Design considerations in pregnancy outcome studies of occupational populations.
Scand J Work, Environ & Health 1981 Dec; 7(Suppl 4):76-82
Epidemiologic studies of the relationship between occupational exposure and pregnancy outcomes are described. Traditional versus occupational studies are discussed in relation to study design considerations. Included in the discussion are factors affecting study population size, population size and outcome under study, population sizes for occupational studies exposures under study, and comparison populations selection. The data sources for both traditional and occupation pregnancy outcome studies are also reviewed, such as recorded data sources including fetal death certificates, and interview data. Problems of identifying data sources and the accessibility of the research population to the researcher are examined.
