Predictors of physical disability in elderly blacks and whites of the Charleston Heart Study.
During the 1984/85 recall of the Charleston Heart Study Cohort, physical function data were obtained for 247 white males, 376 white females, 123 black males, 247 black females and 71 high socioeconomic status (SES) black males over 60 years of age. Black females had the highest prevalence of physical disability (55.8%), followed by white females (43.2%), black males (39.0%) and white males (25.8%) and high SES black males (22.3%). Physical disability was 1.5-2.5 times as prevalent among individuals with a history of cardiovascular disease (CVD) than those without such a history. Among individuals without a current history of CVD univariate analyses showed the following as significant (lower 95% CI greater than 1.0) predictors of physical disability: elevated systolic blood pressure in white females, black males, and black females; elevated cholesterol in black females; obesity in black females; and low educational level in white females. Regression analyses indicated that obesity in 1960 accounted for 10.9 and 2.9% respectively of the variability in physical disability scores in 1985 for black females and white females.
