Background Information regarding the prevalence of dizziness and its association with functional disability among African American and white residents from defined community populations is limited. Methods. A total of 6,158 persons 65 years and older (78.8% of age-eligible persons) completed in-home interviews that included three common measures of self-reported disability: the Katz Activities Of Daily Living (ADL) Scale, the Rosow-Breslau Functional Health Scale, and the Nagi Physical Disability Scale. A stratified random sample of 729 persons underwent a detailed evaluation that included questions on the frequency and severity of dizziness, which was defined as having an episode of dizziness or lightheadedness at least once a month. Results. The overall prevalence of dizziness in this population was 9.6% (95% confidence interval [CI] 7.7-12.0). It increased with age. from 6.6% in those 65-74 years old, to 11.6% in those 75-84 years old, and to 18.4% in those persons greater than or equal to 85 years old. It was more common in women (odds ratio [OR] 2.03, 95% CI 0.99-4.19) but was not associated with race. After adjusting for age, sex, and race, dizziness was associated with greater disability on the Rosow-Breslau (OR 2.29, 95% CI 1.18-4.46) and Nagi (OR 2.54, 95% CI 1.48-4.36) measures but not on the Katz ADL Stale (OR 1.18, 95% CI 0.64-2.20).
