Comparison Between Semi-Quantitative Frequency Methods and 7-day Dietary Records Methods in Food and Nutrition Intake Status For Hemodialysis Patients

Abstract

Objectives: The valid assessment of food and nutrients intakes using appropriate dietary intake method is necessary to improve the nutritional status of the hemodialysis (HD) patients. This study was conducted to compare the method between newly developed, semi-quantitative food frequency questionnaire (Semi-FFQ) and 7-day dietary records (7-DRs) for hemodialysis patients. Methods: We conducted both methods on 53 maintenance HD patients in two university hospitals. We calibrated the frequency, portion size and daily intake of 47 food items reported in Semi-FFQ. The food and nutrients intake was compared and the correlation of the two methods was analyzed. Also each nutrient intake was compared to recommended dietary allowance for Korean (KDRIs) and recommended nutrient reference value for HD patients. Results: Energy and energy-yielding nutrients intakes were significantly higher in the two methods (p<0.01). These support the possible reliability between Semi-FFQ and 7-DRs that is similar with regard to most mineral and vitamin intakes. Thus, the Semi-FFQ used in this study for the assessment of nutrient intakes of HD patients can be reliable for the assessment of the nutrient intake along with the 7-DRs. The correlation coefficients were higher for foods consumed daily, such as steamed rice, meat and chicken, bean, egg, milk, coffee and alcohol than for those of foods eaten rarely (p<0.01). Conclusions: The Semi-FFQ used in this study can be a reliable tool for the assessment of the HD patients' nutrient intake along with the 7-DRs, despite its limitations.

Comparison of dietary intake patterns in hemodialysis patients by nutritional status: A cross-sectional analysis

“…Moreover, these patients drank 589.06 mL/d of water on average, and their intake of sodium, potassium, and phosphorus were 3,285.86, 1,856.91, and 760.61 mg/d, respectively, meaning that they consumed more sodium and potassium but less water and phosphorus than the KDOQI recommends. These results are similar to those of another study about nutrition in HD patients published in Korea in 2017 (energy intake: 1,411 ± 410.5 kcal, protein intake: 55.53 ± 21.84 g/d in this study vs energy intake: 1,496 ± 401.7 kcal, protein intake: 58.28 ± 23.06 g/d in the earlier study) [22]. We found no significant differences in the intake of total energy or the major nutrient components (carbohydrates, lipids, and proteins) between the well-nourished and poorly nourished www.krcp-ksn.org groups.…”

Comparison of hemodialysis and peritoneal dialysis patients’ dietary behaviors

“…First, we did not use a diet diary for a complete nutrient assay. Although the Semi-FFQ, which was used in this study, was validated elsewhere [15], there were several limitation of questionnaire itself. FFQ can be underestimated because of the inadequate coverage of all available food items to an individual.…”

“…Recently, the Semi-FFQ has been used for the assessment of nutritional intake in dialysis patients [14]. We designed the semi-FFQ for Korean dialysis patient and reported that this questionnaire would be a reliable tool for the assessment of the HD patients' nutrient intake along with the 7-day dietary record [15]. The correlation coefficients were higher for foods consumed daily, such as steamed rice, meat and chicken, bean, egg, milk, coffee and alcohol, while those were lower in foods eaten rarely.…”
