Is Young Adulthood a Critical Period for Suicidal Behavior among Sexual Minorities? Results from a US National Sample

Structural Stigma and Disparities in Long-Term Health Conditions Among Australians in Same-Sex Relationships: 2021 Australian Census

Objectives.  To explore the extent to which structural stigma (sociocultural and institutional constraining factors) is associated with sexual orientation disparities in long-term health conditions. Methods.  We measured structural stigma using the regional percentage of votes against same-sex marriage from Australia's 2017 Marriage Equality Survey and mapped this to the 2021 Census survey of 10 093 399 and 136 988 individuals in different-sex and same-sex relationships, respectively. Controlling for individual and area-level confounders, we used logistic regression analyses to examine the association between quartiles of structural stigma and sexual orientation disparities in long-term health conditions (e.g., any, mental health, asthma, cardiovascular). Results.  In the lowest stigma quartile, individuals in same-sex relationships had 56% higher odds of reporting any long-term health condition (odds ratio [OR] = 1.56; 95% confidence interval [CI] = 1.53, 1.59) and this increased to 63% in the highest stigma quartile (OR = 1.63; 95% CI = 1.58, 1.68). Effects were particularly pronounced for cardiovascular, respiratory, and mental health conditions as well as for men, younger populations, and those living in socioeconomically deprived regions. Conclusions.  Living in stigmatizing environments may have deleterious health effects for sexual minorities in Australia. Policy action and enhanced protections for sexual minorities are urgently required. (Am J Public Health.

Examining developmental assets of young Black sexual gender minority males in preventing suicidal behaviors

Black gay and bisexual male adolescents and young adults (BGBMA/YA) are at higher risk for suicidal outcomes given their minoritized and stigmatized identities at the intersection of race and sexual orientation. This study explores key developmental assets, including family support and family communication, and their role in preventing depression symptoms and suicidal outcomes among BGBMA/YA. A cross-sectional survey was administered to participants (N = 400, Mage = 23.46, SD = 2.59) recruited through Amazon M-Turk, community-based organizations, and social media sites. A path analysis was conducted to examine associations among external assets (family support, communication about sex and drugs with parents, open family communication), depression symptoms, and suicidal attempts and plan to die by suicide. About 28 % of respondents reported a suicide attempt in the past 12 months. Depression symptoms and communication about sex and drugs with parents were positively associated with plan to die by suicide. Family support was negatively associated with depression symptoms. Depression symptoms were positively associated with suicide attempts. Family support was indirectly and negatively associated with suicide attempts. Suggestions for future research and policy implications are discussed.

Gender Differences in Risks of Suicide and Suicidal Behaviors in the USA: A Narrative Review

PURPOSE OF REVIEW

We review recent research (2018-2023) on gender differences in suicidal behaviors (i.e., suicidal ideations and attempts, death by suicide). We examine research studies in the following areas: developmental period, substance use, and special populations (Veterans, sexual and gender minorities).

RECENT FINDINGS

Novel results were found in these different areas. For example, suicide rates for female youth are increasing at a faster rate relative to male youth. Further, some evidence suggests that heavy alcohol use/binge drinking is a significant and growing risk factor for suicidal behaviors in women. Military service may be a more significant risk factor for suicidal behaviors among male Veterans compared to female Veterans. Additionally, suicide rates are rising for gender minority youth/young adults. Recent research on gender differences in suicide outcomes demonstrates findings that align with previous research, as well as new insights on this important topic.

Impact of Living Arrangements of LGBTQ College Students During COVID-19

This study examines the relationships between living arrangements and educational outcomes, access to LGBTQ affirming care, sexual and gender minority (SGM) stressors, and mental health. Bivariate analyses were implemented to examine relationships between living arrangements and academic outcomes, SGM stressors, access to care, and alcohol and substance use. Differences between undergraduate and graduate students are also reported. Students who continued living on campus were less likely to report increased family rejection, transphobia, and identity concealment.

