The association of sexual orientation measures with young adults' health-related outcomes

Cross-sectional associations of gender identity and sexual orientation, with co-occurrence and clustering of health-related behaviours among British adolescents: Millennium cohort study

PURPOSE

We examined whether gender identity and sexual orientation were associated with seven health-related behaviours, and with co-occurrence and clustering of these behaviours among British adolescents.

METHODS

Millennium Cohort Study (age 17 wave) provided data on the exposures, gender identity (male, female, genderqueer) and sexual orientation (heterosexual, bisexual, gay or lesbian, or other), and seven self-reported health-related behaviours (binge drinking, drug use, no consumption of breakfast, no consumption of fruits or vegetables, physical inactivity, poor sleep, and smoking or vaping). Poisson regressions examined associations between the exposures and single behaviours (reporting prevalence ratios (PRs)); and multinomial logistic regressions were used for behavioural cumulative co-occurrence score (reporting PRs). Cluster patterns were identified using Ward's agglomerative hierarchical cluster analysis while associations with cluster membership were performed using logistic regressions (reporting odds ratios (ORs)).

RESULTS

Our sample included 6022 adolescents (55.4% female, 1.5% genderqueer, 11.6% non-heterosexual). Adolescents who identified as genderqueer had the highest prevalence of not eating breakfast (PR: 60.5% [95%CI 48.4-71.4]) and poor sleep (68.7% [95%CI 55.6-79.3]). Those who identified as bisexual had a higher PR of co-occurring behaviours (2.46 [95%CI 1.39-4.27]). Among the three clusters identified (1: Multiple risk behaviours; 2: Physical inactivity and binge drinking; 3: Poor diet and physical inactivity), adolescents who identified as genderqueer or other sexual orientation showed the highest prevalence in cluster 3.

CONCLUSION

Gender and sexual minority British adolescents showed a higher prevalence of risky health-related behaviours, and higher risk of co-occurring behaviours. Physical inactivity and poor diet behaviours commonly clustered together for these groups.

Comparing asexual with heterosexual, bisexual, and gay/lesbian individuals in common mental health problems: A multivariate meta-analysis

We aimed to test whether asexual individuals were at increased risk of higher levels of depressive symptoms, self-harm attempts, and suicide attempts compared with heterosexual, bisexual, or gay/lesbian individuals using multivariate meta-analysis. Seventeen, five, and eight samples were included for depressive symptoms, self-harm attempts, and suicide attempts, respectively, reaching a total sample size of 125,675, 30,116, and 73,366, respectively. Asexual individuals reported higher levels of depressive symptoms than heterosexual individuals (Hedges' g = -0.44, 95%CI = [-0.61, -0.26]) but did not differ from heterosexual individuals in the risk of self-harm (odds ratio = 1.11, 95%CI = [0.88, 1.39]) and suicide attempts (odds ratio = 0.76, 95%CI = [0.56, 1.04]). Asexual individuals were at lower risk of self-harm and suicide attempts than bisexual and gay/lesbian individuals but did not differ from bisexual and gay/lesbian individuals in the levels of depressive symptoms. The greatest risk of higher levels of depressive symptoms was found in bisexual and asexual, followed by gay/lesbian individuals; the greatest risk of self-harm and suicide attempts was found in bisexual, followed by gay/lesbian individuals, and the lowest risk was found in asexual individuals. The magnitude of the disparities in the risk of poorer mental health among heterosexual, bisexual, gay/lesbian, and asexual individuals depended on the type of mental health outcomes.

Same-sex sexual behaviour and psychological health: CONSTANCES, a population survey in France

Rationale

Having same-sex partners is linked to poor psychological health and increased risk of suicide attempt. This link seems to be stronger for men than women. However, in France, there have been few studies of population samples, and the size of these studies does not always allow an in-depth analysis of these associations.

Methods and results

This study explored these associations by analysing data from a large epidemiological survey conducted in France from 2012 to 2019 that included 84,791 women and 75,530 men. The frequencies and risk ratios of depression, suicide attempts, alcohol dependence and regular cannabis use were calculated regarding two groups: those with only the other sex partners and those with any same sex partners. Risk of alcohol addiction and cannabis use was greatly increased for women who had homosexual relations, even after adjustment for social, demographic and sexual life factors, which was not the case for men. However, risk of depression and suicide attempts was increased for men who had homosexual relations; this was also true for women but to a lesser extent. The estimates remained unchanged after stratifying the population by three distinct social groups defined by education level.

Conclusions

The analysis of these differences was possible because of the large sample size of the CONSTANCES survey and its recruitment in the general population. This study helps increase knowledge of the health of sexual minorities. It can help clinicians pay more attention to the potential distress of their patients and can continue to inform policymakers of the effects of discrimination and stigmatisation linked to homosexual behaviour.

The Tsunamic Model of LGBTQ+ Deaths of Despair: A Systemic Review to Identify Risk Factors for Deaths of Despair Among LGBTQ+ People

The term Deaths of Despair (DOD) was introduced to capture the phenomenon of mortality associated with suicide, drug overdose, and alcoholic liver disease. The LGBTQ+ population consistently evidences disproportionately high rates of DOD. This study reviewed the literature on DOD within this community to create a conceptual model that identifies risk factors that work together to potentiate DOD in the LGBTQ+ community. Ten DOD-Related Factors were identified and used to create The Tsunamic Model of LGBTQ+ Deaths of Despair. DOD-Related Factors include: (1) Stigma, (2) Demographics, (3) Identity Development, (4) Internalized Homophobia, (5) Depression, (6) Victimization, (7) Isolation/Rejection, (8) Sensation Seeking, (9) Risky Behavior, and (10) Uninformed Care. Each factor is associated with increased risk for DOD among the LGBTQ+ community. This model can help health professionals by providing a framework for prevention and early intervention programs.

Sexual and Gender Minorities and Risk Behaviours among University Students in Italy

Sexual and gender minorities (SGM) may experience stigma, discrimination and show higher prevalence of behavioural risk factors than heterosexual counterparts. In Italy, the information on SGM is scarce and outdated. The present cross-sectional study aims to provide a more up-to-date estimate of the SGM proportion in young adults and to assess differences in the adoption of risk behaviours compared to their heterosexual counterparts. The study involved university students aged 18-25. Information on socio-demographic and behavioural characteristics were collected. The effect of sexual orientation on risk behaviours was assessed with a multinomial single-step logistic regression analysis. A total of 9988 participants were included. Overall, 518 students (5.2%) self-identified as SGM. While lesbians showed significantly higher odds of only non-regular use of protective barriers (AOR: 11.16), bisexuals showed higher odds for frequent drinking (AOR: 2.67), smoking (AOR: 1.85), multiple sexual partnerships (AOR: 1.78) and non-regular use of protective barriers (AOR: 1.90) compared with heterosexual women. Gay men showed higher odds of multiple sexual partnerships compared with heterosexual males (AOR: 5.52). SGM accounted for 5.2% of the sample, slightly more than the proportion found in the general population, but substantially in line with similarly aged populations abroad. Our findings confirm that unhealthy risk behaviours are more frequent among LGBTQ+, in particular among bisexual women. Rather than targeting specific subpopulations, our study aims to show the need for health promotion interventions that aim at the empowerment of all students regardless of sexual orientation, being aware that SGMs can benefit to a relatively greater extent.

