title: Contextual Influences on Weight Status Among Impoverished Adolescents: Neighborhood Amenities for Physical Activity and State Laws for Physical Education Time Requirements.
abstract: OBJECTIVE
  This study examines the relationship between state laws for physical education and neighborhood amenities for physical activity on weight status in adolescents of low socioeconomic status.
  
  
  METHODS
  Data from 2 national data sources: Classification of Laws Associated with School Students (CLASS) and the National Survey of Children's Health (NSCH) were combined and analyzed.
  
  
  RESULTS
  Multinomial regression models found that adolescents in states with strong PE law were associated with a lower odds of being obese [OR = 0.63 (0.41, 0.97)]; however, when PE law and neighborhood amenities were included, only neighborhood amenities were associated with lower odds of obesity, but also greater odds of overweight status.
  
  
  CONCLUSIONS
  This study emphasizes the potential significance of state laws on low SES groups to combat obesity; as well as the potential differential effects of local level factors, and alignment with policy goals for healthy weight.
