Early roots of sexual-orientation health disparities: associations between sexual attraction, health and well-being in a national sample of Australian adolescents

Prevalence, severity and risk factors for mental disorders among sexual and gender minority young people: a systematic review of systematic reviews and meta-analyses

Evidence suggests heightened prevalence and severity of mental disorders among sexual minority (SM) and gender minority (GM) young people. Several risk factors have been associated with these disparities. A systematic review of systematic reviews and meta-analysis was conducted to provide a comprehensive overview of the literature and to determine the field's current position. MEDLINE, PsycInfo, Scopus and Web of Science were searched in March 2022 and updated January 2024. Eligibility criteria were systematic reviews or meta-analyses assessing contemporaneous prevalence, severity and/or risk factors of mental disorders among SM or GM young people aged 25 and under. 42 reviews were included, all of which were low quality. The prevalence of depression among SM was 26% (95% CI 21-32%), and among GM was 46% (95% CI 36-56%). Greater depression severity was found among SM compared to heterosexual young people, with a significant albeit small effect size (Hedges' g = 0.38, 95% CI = 0.25 to 0.50); effect sizes were similar when separating by gender. GM also reported greater symptom severity compared to cisgender young people. Other mental disorders were more prevalent compared to those reported in the general population, and of greater severity compared to heterosexual/cisgender young people. Several proximal and distal risk factors were focused upon within the systematic reviews identified. Past systematic reviews consistently indicate a heightened risk of mental disorders among SM and GM young people. Services need to be aware of these disparities and adapt their care accordingly.

Risk and protective factors for suicidality among lesbian, gay, bisexual, transgender, and queer (LGBTQ+) young people, from countries with a high global acceptance index (GAI), within the context of the socio-ecological model: A scoping review

INTRODUCTION

Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) young people experience higher prevalence rates of suicidality than their heterosexual and/or cisgender peers. However, there is limited research that can inform suicide prevention efforts. Our aim was to synthesize quantitative, qualitative, and mixed methods research on risk and protective factors among LGBTQ+ young people, from countries with a high Global Acceptance Index.

METHODS

A scoping review guided by Arksey and O'Malley's five-stage framework, using the Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews protocol. Five databases and grey literature were searched for relevant studies. Identified factors were clustered by thematic type, according to the socio-ecological model to identify empirical trends and knowledge gaps. The mixed methods appraisal tool was used for quality assessment of studies.

RESULTS

Sixty-six studies met our inclusion criteria. Overall, 59 unique risk factors and 37 unique protective factors were identified. Key risk factors include past suicidality, adverse childhood experiences, internalized queerphobia, minority stress, interpersonal violence, bullying, familial conflict, and anti-LGBTQ+ policies/legislation. Key protective factors include self-affirming strategies, adult/peer support, at-school safety, access to inclusive healthcare, family connectedness, positive coming out experiences, gender-affirming services and LGBTQ+ inclusive policies and legislation.

CONCLUSIONS

Overall, our findings affirm that multiple risk and protective factors, at all levels of the socio-ecological model, interact in complex, unique and diverse ways upon suicidality among LGBTQ+ young people. Implications for suicide prevention are discussed. Further empirical studies are required, particularly at the communities, policies, and societal levels of the socio-ecological model, and these studies should include a focus on protective factors and significant within-group differences.

Gender and sexual identity-based inequalities in adolescent wellbeing: findings from the #BeeWell Study

BACKGROUND

Gender and sexual minority adolescents experience greater symptoms of psychological distress than their peers, but little is known about broader aspects of their wellbeing. This study examines wellbeing inequalities relating to gender and sexual identity among adolescents from Greater Manchester in the United Kingdom.

METHOD

37,978 adolescents (aged 12-15, attending 165 secondary schools) completed surveys of life satisfaction, positive and negative affect (hedonic framework); autonomy, self-esteem, optimism, and positive relationships (eudaimonic framework); and, symptoms of distress and mental wellbeing (complete state framework). Structural correlated factors models were used to assess gender and sexual identity wellbeing inequalities.

