Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In the investigator's country, among the smokers of early pregnancy with the usual care, only 30% manage to stop during pregnancy.
Maternal smoking during pregnancy is a clearly identified risk factor for the course of pregnancy and the unborn child.
The measurement of carbon monoxide (CO) expired in pregnancy monitoring consultation is part of the recommendations of the consensus conference "Pregnancy and Tobacco" (ANAES, October 2004) and the parliamentary report on smoking by JL Touraine and D. Jacquat (Feb 2012). However, this recommendation has not entered the current practice. The research aims to justify the clinical relevance of this recommendation by demonstrating the positive impact of expired CO measurement on the rate of discontinuation during pregnancy.
