[Pregnancy and substance use in France: a literature review]. / Grossesse et usage de substances psychoactives en France. Synthèse de la littérature.

ABSTRACT

OBJECTIVES: Substance use during pregnancy is an important public health issue. It requires identifying at-risk populations and risk perception among women. MATERIALS AND METHODS: A literature review was conducted. It included French studies conducted since 2000 on substance use during pregnancy (tobacco, alcohol, marijuana, psychotropic drugs) and risk perception. RESULTS: In France, in 2010, 24% of pregnant women smoke--17% in the 3rd trimester. Depending on studies, the prevalence of alcohol use ranged from 12 to 63% and binge drinking ranged from 1 to 7%; daily drinking was below 0.5%. Marijuana use ranged from 1 to 3%, and psychotropic drugs ranged from 2 to 4%. Little research has been dedicated to risk perception. Studies show a lack of awareness about the equivalence of risks between fermented and distilled beverages and about the risks of moderate smoking during pregnancy. CONCLUSION: Data is lacking to characterize at-risk populations and mechanisms underlying risky behaviors.
