ABSTRACT
The article describes the temporal evolution of prenatal quality indicators in the primary health care network in Brazil and investigates regional differences. This study used data from the external evaluation of Brazil's National Program for Improving Primary Care Access and Quality (PMAQ) with health teams participating in Cycles I, II and III of the Program, carried out respectively in 2012, 2013/14 and 2017/18. The number of visits, physical examination procedures, guidelines and request for laboratory tests were investigated. There was a positive evolution for tests-HIV, syphilis, blood glucose and ultrasound, and for all tests, guidance on feeding and weight gain of the baby and examination of the oral cavity. The indicators that performed the worst were: performance of tetanus vaccine, six or more visits, receiving guidance on exclusive breastfeeding and care for the newborn, and the procedures-all, measurement of uterine height, gynecological exam and cervix cancer prevention. These changes had a varied behavior between the regions of the country.
