Engagement in paid work as a protective predictor of basic activities of daily living disability in Japanese urban and rural community-dwelling elderly residents: An 8-year prospective study

Aim To examine whether engaging in paid work is a predictor of maintaining good functional health among Japanese older adults in both urban and rural communities. Methods We used the 8‐year longitudinal Tokyo Metropolitan Institute of Gerontology Longitudinal Interdisciplinary Study on Aging with 30...

Description
Summary:Aim To examine whether engaging in paid work is a predictor of maintaining good functional health among Japanese older adults in both urban and rural communities. Methods We used the 8‐year longitudinal Tokyo Metropolitan Institute of Gerontology Longitudinal Interdisciplinary Study on Aging with 306 and 675 persons aged 65–84 years from Koganei City (urban) and Nangai Village (rural), respectively, who are independent in basic activities of daily living (BADL). In order to examine the declining patterns in BADL and evaluate the predictive value of working status for future BADL disability, we applied the log–rank test of cumulative proportion curves and the Cox proportional hazard model by sex, controlling for age, research fields, years of education, marital state, chronic medical conditions, pain, instrumental activities of daily living (IADL), smoking status, exercise habits, life satisfaction, usual walking speed and serum albumin for evaluating the predictive value of working status at baseline for future BADL disability. Results In both areas, participants who were not working were more likely to decline in BADL than those working (P
