Title Tobacco smoke exposure and pregnancy outcome among working women - A prospective study at prenatal care centers in Írebro County, Sweden
Bibliographic information 15 Feb. 1991, Vol.133, No.4, p.338-347. 24 ref.
Abstract Among 4,687 women undergoing prenatal care in Sweden from 1980 to 1983, 678 non-smokers reported passive exposure to tobacco smoke. Of these women, 267 had been passively exposed at work, and the risk ratio (RR) for intra-uterine death (spontaneous abortion or stillbirth) among these pregnancies was increased to 1.53 compared with pregnancies of unexposed working women. The effect was confined to first-trimester foetal loss (adjusted RR=2.16), while active smoking was associated with intra-uterine death after the first trimester. Passive smoking in the workplace was weakly associated with preterm birth but not with low birth weight among full-term livebirths. Active smoking clearly increased the risk of both outcomes. However, passive exposure in the home only did not seem to affect pregnancy outcome. The lack of quantitative exposure data points to the need for more research before passive exposure to tobacco smoke can be regarded as an established hazard to foetal development and survival.
