    This article reports a study of the function and composition of social support networks among diverse lesbian, gay, and bisexual (LGB) men and women (n = 396) in comparison to their heterosexual peers (n = 128). Data were collected using a structured social support network matrix in a community sample recruited in New York City. Our findings show that gay and bisexual men may rely on "chosen families" more than lesbian and bisexual women. Both heterosexuals and LGBs relied less on family and more on other people (e.g., friends, coworkers) for everyday social support (e.g., recreational and social activities, talking about problems). Providers of everyday social support were most often of the same sexual orientation and race/ethnicity as participants. In seeking major support (e.g., borrowing large sums of money), heterosexual men and women along with lesbian and bisexual women relied primarily on their families, but gay and bisexual men relied primarily on other LGB individuals. Racial/ethnic minority LGBs relied on LGB similar others at the same rate as did White LGBs but, notably, racial/ethnic minority LGBs reported receiving fewer dimensions of support.

    Despite progressive legislative developments and increased visibility of sexual and gender minority populations in the general population, mass media often report that this population face a wide range of discrimination and inequalities. LGBT (lesbian, gay, and bisexual, and transgender) populations have not been considered as priority research populations in Nepal. Research in other geographical settings has shown an increased risk of poor mental health, violence, and suicide and higher rates of smoking, as well as alcohol and drugs use among LGBT populations. They are also risk for lifestyle-related illness such as cancer, diabetes, and heart diseases. Currently, in Nepal, there is a lack of understanding of health and well-being, social exclusion, stigma, and discrimination as experienced by these populations. Good-quality public health research can help design and implement targeted interventions to the sexual and gender minority populations of Nepal. PMID:26543163

    Stigma operates at multiple levels, including intrapersonal appraisals (e.g., self-stigma), interpersonal events (e.g., hate crimes), and structural conditions (e.g., community norms, institutional policies). Although prior research has indicated that intrapersonal and interpersonal forms of stigma negatively affect the health of the stigmatized, few studies have addressed the health consequences of exposure to structural forms of stigma. To address this gap, we investigated whether structural stigma-operationalized as living in communities with high levels of anti-gay prejudice-increases risk of premature mortality for sexual minorities. We constructed a measure capturing the average level of anti-gay prejudice at the community level, using data from the General Social Survey, which was then prospectively linked to all-cause mortality data via the National Death Index. Sexual minorities living in communities with high levels of anti-gay prejudice experienced a higher hazard of mortality than those living in low-prejudice communities (Hazard Ratio [HR] = 3.03, 95% Confidence Interval [CI] = 1.50, 6.13), controlling for individual and community-level covariates. This result translates into a shorter life expectancy of approximately 12 years (95% C.I.: 4-20 years) for sexual minorities living in high-prejudice communities. Analysis of specific causes of death revealed that suicide, homicide/violence, and cardiovascular diseases were substantially elevated among sexual minorities in high-prejudice communities. Strikingly, there was an 18-year difference in average age of completed suicide between sexual minorities in the high-prejudice (age 37.5) and low-prejudice (age 55.7) communities. These results highlight the importance of examining structural forms of stigma and prejudice as social determinants of health and longevity among minority populations. PMID:23830012

    SUMMARY Understanding the mental health needs of lesbian and bisexual (sexual minority) women is an integral part of designing and providing appropriate mental health services and treatment for them. In an effort to understand the mental health needs of sexual minority women who seek community treatment, a chart review was conducted of the 223 lesbian and bisexual women who presented for services between July 1, 1997 and December 31, 2000 at Fenway Community Health in Boston, MA. Data are based on clients' self-reports and clinician assessments of clients' presenting problem, relevant developmental history, prior mental health and substance abuse treatment, current reports of emotional/psychological symptoms, and areas of impaired functioning. Although substance abuse and suicidal ideation were commonly reported problems, other concerns were more frequently reported. High percentages of lesbians and bisexual women reported relationship concerns and lack of adequate social networks; rates of depression and anxiety based on clinicians' assessments were also high. Overall, lesbians and bisexual women did not differ in the issues they brought to treatment or level or types of impairment. Compared with previous community survey samples, however, study participants appeared to be healthier than general, non-clinical samples of self-identified lesbians, possibly reflecting the special characteristics of sexual minority women who seek treatment in specialized community sites such as the Fenway. Although patients who come to these sites may not represent the more general population of sexual minority women, community health centers known to serve lesbian, gay, bisexual and transgender (LGBT) individuals may be fruitful access points for studying the mental health status and treatment needs of sexual minority women.

    Objective Risk factors for breast, colorectal, and lung cancer are known to be more common among lesbian, gay, and bisexual (LGB) individuals, suggesting they may be more likely to develop these cancers. Our objective was to determine differences in cancer incidence by sexual orientation, using sexual orientation data aggregated at the county level. Methods Data on cancer incidence were obtained from the California Cancer Registry and data on sexual orientation were obtained from the California Health Interview Survey, from which a measure of age-specific LGB population density by county was calculated. Using multivariable Poisson regression models, the association between the agerace-stratified incident rate of breast, lung and colorectal cancer in each county and LGB population density was examined, with race, age group and poverty as covariates. Results Among men, bisexual population density was associated with lower incidence of lung cancer and with higher incidence of colorectal cancer. Among women, lesbian population density was associated with lower incidence of lung and colorectal cancer and with higher incidence of breast cancer; bisexual population density was associated with higher incidence of lung and colorectal cancer and with lower incidence of breast cancer. Conclusions These study findings clearly document links between county-level LGB population density and cancer incidence, illuminating an important public health disparity. PMID:24670430

    2014-01-01

    Introduction Research indicates disparities in risky health behaviors between heterosexual and sexual minority (referred to as LGBQ; also known as lesbian, gay, bisexual, queer, and questioning) youth. Limited data are available for tobacco-use–related behaviors beyond smoking status. We compared data on tobacco age of initiation, product use, and secondhand smoke exposure between general population and LGBQ youth. Methods Data for general population youth were from the statewide, representative 2011 Missouri Youth Tobacco Survey, and data for LGBQ youth were from the 2012 Out, Proud and Healthy survey (collected at Missouri Pride Festivals). Age-adjusted Cochran-Mantel-Haenszel tests were used to examine differences between general population (N = 1,547) and LGBQ (N = 410) youth, aged 14 to 18 years. Logistic regression models identified variables associated with current smoking. Results The 2 groups differed significantly on many tobacco-use–related factors. General population youth initiated smoking at a younger age, and LGBQ youth did not catch up in smoking initiation until age 15 or 16. LGBQ youth (41.0%) soon surpassed general population youth (11.2%) in initiation and proportion of current smokers. LGBQ youth were more likely to use cigars/cigarillos, be poly-tobacco users, and be exposed to secondhand smoke (SHS) in a vehicle (for never smokers). Older age (odds ratio [OR] = 1.39, 95% confidence interval [95% CI] = 1.18–1.62), female sex (OR = 1.64, 95% CI = 1.13–2.37), LGBQ identity (OR = 3.86, 95% CI = 2.50–5.94), other tobacco product use (OR = 8.67, 95% CI = 6.01–12.51), and SHS exposure in a vehicle (OR = 5.97, 95% CI = 3.83–9.31) all significantly increased the odds of being a current smoker. Conclusion This study highlights a need for the collection of data on sexual orientation on youth tobacco surveys to address health disparities among LGBQ youth. PMID:24995655

    Objectives. We examined whether past-year suicidality among sexual-minority adolescents was more common in neighborhoods with a higher prevalence of hate crimes targeting lesbian, gay, bisexual, and transgender (LGBT) individuals. Methods. Participants’ data came from a racially/ethnically diverse population-based sample of 9th- through 12th-grade public school students in Boston, Massachusetts (n = 1292). Of these, 108 (8.36%) reported a minority sexual orientation. We obtained data on LGBT hate crimes involving assaults or assaults with battery between 2005 and 2008 from the Boston Police Department and linked the data to the adolescent’s residential address. Results. Sexual-minority youths residing in neighborhoods with higher rates of LGBT assault hate crimes were significantly more likely to report suicidal ideation (P = .013) and suicide attempts (P = .006), than were those residing in neighborhoods with lower LGBT assault hate crime rates. We observed no relationships between overall neighborhood-level violent and property crimes and suicidality among sexual-minority adolescents (P > .05), providing evidence for specificity of the results to LGBT assault hate crimes. Conclusions. Neighborhood context (i.e., LGBT hate crimes) may contribute to sexual-orientation disparities in adolescent suicidality, highlighting potential targets for community-level suicide-prevention programs.

    2012-01-01

    Objectives. We examined whether the health risk behaviors of lesbian, gay, and bisexual (LGB) youths are determined in part by the religious composition of the communities in which they live. Methods. Data were collected from 31 852 high school students, including 1413 LGB students, who participated in the Oregon Healthy Teens survey in 2006 through 2008. Supportive religious climate was operationalized according to the proportion of individuals (of the total number of religious adherents) who adhere to a religion supporting homosexuality. Comprehensive data on religious climate were derived from 85 denominational groups in 34 Oregon counties. Results. Among LGB youths, living in a county with a religious climate that was supportive of homosexuality was associated with significantly fewer alcohol abuse symptoms (odds ratio [OR] = 0.58; 95% confidence interval [CI] = 0.40, 0.85) and fewer sexual partners (OR = 0.77; 95% CI = 0.60, 0.99). The effect of religious climate on health behaviors was stronger among LGB than heterosexual youths. Results remained robust after adjustment for multiple confounding factors. Conclusions. The religious climate surrounding LGB youths may serve as a determinant of their health risk behaviors. PMID:22397347

    Background Emerging research suggests that young adult sexual minorities (identifying as lesbian, gay, or bisexual or engaging in same-sex attractions or behaviors) experience poorer health than their majority counterparts, but many measures of health inequity remain unexamined in population-based research. Purpose To describe a wide range of health status and healthcare access characteristics of sexual minorities in comparison with those of the majority population in a national sample of U.S. young adults. Methods Binary and multinomial logistic regression analyses of Wave IV data (2008) from the National Longitudinal Study of Adolescent Health (participants aged 24–32 years, n=13,088) were conducted. Health measures were self-rated health; diagnosis of any of several physical or mental illnesses or sexually transmitted infections; measured body mass index; depression classified from self-reported symptoms; use of antidepressant and anxiolytic medication; uninsured; forgone care; and receipt of physical, dental, and psychological services. Analyses were conducted in 2012–2013. Results Sexual minority women had elevated odds of most adverse health conditions and lower odds of receiving a physical or dental examination. Sexual minority men had elevated odds of fewer adverse health conditions. Conclusions Young adult sexual minorities are at higher risk of poor physical and mental health. The results highlight the multidimensionality of sexual minority status and respond to calls for greater understanding of the health of this population. PMID:25241194

    Narratives from 33 sexual minority women were examined to discover what factors contributed to their ability to acquire academic success, and what, if any, attributions are evident in some sexual minority women's experiences that provide the ability to persist and graduate. Coping strategies the participants used to gain the resiliency and persistence necessary to acquire academic success are discussed. Intrinsic themes were work ethic values, altruism, and self-efficacy. Extrinsic themes were mentors, family, and friends. Sexual minority women identified the complexity of intrinsic and extrinsic attributions that were used to successfully complete a four-year undergraduate degree in the United States. PMID:24328892

    Very little is known about outcomes of sexual behavior for sexual minority youth. In this chapter, I review relevant literature and draw on findings from my own research to initiate an inquiry into this important topic. I begin with a brief overview of the range of sexual behaviors of sexual minority adolescents and young adults. Next, I describe what we know about positive and negative outcomes of sexual behavior among sexual minority youth. This discussion takes into account physical outcomes, psychological and emotional outcomes, and outcomes related to identity development. Lastly, I discuss the limitations of prior research and propose several goals for future research to expand our understanding of this topic. PMID:24962360

    Background Improving the health of lesbian, gay, and bisexual (LGB) individuals is a Healthy People 2020 goal; however, the IOM highlighted the paucity of information currently available about LGB populations. Purpose To compare health indicators by gender and sexual orientation statuses. Methods Data are from Behavioral Risk Factor Surveillance System surveys conducted January–December of 2010 with population-based samples of non-institutionalized U.S. adults aged over 18 years (N=93,414) in ten states that asked about respondents’ sexual orientation (response rates=41.1%–65.6%). Analyses were stratified by gender and sexual orientation to compare indicators of mental health, physical health, risk behaviors, preventive health behaviors, screening tests, health care utilization, and medical diagnoses. Analyses were conducted in March 2013. Results Overall, 2.4% (95% CI=2.2, 2.7) of the sample identified as LGB. All sexual minority groups were more likely to be current smokers than their heterosexual peers. Compared with heterosexual women, lesbian women had over 30% decreased odds of having an annual routine physical exam, and bisexual women had over 2.5 times the odds of not seeking medical care owing to cost. Compared with heterosexual men, gay men were less likely to be overweight or obese, and bisexual men were twice as likely to report a lifetime asthma diagnosis. Conclusions This study represents one of the largest samples of LGB adults and finds important health inequalities, including that bisexual women bear particularly high burdens of health disparities. Further work is needed to identify causes of and intervention for these disparities. PMID:24650836

    Young adults have high rates of sexually transmitted infections (STIs). Sexual minority youths’ risk for STIs, including HIV, is as high as or higher than sexual majority peers’. Sexual safety, while often treated as a single behavior such as condom use, can be best conceptualized as the result of multiple factors. We used latent class analysis to identify profiles based on ever-used sexual safety strategies and lifetime number of partners among 425 self-identified LGBTQ youth aged 14-19. Data collection took place anonymously online. We identified four specific subgroup profiles for males and three for females, with each subgroup representing a different level and type of sexual safety. Profiles differed from each other in terms of age and outness for males, and in outness, personal homonegativity, and amount of education received about sexual/romantic relationships for females. Youths’ sexual safety profiles have practice implications for sexuality educators, health care professionals, and parents. PMID:24011111

    Objectives. We examined the associations between depressive symptoms and sexual identity and behavior among women with or at risk for HIV. Methods. We analyzed longitudinal data from 1811 participants in the Women’s Interagency HIV Study (WIHS) from 1994 to 2013 in Brooklyn and the Bronx, New York; Chicago, Illinois; Washington, DC; and Los Angeles and San Francisco, California, by comparing depressive symptoms by baseline sexual identity and ongoing sexual behavior. We controlled for age, socioeconomic status, violence history, and substance use. Results. In separate analyses, bisexual women and women who reported having sex with both men and women during follow-up had higher unadjusted odds of depressive symptoms compared with heterosexuals and women who reported only having male sexual partners (adjusted odd ratio [AOR] = 1.36; 95% confidence interval [CI]  = 1.10, 1.69 and AOR = 1.21; 95% CI = 1.06, 1.37, respectively). Age was a significant effect modifier in multivariable analysis; sexual minority women had increased odds of depressive symptoms in early adulthood, but they did not have these odds at midlife. Odds of depressive symptoms were lower among some sexual minority women at older ages. Conclusions. Patterns of depressive symptoms over the life course of sexual minority women with or at risk for HIV might differ from heterosexual women and from patterns observed in the general aging population.

    Sexual minorities face greater exposure to discrimination and rejection than heterosexuals. Given these threats, sexual minorities may engage in sexual orientation concealment in order to avoid danger. This social stigma and minority stress places sexual minorities at risk for anxiety and related disorders. Given that three fourths of anxiety disorder onset occurs before the age of 24, the current study investigated the symptoms of generalized anxiety disorder, social phobia, panic disorder, posttraumatic stress disorder, and depression in sexual minority young adults relative to their heterosexual peers. Secondarily, the study investigated sexual orientation concealment as a predictor of anxiety and related disorders. A sample of 157 sexual minority and 157 heterosexual young adults matched on age and gender completed self-report measures of the aforementioned disorders, and indicated their level of sexual orientation concealment. Results revealed that sexual minority young adults reported greater symptoms relative to heterosexuals across all outcome measures. There were no interactions between sexual minority status and gender, however, women had higher symptoms across all disorders. Sexual minority young women appeared to be at the most risk for clinical levels of anxiety and related disorders. In addition, concealment of sexual orientation significantly predicted symptoms of social phobia. Implications are offered for the cognitive and behavioral treatment of anxiety and related disorders in this population. PMID:26763500

    Dating violence during adolescence negatively influences concurrent psychosocial functioning, and has been linked with an increased likelihood of later intimate partner violence. Identifying who is most vulnerable for this negative outcome can inform the development of intervention practices addressing this problem. The two goals of this study were to assess variations in the prevalence of dating violence across different measures of sexual minority status (e.g., sexual minority identity or same-sex sexual behavior), and to assess whether this association was mediated by bullying, the number of sexual partners, binge drinking or aggressive behaviors. These goals were assessed by employing the Massachusetts Youth Risk Behavior Survey (N = 12,984), a regionally representative sample of youth ages 14-18. In this sample, a total of 540 girls and 323 boys reported a non-heterosexual identity, and 429 girls and 230 boys reported having had one or more same-sex sexual partners. The results generally supported a higher prevalence of dating violence among sexual minority youth. This vulnerability varied considerably across gender, sexual minority identity and the gender of sexual partners, but generally persisted when accounting for the mediating variables. The findings support investigating dating violence as a mechanism in the disparities between sexual minority and heterosexual youth, and the importance of addressing sexual minority youth specifically in interventions targeting dating violence.

    Sexual minority youth (youth who are attracted to the same sex or endorse a gay/lesbian/bisexual identity) report significantly higher rates of depression and suicidality than heterosexual youth. The minority stress hypothesis contends that the stigma and discrimination experienced by sexual minority youth create a hostile social environment that can lead to chronic stress and mental health problems. The present study used longitudinal mediation models to directly test sexual minority-specific victimization as a potential explanatory mechanism of the mental health disparities of sexual minority youth. One hundred ninety-seven adolescents (14-19 years old; 70 % female; 29 % sexual minority) completed measures of sexual minority-specific victimization, depressive symptoms, and suicidality at two time points 6 months apart. Compared to heterosexual youth, sexual minority youth reported higher levels of sexual minority-specific victimization, depressive symptoms, and suicidality. Sexual minority-specific victimization significantly mediated the effect of sexual minority status on depressive symptoms and suicidality. The results support the minority stress hypothesis that targeted harassment and victimization are partly responsible for the higher levels of depressive symptoms and suicidality found in sexual minority youth. This research lends support to public policy initiatives that reduce bullying and hate crimes because reducing victimization can have a significant impact on the health and well-being of sexual minority youth.

    2010-01-01

    This article summarizes data from a qualitative study investigating the ways in which female youth perceive and respond to challenges related to the interplay of late adolescence and a minority sexual orientation. Fifteen sexual minority females in late adolescence were interviewed individually and in focus groups. The interviews focused on participants' perceptions of challenges, the impact those stressors have in their lives, and methods they utilize to cope with them. The most common negative experiences reported were isolation, lack of acceptance, harassment, and violence. Sub-themes include: hearing negative messages about gender and sexual orientation, pressures to conform to a variety of cultural norms including gender norms, fears of future violence, and pressure to identify sexual orientation. Collectively, the participants described these negative consequences of experiences of heterosexism, sexism, and racism as their most difficult experiences. The most common responses to these stressors reported by participants were finding support in relationships, engaging in coping responses, pursuing education and activism, rebellion and resistance, and avoidance and deferment.

    Objective To conduct a systematic review of the literature examining risk factors/correlates of cigarette smoking among lesbian, gay and bisexual (ie, sexual minority) populations. Methods Sets of terms relevant to sexual minority populations and cigarette smoking were used in a simultaneous search of 10 databases through EBSCOhost. The search was limited to the peer-reviewed literature up to January 2011, using no geographic or language limits. For inclusion, the paper was required to: (1) have been written in English, (2) have sexual minorities (defined by either attraction, behaviour, or identity) included in the study population and (3) have examined some form of magnitude of association for risk factors/correlates of any definition of cigarette smoking. A total of 386 abstracts were reviewed independently, with 26 papers meeting all inclusion criteria. Abstracts were reviewed and coded independently by authors JB and JGLL using nine codes derived from the inclusion/exclusion criteria. Results Studies used various measures of sexual orientation and of smoking. Risk factors that could be considered unique to sexual minorities included internalised homophobia and reactions to disclosure of sexual orientation. Some studies also indicated common smoking risk factors experienced at higher rates among sexual minorities, including stress, depression, alcohol use and victimisation. Conclusions This review identified risks that were associated with sexual minority status and common to the general population but experienced at potentially higher rates by sexual minorities. Government and foundation funds should be directed towards research on the origins of this disparity. PMID:22170335

    This study examines the mental health characteristics of sexual minority (lesbian, gay, and bisexual, or LGB) veterans, compared these characteristics to those of an existing Veterans Affairs (VA) sample, and examined the relationship between mental health and anxiety around concealment of LGB identity while in the military. Data regarding LGB veterans' (n = 409) military experiences and current mental health were collected via an online survey; comparison data (n = 15,000) were retrieved from a VA data warehouse. LGB veterans were more likely to screen positive for posttraumatic stress disorder (PTSD), depression, and alcohol problems than the comparison sample. Anxiety around concealment of one's sexual orientation while in the service was related to current depression and PTSD symptoms. PMID:23414280

    Lesbians, gay men, and bisexuals are a sexual minority experiencing elevated cancer risk factors and health disaparites, e.g., elevated tobacco use, disproportionate rates of infection with human immunodeficiency virus. Little attention has been paid to cancer prevention, education, and control in sexual minorities. This study describes cancer risk perceptions and their correlates so as to generate testable hypotheses and provide a foundation for targeting cancer prevention and risk reduction efforts in this high risk population. A cross-sectional survey of affiliates of a large urban community center serving sexual minority persons yielded a study sample of 247 anonymous persons. The survey assessed demographics, absolute perceived cancer risk, cancer risk behaviors, desired lifestyle changes to reduce cancer risk, and psychosocial variables including stress, depression, and stigma. Univariate and multivariate nonparametric statistics were used for analyses. The sample was primarily white non-Hispanic, middle-aged, and > 80% had at least a high school education. Mean values for absolute perceived cancer risk (range 0-100% risk), were 43.0 (SD = 25.4) for females, and for males, 49.3 (SD = 24.3). For females, although the multivariate regression model for absolute perceived cancer risk was statistically significant (P < .05), no single model variable was significant. For men, the multivariate regression model was significant (P < .001), with endorsement of "don't smoke/quit smoking" to reduce personal cancer risk (P < .001), and greater number of sexual partners (P = .054), positively associated with absolute perceived risk for cancer. This study provides novel data on cancer risk perceptions in sexual minorities, identifying correlates of absolute perceived cancer risk for each gender and several potential foci for cancer prevention interventions with this at-risk group.

    Objective Sexual minority (i.e., lesbian, gay, and bisexual) adults smoke cigarettes at higher rates than heterosexual adults. Smoking after receiving a cancer diagnosis is a major health concern, yet risk of continued smoking among sexual minority cancer survivors is as yet unknown. The current study examines current smoking among sexual minority vs. heterosexual adult cancer survivors. Method Data drawn from the 2010 Behavioral Risk Factor Surveillance System survey in five states (Alaska, California, Massachusetts, New Mexico, and Wisconsin) included items about sexual orientation, cancer diagnosis, and tobacco use. The analytic sample included 124 sexual minority and 248 propensity score matched heterosexual adult cancer survivors. Results Bivariate analysis showed that sexual minority cancer survivors had twice the odds of current smoking as their heterosexual counterparts (OR=2.03, 95%CI:1.093.80). In exploratory analyses stratified by sex, sexual minority disparities in prevalence of smoking post-cancer showed a trend toward significance among females, not males. Conclusion The current study offers preliminary evidence that sexual minority status is one variable among many that must be taken into account when assessing health behaviors post-cancer diagnosis. Future research should identify mechanisms leading from sexual minority status to increased rates of smoking and develop tailored smoking cessation interventions. PMID:25984441

    When empirically supported treatments (ESTs) are effectively adapted for use with minority populations, they may be more efficacious. As such, there is a need to adapt existing ESTs for use with diverse sexual and gender minority youth (SGMY). The unique bias-based challenges faced by SGMY require the integration of affirmative practices into ESTs to effectively address the specific needs of this underserved group of youth. The primary purpose of the authors in this article is to present a clearly articulated stakeholder driven model for developing an affirmative adapted version of cognitive behavioral therapy (CBT) for use with diverse SGMY. The authors' approach to adaptation follows the "adapt and evaluate" framework for enhancing cultural congruence of interventions for minority groups. A community based participatory research approach, consistent with a stakeholder driven process, is utilized to develop the intervention from the ground up through the voices of the target community. Researchers conducted 3 focus groups with culturally diverse SGMY to explore salient aspects of youths' cultural and SGM identities in order to inform the intervention and ensure its applicability to a wide range of SGMY. Focus group data is analyzed and integrated into an existing group-based CBT intervention. The following themes emerge as critical to affirmative work with diverse SGMY: (1) the interplay between cultural norms, gender norms, sexual orientation, and gender identity; (2) the complex role of religious community within the lives of SGMY; and (3) consideration of extended family and cultural community as youth navigate their SGM identities.

    Sexual minority adolescents (SMA) experience disparities in health and behavioral health outcomes, including high rates of depression, anxiety, self-harm, substance use, HIV risk behavior, suicidal ideation, and suicide attempts. These outcomes are commonly attributed to minority stress. Stress experiences are different for SMA than their adult counterparts. For example, disclosing their sexual orientation may be more likely to result in homelessness because these youth more often live with parents or other family members. Although stress in this population has been explored in previous research, very little is known about how SMA cope. Relying upon an adolescent coping model, this study examined the coping strategies, responses, and resources of SMA related to stress. Forty-eight racially and ethnically diverse SMA (age 14–19) were recruited for 90-minute tape-recorded interviews. The semi-structured interviews were guided by a life history calendar. Recordings were transcribed verbatim and entered into QSR NVivo. All transcripts were coded by two members of the research team and went through a consensus process. Forty-three unique coping statements emerged that fit with the Compas model of adolescent coping. SMA cope with minority stress in similar ways to heterosexual youth coping with general stress, but findings suggest that SMA may also use different kinds of coping resources. Although further research is needed, the present study identified a variety of ways SMA cope with stress and can inform future research on the development interventions. PMID:26634221

    The current study examined the associations between sexual orientation prototypicality--or the extent to which an individual's attractions or sexual behaviors are similar to others in the same sexual orientation category--and several indicators of well-being (depressive symptoms, loneliness, and self-esteem). Data were analyzed from a sample of 586 self-identified heterosexual and sexual minority (lesbian/gay and bisexual) men and women who completed an online survey. We used k-means cluster analysis to assign individuals to sexual orientation clusters (resulting in heterosexual and sexual minority clusters) based on dimensions of same-sex and other-sex attractions (emotional, romantic, and sexual) and sexual behavior. Sexual orientation prototypicality was operationalized as the Euclidean distance between an individual's position in the cluster and their cluster centroid. Lower sexual orientation prototypicality (i.e., greater Euclidean distance from one's cluster centroid) was significantly associated with higher depressive symptoms, higher loneliness, and lower self-esteem for men and women; results did not significantly differ for self-identified heterosexuals versus sexual minorities. Although self-identified sexual orientation and sexual orientation prototypicality were both associated with well-being for women, only sexual orientation prototypicality was associated with well-being for men. Findings suggest that sexual orientation prototypicality may be a better indicator of well-being than sexual orientation for men. Further, sexual orientation prototypicality appears to play a significant role in well-being for women. PMID:25257258

    Objective To investigate whether past-30 day illicit drug use among sexual minority youth was more common in neighborhoods with a greater prevalence of hate crimes targeting lesbian, gay, bisexual, and transgender (LGBT, or sexual minority) individuals. Methods We used a population-based survey of public school youth in Boston, Massachusetts, consisting of 1292 9th–12th grade students from the 2008 Boston Youth Survey Geospatial Dataset (sexual minority n = 108). Data on LGBT hate crimes involving assaults or assaults and battery between 2005 and 2008 were obtained from the Boston Police Department and linked to youths’ residential address. Youth reported past-30 day use of marijuana and other illicit drugs. Wilcoxon–Mann–Whitney tests and corresponding p-values were computed to assess differences in substance use by neighborhood-level LGBT assault hate crime rate among sexual minority youth (n = 103). Results The LGBT assault hate crime rate in the neighborhoods of sexual minority youth who reported current marijuana use was 23.7 per 100,000, compared to 12.9 per 100,000 for sexual minority youth who reported no marijuana use (p = 0.04). No associations between LGBT assault hate crimes and marijuana use among heterosexual youth (p > 0.05) or between sexual minority marijuana use and overall neighborhood-level violent and property crimes (p > 0.05) were detected, providing evidence for result specificity. Conclusions We found a significantly greater prevalence of marijuana use among sexual minority youth in neighborhoods with a higher prevalence of LGBT assault hate crimes. These results suggest that neighborhood context (i.e., LGBT hate crimes) may contribute to sexual orientation disparities in marijuana use. PMID:24326203

    Background Sexual minority adolescents appear to be at increased risk for internalizing disorders relative to their heterosexual peers, but there is a paucity of research explaining this elevated risk. Emotion regulation deficits are increasingly understood as important predictors of internalizing psychopathology among general samples of adolescents. The present study sought to examine whether deficits in emotion regulation could account for disparities in internalizing symptoms between sexual minority and heterosexual adolescents. Methods The present study utilized longitudinal data from a racially/ethnically diverse (68% non-Hispanic Black and Hispanic/Latino) community sample of 1,071 middle school students (ages 1114). Results Adolescents who endorsed same-sex attraction evidenced higher rates of internalizing symptoms at both time points. Structural equation modeling indicated that sexual minority adolescents exhibited greater deficits in emotion regulation (rumination and poor emotional awareness) than their heterosexual peers. Emotion regulation deficits in turn mediated the relationship between sexual minority status and symptoms of depression and anxiety. Conclusions The results demonstrate the importance of considering normative psychological processes in the development of internalizing symptomatology among sexual minority adolescents, and suggest emotion regulation deficits as specific targets of prevention and intervention efforts with this population. Future studies are needed to determine whether stigma-related stressors are responsible for emotion regulation deficits among sexual minority youth. PMID:18564066

    Objectives. We examined whether lifetime risk of posttraumatic stress disorder (PTSD) was elevated in sexual minority versus heterosexual youths, whether childhood abuse accounted for disparities in PTSD, and whether childhood gender nonconformity explained sexual-orientation disparities in abuse and subsequent PTSD. Methods. We used data from a population-based study (n?=?9369, mean age?=?22.7 years) to estimate risk ratios for PTSD. We calculated the percentage of PTSD disparities by sexual orientation accounted for by childhood abuse and gender nonconformity, and the percentage of abuse disparities by sexual orientation accounted for by gender nonconformity. Results. Sexual minorities had between 1.6 and 3.9 times greater risk of probable PTSD than heterosexuals. Child abuse victimization disparities accounted for one third to one half of PTSD disparities by sexual orientation. Higher prevalence of gender nonconformity before age 11 years partly accounted for higher prevalence of abuse exposure before age 11 years and PTSD by early adulthood in sexual minorities (range?=?5.2%33.2%). Conclusions. Clinicians, teachers, and others who work with youths should consider abuse prevention and treatment measures for gender-nonconforming children and sexual minority youths. PMID:22698034

    Guatemalan gay and bisexual men, men who have sex with men (MSM), and transgender persons carry disproportionate burden of HIV and other sexually transmitted infections compared with other Guatemalan subgroups. However, little is known about the determinants of sexual health to inform health promotion and disease prevention interventions among these sexual minorities. We sought to explore sexual health and HIV risk among Guatemalan sexual minorities, using a community-based participatory research approach. We conducted 8 focus groups (n = 87 participants total) and 10 individual in-depth interviews with gay and bisexual men, MSM, and transgender persons. Using constant comparison, an approach to grounded theory, we analyzed verbatim transcripts and identified 24 themes that we organized into five ecological factors influencing sexual health: intrapersonal (e.g. misconceptions about HIV transmission, low perceived susceptibility and lack of condoms use skills); interpersonal (e.g. family rejection and condom use as a barrier to intimacy); community (e.g. discrimination and stigma); institutional (e.g. limited access to health promotion resources); and public policy (e.g. perceived lack of provider confidentiality and anti-gay rhetoric). There is profound need for multiple-level interventions to ensure that Guatemalan sexual minorities have the knowledge and skills needed to reduce sexual risk. Interventions are warranted to increase social support among sexual minorities, reduce negative perspectives about sexual minorities, develop institutional resources to meet the needs of sexual minorities and reduce harmful anti-gay rhetoric. Understanding and intervening on the identified factors is especially important given that the health of Guatemalan sexual minorities has been to-date neglected. PMID:24688113

    Previous research has indicated that students who identify as lesbian, gay, bisexual, or transgender (LGBT) often have negative experiences on university campuses due to their sexual orientation or gender identity. Direct and indirect experiences contribute to an overall perception of the campus climate. This study used an online survey to assess students' perceptions of campus climate, their experiences confronting bias, support of family members and friends, and whether they had considered leaving campus. Multiple regression analysis indicated that perceptions of poorer campus climate were predicted by greater unfair treatment by instructors, more impact from anti-lesbian, gay, bisexual, transgender, or queer (LGBTQ) bias on friends' and families' emotional support, and having hidden one's LGBT identity from other students. Cluster analyses revealed four groups of participants distinguished by openness about their sexual orientation and negative experiences, with one group appearing to be at risk for poor retention. Results are discussed in terms of the needs of LGBTQ students on campus. PMID:23808345

With a sample of 143 sexual minority people, the present study extended these hypotheses by examining the moderating roles of positive and negative religious coping in the link of 2 sexual minority-specific minority stress variables (heterosexist discrimination, internalized heterosexism) with psychological distress and well-being. In partial support of our hypotheses, we found that positive religious coping moderated the relation of internalized heterosexism and psychological well-being such that greater positive religious coping weakened the deleterious impact of internalized heterosexism on psychological well-being. Negative religious coping did not moderate any links. As the first test of the moderating roles of religious coping styles in the sexual minority stress-psychological distress link, the present study yields important findings for research and practice with religious and spiritual sexual minority individuals.

    Although the population-level success of tobacco denormalization is widely accepted, it remains unclear whether these strategies alleviate health inequities for sexual and gender minorities. The high risk of smoking among sexual and gender minorities together with research that documents a relationship between stigma-related processes and smoking prevalence for these groups raises questions about whether tobacco-related stigma intensifies the disadvantages associated with the stigmas of other social identities. We have not adequately considered how tobacco-related stigma overlaps with other social identity stigmas. Given concerns about the intensification of inequality, this type of inquiry has important implications for understanding both the effectiveness and limitations of tobacco denormalization strategies for sexual and gender minorities and identifying those tobacco prevention, treatment, and public health policies that work to ameliorate health inequities.

    This study examines the effects of different types of sexual expectancies on early sexual behavior among racial/ethnic minority young adolescents. African American and Latino participants between 11 and 13 years old were recruited through schools and community-based agencies in the South Bronx, New York (N = 223). Multiple logistic regression analyses were used to predict early sexual behavior outcomes, which include engagement in sexual possibility situations, kissing, and sexual touching. The moderating effect of gender was examined using multiplicative interaction terms. Higher expectations categorized as personal/parental and romantic/peer expectancies related to the negative consequences of sexual intercourse decreased the odds of engagement in early sexual behavior; whereas higher academic/career and sexual health expectancies did not. Gender moderated the relationships between personal/parental expectancies and engagement in sexual possibility situations and romantic/peer expectancies and kissing. Social workers formulating sexual health promotion and HIV prevention programs for racial/ethnic minority young adolescents should focus on personal/parental and romantic/peer expectancies in favor of negative expectancies regarding academic/career achievement, pregnancy, and HIV. Social work interventions to delay sexual debut should include a family-based component and should be sensitive to gender differences in sexual expectancies. PMID:22461958

Young people 16 to 18 years old (n = 822) were administered surveys assessing demographic characteristics, sexual behaviors, mental health, and parent-child communication. Adjusted multivariate regressions examining correlates of sexual risk revealed that SMYs had more sexual partners than heterosexual youths (B = 3.90; SE = 0.95; P < .001) and were more likely to engage in sex trading (OR = 3.11; CI = 1.12-8.62; P < .05).

    Bisexual people are often implored to "pick a side," implying that bisexuality is both more controllable and less desirable than heterosexuality or homosexuality. Bisexual people's status as a social group perceived to fall between a traditionally advantaged group and a traditionally disadvantaged group may have the potential to clarify lay conceptions of sexual orientation. We examined participants' views of groups varying in sexual orientation by randomly assigning participants (including heterosexual men and women as well as gay men and lesbian women) from four samples to evaluate heterosexual, bisexual, or homosexual targets (N = 1379). Results provided strong evidence for the previously untested theoretical argument that bisexuality is perceived as less stable than heterosexuality or homosexuality. In addition, participants low in Personal Need for Structure rated female (but not male) bisexuality as relatively stable, suggesting that a preference for simple, binary thinking can partially explain a negative conception of an ostensibly "intermediate" identity. Bisexual targets were perceived as falling between heterosexual and homosexual targets in terms of gender nonconformity, and less decisive, less monogamous, and lacking in positive traits that were associated with homosexual targets. In sum, views of bisexual people were both more negative than and qualitatively different from views of gay men and lesbian women. We discuss the results as an illustration of the complex ways that perceivers' attitudes can differ depending on which target groups they are considering, suggesting that intergroup bias cannot be fully understood without attending to social categories viewed as intermediate.