Age-varying association between depression and cognitive function among a national sample of older U.S. immigrant adults: the potential moderating role of physical activity

OBJECTIVES

This study aimed to (1) investigate age-associated trends in depression and cognition, (2) determine whether the association between depression and cognition varies across age, and (3) test whether this association is moderated by different levels of physical activity among older U.S. immigrant adults aged 60 to 80 years.

METHODS

Using national data on elderly U.S. immigrants (N = 375) from the 2011-2014 NHANES, we employed weighted intercept-only linear time-varying effect modeling (TVEM) and weighted linear TVEM to address our research questions.

RESULTS

Weighted intercept-only linear TVEM indicated no trend in depression, but its mean peaked at age 67. Cognition consistently decreased with age, reaching its lowest point at age 78. Weighted linear TVEM revealed a significant inverse association between depression and cognition at some age ranges, with the strongest association at around age 66. Yet, we did not find the moderational relation of physical activity to this age-varying association.

CONCLUSIONS

Although we observed a significant inverse relationship between depression and cognition at a certain age point, physical activity did not moderate the age-varying association. Understanding of age-varying effects on the depression-cognition interaction will promote prevention efforts targeting aging immigrant populations at highest risk for these health outcomes. Further work is needed to test moderating effects of other health behaviors on this association across age.

Structural Stigma and Sexual Minority Victimization Across 28 Countries: The Moderating Role of Gender, Gender Nonconformity, and Socioeconomic Status

OBJECTIVE

Country-level structural stigma toward sexual minority individuals (i.e., discriminatory laws and policies and prejudicial attitudes) shows robust associations with sexual minority individuals' mental health and individual-level stigma processes, such as identity concealment. Whether structural stigma is also associated with interpersonal-level stigma processes, such as victimization, is rarely studied. Whether the association between structural stigma and sexual minority individuals' interpersonal mistreatment varies across gender, gender nonconformity, and socioeconomic status also remains to be determined.

METHODS

In 2012, sexual minority adults (n = 86,308) living in 28 European countries responded to questions assessing past-12-month victimization experiences (i.e., physical or sexual attack or threat of violence). Country-level structural stigma was objectively indexed as an aggregate of national laws, policies, and population attitudes negatively affecting sexual minority individuals.

RESULTS

Country-level structural stigma was significantly associated with victimization (adjusted odds ratios [AOR]: 1.13, 95% confidence interval [CI]: 1.04-1.22; p = .004). However, this effect varied by gender, gender nonconformity, and socioeconomic status. For both sexual minority men and women, gender nonconformity and lower socioeconomic status were associated with increased risk of victimization. The strongest association between country-level stigma and victimization was found among gender nonconforming men with lower socioeconomic status (AOR: 1.32, 95% CI: 1.14-1.52; p < .001).

CONCLUSIONS

A much larger proportion of sexual minorities living in higher stigma countries reports victimization than those living in lower stigma countries. At the same time, the association between country-level structural stigma and victimization is most heavily concentrated among gender nonconforming men with lower socioeconomic status.

HIV and suicide risk across adolescence and young adulthood: an examination of socio-demographic, contextual and psychosocial risk factors for attempted suicide in a longitudinal cohort of ageing adolescents affected by HIV living in the New York City Area

Introduction

As children become adolescents and young adults (AYA), their risk for attempting suicide increases dramatically, with chronic health conditions an important risk factor. This study examined correlates of suicidality across development in AYA living with perinatally acquired HIV (AYALPHIV) and those perinatally HIV‐exposed but uninfected (AYAPHEU).

Methods

Data come from an ongoing longitudinal New York City‐based study (N = 339) with AYALPHIV and AYAPHEU interviewed every 12–18 months from 2003 to 2019 (mean enrolment age = 12 years; current mean age = 27 years). The Diagnostic Interview Schedule for Children (adolescent or young adult version) assessed psychiatric disorders and first‐reported suicide attempt. Generalized estimating equations were used to examine associations between first‐reported suicide attempt and socio‐demographic, contextual and psychosocial correlates measured concurrently across six timepoints.

