| description | Introduction
This study examined the association between smoking status and
death from COVID-19.
Methods
This study used nationwide cohort data collected from the Korean National
Health Insurance Service, linking to information on all individuals who tested
positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The
smoking status of subjects who participated twice in national health screenings
between 2015 and 2018 was measured. This study investigated death from
COVID-19 among those who tested positive from 1 January to 30 May 2020.
Results
This study included 4259 patients who tested positive for SARS-CoV-2
in Korea. After adjusting for all potential confounding factors, current smokers
(adjusted odds ratio, AOR=3.75; 95% CI: 1.23–11.36) and recent quitters
(AOR=3.74; 95% CI: 1.12–12.53) were associated with an increased risk of
death from COVID-19 compared to never smokers. Compared with current
smokers, long-term quitters (AOR=0.33; 95% CI: 0.11–0.95) and never smokers
(AOR=0.27; 95% CI: 0.09–0.81) were associated with a reduced risk of death
from COVID-19.
Conclusions
Smoking was associated with an increased risk of death among patients
with COVID-19. Given the lower possibility of death in long-term quitters with
COVID-19, continuous smoking cessation among smokers or recent quitters is
needed. |
