Sixty-one low-income, African-American mothers of preschool children with asthma were interviewed about asthma management. Additionally, 15 nurses provided information for a developmental schedule of asthma self-management activities. Most children had been diagnosed with asthma prior to age 18 months. Children participated in asthma management by 20 months, yet their mothers did not expect them to be able to manage their asthma by school age. Mothers expended considerable effort in coordinating asthma management with others. We suggest that asthma education with this population promote developmentally appropriate parent-child partnerships and effective involvement of family members and secondary settings.
