- W2389571911 abstract "Objective To evaluate the correlation between dyspnea,exercise capacity and quality of life.Methods 108 patients with stable COPD recruited from May 2009 to April 2011 were calculated for body mass index(BMI),pulmonary function and evaluated for the severity of dyspnea,exercise capacity and quality of life.Measurement data were represented by ±s,and linear correlation analysis was used.All parameters were normally distributed except for dyspnea rating data.Therefore,Spearman rank correlation was used for dyspnea and quality of life,and Pearson product moment correlation for the others.The result of P0.05 was considered to be significantly different.Results Dyspnea and exercise capacity were strongly correlated with quality of life(r=0.749 and 0.676,P0.05).For lung function,forced expiratory volume in 1s(FEV1)and forced vital capacity(FVC)were correlated with quality of life,but weak(r=0.355 and 0.341,P0.05).No statistical significance was found in the correlation between BMI and exercise capacity.Taking BMI,FEV1%,FVC%,dyspnea and exercise capacity as independent variables,quality of life score as a dependent variable,multiple stepwise regression analysis was conducted,showing that dyspnea and exercise capacity were independently associated with quality of life and became a main factor affecting the quality of life.Conclusions Dyspnea and exercise capacity can better evaluate the quality of life in patients with COPD than spirometry-derived parameters." @default.