    This study analyzes the prevalence and characteristics of childhood and adolescence sexual abuse suffered by a sample of university students, as well as the variables associated with the nature of abuse. Participants anonymously completed the Questionnaire on Child Sexual Abuse, in order to obtain information about experience of sexual abuse. Of a total of 2,375 students, 289 (12.2%) declared having suffered sexual abuse before the age of 18. The invasiveness, continuity, and severity of abuse was related to the location where the abuse took place (the more severe cases were committed in the homes of the victim and perpetrator) and to the circumstances of abuse (relationships with partners/at a party or while caring for a child predicted more severe abuse). The age of the victim (preschool) and an intrafamilial relationship between victim and perpetrator were also related to more invasive, continuous, and severe sexual abuse. The knowledge of characteristics of perpetrator and victim and the context in which sexual abuse occurs can help to better comprehend the nature and correlates of sexual abuse. The results of the present study may contribute to the design of programs for the prevention of sexual abuse to minors. PMID:22774431

    Purpose Sexual and gender minorities (SGM) smoke cigarettes at higher rates than the general population. Historically, research in SGM health issues was conducted in urban populations and recent population-based studies seldom have sufficient SGM participants to distinguish urban from rural. Given that rural populations also tend to have a smoking disparity, and that many SGM live in rural areas, it is vitally important to understand the intersection of rural residence, SGM identity, and smoking. This study analyzes the patterns of smoking in urban and rural SGM in a large sample. Methods We conducted an analysis of 4280 adult participants in the Out, Proud, and Healthy project with complete data on SGM status, smoking status, and zip code. Surveys were conducted at 6 Missouri Pride Festivals and online in 2012. Analysis involved descriptive and bivariate methods, and multivariable logistic regression. We used GIS mapping to demonstrate the dispersion of rural SGM participants. Results SGM had higher smoking proportion than the non-SGM recruited from these settings. In the multivariable model, SGM identity conferred 1.35 times the odds of being a current smoker when controlled for covariates. Rural residence was not independently significant, demonstrating the persistence of the smoking disparity in rural SGM. Mapping revealed widespread distribution of SGM in rural areas. Conclusion The SGM smoking disparity persists among rural SGM. These communities would benefit from continued research into interventions targeting both SGM and rural tobacco control measures. Recruitment at Pride Festivals may provide a venue for reaching rural SGM for intervention. PMID:26000317

    Homosexuality and transsexuality are still widely viewed by lay individuals as morally negative and deserving of legal proscription. Peer-reviewed data confirm that experiences of legal discrimination are associated with stress-related health problems, reduced utilization of health care, and financial and legal challenges for individuals and families, especially those with children. In the last 3 years, the American Psychiatric Association, American Psychological Association, and American Psychoanalytic Association have each reviewed the research on sexual orientation and identity, and each has confirmed that sexual orientation and gender identity do not correlate with mental illness or immorality. They have each endorsed laws that confer equality to sexual minorities, including nondiscrimination in employment, medical insurance coverage, adoption, and access to civil marriage. The American College of Obstetricians and Gynecologists (ACOG), by virtue of its history of advocacy for women's health, is in a position to promote policy and make similar recommendations, recognizing that sexual minority women's health and their family issues are an integral component of taking care of all women. The College should review the policies of America's premier mental health associations and consider including sexual orientation and gender identity in its own nondiscrimination policy, and ACOG should issue a policy statement in support of laws to provide safety from violence and discrimination, equal employment opportunities, equal health insurance coverage, and equal access to civil marriage.

    The Garfuna, an ethnic minority group in Honduras, have been disproportionately affected by HIV. Previous research suggests that migration and high rates of multiple sexual partnerships are major drivers of the epidemic. Using data from a 2012 population-based survey, we assessed whether temporary migration was associated with (1) multiple sexual partnerships and (2) sexual concurrency among Garfuna men and women in Honduras. Among both men and women, temporary migration in the last year was associated with an increased likelihood of multiple sexual partnerships and with concurrency, though only the association between migration and multiple sexual partnerships among men was statistically significant (Adjusted Prevalence Ratio 1.7, 95 % CI 1.2-2.4). Migration may contribute to HIV/STI vulnerability among Garfuna men and women via increases in these sexual risk behaviors. Research conducted among men and women at elevated risk of HIV should continue to incorporate measures of mobility, including history of internal migration. PMID:26242612

    Objective We examined the direct and indirect impact of minority stress on mental health and substance use among sexual minority women. Method A combination of snowball and targeted sampling strategies was used to recruit lesbian and bisexual women (N = 1,381) for a cross-sectional, online survey. Participants (M age = 33.54 years; 74% White) completed a questionnaire assessing gender expression, minority stressors (i.e., victimization, internalized homophobia, and concealment), social–psychological resources (i.e., social support, spirituality), and health-related outcomes. We used structural equation modeling to test associations among these factors, with gender expression as an antecedent and social–psychological resources as a mediator between minority stress and health. Results The final model demonstrated acceptable fit, χ2(79) = 414.00, p < .05, confirmatory fit index = .93, Tucker–Lewis index = .91, standardized root-mean-square residual = .05, root-mean-square error of approximation = .06, accounting for significant portions of the variance in mental health problems (56%) and substance use (14%), as well as the mediator social–psychological resources (24%). Beyond indirect effects of minority stress on health outcomes, direct links emerged between victimization and substance use and between internalized homophobia and substance use. Conclusions Findings indicate a significant impact of minority stressors and social–psychological resources on mental health and substance use among sexual minority women. The results improve understanding of the distinct role of various minority stressors and their mechanisms on health outcomes. Health care professionals should assess for minority stress and coping resources and refer for evidence-based psychosocial treatments. PMID:21341888

    Sexual minority men and transgender women are disproportionately affected by HIV in Guatemala. Innovative prevention strategies are urgently needed to address these disparities. While social network approaches are frequently used to reach sexual minorities, little is known about the unique network characteristics among sub-groups. We conducted in-depth qualitative interviews with 13 gay-identifying men, eight non-gay-identifying men who have sex with men (MSM) and eight transgender women in Guatemala City. Using narrative and thematic coding procedures, we identified distinct patterns in the size, composition, and overlap between social and sexual networks across groups. Gay-identifying men had the largest, most supportive social networks, predominantly comprising family. For both non-gay-identifying MSM and transgender women, friends and sex clients provided more support. Transgender women reported the smallest social networks, least social support, and the most discrimination. HIV prevention efforts should be tailored to the specific sexual minority population and engage with strong ties. PMID:25418236

    Purpose Very few studies have examined mental disorders among male sexual minority youth. We describe demographic correlates, comorbidity, and history of mental disorders and suicidality in a large sample of male sexual minority youth. Methods Structured diagnostic interviews were conducted with 449 racially diverse, urban sexual minority males, ages 16-20, who were recruited using a social-network driven sampling methodology. Results Lifetime major depressive episode (MDE) affected 33.2% of the youth. Lifetime conduct disorder (23.6%), alcohol abuse/dependence (19.6%), posttraumatic stress disorder (PTSD; 16.0%), and nicotine dependence (10.7%) were also common. Black participants were less likely than White participants to be diagnosed with lifetime MDE, alcohol abuse/dependence, nicotine dependence, suicidal ideation, and anorexia, as well as past 12-month alcohol abuse/dependence (OR's range from .08-.46). Relative to participants identifying as gay, bisexual identified youth were at higher risk for lifetime PTSD (OR=2.04), and participants who did not identify as gay or bisexual were at higher risk for both lifetime and past 12-month nicotine dependence (OR's = 4.36 and 3.46, respectively). Most participants with mental disorders never received treatment, and comorbidity was common. Conclusions MDE, conduct disorder, alcohol abuse/dependence, PTSD, and nicotine dependence are common and infrequently treated in young sexual minority men. Some within-group disparities emerged, suggesting factors related to racial background and self-identification may help to understand resilience to the unique stressors experienced by these young men.

    Background Nepal has experienced sporadic reports of human rights violations among sexual and gender minorities. Our objective was to identify a range of human rights that are enshrined in international law and/or are commonly reported by sexual and gender minority participants in Kathmandu, to be nonprotected or violated. Methods In September 2009 three focus group discussions were conducted by trained interviewers among a convenience sample of sexual and gender minority participants in Kathmandu Nepal. The modified Delphi technique was utilized to elicit and rank participant-generated definitions of human rights and their subsequent violations. Data was analyzed independently and cross checked by another investigator. Results Participants (n = 29) reported experiencing a range of human rights violations at home, work, educational, health care settings and in public places. Lack of adequate legal protection, physical and mental abuse and torture were commonly reported. Access to adequate legal protection and improvements in the family and healthcare environment were ranked as the most important priority areas. Conclusions Sexual and gender minorities in Nepal experienced a range of human rights violations. Future efforts should enroll a larger and more systematic sample of participants to determine frequency, timing, and/or intensity of exposure to rights violations, and estimate the population-based impact of these rights violations on specific health outcomes PMID:22591775

    Research among sexual minorities has traditionally examined problems such as substance use, HIV risk, mental health problems, and victimization. Among sexual minority street-based female sex workers, these vulnerabilities can be magnified. Grounded in theories of resilience, this study examines risk and protective factors associated with a high level of personal mastery among a vulnerable population of women. Data are drawn from baseline interviews from street-based African American female sex workers enrolled in a randomized intervention trial in Miami, Florida. We compare sexual minority (N=197) and heterosexual (N=365) women on measures of risk and protective factors; among sexual minority women we present logistic regression analyses which reveal that severe mental distress and HIV transmission risk are associated with low levels of personal mastery, while protective factors of transportation access and social support are associated with high levels of personal mastery. These findings suggest that these protective factors may potentially facilitate the development of personal mastery and represent beneficial avenues for intervention efforts. PMID:25530691

    Sexual pressure can have detrimental effects to individuals both physically and emotionally; however, research in this area is lacking regarding the experiences by lesbian, gay, bisexual, queer, and questioning (LGBQ) women. This online study qualitatively examined sexual pressure experienced and explained by LGBQ women (n = 50) using grounded theory methodology. Participants responded to open-ended questions by providing perspectives from both those who were on the receiving end of the sexual pressure (recipients) and from those who pressured their partners (initiators). Results indicated that there were eight overarching themes, 43 higher order categories, and 241 line-by-line codes. The eight overarching themes included: Reasons to Not Want Sex, Reasons for Pressuring, Reasons for Giving In, Actions of Initiators, Expectations, Communication, Negative Outcomes, and Positive Reactions. Negative Outcomes was the most common theme endorsed. Several higher order categories indicated the unique experiences of sexual minority women, namely trying to be "normal" (e.g., engaging in sexual acts as a result of internalized homophobia), experiencing more pressure from men, and self-consciousness (specifically related to lack of knowledge about sex with women). Implications for the current study include the importance of addressing sexual pressure with sexual minority women and creating interventions, such as assertiveness training and communication skills, that could assist both recipients and initiators with engaging in mutually satisfactory sexual practices.

    This article describes current knowledge on sexual, mental, and behavioral health of sexual minority (SM) youth and identifies gaps that would benefit from future research. A translational sciences framework is used to conceptualize the article, discussing findings and gaps along the spectrum from basic research on prevalence and mechanisms, to intervention development and testing, to implementation. Relative to adults, there has been much less research on adolescents and very few studies that had longitudinal follow-up beyond one year. Due to historical changes in the social acceptance of the SM community, new cohorts are needed to represent contemporary life experiences and associated health consequences. Important theoretical developments have occurred in conceptualizing mechanisms that drive SM health disparities and mechanistic research is underway, including studies that identify individual and structural risk/protective factors. Research opportunities exist in the utilization of sibling-comparison designs, inclusion of parents, and studying romantic relationships. Methodological innovation is needed in sampling SM populations. There has been less intervention research and approaches should consider natural resiliencies, life-course frameworks, prevention science, multiple levels of influence, and the importance of implementation. Regulatory obstacles are created when ethics boards elect to require parental permission and ethics research is needed. There has been inconsistent inclusion of SM populations in the definition of “health disparity population,” which impacts funding and training opportunities. There are incredible opportunities for scholars to make substantial and foundational contributions to help address the health of SM youth, and new funding opportunities to do so. PMID:25575125

    The present study examined 100 lesbian and gay college students and 100 heterosexual students to determine whether group differences exist in frequency of a range of non-erotic cognitive distractions during sexual activity. Non-erotic cognitive distraction is a descriptive term for both self-evaluative cognitions related to physical performance and body image concerns, as well as additional cognitive distractions (e.g., contracting an STI or emotional concerns) during sexual activity. Participants were matched on gender (96 males and 104 females), age, and ethnicity, and completed questionnaires assessing frequency of non-erotic cognitive distractions during sexual activity, as well as measures of additional variables (trait and body image anxiety, attitudes toward sexual minorities, self-esteem, and religiosity). Results indicated that sexual minorities experienced significantly more cognitive distractions related to body image, physical performance, and STIs during sexual activity than heterosexuals. Regarding gender, men reported more distractions related to STIs than women.

    Enacted stigma has been linked to increased HIV risk behaviours among sexual minority youth, but despite higher rates of HIV and other STIs, there is very little research with Indigenous youth. In this study, secondary analyses of three population-based, school surveys were conducted to explore the associations between HIV risk and enacted stigma among sexual minority Indigenous youth in Canada, the US, and New Zealand. Data were analyzed and interpreted with guidance from Indigenous and sexual minority research team members, Indigenous advisory groups, and community consultations. In all three countries, Indigenous sexual minority youth were more likely to experience enacted stigma (such as bullying, discrimination, exclusion, harassment, or school-based violence) and report increased HIV risk behaviours (such as lack of condom use, multiple sexual partners, pregnancy involvement, and injection drug use) compared to heterosexual peers. Data were analyzed by age, gender, and sexual orientation, and for some groups, higher levels of enacted stigma was associated with higher HIV risk. The findings highlight the need for more research, including identifying protective factors, and developing interventions that focus on promoting resilience, addressing the levels of stigma and homophobic violence in school, and restoring historical traditions of positive status for Indigenous sexual minority people.

  17. "Honk against homophobia": rethinking relations between media and sexual minorities.

    2013-01-01

    The theory of "symbolic annihilation" or "symbolic violence" has been used in academic literature to describe the way in which sexual minorities have been ignored, trivialized, or condemned by the media. This article aims to de-center research from issues of media representation to consider the capacity for minority groups to proactively use new media and its various avenues for interactivity, social networking, and feedback to fight social exclusion. This work suggests that new media has become a space in which the nominally marginal in society may acquire "social artillery"-a term used to describe how sexual minorities utilize their expanding and more readily accessible social connections in digital space to combat instances of homophobia. The research draws on the results of an inquiry into the relation between media and a regional youth social justice group in Australia tackling homophobia. The research demonstrates that the group is becoming increasingly adept and comfortable with using a cross-section of media platforms to fulfill their own objectives, rather than seeing themselves as passive subjects of media representation. This article argues that this sets an example for other socially excluded groups looking to renegotiate their relation with the media in regional areas. PMID:24147586

    Dating in adolescence plays an integral part in the development of sexual and social identities. This process is particularly salient for sexual minority youth who face additional obstacles to their identity formation due to their marginalized status. We investigated the influence of participating in a same-sex relationship (SSR) or an opposite-sex relationship (OSR) on sexual minority youths' psychological well-being (i.e., symptoms of depression, anxiety and internalized homophobia, and self-esteem) in an ethnically-diverse sample of 350 youth (55% male) between the ages of 15-19 years, recruited from three GLBT drop-in centers in the New York City area. Using longitudinal data, we examined youths' SSR and OSR over time. Multivariate regression analyses suggest that involvement in a SSR was positively associated with changes in self-esteem in males, and negatively correlated with changes in internalized homophobia in females. We discuss the implications for positive development in sexual minority adolescent populations. PMID:20535536

  19. Changes in Neighborhood Characteristics and Depression Among Sexual Minority Young Adults

    2014-01-01

    Using the National Longitudinal Study of Adolescent Health, this study examined the relationship between changes in neighborhood characteristics during the transition from adolescence to young adulthood and depression among sexual minority young adults. Previous research has found that neighborhood characteristics influence sexual minority mental health and that sexual minorities are more likely to move to more urban and politically liberal locations. No study to date, however, has examined the impact of changes in neighborhood characteristics on sexual minority depression. The results from this study show that decreases in the percent urban was associated with increased risk of depression and decreases in the percent Republican voters in sexual minoritys neighborhood was associated with decreases in risk of depression. The results suggest that clinicians may want to screen sexual minority youth for recent changes in their neighborhoods to assess if these changes may be related to the onset or exacerbation of depressive episodes.

    Objective Body image disturbance is a common experience for sexual minority men living with HIV, and is associated with poor self-care behaviors. However, to date, no known cohesive theoretical model has been advanced to understand the possible antecedents and outcomes of body image disturbance in this population. Thus, the goal of the current study was to test a biopsychosocial model of body image and self-care behaviors among sexual minority men living with HIV. Methods Participants were 106 gay and bisexual men living with HIV who completed a battery of self-report measures including assessment of body image disturbance, depression, lipodystrophy, appearance orientation, condom use self-efficacy, antiretroviral therapy (ART) adherence, and HIV sexual transmission risk behaviors. Bayesian estimation was employed to assess model fit and direct and indirect pathways within the model. Results The data fit the model well, with all theorized pathways being significant. Lipodystrophy severity and appearance orientation were associated with elevated body image disturbance. In turn, body image disturbance was related to poorer ART adherence and increased HIV sexual transmission risk behaviors, through the mechanisms of elevated depressive symptoms and poor condom use self-efficacy. Conclusions Elevated body image disturbance among sexual minority men living with HIV is associated with important biopsychosocial variables, which in turn are related to poorer ART adherence and increased HIV sexual transmission risk behaviors. Integrative psychosocial interventions addressing co-occurring body image disturbance, depression, and HIV self-care behaviors may be a fruitful area of future clinical practice and research.

    Purpose Our aim was to examine mechanisms underlying the development of sexual health risk behaviors in sexual minority girls (SMGs) and the relation of these mechanisms and sexual risk behaviors to sexual victimization. Methods Data were drawn from the Project on Human Development in Chicago Neighborhoods cohorts aged 15 and 18 (N = 391; 54 SMGs). Results SMGs reported more sexual victimization and steeper positive trajectories of substance misuse over time than heterosexual girls. Growth in alcohol use during adolescence mediated the link between SMG status and past year number of partners, whereas growth in marijuana use mediated the link between SMG status and self-reported sexually transmitted diseases (STDs). Adding unwanted sexual experiences (UWSE) to the models resulted in reduction of significance in the direct or indirect effects from SMG status on the outcomes. UWSE emerged as a robust predictor, directly and indirectly related to past year number of partners via growth in alcohol use. UWSE also directly predicted STD history. Conclusions The increased risk of SMGs for alcohol and marijuana during adolescence, higher rates of sexual partners, and STD diagnosis may also be linked to their significant risk for sexual victimization. Findings highlight the importance of preventive interventions targeting victimization of SMGs. PMID:24534358

    This study characterized sexual orientation identities and sexual fluidity in attractions in a community-based sample of self-identified transgender and gender-nonconforming adults in Massachusetts. Participants were recruited in 2013 using bimodel methods (online and in person) to complete a one-time, Web-based quantitative survey that included questions about sexual orientation identity and sexual fluidity. Multivariable logistic regression models estimated adjusted risk ratios (aRRs) and 95% confidence intervals (95% CIs) to examine the correlates of self-reported changes in attractions ever in lifetime among the whole sample (n = 452) and after transition among those who reported social gender transition (n = 205). The sample endorsed diverse sexual orientation identities: 42.7% queer, 19.0% other nonbinary, 15.7% bisexual, 12.2% straight, and 10.4% gay/lesbian. Overall, 58.2% reported having experienced changes in sexual attractions in their lifetime. In adjusted models, trans masculine individuals were more likely than trans feminine individuals to report sexual fluidity in their lifetime (aRR = 1.69; 95% CI = 1.34, 2.12). Among those who transitioned, 64.6% reported a change in attractions posttransition, and trans masculine individuals were less likely than trans feminine individuals to report sexual fluidity (aRR = 0.44; 95% CI = 0.28, 0.69). Heterogeneity of sexual orientation identities and sexual fluidity in attractions are the norm rather than the exception among gender minority people. PMID:26156113

    The visibility of a stigmatized identity is central in determining how individuals experience that identity. Sexual minority status (e.g., identifying as gay, lesbian, or bisexual) has traditionally been identified as a concealable stigma, compared with race/ethnicity or physical disability status. This conceptualization fails to recognize, however, the strong link between sexual minority status and a visible stigma: gender nonconformity. Gender nonconformity, or the perception that an individual fails to conform to gendered norms of behavior and appearance, is strongly stigmatized, and is popularly associated with sexual minority status. The hypothesis that harassment due to gender nonconformity mediates the association between sexual minority status and depressive symptoms was tested. Heterosexual and sexual minority-identified college and university students (N = 251) completed questionnaires regarding their sexual minority identity, experiences of harassment due to gender nonconformity, harassment due to sexual minority status, and depressive symptoms. A mediational model was supported, in which the association between sexual minority identity and depressive symptoms occurred via harassment due to gender nonconformity. Findings highlight harassment due to gender nonconformity as a possible mechanism for exploring variability in depressive symptoms among sexual minorities. PMID:25621903

    The goal of this study was to evaluate a novel measure of environmental risk factors for bullying among sexual minority youths. Data on lesbian, gay, bisexual, and transgender (LGBT) assault hate crimes were obtained from police records, geocoded, and then linked to individual-level data on bullying and sexual orientation from the 2008 Boston Youth Survey Geospatial Dataset (N = 1,292; 108 sexual minorities). Results indicated that sexual minority youths who reported relational and electronic bullying were more likely to reside in neighborhoods with higher LGBT assault hate crime rates. There was no asso- ciation between LGBT assault hate crimes and bullying among heterosexual youths, pro- viding evidence for specificity to sexual minority youth. Moreover, no relationships were observed between sexual minority bullying and neighborhood-level violent and property crimes, indicating that the results were specific to LGBT assault hate crimes.

    Intolerant attitudes and sexual prejudice against sexual minorities (lesbian, gay, bisexual, and questioning/queer-LGBQ) has been a long-standing global concern. In this article, Chinese attitudes towards sexual minorities are examined with reference to the cultural context in Hong Kong, a place where the East has intermingled with the West for over a century. Chinese sexuality manifested in Hong Kong is a mix of Confucian ideology and Christian thought. Traditional Confucian values of xiao (filial piety) and conventional religious thoughts of Christianity together influence Chinese attitudes towards sexual minorities. Though many governmental policies have been put in place and numerous laws have been enacted to protect the human rights of underprivileged and disadvantaged groups over the past few decades, sexual minorities are frequently being excluded from most of these protections. In Hong Kong, sexual prejudice exists not only among the general public, but also among educators and mental health professionals. Thus, Chinese sexual minorities experience sexual prejudice and minority stress in Hong Kong under unique cultural circumstances. This calls for inclusive policies and an embracing attitude towards sexual minorities so their mental health will not suffer. PMID:26569635

    Many studies, reviews, and meta-analyses have reported elevated mental health problems for sexual minority (SM) individuals. This systematic review provides an update by including numerous recent studies, and explores whether SM individuals are at increased risk across selected mental health problems as per dimensions of sexual orientation (SO), genders, life-stages, geographic regions, and in higher quality studies. A systematic search in PubMed produced 199 studies appropriate for review. A clear majority of studies reported elevated risks for depression, anxiety, suicide attempts or suicides, and substance-related problems for SM men and women, as adolescents or adults from many geographic regions, and with varied SO dimensions (behaviour, attraction, identity), especially in more recent and higher quality studies. One notable exception is alcohol-related problems, where many studies reported zero or reversed effects, especially for SM men. All SM subgroups were at increased risk, but bisexual individuals were at highest risk in the majority of studies. Other subgroup and gender differences are more complex and are discussed. The review supports the long-standing mental health risk proposition for SM individuals, overall and as subgroups. PMID:26552495

    Objectives. We compared the likelihood of childhood sexual abuse (under age 18), parental physical abuse, and peer victimization based on sexual orientation. Methods. We conducted a meta-analysis of adolescent school-based studies that compared the likelihood of childhood abuse among sexual minorities vs sexual nonminorities. Results. Sexual minority individuals were on average 3.8, 1.2, 1.7, and 2.4 times more likely to experience sexual abuse, parental physical abuse, or assault at school or to miss school through fear, respectively. Moderation analysis showed that disparities between sexual minority and sexual nonminority individuals were larger for (1) males than females for sexual abuse, (2) females than males for assault at school, and (3) bisexual than gay and lesbian for both parental physical abuse and missing school through fear. Disparities did not change between the 1990s and the 2000s. Conclusions. The higher rates of abuse experienced by sexual minority youths may be one of the driving mechanisms underlying higher rates of mental health problems, substance use, risky sexual behavior, and HIV reported by sexual minority adults.

    Sexual minority (lesbian and gay, bisexual, mostly heterosexual) individuals are at an increased risk for hazardous drinking than heterosexual individuals, but little is known about the nature of the disparities as adolescents reach adulthood. We used four waves of a nationally representative data set, the National Longitudinal Study of Adolescent Health (Add Health), to examine disparities of hazardous drinking outcomes between sexual minority and heterosexual men and women from adolescence to young adulthood. Participants were 14 to 18 years old at the first assessment (N = 12,379; 53% female) and 27 to 31 years old at the fourth assessment. At the fourth assessment, 13% self-identified as sexual minority individuals, 16% were Hispanic, and 36% were of minority race, including primarily African Americans (60%) and Asian Americans (18%). There were clear hazardous drinking disparities between sexual minority individuals and heterosexual individuals over time. During adolescence, sexual minority individuals, particularly females, reported higher levels of hazardous drinking. As study participants reached adulthood, the magnitude of the hazardous drinking disparities increased among sexual minorities, sexual minority men in particular. Additional research is needed to better understand the developmental mechanisms that underlie the emerging sexual orientation related disparities of hazardous drinking in young adulthood.

    Adolescent school absenteeism is associated with negative outcomes such as conduct disorders, substance abuse, and dropping out of school. Mental health factors, such as depression and anxiety, have been found to be associated with increased absenteeism from school. Sexual minority youth (youth who are attracted to the same sex or endorse a gay, lesbian, or bisexual identity) are a group at risk for increased absenteeism due to fear, avoidance, and higher rates of depression and anxiety than their heterosexual peers. The present study used longitudinal data to compare sexual minority youth and heterosexual youth on excused and unexcused absences from school and to evaluate differences in the relations between depression and anxiety symptoms and school absences among sexual minority youth and heterosexual youth. A total of 108 14- to 19-years-old adolescents (71% female and 26% sexual minority) completed self-report measures of excused and unexcused absences and depression and anxiety symptoms. Compared to heterosexual youth, sexual minority youth reported more excused and unexcused absences and more depression and anxiety symptoms. Sexual minority status significantly moderated the effects of depression and anxiety symptoms on unexcused absences such that depression and anxiety symptoms were stronger predictors of unexcused absences for sexual minority youth than for heterosexual youth. The results demonstrate that sexual minority status and mental health are important factors to consider when assessing school absenteeism and when developing interventions to prevent or reduce school absenteeism among adolescents.

    Previous research indicates that lesbian, gay, and bisexual (LGB) adolescents are at increased risk for substance use, including heightened rates of marijuana use. Minority stress theory suggests that difficult social situations create a state of chronic stress that leads to poor health outcomes for LGB adults; however, the applicability of this model has not been well explored in relation to substance use among LGB adolescents. The current study is a secondary analysis of the OutProud survey, conducted in 2000. The original study used purposive sampling to collect data from 1,911 LGB adolescents (age 12-17) across the United States, and represents the largest known study to explore experiences specific to identifying as LGB, such as homophobia and gay-related victimization. We used structural equation modeling (SEM) to explore the feasibility of applying a minority stress framework to understand marijuana use in this population. The final structural model for marijuana use in the LGB adolescent sample displayed excellent fit and modest explanatory power for marijuana use. Two of the five factors, community connectedness and internalized homophobia, were significantly (p < .05) associated with marijuana use. Findings suggest that minority stress theory may be appropriately applied to marijuana use in this population; however, better measurement of minority stress concepts for LGB adolescents is needed.

    2014-01-01

    Research on mental health disparities between sexual minority individuals and heterosexuals has traditionally taken a disorder-by-disorder approach. Recently developed trans-diagnostic approaches provide a new method to frame such investigations; however, trans-diagnostic factors have yet to be applied to sexual minority mental health disparities research. The current study applied this methodology to investigate mental health disparities between lesbian, gay, bisexual, and heterosexual individuals in a large national probability sample (N = 34,653). Twelve-month diagnoses of 13 common mood, anxiety, substance use, and personality disorders were modeled, and multi-group analysis indicated a sexual orientation-invariant trans-diagnostic latent structure. Significant disparities at the latent trans-diagnostic factor level were observed; these factor-level disparities are manifested as observed mental disorder disparities. Gender differences typically seen in trans-diagnostic research were not present between sexual minority women and men. Trans-diagnostic internalizing and externalizing factors were then used as outcomes in a minority stress framework and were positively predicted by lifetime history of sexual orientation-related minority stressors (i.e., discrimination and victimization). Implications for using trans-diagnostic approaches to frame intervention efforts, supplement disorder-by-disorder disparities methodologies, and synthesize piecemeal disparities literatures are discussed.

    Sexual minority individuals are at an elevated risk for depression compared to their heterosexual counterparts, yet less is known about how depression status varies across sexual minority subgroups (i.e., mostly heterosexuals, bisexuals, and lesbians and gay men). Moreover, studies on the role of young adult gender nonconformity in the relation between sexual orientation and depression are scarce and have yielded mixed findings. The current study examined the disparities between sexual minorities and heterosexuals during young adulthood in concurrent depression near the beginning of young adulthood and prospective depression 6 years later, paying attention to the diversity within sexual minority subgroups and the role of gender nonconformity. Drawn from the National Longitudinal Study of Adolescent Health (N = 9421), we found that after accounting for demographics, sampling weight, and sampling design, self-identified mostly heterosexual and bisexual young adults, but not lesbians and gay men, reported significantly higher concurrent depression compared to heterosexuals; moreover, only mostly heterosexual young adults were more depressed than heterosexuals 6 years later. Furthermore, while young adult gender nonconforming behavior was associated with more concurrent depression regardless of sexual orientation, its negative impact on mental health decreased over time. Surprisingly, previous gender nonconformity predicted decreased prospective depression among lesbians and gay men whereas, among heterosexual individuals, increased gender nonconformity was not associated with prospective depression. Together, the results suggested the importance of investigating diversity and the influence of young adult gender nonconformity in future research on the mental health of sexual minorities.

    Immigrant Sexual minority Latino men—who may or may not self-identify as gay—constitute a minority within a minority. Often labeled “hidden” and “hard-to-reach,” and marginalized along multiple dimensions, it is a sub-group about whom little is known. Informed by a Social Ecological Framework, we sought to describe key social variables for 190 such men in rural North Carolina and to test associations with three sexual outcomes: consistent condom use, number of sex partners, and sexual compulsivity. Participants reported limited English-language use, predominantly Latino close friends, middle levels of social support despite numerous social ties, and frequent experiences of discrimination. There were unique sets of correlates for each sexual outcome. Findings may inform health promotion interventions and guide future research. PMID:24344629

    We examined differences between sexual minority women's (SMW's) sexual identity and sexual behavior or sexual attraction as potential contributors to hazardous drinking across a 10-year period. Data are from a longitudinal study examining drinking and drinking-related problems in a diverse, community-based sample of self-identified SMW (Wave 1: n = 447; Wave 2: n = 384; Wave 3: n = 354). Longitudinal cross-lagged models showed that SMW who report higher levels of identity-behavior or identity-attraction discordance may be at greater risk of concurrent and subsequent hazardous drinking. Results of multigroup models suggest that sexual orientation discordance is a more potent risk factor for risky drinking outcomes among SMW in older adulthood than in younger adulthood. Findings support that discordance between sexual orientation dimensions may contribute to hazardous drinking among SMW and provide evidence that cognitive-behavioral consistency is important for individuals expressing diverse and fluid sexual identities, attraction, and behavior.

    The purpose of this study was to determine if sexual minority students in supportive school environments experienced fewer depressive symptoms and lower rates of suicide ideation, plans and attempts ("suicidality") than sexual minority students in less supportive school environments. In 2007, a nationally representative sample (N=9,056) of students from 96 high schools in New Zealand used Internet tablets to complete a health and well-being survey that included questions on sexual attractions, depressive symptoms, and suicidality. Students reported their experience of supportive environments at school and gay, lesbian, bisexual, and transgender (GLBT) bullying, and these items were aggregated to the school level. Teachers (n=2,901) from participating schools completed questionnaires on aspects of school climate, which included how supportive their schools were toward sexual minority students. Multilevel models were used to estimate school effects on depressive symptoms and suicidality controlling for background characteristics of students. Sexual minority students were more likely to report higher levels of depressive symptoms and suicidality than their opposite-sex attracted peers (p<.001). Teacher reports of more supportive school environments for GLBT students were associated with fewer depressive symptoms among male sexual minority students (p=.006) but not for female sexual minority students (p=.09). Likewise in schools where students reported a more supportive school environment, male sexual minority students reported fewer depressive symptoms (p=.006) and less suicidality (p<.001) than in schools where students reported less favorable school climates. These results suggest that schools play an important role in providing safe and supportive environments for male sexual minority students. PMID:25469988

    This study reviewed the public notification policy of sexual offenders against minors in South Korea as compared to community notification programs in the United States. The study then examined the policy's impact on increasing the general public's awareness of such sexual crimes. This is based on the assumption that heightening public awareness can be a starting point in combating such crimes. Results of the data, drawn from a sample of 1,409 Koreans across the nation, showed that the notification policy enhanced public awareness. Factors related to this increase in awareness were people's concern about or familiarity with the policy and people's experience in identifying the existence of known sexual offenders in their communities. Based on the results of this study, strategies for enhancing public awareness of sexual crimes on minors were formulated. The need to develop treatment programs for sexual offenders was likewise highlighted. PMID:15983053

    Myriad health inequities that sexual minority youths (SMYs) experience have been documented over the past several decades. Evidence demonstrates that these are not a result of intrinsic characteristics; rather, they result from high levels of adversity that SMYs experience. Despite the pervasive marginalization that SMYs face, there is also evidence of great resilience within this population. It seems likely that if a culture of marginalization produces health inequities in SMYs, a culture of acceptance and integration can work to produce resiliencies. We have described how promoting forms of acceptance and integration could work to promote resilient SMYs despite an overarching culture of marginalization. Building on SMYs’ resiliencies may potentiate the effectiveness of health promotion interventions to reduce health disparities within this population. PMID:24328652

    Openness and self-exploration have been associated with myriad benefits. Within the realm of sexuality, sexual exploration may be 1 facet of openness and self-exploration that yields benefits. Prior literature suggests that such exploration may have benefits for sexual orientation minority persons, though limited research has investigated the benefits of sexual exploration for heterosexuals. The present study used data from 346 adult women (185 exclusively heterosexual, 161 not exclusively heterosexual) to investigate the role of sexual exploration as a mediator between sexual orientation status and positivity toward sex. Results of a structural equation modeling analysis supported mediation of the relationship between sexual orientation and sexual positivity via sexual exploration. Implications for future research and clinical interventions are presented. PMID:26380352

  11. Sexual discourses and strategies among minority ethnic youth in the Netherlands.

    2014-01-01

    This study explores the way minority ethnic youth in the Netherlands evaluate their sexual experiences, how they frame these experiences in different sexual discourses and how they deal with conflicts between different sexual discourses, both at home and in Dutch society. During 46 narrative interviews, Dutch young people (aged 12-22 years) from different minority ethnic communities shared their sexual histories and their dreams for the future relating to love and sexuality. Different sexual discourses can be identified in the language they used to describe their ideas and their experiences. Young people grow up with a variety of discourses but actively re-shape them according to circumstances and need. In many cases, young people experience a conflict between the discourses of the home and those that are prevalent more generally in Dutch society. Young people's ways of negotiating these contradictory discourses comprise four main strategies: (1) conforming to parents' values, (2) breaking up with parents, (3) leading a double life and (4) integrating competing discourses. By bringing together different sexual discourses and acknowledging diverse strategies, sexual health policies can become more effective in promoting sexual health for minority ethnic youth. Findings from the study add fuel to debate on understanding (sexual) agency among young people, exhibiting the social 'embeddedness' of individual agency. PMID:24902033

    Despite legislative advances in terms of workplace equality for sexual and gender minorities (SGM), available data ascertains the persistence of workplace discrimination of lesbian, gay, bisexual, and especially of transgender/transsexual employees. This article, based on an extensive literature review, explores the relationship between different types of workplace discrimination experiences and their impacts on the mental health of SGM and of different sub-populations: men who have sex with men, non-heterosexual women, lesbian and gay parents, and trans people. Furthermore, the article explores certain individual and systemic protection and risk factors that have an impact on this relationship, such as coming-out at work and organisational support. Finally, the existing literature on workplace discrimination and mental health of sexual and gender minorities highlights the importance, in the current legal and social context, of intersectional approaches and of research on homo- and trans-negative microaggressions. The article ends with a discussion on the implications for practice, research, and workplace settings, as well as with several recommendations for these settings. PMID:26966853

  13. Sexual health of ethnic minority MSM in Britain (MESH project): design and methods

    2010-01-01

    Background Men who have sex with men (MSM) remain the group most at risk of acquiring HIV infection in Britain. HIV prevalence appears to vary widely between MSM from different ethnic minority groups in this country for reasons that are not fully understood. The aim of the MESH project was to examine in detail the sexual health of ethnic minority MSM living in Britain. Methods/Design The main objectives of the MESH project were to explore among ethnic minority MSM living in Britain: (i) sexual risk behaviour and HIV prevalence; (ii) their experience of stigma and discrimination; (iii) disclosure of sexuality; (iv) use of, and satisfaction with sexual health services; (v) the extent to which sexual health services (for treatment and prevention) are aware of the needs of ethnic minority MSM. The research was conducted between 2006 and 2008 in four national samples: (i) ethnic minority MSM living in Britain; (ii) a comparison group of white British MSM living in Britain; (iii) NHS sexual health clinic staff in 15 British towns and cities with significant ethnic minority communities and; (iv) sexual health promotion/HIV prevention service providers. We also recruited men from two "key migrant" groups living in Britain: MSM born in Central or Eastern Europe and MSM born in Central or South America. Internet-based quantitative and qualitative research methods were used. Ethnic minority MSM were recruited through advertisements on websites, in community venues, via informal networks and in sexual health clinics. White and "key migrant" MSM were recruited mostly through Gaydar, one of the most popular dating sites used by gay men in Britain. MSM who agreed to take part completed a questionnaire online. Ethnic minority MSM who completed the online questionnaire were asked if they would be willing to take part in an online qualitative interview using email. Service providers were identified through the British Association of Sexual Health and HIV (BASHH) and the Terrence Higgins Trust (THT) CHAPS partnerships. Staff who agreed to take part were asked to complete a questionnaire online. The online survey was completed by 1241 ethnic minority MSM, 416 men born in South and Central America or Central and Eastern Europe, and 13,717 white British MSM; 67 ethnic minority MSM took part in the online qualitative interview. In addition 364 people working in sexual health clinics and 124 health promotion workers from around Britain completed an online questionnaire. Discussion The findings from this study will improve our understanding of the sexual health and needs of ethnic minority MSM in Britain. PMID:20630087

    Researchers have examined perceived discrimination as a risk factor for depression among sexual minorities; however, the role of religion as a protective factor is under-investigated, especially among sexual minority youth. Drawing on a cross-sectional study investigating campus climate at a large public university in the U.S. Midwest, we examined the role of affiliation with a gay-affirming denomination (i.e., endorsing same-sex marriage) as a moderating factor in the discrimination-depression relationship among self-identified sexual minority (n = 393) and heterosexual youth (n = 1,727). Using multivariate linear regression analysis, religious affiliation was found to moderate the discrimination-depression relationship among sexual minorities. Specifically, the results indicated that the harmful effects of discrimination among sexual minority youth affiliated with denominations that endorsed same-sex marriage were significantly less than those among peers who affiliated with denominations opposing same-sex marriage, as well as those among peers who identified as secular. In contrast, religious affiliation with gay-affirming denominations did not moderate the discrimination-depression relationship among heterosexual participants. The findings suggest that although religion and same-sex sexuality are often seen as incompatible topics, it is important when working with sexual minority clients for clinicians to assess religious affiliation, as it could be either a risk or a protective factor, depending on the religious group’s stance toward same-sex sexuality. To promote the well-being of sexual minority youth affiliated with denominations opposed to same-sex marriage, the results suggest these faith communities may be encouraged to reconsider their position and/or identify ways to foster youth’s resilience to interpersonal discrimination.