Sexual orientation and health behaviors among college students in Italy

Studies regarding sexual orientation and health behaviors have largely neglected the Italian context. This research utilizes the second wave of the ‘Sexual and Emotional Life of Youths’ (SELFY) data set to compare the health behaviors of sexual minority (SM) and heterosexual college students in Italy. Results showed that bisexual women were more likely than heterosexual women to smoke both 1–7 and 8+ cigarettes per day, get drunk sometimes and often/very often, and use marijuana and/or ecstasy sometimes and often/very often. Homosexual women were more likely than heterosexual women to smoke 1–7 cigarettes per day, get drunk often/very often, and use marijuana and/or ecstasy often/very often. Homosexual men were more likely than heterosexual men to smoke 8+ cigarettes per day, but less likely to get drunk often/very often. Bisexual men were less likely than heterosexual men to participate in physical activity sometimes, often, and very often. Finally, bisexual men were less likely to exercise often than homosexual men. This work highlights that SM college students in Italy, particularly women, are more likely to engage in specific risky health behaviors compared to their heterosexual counterparts. More attention needs to be given to SMs in Italy to inform the Italian national health care system and to ensure that the appropriate care can be provided when required.

Sexual orientation and gender identity disparities in co-occurring depressive symptoms and probable substance use disorders in a national cohort of young adults

This study examined sexual orientation and gender identity differences in co-occurring depressive symptoms and substance use disorders (SUDs) among young adults in the Growing Up Today Study national cohort (n = 12,347; ages 20-35; 93% non-Hispanic white). Self-administered questionnaires assessed recent co-occurring depressive symptoms and probable nicotine dependence, alcohol use disorder, and drug use disorder. Multinomial logistic regressions with generalized estimating equations quantified differences in prevalences of depressive symptoms only, SUDs only, and co-occurrence, among sexual minorities (mostly heterosexual; lesbian, gay, and bisexual [LGB]) compared to completely heterosexual participants, and gender minorities compared to cisgender participants. Analyses stratified by sex assigned at birth revealed sexual minorities evidenced greater odds of co-occurrence than their completely heterosexual counterparts (assigned female AORs: 3.11-9.80, ps < 0.0001; assigned male AORs: 2.90-4.87, ps < 0.001). Sexual orientation differences in co-occurrence were pronounced among LGB participants assigned female at birth who evidenced nearly 10 times the odds of co-occurring depressive symptoms with nicotine dependence and drug use disorders than did heterosexual participants assigned female at birth. Relationships between gender identity and co-occurrence were generally weaker, possibly due to low power. Gender minorities assigned male at birth, however, evidenced greater odds of co-occurring depressive symptoms and alcohol use disorders (AOR 2.75, p = 0.013) than their cisgender counterparts. This study adds to the limited research quantifying sexual orientation or gender identity differences in recent co-occurring depressive symptoms and SUDs among young adults and suggests sexual and gender minority young adults should be prioritized in prevention and treatment of co-occurring depression and SUDs.

Sexual orientation and disordered eating in women: a meta-analysis

PURPOSE

Homosexuality is a clear risk factor for disordered eating in men; however, for women, research has yielded contradictory results. We conducted a meta-analysis to examine the association between sexual orientation and disordered eating in women.

METHODS

PRISMA guidelines were used. Studies comparing disordered eating between lesbians and heterosexual women were identified using PsycNet database and Google Scholar. Twenty-one studies met inclusion criteria. Overall disordered eating, restricting, binging and purging were examined for heterosexual, lesbian, bisexual and 'mostly heterosexual' women.

RESULTS

Whereas there was no significant difference in overall disordered eating between lesbians and heterosexual women, lesbians reported restricting less and binging more than heterosexual women. Bisexual women were more likely than lesbian women to restrict food intake and purge, and more likely than heterosexual women to have overall disordered eating and restrict food intake. "Mostly heterosexual" women were more likely than heterosexual women to restrict food intake, binge and purge.

CONCLUSIONS

Women of different sexual orientations show distinct patterns of disordered eating. Bisexual and "mostly heterosexual" women appear to be particularly at risk. Stress resulting from binegativity and rigid views of sexuality in a dichotomous society, rather than sexual orientation itself, may be associated with disordered eating in women. Findings should be viewed with caution because there were few studies with bisexual and "mostly heterosexual" women. This study elucidates the nature of the association between disordered eating and sexual orientation. Findings provide a possible explanation for previous inconsistencies, since opposing trends for different behaviors cancel each other out.

Sexual Minority-related Discrimination across the Life Course: Findings from a National Sample of Adults in the United States

In the United States, sexual minority (SM) status is associated with a number of health disparities. Based on mounting evidence, stigma and discrimination have been cited as key barriers to health equity for this population. We estimated the prevalence of three types of discrimination as a function of age among SM adults from the National Epidemiological Study of Alcohol Use and Related Conditions III (NESARC-III) (2012-2013). Among SM adults, reports of past-year general discrimination, victimization, and healthcare discrimination varied by age, with peaks in early adulthood and again in midlife. Age trends varied by biological sex, with males experiencing significantly more general discrimination, victimization, and healthcare discrimination at specific ages. Age trends also varied by sexual identity, as LGB-identifying SMs were significantly more likely to experience all forms of discrimination across all ages. Policies preventing homophobic discrimination and victimization are necessary given the pervasiveness of these experiences across adulthood.

Adolescent Sexual Behavior Patterns in a British Birth Cohort: A Latent Class Analysis

This study examined adolescent sexual behaviors patterns, and the consistency between sexual behavior and sexual orientation, in a prospective birth cohort. We used data on 5150 young people from the Avon Longitudinal Study of Parents and Children. Sexual orientation was assessed using a 5-point scale of sexual attraction at 15.5 years. Fourteen sexual activities were assessed using the Adolescent Sexual Activities Index at 13.5 and 15.5 years. Latent class analysis suggested four subgroups of adolescent sexual behaviors at 13.5: a "high-intensity sexual behaviors exclusively with other-sex, no same-sex intimacy" group (3.87%); a "moderate-intensity sexual behaviors exclusively with other-sex, no same-sex intimacy" group (16.57%); a "low-intensity sexual behaviors exclusively with other-sex, no same-sex intimacy" group (34.21%); and a "no sexual behavior" group (45.35%). There were five subgroups at 15.5 where four of them (23.42%, 18.37%, 28.12%, and 24.52%, respectively) were interpreted the same as at 13.5 years and a new "high-intensity sexual behaviors, some same-sex intimacy" subgroup (5.57%). Latent transition analysis showed approximately half the adolescents moved toward greater engagement in higher intensity sexual activities with other-sex at 15.5. Boys and girls who were in groups without same-sex intimacy were predominantly attracted to the other-sex, whereas there were moderate consistencies between same-sex intimacy and same-sex attraction for boys and low consistency for girls. Findings suggest that it may be important to include low-intensity sexual behaviors when assigning adolescents to sexual orientation groupings (via sexual behaviors) in order to reduce selection biases and increase statistical power via the increase in sample size.

Sexual fluidity and BMI, obesity, and physical activity

Analyzing reported changes in sexual identity over time is necessary for understanding young adult health risks. Utilizing waves 3 and 4 of the National Longitudinal Study of Adolescent to Adult Health, this paper studies the relationships between sexual identity changes and BMI, obesity, and physical activity among young adults in the U.S (N = 11,349). The results show that men who report a change toward a more homosexual identity have a significantly lower BMI and participate in more physical activity, while men who report a change toward a more heterosexual identity participate in less physical activity and have a higher BMI compared to those who did not report a change. For women, a change toward a more homosexual identity is significantly associated with more physical activity and lower odds of being obese compared to no change. The results suggest that specific sexual identity changes may also be linked to improvements in health.

