Objectives:
To present national population-based estimates of the prevalence of parent-reported emotional and/or behavioral problems in children with asthma and the relationship of medical comorbidity and asthma severity with behavior problems.
Design:
Cross-sectional study of the 1988 National Health Interview on Child Health.
Main Outcome Measures:
Parent responses to a checklist of child health conditions were used to assign school-age children (5 to 17 years old) into one of four groups: children without reported chronic conditions; children with asthma alone; children with asthma and additional reported chronic conditions; and children with the same chronic conditions, but without asthma. Parental responses to the Behavior Problem Index (BPI) were used for construction of an overall BPI score, as well as subscale scores. Cross-tabulation and linear and logistic regression were used to determine the relation of the different condition categories to emotional and/or behavioral problems expressed by relative values of the BPI.
Results:
Children with asthma and comorbid conditions had a mean BPI score of 7.3, compared with 5.4 for children without chronic conditions, and all subscale scores, except those for antisocial conduct and immature behavior, were significantly elevated. Using logistic regression to control for confounding variables, children with severe asthma alone had nearly three times the odds (odds ratio, 2.96; 95% confidence interval, 1.22 to 7.17) and children with asthma plus comorbid conditions nearly twice the odds (odds ratio, 1.86; 95% confidence interval, 1.20 to 2.90) of children without chronic conditions to have severe behavior problems.
Conclusions:
Severe asthma and asthma with medical comorbidity represent significant risk factors for emotional and/or behavioral problems. Clinicians caring for children with asthma and their families should be aware of the relationship between asthma and emotional and/or behavioral problems and anticipate that a substantial number of their patients may have mental health services needs.
