摘要：Purpose :Little is known about factors that predict dietary adherence among Chinese patients undergoing peritoneal dialysis. 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. © 2021 Gao et al.
