Sexual identity differences in high-intensity binge drinking: findings from a US national sample

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.

Changes in Sexual Identity and Associations With Alcohol Use and Depression Among Young Adult Sexual Minority Women

OBJECTIVE

Sexual minority women report more problematic alcohol use and depression than heterosexual women. Despite evidence that sexual identity can change over time, most studies treat it as a static construct. As a result, little is known about the extent to which changes in sexual identity influence alcohol use and depression. The current study examined (a) changes in sexual identity over 36 months, (b) the associations between the number of changes in sexual identity and measures of alcohol use (typical weekly alcohol consumption, peak drinking, and alcohol-related consequences) and depression at the final assessment, and (c) baseline sexual identity as a moderator of the associations.

METHOD

The analyses used four waves of data from a national U.S. sample of sexual minority women ages 18-25 (n = 1,057).

RESULTS

One third (34%) of participants reported at least one change in sexual identity over the course of the study. The number of changes in sexual identity was positively associated with typical weekly alcohol consumption and depression but was not significantly associated with peak drinking or alcohol-related consequences. None of the associations were moderated by baseline sexual identity.

CONCLUSIONS

These findings provide additional evidence that sexual identity continues to change over time for a sizeable proportion of young adult sexual minority women and these changes are relevant to their health and well-being.

Stressors and Drinking in Sexual Minority Women: The Mediating Role of Emotion Dysregulation

Sexual minority women are at elevated risk for exposure to stressors (both traumatic and discriminatory) and have higher rates of alcohol consumption and problems. The psychological mediation framework (Hatzenbuehler, 2009) suggests that both general (e.g., traumatic events to which minorities and nonminorities may be exposed) and minority-group-specific (e.g., discrimination) stressors contribute to psychopathology through mediators such as emotion dysregulation. Guided by this framework, the present study longitudinally examined the relationship between stressors and problematic drinking outcomes (i.e., binge drinking and alcohol-related problems), as mediated by emotion dysregulation, in sexual minority women (SMW). It addressed two research questions: (1) whether stressors longitudinally predict problematic drinking outcomes in SMW, as mediated by emotion dysregulation, and (2) for which specific forms of stressor (i.e., traumatic events and/or discrimination) this mediational relationship is present. Young adult women (N = 1057) who identified as lesbian or bisexual completed annual measures of daily heterosexism, traumas, and drinking outcomes for four years, and completed a measure of emotion dysregulation during the third year of data collection. We found an indirect relationship between discrimination and problematic drinking outcomes via emotion dysregulation. These findings are consistent with the psychological mediation framework (Hatzenbuehler, 2009) and suggest that SMW group-specific processes such as discrimination may be especially important in conferring risk for problem drinking via emotion dysregulation. Clinicians are advised to assess unique stressors faced by SMW and their potential contribution to problematic drinking outcomes, and to target emotion dysregulation in alcohol treatments.

Alcohol use and binge drinking among men who have sex with men in China: Prevalence and correlates

BACKGROUND

Both alcohol use/misuse and HIV incidence are increasing among men who have sex with men (MSM) in China. Little is known about predictors of alcohol use/misuse.

METHODS

An online nationwide sample (n = 1100) of MSM from mainland China was recruited between 2014 and 2015. The study objective was to examine the prevalence of a history of alcohol use and frequency of binge drinking in the previous 6 months in this population and assess their relationship with psychological and public health issues.

RESULTS

Nearly 62.1% of respondents reported a history of alcohol use; 30.7% were current infrequent binge drinkers; and 13.6% were current frequent binge drinkers. Adjusted logistic models showed that MSM who reported a history of alcohol use were more likely to report drug use in the previous 6 months (AOR = 1.67); higher levels of internalized homophobia (AOR = 1.49); and partial or full disclosure of their sexual orientation (AOR = 1.46). MSM engaging in current frequent binge drinking were more likely to report female sexual partners (AOR = 2.04) and drug use (AOR = 1.61) in the previous 6 months; higher levels of sexual sensation seeking (AOR = 1.68); and higher levels of homosexual stigma (AOR = 1.69). MSM who reported being unsure of their HIV status were less likely to be current frequent binge drinkers (AOR = 0.46).

