老年肝硬化患者营养状况及其与临床相关因素分析

目的探讨老年肝硬化患者营养状况及与各临床相关因素的关系。方法采用SGA（主观全面评估）、NRS-2002（营养风险筛查）对2009年5月至2010年5月200例住院肝硬化患者进行营养评估和营养风险筛查，分析不同年龄组肝硬化患者营养状况及风险与并发症、住院时间、Child分级及临床各相关因素的关系。结果住院肝硬化患者营养不良发生率、营养风险发生率老年组（≥60岁）均高于非老年组（〈60岁），老年组肝硬化中有营养不良、营养风险的患者住院时间明显长（P〈0．05）；老年肝硬化患者Child分级、并发症发生率在有营养不良、营养风险与无营养不良、无营养风险患者之间比较差异无统计学意义。结论老年肝硬化患者营养不良和营养风险发生率明显增加，住院时间明显延长；在治疗原发病的同时，应对他们给予合理的营养支持。

Prevalence of malnutrition and nutritional risk in elderly liver cirrhosis patients:evaluation of nutritional status and clinical relative factors

Objective To explore the relationship between the nutritional status of hospitalized elderly liver cirrhosis patients and clinical relative factors.Methods Subjective global assessment(SGA) and nutrition risk screen(NRS-2002) were used to identify malnutrition and nutrition risk of 200 liver cirrhosis patients from May 2010 to May 2011retrospectively,then the clinical data of patients from different age groups were compared,and the relationship between nutritional status and Child-pugh score,complications,length of hospital stay and other clinical factors of the hospitalized elderly liver cirrhosis patients was analyzed.Results Overall prevalence of undernutrition and nutritional risk of hospitalized liver cirrhosis as defined by SGA and NRS-2002 was 31.5%% and 53.5% respectively.The prevalence of undernutrition and nutritional risk in elderly liver cirrhosis patients(age≥60 y) was significantly higher than that in younger cases(age<60 y)(39.2% vs 24.3%,66% vs 41.7%,P<0.05).The hospital stay of elderly liver cirrhosis with malnutrition or nutrition risk extended obviously(P<0.05).In aged liver cirrhosis patients,the differences between nutritional risk and no nutrition risk groups were not significant in terms of Child-pugh score and major complications(χ2 = 1.1,0.033,P> 0.05),and so they were between malnutrition and well-nourished elderly liver cirrhosis patients(χ2= 0.525、0.330,P> 0.05).Conclusion The prevalence of undernutrition and nutritional risk in elderly liver cirrhosis patients increase remarkably,and the hospital stay of patients with malnutrition or nutritional risk extends remarkably.
