Prevalence, attitude, knowledge, and risk perception towards COVID-19 in COPD patients associated to biomass exposure

Abstract

Chronic obstructive pulmonary disease (COPD) patients due to biomass exposure (BE-COPD) could be more affected than COPD due to tobacco smoke (TE-COPD) by the coronavirus disease 2019 (COVID-19) pandemic. The aim of this work was to determine the prevalence of COVID-19 in BE-COPD and TE-COPD and if housing conditions, poor attitude, knowledge, and risk perception towards COVID-19, particularly in BE-COPD women, could represent a risk factor for contagion.An 11% prevalence of COVID-19 was found with no significant difference between COPD groups. The BE-COPD group showed poorer socioeconomic status. No significant differences were found to be associated with SARS-CoV-2 infection regarding housing conditions, poor knowledge, attitude, and risk perception towards COVID-19. Living in urban areas and perceiving risk in COVID-19 were significantly associated with increased adherence to sanitary measures and concern of contagion. Around 40% of all patients showed poor risk perception and adherence to sanitary measures towards COVID-19.