•

Links between sexual fluidity and weight and physical activity are analyzed.

•

Certain sexual identity changes may improve weight and physical activity behavior.

•

The direction of sexual identity change matters more for men than for women.

Intimate Partner Violence Perpetration and Victimization Among Young Adult Sexual Minorities

CONTEXT

Intimate partner violence (IPV) among sexual minority young adults has been understudied, and victimization and perpetration estimates are needed.

METHODS

Data on 13,653 women and men aged 24-32 who participated in Wave 4 of the National Longitudinal Study of Adolescent to Adult Health were used to examine associations between sexual orientation and IPV perpetration and victimization in respondents' current or most recent relationship. Logistic regression analyses were used to identify associations between respondent characteristics and three IPV categories (physical violence, threatened violence and forced sex).

RESULTS

Some 94% of males and 80% of females identified as 100% heterosexual; 4% of males and 16% of females as mostly heterosexual; 1% of males and 2% of females as bisexual; and 2% of males and females as either mostly homosexual or 100% homosexual. Compared with their heterosexual counterparts, mostly heterosexual women were more likely to report having perpetrated or been a victim of physical IPV (odds ratios, 1.9 and 1.6, respectively), having threatened violence (2.0) and having been a victim of threatened violence and forced sex (1.6 for each); mostly heterosexual males were more likely to have been a perpetrator or victim of physical IPV (3.1 and 1.8, respectively) and a perpetrator of forced sex and threatened violence (2.0 and 1.8, respectively). Bisexual males had elevated odds of physical violence victimization (3.3) and forced sex victimization (4.9) and perpetration (5.0).

CONCLUSIONS

Some sexual minority groups are disproportionately affected by IPV, indicating a need for increased prevention efforts and for studies exploring the mechanisms underlying these differences.

Reconsidering Approaches to Estimating Health Disparities Across Multiple Measures of Sexual Orientation

Purpose: We propose a new theoretically grounded approach for estimating sexual orientation-related health risk that accounts for the unique and shared variance of sexual identity across other measures of sexual orientation (i.e., attraction and behavior). We argue and illustrate that this approach provides specificity not demonstrated by approaches that independently estimate and compare health risk based on sexual identity, attraction, and behavior. Methods: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions-III, collected in 2012-2013 (N = 36,309, ages 18 and older). The Karlson-Holm-Breen method tested the degree to which attraction- and behavior-based disparities in mental health and substance use disorders change after adjusting for sexual identity. Results: Sexual attraction- and behavior-based disparities in mental health and substance use disorders statistically varied when comparing models that did and did not adjust for sexual identity. Adjusting for sexual identity appeared to have a larger influence on attraction- and behavior-based health associations among men; sexual minority and majority differences were attenuated on nearly every outcome after adjusting for sexual identity. This attenuation was less common among women. Among women, some behavior-based disparities were wider in sexual identity-adjusted models relative to unadjusted models. Conclusion: We demonstrate more accurate approaches to capturing and comparing sexual orientation-related health disparities across multiple measures of sexual orientation, which account for the shared variance between sexual identity and measures of attraction and behavior. Adjusted estimates provide more specificity regarding relative health risk across specific subgroups of sexual minority people, and the intervention and prevention strategies needed to address them.

Psychiatric disorders, suicidality, and personality among young men by sexual orientation

Personality and its potential role in mediating risk of psychiatric disorders and suicidality are assessed by sexual orientation, using data collected among young Swiss men (n = 5875) recruited while presenting for mandatory military conscription. Mental health outcomes were analyzed by sexual attraction using logistic regression, controlling for five-factor model personality traits and socio-demographics. Homo/bisexual men demonstrated the highest scores for neuroticism-anxiety but the lowest for sociability and sensation seeking, with no differences for aggression-hostility. Among homo/bisexual men, 10.2% fulfilled diagnostic criteria for major depression in the past 2 weeks, 10.8% for ADHD in the past 12 months, 13.8% for lifetime anti-social personality disorder (ASPD), and 6.0% attempted suicide in the past 12 months. Upon adjusting (AOR) for personality traits, their odds ratios (OR) for major depression (OR = 4.78, 95% CI 2.81–8.14; AOR = 1.46, 95% CI 0.80–2.65) and ADHD (OR = 2.17, 95% CI = 1.31–3.58; AOR = 1.00, 95% CI 0.58–1.75) lost statistical significance, and the odds ratio for suicide attempt was halved (OR = 5.10, 95% CI 2.57–10.1; AOR = 2.42, 95% CI 1.16–5.02). There are noteworthy differences in personality traits by sexual orientation, and much of the increased mental morbidity appears to be accounted for by such underlying differences, with important implications for etiology and treatment.

Who I am: Reflections on a successful bisexual research method

Bisexual people have consistently been found to experience poorer mental health than their lesbian, gay and heterosexual counterparts and more research is urgently needed to shed greater light on the reasons behind this phenomenon. However, due to the paucity of such research, there is a severe limitation of methodological insights to inform future research. This article presents the methodological approach of the recent Who I Am study with a particular focus on the effective recruitment strategies that allowed the research team to overcome common barriers to recruitment with this population. The study utilised a cross-sectional survey method and, through the incorporation of an extensive recruitment strategy and comprehensive survey instrument, successfully recruited one of the largest samples of bisexual people to date ( n = 2,651). Sharing methodological successes and challenges in this field will prove valuable in informing much needed future research.

Illicit and Prescription Drug Misuse among Sexual Minority Women in the United States: A Protocol for a Scoping Review

BACKGROUND

The United States Institute of Medicine (IOM) published reports in 1999 and 2011 identifying drug use as a priority area for sexual minority health research, specifically focused on mechanisms contributing to drug use disparities and the development of tailored interventions. Limited research has prioritized sexual minority women (SMW) with the majority of substance use research among sexual minorities focused on adolescents and men who have sex with men. This scoping review will characterize the research literature related to illicit drug use and prescription drug misuse among SMW and sub-groups within the SMW population. Through this, we will identify: (1) specific substances used; (2) patterns of substance use; (3) risk and protective factors; (4) prevention interventions; and (5) drug treatment programs specific to SMW.

METHODS/DESIGN

This review will include studies with empirical data of illicit or prescription drug misuse among sexual minority women. Peer-reviewed quantitative research conducted in the United States and published in English from 2011-Present will be included. We will search Medline, PsycINFO, and Web of Science databases for relevant articles. Two independent reviewers will screen abstracts and relevant full-text studies for eligibility. Data will be extracted from eligible articles and results will be presented in narrative and tabular form as appropriate.

DISCUSSION

This work will identify gaps of knowledge in the research pertaining to illicit or prescription drug misuse among sexual minority women since the 2011 US IOM report. As a result of this work, we will propose directions for future research to address identified gaps.

Do inequalities add up? Intersectional inequalities in smoking by sexual orientation and education among U.S. adults

•

Among men, inequalities in cigarette smoking are primarily driven by socio-economic inequalities.

•

Among women, inequalities in cigarette smoking are primarily driven by sexual orientation inequalities.

