The prevalence of overweight and obesity in United States children and adolescents was recently reported to be 32 % (Ogden et aI., 2010). Researchers believe that low levels of physical activity are at least partially responsible for prevalence rates, since approximately 60 % ofU.S. children and adolescents do not meet physical activity recommendations (Troiano et aI., 2008). Low income, minority populations in the U.S. experience higher prevalence of obesity and are less physically active compared to their white counterparts (Sallis et aI., 2000; Butcher et aI., 2008; Flegal et aI., 2010). Thus, it is important to address correlates of physical activity (PA) in low income, minority populations in order to determine psychosocial variables upon which to focus physical activity interventions.
