this

    The external mucus layers of the stony coral Porites astreoides and the soft corals Palythoa sp. and Heteroxenia fuscesens are inhabited by communities of marine heterotrophic bacteria. Population levels of bacteria in coral mucus may be regulated by the self-cleaning behavior of the host. Bacterial populations in coral mucus respond to stresses applied to the host coral by growing to higher population levels in the mucus, indicating that these are populations of viable organisms closely attuned to host metabolism. Members of these microbial populations utilize the mucus compounds and may play a role in processing coral mucus for reef detritus feeders. One such species, Vibrio alginolyticus, grows rapidly on Heteroxenia mucus, is attracted to dissolved mucus, and possesses a mechanism to maintain itself on the coral surface.

  8. Biochemical polymorphism of Dreyssena polimorpha populations living in a cooler reservoir of an atomic power station

    International Nuclear Information System (INIS)

    Analysis of three Dr.polimorpha populations, residing in a NPP cooling pond, comprising hot and cold parts, from where samples of two populations are taken, is presentes. Samples of the third population are taken from the river to the basin of which the cooling pond belongs. It is shown that the studied Dr. polimorpha population differentiation by LAP-2 and EST-D loci is linked with the temperature factor effect. Continuous (over 10 years) effect of increased temperature has led to a sufficient shift of allelic frequencies by the loci indicated, while the radiation factor effect during 2 years has not led to the population effects revealed. Populatiion differentiation is observed by the loci, demonstrating a divergence with theoretical frequenncies according to Hardy-Weiberg in all the investigated localities

  11. Gene expression and physiological changes of different populations of the long-lived bivalve Arctica islandica under low oxygen conditions.

    Directory of Open Access Journals (Sweden)

    Eva E R Philipp

    Full Text Available The bivalve Arctica islandica is extremely long lived (>400 years and can tolerate long periods of hypoxia and anoxia. European populations differ in maximum life spans (MLSP from 40 years in the Baltic to >400 years around Iceland. Characteristic behavior of A. islandica involves phases of metabolic rate depression (MRD during which the animals burry into the sediment for several days. During these phases the shell water oxygen concentrations reaches hypoxic to anoxic levels, which possibly support the long life span of some populations. We investigated gene regulation in A. islandica from a long-lived (MLSP 150 years German Bight population and the short-lived Baltic Sea population, experimentally exposed to different oxygen levels. A new A. islandica transcriptome enabled the identification of genes important during hypoxia/anoxia events and, more generally, gene mining for putative stress response and (anti- aging genes. Expression changes of a antioxidant defense: Catalase, Glutathione peroxidase, manganese and copper-zinc Superoxide dismutase; b oxygen sensing and general stress response: Hypoxia inducible factor alpha, Prolyl hydroxylase and Heat-shock protein 70; and c anaerobic capacity: Malate dehydrogenase and Octopine dehydrogenase, related transcripts were investigated. Exposed to low oxygen, German Bight individuals suppressed transcription of all investigated genes, whereas Baltic Sea bivalves enhanced gene transcription under anoxic incubation (0 kPa and, further, decreased these transcription levels again during 6 h of re-oxygenation. Hypoxic and anoxic exposure and subsequent re-oxygenation in Baltic Sea animals did not lead to increased protein oxidation or induction of apoptosis, emphasizing considerable hypoxia/re-oxygenation tolerance in this species. The data suggest that the energy saving effect of MRD may not be an attribute of Baltic Sea A. islandica chronically exposed to high environmental variability (oxygenation

    The purpose of this study was to provide population-based estimates of leisure-time physical activity (LTPA) in Canadians diagnosed with Crohn disease (CD) or ulcerative colitis (UC). Data were derived from the Canadian Community Health Survey Cycle 3.1 (2005). Those diagnosed with CD (n = 474; 61.60% female) or UC (n = 637; 65.10% female) were compared with those not reporting CD/UC (n = 113,685; 53.60% female). The most prevalent forms of LTPA reported were walking and gardening/yard work. Individuals with CD were more likely to be classified as "inactive" (OR = 1.34; 95% CI [1.12, 1.61]) and less likely to be "active" (OR = 0.69; 95% CI [0.55, 0.87]) than those not reporting CD/UC. These trends were mirrored for those living with UC, although statistical significance was not attained. Despite claims advocating the benefits of LTPA for ameliorating complications associated with CD/UC, prevalence estimates from a population-based sample of Canadians living with CD/UC suggest that the majority do not meet current public health guidelines. Results offer benchmarks for prevalence of LTPA in those diagnosed with CD/UC. Findings suggest that many living with this condition will not benefit from the protective role of LTPA on complications associated with CD/UC. PMID:21814062

    Population explosion is considered to be one of the most crucial problems in the world. However, in Japan, the opposite problem: population decline has become serious now. Japanese population is estimated to decrease by twenty millions in 2040. This negative situation will cause to increase areas where many residents cannot make a daily living all over Japan because many convenience living facilities such as supermarkets, convenience stores and drugstores will be difficult to maintain their market area population due to future population decline. In our research, we used point data of convenience living facilities developed by address geocoding of digital telephone directory and point data of future population projection developed by distribution of Japanese official population projection data proportionally among the building volume of digital residential map, which can monitor building volumes all over Japan. In conclusion, we estimated that various convenience living facilities in Japan will shrink and close by population decline in near future. In particular, it is cleared that approximately 14.7% of supermarkets will be possible to withdraw all over Japan by 2040. In addition, it is cleared that over 40% of supermarkets in some countryside prefectures will be possible to withdraw by 2040. Thus, we estimated future distributions of convenience living facilities that cannot maintain their market area population due to future population decline. Moreover, we estimated the number of people that they will become inconvenience in buying fresh foods.

  14. Population genetics at three spatial scales of a rare sponge living in fragmented habitats

    Directory of Open Access Journals (Sweden)

    Uriz Maria J

    2010-01-01

    Full Text Available Abstract Background Rare species have seldom been studied in marine habitats, mainly because it is difficult to formally assess the status of rare species, especially in patchy benthic organisms, for which samplings are often assumed to be incomplete and, thus, inappropriate for establishing the real abundance of the species. However, many marine benthic invertebrates can be considered rare, due to the fragmentation and rarity of suitable habitats. Consequently, studies on the genetic connectivity of rare species in fragmented habitats are basic for assessing their risk of extinction, especially in the context of increased habitat fragmentation by human activities. Sponges are suitable models for studying the intra- and inter-population genetic variation of rare invertebrates, as they produce lecitotrophic larvae and are often found in fragmented habitats. Results We investigated the genetic structure of a Mediterranean sponge, Scopalina lophyropoda (Schmidt, using the allelic size variation of seven specific microsatellite loci. The species can be classified as "rare" because of its strict habitat requirements, the low number of individuals per population, and the relatively small size of its distribution range. It also presents a strong patchy distribution, philopatric larval dispersal, and both sexual and asexual reproduction. Classical genetic-variance-based methods (AMOVA and differentiation statistics revealed that the genetic diversity of S. lophyropoda was structured at the three spatial scales studied: within populations, between populations of a geographic region, and between isolated geographic regions, although some stochastic gene flow might occur among populations within a region. The genetic structure followed an isolation-by-distance pattern according to the Mantel test. However, despite philopatric larval dispersal and fission events in the species, no single population showed inbreeding, and the contribution of clonality to the

  16. The decision-making process in dealing with populations living in areas contaminated by the Chernobyl accident. The ETHOS project

    International Nuclear Information System (INIS)

    Experience from the Chernobyl accident revealed strong disturbance in social life and stress phenomenon in the population living in the contaminated territories. The ETHOS project (founded by the radiation protection research programme of the European Commission-DG XII) has initiated an alternative approach of the rehabilitation of living conditions in the contaminated territories of the CIS in the post-accident context of Chernobyl. This project started at the beginning of 1996 and is implemented in the Republic of Belarus. Its main goal is to create the conditions for the inhabitants of contaminated territories to reconstruct their global quality of life. The main features of the methodological approach of the ETHOS project in the village of Olmany in the district of Stolyn (Brest region) since March 1996 are presented, and its implementation and first results are discussed.

  17. Workshop on dosimetry of the population living in the proximity of the Semipalatinsk atomic weapons test site

    International Nuclear Information System (INIS)

    From 1949 nuclear weapons tests were conducted at the Semipalatinsk test site in Kazakhstan. Until the early 1960s many of these tests were conducted either on the ground or above ground. The radioactive fission products released in these explosions were deposited at substantial distances from the test site (Polygon) and may have exposed populations living in Semipalatinsk Region and the Altai region of the Russian Federation. A much larger number of tests has been conducted underground with only limited release of radioactive material to the atmosphere. A number of estimates have been made, by Kazak and Russian scientists, of the radiation doses to the populations living in the areas surrounding the test site but few of these are based on actual measurements of radioactivity on the ground and in vegetation. More recently, other international groups have predicted historical doses based on literature data and/or contemporary soil caesium measurements while others have used a variety of modern measurement techniques such as thermoluminescence in ceramic objects, EPR in teeth, and other types of biological dosimetry. A workshop addressing these issues was organised by the National Cancer Institute (NCI, USA), World Health Organisation (WHO) and Radiation and Nuclear Safety Authority (STUK, Finland) in May 2001. The purpose of the workshop was to review all the available dosimetric data in order to make an assessment of the radiological impact and the associated uncertainties, on populations in the vicinity and identify populations that might be useful subjects of epidemiological study. Particular emphasis was given to assessing doses to members of the public, i.e., off-site populations. (orig.)

    We evaluated a study setting for assessment of the long-term vaccine efficacy (VE) of human papillomavirus (HPV) virus-like-particle (VLP) vaccine against cervical carcinoma. A total of 22,412 16- to 17-year old adolescent women from seven cities in Finland were invited by letter to participate in a phase III study of a quadrivalent HPV (types 6, 11, 16, 18) VLP vaccine, between September 2002 and March 2003. A total of 30,947 18-year old women were invited to participate as unvaccinated controls. These women were asked about their willingness to participate in an HPV vaccination trial and to fill a health questionnaire. These three population-based cohorts of adolescent women, including women vaccinated with HPV vaccine or placebo vaccine and unvaccinated control women, are systematically followed over time. The study cohort database will be linked with the Finnish Cancer Registry using cervical carcinoma in situ (CIS) and invasive cervical carcinoma (ICC) as endpoints. Assuming that the cumulative incidence of CIS and ICC over 15 years is 0.45%, and that there is no loss to follow-up, and power of 80%, the determination of 70% total VE will require 3357 HPV vaccine recipients, 3357 placebo vaccine recipients, and 6714 unvaccinated controls. At the baseline, 2632 (12%) of the invited adolescents volunteered to the phase III vaccination trial, and 6790 (22%) responded to the questionnaire study. During a recruitment period of 10 months, 874 HPV vaccine recipients, 875 placebo recipients and 1919 unvaccinated controls were enrolled. Population-based enrollment of large cohorts of vaccinated and unvaccinated adolescents for passive registry-based follow-up with cervical carcinoma as the end-point is feasible and currently going on in Finland.

    This study tested the model of suicidal ideation, incorporating family and personal factors to predict suicidal ideation with hopelessness as a mediating factor in the Hong Kong sample, to a sample in Shanghai. Using MGSEM, the study aims to investigate the personal correlates and the family correlates of suicidal ideation in Hong Kong and Shanghai adolescents. We integrated the family ecological and diathesis-stress-hopelessness models of suicidal ideation in connecting the correlates. A cross-sectional design was used. The full model achieved metric invariance and partial path-loading invariance. Family functioning and social problem solving negatively predicted hopelessness or suicidal ideation in both the Hong Kong and Shanghai adolescents. The results supported an integrative approach in facilitating parent-adolescent communication and strengthening family functioning, and reducing the use of negative social problem-solving styles in adolescent suicide prevention.

    This is a theoretical reflection, based on Michel Maffesoli's Comprehensive Sociology, which is concerned with the health care of adolescents in contemporary everyday life, and particularly with the phenomenon of urban tribes. These are understood as groups of people who have emotional ties, building a bond of sociality towards a common goal. This study focuses on the importance to take into account the lifestyle of adolescents and aims to raise awareness among health professionals about such issues, seeking for strategies tuned with reality and care needs in order to promote health, devising ways to improve caring, rethinking health policies for adolescents in contemporary society.

    Full Text Available Abstract Background In 1988 the World Health Assembly adopted the goal to eradicate poliomyelitis by routine immunization using Oral Polio Vaccine (OPV. On 21 June 2002 the WHO European Region was declared polio-free. In 2008 poliomyelitis is still endemic in 4 countries (Nigeria, India, Pakistan, and Afghanistan, where 1201 new cases were registered in 2007; 107 sporadic cases were also notified in countries where poliovirus is not endemic. The aim of this work was to verify the level of antipoliomyelitis immunity status in children and adolescents in the Apulia region (south of Italy, which may be considered a border region due to its position. Methods 704 blood specimens from a convenience sample were collected in six laboratories. The age of subjects enrolled was 0–15 years. The immunity against poliomyelitis was evaluated by neutralizing antibody titration in tissue culture microplates. Results Seropositivity (neutralising antibodies titre ≥ 8 for polioviruses 1, 2 and 3 was detected in 100%, 99.8% and 99.4% of collected sera. Antibody titres were not lower in subjects who received either four doses of inactivated polio vaccine (IPV or a sequential schedule consisting of two doses of IPV and two of oral polio vaccine than in subjects who received four doses of OPV. Conclusion These results confirmed current data of vaccine coverage for poliomyelitis: during the last ten years in Apulia, the coverage in 24 months old children was more than 90%. The high level of immunization found confirms the effectiveness both of the sequential schedule IPV-OPV and of the schedule all-IPV. Apulia region has to face daily arrivals of refugees and remains subject to the risk of the importation of poliovirus from endemic areas. Surveys aimed at determining anti-polio immunity in subpopulations as well as in the general population should be carried out.

    A cross-sectional study was carried out in the low income population of certain areas of the city of Tijuana, Mexico. Data collected showed that these suburban areas are inhabited by people from rural areas of Mexico, with minimum education, that basically work at the "maquiladoras". General hygienic conditions were poor and the services insufficient. The prevalence of diarrheas among the population was extremely high in the two weeks previous to the study, being highest for children less than one year old, in which the proportion with at least one episode of diarrhea was 47 per cent.

  7. Cadmium exposure pathways in a population living near a battery plant

    International Nuclear Information System (INIS)

    Objectives: The objectives of the present study were to assess the relative impact of different pathways of environmental cadmium (Cd) exposure and to evaluate the contribution from locally produced vegetables and root crops to the total dietary intake of Cd. Methods: Cadmium in urine was determined for 492 individuals living near a closed down battery factory in Sweden. For each individual we created an environmental exposure-index based on Cd emissions to ambient air and number of years living at various distances from the plant. This information as well as dietary data were collected via questionnaires. Samples of soil, carrots and/or potatoes were collected from 37 gardens and analysed for Cd concentration. Results: Eating homegrown vegetables/potatoes, environmental Cd-exposure-index, female gender, age above 30 years and smoking more than one pack of cigarettes daily for at least 10 years were found to be significantly associated with increased urine concentrations of Cd (UCd > 1.0 nmol/mmol creatinine). We found a statistically significant relation between Cd in urine and environmental Cd-exposure-index in persons eating homegrown vegetables/potatoes regularly. Cd concentrations in homegrown carrots, potatoes and in garden soil were highest in the area closest to the factory. Daily consumption of potatoes and vegetables cultivated in the vicinity of the closed battery factory was estimated to increase Cd intake by 18-38%. Conclusion: The present study shows that consumption of locally grown vegetables and root crops was an important exposure pathway, in subjects living near a nickel-cadmium battery plant, whereas direct exposure via ambient air was less important

    Long-lived population storage in optically pumped levels of rare-earth ions doped into solids, referred to as persistent spectral hole burning, is of significant fundamental and technological interest. However, the demonstration of deep and persistent holes in rare-earth ion doped amorphous hosts, e.g., glasses, has remained an open challenge for many decades—a fact that motivates our work towards a better understanding of the interaction between impurities and vibrational modes in glasses. Here we report the observation and detailed characterization of such holes in an erbium-doped silica glass fiber cooled to below 1 K. We demonstrate population storage in electronic Zeeman sublevels of the erbium ground state with lifetimes up to 30 seconds and 80% spin polarization. In addition to its fundamental aspect, our investigation reveals a potential technological application of rare-earth ion doped amorphous materials, including at telecommunication wavelength.

    2008-08-01

    Full Text Available Abstract Background Some populations targeted in survey research can be hard to reach, either because of lack of contact information, or non-existent databases to inform sampling. Here, we present a methodological "case-report" of the yield of a multi-step survey study assessing views on health care among American emigres to Canada, a hard-to-reach population. Methods To sample this hard-to-reach population, we held a live media conference, supplemented by a nation-wide media release announcing the study. We prepared an 'op-ed' piece describing the study and how to participate. We paid for advertisements in 6 newspapers. We sent the survey information to targeted organizations. And lastly, we asked those who completed the web survey to send the information to others. We use descriptive statistics to document the method's yield. Results The combined media strategies led to 4 television news interviews, 10 newspaper stories, 1 editorial and 2 radio interviews. 458 unique individuals accessed the on-line survey, among whom 310 eligible subjects provided responses to the key study questions. Fifty-six percent reported that they became aware of the survey via media outlets, 26% by word of mouth, and 9% through both the media and word of mouth. Conclusion Our multi-step communication method yielded a sufficient sample of Americans living in Canada. This combination of paid and unpaid media exposure can be considered by others as a unique methodological approach to identifying and sampling hard-to-reach populations.

    2016-01-01

    The Western Australian (WA) ‘LiveLighter’ (LL) mass media campaign ran during June–August and September–October 2012. The principal campaign ad graphically depicts visceral fat of an overweight individual (‘why’ change message), whereas supporting ads demonstrate simple changes to increase activity and eat healthier (‘how’ to change message). Cross-sectional surveys among population samples aged 25–49 were undertaken pre-campaign (N = 2012) and following the two media waves (N = 2005 and N = 2009) in the intervention (WA) and comparison state (Victoria) to estimate the population impact of LL. Campaign awareness was 54% after the first media wave and overweight adults were more likely to recall LL and perceive it as personally relevant. Recall was also higher among parents, but equal between socio-economic groups. The ‘why’ message about health-harms of overweight rated higher than ‘how’ messages about lifestyle change, on perceived message effectiveness which is predictive of health-related intention and behaviour change. State-by-time interactions showed population-level increases in self-referent thoughts about the health-harms of overweight (P < 0.05) and physical activity intentions (P < 0.05). Endorsement of stereotypes of overweight individuals did not increase after LL aired. LL was associated with some population-level improvements in proximal and intermediate markers of campaign impact. However, sustained campaign activity will be needed to impact behaviour.

