Abstract

Objective

To use spatial analysis methodology to analyze residential and school proximity to major roadways and pediatric asthma morbidity.

Methods

The School Inner-City Asthma Study (n=350) recruited school-aged children with asthma. Each participant’s school and home addresses were geocoded and distances from major roadways were measured to calculate a composite measurement accounting for both home and school traffic exposure. Generalized estimated equation models were clustered by subject and adjusted for age, race/ethnicity, gender, income, environmental tobacco smoke, controller medication, upper respiratory tract infections and seasonality.