    In the USA, end-stage liver disease (ESLD) is a major cause of morbidity and mortality among ethnic minorities. Ethnic populations vary with respect to chronic liver disease prevalence, access to transplantation, and therapeutic outcomes post liver transplantation. These ethnic differences present unique challenges to healthcare professionals involved in the care of patients with chronic liver disease prior and post transplantation. This review will discuss the variations and challenges of liver transplantation in the ethnic minority population. PMID:19390965

    Sexual minorities have higher rates of depression and anxiety than their heterosexual counterparts. This elevated risk of psychological distress has generally been hypothesized to be a result of the effects of discrimination including internalized negative beliefs about sexual minorities. However, little research has examined the role of various types of coping in mediating between internalized homophobia and mental health. We tested the direct relationship between internalized homophobia and psychological distress and evaluated general and sexual minority-specific coping strategies as potential mediators using structural equation modeling. Data are from a national sample of 1,099 young adult sexual minority women who were on average 20.86 (SD= 2.12) years old, participating in a study on mental health and substance use. The model demonstrated acceptable fit, χ2 (83) = 402.9, p <.001, CFI=.94, TLI=.92, SRMR= .07, and RMSEA=.06, accounting for 73% of variance in psychological distress. Greater use of maladaptive coping and less use of sexual minority-specific coping were associated with higher psychological distress. Although maladaptive coping mediated the relationship between internalized homophobia and psychological distress, sexual minority-specific coping did not. Our findings support previous studies that have demonstrated the impact of internalized homophobia on psychological distress as well as the role of coping as a protective/risk factor in this relationship.

    In sexual population, recombination reshuffles genetic variation and produces novel combinations of existing alleles, while selection amplifies the fittest genotypes in the population. If recombination is more rapid than selection, populations consist of a diverse mixture of many genotypes, as is observed in many populations. In the opposite regime, which is realized for example in the facultatively sexual populations that outcross in only a fraction of reproductive cycles, selection can amplify individual genotypes into large clones. Such clones emerge when the fitness advantage of some of the genotypes is large enough that they grow to a significant fraction of the population despite being broken down by recombination. The occurrence of this ‘clonal condensation’ depends, in addition to the outcrossing rate, on the heritability of fitness. Clonal condensation leads to a strong genetic heterogeneity of the population which is not adequately described by traditional population genetics measures, such as linkage disequilibrium. Here we point out the similarity between clonal condensation and the freezing transition in the random energy model of spin glasses. Guided by this analogy we explicitly calculate the probability, Y, that two individuals are genetically identical as a function of the key parameters of the model. While Y is the analog of the spin-glass order parameter, it is also closely related to rate of coalescence in population genetics: two individuals that are part of the same clone have a recent common ancestor.

    Research consistently demonstrates that sexual minority status is associated with increased risk of problematic substance use. Existing literature in this area has focused on group-specific minority stress factors (e.g., victimization and internalized heterosexism). However, no known research has tested the incremental validity of personality traits as predictors of substance use beyond identified group-specific risk factors. A sample of 704 sexual minority adults was recruited nationally from lesbian, gay, bisexual, transgender, queer, and questioning community organizations and social networking Web sites and asked to complete an online survey containing measures of personality, sexual minority stress, and substance use. Hierarchical regression models were constructed to test the incremental predictive validity of five-factor model personality traits over and above known sexual minority risk factors. Consistent with hypotheses, extraversion and conscientiousness were associated with drug and alcohol use after accounting for minority stress factors, and all factors except agreeableness were associated with substance use at the bivariate level of analysis. Future research should seek to better understand the role of normal personality structures and processes conferring risk for substance use among sexual minorities.

    Discrimination has been linked to negative health outcomes among minority populations. The increasing evidence regarding health disparities among sexual minorities has underscored the importance of addressing sexuality discrimination as a public health issue. We conducted a web-based survey between May and September of 2012 in order to obtain a diverse sample of young men who have sex with men (ages 18-29; N = 397; 83% gay; 49% Black, 27% White, 15% Latino) living in the Detroit Metro Area (Michigan, USA). Using multivariate regression models, we examined the association between overall health (self-rated health, days in prior month when their physical or mental health was not good, limited functionality) and experiences of sexuality-based work discrimination. Fifteen percent reported at least one experience of sexuality-based work discrimination in the prior year. Recent workplace discrimination was associated with poorer self-rated health, a greater number of days when health was not good, and more functional limitation. We discuss the importance of addressing sexuality-related discrimination as a public health problem and propose multilevel intervention strategies to address these discriminatory practices.

    BACKGROUND Testing, refining, and tailoring theoretical approaches that are hypothesized to reduce sexual risk behaviors among adolescent subpopulations is an important task. Relatively little is known about the relationship between components of the information-motivation-behavior (IMB) model and sexual behaviors among underage minority youth. Using the IMB model, this study examines predictors of risky sexual behavior among underserved Hispanic and African-American youth. METHODS This cross-sectional study was conducted with a sample of 380 youths aged 1117 years recruited in Los Angeles, California, and utilized latent variable models to examine interrelationships and predictive relations among IMB model variables associated with risky sexual behavior. RESULTS Sixty percent of the participants aged 1517 and 1 out of 10 participants aged 1112 reported prior sexual intercourse. Of the sexually active, more than half reported having unprotected sex and 11% had sexual intercourse with 4 or more partners. Results of the structural equation model indicated that older age and attitudes against sexual activities had significant, direct impacts on risky sexual behaviors. Behavioral refusal skills, positioned as an intervening variable, also significantly predicted less risky sex. Knowledge, attitudes against sexual activities, and perceived peer pressure against sexual behavior predicted sexual refusal skills. Additionally, there were significant indirect effects on risky sexual behavior mediated through behavioral refusal skills. CONCLUSION A large number of disadvantaged minority urban youth are engaged in risky sexual behaviors. Intervention programs, particularly those targeting preadolescents, should focus on building long-lasting behavioral skills that emphasize the reduction of peer pressure and normative influences on risky sexual behaviors. Components of the IMB model clearly have a role in the design of efficacious interventions. PMID:20573141

    Background Sexual minority youth are more likely to smoke cigarettes than heterosexuals but research into the determinants of these disparities is lacking. Purpose To examine whether exposure to structural stigma predicts cigarette smoking in sexual minority youth. Methods Prospective data from adolescents participating in the Growing Up Today Study (20002005). Results Among sexual minority youth, living in low structural stigma states (e.g., states with non-discrimination policies inclusive of sexual orientation) was associated with a lower risk of cigarette smoking after adjustment for individual-level risk factors (Relative Risk[RR]=0.97, 95% Confidence Interval[CI]: 0.96, 0.99, p=0.02). This association remained marginally significant after additional controls for potential state-level confounders (RR=0.97, 95% CI: 0.93, 1.00, p=0.06). In contrast, among heterosexual youth, structural stigma was not associated with past-year smoking rates, documenting specificity of these effects to sexual minority youth. Conclusions Structural stigma represents a potential risk factor for cigarette smoking among sexual minority adolescents. PMID:24136092

    Sexual minority youth are at risk for negative school-based experiences and poor academic outcomes. Yet, little is known about their experiences in positive school-based contexts. Using the National Longitudinal Study of Adolescent Health (1,214 sexual minority and 11,427 heterosexual participants), this study compared participation rates in, predictors of, and outcomes associated with three types of school-based extracurricular activities - sports, arts, and school clubs - by sexual orientation and gender. Findings revealed several significant sexual orientation and gender differences in participation rates in school-based sports, clubs, and arts activities. Further, findings suggested that the outcomes associated with extracurricular activity involvement do not differ by sexual orientation and gender; however, predictors of participation in these domains varied across groups.

    Little is known about risk/protective factors for sexually coercive behavior in general population youth. We used a Swedish school-based population survey of sexual attitudes and experiences (response rate 77%) and investigated literature-based variables across sexually coercive (SEX), non-sexual conduct problem (CP), and normal control (NC) participants to identify general and specific risk/protective factors for sexual coercion. Among 1,933 male youth, 101 (5.2%) reported sexual coercion (ever talked or forced somebody into genital, oral, or anal sex) (SEX), 132 (6.8%) were classified as CP, and the remaining 1,700 (87.9%) as NC. Of 29 tested variables, 25 were more common in both SEX and CP compared to NC youth, including minority ethnicity, separated parents, vocational study program, risk-taking, aggressiveness, depressive symptoms, substance abuse, sexual victimization, extensive sexual experiences, and sexual preoccupation. When compared to CP youth only, SEX youth more often followed academic study programs, used less drugs and were less risk-taking. Further, SEX more frequently than CP youth reported gender stereotypic and pro-rape attitudes, sexual preoccupation, prostitution, and friends using violent porn. Finally, in a multivariate logistic regression, academic study program, pro-rape attitudes, sexual preoccupation, and less risk-taking independently remained more strongly associated with SEX compared to CP offending. In conclusion, several sociodemographic, family, and individual risk/protective factors were common to non-sexual and sexually coercive antisocial behavior in late adolescence. However, pro-rape cognitions, and sexual preoccupation, were sexuality-related, specific risk factors. The findings could inform preventive efforts and the assessment and treatment of sexually coercive male youth. PMID:19888644

    The Gaoshan minority constitutes about 2% of Taiwan's population, and the total Gaoshan minority is estimated to have a population of 400,000. Most of them live on the island's west coast, in the central mountains, and eastern valleys. The birth rate of the Gaoshan minority is slightly higher than that of the average population, but its death rate is about two to three times above average. From 1949 to 1979, the population growth rate for the Gaoshan minority was about 79%. Close to 97% of the population is made up of young people and only 3% are old people. There are more males than females, and the age for marriage is generally young. The timespan of childbearing for the female is comparatively long. The educational and cultural levels of the Gaoshan minority are low. Most of the people earn their living by engaging in agriculture, together with additional activities in fishing and hunting; approximately 75% of the working people belong to this category. Only 14% are people who are working in industry, mining, commerce, and the transportation business. About 11% work in other professions. In recent years, the average income from agriculture and animal husbandry has gradually decreased, and the income from industrial wages and business has shown an obvious increase. PMID:12159334

    This study examined the impact of various traumas across the life span on screening positive for current posttraumatic stress disorder (PTSD) and depression among heterosexual and sexual minority women veterans. Women veterans were recruited over the Internet (N = 706, 37% lesbian or bisexual) to participate in an anonymous, online survey. We assessed childhood trauma; adult sexual assault and adult physical victimization before, during, and after the military; combat exposure; perceived sexist discrimination during military service; sexual minority military stressors; past-year sexist events; and whether participants screened positive for PTSD or depression. Binary logistic regressions were used to generate odds ratios and 95% confidence intervals for PTSD and depression, stratified by sexual orientation and controlling for demographic characteristics. Lesbian and bisexual women reported higher rates of trauma across the life span, although in some instances (e.g., sexual assault during and after military service, combat exposure), they did not differ from their heterosexual counterparts. Childhood trauma and traumas that occurred during military service added the most variance to both PTSD and depression models. Sexual assault during military service appeared to be especially harmful with respect to screening positive for PTSD for both sexual orientation groups. Results revealed a number of other predictors of mental health status for women veterans, some of which differed by sexual orientation. Findings indicate a significant burden of interpersonal trauma for both heterosexual and lesbian/bisexual women veterans and provide information on the distinct association of various traumas with current PTSD and depression by sexual orientation.

  17. An ecological framework for sexual minority women's health: factors associated with greater body mass.

    In recent years, many studies have focused on the body of sexual minority women, particularly emphasizing their larger size. These studies rarely offer theoretically based explanations for the increased weight, nor study the potential consequences (or lack thereof) of being heavier. This article provides a brief overview of the multitude of factors that might cause or contribute to larger size of sexual minority women, using an ecological framework that elucidates upstream social determinants of health as well as individual risk factors. This model is infused with a minority stress model, which hypothesizes excess strain resulting from the stigma associated with oppressed minority identities such as woman, lesbian, bisexual, woman of color, and others. We argue that lack of attention to the upstream social determinants of health may result in individual-level victim blaming and interventions that do not address the root causes of minority stress or increased weight.

    2015-05-01

    Prior research shows that health disparities exist between sexual minority and heterosexual individuals. We extend the literature by testing if the higher prevalence of childhood victimization experienced by sexual minority individuals accounts for lifetime health disparities. Heterosexual (n=422) and sexual minority (n=681) participants were recruited on-line in North America. Respondents completed surveys about their childhood victimization experiences (i.e., maltreatment by adults and peer victimization) and lifetime physician-diagnosed physical health conditions. Results showed that sexual minority individuals experienced higher prevalence of childhood victimization and lifetime physical health problems than heterosexuals. Mediation analyses indicated that maltreatment by adults and peer bullying explained the health disparities between sexual minority individuals and heterosexuals. This study is the first to show that multiple childhood victimization experiences may be one pathway to explain lifetime physical health disparities. Intervention programs reducing the perpetration of violence against sexual minority individuals are critical to reduce health care needs related to victimization experiences. PMID:25864147

    Lesbian, gay, and bisexual (i.e., sexual minority) populations have increased prevalence of both self-injurious and suicidal behaviors, but reasons for these disparities are poorly understood. Objective To test the association between socially-based stressors (e.g., victimization, discrimination) and self-injurious behavior, suicide ideation, and suicide attempt. Participants A national sample of college-attending 18- to 24-year-olds. Methods Random or census samples from post-secondary educational institutions that administered the National College Health Assessment during the Fall 2008 and Spring 2009 semesters. Results Sexual minorities reported more socially-based stressors than heterosexuals. Bisexuals exhibited greatest prevalence of self-injurious and suicidal behaviors. In adjusted models, intimate partner violence was most consistently associated with self-injurious behaviros. Conclusions Sexual minorities' elevated risks of self-injurious and suicidal behaviors may stem from higher exposure to socially-based stressors. Within-group differences among sexual minorities offer insight to specific risk factors that may contribute to elevated self-injurious and suicidal behaviors in sexual minority populations.

    Introduction: Sexual and gender minority individuals (i.e., lesbian, gay, bisexual, and transgender [LGBT]) have a higher smoking prevalence than nonminority individuals. There is limited evidence of smoking abstinence success in nontailored smoking treatments among LGBT smokers. Methods: This study is a secondary data analysis comparing the efficacy of extended, nontailored treatments among sexual and gender minority and nonminority smokers. Data from two clinical trials were combined to increase power and generalizability of the findings. Trials began with 12 weeks of counseling, nicotine replacement, and bupropion, after which participants were randomized to an extended treatment. Results: Follow-up occurred at weeks 12, 24, 52, 64, and 104. Of the sample (n = 777), 17% identified as sexual and gender minority and 83% as nonminority. The sample was 75% non-Hispanic White, with 86% completing at least some college, and 68% were employed. Sexual and gender minorities were younger and indicated a greater desire to quit smoking than nonminority smokers. No other differences emerged on demographic, smoking, or mood variables. The average Fagerstrm Test for Nicotine Dependence score was 4.8, and mean daily cigarettes was 19.8. The generalized estimating equations model revealed no significant differences in abstinence between sexual and gender minority smokers and nonminority smokers at all follow-up assessments. Conclusions: Sexual and gender minority smokers appear as likely to quit or abstain as nonminority smokers in extended, nontailored interventions. However, these findings may not generalize to other geographic areas, where access to treatment is limited or a higher stigma of sexual orientation exists. PMID:24727483

    To obtain reliable information on commercial sexual exploitation of minor girls under the age of 21, a multifocal, exploratry and prospective using a questionnaire was undertaken in Cameroon. This investigation was initiated and funded by the Cercle International pour la Promotion de la Création (CIPCRE) and carried out by the Cameroon Society for the Prevention of Child Abuse and Neglect (CASPCAN). The survey was performed during the last quarter of year 2004 in four major cities of Cameroon, i.e. Yaoundé, Douala, Bamenca and Bafoussam. Of the 800 questionnaires that were distributed, 722 were considered as suitable for analysis (90.3%). A total of 291 minor girls were victims of commercial sexual exploitation, i.e., 40% of the population studied. The mean age of the victims was 16.6 years (range, 9-20 years). The main reason given for entering prostitution was poverty. The victims were fairly well educated but the level of instruction was not sufficient to find a job paying an income comparable to prostitution. Many were from large families (mean, 7.1 children). The victims' family was monogamous in 40.2% of cases, polygamous in 24.4%, and monoparental in 35.4%. Eighty percent of the victims already had run away from home at least once due to problems in their families ranging from severe corporal punishment (25.8%) and mistreatment linked to parental alcohol and drug abuse to forced early marriage (27.5%) and intrafamilial sexual abuse. A large proportion of the victims (36.4%) were mothers who could not attend school and could not find work. Many victims were completely neglected by their own parents with 43.4% of parents being aware of the activities of their daughters but only 10.6% being opposed to it. Most (78.5%) had good knowledge of the risk of HIV and used condoms regular. These results confirms the general hypothesis of the authors that commercial exploitation of minor girls is widespread in Cameroon. The authors recommend development of a national program to combat this plight. PMID:19499745

    The purpose of this study was to estimate the 6-month incidence rates of sexual assault, physical dating violence (DV), and unwanted pursuit (e.g., stalking) victimization among sexual-minority (i.e., individuals with any same-sex sexual experiences) college students with comparison data from non-sexual-minority (i.e., individuals with only heterosexual sexual experiences) college students. Participants (N = 6,030) were primarily Caucasian (92.7%) and non-sexual-minority (82.3%). Compared with non-sexual-minority students (N-SMS; n = 4,961), sexual-minority students (SMS; n = 1,069) reported significantly higher 6-month incidence rates of physical DV (SMS: 30.3%; N-SMS: 18.5%), sexual assault (SMS: 24.3%; N-SMS: 11.0%), and unwanted pursuit (SMS: 53.1%; N-SMS: 36.0%) victimization. We also explored the moderating role of gender and found that female SMS reported significantly higher rates of physical DV than female N-SMS, whereas male SMS and male N-SMS reported similar rates of physical DV. Gender did not moderate the relationship between sexual-minority status and victimization experiences for either unwanted pursuit or sexual victimization. These findings underscore the alarmingly high rates of interpersonal victimization among SMS and the critical need for research to better understand the explanatory factors that place SMS at increased risk for interpersonal victimization.

    2009-01-01

    Sexual minorities are at increased risk for multiple mental health burdens compared to heterosexuals. The field has identified two distinct determinants of this risk, including group-specific minority stressors and general psychological processes that are common across sexual orientations. The goal of the present paper is to develop a theoretical framework that integrates the important insights from these literatures. The framework postulates that (a) sexual minorities confront increased stress exposure resulting from stigma; (b) this stigma-related stress creates elevations in general emotion dysregulation, social/interpersonal problems, and cognitive processes conferring risk for psychopathology; and (c) these processes in turn mediate the relationship between stigma-related stress and psychopathology. It is argued that this framework can, theoretically, illuminate how stigma adversely affects mental health and, practically, inform clinical interventions. Evidence for the predictive validity of this framework is reviewed, with particular attention paid to illustrative examples from research on depression, anxiety, and alcohol use disorders.

    Female injection drug users (IDU) who report sex with women are at increased risk for HIV and social instability, but it is important to assess whether these disparities also exist according to sexual minority identity rather than behaviorally defined categories. Within a sample of current IDU in Baltimore, about 17% of female study participants (n=307) identified as gay/lesbian/bisexual. In controlled models, sexual minorities were three times as likely to report sex exchange behavior and four times as likely to report a recent STI. Injection risk did not differ significantly, but sexual minority women reported higher prevalence of socio-economic instability, negative health indicators, and fewer network financial, material, and health support resources. There is a need to identify and address socio-economic marginalization, social support, and health issues among female IDUs who identify as lesbian or bisexual. PMID:25504312

    Although research on disclosure following intimate partner violence (IPV) victimization is burgeoning, sexual minority young adults' (lesbian, gay, bisexual, queer, questioning, etc.; LGBQ+) experiences have not received equal attention. The current study employed the minority stress framework to examine disclosure experiences of LGBQ+ college students across the United States reporting physical IPV victimization within their current relationship (n = 77). Participants completed measures assessing minority stress and IPV disclosure, and answered open-ended questions regarding the most and least helpful persons/responses to disclosure or reasons for non-disclosure. Results indicated that approximately one-third (35 %) of victims disclosed to at least one person, with friends being the most common recipients. Thematic analyses indicated that talking or listening to the victim was considered the most helpful response and not understanding the situation least helpful. Reasons for non-disclosure centered on themes of the victims' perception that the IPV was not a big deal. Quantitative findings regarding physical IPV disclosure indicated that non-disclosers experienced greater minority stress than disclosers. The current study suggests the presence of differences between sexual minority (i.e., LGBQ +persons) and non-sexual minority persons, as well as between LGBQ+ young adults/college students and older adults and presents a theoretical structure (i.e., minority stress framework) through which these differences may be understood.

    Sexual minority youth report higher rates of depression and suicidality than do heterosexual youth. Little is known, however, about whether these disparities continue as youth transition into young adulthood. The primary goals of this study were to describe and compare trajectories of adolescent depressive symptoms and suicidality among sexual minority and heterosexual youth, examine differences in depressive symptoms and suicidality trajectories across sexual orientation subgroups, and determine whether there are gender differences in these longitudinal disparities. Four waves of data from the National Longitudinal Study of Adolescent Health were analyzed using latent curve modeling (N = 12,379; 53% female). Results showed that the rates of depressive symptoms and suicidality in early adolescence were higher among sexual minority youth than among heterosexual youth, and that these disparities persisted over time as participants transitioned into young adulthood. Consistent with previous cross-sectional studies, the observed longitudinal disparities were largest for females and for bisexually-identified youth. Sexual minority youth may benefit from childhood and early adolescent prevention and intervention programs. PMID:23784511

    Few studies explore sexual minority womens experiences and perceptions of alcohol. Qualitative interviews were conducted with six sexual minority women who reported having sought help for alcohol problems in the past and six who did not. Themes emerged in two broad areas: stressors that contributed to heavy or problem drinking and factors that enhanced coping and reduced both stress and problem use. Alcohol use across groups was framed in terms of social context (e.g., bar patronage), stress management, and addiction. The findings of the study underscore the importance of considering the role of alcohol in managing stress as well coping factors that may inform social service interventions. PMID:22228984

Bisexuals reported riskier substance use behaviors, lower levels of guilt-proneness, and higher levels of internalized heterosexism than gay men and lesbians. Furthermore, study findings indicated that shame and internalized heterosexism are related. Additional investigations of these associations would supplement current understanding of sexual minority stress and would advance the development of substance-related intervention and prevention efforts targeting sexual minorities.

    Identity development is a critical task of adolescence and occurs across multiple areas of self identification. Though research on the identity development process among individuals who are ethnic and sexual minorities has been conducted for individuals who have one minority status or the other, few studies have examined these processes in persons who are both ethnic and sexual minorities. This qualitative study examined the dual identity development processes related to ethnic and sexual identity among gay/bisexual/questioning (GBQ) Latino and African American male adolescents. Results indicated that the processes associated with the development of sexual orientation and ethnic identity occur concurrently. However, the actual processes involved with the development of each identity not only differed, but seemed to be independent of each other since neither process was referenced in the development of the other. Overall, the process of ethnic identity development involved the process of becoming aware of one’s ethnic and cultural heritage, while sexual identity development involved finding one’s own personally relevant sexual orientation label and connecting to that community. The implications of these findings for the development of interventions to assist in the healthy development of GBQ adolescents are discussed. PMID:19594249

    2015-01-01

    We examined differences between sexual minority women’s (SMW’s) sexual identity and sexual behavior or sexual attraction as potential contributors to hazardous drinking across a 10-year period. Data are from a longitudinal study examining drinking and drinking-related problems in a diverse, community-based sample of self-identified SMW (Wave 1: n = 447; Wave 2: n = 384; Wave 3: n = 354). Longitudinal cross-lagged models showed that SMW who report higher levels of identity-behavior or identity-attraction discordance may be at greater risk of concurrent and subsequent hazardous drinking. Results of multigroup models suggest that sexual orientation discordance is a more potent risk factor for risky drinking outcomes among SMW in older adulthood than in younger adulthood. Findings support that discordance between sexual orientation dimensions may contribute to hazardous drinking among SMW and provide evidence that cognitive-behavioral consistency is important for individuals expressing diverse and fluid sexual identities, attraction, and behavior.

    Prior research has reported that many Americans hold prejudicial attitudes toward sexual and gender minorities. Most of this research analyzed attitudes toward target categories in isolation and not in relation to attitudes toward heterosexuals. In addition, most previous research has not examined attitudes of members of sexual and gender minority categories toward other categories. While some research has examined the influence of religiosity on attitudes toward sexual and gender minorities, none of these studies has examined religiosity while also examining the influence of spirituality. In this article we drew on insights from queer theory to examine attitudes toward heterosexual, gay, lesbian, bisexual, and transgender individuals, as well as individuals who practice polygamy, among college students. Three samples gathered over a four-year period (2009, 2011, 2013) at a private, nonsectarian, midsized urban university in the Southeastern United States were used. We found that heterosexuals had the most positive rating, followed in order of rating by gay/lesbian, bisexual, and transgender individuals, and then those who practice polygamy. Regression analyses revealed gender and race were significant predictors of attitudes toward various sexual and gender categories. Holding a literalistic view of the Bible and self-identifying as more religious were related to more negative views toward sexual minorities, while self-identifying as more spiritual was related to more positive views.

    Objective To propose a theoretical model and clinical approach to sexual minority patients who consult mental health professionalsMethods Clinicians at the McGill University Sexual Identity Center (MUSIC) who have been treating patients from various sexual minorities for more than 15 years present useful theoretical constructs of gender and sexuality as well as guidelines for the evaluation and treatment of patients consulting for discomfort or confusion surrounding their sexual orientation, their gender identity or both, based on both the current literature and their clinical experience.Results The notions of non-binary construction of gender, of social determinism of gender roles and expression, and of gender creativity are presented. Sexual orientation is divided into four most commonly used dimensions (emotional attraction, physical attraction, behaviour and identity); the fluidity of these and their potential non-concordance are described. The fact that attraction to one gender is independent of attraction to another gender is highlighted. An attitude of openness to all forms of gender expression and sexual orientation constellations is encouraged to allow the patient free exploration of the several facets of their sexuality.Various domains to explore in evaluating sexual orientation and gender as well as therapeutic avenues are proposed. Areas to enquire about include: mental, physical and social experiences of gender, eroticism and sexual fantasies towards all genders, emotional attraction towards them, sexual and romantic experiences, comfort and certainty about one's identity and about disclosing it.Psychoeducation can be used to teach about sexual diversity and to assess the risks and benefits of coming out to self, family, friends, co-workers or strangers. Cognitive strategies can be undertaken to debunk homophobic and transphobic myths which may fuel poor self-esteem. Psychodynamic approaches can be used to heal the narcissistic wounds of homophobia that may lead one to be mistrustful of authority figures or to suppress sexual feelings when emotional attachment becomes important. Some of these dynamic patterns are rooted in past reactions to parental homophobia and the compromises sexual minorities made as children in order to preserve their relationships with their parents. For youth coming out in present times, family support is crucial to well-being and can be enhanced through family therapy. In mixed orientation couples, couple therapy can help both spouses adapt to the coming out of one of the partners and find a new partnership. Group therapy is useful for many of the above issues particularly as it provides a sense of community which is often lacking in minority groups, especially when individuals and their families do not share the same minority status.Conclusion With the proposed framework and an attitude of openness to sexual diversity, clinicians should feel competent to treat sexual minority patients.

Most research with LBQ women, however, has focused on measuring prevalence of sexual violence rather than its association with health

    Using a representative national sample (N = 20,745), this article explores health and mental health needs, service use, and barriers to services among sexual minority youths (SMYs) and heterosexual peers. SMYs were defined by ever having a same-sex romantic attraction or having a recent same-sex romantic relationship or sexual partner. SMYs accounted for 7.5 percent of the sample. Data were analyzed to ascertain prevalence of risks and explore group differences. Compared with peers, SMY self-reports indicated higher prevalence rates on all indicators of health and mental health need. SMYs reported more sexual activity, more sexually transmitted disease diagnoses, a higher perceived risk for HIV/AIDS, and more forgone medical care than peers.Also compared with peers, SMYs reported higher levels of anxiety depression, suicidality, and physical and sexual victimization and higher rates of unmet mental health need. SMYs also reported greater concerns about confidentiality and were less likely to use school-based services.The majority of SMYs reported same-sex attraction only. Social work and other helping professionals should incorporate same-sex attraction questions into assessment protocols to target services for this population. School- and office-based providers must consider whether their services are welcoming and offer sufficient assurances of confidentiality to facilitate access by SMYs. PMID:21936333

    1995-04-01

    Disproportionate exposure of minority groups to environmental hazards has been attributed to ``environmental racism`` by some authors, without systematic investigation of the factors underlying this exposure pattern. This study examines regional differences in the proximity of African-Americans, Hispanics, Asians, and non-Hispanic Whites to a broad range of facility types and explores the effects of urban and income factors. A statistically significant inverse relationship is found between the percentage of non-Hispanic Whites and virtually all facility categories in all regions. Except for Hispanics in the South, all such associations for minority groups show a direct relationship, though some are nonsignificant. The geographic concentration of facilities is more closely tied to urbanization than to economic factors. Controlling for both urban and economic factors, minority population concentration is still a significant explanatory variable for some facility types in some regions. This finding is most consistent for African-Americans.

    PubMed Central

    Doyle, David Matthew; Molix, Lisa

    2015-01-01

    Work on structural stigma shows how public policy affects health outcomes for members of devalued groups, including sexual minorities. In the current research, structural stigma is proposed as a moderating variable that strengthens deleterious associations between perceived discrimination and social relationship functioning. Hypotheses were tested in two cross-sectional studies, including both online (N = 214; Study 1) and community (N = 94; Study 2) samples of sexual minority men and women residing throughout the United States. Structural stigma was coded from policy related to sexual minority rights within each state. Confirming hypotheses, support for the moderating role of structural stigma was found via multilevel models across studies. Specifically, associations between perceived discrimination and friendship strain, loneliness (Study 1) and familial strain (Study 2) were increased for those who resided in states with greater levels of structural stigma and attenuated for those who resided in states with lesser levels. In Study 1, these results were robust to state-level covariates (conservatism and religiosity), but conservatism emerged as a significant moderator in lieu of structural stigma in Study 2. Results are discussed in the context of the shifting landscape of public policy related to sexual minority rights within the United States. PMID:26807046

    Objectives. We examined whether sexual minority students living in states and cities with more protective school climates were at lower risk of suicidal thoughts, plans, and attempts. Methods. Data on sexual orientation and past-year suicidal thoughts, plans, and attempts were from the pooled 2005 and 2007 Youth Risk Behavior Surveillance Surveys from 8 states and cities. We derived data on school climates that protected sexual minority students (e.g., percentage of schools with safe spaces and Gay–Straight Alliances) from the 2010 School Health Profile Survey, compiled by the Centers for Disease Control and Prevention. Results. Lesbian, gay, and bisexual students living in states and cities with more protective school climates reported fewer past-year suicidal thoughts than those living in states and cities with less protective climates (lesbians and gays: odds ratio [OR] = 0.68; 95% confidence interval [CI] = 0.47, 0.99; bisexuals: OR = 0.81; 95% CI = 0.66, 0.99). Results were robust to adjustment for potential state-level confounders. Sexual orientation disparities in suicidal thoughts were nearly eliminated in states and cities with the most protective school climates. Conclusions. School climates that protect sexual minority students may reduce their risk of suicidal thoughts. PMID:24328634

    2015-07-01

    Previous research suggests that sexual minorities are at greater risk for trauma exposure, mental health problems, and substance use. To date, few studies have examined racial/ethnic differences among sexual minorities in relation to health-related behaviors and outcomes. Furthermore, studies of racial/ethnic differences among young adult sexual minority women (SMW) are virtually nonexistent. The current study adds to the previous literature by exploring differences in trauma exposure, sexual identity, mental health, and substance use in a nonprobability national sample of young adult SMW. A total of 967 self- identified lesbian and bisexual women were recruited via the Internet using social networking sites to participate in a larger longitudinal study on young women's health behaviors. The present study included 730 (76%) White, 108 (10%) African American, 91 (9%) Latina, and 38 (4%) Asian women ages 18 to 25 years. Results revealed differences in socioeconomic variables, degree of outness to family, childhood sexual assault, and forcible rape, but not overall lifetime trauma exposure. Among mental health and health-related behavior variables, few differences between groups emerged. Our findings indicate that both researchers and clinicians should turn their attention to processes of resilience among young SMW, particularly young SMW of color. PMID:25642782

    2014-01-01

    International surveys of victims show crime rates in England and Wales, including hate crimes, are among the highest in Europe. Nevertheless, sexual minority status is a less considered risk factor in general victimization research. This study used sexual minority status and sex to predict victimization across British Crime Surveys from 2007-2010. Logistic regression analyses showed sexual minority status groups were more likely than heterosexuals to be victimized from any and some specific crimes. However, bisexuals rather than lesbians or gay men were more consistently victimized, notably by sexual attacks and within the household. Implications for understanding victimization among these groups are discussed. PMID:24972149

    2013-05-01

    According to recent census reports, nearly a million veterans have a same-sex partner, yet little is known about them or their use of Veterans Health Care Administration (VHA) services. Gay, lesbian, and bisexual (GLB) veterans recruited from the community (N = 356) completed an on-line survey to assess their rates of VHA utilization and whether they experience specific barriers to accessing VHA services. Andersen's model of health care utilization was adapted to provide an analytic and conceptual framework. Overall, 45.5% reported lifetime VHA utilization and 28.7% reported past-year VHA utilization. Lifetime VHA health care utilization was predicted by positive service connection, positive screen for both posttraumatic stress disorder (PTSD) and depression, and history of at least one interpersonal trauma during military service related to respondent's GLB status. Past-year VHA health care utilization was predicted by female gender, positive service connection, positive screen for both PTSD and depression, lower physical functioning, a history of military interpersonal trauma related to GLB status, and no history of stressful experiences initiated by the military to investigate or punish GLB status. Rates of VHA utilization by GLB veterans in this sample are comparable to those reported by VHA Central Office for all veterans. Of those who utilized VHA services, 33% reported open communication about their sexual orientation with VHA providers. Twenty-five percent of all participants reported avoiding at least one VHA service because of concerns about stigma. Stigma and lack of communication between GLB veterans and their providers about sexual orientation are areas of concern for VHA. PMID:23730965

    Equality for sexual and gender minorities (SGMs)-including members of the lesbian, gay, bisexual, and transgender communities-has become an integral part of the national conversation in the United States. Although SGM civil rights have expanded in recent years, these populations continue to experience unique health and health care disparities, including poor access to health care, stigmatization, and discrimination. SGM trainees and physicians also face challenges, including derogatory comments, humiliation, harassment, fear of being ostracized, and residency/job placement discrimination. These inequities are not mutually exclusive to either patients or providers; instead, they are intertwined parts of a persistent, negative culture in medicine toward SGM individuals.In this Perspective, the authors argue that SGM physicians must lead this charge for equality by fostering diversity and inclusion in medicine. They posit that academic medicine can accomplish this goal by (1) modernizing research on the physician workforce, (2) implementing new policies and programs to promote safe and supportive training and practice environments, and (3) developing recruitment practices to ensure a diverse, competent physician workforce that includes SGM individuals.These efforts will have an immediate impact by identifying and empowering new leaders to address SGM health care reform, creating diverse training environments that promote cultural competency, and aligning medicine with other professional fields (e.g., business, law) that already are working toward these goals. By tackling the inequities that SGM providers face, academic medicine can normalize sexual and gender identity disclosure and promote a welcoming, supportive environment for everyone in medicine, including patients.

    2015-01-01

    The health needs of the lesbian, gay, bisexual, and transgender (LGBT) population are traditionally overlooked by the health care community and are rendered invisible by most nursing school curricula. Initial contact with a nurse during a health history and assessment can have an impact on whether the person will feel comfortable disclosing his or her identity, returning for services, or following plans of care. Because the first interaction with a nurse can be critical, the health assessment course is an appropriate place in the curriculum to discuss the needs of the LGBT community. This article includes a discussion of unique health risks to the LGBT population, benefits, and challenges of incorporating these issues into the classroom and recommendations for including the care of this population into a health assessment nursing course. Specific communication techniques are provided that may be helpful during history taking and physical examination with a patient who is LGBT. Guidance regarding physical examination of the transgender patient is also included. These suggestions will be helpful to nurse faculty who teach health assessment, nursing students, educators who design and implement professional development and continuing education for established nurses, preceptors in the clinical setting, and any nurse who is unfamiliar with the needs and concerns specific to the LGBT population.

    2013-01-01

    Objective: Sexual-minority women are at heightened risk for a number of mental health problems, including hazardous alcohol consumption, depression, and anxiety. We examined self-medication and impaired-functioning models of the associations among these variables and interpreted results within a life course framework that considered the unique social stressors experienced by sexual-minority women. Method: Data were from a sample of 384 women interviewed during the first two waves of the Chicago Health and Life Experiences of Women (CHLEW) study. Results: Covariance structure modeling revealed that (a) consistent with a self-medication process, anxiety was prospectively associated with hazardous drinking and (b) consistent with an impaired-functioning process, hazardous drinking was prospectively associated with depression. Conclusions: Our findings support a life course perspective that interprets the mental health of adult sexual-minority women as influenced by adverse childhood experiences, age at drinking onset, first heterosexual intercourse, and first sexual identity disclosure, as well as by processes associated with self-medication and impaired functioning during adulthood.