    Social networking sites (SNSs) have gained considerable popularity among youth in recent years; however, there is a noticeable paucity of research examining the association between the use of these web-based platforms and cyberbullying victimization at the population level. This study examines the association between the use of SNSs and cyberbullying victimization using a large-scale survey of Canadian middle and high school students. Data on 5,329 students aged 11-20 years were derived from the 2013 Ontario Student Drug Use and Health Survey. Logistic regression was used to examine the relationship between the use of SNSs and cyberbullying victimization while adjusting for covariates. Overall, 19 percent of adolescents were cyberbullied in the past 12 months. Adolescents who were female, younger, of lower socioeconomic status, and who used alcohol or tobacco were at greater odds of being cyberbullied. The use of SNSs was associated with an increased risk of cyberbullying victimization in a dose-response manner (p-trend <0.001). Gender was not a significant moderator of the association between use of SNSs and being cyberbullied. Results from this study underscore the need for raising awareness and educating adolescents on effective strategies to prevent cyberbullying victimization. PMID:26539738

    The aim of this paper was to collect evidence for the effects of contaminants on biota in a highly dynamic river Rhine floodplain. To this purpose we reviewed the results of circa 10 studies performed in this floodplain. The floodplain was contaminated with elevated levels of cadmium, copper, PAHs, and PCBs and high levels of zinc which were at some sites above legislative values. The results showed that the present contaminants were accumulated by the floodplain inhabiting organisms, but meanwhile population and community effects were ambiguous. Only for the mayfly Ephoron virgo clear effects were detected at the level of the single floodplain. The absence of clear population and community effects is puzzling since at lower contaminant concentrations adverse effects were detected in other environments. Factors that may mask toxic effects include flooding and food quality and quantity. We conclude that given the site specific conditions, being an open, eutrophic system with a highly dynamic flooding pattern, assessment of the contribution of toxicants to observed population density or biomass and community composition requires 1] an increase in number of replicates; 2] a larger scale of investigation and 3] comparison to stable systems with comparable contamination levels.

    Full Text Available The aim of this study was to present the general situation of populations of European post-communist countries 25 years after the collapse of communism in Europe. The study consists of two parts. The first one briefly discusses the processes that led to a significant diversification in the social, economic and political situations of the populations of the studied countries. In the second part the diversity of this situation is shown (using: the Legatum Prosperity Index, the Social Progress Index, and the Human Development Index. It was found that the best situations exist in the countries which quickly and effectively implemented reforms, and whether they were independent states, or parts of larger states, under communism is of secondary importance. It is symptomatic that these are countries situated in the north-western part of the area under consideration, which corresponds to the current situation in the EU-15, where the countries located in the south (the so-called PIGS have poor economic and partly social situations than those in the north. Furthermore, it was found that the situation with the population of Russia is worse than in many countries which were previously under the occupation of the USSR or were dependent on the authorities in Moscow.

    Full Text Available Background. Longitudinal investigations into the origins of adult essential hypertension have found elevated blood pressure in children to accurately track into adulthood, however the direct causes of essential hypertension in adolescence and adulthood remains unclear. Methods. We revisited 152 Peruvian adolescents from a birth cohort tracked from 0 to 30 months of age, and evaluated growth via monthly anthropometric measurements between 1995 and 1998, and obtained anthropometric and blood pressure measurements 11–14 years later. We used multivariable regression models to study the effects of infantile and childhood growth trends on blood pressure and central obesity in early adolescence. Results. In regression models adjusted for interim changes in weight and height, each 0.1 SD increase in weight for length from 0 to 5 months of age, and 1 SD increase from 6 to 30 months of age, was associated with decreased adolescent systolic blood pressure by 1.3 mm Hg (95% CI −2.4 to −0.1 and 2.5 mm Hg (95% CI −4.9 to 0.0, and decreased waist circumference by 0.6 (95% CI −1.1 to 0.0 and 1.2 cm (95% CI −2.3 to −0.1, respectively. Growth in infancy and early childhood was not significantly associated with adolescent waist-to-hip ratio. Conclusions. Rapid compensatory growth in early life has been posited to increase the risk of long-term cardiovascular morbidities such that nutritional interventions may do more harm than good. However, we found increased weight growth during infancy and early childhood to be associated with decreased systolic blood pressure and central adiposity in adolescence.

  4. Adolescent fertility: worldwide concerns.

    Senderowitz, J; Paxman, J M

    1985-04-01

    There is growing concern over the adverse health, social, economic, and demographic effects of adolescent fertility. Morbidity and mortality rates ar significantly higher for teenage mothers and their infants, and early initiation of childbearing generally means truncated education, lower future family income, and larger completed family size. Adolescent fertility rates, which largely reflect marriage patterns, range from 4/1000 in Mauritania; in sub-Saharan Africa, virtually all rates are over 100. In most countries, adolescent fertility rates are declining due to rising age at marriage, increased educational and economic opportunities for young women, changes in social customs, increased use of contraception, and access to abortion. However, even if fertility rates were to decline dramatically among adolescent women in developing countries, their sheer numbers imply that their fertility will have a major impact on world population growth in the years ahead. The number of women in the world ages 15-19 years is expected to increase from 245 million in 1985 to over 320 million in the years 2020; 82% of these women live in developing countries. As a result of more and earlier premarital sexual activity, fostered by the lengthening gap between puberty and marriage, diminished parental and social controls, and increasing peer and media pressure to be sexually active, abortion and out-of-wedlock childbearing are increasing among teenagers in many developed and rapidly urbanizing developing countries. Laws and policies regarding sex education in the schools and access to family planning services by adolescents can either inhibit or support efforts to reduce adolescent fertility. Since contraceptive use is often sporadic and ineffective among adolescents, family planning services are crucial. Such programs should aim to reduce adolescents' dependence on abortion through preventive measures and increase awareness of the benefits of delayed sexual activity. Similarly, sex

    Obesity, a global health epidemic, requires targeted interventions to promote sustainable health behavior change; yet, prior efforts have not yielded significant improvements in obesity rates. Using Photovoice as a data collection approach, this community-engaged research study partnered with a weight management program to understand participants' perspectives on access to physical activity and nutritious food. Twelve adolescent-parent dyads participated. Barriers, facilitators, and opportunities for change were identified and categorized through adolescent photographs, interviews, and participant focus groups, according to the social ecological model. A community-engaged research approach can identify areas to increase health promotion and prevention efforts regarding physical activity and nutrition. PMID:27536935

    The appropriateness of applying risk coefficients calculated from short-term exposures at high doses for the assessment of radiation effects at low doses is currently much debated. The problem can be resolved on the basis of the data obtained from a long-term follow-up of the population exposed in the early 1950s when discharges of radioactive wastes from a radiochemical plant into the Techa River (southern Urals) occurred. This paper discusses the results of an analysis of cancer mortality during the period 1950-82. 10 refs., 5 figs., 8 tabs.

    The objectives of this work are as follows: to establish a Blood Bio-sample Database of three generations families living close to the Semipalatinsk test site (STS) and control families in three generation from clean areas; to determine the mini-satellite mutations rates in the three generation of radiation exposed people and control families of the same ethnic origin; to definition the chromosomal translocation frequencies by FISH chromosome painting in the lymphocytes of the exposed and control people in order to determine the radiation exposure. The following criteria for select to examined groups were used: the people from control group should be permanently living at clean area (far from STS or any places where the nuclear tests occur and far from any chemical industrial plants), e.g. they should not been exposed to radiation during their life (including a radiotherapy and cytostatics); the people of both examined groups should be matched regard to structure of families, age, ethnic background, parental age of P0 and F1 to the moment children birth, smoking habit, lifestyle and occupation. The maximum of available families by appropriate criteria in villages were chosen. As exposed inhabitation serves residents of following villages: Dolon, Mostik, Bodene, Cheremushki, Kanonerka, Karamyrza (all these villages are situated in Beskargai district). The inhabitants of Dzerzhinsk, Zhanatalap and Ushtobe villages of former Taldy-Kurgan oblast were included for study as a control group.

    For any system, whether physical or non-physical, knowledge of the form and strength of inter-individual interactions is a key-information. In an approach based on statistical physics one needs to know the interaction Hamiltonian. For non-physical systems, based on qualitative arguments similar to those used in physical chemistry, interaction strength gives useful clues about the macroscopic properties of the system. Even though our ultimate objective is the understanding of social phenomena, we found that systems composed of insects (or other living organisms) are of great convenience for investigating group effects. In this paper we show how to design experiments that enable us to estimate the strength of interaction in groups of insects. By repeating the same experiments with increasing numbers of insects, ranging from less than 10 to several hundreds, one is able to explore key-properties of the interaction. The data turn out to be consistent with a global correlation that is independent of distance (at l...

    To determine the effect of agricultural management on the dynamics and functional diversity of soil nematode communities in a carrot field at Kibbutz Ramat Hakovesh, Israel, soil samples from 0-10 cm and 10-20 cm depths were collected during the growing season of carrot. Indices were used to compare and assess the response of soil free-living nematode communities to agricultural management. Eighteen nematode families and 20 genera were observed during the growing period, with Cephalobus, Rhabditidae, Aphelenchus, Tylenchus, and Dorylaimus being the dominant genera/families.During the planting, mid-season and post-harvest periods the total number of nematodes at both depths was significantly lower (P < 0.01) in the carrot treatment than in the control plots, while during the harvest period at both depths total nematodes and bacterivores were significantly higher in the treatment plots (P < 0.01). The values of the maturity index (MI) at both depths were found to be significantly lower in the treatment plots than in the control plots during the pre-planting period (P < 0.05). Overall, WI, MI and PPI were found to be more sensitive indicators than other ecological indices for assessing the response of nematode communities to agricultural management in a Mediterranean agroecosystem.

    On the basis of the previous investigation, 24,000 metaphases of the lymphocytes of 120 inhabitants from Tongyou region, where the highest individual cummulative exposure per year of 372 mR in weighted average was recorded in the high background radiation area selected, have been analysed with the method recommended by WHO in 1973, in order to determine the extent of human chromosome aberrations induced by the high background radiation of various levels. The results show that the difference between the total number of chromosome breakages in the individuals living in the high background radiation area and that in the control area (0.32x10/sup -2/ and 0.27x10/sup -2/ per cell respectively) is not significant whereas that between the numbers of two-hite aberrations (mainly dicentric) in the same two groups (0.042x10/sup -2/ and 0.0048x10/sup -2/ per cell) is significant (X/sup 2/ = 6.1475, P<0.05). In addition, the normal value of the chromosome aberrations of human lymphocytes was analyzed.

    Adolescent mothers are reportedly at risk for depression and problem behaviors in the postpartum period, but studies have rarely considered developmental context and have yet to disentangle the effects of childbearing on adolescent functioning from selection effects that are associated with early pregnancy. The current study examined changes in adolescent depression, conduct problems and substance use (alcohol, tobacco and marijuana) across the peripartum period using risk-set propensity scores derived from a population-based, prospective study that began in childhood (the Pittsburgh Girls Study, PGS). Each of 147 childbearing adolescents (ages 12–19) was matched with two same-age, non-childbearing adolescents (n = 294) on pregnancy propensity using 15 time-varying risk variables derived from sociodemographic, psychopathology, substance use, family, peer and neighborhood domains assessed in the PGS wave prior to each pregnancy (T1). Postpartum depression and problem behaviors were assessed within the first 6 months following delivery (T2); data gathered from the non-childbearing adolescent controls spanned the same interval. Within the childbearing group, conduct problems and marijuana use reduced from T1 to T2, but depression severity and frequency of alcohol or tobacco use showed no change. When change was compared across the matched groups, conduct problems showed a greater reduction among childbearing adolescents. Relative to non-childbearing adolescents who reported more frequent substance use with time, childbearing adolescents reported no change in alcohol use and less frequent use of marijuana across the peripartum period. There were no group differences in patterns of change for depression severity and tobacco use. The results do not support the notion that adolescent childbearing represents a period of heightened risk for depression or problem behaviors. PMID:27176826

    While a great deal of research has been conducted on prodromal risk syndromes in relation to help-seeking individuals who present to the clinic, there is a lack of research on prodromal risk syndromes in the general population. The current study aimed first to establish whether prodromal risk syndromes could be detected in non-help-seeking community-based adolescents and secondly to characterize this group in terms of Axis-1 psychopathology and general functioning. We conducted in-depth clinical interviews with a population sample of 212 school-going adolescents in order to assess for prodromal risk syndromes, Axis-1 psychopathology, and global (social\\/occupational) functioning. Between 0.9% and 8% of the community sample met criteria for a risk syndrome, depending on varying disability criteria. The risk syndrome group had a higher prevalence of co-occurring nonpsychotic Axis-1 psychiatric disorders (OR = 4.77, 95% CI = 1.81-12.52; P < .01) and poorer global functioning (F = 24.5, df = 1, P < .0001) compared with controls. Individuals in the community who fulfill criteria for prodromal risk syndromes demonstrate strong similarities with clinically presenting risk syndrome patients not just in terms of psychotic symptom criteria but also in terms of co-occurring psychopathology and global functioning.

    Life history theory and associated empirical generalizations predict that population growth rate (lambda) in long-lived animals should be most sensitive to adult survival; the rates to which lambda is most sensitive should be those with the smallest temporal variances; and stochastic environmental events should most affect the rates to which lambda is least sensitive. To date, most analyses attempting to examine these predictions have been inadequate, their validity being called into question by problems in estimating parameters, problems in estimating the variability of parameters, and problems in measuring population sensitivities to parameters. We use improved methodologies in these three areas and test these life-history predictions in a population of red-tailed tropicbirds (Phaethon rubricauda). We support our first prediction that lambda is most sensitive to survival rates. However the support for the second prediction that these rates have the smallest temporal variance was equivocal. Previous support for the second prediction may be an artifact of a high survival estimate near the upper boundary of 1 and not a result of natural selection canalizing variances alone. We did not support our third prediction that effects of environmental stochasticity (El Ni?o) would most likely be detected in vital rates to which lambda was least sensitive and which are thought to have high temporal variances. Comparative data-sets on other seabirds, within and among orders, and in other locations, are needed to understand these environmental effects.

    Habitats in agroecosystems are ephemeral, and are characterized by frequent disturbances forcing pest species to successively colonize various hosts belonging either to the cultivated or to the uncultivated part of the agricultural landscape. The role of wild habitats as reservoirs or refuges for the aphid Sitobion avenae that colonize cultivated fields was assessed by investigating the genetic structure of populations collected on both cereal crops (wheat, barley and oat) and uncultivated hosts (Yorkshire fog, cocksfoot, bulbous oatgrass and tall oatgrass) in western France. Classical genetic analyses and Bayesian clustering algorithms indicate that genetic differentiation is high between populations collected on uncultivated hosts and on crops, revealing a relatively limited gene flow between the uncultivated margins and the cultivated part of the agroecosystem. A closer genetic relatedness was observed between populations living on plants belonging to the same tribe (Triticeae, Poeae and Aveneae tribes) where aphid genotypes appeared not to be specialized on a single host, but rather using a group of related plant species. Causes of this ecological differentiation and its implications for integrated pest management of S. avenae as cereals pest are discussed. PMID:16024367

    Full Text Available Introduction: malnutrition refers to imbalances (either deficit or excess in energy intake, protein and / or nutrients including underweight and obesity. The aim of this work is identify the contribution of individual factors, habits and life conditions in nutritional status. Material and methods: estimates of relative risk ratios are obtained from a multinomial logistic model using microdata from the National Survey of Risk Factors conducted in 2005 and 2009 in Argentinean‘ cities among adult population. Results: malnutrition is associated with constitutive and socioeconomic variables, while habits are also important in the obesity case. Discussion: both types of problems coexist in Argentine due to high heterogeneity in life styles, turning difficult the design of public interventions aimed to solve them. This complexity highlights the importance of a careful and specific multidimensional approach (medical, social, economical.

  19. Water intake in an Asian population living in arsenic-contaminated area

    International Nuclear Information System (INIS)

    Exposure evaluation is an indispensable step for the risk assessment of chronic arsenic toxicity. The amount of water intake, which consists of the base of exposure calculation, has been lacking for the arsenic-affected populations in the developing countries. Thus, the purposes of the present study were (1) to estimate the water intake in such population, and (2) to estimate the relative importance of water versus food as the source of arsenic exposure. Adult males and females (n = 19 for each) were selected from two rural Bangladeshi communities that entirely depended on tubewells for their water supply. Their water intake was measured by two methods, a 24-h self-report and an interview with frequent visits. Results of the two methods generally agreed with each other in terms of correlation and the absolute intakes. Mean water intake obtained by the self-report method was found to be around 3 l/day with substantial individual variation (the maximum = 6 l/day), no sex difference, and a significant between-community difference. The calculation for total arsenic exposure demonstrated that there was no sex difference in arsenic exposure except when the exposure was mainly from food and thus relatively low. Although these results need to be further confirmed under various environmental settings, these results suggested that (1) the sex difference in the manifestation of arsenic toxicity previously observed in this area should be related with factors other than exposure level and that (2) the risks associated with low arsenic concentrations of groundwater should be carefully interpreted because food may be providing additional burden of arsenic

    More than twenty thousand inhabitants of Siberia and the Urals, subjected to a radiating effect a result of explosions on the Semipalatinsk nuclear range and after failures at the enterprises making elements of nuclear weapons (Tomsk-7- a Siberian chemical combine and Cheliabinsk - the industrial association open-quotes Majakclose quotes) were investigated by genetic methods (chromosomatic, micronuclear and DNA-repair tests). Scientists from the Netherlands (A.T. Natarajam), Russia (I.Suskov and N.Ilyinskikh) have established, that high accumulated doses of radiation are observed in people, living near to Siberian chemical combine (Tomsk-7). It has been established, that the effective equivalent dose of radiation much exceeded the level which the person can receive for life from natural sources of radiation in more than 50% of the cases. In some people this dose was much higher 1 Gy. A high level of cells with cytogenetic breaks were predominantly observed in the people born in periods when there were radiating failures or open-quotes dirtyclose quotes nuclear tests on Semipalatinsk nuclear range. We assume that the long preservation in the body of the person of genetic instability is stipulated by occurrence of genetically defective cells in the person in the prenatal period of life. It has been established, that in the long term effects of radiation, the following changes are observed in the people: the number erythrocytes with micronuclei. T-lymphocytes with micronuclei and chromosomic breaks is increased, thus the activity excessive DNA-repair is reduced. Ring and dicentric chromosomes prevailed among other types of cytogenetic breaks in lymphocytes. Genetic instability was accompanied by essential haematologic and immunologic changes. Reduced ability of lumphoid of cells to product interferon and DNA-repair was observed in the people with high cytogenetic instability

    Full Text Available BACKGROUND: The Child and Adolescent Twin Study in Sweden (CATSS is an on-going, large population-based longitudinal twin study. We aimed (1 to investigate the reliability of two different versions (125-items and 238-items of Cloninger's Temperament and Character Inventory (TCI used in the CATSS and the validity of extracting the short version from the long version, (2 to compare these personality dimensions between twins and adolescents from the general population, and (3 to investigate the genetic structure of Cloninger's model. METHOD: Reliability and correlation analyses were conducted for both TCI versions, 2,714 CATSS-twins were compared to 631 adolescents from the general population, and the genetic structure was investigated through univariate genetic analyses, using a model-fitting approach with structural equation-modeling techniques based on same-sex twin pairs from the CATSS (423 monozygotic and 408 dizygotic pairs. RESULTS: The TCI scores from the short and long versions showed comparable reliability coefficients and were strongly correlated. Twins scored about half a standard deviation higher in the character scales. Three of the four temperament dimensions (Novelty Seeking, Harm Avoidance, and Persistence had strong genetic and non-shared environmental effects, while Reward Dependence and the three character dimensions had moderate genetic effects, and both shared and non-shared environmental effects. CONCLUSIONS: Twins showed higher scores in character dimensions compared to adolescents from the general population. At least among adolescents there is a shared environmental influence for all of the character dimensions, but only for one of the temperament dimensions (i.e., Reward Dependence. This specific finding regarding the existence of shared environmental factors behind the character dimensions in adolescence, together with earlier findings showing a small shared environmental effects on character among young adults and no

    Almost all bacterial genomes contain DNA of viral origin, including functional prophages or degenerated phage elements. A frequent but often unnoted phenomenon is the spontaneous induction of prophage elements (SPI) even in the absence of an external stimulus. In this study, we have analyzed SPI of the large, degenerated prophage CGP3 (187 kbp), which is integrated into the genome of the Gram-positive Corynebacterium glutamicum ATCC 13032. Time-lapse fluorescence microscopy of fluorescent reporter strains grown in microfluidic chips revealed the sporadic induction of the SOS response as a prominent trigger of CGP3 SPI but also displayed a considerable fraction (∼30%) of RecA-independent SPI. Whereas approx. 20% of SOS-induced cells recovered from this stress and resumed growth, the spontaneous induction of CGP3 always led to a stop of growth and likely cell death. A carbon source starvation experiment clearly emphasized that SPI only occurs in actively proliferating cells, whereas sporadic SOS induction was still observed in resting cells. These data highlight the impact of sporadic DNA damage on the activity of prophage elements and provide a time-resolved, quantitative description of SPI as general phenomenon of bacterial populations.

