Waist circumference, BMI and the prevalence of self-reported diabetes among the elderly of the United States and six cities of Latin America and the Caribbean.
Using data from the Salud Bienestar y Envejecimiento (SABE) project and the U.S. National Health and Nutrition Examination Survey (NHANES 1999-2004), we examined the prevalence of obesity and diagnosed diabetes among older adults in the Americas; we also examined the association of age, sex, level of education, weight status, waist circumference, smoking, and race/ethnicity with diabetes among older adults. The prevalence of diagnosed diabetes was highest in the US Blacks and Mexican Americans, followed by Bridgetown and Mexico City (22% for each) and lowest in Santiago, Montevideo, Havana, and US Whites (13-15%). Diagnosed diabetes was significantly associated with BMI among participants from Bridgetown, Sao Paulo, and the three US ethnic groups, while it was associated with waist circumference in all sites except Mexico City. Our findings suggest major geographical and ethnic variation in the prevalence of diagnosed diabetes among older adults. Waist circumference was more consistently associated with the prevalence of diagnosed diabetes than BMI. Higher prevalences of diabetes are found among the elderly of African or Mexican descent in the United States and in other countries of the Americas when compared to the prevalence among whites in the United States and in other Latin American countries with populations of predominant Western European descent.
