We compared the initiation of prenatal care during the first trimester of pregnancy (adequacy of initiation) between mother’s recall and the prenatal health information system (SISPRENATAL). We asked 238 women that received prenatal care at Family Health Units in Vespasiano, Minas Gerais their gestational age at first prenatal visit. Both recall and SISPRENATAL indicated that 30% of women had inadequate initiation. There was fair agreement in the adequacy of initiation (Kappa=0.35, 95% CI: 0.22-0.48) between recall and SISPRENATAL. Through regression models, we found that agreement was more likely with mother’s shorter recall period and non-use of the private sector. Use of the private sector (16.4%) was also correlated with a later date of initiation by SISPRENATAL than by mother’s recall. In sum, differences in the adequacy of initiation between recall and SISPRENATAL were associated with longer recall periods and with use of the private sector. Despite the limitation of recall bias, mother’s recall is preferable to SISPRENATAL for capturing the public use by the pregnant women.
