MULTIPLE BIRTHS IN HAUSA WOMEN

Abstract
The incidence of multiple births was studied using the maternity records of 5750 Hausa women living in the savannah zone of Nigeria. There were 40 twins and 2 triplets/1000 births. Some 26% of twins were monozygous. The multiple birth incidence, which was about 5 times higher than that observed in any western population, was significantly lower than that of other ethnic groups, who live in the hot and humid climate of the southern part of country. The multiple births incidence was related to maternal age but did not bear any association to the climate or malaria prevalence.