    2014-01-01

    Introduction: We conducted a longitudinal evaluation of factors associated with persistent smoking behaviors among sexual minority women (SMW; lesbians and bisexual women). Methods: Structured interview data were collected as part of a larger longitudinal study of SMWs health: the Chicago Health and Life Experiences of Women study. We conducted multivariate analyses to evaluate the influence of 4 groups of predictor variables on smoking: (a) demographic, (b) childhood victimization, (c) other substance use, and (d) health variables. Results: At Wave 1, 30.9% (n = 138) of participants reported current smoking, with substance-use and demographic factors having the strongest relationships to smoking status. The majority (84.9%) of Wave 1 smokers were also smoking at Wave 2. Among demographic variables, level of education was inversely associated with continued smoking. With respect to substance use, hazardous drinking and cocaine/heroin use were significantly associated with continued smoking. None of the victimization or health variables predicted smoking status. Conclusions: Consistent with previous studies, smoking rates in this sample of SMW were elevated. Despite intensive efforts to reduce smoking in the general population, 84% of SMW smokers continued smoking from Wave 1 to Wave 2. Findings suggest that the majority of SMW will continue to smoke over time. Additional research is needed to increase motivation and access to smoking cessation resources. PMID:24727370

    Objective To examine the development of muscularity and weight concerns among heterosexual and sexual minority males in adolescence. Method Participants were 5,868 males from the Growing Up Today Study, a US prospective cohort spanning ages 925 years. Generalized estimating equations were used to test sexual orientation differences in the development of muscularity concerns, weight gain attempts, and weight and shape concern. Results Desire for bigger muscles increased slightly each year across adolescence (? =.10, 95% C.I.= .09, .11) regardless of sexual orientation, but gay and bisexual participants reported greater desire for toned muscles than completely and mostly heterosexual males (?=.39, 95% C.I.=.21, .57). Desire for toned muscles did not change with age. Attempts to gain weight increased three-fold across adolescence, with up to 30% reporting weight gain attempts by age 16. Although underweight males (the smallest weight status class) were most likely to attempt to gain weight, most of the observed weight gain attempts were by healthy (69%) and overweight/obese (27%) males, suggesting that most attempts were medically unnecessary and could lead to overweight. Sexual minority participants were 20% less likely to report weight gain attempts than completely heterosexual participants. Weight and shape concern increased with age, with gay and bisexual participants experiencing a significantly greater increase than heterosexual males. Conclusions Sexual orientation modifies the development and expression of male weight and muscularity concerns. The findings have implications for early interventions for the prevention of obesity and eating disorder risk in heterosexual and sexual minority males. PMID:23316852

    Research suggests that community involvement is integral to solving public health problems, including involvement in clinical trials-a gold standard. Significant racial/ethnic disparities exist in the accrual of participants for clinical trials. Location and cultural aspects of clinical trials influence recruitment and accrual to clinical trials. It is increasingly necessary to be aware of defining characteristics, such as location and culture of the populations from which research participants are enrolled. Little research has examined the effect of location and cultural competency in adapting clinical trial research for minority and underserved communities on accrual for clinical trials. Utilizing embedded community academic sites, the authors applied cultural competency frameworks to adapt clinical trial research in order to increase minority participation in nontherapeutic cancer clinical trials. This strategy resulted in successful accrual of participants to new clinical research trials, specifically targeting participation from minority and underserved communities in metropolitan Washington, DC. From 2012 to 2014, a total of 559 participants enrolled across six nontherapeutic clinical trials, representing a 62% increase in the enrollment of blacks in clinical research. Embedding cancer prevention programs and research in the community was shown to be yet another important strategy in the arsenal of approaches that can potentially enhance clinical research enrollment and capacity. The analyses showed that the capacity to acquire cultural knowledge about patients-their physical locales, cultural values, and environments in which they live-is essential to recruiting culturally and ethnically diverse population samples.

  11. Sexual conflict and antagonistic coevolution across water strider populations.

    2012-02-01

    Microevolutionary studies have demonstrated sexually antagonistic selection on sexual traits, and existing evidence supports a macroevolutionary pattern of sexually antagonistic coevolution. Two current questions are how antagonistic selection within-populations scales to divergence among populations, and to what extent intraspecific divergence matches species-level patterns. To address these questions, we conducted an intraspecific comparative study of sexual armaments and mating behaviors in a water strider (Gerris incognitus) in which male genitals grasp resistant females and female abdominal structures help ward off males. The degree of exaggeration of these armaments coevolves across species. We found a similar strong pattern of antagonistic coevolution among populations, suggesting that sexual conflict drives population differentiation in morphology. Furthermore, relative exaggeration in armaments was closely related to mating outcomes in a common environment. Interestingly, the effect of armaments on mating was mediated by population sexual size dimorphism. When females had a large size advantage, mating activity was low and independent of armaments, but when males had a relative size advantage, mating activity depended on which sex had relatively exaggerated armaments. Thus, a strong signal of sexually antagonistic coevolution is apparent even among populations. These results open opportunities to understand links between sexual arms races, ecological variation, and reproductive isolation. PMID:22276547

    Attempting to avoid some of the most common methodological problems involved in research on sexual child abuse, we collected data on crimes, perpetrators, and sanctions in all convicted cases of sexual child abuse in a defined population during a 5-year period. This approach provided amply documented and ascertained cases with precise definitions and descriptions of the crimes involved, no clinical referral bias, and minimal dependence on memory effects. The results are valid for the small proportion of cases that lead to conviction in the context of Swedish legislation. Structured data were collected from the court dossiers in all cases of sexual crimes against minors (less than 15 years of age) tried and sentenced at the courts in the Vstra Gtaland region of Sweden between 1993 and 1997. The total number of 496 sentences for sexual crimes during the study period included 203 cases of sexual child abuse (40.8%) with 283 victims and 196 perpetrators, all men. Girls were victims in 85% of the cases, boys in 12%, and boys as well as girls in 3%. Sexual penetration had occurred in 54.5% of cases and the total proportion of hands-on crimes was 83%. Most perpetrators, 72%, were well known to the child. The most severe offenses took place within the family. A wide range of acts were classified as sexual child abuse, but most common was sexual penetration of a female child by her biological father or a family friend. PMID:11501297

    For a number of years, analyses of minority household energy demand have been supported by the United States Department of Energy (DOE), Office of Economic Impact and Diversity (formerly the Office of Minority Economic Impact). The intention of these analyses has been to characterize patterns of energy demand by various demographic, regional and socioeconomic groups and to develop analytical tools to assess the distributive impact of energy prices and policy on these groups. The model supports strategic objectives outlined by the Department of Energy to explicitly recognize and promote equity in state public utility commission decisions and to assess the potential impact of federal and state energy policy on demographically diverse groups as reported in the Department`s Annual Energy Outlook and the upcoming National Energy Policy Plan. The legislation mandating the Office of Economic Impact and Diversity had been premised on the assumption that patterns of energy demand for minority households are different from the population as a whole. Determining the validity of this premise and its potential economic impact on different population groups has been a major objective of these analyses. Consequently, the recripriocal impacts of energy policy on demographic groups and energy consumption and expenditure dynamics on policy formulation and strategy is a central objective of these studies. Residential energy demand research has been substantial in the past twenty years. Insightful and useful research has been done in this area. However, none of this research has addressed the potential differences in the residential energy demand structure among various population groups. Recent work does compare energy and electricity demand elasticities for non-Latino Whites, with the demand elasticities for Latinos and Blacks. This research is particularly important for examination of questions related to the economic welfare implications of national energy policy.

    2015-01-01

    Mental health disparities between sexual minority and other youth have been theorized to result in part from the effects of the stigmatization on social integration. Stochastic actor-based modeling was applied to complete network data from two high schools in the National Longitudinal Study of Adolescent Health (Mage =15years, N=2,533). Same-sex attracted youth were socially marginalized in a smaller predominantly White school but not in a larger, more racially diverse school. For both schools, homophily was a critical network feature, and could represent social support for and social segregation of such youth. These findings emphasize the school context in studying the social lives of sexual minority youth and suggest that youth may be better off socially in larger and more diverse schools. PMID:25689110

    A heterosexist campus climate can increase risk for mental health problems for sexual minority students; however, the relationship between campus climate for sexual minorities and academic outcomes remains understudied. Using a sample of sexual minority respondents extracted from a campus climate survey conducted at a large university in the Midwest, we examine relationships between multiple dimensions of psychological and experiential campus climate for sexual minorities with academic integration (academic disengagement, grade-point average [GPA]) and social integration (institutional satisfaction, acceptance on campus). We also investigate the protective role of engagement with informal academic and peer-group systems. Findings suggest campus climate affects sexual minority students' integration. In multivariate analyses, perceptions of whether lesbian, gay, and bisexual (LGB) people could be open about their sexual identity was positively associated with acceptance on campus; personal heterosexist harassment was positively associated with academic disengagement and negatively with GPA. Students' informal academic integration (instructor relations) and informal social integration (LGB friends) demonstrated influential main effects but did not moderate any ofthe climate-outcome relationships. Researchers should further explore the relationships between climate and academic outcomes among sexual minority students, both collectively and among specific sub-groups, and address the role of other protective factors.

    We show that a simple model of an evolving sexual population, which dates back to some of the earliest work in theoretical population genetics, exhibits an unexpected and previously unobserved phase transition between ordered and disordered states. This behavior is not present in populations evolving asexually without recombination and is thus important in any comparison of sexual and asexual populations. In order to calculate the details of the phase transition, we use techniques from statistical physics. We introduce the correlation of the population as the order parameter of the system and use maximum entropy inference to find the state of the population at any time.

    Objectives. We examined sexual orientation status differences in alcohol use among youths aged 13 to 18 years or older, and whether differences were moderated by sex, age, or race/ethnicity. Methods. We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys and conducted weighted analyses, adjusting for complex design effects. We operationalized sexual orientation status with items assessing sexual orientation identity, sexual behavior, sexual attraction, or combinations of these. Results. Compared with exclusively heterosexual youths, sexual-minority youths were more likely to report each of the primary study outcomes (i.e., lifetime and past-month alcohol use, past-month heavy episodic drinking, earlier onset of drinking, and more frequent past-month drinking). Alcohol-use disparities were larger and more robust for (1) bisexual youths than lesbian or gay youths, (2) girls than boys, and (3) younger than older youths. Few differences in outcomes were moderated by race/ethnicity. Conclusions. Bisexual youths, sexual-minority girls, and younger sexual-minority youths showed the largest alcohol-use disparities. Research is needed that focuses on identifying explanatory or mediating mechanisms, psychiatric or mental health comorbidities, and long-term consequences of early onset alcohol use, particularly frequent or heavy use, among sexual-minority youths.

    Men who have sex with men (MSM) in India are a hidden and largely understudied population, and have an HIV prevalence 17 times higher than that of the general Indian population. Experiences of social marginalization and negative psychosocial conditions occur concurrent to HIV risk among Indian MSM. To better understand the contextual variables driving HIV risk and inform intervention development, five focus groups (n = 46) and nine key informant interviews were conducted with 55 MSM in Chennai in 2010. NVivo software was used to code the transcripts, and data were analyzed using qualitative descriptive analysis methodology. Participants described sources of psychological distress and low self-worth related to gender non-conformity and sexual minority status. These included stigma from society, pressure to marry, lack of familial acceptance, childhood sexual abuse, and the imperative to keep sexual minority status a secret. Participants' personal evaluations revealed that self-acceptance may be an important resilience factor that can shield these psychosocial and HIV risk factors. In promoting health-seeking behavioral changes for Indian MSM at an individual level, our findings point to the potential strength of strategies that focus on self-acceptance of one's sexual minority identity to foster better psychosocial and overall health.

    2014-11-01

    Researchers have examined perceived discrimination as a risk factor for depression among sexual minorities; however, the role of religion as a protective factor is under-investigated, especially among sexual minority youth. Drawing on a cross-sectional study investigating campus climate at a large public university in the U.S. midwest, we examined the role of affiliation with a gay-affirming denomination (i.e., endorsing same-sex marriage) as a moderating factor in the discrimination-depression relationship among self-identified sexual minority (n = 393) and heterosexual youth (n = 1,727). Using multivariate linear regression analysis, religious affiliation was found to moderate the discrimination-depression relationship among sexual minorities. Specifically, the results indicated that the harmful effects of discrimination among sexual minority youth affiliated with denominations that endorsed same-sex marriage were significantly less than those among peers who affiliated with denominations opposing same-sex marriage or who identified as secular. In contrast, religious affiliation with gay-affirming denominations did not moderate the discrimination-depression relationship among heterosexual participants. The findings suggest that, although religion and same-sex sexuality are often seen as incompatible topics, it is important when working with sexual minority clients for clinicians to assess religious affiliation, as it could be either a risk or a protective factor, depending on the religious group's stance toward same-sex sexuality. To promote the well-being of sexual minority youth affiliated with denominations opposed to same-sex marriage, the results suggest these faith communities may be encouraged to reconsider their position and/or identify ways to foster youth's resilience to interpersonal discrimination.

    This cross-sectional study assessed sexually transmitted infection (STI) prevalence, socio-demographic characteristics, substance use, sexual behaviors, and sexual network profiles among African American sexual minorities in Jackson, Mississippi. Bivariate chi-square tests and generalized estimating equation (GEE) models explored individual and partner-related factors. Compared to their heterosexual counterparts, male African American sexual minorities reported fewer sex partners (odds ratios [OR] 0.33, 95% confidence intervals [CI] 0.16-0.65) and lower concurrency levels (OR 0.42, 95%CI 0.24-0.72). African American sexual minority women reported greater substance abuse, more sex partners (OR 2.54, 95%CI 1.47-4.38), higher concurrency levels (OR 1.81, 95%CI 1.24-2.64), and more transactional sex (OR 2.52, 95%CI 1.25-5.11).

    While research examining healthcare experiences of sexual minority individuals is growing, thus far research has been limited on lesbian gender identity and its relationship to physical and mental health. This study explores access to and experiences of healthcare with a sample of 516 butch and femme identified lesbian and bisexual women. In comparison to femme-identified women, it was found that butch women had routine gynecological examinations significantly less frequently, perceived poorer treatment in healthcare settings, were more likely to be out within healthcare settings, placed more importance on securing LGBT-positive healthcare practitioners, and had more difficulty finding LGBT-positive medical doctors. No differences were found for mental health. The results suggest that butch women may be more at risk for physical health concerns than femme women, in particular those illnesses that can be prevented or treated with regular gynecological care (e.g., uterine or cervical cancer). Implications of the study include greater awareness among healthcare professionals of sexual minority gender identity in addition to sexual identity, and more support for butch-identified women to access vital healthcare services.

    Purpose Bullying has become a significant public health issue, particularly among youth. This study documents cyberbullying, homophobic bullying and bullying at school or elsewhere and their correlates among both heterosexual and sexual-minority high school students in Quebec (Canada). Method A representative sample of 8,194 students aged 14–20 years was recruited in Quebec (Canada) high schools. We assessed cyberbullying, homophobic bullying and bullying at school or elsewhere in the past 12 months and their association with current self-esteem and psychological distress as well as suicidal ideations. Results Bullying at school or elsewhere was the most common form of bullying (26.1%), followed by cyberbullying (22.9%) and homophobic bullying (3.6%). Overall, girls and sexual-minority youth were more likely to experienced cyberbullying and other form of bullying as well as psychological distress, low self-esteem and suicidal ideations. The three forms of bullying were significantly and independently associated with all mental health outcomes. Conclusions The results underscore the relevance of taking into account gender and sexual orientation variations in efforts to prevent bullying experience and its consequences. PMID:26047959

    Family support and rejection are associated with health outcomes among sexual minority women (SMW). We examined a social ecological development model among young adult SMW, testing whether identity risk factors or outness to family interacted with family rejection to predict community connectedness and collective self-esteem. Lesbian and bisexual women (N = 843; 57% bisexual) between the ages of 18-25 (M = 21.4; SD = 2.1) completed baseline and 12-month online surveys. The sample identified as White (54.2%), multiple racial backgrounds (16.6%), African American (9.6%) and Asian/Asian American (3.1%); 10.2% endorsed a Hispanic/Latina ethnicity. Rejection ranged from 18 to 41% across family relationships. Longitudinal regression indicated that when outness to family increased, SMW in highly rejecting families demonstrated resilience by finding connections and esteem in sexual minority communities to a greater extent than did non-rejected peers. But, when stigma concerns, concealment motivation, and other identity risk factors increased over the year, high family rejection did not impact community connectedness and SMW reported lower collective self-esteem. Racial minority SMW reported lower community connectedness, but not lower collective self-esteem. Families likely buffer or exacerbate societal risks for ill health. Findings highlight the protective role of LGBTQ communities and normative resilience among SMW and their families. PMID:25572956

    The evolution and spread of antibiotic-resistant pathogens has become a major threat to public health. Advanced tools are urgently needed to quickly diagnose antibiotic-resistant infections to initiate appropriate treatment. Here we report the development of a highly sensitive flow cytometric method to probe minority population of antibiotic-resistant bacteria via single cell detection. Monoclonal antibody against TEM-1 β-lactamase and Alexa Fluor 488-conjugated secondary antibody were used to selectively label resistant bacteria green, and nucleic acid dye SYTO 62 was used to stain all the bacteria red. A laboratory-built high sensitivity flow cytometer (HSFCM) was applied to simultaneously detect the side scatter and dual-color fluorescence signals of single bacteria. By using E. coli JM109/pUC19 and E. coli JM109 as the model systems for antibiotic-resistant and antibiotic-susceptible bacteria, respectively, as low as 0.1% of antibiotic-resistant bacteria were accurately quantified. By monitoring the dynamic population change of a bacterial culture with the administration of antibiotics, we confirmed that under the antimicrobial pressure, the original low population of antibiotic-resistant bacteria outcompeted susceptible strains and became the dominant population after 5hours of growth. Detection of antibiotic-resistant infection in clinical urine samples was achieved without cultivation, and the bacterial load of susceptible and resistant strains can be faithfully quantified. Overall, the HSFCM-based quantitative method provides a powerful tool for the fundamental studies of antibiotic resistance and holds the potential to provide rapid and precise guidance in clinical therapies.

    This study explored correlates of condom use within a respondent-driven sample of 190 Spanish-speaking immigrant Latino sexual minorities, including gay and bisexual men, other men who have sex with men (MSM), and transgender person, in North Carolina. Five analytic approaches for modeling data collected using respondent-driven sampling (RDS) were compared. Across most approaches, knowledge of HIV and sexually transmitted infections (STIs) and increased condom use self-efficacy predicted consistent condom use and increased homophobia predicted decreased consistent condom use. The same correlates were not significant in all analyses but were consistent in most. Clustering due to recruitment chains was low, while clustering due to recruiter was substantial. This highlights the importance accounting for clustering when analyzing RDS data. PMID:25646728

However, those studies, like the climate studies through a racial lens, found that lesbian, gay,…

    The purpose of this study is to more completely quantify smoking and intention to quit from a sample of sexual and gender minority (SGM) Black individuals (N = 639) through analysis of data collected at Pride festivals and online. Frequencies described demographic characteristics; chi-square analyses were used to compare tobacco-related variables. Black SGM smokers were more likely to be trying to quit smoking than White SGM smokers. However, Black SGM individuals were less likely than White SGM individuals to become former smokers. The results of this study indicate that smoking behaviors may be heavily influenced by race after accounting for SGM status. PMID:25470333

  18. Sexually-transmitted disease risk in a Micronesian atoll population.

    The potential health threat of AIDS to the native island-based populations in the Pacific is now widely appreciated by those working in the public-health sector throughout the region. Although several countries in the region are yet to identify any cases of AIDS or HIV seropositivity, there is reason to suspect that heterosexual contact may emerge as a predominant mode of spread of HIV infection into native Pacific island populations. Sexual networks and their relationship to potentially 'risky behaviours' are described for a single native Micronesian atoll community on the basis of ethnographic observation and interviewing. This description is combined with the investigation of historic-demographic dimensions of the epidemiology of sexually-transmitted diseases in the same population to draw some conclusions about the opportunities for HIV transmission and acquisition among the sexually-active portions of this community. Although sexually-transmitted diseases have not had an appreciable epidemiological or demographic impact on the population in the past, the sexual networks within the community and beyond provide ample opportunity for the introduction and spread of sexually transmitted diseases, including HIV and its sequel AIDS.

    Drosophila mettleri is found in deserts of North America breeding in soil soaked by the juices of necrotic cacti. Saguaro (Carnegiea gigantea) and cardn (Pachycereus pringlei) are the usual host cacti in Mexico and Arizona, while prickly pear (Opuntia spp.) is used by an isolated population on Santa Catalina Island off the southern California Coast. Populations of D. mettleri show significant local genetic differentiation, especially when geographical isolation is coupled with host shifts. We tested for evidence of sexual isolation among allopatric populations of D. mettleri using a variety of choice and no-choice tests. Populations exhibited significant differences in mating propensity, which translated into significant deviations from random mating. While in some cases these deviations were consistent with sexual isolation, in others, negative assortative mating was observed. No relationship between degree of genetic differentiation and the appearance of sexual isolation was detected. PMID:18561017

    Research has documented significant relationships between sexual and gender minority stress and higher rates of suicidality (i.e. suicidal ideation and attempts) and substance use problems. We examined the potential mediating role of substance use problems on the relationship between sexual and gender minority stress (i.e. victimization based on lesbian, gay, bisexual, or transgender identity [LGBT]) and suicidality. A nonprobability sample of LGBT patients from a community health center (N = 1457) ranged in age from 19-70 years. Participants reported history of lifetime suicidal ideation and attempts, substance use problems, as well as experiences of LGBT-based verbal and physical attacks. Substance use problems were a significant partial mediator between LGBT-based victimization and suicidal ideation and between LGBT-based victimization and suicide attempts for sexual and gender minorities. Nuanced gender differences revealed that substance use problems did not significantly mediate the relationship between victimization and suicide attempts for sexual minority men. Substance use problems may be one insidious pathway that partially mediates the risk effects of sexual and gender minority stress on suicidality. Substances might be a temporary and deleterious coping resource in response to LGBT-based victimization, which have serious effects on suicidal ideation and behaviors. PMID:23535038

    Stigma, discrimination and violence contribute to health disparities among sexual minorities. Lesbian, bisexual and queer (LBQ) women experience sexual violence at similar or higher rates than heterosexual women. Most research with LBQ women, however, has focused on measuring prevalence of sexual violence rather than its association with health outcomes, individual, social and structural factors. We conducted a cross-sectional online survey with LBQ women in Toronto, Canada. Multivariate logistic regression analyses were conducted to assess correlates of lifetime sexual assault (LSA). Almost half (42%) of participants (n = 415) reported experiences of LSA. Participants identifying as queer were more likely to have experienced LSA than those identifying as lesbian. When controlling for socio-demographic characteristics, experiencing LSA was associated with higher rates of depression, sexually transmitted infections (STIs), receiving an STI test, belief that healthcare providers were not comfortable with their LBQ sexual orientation, and sexual stigma (overall, perceived and enacted). A history of sexual violence was associated with lower: self-rated health, overall social support, family social support and self-esteem. This research highlights the salience of a social ecological framework to inform interventions for health promotion among LBQ women and to challenge sexual stigma and sexual violence. PMID:24412812

    Abstract Immigrant sexual and gender minority Latinos constitute a vulnerable subgroup about which little is known. We examined HIV testing among 190 such Latinos recruited via respondent-driven sampling in North Carolina, a state with little historical Latino presence but recent, rapid growth of this population. Sixty-eight percent reported an HIV test in the past year, and nearly half reported multiple HIV tests. Concern for their health was the most frequent reason for seeking an HIV test. Reasons not to get tested included fear of a positive test, previous HIV tests, worry that test results might be reported to the government, and concerns that others might treat the person differently if found to be HIV positive. In a multiple variable model, correlates of HIV testing included age, educational attainment, HIV stigma, comfort with sexual orientation, and previous STD diagnoses. Among participants reporting anal sex, consistent condom use was associated with HIV testing, suggesting that protective behaviors may co-occur. These findings may inform the development of more efficacious interventions to increase HIV testing among this subgroup. PMID:24138487

    Using the transition matrix of inbreeding and coancestry coefficients, the inbreeding (N(eI)), variance (N(eV)), and asymptotic (N(e lambda)) effective sizes of mixed sexual and asexual populations are formulated in terms of asexuality rate (delta), variance of asexual (C) and sexual (K) reproductive contributions of individuals, correlation between asexual and sexual contributions (rho(ck)), selfing rate (beta), and census population size (N). The trajectory of N(eI) toward N(e lambda) changes crucially depending on delta, N, and beta, whereas that of N(eV) is rather consistent. With increasing asexuality, N(e lambda) either increases or decreases depending on C, K, and rho(ck). The parameter space in which a partially asexual population has a larger N(e lambda) than a fully sexual population is delineated. This structure is destroyed when N(1 - delta) < 1 or delta > 1 - 1/N. With such a high asexuality, tremendously many generations are required for the asymptotic size N(e lambda) to be established, and N(e lambda) is extremely large with any value of C, K, and rho(ck) because the population is dominated eventually by individuals of the same genotype and the allelic diversity within the individuals decays quite slowly. In reality, the asymptotic state would occur only occasionally, and instantaneous rather than asymptotic effective sizes should be practical when predicting evolutionary dynamics of highly asexual populations.

    Lesbian, gay, bisexual, and queer/questioning youth health disparities are well documented; however, study limitations restrict our understanding of how the temporal interplay among domains of sexuality (attraction, behavior, and identity) situate individuals to be more or less at risk for poor mental health and alcohol use across the transition to adulthood. Four waves of data from the National Longitudinal Study of Adolescent to Adult Health (n=12,679; 51.29% female) were used with repeated measures latent class analysis to estimate sexual trajectory groups designated by prospective reports of romantic attraction, sexual/romantic behavior, and sexual identity from adolescence to adulthood. Five unique trajectories emerged: two heterosexual groups (heterosexual early daters [58.37%] and heterosexual later daters [29.83%]) and three sexual minority groups (heteroflexible [6.44%], later bisexually identified [3.32%], and LG[B] identified [2.03%]). These sexual trajectories differentiate risk for depressive symptomology, suicidal thoughts and behaviors, and alcohol use during adolescence and early adulthood. Groups where individuals first reported same-sex attraction and sexual minority identities in adulthood (heteroflexible and later bisexually identified) had similar levels of depression, suicidality, and greater substance use than those who largely reported same-sex attraction and behavior during adolescence (the LG[B] identified group). These later recognition groups showed greater risk for poor outcomes in waves where they also first reported these changes in attraction, behaviors, and identities. The emergence of three sexual minority groups reveal within-group differences in sexuality and sexual trajectories and how these experiences relate to risk and timing of risk across the transition to adulthood.

    The main aim of this study was to investigate the effect of childhood sexual abuse on medically not well explained or functional somatic symptoms (FSSs) in adolescents. We hypothesized that sexual abuse predicts higher levels of FSSs and that anxiety and depression contribute to this relationship. In addition, we hypothesized that more severe abuse is associated with higher levels of FSSs and that sexual abuse is related to gastrointestinal FSSs in particular. This study was part of the Tracking Adolescents' Individual Lives Survey (TRAILS): a general population cohort which started in 2001 (N=2,230; 50.8% girls, mean age 11.1 years). The current study uses data of 1,680 participants over four assessment waves (75% of baseline, mean duration of follow-up: 8 years). FSSs were measured by the Somatic Complaints subscale of the Youth Self-Report at all waves. Sexual abuse before the age of sixteen was assessed retrospectively with a questionnaire at T4. To test the hypotheses linear mixed models were used adjusted for age, sex, socioeconomic status, anxiety and depression. Sexual abuse predicted higher levels of FSSs after adjustment for age sex and socioeconomic status (B=.06) and after additional adjustment for anxiety and depression (B=.03). While sexual abuse involving physical contact significantly predicted the level of FSSs (assault; B=.08, rape; B=.05), non-contact sexual abuse was not significantly associated with FSSs (B=.04). Sexual abuse was not a stronger predictor of gastrointestinal FSSs (B=.06) than of all FSSs. Further research is needed to clarify possible mechanisms underlying relationship between sexual abuse and FSSs. PMID:26142915

    Previous studies documenting sexual minority women's disproportionate risk for a range of medical, mental health, and substance use disorders have not provided a predictive framework for understanding their interrelations and outcomes. The present study aimed to address this gap by testing the syndemic effect of co-occurring psychosocial problems on 7-year health care costs and utilization among sexual minority women. The sample was comprised of sexual minority women (N?=?341) who were seen at an urban LGBT-affirmative community health center. Medical and mental health care utilization and cost data were extracted from electronic medical records. Demographically adjusted regression models revealed that co-occurring psychosocial problems (i.e., childhood sexual abuse, partner violence, substance use, and mental health distress [history of suicide attempt]) were all strongly interrelated. The presence of these indicators had a syndemic (additive) effect on medical costs and utilization and mental health utilization over 7-year follow-up, but no effect on 7-year mental health costs. These results suggest that the presence and additive effect of these syndemic conditions may, in part, explain increased medical costs and utilization (and higher medical morbidity) among sexual minority women.

    Background Few studies have examined the impact of minority stress theory upon sexual risk behavior among gay and bisexual men using club drugs. Similar studies have focused on ethnic minorities and women, however gay and bisexual men demonstrate greater likelihood for risk behaviors leading to HIV/AIDS. Objective This study examined sexual risk behavior from the perspective of minority stress theory upon substance using gay and bisexual men and their partners. Methods Multivariable logistic regression analysis examined minority stress associations with participant sexual risk behaviors, drug use and partner type, controlling for demographics. Results 396 gay and 54 bisexual respondents, ages 18-67 reported at least one time drug use while engaging in sexual risk behavior. In the adjusted model, expectations of rejection associated with lower odds of sexual risk behavior, while older age approached significance. Conclusions Theoretical origins for examining risk behavior among gay and bisexual men may underscore risk and protective factors, while ultimately holding implications for prevention and treatment interventions.

    Objective Adult posttraumatic stress symptoms (PSS) and a biomarker index of current health risk in childhood sexual abuse (CSA) survivors was investigated in relation to CSA severity, disclosure and other peri-and post-trauma factors. Methods A community sample of 94 African American and Latina women CSA survivors was assessed. Results Severe CSA predicted PSS overall, avoidance/numbing symptoms and greater biomarker risk, and was not mediated by post-trauma variables. Moderate CSA severity was mediated by post-trauma disclosure, predicted re-experiencing symptoms but was unrelated to biomarker risk. No overall ethnic differences were found. Conclusions Results suggest targets for interventions to improve the well-being of minority women CSA survivors. PMID:20373204

    Sexual minority youth (SMY) face multiple risks in their daily lives that may influence their need for supportive care. Health and social service providers have unique opportunities to provide culturally competent services to these youth. This article describes a community-based educational intervention created to increase providers' knowledge, skills, and intention to support SMY. Based on the Information-Motivation-Behavioral Skills model, this pilot study found that for a diverse sample of multidisciplinary professionals (n = 2,850), the odds of behavioral intention (BI) to support SMY were significantly higher when trainings were relevant to the professionals' experience (OR = 1.3), were sensitive (OR = 1.3), developed skills (OR = 1.1), and incorporated policy (OR = 1.2). Implications for the delivery of community-based trainings are provided. PMID:26305479

    Limited research exists about the unique experiences and possible marginalization of children with sexual minority parents. From a larger longitudinal project of diverse adoptive families, we examined cross-sectional data using mixed methods from interviews with 49 adopted children (M age  = 8 years; 47 % female) in 27 two-father and 22 two-mother families. Using thematic analysis, we coded themes of awareness of difference, microaggressions, and resilience (i.e., coping and positive family conceptualizations). Children experienced "feeling different" and microaggressions from peers, but generally at a low to medium intensity and with neutral (not negative) emotion. More instances of resilience and positive family conceptualizations were reported than microaggressions or feelings of difference, suggesting that children develop positive perceptions of their family and navigate experiences of difference with resilience. Filling important gaps in the literature, we discuss implications of our results for practice and policy. PMID:26374241

    Using computer simulations of a bit-string model for age-structured populations, we found that sexual selection of older males is advantageous, from an evolutionary point of view. These results are in opposition to a recent proposal of females choosing younger males. Our simulations are based on findings from recent studies of polygynous bird species. Since secondary sex characters are found mostly in males, we could make use of asexual populations that can be implemented in a fast and efficient way.

    The use of websites and GPS-based mobile applications ("apps") designed for social and sexual networking has been associated with increased HIV risk; however, little is known about Latino sexual minorities' and transgender persons' use of these websites and apps and the risk profiles of those who use them compared with those who do not. Data from 167 participants who completed the baseline survey of a community-level HIV prevention intervention, which harnesses the social networks of Latino sexual minorities and transgender persons, were analyzed. One quarter of participants (28.74%, n = 48) reported using websites or apps designed for social and sexual networking, and 119 (71.26%) reported not using websites or apps designed for social and sexual networking. Those who used websites or apps were younger and reported more male sex partners, a sexually transmitted disease diagnosis, and illicit drug use other than marijuana. HIV prevention interventions for those who use websites or apps should consider addressing these risks for HIV. PMID:26272786

    Given the size of the patient population of the Veterans Health Administration (VHA), it is likely the largest single provider of health care for sexual and gender minority (SGM) individuals in the United States, including lesbian, gay, bisexual, and transgender persons. However, current VHA demographic data-collection strategies limit the understanding of how many SGM veterans there are, thereby making a population-based understanding of the health needs of SGM veterans receiving care in VHA difficult. In this article, we summarize the emergent research findings about SGM veterans and the first initiatives that have been implemented by VHA to promote quality care. Though the research on SGM veterans is in its infancy, it suggests that SGM veterans share some of the health risks noted in veterans generally and also risks associated with SGM status. Some promising resiliency factors have also been identified. These findings have implications for both VHA and non-VHA systems in the treatment of SGM veterans. However, more research on the unique needs of SGM veterans is needed to fully understand their health risks and resiliencies in addition to health-care utilization patterns. PMID:26789509

    Purpose Research suggests that discrimination contributes to increased substance use among sexual minorities. Subtle discrimination and witnessing mistreatment, however, have received little attention. Using minority stress theory as a conceptual framework the authors examined the intersection of sexual orientation, experiencing and witnessing incivility and hostility, and students’ alcohol and drug use. The authors hypothesized that experiencing/witnessing incivility/hostility would mediate the relationship between sexual minority status and drinking and drug use, as well as problematic use of these substances. Methods Data were taken from a campus climate survey (n = 2497; age mean [M] = 23.19 years; 61% female; 17% sexual minorities). Controlling for demographics, logistic regressions depicted specifications for each path of the mediation analysis and bootstrapping was used to assess the significance of each sexual minority-mistreatment-drinking/drug use path. Results Experiencing incivility mediated the relationship between sexual minority status and problematic drinking. Sexual minority college students were more likely to personally experience incivility (adjusted odds ratio [AOR] = 1.87; 95% confidence interval [CI] = 1.51–2.33), which was associated with greater odds of problematic drinking (AOR = 1.64; 95% CI = 1.35–2.00). The mediation path was significant at P < 0.001. Further, witnessing hostility mediated the relationship between sexual minority status and problematic drinking. Sexual minority college students were more likely to witness hostility (AOR = 1.87, 95% CI = 1.48–2.36), which was associated with greater odds of problematic drinking (AOR = 1.53; 95% CI = 1.24–1.90). The mediation path was significant at P < 0.01. Conclusion The results provide further evidence for minority stress theory and suggest that clinical alcohol use interventions with sexual minorities need to assess personal incivilities and witnessing interpersonal mistreatment, especially hostility. Campus climate interventions that address subtle discrimination as well as harassment and violence may help reduce problematic drinking. PMID:24474863

    Research suggests that the timing and sequence of sexual identity development milestones impacts myriad health and mental health outcomes for sexual minority youth. Because these milestone events are typically assessed retrospectively, traditional data collection approaches are limited by recall bias and lack of precision in the recording of milestone events, which may conceal the distinctions between events and distort the recording of youths' developmental trajectories. The purpose of this exploratory study was to compare responses to questions about psychosexual milestones elicited by a Life History Calendar and a self-administered survey. Results indicated discrepancies in the reported occurrence and timing of milestone events between the survey and Life History Calendar. Differences in the timing of specific milestone events ranged from two months to 15 years. Implications of these discordant findings for sexual minority youth are discussed. PMID:22957108

Data suggest that people in this group face a significant and poorly understood set of additional health risks and bear a higher burden of some diseases compared to the general population. A large amount of data is available on HIV/AIDS, but far less on other health problems. In this review we aimed to synthesize the knowledge on the burden of communicable and non-communicable diseases, mental health conditions and violence experienced by SGM, based on available systematic reviews. We conducted a global review of systematic reviews, including searching the Cochrane and the Campbell Collaboration libraries, as well as PubMed, using a range of search terms describing the populations of interest, without time or language restrictions. Google Scholar was also scanned for unpublished literature, and references of all selected reviews were checked to identify further relevant articles. We found 30 systematic reviews, all originally written in English. Nine reviews provided data on HIV, 12 on other sexually transmitted infections (STIs), 4 on cancer, 4 on violence and 3 on mental health and substance use. A quantitative meta-analysis was not possible. The findings are presented in a narrative format. Our review primarily showed that there is a high burden of disease for certain subpopulations of SGM in HIV, STIs, STI-related cancers and mental health conditions, and that they also face high rates of violence. Secondly, our review revealed many knowledge gaps. Those gaps partly stem from a lack of original research, but there is an equally urgent need to conduct systematic and literature reviews to assess what we already know on the disease burden in SGM. Additional reviews are needed on the non-biological factors that could contribute to the higher disease burden. In addition, to provide universal access to health-care for all, more information is needed on the barriers that SGM face in accessing health services, including the attitudes of health-care providers. Understanding these barriers and the additional health risks they impose is crucial to improving the health status of SGM. PMID:26800682

    The HOLA intervention was a lay health advisor intervention designed to reduce the disproportionate HIV burden borne by Latino sexual and gender identity minorities (gay, bisexual, and other men who have sex with men, and transgender persons) living in the United States. Process evaluation data were collected for over a year of intervention implementation from 11 trained Latino male and transgender lay health advisors (Navegantes) to document the activities each Navegante conducted to promote condom use and HIV testing among his or her eight social network members enrolled in the study. Over 13 months, the Navegantes reported conducting 1,820 activities. The most common activity was condom distribution. Navegantes had extensive reach beyond their enrolled social network members, and they engaged in health promotion activities beyond social network members enrolled in the study. There were significant differences between the types of activities conducted by Navegantes depending on who was present. Results suggest that lay health advisor interventions reach large number of at-risk community members and may benefit populations disproportionately affected by HIV. PMID:25416309

    The aim of the study was to determine the differences in sexual behaviour and condom use as a protection against sexually transmitted infections (STI) between the first-year and the last-year students. Data were collected by filling anonymous and consented questionnaire in June of 2011 at University of Josip Juraj Strossmayer in Osijek, Croatia. Out of 857 students in the planned sample, 462 (53.9%) filled out the questionnaire, and 353/462 (76.4%) were sexually active. Data from sexually active students were processed and statistically significant results between first-year and the last-year students were presented. Studied sample consisted of 192/353 (54.4%) first-year students and 161/353 (45.6%) last-year students. Average age of sexual initiation for the first-year students was 17.28 +/- 1.29 years, a for the last-year students 18.45 +/- 2.14 years, and the difference is significant (Man-Whitney test = 10335.00, p < 0.01). First-year students have lower number of sexual partners (chi2 = 28.005, p < 0.01), during relationship they had lower number of intercourses with the third person (2 = 17.947, p < 0.01), and feel that lower number of their friends were already sexually active at the time of their own sexual initiation (chi2 = 18.350, p < 0.01). First-year students more often inform their partners about existing or previous STI (chi2 = 14.476, p < 0.01) and curiosity significantly influenced their decision regarding sexual initiation (chi2 = 8.689, p < 0.05). First-year students more often used condom at their first sexual intercourse (chi2 = 7.275, p < 0.01), and more rarely used withdrawal (chi2 = 6.380, p < 0.05). At their last sexual intercourse, first-year students more often used any kind of protection (chi2 = 3.853, p < 0.05),more often used condom (chi2 = 11.110, p < 0.01) and withdrawal (chi2 = 5.156, p < 0.05), and more rarely used contraceptive pills (chi2 = 4.405, p < 0.05). First-year students more often use condom in a permanent relationship (chi2 = 13.384, p < 0.05), and also plan to use it during following intercourse in the permanent relationship (chi2 = 17.575, p < 0.01). Growing condom use and decreasing risky sexual behaviour among students, as well as other adolescents and young adults needs to be maintained. Youth should learn before sexual initiation that only correct condom use at every sexual intercourse protects them against STI and human immunodeficiency virus (HIV). Sexual education and STI/HIV prevention programmes, positive role of media (television) and civil organisations that communicate with the youth can help that. Such changes among adolescents and young adults should have to be seen in student population as well. PMID:24851594

    Males from different populations of the same species often differ in their sexually selected traits. Variation in sexually selected traits can be attributed to sexual selection if phenotypic divergence matches the direction of sexual selection gradients among populations. However, phenotypic divergence of sexually selected traits may also be influenced by other factors, such as natural selection and genetic constraints. Here, we document differences in male sexual traits among six introduced Australian populations of guppies and untangle the forces driving divergence in these sexually selected traits. Using an experimental approach, we found that male size, area of orange coloration, number of sperm per ejaculate and linear sexual selection gradients for male traits differed among populations. Within populations, a large mismatch between the direction of selection and male traits suggests that constraints may be important in preventing male traits from evolving in the direction of selection. Among populations, however, variation in sexual selection explained more than half of the differences in trait variation, suggesting that, despite within-population constraints, sexual selection has contributed to population divergence of male traits. Differences in sexual traits were also associated with predation risk and neutral genetic distance. Our study highlights the importance of sexual selection in trait divergence in introduced populations, despite the presence of constraining factors such as predation risk and evolutionary history.

