Description:

Objective:

The Community-Based Prevention Research (CBPR) component of the Center is the CHAMACOS birth cohort study of the potential health effects of pesticide and allergen exposures to pregnant women and their children. The specific aims of the project are to determine whether organophosphate pesticide exposure in utero and/or during the postnatal period is associated at preschool and school-age with: 1) poorer neurodevelopment and behavioral performance; 2) slower somatic growth; 3) atopy, active asthma or asthma-like symptoms, and airway reactivity; and, 4) autonomic nervous system dysfunction. We are also investigating the relationship between environmental antigens and respiratory outcomes in our populations.

Approach:

OP exposure will be defined by levels of six non-specific OP metabolites measured in urine collected from mothers at enrollment, 26-weeks gestation, and postpartum, and from children at 6-, 12-, 24-, 42-, and 60-months of age. Exposures related to respiratory outcomes will be assessed by home inspection, questionnaire, and, for a subset of children, measurements of allergens and endotoxin in children’s homes. We will assess growth and perform a battery of neuropsychological assessments (e.g., cognition, memory, attention, motor) of the children at 42- and 60-months, and obtain teacher and parent evaluation of behavior and school performance at 84-months. We will assess respiratory health by questionnaire, medical record review, blood analysis of IgE and Th1 and Th2 cytokines, and tests of lung function and airway reactivity at 60-months.

Expected Results:

This research will enhance our knowledge of the health and development of these hard-to-reach low-income Latino children living in agricultural areas and provide critical information on the health effects of organophosphate pesticide exposure to children for the U.S. Environmental Protection Agency’s implementation of the Food Quality Protection Act.