Introduction

Inequalities in smoking by socio-economic status (SES) are well-known. A growing body of literature has demonstrated additional inequalities in smoking by sexual orientation. This study used an intersectional lens to examine smoking at the intersection of sexual orientation and education.

Methods

Data come from 28,362 adult participants in Wave 2 (2014–2015) of the Population Assessment of Tobacco and Health (PATH) Study. We used educational level (less than high school education (HS); HS or more) and sexual orientation (heterosexual; sexual minority) to form four intersectional positions.

We estimated prevalence differences in smoking corresponding to joint, referent, and excess intersectional inequalities using weighted linear binomial regression models. Results were stratified by gender and adjusted for ethnicity and age.

Results

The adjusted joint inequality represented 7.6% points (p.p.) (95% CI: 2.5, 12.8) difference in smoking between the doubly advantaged (heterosexual with HS or more) and doubly disadvantaged (sexual minority with less than HS) positions. Joint inequality was decomposed into referent SES inequality (12.5 p.p. (95% CI: 10.5, 14.4)); referent sexual orientation inequality (9.7 p.p. (95% CI: 6.8, 12.6)); and a substantial negative excess intersectional inequality (−14.6 p.p. (95% CI: −20.8, −8.3)), attributed to an unexpectedly low prevalence of smoking among doubly disadvantaged persons. Similar overall patterns were found in the stratified analyses.

Conclusions

We found that “doubly-disadvantaged” group of low-educated sexual minority adults did not have the greatest burden of smoking; whereas, low-educated heterosexual adults had the highest smoking prevalence. Our findings support tailoring cessation interventions to disadvantaged groups’ different needs.

Sexual Orientation Development of Heterosexual, Bisexual, Lesbian, and Gay Individuals: Questions and Hypotheses Based on Kaestle's (2019) Research

Christine Kaestle's work assessed the three major dimensions of sexual orientation: sexual attractions, behaviors, and identity. She tracked the unfolding of sexual orientation over time, from adolescence to early adulthood (i.e., late twenties to early thirties), using three waves of data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a U.S. representative sample. This article addresses some of the implications, questions, and hypotheses suggested by Kaestle's findings. It ends by requesting follow-up data in adulthood to test hypotheses and resolve differences between the author and Kaestle in interpretation of the data.

Sex × Gender and Sexual Orientation in Relation to Stress Hormones and Allostatic Load

In this selective review, emerging literature linking biological sex, sociocultural gender, and sexual orientation to stress hormone functioning and multisystemic physiological dysregulations are summarized. Beyond sex as a binary biological variable, continuums of sex hormones, gender roles, gender identity, and sexual orientation each uniquely help delineate pathways and mechanisms linked to stress-related disease trajectories. This implicates glucocorticoid functioning and allostatic load, the “wear and tear” of chronic stress in synergy with unhealthy behaviors. Clinical considerations are also discussed for the field of gender medicine.

Identifying Basic Classes of Sexual Orientation with Latent Profile Analysis: Developing the Multivariate Sexual Orientation Classification System

Despite considerable progress, research on sexual minorities has been hindered by a lack of clarity and consistency in defining sexual minority groups. Further, despite recent recommendations to assess the three main dimensions of sexual orientation-identity, behavior, and attraction-it remains unclear how best to integrate such multivariate information to define discrete sexual orientation groups, particularly when identity and behavior fail to match. The current study used a data-driven approach to identify a parsimonious set of sexual orientation classes. Latent profile analysis (LPA) was run within a large (N = 3182) and sexually diverse sample, using dimensions of sexual identity, behavior, and attraction as predictors. LPAs supported four fundamental sexual orientation classes not only in the overall sample, but also when conducted separately in men (n = 980) and women (n = 2175): heterosexual, homosexual, bisexual, and heteroflexible (a class representing individuals who self-identify as heterosexual or mostly heterosexual but report moderate same-sex sexual behavior and attraction). Heterosexuals reported the highest levels of psychological functioning and lowest risk behaviors. Homosexuals showed similarly high levels of psychological functioning to heterosexuals, but higher levels of risk behaviors. Bisexuals and heteroflexibles showed similarly low levels of psychological functioning and high risk taking. To facilitate applications of this classification approach, the study developed the Multivariate Sexual Orientation Classification System, reproducing the four LPA groups with 97% accuracy (kappa = .95) using just two items. Implications of this classification approach are discussed.

Sexual Identity and Behavior Among U.S. High School Students, 2005-2015

Sexual orientation is a multidimensional construct which is increasingly recognized as an important demographic characteristic in population health research. For this study, weighted Youth Risk Behavior Survey data were pooled across 47 jurisdictions biennially from 2005 to 2015, resulting in a national sample of 98 jurisdiction-years (344,815 students). Respondents were a median of 15.5 years, 49.9% male, and 48.8% White. Sexual identity and behavior trends from 2005 to 2015 were assessed with logistic regression analysis. Overall, 13.9% of females and 7.0% of males identified as lesbian, gay, bisexual (LGB), or not sure, while 9.1% of females and 4.2% of males indicated both same-and-different-sex behavior or same-sex behavior. In total, 17.0% of female and 8.5% of male youth reported non-heterosexual (LGB or not sure) sexual identity, same-sex sexual behavior, or both. LGB youth were approximately twice as likely as other youth to report lifetime sexual behavior. White and Asian youth were less likely to report non-heterosexual identity and/or have engaged in same-sex sexual behaviors than youth of other races/ethnicities. Prevalence of non-heterosexual identities increased over time for both sexes, but only female youth reported significantly more same-sex behavior over time. This is the first study to simultaneously assess adolescent sexual identity and behavior over time within a national dataset. These findings are critical for understanding the sexual health needs of adolescents and for informing sexual health policy and practice.

A Life History Approach to the Female Sexual Orientation Spectrum: Evolution, Development, Causal Mechanisms, and Health

Women's capacity for sexual fluidity is at least as interesting a phenomenon from the point of view of evolutionary biology and behavioral endocrinology as exclusively homosexual orientation. Evolutionary hypotheses for female nonheterosexuality have failed to fully account for the existence of these different categories of nonheterosexual women, while also overlooking broader data on the causal mechanisms, physiology, ontogeny, and phylogeny of female nonheterosexuality. We review the evolutionary-developmental origins of various phenotypes in the female sexual orientation spectrum using the synergistic approach of Tinbergen's four questions. We also present femme-specific and butch-specific hypotheses at proximate and ultimate levels of analysis. This review article indicates that various nonheterosexual female phenotypes emerge from and contribute to hormonally mediated fast life history strategies. Life history theory provides a biobehavioral explanatory framework for nonheterosexual women's masculinized body morphology, psychological dispositions, and their elevated likelihood of experiencing violence, substance use, obesity, teenage pregnancy, and lower general health. This pattern of life outcomes can create a feedback loop of environmental unpredictability and harshness which destabilizes intrauterine hormonal conditions in mothers, leading to a greater likelihood of fast life history strategies, global health problems, and nonheterosexual preferences in female offspring. We further explore the potential of female nonheterosexuality to function as an alloparental buffer that enables masculinizing alleles to execute their characteristic fast life history strategies as they appear in the female and the male phenotype. Synthesizing life history theory with the female sexual orientation spectrum enriches existing scientific knowledge on the evolutionary-developmental mechanisms of human sex differences.

