Family psychological factors in relation to children's asthma status and behavioral adjustment at age 4.

The objectives of this study were to determine whether family psychosocial factors influenced asthma development by age 4, and whether family factors and early wheezing illness were associated with behavioral adjustment at age 4. Participants were 98 children enrolled in an intervention study at 9-24 months and followed to age 4. Baseline evaluations assessed infants' respiratory illness severity, family psychosocial characteristics, and parental risk factors for asthma development. Active asthma categorization at age 4 utilized both parent report and objective data. Parents completed the Child Behavior Checklist (CBCL). Caregiver single-parent status, a composite of baseline family stresses, and early wheezing illness severity were associated with active asthma at age 4. The contribution of prenatal smoke exposure and early hospitalization to active asthma varied with racial/ethnic group membership. Maternal mental health and family stresses predicted CBCL scores at age 4, whereas early illness severity and hospitalization were unrelated to CBCL scores. CBCL scores were not elevated for children with active asthma at age 4. Family factors consistent with a negative emotional environment were associated with both active asthma and adjustment problems at age 4, suggesting that both outcomes may be influenced by a common factor.