Results

At enrolment, 51% of participants were female, 72% heterosexual, 60% Black and 50% Latinx. Attempted suicide was significantly higher among AYALPHIV (27%, CI 21–33%) compared to AYAPHEU (16%, CI 10–22%), with an OR of 1.74 (CI 1.04–2.92) in a model adjusting for age. For AYALPHIV, anxiety (OR 2.66, CI 1.46–4.85), mood (OR 3.62, CI 1.49–8.81) and behaviour disorders (OR 5.05, CI 2.15–11.87) and past‐year arrest (OR 3.05, CI 1.26–7.4), negative life events (OR 1.27, CI 1.11–1.46), city stress (OR 2.28, CI 1.46–3.57), pregnancy (OR 2.28, CI 1.08–4.81) and HIV stigma (OR 2.46, CI 1.27–4.75) were associated with increased odds of attempted suicide, while identifying as heterosexual (OR 0.27, CI 0.14–0.52), higher personal (OR 0.45, CI 0.26–0.80) and family self‐concept (OR 0.36, CI 0.22–0.57) were protective. Interactions by HIV status and age were found: substance use was more strongly associated with attempted suicide among AYAPHEU than AYALPHIV, while negative life events and higher religiosity were more strongly associated with increased odds of attempted suicide among AYA ≥ 19 versus ≤ 18 years.

Conclusions

AYALPHIV compared to AYAPHEU faced unique risks for attempted suicide as they age into adulthood, with the highest risk among AYALPHIV experiencing HIV stigma or pregnancy and the highest risk among AYAPHEU with substance use. Assessing for suicide risk and correlates with attention to ageing can inform preventive interventions tailored to meet AYALPHIV and AYAPHEU needs.

Achieving health equity in US suicides: a narrative review and commentary

Suicide rates in the United States (US) reached a peak in 2018 and declined in 2019 and 2020, with substantial and often growing disparities by age, sex, race/ethnicity, geography, veteran status, sexual minority status, socioeconomic status, and method employed (means disparity). In this narrative review and commentary, we highlight these many disparities in US suicide deaths, then examine the possible causes and potential solutions, with the overarching goal of reducing suicide death disparities to achieve health equity.The data implicate untreated, undertreated, or unidentified depression or other mental illness, and access to firearms, as two modifiable risk factors for suicide across all groups. The data also reveal firearm suicides increasing sharply and linearly with increasing county rurality, while suicide rates by falls (e.g., from tall structures) decrease linearly by increasing rurality, and suicide rates by other means remain fairly constant regardless of relative county urbanization. In addition, for all geographies, gun suicides are significantly higher in males than females, and highest in ages 51-85 + years old for both sexes. Of all US suicides from 1999-2019, 55% of male suicides and 29% of female suicides were by gun in metropolitan (metro) areas, versus 65% (Male) and 42% (Female) suicides by gun in non-metro areas. Guns accounted for 89% of suicides in non-metro males aged 71-85 + years old. Guns (i.e., employment of more lethal means) are also thought to be a major reason why males have, on average, 2-4 times higher suicide rates than women, despite having only 1/4-1/2 as many suicide attempts as women. Overall the literature and data strongly implicate firearm access as a risk factor for suicide across all populations, and even more so for male, rural, and older populations.To achieve the most significant results in suicide prevention across all groups, we need 1) more emphasis on policies and universal programs to reduce suicidal behaviors, and 2) enhanced population-based strategies for ameliorating the two most prominent modifiable targets for suicide prevention: depression and firearms.

Comparison of Lifetime Suicide Attempts and Recent Suicidal/Self-Harming Thoughts Among Sexual Minority and Heterosexual Utahns: Results from a Population-Based Survey

OBJECTIVE

We sought to be the first published article to report differences in population-representative prevalence of suicidal thoughts and attempts by sexual orientation.

METHOD

Data from Utah's Behavioral Risk Factor Surveillance System (BRFSS) collected for 2016 (N = 10,988) and 2017 (N = 10,251) were examined to determine differences in the prevalence of suicidal thoughts in the past 2 weeks and the lifetime prevalence of suicide attempts (i.e., any, single, and multiple) by sexual orientation.

