Childhood Victimization, Internalizing Symptoms, and Substance Use Among Women Who Identify as Mostly Heterosexual

Health Outcomes of Sexual Minority Women Who Have Experienced Adverse Childhood Experiences: A Scoping Review

Sexual minority women (SMW; e.g., lesbian, bisexual) report higher rates of almost every negative physical health (e.g., asthma, arthritis, cardiovascular disease), mental health (e.g., depression, anxiety), and substance use outcome compared to heterosexual women. Adverse Childhood Experiences (ACEs) have been identified as risk factors for negative health outcomes. Despite this, no study to date has synthesized existing literature examining ACEs and health outcomes among SMW. This gap is important because SMW are significantly more likely than heterosexual women to report every type of ACE and a higher total number of ACEs. Therefore, using a scoping review methodology, we sought to expand understanding of the relationship between ACEs and health outcomes among SMW. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for. Scoping Reviews protocol, we searched five databases: Web of Science, PsycInfo, CINAHL, PubMed, and Embase for studies published between January 2000 and June 2021 that examined mental health, physical health, and/or substance use risk factors and outcomes among adult cisgender SMW who report ACEs. Our search yielded 840 unique results. Studies were screened independently by two authors to determine eligibility, and 42 met full inclusion criteria. Our findings provide strong evidence that ACEs are an important risk factor for multiple negative mental health and substance use outcomes among SMW. However, findings were mixed with respect to some health risk behaviors and physical health outcomes among SMW, highlighting the need for future research to clarify these relationships.

How a "Something Else" Response Option for Sexual Identity Affects National Survey Estimates of Associations Between Sexual Identity, Reproductive Health, and Substance Use

This randomized experiment tested whether the inclusion of a "something else" response option for a question about sexual identity in a national health survey would significantly moderate estimated differences between sexual identity subgroups in terms of various health outcomes, including substance use and reproductive health. We conducted secondary analyses of data from five consecutive years of the National Survey of Family Growth (NSFG; 2015-2019), where two large national half-samples were randomly assigned to receive one of two different versions of a question about sexual identity (a four-category version that included a "something else" response option or a three-category version omitting this option). We focused on national estimates of differences between subgroups defined by sexual identity. Multivariable models indicated that the estimated subgroup differences changed in a statistically significant fashion when using the four-category version of the sexual identity question for several measures, including 16% of male measures (household size, past-year cigarette use, and past-year illicit drug use) and 15% of female measures (wanting a/another child, ever had a sexually transmitted disease, and past-year marijuana use). The absence of a "something else" response option for questions about sexual identity in national health surveys may cause respondents to select options that do not accurately describe their identities, and this can have a significant effect on national estimates of differences between sexual identity subgroups in terms of selected health outcomes.

Mental health and substance use among sexual minority women who report childhood sexual abuse: A systematic literature review

OBJECTIVE

A growing body of literature provides evidence that sexual minority women (SMW; e.g., lesbian, bisexual) are at greater risk of negative mental health and substance use outcomes than are heterosexual women. While minority stress may partially explain these disparities, it does not fully account for them. Therefore, it is necessary to identify how other risk factors (i.e., childhood sexual abuse [CSA]) contribute to SMW's increased risk of negative mental health and substance use outcomes.

METHOD

We conducted a systematic literature review to identify and synthesize the state of knowledge about CSA and mental health and substance use outcomes among SMW. Two independent reviewers screened 347 articles identified in searches of five databases (Web of Science, PsycInfo, CINAHL, PubMed, and Embase). Eligible articles were peer-reviewed, reported quantitative or mixed methods results focused on mental health or substance use outcomes among adult SMW with a history of CSA.

RESULTS

Twenty-four papers were included in the review. Findings clearly show that SMW report higher rates of CSA than heterosexual women. Findings also suggest that CSA may mediate the relationship between minority sexual identity and some negative outcomes.

