Nitrogen dioxide exposure in school classrooms of inner-city children with asthma.

ABSTRACT:

Background

Ambient and home exposure to nitrogen dioxide (NO₂) causes asthma symptoms and decreased lung function in children with asthma. Little is known about the health effects of school classroom pollution exposure.

Objective

We aimed to determine the effect of indoor classroom NO₂ on lung function and symptoms in inner-city school children with asthma.

Methods

Children enrolled in the School Inner-City Asthma Study were followed for 1 academic year. Subjects performed spirometry and had fraction of exhaled nitric oxide values measured twice during the school year at school. Classroom NO₂ was collected by means of passive sampling for 1-week periods twice per year, coinciding with lung function testing. Generalized estimating equat
