Patterns of Marijuana Use and Physical Health Indicators Among Canadian Youth

The current study adds to our growing understanding of the health of Canadian youth with differing marijuana use trajectories by examining how marijuana use fre- quency is related to physical health indicators in ado- lescence and young adulthood. We extend past research by examining how trajectories of marijuana use are related to multiple physical health indicators; subjective health, health-promoting behaviours, body mass index, serious injuries and sexual risk behaviours.

Adolescent Patterns of Peer Victimization - Concurrent and Longitudinal Health Correlates

We examine how heterogeneity in adolescent experiences of peer victimization impact health in adolescence and young adulthood. We include multiple indicators of mental health - internalizing symptoms (i.e., depressive and anxiety symptoms), externalizing symptoms (i.e., attention deficit hyperactivity disorder (ADHD) symptoms, oppositional defiant disorder (ODD) symptoms, and conduct problems), and substance use (i.e., smoking, heavy drinking, marijuana and illicit drug use). We also use multiple measures of physical health - subjective health (i.e., physical symptoms and physical self-concept), health-promoting behaviors (i.e., physical activity, healthy eating practices, and sleep duration and problems), and cardiometabolic risks (i.e., BMI waist circumference, and hypertension). In examining young adult health, we directly control for earlier (i.e., baseline) symptoms in order account for stability in health over time.
