Area of Science:

  • Pediatric Pulmonology
  • Epidemiology
  • Public Health

Background:

  • Asthma is a significant public health concern in children.
  • Early identification and management are crucial for improving outcomes.
  • Adolescent asthma prevalence and healthcare utilization patterns require further investigation.

Purpose of the Study:

  • To assess the prevalence of diagnosed asthma and wheezing in 13-14 year olds in North Carolina.
  • To evaluate healthcare utilization among asthmatic adolescents.
  • To determine the feasibility of statewide asthma surveillance using the International Survey for Asthma and Allergies in Childhood (ISAAC) questionnaire.

Main Methods:

  • A cross-sectional study involving 1,596 children aged 13-14 years.
  • Utilized the International Survey for Asthma and Allergies in Childhood (ISAAC) questionnaire.

  • Assessed diagnosed asthma, wheezing symptoms, healthcare utilization, and environmental triggers.

    • Main Results:

    • 10% of adolescents reported current diagnosed asthma.
    • 19% reported wheezing without an asthma diagnosis.
    • Frequent wheezing was associated with lower socioeconomic status, African-American ethnicity, and female gender.
    • 30% of diagnosed asthmatics had at least one emergency room visit in the past year.
    • Undiagnosed asthmatics were largely unmedicated.

    Conclusions:

    • The study highlights a substantial burden of asthma in early adolescence.
    • Significant numbers of adolescents experience undiagnosed asthma and associated healthcare needs.
    • Statewide asthma surveillance using the ISAAC questionnaire is feasible and recommended for public health initiatives.