RESULTS

3.5% of heterosexuals Utahns reported recent suicidal/self-harming thoughts in the last 2 weeks compared to 14.7% of LGB Utahns (OR = 4.73 95% CI [2.67, 8.36]). 5.8% of heterosexuals reported a lifetime prevalence of any suicidal attempts compared to 37.2% of LGB folx (OR = 9.58 95% CI [7.16, 12.81]) with similar differences occurring for single and multiple attempts. Comparing LG versus B, there was no difference in ideation or prevalence of any attempt, but bisexuals reported higher rates of multiple suicide attempts.

CONCLUSION

LGB folx in Utah are drastically more likely to have thought about suicide/self-harming in the last 2 weeks and to have attempted suicide in their lifetime when compared to heterosexuals in Utah.

Minority Stress and Suicidal Ideation and Suicide Attempts Among LGBT Adolescents and Young Adults: A Meta-Analysis

Purpose: This meta-analytic study examined associations between minority stressors and suicidal ideation and suicide attempts among LGBT adolescents and young adults (aged 12-25 years). Methods: Identified studies were screened using the inclusion and exclusion criteria. Studies had to include an association between a minority stressor and a suicidality outcome and were categorized into 10 meta-analyses. Overall effect sizes were calculated using three-level meta-analyses. In addition, moderation by sampling strategy was examined. Results: A total of 44 studies were included. Overall, LGBT bias-based victimization, general victimization, bullying, and negative family treatment were significantly associated with suicidal ideation and/or suicide attempts. Associations of discrimination and internalized homophobia and transphobia with suicidal ideation and/or suicide attempts were not significant. No moderation effects were found for sampling strategy. Conclusion: Although overall effect sizes were small, our meta-analytic study shows a clear link between various types of minority stressors and suicidal ideation and suicide attempts among LGBT adolescents and young adults.

Intersecting Structural Oppression and Suicidality Among Black Sexual Minority Male Adolescents and Emerging Adults

This study examined associations between structural racism, anti-LGBTQ policies, and suicide risk among young sexual minority men (SMM). Participants were a 2017-2018 Internet-based U.S. national sample of 497 Black and 1536 White SMM (ages 16-25). Structural equation modeling tested associations from indicators of structural racism, anti-LGBTQ policies, and their interaction to suicide risk factors. For Black participants, structural racism and anti-LGBTQ policies were significantly positively associated with depressive symptoms, heavy drinking, perceived burdensomeness, thwarted belongingness, self-harm, and suicide attempt. There were significant interaction effects: Positive associations between structural racism and several outcomes were stronger for Black participants in high anti-LGBTQ policy states. Structural racism, anti-LGBTQ policies, and their interaction were not significantly associated with suicide risk for White SMM.

Suicidality Among Sexual Minority Adults: Gender, Age, and Race/Ethnicity Differences

INTRODUCTION

Lesbian, gay, and bisexual individuals have elevated suicide risk, but there is little information available about how this risk may vary by gender, age, and race/ethnicity.

METHODS

This study examined past-year suicide thoughts, plans, and attempts among adult respondents to the 2015-2019 National Surveys on Drug Use and Health (pooled N=191,954). Logistic regression was used to examine the differences between lesbian, gay, and bisexual and heterosexual adults for each outcome, once by gender and age category and once by gender and race/ethnicity category, while controlling for core sociodemographic characteristics. Race/ethnicity and age differences were also estimated within sexual identity groups.

RESULTS

Suicide thoughts, plans, and attempts were more common among lesbian, gay, and bisexual adults in almost every age and race/ethnicity category relative to that among corresponding heterosexual adults. In some age and race/ethnicity categories, bisexual women were more likely to report suicidal thoughts than lesbian/gay women. Each outcome decreased significantly across age groups among women of all sexual identity groups and heterosexual men; yet, this age effect was less pronounced among gay and bisexual men. Black women had significantly lower rates of suicidal thoughts and plans than White women in all sexual identity groups.

CONCLUSIONS

In light of consistently elevated rates of suicide thoughts and behaviors, lesbian, gay, and bisexual adults may expressly benefit from enhanced prevention, identification, and treatment of suicide risk. Additional research is needed to assess the associations between sexual identity and suicide mortality as well as to understand the heterogeneity in suicide risk among lesbian, gay, and bisexual youth, particularly by race/ethnicity.

