Abstract：【Objective】 To investigate the influencing factors of physical activities in elderly patients with chronic obstructive pulmonary disease (COPD). 【Methods】 A total of 180 COPD patients in our hospital from September 2016 to July 2018 were enrolled in this study. The physical activities of patients were recorded and evaluated. The factors affecting physical activity were analyzed by Logisitic regression analysis. 【Results】 The score of the physical activity scale (PACE) in 180 COPD patients were (72.02±23.59) points. There were no significant differences in PACE scores among patients with different gender, age, marital status, payment method of medical expenses and place of residence (P>0.05). However, there were significant differences in physical activity levels of patients with different oxygen therapy status, modified dyspnea index (mMRC) score and GOLD lung function grading (P<0.05). Logisitic regression analysis showed that oxygen therapy status, mMRC score, GOLD pulmonary function classification, duration of illness, SES6 score, MFI-20 score, and SF-36 score were the influencing factors of physical activity in COPD patients. Person correlation analysis showed that the patient's physical activity level was negatively correlated with the patient's illness time and MFI-20 score (r=-0.284, P<0.01; r=-0.492, P<0.01); it was positively correlated with SES6 score and SF-36 score (r=0.675, P<0.01; r=0.443,P<0.01).【Conclusion】 Oxygen therapy status, mMRC score, GOLD grading, sick time, SES6 score, MFI-20 score and SF-36 score are the influencing factors of physical activity in COPD patients. Therefore, in the process of pulmonary rehabilitation treatment, it is necessary to maintain a good oxygen therapy condition, reduce the patient's illness time and fatigue, enhance physical activity, and improve self-efficacy and quality of life.