    The objective of this study was to describe breastfeeding practices and to compare the risk of suboptimal breastfeeding of women living in Denmark according to country of origin, and further to examine how socio-economic position and duration of stay in the country affected this risk. Information on breastfeeding of 42,420 infants born 2002-2009 and living in eighteen selected Danish municipalities was collected from the Danish Health Visitor's Child Health Database. The data was linked with data on maternal socio-demographic information from Danish population-covering registries. Suboptimal breastfeeding was defined as Pakistan, adjustment for socio-demographic indicators (age, parity, education, attachment to labour market, and income) eliminated the increased risk of suboptimal breastfeeding. There was no evidence for differences in the breastfeeding support provided at hospital level according to migrant status. Suboptimal breastfeeding was more frequent among women who were non-Nordic migrants and descendants of migrants than among women with Danish origin. PMID:24748214

    Cytogenetic examination of groups of people from ecologically unfavourable region of 4 settlements located at different distance from the center of nuclear explosions was conducted. For purpose of conducting biological indication and dosimetry, the radio sensibility of cells peripheral blood was determined with the account for the sex and age of the individuals from examined groups of people. Correlation analysis of frequency of chromosome aberration (CA) was implement taking into account the sex, age and absorbed dose of radiation. It was established that the frequency of chromosome aberration in examined groups exceed the control level 3,5 times (1,63±0,26). It was shown that total frequency of CA from people constituted: the Dolon settlement (zone of extreme risk) - 6,16±1,23 per 100 analyzed metaphases; the Kononerka settlement (zone of maximum risk) - 4,4 ±0,84; the Ramadan settlement (zone of maximum risk) - 5,97±1,08. Frequency of radiation induction chromosome markets within the region constituted 0,41±0,16 per 100 cells as average, - this exceeds control level (0,67±0,002) 6 times. Considerable factions (0,5-17,7 %) of exit of chromosome aberrations were discovered among different individuals. It was established that the frequency of stable and unstable CA increases due to the age of the people examined. Using the method of biological dosimetry based of registration of frequency of stable and unstable CA it was established that the population of examined regions has probably absorbed the following doses: the Dolon settlement - 0,14 Gy, the Kanonerka settlement - 0,13 Gy, the Buras settlement - 0,06 Gy, the Ramadan - 0,095 Gy.

    Directory of Open Access Journals (Sweden)

    Camilla Rams Rathleff

    Full Text Available BACKGROUND: One of the rationales behind using strength training in the treatment of adolescents with Patellofemoral Pain (PFP is that reduced strength of the lower extremity is a risk factor for PFP and a common deficit. This rationale is based on research conducted on adolescents >15 years of age but has never been investigated among young adolescents with PFP. OBJECTIVES: To compare isometric muscle strength of the lower extremity among adolescents with PFP compared to age- and gender-matched pain-free adolescents. METHODS: In 2011 a population-based cohort (APA2011-cohort consisting of 768 adolescents aged 12-15 years from 8 local schools was formed. In September 2012, all adolescents who reported knee pain in September 2011 were offered a clinical examination if they still had knee pain. From these, 20 adolescents (16 females were diagnosed with PFP. Pain-free adolescents from the APA2011-cohort (n = 20 were recruited on random basis as age- and gender-matched pairs. Primary outcome was isometric knee extension strength normalized to body weight (%BW and blinded towards subject information. Secondary outcomes included knee flexion, hip abduction/adduction and hip internal/external rotation strength. Demographic data included Knee Injury and Osteoarthritis Outcome Score (KOOS and symptom duration. RESULTS: Adolescents with PFP reported long symptom duration and significantly worse KOOS scores compared to pain-free adolescents. There were no significant differences in isometric knee extension strength (Δ0.3% BW, p = 0.97, isometric knee flexion strength (Δ0.4% BW, p = 0.84 or different measures of hip strength (Δ0.4 to 1.1% BW, p>0.35. CONCLUSION: Young symptomatic adolescents with PFP between 12 and 16 years of age did not have decreased isometric muscle strength of the knee and hip. These results question the rationale of targeting strength deficits in the treatment of adolescents with PFP. However, strength training may

    Full Text Available Introduction: The high prevalence of overweight and obesity is a health problem in Cuba, and there is a lack of information on adolescents. The objective of the present study was to evaluate the relationship between excessive weight and adiposity with physical activity, hours of television (TV, and eating habits in adolescents.Material and methods: A total of 604 adolescents (12 years from Havana were studied. The variables analysed included, body mass index, body composition, history of obesity in infancy, physical activity, hours watching television, eating habits and dietary preferences. A descriptive and correlation analysis was performed. In the logistic regression analysis, excess weight and adiposity were used as dependent variables.Results: Excess body weight was more common in boys. There was high prevalence of excess adiposity, 49.8% in girls and 37.8% in boys. The boys (61.7% were more active than the girls (33.6%. Just under half (46.7% of the boys, and 55.9% of the girls spent more than 2 hours/day watching television, which increased to more than 75% for both sexes on Saturdays and Sunday. Making less than 5-6 meals/day doubled the risk of being overweight. Body overweight in infancy was also a risk factor. Not having breakfast increased the risk of adiposity by almost double.Conclusions: Excess weight, and particularly excess adiposity, may be considered a health problem in the adolescents studied. A very high consumption of sugar, an excessive time watching TV, and insufficient physical activity was observed.

    Full Text Available AIM: To investigate the factors predicting adolescent visits to practitioners of complementary and alternative medicine (CAM. METHODS: A longitudinal cohort study conducted in an adolescent total population in Central Norway (The Nord-Trøndelag Health Studies (HUNT. In Young-HUNT 1, all inhabitants aged 13 to 19 years (N = 8944, 89% response rate were invited to participate, and the youngest group (13 to 15 year olds was surveyed again 4 years later (Young-HUNT 2, N = 2429, 82% response rate. The participants completed a comprehensive questionnaire on health and life style which included a question regarding visits to a CAM practitioner in the last 12 months. RESULTS: One in eleven (8.7%, 95%CI 7.6-9.8% had visited a CAM practitioner, an increase of 26% in 4 years (1.8% points. The final multivariable analysis predicted increased odds of an adolescent becoming a CAM visitor four years later (p<0.05 if she or he had previously visited a CAM practitioner (adjOR 3.4, had musculoskeletal pain (adjOR 1.5, had migraine (adjOR 2.3, used asthma medicines (adjOR 1.8 or suffered from another disease lasting more than three months (adjOR 2.1. Being male predicted reduced odds of visiting a CAM practitioner in the future (adjOR 0.6. CONCLUSION: We can conclude from this study that future visits to a CAM practitioner are predicted by both predisposing factors (being female, having visited a CAM practitioner previously and medical need factors (having had musculoskeletal pain, migraine, used asthma medicines or experienced another disease lasting more than three months. None of the specific variables associated with CAM visits were predictive for CAM visits four years later.

  15. Routine clinical measures of adiposity as predictors of visceral fat in adolescence: a population-based magnetic resonance imaging study.

    Katie Goodwin

    Full Text Available OBJECTIVE: Visceral fat (VF increases cardiometabolic risk more than fat stored subcutaneously. Here, we investigated how well routine clinical measures of adiposity, namely body mass index (BMI and waist circumference (waist, predict VF and subcutaneous fat (SF in a large population-based sample of adolescents. As body-fat distribution differs between males and females, we performed these analyses separately in each sex. DESIGN AND METHODS: VF and SF were measured by magnetic resonance imaging in 1,002 adolescents (482 males, age 12-18 years. Relationships of BMI and waist with VF and SF were tested in multivariable analyses, which adjusted for potentially confounding effects of age and height. RESULTS: In both males and females, BMI and waist were highly correlated with VF and SF, and explained 55-76% of their total variance. When VF was adjusted for SF, however, BMI and waist explained, respectively, only 0% and 4% of VF variance in males, and 4% and 11% of VF variance in females. In contrast, when SF was adjusted for VF, BMI and waist explained, respectively, 36% and 21% of SF variance in males, and 48% and 23% of SF variance in females. These relationships were similar during early and late puberty. CONCLUSIONS AND RELEVANCE: During adolescence, routine clinical measures of adiposity predict well SF but not VF. This holds for both sexes and throughout puberty. Further longitudinal studies are required to assess how well these measures predict changes of VF and SF over time. Given the clinical importance of VF, development of cost-effective imaging techniques and/or robust biomarkers of VF accumulation that would be suitable in everyday clinical practice is warranted.

  16. We Happy Few: Using Structured Population Models to Identify the Decisive Events in the Lives of Exceptional Individuals.

    In any population, some individuals make it big: they are among the few that produce many offspring, grow to large size, and so on. What distinguishes the lives of these happy few? We present three approaches for identifying what factors distinguish those "lucky" individuals who come to dominate reproduction in a population without fixed differences between individuals (genotype, site quality, etc.): comparing life-history trajectories for lucky and unlucky individuals and calculating the elasticity of the probability of becoming lucky to perturbations in demographic rates at a given size or a given age. As examples we consider published size-structured integral projection models for the tropical tree Dacrydium elatum and the semiarid shrub Artemisia ordosica and an age-size-structured matrix model for the tropical tree Cedrela ordosica. We find that good fortune (e.g., rapid growth) when small and young matters much more than good fortune when older and larger. Becoming lucky is primarily a matter of surviving while others die. For species with more variable growth (such as Cedrela and Ordosica), it is also a matter of growing fast. We focus on reproductive skew, but our methods are broadly applicable and can be used to investigate how individuals come to be exceptional in any aspect. PMID:27420793

    Adolescent girls face unique challenges in health care utilization, which can result in unmet needs. We sought to describe settings of usual care and primary care use, and to identify predictors of foregone care and experience of confidential care in a primarily racial/ethnic minority low-income sample. We conducted an anonymous computer-assisted self-administered survey of 9th-12th grade girls (n=819) in three Bronx public high schools, the majority of whom were Hispanic (69.8%) and Black (21.4%). Most (80%) reported having a usual source of care. Of these, 77.2% had a regular doctor. Those least likely to have a usual source of care were non-U.S. born girls (73.1% vs. 83.1%) and less acculturated girls. Predictors of foregone care in the last year include being sexually active, poor family social support, and low self esteem. Predictors of access to confidential care at last visit were age, self-efficacy for confidential care, having a regular doctor, setting of care, and having had a recent physical exam. Many urban adolescent girls, especially non-U.S. born girls, lack a usual source of care and regular health care provider. Continued attention to reducing both financial and non-financial barriers to care is required to ensure access to and quality of care for diverse populations. PMID:17242529

Body composition was determined by bioelectric impedance analysis (BIA. The homeostatic model assessment of IR (HOMA-IR, based on fasting glucose and insulin concentrations, was used to estimate IR. Stepwise linear regression analyses were performed to predict HOMA-IR based on the six selected measures, while controlling for age.Results: The stepwise regression retained both waist circumference (WC and percentage of body fat (BF%. Notably, BMI was not retained. WC was a stronger predictor of HOMA-IR than BMI was. A regression model using solely WC performed best among the obese II group, while a model using solely BF% performed best among the lean group. Receiver operator characteristic curves showed the WC and BF% model to be more sensitive in detecting IR than BMI, but with less specificity.Conclusion: WC combined with BF% was the best predictor of HOMA-IR. This finding can be attributed partly to the ability of BF% to model HOMA-IR among leaner participants and to the ability of WC to model HOMA-IR among participants who are more obese. BMI was comparatively weak in predicting IR, suggesting that assessments that are more comprehensive and include body composition analysis could increase detection of IR during adolescence, especially among those who are lean, yet insulin-resistant.Keywords: BMI, bioelectrical impedance

    Nine adolescent females were enrolled in a prenatal course that included the PREP for Effective Family Living Program (the treatment group). Two comparison groups were utilized in this study; one attended the prenatal group without the PREP program, and the second did not attend either the prenatal course or the PREP program. The Coopersmith Self-Esteem Inventory and the Attitude Toward the Freedom of Children Scale (a parental attitude scale) was administered to all participants. No significant difference was found among the three groups in terms of self-concept. A significant difference was found among the three groups in terms of parental attitudes, with the treatment group scoring higher on democratic parenting attitudes than did the two comparison groups.

    Full Text Available Abstract Background While suicide is the second leading cause of death among young people in most industrial countries, non-fatal suicidal behaviour is also a very important public health concern among adolescents. The aim of this study was to investigate gender differences in prevalence and emotional and behavioural correlates of suicidal behaviour in a representative school-based sample of adolescents. Methods A cross-sectional design was used to assess suicidal behaviour and various areas of emotional and behavioural problems by using a self-report booklet including the Youth Self-Report. One hundred sixteen schools in a region of Southern Germany agreed to participate. A representative sample of 5,512 ninth-grade students was studied. Mean age was 14.8 years (SD 0.73; 49.8% were female. Results Serious suicidal thoughts were reported by 19.8% of the female students and 10.8% of the females had ever attempted suicide. In the male group, 9.3% had a history of suicidal thoughts and 4.9% had previously attempted suicide. Internalizing emotional and behavioural problems were shown to be higher in the female group (difference of the group means 4.41 while externalizing emotional and behavioural problems slightly predominated in male students (difference of the group means -0.65. However, the total rate of emotional and behavioural problems was significantly higher in the adolescent female group (difference of the group means 4.98. Using logistic regression models with suicidal thoughts or attempted suicide as dependent variables, the pseudo-R2 of gender alone was only 2.7% or 2.3%, while it was 30% or 23.2% for emotional and behavioural problems measured by the YSR syndrome scales. By adding gender to the emotional and behavioural problems only an additional 0.3% of information could be explained. Conclusions The findings suggest that gender differences in non-fatal suicidal behaviour among adolescents can to a large extent be explained by the

    Cutaneous synthesis of vitamin D by exposure to UVB is the principal source of vitamin D in the human body. Our current clothing habits and reduced time spent outdoors put us at risk of many insufficiency-related diseases that are associated with calcaemic and non-calcaemic functions of vitamin D. Populations with traditional lifestyles having lifelong, year-round exposure to tropical sunlight might provide us with information on optimal vitamin D status from an evolutionary perspective. We measured the sum of serum 25-hydroxyvitamin D₂ and D₃ (25(OH)D) concentrations of thirty-five pastoral Maasai (34 (SD 10) years, 43 % male) and twenty-five Hadzabe hunter-gatherers (35 (SD 12) years, 84 % male) living in Tanzania. They have skin type VI, have a moderate degree of clothing, spend the major part of the day outdoors, but avoid direct exposure to sunlight when possible. Their 25(OH)D concentrations were measured by liquid chromatography-MS/MS. The mean serum 25(OH)D concentrations of Maasai and Hadzabe were 119 (range 58-167) and 109 (range 71-171) nmol/l, respectively. These concentrations were not related to age, sex or BMI. People with traditional lifestyles, living in the cradle of mankind, have a mean circulating 25(OH)D concentration of 115 nmol/l. Whether this concentration is optimal under the conditions of the current Western lifestyle is uncertain, and should as a possible target be investigated with concomitant appreciation of other important factors in Ca homeostasis that we have changed since the agricultural revolution.