Prospective associations between bi+ minority stressors and internalizing symptoms: The mediating roles of general and group-specific processes

Objective: The prevalence of anxiety and depressive (i.e., internalizing) disorders is higher among bi+ individuals (i.e., individuals with attractions to more than one gender and/or who identify as bisexual or pansexual) compared to both heterosexual and lesbian/gay individuals. Cross-sectional research has demonstrated that stressors unique to bi+ individuals are associated with internalizing symptoms. However, longitudinal research examining these associations and underlying mechanisms is extremely limited. Method: We utilized five waves of data (6 months between waves) from a diverse sample of bi+ individuals assigned female at birth (age 16-32; 29% gender minority; 72.9% racial/ethnic minority) to examine: (a) prospective associations between three bi+ stressors (enacted, internalized, anticipated bi+ stigma) and internalizing symptoms; (b) potential mediating role of rumination in these associations; and (c) potential mediating roles of internalized and anticipated bi+ stigma in associations between enacted bi+ stigma and internalizing symptoms. Results: At the within-person level, when participants experienced more bi+ stressors than usual during a particular wave, they experienced subsequent increases in internalizing symptoms. Increases in rumination mediated these associations. Associations between enacted bi+ stigma and internalizing symptoms were mediated by increases in internalized and anticipated bi+ stigma. Conclusions: Findings indicate that bi+ stressors prospectively predict increases in internalizing symptoms and rumination may play a mechanistic role. Further, findings suggest that internalized and anticipated bi+ stigma may play mechanistic roles in the associations between enacted bi+ stigma and internalizing symptoms. Interventions targeting rumination, internalized stigma, and anticipated bi+ stigma may help to reduce internalizing symptoms among bi+ individuals.

Intersections of Racial Discrimination and LGB Victimization for Mental Health: A Prospective Study of Sexual Minority Youth of Color

Sexual minority youth (i.e., lesbian, gay, and bisexual youth; LGB) of color have multiple minoritized identities, and few studies examine the implications of intersectional minority stressors for their prospective mental health. The current study tested three intersectional hypotheses: the additive hypothesis-racial discrimination and LGB victimization are independently associated with mental health; the multiplicative hypothesis-racial discrimination and LGB victimization interact in to exacerbate their negative association with mental health, and the inuring hypothesis-only racial discrimination or LGB victimization is associated with mental health. Data come from a sample of lesbian, gay, and bisexual youth of color (36% Black, 30% Latino, 26% Multi-racial, 4% Native American, and 3% Asian, Hawaiian, and Pacific Islander) from two U.S. cities, one in the Northeast (77%) and one in the Southwest, who were between ages 15-24 (M = 19) and surveyed four times over three years spaced nine months apart (N = 476; 38% bisexual; 67% free and reduced lunch; and 49% assigned female at birth). The multiplicative hypothesis was supported for depression symptoms, and the additive hypothesis was supported for suicidal ideation. Intersectional minority stressors undermine the mental health of sexual minority youth of color and warrant further investigation.

Sexual Minority Disparities in Health and Well-Being as a Consequence of the COVID-19 Pandemic Differ by Sexual Identity

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has accentuated long-standing population health disparities in the United States. We examined how the pandemic and its social consequences may differentially impact sexual minority adults, relative to heterosexual adults. Methods: Data are from a U.S. national sample of adults (n = 2996; 18.06%) collected from online panels from April to May 2020. We used eight indicators of well-being-mental health, physical health, quality of life, stress, loneliness, psychological distress, alcohol use, and fatigue-to assess the degree to which sexual identity subgroups (i.e., heterosexual, gay/lesbian, bisexual, and "other" sexual minority) varied in retrospective pre- and postpandemic onset indicators of well-being and whether groups varied in their rate of change from pre- and postpandemic onset. Results: The results showed consistent patterns of decline in well-being across sexual identity subgroups, although changes in mental health, physical health, quality of life, stress, and psychological distress were more robust among sexual minority adults in general, relative to heterosexual adults. Adjusted multivariate models testing differences in change in retrospective pre- and postpandemic onset found that well-being among bisexual men and women was most negatively impacted by the pandemic. Conclusion: The COVID-19 pandemic may have distinct health consequences for sexual minority adults in the United States. Our findings support and further legitimize calls for more comprehensive surveillance and cultural responsiveness in emergency preparedness as it relates to sexual minority people and the COVID-19 pandemic.

