Background: Tobacco use during pregnancy is detrimental to pregnant women and to the fetus. In Galicia, the data regarding prevalence of tobacco use during pregnancy is outdated and the characteristics of women who continue to smoke during pregnancy are not known. The objectives of this work were to estimate, before and during pregnancy, the prevalence of tobacco use and characterize its consumption, and to identify factors associated with the maintenance of tobacco use during pregnancy.
Methods: A cross-sectional study was conducted in 2016 targeting women who had given birth within the previous 12 months (n=6.436) in Galicia. Information was collected regarding the mother’s status before and during pregnancy, at the time of delivery and survey. Smoking prevalence was estimated both globally and by women related characteristics. Regression models were performed to identify variables associated with smoking maintenance. Prevalence and odds ratio are presented accompanied with 95% confidence interval.
Results: Smoking prevalence during pregnancy was 11.9% (11.1–12.8). Among women who maintain tobacco consumption during pregnancy, the percentage of cigarette smokers decreased, but prevalence of rolled tobacco remain stable. The maintenance of smoking during pregnancy was related to being Spanish, education or having been a daily smoker before pregnancy.
Conclusions: Despite the fact that more than half of Galician women stop smoking during pregnancy, smoking prevalence remains at 12%. The different demographic factors identified in this study as predictors of smoking maintenance, should be kept in mind when intervention programs focused on pregnant women will be design.
