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. Twenty six per cent of twins were monozygous. The incidence of multiple births, which was about five 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 pat of country. The incidence of multiple births was related to maternal age but did not bear any association to the climate or prevalence of malaria.
