Abstract: 【Abstract】Objective To evaluate the nutritional risk and its related risk factors in hospitalized kidney disease patients. Methods A total of 120 hospitalized patients in the nephrology ward were recruited. Their nutritional risks were evaluated using nutritional risk screening 2002 (NRS2002). Logistic regression
model was used to analyze the risk factors. Results The prevalence of patients at nutritional risk in our nephrology ward was 60.8%. Compared with those without nutritional risk, patients with nutritional risk had lower BMI (t=2.542, P=0.012), lower serum albumin (t=6.155, P<0.001) and higher urina ry protein (Z=- 2.406, P=0.016). Serum albumin (OR=0.643, 95% CI 0.521～0.794, P<0.001) and 24- hour urinary protein (OR=0.264, 95% CI 0.119～0.588, P=0.001) were the risk factors for nutritional risk, and both of them were mutually interacted. Conclusions The prevalence of nutritional risk in hospitalized patients in
our department was relatively high. Proteinuria was a risk factor for nutritional risk that may cause poor outcome. Regular nutritional screening and early intervention are required for these patients.
