Abstract
OBJECTIVE: The purpose of this study was to study the effect of pregnancy outcomes on risks of continued smoking in subsequent pregnancy.
STUDY DESIGN: Cohort study of first and second single births among 98,778 Swedish women who were daily smokers in first pregnancy.
RESULTS: In all, 70.2% of women continued to smoke in second pregnancy. Compared with women with a previous normal pregnancy outcome, risk of smoking in second pregnancy was increased among women with a previous small-for-gestational-age birth (adjusted odds ratio [OR], 95% CI 1.28 [95% CI 1.19-1.37]), and reduced among women who had experienced a stillbirth (OR 0.76 [95% CI 0.63-0.93]) or an infant death because of congenital malformations (OR 0.67 [95% CI 0.49-0.92]. A previous preterm birth, Sudden Infant Death Syndrome, and other causes of infant death did not influence risk.
CONCLUSION: A previous adverse pregnancy outcome has only a modest influence on smoking habits in the successive pregnancy.
