A review of perinatal mortality in an urban situation in a developing country.

Perinatal deaths occurring within the City of Harare, Zimbabwe, during 1983 were studied. Data were collected from all known deliveries within the city. This included exact numbers from three central maternity hospitals, and from referring midwife-run maternity clinics. An estimate was made of the number of births and perinatal deaths occurring within the city, but outside these official maternity facilities. All perinatal deaths were reviewed. The birthweight, the cause of death, and the antenatal care registration status of the mother were established. There were 2103 perinatal deaths from an estimated 53,665 total births. Deliveries include 50,138 (93.4%) in hospitals or clinics, 972 (1.8%) before arrival to the maternity service, and an estimated 2555 (4.8%) outside the city maternity services. One thousand seven hundred and fourteen (81.5%) perinatal deaths occurred in hospital or clinic delivered babies, and 134 (6.4%) from babies delivered before arrival at medical services. An estimated 255 (12.1%) of deaths occurred elsewhere. A total of 6380 (12%) patients did not register for antenatal care. There were 909 (43.2%) perinatal deaths in this unregistered group of patients. The overall perinatal mortality rate (PNMR) for infants weighing 500 g or more was 39.2/1000. For registered patients the PNMR was 25.3/1000 and for unregistered patients, 142.5/1000. For infants weighing 1000 grams or more the PNMR was 31.6/1000. The causes of death in the 2103 perinatal deaths were established and classified by clinical cause and by a simple pathological grouping with breakdown by birthweight.(ABSTRACT TRUNCATED AT 250 WORDS)
