Mitigating Social Isolation Among Peritoneal Dialysis Patients: The Impact of Educational Level, Physical Activity, and Familial Support.

Objective: This study investigates the prevalence and determinants of social isolation in peritoneal dialysis (PD) patients, focusing on the influence of environmental systems and individual behaviors on their social well-being. Methods: We conducted a cross-sectional study from December 2023 to February 2024 at Shenzhen Traditional Chinese Medicine Hospital. A total of 259 PD patients were enrolled using a consecutive sampling method. Data were collected via validated tools including the Pittsburgh Sleep Quality Index (PSQI), Lubben Social Network Scale-6 (LSNS-6), Family APGAR Questionnaire, and Social Anxiety Subscale of Self-Consciousness Scale (SASS-CS). Statistical analyses utilized Spearman correlation and multiple linear regression to identify factors associated with social isolation. Results: The average score for social isolation was 11 (range 7-15). Significant predictors of social isolation included education level, physical inactivity, and normal hemoglobin concentrations. Social isolation was negatively correlated with family functionality and positively correlated with social anxiety. Regression analysis confirmed education, family functionality, and social anxiety as significant independent predictors of social isolation. Conclusion: Social isolation is common among PD patients, driven by factors such as education level, physical inactivity, and unexpectedly, normal hemoglobin levels linked to greater family isolation. Targeted interventions like education, physical activity promotion, and innovative therapies such as animal-assisted activities and social gardening can help reduce isolation and improve patient well-being.
