Victimization as a mediator in the relationship between sexual orientation and adolescent alcohol use

Trends in substance use among sexual minority adolescents in South Korea

PURPOSE

Substance use, that is of cigarettes, alcohol and chemical inhalants, is a major contributor to health-compromising behaviors and the related consequences among adolescents around the world. The purpose of this paper is to examine trends in this phenomenon in South Korea among sexually active adolescents who reported sexual minority behaviors as compared to their heterosexual (HS) peers.

DESIGN AND METHODS

This study used data from the annual web-based survey called Korea Youth Risk Behavior Survey in 5-year intervals: 2006, 2011, and 2016. From 2017, the questions regarding the gender of sex partners were excluded from the survey, thus no data is available for sexual minorities after 2016. Selected data (Unweighted n = 10,029) was used to assess whether substance use increased, decreased, or remained unchanged among adolescents who reported same-sex (SS) behaviors and bisexual (BS) behaviors compared to their peers reporting HS behaviors. Demographic variables included age and assigned gender. Substances referred to are cigarettes, alcohol, and chemical inhalants. Logistic regression models were sex-stratified according to assigned gender. Trend analyses were carried out to examine disparities in substance use among sexually active adolescents across the three survey years.

RESULTS

Across the three survey years, cigarette use, alcohol use, and problematic drinking declined among all sexually active youths, but there were some differences among the subgroups. In 2016, SS girls were more likely to use cigarettes than HS girls. The prevalence of alcohol use and problematic drinking among BS girls was relatively higher than among girls who exhibited either HS or SS behaviors. Inhalant use was very high among both boys and girls with SS and BS behaviors.

PRACTICE IMPLICATIONS

The findings of the study reveal disparities in substance use between sexual minority and heterosexual adolescents in South Korea. This creates an alarm for collecting data separately for sexually diverse youth in future Korean national surveys with a goal of reducing substance use among all adolescents.

Intersectional stigma subgroup differences in unhealthy drinking and disordered marijuana use among Black and Latino cisgender sexual minority young men

BACKGROUND

We investigated associations of intersectional stigma subgroups with alcohol and marijuana use among Black and Latino sexual minority young men. Subgroups included Minimal Stigma (low to no stigma), Select Social Stigma (occasional stigma in social relationships), Multiform Heterosexism (internalized and interpersonal heterosexism from family/friends), Multiform Racism (racism across diverse contexts), Compound Stigma (frequent, ubiquitous racism and heterosexism).

METHODS

Cohort of Black and Latino cisgender sexual minority young men (n = 414; baseline ages 16-25) surveyed semiannually 2016-2019. Generalized estimating equations integrated with latent class analysis modeled linear and quadratic age effects and association of stigma subgroups with past 6-month alcohol use, marijuana use, unhealthy drinking, and marijuana use disorder symptoms.

RESULTS

All past 6-month substance use peaked between ages 21-23 years old. Across all ages and relative to Minimal Stigma, odds of drinking were higher in every subgroup and highest in Compound Stigma (OR=2.72, 95% CI 1.17-6.35); unhealthy drinking was higher in every subgroup and highest in Multiform Heterosexism (β = 3.31, 95% CI 1.92-3.89); marijuana use disorder symptoms were higher in most subgroups and highest in Compound Stigma (β = 1.30, 95% CI 0.76-1.85). Marijuana use odds did not differ among groups.

CONCLUSION

By examining intersectional stigma subgroups, we identified subgroups for whom substance use was elevated during a development period when use tends to be highest. Young men experiencing stigma patterns characterized primarily by heterosexism or heterosexism together with racism may be especially at risk for developing unhealthy drinking behaviors and marijuana use disorder symptoms.

Disparities in alcohol use and heavy episodic drinking among bisexual people: A systematic review, meta-analysis, and meta-regression

BACKGROUND

Alcohol consumption is more prevalent among sexual minorities than among heterosexuals; however, differences between minority sexual orientation groups are understudied. This systematic review and meta-analysis aimed to summarize existing evidence on the prevalence of alcohol use among bisexual people compared to their lesbian/gay and heterosexual counterparts.

METHODS

A systematic review of literature from 1995 to May 2020 was performed using Medline, PsycInfo, and Embase (OVID), Scopus, CINHAL and LGBT Life (EBSCO), combining keywords for bisexuality and alcohol use. Peer-reviewed publications that reported quantitative data on alcohol use among bisexual people were included. A random-effects model was used to pool the prevalence of two outcomes: any alcohol use and heavy episodic drinking (HED). Subgroup analysis and random-effects meta-regression were used to explore heterogeneity.

RESULTS

Of 105 studies eligible for data extraction, the overall prevalence of alcohol use was higher among bisexuals compared to lesbian/gay and heterosexual people. For example, the prevalence of past-month HED was 30.0% (28.2, 31.8) among bisexual people versus 25.5% (23.8, 27.2) among lesbian/gay and 21.3% (19.6, 23.0) among heterosexual individuals. Pooled odds ratio estimates showed that bisexual people were more likely to report alcohol use and HED compared to their counterparts. Gender was a significant effect modifier in meta-regression analysis, with greater disparities among women than among men.

CONCLUSIONS

These results highlight the need for additional research to understand factors underlying bisexual people's greater risk, and particularly bisexual women, as well as alcohol use interventions that are targeted towards the specific needs of bisexual people.
