ABSTRACT
Background:
Few studies have shown that smokers are more likely than nonsmokers to contract COVID-19, while some reports indicate that smokers are underrepresented among those requiring hospital treatment for this illness.
Objective:
This study was designed and implemented to investigate the severity and outcomes of COVID-19, based on underlying smoking status.
Methods:
This was a cross-sectional study that was implemented in Tehran and Ahvaz, with all COVID-19 hospitalized patients, from February to June 2021. A total of 18200 patients with a positive PCR test were observed. A check list of demographic data and smoking history was completed and analyzed.
Results:
In all, 11112 (61.1%) patients were male and the mean age was 47.9±11.3 years; 1508 smokers (8.3%) were seen with any type of tobacco consumption. The frequency of ICU admission in the smokers was significantly higher than non-smokers (23.9% vs 18.8%). Use of more than 3 medications in the smokers was significantly higher (70.6% vs 52%). A comparison between patients based on smoking indicates that the death rate was significantly higher in smokers (31.6% vs 25.6%).
Conclusions:
Smokers with COVID-19 had more severe and worse outcomes.