Are sociodemographic, lifestyle, and psychosocial characteristics associated with sexual orientation group differences in mental health disparities? Results from a national population-based study

PURPOSE

Sexual minority mental health disparities are well documented. However, distinct sexual minority subgroups are often collapsed into a single "lesbian, gay, or bisexual" (LGB) analytic group. While limited research has shown sexual minority subgroup differences in mental health, little is known about the factors underlying these differences. This study examines whether sociodemographic, lifestyle, and psychosocial characteristics are associated with sexual orientation subgroup differences in mental health.

METHODS

Using the National Epidemiologic Survey on Alcohol and Related Conditions, Wave III, differences in various mental health measures, and sociodemographic, lifestyle, and psychosocial characteristics were assessed across three sexual minority subgroups [lesbians/gay men, bisexuals, and heterosexuals reporting same-sex attractions or behaviors ("heterosexual-identified sexual minorities, HSM")] and heterosexuals reporting only opposite-sex attractions and behaviors ("heterosexuals"). Sequential linear regressions evaluated the degrees to which different factors attenuated mental health (SF-12) disparities between heterosexuals and sexual minority subgroups. Analyses were sex-stratified.

RESULTS

Several sociodemographic, lifestyle, and psychosocial characteristic differences existed between sexual orientation groups. Further, all sexual minority subgroups had lower SF-12 scores than heterosexuals, except lesbian women. Sociodemographic factors attenuated the disparity for bisexual men. Sociodemographic, lifestyle, plus psychosocial factors attenuated the disparity for HSM men. However, sociodemographic, lifestyle, and psychosocial factors partially, but did not fully, attenuate the disparity for gay men, bisexual women, or HSM women.

CONCLUSIONS

Different factors are associated with mental health disparities for sexual minority subgroups. To maximize health intervention efforts, additional research is needed to uncover the specific mechanisms contributing to health disparities across diverse sexual minority populations.

Outcomes among pregnant recently incarcerated women attending a reentry transitions clinic

This mixed methods retrospective case series and qualitative descriptive study describes pregnancy outcomes during the postincarceration period. A retrospective case series via electronic medical record chart review from a subset of women attending a postincarceration primary care clinic with a condition of interest (pregnancy) described demographics, substance use, diagnoses, and pregnancy outcomes. We compared 27 pregnant to 79 nonpregnant women and contextualized quantitative data with qualitative descriptive vignettes. Twenty-seven women completed 29 pregnancies (2 women with 2 deliveries each), all of which were unplanned; there were 11 live births, 8 pregnant at study closure, 7 miscarriages, and 3 terminations. Although substance use history was high, rates were higher among nonpregnant women (92% vs 74%). Among the 5 births, 4 tested positive for substance use during pregnancy. All 11 infants had pregnancy or delivery complications. Although 7 of the 10 pregnant women with live births had prior pregnancy complications, only 4 were placed in a special care obstetrics clinic. Although unplanned pregnancies were common, most births did not demonstrate maternal substance use. All live births had pregnancy or delivery complications, but few were accepted to specialist prenatal care, suggesting potential considerations for recently incarcerated women.

Sexual Orientation: Categories or Continuum? Commentary on Bailey et al. (2016)

Bailey et al. (2016) have provided an excellent, state-of-the-art overview that is a major contribution to our understanding of sexual orientation. However, whereas Bailey and his coauthors have examined the physiological, behavioral, and self-report data of sexual orientation and see categories, I see a sexual and romantic continuum. After noting several objections concerning the limitations of the review and methodological shortcomings characteristic of sexual-orientation research in general, I present evidence from research investigating in-between sexualities to support an alternative, continuum-based perspective regarding the nature of sexual orientation for both women and men. A continuum conceptualization has potential implications for investigating the prevalence of nonheterosexuals, sexual-orientation differences in gender nonconformity, causes of sexual orientation, and political issues.

Sexual minority health disparities: an examination of age-related trends across adulthood in a national cross-sectional sample

PURPOSE

Sexual minorities experience significant health disparities across a variety of mental, behavioral, and physical health indicators. Yet, an understanding of the etiology and progression of sexual minority health disparities across the lifespan is limited.

METHODS

We used the U.S. National Epidemiologic Survey of Alcohol and Related Conditions III to evaluate the association between sexual minority status and seven past-year health outcomes (alcohol use disorder, tobacco use disorder, drug use disorder, major depressive episode, generalized anxiety disorder, sexually transmitted infection, and cardiovascular conditions). To do this, we used unadjusted and adjusted logistic regression among our study sample (n = 30,999; aged 18-65 years) and time-varying effect models to evaluate how sexual orientation differences in these outcomes vary across adulthood.

RESULTS

Relative to heterosexuals, sexual minorities had elevated odds of past-year alcohol use disorder and drug use disorder across all ages (18-65 years) although the magnitude of the disparity varies by age. Sexual minorities were also more likely to experience major depressive episode, generalized anxiety disorder, tobacco use disorder, sexually transmitted infection, and cardiovascular disease, but only at specific ages.

CONCLUSIONS

Sexual minority health disparities vary appreciably across the adult lifespan, thus elucidating critical periods for focused prevention efforts.

Tobacco Use Among Adults by Sexual Orientation: Findings from the Population Assessment of Tobacco and Health Study

PURPOSE

The aim of this study was to characterize lifetime tobacco use across two measures of sexual orientation and six types of tobacco products.

METHODS

We conducted a cross-sectional analysis of the Population Assessment of Tobacco and Health (Wave 1, 2013-2014, USA) to estimate the prevalence of tobacco use (cigarettes, e-cigarettes, cigars, pipes, hookah, and smokeless) stratified by gender (men/women), age (< 25/≥ 25 years old), and sexual orientation. Sexual orientation was operationalized as sexual identity and sexual attraction.

RESULTS

Younger lesbian/gay and bisexual women had higher relative odds of experimental use of all six tobacco products compared to heterosexual women, whereas lesbian/gay and bisexual women in both age groups had higher odds of regular use of cigarettes, e-cigarettes, cigars, and hookah than heterosexual women. Younger gay men (but not older gay men) had higher relative odds of experimental and regular use of cigarettes compared to heterosexual men. Older gay men had higher odds of experimental e-cigarette and hookah use, but lower odds of regular cigar and experimental/regular smokeless tobacco use. Measures of sexual orientation identity and sexual attraction resulted in similar estimates of tobacco use with noted differences in those who identified as "something else," as well as among those who indicated asexual attraction.

CONCLUSION

Our findings reflect a complex relationship between sexual orientation and tobacco use. Gender-based and product-specific approaches to tobacco prevention and control efforts are needed to address the high use of tobacco among sexual minority women.

Sexual Orientation Disparities in Physical Activity: Results From Insured Adults in California

BACKGROUND

The majority of adults in the United States fail to meet the Centers for Disease Control and Prevention (CDC) physical activity (PA) guideline recommendations for health promotion. Despite evidence of disparities by sexual orientation in adverse health outcomes related to PA, little is known about whether PA patterns and the likelihood of meeting these guidelines differ between heterosexual and sexual minority (SM) men and women.

METHODS

In 2018, we pooled unweighted respondent data from Kaiser Permanente Northern California Member Health Surveys conducted in 2008, 2011, and 2014/15 (N=42,534) to compare PA patterns among heterosexual and SM men and women.