RESULTS

The magnitude of wellbeing inequalities pertaining to gender and sexual identity were routinely substantially greater than those concerning other characteristics (e.g., socio-economic disadvantage). Gender identity wellbeing inequalities followed a consistent pattern, with the largest disparities evident between gender diverse adolescents and boys. Sexual identity wellbeing inequalities also followed a consistent pattern, with the largest disparities evident between sexual minority youth (both gay/lesbian and bi/pansexual) and their heterosexual peers. Finally, variation was evident across wellbeing domains. For example, observed gender identity (boys vs. girls) and sexual identity (heterosexual vs. sexual minority) disparities were substantially greater for symptoms of distress than for mental wellbeing in the complete state model.

CONCLUSIONS

LGBTQ + adolescents experience lower wellbeing than their peers, and this is evident across a range of wellbeing domains. Accordingly, there is an urgent need for the prioritisation of improved prevention and intervention efforts that can better meet the needs of gender diverse and sexual minority youth, and future research should be conducted to improve understanding of the mechanisms underpinning the wellbeing inequalities observed.

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.

Childhood and Adolescence Gender Role Nonconformity and Gender and Sexuality Diversity in Young Adulthood

Importance

Sexuality- and gender-diverse youth experience disproportionate health and social adversity. Accurate early-life indicators are important for development of supportive approaches.

Objective

To examine whether commonly used items measuring childhood conformity to gender roles are associated with sexual orientation in young adulthood.

Design, Setting, and Participants

This single-center, prospective cohort study (the Raine Study) assessed 2868 children of 2900 women who were recruited during pregnancy from August 1, 1989, to April 30, 1992, with follow-up ongoing. The Achenbach System of Empirically Based Assessment (ASEBA) Child Behavior Checklist, Teacher Report Form, and Youth Self-Report tools were used to survey parents, teachers, and youths to examine gender diversity among the participating youths. Parents were followed up at years 5, 8, 10, 14, and 17, adolescents at years 14, 17, and 27, and teachers at years 10 and 14. Data were analyzed from August 1, 2020, to July 31, 2023.

Exposures

Parent and teacher report that a child "behaves like the opposite sex" (gender role behavior), and parent and self-report that a child "wishes to be the opposite sex" (gender role wish), in response to assessment items.

Main Outcome Measures

Year 27 self-reported sexual identity, attraction, and behavior.

Results

Of the 2868 children in the original birth cohort, 1154 (40.2%) participated in the year 27 follow-up, of whom 608 (52.7%) were recorded female at birth and 546 (47.3%) were recorded male at birth. Of these, 582 who were recorded female at birth continued to identify as female (cisgender) (95.7%), and 515 recorded male at birth continued to identify as male (cisgender) (94.3%); 47 (4.1%) did not complete the questionnaire. Of cisgender participants, 76 of 605 women (12.6%) and 52 of 540 men (9.6%) had a diverse sexual identity, 204 of 605 women (33.8%) and 77 of 540 men (14.3%) were same-gender attracted, and 100 of 605 women (18.6%) and 39 of 540 men (7.2%) had ever engaged in same-gender sexual behavior. Across all follow-ups, after adjusting for gender, nonconforming gender role behavior was consistently associated with diverse sexual identity and behavior (adjusted odds ratio [aOR] for identity, 2.8; 95% CI, 1.9-4.2; behavior aOR, 2.4; 95% CI, 1.6-3.5). Self-reported gender role wish was consistently associated with diverse sexual orientation (identity aOR, 2.3; 95% CI, 1.4-3.8; attraction aOR, 1.7; 95% CI, 1.1-2.5; behavior aOR, 1.9; 95% CI, 1.2-2.9).

Conclusions and Relevance

In this cohort study, ASEBA gender role nonconformity was associated with diverse sexual orientation, beginning in early childhood. Findings suggest that the ASEBA measures should not be used to infer sexual orientation or gender diversity in clinical or research settings; asking direct questions may provide more accurate data.

Maltreatment experiences and mental health indicators among elite athletes

This study explored the relationships between athletes' experiences of maltreatment and mental health indicators. Canadian National Team athletes completed an online, anonymous survey that assessed reported experiences of maltreatment (psychological, physical, sexual harm and neglect), and mental health indicators of well-being, eating disorders and self-harming behaviours. All forms of maltreatment had a significant, positive correlation with eating disorder and self-harming behaviours, and a negative correlation with well-being. The relationships between maltreatment and mental health indicators differed based on identity characteristics of the athletes. Further work is needed on the prevention and intervention of maltreatment in sport to reduce the behaviours associated with negative health outcomes.

