Abstract:
Objective To explore overweight and obesity on pulmonary function,exercise tolerance,quality of life in COPD.Methods Patients with COPD were divided into three groups:normal body mass index (BMI) (n =43),overweight (n =34) and obese (n =36).Resting pulmonary function test,cardiopulmonary exercise test (CPET) and St George' s respiratory questionnaire (SGRQ) scores were compared during all three classes of BMI.SPSS13.0 software was used.Results Normal BMI patients (47.28±3.82)％ had less FEV1/FVC compared to overweight ( 52.50 ± 8.23 ) ％ and obese (53.20 ± 8.30) ％,and the difference has statistically significance (F =8.76,P ＜0.01 ).There were significant differences in FEV1/FVC between normal BMI patients and obese (P ＜ 0.01 ),normal BMI patients and overweight(P ＜ 0.01 ),but not between obese and overweight (P ＞ 0.05) by multiple comparison.VO2 max/kg in normal group was (21.80 ± 3.67 ) ml · kg-1 · min-1,(20.19 ±4.14) ml · kg 1 · min- 1 in overweight group and (18.98 ± 3.22)ml · kg-1 · min-1 in obese group,and the differences among the three group were significant (F =5.82,P ＜ 0.01 ).Multiple comparison showed no difference between normal and overweight ( P ＞ 0.05 ),between overweight and obese group (P ＞ 0.05 ),but difference was significant between normal and obese (P ＜0.05) ; There was no difference in SGRQ score (P ＞0.05).Conclusions Weight excess may improve the airflow obstruction of resting pulmonary function test,but exercise tolerance and the airflow obstruction of CPET were worse in obese and overweight.
