上下文 营养不良是经常观察到的恶性疾病住院患者，并可能导致更长的住院时间。 目的 比较恶性肿瘤患者与非恶性肿瘤患者的营养状况、淋巴细胞计数、血红蛋白值及住院时间。 方法 这项比较研究评估了928名患有和不患有恶性疾病的手术患者（50.2%女性和49.8%男性）的营养状况指标，即体重指数、近期体重减轻、淋巴细胞计数、血红蛋白和住院时间。使用卡方检验比较两组之间的比例，使用Mann-Whitney检验比较两组之间的连续测量值。显著性水平设定为5%。 结果 恶性肿瘤患者住院时间较长（P<0.0001），体重指数<18.5（P<0.0001）和近期体重变化（P<0.0002）的恶性肿瘤患者比例较高。淋巴细胞计数在两组之间也存在统计学差异（P = 0.0131），恶性疾病患者的淋巴细胞计数水平较低。 结论 淋巴细胞计数、血红蛋白值和体重下降是恶性疾病患者营养耗竭的重要指标。
CONTEXT Malnutrition is frequently observed in inpatients with malignant diseases and may contribute to longer hospital stays. OBJECTIVE To compare the nutritional status, lymphocyte count, hemoglobin values and length of hospital stay of patients with and without malignant diseases. METHODS This comparative study assessed indicators of nutritional status, namely body mass index, recent weight loss, lymphocyte count, hemoglobin and length of hospital stay, of 928 surgical patients with and without malignant diseases (50.2% females and 49.8% males). The chi-square test was used to compare proportions and the Mann-Whitney test was used to compare continuous measurements between two groups. The significance level was set at 5%. RESULTS Patients with malignant diseases had longer hospital stays (P<0.0001), furthermore, a higher percentage of patients with malignant diseases had body mass index <18.5 (P<0.0001) and experienced recent weight changes (P<0.0002). Lymphocyte count also differed statistically between the groups (P = 0.0131), which lower levels were identified among patients with malignant diseases. CONCLUSION The lymphocyte count, hemoglobin values and weight loss are important findings of nutritional depletion in patients with malignant diseases.
