Social ecological predictors of physical activity
ABSTRACT:
| Physical inactivity is a leading cause of death in America and smokers are more at risk to be physically inactive. This study examined interrelationships among social ecological variables via classification and regression trees (CART) analyses to form subgroups of individuals based on their level of physical activity. Logistic regressions were compared to CART. Important predictors included neighborhood accessibility, occupational physical activity, sleep, age, neighborhood safety, and previous LTPA. CART had higher classification rates than logistic regressions at six- and 12-months. Different tree structures were found between African Americans and Caucasians. These findings may aid the development of empirically-driven interventions. |
