Objectives. We examined perpetration of bullying among youths in vulnerable groups relative to youths in peer groups not categorized as vulnerable. Methods. Data were collected in 2013 from a large school-based survey of adolescents conducted in Minnesota (n = 122 180). We used the v2 test and logistic regression to compare measures of perpetration of physical and relational bullying, as well as experiences of victimization and perpetration (or both), across categories of sexual orientation, weight status, and disability status. Results. Rates of physical and relational bullying perpetration were significantly higher among youths in vulnerable groups than among those not in vulnerable groups. With respect to context of victimization experiences, young men and women from vulnerable groups were overrepresented in the group comprising both perpetrators and victims. For example, odds of being both a perpetrator and a victim were 1.41 to 3.22 times higher among gay, lesbian, and bisexual youths than among heterosexual youths. Conclusions. Vulnerable youths, who are prone to peer harassment, may also act as perpetrators of bullying. Prevention strategies should address the particular needs of these populations; targeted programming may be appropriate. [ABSTRACT FROM AUTHOR]

Objectives. We assessed disparities in weight and weight-related behaviors among college students by sexual orientation and gender. Methods. We performed cross-sectional analyses of pooled annual data (2007–2011; n = 33 907) from students participating in a Minnesota state-based survey of 40 two- and four-year colleges and universities. Sexual orientation included heterosexual, gay or lesbian, bisexual, unsure, and discordant heterosexual (heterosexuals engaging in same-sex sexual experiences). Dependent variables included weight status (derived from self-reported weight and height), diet (fruits, vegetables, soda, fast food, restaurant meals, breakfast), physical activity, screen time, unhealthy weight control, and body satisfaction. Results. Bisexual and lesbian women were more likely to be obese than heterosexual and discordant heterosexual women. Bisexual women were at high risk for unhealthy weight, diet, physical activity, and weight control behaviors. Gay and bisexual men exhibited poor activity patterns, though gay men consumed significantly less regular soda (and significantly more diet soda) than heterosexual men. Conclusions. We observed disparities in weight-, diet-, and physical activity– related factors across sexual orientation among college youths. Additional research is needed to better understand these disparities and the most appropriate intervention strategies to address them. [ABSTRACT FROM AUTHOR]