    This study examined posttraumatic stress disorder (PTSD) and related symptoms among sexual minority (SM) and heterosexual women and the influence of social support on the relationship between SM status and symptoms. We hypothesized that SM women would endorse higher symptoms of PTSD and related difficulties and that social support would moderate the relationship between SM status and symptoms. The sample, women seeking treatment for PTSD related to interpersonal violence (n = 477; mean age = 36.07 years; 22.9% SM) completed clinician-administered measures of PTSD and self-report measures of trauma-related difficulties and social support. The rate of PTSD diagnosis was higher for SM women. Social support and SM status were significantly associated with suicidality, self-perceptions, depression, somatic complaints, and functional impairment. The interaction between social support and SM status was significant for both functional impairment (? = -.26) and somatic complaints (? = -.39). High social support had an equal, positive effect among SM and nonminority women, whereas low social support had a greater negative impact among SM women. Results suggested the particular salience of social support on functioning and symptom severity among SM women and the potential importance of including interventions addressing social support into PTSD treatments for SM women.

    With few exceptions, it has been found that gay men earn less and lesbians earn more than their heterosexual counterparts. Most of the current literature has used single cross-sectional datasets to test possible sources of these wage differentials. This study adds to this literature by presenting a theoretical framework, grounded in gender theory, to explore: (a) whether sexual minority wage gaps have attenuated over the last decade, (b) whether wage gaps vary by age group, and (c) if wage gaps vary with duration in the labor market. Using Canadian census and survey data, this study finds no evidence that wage gaps have attenuated for gay men and only small reductions for lesbians and heterosexual women, relative to heterosexual men. Wage gaps are larger for younger gay men than for older gay men, which may suggest a "coming out penalty". The lesbian wage premium, vis--vis heterosexual women, does not appear at initial labor market entry; rather it develops with duration in the labour market. PMID:26463538

    Estimates of the extent of childhood sexual abuse (CSA) within in the Roman Catholic Church (RCC) in the general population are difficult to find. The independent Commission of Inquiry into sexual abuse of minors in the RCC in the Netherlands collected population-based data to estimate its prevalence. A large random online population sample was surveyed using a two-phase stratified sampling procedure. In Phase 1, 34,267 subjects aged 40 years and older were screened for childhood exposure to sexual abuse by non-family members, a history of institutionalization and a Roman Catholic upbringing. In Phase 2, a stratified subset of 2,462 subjects was assessed to obtain more detailed target information about sexual abuse reports within the RCC. We employed multiple imputation for the estimation of RCC CSA in the original Phase 1 sample. The prevalence of non-familial CSA in general (14.0%) was higher among women (17.2%) than among men (10.6%). The prevalence of CSA within the Dutch RCC (1.7%) was higher among men (2.7%) than among women (0.7%). As expected, older subjects reported more often CSA in the RCC than their younger counterparts. Respondents who stayed for some time in RCC run institutions for education or child protection had a higher risk to report sexual abuse. Although sexual abuse of minors by representatives of the RCC was a structural problem during a period that the Church was highly influential in the Netherlands, the estimated prevalence of the phenomenon is only a fraction of the prevalence rate of non-familial CSA.

    This thematically analyzed study seeks to explore the career decision perceptions of sexual minority college students at an urban historically black college/university (HBCU). This qualitative focus group study delved into how sexual minorities feel their visible variables of race, gender expression, and degree of disclosure influence their career thought process. Theories relative to the study included Krumboltz's social learning theory of career decision-making, gender role theory, racial socialization, Cass's homosexual identity model, and impression management. Though participants initially proclaimed they did not allow their sexual minority identity to affect their career decisions, their overall responses indicated otherwise. PMID:24885738

  20. Some characteristics and the transition of the population reproduction patterns of China's national minorities.

    PubMed

    Zhang, T

    1983-01-01

    The population reproduction patterns of China's minority groups differ to some extent from those of China as a whole. The population of some of the national minorities, such as the Mongolian, tibetan, and Hezhen nationalities, was actually decreasing before liberation. Cited as causal factors are the oppressive policies of past dynasties, lack of medical care in minority areas, and, in some instances, the religious imposition of strict celibacy on significant numbers of the male populaton. After libertation, reproductive patterns were characterized by a high birth rate and low mortality, resulting in a high growth rate. For example, in 1939-408 the birth rate among the Mongolian nationality in Inner Mongolia was 21.7, and the death rate was 28.3, resulting in a negative growth rate. In the period 1952-3, the birth rate rose to 41.5 while the death rate fell to 17.9 resulting in a growth rate of 23.6. This rapid transition is attributed to State policies of accelerated economic and cultural development in the minority areas, and the development of medical facilities. At present, a 3rd population pattern, characterized by a low birth rate, low mortality, and consequent low growth rate, is being seen among the national minorities. This is attributed to the leadership exhibited by minority cadres in family planning work. While advocating family planning, the State adopted a more flexible policy towards the minorities. A government directive stipulates that the specific rules can be drawn up according to the actual conditions by the nationality autonomous local authorities and the related provinces and autonomous regions. Family planning work has been achieved through the mobilization of the minority populations by the cadres, and by mass education on population theory and the relation between religious beliefs, marriage, and customs and family planning. Freedom of the minority people to preserve or reform their religious belief and customs has been absoluetely respected. PMID:12313407

  1. Sexual assault while too intoxicated to resist: a general population study of Norwegian teenage girls

    2014-01-01

    Background Underage drinking is widespread, but studies on alcohol-related sexual victimization among teenage girls are almost non-existent. Research on individual correlates and risk factors of sexual victimization more generally is also meager. This study focuses on sexual assault while incapacitated due to drunkenness among 1518 year-old girls and examines how age, drinking behavior, impulsivity and involvement in norm-violating activities are associated with such victimization experiences. Methods Data stemmed from a school survey (response rate: 85%) in 16 Norwegian municipalities. Almost all analyses were restricted to girls who had been intoxicated in the past year (n?=?2701). In addition to bivariate associations, adjusted odds ratios and relative risks of incapacitated sexual assault (ISA) were estimated. Further, population-attributable fractions were calculated to explore how the prevalence of ISA victimization was likely to be affected if effective preventive measures were targeted solely at high-risk groups. Results The majority of the girls (71%) had been intoxicated in the past year, of which 7% had experienced ISA victimization in the same period. The proportion of victims decreased by age within the group that had been intoxicated, reflecting that the youngest girls were more likely to get severely drunk. Impulsivity and involvement in norm-violating behaviors were identified as potential risk factors, but the population-attributable fractions indicated that the groups with the highest risk of ISA victimization accounted for only a minority of all the cases of such victimization. Conclusion Sexual assault against teenage girls who are too drunk to resist seems to be prevalent in Norway notably among the youngest girls who engage in heavy episodic drinking. This study also suggests that one should reconsider the notion that no individual attributes are related to females sexual assault victimization. It also indicates that a high risk approach to prevention, targeting groups with a high level of impulsivity or behavioral problems, may have limited effect on the prevalence of ISA victimization. Thus, from a public health perspective, it may be advisable to give priority to universal preventive measures to curb young girls risk of being sexually assaulted in a state of alcohol-induced incapacitation.

    Whether and how human populations exposed to the agricultural revolution are still affected by Darwinian selection remains controversial among social scientists, biologists, and the general public. Although methods of studying selection in natural populations are well established, our understanding of selection in humans has been limited by the availability of suitable datasets. Here, we present a study comparing the maximum strengths of natural and sexual selection in humans that includes the effects of sex and wealth on different episodes of selection. Our dataset was compiled from church records of preindustrial Finnish populations characterized by socially imposed monogamy, and it contains a complete distribution of survival, mating, and reproductive success for 5,923 individuals born 1760-1849. Individual differences in early survival and fertility (natural selection) were responsible for most variation in fitness, even among wealthier individuals. Variance in mating success explained most of the higher variance in reproductive success in males compared with females, but mating success also influenced reproductive success in females, allowing for sexual selection to operate in both sexes. The detected opportunity for selection is in line with measurements for other species but higher than most previous reports for human samples. This disparity results from biological, demographic, economic, and social differences across populations as well as from failures by most previous studies to account for variation in fitness introduced by nonreproductive individuals. Our results emphasize that the demographic, cultural, and technological changes of the last 10,000 y did not preclude the potential for natural and sexual selection in our species. PMID:22547810

    Objectives. We used nationally representative data to investigate health disparities associated with sexual minority status among adults in the United States. Methods. We analyzed data from 11 114 adults who participated in the 2001 to 2010 waves of the National Health and Nutrition Examination Survey. Using multiple logistic regressions, we examined the prevalence of HIV, sexually transmitted infections, mental health problems, cigarette smoking, and alcohol and illicit drug use in sexual minorities and heterosexual adults. Results. After adjusting for sociodemographic characteristics, sexual minority men had greater odds of mental health problems, testing positive for HIV and herpes simplex virus type 2 and self-reported gonorrhea and chlamydia. Sexual minority women had greater odds of mental health problems, testing positive for hepatitis C, smoking, heavy drinking, and illicit drug use. Conclusions. Numerous health disparities continue to face sexual minority men and women in the United States. Notably, health disparities persisted beyond the role of sociodemographic factors, including access to insurance and primary care, suggesting that further research is warranted to identify the determinants of health inequity for sexual minorities.

    Elucidating the genetic basis of complex traits and diseases in non-European populations is particularly challenging because US minority populations have been under-represented in genetic association studies. We developed an empirical Bayes approach named XPEB (cross-population empirical Bayes), designed to improve the power for mapping complex-trait-associated loci in a minority population by exploiting information from genome-wide association studies (GWASs) from another ethnic population. Taking as input summary statistics from two GWASs-a target GWAS from an ethnic minority population of primary interest and an auxiliary base GWAS (such as a larger GWAS in Europeans)-our XPEB approach reprioritizes SNPs in the target population to compute local false-discovery rates. We demonstrated, through simulations, that whenever the base GWAS harbors relevant information, XPEB gains efficiency. Moreover, XPEB has the ability to discard irrelevant auxiliary information, providing a safeguard against inflated false-discovery rates due to genetic heterogeneity between populations. Applied to a blood-lipids study in African Americans, XPEB more than quadrupled the discoveries from the conventional approach, which used a target GWAS alone, bringing the number of significant loci from 14 to 65. Thus, XPEB offers a flexible framework for mapping complex traits in minority populations. PMID:25892113

    On the basis of integrating objectification theory research with research on body image and eating problems among sexual minority men, the present study examined relations among sociocultural and psychological correlates of eating disorder symptoms with a sample of 231 sexual minority men. Results of a path analysis supported tenets of objectification theory with the sample. Specifically, findings were consistent with relations posited in objectification theory among sexual objectification experiences, internalization of cultural standards of attractiveness, body surveillance, body shame, and eating disorder symptoms. Within this set of positive relations, internalization of cultural standards of attractiveness partially mediated the link of sexual objectification experiences with body surveillance; body surveillance partially mediated the relation of internalization with body shame; and body shame partially mediated the relation of body surveillance with eating disorder symptoms. In addition to these relations, internalized homophobia was related to greater eating disorder symptoms through body shame, and recalled childhood harassment for gender nonconformity was linked with eating disorder symptoms through a positive series of relations involving internalization of cultural standards of attractiveness, body surveillance, and body shame.

  11. Testing a Model of Minority Identity Achievement, Identity Affirmation and Psychological Well-Being among Ethnic Minority and Sexual Minority Individuals

    2011-01-01

    How is social identity related to psychological well-being among minority individuals? Drawing on developmental models of identity formation (e.g., Erikson, 1968) and on Social Identity Theory (Tajfel & Turner, 1979), we tested a conceptual model examining links between two key aspects of social identity and psychological well-being. We proposed that the association between identity achievement (exploring and understanding the meaning of ones identity) and psychological well-being is mediated by identity affirmation (developing positive feelings and a sense of belonging to ones social group). Across three studies, including ethnic minority high school students (Study 1), ethnic minority college students (Study 2) and lesbian and gay male adults (Study 3), we found strong support for the model. Results suggest that the process of exploring and understanding ones minority identity can serve as an important basis for developing positive feelings toward and an enhanced sense of attachment to the group which can in turn confer psychological benefits for minority individuals. Implications and directions for future research are discussed. PMID:21341900

Participants were 5,388 males from the U.S. national Growing Up Today Study. In 2001, 2003, and 2005 (spanning ages 15-20 years), participants reported sexual orientation, past-year desire for toned/defined muscles and concerns with weight and shape, and past-year binge eating, restrictive dieting, purging (vomiting or laxative use), and use of products to increase muscularity (e.g., creatine, steroids). Latent class analyses identified 2 patterns at ages 15-16 years and 3 patterns at 17-18 and 19-20 years: healthy (all ages; low body image concerns and weight- and shape-related behaviors; 54-74% of observations), muscle-concerned (ages 17-18 and 19-20; relatively high muscularity concern and product use; 18-21% of observations), and lean-concerned (all ages; relatively high weight and shape concern, dieting, and binge eating; 19-28% of observations). Latent transition analyses revealed that sexual minority males (i.e., mostly heterosexual, gay, and bisexual) were more likely than completely heterosexual males to be lean-concerned at ages 17-18 and 19-20 years and to transition to the lean-concerned class from the healthy class. There were no sexual orientation differences in odds of being muscle-concerned. Both heterosexual and sexual minority males are at risk for presenting body image concerns and weight- and shape-related behaviors that may have deleterious health consequences. Results suggest the need for screening for concerns and behaviors related to leanness and muscularity in early adolescence among all males, regardless of sexual orientation. PMID:26098578

Latent class analyses identified two patterns at ages 15–16 years and three patterns at 17–18 and 19–20 years: Healthy (all ages; low body image concerns and weight-and shape-related behaviors; 54%–74% of observations), Muscle-Concerned (ages 17–18 and 19– 20; relatively high muscularity concern and product use; 18%–21% of observations), and Lean-Concerned (all ages; relatively high weight and shape concern, dieting, and binge eating; 19%– 28% of observations). Latent transition analyses revealed that sexual minority males (i.e., mostly heterosexual, gay, and bisexual) were more likely than completely heterosexual males to be Lean-Concerned at ages 17–18 and 19–20 years and to transition to the Lean-Concerned class from the Healthy class.

    We have investigated the rate of substitution of advantageous mutations in populations of haploid organisms where the rate of recombination can be controlled. We have verified that in all the situations recombination speeds up adaptation through recombination of beneficial mutations from distinct lineages in a single individual, and so reducing the intensity of clonal interference. The advantage of sex for adaptation is even stronger when deleterious mutations occur since now recombination can also restore genetic background free of deleterious mutations. However, our simulation results demonstrate that evidence of clonal interference, as increased mean selective effect of fixed mutations and reduced likelihood of fixation of small-effect mutations, are also present in sexual populations. What we see is that this evidence is delayed when compared to asexual populations.

    The assumption that early sexual debut leads to adverse outcomes has been used as justification for sexual health interventions and policies aimed at delaying sexual initiation, yet research in the area has been limited. This review identified and synthesized published literature on the association between early first sexual intercourse and later sexual/reproductive outcomes. Literature searches were conducted in Medline, Embase, PsycINFO, and Current Contents. In all, 65 citations met the selection criteria (industrialized, population-based studies). By far the most common sexual behavior to have been investigated has been sexual partners. Studies consistently reported early first intercourse to be associated with more recent, lifetime, and concurrent sexual partners. Early initiators were also more likely to participate in a wider range of sexual practices and report increased sexual satisfaction (among men). Furthermore, early first intercourse, in some studies, was shown to increase the risk of teen pregnancies, teen births, and having an abortion, while findings on STIs and contraceptive use have been mixed. These findings, however, must be interpreted with caution due to methodological problems and limitations present in the research, including a lack of consensus on what constitutes early sexual intercourse and inconsistencies and problems with analyses.

    Health care spending is often addressed in discussions of budgeting and deficits in the United States. It is important to many Americans that funds allocated for health care spending be allocated and spent in the most efficient and effective manner, leading to improved health outcomes, particularly for underserved populations. Many studies address health care spending, but few address the issue of spending as it relates to societal well-being, or certain health outcomes that adversely impact communities. This study seeks to expand the available literature by analyzing data from national sources at the state level. PMID:26333605

  18. Adolescent sexuality in Asia: new focus for population policy.

    As the age at marriage continues to rise in East and Southeast Asia, the fertility behavior of unmarried teenagers is receiving more attention from population policymakers. In addition to fertility reduction through family planning, Asian societies today consider population planning strategies in relation to national needs and social goals, including such matters as the population's growth rate, age structure, educational quality and skills. The number of single youth in Asia is growing much more rapidly than the total youth population. By the year 2010, for example, India is projected to have nearly 70 million single teenagers, aged 15-19, 188% more than in 1980. In many developing countries today, such as the Philippines and Korea, the rising age at marriage has combined with rapid urbanization, improved status for women, and more educational opportunity to alter both the behavioral norms of young people and the traditional means of social control over youth. Studies of contemporary adolescent sexuality have been conducted in 4 Asian countries. In the Philippines an overt independent youth homosexual culture was found to exist in urban and to some extent rural areas. In Thailand research revealed little conservative resistance to family planning or to contraceptives for young unmarried people. Surveys in Taiwan indicate that behavior related to dating and choice of spouse has become more liberal, and a survey in Hong Kong revealed a higher level of premarital sex and use of prostitutes among Chinese men than expected. Population policy perspectives that need to be considered in these changing times include: 1) issues of access to family planning services by unmarried people below the legal age of maturity; 2) the development of social institutions, such as exist in Thailand and the Philippines, to guide adolescents' behavior; 3) more extensive study of adolescent sexuality; 4) establishment of the scope of family policy.

    Minor histocompatibility (H) antigens are allogeneic target molecules having significant roles in alloimmune responses after human leukocyte antigenmatched solid organ and stem cell transplantation (SCT). Minor H antigens are instrumental in the processes of transplant rejection, graft-versus-host disease, and in the curative graft-versus-tumor effect of SCT. The latter characteristic enabled the current application of selected minor H antigens in clinical immunotherapeutic SCT protocols. No information exists on the global phenotypic distribution of the currently identified minor H antigens. Therefore, an estimation of their overall impact in human leukocyte antigenmatched solid organ and SCT in the major ethnic populations is still lacking. For the first time, a worldwide phenotype frequency analysis of ten autosomal minor H antigens was executed by 31 laboratories and comprised 2,685 randomly selected individuals from six major ethnic populations. Significant differences in minor H antigen frequencies were observed between the ethnic populations, some of which appeared to be geographically correlated. PMID:17604453

    Background Among women in the general population, childhood physical abuse (CPA) is associated with poor adult health status and engagement in health risk behaviors. Sexual minority women (SMW) are at elevated risk of CPA, have higher rates of smoking, and may be at higher risk for poorer general health. In this study, we examined the influences of CPA on health status in a diverse sample of SMW. We hypothesized that SMW with a history of CPA would report poorer health than those without such histories and that early onset of smoking–an important health risk behavior–would mediate the relationship between CPA and current health status. Methods Structural equation modeling was used to evaluate the influence of CPA on early health risk behavior (i.e., age of smoking onset) and current perceived health status in a community based sample of 368 SMW. Results More than one fifth of the sample (21.5%) reported a history of CPA. One fourth of the sample was current smokers; the average age of smoking onset was 19 to 20 years old. The mean level of self-rated health status was between “fair” and “good.” When relationships were simultaneously estimated, the effect of CPA on health status was mediated by two sequential smoking factors: CPA was associated with earlier age of smoking onset, and age of smoking onset was associated with current smoker status. Being a current smoker had a negative effect on perceived health status. Implications for Practice and/or Policy These results suggest that tobacco use is an important pathway by which CPA influences current health status. Prevention and early intervention initiatives should focus on the reduction of CPA among SMW to eliminate the long-term health consequences of adverse childhood events among SMW. PMID:23415321

  1. Polyandry and postcopulatory sexual selection in a wild population.

    When females mate multiply, postcopulatory sexual selection can occur via sperm competition and cryptic female choice. Although postcopulatory selection has the potential to be a major force in driving evolution, few studies have estimated its strength in natural populations. Likewise, although polyandry is widespread across taxa and is the focus of a growing body of research, estimates of natural female mating rates are still limited in number. Microsatellites can be used to estimate the number of mates represented in females' sperm stores and the number of sires contributing to their offspring, enabling comparisons both of polyandry and of two components of postcopulatory selection: the proportion of males that mate but fail to sire offspring, and the degree of paternity skew among the males that do sire offspring. Here, we estimate the number of mates and sires among wild females in the Hawaiian swordtail cricket Laupala cerasina. We compare these estimates to the actual mating rates and paternity shares we observed in a semi-natural population. Our results show that postcopulatory sexual selection operates strongly in this species: wild females mated with an average minimum of 3.6 males but used the sperm from only 58% of them. Furthermore, among the males that did sire offspring, paternity was significantly skewed. These patterns were similar to those observed in the field enclosure, where females mated with an average of 5.7 males and used the sperm from 62% of their mates, with paternity significantly skewed among the sires.

    Sex estimation is one of the first steps in forensic anthropology to identify human remains. In absence of the skull or the pelvis, any skeletal remain becomes fundamental for identification, especially in mass-disaster cases. The sternum is a potentially useful element in anthropological analysis with a high recovery rate in both forensic-and archaeological context. This study aims to develop classification functions for use in Spanish population. For this, sternum sexual dimorphism is studied in a sample of 105 individuals, known age-at-death, ancestry and sex, from San Jos Municipal Cemetery of Granada (Spain). Lin's concordance correlation coefficient was used to estimate intra-and inter-observer error. In discriminant analysis for estimating sex, cross-validation shows accuracy rates exceeds 90% for sternum body length and maximum width (91.8%), or total length with maximum width (90.7%). Isolated variables with higher accuracy rates are total sternum length (89.1%), and sternum body length (87%). Although there is compliance with Hyrtl's law it is not useful for estimating sex in Spanish population. These discriminant functions have also been validated successfully in two samples from Portugal (Coimbra identified skeletal collection--CISC, and 21st century identified ckeletal collection--Santarm XXI): the variables with higher accuracy rates sternum total length with its maximum width (92.3% the correctly classified individual in the sample CISC; and 83.5% in the sample of Santarm XXI) and the sternum total length (92.1% and 78.5%, respectively). The discriminant functions achieved with the collection of the San Jose cemetery of Granada can be applied to current remains, provided that study populations present a similar sexual dimorphism, like the two samples from Portuguese population presented in this study.

    The Women's Health Trial: Feasibility Study in Minority Populations (WHT:FSMP), a randomized trial of 2208 women, was conducted to investigate three questions. First, can women from minority and low-socioeconomic-status populations be recruited in numbers sufficient to evaluate a dietary intervention designed to lower fat intake. Second, the efficacy of a low fat, increased fruit/vegetable/ grain product intervention for reducing fat consumption. Third, will participation in the intervention lower plasma cholesterol and estradiol levels relative to the controls. The baseline results showed that an adequate number of minority and low SES women could be recruited to test the study hypotheses. A diverse study population of postmenopausal women consuming a high fat diet was recruited: 28% of participants were Black, 16% were Hispanic, 11% had less than a high school level of education, and 15.5% had household incomes of < $15,000.

    Racial/ethnic minority populations experience worse health outcomes than do other groups during and after disasters. Evidence for a differential impact from pandemic influenza includes both higher rates of underlying health conditions in minority populations, increasing their risk of influenza-related complications, and larger socioeconomic (e.g., access to health care), cultural, educational, and linguistic barriers to adoption of pandemic interventions. Implementation of pandemic interventions could be optimized by (1) culturally competent preparedness and response that address specific needs of racial/ethnic minority populations, (2) improvements in public health and community health safety net systems, (3) social policies that minimize economic burdens and improve compliance with isolation and quarantine, and (4) relevant, practical, and culturally and linguistically tailored communications.

    The relative strength of different types of directional selection has seldom been compared directly in natural populations. A recent meta-analysis of phenotypic selection studies in natural populations suggested that directional sexual selection may be stronger in magnitude than directional natural selection, although this pattern may have partly been confounded by the different time scales over which selection was estimated. Knowledge about the strength of different types of selection is of general interest for understanding how selective forces affect adaptive population divergence and how they may influence speciation. We studied divergent selection on morphology in parapatric, natural damselfly (Calopteryx splendens) populations. Sexual selection was stronger than natural selection measured on the same traits, irrespective of the time scale over which sexual selection was measured. Visualization of the fitness surfaces indicated that population divergence in overall morphology is more strongly influenced by divergent sexual selection rather than natural selection. Courtship success of experimental immigrant males was lower than that of resident males, indicating incipient sexual isolation between these populations. We conclude that current and strong sexual selection promotes adaptive population divergence in this species and that premating sexual isolation may have arisen as a correlated response to divergent sexual selection. Our results highlight the importance of sexual selection, rather than natural selection in the adaptive radiation of odonates, and supports previous suggestions that divergent sexual selection promotes speciation in this group.

    The reproductive and sexual health of adolescents is an important health concern and a focus of global attention. In Sri Lanka, a lack of understanding about adolescent reproductive and sexual health needs is a matter of national concern. A survey was undertaken to examine the sexual knowledge, attitudes and behaviours of school going adolescents in Sri Lanka. A random sample of schools was selected from one district. Data were collected by a self-completion questionnaire and analysed using SPSS. Response rate was 90%. 2020 pupils (26% boys, 74% girls) aged 16-19 years (mean=16.9) participated, the majority Sinhalese (97%). Most reported a good parent-child relationship (88%). A minority (34%) discussed sexual issues with parents. Health professionals were the preferred source of sexual information (32%) rather than parents (12.5%) or friends (5.6%). Less than 1% demonstrated satisfactory sexual and reproductive knowledge levels. 1.7% were sexually active (30 boys vs 5 girls), the majority with same age partners. 57% used contraception at first intercourse. There is an imperative to address the lack of sexual and reproductive knowledge. A minority of school going adolescents become sexually active. These individuals are potentially vulnerable and services need to be developed to meet their needs. PMID:25637417

    One of the most important characteristics in the survival of a species is related to the kind of reproduction responsible for the offspring generation. However, only in the last years the role played by sexual reproduction has been investigated. Then, for a better understanding of this kind of process we introduce, in this work, a surface reaction model that describes the role of the sexual reproduction. In our model two different elements of the species, representing male and female, can interact to reproduce a new element. The sex of this new element is chosen with a given probability and in order to take into account the mortality rate we introduce another kind of individual. The value of the spatial density of this element remains constant during the time evolution of the system. The model is studied using Monte Carlo simulations and mean field approximation. Depending on the values of the control parameters of the model, the system can attain two stationary states: In one of them the population survives and in the other it can be extinguished. Besides, accordingly to our results, the phase diagram of the model shows a discontinuous transition between these two states.

    Sexual conflict over reproductive investment can lead to sexually antagonistic coevolution and reproductive isolation. It has been suggested that, unlike most models of allopatric speciation, the evolution of reproductive isolation through sexually antagonistic coevolution will occur faster in large populations as these harbour greater levels of standing genetic variation, receive larger numbers of mutations and experience more intense sexual selection. We tested this in bruchid beetle populations (Callosobruchus maculatus) by manipulating population size and standing genetic variability in replicated lines derived from founders that had been released from sexual conflict for 90 generations. We found that after 19 generations of reintroduced sexual conflict, none of our treatments had evolved significant overall reproductive isolation among replicate lines. However, as predicted, measures of reproductive isolation tended to be greater among larger populations. We discuss our methodology, arguing that reproductive isolation is best examined by performing a matrix of allopatric and sympatric crosses whereas measurement of divergence requires crosses with a tester line.

    Given the heightened risk for HIV and other STIs among young men who have sex with men (YMSM) as well as the racial/ethnic disparities in HIV/STI risk, an understanding of longitudinal trends in sexual behaviors is warranted as YMSM emerge into adulthood. Drawing from an ongoing prospective cohort study, the present analysis employed latent growth curve modeling to examine trends in distinct types of sexual activity without condoms over time in sample of YMSM and examine differences by race/ethnicity and perceived familial socioeconomic status (SES). Overall, White and Mixed race YMSM reported more instances of oral sex without condoms as compared to other racial/ethnic groups with rates of decline over time noted in Black YMSM. White YMSM also reported more receptive and insertive anal sex acts without a condom than Black YMSM. Declines over time in both types of anal sex acts without condoms among Black men were noted when compared to White men, while increases over time were noted for mixed race YMSM for condomless insertive anal sex. The effects for race/ethnicity were attenuated with the inclusion of perceived familial SES in these models. These findings build on previous cross sectional studies showing less frequent sex without condoms among Black YMSM despite higher rates of HIV incidence in emerging adulthood, as well as the importance of considering economic conditions in such models. Efforts to understand racial/ethnic disparities in HIV/STIs among YMSM must move beyond examination of individual-level sexual behaviors and consider both race/ethnicity and socioeconomic conditions in order to evaluate how these factors shape the sexual behaviors of YMSM.

    We sought to quantify the association of social stressors with alcohol use among immigrant sexual and gender minority Latinos in North Carolina (n = 190). We modeled any drinking in past year using logistic regression and heavy episodic drinking in past 30 days using Poisson regression. Despite a large proportion of abstainers, there were indications of hazardous drinking. Among current drinkers, 63% reported at least one heavy drinking episode in past 30 days. Ethnic discrimination increased, and social support decreased, odds of any drinking in past year. Social support moderated the associations of English use and ethnic discrimination with heavy episodic drinking. PMID:24708429

    The understanding of natural and sexual selection requires both field and laboratory studies to exploit the advantages and avoid the disadvantages of each approach. However, studies have tended to be polarized among the types of organisms studied, with vertebrates studied in the field and invertebrates in the lab. We used video monitoring combined with DNA profiling of all of the members of a wild population of field crickets across two generations to capture the factors predicting the reproductive success of males and females. The factors that predict a male's success in gaining mates differ from those that predict how many offspring he has. We confirm the fundamental prediction that males vary more in their reproductive success than females, and we find that females as well as males leave more offspring when they mate with more partners.

    Background Tobacco use is the leading preventable cause of disease and death in the United States. Among racial and ethnic minorities, disparities in tobacco use, knowledge of health risks and treatment resources, access to and utilization of treatment contribute to a disproportionate disease burden from tobacco use. Furthermore, racial and ethnic minorities have been under-represented within tobacco treatment studies. Purpose/Objective This paper provides a review of published studies examining tobacco treatment interventions among ethnic and minority populations in the United States. Study Design/Methods Literature searches were used to identify smoking cessation interventions involving racial/ethnic minority populations. Identified studies were published between 1985 and 2009 involving African American, Latino, Native American, Asian or Pacific Islander smokers. Studies included in the review a) targeted one or more ethnic minority group or had at least 10 percent of study participants from ethnic minority groups and b) reported abstinence outcomes. Results Sixty-four studies were included in this review. Of studies meeting inclusion criteria, 28 included a primary focus on African Americans, 10 focused on Latinos, 4 focused on Native Americans, and 3 focused on Asian American smokers. An additional 19 studies reported samples including participants from more than one minority group. Sample inclusion criteria, intervention content and duration, follow-up, abstinence assessment, and limitations of these studies were reviewed. Conclusions Individuals from racial and ethnic minority populations are interested in stopping smoking and willing to participate in treatment research. Variations in the content of treatment intervention and study design produced a range of abstinence outcomes across studies. Additional research is needed for all groups, including African American smokers, and special attention is warranted for Latino, Native American, and Asian groups given the paucity of published studies. While there were limited evaluations of pharmacotherapy, the existing data support use of pharmacotherapy in addition to counseling for enhancing abstinence outcomes. Further attention to level of individual smoking, variability in smoking patterns, and use of other tobacco products is needed, given known variation within and between racial and ethnic groups. Overall, findings are consistent with recommendations from the 2008 Clinical Practice Guidelines calling for increased research devoted to evaluating and enhancing tobacco use treatment interventions among racial and ethnic minority populations.

    Contemporary prevention science has focused on the application of cultural adaptations of evidence-based prevention programs for minority youth populations. Far less is known about culturally grounded methods that are intended to organically develop prevention programs within specific populations and communities. This article systematically reviews recent literature on culturally grounded interventions used to prevent health disparities in ethnic minority youth populations. In this review, we assessed 31 peer-reviewed articles published in 2003 or later that fit inclusionary criteria pertaining to the development and evaluation of culturally grounded prevention programs. The evaluated studies indicated different approaches toward cultural grounding, as well as specific populations, geographic regions, and health issues that have been targeted. Specifically, the findings indicated that most of the studies focused on the development and evaluation of culturally grounded HIV/STI and substance abuse prevention programs for Mexican-American, African American, and American Indian/Alaska Native youth residing in the South or Southwestern US. These studies largely relied on community-based participatory or qualitative research methods to develop programs from the "ground up." This review has implications for the development of future culturally grounded and culturally adapted prevention programs targeting underserved minority youth populations and geographic regions. Specifically, it identifies populations and regions where culturally grounded prevention efforts are underdeveloped or non-existent, providing some scientific direction for the future development of these types of programs.

    Abstract In the United States, intimate partner violence (IPV) against women disproportionately affects ethnic minorities. Further, disparities related to socioeconomic and foreign-born status impact the adverse physical and mental health outcomes as a result of IPV, further exacerbating these health consequences. This article reviews 36 U.S. studies on the physical (e.g., multiple injuries, disordered eating patterns), mental (e.g., depression, post-traumatic stress disorder), and sexual and reproductive health conditions (e.g., HIV/STIs, unintended pregnancy) resulting from IPV victimization among ethnic minority (i.e., Black/African American, Hispanic/Latina, Native American/Alaska Native, Asian American) women, some of whom are immigrants. Most studies either did not have a sufficient sample size of ethnic minority women or did not use adequate statistical techniques to examine differences among different racial/ethnic groups. Few studies focused on Native American/Alaska Native and immigrant ethnic minority women and many of the intra-ethnic group studies have confounded race/ethnicity with income and other social determinants of health. Nonetheless, of the available data, there is evidence of health inequities associated with both minority ethnicity and IPV. To appropriately respond to the health needs of these groups of women, it is necessary to consider social, cultural, structural, and political barriers (e.g., medical mistrust, historical racism and trauma, perceived discrimination, immigration status) to patientprovider communication and help-seeking behaviors related to IPV, which can influence health outcomes. This comprehensive approach will mitigate the racial/ethnic and socioeconomic disparities related to IPV and associated health outcomes and behaviors. PMID:25551432

    Introduction The prevalence and associations of sexual bother in male medical students has not been extensively studied. Aims The aim of this study is to analyze predictors of sexual bother in a survey of male North American medical students. Methods Students enrolled in allopathic and osteopathic medical schools in North America between February 2008 and July 2008 were invited to participate in an internet-based survey of sexuality and sexual function. Main Outcome Measures The principle outcome measure was a single-item question inquiring about global satisfaction with sexual function. The survey also consisted of a questionnaire that included ethnodemographic factors, student status, sexual history, and a validated scale for the assessment of depression. Respondents completed the International Index of Erectile Function, the premature ejaculation diagnostic tool, and the Self-Esteem and Relationship Quality survey (SEAR). Descriptive statistics, analysis of variance, and multivariable logistic regression were utilized to analyze responses. Results There were 480 male subjects (mean age 26.3 years) with data sufficient for analysis. Forty-three (9%) reported sexual bother. Sexual bother was significantly more common in men with erectile dysfunction (ED), high risk of premature ejaculation (HRPE), depressive symptoms, and lower sexual frequency. However, after multivariate analysis including SEAR scores, ED, and HRPE were no longer independently predictive of sexual bother. Higher scores for all domains of the SEAR were associated with lower odds of sexual bother. Conclusions ED and HRPE are associated with sexual bother in this young and presumably healthy population. However, after controlling for relationship factors neither ED nor HRPE independently predicted sexual bother. It is plausible to hypothesize that sexual dysfunction from organic causes is rare in this population and is seldom encountered outside of relationship perturbations. Attention to relationship and psychological factors is likely of key importance in addressing sexual concerns in this population. PMID:21951580

  1. Women convicted of promoting prostitution of a minor are different from women convicted of traditional sexual offenses: a brief research report.

