In order to identify the maternal determinants of the consumption of medication during pregnancy according to risk class, we conducted a population cohort baseline cross-sectional study with 2,262 mothers of liveborn infants in Passo Fundo, Rio Grande do Sul, Brazil. Data were collected from the Information System on Live Births and through home interviews (an instrument adapted from the Maternity Advice Survey). The drugs were classified according to criteria. We conducted bivariate analyses and logistic regression according to the hierarchical model of determination. 80% of the mothers consumed at least one medicine during the pregnancy, distributed in risk classes as follows: A (53.4%), B (18.1%), C (24.46%), D (1.47%), X (0.06%), and V (various) (2.1%). Incomplete prenatal care and maternal age < 20 years determined the consumption of medication in class A and pregnancy complications in classes B, C, and D. In class C, cesarean section and previous abortion also determined consumption, which in class V was independent of the variables analyzed. Maternal factors, especially health complications, determine the consumption of medicines during pregnancy, suggesting that the prescribing physician should orient the safe and proper use of such medication. |
