Short-term associations between ambient air pollutants and pediatric asthma emergency department visits.

ABSTRACT:

Rationale

Certain outdoor air pollutants cause asthma exacerbations in children. To advance understanding of these relationships, further characterization of the dose-response and pollutant lag effects are needed, as are investigations of pollutant species beyond the commonly measured criteria pollutants.

Objectives

Investigate short-term associations between ambient air pollutant concentrations and emergency department visits for pediatric asthma.

Methods

Daily counts of emergency department visits for asthma or wheeze among children aged 5 to 17 years were collected from 41 Metropolitan Atlanta hospitals during 1993-2004 (n = 91,386 visits). Ambient concentrations of gaseous pollutants and speciated particulate matter were available from stationary monitors during t