    Some jurisdictions have legally decreed that certain nonsexual offenses (e.g., promoting prostitution of a minor, arson, burglary) can be considered sexual offenses. Offenders convicted of these crimes can be subjected to sexual offender-specific social control policies such as registration, as well as be included in sexual offender research such as recidivism studies. No studies, however, have systematically examined differences and similarities between this new class of sexual offenders and more traditional sexual offenders. The current study used a sample of 94 women convicted of sexual offenses to investigate whether women convicted of promoting prostitution of a minor differed on demographic and criminogenic features from those convicted of more traditional sexual offenses. Results show that women convicted of promoting prostitution offenses have criminal histories more consistent with general criminality and exhibit more general antisocial features than women convicted of traditional sexual offenses. These results support the notion that the inclusion of legally defined sexual offenders with traditional ones obscures important differences in criminogenic features among these women. PMID:25336248

    Background: Sexuality is an important aspect of the personality of an individual and influences psychological, physical and social well-being of both men and women. It is a paradox, that in the country where kamasutra (by Vatsyayana) took birth, there is a lack of research publications and sexuality related literature; hence the current study was conducted, to estimate the prevalence and association of sexual disorders with various socio-demographic variables, in the selected rural population. Materials and Methods: Subjects who were sexually active and fulfilled the study criteria were administered Arizona Sexual Experience Scale as screening tool for the presence of sexual problems. Those who were found to be having sexual problems were interviewed further using appropriate questionnaires. Results: 21.15% of the male subjects were diagnosed to have one (or more) sexual disorder. Prevalence of erectile dysfunction was found to be 15.77%, male hypoactive sexual desire disorder (HSDD) 2.56%; premature ejaculation was found to be prevalent in 8.76% of the male subjects. Around 14% of the female subjects were diagnosed to have female sexual disorders. Prevalence of female arousal dysfunction was found to be 6.65%, female HSDD 8.87%, female anorgasmia 5.67%, female dyspareunia 2.34% and female sexual aversion disorder was found to be prevalent in 0.37% of the female subjects. Conclusion: This study concluded that one in five males and one in seven females were suffering from one (or more) sexual disorder. Improving the training of undergraduate medical and nursing students in sexuality related issues, increasing trained individuals in sexual medicine by starting new courses, providing sex education to the general population using media and merging sexual health care with primary care, are likely to play a significant role in addressing the increasing sexual health morbidity.

    Diabetes is the sixth leading cause of death in the United States and it is now cited along with obesity as a global epidemic. Significant racial/ethnic disparities exist in the prevalence of diabetes within the US, with racial and ethnic minorities disproportionately affected by type 2 diabetes and its complications. Racial/ethnic and socioeconomic factors influence the development and course of diabetes at multiple levels, including genetic, individual, familial, community and national. From an ecodevelopmental perspective, cultural variables assessed at one level (e.g., family level dietary practices) may interact with other types of variables examined at other levels (e.g., the availability of healthy foods within a low-income neighborhood), thus prompting the need for a clear analysis of these systemic relationships as they may increase risks for disease. Therefore, the need exists for models that aid in “mapping out” these relationships. A more explicit conceptualization of such multi-level relationships would aid in the design of culturally relevant interventions that aim to maximize effectiveness when applied with Latinos and other racial/ethnic minority groups. This paper presents an expanded ecodevelopmental model intended to serve as a tool to aid in the design of multi-level diabetes prevention interventions for application with racial/ethnic minority populations. This discussion focuses primarily on risk factors and prevention intervention in Latino populations, although with implications for other racial/ethnic minority populations that are also at high risk for type 2 diabetes.

    Asexual reproduction avoids the costs associated with sex, predicting that invading asexual clones can quickly replace sexual populations. Daphnia pulex populations in the Great Lakes area are predominately asexual, but the elimination of sexual populations by invading clones is poorly understood. Asexual clones were detected at low frequency in one rare sexual population in 1995, with some increase in frequency during 2003 and 2004. However, these clones remained at low frequency during further yearly sampling (2005-2013) with no evidence that the resident sexual population was in danger of elimination. There was evidence for hybridization between rare males produced by asexual clones and sexual females with the potential to produce new asexual genotypes and spread the genetic factors for asexuality. In a short-term laboratory competition experiment, the two most common asexual clones did not increase in frequency relative to a genetically diverse sexual population due in part to a greater investment in diapausing eggs that trades-off current population growth for increased contribution to the egg bank. Our results suggest that a successful invasion can be prolonged, requiring a combination of clonal genotypes with high fitness, persistence of clones in the egg bank and negative factors affecting the sexual population such as inbreeding depression resulting from population bottlenecks.

    Objective The recruitment of minority and underserved individuals to research studies is often problematic. The purpose of this study was to describe the recruitment experiences of projects that actively recruited minority and underserved populations as part of The Centers for Population Health and Health Disparities (CPHHD) initiative. Methods Principal investigators and research staff from 17 research projects at eight institutions across the United States were surveyed about their recruitment experiences. Investigators reported the study purpose and design, recruitment methods employed, recruitment progress, problems or challenges to recruitment, strategies used to address these problems, and difficulties resulting from Institutional Review Board (IRB) or Health Insurance Portability and Accountability Act of 1996 (HIPAA) requirements. Additionally, information was collected about participant burden and compensation. Burden was classified on a three-level scale. Recruitment results were reported as of March 31, 2007. Results Recruitment attainment ranged from 52% to 184% of the participant recruitment goals. Commonly reported recruitment problems included administrative issues, and difficulties with establishing community partnerships and contacting potential participants. Long study questionnaires, extended follow-up, and narrow eligibility criteria were also problematic. The majority of projects reported difficulties with IRB approvals, though few reported issues related to HIPAA requirements. Attempted solutions to recruitment problems varied across Centers and included using multiple recruitment sites and sources and culturally appropriate invitations to participate. Participant burden and compensation varied widely across the projects, however, accrual appeared to be inversely associated with the amount of participant burden for each project. Conclusion Recruitment of minority and underserved populations to clinical trials is necessary to increase study generalizbility and reduce health disparities. Our results demonstrate the importance of flexible study designs which allow adaptation to recruitment challenges. These experiences also highlight the importance of involving community members and reducing participant burden to achieve success in recruiting individuals from minority and underserved populations.

    African American and Latino young men who have sex with men (YMSM) are at the forefront of the U.S. HIV epidemic. As members of the cellular generation, these youth are very likely to use text messaging; yet, relatively little research has explored use of text messaging as a tool for sexual health promotion, particularly among racial ethnic minorities who are also sexual minorities. We report on the results of ten focus groups conducted among African American and Latino YMSM, aged 1825, regarding their current texting practices and the feasibility/acceptability of text messaging as a means of conducting sexual health promotion. Our analyses revealed four main themes around their texting behaviors, texting preferences, perceived advantages/disadvantages of texting, and the etiquette of texting. We consider implications of these findings for the development of texting-based sexual health promotion interventions, particularly in conjunction with other existing interventions operating in a new risk environment.

    Background Those who go online regarding their sexual health are potential users of new Internet-based sexual health interventions. Understanding the size and characteristics of this population is important in informing intervention design and delivery. Objective We aimed to estimate the prevalence in Britain of recent use of the Internet for key sexual health reasons (for chlamydia testing, human immunodeficiency virus [HIV] testing, sexually transmitted infection [STI] treatment, condoms/contraceptives, and help/advice with one’s sex life) and to identify associated sociodemographic and behavioral factors. Methods Complex survey analysis of data from 8926 sexually experienced persons aged 16-44 years in a 2010-2012 probability survey of Britain’s resident population. Prevalence of recent (past year) use of Internet sources for key sexual health reasons was estimated. Factors associated with use of information/support websites were identified using logistic regression to calculate age-adjusted odds ratios (AORs). Results Recent Internet use for chlamydia/HIV testing or STI treatment (combined) was very low (men: 0.31%; women: 0.16%), whereas 2.35% of men and 0.51% of women reported obtaining condoms/contraceptives online. Additionally, 4.49% of men and 4.57% of women reported recent use of information/support websites for advice/help with their sex lives. Prevalence declined with age (men 16-24 years: 7.7%; 35-44 years: 1.84%, P<.001; women 16-24 years: 7.8%; 35-44 years: 1.84%, P<.001). Use of information/support websites was strongly associated with men’s higher socioeconomic status (managerial/professional vs semiroutine/routine: AOR 1.93, 95% CI 1.27-2.93, P<.001). Despite no overall association with area-level deprivation, those in densely populated urban areas were more likely to report use of information/support websites than those living in rural areas (men: AOR 3.38, 95% CI 1.68-6.77, P<.001; women: AOR 2.51, 95% CI 1.34-4.70, P<.001). No statistically significant association was observed with number of sex partners reported after age adjustment, but use was more common among men reporting same-sex partners (last 5 years: AOR 2.44, 95% CI 1.27-4.70), women reporting sex with multiple partners without condoms (last year: AOR 1.90, 95% CI 1.11-3.26), and, among both sexes, reporting seeking sex online (last year, men: AOR 1.80, 95% CI 1.16-2.79; women: AOR 3.00, 95% CI 1.76-5.13). No association was observed with reporting STI diagnosis/es (last 5 years) or (after age adjustment) recent use of any STI service or non-Internet sexual health seeking. Conclusions A minority in Britain used the Internet for the sexual health reasons examined. Use of information/support websites was reported by those at greater STI risk, including younger people, indicating that demand for online STI services, and Internet-based sexual health interventions in general, may increase over time in this and subsequent cohorts. However, the impact on health inequalities needs addressing during design and evaluation of online sexual health interventions so that they maximize public health benefit. PMID:26792090

    Of the more than 300 octopus species, Octopus minor is one of the most popular and economically important species in Eastern Asia, including Korea, along with O. vulgaris, O. ocellatus, and O. aegina. We developed 19 microsatellite markers from Octopus minor and eight polymorphic markers were developed to analyze the genetic diversity and relationships among four octopus populations from Korea and three from China. The number of alleles per locus varied from 10 to 49, and allelic richness per locus ranged from 2 to 16.4 across all populations. The average allele number among the populations was 11.1, with a minimum of 8.3 and a maximum of 13.6. The mean allelic richness was 8.7 in all populations. The Hardy-Weinberg equilibrium (HWE) test revealed significant deviation in 19 of the 56 single-locus sites, and null alleles were presumed in five of eight loci. The pairwise F ( ST ) values between populations from Korea and China differed significantly in all pairwise comparisons. The genetic distances between the China and Korea samples ranged from 0.161 to 0.454. The genetic distances among the populations from Korea ranged from 0.033 to 0.090, with an average of 0.062; those among populations from China ranged from 0.191 to 0.316, with an average of 0.254. The populations from Korea and China formed clearly separated into clusters via an unweighted pair group method with arithmetic mean dendrogram. Furthermore, a population from muddy flats on the western coast of the Korean Peninsula and one from a rocky area on Jeju Island formed clearly separated subclusters. An assignment test based on the allele distribution discriminated between the Korean and Chinese origins with 96.9 % accuracy. PMID:22707143

    BACKGROUND Whereas dating violence among high school students has been linked with sexual risk-taking and substance use, this association has been understudied among early adolescents. We estimated the prevalence of physical and nonphysical dating violence in a sample of middle school students and examined associations between dating violence, sexual, and substance use behaviors. METHODS Logistic regression models for clustered data from 7th grade students attending 10 Texas urban middle schools were used to examine cross-sectional associations between dating violence victimization and risk behaviors. RESULTS The sample (N = 950) was 48.5% African American, 36.0% Hispanic, 55.7% female, mean age 13.1 years (SD 0.64). About 1 in 5 reported physical dating violence victimization, 48.1% reported nonphysical victimization, and 52.6% reported any victimization. Adjusted logistic regression analyses indicated that physical, nonphysical, and any victimization was associated with ever having sex, ever using alcohol, and ever using drugs. CONCLUSIONS Over 50% of sampled middle school students had experienced dating violence, which may be associated with early sexual initiation and substance use. Middle school interventions that prevent dating violence are needed. PMID:23586886

    RNA viruses within infected individuals exist as a population of evolutionary-related variants. Owing to evolutionary change affecting the constitution of this population, the frequency and/or occurrence of individual viral variants can show marked or subtle fluctuations. Since the development of massively parallel sequencing platforms, such viral populations can now be investigated to unprecedented resolution. A critical problem with such analyses is the presence of sequencing-related errors that obscure the identification of true biological variants present at low frequency. Here, we report the development and assessment of the Quality Assessment of Short Read (QUASR) Pipeline (http://sourceforge.net/projects/quasr) specific for virus genome short read analysis that minimizes sequencing errors from multiple deep-sequencing platforms, and enables post-mapping analysis of the minority variants within the viral population. QUASR significantly reduces the error-related noise in deep-sequencing datasets, resulting in increased mapping accuracy and reduction of erroneous mutations. Using QUASR, we have determined influenza virus genome dynamics in sequential samples from an in vitro evolution of 2009 pandemic H1N1 (A/H1N1/09) influenza from samples sequenced on both the Roche 454 GSFLX and Illumina GAIIx platforms. Importantly, concordance between the 454 and Illumina sequencing allowed unambiguous minority-variant detection and accurate determination of virus population turnover in vitro. PMID:23382427

    2016-02-01

    The purpose of this study was to understand which social context factors most influence depression symptomology among sexual minority male youth (SMMY). In 2011, 195 SMMY who use Grindr were recruited to complete an online survey in Los Angeles, California. Items focused on social context variables and depression symptomology. Hierarchical multiple regressions were conducted using an ecological framework. The best fitting model accounted for 29.5% of the variance in depression. Experiences of homophobia, gay community connection, presence of an objecting network member, and emotional support were found to be significant predictors. Past experiences of homophobia continuing to affect youth indicates the need for intervention to reduction of homophobia in youths' social contexts. Interventions that teach youth skills to manage objecting viewpoints or help youth to reorganize their social networks may help to reduce the impact of an objecting network alter. PMID:26295497

    Coming out is a significant and sometimes difficult process in the lives of sexual minorities, but disclosure can also affect wellbeing in positive ways, including reduced distress and greater relationship satisfaction. This study investigates the possibility of stress-related growth and depreciation following coming out. To obtain a diverse sample with varying coming-out experiences, data were collected from undergraduate students as well as from online sources, including lesbian, gay, and bisexual support groups and Pride groups. Regression analyses indicated that negative social reactions to coming out predicted both growth and depreciation, although they more strongly predicted depreciation. Positive social reactions were positively related to stress-related growth, while internalized homonegativity was inversely associated with growth. Although the two sample sources (online and campus) differed in some ways, sample source was not a significant predictor in the regressions, nor was it indicated as a moderator in exploratory ANOVA analyses.

    Background Physical activity is an important health determinant. Little is known about sexual orientation differences in physical activity and their psychosocial determinants. Purpose To examine adolescent and young adult hours/week of moderate/vigorous physical activity (MVPA) and team sports participation by sexual orientation and investigate contributions of gender nonconformity and low athletic self-esteem to possible sexual orientation differences. Methods Analysis of data from 5,272 males and 7,507 females from 1999-2005 waves of the US Growing Up Today Study (ages 12-22 years). Results Sexual minorities (i.e., lesbian, gay, bisexual, mostly heterosexual) reported 1.21-2.62 hours/week less MVPA (p's<0.01) and were 46%-76% less likely to participate in team sports than same-gender heterosexuals. Gender nonconformity and athletic self-esteem accounted for 46%-100% of sexual orientation MVPA differences. Conclusions Physical activity contexts should be modified to welcome sexual minority males and females. Targeting intolerance of gender nonconformity and fostering athletic self-esteem may mitigate sexual orientation MVPA disparities. PMID:24347406

    The Roma (Gypsy) are the largest European minority population characterized by poverty, social exclusion as well as by numerous life-style and cultural specificities, which all could have an adverse impact on their cardiovascular health. This study assesses the prevalence of cardiovascular diseases (CVD) risk factors in community-based sample of 430 adult Roma, living in rural area of Croatia, by providing the actual and age-adjusted estimates using the European standard population. The most prominent classical CVD risk phenotypes (blood pressure, obesity, smoking, glucose and lipid profile) were selected, and the standard risk cut-offs were applied. The study has shown that compared to general population of Croatia, the Roma population bears a high CVD risk factors load related to smoking and high glucose level. The CVD risk factors prevalence in Roma also showed important sex and age patterns, the most imposing of which are the findings of higher prevalence of CVD risks in women (especially obesity and triglyceride levels) and the trend of higher body mass index (BMI) level in younger age group (18-34 years) which both stand in contrast to the trends characterizing the general population of Croatia. These findings are complemented by the trend of decreased risk in the oldest age group (65+ years) for all investigated CVD risk factors (with exception of triglycerides level) compared to the 50-64 age group. We conclude that the age and sex CVD risks pattern point to the health transition of this rural Roma population. As we expect the proportion of CVD in the Roma minority of Croatia to increase in the future along with further modernization of their lifestyle, the CVD prevention measures in this population are urgent and should be primarily targeted at women and at the younger segment of this population.

  8. Sexual conflict and the gender load: correlated evolution between population fitness and sexual dimorphism in seed beetles

    Although males and females share much of the same genome, selection is often distinct in the two sexes. Sexually antagonistic loci will in theory cause a gender load in populations, because sex-specific selection on a given trait in one sex will compromise the adaptive evolution of the same trait in the other sex. However, it is currently not clear whether such intralocus sexual conflict (ISC) represents a transient evolutionary state, where conflict is rapidly resolved by the evolution of sexual dimorphism (SD), or whether it is a more chronic impediment to adaptation. All else being equal, ISC should manifest itself as correlated evolution between population fitness and SD in traits expressed in both sexes. However, comparative tests of this prediction are problematic and have been unfeasible. Here, we assess the effects of ISC by comparing fitness and SD across distinct laboratory populations of seed beetles that should be well adapted to a shared environment. We show that SD in juvenile development time, a key life-history trait with a history of sexually antagonistic selection in this model system, is positively related to fitness. This effect is due to a correlated evolution between population fitness and development time that is positive in females but negative in males. Loosening the genetic bind between the sexes has evidently allowed the sexes to approach their distinct adaptive peaks. PMID:20031994

    Smoking rates are higher among lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals than among heterosexuals. These disparities are exacerbated during the transition from youth to young adulthood. The current study uses in-depth qualitative interviews to understand perceptions of LGBTQ smoking among LBQ-identified women (N=30, ages 18-24). Major themes identified include the belief that smoking was a way of overcoming stressors faced by heterosexual and LGBTQ young adults alike, a mechanism to relieve sexuality-related stressors, and an ingrained part of LGBTQ culture. Results suggest unique stressors influence LGBTQ smokers. Implications for smoking cessation interventions for LGBTQ youth are discussed. PMID:26508993

    This review surveys the literature published on the characteristics and implications of pre-diabetes and type 2 diabetes mellitus (T2DM) for the Arab and Bedouin populations of Israel. T2DM is a global health problem. The rapid rise in its prevalence in the Arab and Bedouin populations in Israel is responsible for their lower life expectancy compared to Israeli Jews. The increased prevalence of T2DM corresponds to increased rates of obesity in these populations. A major risk group is adult Arab women aged 55-64 years. In this group obesity reaches 70%. There are several genetic and nutritional explanations for this increase. We found high hospitalization rates for micro and macrovascular complications among diabetic patients of Arab and Bedouin origin. Despite the high prevalence of diabetes and its negative health implications, there is evidence that care and counseling relating to nutrition, physical activity and self-examination of the feet are unsatisfactory. Economic difficulties are frequently cited as the reason for inadequate medical care. Other proposed reasons include faith in traditional therapy and misconceptions about drugs and their side effects. In Israel, the quality indicators program is based on one of the world’s leading information systems and deals with the management of chronic diseases such as diabetes. The program’s baseline data pointed to health inequality between minority populations and the general population in several areas, including monitoring and control of diabetes. Based on these data, a pilot intervention program was planned, aimed at minority populations. This program led to a decrease in inequality and served as the basis for a broader, more comprehensive intervention that has entered the implementation stage. Interventions that were shown to be effective in other Arabic countries may serve as models for diabetes management in the Arab and Bedouin populations in Israel. PMID:25685290

    Sexual behaviors in China are rapidly changing; simultaneously, STI/HIV prevalence is increasing in the general population. To investigate these major shifts, we examined sexual behaviors and self-reported sexually transmitted infections (STI) in one prefectural city in southern China, Liuzhou, and compared it to other prefectural cities throughout China. We used adults age 18-39 from two sets of population-based surveys that paralleled each other in both content and method. The first set was the Liuzhou survey conducted in 2008 (n=398). The second set consisted of two national surveys collected in 2006 and 2010 (n=2186). Liuzhou respondents reported more active social and sexual behaviors than their national counterparts, including more socializing, dancing, drinking excessively, sexual activity among never married men and women, purchasing commercial sex among men, one-night stands among men, multiple sexual partnerships and self-reported STI among both men and women. Women in Liuzhou reported greater sexual risk behavior than their national counterparts, although overall they reported less than their male counterparts; they were also more likely to have had an abortion than women in other prefectural cities. Our findings provide a comprehensive overview of the sexual context of Liuzhou among the general population, which may help explain the greater STI/HIV prevalence in Liuzhou. PMID:24174289

    The rate of treated end-stage renal disease (ESRD) continues to increase globally. The disproportionately high rate of ESRD among the many growing indigenous populations and racial/ethnic minorities in the United States highlights the need to reassess present treatment strategies to more appropriately identify and manage chronic kidney disease in diverse communities. Similar projections have been noted worldwide. This discrepancy between ESRD rates among racial and ethnic minority groups, and treatment strategies is due to several factors, many of which are modifiable. These include the individual, the health care provider/system, and limited participation in controlled clinical trials. Although it is unfortunate that this disparity continues to exist, a thoughtful and compassionate approach to addressing the role of diverse biobehavioral and sociocultural factors might be the key to effective translation of emerging scientific advances into improved clinical outcomes for all patients with chronic kidney disease.

    Verbal/psychological homophobic bullying is widespread among youths of sexual minorities. Homophobic bullying has been associated with both high internalized homophobia and low self-esteem. The objectives were to document verbal/psychological homophobic bullying among youths of sexual minorities and model the relationships between homophobic bullying, internalized homophobia and self-esteem. A community sample of 300 youths of sexual minorities aged 14 to 22 years old was used. A structural equation model was tested using a nonlinear, robust estimator implemented in Mplus. The model postulated that homophobic bullying impacts self-esteem both directly and indirectly, via internalized homophobia. 60.7% of the sample reported at least one form of verbal/psychological homophobic bullying. The model explained 29% of the variance of self-esteem, 19.6% of the variance of internalized homophobia and 5.3% of the verbal/psychological homophobic bullying. The model suggests that the relationship between verbal/psychological homophobic bullying and self-esteem is partially mediated by internalized homophobia. The results underscore the importance of initiatives to prevent homophobic bullying in order to prevent its negative effects on the well-being of youths of sexual minorities. PMID:24714888

    Introduction Given changes in sexual behaviors and norms in the United States, there is a need for current and representative data on sexual behaviors with particular interest in gender, age, and racial/ethnic group differences. Aim Given the limited data for Hispanics and for Puerto Rico (PR), we described patterns of sexual behaviors and characteristics among a sexually active sample (n = 1,575) of adults aged 2164 years in PR. Main Outcome Measures The main outcome measures for this study are sexual behaviors including age at sexual initiation, number of sexual partners, vaginal and anal intercourse, and oral sex, among others. Methods Data from a population-based cross-sectional study in PR (20052008) was analyzed. The prevalence of sexual behaviors and characteristics was described by age-group and gender during the lifetime and in the past 12 months. Results Overall, 96.8%, 81.6%, and 60.9% of participants had ever engaged in vaginal, oral and anal sex, respectively, whereas 23.7% were seropositive to any of the sexually transmitted infections under study. Sexual initiation ?15 years was reported by 37.8% of men and 21.4% of women; whereas 47.9% of men and 13.2% of women reported to have had ?7 sexual partners in their lifetime. Approximately, 3% of women and 6% of men reported same-sex sexual practices, while history of forced sexual relations was reported by 9.6% of women and 2.5% of men. Sexual initiation ?15 years was more common among individuals aged 2134 years (41.4% men and 33.6% women) as compared with older cohorts. Although having had ?7 sexual partners over a lifetime among men was similar across age groups, this behavior decreased in older women cohorts. In both genders, the prevalence of oral and anal sex was also lower in the older age cohorts. Conclusion This study provides essential information than can help health professionals understand the sexual practices and needs of the population of PR. PMID:21676177

    Vicarious traumatization of nonvictim members of communities targeted by bias crimes has been suggested by previous qualitative studies and often dominates public discussion following bias events, but proximal and distal responses of community members have yet to be comprehensively modeled, and quantitative research on vicarious responses is scarce. This comprehensive review integrates theoretical and empirical literatures in social, clinical, and physiological psychology in the development of a model of affective, cognitive, and physiological responses of lesbian, gay, and bisexual individuals upon exposure to information about bias crimes. Extant qualitative research in vicarious response to bias crimes is reviewed in light of theoretical implications and methodological limitations. Potential pathways to mental health outcomes are outlined, including accumulative effects of anticipatory defensive responding, multiplicative effects of minority stress, and putative traumatogenic physiological and cognitive processes of threat. Methodological considerations, future research directions, and clinical implications are also discussed. PMID:24626458

    Background Several studies suggest yoga may be effective for chronic low back pain; however, trials targeting minorities have not been conducted. Primary Study Objectives Assess the feasibility of studying yoga in a predominantly minority population with chronic low back pain. Collect preliminary data to plan a larger powered study. Study Design Pilot randomized controlled trial. Setting Two community health centers in a racially diverse neighborhood of Boston, Massachusetts. Participants Thirty English-speaking adults (mean age 44 years, 83% female, 83% racial/ethnic minorities; 48% with incomes ?$30000) with moderate-to-severe chronic low back pain. Interventions Standardized series of weekly hatha yoga classes for 12 weeks compared to a waitlist usual care control. Outcome Measures Feasibility measured by time to complete enrollment, proportion of racial/ethnic minorities enrolled, retention rates, and adverse events. Primary efficacy outcomes were changes from baseline to 12 weeks in pain score (0=no pain to 10=worst possible pain) and back-related function using the modified Roland-Morris Disability Questionnaire (023 point scale, higher scores reflect poorer function). Secondary efficacy outcomes were analgesic use, global improvement, and quality of life (SF-36). Results Recruitment took 2 months. Retention rates were 97% at 12 weeks and 77% at 26 weeks. Mean pain scores for yoga decreased from baseline to 12 weeks (6.7 to 4.4) compared to usual care, which decreased from 7.5 to 7.1 (P=.02). Mean Roland scores for yoga decreased from 14.5 to 8.2 compared to usual care, which decreased from 16.1 to 12.5 (P=.28). At 12 weeks, yoga compared to usual care participants reported less analgesic use (13% vs 73%, P=.003), less opiate use (0% vs 33%, P=.04), and greater overall improvement (73% vs 27%, P=.03). There were no differences in SF-36 scores and no serious adverse events. Conclusion A yoga study intervention in a predominantly minority population with chronic low back pain was moderately feasible and may be more effective than usual care for reducing pain and pain medication use.

    ABSTRACT To understand the geographical distribution of lettuce drop incidence and the structure of Sclerotinia minor and S. sclerotiorum populations, commercial lettuce fields were surveyed in the Salinas, San Joaquin, and Santa Maria Valleys in California. Lettuce drop incidence, pathogen species, and mycelial compatibility groups (MCGs) were determined and analyzed using geostatistic and geographical information system tools. Lettuce drop incidence was lowest in the San Joaquin Valley, and not significantly different between the other two valleys. Semivariogram analysis revealed that lettuce drop incidence was not spatially correlated between different fields in the Salinas Valley, suggesting negligible field-to-field spread or influence of inoculum in one field on other fields. Lettuce drop incidence was significantly lower in fields with a surface drip system than in fields with furrow or sprinkler irrigation systems, suggesting that the surface drip system can be a potential management measure for reducing lettuce drop. In the San Joaquin Valley, S. sclerotiorum was the prevalent species, causing drop in 63.5% of the fields, whereas S. minor also was identified in 25.4% of the fields. In contrast, in the Salinas Valley, S. minor was the dominant species (76.1%) whereas S sclerotiorum only observed in only 13.6% fields, in which only a few plants were infected by S. sclerotiorum. In the Santa Maria Valley, both species frequently were identified, with S. minor being slightly more common. Although many MCGs were identified in S. minor, most of them consisted of only one or two isolates. In all, approximately 91.4% of the isolates belonged to four MCGs. Among them, MCG-1 was the most prevalent group in all three valleys, accounting for 49.8% of total isolates. It was distributed all over the surveyed areas, whereas other MCGs were distributed more or less locally. Populations of S. sclerotiorum exhibited greater diversity, with 89 isolates collected from the Salinas and San Joaquin Valleys belonging to 37 different MCGs. Among them, the most recurrent MCG-A contained 16 isolates, and 30 MCGs contained only 1 isolate each. Many MCGs occurred within only one or a part of the two valleys. Potential reasons for this abundant diversity are discussed. PMID:18943664

    2012-02-01

    The aim of this study was to test some of the main hypotheses derived from Buss' Sexual Strategies Theory on a representative Spanish sample. These hypotheses refer to the different strategies men and woman seem to adopt when they want to engage in a short-term sexual relationship (fling), or in a long-term one (loving relationship). (The technical term "strategies", unlike its equivalent in everyday language, is not meant to imply something necessarily planned or conscious). Data was obtained by self-report from a representative sample of 1949 Spanish people. Almost all the results verify the working hypotheses, conferring some empirical support on the theory from which they were deduced, within an evolutionary Social Psychology paradigm. In any case, it is argued that socialization approaches ("double moral" and the social construction of gender role and sexual identity) can also explain most of the differences obtained, in perfect compatibility with biological perspectives.

    People of lower-socioeconomic position (SEP) and most racial/ethnic minorities face significant communication challenges which may negatively impact their health. Previous research has shown that these groups rely heavily on interpersonal sources to share and receive health information; however, little is known about these lay sources. The purpose of this paper is to apply the concept of a market maven to the public health sector with the aims of identifying determinants of high health information mavenism among low-SEP and racial/ethnic minority groups and to assess the information they may be sharing based on their own health beliefs. Data for this study were drawn from the baseline survey (n=325) of a US randomized control intervention study aimed at eliciting an understanding of Internet-related challenges among lower-SEP and minority individuals. Regression models were estimated to distinguish significant determinants of health information mavenism among the sample. Similarly, bivariate and logistic multivariable models were estimated to determine the association between health information mavenism and accurate health beliefs relating to diet, physical activity and smoking. The data illustrate that having a larger social network, being female and being older were important factors associated with higher mavenism scores. Additionally being a moderate consumer of general media as well as fewer years in the US and lower language acculturation were significant predictors of higher mavenism scores. Mavens were more likely than non-mavens to maintain accurate beliefs regarding diet; however, there was no distinction between physical activity and smoking beliefs between mavens and non-mavens. These results offer a unique understanding of health information mavenism which could better leverage word-of-mouth health communication efforts among lower-SEP and minority groups in order to reduce communication inequalities. Moreover, the data indicate that health information mavens may serve as an ideal point of intervention in attempts to modify health beliefs with the goal of reducing health disparities among these populations.

    People of lower-socioeconomic position (SEP) and most racial/ethnic minorities face significant communication challenges which may negatively impact their health. Previous research has shown that these groups rely heavily on interpersonal sources to share and receive health information; however, little is known about these lay sources. The purpose of this paper is to apply the concept of a market maven to the public health sector with the aims of identifying determinants of high health information mavenism among low-SEP and racial/ethnic minority groups and to assess the information they may be sharing based on their own health beliefs. Data for this study were drawn from the baseline survey (n = 325) of a US randomized control intervention study aimed at eliciting an understanding of Internet-related challenges among lower-SEP and minority individuals. Regression models were estimated to distinguish significant determinants of health information mavenism among the sample. Similarly, bivariate and logistic multivariable models were estimated to determine the association between health information mavenism and accurate health beliefs relating to diet, physical activity and smoking. The data illustrate that having a larger social network, being female and being older were important factors associated with higher mavenism scores. Additionally being a moderate consumer of general media as well as fewer years in the US and lower language acculturation were significant predictors of higher mavenism scores. Mavens were more likely than non-mavens to maintain accurate beliefs regarding diet; however, there was no distinction between physical activity and smoking beliefs between mavens and non-mavens. These results offer a unique understanding of health information mavenism which could better leverage word-of-mouth health communication efforts among lower-SEP and minority groups in order to reduce communication inequalities. Moreover, the data indicate that health information mavens may serve as an ideal point of intervention in attempts to modify health beliefs with the goal of reducing health disparities among these populations.

  9. Germline Selection: Population Genetic Aspects of the Sexual/Asexual Life Cycle

    Population geneticists make a distinction between sexual and asexual organisms depending on whether individuals inherit genes from one or two parents. When individual genes are considered, this distinction becomes less satisfactory for multicellular sexual organisms. Individual genes pass through numerous asexual mitotic cell divisions in the germline prior to meiosis and sexual recombination. The processes of mitotic mutation, mitotic crossing over, and mitotic gene conversion create genotypic diversity between diploid cells in the germline. Genes expressed in the germline whose products affect cell viability (such as many ``housekeeping'' enzymes) may be subjected to natural selection acting on this variability resulting in a non-Mendelian output of gametes. Such genes will be governed by the population genetics of the sexual/asexual life cycle rather than the conventional sexual/Mendelian life cycle. A model is developed to investigate some properties of the sexual/asexual life cycle. When appropriate parameter values were included in the model, it was found that mutation rates per locus per gamete may vary by a factor of up to 100 if selection acts in the germline. Sexual/asexual populations appear able to evolve to a genotype of higher fitness despite intervening genotypes of lower fitness, reducing the problems of underdominance and Wright's adaptive landscape encountered by purely sexual populations. As might be expected this ability is chiefly determined by the number of asexual mitotic cell divisions within the germline. The evolutionary consequences of ``housekeeping'' loci being governed by the dynamics of the sexual/asexual life cycle are considered. PMID:1783297

    Background To our knowledge, there is no well-articulated process for the design of culturally informed behavioral intervention technologies. Objective This paper describes the early stages of such a process, illustrated by the methodology for the ongoing development of a behavioral intervention technology targeting generalized anxiety disorder and major depression among young sexual minority men. Methods We integrated instructional design for Internet behavioral intervention technologies with greater detail on information sources that can identify user needs in understudied populations, as well as advances in the understanding of technology-specific behavioral intervention technology dimensions that may need to be culturally tailored. Results General psychological theory describing how to effect change in the clinical target is first integrated with theory describing potentially malleable factors that help explain the clinical problem within the population. Additional information sources are then used to (1) evaluate the theory, (2) identify population-specific factors that may affect users ability to relate to and benefit from the behavioral intervention technology, and (3) establish specific skills, attitudes, knowledge, etc, required to change malleable factors posited in the theory. User needs result from synthesis of this information. Product requirements are then generated through application of the user needs to specific behavioral intervention technology dimensions (eg, technology platform). We provide examples of considerations relevant to each stage of this process and how they were applied. Conclusions This process can guide the initial design of other culturally informed behavioral intervention technologies. This first attempt to create a systematic design process can spur development of guidelines for design of behavioral intervention technologies aimed to reduce health disparities. PMID:24311444

    Asia minor bluegrass (Polypogon fugax) is a common annual grass weed of winter crops distributed across China. We conducted a study on the resistance level and the mechanism of resistance to ACCase-inhibiting herbicides in a P. fugax population from China. Whole-plant dose-response experiments in greenhouse showed that the resistant P. fugax population was 1991, 364, 269, 157, and 8-fold resistant to clodinafop-propargyl, fluazifop-p-butyl, haloxyfop-R-methyl, quizalofop-p-ethyl and fenoxaprop-p-ethyl relative to the reference susceptible population, which was susceptible to all the five AOPP herbicides. Much lower R/S values of 3.5, 2.4 and 3.5, respectively, were detected for clethodim, sethoxydim and pinoxaden. Molecular analysis of resistance confirmed that the Ile2041 to Asn mutation in the resistant population conferred resistance to AOPP herbicides, but not to CHD and DEN herbicides. This is the first report of a target site mutation that corresponded to resistance to AOPP herbicides in P. fugax. Proper resistance management practices are necessary to prevent ACCase-inhibiting herbicides from becoming ineffective over wide areas. PMID:24485310

    Despite many recent advances in rights for sexual and gender minorities in the United States, bias against lesbian, gay, bisexual, and transgender (LGBT) people still exists. In this Commentary, the author briefly reviews disparities with regard to LGBT health, in both health care and medical education, and discusses the implications of Burke and colleagues’ study of implicit and explicit biases against lesbian and gay people among heterosexual first-year medical students, published in this issue of Academic Medicine. Emphasis is placed on the ways in which physicians’ implicit bias against LGBT people can create a cycle that perpetuates a professional climate reinforcing the bias. The hidden curriculum in academic health centers is discussed as both a cause of this cycle and as a starting point for a research and intervention agenda. The findings from Burke and colleagues’ study, as well as other evidence, support raising awareness of LGBT discrimination, increasing exposure to LGBT individuals as colleagues and role models in academic health centers, and modifying medical education curricula as methods to break the cycle of implicit bias in medicine.

    ABSTRACT An outbreak of the fungal pathogen Cryptococcus gattii began in the Pacific Northwest (PNW) in the late 1990s. This outbreak consists of three clonal subpopulations: VGIIa/major, VGIIb/minor, and VGIIc/novel. Both VGIIa and VGIIc are unique to the PNW and exhibit increased virulence. In this study, we sequenced the genomes of isolates from these three groups, as well as global isolates, and analyzed a total of 53 isolates. We found that VGIIa/b/c populations show evidence of clonal expansion in the PNW. Whole-genome sequencing provided evidence that VGIIb originated in Australia, while VGIIa may have originated in South America, and these were likely independently introduced. Additionally, the VGIIa outbreak lineage may have arisen from a less virulent clade that contained a mutation in the MSH2 ortholog, but this appears to have reverted in the VGIIa outbreak strains, suggesting that a transient mutator phenotype may have contributed to adaptation and evolution of virulence in the PNW outbreak. PNW outbreak isolates share genomic islands, both between the clonal lineages and with global isolates, indicative of sexual recombination. This suggests that VGII C. gattii has undergone sexual reproduction, either bisexual or unisexual, in multiple locales contributing to the production of novel, virulent subtypes. We also found that the genomes of two basal VGII isolates from HIV+ patients contain an introgression tract spanning three genes. Introgression substantially contributed to intra-VGII polymorphism and likely occurred through sexual reproduction with VGI. More broadly, these findings illustrate how both microevolution and sexual reproduction play central roles in the development of infectious outbreaks from avirulent or less virulent progenitors.

    Recent syndemic models of sexual health disparities affecting racial/ethnic minorities have highlighted the role of discrimination. Yet no previous work has examined how acculturative stress (distress at the transition from one's original culture toward a new culture) associates with sexual HIV-risk behavior (SHRB). Work among other minority populations suggests sexual compulsivity (SC) may contribute to syndemic sexual health disparities as a means of coping with distress. With this in mind, the present study examined whether SC explained the relation between acculturative stress and SHRB. Separate analyses were conducted for males and females within a sample of 758 sexually initiated racial/ethnic minority college students. Among males and females, acculturative stress had an indirect effect on SHRB via SC. As the first study to examine SHRB in relation to acculturative stress, findings provide preliminary evidence that targeting SC among racial/ethnic minorities may help reduce sexual health disparities.

