Periodic assessment of dietary intake across a given dialysis population may help to improve the clinical outcomes related to nutrients such as dietary protein, phosphorus, or potassium. Although dietary recalls and food records are used to assess dietary intake at individual level and over shorter periods, food frequency questionnaires (FFQ) are used to rank subjects of a given population according to their nutrient intake over longer periods.
To modify and refine the conventional Block FFQ to develop a specific FFQ for dialysis patients.
A total of 8 DaVita outpatient dialysis clinics in Los Angeles area, which participated in the "Nutrition and Inflammation in Dialysis Patients" study.
The study included 154 patients undergoing maintenance hemodialysis (MHD).
Dietary intake of participating MHD patients using a 3-day food record, supplemented by a person-to-person dietary interview, to capture food intake over the last hemodialysis treatment day of the week and the 2 subsequent nondialysis days.
Analyses of the food records identified the key contributors to the daily nutrient intake in the 154 participating MHD patients. A "Dialysis-FFQ" was developed to include approximately 100 food items representing the total food intake of 90% of the patients of the "Nutrition and Inflammation in Dialysis Patients" study population. Distinctions were made in several food items on the basis of key nutritional issues, such as protein, phosphorus, and potassium, in dialysis patients.
We have developed a "Dialysis FFQ" to compare and rank dialysis patients according to their diverse nutrient intake. Although the Dialysis-FFQ may be a valuable tool to compare dialysis patients and to identify those who ingest higher or lower amounts of a given nutrient, studies are needed to examine the utility of the Dialysis-FFQ for nutritional assessment of dialysis patients.
定期评估特定透析人群的饮食摄入情况，有助于改善与营养素相关的临床结局，如膳食蛋白质、磷或钾。尽管饮食回忆和食物记录用于评估个体和较短时间内的饮食摄入情况，但食物频率问卷（FFQ）用于根据特定人群的营养素摄入情况对其进行排名。
修改和完善传统的 Block FFQ，为透析患者开发特定的 FFQ。
洛杉矶地区的总共 8 家 DaVita 门诊透析诊所，参与了“透析患者的营养与炎症”研究。
该研究包括 154 名接受维持性血液透析（MHD）的患者。
使用 3 天食物记录和面对面的饮食访谈，记录参与 MHD 患者的饮食摄入情况，以捕获上周血液透析治疗日和随后的 2 天非透析日的食物摄入情况。
对食物记录的分析确定了 154 名参与 MHD 患者的日常营养素摄入的主要贡献者。开发了“透析-FFQ”，其中包含大约 100 种食物，代表“透析患者的营养与炎症”研究人群的 90%患者的总食物摄入量。根据透析患者的关键营养问题，如蛋白质、磷和钾，对几种食物进行了区分。
我们已经开发了一种“透析 FFQ”，用于比较和根据患者的不同营养素摄入量对透析患者进行排名。尽管透析-FFQ 可能是比较透析患者并识别摄入特定营养素较多或较少的患者的有价值工具，但需要进一步研究来检验透析-FFQ 用于评估透析患者营养状况的效用。
