摘　　要：目的探索微型营养评估简易法(MNA-SF)能否客观、正确地评估老年住院患者的营养状况以及对临床预后进行预测。方法选择2012年3月-4月四川大学华西医院新入院老年患者407例,平均年龄(75.4±7.10)岁,以MNA-SF评估其营养状态并根据营养状态分为两组,随访至出院或住院第30 d,分析其营养状况与住院时间,住院费用,全身炎症反应综合征(SIRS),死亡等临床结局的相关性。结果营养不良者22.6%(92例),营养不良风险者31.9%(130例),营养状态良好者45.5%(185例)。其中34例营养不良者,18例营养不良风险者和4例营养良好者发生SIRS;另有11例营养不良者,7例营养不良风险者和1例营养良好者死亡。MNA-SF分值在0～7分的患者无论在发生SIRS还是临床不良结局方面显著高于分值为8～14分的患者(P<0.05)。营养不良者住院时间为(14.6±8.30)d,营养不良风险或营养良好者为(12.1±7.99)d,差异具有统计学意义(P<0.05)。结论 MNA-SF是一可靠,简便易行,可以预测老年住院患者临床预后的营养评估工具。Objective To assess whether mini nutritional assessment-short form（MNA-SF） can evaluate nutrition status of older inpatients correctly and predict their clinical outcomes objectively.Methods This study included 407 older inpatients with an average age of（75.4 ± 7.10） years old from West China Hospital of Sichuan University between March and April 2012.The nutritional state of the patients were assessed with MNA-SF until discharge from hospital or the 30th day during the follow-up.We analyzed the association between nutritional status assessed by MNA-SF and length of hospital stay（LOS）,hospital costs,systemic inflammatory response syndrome（SIRS）,and mortality.Results Among all included patients,there were 22.6%（n=92） malnourished,31.6%（n=130） at risk of malnutrition,and 45.5%（n=185） nourished.And 37%（n=34） of the malnourished,13.8%（n=18） of the patients at risk of malnutrition and 2.2%（n=4） of the nourished patients suffered from SIRS.Furthermore,12.0%（n=11） of malnourished,5.4%（n=7） of patients at risk of malnutrition and 0.5%（n=1） of nourished patients died.Patients with a MNA-SF score less than 8 points had higher incidence of SIRS and mortality,compared with patients with a MNA-SF score of 8 or more than 8 points（P〈0.055）.LOS of malnourished patients was （14.6 ± 8.30） days,while LOS of patients at risk of malnutrition or nourished status was 12.1 ± 7.99 days which were significantly shorter（P〈0.055）.Conclusion MNA-SF may be a reliable,simple tool,and can predict the prognosis of older inpatients.
