(1) Background: Optimal dietary intake is integral to good health in people receiving peritoneal dialysis (PD). We investigated how dietary patterns, dietary adequacy and nutrient intake may change over time in people commencing PD. (2) Methods: Participants were attending the PD training unit for the commencement of peritoneal dialysis, aged ≥18 years and willing to complete food records. Misreporters were excluded from the analysis. Dietary intake was compared at PD commencement and at 12 months. Intake was also compared to reference standards. Dietary patterns were derived using principal component analysis. (3) Results: There were no significant changes between baseline and 12 months for grains, fruit, vegetables and meat. Dairy and added sugar intake was significantly lower ( = 0.01). The intake of energy and protein was adequate and did not change. There was a significant reduction in dietary phosphorus and calcium, and increased vitamin C intake. Three dietary patterns were identified: the 'Bread and Cereal' pattern; 'Milk and Potatoes' pattern; and the 'Semi Vegetarian' pattern. (4) Conclusions: In this longitudinal cohort study, the diet quality was suboptimal and there were limited changes in intake after the commencement of PD. Further exploration of how dietary patterns may impact outcomes and quality of life is warranted.
(1) 背景：最佳饮食摄入对于接受腹膜透析（PD）的人群的健康至关重要。我们研究了开始腹膜透析的人群的饮食模式、饮食充足性和营养摄入如何随时间变化。(2) 方法：参与者为参加腹膜透析培训单元开始腹膜透析的患者，年龄≥18岁且愿意完成食物记录。误报者被排除在分析之外。比较了腹膜透析开始时和12个月时的饮食摄入量。摄入量也与参考标准进行了比较。使用主成分分析得出饮食模式。(3) 结果：谷物、水果、蔬菜和肉类在基线和12个月之间没有显著变化。乳制品和添加糖的摄入量显著降低（P = 0.01）。能量和蛋白质的摄入量充足且没有变化。饮食中的磷和钙显著减少，维生素C摄入量增加。确定了三种饮食模式：“面包和谷物”模式；“牛奶和土豆”模式；以及“半素食”模式。(4) 结论：在这项纵向队列研究中，饮食质量欠佳，腹膜透析开始后摄入量变化有限。有必要进一步探讨饮食模式如何影响结局和生活质量。
