Abstract:
Objective This study aims to explore the influence of social support on depressive symptoms and its threshold effect in elderly patients undergoing maintenance hemodialysis(MHD),thereby providing a basis for improving patients' depressive conditions.Methods A convenience sample of 440 elderly MHD patients was recruited from the hemodialysis centers of 3 general hospitals in Kunshan between October 2024 and February 2025.Data collection involved the use of a general information questionnaire,the Social Support Rating Scale(SSRS),and the Short Form Geriatric Depression Scale(GDS-15).Logistic regression and threshold effect analyses were conducted to identify influencing factors and assess their impact.Results A total of 432 valid questionnaires were recovered,yielding a response rate of 98.18％.The prevalence of depressive symptoms among elderly MHD patients was 27.8％,with an average social support score of 32.53±5.58,indicating a moderate level of social support.Logistic regression analysis revealed that the use of assistive devices,dialysis modality,marital status,social support,and type of vascular access were significant factors influencing depressive symptoms(P＜0.05).Restricted cubic spline analysis indicated a non-linear relationship between social support and depressive symptoms(P＜0.001).Threshold effect analysis showed that when the social support score was≥ 23,depressive symptoms decreased as the social support score increased(P＜0.05).Conclusion The impact of social support on depressive symptoms in elderly MHD patients has a critical threshold.This finding suggests that clinical healthcare providers should prioritize interventions for patients with low social support to improve their physical and mental health and quality of life by enhancing social support levels.
