Design and methods of the National Cooperative Inner-City Asthma Study

Area of Science:

• Environmental Health
• Epidemiology
• Pediatric Pulmonology

Background:

• Inner-city children face significant asthma morbidity.
• Identifying contributing factors is crucial for effective interventions.

Purpose of the Study:

• To describe the design and methods of the Phase I epidemiologic investigation of the National Cooperative Inner-City Asthma Study (NCICAS).
• To identify factors related to asthma morbidity in inner-city children.

Main Methods:

• Enrolled 1,528 children (4-9 years) in eight urban research centers.
• Collected data on symptoms, medical history, healthcare access, psychological health, asthma knowledge, allergen sensitization, and home environment exposures (including secondhand smoke).
• Conducted in-home visits, collected biological samples (urine for cotinine, blood), and performed spirometry for lung function.

Main Results:

• Detailed baseline data collected on a large cohort of inner-city children with asthma.
• Follow-up assessments at 3, 6, and 9 months included symptom tracking and healthcare utilization.
• Data gathered on environmental exposures, allergens, and physiological measures.

Conclusions:

• The NCICAS Phase I study established a comprehensive dataset for understanding asthma drivers in urban pediatric populations.
• This foundational research provides critical insights for developing targeted asthma management strategies.
• The study highlights the multifactorial nature of childhood asthma in inner-city environments.
