Objective: To explore the current status and influencing factors of dietary restriction burden in maintenance hemodialysis(MHD) patients, and to provide evidence for developing targeted interventions for patients with end-stage renal disease(ESRD).Methods: Using convenience sampling, ESRD patients who received MHD in our hospital from May 2023 to May 2025 were recruited. They were surveyed with a general information questionnaire, the Chinese version of the Burden of Dietary Restrictions for Patients with Chronic Disease(BIRD) scale, the Patient Activation Measure(PAM), the Trait Emotional Intelligence Questionnaire-Short Form(TEIQue-SF), and the Fear of Progression Questionnaire-Short Form(FoP-Q-SF). Pearson correlation analysis was performed to evaluate the relationships between the BIRD score and the PAM, TEIQue-SF, and FoP-Q-SF scores. Multiple linear regression analysis was used to identify influencing factors of the BIRD score in MHD patients. Results: The mean scores among MHD patients were 33.37±6.98 for BIRD, 26.40±7.36 for PAM, 86.84±14.30 for TEIQue-SF, and 51.56±12.32 for FoP-Q-SF. BIRD scores were significantly higher among females, patients aged 18-40 years, those with a dialysis duration >3 years, those with an education level of junior high school or below, those without residual renal function, and those who were unemployed(all P<0.05). Pearson analysis showed that the BIRD score was negatively correlated with the PAM score(r=-0.705, P<0.05) and the TEIQue-SF score(r=-0.570, P<0.05), and positively correlated with the FoP-Q-SF score(r=0.642, P<0.05). Multiple linear regression analysis revealed that female sex, age 18-40/41-60 years, dialysis duration >3 years, education of junior high school or below, absence of residual renal function, unemployment, and a high FoP-Q-SF score were risk factors for dietary restriction burden(β>0, P<0.05), whereas high PAM and high TEIQue-SF scores were protective factors(β<0, P<0.05).Conclusion:A high level of dietary restriction burden is prevalent among MHD patients, and the burden is greater among females, younger patients, those with longer dialysis durations, and those with lower educational levels. Clinical attention should focus on these subgroups, and systematic intervention strategies should be implemented to enhance patient activation and emotional regulation, alleviate fear of disease progression, and thereby reduce dietary restriction burden and promote long-term treatment adherence and quality of life. |
