Introduction: Sexual minority and/or racial/ethnic minority youth may use alcohol at school as a form of minority stress-based coping. Polyvictimization is particularly prevalent among sexual minority and/or racial/ethnic minority youth and may be a useful proxy measure for minority stressors.

Methods: Data from local administrations of the Youth Risk Behavior Survey were pooled across 42 jurisdiction years (biennially, 2009-2017) and analyzed in 2022, resulting in a sample of 118,052 U.

This paper examines the stability of egocentric networks as reported over time using a novel touchscreen-based participant-aided sociogram. Past work has noted the instability of nominated network alters, with a large proportion leaving and reappearing between interview observations. To explain this instability of networks over time, researchers often look to structural embeddedness, namely the notion that alters are connected to other alters within egocentric networks.

Background: Men who have sex with men (MSM) are at high risk for human papillomavirus (HPV) infection and HPV-related anal cancer. Although a safe and effective vaccine is available to prevent HPV infection, HPV vaccine uptake among young MSM remains low.

Purpose: This pilot randomized controlled trial tested the acceptability, feasibility, and preliminary efficacy of a text messaging-based HPV vaccination intervention for young sexual minority men.

To comprehensively assess asthma disparities and identify correlates in youths at the intersections of sex, sexual identity, and race/ethnicity in the United States. We obtained a diverse sample of youths (n = 307 073) from the Centers for Disease Control and Prevention's Youth Risk Behavior Survey. We pooled data across 107 jurisdiction-years (2009-2017).

Men who have sex with men (MSM) are affected disproportionately by cancers caused by human papillomavirus (HPV). A safe and effective vaccine is available to prevent HPV infection, yet rates of HPV vaccination among young MSM are low. Guided by the Information, Motivation, and Behavioral Skills model, the purpose of this study was to identify young sexual minority men's perspectives on HPV vaccination.

Objective: To expand knowledge of co-occurring alcohol use and disordered eating behaviors (DEB) among sexual minority (ie, nonheterosexual) youth.

Method: Using pooled 2009 to 2015 US Youth Risk Behavior Surveys (322,687 students; 7.3% lesbian, gay, bisexual), multivariable logistic regression models examined the following: (1) associations of age of onset of drinking and past month binge drinking with past year DEB (fasting, diet pill use, purging, steroid use); and (2) effect modification by sexual orientation.

Objectives: To determine how sensitive estimates of lesbian, gay, bisexual, or questioning (LGBQ)-heterosexual youth health disparities are to the presence of potentially mischievous responders.

Methods: We used US data from the 2015 Youth Risk Behavior Survey, pooled across jurisdictions that included a question about sexual identity for a total sample of 148 960 students. We used boosted regressions (a machine-learning technique) to identify unusual patterns of responses to 7 screener items presumably unrelated to LGBQ identification, which generated an index of suspected mischievousness.

Low physical activity (PA), high sedentary behavior (SB), and overweight and obesity have been shown to associate with increased Type 2 diabetes risk among adolescents. We investigated PA, SB, and overweight and obesity among Youth Risk Behavior Survey (YRBS) respondents to determine if non-heterosexual youth may be at increased diabetes risk compared to heterosexual youth. Weighted city and state YRBS data were pooled across 44 jurisdictions biennially from 2009 to 2015, resulting in a sample size of 350 673 students.

Objective: Sexual minority adolescents (SMA) may be at disproportionate risk for misusing prescription psychotropic medications compared to their heterosexual peers. However, generalizable studies specific to this age group are lacking. The current study aimed to describe the prevalence of sexual orientation disparities in prescription drug misuse among a nationally representative sample of adolescents as well as to examine key correlates of misuse.

Background: Guy2Guy (G2G) is the first comprehensive HIV prevention program developed for sexual minority males as young as 14 years old and is delivered nationally via text messaging. Here, we report the results of the pilot randomized control trial.

Methods: G2G was tested against an attention-matched "healthy lifestyle" control (eg, self-esteem).

Purpose: There is a dearth of HIV prevention/healthy sexuality programs developed for adolescent gay and bisexual males (AGBM) as young as 14 years old, in part because of the myriad ethical concerns. To address this gap, we present our ethics-related experiences implementing Guy2Guy, a text messaging-based HIV prevention/healthy sexuality program, in a randomized controlled trial of 302 14- to 18-year-old sexual minority males.

Methods: Potential risks and efforts to reduce these risks are discussed within the framework of the Belmont Report: Respect for persons, beneficence (e.

The Australian medical education system is at a critical juncture in relation to what and how it delivers for Aboriginal and Torres Strait Islander health. Since 2004, three key organisations concerned with medical education have worked to provide a toolkit for implementation of sustainable reform within medical schools. The aim is a medical workforce trained in Indigenous health, and more Aboriginal and Torres Strait Islander doctors, leading to better health for Australia's Indigenous peoples.