RESULTS

In total, 38.8% of heterosexual men, 43.4% of SM men, 32.9% of heterosexual women, and 40.0% of SM women meet the CDC PA guidelines, yet there was no statistically significant difference in the adjusted odds of meeting these guidelines. Compared with heterosexual women, SM women engage in PA more frequently [odds ratio=0.81; 95% confidence interval (CI), 0.74-0.89], for more minutes per week on average (12.71; 95% CI, 4.85-20.57), and at higher levels of intensity (relative risk ratio=1.26; 95% CI, 1.02-1.56). Compared with heterosexual men, SM men engage in PA more frequently (OR=0.85; 95% CI, 0.74-0.98), for fewer minutes per week on average (-12.89; 95% CI, -25.84 to 0.06), and at lower levels of intensity (relative risk ratio=0.83; 95% CI, 0.67-0.99).

CONCLUSIONS

We find that SMs get more frequent PA than their heterosexual peers, which suggests that the higher prevalence of obesity and other PA-related adverse health outcomes among SMs may be due to factors other than PA patterns.

Sexual and gender minority cigarette smoking disparities: An analysis of 2016 Behavioral Risk Factor Surveillance System data

We examined the association between lesbian, gay, bisexual, and transgender (LGBT) identity, cigarette and e-cigarette use, and potential risk factors in the United States. Using data from 198,057 adults in 26 states in the 2016 Behavioral Risk Factor Surveillance System (BRFSS), we estimated the prevalence of cigarette use, e-cigarette use, and potential risk factors by gender identity and sexual identity. Overall and sex-stratified bivariate and multivariate logistic regressions examined whether the relationship between sexual and gender identity and cigarette and e-cigarette use persisted after adjusting for demographics, socio-economic status, and other unhealthy behaviors. After adjusting for covariates, gender minority identity was no longer associated with increased likelihood of currently smoking cigarettes and ever use of e-cigarettes. Sexual minority identity continued to be significant after adjusting for covariates, indicating that sexual identity disparities in cigarette and e-cigarette use are not fully explained by these factors. Findings varied by identity. Compared to their straight peers, likelihood of tobacco product use among LGB individuals varied between sexes, by product, and by sexual identity (gay/lesbian versus bisexual). More research is needed to understand the mechanisms that influence diverse patterns of cigarette and e-cigarette use among sexual and gender minority adults.

Provider Perspectives on the Application of Patient Sexual Orientation and Gender Identity in Clinical Care: A Qualitative Study

BACKGROUND

The federal government and other organizations have recommended that healthcare institutions collect and document patient sexual orientation and gender identity (SO/GI) information in order to advance the understanding of the health of sexual and gender minority populations and to combat existing health disparities. Little is known, however, about provider perception of the clinical relevance of, or how they might use, patient SO/GI information in individual care.

OBJECTIVE

To explore providers' perspectives on and experiences with collection of patient SO/GI information and how the knowledge of this information may impact clinical care.

DESIGN

Qualitative study using in-depth individual interviews of healthcare providers.

PARTICIPANTS

Twenty-five healthcare providers, including physicians, physician assistants, and nurse practitioners, from the fields of family medicine, internal medicine, gynecology, and urology within a single healthcare system in an east coast city.

APPROACH

Interviews were recorded and transcribed verbatim. Transcripts were coded and analyzed using principles of grounded theory and thematic analysis to identify themes emerging from the data.

KEY RESULTS

Providers recognized the importance of collecting patient SO/GI information for understanding population-level public health concerns and disparities, as well as understanding and respecting the context of patients' lives. However, providers also emphasized the importance of knowing patients' sexual behaviors and physical anatomy for addressing health risk and preventive care needs-and noted the distinction between these characteristics and patient SO/GI. Providers cautioned that assumptions based on knowledge of patient SO/GI may unintentionally obscure accurate profiles of patient behavior and anatomy.

CONCLUSIONS

Along with the potential benefits of routine collection of patient SO/GI, it is important that providers continue to inquire about patient behaviors and anatomy to inform individual risk and needs assessments. Findings from this study can inform the development of guidelines, trainings, and practices for incorporation of patient SO/GI along with existing assessment practices to improve individual and population health.

Sexual Orientation Group Differences in Perceived Stress and Depressive Symptoms Among Young Adults in the United States

PURPOSE

Overall, sexual minorities have poorer mental health than heterosexual individuals, and stress is thought to underlie such disparities. However, sexual minorities include both those identifying as lesbian, gay, or bisexual (LGB) and many who do not (e.g., individuals identifying as mostly heterosexual, or as heterosexual but with discordant same-sex attractions or behaviors), and little is known about the mental health or stress experiences of non-LGB identified sexual minorities. This study assessed perceived stress and depressive symptom differences between concordant heterosexual individuals and three groups of sexual minority young adults (LGB, mostly heterosexual, and discordant heterosexual individuals).

METHODS

Data were from the National Longitudinal Study of Adolescent to Adult Health, Wave IV (2008-2009). Descriptive and bivariate statistics were estimated. Path analyses assessed whether perceived stress mediated differences in depressive symptomatology. Analyses were weighted and gender-stratified.

RESULTS

Mostly heterosexual individuals comprised the largest sexual minority group, for both men (3.58%) and women (15.88%). All sexual minority groups reported significantly more depressive symptoms than concordant heterosexual individuals, for both men and women (all P < 0.05). Among women, all sexual minority groups reported significantly higher perceived stress than concordant heterosexual individuals (all P < 0.05), which partially mediated elevations in depressive symptomatology (all P < 0.05). Mostly-heterosexual-identified men reported significantly higher perceived stress than concordant heterosexual men (P < 0.01), which partially mediated elevations in depressive symptomatology (P < 0.01).

CONCLUSIONS

Our results underscore the importance of assessing sexual orientation comprehensively to fully understand sexual minority health disparities. Additional research should examine the stressors specific to different sexual minority groups.

Sexual Orientation Discordance and Nonfatal Suicidal Behaviors in U.S. High School Students

INTRODUCTION

Studies among adults have documented association between sexual orientation discordance and some suicide risk factors. However, studies examining sexual orientation discordance and nonfatal suicidal behaviors in youth are rare. This study examines the association between sexual orientation discordance and suicidal ideation/suicide attempts among a nationally representative sample of U.S. high school students.

METHODS

Using sexual identity and sex of sexual contact measures from the 2015 national Youth Risk Behavior Survey (n=6,790), a sexual orientation discordance variable was constructed describing concordance and discordance (agreement and disagreement, respectively, between sexual identity and sex of sexual contacts). Three suicide-related questions (seriously considered attempting suicide, making a plan about how they would attempt suicide, and attempting suicide) were combined to create a two-level nonfatal suicide risk variable. Analyses were restricted to students who identified as heterosexual or gay/lesbian, who had sexual contact, and who had no missing data for sex or suicide variables. The association between sexual orientation discordance and nonfatal suicide risk was assessed using logistic regression. Analyses were performed in 2017.

RESULTS

Approximately 4.0% of students experienced sexual orientation discordance. High suicide risk was significantly more common among discordant students compared with concordant students (46.3% vs 22.4%, p<0.0001). In adjusted models, discordant students were 70% more likely to have had suicidal ideation/suicide attempts compared with concordant students (adjusted prevalence ratio=1.7, 95% CI=1.4, 2.0).

CONCLUSIONS

Sexual orientation discordance was associated with increased likelihood of nonfatal suicidal behaviors. Discordant adolescents may experience unique stressors that should be considered when developing and implementing suicide prevention programs.

