急性卒中患者住院期间营养不良的危险因素分析

Predictors of Poor Nutritional Status in Acute Stroke Patients

目的分析急性卒中患者住院期间营养不良的危险因素。方法收集住院的连续的急性首发卒中患者。以白蛋白＆lt;35g/L判定为营养不良,分析相关危险因素。结果急性卒中患者286例,入院时营养不良率为5.9%,到第2周时为19.9%。入院时年龄、白蛋白水平、吞咽困难为急性卒中患者住院期间发生营养不良的独立危险因素[优势比（Oddsratio,OR）分别为1.05、1.395和3.158]。结论入院时有营养不良或吞咽障碍的高龄卒中患者,在住院期间更易发生营养不良。

Objective To identify important predictors of poor nutritional status in acute stroke patients. Methods Consecutive hospitalized patients with acute first-ever stroke were recruited. The risk factors for malnutrition defined as the level of serum albumen below 35g/1 were analyzed. Results Among 286 acute strokes, the prevalence of malnutrition at admission was 5.9%. This figure increased to 19.9% at two weeks later. A logistic regression analysis showed that age, serum albumen level and swallow ability at admission independently predicted malnutrition during hospitalization （OR was 1.05, 1.39 and 3.16, respectively）. Conclusion The elder stroke patients with baseline malnutrition or dysphagia were more likely to be malnutrition.
