Research Category: Human Health
Objective:
Exposure to toxic compounds can be influenced by microenvironmental influences and by human activity patterns that bring persons in contact with exposures. A major gap in the current knowledge base is related to variability across time, as most attempts to generate exposure data have been cross-sectional or short-term. There are also key methodologic issues in recruiting representative participant groups from the population for the collection of data at multiple time points.
Approach:
The proposed project will develop data collection platforms that can be used in longitudinal assessments of change in exposure-related behaviors. These platforms, which are designed to vary in the demand on participants, will then be tested in a population-based sample of households. The data to be collected will characterize short-term, seasonal, and long-term changes in daily activities, food consumption habits, and use of household and personal care products. Since human activity patterns can change rather quickly, we will conduct longitudinal multiple tiered assessment of exposure-related behaviors. We will evaluate multiple data collection methods for validity (accuracy), precision, cost, and user acceptability. Three data collection methods will be used: validated behavioral surveys administered by telephone; web-administered versions of these same surveys; and passive measures of behavior.
Expected Results:
The study results will be used to 1) make recommendations for a national, longitudinal data collection platform to assess exposure-related behaviors, and 2) create datasets for the EPA for public use in a format compatible with the Consolidated Human Activity Database (CHAD).