    Objectives This study aimed to detect ?- and ?-thalassaemia mutations in the Jino ethnic minority population of Yunnan Province, Southwest China. Design A total of 1613 Jino adults were continuously recruited from February 2012 to April 2012. Fasting venous blood samples were obtained to determine haematological variables. Haemoglobin analysis was conducted using high-performance liquid chromatography. Participants with hypochromic microcytic anaemia or positive haemoglobin analysis profiles were confirmed by ?- and ?-globin genetic testing, including DNA microarray analysis, direct sequencing methods and multiplex gap-PCR assays. Setting Shanghai Diabetes Institute, Shanghai Key Laboratory of Diabetes Mellitus, Shanghai Jiao Tong University Affiliated Sixth People's Hospital. Results We found 363 suspected cases by primary screening of haematological variables and haemoglobin analysis. After further genetic testing, four types of ?- and ?-thalassaemia mutation were detected in 203 out of 363 individuals. Both ?0- and ?+-thalassaemia mutations, --SEA and -?3.7, were identified. ?-Thalassaemia mutations included CD17 (HBB:c.52A>T) and CD26 (HbE or HBB:c.79G>A). In addition, 13 HbE carriers had coexisting ?0- or ?+-thalassaemia deletions. Clinical haematological variables indicated that, in this study, carriers of all thalassaemic genotypes had more severe hypochromic microcytic anaemia than non-thalassaemic individuals. Conclusions Our results provide information on the Jino ethnic minority that may be useful for further genetic counselling, prenatal screening and clinical diagnosis of thalassaemia in this region.

    Background Drug-resistant HIV are more prevalent and persist longer than previously demonstrated by bulk sequencing due to the ability to detect low-frequency variants. To clarify a clinical benefit to monitoring minority-level drug resistance populations as a guide to select active drugs for salvage therapy, we retrospectively analyzed the dynamics of low-frequency drug-resistant population in antiretroviral (ARV)-exposed drug resistant individuals. Materials and Methods Six HIV-infected individuals treated with ARV for more than five years were analyzed. These individuals had difficulty in controlling viremia, and treatment regimens were switched multiple times guided by standard drug resistance testing using bulk sequencing. To detect minority variant populations with drug resistance, we used a highly sensitive allele-specific PCR (AS-PCR) with detection thresholds of 0.32%. According to ARV used in these individuals, we focused on the following seven reverse transcriptase inhibitor-resistant mutations: M41L, K65R, K70R, K103N, Y181C, M184V, and T215F/Y. Results of AS-PCR were compared with bulk sequencing data for concordance and presence of additional mutations. To clarify the genetic relationship between low-frequency and high-frequency populations, AS-PCR amplicon sequences were compared with bulk sequences in phylogenetic analysis. Results The use of AS-PCR enabled detection of the drug-resistant mutations, M41L, K103N, Y181C, M184V and T215Y, present as low-frequency populations in five of the six individuals. These drug resistant variants persisted for several years without ARV pressure. Phylogenetic analysis indicated that pre-existing K103N and T215I variants had close genetic relationships with high-frequency K103N and T215I observed during treatment. Discussion and Conclusion Our results demonstrate the long-term persistence of drug-resistant viruses in the absence of drug pressure. The rapid virologic failures with pre-existing mutant viruses detectable by AS-PCR highlight the clinical importance of low-frequency drug-resistant viruses. Thus, our results highlight the usefulness of AS-PCR and support its expanded evaluation in ART clinical management. PMID:26360259

    1993-08-01

    Postcranial skeletal data from two recent Eskimo populations are used to test David Frayer's model of sexual dimorphism reduction in Europe between the Upper Paleolithic and Mesolithic. Frayer argued that a change from big-game hunting and adoption of new technology in the Mesolithic reduced selection for large body size in males and led to a reduction in skeletal sexual dimorphism. Though aspects of Frayer's work have been criticized in the literature, the association of big-game hunting and high sexual dimorphism is untested. This study employs univariate and multivariate analysis to test that association by examining sexual dimorphism of cranial and postcranial bones of two recent Alaskan Eskimo populations, one being big-game (whale and other large marine mammal) hunting people, and the second being salmon fishing, riverine people. While big-game hunting influences skeletal robusticity, it cannot be said to lead to greater sexual dimorphism generally. The two populations had different relative sexual dimorphism levels for different parts of the body. Notably, the big-game hunting (whaling) Eskimos had the lower multivariate dimorphism in the humerus, which could be expected to be the structure under greatest exertion by such hunting in males. While the exertions of the whale hunting economic activities led to high skeletal robusticity, as predicted by Frayer's model, this was true of the females as well as the males, resulting in low sexual dimorphism in some features. Females are half the sexual dimorphism equation, and they cannot be seen as constants in any model of economic behavior. PMID:8372937

    This study sought to compare the prevalence of, and relationship between, age at first experience of sexual violence and HIV and other health risk behaviors in two populations of men at high risk of HIV infection. Data were drawn from two cohorts: Vanguard, a prospective study of young men who have sex with men (MSM), and VIDUS, the Vancouver Injection Drug Users Study. Controlling for fixed sociodemographics, multivariate logistic regression was used to assess the relationship between age at first sexual violence (vs. never experiencing it) and several health risk behaviors. There were 140/498 (28%) MSM from Vanguard and 173/932 (19%) injection drug users (IDU) from VIDUS who reported having experienced sexual violence. Among VIDUS men, 130/852 (15%) IDU-only and 43/80 (54%) who were both IDU and MSM reported a history of sexual violence. The prevalence of child sexual abuse was 13% in Vanguard MSM, and 11% among VIDUS IDU-only, but 26% among VIDUS MSM/IDU. The median age of onset was significantly lower among VIDUS IDU-only compared to the two other groups. Experiencing sexual violence first in childhood was strongly related to ever being in the sex trade in both IDU and MSM. MSM in Vanguard who experienced sexual violence in childhood were more likely to have attempted suicide, and have a diagnosed mood disorder. Non-MSM IDU in VIDUS who experienced sexual violence in childhood were more likely to have a diagnosed mental illness, to binge on alcohol, and to have ever accidentally overdosed. In conclusion, men who have ever had sex with men appear to have a higher lifetime prevalence of sexual violence, compared to non-MSM injection drug users. Sexual violence is differentially associated with different health risk behaviors, depending on the age at first occurrence and the primary HIV risk factor (i.e. MSM vs. IDU). PMID:16971275

    The kinetic evolution in velocity space of a minority suprathermal electron population that is undergoing the anomalous Doppler instability (ADI) is investigated using the results from fully nonlinear numerical simulations that self-consistently evolve particles and fields in a plasma. Electron trajectories in phase space during different stages of the ADI are captured, and are analysed in relation to the characteristics of the excited electric fields and of the overall distribution of particles. For some electrons, trapping and mirroring effects are observed during the saturation phase. A relationship between the second order moments of the perpendicular electron distribution function and time is established, and is used to investigate the range of applicability of analytical approximations drawn from classical theory, that involve a quasilinear wave-driven diffusion operator.

    Introduction Provider-initiated HIV testing (PITC) is increasingly adopted in Europe. The success of the approach at identifying new HIV cases relies on its effectiveness at testing individuals most at risk. However, its suitability to reach populations facing overlapping vulnerabilities is under researched. This qualitative study examined HIV testing experiences and perceptions amongst Latin-American migrant men who have sex with men and transgender females in Spain, as well as health professionals’ experiences offering HIV tests to migrants in Barcelona and Madrid. Methods We conducted 32 in-depth interviews and 8 discussion groups with 38 Latin-American migrants and 21 health professionals. We imported verbatim transcripts and detailed field work notes into the qualitative software package Nvivo-10 and applied to all data a coding framework to examine systematically different HIV testing dimensions and modalities. The dimensions analysed were based on the World Health Organization “5 Cs” principles: Consent, Counselling, Connection to treatment, Correctness of results and Confidentiality. Results Health professionals reported that PITC was conceptually acceptable for them, although their perceived inability to adequately communicate HIV+ results and resulting bottle necks in the flow of care were recurrent concerns. Endorsement and adherence to the principles underpinning the rights-based response to HIV varied widely across health settings. The offer of an HIV test during routine consultations was generally appreciated by users as a way of avoiding the embarrassment of asking for it. Several participants deemed compulsory testing as acceptable on public health grounds. In spite of—and sometimes because of—partial endorsement of rights-based approaches, PITC was acceptable in a population with high levels of internalised stigma. Conclusion PITC is a promising approach to reach sexual minority migrants who hold high levels of internalised stigma but explicit extra efforts are needed to safeguard the rights of the most vulnerable.

    Puerto Rico has one of the highest incidence rates of HIV in the U.S. Concurrent with increases in sexually transmitted infections (STI), an increasing share of the new infections in PR are associated with sexual transmission. Much of the available research on sexual risk in PR derives from STI/HIV surveillance data. There is limited social and epidemiological research on sexual risk in PR, particularly in hidden and often hard-to-reach populations at high risk. Despite the absence of substantial resources that most epidemiological studies require, a research collaboration was initiated in 2007 between researchers in the School of Public Health at the University of Puerto Rico and the Centro Latinoamericano de Enfermedades de Transmisin Sexual (CLETS), one of the largest publicly funded centers for STI/HIV screening and treatment in the San Juan metropolitan area. Structured as a case study in the development of community-based research collaborations, this paper describes the early history and development of the project, including formative research, recruitment and training of students, and evolution in the study design that contributed to the current configuration of the ongoing "Core" study. Preliminary data are presented, highlighting data from a number of subpopulations that may contribute to our understanding of the role of behavioral risk in the STI/HIV epidemics in PR. More generally, the paper may guide the development of similar collaboration elsewhere in the Caribbean where HIV risk is increasing but where resources for research in high risk settings and groups are scarce.

    Sexual conflicts and their evolutionary outcomes may be influenced by population-specific features such as mating system and ecological context; however, very few studies have investigated the link between sexual conflict and mating system. The self-compatible, mixed-mating hermaphrodite Collinsia heterophylla (Plantaginaceae) is thought to exhibit a sexual conflict over timing of stigma receptivity. This conflict involves (i) delayed stigma receptivity, which intensifies pollen competition, and (ii) early fertilization forced by pollen, which reduces seed set. We investigated the potential for the conflict to occur under field conditions and performed glasshouse crosses within eight populations to assess its consistency across populations. Flowers were visited, and produced seeds after pollination, at all developmental stages, suggesting that the conflict can be of significance under natural conditions. In the glasshouse, early pollination imposed costs in all populations. Overall, the timing of first seed set was most strongly affected by the maternal parent, denoting stronger female than male ability to influence the onset of stigma receptivity. Crosses also revealed a negative relationship between donor- and recipient-related onset of receptivity within individuals, a novel result hinting at trade-offs in sex allocation or a history of antagonistic selection. Neither timing of stigma receptivity, timing of first seed set, nor pollen competitive ability covaried with population outcrossing rate. In conclusion, these results indicate that sexually antagonistic selection may be present in varying degrees in different populations of C. heterophylla, but this variation does not appear to be directly related to mating system variation.

    Objectives. We sought to determine whether health care use and expenditures among gay and bisexual men were reduced following the enactment of same-sex marriage laws in Massachusetts in 2003. Methods. We used quasi-experimental, prospective data from 1211 sexual minority male patients in a community-based health center in Massachusetts. Results. In the 12 months after the legalization of same-sex marriage, sexual minority men had a statistically significant decrease in medical care visits (mean = 5.00 vs mean = 4.67; P = .05; Cohen's d = 0.17), mental health care visits (mean = 24.72 vs mean = 22.20; P = .03; Cohen's d = 0.35), and mental health care costs (mean = $2442.28 vs mean = $2137.38; P = .01; Cohen's d = 0.41), compared with the 12 months before the law change. These effects were not modified by partnership status, indicating that the health effect of same-sex marriage laws was similar for partnered and nonpartnered men. Conclusions. Policies that confer protections to same-sex couples may be effective in reducing health care use and costs among sexual minority men. PMID:22390442

    In sexual conflict, aggressive males frequently diminish the long-term reproductive success of females in efforts to gain a short-term advantage over rival males. This short-term advantage can selectively favour high-exploitation males. However, just as the over-exploitation of resources can lead to local extinction, the over-exploitation of females in the form of harassment by aggressive males can yield similar consequences resulting in reduced female fecundity, increased female mortality and overall decline in mating activity. This outcome may often be prevented by selection acting at multiple levels of biological organization. Directional selection favouring aggressive exploitation within groups can be balanced by directional selection amongst groups opposing exploitation. Such between-group selection has recently been demonstrated in laboratory studies of water striders, where the conditional dispersal of individuals increased variation amongst groups and influenced the balance of selection toward reduced male aggression. This multilevel selection (MLS) framework also provides predictive value when investigating natural populations differing in their relative strength of selection within versus among groups. For water striders, the consequences of local exploitation cause fitness differences between groups, favouring less aggressive males. Inconsistently flowing ephemeral streams consist of isolated pools that prevent aggressive male water striders from escaping the consequences of local exploitation. We, therefore, predicted that inconsistently flowing ephemeral streams would favour the evolution of less aggressive males than would perennial streams, which allow aggressive males to move more freely and to escape the group-level costs of their aggression. Comparing two neighbouring streams during the mating season, we found that males dispersed naturally between pools at much higher rates in the perennial stream than in the ephemeral stream. As predicted, we found that males from the perennial stream were significantly more aggressive than those from the ephemeral stream. We also found that dispersers were significantly more aggressive than non-dispersers within each stream. These field results illustrate the relevance of the MLS framework in our understanding of the evolution of sexual conflict. PMID:24049189

  12. Population, sexual and reproductive health, rights and sustainable development: forging a common agenda.

    This article suggests that sexual and reproductive health and rights activists seeking to influence the post-2015 international development paradigm must work with sustainable development advocates concerned with a range of issues, including climate change, environmental issues, and food and water security, and that a way of building bridges with these communities is to demonstrate how sexual and reproductive health and rights are relevant for these issues. An understanding of population dynamics, including urbanization and migration, as well as population growth, can help to clarify these links. This article therefore suggests that whether or not sexual and reproductive health and rights activists can overcome resistance to discussing "population", become more knowledgeable about other sustainable development issues, and work with others in those fields to advance the global sustainable development agenda are crucial questions for the coming months. The article also contends that it is possible to care about population dynamics (including ageing and problems faced by countries with a high proportion of young people) and care about human rights at the same time. It expresses concern that, if sexual and reproductive health and rights advocates do not participate in the population dynamics discourse, the field will be left free for those for whom respecting and protecting rights may be less of a priority.

  13. Adiabatic theory for the population distribution in the evolutionary minority game

    Chen, Kan; Wang, Bing-Hong; Yuan, Baosheng

    2004-02-01

    We study the evolutionary minority game (EMG) using a statistical mechanics approach. We derive a theory for the steady-state population distribution of the agents. The theory is based on an adiabatic approximation in which short time fluctuations in the population distribution are integrated out to obtain an effective equation governing the steady-state distribution. We discover the mechanism for the transition from segregation (into opposing groups) to clustering (towards cautious behaviors). The transition is determined by two generic factors: the market impact (of the agents own actions) and the short time market inefficiency (arbitrage opportunities) due to fluctuations in the numbers of agents using opposite strategies. A large market impact favors extreme players who choose fixed opposite strategies, while large market inefficiency favors cautious players. The transition depends on the number of agents (N) and the effective rate of strategy switching. When N is small, the market impact is relatively large; this favors the extreme behaviors. Frequent strategy switching, on the other hand, leads to a clustering of the cautious agents.

  15. Sexual selection and temporal phenotypic variation in a damselfly population.

    2011-07-01

    Temporal variation in selection can be generated by temporal variation in either the fitness surface or phenotypic distributions around a static fitness surface, or both concurrently. Here, we use within- and between-generation sampling of fitness surfaces and phenotypic distributions over 2 years to investigate the causes of temporal variation in the form of sexual selection on body size in the damselfly Enallagma aspersum. Within a year, when the average female body size differed substantially from the average male body size, male body size experienced directional selection. In contrast, when male and female size distributions overlapped, male body size experienced stabilizing selection when variances in body size were large, but no appreciable selection when the variances in body size were small. The causes of temporal variation in the form of selection can only be inferred by accounting for changes in both the fitness surface and changes in the distribution of phenotypes. PMID:21569154

  16. Sexual recombination punctuated by outbreaks and clonal expansions predicts Toxoplasma gondii population genetics

    Grigg, Michael E.; Sundar, Natarajan

    2009-01-01

    The cosmopolitan parasitic pathogen Toxoplasma gondii is capable of infecting essentially any warm-blooded vertebrate worldwide, including most birds and mammals, and establishes chronic infections in one-third of the globe’s human population. The success of this highly prevalent zoonosis is largely the result of its ability to propagate both sexually and clonally. Frequent genetic exchanges via sexual recombination among extant parasite lineages that mix in the definitive felid host produces new lines that emerge to expand the parasite’s host range and cause outbreaks. Highly successful lines spread clonally via carnivorism and in some cases sweep to pandemic levels. The extent to which sexual reproduction versus clonal expansion shapes Toxoplasma’s current, global population genetic structure is the central question this review will attempt to answer.

    Researchers have noted increasingly the public health importance of addressing discriminatory policies towards lesbian, gay, and bisexual (LGB) populations. At present, however, we know little about the mechanisms through which policies affect LGB populations’ psychological well-being; in other words, how do policies get under our skin? Using data from a study of sexual minority young men (N = 1,487; M = 20.80 (SD = 1.93); 65% White; 92% gay), we examined whether statewide bans (e.g., same-sex marriage, adoption) moderated the relationship between fatherhood aspirations and psychological well-being. Fatherhood aspirations were associated with lower depressive symptoms and higher self-esteem scores among participants living in states without discriminatory policies. In states with marriage equality bans, fatherhood aspirations were associated with higher depressive symptoms and lower self-esteem scores, respectively. Fatherhood aspirations were associated negatively with self-esteem in states banning same-sex and second parent adoptions, respectively. Our findings underscore the importance of recognizing how anti-equality LGB policies may influence the psychosocial development of sexual minority men. PMID:24233971

  6. Evolutionary rescue of sexual and asexual populations in a deteriorating environment.

    2012-11-01

    The environmental change experienced by many contemporary populations of organisms poses a serious risk to their survival. From the theory of evolutionary rescue, we predict that the combination of sex and genetic diversity should increase the probability of survival by increasing variation and thereby the probability of generating a type that can tolerate the stressful environment. We tested this prediction by comparing experimental populations of Chlamydomonas reinhardtii that differ in sexuality and in the initial amount of genetic diversity. The lines were serially propagated in an environment where the level of stress caused by salt increased over time from fresh water to the limits of marine conditions. In the long term, the combination of high diversity and obligate sexuality was most effective in supporting evolutionary rescue. Most of the adaptation to high-salt environments in the obligate sexual-high diversity lines had occurred by midway through the experiment, indicating that positive genetic correlations of adaptation to lethal stress with adaptation to sublethal stress greatly increased the probability of evolutionary rescue. The evolutionary rescue events observed in this study provide evidence that major shifts in ways of life can arise within short time frames through the action of natural selection in sexual populations.

  8. Evolution of Population with Sexual and Asexual Reproduction in Changing Environment

    NASA Astrophysics Data System (ADS)

    He, Mingfeng; Yu, Changliang; Ruan, Hongbo; Yao, Lei

    Using a lattice model based on Monte Carlo simulations, we study the role of the reproduction pattern on the fate of an evolving population. Each individual is under the selection pressure from the environment and random mutations. The habitat ("climate") is changing periodically. Evolutions of populations following two reproduction patterns are compared, asexual and sexual. We show, via Monte Carlo simulations, that sexual reproduction by keeping more diversified populations gives them better chances to adapt themselves to the changing environment. However, in order to obtain a greater chance to mate, the birth rate should be high. In the case of low birth rate and high mutation probability there is a preference for the asexual reproduction.

    According to reinforcement theory, sexual isolation between species in sympatry is strengthened by natural selection against maladaptive hybrids. Drosophila pseudoobscura and D. persimilis from four locations where these species are sympatric, and from three locations where only D. pseudoobscura has been found, were utilized in studies of sexual isolation. Multiple-choice observation chambers were used to record matings between sympatric and allopatric strains of the two species. There was a wide variation in sexual isolation between the two species in the four localities we studied. The average isolation index for sympatric strains of the species was not significantly different from the average index for allopatric strains. There were no meaningful differences between the isolation indices in sympatric and allopatric strains of the species. The failure to find a relationship is likely the result of gene flow among populations within the two species. PMID:15864445

    Summary Background Increased sexual risk behaviour and HIV prevalence have been reported in migrants compared with non-migrants in sub-Saharan Africa. We investigated the association of residential and migration patterns with sexual HIV risk behaviours and HIV prevalence in an open, general population cohort in rural KwaZulu-Natal, South Africa. Methods In a mainly rural demographic surveillance area in northern KwaZulu-Natal, South Africa, we collected longitudinal demographic, migration, sexual behaviour, and HIV status data through household surveillance twice per year and individual surveillance once per year. All resident household members and a sample of non-resident household members (stratified by sex and migration patterns) were eligible for participation. Participants reported sexual risk behaviours, including data for multiple, concurrent, and casual sexual partners and condom use, and gave a dried blood spot sample via fingerprick for HIV testing. We investigated population-level differences in sexual HIV risk behaviours and HIV prevalence with respect to migration indicators using logistic regression models. Findings Between Jan 1, 2005, and Dec 31, 2011, the total eligible population at each surveillance round ranged between 21?129 and 22?726 women (aged 1749 years) and between 20?399 and 22?100 men (aged 1754 years). The number of eligible residents in any round ranged from 24?395 to 26?664 and the number of eligible non-residents ranged from 17?002 to 18?891 between rounds. The stratified sample of non-residents included between 2350 and 3366 individuals each year. Sexual risk behaviours were significantly more common in non-residents than in residents for both men and women. Estimated differences in sexual risk behaviours, but not HIV prevalence, varied between the migration indicators: recent migration, mobility, and migration type. HIV prevalence was significantly increased in current residents with a recent history of migration compared with other residents in the study area in men (adjusted odds ratio 119, 95% CI 107133) and in women (118, 110126). Interpretation Local information about migrants and highly mobile individuals could help to target intervention strategies that are based on the identification of transmission hotspots.

    Although sexual minority (SM) youth are at an increased risk for being bullied and experiencing depression, it is unclear how caregiver support is interrelated with those variables. Therefore, we sought to assess: (a) the prevalence of nonphysical bullying, depressive symptomatology, and caregiver support among heterosexual and SM girls, (b) the association between caregiver support and bullying in both groups, and (c) whether sexual orientation moderates the interactive effect of caregiver support and bullying on depressive symptoms. Data come from a survey of students in 22 Boston public high schools; 99 of the 832 girls in the analytic sample were SM. We used chi-square statistics to examine group differences, and multiple regression to estimate the association between the caregiver support, sexual orientation, being bullied, and depressive symptomatology. SM girls reported similar levels of caregiver support as heterosexual girls, but reported higher levels of depressive symptomatology. They were also more likely to report nonphysical bullying. Tests for interactions were not statistically significant, suggesting that bullying, caregiver support, and sexual orientation are independently associated with depressive symptomatology.

    This article seeks to analyze the association between sexual violence, manic and depressive episodes, and suicide risk among young adults. This is a cross-sectional population-based study carried out with young people between 18 and 24 years of age in a town in southern Brazil. The sample was selected through clusters. The prevalence of sexual violence, manic, depressive and mixed episodes and suicide risk were evaluated, as well as the association between them. The chi-square test and Poisson regression were used for statistical analysis. The study sample comprised 1,560 subjects. Among these, 3.1% had suffered sexual violence at some point in their life. The prevalence of depressive, mixed episodes, and (hypo)manic episodes were 10%, 2.4% and 2.3%, respectively. Suicide risk had a prevalence of 8.6% in the total sample. Young people who have suffered sexual violence are more likely to be subject to mood changes or suicide risk than those who have not (p < 0.05), except for the occurrence of (hypo)manic episodes. These results revealed a strong association between sexual violence and depressive and mixed episodes and suicide risk. PMID:26960097

    US demographic and sociopolitical shifts have resulted in a rapidly growing need for culturally competent neuropsychological services. However, clinical neuropsychology as a field has not kept pace with the needs of ethnic minority clients. In this discussion we review: historical precedents and the limits of universalism in neuropsychology; ethical/professional guidelines pertinent to neuropsychological practice with ethnic minority clients; critical cultural considerations in neuropsychology; current disparities germane to practice; and challenges to the provision of services to racial/ethnic minority clients. We provide a call to action for neuropsychologists and related organizations to advance multiculturalism and diversity within the field by increasing multicultural awareness and knowledge, multicultural education and training, multicultural neuropsychological research, and the provision of culturally competent neuropsychological services to racial/ethnic minority clients. Lastly, we discuss strategies for increasing the provision of culturally competent neuropsychological services, and offer several resources to meet these goals. PMID:20373222

We collected the data obtained by interviews in the period from 2005 to 2011 in the Voluntary Counseling and Testing Center for HIV/AIDS at the Institute of Public Health of Zadar County. Four hundred ninety four respondents were divided into risk and control groups. The majority of the respondents in our population does not consistently use condoms, in the risk group as much as 89.9%, and in the control group 65.7% of them (p< 0.001). Persons consuming alcohol when having sexual relations use condoms about 5x less often compared to those not consuming alcohol at all (OR=5.00; CI=1.69-14.29). There are significant differences among women and men in the risk group regarding reasons for non-use of condoms. The main reason with women is "I trust mypartners" 33.7% while men "do not like having sex with condoms, 53.6% of them (p < 0.001). The main risk factors for non-use of condoms are alcohol consumption at sexual relations, non-use of condoms in a casual relationship. Having in mind the non-use of condoms among populations of high-risk groups of acquiring HIV there are significant differences among genders. PMID:25507355

    2010-01-01

    Background With about 120 colour morphs currently assigned to six nominal species, the genus Tropheus is an ideal model to study evolutionary divergence of populations in allopatry. The morphology of Tropheus has been described as relatively static, but reproductive constraints are sexually dimorphic due to mouthbrooding in females. We analysed phenotypic variation in six populations of T. moorii and one population of T. polli using geometric morphometrics to assess morphological differences among sexes in relation to the differentiation of populations and species. Results The mean shapes differed significantly between sexes, populations, and species even though within-sex variation exceeded the divergence among populations. The first principal component of Procrustes shape coordinates revealed differences between populations and species in mouth position and ventral head shape. The second principal component reflected sex-specific shape differences, mainly comprising a relatively larger female viscerocranium and, in particular, a larger buccal area. While shape variation between populations and between sexes was primarily located in the cranial region, within-sex variation was relatively uniform across all landmarks. Conclusions Deviations of the between-population and between-sex pattern of shape variation from that within sex indicate that the differences in head shape likely result from both adaptations to female mouthbrooding and population-specific foraging strategies.

    Background/Significance High rates of HIV infection and other sexually transmitted infections (STIs) related to high risk sexual behaviors are a public health problem in the U.S. Hispanics have the second highest rates of HIV infection among racial/ethnic minorities. Previous research with Hispanic men has identified a number of factors that influence sexual risk and render Hispanic men at risk for HIV/STIs. These factors vary by sexual orientation. Despite these differences in sexual risk by sexual orientation, no study to date has compared the sexual behaviors of Hispanic men by sexual orientation. Objective The purpose of this study was to compare the sexual behaviors of a sample of Hispanic men by sexual orientation. Method A descriptive, cross-sectional design was used to collect data from 163 Hispanic men in South Florida, 80 heterosexual and 83 MSM. Participants completed measures of sexual health, sexual behaviors, and demographics. Results No statistically significant differences were found between the two groups of men in terms of age of sexual debut, number of sexual partners during the previous 3 months, condom usage during the previous 3 months, HIV testing history, and substance use during sex. Statistically significant differences were found between the two groups of men in terms of certain STIs. Implications Hispanic men as a population may engage in high risk sexual behaviors that place them at risk for HIV/STIs. More research is needed to develop both culturally tailored and sexual orientation appropriate interventions to assist Hispanic men reduce high risk sexual behaviors. PMID:25663832

  2. Evolutionary divergence in sexual signals: Insights from within and among barn swallow populations

    NASA Astrophysics Data System (ADS)

    Wilkins, Matthew Reed

    A wealth of studies across diverse animal groups indicate the importance of sexual selection in shaping phenotypes within and across breeding populations. In recent decades, much research has focused on how divergent sexual selection pressures among populations may lead to speciation. For my first dissertation chapter, I performed a literature review on the causes and consequences of evolutionary divergence in acoustic signals and developed the acoustic window conceptual framework for understanding the contributions of selection, genetic drift, and evolutionary constraint to signal divergence. Further, I found that sexual selection explains acoustic differences between recently diverged populations of the best-studied taxa. However, the relative contributions of ecological selection, sexual selection, and drift to acoustic divergence have not typically been considered within the same study systems. The remainder of my dissertation used the Northern Hemisphere-distributed barn swallow ( Hirundo rustica) species complex as a model system to study sender-receiver dynamics, intra- and intersexual selection pressures, and visual and acoustic signal interactions at the local scale, and signal divergence across populations at the global scale. From song recordings taken across 19 sampling sites, spanning five of six described subspecies, I demonstrated considerable conservation in song structure. However, temporal traits were highly divergent across subspecies, and in particular, the speed of the terminal trill of songs. In a detailed study of the multimodal communication system of the barn swallow (including visual and acoustic traits), I demonstrated that males and females use different types of signals to mediate competition and mate choice. One of the only exceptions to this rule was trill rate, which was also implicated in song divergence across populations. In order to test the function of trill rate in communication, I performed a two-year playback study within the North American subspecies, H. r. erythrogaster. Contrary to expectations, males did not have stronger responses to faster trilling (high performance) simulated intruders. Instead, resident males had stronger responses to the high performance stimulus only when the intruder was also darker than the resident. Collectively, my dissertation offers novel insight into the evolutionary dynamics of complex sexual signaling at multiple spatial scales.

    A present limitation of forensic anthropology practice in China is the lack of population-specific criteria on contemporary human skeletons. In this study, a sample of 203 maxillofacial Cone beam computed tomography (CBCT) images, including 96 male and 107 female cases (20-65 years old), was analyzed to explore mandible sexual dimorphism in a population of contemporary adult Han Chinese to investigate the potential use of the mandible as sex indicator. A three-dimensional image from mandible CBCT scans was reconstructed using the SimPlant Pro 11.40 software. Nine linear and two angular parameters were measured. Discriminant function analysis (DFA) and logistic regression analysis (LRA) were used to develop the mathematics models for sex determination. All of the linear measurements studied and one angular measurement were found to be sexually dimorphic, with the maximum mandibular length and bi-condylar breadth being the most dimorphic by univariate DFA and LRA respectively. The cross-validated sex allocation accuracies on multivariate were ranged from 84.2% (direct DFA), 83.5% (direct LRA), 83.3% (stepwise DFA) to 80.5% (stepwise LRA). In general, multivariate DFA yielded a higher accuracy and LRA obtained a lower sex bias, and therefore both DFA and LRA had their own advantages for sex determination by the mandible in this sample. These results suggest that the mandible expresses sexual dimorphism in the contemporary adult Han Chinese population, indicating an excellent sexual discriminatory ability. Cone beam computed tomography scanning can be used as alternative source for contemporary osteometric techniques. PMID:26146162

  4. Alleles versus genotypes: Genetic interactions and the dynamics of selection in sexual populations

    Physical interactions between amino-acids are essential for protein structure and activity, while protein-protein interactions and regulatory interactions are central to cellular function. As a consequence of these interactions, the combined effect of two mutations can differ from the sum of the individual effects of the mutations. This phenomenon of genetic interaction is known as epistasis. However, the importance of epistasis and its effects on evolutionary dynamics are poorly understood, especially in sexual populations where recombination breaks up existing combinations of alleles to produce new ones. Here, we present a computational model of selection dynamics involving many epistatic loci in a recombining population. We demonstrate that a large number of polymorphic interacting loci can, despite frequent recombination, exhibit cooperative behavior that locks alleles into favorable genotypes leading to a population consisting of a set of competing clones. As the recombination rate exceeds a certain critical value this ``genotype selection'' phase disappears in an abrupt transition giving way to ``allele selection'' - the phase where different loci are only weakly correlated as expected in sexually reproducing populations. Clustering of interacting sets of genes on a chromosome leads to the emergence of an intermediate regime, where localized blocks of cooperating alleles lock into genetic modules. Large populations attain highest fitness at a recombination rate just below critical, suggesting that natural selection might tune recombination rates to balance the beneficial aspect of exploration of genotype space with the breaking up of synergistic allele combinations.

    Demographic assessment of skeletal remains in forensic investigations includes identification of sex. The present study aimed to develop population-specific, sex-discriminating anthropometric standards for the mastoid triangle of a documented Saudi population using computed tomographic (CT) images of the lateral aspect of the skull. The present study was performed on 206 CT images of a documented Saudi population of known sex and age. The clinical CT images of subjects visiting the Department of Radiology, Dammam Medical Complex, Dammam, Saudi Arabia (KSA) were evaluated to know the validity of the metric assessment of the mastoid triangle for identification of sex in a Saudi population. The distance between asterion to porion (AP), asterion to mastoidale (AM), porion to mastoidale (PM) were measured and the area of the mastoid triangle (AMT) was calculated using these measurements. Discriminant function procedure was used to analyze the data for sexual dimorphism. In conclusion, the results of the present study indicate that all the 3 sides of the mastoid triangle and AMT were sexually dimorphic in the sampled Saudi population with PM being the best individual parameter in discriminating sex with an accuracy of 69.4%. Whereas, all the parameters combined showed the highest accuracy (71.4%). PMID:26165493

  6. Rapid evolution of a sexually selected trait following population establishment in a novel habitat.

    Colonization of novel environments creates new selection pressures. Sexually selected traits are affected by the physical and social environment and should be especially susceptible to change, but this has rarely been studied. In southern California, dark-eyed juncos, (Junco hyemalis) naturally breed in mixed-coniferous temperate forests, typically from 1500 m to 3000 m in elevation. In the early 1980s, a small population became established in a coastal habitat, the University of California, San Diego campus, which has a mild, Mediterranean climate. I show that a sexually and socially selected signaling trait--the amount of white in the tail--has declined by approximately 22% as compared to mountain juncos. I address three main factors that could explain the difference between mountain and coastal juncos: phenotypic plasticity, genetic drift, and selection. Results indicate that the first two can be ruled out as the sole cause of the plumage change, which implies that selection contributed to the genetic differentiation from the mountain population. The estimated rate of evolution is about 0.2 haldanes, comparable with rates of change in systems where individuals have been artificially introduced into new environments (e.g., guppies and Drosophila). This is the first study to demonstrate evolution of a sexually selected trait after only several generations resulting from a natural invasion into a novel environment. PMID:15058729

    Lesbian, gay, and bisexual populations are at elevated risk for tobacco use compared to their heterosexual peers. However, there is little research examining reasons for this disparity. Drawing on prior literature regarding psychosocial variables associated with both sexual orientation and smoking, the authors tested a path model of risk and protective factors to help explain sexual orientation differences in smoking using data from the Washington State Behavioral Risk Factor Surveillance System from 2003 to 2007. The authors estimated separate models for men and women, comparing lesbians or gays and bisexuals to heterosexuals. Results indicated that the explanatory variables accounted for most of the variance in this relationship, with both risk-enhancing and risk-reducing pathways. Mental health, life dissatisfaction, alcohol use, exposure to tobacco marketing, and single relationship status were risk enhancers for most LGB participants. Health-care access and income level were risk enhancers for bisexual participants only. Neither emotional support nor attitudes and knowledge about tobacco use helped explain the relationship between sexual orientation and smoking. These findings have significant implications for tobacco prevention and control efforts in this high-risk population. PMID:23039346

    OBJECTIVES: This study is part of a continuous evaluation of the Swiss AIDS prevention strategy from 1987 through 1994. METHODS: Annual telephone surveys of samples representative of the general population aged 17 through 45 years have been conducted since 1987 to monitor behavioral change. RESULTS: No major changes in level of sexual activity (lifetime number of partners, frequency of sexual encounters in the past week) or potential exposure to risk of HIV transmission (acquisition of a new steady partner during the year or of casual partners in the last 6 months) were observed. Systematic condom use with a new steady partner increased between 1988 and 1994, from 40% to 64% among 17- to 30-year-olds and from 57% to 72% among those aged 31 to 45. Systematic condom use with casual partners increased from 8% to 56% between 1987 and 1994 among 17- to 30-year-olds and from 22% to 42% between 1989 and 1994 among those aged 31 to 45. Condom use was higher among those with multiple partners. CONCLUSIONS: A general-population approach to AIDS prevention was able to achieve large-scale improvements in condom-based protection against HIV infection without inducing other major changes in sexual behavior.

    Context Adapting behavior change interventions to meet the needs of racial and ethnic minority populations has the potential to enhance their effectiveness in the target populations. But because there is little guidance on how best to undertake these adaptations, work in this field has proceeded without any firm foundations. In this article, we present our Tool Kit of Adaptation Approaches as a framework for policymakers, practitioners, and researchers interested in delivering behavior change interventions to ethnically diverse, underserved populations in the United Kingdom. Methods We undertook a mixed-method program of research on interventions for smoking cessation, increasing physical activity, and promoting healthy eating that had been adapted to improve salience and acceptability for African-, Chinese-, and South Asian–origin minority populations. This program included a systematic review (reported using PRISMA criteria), qualitative interviews, and a realist synthesis of data. Findings We compiled a richly informative data set of 161 publications and twenty-six interviews detailing the adaptation of behavior change interventions and the contexts in which they were undertaken. On the basis of these data, we developed our Tool Kit of Adaptation Approaches, which contains (1) a forty-six-item Typology of Adaptation Approaches; (2) a Pathway to Adaptation, which shows how to use the Typology to create a generic behavior change intervention; and (3) RESET, a decision tool that provides practical guidance on which adaptations to use in different contexts. Conclusions Our Tool Kit of Adaptation Approaches provides the first evidence-derived suite of materials to support the development, design, implementation, and reporting of health behavior change interventions for minority groups. The Tool Kit now needs prospective, empirical evaluation in a range of intervention and population settings. PMID:24320170

    Substantial changes in not only access to care, cost, and quality of care, but also health professions education are needed to ensure effective national healthcare reform. Since the actionable determinants of health such as personal beliefs and behaviors, socioeconomic factors, and the environment disproportionately affect the poor (and often racial/ethnic minorities), many have suggested that focusing efforts on this population will both directly and indirectly improve the overall health of the nation. Key to the success of such strategies are the ongoing efforts by historically black medical schools (HBMSs) as well as other minority serving medical and health professional schools, who produce a disproportionate percentage of the high-quality and diverse health professionals that are dedicated to maintaining the health of an increasingly diverse nation. Despite their public mission, HBMSs receive limited public support threatening their ability to not only meet the increasing minority health workforce needs but to even sustain their existing contributions. Substantial changes in health education policy and funding are needed to ensure HBMSs as well as other minority-serving medical and health professional schools can continue to produce the diverse, high-quality health professional workforce necessary to maintain the health of an increasingly diverse nation. We explore several model initiatives including focused partnerships with legislative and business leaders that are urgently needed to ensure the ability of HBMSs to maintain their legacy of providing compassionate, quality care to the communities in greatest need.

