Abstract

The purpose of this study was to determine the effects of fall experience, fear of fall, and activity limitations due to fear of fall on frailty in older people. This study used national data from the 8th Korean Longitudinal Study of Aging, and frailty index was assessed by 7 divisions and 41 items: self-health assessment, physical condition, mental condition, cognitive ability, activities of daily living, instrumental activities of daily living, and chronic diseases. Stepwise regression analysis was used to identify factors influencing the participants' frailty. The average age of the participants was 76.0 ± 7.4 years. When other factors were adjusted in the final model, age(β= 0.52, p<.001), education level(β= -2.29, p<.001), presence of spouse(β= -0.75, p<.001), social network(β= -1.04, p<.001) was an influential factor in frailty. Compared to individuals without a history of falls, those with a history of falls had a higher frailty(β= 1.47, p< .001). Additionally, individuals with a little fear of fall(β= 2.87, p< .001) or a high level of fear of fall(β= 8.85, p< .001) had higher frailty compared to those with no fear of fall. Furthermore, older people with activity limitation due to fear of fall had higher frailty index scores compared to those without activity limitation(β= 5.14, p< .001). Based on the results of this study, it will be possible to prevent and improve frailty through interventions to prevent falling accidents, reduce fear of fall, and relieve activity limitation due to fear of fall.
