Objective To understand the social frailty status of peritoneal dialysis patients and its influencing factors, in order to increase the attention of medical staffs to the social frailty of peritoneal dialysis patients, and provide reference for clinical prevention of social frailty and early intervention.

Methods A total of 147 patients undergoing peritoneal dialysis were selected as the research subjects.The general information, disease condition and individual behavior information of patients were collected.The investigation was conducted using the help, participation, loneliness, financial, talk scale (HALFT), distress disclosure index (DDI), Lubben social network scale-6(LSNS-6), social identification scale, and self-perceived burden scale (SPB).The influencing factors of social frailty were analyzed.

Results The social frailty score of 147 patients was (1.32±1.52) points, with 30 patients in the stage of social frailty (20.41%), 46 patients in the early stage of social frailty (31.29%), and 71 patients without social frailty (48.30%).Univariate analysis showed that there were statistically significant differences in social frailty scores among patients of different ages, economic status, educational level, place of residence, sleep, exercise, and loneliness (P < 0.05 to P < 0.01).Social frailty was negatively correlated with self-disclosure, family network, and friend network (P < 0.05 to P < 0.01), and significantly positively correlated with social exclusion and self-perceived burden (P < 0.01).Age, loneliness, self-disclosure, friend network, social exclusion, and self-perceived burden were the main influencing factors of social frailty in peritoneal dialysis patients (P < 0.05 to P < 0.01), accounting for 51.0% of the total variation.

Conclusions The proportion of peritoneal dialysis patients with social frailty and pre-social frailty stages is relatively high.In clinical nursing work, greater attention should be paid to older patients, focusing on evaluating their psychological state, to enhance patients′ self-disclosure and friend networks, reduce loneliness, social exclusion, and self-perceived burden, and provide more support and social behavior opportunities.