CONCLUSIONS

Future studies should include minority stress factors, a broader range of mental health outcomes (apart from substance use and suicide), and more nuanced measures of CSA. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The New Genetic Evidence on Same-Gender Sexuality: Implications for Sexual Fluidity and Multiple Forms of Sexual Diversity

In September of 2019, the largest-ever (N = 477,522) genome-wide-association study of same-gender sexuality was published in Science. The primary finding was that multiple genes are significantly associated with ever engaging in same-gender sexual behavior, accounting for between 8-25% of variance in this outcome. Yet an additional finding of this study, which received less attention, has more potential to transform our current understanding of same-gender sexuality: Specifically, the genes associated with ever engaging in same-gender sexual behavior differed from the genes associated with one's relative proportion of same-gender to other-gender behavior. I review recent research on sexual orientation and sexual fluidity to illustrate how these findings speak to longstanding questions regarding distinctions among subtypes of same-gender sexuality (such as mostly-heterosexuality, bisexuality, and exclusive same-gender experience). I conclude by outlining directions for future research on the multiple causes and correlates of same-gender expression.

Exposure to continuous or fluid theories of sexual orientation leads some heterosexuals to embrace less-exclusive heterosexual orientations

We examined whether heterosexual individuals' self-reported sexual orientation could be influenced experimentally by manipulating their knowledge of the nature of sexual orientation. In Study 1 (180 university students, 66% female) participants read summaries describing evidence for sexual orientation existing on a continuum versus discrete categories or a control manipulation, and in Study 2 (460 participants in a nationally representative Qualtrics panel, 50% female) additionally read summaries describing sexual orientation as fluid versus stable across the life-course. After reading summaries, participants answered various questions about their sexual orientation. In Study 1, political moderates and progressives (but not conservatives) who read the continuous manipulation subsequently reported being less exclusively heterosexual, and regardless of political alignment, participants reported less certainty about their sexual orientation, relative to controls. In Study 2, after exposure to fluid or continuous manipulations heterosexual participants were up to five times more likely than controls to rate themselves as non-exclusively heterosexual. Additionally, those in the continuous condition reported less certainty about their sexual orientation and were more willing to engage in future same-sex sexual experiences, than those in the control condition. These results suggest that non-traditional theories of sexual orientation can lead heterosexuals to embrace less exclusive heterosexual orientations.

Differences in Multimorbidity among Cisgender Sexual Minority and Heterosexual Adults: Investigating Differences across Age-Groups

Objectives: Despite increased risk for chronic disease, there is limited research that has examined disparities in multimorbidity among sexual minority adults and whether these disparities differ by age. Methods: Data were from the 2014-2018 Behavioral Risk Factor Surveillance System. We used sex-stratified multinomial logistic regression to examine differences in multimorbidity between sexual minority and heterosexual cisgender adults and whether hypothesized differences varied across age-groups. Results: The sample included 687,151 adults. Gay, lesbian, and bisexual adults had higher odds of meeting criteria for multimorbidity than same-sex heterosexual adults. These disparities were greater among sexual minority adults under the age of 50 years. Only other non-heterosexual men over the age of 50 years and lesbian women over the age of 80 years were less likely to have multimorbidity than their same-sex heterosexual counterparts. Discussion: Health promotion interventions to reduce adverse health outcomes among sexual minorities across the life span are needed.

Past-year discrimination and cigarette smoking among sexual minority women: investigating racial/ethnic and sexual identity differences