The influence of minority stress-related experiences on mental wellbeing for trans/gender-diverse and cisgender youth: a comparative longitudinal analysis

Trans and gender-diverse (TGD) adolescents are likely to experience poorer mental health and wellbeing than their cisgender peers. Minority stress theory has developed as a possible explanation for some of this disadvantage: factors such as increased bullying and discrimination lead to excess stress and reduced wellbeing. However, the evidence base remains limited. This study drew on secondary data analysis of the #BeeWell longitudinal cohort over 2 years (N = 26 042, aged 12-13 at time one, T1). We report two unregistered hypotheses relating to T1 (autumn 2021) data which was available at the time of stage-one submission: H1, mean differences in T1 wellbeing; H2, mean differences in T1 minority-related stressors. These are followed by two registered hypotheses relating to T2 (autumn 2022) data: H3, replication of T1 mean differences in T2 wellbeing; H4, predictions were made about the strength of the association between T1 minority-related stressors, controlling for sexuality and T2 wellbeing across T1 gender identity groups. At both time points cis-females, TGD and those who preferred not to say their gender had lower wellbeing than cis-males (CM), with the largest effect evident for the TGD group. TGD adolescents also showed the largest disadvantage (mean difference) compared with CM for minority stressors. Counter to H4 and minority stress theory, gender was not found to moderate the effect of minority stressors on later wellbeing. Our findings highlight the vulnerability of the TGD group in terms of wellbeing and minority stressors and are discussed with relevance for policy and future research.

Sexual orientation disparities in the developmental trajectories of emotional and behavioral difficulties from childhood to early adolescence

BACKGROUND

Lesbian, gay, bisexual, and asexual adolescents are at increased risk of poor mental health outcomes but it remains unknown whether this disparity emerges from early childhood and through to adolescence. This study tested sexual orientation disparities in the developmental trajectories of emotional and behavioral difficulties from ages 5 to 14 years, and the influence of early life adversities upon them.

METHODS

The Millennium Cohort Study, a British birth cohort, was used (4,838 boys and 5,016 girls). Parent-report emotional and behavioral difficulties at ages 5, 7, 11, and 14 were measured using the Strength and Difficulties Questionnaire. Sexual orientation was measured via sexual attraction at age 17. Early life adversities in the first 5 years of life, including parental age at birth, birthweight, duration of breastfeeding, parent-child relationship quality, and parental absence, were collected prospectively.

RESULTS

Latent growth modeling suggested that, for both sexes, sexual orientation disparities in emotional and behavioral difficulties increased from age 5 to 14 years. Homosexual and bisexual girls displayed significantly greater emotional and behavioral difficulties than heterosexual girls at ages 7, 11, and 14. Homosexual and bisexual boys displayed significantly greater emotional and behavioral difficulties than heterosexual boys at ages 11 and 14. Asexual boys and girls displayed significantly greater emotional and behavioral difficulties than their heterosexual counterparts at all four ages. For both sexes, sexual orientation disparities in emotional and behavioral difficulties only reduced slightly in magnitude after controlling for early life adversities.

CONCLUSIONS

Sexual minority disparities in emotional and behavioral difficulties increased from childhood to early adolescence, possibly due to the accumulation of susceptibility to minority-related stressors. Sex and early life adversity may contribute to these developmental disparities.

Neuroticism and Sexual Orientation-Based Victimization as Mediators of Sexual Orientation Disparities in Mental Health

