Statewide adolescent asthma surveillance.
We assessed the prevalence of diagnosed asthma, wheezing, healthcare utilization, and environmental triggers in children ages 13-14 years, and evaluated the feasibility of statewide asthma surveillance in North Carolina. A cross-sectional study (N = 1,596) was conducted using the International Survey for Asthma and Allergies in Childhood (ISAAC) questionnaire. Ten percent reported current diagnosed asthma. Nineteen percent reported wheezing symptoms with no diagnosis of asthma. Children with frequent wheezing were more likely to be poor, African-American, and female. Thirty percent of diagnosed asthmatics made 1 or more emergency room visits in the last year. Undiagnosed asthmatics were unmedicated. These results highlight the magnitude of the asthma epidemic in early adolescence, and illustrate that statewide surveillance using ISAAC is feasible.
