A Meta-Analysis of the Variables Related with Activities of Daily Living among Older Adults: focused on Socioeconmic Status and Psychosocial factor from Perspectives on Health Equity

Abstract

The purpose of this study was to carry out from a health equity perspective a meta-analysis of the effects of socioeconomic status and psychosocial factors on activities of daily living among older adults. We employed meta-regression analysis to examine whether those effects have been affected by certain moderators. We analysed a total of 377 effect sizes computed from 56 studies published in Korea before 2014. Our meta-analysis revealed that psychosocial factors have more effects than socioeconomic status on activities of daily living among the elderly. In the socioeconomic status variables, “occupation” showed the largest effect size, while among the psychological variables, “social activities” had the largest effect size. Meta-regression reported that the effect of “functional support” on the elderly was larger for women and rural dwellers. The effect of “earned income” was larger for those living in small-and medium-sized cities than for the rest. The more recent the survey, the larger the effect size of non-family’ support. The findings suggest the following. Firstly, social support should be provided first in the elderly. Secondly, infrastructures need to be expanded to better support the elderly in their work and social activities. Third, each of social policy supports should be enforced according to gender, residential area and survey date.