  10. Cancer in populations living near nuclear facilities. A survey of mortality nationwide and incidence in two states

    International Nuclear Information System (INIS)

    Reports from the United Kingdom have described increases in leukemia and lymphoma among young persons living near certain nuclear installations. Because of concerns raised by these reports, a mortality survey was conducted in populations living near nuclear facilities in the United States. All facilities began service before 1982. Over 900,000 cancer deaths occurred from 1950 through 1984 in 107 counties with or near nuclear installations. Each study county was matched for comparison to three control counties in the same region. There were 1.8 million cancer deaths in the 292 control counties during the 35 years studied. Deaths due to leukemia or other cancers were not more frequent in the study counties than in the control counties. For childhood leukemia mortality, the relative risk comparing the study counties with their controls before plant start-up was 1.08, while after start-up it was 1.03. For leukemia mortality at all ages, the relative risks were 1.02 before start-up and 0.98 after. For counties in two states, cancer incidence data were also available. For one facility, the standardized registration ratio for childhood leukemia was increased significantly after start-up. However, the increase also antedated the operation of this facility. The study is limited by the correlational approach and the large size of the geographic areas (counties) used. It does not prove the absence of any effect. If, however, any excess cancer risk was present in US counties with nuclear facilities, it was too small to be detected with the methods employed

    In the period from 1949 to 1956, liquid radioactive waste was routinely and accidentally discharged by the Mayak Production Association, Southern Urals, Russia, into the Techa river. Based on a novel approach, the contamination of the Techa river water, the bottom sediments and the adjacent flood plains was modelled, and internal and external doses were estimated for two villages located downstream of the site of liquid radioactive waste release. Altogether, 11 radionuclides that occurred in the liquid radioactive waste were included in the calculations. The results suggest significantly higher doses than previously assumed, with the major contribution in the year 1951. Radionuclides with half-lives of less than 1 year, such as 89Sr, 131I, 95Zr+95Nb, 103Ru+103mRh, 140Ba+140La, and 144Ce+144Pr, represent the major sources and, in contrast, long-lived radionuclides, such as 90Sr and 137Cs that have so far been assumed to be most important, did not dominate the doses. For adults from the village Metlino, located 7 km downstream of the site of liquid radioactive waste discharge, the committed effective doses due to intake of radionuclides were calculated to be about 2.3 Sv, while the external doses were between about 1.2 Sv and 6.9 Sv. On the other hand, for adults from Muslyumovo, located 75 km downstream, the committed effective doses due to intake of radionuclides were calculated to be about 0.5 Sv, while the external doses were between 0.5 Sv and 2.0 Sv. The values for the skin doses to the Metlino and Muslyumovo populations were about 7.1 Sv and 1.3 Sv, respectively. It is concluded that the current dose estimates for the residents of the Techa river need, therefore, reevaluation. PMID:15378312

    Background Acne vulgaris is a pilosebaceous follicle disorder affecting over 85% of adolescents to some degree. It frequently causes psychological distress that may persist into adulthood due to scarring. Little information about post-acne scarring epidemiology is available. Objectives To describe prevalence, distribution patterns and associated factors of acne scarring in young males, drawing on a representative population sample from a southern Brazilian city. Methods A cross-sectional study was undertaken during presentation for military service, which is compulsory for all 18-year-old males. A questionnaire was applied, covering topics like diet, smoking habits, ethnicity, family structure, socio-economic level, as well as specific questions about active acne and resulting scars. Dermatologists conducted the clinical examination. Results A total of 2,201 male adolescents were interviewed and examined. The overall prevalence of acne scarring was 22%. The malar region was the most frequently involved, present in 80% of affected individuals, followed by the frontal region (31.5%), back (17%), anterior chest (8.2%) and mentonian region (6.4%). Correlation between the intensity of clinical acne and the presence of scars was found, but no association was observed with educational level, smoking, ethnicity, obesity or socio-economic status. Conclusions There is a high prevalence of acne scars among this population. This is the first study to ascertain a correlation between acne scarring and factors such as socio-economic status and educational level. The direct relation between acne severity and scarring indicates that prompt and effective treatment is the best way to reduce scarring. PMID:27438194

    Full Text Available BACKGROUND: Infections with different herpes viruses have been associated with cognitive functioning in psychiatric patients and healthy adults. The aim of this study was to find out whether antibodies to different herpes viruses are prospectively associated with cognitive functioning in a general adolescent population. METHODS: This study was performed in TRAILS, a large prospective general population cohort (N = 1084, 54% female, mean age 16.2 years (SD 0.6. At age 16, immunoglobulin G antibodies against HSV1, HSV2, CMV and EBV were measured next to high sensitive C-Reactive Protein (hsCRP. Two years later, immediate memory and executive functioning were assessed using the 15 words task and the self ordered pointing task. Multiple linear regression analysis with bootstrapping was performed to study the association between viral infections and cognitive function, adjusting for gender, socioeconomic status, ethnicity, and cannabis use. RESULTS: Presence of HSV1 antibodies was associated with memory function ((B = -0.272, 95% CI = -0.556 to -0.016, p = 0.047, while the association with executive functioning did not reach statistical significance (B = 0.560, 95% CI is -0.053 to 1.184, p = 0.075. The level of HSV1 antibodies was associated with both memory function (B = -0.160, 95% CI = -0.280 to -0.039, p = 0.014 and executive functioning (B = 0.296, 95% CI = 0.011 to 0.578, p = 0.046. Other herpes viruses and hsCRP were not associated with cognitive functioning. CONCLUSIONS: Both presence and level of HSV1 antibodies are prospectively associated with reduced cognitive performance in a large cohort of adolescents.

    Full Text Available Abstract Background The negative effects of stigma on persons living with HIV (PLHIV have been documented in many settings and it is thought that stigma against PLHIV leads to more difficulties for those who need to access HIV testing, treatment and care, as well as to limited community uptake of HIV prevention and testing messages. In order to understand and prevent stigma towards PLHIV, it is important to be able to measure stigma within communities and to understand which factors are associated with higher stigma. Methods To analyze patterns of community stigma and determinants to stigma toward PLHIV, we performed an exploratory population-based survey with 1874 randomly sampled adults within a demographic surveillance site (DSS in rural Vietnam. Participants were interviewed regarding knowledge of HIV and attitudes towards persons living with HIV. Data were linked to socioeconomic and migration data from the DSS and latent class analysis and multinomial logistic regression were conducted to examine stigma group sub-types and factors associated with stigma group membership. Results We found unexpectedly high and complex patterns of stigma against PLHIV in this rural setting.

Women had the greatest odds of belong to the highest stigma group (OR 1.84, 95% CI 1.42-2.37), while those with more education had lower odds of highest stigma group membership (OR 0.45, 95% CI 0.32-0.62 for secondary education; OR 0.19, 95% CI 0.10-0.35 for tertiary education). Long-term migration out of the district (OR 0.61, 95% CI 0.4-0.91), feeling at-risk for HIV (OR 0.42, 95% CI 0.27-0.66), having heard of HIV from more sources (OR 0.44, 95% CI 0.3-0.66), and knowing someone with HIV (OR 0.76, 95% CI 0.58-0.99) were all associated with lower odds of highest stigma group membership. Nearly 20% of the population was highly unsure of their attitudes towards PLHIV and persons in this group had significantly lower odds of feeling at-risk for HIV (OR 0.54, 95% CI 0.33-0.90) or of knowing

    Full Text Available Background Facial fractures are infrequent in children and adolescents and have differentclinical features from those in adults. The low incidence in children and adolescents reflectsthe flexibility and underdevelopment of their facial skeletons, as well as their more protectedenvironments. Only a few reports have reviewed such patients in Korea. The authors performeda retrospective study to analyze the characteristics of facial fractures in the Korean pediatricpopulation.Methods We conducted a retrospective review on a series of 741 patients, aged <18 years,with facial fractures who had been treated at our hospital between 2006 and 2010. Thefollowing parameters were evaluated: age, sex, cause, location and type of fractures, associatedinjuries, treatment and complications.Results A total of 741 consecutive patients met the inclusion criteria. The ratio of boys to girlswas 5.7:1. Facial fractures most commonly occurred in patients between 13 and 15 years ofage (36.3%. The most common causes of injury was violence. The nasal fracture was the mostcommon type of fracture (69% and the blowout fracture was the second most common (20%.Associated injuries occurred in 156 patients (21%.Conclusions The incidence of pediatric facial fractures caused by violence is high in Korea.Our results show that as age increases, etiological factors and fracture patterns gradually shifttowards those found in adults. This study provides an overview of facial fractures in these agegroups that helps illustrate the trends and characteristics of the fractures and may be helpfulin further evaluation and management.

    Full Text Available The KADS-6 is a self-report assessment instrument known for its ease application in assessing depression in young people. This study aimed to contribute to the validation of the Portuguese version of this tool and analyze its psychometric characteristics in comparison with other self-report instruments for depression in adolescents, in Portugal. Two samples were collected, a non-clinical group of in school youth (n=773; 52.4% male and a clinical sample (n=134 youth; 44% male. Comparisons also used the Beck Depression Inventory (BDI-II and the Children's Depression Inventory (CDI. Results: The factor analysis revealed the unidimensionality of the measure. The KADS-6 demonstrated good internal consistency (Cronbach's alpha in both clinical (.74 and school (.80 samples. Its convergent validity with the BDI-II and CDI was r=.44; r=.61, respectively in the clinical sample and r=.60; r=.57 in the school sample. The KADS-6, a short and time efficient instrument, showed good psychometric characteristics in terms of internal consistency and convergent validity in comparison with the BDI-II and the CDI. Given its ease of use and scoring, the KADS-6 could be considered for use in both school and clinical settings when addressing adolescent depression.

    2015-01-01

    Full Text Available Introduction: Worldwide, HIV-related mortality among adolescents living with HIV (ALHIV increased by 50% from 2005 to 2012 and is attributed in part to a lack of support for adolescent retention to care and adherence to antiretroviral therapy (ART. This vulnerability reinforces the need to better understand incomplete ART adherence among ALHIV, particularly in sub-Saharan Africa, where the majority of the world's 2.1 million ALHIV reside. Methods: From December 2011 to February 2012, we conducted in-depth interviews with 32 ALHIV (aged 15 to 18 and 23 of their adult caregivers in the Copperbelt Province of Zambia. Interviews were transcribed and translated. An iterative qualitative process was used to code and analyze the data and main themes were summarized regarding the barriers to and facilitators of ART adherence. Results: More than a quarter of ALHIV reported missing a day or more of ART (ranging from one day to six months. Barriers to ART adherence included fear of disclosure and anticipated stigma. Few youth were willing to take their drugs outside of the home, which led to missed doses of ART. Similarly, families tended to manage HIV within the home only. As a result, although caregivers and families were often the greatest source of emotional and instrumental support, they coped with HIV in isolation of other potential support from their communities, schools or churches. Factors that supported ART adherence included attending clinic-sponsored youth groups, wanting to maintain one's health and using phone and clock alarms. Involvement of adult caregivers in HIV management varied greatly and was often based on the age and health status of the youth. Some caregivers struggled with letting the adolescents assume responsibility for their medication, and ALHIV had few self-management skills and tools to help them regularly take ART. Conclusions: These data highlight the importance of families and home environments in supporting adherence to

    Body segment parameters (BSP) for each body׳s segment are needed for biomechanical analysis. To provide population-specific BSP, precise estimation of body׳s segments volume and density are needed. Widely used uniform densities, provided by cadavers׳ studies, did not consider the air present in the lungs when determining the thorax density. The purpose of this study was to propose a new uniform thorax density representative of the living population from 3D external body shape modeling. Bi-planar X-ray radiographies were acquired on 58 participants allowing 3D reconstructions of the spine, rib cage and human body shape. Three methods of computing the thorax mass were compared for 48 subjects: (1) the Dempster Uniform Density Method, currently in use for BSPs calculation, using Dempster density data, (2) the Personalized Method using full-description of the thorax based on 3D reconstruction of the rib cage and spine and (3) the Improved Uniform Density Method using a uniform thorax density resulting from the Personalized Method. For 10 participants, comparison was made between the body mass obtained from a force-plate and the body mass computed with each of the three methods. The Dempster Uniform Density Method presented a mean error of 4.8% in the total body mass compared to the force-plate vs 0.2% for the Personalized Method and 0.4% for the Improved Uniform Density Method. The adjusted thorax density found from the 3D reconstruction was 0.74g/cm(3) for men and 0.73g/cm(3) for women instead of the one provided by Dempster (0.92g/cm(3)), leading to a better estimate of the thorax mass and body mass.

    Aims: To study socioeconomic status (SES) and living conditions (LC) as risk factors for latent tuberculosis infection (LTBI) and their impact on QuantiFERON-TB gold (QFT-G) and tuberculin skin test (TST) outcome for determining a better diagnostic test for LTBI in the malnourished tribal population of Melghat. Settings and Design: Six hundred sixty nine participants matching the inclusion criteria were recruited from 10 tribal villages of Melghat region, India. Subjects and Methods: Complete information related to various risk factors and test outcome was obtained on 398 participants, which was analyzed as per predefined conceptual framework. Factors were classified based on their relevance either at individual or household level, and subsequently based on the possibility of intervention. Data were partitioned into concordant and discordant sets depending on test agreement. Results: In concordant set, the two tests revealed that LTBI was significantly associated with smoking (adjusted odds ratio [aOR]: 2.64 [95% confidence interval [CI]: 1.03–6.79]), tobacco usage (aOR: 2.74 [95% CI: 1.50–4.99]), and malnourishment (aOR: 1.97 [95% CI: 1.12–3.48]) after basic adjustment. Inclusion of latent variable SES and LC in the model has mediating effect on the association of above factors with LTBI. Further, the association of SES and LC with LTBI in concordant set was unaltered in presence of other cofactors. From discordant set, results of QFT-G corroborated with that of concordant set. Conclusions: Poor SES and LC can be considered as strong risk factors linked with LTBI as compared to malnourishment, which is often targeted in such communities. Further, our study showed QFT-G test as a reliable tool in screening of LTBI in the tribal population of Melghat, India.

    Full Text Available Background: The Vestibular Disorders Activities of Daily Living Scale (VADL is considered an important subjective assessment to evaluate patients suffering from dizziness and imbalance. Although frequently used, its metric characteristics still require further investigation. Objective: This paper aims to analyze the psychometric properties of the Brazilian version of the VADL in an elderly population. Method: The sample comprises patients (≥65 years old with chronic dizziness resulting from vestibular disorders. For discriminant analysis, patients were compared to healthy subjects. All subjects answered the VADL-Brazil by interview. To examine the VADL validity, patients filled out the Dizziness Handicap Inventory (DHI and the ABC scale and were tested on the Dynamic Gait Index (DGI. To evaluate the VADL responsiveness, 20 patients were submitted to rehabilitation. Results: Patients (n=140 had a VADL total score of 4.1±1.6 points. Healthy subjects scored significantly less than patients in all the subscales and in the VADL total score. The VADL-Brazil was weakly correlated with the DHI and moderately to the ABC scale and the DGI. Instead of the original 3 subscales, factor analysis resulted in 6 factors. The VADL was capable of detecting changes after rehabilitation, which means that the instrument has responsiveness. Conclusions: This study provided more data about the psychometric properties and usefulness of the VADL-Brazil. The use of such a reliable and valid instrument increases the knowledge about disability in patients with vestibular disorders.

    2016-01-01

    As part of Villanova's Living with a Red Dwarf program, we have obtained UV, X-ray and optical data of the Population II red dwarf -- Kapteyn's Star. Kapteyn's Star is noteworthy for its large proper motions and high RV of ~+245 km s^-1. As the nearest Pop II red dwarf, it serves as an old age anchor for calibrating Activity/Irradiance-Rotation-Age relations, and an important test bed for stellar dynamos and the resulting X-ray -- UV emissions of slowly rotating, near-fully convective red dwarf stars. Adding to the notoriety, Kapteyn's Star has recently been reported to host two super-Earth candidates, one of which (Kapteyn b) is orbiting within the habitable zone (Anglada-Escude et al. 2014a, 2015). However, Robertson et al. (2015) questioned the planet's existence since its orbital period may be an artifact of activity, related to the star's rotation period. Because of its large Doppler-shift, measures of the important, chromospheric H I Lyman-alpha 1215.67A emission line can be reliably made, because it is...

    The accommodation of photosynthetic organisms to adverse conditions, such as pH changes in the aquatic environment, and their response to aquatic pollutants is essential to develop future biosensors. The present study reports the ability of both Cr(VI)-sensitive and tolerant Dyctiosphaerium chlorelloides strains to live in aqueous solutions highly contaminated with hexavalent chromium under varying ranges of pH, by the determination of chromium toxic effects on these strains. Studies of cell growth, photosynthetic quantum yield and gross photosynthesis rate show that both D. chlorelloides strains are able to survive in alkaline and moderately acidified (pH 4.25) aquatic environments. Below this pH value cell populations from both strains exposed for short periods of time to Cr(VI) showed alterations in the three parameters studied. There were no significant differences comparing the response of both strains at pH change in the culture medium. However, Cr(VI)-tolerant strain exhibits a better fit to maintain cell growth than Cr(VI)-sensitive strain when both were subjected to pH 4.25 in the culture medium. The absence of significant differences in photosynthetic activity results for both strains suggests that the lower sensitivity exhibited by Cr(VI)-tolerant strain would be due to cellular morphological changes rather than changes in cellular activity.

    Full Text Available Abstract Background The role of young maternal age as a determinant of adverse child health outcomes is controversial, with existing studies providing conflicting results. This work assessed the association between adolescent childbearing and early offspring mortality in three birth cohort studies from the city of Pelotas in Southern Brazil. Methods All hospital births from 1982 (6,011, 1993 (5,304, and 2004 (4,287 were identified and these infants were followed up. Deaths were monitored through vital registration, visits to hospitals and cemeteries. The analyses were restricted to women younger than 30 years who delivered singletons (72%, 70% and 67% of the original cohorts, respectively. Maternal age was categorized into three groups ( Results There were no interactions between maternal age and cohort year. After adjustment for confounding, pooled ORs for mothers aged 12-19 years were 0.6 (95% CI = 0.4; 1.0 for fetal death, 0.9 (0.6; 1.3 for perinatal death, 1.0 (0.7; 1.6 for early neonatal death, 1.6 (0.7; 3.4 for late neonatal death, 1.8 (1.1; 2.9 for postneonatal death, and 1.6 (1.2; 2.1 for infant death, when compared to mothers aged 20-29 years. Further adjustment for mediating variables led to the disappearance of the excess of postneonatal mortality. The number of mothers younger than 16 years was not sufficient for most analyses. Conclusion The slightly increased odds of postneonatal mortality among children of adolescent mothers suggest that social and environmental factors may be more important than maternal biologic immaturity.

    Sleep problems and symptoms of ADHD are common in adolescence, but detailed epidemiological assessment of their association is lacking. Using data from a recent population-based study, 9,846 adolescents aged 16 to 19 provided detailed information on sleep and symptoms of ADHD. Results confirmed a large overlap between self-reported symptoms of ADHD and all sleep variables studied. Symptoms of ADHD were linked to shorter sleep duration, longer sleep latency, and nocturnal wake time, as well as larger sleep deficiency. ADHD symptoms also increased the odds of insomnia and delayed sleep phase syndrome. The associations were only partially explained by confounders (mainly depression). The findings suggest that sleep problems should be included as a treatment target in efforts to reduce symptoms of ADHD in adolescence. PMID:26503122

    Full Text Available Working memory (WM impairment is a common feature in individuals with schizophrenia and high-risk for psychosis and a promising target for early intervention strategies. However, it is unclear to what extent WM impairment parallels specific behavioral symptoms along the psychosis continuum. To address this issue, the current study investigated the relation of WM capacity with psychotic-like experiences (PLEs in a large Swedish population sample (N = 1012 of adolescents and young adults (M = 24.4 years, range 12-35. WM was assessed with two online computer tasks: A task where participants had to identify and remember the location of an odd shape and a task of remembering and following instructions. PLE scores were derived from a translated symptom questionnaire (Community Assessment of Psychic Experiences; CAPE, which includes positive, negative and depressive symptom scales. Positive and negative symptom scales were further subdivided into symptom clusters based on factor analyses. The results showed that low WM capacity was modestly associated with increased reports of bizarre experiences and depressive symptoms, after controlling for age, gender, and global symptom scores. Interestingly, when analyses were repeated for separate age groups, low WM was exclusively associated with a higher frequency of bizarre experiences for young adults (20 - 27 years and with depressive symptoms for older adults (28 - 35 years. These findings suggest that specific PLEs can be indicative of reduced WM capacity in early adulthood, which in turn may reflect an increased risk for psychosis and a greater need for targeted intervention. In contrast, during adolescence individual differences in cognitive development may influence the strength of the relationships and thereby mask potential vulnerabilities for psychopathology.

    Recent studies suggest that stress can amplify the harm of air pollution. We examined whether experience of racism and exposure to particulate matter with an aerodynamic diameter of less than 2.5 µm and 10 µm (PM2.5 and PM10) had a synergistic influence on ethnic differences in asthma and lung function across adolescence. Analyses using multilevel models showed lower forced expiratory volume (FEV1), forced vital capacity (FVC) and lower rates of asthma among some ethnic minorities compared to Whites, but higher exposure to PM2.5, PM10 and racism. Racism appeared to amplify the relationship between asthma and air pollution for all ethnic groups, but did not explain ethnic differences in respiratory health. PMID:23933797

    Are adolescents who attend schools with a high level of alcohol use and binge drinking more likely to use alcohol and binge drink themselves? This paper analyzes peer effects in adolescent drinking based on a survey of 13,070 adolescents conducted in Sweden in 2005. The empirical analysis uses a multi-level logistic model to account for non-observable heterogeneity between the schools and the results show that attending a school with a high level of alcohol use and frequent binge drinking is a strong predictor of alcohol use and binge drinking for the individual. Hardly any significant interaction effects are detected, implying that peer influence is similar across different adolescent sub-groups. Looking at adolescents with different ethnic backgrounds, it is found that the drinking-pattern of the Swedish majority population has a significant effect on drinking by Swedish individuals and immigrants from Nordic and European countries, but no effect on drinking by immigrants from non-European countries.

