Exposure to air pollution may contribute to the wide disparities between and within countries in the health burden from COVID-19. Air pollution is an important risk factor for several non-communicable diseases that increase vulnerability to COVID-19. Understanding whether the role of air pollution in COVID-19 is different from its role in the wider suite of respiratory infections is essential for identifying public health priorities.
The objective of COVAIR-CAT is to test whether long or short-term exposure to air pollution increases the risk of COVID-19 hospital admissions or mortality and to identify vulnerable subgroups in the general population of Catalonia.
The project aims to test whether:
- 1) long-term exposure to air pollution is associated with COVID-19 hospital admission or mortality;
- 2) short-term exposure to air pollution is associated with COVID-19 hospital admission or mortality following COVID-19 diagnosis;
- 3) the influence of long- or short-term exposure to air pollution on COVID-19 outcomes differs according to individual-level socio-demographic factors, comorbidities, area-level socioeconomic factors, or other environmental exposures; and
- 4) the influence of long-term air pollution exposure on COVID-19 hospital admissions and mortality differs from that for respiratory infections not due to SARS-COV-2 infection.
We will use data linkage of electronic health records to construct a large, population-based cohort covering nearly the full population of Catalonia. By leveraging, individual-level data from primary care, laboratory testing, hospital admissions, and mortality registries, we will follow all adult individuals registered in the public health system of Catalonia, Spain in 2015 (n=5 million) through the end of 2020. Geocoded residential addresses will be linked to modeled particulate matter (PM10, PM10-2.5, PM2.5, PM2.5 absorbance), oxides of nitrogen, and ozone.
COVAIR-CAT will generate new, practical knowledge related to the intersection of two major public health challenges: air pollution and COVID-19.