CONCLUSIONS

A high prevalence of a history of alcohol use and binge drinking exists among Chinese MSM. Strategies that target alcohol use/misuse in this population are needed.

Sexual Orientation-Related Disparities in High-Intensity Binge Drinking: Findings from a Nationally Representative Sample

Purpose: The purpose of this study was to assess sexual orientation differences in high-intensity binge drinking using nationally representative data. Methods: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions III (N = 36,309), a nationally representative sample of U.S. adults collected in 2012-2013. Sex-stratified adjusted logistic regression models were used to test sexual orientation differences in the prevalence of standard (4+ for women and 5+ for men) and high-intensity binge drinking (8+ and 12+ for women; 10+ and 15+ for men) across three dimensions of sexual orientation: sexual attraction, sexual behavior, and sexual identity. Results: Sexual minority women, whether defined on the basis of sexual attraction, behavior, or identity, were more likely than sexual majority women to engage in high-intensity binge drinking at two (adjusted odds ratios [aORs] ranging from 1.52 to 2.90) and three (aORs ranging from 1.61 to 3.27) times the standard cutoff for women (4+). Sexual minority men, depending on sexual orientation dimension, were equally or less likely than sexual majority men to engage in high-intensity binge drinking. Conclusion: This study is the first to document sexual orientation-related disparities in high-intensity binge drinking among adults in the United States using nationally representative data. The results suggest that differences in alcohol-related risk among sexual minority individuals vary depending on sex and sexual orientation dimension.

Bisexual Women's Reports of Descriptive Drinking Norms for Heterosexual, Bisexual, and Lesbian Women

Bisexual women drink more than lesbian and heterosexual women. However, few studies have examined factors that influence drinking among bisexual women. Although descriptive drinking norms are strong predictors of drinking, little research has examined how drinking norms influence alcohol use for bisexual women. The present study examined bisexual women's reports of descriptive drinking norms for bisexual, lesbian, and heterosexual women, and associations with their own frequency of alcohol consumption, quantity, binge drinking, and hazardous alcohol use. Participants were 179 self-identified bisexual women between 18 and 30 years old who reported past 30-day drinking. Participants perceived more frequent alcohol use for bisexual and heterosexual women as compared to lesbian women. Further, participants perceived higher alcohol quantity for heterosexual as compared to lesbian women, but norms for alcohol quantity did not differ between bisexual women and other groups. Descriptive drinking norms about bisexual women were positively related to participants' frequency of alcohol consumption, binge drinking, and hazardous alcohol use. In contrast, descriptive drinking norms about heterosexual women were negatively associated with participants' binge drinking and hazardous alcohol use. Findings document the importance of assessing drinking norms separately for bisexual, lesbian, and heterosexual women. Alcohol interventions that include information about drinking norms for bisexual women specifically may be more effective at reducing hazardous drinking.

Sexual Minority Youth Report High-Intensity Binge Drinking: The Critical Role of School Victimization

PURPOSE

To examine standard binge drinking (≥4 drinks for females, ≥5 drinks for males) and high-intensity binge drinking (≥8 drinks for females, ≥10 drinks for males) among heterosexual and sexual minority youth in the US and whether reports of school-based victimization mediate this association.

METHODS

Survey data are from the 2015 Youth Risk Behavior Survey (YRBS; n = 10,839, Mage = 16.07). Logistic regression adjusted for race/ethnicity and age compared rates of standard and high-intensity binge drinking among heterosexual and sexual minority youth and whether experiences of school-based victimization mediated this association. Effects were tested in full sample and sex-stratified models.

RESULTS

Lesbian and bisexual girls and girls with male and female partners were more likely than heterosexual girls to report standard rates of binge drinking. Lesbian girls and girls reporting male and female sexual partners were more likely than heterosexual girls to report high-intensity binge drinking in the past 30 days. Compared with heterosexual boys, gay boys were significantly less likely to participate in high-intensity binge drinking. School-based victimization mediated all significant associations between sexual minority status and standard and high-intensity binge drinking, with the exception of lesbian girls.

CONCLUSION

Lesbian and behaviorally bisexual girls have elevated risk for high-intensity binge drinking relative to heterosexual girls. Findings point to the importance of policies that reduce school-based victimization as these experiences are associated with higher rates of standard and high-intensity binge drinking among sexual minority girls.