    Full Text Available BACKGROUND: Certain population groups have been rendered vulnerable in Chad because of displacement of more than 200,000 people over the last three years as a result of mass violence against civilians in the east of the country. The objective of the study was to assess mortality and nutritional patterns among displaced and non-displaced population living in camps, villages and a town in the Ouddaï and Salamat regions of Chad. METHODOLOGY: Between May and October 2007, two stage, 30-cluster household surveys were conducted among 43,900 internally displaced persons (IDPs living in camps in Ouaddai region (n = 898 households, among 19,400 non-displaced persons (NDPs living in 42 villages in Ouaddai region (n = 900 households and among 17,000 NDPs living in a small town in Salamat region (n = 901 households. Data collection included anthropometric measurements, measles vaccination rates and retrospective mortality. Crude mortality rate (CMR, mortality rate among children younger than 5 years (U5MR, causes of death and the prevalence of wasting (weight-for-height z score <-2 among children aged 6 to 59 months were the main outcome measures. CONCLUSIONS: The CMR among the 4902 IDPs in Gozbeida camps, 4477 NDPs living in a village and 4073 NDPs living in a town surveyed was 1.8 (95% CI, 1.2-2.8, 0.3 (95% CI, 0.2-0.4, 0.3 (95% CI, 0.2-0.5 per 10,000 per day, respectively. The U5MR in a camp (n = 904, a village (n = 956 and a town (n = 901 was 4.1 (95% CI, 2.1-7.7, 0.5 (95% CI, 0.3-0.9 and 0.7 (95% CI, 0.4-1.4 per 10,000 per day, respectively.

    Full Text Available Introduction: The availability of specialized HIV services is limited in rural areas of sub-Saharan Africa where the need is the greatest. Where HIV services are available, people living with HIV (PLHIV must overcome large geographic, economic and social barriers to access healthcare. The objective of this study was to understand the unique barriers PLHIV face when accessing healthcare compared with those not living with HIV in a rural area of sub-Saharan Africa with limited availability of healthcare infrastructure. Methods: We conducted a population-based cross-sectional study of 447 heads of household on Bugala Island, Uganda. Multiple linear regression models were used to compare travel time, cost and distance to access healthcare, and log binomial models were used to test for associations between HIV status and access to nearby health services. Results: PLHIV travelled an additional 1.9 km (95% CI (0.6, 3.2 km, p=0.004 to access healthcare compared with those not living with HIV, and they were 56% less likely to access healthcare at the nearest health facility to their residence, so long as that facility lacked antiretroviral therapy (ART services (aRR=0.44, 95% CI (0.24 to 0.83, p=0.011. We found no evidence that PLHIV travelled further for care if the nearest facility supplies ART services (aRR=0.95, 95% CI (0.86 to 1.05, p=0.328. Among those who reported uptake of care at one of two facilities on the island that provides ART (81% of PLHIV and 68% of HIV-negative individuals, PLHIV tended to seek care at a higher tiered facility that provides ART, even when this facility was not their closest facility (30% of PLHIV travelled further than the closest ART facility compared with 16% of HIV-negative individuals, and travelled an additional 2.2 km (p=0.001 to access that facility, relative to HIV-negative individuals (aRR=1.91, 95% CI (1.00 to 3.65, p=0.05. Among PLHIV, residential distance was associated with access to facilities providing

    Full Text Available Abstract Background Thoracic spine pain (TSP is experienced across the lifespan by healthy individuals and is a common presentation in primary healthcare clinical practice. However, the epidemiological characteristics of TSP are not well documented compared to neck and low back pain. A rigorous evaluation of the prevalence, incidence, correlates and risk factors needs to be undertaken in order for epidemiologic data to be meaningfully used to develop evidence-based prevention and treatment recommendations for TSP. Methods A systematic review method was followed to report the evidence describing prevalence, incidence, associated factors and risk factors for TSP among the general population. Nine electronic databases were systematically searched to identify studies that reported either prevalence, incidence, associated factors (cross-sectional study or risk factors (prospective study for TSP in healthy children, adolescents or adults. Studies were evaluated for level of evidence and method quality. Results Of the 1389 studies identified in the literature, 33 met the inclusion criteria for this systematic review. The mean (SD quality score (out of 15 for the included studies was 10.5 (2.0. TSP prevalence data ranged from 4.0–72.0% (point, 0.5–51.4% (7-day, 1.4–34.8% (1-month, 4.8–7.0% (3-month, 3.5–34.8% (1-year and 15.6–19.5% (lifetime. TSP prevalence varied according to the operational definition of TSP. Prevalence for any TSP ranged from 0.5–23.0%, 15.8–34.8%, 15.0–27.5% and 12.0–31.2% for 7-day, 1-month, 1-year and lifetime periods, respectively. TSP associated with backpack use varied from 6.0–72.0% and 22.9–51.4% for point and 7-day periods, respectively. TSP interfering with school or leisure ranged from 3.5–9.7% for 1-year prevalence. Generally, studies reported a higher prevalence for TSP in child and adolescent populations, and particularly for females. The 1 month, 6 month, 1 year and 25 year incidences were 0

    Full Text Available AIM: Increase in aged population in number brings along the risk of falls and fall-related injuries among elderly. It has been reported that almost 60% of falls occur in nursing homes and majority of admissions to emergency departments due to falls consist of elderly. The purpose of this study conducted in a nursing home in Ankara was to determine the frequency of falls and risk factors, and to clear out the opinions and views of the participants on planning and promoting interventions for prevention. METHOD: This cross-sectional study was carried out among 60 years of age and older residents who lived in a nursing home. Data of the study was collected via face to face interviewing technique. The questionnaire consisted of four sections including socio-demographic characteristics, health status of the participants, healthy/risky behavior and fall related characteristics. RESULTS: Mean age of the 75 female and 59 male participants involved in the study was 73.99+/-7.18. Females were found to fall more in frequency than males (p>0.05. It was found that nearly half of the males (47.5% and more than half of the females (56.0% fell at least once within the previous year. Number of falls were higher among 75 years of age and older participants compared to the other age groups (p=0.003. Compared to the participants with fall background, aged people without fall background gave more correct answers in number to the questions which were asked to assess the knowledge on falls. Six out of 20 answers were statistically significantly correct (p <0.05. CONCLUSION: Individual and environmental interventions to be continued both inside and outside the institutions in order to prevent falls. [TAF Prev Med Bull 2015; 14(1.000: 23-32

    Full Text Available Background: In recent years new applications of technologies, including digital images, to capture dietary behaviour in real time have been explored. Objectives: To validate a digital method for estimating evening meal intake in a free-living adult population, and to examine the feasibility of the method for recording evening meal intake over a prolonged period of time. Design: The digital method was compared against weighed records of 19 participants’ usual evening meals for five consecutive days. Two trained image analysts independently estimated the weight of individual foods within the meals into major food categories, and the nutrient content was calculated. A second study included interviews with 28 participants recording their evening meals on weekdays for three consecutive weeks to get their perspective on the feasibility of the method. Results: High correlation coefficients between the digital method and weighed records were found for all measured food categories and nutrients. Comparable means and acceptable limits of agreement (mean difference +/− 2 SD were found with regard to macronutrient distribution (e.g. fat content −5 to 6 E%, energy density (−75 to 91 kJ/100 g, and energy-adjusted foods (e.g. fruit and vegetable content −241 to 236 g/10 MJ. The majority of the participants expressed satisfaction with the method and were willing to record their evening meals for 1 month or more using the digital method. Conclusion: The digital method is valid and feasible for evening meal estimation in real-time where a prolonged recording period of participants’ meals is needed.

    In cement plants, the substitution of traditional fossil fuels not only allows a reduction of CO(2), but it also means to check-out residual materials, such as sewage sludge or municipal solid wastes (MSW), which should otherwise be disposed somehow/somewhere. In recent months, a cement plant placed in Alcanar (Catalonia, Spain) has been conducting tests to replace fossil fuel by refuse-derived fuel (RDF) from MSW. In July 2009, an operational test was progressively initiated by reaching a maximum of partial substitution of 20% of the required energy. In order to study the influence of the new process, environmental monitoring surveys were performed before and after the RDF implementation. Metals and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were analyzed in soil, herbage, and air samples collected around the facility. In soils, significant decreases of PCDD/F levels, as well as in some metal concentrations were found, while no significant increases in the concentrations of these pollutants were observed. In turn, PM(10) levels remained constant, with a value of 16μgm(-3). In both surveys, the carcinogenic and non-carcinogenic risks derived from exposure to metals and PCDD/Fs for the population living in the vicinity of the facility were within the ranges considered as acceptable according to national and international standards. This means that RDF may be a successful choice in front of classical fossil fuels, being in accordance with the new EU environmental policies, which entail the reduction of CO(2) emissions and the energetic valorization of MSW. However, further long-term environmental studies are necessary to corroborate the harmlessness of RDF, in terms of human health risks. PMID:20709362

Although this fact was not obvious until many such children began to demonstrate secondary emotional disturbances including social withdrawal, social aggression, delinquency, domestic violence and momicide. This discourse describes advances in research and practice of clinical and psycho-neurological for autism spectrum in recent years. In addition, I suggest policies and measures for therapeutic education that will avoid secondary symptoms allowing these individuals to conduct their lives in socially independent directions.

    International Nuclear Information System (INIS)

    Considerable variations in the frequency of spontaneous chromosomal aberrations were revealed during a cytogenetic study of two groups of adolescents from ecologically different areas of Kemerovskaya oblast'. In a sample of adolescents living in an industrial center (the Kemerovo city), this parameter (1.4±0.37%) did not exceed the population average value, whereas adolescents of the same age from a mountain region with sparse industry (the town of Tashtagol) exhibited, on average, a frequency of 5.87±0.62%. An increased proportion of chromosomal-type aberrations in the qualitative spectrum of cytogenetic damage, which was observed for the group of adolescents from Tashtagol, suggests that this population was exposed to radiation. 13 refS., 1 fig., 3 tabs

Youth and adolescents from key populations or young key populations (YKP in particular are highly stigmatized and may face additional barrier(s in adhering to HIV treatment and services. We reviewed the current knowledge on treatment adherence and retention in HIV care among YKP to identify gaps in the literature and suggest future directions to improve HIV care for YKP. Methods: We conducted a comprehensive literature search for YKP and their adherence to antiretroviral therapy (ART and retention in HIV care on PsycInfo (Ovid, PubMed and Google Scholar using combinations of the keywords HIV/AIDS, ART, adolescents, young adults, adherence (or compliance, retention, men who have sex with men, transgender, injection drug users, people who inject drugs and prisoners. We included empirical studies on key populations defined by WHO; included the terms youth and adolescents and/or aged between 10 and 24; examined adherence to or retention in HIV care; and published in English-language journals. All articles were coded using NVivo. Results and discussion: The systematic search yielded 10 articles on YKP and 16 articles on behaviourally infected youth and adolescents from 1999 to 2014. We found no studies reporting on youth and adolescents identified as sex workers, transgender people and prisoners. From existing literature, adherence to ART was reported to be influenced by age, access to healthcare, the burden of multiple vulnerabilities, policy involving risk behaviours and mental health. A combination of two or more of these factors negatively impacted adherence to ART among YKP. Collectively, these studies demonstrated that future programmes need to be tailored specifically to YKP to ensure adherence. Conclusions: There is

    Full Text Available Background: Petrochemical industry emits air pollutants in abundance, which may harm human health, especially the population living near the industry. Children are reported to be the population group of main concern since this susceptible population spends the majority of their time outdoors and their active lifestyle can increase their breathing rate, which then leads to a greater inhalation dose of air pollutants and greater risk of health effects.Method: The materials for this review were obtained from several on-line databases such as PubMed, Proquest, Scopus and Science Direct (year 1990-2015. In this review, we highlighted several relevant studies on respiratory health effects from petrochemical air pollutant exposure among children living in the neighborhood and highlighted the factors, which contributed to the severity of the health outcomes.Results: Short term petrochemical air pollutant exposure increases respiratory symptom, reduces lung function and incidence of asthma especially for those who living within 5 km radius from the industry.Conclusion: This review will provide a compilation of potential respiratory health outcomes that arises from the inhalation of petrochemical air pollutants among children. Keywords: Petrochemical industry, Respiratory health effects, Children

    The removal of eggs or chicks from wild populations to create captive populations, reinforce free-ranging populations or reintroduce species into the wild is a restoration tool that requires an assessment of potential detrimental effects upon the donor population. This is an absolute prerequisite when wild donor populations are scarce and small. Here, we forecast the population trend of the largest European population of the bearded vulture (Gypaetus barbatus) over the next 30 years under different demographic and management scenarios (removal of eggs, chicks or fledglings). Projections derived from the combination of a PDP model (Population Dynamic P-system) and a Box-Behnken design would lead to a decline in 77% of all 57 scenarios analysed. Among the 13 scenarios predicting a population increase, only 4 seem realistic in terms of growth rate (0.04%-1.01%), at least if current age at first breeding and productivity would remain constant over time. Our simulations thus suggest that most extraction scenarios would have detrimental effects on the demography of the donor population. Release of captive-born young or removal of only the second hatched chick for subsequent captive rearing and translocation into the wild appear to represent much better supplementation and reintroduction options in this threatened species.

    Full Text Available We present a novel method for conducting requirements gathering with adolescent populations. Called videographic requirements gathering, this technique makes use of mobile phone data capture and participant creation of media images. The videographic requirements gathering method can help researchers and designers gain intimate insight into adolescent lives while simultaneously reducing power imbalances. We provide rationale for this approach, pragmatics of using the method, and advice on overcoming common challenges facing researchers and designers relying on this technique.

    To evaluate the consistency of the relationship between early drug use in adolescence and illegal drug use in adulthood as proposed in the "gateway theory" and to determine whether pre-existing depressive symptoms modifies this relationship. We used contractual data from the National Longitudinal Study of Adolescent to Adult health data spanning a 14 year period. We assessed the relationship between gateway drugs at baseline (age 11-20 years) and drug use in adulthood using generalized estimating equation (GEE) regression models. Gateways drugs used in early adolescence were significantly associated with marijuana use, illegal drugs and cocaine in older adolescence, but over time these relationships were not consistent in adulthood. Changes in the pattern of psychoactive drug use were important predictors of drug use in adulthood. A history of higher depressive symptoms was associated with higher frequencies of psychoactive drug use over time. Users of mental health services in adolescence were less likely to use drugs in older adolescence and in adulthood. Relationships between early drug use and later drug use in adulthood cannot be solely explained by the gateway hypothesis. Collectively, adolescent drug prevention and treatment programs should apply theory-based and evidence-proven multisectoral intervention strategies rather than providing a brief counseling on individual's behaviors. This evidence should include understanding that changes in behavior should involve broader analyses of the underlying social context for drug use and in particular the role of the community social norms in driving a group's behaviors.

    Full Text Available Abstract Background Attention-Deficit/Hyperactivity Disorder (ADHD is the most common chronic mental health condition in children and adolescents. The application of health-related quality of life (HRQOL as a pediatric population health measure may facilitate risk assessment and resource allocation, the identification of health disparities, and the determination of health outcomes from interventions and policy decisions for children and adolescents with ADHD at the local community, state, and national health level. Methods An analysis from an existing statewide database to determine the feasibility, reliability, and validity of the 23-item PedsQL™ 4.0 (Pediatric Quality of Life Inventory™ Generic Core Scales as a patient-reported outcome (PRO measure of pediatric population health for children and adolescents with ADHD. The PedsQL™ 4.0 Generic Core Scales (Physical, Emotional, Social, School Functioning were completed by families through a statewide mail survey to evaluate the HRQOL of new enrollees in the State of California State's Children's Health Insurance Program (SCHIP. Seventy-two children ages 5–16 self-reported their HRQOL. Results The PedsQL™ 4.0 evidenced minimal missing responses, achieved excellent reliability for the Total Scale Score (α = 0.92 child self-report, 0.92 parent proxy-report, and distinguished between healthy children and children with ADHD. Children with ADHD self-reported severely impaired psychosocial functioning, comparable to children with newly-diagnosed cancer and children with cerebral palsy. Conclusion The results suggest that population health monitoring may identify children with ADHD at risk for adverse HRQOL. The implications of measuring pediatric HRQOL for evaluating the population health outcomes of children with ADHD internationally are discussed.

    2016-01-01

    Objective: To describe incidence patterns and trends in children (0-14 years) and adolescents (15-19 age-range) with solid tumours, except those of central nervous system (CNS), in Spain. Methods: Cases were drawn from eleven Spanish population-based cancer registries. Incidence was estimated for the period 1983-2007 and trends were evaluated using Joinpoint regression analysis. Results: The studied tumour groups accounted for 36% of total childhood cancers and 47.6% of those diagnosed in adolescence with annual rates per million of 53.5 and 89.3 respectively. In children 0 to 14 years of age, Neuroblastoma (NB) was the commonest (7.8%) followed by Soft-tissue sarcomas (STS) (6.3%), bone tumours (BT) (6.2%) and renal tumours (RT) (4.5%). NB was the most frequently diagnosed tumour before the 5th birthday, while STS and BT were the commonest at 5-9 years of age, and BT and Carcinoma and other epithelial tumours (COET) at 10-14. COET presented the highest incidence in adolescents, followed by germ-cell tumours (GCT), BT and STS. These four diagnostic groups accounted for 94% of total non-CNS solid tumours, in adolescents. Overall incidence rates increased significantly in children up to 1996 with an annual percentage change (APC) of 2.6% (95%CI: 1.7; 3.6). NB and COET showed significant time trend (APCs: 1.4% and 3.8% respectively) while other tumour groups such as RT, STS, BT or GCT had no significant changes over time. A significant increase was present in NB under the age of 5 and in BT and STS in children aged 10-14 years. In adolescents there were significant increases for all tumours combined (APC=2.7; 95%CI: 1.8-3.6) and for STS, GCT and COET (APCs: 3.2%, 4.4% and 3.5% respectively), while other tumour groups such as hepatic tumours, BT or thyroid carcinomas showed a decreasing trend or no increase. Conclusions: Overall, the incidence of the studied cancers in children increased along the period 1983-1996 with no posterior significant rise, while the incidence

    Full Text Available Background: Even though vitamin D is mainly produced by exposure to sunlight, little is known regarding vitamin D levels in populations living in sub-Arctic areas with little or no daylight during winter. Objective: We describe distributions of vitamin D3 and the prevalence of adequate levels in a population living above 63°N. Design: We sampled 1,622 randomly selected subjects, aged 25–74 years, between January and May, 2009, as part of the Northern Sweden MONICA study (69.2% participation rate. By using HPLC, 25(OH vitamin D3 was analysed. Levels used for definitions were deficient, D3<25 nmol/l (<10 ng/ml; insufficient, D3 25–49.9 nmol/l (10–20 ng/ml; and adequate, D3≥50 nmol/l (20 ng/ml. Results: Mean (median level of vitamin D3 was 65.2 (63.6 nmol/l in men and 71.0 (67.7 nmol/l in women. Adequate levels were found in 79.2%, more often in women (82.7% than in men (75.6%. Only 0.7% of the population were vitamin D3–deficient but 23.1% of men and 17.1% of women had insufficient levels. Levels of vitamin D3 increased with age and insufficient status was most common among those aged 25–34 years, 41.0% in men and 22.3% in women.If subjects using vitamin D-supplementation are excluded, the population level of D3 is 1–2 nmol/l lower than in the general population across sex- and age groups. There were no differences between the northern or the southern parts, between urban or rural living or according to educational attainment. Those subjects born outside of Sweden or Finland had lower levels. Conclusion: The large majority living close to the Arctic Circle in Sweden have adequate D3 levels even during the second half of the dark winter. Subjects with D3 deficiency were uncommon but insufficient levels were often found among young men.

