RESUMEN
OBJECTIVE: To evaluate the knowledge of pregnant women and the clinical management of hemolytic disease of the fetus and newborn, as well as to describe the gestational profile, risk factors and socio-epidemiological profile of pregnant women treated at two municipal health units in Belém (Pará, Brazil). METHODS: This was a cross-sectional analytical study, which consisted in the application of questionnaires to pregnant women who underwent prenatal care at the municipal health units. RESULTS: A total of 104 pregnant women were evaluated; most were aged between 24 and 29 years old, had high school degrees (38 %), family incomes between 1 and 2 minimum wages (45 %) and blood type O+ (43 %). Regarding the gestational profile, the participants were predominantly in the third trimester of pregnancy (49 %), started prenatal care in the first gestational trimester (81 %) and were primiparous (61 %). Failures in the management of prenatal care were observed, especially with regard to access to information about the disease, since most pregnant women did not receive information about blood incompatibility during prenatal care. This led to limited knowledge about the pathology of the disease evidenced by the fact that most of the correct answers were between Questions 0-4, which were significantly associated with the women's education and income. CONCLUSIONS: Although hemolytic disease of the fetus and newborn is serious, the pregnant women in this study demonstrated little knowledge about the disease and had inadequate care by health professionals, reinforcing the importance of improving care for women's health and prenatal care.
