Patients were assessed by age, airflow obstruction (FEV1), previous hospitalization, dyspnea (MRC scale), muscle strength (maximal quadriceps isometric force), body composition (skeletal muscle mass (SMM%), by octopolar bioimpedance) and DLPA (step counts per day) by accelerometer (GT3X). Pearson's correlation was used between DPLA (step counts) and all variables. Multiple linear regression analysis was performed to identify the independent factors associated with DPLA.Results: DLPA was associated with muscle strength, age, dyspnea, hospitalization in last year and airflow obstruction (DLPA = 10424 + 95*quadriceps strength – 117*age – 37*MRC scale – 1044*hospitalization in last year + 23*airflow obstruction) (hospitalization 1=yes; 0=no); (p<0.001; R2adjusted=0.32).Conclusion: COPD patients with weaker quadriceps strength, older, having more dyspnea and previous hospitalization and worst airflow obstruction have impaired daily life physical activity. Assessing and improving these variables during the clinical management of COPD patients could help to maintain themselves physically active. ER -
