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

Abstract

Background: Inadequate nutrition is common for both sarcopenia and frailty. We investigated whether hemodialysis patients with sarcopenia and frailty have reduced dietary intakes. Methods: Dietary intake, and physical activity were analyzed, along with body composition and relevant clinical data. Results: 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%, X2 4.6, p =.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], p =.017], body mass index [OR 0.84, 95% CI [0.71, 0.99], p =.042] and lack of exercise [OR 7.62, 95% CI [1.16, 50.29], p =.035]. Frailty was associated with female gender [OR 17.79, 95% CI [2.09, 151.59], p =.008], age [OR 1.13, 95% CI [1.04, 1.22], p =.006], and dialysis vintage [OR 1.55, 95% CI [1.06, 2.26], p =.024]. Conclusion: 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.
