Diabetes mellitus in the urbanized Johannesburg African
Diabetes mellitu is a common and important clinical problem in the urbanized Johannesburg African. A survey of Africans aged 30 and over attending the Baragwanath Hospital Casualty Department showed an incidence of diabetes of about 1%.1 Yet, apart from Campbell's studies on the Zulu diabetic, a search of the literature yielded little of note on diabetes in the South African Bantu. We have therefore undertaken an analysis of the records of 250 new cases of diabetes mellitus in African subjects admitted to Baragwanath Hospital during the period 1951 - 1957. These cases were selected at random and constituted at least 75% of all the new African diabetics admitted during this period.
