The maternal mortality rate is considered an important indicator of quality of care during the gravid-puerperal cycle. To shed light on the maternal mortality pattern in the city of Rio de Janeiro, maternal deaths from 1993 to 1996 among residents of the city were analyzed, based on data from death certificates. The maternal mortality rate was calculated according to cause, age, and schooling. High annual mortality rates were detected throughout the period analyzed (74.3, 47.9, 51.5, and 55.3 per 100,000 live births, respectively). Main causes of death were hypertension, hemorrhage, and puerperal complications. Greatest risk of death was among the youngest and oldest women and those with less schooling. The study discusses strategies to decrease under-recording of deaths and increase quality and results of care.
