Perinatal death due to abruptio placentae in an African city.

Abruptio placentae was a common cause of perinatal death in Addis Ababa, Ethiopia in 1974-1975 with a frequency of 5.5/1000 births. This disorder had its peak frequency at term. No abnormalities were found in the placentas to explain the placental abruptions but there were other clues to their genesis. There was a strong association of the fatal abruptions with severe poverty in the mothers. These poor mothers were both undernourished and malnourished during pregnancy. Their fetuses and neonates who died had multiple evidences of undernutrition including a relative undergrowth of adrenals, spleens and livers and a relative acceleration of lung maturation. These findings support observations in more prosperous nations that poor nutrition of the gravida may have an important role in the genesis of abruptio placentae.
