Summary
Former smokers with COVID-19 (coronavirus disease 2019) face higher risks of intensive care unit admission. This study highlights ex-smokers as a vulnerable group needing special attention during the pandemic.
Area of Science:
- Infectious Diseases
- Public Health
- Epidemiology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused widespread infections globally.
- Iran has experienced a high prevalence of COVID-19, necessitating research into risk factors.
- Understanding the impact of smoking on COVID-19 outcomes is crucial for public health strategies.
Purpose of the Study:
- To investigate the association between smoking status and COVID-19 outcomes.
- To analyze sociodemographic characteristics in relation to COVID-19.
- To identify vulnerable patient groups during the pandemic.
Main Methods:
- A cross-sectional survey was conducted among hospitalized COVID-19 patients.
- Data collected included basic and clinical characteristics, and smoking status.
- Outcomes, specifically intensive care unit (ICU) admission, were recorded.
Main Results:
- Out of 206 participants with complete data, 16.50% were current smokers and 6.79% were ex-smokers.
- A significant relationship was found between ex-smoking status and ICU admission in COVID-19 patients.
- Men constituted 66.5% of the study population.
Conclusions:
- Ex-smokers hospitalized with COVID-19 represent a vulnerable population.
- This group exhibits a significantly higher morbidity rate.
- Special attention and tailored interventions are warranted for ex-smoker COVID-19 patients.

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...

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...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