Although findings are mixed, discrimination has been identified as a risk factor for smoking in sexual minority women (SMW; e.g., lesbian and bisexual). We examined associations between past-year discrimination and cigarette smoking among SMW. Using regression analyses we examined associations of past-year discrimination including count of types of discriminatory experiences and attributions of the main reason for discrimination (i.e., sexual orientation, race/ethnicity, gender) with smoking outcomes (e.g., current smoking, nicotine dependence, smoking more cigarettes now than 12 months ago). We conducted exploratory analyses to examine whether race/ethnicity and sexual identity moderated the associations of past-year discrimination with smoking outcomes. The sample included 619 SMW. Most identified as lesbian (74.3%) and non-White (61.1%). SMW who reported a higher count of types of discriminatory experiences (AOR 1.54, 95% CI 1.12-2.12) and any gender-based discrimination in the past year (AOR 4.79, 95% CI 1.39-16.45) reported smoking more cigarettes now than 12 months ago. Associations of other past-year discrimination measures with other smoking outcomes were not significant. Compared to White SMW, any discrimination [B (SD) = 2.56 (0.83)] and a higher count of types of discriminatory experiences in the past year [B (SD) = 0.88 (0.31)] were associated with higher nicotine dependence scores in Black/African American SMW. Past-year discrimination are associated with smoking outcomes in SMW. Black/African American race moderated the associations of any past-year discrimination and a higher count of types of discriminatory experiences with nicotine dependence scores in SMW. Targeted interventions to mitigate the influence of discrimination on smoking among SMW are needed.

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.

Sexual Identity, Adverse Life Experiences, and Cardiovascular Health in Women

BACKGROUND

Adverse life experiences (ALE; eg, discrimination and sexual abuse) may contribute to cardiovascular disease (CVD) risk in sexual minority women (SMW), but few studies have tested whether ALE explain the association of sexual identity with cardiovascular health (CVH) markers in women.

OBJECTIVE

The aim of this study was to examine sexual identity differences in CVH among women and the role of ALE.

METHODS

In the Epidemiologic Study of Risk in Women, we used multinomial logistic regression to assess sexual identity differences (SMW vs heterosexual women [reference group]) in CVH markers (ideal vs poor, intermediate vs poor) using the American Heart Association's Life's Simple 7 metric and the total score. Next, we tested whether the association of sexual identity with the total CVH score was attenuated by traditional CVD risk factors or ALE.

RESULTS

The sample consisted of 867 women (395 heterosexual, 472 SMW). Sexual minority women were more likely to have experienced discrimination (P < .001) and lifetime sexual abuse (P < .001) than heterosexual women. Sexual minority women were also less likely to meet ideal CVH criteria for current tobacco use (adjusted odds ratio, 0.43; 95% confidence interval, 0.24-0.73) or intermediate CVH criteria for body mass index (adjusted odds ratio, 0.60; 95% confidence interval, 0.40-0.92). Sexual minority women had a lower cumulative CVH score (B [SE] = -0.35 [0.14], P < .01) than heterosexual women. This difference was not explained by traditional CVD risk factors or ALE.

CONCLUSIONS

Smoking, body mass index, and fasting glucose accounted for much of the CVH disparity due to sexual identity, but those differences were not explained by ALE. Health behavior interventions tailored to SMW should be considered.

Examination of multilevel domains of minority stress: Implications for drug use and mental and physical health among Latina women who have sex with women and men

There has recently been growing attention and concern in the U.S. on the detrimental drug use and related health conditions impacting diverse sexual minority populations. While some evidence indicates that bisexual women are at increased risk of substance use, little attention has been given to disadvantaged and racial/ethnic minority bisexual women, who are particularly vulnerable to a complexity of stressors and risk. Using data from a 15-year longitudinal study in San Antonio, Texas, the current study examines drug use, incarceration histories, stressful life events, and infections among 206 young adult Mexican-American women who report engaging in sex with both men and women (WSWM) (n = 61) and those indicating having exclusively male sex partners (WSM) (n = 145). A bivariate analysis finds that WSWM experienced more frequent (p = 0.001) and longer total time incarcerated (p = 0.001), as well as exposure to more stressful life events (p = 0.003). WSWM also have higher rates of past 30 day injection drug use (p = 0.026) and related Hepatitis C Virus (HCV) infection (p = 0.001), as well as greater symptomatology associated with depression (p = 0.014), PTSD (p = 0.005), and suicidal ideation (p = 0.036). Findings indicate a significantly elevated risk profile for socio-economically marginalized WSWM. This knowledge is timely and central to policy discourse to develop interventions and health campaigns aimed at reducing and/or preventing further health disparities among this highly susceptible population of minority women.

