Parity and perinatal mortality amongst diabetics in a Nigerian Teaching Hospital.

The parity and the perinatal mortality of 226 married Nigerian female diabetics, aged 20 to 76 years (mean 47.1 years), and 226 married female nondiabetics matched for age and educational level with the diabetics were studied. There was no statistically significant difference between the diabetics and nondiabetics in terms of primary infertility, irrespective of age of onset of diabetes. In the group with one to four deliveries, the nondiabetics significantly outnumbered the diabetics (P less than 0.001) irrespective of age of onset of diabetes. In the group with seven to nine deliveries, only the diabetics of child-bearing age (P less than 0.01); and in the group with 10 or more deliveries, diabetics significantly outnumbered the nondiabetics irrespective of age of onset of diabetes (P less than 0.01). There was a statistically significant difference between the diabetics and nondiabetics in terms of the overall perinatal mortality (P less than 0.001). However, this difference was not significant in diabetics of childbearing age. In Nigeria, where large families are common and children often born in rapid succession, high parity appears not only to increase the chances of a woman developing diabetes in late life but also in early life. Effective birth control practice may thus help in reducing the incidence of diabetes amongst Nigerian women. Additionally, a programme extending to the rural areas aimed at early detection of diabetes and proper management of the pregnant diabetic by a team of medical personnel with special interest in diabetes will help in reducing the perinatal mortality in Nigerian diabetics.
