ADL DEPENDENCE AND MEDICAL CONDITIONS IN CHINESE OLDER PERSONS - A POPULATION-BASED SURVEY IN SHANGHAI, CHINA

OBJECTIVE: To describe the prevalence of activities of daily living (ADL) dependence and medical conditions and the relationship between illnesses and ADL performance in the older population of Shanghai, China. DESIGN: Probability sample survey of community residents. SETTING: The Jing An district of Shanghai, China. The interviews were carried out at the homes of the older persons. PARTICIPANTS: There were 3763 noninstitutionalized elders screened, 3745 of whom completed the interview. MEASUREMENTS: The dependent variables were the five basic ADL items: eating, dressing, transferring, toileting, and bathing. The independent variables were dementia and 19 self-reported medical conditions, along with age, gender and education level. MAIN RESULTS: Of those in Shanghai aged 65 and older, 8.28\% (6.52\% of males, 9.17\% of females) were functionally dependent in one or more ADLs. The most prevalent self-reported illness was cardiovascular disease, including hypertension (29.12\%) and heart disease (26.65\%). ADL performance was associated with dementia and a number of medical conditions in univariate analysis. The best predictors of functional dependence in both age groups (65-74 years; 75 years and older), based on the multiple logistic regression analysis and after controlling for age, gender, and education, were stroke, dementia, Parkinson's disease, diabetes, and emphysema CONCLUSIONS: The authors have successfully applied five ADL items selected and culturally adapted from Older Americans Resources and Services to the study of older Chinese. A consistent and reliable estimate of functional dependence among older persons is obtained. The prevalence of dementia and many self-reported illness, as well as the ADL status by medical condition, are reported. The findings reveal certain patterns of relationship between illness conditions and ADL performance