    Effective population size (N(e)) is a key parameter for monitoring the genetic health of threatened populations because it reflects a population's evolutionary potential and risk of extinction due to genetic stochasticity. However, its application to wildlife monitoring has been limited because it is difficult to measure in natural populations. The isolated and well-studied population of grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem provides a rare opportunity to examine the usefulness of different N(e) estimators for monitoring. We genotyped 729 Yellowstone grizzly bears using 20 microsatellites and applied three single-sample estimators to examine contemporary trends in generation interval (GI), effective number of breeders (N(b)) and N(e) during 1982-2007. We also used multisample methods to estimate variance (N(eV)) and inbreeding N(e) (N(eI)). Single-sample estimates revealed positive trajectories, with over a fourfold increase in N(e) (≈100 to 450) and near doubling of the GI (≈8 to 14) from the 1980s to 2000s. N(eV) (240-319) and N(eI) (256) were comparable with the harmonic mean single-sample N(e) (213) over the time period. Reanalysing historical data, we found N(eV) increased from ≈80 in the 1910s-1960s to ≈280 in the contemporary population. The estimated ratio of effective to total census size (N(e) /N(c)) was stable and high (0.42-0.66) compared to previous brown bear studies. These results support independent demographic evidence for Yellowstone grizzly bear population growth since the 1980s. They further demonstrate how genetic monitoring of N(e) can complement demographic-based monitoring of N(c) and vital rates, providing a valuable tool for wildlife managers. PMID:26510936

    1994-05-01

    Adolescence is a phase of human development which is marked by a high vulnerability due to the ongoing psycho-physiological transformations. The regulation of the self-esteem is especially in danger in youngsters who went into adolescence with a marked burden of conflicts or who lived in families with disturbed intrafamilial dynamics. To be present as a partner and not to find the solutions for the adolescents' conflicts, to accept their questioning of what is established and to recognize their movements of reconciliation are the quite complex demands put on to the world of the adults. Adolescents urge us to a review of our own adolescence, to a balancing of hate and love, openness and rigidity, and to dialectic movements between disintegration and reintegration as well as between the generations. Any help, be it on the physical, the social or the psychic level, should be directed toward a restitution of the intrapsychic, intrafamilial or intergenerational balance; sociocultural factors have also always to be respected. The helpers--especially in a culture with rapid change--are often confronted with their own adolescence, which took place a generation before and mostly under totally different conditions.

There has been a lack of evaluation tools able to take account of the more holistic approach to the attainment of mental health that characterises Māori, the Indigenous population of Aotearoa (New Zealand. This study aimed to develop such an instrument and establish some of its psychometric properties. Then, to use the measure to establish whānau (family or caregiver views on desirable CAMHS characteristics.MethodA self-administered survey, Te Tomokanga, was developed by modifying a North American questionnaire, the Youth Services Survey for Families (YSS-F. The intent of the tool was to record whānau experiences and views on service acceptability.The Te Tomokanga survey is unique in that it incorporates questions designed to examine CAMHS delivery in light of the Whare Tapa Whā[1], a Māori comprehensive model of health with a focus on whānau involvement and culturally responsive services. This mail or telephone survey was completed by a cohort of 168 Māori whānau. Their children had been referred to one of the three types of CAMHS, mainstream, bicultural, and kaupapa Māori[2], of the District Health Board (DHBs in the Midland health region, Aotearoa. The Midland health region is an area with a large Māori population with high levels of social deprivation.ResultsThe Te Tomokanga instrument was shown to have a similar factor structure to the North American questionnaire from which it had been derived. It identified issues relevant to Māori whānau satisfaction with CAMHS. The work supports the concept that Māori desire therapeutic methods consistent with the Whare Tapa Whā, such as whānau involvement and the importance of recognising culture and spirituality.The participants were generally positive about the services they received from the three different CAMHS types, which shows good acceptability of CAMHS for

    2012-01-01

    Current life history theory suggests that the allocation of energetic resources between competing physiological needs should be dictated by an individual's longevity and pace of life. One key physiological pathway likely to contribute to the partitioning of resources is the vertebrate stress response. By increasing circulating glucocorticoids the stress response can exert a suite of physiological effects, such as altering immune function. We investigated the effects of stress physiology on individual immunity, reproduction and oxidative stress, across an urban landscape. We sampled populations in and around St. George, Utah, examining corticosterone in response to restraint stress, two innate immune measures, reproductive output, and the presence of both reactive oxygen metabolites and antioxidant binding capacity, in populations of common side-blotched lizards (Uta stansburiana) experiencing variable levels of environmental stress. Additionally, using capture-mark-recapture techniques, we examined the relationships between these physiological parameters and population-level differences. Our results reveal elevated physiological stress corresponds with suppressed immunity and increased oxidative stress. Interestingly, urban populations experiencing the most physiological stress also exhibited greater reproductive output and decreased survival relative to rural populations experiencing less physiological stress, demonstrating a tradeoff between reproduction and life maintenance processes. Our results suggest that environmental stress may augment life history strategy in this fast-paced species, and that shifts in life history strategy can in turn affect the population at large. Finally, the urban environment poses definite challenges for organisms, and while it appears that side-blotched lizards are adjusting physiologically, it is unknown what fitness costs these physiological adjustments accrue.

    2009-01-01

    Physiological theories may be important in the development and maintenance of social phobia in youth. A limited literature base indicates that youth with social phobia experience increases in objective physiological arousal during social-evaluative situations and are more aware of such increases compared to nonanxious youth. Recent research suggests that youth with social phobia also evidence heightened levels of anxiety sensitivity, which may lead to interpretation of physiological arousal as dangerous or distressing, and, as a result, in avoidance of situations which produce increased physiological arousal. The purpose of the current study was to examine interaction among objective physiological arousal, perceived physiological arousal, and anxiety sensitivity among adolescents diagnosed with social phobia. A sample of community adolescents participated in two anxiety-provoking tasks during which objective physiological arousal was monitored, and after which perceived physiological arousal and anxiety sensitivity were evaluated. Results from this study evidenced no differences between social phobic and nonanxious adolescents with regard to objective physiological arousal during either anxiety-provoking tasks. Adolescents with social phobia, however, were more aware of measured increases in physiological arousal, as well as more afraid of the potential social implications of that arousal compared to nonanxious adolescents. Implications for theory and treatment are discussed. PMID:18436426

    Full Text Available Abstract Background The KIDSCREEN-52 is a worldwide instrument for measuring health-related quality of life (HRQoL in children and adolescents. The aim of this study is to assess reliability and validity of the Greek version of KIDSCREEN. Methods Questionnaires were collected from a representative nationwide sample of 1,194 adolescents aged from 11 to 17 years. Internal consistency reliability was determined by calculation of the Cronbach α coefficient. A confirmatory factor analysis (CFA was conducted in order to test the construct validity of the questionnaire. Validity was further examined by investigating the correlation of KIDSCREEN with the Strengths and Difficulties Questionnaire (SDQ and its association with socioeconomic and health-related factors. Results Internal consistency reliability was accepted with a Cronbach α above 0.73 for all KIDSCREEN dimensions. CFA showed that the ten-dimensional model fitted the data well (root mean square error of approximation (RMSEA = 0.048, comparative fit index (CFI = 0.971 and goodness of fit index (GFI = 0.965. Correlation coefficients between KIDSCREEN and SDQ dimensions were significant. Adolescents of low socioeconomic status reported lower scores in the majority of KIDSCREEN dimensions. Also, adolescents with chronic health problem had poorer quality of life concerning physical well-being and other dimensions of KIDSCREEN. Conclusions The Greek version of KIDSCREEN-52 was found to have satisfied psychometric properties and could be suitable for assessing HRQoL in Greek adolescents.

    In order to assess the reference values for selenium nutritional status, adequate indicators (selenium concentration and glutathione peroxidase activity) were determined in whole blood and blood derivates of a healthy population (n = 287) from the province of Valencia, Spain. The reference population was selected by applying preestablished criteria. Selenium in whole blood and plasma was measured by graphite furnace atomic absorption spectrometry (GFAAS), with a deuterium correction, after addition of Pd/Mg(NO3)2 as the matrix modifier and appropriate dilution. Accuracy was checked by means of a reference material (Seronorm Trace Metals serum and whole blood). The population's reference intervals for selenium content at a 95% confidence level were: 53.03-108.96 and 66.71-119.4 mg/L for plasma and whole blood selenium concentration respectively. GPX activity was measured using a modification of the Paglia and Valentine method, and the reference intervals obtained ranged from 196 to 477 U/L in plasma, from 49 to 93 U/gHb in erythrocytes and from 52 to 96 U/gHb in whole blood. The only statistically significant differences detected between men and women are for to the GPX activity in whole blood. The results obtained are in the range of values found by others authors in healthy populations residing in different European countries. PMID:9021673

  1. A programme for exposure and epidemiological surveillance of populations living in the vicinity of industrial waste dumps in France

    International Nuclear Information System (INIS)

    Following the environmental contamination at the industrial waste site of Montchain, the government of France has resolved to sponsor a programme for monitoring the impact of industrial waste dumps on the environment and on the health of neighbouring populations. The epidemiological approach is generally limited in its power to quantify risks and even to identify hazards because of: 1. the usual lack of information on the identify and level of toxic substances in the dump itself, on the exposures of individuals in the vicinity and therefore on the diseases and symptoms to be studied; 2. the relatively small size of the populations 'at risk' of exposure. The proposed solution is to carry out a systematic - prospective - surveillance of specific exposures in, and around, every industrial waste site in activity in France. The surveillance will be tailored to each dump. This will yield much needed information on the distribution and temporal pattern of exposures in the population. Risk projection models can then be applied and ranges of risk estimates derived in order that public authorities can make decisions on the operation of the dump. A health risk information campaign will be set up. A prospective epidemiologic study of dump workers, involving exposure monitoring, and biological and clinical follow-up, will also be set up. Subsequently, and depending on the agents and levels of exposure identified at individual dumps, epidemiologic surveillance of high risk groups (pregnant women, children) and biological monitoring of a subsample of the population may be set up

    study is to gain a deeper insight into the etiology of low back pain and to possibly develop a tool for early identification of high-risk groups. This is done by investigating whether different types of morbidity in adolescence are associated with LBP in adulthood. METHODS: Almost 10,000 Danish twins......BACKGROUND: It has previously been shown that low back pain (LBP) often presents already in the teenage years and that previous LBP predicts future LBP. It is also well documented that there is a large degree of comorbidity associated with LBP, both in adolescents and adults. The objective of this...... predictor variables used in this study were LBP, headache, asthma and atopic disease at baseline; the outcome variable was persistent LBP (>30 days during the past year) at follow-up. Associations between morbidity in 1994 and LBP in 2002 were investigated. RESULTS: LBP, headache and asthma in adolescence...

    The World Health Organization considers adolescence to be the period between 10 and 20 years during which individuals undergo significant psychosexual and psychosocial development. The needs an well-being of people, especially girls, in this age group in India, however, are neglected. Almost 25% of India's population is comprised of girls below 20 years of age. Adolescent pregnancies make up 10-15% of the total and may be largely attributed to early marriage, but these girls are prepared neither physically nor emotionally for pregnancy and motherhood. Adolescents who marry between aged 15-19 will nonetheless bear on average 6-7 children over the course of their lives. In fact, 80% of women's time between the ages 15 and 35 is spent either being pregnant or nursing offspring. Sections discuss nutritional deprivation and poor fetal growth, obstetric risks, and maternal and infant mortality, literacy and school dropouts, and psychosocial aspects of adolescent pregnancy and motherhood. Intervention programs could aim to increase total food intake, prevent against iron deficiency anemia, provide education and health care for girls aged 10-15, promote the use of contraception, register marriages and provide family life education, and involve boys in the education process. While the marriage age needs to be increased, this change should not be legislated. Change must instead result from education syllabi at the school level. PMID:12287001

    Full Text Available Abstract Background Use of electronic media, i.e. mobile phones, computers, television, game consoles or listening to music, is very common, especially amongst adolescents. There is currently a debate about whether frequent use of these media might have adverse effects on health, especially on headaches, which are among the most-reported health complaints in adolescents. The aim of the present study was to assess associations between frequent use of electronic media and the prevalence of different types of headache in adolescents. Methods Data were derived from a population-based sample (n = 1,025, ages 13-17 years. Type of headache (i.e. migraine, tension-type headache, unclassifiable headache was ascertained by standardized questionnaires for subjects reporting headache episodes at least once per month during the last six months. Duration of electronic media use was assessed during personal interviews. Associations were estimated with logistic regression models adjusted for age group, sex, family condition and socio-economic status. Results Most of the adolescents used computers (85%, watched television (90% or listened to music (90% daily, otherwise only 23% of the participants used their mobile phones and only 25% played with game consoles on a daily basis. A statistically significant association between listening to music and any headache (odds ratio 1.8; 95% confidence interval 1.1-3.1 for 30 minutes per day, 2.1; 1.2-3.7 for 1 to 2 hours per day; 2.0; 1.2-3.5 for 3 hours and longer listening to music per day was observed. When stratifying for type of headache, no statistically significant association was seen. Conclusions Apart from an association between listening to music on a daily basis and overall headache, no consistent associations between the use of electronic media and different types of headache were observed.

    Full Text Available Abstract Background The increase in numbers of mobile phone users was accompanied by some concern that exposure to radiofrequency electromagnetic fields (RF EMF might adversely affect acute health especially in children and adolescents. The authors investigated this potential association using personal dosimeters. Methods A 24-hour exposure profile of 1484 children and 1508 adolescents was generated in a population-based cross-sectional study in Germany between 2006 and 2008 (participation 52%. Personal interview data on socio-demographic characteristics, self-reported exposure and potential confounders were collected. Acute symptoms were assessed twice during the study day using a symptom diary. Results Only few of the large number of investigated associations were found to be statistically significant. At noon, adolescents with a measured exposure in the highest quartile during morning hours reported a statistically significant higher intensity of headache (Odd Ratio: 1.50; 95% confidence interval: 1.03, 2.19. At bedtime, adolescents with a measured exposure in the highest quartile during afternoon hours reported a statistically significant higher intensity of irritation in the evening (4th quartile 1.79; 1.23, 2.61, while children reported a statistically significant higher intensity of concentration problems (4th quartile 1.55; 1.02, 2.33. Conclusions We observed few statistically significant results which are not consistent over the two time points. Furthermore, when the 10% of the participants with the highest exposure are taken into consideration the significant results of the main analysis could not be confirmed. Based on the pattern of these results, we assume that the few observed significant associations are not causal but rather occurred by chance.

  6. Health indices of the rural population living in the area affected by the Krasnoyarsk mining and chemical combine

    International Nuclear Information System (INIS)

    Radioactive contamination of the floodplain of the Yenisei River with the wastes dumped by the Krasnoyarsk Mining, and Chemical Combine (MCC) might cause external and internal irradiation of a large part of rural population inhabiting the banks of the Yenisei. Due the lack of comprehensive data on the dose status and doses received by the population, the health parameters of the population were studied by comparing the recorded incidences of diseases and mortality in the areas located at different distances from the MCC, in the periods before and after the MCC was put into operation, and in different age groups. Also studied were territorial differences in the immunologic and immunogenetic statuses of some groups of population. It has been found out that in the district subjected to radioactive contamination (RAC-districts) there are characteristic shifts in the pathologies that are the main markers of the radiation factor. With possible accumulation of radiation doses the shifts become more distinct, and with the distance from the MCC less distinct. Time and space gradients of the cancer morbidity and mortality rate in the RAC-area have been found. In the riverside settlements of the RAC-area the mortality from malignant neoplasms (MN) of blood, blood-forming organs, and lymphatic system is higher than in the settlements located farther from the Yenisei. As the distance from the MCC down the Yenisei gets longer, the mortality of children due to congenital developmental defects and leukaemia decreases. The space gradient has been also found for most somatic disorders originating from stressogenic (psycho-emotional strain) and immunodeficient states. Besides increased incidence of cancer, in the RAC-area there is a higher incidence of pathological states determined to a large extent genetically - complicated pregnancies and their outcome, mortinatality, and congenital developmental defects.

