Prevelance of NIDDM among populations of the African diaspora.
Date of Publication
Uses a standardized protocol to determine the rates of NIDDM and associated risk factors in populations of the African diaspora. Representative samples were drawn from sites in Nigeria, St. Lucia, Barbados, Jamaica, the United States, and the United Kingdom. A total of 4,823 individuals aged 25-74 years were recruited. In sharp contrast to a prevalence of 2 percent in Nigeria, age-adjusted prevalences of self-reported NIDDM were 9 percent in the Caribbean and 11 percent in the U.S. and the U.K. Mean BMI ranged from 22 kg/m2 among men in West Africa to 31 kg/m2 in women in the U.S. Disease prevalence across sites was essentially collinear with obesity, pointing to site differences in the balance between energy intake and expenditure as the primary determinant of differential NIDDM risk among these populations. In ethnic groups sharing a common genetic ancestry, these comparative data demonstrate the determing influence of changes in living conditions on the population risk of NIDDM.....
