Incidence and Course of Activities of Daily Living Disability Over 6 Years in Community-Dwelling Older Adults: Examination Stratified by Frailty, Age, and Gender
摘要
We investigated characteristics and differences in activities of daily living (ADL) disability incidence according to gender, age, and frailty status in 4,985 community-dwelling older adults aged ≥ 65 years living in Japan. ADL disability is care level ≥ 2 in long-term care insurance. The cumulative care incidence over 6 years was compared. In the 6-year period, 654 older adults exhibited ADL disability. Age effect was most strongly related to ADL disability occurrence, followed by frailty status. Gender differences were observed in the 75–84-year-old pre-frail and robust groups. ADL disability incidence was higher in men, with a higher prevalence of low cognitive function and depression risk; at 75–84 years of age, men became ADL disabled, which was earlier than women. Therefore, gender differences must be considered for older adults in the 75–84-year age group when examining risk of long-term care and frailty as an outcome.