    Full Text Available Abstract Background Undocumented immigrants are likely to be missing from population databases, making it impossible to identify an accurate sampling frame in migration research. No population-based data has been collected in Chile regarding the living conditions and health status of undocumented immigrants. However, the CASEN survey (Caracterizacion Socio- Economica Nacional asked about migration status in Chile for the first time in 2006 and provides an opportunity to set the base for future analysis of available migration data. We explored the living conditions and health of self-reported immigrants and respondents who preferred not to report their migration status in this survey. Methods Cross-sectional secondary analysis of CASEN survey in Chile in 2006. Outcomes: any disability, illness/accident, hospitalization/surgery, cancer/chronic condition (all binary variables; and the number of medical/emergency attentions received (count variables. Covariates: Demographics (age, sex, marital status, urban/rural, ethnicity, socioeconomic status (education level, employment status and household income, and material standard of living (overcrowding, sanitation, housing quality. Weighted regression models were estimated for each health outcome, crude and adjusted by sets of covariates, in STATA 10.0. Results About 1% of the total sample reported being immigrants and 0.7% preferred not to report their migration status (Migration Status - Missing Values; MS-MV. The MS-MV lived in more deprived conditions and reported a higher rate of health problems than immigrants. Some gender differences were observed by health status among immigrants and the MS-MV but they were not statistically significant. Regressions indicated that age, sex, SES and material factors consistently affected MS-MVs’ chance of presenting poor health and these patterns were different to those found among immigrants. Great heterogeneity in both the MS-MV and the immigrants, as

    To investigate the association of the hygiene index values of live fresh aquatic products and food-borne diarrhea in the population of the Ningbo area in China. Volatile basic nitrogen (VBN), histamine (HIS), indole, tetrodotoxin (TTX), and paralytic, neurotoxic, amnesic and diarrhetic shellfish poisons (PSP, NSP, ASP, and DSP, respectively) in the samples of live fresh aquatic products and food-borne diarrhea cases in six studied districts were analyzed. Results indicate that the incidence rate of food-borne diarrhea is related to the hygiene index values. Aside from VBN, the main risk factors related to food-borne diarrhea in edible aquatic products include DSP (in marine fish, shrimp, and other shellfishes), NSP, and ASP (in marine shrimp and crab). Hygiene index values among different species were significantly different. No significant difference in the monitoring index values was found among the six different studied districts. The reported cases of food-borne diarrhea were positively associated with VBN and DSP in aquatic products in Haishu, Jiangbei, Zhenhai, and Beilun, as well as VBN and NSP in aquatic products in Jiangdong and Yinzhou. In conclusion, VBN, DSP, NSP, and ASP are important risk factors for the occurring of food-borne diarrhea in the population of the Ningbo area in China. PMID:26258783

  12. Reconstruction of radiation dose distribution of the village population living in territories contaminated after the Chernobyl NPP accident

    International Nuclear Information System (INIS)

    Correct assessment and prediction of doses in population is one of the most actual and complex problems of radiation medicine. Apparently great amount of models has been developed so far to evaluate average doses. But for the actual (real) doses estimation within a settlement this is not enough: it is necessary to estimate distribution on the whole, as the accuracy of these models is insufficient and the application of the above models does not answer the designed tasks. At the same time decision support strategies of countermeasures application are always based on the prediction of doses received in the areas affected by contamination. The original method for estimation of the external and, than, the total doses distributions on the known internal dose distribution is presented. This method is based on the hypothesis of the genetic relationship between the external and internal doses, received in rural inhabitants, because the representatives of the separate population groups demonstrate similar 'behaviour' in the radiation field. Algorithm of the task is to recognize the population groups of similarity in the settlement on the basis of the informative factors (method of classification). The method proves that the close relationship between external and internal doses exists, but only - within classes of similarity. The external dose distribution in the inhabitants of Kirov town was reconstructed. The comparison of this distribution with the distribution, received using TLD, shows that they are very close in terms of statistical parameters. The total dose distribution was received for inhabitants of the Kirov settlement using measured internal doses and predicted external doses with the following evaluation of its parameters. Proposed method allows to optimize and to increase the correctness (the error does not exceed 30% ) of the evaluation of doses in the rural population. (authors)

    Full Text Available Abstract Background The Tarim Basin, located on the ancient Silk Road, played a very important role in the history of human migration and cultural communications between the West and the East. However, both the exact period at which the relevant events occurred and the origins of the people in the area remain very obscure. In this paper, we present data from the analyses of both Y chromosomal and mitochondrial DNA (mtDNA derived from human remains excavated from the Xiaohe cemetery, the oldest archeological site with human remains discovered in the Tarim Basin thus far. Results Mitochondrial DNA analysis showed that the Xiaohe people carried both the East Eurasian haplogroup (C and the West Eurasian haplogroups (H and K, whereas Y chromosomal DNA analysis revealed only the West Eurasian haplogroup R1a1a in the male individuals. Conclusion Our results demonstrated that the Xiaohe people were an admixture from populations originating from both the West and the East, implying that the Tarim Basin had been occupied by an admixed population since the early Bronze Age. To our knowledge, this is the earliest genetic evidence of an admixed population settled in the Tarim Basin.

    To understand the evolutionary histories and conservation potential of wild animal species it is useful to assess whether taxa are genetically structured into different populations and identify the underlying factors responsible for any clustering. Landscape features such as rivers may influence genetic population structure, and analysis of structure by sex can further reveal effects of sex-specific dispersal. Using microsatellite genotypes obtained from noninvasively collected fecal samples we investigated the population structure of 261 western lowland gorillas (WLGs) (Gorilla gorilla gorilla) from seven locations spanning an approximately 37,000 km(2) region of mainly continuous rain forest within Central African Republic (CAR), Republic of Congo and Cameroon. We found our sample to consist of two or three significantly differentiated clusters. The boundaries of the clusters coincided with courses of major rivers. Moreover, geographic distance detoured around rivers better-explained variation in genetic distance than straight line distance. Together these results suggest that major rivers in our study area play an important role in directing WLG gene flow. The number of clusters did not change when males and females were analyzed separately, indicating a lack of greater philopatry in WLG females than males at this scale. PMID:24700547

    There are few studies on psychosocial problems in adolescents with eczema. We performed a cross-sectional, questionnaire-based study to explore the relationship of suicidal ideation, mental health problems, and social functioning with eczema. A total of 4,744 adolescents (18-19 years) were invited for the study, of whom 3,775 (80%) participated. The overall prevalence of current eczema was 9.7%. Among those with current eczema, 15.5% reported suicidal ideation compared with 9.1% among those without eczema, significantly associated in a multivariate model (odds ratio 1.87, 95% confidence interval 1.31-2.68). In a subgroup analyses, the prevalence of suicidal ideation in those with both eczema and itch was 23.8%, and was significantly associated, compared with those without eczema (3.57, 2.46-5.67). Eczema was associated with mental health problems assessed by the Strength and Difficulties Questionnaire (1.72, 1.21-2.45) and the Hopkins Symptom Checklist 10 (1.63, 1.23-2.16). Five questions assessed social function: feeling attached to family and friends; thriving at school; experiencing bullying; and romantic relationships. Boys with current eczema were less likely to have had romantic relationships (1.93, 1.21-3.08). Eczema in late adolescence is associated with suicidal ideation and mental health problems but rarely with social problems. Our findings point to the importance of addressing mental health issues in adolescents with eczema. PMID:24496238

  3. Thyroid nodules in the population living around semipalatinsk nuclear test site. Possible implications for dose-response relationships study

    International Nuclear Information System (INIS)

    The risk of radiation-induced nodules is higher than the risk for radiation-induced cancer. Risk factors and specific modifiers of the dose-response relationship may vary among different populations and not be well recognized. Many thyroid studies have considered thyroid nodularity itself, but not specific morphological types of thyroid nodules. There are many specific types of thyroid nodules which follow a morphological classification of thyroid lesions, including some congenital and tumor-like conditions. Modern equipment and technique can help us to identify particular specific types of thyroid nodules. In this study we report some results of a clinically applicable approach to materials derived from three studies. From 1999 through 2002, we have screened 571 current residents from 4 exposed and 1 control village near the Semipalatinsk Nuclear Test Site area, who were of similar ages (<20) at the time of major radiation fallout events at the Semipalatinsk Nuclear Test Site (SNTS). Prevalent nodules were identified by ultrasound and fine-needle aspiration biopsy, cytopathology results. Analysis of ultrasound images and cytopathology of thyroid lesions among exposed and non-exposed population allowed us to distinguish some interesting ultrasound features for specific types of thyroid nodules. We believe that it would be interesting and possibly more informative for thyroid dosimetry studies to consider specific morphological types of thyroid nodules. We need more detailed research to clarify the feasibility of applying these findings for study of the dose-response relationship. (author)

  4. Label-free detection of neuronal differentiation in cell populations using high-throughput live-cell imaging of PC12 cells.

    Directory of Open Access Journals (Sweden)

    Sebastian Weber

    Full Text Available Detection of neuronal cell differentiation is essential to study cell fate decisions under various stimuli and/or environmental conditions. Many tools exist that quantify differentiation by neurite length measurements of single cells. However, quantification of differentiation in whole cell populations remains elusive so far. Because such populations can consist of both proliferating and differentiating cells, the task to assess the overall differentiation status is not trivial and requires a high-throughput, fully automated approach to analyze sufficient data for a statistically significant discrimination to determine cell differentiation. We address the problem of detecting differentiation in a mixed population of proliferating and differentiating cells over time by supervised classification. Using nerve growth factor induced differentiation of PC12 cells, we monitor the changes in cell morphology over 6 days by phase-contrast live-cell imaging. For general applicability, the classification procedure starts out with many features to identify those that maximize discrimination of differentiated and undifferentiated cells and to eliminate features sensitive to systematic measurement artifacts. The resulting image analysis determines the optimal post treatment day for training and achieves a near perfect classification of differentiation, which we confirmed in technically and biologically independent as well as differently designed experiments. Our approach allows to monitor neuronal cell populations repeatedly over days without any interference. It requires only an initial calibration and training step and is thereafter capable to discriminate further experiments. In conclusion, this enables long-term, large-scale studies of cell populations with minimized costs and efforts for detecting effects of external manipulation of neuronal cell differentiation.

    Studies of subjective perception of the radiation situation, self-estimation of the health status by the population, the attitude of the population to the formal information available were carried out in the strong radiation control areas and in the regions not polluted by radioactive fallout. Before the accident 71.6% of the population were not aware of real danger of radiation for health. During the accident and after it, mass media were the main source of information on the consequences of the accident and the effect of radiation (71.1%). 38% of the information was provided by scientists and specialists. 89.6% of the persons interviewed experience anxiety whatever the intelligence available. Only 13.4% of those who live in the areas polluted by radionuclides feel well. The low self-estimation of the health status, the high level of anxiety together with the deficiency of radiation and hygienic intelligence favour the forcing of the social and psychological tension and reduce the effectiveness of the whole complex of measures carried out in the areas polluted with radionuclides.

    Evaluation of the frequency index for mtDNA particular sequences in the Caucasian population is crucial for forensic practice. There are two hypervariable regions in the mtDNA D-loop, HV1 and HV2. Both of them, 610 bp altogether, were sequenced, 342 bp from the hypervariable region HV1 (16024-16365) and 268 bp from the hypervariable region HV2 (73-340). We have analyzed 374 randomly selected non-related individuals of th e Caucasian population and 192 individuals of the Roma subpopulation living in Slovakia. The main goals of the work were to introduce and standardize methods of analysis of variability of the HV1 and HV2 regions of mtDNA for forensic use; to characterize the variability of mtDNA in the Slovakian population taking into account the subpopulations; classification of mtDNA profiles into haplotype groups, and comparison with other haplotype groups in Europe in the frame of phylogenetic studies.

  8. Correlations of urinary cadmium with hypertension and diabetes in persons living in cadmium-contaminated villages in northwestern Thailand: A population study

    International Nuclear Information System (INIS)

    Risk for hypertension and diabetes has not been conclusively found to be a result of cadmium exposure. A population-based study was conducted in 2009 to examine the correlations of urinary cadmium, a good biomarker of long-term cadmium exposure, with hypertension and diabetes in persons aged 35 years and older who lived in the 12 cadmium-contaminated rural villages in northwestern Thailand. A total of 5273 persons were interviewed and screened for urinary cadmium, hypertension, and diabetes. The geometric mean level of urinary cadmium for women (2.4±2.3 μg/g creatinine) was significantly greater than that for men (2.0±2.2 μg/g creatinine). Hypertension was presented in 29.8% of the study population and diabetes was detected in 6.6%. The prevalence of hypertension significantly increased from 25.0% among persons in the lowest tertile of urinary cadmium to 35.0% in the highest tertile. In women, the rate of hypertension significantly increased with increasing urinary cadmium levels in both ever and never smokers, after adjusting for age, alcohol consumption, body mass index, and diabetes. In men, such association was less significantly found in never smokers. The study revealed no significant association between urinary cadmium and diabetes in either gender. Our study supports the hypothesis that environmental exposure to cadmium may increase the risk of hypertension. Risk for diabetes in relation to cadmium exposure remains uncertain in this exposed population.

  9. Risk factors of arterial hypertension prevalence and incidence in the population living in the radionuclide contaminated territory

    International Nuclear Information System (INIS)

    Higher prevalence of hypertension among population in the radionuclide contaminated zones was positively associated with body mass index (P2 (P<0.001), alcohol abuse (P<0.01), gustatory sensitivity to sodium chloride (P<0.001), heart rate (P<0.001), smoking (P<0.01), sex (P<0.01), profession (P<0.05), total cholesterol (P<0.05). The hypertension incidence from associated risk factors was positively interacted with age (P<0.001), family history of premature cardiovascular disease (P<0.001), body mass index (P<0.001), alcohol abuse (P<0.001), heart rate (P<0.001), Cs 137 deposition density (P<0.05), gustatory sensitivity to sodium chloride (P<0.05), total cholesterol (P<0.05). The residence of people in the radionuclide contaminated zones is an independent risk factor of arterial hypertension

    Beukema, J. J.

    Numerical densities and size distributions in populations of the spatangoid Echinocardium cordatum were followed at 19 fixed sampling stations with sandy sediments at depths of 6 to 18 m off the west-Frisian islands of Texel and Terschelling. Recruitment was irregular with some recruitment occurring during half of the years and successful year classes developing during only 3 of the years in the 10 year period of observation (1972-1982). Annual mortality of the strong year class born in 1972 was rather regular in the ages of 1 to 7 years, averaging ˜27% in the 2 areas, but was followed by catastrophic mortality at most stations during the severe winter 1979. Growth was rapid. A mean length of 2 to 2.5 cm was reached after 2 growing seasons and 4 cm after 4 or 5 growing seasons.

    Full Text Available Abstract Objective To report emerging data on the use of highly active antiretroviral therapy (HAART in Argentina by assessing patterns of HAART access and late vs early treatment initiation in a population-based cohort of adults infected with HIV type-1. Design The Prospective Study on the Use and Monitoring of Antiretroviral Therapy (PUMA is a study of 883 HIV-positive individuals enrolled in the Argentinean drug treatment program. Individuals were 16 years of age and older and were recruited from 10 clinics across Argentina. Methods Sociodemographic and clinical characteristics were examined using contingency tables (Pearson chi-square test and Fisher exact test for categoric variables and Wilcoxon rank-sum test for continuous variables. To analyze time to initiation of HAART we used Kaplan-Meier methods and Cox regression. Results Patients who initiated HAART were more likely to be older, have an AIDS-defining illness, be an injection drug user (IDU, have a lower median CD4 cell count, have a higher median viral load, and be less likely to be men who have sex with men (MSM. In multivariate analysis, AIDS-defining illness and plasma viral load were significantly associated with time to starting therapy. Patients who received late access were more likely to be diagnosed with AIDS and have higher median plasma viral loads than those receiving early access. Conclusion Our results indicate that despite free availability of treatment, monitoring, and care in Argentina, a significant proportion of men and women are accessing HAART late in the course of HIV disease. Further characterization of the HIV-positive population will allow for a more comprehensive evaluation of the impact of HAART within the Argentinean drug treatment program.

  12. Comparison of blood serum selenium concentrations from elderly population living in Sao Paulo city and literature data

    International Nuclear Information System (INIS)

    Selenium is an essential nutrient of fundamental importance to human biology. This element is a component of the enzyme glutathione peroxidase that avoids the formation of free radicals protecting the organism against the oxidative damage. The Se concentrations in serum vary from one part of the world to another and this fact has been satisfactorily explained as a consequence of different Se intakes of the population. The main objective of this paper was the determination of serum Se concentrations in healthy elderly population included in a program for 'Successful Ageing' of the Hospital das Clinicas, Sao Paulo University Medical School. The blood samples were collected after a 12 h fast from 32 subjects aged 60 to 87 years. The blood was centrifuged after completely clotted and 4.0 mL of serum were freeze.dried for Se determination using neutron activation analysis. The serum samples and Se standard were irradiated for 16 h under a thermal neutron flux of de 5 x 1012 n cm-'2 s-1 at the IEA-R1 nuclear reactor. Se was determined by measuring the gamma activity of 75Se using an HGe detector coupled to a gamma ray spectrometer. The mean value of (0.92±0.07) μmol L-1 was obtained for serum Se concentration. This value is within the data used as reference values in clinical laboratories and those published in literature. Results obtained for certified reference materials NIST 1566b Oyster Tissue and NIST 1577b Bovine Liver showed good precision and agreed with the certified values. The relative standard deviation of the results was lower than 4.8 % and relative error lower than 0.97 %. Detection limit value obtained for serum Se determination was 0.003 μmol L-1. (author)

    A cross sectional study using environmental and biological samples was implemented to assess the association between arsenic (As) concentrations in the environment and urinary As levels of residents living in an area where the soil is naturally As rich. As was measured in drinking water, atmospheric particulate matter, and soil and a geographic information system was used to assign environmental concentrations closest to the participants' dwellings and the sum of inorganic As and metabolites in urine samples. The only potential source of As environmental contamination was from soil with a range of 13-131 mg As/kg of dry matter. As(V) was the only species present among As extracted from the analyzed soil samples. The chemical extraction showed a poor mobility of As soil. There was no difference between child and teenager, and adult urinary As concentrations, though men had higher urinary As concentrations than women (p < 0.001). Given the important differences in lifestyle between 7-18 year olds, men, and women, these groups were analyzed separately. Whilst we were unable to find a stable model for the 7-18 year old group, for the adult men group we found that seafood consumption in the 3 days prior to the investigation (p = 0.02), and beer (p = 0.03) and wine consumption in the 4 days before the study, were associated with As urinary levels ({mu}g/L). In adult women, creatinine was the only variable significantly associated with As urinary concentration ({mu}g/L). The concentrations we measured in soils were variable and although high, only moderately so and no link between As concentrations in the soil and urinary As concentrations could be found for either men or women. Some individual factors explained half of the variability of adult men urinary As levels. The unexplained part of the variability should be searched notably in As mobility in soil and uncharacterized human behavior.

    Alcohol use typically is initiated during adolescence, an age period that overlaps with critical structural and functional maturation of the brain. Brain maturation and associated improvements in decision-making continue into the second decade of life, reaching plateaus within the period referred to as “emerging adulthood” (18–24 years). Emerging adulthood is the typical age span of the traditionally aged college student, which includes the age (21 years) when alcohol consumption becomes lega...

    Full Text Available Abstract Objective To estimate 12-month prevalence and co-occurrence of symptoms of specific mental problems among US adolescents (12–17 years by age, sex and racial/ethnic subgroups. Method Data from the 2000 National Household Survey of Drug Abuse (NHSDA adolescent sample are used to estimate prevalence and co-occurrence rates using the DISC predictive scales. Multiple logistic regressions were used to derive significant correlates of each domain of DPS-derived symptom cluster indicators of psychiatric problems and of severe comorbidity, with control of demographics and environmental factors. Setting The National Household Survey on Drug Abuse (NHSDA, a national household probability sample, includes a nationally representative sample of 12–17 year-old adolescents (N = 19,430, through in-home surveys. Results Three out of five adolescents screened positive for at least one DPS symptom cluster with estimates for specific symptom cluster ranging over 9.7% (substance use disorder, 13.4% (affective, 36.3% (disruptive-behavior, and 40.1% (anxiety. Co-occurrence was high with almost one-third of any DPS symptom cluster reporting multiple positive screens of four or more clusters. Blacks and younger females were most likely to report mental health problems and co-occurrence. Conclusion Mental health problems among U.S. youth may be far more common than previously believed, although these symptoms have not yet reached the point of clinical impairment. The data speak to important patterns of age, gender and racial/ethnic differences in mental health problems deserving of further study.

