Title Delivery outcome among women employed in the plastics industry in Sweden and Norway
Bibliographic information 1987, Vol.12, No.5, p.507-517. 22 ref.
Abstract Employment records for 1973-1981 were obtained from companies producing and/or processing plastics and these were matched with the national medical birth and malformation registers. Within the cohorts of pregnancies during which the mother held employment in a plastics factory (1,397 in the Swedish and 288 in the Norwegian study), cases of stillbirths or infant deaths, selected minformations, or low birthweight (< 2,000g) were identified. For each case, two controls from the same source were individually matched with regard to date of birth, age of mother, and parity. An increased odds ratio was found for processing of polyvinyl-chloride plastics. However, processing of cold plastics yielded a higher odds ratio than processing of heated plastics. No increased odds ratio was found for processing of styrene or polyurethane plastics. Since the whole of the plastics industry in the two countries did not participate in the studies and the number of cases was small, the result must be interpreted with caution.
