Evaluation of the relationship between dietary energy and protein intakes and anthropometric measurements in hemodialysis patients.

This study evaluated the relationship between dietary energy, and protein (animal and plant based) intakes and anthropometric measurements in maintenance hemodialysis (MHD) patients. Individuals between the ages of 19 to 65 who received MHD treatment for more than 3 months from October 2021 to February 2022 in the state hospitals were included in the study. Body mass index (BMI) (kg/m2) was calculated for each patient, and anthropometric measurements including upper middle arm circumference, triceps skinfold thickness (TST) and hand grip strength (HGS) were carried out. 3-day food records and Subjective Global Assessment (SGA) were used to assess nutritional status of the patients. Of the 51 MHD patients included in the study, 33 (64.7%) were male and 18 (35.3%) were female. The mean age of the patients was 50.37 ±â€…11.55 years, and length of time on MHD was 39.49 ±â€…51.68 months. The mean energy intake of female and male MHD patients was 20.01 ±â€…6.94 and 17.26 ±â€…6.24 kcal/kg/d, respectively. The mean dietary protein intake of female and male MHD patients were 0.84 ±â€…0.35 and 0.78 ±â€…0.30 g/kg/d, respectively. Dry weight (P = .048), BMI (P = .020), TST (P = .013), and HGS (P = .026) of well-nourished and moderately malnourished female MHD patients according to SGA results were found to be lower than in male patients. While the majority of the patients receiving MHD treatment appeared to be well-nourished according to the SGA results, energy and protein intakes obtained from the food records were below the recommended daily dietary intake. These evaluations affected the anthropometric measurements including HGS, BMI, and TST. Therefore, there is a need for more comprehensive clinical studies in which anthropometric measurements, food consumption, biochemical findings and nutritional screening tools are used all together to evaluate nutritional status in MHD patients.