  20. Metal-induced stress in bivalves living along a gradient of Cd contamination: relating sub-cellular metal distribution to population-level responses

    International Nuclear Information System (INIS)

    The use of biomarkers to assess the impacts of contaminants on aquatic ecosystems has noticeably increased over the past few years. Few of these studies, however, have contributed to the prediction of ecologically significant effects (i.e., at the population or community levels). The present field study was designed to evaluate the potential of metallothionein (MT) and sub-cellular metal partitioning measurements for predicting toxic effects at higher levels of the biological organization in freshwater bivalves (Pyganodon grandis) chronically exposed to Cd. For that purpose, we quantitatively sampled P. grandis populations in the littoral zone of nine lakes on the Precambrian Canadian Shield during two consecutive summers (1998 and 1999); lakes were characterized by contrasting Cd levels but similar trophic status. We tested relationships between the population status of P. grandis (i.e., growth parameters, density, biomass, secondary production, turnover ratio and cumulative fecundity) and (i) ambient Cd concentrations, (ii) sub-organismal responses (MT concentrations in the gill cytosol of individuals and Cd concentrations in three metal-ligand pools identified as M-HMW, the high molecular weight pool, M-MT, the metallothionein-like pool and M-LMW, the low molecular weight pool) and (iii) ecological confounding factors (food resources, presence of host fishes for the obligatory parasitic larval stage of P. grandis). Our results show that littoral density, live weight, dry viscera biomass, production and cumulative fecundity decreased with increasing concentrations of the free-cadmium ion in the environment (Pearson's r ranging from -0.63 to -0.78). On the other hand, theoretical maximum shell lengths (L∞) in our populations were related to both the dissolved Ca concentration and food quality (sestonic C and N concentrations). Overall, Cd concentrations in the gill cytosolic HMW pool of the individual molluscs were the biomarker response that was most frequently

    Radiation-hygiene studies of 848 flats and houses of Akchatau village of Dzhezkazgan region were carried out. The ferro-concrete from local industrial wastes was widely used in early stage of the village development during construction of dwelling houses. There were wastes of tungsten and molybdenum industry and its are powerful source of radon. Among houses with radon concentration exceeding maximum permissible concentration (MPC) in 5 and higher times there are houses built from local materials: saman (65.9 %), stone (60.5 %) and ferro- concrete (52.0 %). The largest radon concentration with exceeding of MPC in to 20 times were registered indoor constructed from ferro-concrete with mean value of natural gamma-background - 63.7 μR/h under established norm 22 μR/h. During period from 1986 up to 1990 the morbidity of inhabitants make up 19927.9 on 10 thousand of population (that higher than analogous index by region in to 1.8 times). It was defined, that among different kinds illness the greatest specific gravity take respiratory system diseases - 62.2 %, nervous system - 9,3 % and blood circulation system - 7,1 %

  2. Rise in psychotropic drug prescribing in children and adolescents during 1992-2001: a population-based study in the UK

    International Nuclear Information System (INIS)

    Background The trend towards increased psychotropic drug prescribing in children and adolescents is well recognised in North America and continental Europe. However, it is unclear to what extent these studies are applicable to clinical practice in the United Kingdom (UK). This study was conducted to estimate the prevalence of psychotropic drug prescribing in children and adolescents aged <19 years in general practice in the UK from January 1992 to December 2001. Methods Data were obtained from the General Practice Research Database (GPRD). Annual age- and sex-specific prevalence of psychotropic drug prescribing was calculated. Results A total of 143,079 prescriptions were issued to 34,398 study subjects. Stimulant prescriptions rose significantly from 0.03 per 1,000 (95% confidence interval 0.02-0.04) in 1992 to 2.9 per 1,000 (2.52-3.32) in 2001; a 96-fold increase. Methylphenidate accounted for the majority of stimulant prescriptions; 2.4% (349/14,370) of stimulant prescriptions were prescribed to children aged <6 years. Increased prescribing was also noted for antidepressants (1.6-fold), hypnotics/anxiolytics (1.3-fold), antipsychotics (1.3-fold) and anticonvulsants (1.3-fold), whilst the prevalence of clonidine and lithium prescribing remained fairly stable throughout the study period. The use of antidepressant, hypnotic/anxiolytic and anticonvulsant increased with increasing age. A high proportion of boys received stimulants, whereas antidepressants and hypnotics/anxiolytics were more likely prescribed to girls. Conclusion There is an increased trend of psychotropic drug use in children and adolescents in the UK practice. Since most psychotropic drugs are not licensed for use in children at this time, research is needed to investigate the efficacy and long-term safety in this population

    Full Text Available Introduction: The present study was ‎designed to evaluate the prevalence of child abuse in a child and adolescent psychiatric clinical population. Methods: This cross-sectional study was conducted in a clinical population of children and adolescents aged 8-18 years. 80 out-patients and 94 in-patients were selected according to probability proportional to size sampling. Kiddie schedule for affective disorder and schizophrenia questionnaire, a demographic questionnaire, and child abuse self-report scale were filled for each subject. Data were analyzed by using Stata software. Results: Among the out-patient subjects, 50 were male (62.5% and 30 were female (37.5%; for in-patient these subjects numbers were 76 (80.9% and 18 (19.1%, respectively. The mean age of subjects was 15.2 years in the in-patient group and 11.7 years in the out-patient group. In 66.1% of abuse cases the perpetrators were parents, 5.2% siblings, and 28.7% someone else. Among in-patient subjects, summed up prevalence rates of severe and very severe psychological abuse, neglect, physical abuse, and sexual abuse were 11.7, 33.0, 2.1, and 0.0%, respectively; for out-patient subjects these values were 3.8, 11.2, 3.8, and 0.0%, respectively. Moreover, among in-patient subjects, prevalence rates of moderate psychological abuse, neglect, physical abuse, and sexual abuse were 27.7, 27.7, 24.5, and 4.3%, respectively; and for out-patient subjects these values were 30.0, 27.5, 11.2, and 0.0%, respectively. Subjects with attention-deficit/hyperactivity disorder (ADHD suffered a higher rate of physical abuse, whereas, subjects with bipolar mood disorder (BMD suffered a higher rate of sexual abuse. Conclusion: The prevalence of child abuse is highly prevalent in children and adolescents with psychiatric disorders. It is recommended that this population be screened routinely for child abuse.

    Full Text Available Plasmodiums are protozoa that may infect various hosts. Only five species are now recognized as naturally parasitizing humans: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale and Plasmodium knowlesi. This fifth species, P. knowlesi, previously identified as naturally parasitizing the monkey Macaca fascicularis, has been microscopically confused for a long time with P. malariae or P. falciparum and it was not possible to correctly differentiate them until the advent of molecular biology. To date, natural human infections with P. knowlesi only occur in Southeast Asia and a similar phenomenon of natural transmission of simian plasmodium to humans has not been reported elsewhere. This study was conducted to investigate a possible transmission of African small monkey's plasmodium to humans in populations living near the rainforest of the Democratic Republic of Congo (DRC where several species of non-human primates are living. Two successive real-time PCRs were identified in the literature and used in combination for purpose. Only P. falciparum was found in this study. However, studies with larger samples and with more advanced techniques should be conducted.

    Full Text Available OBJECTIVE: This study aimed to assess diet quality among adolescents with HIV/AIDS. METHOD: A cross-sectional study was conducted involving patients with HIV/AIDS treated in a referral hospital in Sao Paulo, Brazil. Eighty-eight adolescents (10-19 years of age participated in the study. Information on disease history and use of medication were obtained from medical records. The participants responded to two 24-hour diet recalls. Diet quality was assessed by means of the Healthy Eating Index-2005 (HEI-2005 adapted to the Brazilian population. Pearson's correlation coefficients were calculated. Mean HEI-2005 scores were compared according to the independent variables using either the Student's t-test or the Mann-Whitney test. RESULTS: The mean HEI-2005 score was 51.90 (SE = 0.90. The components with the lowest means were whole grains and sodium. Components with highest means were total grains and oils. No correlations were found between the independent variables and HEI score. Adolescents living in foster homes had higher means for total fruit and lower means for meat and beans in comparison to adolescents living with their families. Girls had higher means for milk and lower means for calories from solid fats, alcoholic beverages, and added sugars in comparison to boys. CONCLUSIONS: Adolescents with HIV/AIDS exhibited a similar eating pattern to that of adolescents in the general population: high consumption of added sugar, saturated fat, and sodium, and insufficient ingestion of whole grains and fruits. Special attention should be paid to the diet of adolescents with HIV/AIDS, who are at greater risk of developing cardiovascular and other chronic diseases.

  7. CYP2A6 and CYP2E1 polymorphisms in a Brazilian population living in Rio de Janeiro

    2006-02-01

    Full Text Available Cytochrome P450 (CYP is a superfamily of enzymes involved in the metabolism of endogenous compounds and xenobiotics. CYP2A6 catalyzes the oxidation of nicotine and the activation of carcinogens such as aflatoxin B1 and nitrosamines. CYP2E1 metabolizes ethanol and other low-molecular weight compounds and can also activate nitrosamines. The CYP2A6 and CYP2E1 genes are polymorphic, altering their catalytic activities and susceptibility to cancer and other diseases. A number of polymorphisms described are ethnic-dependent. In the present study, we determined the genotype and allele frequencies of the main CYP2A6 and CYP2E1 polymorphisms in a group of 289 volunteers recruited at the Central Laboratory of Hospital Universitário Pedro Ernesto. They had been residing in the city of Rio de Janeiro for at least 6 months and were divided into two groups according to skin color (white and non-white. The alleles were determined by allele specific PCR (CYP2A6 or by PCR-RFLP (CYP2E1. The frequencies of the CYP2A6*1B and CYP2A6*2 alleles were 0.29 and 0.02 for white individuals and 0.24 and 0.01 for non-white individuals, respectively. The CYP2A6*5 allele was not found in the population studied. Regarding the CYP2E1*5B allele, we found a frequency of 0.07 in white individuals, which was statistically different (P < 0.05 from that present in non-white individuals (0.03. CYP2E1*6 allele frequency was the same (0.08 in both groups. The frequencies of CYP2A6*1B, CYP2A6*2 and CYP2E1*6 alleles in Brazilians are similar to those found in Caucasians and African-Americans, but the frequency of the CYP2E1*5B allele is higher in Brazilians.

    Full Text Available Cytochrome P450 (CYP is a superfamily of enzymes involved in the metabolism of endogenous compounds and xenobiotics. CYP2A6 catalyzes the oxidation of nicotine and the activation of carcinogens such as aflatoxin B1 and nitrosamines. CYP2E1 metabolizes ethanol and other low-molecular weight compounds and can also activate nitrosamines. The CYP2A6 and CYP2E1 genes are polymorphic, altering their catalytic activities and susceptibility to cancer and other diseases. A number of polymorphisms described are ethnic-dependent. In the present study, we determined the genotype and allele frequencies of the main CYP2A6 and CYP2E1 polymorphisms in a group of 289 volunteers recruited at the Central Laboratory of Hospital Universitário Pedro Ernesto. They had been residing in the city of Rio de Janeiro for at least 6 months and were divided into two groups according to skin color (white and non-white. The alleles were determined by allele specific PCR (CYP2A6 or by PCR-RFLP (CYP2E1. The frequencies of the CYP2A6*1B and CYP2A6*2 alleles were 0.29 and 0.02 for white individuals and 0.24 and 0.01 for non-white individuals, respectively. The CYP2A6*5 allele was not found in the population studied. Regarding the CYP2E1*5B allele, we found a frequency of 0.07 in white individuals, which was statistically different (P < 0.05 from that present in non-white individuals (0.03.

    Full Text Available BACKGROUND: Lyme borreliosis (LB caused by spirochetes of the Borrelia burgdorferi sensu lato complex is the most common tick-borne disease in the northern hemisphere. Data on the distribution and on risk factors in Germany are sketchy. METHODOLOGY/PRINCIPAL FINDINGS: Blood samples of a nationwide population-based cross-sectional study from 2003-2006 in children and adolescents aged 1 to 17 years in Germany (KiGGS were analysed (n = 12,614 to assess the seroprevalence of anti-Borrelia antibodies. Data from standardized interviews were used to assess potential risk factors. First, sera were screened for anti-Borrelia antibodies by ELISA. The overall prevalence was 4.8% (95% confidence interval (CI 4.3-5.4%. Positive and borderline ELISA test results were confirmed by a line blot revealing a combined prevalence of 4.0% (95% CI 3.6-4.5%. Seroprevalence of ELISA was significantly higher in males (odds ratio (OR = 1.37; CI 1.15-1.63 and in the southern part of Germany (OR = 1.41; CI 1.09-1.83, but significantly lower in children and adolescents with migration background (OR = 0.33; CI 0.24-0.44. Study participants from households with cats had a higher chance of seropositivity (OR = 6.7; CI 5.6-8.0. In a multivariable model the odds of seropositivity increases by 11% for every year of age for boys and 6% for girls. CONCLUSIONS/SIGNIFICANCE: This survey is the first nationwide, representative seroprevalence survey of LB in children and young adolescents. The study shows that infections with Borrelia burgdorferi are endemic in all parts of Germany despite regional differences. Even at a young age children are exposed to tick bites including seropositivity. Encouraging a thorough check for ticks and promptly removal of ticks are the key public health strategies to reduce the risk of LB and other tick-borne diseases in children and adolescents. Further epidemiological studies are warranted to better understand the burden of disease related to LB.

    Full Text Available Abstract Background MDFT (Multidimensional Family Therapy is a family based outpatient treatment programme for adolescent problem behaviour. MDFT has been found effective in the USA in adolescent samples differing in severity and treatment delivery settings. On request of five governments (Belgium, France, Germany, the Netherlands, and Switzerland, MDFT has now been tested in the joint INCANT trial (International Cannabis Need of Treatment for applicability in Western Europe. In each of the five countries, study participants were recruited from the local population of youth seeking or guided to treatment for, among other things, cannabis use disorder. There is little information in the literature if these populations are comparable between sites/countries or not. Therefore, we examined if the study samples enrolled in the five countries differed in baseline characteristics regarding demographics, clinical profile, and treatment delivery setting. Methods INCANT was a multicentre phase III(b randomized controlled trial with an open-label, parallel group design. It compared MDFT with treatment as usual (TAU at and across sites in Berlin, Brussels, Geneva, The Hague and Paris. Participants of INCANT were adolescents of either sex, from 13 through 18 years of age, with a cannabis use disorder (dependence or abuse, and at least one parent willing to take part in the treatment. In total, 450 cases/families were randomized (concealed into INCANT. Results We collected data about adolescent and family demographics (age, gender, family composition, school, work, friends, and leisure time. In addition, we gathered data about problem behaviour (substance use, alcohol and cannabis use disorders, delinquency, psychiatric co-morbidity. There were no major differences on any of these measures between the treatment conditions (MDFT and TAU for any of the sites. However, there were cross-site differences on many variables. Most of these could be explained by

    Full Text Available OBJECTIVE: To assess the prevalence and the factors associated with common mental disorders among adolescents in Pelotas, a southern Brazilian city. METHOD: A population based cross-sectional study was carried out in the urban area of Pelotas. Multi-stage sampling was used to obtain a sample of adolescents aged between 15 and 18 years. Adolescents were interviewed using a self-report confidential questionnaire. The presence of common mental disorders was assessed using the Self-Reporting Questionnaire 20 (SRQ-20. Multivariate analysis was carried out using the Poisson regression with a robust adjustment of variance and control for design effect. RESULTS: Nine hundred and sixty adolescents were interviewed. The prevalence of common mental disorders was 28.8%. Adolescents aged 17 years showed prevalence of 1.37 (95% CI 1.06-1.78 times greater than the 15 year olds. Adolescents whose mothers had between 5 and 8 years of schooling had a prevalence 1.42 (95% CI 1.01-1.51 times greater than those whose mothers had more than 8 years of schooling. Smoking and sedentary behavior were also associated with an increased prevalence of common mental disorders. Those who were dissatisfied with their body image showed a prevalence of 1.47 (95% CI 1.07-2.02. CONCLUSIONS: Maternal schooling, tobacco smoking, sedentary behavior and body image dissatisfaction were factors associated with the presence of common mental disorders.OBJETIVO: Avaliar a prevalência e os fatores associados à presença de transtornos mentais comuns entre adolescentes em Pelotas, uma cidade do sul do Brasil.

    Background: In Sicily, people live near areas characterized by the presence of environmental polluting substances derived from urbanization and industrialization. In the areas of Augusta-Priolo (SR,Gela (CL and Milazzo (ME, the increase of number of pathologies could be linked with environmental pollution. The aim of this paper is to present an overview of the available data and studies to underline the importance of these sources to conduct epidemiological survey in Sicily, besides to the analysis of mortality and morbidity.

    Methods: An evaluation of the health status of the residential population was done comparing the mortality and morbidity of the local population with the mortality and morbidity of a reference population. Data was obtained from the Italian national office of statistics and Hospital Discharge Records. Standardized Mortality Ratios and Standardized Hospitalization Ratios were calculated.

    Results: In the area of Augusta-Priolo we observed, in for men, a significative increase in mortality and hospital admissions for colon-rectal, trachea, bronchus, lung and pleura cancers. In Biancavilla, we observed an increase in mortality for pleura cancer in men and women and an increase in morbidity in women only. In Gela, a significant increase in mortality in males and females was observed only for tumoral diseases. In Milazzo, we only found a significant increase in the incidence of larynx cancer and cardiovascular disease for men and in women of pulmonary disease for women.

    Conclusions: This first review allowed us to update previous analyses of mortality data conducted in the same areas. The results, even taking into account the differences between the areas,, highlights changes in health status related to some diagnostic groups. These could be linked with pollution. Now that the available health data has been revised and updated new studies must

    Full Text Available O objetivo desse estudo foi compreender longitudinalmente o processo de reinserção familiar de três adolescentes que moravam em abrigos. Visitas domiciliares e Entrevistas de Reinserção foram utilizadas com os participantes e um membro da família, durante um período que variou de seis a 18 meses. Os resultados indicaram que as famílias se encontravam em situação de vulnerabilidade; não houve uma preparação dos jovens e familiares para o retorno; e não foi disponibilizado apoio após o desligamento da instituição. Dois dos adolescentes demonstraram satisfação com a reinserção após alguns meses de desligamento, embora a situação de pobreza e baixo desempenho escolar fossem percebidos como problemas pelos participantes. No terceiro caso, problemas na condução da reinserção fizeram com que a adolescente fosse reabrigada. Discute-se a necessidade de políticas públicas e de programas desenvolvidos por profissionais capacitados, em parceria com os abrigos, que visem à promoção da convivência familiar.The goal of this study was to longitudinally understand the family reunification process of three adolescents who lived in shelters. Home visits and Reunification Interview were used with the adolescents and a family member, during a time that ranged from six to 18 months. The results highlighted that such families socially vulnerable; there was no family and adolescents preparation for the reinsertion; and there was no support after such process of detachment from the institution. Two adolescents were satisfied with reunification after some months, although the poor conditions and low academic achievement had been perceived as a problem by the participants. On the third case, there were problems to handle reunification and the adolescent returned to the shelter. The need of public policies and programs, develop by able professionals, engaging with the shelters, are discussed, aiming to promotion family reunification.

    A series of 82 children and adolescents with moderate and severe persistent asthma was studied. Their psychopathological problems were compared to those of 82 healthy subjects, matched for age, sex and socio-economic status. The patients completed the Child Depression Inventory, an inventory of fears and anxiety (ECAP) and the Coopersmith Self Esteem Inventory. Parents of asthmatic children filled in the Child Behavior Check List to assess their social competence. The patients were examined with the revised Kiddie Schedule for Affective Disorders and Schizophrenia. There were more anxiety symptoms in the asthmatic group than in the control group. Asthmatics were not significantly more depressed than controls and their self-esteem was as good. We found 29 anxiety disorders, four affective disorders and four disruptive behavior disorders. Generalized anxiety disorder was the main diagnosis (n=24). The asthmatic subgroup presenting anxiety and affective disorders had poorer self esteem, fewer activities and worse social competence than other asthmatics and controls. Adolescents did not seem to have more emotional disturbances than younger patients. Girls did not have more DSM IV anxiety or affective disorders than boys. PMID:10802131
