Abstract
Objective: To identify the sociodemographic and gynecological-obstetric profile and the use of psychoactive substances in pregnant women treated at a high-risk outpatient clinic. Methods: Quantitative, observational and descriptive study, with a sample of 431 pregnant women. Data analysis was descriptive using the SPSS Software. Results: The prevalence of age was between 25 and 35 years old, single, complete high school and without work activity. Mostly, they were in the third trimester of pregnancy, primigravidas, without children and without prior miscarriage. The psychoactive substance most used in life was alcohol (81.0%), followed by tobacco (40.1%) and marijuana (12.8%). Tobacco was the substance with the greatest use in the last three months, being consumed daily by 53 (12.3%) pregnant women, while alcohol was consumed by 68 (15.8%) once or twice. In turn, marijuana has been used less frequently in the past three months. Conclusion: The predominance of use of legal substances (alcohol and tobacco), both in life and in the last three months and the frequency of their use, point to a challenging scenario for health professionals, thus raising the need for investing in health education strategies; addressing the damage caused to health throughout life, as well as its consequences in the pregnancy-puerperal period.