    Cultural differences between neighbouring populations are often said to give rise to reproductive barriers. For ethnic minorities, these barriers can easily result in genetic isolation. In this study, we analyse the surname structure of the Walser of the upper Lys Valley, a German-speaking ethnic minority in the Italian Western Alps, to better understand the relationships between linguistic and genetic isolation. Analyses were based on 1713 marriages registered from 1838 to 1938 in four villages of the valley: three Walser communities (Issime, Gressoney-Saint-Jean, Gressoney-La-Trinité) and the Romance community of Gaby. The results show that endogamy and inbreeding are lower than in other Italian linguistic minorities, with the exception of Gaby, whose values rank among the highest ever found in Italy. Compared to the Walser communities' Gaby behaves as an outgroup and has an almost exclusively autochthonous surname set. The latter aspect is also true, but to a lesser extent, for the Walser villages, in particular for Issime on the one hand and Gressoney-Saint-Jean and Gressoney-La-Trinité on the other. These findings strongly suggest that the Walser communities' ethnic minority status is not associated with genetic isolation, whereas genetic isolation was found in the linguistically non-isolated Gaby. Finally, our results are consistent with two independent late medieval migration events at the origin of these Walser settlements. PMID:21757790

    Many studies have shown that the finger length ratios might be characteristic for sexual dimorphism. The aim of the study was to determine sexual dimorphism in finger length ratios among the representatives of the Indo-Mauritian population. The study group comprised of 200 healthy Indo-Mauritian people (100 male and 100 female) of the age ranged from 19 to 25 years. The lengths of second (2D), third (3D), forth (4D) and fifth (5D) finger of both hands were measured by using a vernier caliper. Our results indicate that all finger length ratios have significant sex differences (p-value < 0.05) except 2D:5D and 3D:5D. To conclude, 2D:4D ratio is the most decisive ratio (predictive accuracy = 0.61) which can demarcate between male and female. PMID:26344459

    OBJECTIVE: To examine the characteristics of sexual assaults by strangers and those by people known to the victims in an urban community-based population of women. DESIGN: Descriptive study. SETTING: Sexual Assault Care Centre, Women's College Hospital, Toronto. PARTICIPANTS: All 677 women who presented to the centre between June 1, 1991, and Sept. 30, 1993, and for whom the victim-assailant relationship was known. OUTCOME MEASURES: Assailant's relationship to victim, sex of assailant, number of assailants, number, type and location of assaults, use of weapons, type of coercion and extent of physical trauma or injury. RESULTS: Sexual assault by a person known to the victim accounted for 456 (67.4%) of the assaults reported. In 344 cases the person was known more than 24 hours; 99 (28.8%) were current or previous boyfriends or spouses. Assailants who were strangers were more likely to assault the victim more than once (t = -2.42, 355 degrees of freedom [df], p < 0.05), force the victim to perform fellatio (chi 2 = 8.63, 1 df, p < 0.005), use weapons (chi 2 = 12.01, 1 df, p < 0.001) and use physical coercion (chi 2 = 4.42, 1 df, p < 0.05), whereas assailants who were known to the victims were more likely to assault a woman who was sleeping or drugged (chi 2 = 10.38, 1 df, p < 0.005). Sexual assault by a known assailant was more likely to occur in the home of the victim (chi 2 = 36.27, 1 df, p < 0.001) or the assailant (chi 2 = 8.46, 1 df, p < 0.005), whereas sexual assault by a stranger was more likely to occur outdoors (chi 2 = 89.80, 1 df, p < 0.001) or in a vehicle (chi 2 = 32.81, 1 df, p < 0.001). Overall, the mean number of trauma sites was greater among victims assaulted by strangers than among those assaulted by people they knew (t = -4.29, 180 df, p < 0.001). CONCLUSION: Two thirds of the sexual assaults in this urban population were committed by people known to the victims, and over two thirds of these assaults were associated with physical trauma. Improved victim services and prevention strategies should be built on this knowledge. PMID:7553516

    We investigated the genetic architecture of courtship song and cuticular hydrocarbon traits in two phygenetically distinct populations of Drosophila montana. To study natural variation in these two important traits, we analysed within-population crosses among individuals sampled from the wild. Hence, the genetic variation analysed should represent that available for natural and sexual selection to act upon. In contrast to previous between-population crosses in this species, no major quantitative trait loci (QTLs) were detected, perhaps because the between-population QTLs were due to fixed differences between the populations. Partitioning the trait variation to chromosomes suggested a broadly polygenic genetic architecture of within-population variation, although some chromosomes explained more variation in one population compared with the other. Studies of natural variation provide an important contrast to crosses between species or divergent lines, but our analysis highlights recent concerns that segregating variation within populations for important quantitative ecological traits may largely consist of small effect alleles, difficult to detect with studies of moderate power.

    Objective Minority populations in the United States are disproportionally affected by Human Papillomavirus (HPV) infection and HPV-related cancer. We sought to understand physician practices, knowledge and beliefs that affect utilization of the HPV vaccine in primary care settings serving large minority populations in areas with increased rates of HPV-related cancer. Study Design Cross-sectional survey of randomly selected primary care providers, including pediatricians, family practice physicians and internists, serving large minority populations in Brooklyn, N.Y. and in areas with higher than average cervical cancer rates. Results Of 156 physicians randomly selected, 121 eligible providers responded to the survey; 64% were pediatricians, 19% were internists and 17% were family practitioners. Thirty-four percent of respondents reported that they routinely offered HPV vaccine to their eligible patients. Seventy percent of physicians reported that the lack of preventive care visits for patients in the eligible age group limited their ability to recommend the HPV vaccine and 70% of those who reported this barrier do not routinely recommend HPV vaccine. The lack of time to educate parents about the HPV vaccine and cost of the vaccine to their patients were two commonly reported barriers that affected whether providers offered the vaccine. Conclusions Our study found that the majority of providers serving the highest risk populations for HPV infection and HPV-related cancers are not routinely recommending the HPV vaccine to their patients. Reasons for providers' failure to recommend the HPV vaccine routinely are identified and possible areas for targeted interventions to increase HPV vaccination rates are discussed. PMID:24886959

    The authors investigated the association between "heavy drinking" and sexual behaviors among 2,581 general population subjects from the St. Louis Epidemiologic Catchment Area survey conducted from 1981 to 1983. Lifetime sexual behaviors included promiscuity, infidelity, receiving money for sex, and same gender sex. It was found that sexual behaviors were associated with lifetime heavy drinking. Regardless of gender, race, or age, "heavy drinkers" were significantly more likely to report each of the high risk sexual behaviors, except same gender sex, compared to "nonheavy drinkers." With the multiple logistic regression analyses it was found that "heavy drinking" non-Black females, Black males regardless of drinking history, "heavy drinking" males, and younger subjects regardless of drinking history were at higher risk to report the high risk sexual behaviors. This study confirms that there is a strong association between "heavy drinking" and high risk sexual behaviors in a midwestern population. This is the first study to find an association between alcohol drinking patterns and high risk sexual behaviors in the general population. Implications of these findings for public health education efforts are discussed. PMID:8530215

    We measured the mean fitness of populations of Chlamydomonas reinhardtii maintained in the laboratory as obligately sexual or asexual populations for about 100 sexual cycles and about 1000 asexual generations. Sexuality (random gamete fusion followed by meiosis) is expected to reduce mutational load and increase mean fitness by combining deleterious mutations from different lines of descent. We found no evidence for this process of mutation clearance: the mean fitness of sexual populations did not exceed that of asexual populations, whether measured through competition or in pure culture. We found instead that sexual progeny suffer an immediate loss in fitness, and that sexual lines maintain genetic variance for fitness. We suggest that sexual populations at equilibrium with selection in a benign environment may be mixtures of several or many epistatic genotypes with nearly equal fitness. Recombination between these genotypes reduces mean fitness and creates genetic variance for fitness. This may provide fuel for continued selection should the environment change. PMID:17236420

    2014-12-01

    Through a comprehensive review of the literature on sexual assault, the authors propose to clarify the different stages of the exam and help the practitioner to the forensic interpretation of lesions. The authors describe the basic principles that make consensus in how to interview victims in order to increase the reliability of the information collected. The various medical data that must be collected allowing to guide diagnosis (urogenital symptoms, sexual behaviour disorder) or facilitate the interpretation of lesions (age of puberty, use of tampons) are specified as well as the different positions of examination and their association to other complementary techniques (Foley catheter, colposcopy, toluidine blue). The authors present a simple decision tree that can help the practitioner to interpret the laceration of the hymen. They detail the description and forensic interpretation of all genital lesions that may be encountered as a result of sexual assault, and the pitfalls to avoid. Finally, two main problems in the interpretation of lesions are described, the absence of injury after penetration and the accidental genital lesions. PMID:25458807

    Low-income populations, especially those belonging to minority groups, are among the most vulnerable groups before, during, and after a natural disaster. One of the factors that can be attributed to their vulnerability is the ineffectiveness of traditional risk communication systems in reaching this population. Many low-income populations are distrustful of government agencies and those who typically communicate risk messages. Consequently, traditional systems are not as effective in reaching these communities. Furthermore, traditional systems have been based on the social media that the general population uses and not based on social networks of disadvantaged populations which are more important than formal channels in these communities for dissemination of information. To bridge the gap, an approach is needed that relies on trusted agencies and leaders to educate and warn low-income communities about possible public health threats. A grassroots approach can enhance the capacity of the risk communication systems to more effectively reach vulnerable populations by engaging grassroots organizations in risk communication activities. The Guide to Enhance Grassroots Risk Communication Among Low-Income Populations provides strategies and guidance that can assist agencies in upgrading their systems for risk communication by building partnerships with local community stakeholders.

    Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013, 20 rare and diverse genotypes of P. infestans were detected in a region that centered around central New York State. The ratio of A1 to A2 mating types among these genotypes was close to the 50∶50 ratio expected for sexual recombination. These genotypes were diverse at the glucose-6-phosphate isomerase locus, differed in their microsatellite profiles, showed different banding patterns in a restriction fragment length polymorphism assay using a moderately repetitive and highly polymorphic probe (RG57), were polymorphic for four different nuclear genes and differed in their sensitivity to the systemic fungicide mefenoxam. The null hypothesis of linkage equilibrium was not rejected, which suggests the population could be sexual. These new genotypes were monomorphic in their mitochondrial haplotype that was the same as US-22. Through parentage exclusion testing using microsatellite data and sequences of four nuclear genes, recent dominant lineages US-8, US-11, US-23, and US-24 were excluded as possible parents for these genotypes. Further analyses indicated that US-22 could not be eliminated as a possible parent for 14 of the 20 genotypes. We conclude that US-22 could be a parent of some, but not all, of the new genotypes found in 2010 and 2011. There were at least two other parents for this population and the genotypic characteristics of the other parents were identified. PMID:25551215

    Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013, 20 rare and diverse genotypes of P. infestans were detected in a region that centered around central New York State. The ratio of A1 to A2 mating types among these genotypes was close to the 50?50 ratio expected for sexual recombination. These genotypes were diverse at the glucose-6-phosphate isomerase locus, differed in their microsatellite profiles, showed different banding patterns in a restriction fragment length polymorphism assay using a moderately repetitive and highly polymorphic probe (RG57), were polymorphic for four different nuclear genes and differed in their sensitivity to the systemic fungicide mefenoxam. The null hypothesis of linkage equilibrium was not rejected, which suggests the population could be sexual. These new genotypes were monomorphic in their mitochondrial haplotype that was the same as US-22. Through parentage exclusion testing using microsatellite data and sequences of four nuclear genes, recent dominant lineages US-8, US-11, US-23, and US-24 were excluded as possible parents for these genotypes. Further analyses indicated that US-22 could not be eliminated as a possible parent for 14 of the 20 genotypes. We conclude that US-22 could be a parent of some, but not all, of the new genotypes found in 2010 and 2011. There were at least two other parents for this population and the genotypic characteristics of the other parents were identified. PMID:25551215

    Context: Sex determination of skeletal remains forms part of archaeological and medicolegal examinations. It is an aspect of forensic odontology. Forensic odontology primarily deals with identification, based on recognition of unique features present in an individual's dental structures. Correct sex determination limits the pool of missing persons to just one half of the population. Aim of Study: Purpose of this study is to evaluate the existence of sexual dimorphism and variation in left and right maxillary first molars using bucco-lingual and mesio-distal dimensions in population of Sirmour District, H.P. Materials and Methods: Base sample comprised 100 subjects (50 males and 50 females) of an age group ranging from 17 to 25 years. Statistical Analysis Used: Unpaired t-test. Results: It was observed that the comparison of mean values of bucco-lingual and mesio-distal parameters showed highly statistically significant differences between males and females, measured both intraorally and on study casts. There were no significant differences between the mean values of both the parameters on the left side as compared to right side. Conclusion: The study concludes that sexual dimorphism is population specific. Among Himachali people, mesio-distal dimensions and bucco-lingual dimensions of first molar can aid in sex determination. PMID:26005295

    Revision of discriminant function formulae has always been advocated by anthropologist to take into account the changing pattern of sexual dimorphism due to temporal/secular changes. The present study aims to track temporal changes in cranial measurements of temporally distinct North Indian population and providing updated sex discriminating formulae. A total of 483 adult (20-65 years) crania representing contemporary and sub-recent populations collected from two medical colleges in North India. A total of 11 variables were measured to observe the changes in cranial dimension over time. Analysis of data demonstrated significant sexual and population (contemporary vs sub-recent sample) variations over time. The contemporary males and females exhibited larger cranial dimensions but it expressed less dimorphism than their predecessors. A trend toward brachycephalization was also observed in contemporary females. Maximum cranial length (84%) and biauricular breadth (79%) represent the most dimorphic variables for contemporary and sub-recent sample, respectively. The possible causes of such variations are discussed. PMID:25043554

    Concurrent sexual partnerships, or sexual partnerships that overlap in time, have been associated with HIV and sexually transmitted infections (STI). How best to measure concurrency and the personal characteristics and predictors of concurrency are not yet well understood. We compared two frequently used concurrency definitions, including a self-reported measure based on participant response regarding overlapping sex with partners, and the UNAIDS measure based on overlapping dates of last sex and intention to have sex again. We performed multivariable logistic regression analyses to identify socio-demographic, behavioral, and structural predictors of concurrency among 1,542 patients at an urban STI clinic in Jackson, Mississippi. Nearly half (44 %) reported concurrency based on self-reported sex with other partners, and 26 % reported concurrency according to the UNAIDS concurrency measure. Using the self-reported concurrency measure, the strongest predictors of concurrency were perceived partner concurrency, drug use at last sex, having more than 10 lifetime partners, and being recently incarcerated. Strongest predictors of concurrency using the UNAIDS measure were lifetime number of partners and perceived partner concurrency. Concurrency is highly prevalent in this population in the Deep South and social, structural and behavioral factors were important predictors of concurrency for both measures. Future research should use time anchored data collection methods and biomarkers to assess whether both definitions of concurrency are associated with HIV outcomes. PMID:24803130

    Several studies, notably from rural areas, have shown an association between mobility and HIV infection. However, reasons for this association are poorly documented. In this study, we examined the relationship between mobility, sexual behavior, and HIV infection in an urban population of Cameroon. A representative sample of 896 men and 1017 women were interviewed and tested for HIV infection and other sexually transmitted infections in Yaound in 1997. Mobile and nonmobile people were compared with respect to sociodemographic attributes, risk exposure, condom use, and prevalence of HIV infection, using descriptive statistics and multivariate logistic regression. Seventy-three percent of men and 68% of women reported at least 1 trip outside of Yaound in the preceding 12 months. Among men, the prevalence of HIV infection increased with time away from town. Men who declared no absence were 5 times less likely to be infected than were those away for >31 days (1.4% vs. 7.6%, respectively; adjusted odds ratio, 0.23; 95% confidence interval, 0.07-0.82). Furthermore, mobile men reported more risky sexual behaviors (ie, more partners and more one-off contacts). For women, the pattern was less clear: differences in the prevalence of HIV infection were less marked for nonmobile than for mobile women (6.9% vs. 9.8%, respectively; P > 0.1). This study suggests that characteristics of male mobility may be an important feature of the HIV epidemic in Cameroon. PMID:14707795

    Numerical simulations of minor mergers predict little enhancement in the global star formation activity. However, it is still unclear the impact they have on the chemical state of the whole galaxy and on the mass build-up in the galaxy bulge and disc. We present a two-dimensional analysis of NCG 3310, currently undergoing an intense starburst likely caused by a recent minor interaction, using data from the PPAK Integral Field Spectroscopy Nearby Galaxies Survey (PINGS). With data from a large sample of about a hundred H II regions identified throughout the disc and spiral arms, we derive, using strong-line metallicity indicators and direct derivations, a rather flat gaseous abundance gradient. Thus, metal mixing processes occurred, as in observed galaxy interactions. Spectra from PINGS data and additional multiwavelength imaging were used to perform a spectral energy distribution fitting to the stellar emission and a photoionization modelling of the nebulae. The ionizing stellar population is characterized by single populations with a narrow age range (2.5-5 Myr) and a broad range of masses (104-6 106 M?). The effect of dust grains in the nebulae is important, indicating that 25-70 per cent of the ultraviolet photons can be absorbed by dust. The ionizing stellar population within the H II regions represents typically a few per cent of the total stellar mass. This ratio, a proxy to the specific star formation rate, presents a flat or negative radial gradient. Therefore, minor interactions may indeed play an important role in the mass build-up of the bulge.

  16. Preferential sexual transmission of pseudorabies virus in feral swine populations may not account for observed seroprevalence in the USA

    PubMed Central

    Smith, Gary

    2013-01-01

    This paper compares the behavior of two competing models for the transmission of pseudorabies virus in feral swine in the USA. In first model, horizontal (non-sexual) density dependent transmission is the only transmission modality. In the second model, the only transmission modality is sexual transmission between mature males and females. The comparison of model behavior was carried out to test the hypothesis that preferential sexual transmission of PRV in feral swine can account for the seroprevalence observed in the field. The observed range of seroprevalence of PRV in mature feral swine in the USA is consistent with a preferential sexual transmission only if the feral swine mating system is a random mating system or a polygynous system in which there is a relatively large rate of acquisition of new mates. The observed range of seroprevalence of PRV in mature feral swine in the USA is not consistent with a preferential sexual transmission if there is mate guarding. This is important because the National Pseudorabies Surveillance Plan deems monitoring the risk of PRV introduction from feral swine to be a “minor objective” both in terms of the scope of the plan and with respect to the resources allocated. The rationale for this statement was derived from experimental studies, which suggested that the PRV indigenous to feral swine in the USA is preferentially sexually transmitted. PMID:21962753

    Recent debate has highlighted the importance of estimating both the strength of sexual selection on phenotypic traits, and the opportunity for sexual selection. We describe seasonal fluctuations in mating dynamics of Leptinotarsa undecimlineata (Coleoptera: Chrysomelidae). We compared several estimates of the opportunity for, and the strength of, sexual selection and male precopulatory competition over the reproductive season. First, using a null model, we suggest that the ratio between observed values of the opportunity for sexual selections and their expected value under random mating results in unbiased estimates of the actual nonrandom mating behavior of the population. Second, we found that estimates for the whole reproductive season often misrepresent the actual value at any given time period. Third, mating differentials on male size and mobility, frequency of male fighting and three estimates of the opportunity for sexual selection provide contrasting but complementary information. More intense sexual selection associated to male mobility, but not to male size, was observed in periods with high opportunity for sexual selection and high frequency of male fights. Fourth, based on parameters of spatial and temporal aggregation of female receptivity, we describe the mating system of L. undecimlineata as a scramble mating polygyny in which the opportunity for sexual selection varies widely throughout the season, but the strength of sexual selection on male size remains fairly weak, while male mobility inversely covaries with mating success. We suggest that different estimates for the opportunity for, and intensity of, sexual selection should be applied in order to discriminate how different behavioral and demographic factors shape the reproductive dynamic of populations.

    Objectives To investigate time trends in age at first heterosexual intercourse (FHI) and associated factors. Methods Data were collected from a national probability sample of the general population aged 18–49 years. Results Median age at FHI was 17 years for men and 18 years for women, but declined from 18 years to 17 years in men born after the early 1960s and in women born after the early 1970s. Early FHI (before age 16) was reported by 15.2% of men and 7.4% of women, but in recent cohorts (born 1975–82), proportions were similar in both sexes (16.9% and 14.4%, respectively). In women, higher educational level and acquiring most knowledge about sex from parents or in school were associated with later age at FHI. Half the women with early FHI judged the event to have occurred too soon. 4.2% of women with early FHI reported coercion at FHI, compared to 0.9% overall. The main factor associated with early FHI in men was not living with both parents up to the age of 15. Individuals with early FHI were more likely to report higher risk sexual behaviour as well as teenage motherhood and, for men, not having used a condom at FHI and bacterial sexually transmitted infections. Three in four individuals with early FHI thought they had inadequate sexual knowledge at FHI. Many would have liked to have learned more from parents and in school. Conclusions Improved sexual education among young Slovenians should aim to delay FHI until a more mature age and to be better prepared for safer sex. PMID:17151034

    In the literature that examines the distribution of environmental disamenities of various types, there is considerable documentation that minority groups and lower income groups are more likely to be exposed. Such differential exposure has been attributed to ``environmental racism`` by some authors, but there has been no systematic investigation of the factors and dynamics underlying this exposure pattern. This study examines regional differences in the proximity of African-American, Hispanics, Asians, and non-Hispanic Whites to a broad range facility types and explores the degree to which this may be related to urban and income factors.

  1. Intragenomic conflict in populations infected by Parthenogenesis Inducing Wolbachia ends with irreversible loss of sexual reproduction

    PubMed Central

    2010-01-01

    Background The maternally inherited, bacterial symbiont, parthenogenesis inducing (PI) Wolbachia, causes females in some haplodiploid insects to produce daughters from both fertilized and unfertilized eggs. The symbionts, with their maternal inheritance, benefit from inducing the production of exclusively daughters, however the optimal sex ratio for the nuclear genome is more male-biased. Here we examine through models how an infection with PI-Wolbachia in a previously uninfected population leads to a genomic conflict between PI-Wolbachia and the nuclear genome. In most natural populations infected with PI-Wolbachia the infection has gone to fixation and sexual reproduction is impossible, specifically because the females have lost their ability to fertilize eggs, even when mated with functional males. Results The PI Wolbachia infection by itself does not interfere with the fertilization process in infected eggs, fertilized infected eggs develop into biparental infected females. Because of the increasingly female-biased sex ratio in the population during a spreading PI-Wolbachia infection, sex allocation alleles in the host that cause the production of more sons are rapidly selected. In haplodiploid species a reduced fertilization rate leads to the production of more sons. Selection for the reduced fertilization rate leads to a spread of these alleles through both the infected and uninfected population, eventually resulting in the population becoming fixed for both the PI-Wolbachia infection and the reduced fertilization rate. Fertilization rate alleles that completely interfere with fertilization ("virginity alleles") will be selected over alleles that still allow for some fertilization. This drives the final resolution of the conflict: the irreversible loss of sexual reproduction and the complete dependence of the host on its symbiont. Conclusions This study shows that dependence among organisms can evolve rapidly due to the resolution of the conflicts between cytoplasmic and nuclear genes, and without requiring a mutualism between the partners.

    One of the most important factors that determine the evolutionary trajectory of a suite of traits in a population is the structure of the genetic variance-covariance matrix (G). We studied the cyclically parthenogenetic aphid Rhopalosiphum padi, whose populations exhibit two types of reproductive lineages respectively specialized in sexuality (that is, cyclically parthenogenetic lineages) and in asexuality (that is, obligate parthenogenetic lineages). We compared the quantitative genetics of life histories in these two lineage types. Our results suggest that both, the elements and the whole structure of the resulting G matrices differ in the very short term, between lineage types. This would involve the evolution toward different evolutionary optima in the same population, depending on whether sexual or asexual lineages predominate. Since sexual and asexual lineages vary seasonally in their abundance, a fluctuating selective regime has been proposed for this species, which would contribute to the maintenance of the reproductive polymorphism that these populations exhibit.

    Adult stem cells play an important role in maintaining tissue homeostasis. Although these cells are found in many tissues, the presence of stem cells in the human minor salivary glands is not well explored. Using the explant culture method, we isolated a population of cells with self-renewal and differentiation capacities harboring that reside in the human minor salivary glands, called human minor salivary gland mesenchymal stem cells (hMSGMSCs). These cells show embryonic stem cell and mesenchymal stem cell phenotypes. Our results demonstrate that hMSGMSCs have the potential to undergo mesodermal, ectodermal and endodermal differentiation in conditioned culture systems in vitro. Furthermore, in vivo transplantation of hMSGMSCs into SCID mice after partial hepatectomy shows that hMSGMSCs are able to survive and engraft, characterized by the survival of labeled cells and the expression of the hepatocyte markers AFP and KRT18. These data demonstrate the existence of hMSGMSCs and suggest their potential in cell therapy and regenerative medicine. PMID:26054627

    Aims and method To examine data on referrals to an inner-city London memory service to explore any differences in referral rates, cognitive assessments and stages of dementia at presentation between ethnic groups. Results AfricanCaribbean patients were well represented in the memory service. They were diagnosed with dementia on average 4.5 years younger than their White British counterparts and were more likely to be diagnosed with a vascular or mixed type dementia. However, scores on initial cognitive testing were significantly lower in the AfricanCaribbean group, possibly representing more advanced disease at presentation. Clinical implications Initiatives to access Black and minority ethnic populations earlier in the course of their illness should be considered. Professionals need to consider the potential for cultural bias in memory testing and diagnosing dementia in these populations, and the importance of cultural competency in assessments. PMID:26755947

    The Institute of Medicine highlighted the fact that the U.S. health care system does not provide consistent, high quality medical care to all people. The routine use of health information technology (HIT) that includes certain key functions may be critical in reducing such disparities. We used logistic regression analyses to examine differences when it comes to the routine use of key HIT functions that are linked to improvements in clinical care. Physicians predominantly serving Black patients were more likely than physicians predominantly serving White patients to routinely use HIT to generate reminders for clinicians and patients about preventive services. Similarly, physicians predominantly serving Hispanic patients were more likely than physicians predominantly serving White patients to routinely use HIT to access patients' preferred language. Importantly, although minority-serving institutions have lower adoption rates overall, differences exist in the routine use of key HIT functions that have the potential to reduce health disparities.

    Importance The use of a non-mydriatic camera for retinal imaging combined with the remote evaluation of images at a telemedicine reading center has been advanced as a strategy for diabetic retinopathy (DR) screening, particularly among patients with diabetes from minority populations with low eye care utilization. Objective To examine the rate and types of DR identified through a telemedicine screening program using a non-mydriatic camera, as well as the rate of other ocular findings. Design Cross-sectional. Setting Four urban clinic or pharmacy settings in the United States serving predominantly minority and uninsured persons with diabetes. Participants Persons age ? 18 years old who have type 1 or 2 diabetes and present to the community-based settings. Main Outcome Measure Percentage of DR detection including type of DR, and percentage of detection of other ocular findings. Results A total of 1,894 persons participated in the screening program across sites, with 21.7% having DR in at least one eye. The most common type of DR by far was background DR, which was present in 94.1% of all participants with DR. Almost half of those screened had ocular findings other than DR with 30% of other findings being cataract. Conclusions and Relevance In a DR telemedicine screening program in urban clinic/pharmacy settings in the US serving predominantly minority populations, 1 in 5 persons with diabetes screened positive for DR. The vast majority of DR was background indicating high public health potential for intervention in DRs earliest phases when treatment can prevent vision loss. Other ocular conditions were detected at a high rate, a collateral benefit of DR screening programs that may be under appreciated. PMID:25393129

    A long-standing belief in the literature on sex offenders is that sexually victimized youths are at increased risk of becoming sex offenders themselves. The present study tested the link between past sexual abuse, either with or without contact, and sexually offending behavior in a representative sample of male and female adolescents while controlling for other types of abuse, mental health problems, substance use, and non-sexual violent behaviors. Self-reported data were collected from a nationally representative sample of 6,628 students attending 9th grade public school in Switzerland (3,434 males, 3,194 females, mean age = 15.50 years, SD = 0.66 years). Exposure to contact and non-contact types of sexual abuse was assessed using the Child Sexual Abuse Questionnaire and sexually offending behavior by the presence of any of three behaviors indicating sexual coercion. Two-hundred-forty-five males (7.1 %) and 40 females (1.2 %) reported having sexually coerced another person. After controlling for non-sexual abuse, low parent education, urban versus rural living, mental health problems, substance use, and non-sexual violent behavior, male adolescents who were victims of contact sexual abuse and non-contact sexual abuse were significantly more likely to report coercive sexual behaviors. Females who experienced contact or non-contact sexual abuse were also found at increased risk of committing sexual coercion after controlling for covariates. The present findings demonstrate a strong relationship between past sexual abuse, with and without physical contact, and sexual-offending behavior in male and female adolescents. Reducing exposure to non-contact sexual abuse (like Internet-based sexual exploitation) should become a new area of sexual violence prevention in youths. PMID:25981223

    The identification of isolation signatures is fundamental to better understand the genetic structure of human populations and to test the relations between cultural factors and genetic variation. However, with current approaches, it is not possible to distinguish between the consequences of long-term isolation and the effects of reduced sample size, selection and differential gene flow. To overcome these limitations, we have integrated the analysis of classical genetic diversity measures with a bayesian method to estimate gene flow and have carried out simulations based on the coalescent. Combining these approaches, we first tested whether the relatively short history of cultural and geographical isolation of four "linguistic islands" of the Eastern Alps (Lessinia, Sauris, Sappada and Timau) had left detectable signatures in their genetic structure. We then compared our findings to previous studies of European population isolates. Finally, we explored the importance of demographic and cultural factors in shaping genetic diversity among the groups under study. A combination of small initial effective size and continued genetic isolation from surrounding populations seems to provide a coherent explanation for the diversity observed among Sauris, Sappada and Timau, which was found to be substantially greater than in other groups of European isolated populations. Simulations of micro-evolutionary scenarios indicate that ethnicity might have been important in increasing genetic diversity among these culturally related and spatially close populations.

However, with current approaches, it is not possible to distinguish between the consequences of long-term isolation and the effects of reduced sample size, selection and differential gene flow. To overcome these limitations, we have integrated the analysis of classical genetic diversity measures with a Bayesian method to estimate gene flow and have carried out simulations based on the coalescent. Combining these approaches, we first tested whether the relatively short history of cultural and geographical isolation of four “linguistic islands” of the Eastern Alps (Lessinia, Sauris, Sappada and Timau) had left detectable signatures in their genetic structure. We then compared our findings to previous studies of European population isolates. Finally, we explored the importance of demographic and cultural factors in shaping genetic diversity among the groups under study. A combination of small initial effective size and continued genetic isolation from surrounding populations seems to provide a coherent explanation for the diversity observed among Sauris, Sappada and Timau, which was found to be substantially greater than in other groups of European isolated populations. Simulations of micro-evolutionary scenarios indicate that ethnicity might have been important in increasing genetic diversity among these culturally related and spatially close populations.

    Debates about how coevolution of sexual traits and preferences might promote evolutionary diversification have permeated speciation research for over a century. Recent work demonstrates that the expression of such traits can be sensitive to variation in the social environment. Here, we examined social flexibility in a sexually selected male trait-cuticular hydrocarbon (CHC) profiles-in the field cricket Teleogryllus oceanicus and tested whether population genetic divergence predicts the extent or direction of social flexibility in allopatric populations. We manipulated male crickets' social environments during rearing and then characterized CHC profiles. CHC signatures varied considerably across populations and also in response to the social environment, but our prediction that increased social flexibility would be selected in more recently founded populations exposed to fluctuating demographic environments was unsupported. Furthermore, models examining the influence of drift and selection failed to support a role of sexual selection in driving population divergence in CHC profiles. Variation in social environments might alter the dynamics of sexual selection, but our results align with theoretical predictions that the role social flexibility plays in modulating evolutionary divergence depends critically on whether responses to variation in the social environment are homogeneous across populations, or whether gene by social environment interactions occur.

    Hispanics constitute the largest racial/ethnic minority population in the United States and are the fastest growing segment of the population. Knowledge about health needs and practices, effective health promotion programs, and health policy making for Hispanics has the potential to improve population health outcomes for this group. Continued research and practice literature will aid in accomplishing these objectives. However, little is known about the extent of health education-related literature available on Hispanic health issues. In this review, we analyzed research and practice publications in all health education-related journals to assess the volume of articles published on Hispanic health issues. We found that the portion of journal articles devoted to Hispanic health issues varied widely among the journals and that there was a very limited emphasis on Hispanic health-related issues. Journal editors and editorial board members may need to be more proactive in soliciting manuscripts on Hispanic health, and our practitioners may have to improve their professional skills and cultural competence in order to work with Hispanic populations to produce research and practice literature that is of adequate quantity and quality to help improve Hispanics' health.

    Background. Racial differences in blood group antigen distribution are common and may result in striking and interesting findings. These differences in blood group antigen distribution are important due to their influence on the clinical practice of transfusion medicine. Study Design and Methods. This is a prospective study, involving 1000 healthy regular repeat voluntary blood donors associated with the department. The clinically significant minor blood group antigens of these donors were studied. Results. Out of 1000 healthy regular repeat voluntary blood donors, 93% were D positive and 2.8% were K positive. Amongst the Rh antigens, e was the most common (99%), followed by D (93%), C (85.1%), c (62.3%), and E (21.5%). Within the MNS blood group system, antigen frequency was M (88%), N (57.5%), S (57.8%), and s (87.5%). Within the Duffy blood group system, antigen frequency was Fy(a) (87.3%) and Fy(b) (58.3%). Conclusions. This data base will help us to prevent alloimmunisation in young females, pregnant women, and patients who are expected to require repeated transfusions in life by providing them with antigen matched blood. Antigen negative blood can also be made available without delay to already alloimmunized multitransfused patients. PMID:24489547

  16. Species detection and identification in sexual organisms using population genetic theory and DNA sequences.

    Phylogenetic trees of DNA sequences of a group of specimens may include clades of two kinds: those produced by stochastic processes (random genetic drift) within a species, and clades that represent different species. The ratio of the mean pairwise sequence difference between a pair of clades (K) to the mean pairwise sequence difference within a clade (?) can be used to determine whether the clades are samples from different species (K/? ? 4) or the same species (K/?<4) with probability ? 0.95. Previously I applied this criterion to delimit species of asexual organisms. Here I use data from the literature to show how it can also be applied to delimit sexual species using four groups of sexual organisms as examples: ravens, spotted leopards, sea butterflies, and liverworts. Mitochondrial or chloroplast genes are used because these segregate earlier during speciation than most nuclear genes and hence detect earlier stages of speciation. In several cases the K/? ratio was greater than 4, confirming the original authors' intuition that the clades were sufficiently different to be assigned to different species. But the K/? ratio split each of two liverwort species into two evolutionary species, and showed that support for the distinction between the common and Chihuahuan raven species is weak. I also discuss some possible sources of error in using the K/? ratio; the most significant one would be cases where males migrate between different populations but females do not, making the use of maternally inherited organelle genes problematic. The K/? ratio must be used with some caution, like all other methods for species delimitation. Nevertheless, it is a simple theory-based quantitative method for using DNA sequences to make rigorous decisions about species delimitation in sexual as well as asexual eukaryotes. PMID:23308113

    OBJECTIVE--To compare common health experiences of a South Asian (predominantly Punjabi) population with that of the general population, according to sex, and to related patterns of health in the fourth decade of life to the pattern of hospital admission and mortality documented in the published reports. DESIGN AND SETTING--A cross sectional survey with interviews and physical measures was undertaken in a two stage stratified random cluster sample in the city of Glasgow. SAMPLE--This comprised 159 South Asians aged 30-40 years, mean age 35 (73.6% of those invited) and 319 subjects from the general population, all aged 35 years. MEASUREMENTS AND MAIN RESULTS--Body structure, lung function, pulse and blood pressure, history of physical and mental health, results of standardised questionnaires on mental health, angina and respiratory health, recent and past symptoms, history of accidents, and sickness behaviour were determined. South Asians were shorter, broader, and more overweight (women); they had lower values for forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), a faster pulse, and higher diastolic pressure (men). Fewer South Asians had had accidents or digestive symptoms (men); more had psychosomatic and high total symptoms (women); fewer wore glasses, had lost teeth, or had long standing illness (men) (all p < 0.01). Women had a lower FEV1/FVC ratio (p < 0.05). CONCLUSIONS--South Asians were consistently disadvantaged only in terms of anthropometric measures. Otherwise, the many differences were balanced, with disadvantage being concentrated only among South Asian women. The health gap between sexes in South Asians seems higher than in the general population. The findings show patterns of health in the fourth decade of life which are consistent with patterns of hospital admission and mortality documented in the published reports. PMID:8326280

    OBJECTIVES: This study examined the relationship between sexual orientation and suicide risk in a population-based sample of adolescents. METHODS: Participants were selected from a cross-sectional, statewide survey of junior and senior public high school students. All males (n = 212) and females (n = 182) who described themselves as bisexual/homosexual were compared with 336 gender-matched heterosexual respondents on three outcome measures: suicidal ideation, intent, and self-reported attempts. Logistic regression analyses were used to examine the association between sexual orientation and outcome measures with adjustment for demographic characteristics. RESULTS: Suicide attempts were reported by 28. 1 % of bisexual/homosexual males, 20.5% of bisexual/homosexual females, 14.5% of heterosexual females, and 4.2% of heterosexual males. For males, but not females, bisexual/homosexual orientation was associated with suicidal intent (odds ratio [OR] = 3.61 95% confidence interval [CI = 1.40, 9.36) and attempts (OR=7.10; 95% CI=3.05, 16.53). CONCLUSIONS: There is evidence of a strong association between suicide risk and bisexuality or homosexuality in males. PMID:9584034

  20. Can sexual selection theory inform genetic management of captive populations? A review

    Captive breeding for conservation purposes presents a serious practical challenge because several conflicting genetic processes (i.e., inbreeding depression, random genetic drift and genetic adaptation to captivity) need to be managed in concert to maximize captive population persistence and reintroduction success probability. Because current genetic management is often only partly successful in achieving these goals, it has been suggested that management insights may be found in sexual selection theory (in particular, female mate choice). We review the theoretical and empirical literature and consider how female mate choice might influence captive breeding in the context of current genetic guidelines for different sexual selection theories (i.e., direct benefits, good genes, compatible genes, sexy sons). We show that while mate choice shows promise as a tool in captive breeding under certain conditions, for most species, there is currently too little theoretical and empirical evidence to provide any clear guidelines that would guarantee positive fitness outcomes and avoid conflicts with other genetic goals. The application of female mate choice to captive breeding is in its infancy and requires a goal-oriented framework based on the needs of captive species management, so researchers can make honest assessments of the costs and benefits of such an approach, using simulations, model species and captive animal data.
