| Résumé : | [BDSP. Notice produite par INIST wiR0xFgA. Diffusion soumise à autorisation]. Objective : To determine the prevalence and 3-year incidence of dementia in Blacks and Whites age 65 and older in a five-county Piedmont area of North Carolina. Design : Stratified random sample of members of the Duke Established Populations for Epidemiologic Studies of the Elderly (EPESE) (baseline n=4,136 ; 55% Black ; weighted n 28,000). Prevalence study members were differentially selected on the basis of score on the Short Portable Mental Status Questionnaire at the second in-person Duke EPESE wave. Incidence study members included all persons with obvious cognitive decline over a 3-year period, and a 10% sample of the remainder. Measurements ; Self-and informant report on bealth history, functional status, and memory. Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Neuropsychology Battery administered to all subjects, and CERAD Clinical Battery to those with impaired memory, Clinical consensus to determine presence and type of dementia. Results : Prevalence of dementia for persons 68 years old was 0.070 (95% confidence interval=0.021-0.119) for Blacks and 0.072 (0.022-0.122) for Whites, Rates for Black men (0.078,0.001-0.155) exceeded those for Black women (0.066,0.003-0.129), but gender rates for Whites were reversed (men : 0.044,0.000-0.103), (women : 0.087,0.015-0.160). Neither race nor gender differences were significant. Prevalence of dementia increased through age 84 and tapered off thereafter. Three-year incidence of dementia was 0. (...) |
