ABSTRACT
In South Africa there are four ethnic populations: blacks (25 million), coloreds (Euro-AfricaMalay) (3 million), Indians (1 million), and whites (5 million). These populations exhibit considerable differences in patterns of diseases. Indeed, between them they afford probably greater contrasts, as juxtaposed populations, than are encountered elsewhere in the world. The Asian population exhibits high frequencies of obesity, hypertension, diabetes, and coronary heart disease (CHD).
