Adolescent risk taking, neighborhood social capital, and health.

Purpose: To assess the roles of a neighborhood measure of social capital, family affluence, and risk taking on adolescent self-rated health.

Methods: This study uses data from the 2384 Canadian students in Grades 9-10 (56.5% female) from the World Health Organization's Health Behavior in School-Aged Children Survey 2001/2002, a nationwide representative sample.

Associations between risk behavior and injury and the protective roles of social environments: an analysis of 7235 Canadian school children.

Objective: The social etiology of adolescent injury remains poorly understood. The Population Health Framework suggests that the etiology of adolescent injury involves interactions between individual risk factors and the natures of adolescent environments. The purpose of this study was to apply this framework to examination of relationships between adolescent risk taking and injury, and the potential modifying effects of supportive home and school environments.
