Study Summary
We propose to conduct a study to increase our understanding of farming practices and of the potential for previous exposure to DDT in North Carolina African American male agricultural workers, a group especially likely to have had high DDT exposure. Because of potentially widespread DDT exposure from agricultural activities, African American farmers and farm workers may be uniquely at risk for any associated health effects. However, little is known about levels of pesticide exposure in African American farming populations. Three hundred and eighty-nine African American men who are current or former farmers or farm workers will be asked to participate in the study. These men are members of the Supplemental Minority Cohort of the NCI/NIEHS/EPA Agricultural Health Study (AHS). The AHS is a prospective study of the potential health effects associated with agricultural exposures. Men in the supplemental cohort were recruited in 1996. At that time, they completed an enrollment questionnaire that focused on lifetime agricultural exposures, demographics, lifestyle factors and health. In this new study, a follow-up questionnaire will be administered by telephone by a trained interviewer to all men. Following the interview, the participant will be asked to donate a blood specimen, to have anthropometric indices (e.g., height, weight, waist and hip circumference, etc.) measured, and to have a top- and side view Polaroid photograph of their head taken during one visit to a central community location, such as the local church or health clinic. We will quantitatively document serum p,p'-DDE levels, correlate these with self-reported farming activities and DDT exposure, and describe the health status of these men. We will also correlate serum p,p'-DDE levels and androgen concentrations, since p,p'-DDE is thought to be a potent androgen receptor antagonist. This exploration of the potential link between levels is important because the demonstration of any subclinical physiological