This study tested whether elevated risk of poorer mental health outcomes among nonheterosexual adolescents compared with heterosexual adolescents is plausibly explained by neuroticism and sexual orientation-based victimization. The Millennium Cohort Study, a large British prospective birth cohort, was used (4566 heterosexual boys, 77 bisexual boys, 129 homosexual boys, 96 asexual boys, 4444 heterosexual girls, 280 bisexual girls, 158 homosexual girls, and 182 asexual girls). We analyzed the following measures assessed at age 17 years: sexual orientation based on sexual attraction, neuroticism, sexual orientation-based victimization, self-harm attempts, and psychological well-being. Mediation analysis was undertaken separately by sex and yielded the following statistically significant findings: for both sexes, we found that bisexual and homosexual adolescents scored higher than heterosexual adolescents on neuroticism; for both sexes, bisexual and homosexual adolescents reported more negative psychological well-being scores and self-harm attempts compared with heterosexual adolescents, with total effects (standardized regression coefficients) ranging from .58 to .91; those associations were mediated through sexual orientation-based victimization and neuroticism scores, with the indirect effects (standardized regression coefficients) through sexual orientation-based victimization and neuroticism scores ranging from .09 to .26 and .16 to .55, respectively. Asexual adolescents did not differ significantly from their heterosexual counterparts in psychological well-being and self-harm attempts, with the total effects ranging from - .02 to .21. Sexual orientation-based victimization and neuroticism may both contribute to the sexual orientation-related disparities in psychological well-being and self-harm attempts. However, neuroticism appears to the more powerful factor.

Self-harm and suicidality among LGBTIQ people: a systematic review and meta-analysis

Research evidence has consistently documented a higher risk of suicidality in the Lesbian, Gay, Bisexual, Transgender, Intersex, and Queer (LGBTIQ) population. This systematic review and meta-analysis aimed to report a detailed description of research data regarding the risk of Attempted Suicide (SA), Suicide Ideation (SI), and Non-Suicidal Self-Injury (NSSI) behaviours for LGBTIQ people and their subgroups. Medline, Scopus, PsycINFO, and EMBASE were searched for studies reporting a comparative estimation of SA, SI, and NSSI rates among LGBTIQ population and the general population (i.e. heterosexual/cisgender), without restrictions on participants' age and setting for the enrolment. Pooled analyses were based on odds ratios (ORs, with 95% CIs), estimated through inverse variance models with random effects. Fifty studies were selected for the quantitative synthesis and included fifty samples involving 3.735.601 controls and 87.252 LGBTIQ people. LGBTIQ people reported an increased risk of SA (OR:4.36[95%CI:3.32;5.71]), SI (OR:3.76[95%CI:3.02;4.69]), and NSSI (OR:4.24[95%CI:3.23;5.55]). Among LGBTIQ subgroups, the Bisexual group has shown the highest risk of suicidality (SA, OR:6.71; SI, OR:5.04; NSSI, OR: 5.03), followed by the Lesbian-Gay for attempted suicide (SA, OR:6.03), and the Transgender-Intersex-Queer for suicide ideation and non-suicidal self-injury (SI and NSSI, OR:3.42). The quality of the evidence ranged from low to moderate. Our findings have shown that LGBTIQ people report a higher risk of suicidality compared with their cisgender/heterosexual peers. This evidence may contribute to the public awareness on LGBTQI mental health needs and suggest supportive strategies as well as preventive interventions (e.g. supportive programs, counselling, and destigmatizing efforts) as parts of a tailored health-care planning aimed to reduce psychiatric morbidity and mortality in this at-risk population.

The Role of Interpersonal Relationships and Household Socioeconomic Status in the Association Between Sexual Orientation and Health: A Moderated Mediation Analysis

Purpose: Emerging studies indicate that sexual minority youths experience worse health than their heterosexual peers, but few studies have examined the intervening mechanisms linking sexual orientation and health status. This study hypothesizes that interpersonal relationships, moderated by household socioeconomic status (HSES), are important mediators in the association between sexual orientation and health status. Methods: A total of 49,084 youths, consisting of 9499 youths who identified as sexual minority individuals and 39,585 youths who identified as heterosexual, were sampled from a national study on sexual and reproductive health conducted in China. Logistic regression analyses were performed to estimate the association between sexual orientation and self-rated health. Causal mediation and moderated mediation analyses were performed to analyze the mediating and moderating effects of interpersonal relationships and HSES, respectively. Results: Self-rated health was significantly poorer for sexual minority youths compared with heterosexual youths (p < 0.01). From 7.90% to 25.74% of the association between sexual orientation and self-rated health was mediated through poor interpersonal relationships with both parents and peers. A poor relationship with the father accounted for the highest percentage. HSES was found to moderate the mediation effect of interpersonal relationships, with the greatest effect found for sexual minority youths with lower HSES. Conclusion: HSES moderated the indirect effects of interpersonal relationships on the association between sexual orientation and self-rated health. Interventions focused on improving interpersonal relationships for sexual minority youths, especially those with low HSES, merit attention.

