Impact of Expired Carbon Monoxide Measurement on Smoking Cessation of Pregnant Women
A study testing BabyCO and Biological samples in people with Smoking Cessation, run by University Hospital, Limoges at 1 site in France.
Trial summary
France is the country of Europe where the prevalence of pregnant women smokers is the highest (35.9% before pregnancy and in the 3rd quarter 21.8% in 2008). In the investigator's country, among the smokers of early pregnancy with the usual care, only 30% manage to stop during pregnancy. Read more about this study

About this study
Official title: Impact of Expired Carbon Monoxide Measurement on Smoking Cessation of Pregnant Women - Tobacco Pregnancy Addictive Pregnant Women
France is the country of Europe where the prevalence of pregnant women smokers is the highest (35.9% before pregnancy and in the 3rd quarter 21.8% in 2008).
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
BabyCODiagnostic test
An expired CO measurement will be performed by BabyCO and the result will be returned to the smoking pregnant woman by the consultant.
Biological samplesOther
The nature of the samples taken during the delivery are:
- maternal blood,
- cord blood
- placenta fragment
| Study group | Role | What they receive |
|---|---|---|
| Smoking pregnant woman withCO measurement | Experimental | Not described Receives: Diagnostic Test: BabyCO; Other: Biological samples |

| Non Smoking pregnant woman | Other | Not described Receives: Other: Biological samples |
What is being measured
The primary outcome is the main question the study is designed to answer.
Smoking cessation on the date of birth
Evaluate the impact on maternal smoking cessation rate at birth of a strategy combining maternal expired CO measurement, restitution, and outcome comment initiated no later than at the 24th week of amenorrhea and conducted thoughout the whole pregnancy.
Measured: Date of birth
Secondary outcomes (5)

In the investigator's country, among the smokers of early pregnancy with the usual care, only 30% manage to stop during pregnancy.