Family Belongingness Attenuates Entrapment and Buffers Its Association with Suicidal Ideation in a Sample of Dutch Sexual Minority Emerging Adults

Sexual minority emerging adults are more likely to engage in suicidal ideation than their heterosexual counterparts. Experiences of homophobic violence are associated with suicidal ideation. Yet, the specific mechanisms linking homophobic violence to suicidal ideation remain unclear. Entrapment and social belongingness were tested to determine their relevance for understanding the link between homophobic violence and suicidal ideation. A sample of sexual minority Dutch emerging adults (N = 675; ages 18-29, M = 21.93 years, SD = 3.20) were recruited through online platforms and flyers. Homophobic violence was expected to be positively associated with suicidal ideation and entrapment. The association between homophobic violence and suicidal ideation was expected to be indirectly linked through entrapment. We explored whether various sources of social belongingness moderated the path between entrapment and suicidal ideation and whether those sources of social belongingness moderated the indirect effect of homophobic violence on suicidal ideation through entrapment. Results showed that homophobic violence and entrapment were positively associated with suicidal ideation and that family belongingness was negatively associated with suicidal ideation. Homophobic violence and suicidal ideation were not indirectly linked through entrapment. The interaction effect between entrapment and family belongingness was significant, suggesting that, on average, the effect of entrapment on suicidal ideation decreased when family belongingness was high. These results suggest that family belongingness may reduce the association between entrapment and suicidal ideation while adjusting for homophonic violence. Reducing entrapment and improving family belongingness may be useful targets for programs aimed at preventing suicidal ideation among sexual minority emerging adults.

Age, period, and cohort patterns in the epidemiology of suicide attempts among sexual minorities in the United States and Canada: detection of a second peak in middle adulthood

PURPOSE

Sexual minority adults experience fivefold greater risk of suicide attempt, as compared with heterosexuals. Establishing age-specific epidemiological patterns of suicide is a prerequisite to planning interventions to redress the sexual orientation suicide inequity, and such patterns must be carefully interpreted in light of correlated period and cohort effects. We, therefore, combined US and Canadian data (1985-2017) from primary (two pooled multi-year national surveys, N = 15,477 and N = 126,463) and secondary (published, meta-analytic, N = 122,966) sources to separately estimate age, period, and cohort trends in self-reported suicide attempts among sexual minorities.

METHODS

Age- and gender-stratified cross-sectional data were used to infer age and cohort effects. Age-collapsed meta-analyzed data were used to infer period effects among sexual minorities of all genders.

RESULTS

We identified a bimodal age distribution in recent suicide attempts for sexual minorities across genders, though more pronounced among sexual minority men: one peak in adolescence (18-20 years of age for both genders) and one peak nearing mid-life (30-35 years of age for men; 35-40 years of age for women). This pattern was also apparent using recall data within birth cohorts of sexual minority men, suggesting it is not an artifact of birth cohort effects. Finally, we observed decreasing trends in lifetime suicide attempt prevalence estimates for both sexual minorities and heterosexuals, though these decreases did not affect the magnitude of the sexual orientation disparity.

CONCLUSION

In the context of exclusively adolescent-focused suicide prevention interventions for sexual minorities, tailored suicide prevention for sexual minority adults should be pursued throughout the life course.

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.

Age-varying associations between lifestyle risk factors and major depressive disorder: a nationally representative cross-sectional study of adolescents

PURPOSE

Lifestyle risk factors, such as alcohol use, smoking, high body mass index, poor sleep, and sedentary behavior, represent major public health issues for adolescents. These factors have been associated with increased rates of major depressive disorder (MDD). The purpose of this paper is to investigate critical peaks in the prevalence of MDD at certain ages and to examine how these peaks might be amplified or attenuated by the presence of lifestyle risk factors.

