摘要： 目的探讨主观全面评估法（SGA）评估慢性阻塞性肺疾病（COPD）患者营养状况的价值。方法选取 122 例COPD 稳定期患者，根据SGA 评分结果分为SGA-A（营养良好）组21 例、SGA-B（轻-中度营养不良）组57 例及SGA-C（重度营养不良）组44 例。测定并比较3 组的身体测量指数、生化指标、肺功能、COPD 评估测试（CAT）及穿梭行走测试（SWT），分析这些指标与SGA 评分的相关性。结果SGA-B 组、SGA-C 组的体质指数（BMI）、上臂肌围（AMC）和FEV1 占预计值的百分比（FEV1% Pred）均低于SGA-A 组（P < 0.05），SGA-B 组与SGA-C 组的差异无统计学意义；肱三头肌皮褶厚度（TSF）SGA-C 组＜SGA-B 组＜SGA-A 组，CAT 评分SGA-C 组＞SGA-B 组＞SGA-A 组（P < 0.05）；SGA-C 组的增量穿梭行走测试（ISWT）距离、耐力穿梭行走测试（ESWT）速度低于SGA-A 组（P < 0.05）；3 组的生化指标及第1 秒用力呼气量（FEV1）/用力肺活量（FVC）无明显差异（P＞0.05）。SGA 评分与身体测量指数、FEV1% Pred 及运动能力指标呈负相关，与CAT 评分呈正相关，与FEV1/FVC 及生化指标无相关性。结论 SGA 与身体测量指数、FEV1% Pred、CAT 及SWT 具有相关性，可作为COPD 患者营养评估的有效工具。

Abstract: Objective To explore the subjective global assessment (SGA) to evaluate the nutritional status of patients with chronic obstructive pulmonary disease(COPD). Methods Patients with stable COPD (n=122) were included and divid⁃ ed into three groups base on their SGA scores: SGA-A (n=21), SGA-B (n=57), SGA-C (n=44). Nutritional status of all pa⁃ tients was assessed by SGA. Anthropometric measurement, biochemical test, pulmonary function test, COPD assessment test (CAT) and shuttle walking test (SWT) were studied between all three groups to search statistical significance and correlation with SGA. Results Body mass index(BMI), arm muscle circumference (AMC) and forced expiratory volume in the first sec⁃ ond % of predicted (FEV1% Pred) were all lower in SGA-B and SGA-C than those in SGA-A(P < 0.05)，there were no statis⁃ tical differences of these parameters between SGA-B and SGA-C. Triceps skin fold (TSF) was lower in SGA-C than that in SGA-B than that in SGA-A, while CAT score is the reverse order (P < 0.05). The walking distance of incremental shuttle walking test (ISWI) and the endurance time of endurance shuttle walking test (ESWI) were lower in SGA-C than that in SGA-A (P < 0.05). There were no statistical differences of forced expiratory volume in the first second (FEV1)/forced vital ca⁃ pacity(FVC), biochemical parameters between all three groups. SGA scores correlated positively with CAT and negatively with anthropometric parameters, FEV1% Pred and SWT (P < 0.05). However no correlations was deduced between SGA scores with FEV1/FVC and biochemical parameters. Conclusion SGA scores correlated with anthropometric parameters, FEV1% Pred, CAT and SWT. SGA is an effective method to assess the nutritional status in patients with stable COPD.
