[Differences in prenatal care between health services under the Family Health Strategy and traditional primary care clinics in Rio Grande, Rio Grande do Sul State, Brazil].

This study aimed to evaluate differences in prenatal care between services under the Family Health Strategy (FHS) and traditional public primary care clinics in Rio Grande, Rio Grande do Sul State, Brazil. A cross-sectional study was performed with all women who gave birth from January 1st to December 31st, 2007, and who received prenatal care in the municipal health system. The procedures recommended by the Ministry of Health were compared according to model of care. Among the 961 pregnant women, those treated under the FHS received a higher percentage of some forms of care (use of ferrous sulfate, tetanus vaccination, and HIV and syphilis tests). Other procedures were also more frequent under the FHS, but failed to reach the recommended levels (breast examination and Pap smear). Measurement of blood pressure, uterine height, and weight were quite frequent in both groups. Identification of pregnant women in the first trimester failed to reach 70%. Women under the FHS received better care, but some procedures still fell short of expected levels, and efforts are thus needed to improve the quality of prenatal care.
