Objective: To compare the prevalence and trajectories of risky health behaviors in sexual minority (SM; lesbian/gay/bisexual/questioning/asexual) versus heterosexual undergraduates across their first year of post-secondary. Participants: First-year undergraduates (N = 704, M[subscript age] = 17.97 years, 24% SM) from a midsized Canadian…

This study examined how schools prioritize ten key health concerns among their student populations over time and whether schools' prioritization of alcohol and other drug use (AODU) corresponds to students' substance use behaviours and cannabis legalization as a major policy change.

The aim of this study was to determine if adolescents' scores on a 2-item underage alcohol use screener predict risky consequences of past-year alcohol use and other health risk behaviors in a nonclinical, school-based sample of adolescents. A predominantly minority sample of 756 middle and high school students completed in-school tablet-based…

The Youth Risk Behavior Survey (YRBS) is an epidemiologic surveillance system that was established by the U.S. Centers for Disease Control and Prevention (CDC) to help monitor the prevalence of behaviors that not only influence youth health, but also put youth at risk for the most significant health and social problems that can occur during…
