Objective:

The primary study objectives are to: (1) evaluate the association between personal air concentrations of total carbonyls and variability of lung function (peak expiratory flow rate and forced expired volume in the first second) in a sample of middle school children with labile, persistent asthma; and (2) evaluate the association between personal air concentrations of total carbonyls and the variability of selected clinical indicators (asthma symptoms and medication use) in a sample of middle school children with labile, persistent asthma.

Approach:

A repeat measurement study design will measure exposure to carbonyl-containing toxic air pollutants over a 12 month period. The study population will center on labile, persistent asthmatics because they are likely to manifest greater variability in health outcomes following exposure to airborne stimuli. Four 1 week measurement periods, for each of the exposure and health outcome variables, will be performed over the 12 month observation period.

Expected Results:

To the best of our knowledge, this study is the first effort to examine the relationship between measured personal exposure to carbonyl-containing toxic air pollutants and aggravation of asthma. Very little is known about the variability of microenvironmental levels of toxic air pollutants, and the major determinants of concentrations and exposures. We expect the results of this study to contribute to a better understanding of important environmental triggers of asthma in children.
