目的 应用2002年欧洲肠外肠内营养学会发布营养不良筛查指南(NRS-2002)调查住院慢性阻塞性肺疾病(COPD)患者营养不良发生情况,探讨NRS-2002营养评价结果与体格检查指标和生化指标的相关性.方法 随机抽取COPD患者218例,用NRS-2002进行营养风险筛查,同时进行体格检查,计算对应指标,测定血生化指标,分析NRS-2002营养评价结果与体格检查指标和生化指标的相关性.结果 218例住院COPD患者营养不良(NRS-2002≥3分)发生率31.7%,不同年龄段和不同肺功能分级患者间营养不良发生率存在统计学差异(P<0.05).NRS-2002营养评价结果与2个体格检查指标〔体质指数(BMI)和去脂体重指数(FFMI)〕和2个生化指标〔白蛋白(ALB)和前白蛋白(PA)〕存在关联性(P<0.05).结论 住院COPD患者营养不良发生率较高,老年患者尤甚.NRS-2002适合作为住院COPD患者营养风险筛查工具,但在临床应用中应结合体格检查指标和生化指标进行全面综合营养评估.“,”Objective To investigate the prevalence of malnutrition among COPD inpatients and explore the relationship between NRS-2002 and indexes of physical examination and biochemical indicators.Methods From January 2015 to December 2015, 218 COPD hospital patients were randomly selected to survey the nutrition status by NRS-2002, and obtain the related physical examination indexes and biochemical indicators.Simultaneously the relevance was analyzed between NRS-2002 and indexes of physical examination and biochemical indicators.Results The incidence rate of malnutrition (the score of NRS-2002≥3) were 31.7% among 218 COPD inpatients.The significant differences of malnutrition incidence rate were observed among different age brackets and pulmonary function level (P<0.05).The relevance also was observed between NRS-2002 and 2 physical indexes (BMI and FFMI) and 2 biochemical indicators (ALB and PA).Conclusions The incidence rate of malnutrition is very high among inpatients with COPD, especially among old patients.NRS-2002 is a suitable nutritional risk screening tool for COPD patients, but a comprehensive nutrition assessment should combine proper nutritional risk screening tool with physical examination indexes and biochemical indicators in clinical applications.
