Objective: To evaluate the socio-cultural factors associated with alcohol consumption by women, in the previous year, and during the gestational period (not knowing that they were pregnant).

Method: This is a cross-sectional study, conducted with 112 pregnant women using Primary Health Care services in two municipalities in São Paulo state, Brazil. Sociodemographic and obstetric information tests to identify problems associated with alcohol were used.

Results: The majority of participants were young, married, were of the Evangelical faith, had a low level of education and family income, did not work and lived in their own homes. The prevalence of alcohol use in the year before pregnancy was 57.1%, 6.8% drank in a binge pattern, of which 32.1% did not know they were pregnant.

Conclusion: Pregnant women and women of reproductive age, who are in risk groups and have a high vulnerability, should take priority for interventions related to substance use, especially alcohol.
