体质量指数对慢性阻塞性肺疾病急性加重期预后的影响

目的探讨体质量指数(BMI)对慢性阻塞性肺疾病急性加重期(AECOPD)预后的影响。方法将58例AECOPD患者按BMI值分为A组(BMI<21kg.m-2)32例、B组(BMI≥21kg.m-2)26例,观察2组患者的住院时间、死亡率及AECOPD发作频率。结果 A组患者住院时间明显长于B组[(23±9)d vs(16±7)d,P<0.05],死亡率及AECOPD发作频率均明显高于B组[12.5%vs 3.8%,(1.4±0.7)次.年-1 vs(0.8±0.6)次.年-1,均P<0.05],且更易出现呼吸衰竭。结论低BMI是影响AECOPD患者预后的重要因素之一。

Effect of Body Mass Index on Prognosis of Acute Exacerbation of Chronic Obstructive Pulmonary Disease

Objective To investigate the effect of body mass index（BMI） on the prognosis of acute exacerbation of chronic obstructive pulmonary disease（AECOPD）.Methods Fifty-eight patients with AECOPD were divided into group A（BMI21 kg·m-2,n=32）and group B（BMI≥21 kg·m-2,n=26）.Hospital stay,mortality and AECOPD attack frequency were observed in both groups.Results Compared with group B,hospital stay[（23±9）d vs（16±7）d,P0.05],mortality（12.5% vs 3.8%,P0.05）and AECOPD attack frequency [（1.4±0.7）vs（0.8±0.6）times a year,P0.05]significantly increased in group A.Furthermore,group A was likely to have respiratory failure.Conclusion Low BMI is an important factor influencing the prognosis of AECOPD.
