We investigated whether self-regulatory fatigue and trait self-control influence dietary adherence among Chinese patients with peritoneal dialysis.Methods: A total of 192 Chinese patients undergoing peritoneal dialysis were recruited at two peritoneal dialysis centers. The dietary adherence, trait self-control and self-regulatory fatigue of these patients were assessed using self-administered questionnaires. Clinical data were extracted from the hospital medical records. The significance of several social demographic factors on dietary adherence was analyzed using One-way ANOVA was used to analyze, whereas the association between dietary adherence and self-regulatory fatigue as well as trait self-control were analyzed using Pearson correlation. The independence association between dietary adherence and other influencing factors was assessed using Multivariable linear regression analyses.Results: We found that peritoneal dialysis patients only moderately adhere to dietary prescriptions. The top three least adherences were observed for salt intake (1.89± 0.36), face of difficulty (2.86± 0.26) and fluid restriction adherence intake (2.97± 0.30). Multivariable linear regression analysis revealed that education level (β=0.339, P< 0.001), residence (β=− 0.151, P=0.015), self-regulatory fatigue (β= − 0.648, P< 0.001), and trait self-control (β=0.118, P=0.022) were independent predictors of dietary adherence.Conclusion: Education level and residence strongly influence dietary adherence among Chinese peritoneal dialysis patients. On the other hand, Self-regulatory fatigue and trait self-control are independent predictors of dietary adherence among peritoneal dialysis patients. These findings can guide the enhancement of dietary adherence of peritoneal dialysis patients.Keywords: peritoneal dialysis, dietary adherence, trait self-control, self-regulatory fatigue
