中文摘要：

目的：用NRS2002对住院COPD病人进行营养风险筛查，探讨NRS2002营养风险筛查结果与体格检查指标和生化指标的相关性。方法：随机抽取2015年1月～2015年12月入院住院的COPD病人218例，用NRS2002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NRS2002营养风险筛查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病人中存在营养风险者（NRS2002≥3分）69例，发生率31．7％，不同年龄段和不同肺功能分级病人间营养风险发生率差异有统计学意义（P〈0．05）。NRS2002营养风险筛查结果与2个体格检查指标（BMI和FFMI）和2个生化指标（ALB和PA）存在关联性（P〈0.05）。结论：住院COPD病人营养风险发生率较高，老年病人尤甚。NRS2002适合作为住院COPD病人营养风险筛查工具，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。

英文摘要：

Objective： To explore the potential relationship between nutritional risk evaluated by NRS 2002 and the indexes of physical and biochemical parameters. Methods： From January 2015 to December 2015, 218 hospitalized patients with chronic obstructive pulmonary disease （COPD） were randomly selected to assess the nutrition risk by using NRS 2002, and the physical examination indexes and biochemical indicators were also collected. The potential correlations between NRS 2002 score and the physical and biochemical parameters were analyzed. Results： The incidence of nutritional risk （the score of NRS 2002 ≥ 3） was 31.7% in 218 COPD inpatients. Both age and pulmonary function was significantly related to the incidence of nutritional risk （P 〈 0.05）. The relevance also was found between NRS 2002 score and 2 physical indexes （BMI and FFMI） and 2 biochemical indicators （ALB and PA）, Conclusion： The frequency of nutritional risk is very high among hospitalized patients with COPD, especially in old patients. NRS 2002 is a suitable nutritional risk screening tool in COPD patients, but a comprehensive nutrition assessment should combine proper nutritional risk screening tool with physical examination indexes and biochemical indicators in clinical applications.
