Alcohol use at the intersection of sexual orientation and gender identity in a representative sample of youth in Colorado

Adolescent Substance Use at the Intersection of Sexual Orientation and Gender Identity

BACKGROUND

Substance use in adolescence is associated with multiple negative outcomes. Lesbian, gay, or bisexual or transgender or nonbinary (TNB) youth, and those who question their sexual orientation or gender, are more likely to engage in substance use than straight or cisgender youth. However, the extant literature largely considers sexual orientation and gender identity independently. Accordingly, this study examines the associations between the intersectional identities of sexual orientation and gender and substance use to identify those with the greatest need for prevention interventions.

METHODS

Data were from 36 504 high school students aged 14 to 18 years (mean = 15.7, SD = 1.18) enrolled in the 2019 Healthy Kids Colorado Survey using a statewide stratified random sampling design. Logistic regression models examined the associations between intersectional sexual orientation and gender on marijuana use, prescription drug misuse, and polysubstance use, as well as depression and violence victimization (eg, forced sex, partner violence).

RESULTS

Adjusted odds of substance use for sexual and gender minority youth varied by intersectional identity and substance. The largest effect sizes were seen for prescription drug misuse, especially among those questioning their gender and sexual orientation and heterosexuals either questioning their gender or who identified as TNB. Effect sizes for marijuana use and polysubstance use were highest for TNB and heterosexual participants. Depression and violence victimization were significantly associated with each substance use outcome.

CONCLUSIONS

Interventions to reduce substance use in these populations may benefit from targeted interventions for youth with different intersectional identities, and a focus on violence prevention and depression screening and treatment.

Substance use prevalence, patterns, and correlates in transgender and gender diverse youth: A scoping review

Transgender and gender diverse (TGD) adults are at elevated risk of problematic substance use. While understanding substance use disparities in TGD youth is crucial for informing early preventions, there is no known synthesis of prevalence and correlates of substance use in TGD youth. The objectives of this study were to: 1) describe the prevalence and patterns of substance use in TGD youth, 2) identify and evaluate potential correlates of substance use, and 3) report the strengths and limitations of the current literature in recommendation of future steps. A PRISMA-guided systematic search was conducted to identify 55 studies that reported prevalence, patterns, or correlates of substance use in TGD youth aged 10-24 years; were published in the English language; and followed a quantitative design. Fifty-four (98.18%) studies examined prevalence and patterns, 23 (41.82%) examined correlates, and 12 (21.82%) examined moderators and mediators of substance use in TGD youth. Findings suggest TGD youth exhibit a moderate-to-high prevalence of recent substance use, including alcohol (23-31%), binge drinking (11-59%), cigarettes (10-59%), e-cigarettes (17-27%), and marijuana (17-46%). Additionally, results supported that greater victimization experiences, including those related and unrelated to being a gender minority, were associated with increased substance use risk. Few studies examined polysubstance use, resilience, and protective factors, or considered TGD subgroup differences, which we recommend in future research. Further, we recommend improving population-based surveys to better capture gender identity and related experiences.

Binge drinking disparities by gender identity, race, and ethnicity in California secondary schools

Our objective was to estimate disparities in binge drinking among secondary school students in California at the intersection of gender identity, race, and ethnicity, without aggregating racial and ethnic categories. We combined two years of the Statewide middle and high school California Healthy Kids Survey (n=951,995) and regressed past month binge drinking on gender identity (i.e., cisgender, transgender, or not sure of their gender identity), race (i.e., white, American Indian or Alaskan Native, Asian, Black or African American, Native Hawaiian or Pacific Islander, or multiracial), and ethnicity (i.e., Hispanic/Latinx or non-Hispanic/Latinx), and their interaction. Transgender students had greater odds of reporting past month binge drinking than cisgender students, with greater magnitudes among students with minoritized racial or ethnic identities compared to non-Hispanic/Latinx white students. For example, among non-Hispanic/Latinx white students, transgender students had 1.3 times greater odds (AOR=1.30, 95% CI=1.17-1.55), whereas among Hispanic/Latinx Black or African American students, transgender students had 5.3 times greater odds (AOR=5.33, 95% CI=3.84-7.39) of reporting past month binge drinking than cisgender students. Transgender adolescents, particularly those with minoritized racial or ethnic identities, may be at disproportionate risk of binge drinking. Interventions that address systemic racism and cisgenderism from an intersectional perspective are needed.

Reward Responsiveness, Learning, and Valuation Implicated in Problematic Pornography Use — a Research Domain Criteria Perspective

Purpose of Review

Problematic pornography use (PPU) describes a pattern of behavior characterized by excessive time spent using or thinking about pornography and continued use despite negative consequences. To help advance the understanding of transdiagnostic underlying psychological and neurobiological mechanisms in PPU, we aim to review existing evidence on these mechanisms focusing on positive valence systems within the transdiagnostic Research Domain Criteria (RDoC) framework.

Recent Findings

Reward anticipation processes seem to be increased in individuals with PPU symptoms when they anticipate sexual stimuli compared with other rewards. Studies further suggest that the initial neural and attentional responses to sexual rewards compared with different control stimuli are also increased in individuals with PPU symptoms, as are conditioned responses in sexual reward learning paradigms. Sexual reward valuation studies point towards an increased neural value differentiation with increasing PPU symptoms.

Summary

The current state of evidence indicates that positive valence systems are altered in persons with PPU. This framework of organizing evidence may aid in elucidating PPU development and maintenance as well as planning future studies.
