Smoking significantly impacts respiratory quality of life in Lebanon. Both smokers and non-smokers experience reduced quality of life, with environmental factors and smoking habits worsening outcomes in Chronic Obstructive Pulmonary Disease (COPD) patients.
Area of Science:
- Pulmonary Medicine
- Public Health
- Quality of Life Research
Background:
- Chronic Obstructive Pulmonary Disease (COPD) poses a growing global health challenge.
- Understanding COPD's impact on quality of life is crucial for patient care.
- The Clinical COPD Questionnaire (CCQ) is a key tool for assessing respiratory health.
Purpose of the Study:
- To evaluate the CCQ's validity and reliability in the Lebanese population.
- To assess respiratory quality of life among Lebanese adults, comparing smokers and non-smokers.
- To identify predictors of reduced quality of life in individuals with COPD.
Main Methods:
- Cross-sectional national study utilizing CCQ data.
- Assessed construct validity, reliability, and correlations with FEV1/FVC.
- Employed multiple regression analysis to determine quality of life predictors.
Main Results:
- The CCQ exhibited excellent psychometric properties and consistency.
- Smokers reported lower respiratory quality of life than non-smokers, irrespective of COPD status.
- Environmental factors, lower education, and smoking (cigarette and waterpipe) independently predicted lower quality of life in COPD patients.
Conclusions:
- Smoking detrimentally affects respiratory quality of life in Lebanese adults.
- Findings underscore the need to emphasize smoking cessation and patient education.
- Addressing environmental and lifestyle factors is vital for improving COPD patient outcomes.
