【Abstract】Objective To explore the quality of life (QoL) in elderly patients with maintenance hemodialysis (MHD) and analyze its influencing factors. Methods A total of 140 elderly MHD patients admitted to the First Hospital Affiliated to Nanjing Medical University from March 2021 to June 2023 were selected as the study subjects. The 36-item short form health survey (SF-36) was used to assess QoL, the Pittsburgh sleep quality index (PSQI) was used to assess sleep status, and Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were used to assess depression and anxiety. SPSS 26.0 was used for data analysis. According to the data type, t test or one-way analysis of variance (ANOVA) was used for inter-group comparison. Spearman correlation analysis was used to analyze the relationships between the influencing factors of QoL and physical health and mental health. Multiple linear regression was used to analyze the influencing factors of QoL. Results The SF-36 score was (213.85±17.19) points for physical health and (156.24±11.73) points for mental health in the 140 elderly MHD patients. Univariate analysis showed that the physiological health scores were significantly different in age, education, marital status, working status, family per capita monthly income, hemodialysis frequency, sleep quality and anxiety (P<0.05), and that mental health scores differ significantly in family per capita monthly income, payment method of medical expenses, social support, anxiety and depression (P<0.05). Spearman correlation analysis showed that family per capita monthly income and sleep quality were positively correlated with physical health score (r=0.396,0.462; P<0.001), and age was negatively correlated with physical health (r=-0.371; P<0.001). Family per capita monthly income and social support were positively correlated with mental health (r=0.387,0.525; P<0.001), and anxiety and depression were negatively correlated with mental health (r=-0.403, -0.369; P<0.001). Multiple linear regression analysis showed that age, family per capita monthly income and sleep quality were the influencing factors of the physiological health (P<0.05), and that family per capita monthly income, social support, anxiety and depression were the influencing factors of mental health in elderly MHD patients (P<0.05). Conclusion QoL of elderly MHD patients is suboptimal age; family per capita monthly income, sleep quality, social support, and anxiety and depression are the influencing factors.
