慢性阻塞性肺疾病患者日常活动状况及相关因素分析

目的描述稳定期COPD患者的日常活动状况并分析其相关因素。方法在北京两所医院呼吸科门诊选取稳定期COPD患者94例,用PFSDQ-M评估其活动受限、活动后呼吸困难和疲乏情况。结果患者的日常活动为轻度到中度受限,活动后呼吸困难和疲乏程度为轻度到中度。活动受限、活动后呼吸困难和疲乏程度分别与6min步行距离、FEV1、FEV1/FVC、MMRC呼吸困难程度及BODE指数呈显著性相关(r=-0.27-0.60,P0.01)。MMRC呼吸困难评分可解释26%日常活动受限的变化。结论稳定期的COPD患者日常活动轻度受限,重度患者活动明显受限。呼吸困难是日常活动受限主要的影响因素。

The status and related factors of daily activities in patients with chronic obstructive pulmonary disease

Objective To determine relationships between daily activities measured as modified version of Pulmonary Functional status and Dyspnea Questionaire (PFSDQ-M) and functional capacity and symptoms experienced in patients with chronic obstructive pulmonary disease (COPD). Methods Convenience sample of 94 COPD patients with stable condition were assessed by interview with PFSDQ-M Chinese version and modified Medical Research council dyspnea scale (MMRC) respectively. Pulmonary function test (PFT) and 6-minute walking test (6MWT) were undergone on the same day or within one week as interview. PFSDQ-M has three subscales,i.e.,change experienced by patient with activities (CA),dyspnea with activities (DA) and fatigue with activities (FA). Results Scores of CA,DA and FA correlated to 6-minute walking distancer= (-0.37)- (-0.42),FEV_1 r=(-0.27)-(-0.32),FEV_1/FVC r= (-0.27)- (-0.32),dyspnea rated by MMRC (r=0.55-0.60) and BODE index (r=0.35-0.40),respectively (all P<0.01). dyspnea explained 26% of the variance in changes of activities. Conclusions Physical activities moderately changed in patients with stable COPD;Dyspnea is the best predictor of limitation of daily activities.
