Concept
Smoking and pregnancy
Summary
Tobacco smoking during pregnancy causes many detrimental effects on health and reproduction, in addition to the general health effects of tobacco. A number of studies have shown that tobacco use is a significant factor in miscarriages among pregnant smokers, and that it contributes to a number of other threats to the health of the foetus.
Because of the associated risks, people are advised not to smoke before, during or after pregnancy. If this is not possible, however, reducing the daily number of cigarettes smoked can minimize the risks for both the mother and child. This is especially true for people in developing countries, where breastfeeding is essential for the child's overall nutritional status.
Women who are pregnant or planning to become pregnant are advised to stop smoking. It is important to examine these effects because smoking before, during and after pregnancy is not an unusual behavior among the general population and can have detrimental health impacts, especially among both mother and child, as a result. In 2011, approximately 10% of pregnant women in data collected from 24 U.S. states reported smoking during the last three months of their pregnancy.
According to a 1999 meta-analysis published in The American Journal of Preventative Medicine, smoking prior to pregnancy is strongly related to an increased risk of developing an ectopic pregnancy.
According to a study conducted in 2008 by the Pregnancy Risk Assessment Monitoring System (PRAMS) that interviewed people in 26 states in the United States, approximately 13% of women reported smoking during the last three months of pregnancy. Of women who smoked during the last three months of pregnancy, 52% reported smoking five or fewer cigarettes per day, 27% reported smoking six to 10 cigarettes per day, and 21% reported smoking 11 or more cigarettes per day.
In the United States, women whose pregnancies were unintended are 30% more likely to smoke during pregnancy than those whose pregnancies were intended.
