Background and objective The COVID-19 pandemic is one of the most important global crises in recent decades. The present study aims to investigate the effect of air pollution on the hospitalization and death rates due to COVID-19 in Tehran, Iran.
Method This is a descriptive-correctional study on data of hospitalized, recovered, and death rates due to COVID-19 in 141 hospitals and medical centers in Tehran from February 2020 to May 2022 obtained from the Ministry of Health and Medical Education. The data from 36 air pollution monitoring stations in Tehran (affiliated to Tehran Air Quality Control Company and the Environmental Protection Organization) were also collected. The pollutants in these stations based on the air pollution index (AQI) included PM10, PM2.5, carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3). Linear regression analysis, Pearson correlation test, and one-way analysis of variance were used to test the research hypotheses in SPSS software, version 26.
Results The effects of pollutants and the AQI on the hospitalization rate due to COVID-19 were significant. The pollutants O3 (β=0.765, t=2.049), CO (β=2.371, t=6.155), and PM2.5 (β=3.984, t=3.747) had a positive effect on the hospitalization rate, while the pollutants NO2 (β=-0.664, t=-2.198), PM10 (β=-0.813, t=-3.137), and the AQI (β=-2.806, t=-3.524) had a negative effect on the hospitalization rate. The effects of pollutants and the AQI on the death rate due to COVID-19 were also significant. The pollutants O3 (β= 0.840, t=2.203), CO (β=2.461, t=6.256), and PM2.5 (β=4.196, t=3.865) had a positive effect on the death rate due to COVID-19, while the pollutants NO2 (β= -0.736, t=-2.387), PM10 (β=-1.102, t=-4.166), SO2 (β= -0.312, t=-1.183), and the AQI (β= -2.658, t=-3.270) had a negative impact on the death rate. There was a strong and significant correlation between air pollution and death due to COVID-19 (r=0.849, P<0.001).
Conclusion By controlling the concentration of air pollutants, it is possible to reduce the rates of hospitalization and death caused by COVID-19.
