The network scale-up method (NSUM) is a survey-based method for estimating the number of individuals in a hidden or hard-to-reach subgroup of a general population. In NSUM surveys, sampled individuals report how many others they know in the subpopulation of interest (e.g. "How many sex workers do you know?") and how many others they know…

Venue-based strategies offer effective means of targeting men who have sex with men. Few studies have sought to focus on where younger men congregate and understand risk behaviors that may occur at lower (i.e., community centers) versus higher risk venues. Data from 1,311 young men who have sex with men (YMSM) aged 12- to 24-years-old recruited…

"Abstinence-only" sex education, which is still widely used across the United States, does not prepare students to engage in healthy adult relationships.

Sexual minority youth are more likely to run away from home or experience homelessness, leaving them at increased risk of victimization and negative health outcomes. In this study, the authors use a developmental perspective that considers both vulnerable beginnings in families and the risky trajectories that follow to explore the connections…

The efficacy of sex education has been questioned, as students participate in high rates of unsafe sex after completion. Without exploring various sexual minority (SM) identities (e.g., gay, lesbian, and bisexual) and forms of sex, sex education may be especially unhelpful for SMs by perpetuating the heteronormative (i.e., assuming heterosexuality…