Research on alcohol and other drug (AOD) use among sexual minority women: A global scoping review

Until the 1980s, the limited research on alcohol and other drug (AOD) use among sexual minority women (SMW) focused on alcohol and used samples recruited from gay bars, resulting in inflated estimates of hazardous drinking. Over the past several decades the number of AOD studies with SMW has increased dramatically. To characterize this literature, we conducted a scoping review to answer the following questions: What do we know, and what are the gaps in research about AOD use among SMW? We searched multiple electronic databases (Medline [PubMed], CINAHL, PsycInfo, and Web of Science) for peer-reviewed research articles about AOD use among adult SMW published between January 1, 2000 and May 31, 2017. After duplicates were removed the search identified 4,204 articles. We reviewed the titles and abstracts and removed articles that did not meet inclusion criteria. We used full-text review of the remaining 229 articles to make a final determination regarding inclusion and we retained 181 articles for review. Although the quantity of AOD research with SMW has grown substantially, the great majority of studies have been conducted in the United States (US) and most focus on hazardous drinking; relatively little research has focused on other drugs. In addition, although there has been marked improvement in theories and methods used in this research, many gaps and limitations remain. Examples are the lack of longitudinal research; reliance on samples that tend to over-represent white, well-educated, and relatively young women; sparse attention to mechanisms underlying the disproportionately high rates of AOD use among SMW; and the absence of intervention research. In general, more high-quality research on SMW's use of AODs is needed, but gaps and limitations are particularly large in non-western countries. Addressing these research gaps and limitations is essential for providing information that can be used to develop more effective prevention and early intervention strategies, as well as for informing policies that can help to reduce risky drinking and drug misuse among SMW.

Concurrent Daily Alcohol and Tobacco Use among Sexual Minority and Heterosexual Women

Background: Studies show that sexual minority women (SMW) report more hazardous alcohol use patterns and higher rates of tobacco use than exclusively heterosexual women. Despite the public health implications of drinking and smoking, especially when they co-occur, little is known about SMW's daily use patterns or the factors that may facilitate concurrent use. Objectives: The present study seeks to identify patterns of daily concurrent alcohol and tobacco use among SMW and heterosexual women, including socio-environmental drinking contexts of concurrent use. Methods: Data come from a community sample of lesbian, bisexual, and heterosexual women (N = 246) who completed up to 84 consecutive days of web-based reports about substance use. Results: Participants reported 4,012 drinking days (24%), 2,019 smoking days (12%), and 769 concurrent drinking and smoking days (5%). No differences were found between SMW and heterosexual women in the proportion of drinking days; however, SMW consumed more drinks on drinking days. SMW also reported a greater proportion of smoking days, more cigarettes smoked on smoking days, and a greater proportion of concurrent drinking and smoking days. Reciprocal daily relationships between alcohol and tobacco use were identified, and these relationships were strongest for bisexual women. Socio-environmental factors-including certain locations, situations, and companions-increased the likelihood of concurrent use for all women; however, few sexual identity differences were found in concurrent use contexts. Importance: Results expand our understanding about daily concurrent alcohol and tobacco use risk among SMW, and potentially inform treatment research to better address the unique experiences of this vulnerable group.

Health Disparities Among Exclusively Lesbian, Mostly Lesbian, and Bisexual Young Women

Purpose: Health disparities have been identified between groups of diverse young sexual minority women (SMW) and heterosexual women. This approach may generate sufficient group sizes for statistical analyses but obscures important differences. Moreover, some young women may not identify as "lesbian" or "bisexual" but somewhere in between. This study examined health and sexual minority identity-specific outcomes among three groups of SMW-women who identify as "exclusively lesbian," "mostly lesbian," and "bisexual." Methods: Participants were 990 young (18-30 years old) SMW (exclusively lesbian: n = 305, mostly lesbian: n = 133, bisexual: n = 552) who completed an online survey, including information about mental and physical health symptoms, hazardous drinking, and identity uncertainty. Those who reported alcohol use in the past 30 days responded to questions about their alcohol use and alcohol-related negative consequences. Results: Controlling for demographic differences, health outcomes varied significantly by identity. Mostly lesbian and bisexual women reported the most depression, anxiety, and physical health symptoms; mostly lesbian women reported the highest levels of hazardous drinking. Among those who reported drinking, mostly lesbian women drank the most frequently and reported the most alcohol-related consequences. Mostly lesbian women reported the most identity uncertainty. Conclusion: Mostly lesbian women were similar to bisexual women on several health outcomes. They appear unique, however, in drinking behavior and identity uncertainty. Collapsing across identities in health research may affect outcomes.

