Health-Related Quality of Life, Depression, and Smoking Status in Patients with COPD: Results from the Behavioral Risk Factor Surveillance System Data

Abstract

Background: Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of mortality. People living with COPD often have a common triad of problems including decreased health-related quality of life (HRQL), smoking, and depression. Identifying barriers to preventing and treating COPD is of the utmost importance. The purpose of this study is to examine the relationship between HRQL, depression, and smoking status for patients with COPD. Methods: The 2016 BRFSS data was used to perform a cross sectional analysis of adult patients with a diagnosis of COPD. A comprehensive descriptive analysis of all study variables for those participants having COPD was performed. Then relationships between general HRQL, depression, and smoking status were examined. Data were analyzed using SPSS. Results: The original 2016 BRFSS dataset contained responses from 486,303 participants. After selecting participants who self-identified as having a diagnosis of COPD, 40,682 individual participants remained in the dataset for further analysis. The participants with COPD were mostly female, over the age of 65, with low-incomes, attended a year of college or less, with some type of healthcare coverage. Patients with a dual diagnosis of COPD and depression have poorer HRQL and an increased number of cigarettes smoked compared to those patients with COPD. Likewise, there is a significant relationship between HRQL and smoking status for patients with a dual diagnosis of COPD and depression. Conclusion: Depression as a comorbidity does have a statistically significant relationship with patients HRQL and smoking status. Future research should be aimed at increasing screening and treatment for depression in patients with COPD who continue to smoke. Further research on the cyclical relationship between COPD, depression, and smoking cessation would be beneficial.
