简易营养评价精法及传统营养评价对老年稳定期慢性阻塞性肺病患者营养状态的评估

目的评估老年稳定期中、重度慢性阻塞性肺病（COPD）患者营养不良的发生率。了解简易营养评价精法（MNA—SF）和传统营养评价的相关性，为MNA—SF临床应用提供依据。方法测量52例老年稳定期中、重度COPD患者的体质指数（BMI），理想体重比（IBW％），三头肌皮皱厚度（TSF），上臂肌围（MAMC），血清白蛋白（ALB），血色素（UB），总淋巴细胞计数（TLC），同时应用传统营养评价法和MNA-SF评估营养不良的发生率。结果营养不良的发生率：传统营养评价人体测量为30．8％-48．1％，实验室检查为19．2％～82．7％。MNA—SF营养不良的检出率为44．2％。MNA—SF与BMI、IBW％、TSF、MAMC有很好的相关性，P〈0．001。结论老年稳定期中、重度COPD患者营养不良发生率用传统营养测量评价为19．2％～82．7％。MNA-SF则为44．2％。MNA-SF是老年人营养评价的可靠方法，简便，适用于临床诊断。

The application of MNA-SF and Classical Nutritional Assessment in the investigation of the nutritional status of the aged patients with chronic obstructive pulmonary disease

Objective To evaluate the nutritional status in the aged patients with stable stage of moderate to severe chro- nic obstructive pulmonary disease （COPD） and confirm the correlation between Short-form Mini-nutritional Assessment （MNA-SF） and Classical Nutritional Assessment in order to provide reference for the clinical application of MNA-SF. Methods Fifty-two aged patients with stable stage of moderate to severe chronic obstructive pulmonary disease （COPD） were investigated with indexes including the body mass index （BMI）, percentage of ideal body weight （IBW%）, triceps skinfold thickness （TSF）, mid-upper arm muscle circumference （MAMC）, serum albumin （ALB）, hemoglobin （HB） and total lymph cell count （TLC）. Meanwhile, those patients＇ nutritional statuses were investigated by both MNA-SF and Classical Nutritional Assessment. Results Different assessment methods showed different detection rates of malnutrition, with specific detection rates at 30.8 %-48.1%, 19.2 %-82.7 %, and 44.2 % with Classical Nutritional Assessment, Laboratory Tests, and MNA-SF, respectively. MNA-SF method correlates very well with clinical and laboratory test markers such as BMI, IBW%, TSF, and MAMC （P〈0.001）. Conclusions The detectionrateofmalnutritionbyclassicalnutritional assessment ranged from 19.2% to 82.7%, with its parallel as 44.2% by MNA-SF in the aged patients with stable stage of moderate to severe COPD. MNA-SF is simple but reliable tool to evaluate the nutritional status of the aged patients, thus applicable for clinical practice.