An intersectional approach to examine sleep duration in sexual minority adults in the United States: findings from the Behavioral Risk Factor Surveillance System

OBJECTIVES

Investigate sexual identity differences in sleep duration and the multiplicative effect of sexual identity and race/ethnicity among US adults.

DESIGN

Cross-sectional.

PARTICIPANTS

The sample consisted of 267,906 participants from the Behavioral Risk Factor Surveillance System.

MEASUREMENTS

Sleep duration was categorized as very short (≤4 hours), short (5-6 hours), adequate (7-8 hours), or long (≥9 hours). Sex-stratified multinomial logistic regressions were used to examine sexual identity differences in sleep duration. We then examined sleep duration by comparing sexual minorities to (1) same-race/-ethnicity heterosexuals and (2) White participants with the same sexual identity.

RESULTS

Sexual minority women had higher odds of very short sleep compared to heterosexual women, regardless of race/ethnicity. Black gay men had higher rates of very short sleep but lower rates of long sleep relative to Black heterosexual men. Latino and Asian/Pacific Islander bisexual men reported higher rates of short sleep than their heterosexual counterparts. Black lesbian and other-race bisexual women were more likely to have very short sleep than their heterosexual peers. Black lesbian women also had higher rates of long sleep. Analyses examining racial/ethnic differences by sexual identity found that Black and Latino gay men reported higher rates of very short sleep compared to White gay men. Black bisexual women had higher rates of short sleep duration than White bisexual women.

CONCLUSIONS

More research is needed to understand how to promote sleep health among sexual minorities, particularly racial/ethnic minorities, and the impact of inadequate sleep duration on health outcomes in this population.

Différences en matière de santé mentale selon le statut de minorité sexuelle

Objectif Les individus provenant d’une minorité sexuelle rapportent plus de problèmes de santé mentale que les individus ayant une identité hétérosexuelle. Or, la majorité des recherches canadiennes sur ce sujet ont été réalisées il y a plusieurs années, bien avant les changements culturels et légaux concernant la population lesbienne, gay et bisexuelle. Ces changements culturels, sociaux et légaux ont sans aucun doute influencé le portrait clinique de cette population. Cette étude vise à identifier les différences en santé mentale chez les gens qui sont issus ou non de minorités sexuelles.

Méthode Un échantillon régionalement représentatif d’adultes en Estrie, Québec (n = 10 687) a participé à un sondage téléphonique. Pour ce faire, les participants devaient répondre à des questions concernant leur identité sexuelle et la présence de problèmes de santé mentale incluant la détresse psychologique, la dépression, et de problèmes de surconsommation d’alcool et de drogues.

Résultats Les résultats ont indiqué plusieurs différences significatives entre les individus appartenant à une minorité sexuelle et les individus hétérosexuels. Les différences sont surtout observées lorsque les individus bisexuels ou principalement hétérosexuels sont comparés aux individus hétérosexuels. La majorité de ces différences sont principalement expliquées par les variables de contrôle (l’âge, le niveau d’éducation, le revenu et le fait d’appartenir à une minorité visible).

Conclusions Ces résultats suggèrent l’importance d’atténuer les différences sociodémographiques pour améliorer la santé mentale chez les individus issus d’une minorité sexuelle. Les vulnérabilités spécifiques des individus ayant une identité bisexuelle et principalement hétérosexuelle devraient être davantage considérées.