METHODS

A nationally representative sample of adolescents aged 11-17 years old (n = 2967) and time-varying effect models were used to investigate the associations between lifestyle risk factors and the prevalence of MDD by sex.

RESULTS

The estimated prevalence of MDD significantly increased among adolescents from 4% (95% CI 3-6%) at 13 years of age to 19% (95% CI 15-24%) at 16 years of age. From the age of 13, males were significantly less likely to have a diagnosis of MDD than females with the maximum sex difference occurring at the age of 15 (OR 0.24, 95% CI 0.13-0.47). All lifestyle risk factors were at some point significantly associated with MDD, but these associations did not differ by sex, except for body mass index.

DISCUSSION

These findings suggest that interventions designed to prevent the development of depression should be implemented in early adolescence, ideally before or at the age of 13 and particularly among young females given that the prevalence of MDD begins to rise and diverge from young males. Interventions should also simultaneously address lifestyle risk factors and symptoms of major depression.

Suicide Attempt Rates and Associations with Discrimination Are Greatest in Early Adulthood for Sexual Minority Adults Across Diverse Racial and Ethnic Groups

Purpose: The study purpose was to investigate differences in past 5-year suicide attempts among racially/ethnically diverse sexual minority (SM) and heterosexual adults across the life course and examine the association of discrimination with past 5-year suicide attempts among SM adults. Methods: Using nationally representative data collected from 2012 to 2013, we assessed differences in age-varying prevalence of past 5-year suicide attempts among Black, Hispanic, and White SM and heterosexual adults (ages 18-60). We tested whether the association between discrimination and suicide attempts differed by race/ethnicity among SM adults. All secondary data analyses were approved by the Institutional Review Boards of The Pennsylvania State University and University of Maryland. Results: Compared with heterosexual adults of any race/ethnicity, SM adults exhibited elevated suicide attempt rates until the late twenties when prevalence for Black and Hispanic SM adults declined. Disparities persisted into the mid-40s for White SM adults. Among SM adults of all races/ethnicities, the relationship between SM discrimination and suicide attempts was strongest between ages 18 and 25. For SM adults reporting SM discrimination, odds of suicide attempts were 3.6 times higher for White SM adults and 4.5 times higher for Black and Hispanic SM adults, relative to same-race/ethnicity SM adults who did not report SM discrimination. The effect of SM discrimination was robust among Black and Hispanic SM young adults even when accounting for racial/ethnic discrimination. Conclusions: SM adults of all racial/ethnic groups demonstrated disparities when contrasted with heterosexual adults of any race/ethnicity, although ages characterized by heightened prevalence rates of suicide attempts differed by race/ethnicity. Early adulthood is a critical period for intervention seeking to disrupt the association between SM discrimination and suicide attempts.

Associations of Discrimination, Suicide Ideation Severity and Attempts, and Depressive Symptoms Among Sexual and Gender Minority Youth

We examined the unique associations among discrimination, suicidal thoughts, suicide attempts, and depressive symptoms in a sample of sexual and gender minority (SGM) youth as well as interpersonal mediators of these associations. Participants included 94 SGM youth (M_age = 18; SD = 2.88) recruited from SGM-specific drop-in centers. We used mediation analyses to test the mediating effects of perceived burdensomeness and thwarted belongingness on the associations between discrimination and suicidal ideation, suicide attempts, and depressive symptoms, accounting for childhood trauma and sociodemographic variables (age, gender identity, race, and sexual orientation). Within our nonclinical community sample of SGM youth, 49% reported a lifetime suicide attempt, 84% reported current suicide ideation, and 82% reported current depressive symptoms. Experiencing discrimination was associated with greater likelihood of suicide attempts and depressive symptoms, and greater perceived burdensomeness and thwarted belongingness, over and above the effects of childhood trauma and sociodemographic variables. Discrimination was indirectly associated with greater depressive symptoms through perceived burdensomeness and thwarted belongingness, and with greater severity of suicidal ideation through perceived burdensomeness. Findings suggest clinicians should assess for discrimination and include a focus on perceived burdensomeness and thwarted belongingness as targets of intervention for suicide and depression.