Structural stigma and sexual orientation disparities in healthcare use: Evidence from Australian Census-linked-administrative data

This study explores the extent to which structural stigma (which encompasses sociocultural and institutional constraining factors) is associated with sexual orientation disparities in healthcare service and prescription medicine use. Using the responses to the 2017 Australian Marriage Law Postal Survey, we use the regional percentage of votes against legalising same-sex marriage as a measure of structural stigma. We then map these results to Census-linked-administrative data, including 83,519 individuals in same-sex relationships - one of the largest administrative datasets to date where individuals in same-sex relationships are identified. Controlling for regional and individual-level confounders, we find that structural stigma is associated with increased use of nervous system medications (which largely comprise antidepressants) but reduced GP visits for both females and males in same-sex relationships. More regional stigma is also associated with reduced use of pathology services and anti-infective prescriptions for males in same-sex relationships. Altogether, our results suggest that individuals in same-sex relationships living in stigmatised regions are in poorer health but are less likely to access primary healthcare.

Health Disparities Between Sexual Minority and Different-Sex-Attracted Adolescents: Quantifying the Intervening Role of Social Support and School Belonging

Purpose: An emerging literature documents that sexual minority youth experience significantly and substantially worse health than their heterosexual peers, but few studies have examined the intervening mechanisms linking adolescents' sexual orientation to their health outcomes. This study hypothesized that social support from parents and friends and school belonging would act as important mediators of this relationship and is among the first to test this proposition empirically. Methods: The analyses used rich data from an Australian national probability sample of 14-15-year olds (Longitudinal Study of Australian Children, n = 3204) and regression models to estimate the associations between sexual attraction and four high-quality indicators of adolescent health/well-being capturing health-related quality of life, socio-emotional functioning, depressive symptoms, and life satisfaction. Mediation tests were subsequently performed to quantify the extent to which three scales capturing social support from parents and friends and school belonging mediated the relationships identified. Results: Sexual minority status, social support from parents and friends, and school belonging were significantly related to all health/well-being outcomes. Sexual minority adolescents reported significantly lower levels of support and belonging. Collectively, the support and belonging variables were responsible for 49%-70% of the associations between sexual minority status and the health/well-being outcomes, with school belonging being the most important mediator. Conclusion: These findings have important implications for health equity policy and practice. They suggest that interventions designed to improve the health/well-being of sexual minority adolescents should be directed at eliciting enhanced social support from families and peers and fostering integration at school. School-based interventions may be particularly fruitful.

Mental-health disparities between heterosexual and sexual-minority adolescents: Examining the role of informant discrepancies

INTRODUCTION

An emerging literature documents substantial mental-health disparities by sexual orientation amongst adolescents, with sexual-minority youth exhibiting poorer mental health than heterosexual youth. This brief report provides the first empirical account of how the association between sexual-minority status and adolescent mental health differs depending on who assesses adolescents' mental health (child/mother/father/teacher), and how informant discrepancies in assessments of adolescent mental health differ by adolescents' sexual orientation.

METHODS

Data come from an Australian national sample of 14-/15-year-old adolescents (Longitudinal Study of Australian Children; n~3,000). Adolescent mental health is measured using multiple measures from the Strengths and Difficulties Questionnaire, and modelled using multivariable linear regression models.

RESULTS

Mental-health disparities between sexual-minority and heterosexual adolescents emerged irrespective of who assessed the child's mental health. However, their magnitude varied substantially by informant, being largest when mental-health was reported by adolescents (~0.7 standard deviations) and smallest when reported by teachers (~0.2 standard deviations). Discrepancies between mental-health scores collected from the child and other informants were largest for internalising than externalising behaviours, and in child-father than child-mother comparisons.

CONCLUSIONS

Understanding informant discrepancies and their meaning is pivotal to designing surveys that generate robust insights into the health of sexual-minority adolescents, as well as appropriate policy interventions.