Experiences of transgender individuals when accessing health care: a qualitative systematic review protocol

REVIEW QUESTION/OBJECTIVE

The objective is to synthesize existing qualitative literature examining the experiences of transgender individuals when accessing health care.

Sexual orientation disclosure in health care: a systematic review

BACKGROUND

Significant health disparities between sexual minority individuals (that is, lesbian, gay, bisexual, or transgender [LGBT]) and heterosexual individuals have been demonstrated.

AIM

To understand the barriers and facilitators to sexual orientation (SO) disclosure experienced by LGBT adults in healthcare settings.

DESIGN AND SETTING

Mixed methods systematic review, including qualitative, quantitative, and mixed methods papers following PRISMA guidelines.

METHOD

Study quality was assessed using the Mixed Methods Appraisal Tool (MMAT) and a qualitative synthesis was performed. Studies were included if their participants were aged ≥18 years who either identified as LGBT, had a same-sex sexual relationship, or were attracted to a member of the same sex.

RESULTS

The review included 31 studies representing 2442 participants. Four overarching themes were identified as barriers or facilitators to SO disclosure: the moment of disclosure, the expected outcome of disclosure, the healthcare professional, and the environment or setting of disclosure. The most prominent themes were the perceived relevance of SO to care, the communication skills and language used by healthcare professionals, and the fear of poor treatment or reaction to disclosure.

CONCLUSION

The facilitators and barriers to SO disclosure by LGBT individuals are widespread but most were modifiable and could therefore be targeted to improve healthcare professionals' awareness of their patients' SO. Healthcare professionals should be aware of the broad range of factors that influence SO disclosure and the potential disadvantageous effects of non-disclosure on care. The environment in which patients are seen should be welcoming of different SOs as well as ensuring that healthcare professionals' communication skills, both verbal and non-verbal, are accepting and inclusive.

Prevalence of Self-Reported Diabetes by Sexual Orientation: Results from the 2014 Behavioral Risk Factor Surveillance System

PURPOSE

This study aimed to compare the prevalence of self-reported diabetes and diabetes risk factors among adult sexual minority and heterosexual populations in the United States.

METHODS

Data from the 2014 Behavioral Risk Factor Surveillance System for 3776 lesbian, gay, and bisexual (LGB) adults and 142,852 heterosexual adults aged 18 years and older were used to estimate the prevalence of diabetes. Binomial logistic regression models were used to compare the odds of diabetes by sexual orientation.

RESULTS

Sexual minorities were younger and more racially diverse than heterosexuals. Gay men less often and lesbian and bisexual women more often reported a body mass index of 30 kg/m2 or higher than heterosexuals. Overall, 14.2% of bisexual men, 11.4% of gay men, and 10.8% of heterosexual men reported a lifetime diabetes diagnosis, as did 8.5% of lesbian women, 5.7% of bisexual women, and 10.2% of heterosexual women. After controlling for multiple factors, gay (odds ratio [OR] = 1.50; confidence interval [95% CI] = 1.09-2.07) and bisexual men [OR = 1.55; 95% CI = 1.00-2.07] were more likely to report a lifetime diabetes diagnosis than heterosexual men. Similar differences were not found for lesbian [OR = 1.22; 95% CI = 0.76-1.95] or bisexual women [OR = 0.88; 95% CI = 0.62-1.26].

CONCLUSION

Sexual minorities may be at increased risk for diabetes than their heterosexual peers. This may be due partly to the chronic stressors associated with being a member of a marginalized population. Future research should explore the underlying causes and consequences of LGB diabetes disparities and elucidate best practices to improve diabetes screening and care for these vulnerable patient populations.

Health and healthcare disparities among U.S. women and men at the intersection of sexual orientation and race/ethnicity: a nationally representative cross-sectional study

Background

Research has shown that sexual minorities (SMs) (e.g. lesbian, gay, and bisexual individuals), compared to their heterosexual counterparts, may engage in riskier health behaviors, are at higher risk of some adverse health outcomes, and are more likely to experience reduced health care access and utilization. However, few studies have examined how the interplay between race and sexual orientation impacts a range of health measures in a nationally representative sample of the U.S. population.

Methods

To address these gaps in the literature, we sought to investigate associations between sexual orientation identity and health/healthcare outcomes among U.S. women and men within and across racial/ethnic groups. Using 2013–2015 National Health Interview Survey data (N = 91,913) we employed Poisson regression with robust variance to directly estimate prevalence ratios (PR) comparing health and healthcare outcomes among SMs of color to heterosexuals of color and white heterosexuals, stratified by gender and adjusting for potential confounders.

Results

The sample consisted of 52% women, with approximately 2% of each sex identifying as SMs. Compared to their heterosexual counterparts, white (PR = 1.25 [95% confidence interval (CI): 1.08–1.45]) and black (1.54 [1.07, 2.20]) SM women were more likely to report heavy drinking. Hispanic/Latino SM women and men were more likely to experience short sleep duration compared to white heterosexual women (1.33 [1.06, 1.66]) and men (1.51 [1.21, 1.90). Black SM women had a much higher prevalence of stroke compared to black heterosexual women (3.25 [1.63, 6.49]) and white heterosexual women (4.51 [2.16, 9.39]). White SM women were more likely than white heterosexual women to be obese (1.31 [1.15, 1.48]), report cancer (1.40 [1.07, 1.82]) and report stroke (1.91 [1.16, 3.15]. White (2.41 [2.24, 2.59]), black (1.40[1.20, 1.63]), and Hispanic/Latino SM (2.17 [1.98, 2.37]) men were more likely to have been tested for HIV than their heterosexual counterparts.

Conclusions

Sexual minorities had a higher prevalence of some poor health behaviors, health outcomes, and healthcare access issues, and these disparities differed across racial groups. Further research is needed to investigate potential pathways, such as discrimination, in the social environment that may help explain the relationship between sexual orientation and health.

Dimensions of sexual orientation and sleep disturbance among young adults

We examined associations among 3 dimensions of sexual orientation (identity, attraction, and behavior) and sleep disturbance among young adults in the United States. Using Wave IV of the National Longitudinal Study of Adolescent Health (respondents aged 24–32, N = 14,334), we ran multivariate logistic regressions to estimate the probability of reporting trouble falling asleep, trouble staying asleep, and short sleep duration, based on specific sexual orientation categories.

Results after controlling for mental health indicate that these categories are more likely to have trouble falling asleep: women who identify as “bisexual” (OR = 1.85, CI: 1.21,2.82), women attracted to “both sexes” (OR = 1.31, CI: 1.00,1.72), women who have had “mostly opposite sex” partners (OR = 1.40, CI: 1.10,1.77), and men who have had “mostly same sex” partners (OR = 2.28, CI: 1.21,4.31). For trouble staying asleep: women who identify as “bisexual” (OR = 1.48, CI: 1.01,2.18), men and women attracted to “both sexes” (OR = 1.81, CI: 1.12,2.91; OR = 1.27, CI: 1.00,1.60), and women who have had “mostly opposite sex partners” (OR = 1.38, CI: 1.13,1.69). For short sleep duration: women who identify as “mostly straight” or “mostly gay” (OR = 1.27, CI: 1.01,1.60; OR = 2.64, CI: 1.36,5.14), men who identify as “bisexual” (OR = 2.56, CI: 1.26,5.18), women attracted only to “same sex” (OR = 2.42, CI: 1.48,3.96), men attracted to “both sexes” (OR = 1.88, CI: 1.21,2.93), and women who have had “mostly same sex” partners (OR = 4.90, CI: 2.10,11.46). Given the variation in findings, it is necessary to analyze each sexual orientation dimension and the categories within each dimension to adequately understand sleep disturbances among sexual minority populations.

