This study used data from the 1998 Chinese Longitudinal Healthy Longevity Survey (CLHLS) and the 1998 Medicare Current Beneficiary Survey (MCBS) to compare impairment and disability in the Chinese and American Oldest-Old Populations. The standard measures of activities of daily living (ADL) were utilized for assessing functional impairment in the study subjects. Descriptive and multivariate regression analyses were undertaken to examine differences in functional impairments between Chinese and US oldest-old populations. It was found that the oldest old Chinese were less likely to have difficulties in bathing (OR= 0.748), dressing (OR= 0.555), toileting (OR = 0.838), and transferring (OR= 0.319) compared to the oldest old Americans (p < 0.01), after adjusting for age, gender and self-perceived health status. The oldest-old Chinese were more likely to have difficulty in feeding (OR= 1.12) than their counterparts but this finding was not statistically significant (p > 0.05).
