872 - Relative risk factors for Low Physical activity in COPD

Chronic obstructive pulmonary disease (COPD) is characterized by progressive and largely irreversible airflow limitation. The GOLD guidelines recommend regular PA for all patients with COPD. This study aimed to analyze factors that affect low PA in individuals with COPD.

Design:

Korean National Health and Nutrition Examination Survey data from 2014 to 2019 were used in this study. The study population included adults aged 40 to 79 years with COPD, defined as FEV1/FVC< 0.7. PA was assessed using the Korean version of the Global Physical Activity Questionnaire (GPAQ) and classified into high, moderate, and low PA levels based on the WHO guideline. The statistical analysis reflected the complex sampling design of the KNHANES. 

Results:

2,336 participants were finally included. Classified by the PA level, there were 190 (8.13%) with high PA, 880 (37.67%) with moderate PA, and 1,266 (54.20%) with low PA. The mean age was 65.13±9.16 years. In univariable analysis, low activities in COPD showed a correlation with age (OR 1.013), male (OR 0.792), abdominal obesity (OR 1.181), urban living (OR 0.654), high education level (OR 0.599), high income (OR 0.759), living alone (OR 1.461), Ex-smoker (OR 0.832), FVC (OR 0.993), high grip strength (OR 0.974), EQ-5D index (OR 0.157), hypertension (OR 1.186), diabetes (OR 1.215), chronic kidney disease (CKD)(OR 1.624), and arthritis (OR 1.301). In multivariable analysis, variables associated with low activities were urban living (OR 0.626), high education level (OR 0.693), current smoking (OR 1.524), FVC (OR 0.994), high grip strength (OR 0.975), EQ-5D index (OR 0.328), and CKD (OR 1.421).

Conclusions:

This study identified several factors associated with low physical activity. These findings can be used to develop strategies to improve PA levels in individuals with COPD and ultimately improve their quality of life.
