Occupational Hazards to Pregnant Women in the Collaborative Perinatal Project.
NIOSH 1980 Oct:377-404
The Collaborative Perinatal Project is described. Objectives of the prospective longitudinal study involving 58,760 women and their offspring are discussed. Considerations involved in selection of the participants and data collection are reviewed. Data on the demographics of the population and on the women who were lost to the study is included. Methods used to determine and quantify occupational chemical exposures are provided. Chemical exposure was associated with uterine bleeding during the second trimester in women of lower socioeconomic status. Pesticide exposure had the most adverse effect on pregnancy outcome. Heavy lifting and exposure to heat also had negative effects. The authors recommend reexaminations of the data based on duration of exposure, single and multiple exposures, and birth order of the offspring.
