This project will examine the cohort of women and their offspring who were exposed to polybrominated biphenyls (PBB) as a contaminant of cattle feed in l973. The Michigan Department of Community Health has followed this cohort for more than 20 years. The project will ascertain the occurrence of a number of outcomes in the women and their offspring in order to determine if there is evidence of endocrine disruption associated with PBB exposure.
The study will include the administration of a telephone interview to the approximately 1900 women currently in the cohort to ascertain the cumulative incidence since exposure of endocrine sensitive endpoints such as endometriosis, benign breast disease, abnormal Pap smears, uterine fibroids, thyroid dysfunction and infertility. We will ascertain time to pregnancy for each pregnancy following exposure. Medical records will be obtained and reviewed to verify each of the clinical conditions. The occurrence of each of these outcomes will be modeled by multivariate methods as a function of PBB serum level in l976 controlling for potentially confounding variables.
This cohort, by virtue of its well-characterized exposure to PBB and the long follow-up period, can provide valuable data on the potential endocrine disrupting effects of halogenated hydrocarbons.
