Does Dietary Intake Differ in Kidney Failure Patients With Sarcopenia and Frailty Treated by Hemodialysis.

Inadequate nutrition is common for both sarcopenia and frailty. We investigated whether hemodialysis patients with sarcopenia and frailty have reduced dietary intakes. Dietary intake, and physical activity were analyzed, along with body composition and relevant clinical data. We studied 51 hemodialysis patients; 52.9% male, age 60 ± 15 years; 33.3% sarcopenic, and 72.5% frail. Dietary protein and calories were similar for sarcopenic and non-sarcopenic patients 0.68 (0.38-3.5) vs. 0.68 (0.18-2.9) g protein/kg/day and 19.2 (8.2-77.5) vs. 15.2 (6.2-38.5) kcal/kg/day. More sarcopenic patients had low physical activity (88.2% vs. 58.8%, 4.6,  = .03). Frail and non-frail patients had similar intakes 0.67 (0.28-3.5) versus 0.83 (0.18-1.6) g protein/kg/day and 15.5 (8.1-77.5) vs. 18.8 (6.2-45.4) kcal/kg/day. Sarcopenia was associated with age [Odds ratio (OR) 1.09, 95% confidence interval (CI) [1.02, 1.18],  = .017], body mass index [OR 0.84, 95% CI [0.71, 0.99],  = .042] and lack of exercise [OR 7.62, 95% CI [1.16, 50.29],  = .035]. Frailty was associated with female gender [OR 17.79, 95% CI [2.09, 151.59],  = .008], age [OR 1.13, 95% CI [1.04, 1.22],  = .006], and dialysis vintage [OR 1.55, 95% CI [1.06, 2.26],  = .024]. Hemodialysis patients with sarcopenia and frailty did not have lower dietary protein and calorie intake. Frailty was associated with age and sarcopenia with a sedentary lifestyle.
