Part of the Clinical Physiology Series book series (CLINPHY)


A number of studies have shown that, on average, blacks in the Western Hemisphere have higher blood pressure than blacks from sub-Sahara Africa (2,77,92,123). Considerable regional variations in blood pressure also exist among blacks in the Western Hemisphere (6,42,49,90). This geographical heterogeneity in the prevalence of hypertension in various black populations around the world suggests that environmental factors play a critical role in determining the prevalence of hypertension in blacks (90). The importance of environment in contributing to the prevalence of hypertension in blacks is reinforced by the observation that when rural Africans undergo changes to more urban, Western lifestyles and diets, blood pressure increases (2,23,90,93, see Chapter 7, this volume). The information in this chapter examines one important environmental factor, nutrition, and its role in contributing to high blood pressure in urbanized, Westernized blacks (Table 8.1).
