目的:了解上海地区住院老年病人营养不良的发生率及其对并发症的影响。方法:采用微型营养评估方法(MNA),结合实验室检查、膳食营养素摄入量、临床并发症,对上海市四所医院60岁以上615例住院老年病人进行调查分析。结果:住院老年病人营养不良平均患病率为20.3%,贫血及低清蛋白血症平均发生率分别为41.5%及57.2%。营养不良病人的能量、蛋白质及大多数微量营养素摄入量显著低于营养状况良好者(P<0.05),感染及脏器功能衰竭并发症增加。结论:住院老年病人营养不良发生率、贫血、低清蛋白血症患病率较高,营养不良对临床结局有不良影响。
Objective: To understand the incidence of malnutrition in hospitalized elderly patients in Shanghai and its impact on complications. Methods: A total of 615 hospitalized elderly patients over the age of 60 in four hospitals in Shanghai were surveyed by means of micro-nutrition assessment (MNA) method combined with laboratory tests, dietary nutrient intake and clinical complications. Results: The average prevalence of malnutrition in hospitalized elderly patients was 20.3%. The average incidence of anemia and hypoalbuminemia was 41.5% and 57.2% respectively. Malnourished patients had significantly lower energy, protein and most micronutrient intake than those with good nutrition (P <0.05), and increased complications of infection and organ failure. Conclusion: The prevalence of malnutrition, anemia and hypoalbuminemia in hospitalized elderly patients is high, and malnutrition has an adverse effect on clinical outcome.
