The relationship of alcohol use and physical activity from an ecologic perspective.

PURPOSE: To determine the predictors of alcohol use (AU) and their relationship to physical activity (PA) among adolescents and to examine differences among groups using an ecologic model. DESIGN AND METHODS: Cross sectional secondary analysis of 11,432 adolescents (51% 8th and 49% 10th graders). RESULTS: Attitude, perception of risk, and academic performance were the strongest predictors of AU. PA did not moderate, but it had a positive influence on AU in 10th graders. Differences were observed among groups. PRACTICE IMPLICATIONS: Nurses can address individual and school factors in an effort to decrease AU and guide nurses in creating an individualized plan.
