Abstract: Objective To explore the correlation between frailty and sedentary behavior in the community elderly. Methods A total of 100 patients aged≥60 years in two communities of Jinan city were sampled by convenient sampling method, and the status of frailty and sedentary behaviors of the elderly in the community were assessed by Frailty Body Phenotype Scale, International Physical Activity Questionnaire (self-filled long questionnaire), and the correlation between frailty and sedentary behaviors of the elderly was analyzed. Results The incidence rate of frailty was 14%, and the incidence rate of pre-frailty was 41%. The average sedentary time of the elderly was 6. 59±2. 03 h/day. Compared with non-frailty group (5. 14±1. 56 h/day), the sedentary time of pre-frailty group (7. 34±1. 53 h/day) and frailty group (9. 05±0. 73 h/day) was significantly prolonged (P<0. 01). Pearson correlation analysis showed that Fried Frailty Phenotype Scale score was positive correlated with sedentary time (r=0. 706, P<0. 001). Logistic regression analysis showed that sedentary time was an independent influencing factor for frailty and 4 frailty phenotypes (low grip strength, self-fatigue, slow walking pace, low physical activity). Conclusions Sitting for a long time is an independent risk factor for frailty. Community geriatric nursing attendants could prevent the occurrence and dalay the development of frailty in the elderly by reducing sedentary behavior.
