The role of the social environment in children and adolescents with asthma.

Rationale: Biopsychosocial models of asthma have been proposed in the literature, but few empirical tests of social factors at various levels of influence have been conducted.

Objectives: To test associations of neighborhood, peer, and family factors with asthma outcomes in youth, and to determine the pathways through which these social factors operate.

Methods: Observational study of youths with asthma (n = 78).
