Abstract

The purpose of this study was to analyze the effect of social frailty on physical and psychological frailty among Korean older adults, using longitudinal data with a 10-year of follow period. The survey of the Korean Longitudinal Study of Aging (KLoSA) in 2006 and 2016 were used. Among people aged 65 or older in 2006, 1,836 people (excluding those who had been diagnosed with stroke or whose cognitive ability was low) were analyzed. Social frailty was measured with four dimensions: social activity, social network, loneliness, and living alone. Physical frailty was measured using three items: sudden loss of body weight, a mean handgrip force, and exhaustion. Psychological frailty was measured in terms of cognitive function and depression. Logistic regression analysis were conducted to analyze whether the likelihood of symptoms in 2016 showed statistically significant associations with the presence or absence of social frailty in 2006 among older adults who did not already suffer from the corresponding symptoms. Lower social activities were associated with a higher risk of suffering from decline of cognitive function 10 years later, lower social networks were associated with a higher likelihood of suffering from exhaustion and depression 10 years later, and higher loneliness were linked to a higher likelihood of suffering from depression 10 years later. It is recommended to utilize social frailty in predicting and designing programs for reducing physical and psychological frailty.
