Changing Patterns of Medical Disease in Soweto, South Africa 1981–1990

There is evidence that disease patterns in Africa may be changing. Non-communicable diseases are evolving as important health problems for example, diabetes' and ischaemic heart diseases. Urbanization seems to be a particular risk for such conditions1,3. However, little definite information is available on changes in medical disease patterns with time. We have therefore examined medical admissions to Baragwanath Hospital (which serves Soweto in South Africa) in 1981 and 1990. The studies were performed during 6 months in 1981 and 5 months in 1990 (exactly 9 years apart), and a single medical unit was used in each case. Discharge, rather than admission diagnoses were recorded in each case.
