Abstract

Objective

Hemodialysis (HD) patients face challenges in upholding dietary compliance. This study aimed to compare dietary intake against disease-specific guidelines. Secondary, to assess the overall diet quality and to explore the association between dietary potassium intake and serum potassium concentrations.

Methods

In this cross-sectional multicenter study, nutrient intake of Dutch adult HD patients was assessed using food frequency questionnaires and diet quality with the Dutch Healthy Diet 15-index. Intake and diet quality were compared to disease-specific dietary recommendations or Dutch Dietary Guidelines. Insufficient intake was defined as <90% of the requirement, sufficient as 90-100%, and excessive as >110%. The association between serum potassium concentration and dietary potassium intake was modeled with linear regression analysis.

Results

The study population consisted of 248 participants (60% male) from 21 dialysis centers. Energy intake (1789 [872] kcal/day) was insufficient for 45% of the participants, while protein intake (1 [0.5] g/kg/d) was insufficient for 50%. Despite 67% of participants managing to align their energy intake below 110% of the recommended level, a high prevalence of overweight (61%) was observed in this cohort. Saturated fat intake was excessive for 87% of participants, while only 15% met the recommended fiber intake. Overall diet quality was low (74 [20] maximum score of 150). No association was observed between serum potassium and dietary potassium intake after adjusting for relevant confounders (r = 0.163, P = .261).

Conclusions

A considerable proportion of Dutch HD patients were unable to meet disease-specific dietary guidelines. Diet quality was shown to be poor.

血液透析患者的营养摄入和饮食质量：有待改善的范围。

目的：血液透析（HD）患者在维持饮食依从性方面面临挑战。这项研究的目的是比较饮食摄入量和疾病特异性指南。其次，评估整体饮食质量，探讨膳食钾摄入量与血清钾浓度之间的关系。方法：在本横断面多中心研究中，采用食物频率问卷（FFQs）评估荷兰成年HD患者的营养摄入，并采用荷兰健康饮食15指数（DHD15-index）评估饮食质量。将摄入量和饮食质量与疾病特定饮食建议或荷兰饮食指南进行比较。摄入不足的定义为110%。血清钾浓度与饲粮钾摄入量之间的关系采用线性回归分析。结果：研究人群包括来自21个透析中心的248名参与者（60%为男性）。45%的参与者能量摄入（1789[872]千卡/天）不足，50%的参与者蛋白质摄入（1[0.5]克/公斤/天）不足。尽管67%的参与者设法将他们的能量摄入控制在推荐水平的110%以下，但在该队列中观察到超重的高患病率（61%）。87%的参与者饱和脂肪摄入量过高，而只有15%的参与者达到了建议的纤维摄入量。总体饮食质量较低（74桶，最高得分为150）。校正相关混杂因素后，血清钾和膳食钾摄入量之间无相关性（r= 0.163， P= 0.261）。结论：相当比例的荷兰HD患者无法满足特定疾病的饮食指南。饮食质量很差。
