The prevalence of hypertension in seven populations of West African origin.
American Journal of Public Health
Date of Publication
Describes the distribution of blood pressures, hypertension prevalence, and associated risk factors among seven populations of West African origin. Compares the rates of hypertension in West Africa (Nigeria and Cameroon), the Caribbean (Jamaica, St. Lucia, Barbados), and the United States (metropolitan Chicago, Illinois) on the basis of a highly standardized collaborative protocol. Sample consisted of 10014 adults over the age of 25 in seven sites. A consistent gradient of hypertension prevalence was observed, rising from 16 percent in West Africa to 26 percent in the Caribbean and 33 percent in the United States. Mean blood pressures were similar among persons aged 25 to 34, while the increase in hypertension prevalence with age was twice as steep in the United States as in Africa. Environmental factors, most notably obesity and the intake of sodium and potassium, varied consistently with disease prevalence across regions. The findings demonstrate the determining role of social conditions in the evolution of hypertension risk in these populations.....
