Mixture analysis identifies ozone as driving factor for child asthma symptoms.

ABSTRACT:

Background

The natural distributions of ambient air pollutants are often correlated. Existing studies have found that exposures to various air pollutants are associated with elevated risks of asthma symptoms among children. However, most studies applied single-pollutant models, which cannot distinguish between causal effects and associations due to correlations with other measured or unmeasured pollutants.

Objective

We sought to investigate air pollutant mixtures and child asthma symptoms and identify key risk factors.

Methods

The Children's Health and Air Pollution Study recruited 299 children in Fresno, California, 63 of whom had ever-diagnosed asthma. We assessed the children's prior 12-month exposures to 8 ambient air pollutants, namely, particulate matter with ae