Sexual Orientation Differences in Alcohol Use Disorder Across the Adult Life Course

INTRODUCTION

Sexual orientation‒related disparities in alcohol use disorder are well-established. Yet, the degree to which sexual orientation differences in alcohol use disorder vary across the life course is poorly understood. There is also a limited understanding of how exposure to minority stressors and their relationship with alcohol use disorder vary as a function of age.

METHODS

Using nationally representative data collected in 2012-2013, authors used sex-stratified time-varying effect models to estimate age-specific prevalence rates of alcohol use disorder among heterosexual and sexual minority adults aged 18-60 years (N=28,090). Among sexual minority adults (n=1,050), authors also assessed age-specific associations between exposure to lesbian, gay, and bisexual‒related discrimination and alcohol use disorder. Analyses were conducted in 2019.

RESULTS

Gay and bisexual male participants aged 18-45 years demonstrated the highest prevalence rates of alcohol use disorder (e.g., >45% at age 25 years), whereas lesbian, gay, and bisexual female participants were most likely to meet the criteria for alcohol use disorder between ages 45 and 55 years. Sexual minority adults who experienced discrimination in the past year had greater odds of alcohol use disorder between ages 23 and 34 years and again from ages 42 to 53 years; the association between discrimination and alcohol use disorder was strongest among sexual minority men.

CONCLUSIONS

Sexual orientation-related disparities in alcohol use disorder are dynamic across the life course and point to critical times for screening and intervention. Developmental perspectives of sexual minority health inequities demand focused research attention as findings will help to identify strategies for promoting sexual minority health at distinct points in the life course.

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.

Associations between sexual orientation discrimination and substance use disorders: differences by age in US adults

PURPOSE

Sexual minorities are at heightened risk for substance use disorders (SUDs). Discrimination based on sexual orientation may be an important factor in this increased risk, but differences across age have not been systematically examined. We examined age-varying associations of sexual orientation discrimination with alcohol use disorder (AUD), tobacco use disorder (TUD), and drug use disorder (DUD).

METHODS

We used data from US participants aged 18-50 years who reported non-heterosexual identity, attraction, or behavior (N = 2375) in a nationally representative survey. We examined the prevalence of sexual orientation discrimination across age and its salience as a risk factor for AUD, TUD, and DUD for gay/lesbian, bisexual, and heterosexual identifying individuals using time-varying effect modeling.

RESULTS

Sexual orientation discrimination was most prevalent in early young adulthood but was positively associated with greater odds of AUD, TUD, and DUD only at later ages. We found statistically significant associations at ages 24.5-40.0 for AUD, ages 32.5-42.9 for DUD, and ages 39.3-43.2 for TUD. For example, discrimination at age 30 was associated with 2.1 times greater odds of AUD (95% CI 1.3, 3.3) compared to those who reported no discrimination at that age. Discrimination at age 35 was associated with 2.8 times greater odds of DUD (95% CI 1.2, 6.6) relative to no discrimination.

CONCLUSIONS

Sexual orientation discrimination is significantly associated with SUDs and risk varies across age. Thus, age should be considered in the development of prevention and treatment of AUD, TUD, and DUD, particularly for sexual minorities.

Scalar-on-function regression for predicting distal outcomes from intensively gathered longitudinal data: Interpretability for applied scientists

Researchers are sometimes interested in predicting a distal or external outcome (such as smoking cessation at follow-up) from the trajectory of an intensively recorded longitudinal variable (such as urge to smoke). This can be done in a semiparametric way via scalar-on-function regression. However, the resulting fitted coefficient regression function requires special care for correct interpretation, as it represents the joint relationship of time points to the outcome, rather than a marginal or cross-sectional relationship. We provide practical guidelines, based on experience with scientific applications, for helping practitioners interpret their results and illustrate these ideas using data from a smoking cessation study.
