Influence of maternal smoking on placental abruption in successive pregnancies: a population-based prospective cohort study in Sweden

Ananth, C. V., Cnattingius, S.·2007·American Journal of Epidemiology

Abstract

The authors examined associations between cumulative smoking during a woman's first and second pregnancies and risk of placental abruption in the second pregnancy. They performed a population-based prospective cohort study of 526,690 women who delivered their first two consecutive singletons in Sweden in 1983-2001. Using logistic regression models, the authors found that, among women without placental abruption in the first pregnancy, smoking was associated with increased risk of abruption in the second pregnancy; however, this effect was confined to exposure occurring during the second pregnancy (adjusted odds ratio (OR)=1.8, 95% confidence interval (CI): 1.4, 2.3) but not the first (adjusted OR=1.1, 95% CI: 0.9, 1.3). Among women with a prior abruption, the risk of repeating abruption was increased irrespective of smoking habits. When women smoked during both pregnancies, there was an almost 11-fold increase in risk (adjusted OR=10.9, 95% CI: 7.3, 16.3). These findings suggest that women who quit smoking before pregnancy may benefit from reduced risk of abruption. The observation that the recurrence of abruption is substantially increased regardless of changes in smoking habits suggests that factors other than smoking may influence the recurrence of placental abruption.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
