Abstract

<p>【Objective】The aim of this study was to examine the dietary intake and nutritional status of chronic hemodialysis patients with sarcopenia. 【Subjects】Ninety hemodialysis patients (mean age : 62.8±1.2 yrs) were enrolled in this study. 【Methods】We screened the subjects for sarcopenia using the diagnostic criteria developed by the European Working Group on Sarcopenia in Older People. Three nutritional assessments were conducted : the malnutrition-inflammation score (MIS), the geriatric nutritional risk index (GNRI), and a diagnostic assessment for protein energy wasting (PEW), and we completed the food frequency questionnaire for all patients. 【Results】The prevalence of sarcopenia was 22%. The MIS, GNRI, and PEW exhibited sensitivity values of 35%, 50%, and 10%, respectively, for detecting sarcopenia. Multivariate analysis showed that age (odds ratio (OR) : 1.12, 95% confidence interval (CI) : 1.05-1.21, p<0.001) and low protein intake (OR : 0.37, 95%CI : 0.19-0.88, p=0.022) were associated with sarcopenia. The sarcopenic patients consumed significantly less beans (31±11 g vs. 61±6 g, p=0.014) ; fish and meat (110±15 g vs. 153±8 g, p=0.006) ; and confectionery, beverages, and sugar (126±77 g vs. 306±41 g, p=0.006) than the non-sarcopenic patients. 【Conclusion】Sufficient protein intake and calorie intake are essential for preventing sarcopenia. In patients without an appetite, the intake of confectionery, beverages, or sugar might be necessary to prevent muscle loss. However, malnutrition-related sarcopenia was only seen in 10-50% of sarcopenic hemodialysis patients. It is important to assess the muscle strength and muscle function of hemodialysis patients because the use of nutritional measurements alone is not sufficient for screening for sarcopenia.</p>