•

Sleep disturbances across sexual identity, sexual attraction, and sexual behavior are analyzed.

•

Specific intermediate categories of sexual orientation are more at-risk for sleep disturbances.

•

Mental health helps to explain sleep disturbances among sexual minority men more than among women.

Measuring Sexual Orientation: A Review and Critique of U.S. Data Collection Efforts and Implications for Health Policy

The U.S. Department of Health and Human Services' (HHS) Healthy People 2020 goals sought to improve health outcomes among sexual minorities; HHS acknowledged that a dearth of sexual orientation items in federal and state health surveys obscured a broad understanding of sexual minority-related health disparities. The HHS 2011 data progression plan aimed to advance sexual orientation data collection efforts at the national level. Sexual orientation is a complex, multidimensional construct often composed of sexual identity, sexual attraction, and sexual behavior, thus posing challenges to its quantitative and practical measurement and analysis. In this review, we (a) present existing sexual orientation constructs; (b) evaluate current HHS sexual orientation data collection efforts; (c) review post-2011 data progression plan research on sexual minority health disparities, drawing on HHS survey data; (d) highlight the importance of and (e) identify obstacles to multidimensional sexual orientation measurement and analysis; and (f) discuss methods for multidimensional sexual orientation analysis and propose a matrix for addressing discordance/branchedness within these analyses. Multidimensional sexual orientation data collection and analysis would elucidate sexual minority-related health disparities, guide related health policies, and enhance population-based estimates of sexual minority individuals to steer health care practices.

Pubertal Stress and Nutrition and their Association with Sexual Orientation and Height in the Add Health Data

A number of studies have indicated that gay men tend to be shorter, on average, than heterosexual men. Less evidence exists that lesbian women are taller, on average, than heterosexual women. The most popular explanation of the association between sexual orientation and height involves prenatal factors, such that, for example, gay men may have been exposed to lower than typical androgens during fetal development, which impacts their height and sexual orientation as adults. An alternative explanation involves stress, given that stress has been associated with sexual minority identification and with lower height. Another alternative explanation involves nutrition, although its relationship is less clear with sexual minority identification. Using the Add Health data, which is a large, nationally representative and longitudinal sample of American adolescents (n = 14,786), we tested a mediation model, such that sexual orientation → pubertal stress/nutrition → height. Within men, we found that gay men (n = 126) were shorter, on average, than heterosexual men (n = 6412). None of the 24 pubertal stress-related and 15 pubertal nutrition-related variables assessed in the Add Health data mediated the relationship between sexual orientation and height in men. Within women, lesbians (n = 75) did not differ significantly in stature compared to heterosexual women (n = 6267). Thus, prenatal mechanisms (e.g., hormones, maternal immune response) are likely better candidates for explaining the height difference between gay men and heterosexual men.

Sexual Orientation, Objective Height, and Self-Reported Height

Studies that have used mostly self-reported height have found that androphilic men and women are shorter than gynephilic men and women, respectively. This study examined whether an objective height difference exists or whether a psychosocial account (e.g., distortion of self-reports) may explain these putative height differences. A total of 863 participants, recruited at a Canadian university, the surrounding region, and through lesbian, gay, bisexual, and transgender (LGBT) events across Canada, self-reported their height and had their height measured. Androphilic men were shorter, on average, than gynephilic men. There was no objective height difference between gynephilic, ambiphilic, and androphilic women. Self-reported height, statistically controlling for objective height, was not related to sexual orientation. These findings are the first to show an objective height difference between androphilic and gynephilic men. Also, the findings suggest that previous studies using self-reported height found part of a true objective height difference between androphilic and gynephilic men. These findings have implications for existing biological theories of men's sexual orientation development.

Minority stress, psychological distress, and alcohol misuse among sexual minority young adults: A resiliency-based conditional process analysis

BACKGROUND

Sexual minority young adults experience elevated rates of distal stress (discrimination, victimization), and related psychological distress and alcohol misuse. However, few studies have examined the degree to which personality trait differences confer risk/resilience among sexual minority young adults. We hypothesized that psychological distress would mediate the relationship between distal stress and alcohol misuse, but that these relationships would be moderated by personality trait differences.

METHOD

Sexual minority young adults (N=412) were recruited nationally. Survey measures included demographic questions, minority stressors, Five Factor personality traits, and current psychological distress and alcohol misuse symptoms. We used a data-driven two-stage cluster analytic technique to empirically derive personality trait profiles, and conducted mediation and moderated mediation analyses using a regression-based approach.

RESULTS

Our results supported a two-group personality profile solution. Relative to at-risk individuals, those classified as adaptive scored lower on neuroticism, and higher on agreeableness, extraversion, conscientiousness, and openness to experience. As predicted, psychological distress mediated the relationship between distal stress and alcohol misuse. However, personality moderated these relationships to the degree that they did not exist among individuals classified as adaptive.

DISCUSSION

In the current study, we found that personality moderated the established relationships between distal stress, psychological distress, and alcohol misuse among sexual minority young adults. Future research is needed to further explicate these relationships, and in order to develop tailored interventions for sexual minority young adults at risk.

Happiness and Sexual Minority Status

We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

Adapting to Injustice

In this study, we link together moments of discrimination described by young bisexual women. We do so in order to theorize about associations between negative stereotypes heard early in one’s life and later minimization of personal discrimination. Using interviews with 13 young women, we sought to understand the types of negative messages participants heard about “bi/sexuality” as well as the ways that they perceived or did not perceive themselves as having experienced discrimination related to their sexuality. We found that family members and friends often described participants’ bisexuality as “disgusting,” “difficult to understand,” or “hot,” and participants described their own experiences with discrimination as “no big deal.” We use this analysis to build on previous research concerning microaggressions, sexual stigma, and denial of discrimination to discuss how familial, social, and political environments create a set of conditions in which later injustices are imagined as normative and inevitable. Finally, we discuss the methodological dilemmas facing feminist psychologists who aim to analyze discrimination and the challenges in documenting individuals’ experiences of stigma, which may be imagined as no big deal to individuals, but are in fact unjust. It is imperative to develop strategies to recognize, document, and critically assess how injustice becomes all too normal for some and the role that feminist psychology can play in changing this.

The LGB Mormon Paradox: Mental, Physical, and Self-Rated Health Among Mormon and Non-Mormon LGB Individuals in the Utah Behavioral Risk Factor Surveillance System

Much of the literature on mental and physical health among religious LGB individuals has relied on small-N convenience samples. This study takes advantage of a unique, large-N, population-based dataset to test the relationship between religious identity, religious activity, and health, with a specific emphasis on Utah Mormons. In a surprising finding, Mormon LGBs report better mental health than non-Mormon LGBs, while their self-rated and physical health is not significantly different. However, there is some evidence that Mormon LGBs derive fewer health benefits from church attendance than their non-LGB Mormon counterparts. These results may nuance the conventional wisdom regarding the health dynamics of LGB individuals who identify with a conservative, heteronormative religious tradition, and plausible explanations are discussed.

Mental health of sexual minorities. A systematic review

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.
