ABSTRACT
Research sought to identify combinations of risk and protective factors predicting change in physical activity (PA) over one year in high school students. Adolescents (N = 344; M = 15.7 years) participated in a longitudinal study with assessment of demographics, substance use/smoking exposure, height and weight, psychological factors, and PA in 10th and 11th grade. PA participation in 11th grade was greatest for adolescents who engaged in PA and had high sports competence (78%), and least for adolescents who did not engage in or enjoy PA (13%) in 10th grade. Identifying adolescent subgroups at risk for decreasing PA can inform the development of tailored interventions.

The present study tested the indirect effect of home indoor smoking restrictions on adolescent smoking through peer smoking. Based on a bioecological perspective of development, we hypothesized that forbidding indoor smoking would reduce the likelihood of adolescent smoking by decreasing exposure to peer smoking, even when adolescents live with at least one household member who smokes. Participants were 163 adolescents (mean age = 16 years) from a suburban southeastern Pennsylvania community. Participants completed a self-report survey evaluating home indoor smoking restrictions, smoking behavior, peer smoking, alcohol use, and demographics. Structural equation modeling indicated that forbidding smoking indoors was associated with having fewer peers who smoke, which was associated with a lower level of smoking. The indirect effect was significant (beta = -.569, 95% CI -.90 to -.24), offering some preliminary ideas about why home indoor smoking restrictions reduce the risk of adolescent smoking. However, the nature and stability of these effects on adolescent smoking behavior remain to be investigated.
