Abstract

BACKGROUND
It is important to evaluate the functional ability of the elderly for optimal care. This study was conducted to identify factors associated with dependence for activities of daily living (ADL) and instrumental activities of daily living (IADL) in elderly adults in Korea. METHODS: A cross-sectional study of data from the third Korea National Health and Nutrition Examination Survey (KNHANES III) 2005 was undertaken. The sample consisted of 3,656 participants, 65 years of age or older. Multifactorial regression analysis was used to identify associations between ADL and IADL dependence and sociodemographics, lifestyle, and health history. RESULTS: Among the 629 (17.2%) ADL-dependent and significantly and independently associated factors were age, lower education level, health assistance or no-insurance, stroke, urinary incontinence, diabetes, arthritis, and lung cancer. Among the 1,674 (55.7%) IADL-dependent and significantly and independently associated factors were age, lower education level, single or widowed, male, stroke, arthritis, glaucoma and/or cataract. CONCLUSION: Functional dependence in older adults was directly related to aging and had multiple determinants. Awareness of these determinants should help design health programs that can identify individuals who are at high risk of losing their independence, and implement interventions for slowing or reversing the process.
