摘　　要：Objective The aim of this study was to determine whether low calf circumference(CC) could predict nutritional risk and the cutoff values of CC for predicting nutritional risk in hospitalized patients aged ≥ 80 years.Methods A total of 1,234 consecutive patients aged ≥ 80 years were enrolled in this study.On admission, demographic data, CC, and laboratory parameters were obtained.Patients with Nutritional Risk Screening 2002(NRS-2002) total score ≥ 3 were considered as having nutritional risk.Results CC values were significantly lower in patients with nutritional risk compared to those in patients without nutritional risk [27.00(24.50-31.00) vs.31.00(29.00-33.50], P < 0.001].CC was negatively correlated with age and nutritional risk scores.Logistic regression analysis of nutritional risk revealed that body mass index, albumin level, hemoglobin level, cerebral infarction, neoplasms, and CC(OR, 0.897;95% confidence interval, 0.856-0.941;P < 0.001) were independent impact factors of nutritional risk.Nutritional risk scores increased with a decrease in CC.In men, the best CC cutoff value for predicting nutritional risk according to the NRS-2002 was 29.75 cm.In women, the cutoff value was 28.25 cm.Conclusion CC is a simple, noninvasive, and valid anthropometric measure to predict nutritional risk for hospitalized patients aged ≥ 80 years.Objective The aim of this study was to determine whether low calf circumference(CC) could predict nutritional risk and the cutoff values of CC for predicting nutritional risk in hospitalized patients aged ≥ 80 years.Methods A total of 1,234 consecutive patients aged ≥ 80 years were enrolled in this study.On admission, demographic data, CC, and laboratory parameters were obtained.Patients with Nutritional Risk Screening 2002(NRS-2002) total score ≥ 3 were considered as having nutritional risk.Results CC values were significantly lower in patients with nutritional risk compared to those in patients without nutritional risk [27.00(24.50-31.00) vs.31.00(29.00-33.50], P < 0.001].CC was negatively correlated with age and nutritional risk scores.Logistic regression analysis of nutritional risk revealed that body mass index, albumin level, hemoglobin level, cerebral infarction, neoplasms, and CC(OR, 0.897; 95% confidence interval, 0.856-0.941; P < 0.001) were independent impact factors of nutritional risk.Nutritional risk scores increased with a decrease in CC.In men, the best CC cutoff value for predicting nutritional risk according to the NRS-2002 was 29.75 cm.In women, the cutoff value was 28.25 cm.Conclusion CC is a simple, noninvasive, and valid anthropometric measure to predict nutritional risk for hospitalized patients aged ≥ 80 years.
