PIP: The authors studied Brazilian maternal mortality by examining official statistics from the country's various geographical regions, including the state of Sao Paulo, Brazil. 1980 was selected because of the possibility of working with data from the Population Census of that year. The principal causes of death in Brazil were hypertension, hemorrhage, puerperal infection, and abortion. In Sao Paulo, where the 4th digit of the IDC is used, the main cause of death was eclampsia. The 2nd was hemorrhage, and the 3rd was infection, whether due to or associated with pregnancy. As for age, the lowest maternal mortality rate occurred in the 20-29 year old age group, the rate was slightly higher for those ages 15-19, and increasing gradually in those ages 30-39 and 40-49. It was not possible to analyze the rates for those ages 10-14 and over age 50 because of lack of data on livebirths. However, there were 18 deaths and 4 deaths respectively in those groups which shows that at opposite poles of the reproductive span, there exists a considerably high mortality rate. In comparing these data with those of other countries, it was found that the majority of deaths are avoidable and that it should be possible to reduce the number considerably by means of better health care for women and by using techniques and resources which are already available.
