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.
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.
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.
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.
对于预测接受腹膜透析的中国患者饮食依从性的因素，人们了解甚少。我们调查了自我调节疲劳和特质自我控制是否会影响中国腹膜透析患者的饮食依从性。
在两个腹膜透析中心招募了总共192名接受腹膜透析的中国患者。使用自行填写的问卷评估这些患者的饮食依从性、特质自我控制和自我调节疲劳。临床数据从医院病历中提取。使用单因素方差分析分析几个社会人口统计学因素对饮食依从性的显著性，而使用Pearson相关性分析饮食依从性与自我调节疲劳以及特质自我控制之间的关联。使用多变量线性回归分析评估饮食依从性与其他影响因素之间的独立关联。
我们发现腹膜透析患者仅适度遵守饮食处方。盐摄入量（1.89±0.36）、面对困难（2.86±0.26）和液体限制依从性摄入量（2.97±0.30）的依从性最差，位列前三。多变量线性回归分析显示，教育水平（β=0.339，P<0.001）、居住地（β=-0.151，P=0.015）、自我调节疲劳（β=-0.648，P<0.001）和特质自我控制（β=0.118，P=0.022）是饮食依从性的独立预测因素。
教育水平和居住地对中国腹膜透析患者的饮食依从性有强烈影响。另一方面，自我调节疲劳和特质自我控制是腹膜透析患者饮食依从性的独立预测因素。这些发现可为提高腹膜透析患者的饮食依从性提供指导。
