The effects of alcohol consumption during pregnancy have been known for decades. However, alcohol consumption in pregnant women remains today a public health problem and its identification is primordial. During pregnancy, standardized self-reports such as T-ACE would help identify early women with high-risk alcohol consumption. T-ACE appears to be one of the most used during pregnancy but its diagnostic value is not objectively known.
To evaluate the diagnostic value of T-ACE self-report in the detection of high-risk alcohol consumption during pregnancy, by comparison with the dosage of a biomarker in blood.
Material and methods Multicentric diagnostic prospective study of 2425 pregnant women followed in 3 hospitals of North of France. The self-report will be offered to all women during their prenatal consultation in these 3 maternity clinics. When they returned their self-report to the medical practitioner, a unique blood test of phosphatidylethanol will be proposed to them for a period of one year. Made after informed consent, this dosage will be used as a gold standard of an alcohol consumption during the previous three weeks to establish the diagnostic value of T-ACE. An alcohol consumption will be considered " at high risk " if blood phosphatidylethanol is ≥ 20 µg/L.
With a predictable 25% rejection rate and a positive 4% T-ACE frequency, the inclusion of 2425 patients should permit to estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of T-ACE with a satisfactory 95% confidence interval in this population.
The evidence of a link between positive T-ACE and real high-risk alcohol consumption in pregnant women would objectively validate the use of this self-report during pregnancy.
The T-ACE within the self-report (self-administered questionnaire) set up in these 3 maternity hospitals in the North of France is already a reference thanks to its several advantages to better identify psychosocial risk situations and especially high-risk alcohol consumption during pregnancy than medical history. If T-ACE appeared to be a sensitive and specific method for identifying high-risk alcohol use during pregnancy, it could be generalized in the follow-up of pregnant women in our country.

A self-report, including the T-ACE, is the usual prenatal consultation procedure in the three maternities of the study. The specific procedure for the study is to perform a blood test for dosage of phosphatidylethanol in eligible pregnant women after informed consent. |
