Smoking is Associated with COVID-19 Progression: A Meta-Analysis
Medrxiv : the Preprint Server for Health Sciences
|June 9, 2020
Summary
Smoking significantly increases the risk of COVID-19 progression. Smokers with coronavirus disease 2019 (COVID-19) had double the odds of severe disease compared to non-smokers.
Area of Science:
- Public Health
- Epidemiology
- Internal Medicine
Background:
- The impact of smoking on COVID-19 progression remains a critical public health concern.
- Understanding risk factors for severe coronavirus disease 2019 (COVID-19) is essential for pandemic management.
Approach:
- A systematic meta-analysis of 12 published studies was conducted to evaluate the association between smoking and COVID-19 progression.
- Data were extracted from studies reporting smoking status and disease outcomes in COVID-19 patients, with a random effects model applied for analysis.
Key Points:
- The meta-analysis included 9,025 COVID-19 patients, with 5.5% reporting a history of smoking.
- Smokers demonstrated a significantly higher odds ratio (OR 2.25) for COVID-19 progression compared to never smokers (p=0.001).
- Limitations suggest the actual risk associated with smoking may be underestimated.
Conclusions:
- Smoking is identified as a significant risk factor for the progression of COVID-19.
- Healthcare providers should incorporate smoking status assessment into patient management and promote smoking cessation interventions.

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

3.4K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.
