Abstract
France is the country in Europe where the prevalence of pregnant women who smoke is highest (35.9% before pregnancy and 21.8% in the third trimester, in 2008). According to the national perinatal survey of 2016, 17.1% still smoke in the third trimester. Currently, the screening and management of smoking in pregnant women is done on the basis of the daily cigarette number and minimum advice is provided. Improving the efficiency of prenatal care regarding maternal smoking is essential. No systematized practice, including the measurement of carbon monoxide (CO) in exhaled air, has generally been implemented in pregnancy followup.
A 36-month, comparative, randomized, interventional study is being conducted in two parallel arms (experimental vs. normal management) of 300 patients each. The main objective is to assess the impact of the measurement of maternal expired CO followed by personalized information versus standard care on the rate of effective cessation of maternal smoking at childbirth. Secondary objectives are to evaluate its impact on maternal-fetal pathologies and on the intention of breastfeeding. Smoking cessation is based on patient self-report expired CO <3 ppm.
The results indicated that our hypothesis is the expired CO measurement strategy as part of prenatal consultations will increase by 50% the rate of smoking cessation among pregnant women.
The study aims to promote a clinical approach integrating biological (measurement of expired CO) and psycho-social dimensions against smoking during pregnancy.
The measurement of expired CO aims to reduce maternal smoking and perinatal health inequalities by increasing the efficiency of prenatal care.
