Air pollution and respiratory symptoms among children with asthma: vulnerability by corticosteroid use and residence area.

ABSTRACT:

Rationale

Information on how ambient air pollution affects susceptible populations is needed to ensure protective air quality standards.

Objectives

To estimate the effect of community-level ambient particulate matter (PM) and ozone (O) on respiratory symptoms among primarily African-American and Latino, lower-income asthmatic children living in Detroit, Michigan and to evaluate factors associated with heterogeneity in observed health effects.

Methods

A cohort of 298 children with asthma was studied prospectively from 1999 to 2002. For 14days each season over 11 seasons, children completed a respiratory symptom diary. Simultaneously, ambient pollutant concentrations were measured at two community-level monitoring sites. Logistic regression models using generalized esti
