The aim of this study was to evaluate the effectiveness of mask use by asking individuals who did not routinely wear masks to wear them. However, after the baseline survey had been completed and before the mask-wearing intervention was initiated, the COVID-19 pandemic occurred. As mask-wearing became widespread in the study area, local lifestyle practices were no longer comparable to those before the COVID-19 pandemic. Therefore, we decided not to proceed with the intervention (i.e., mask use for the prevention of exposure to ambient and indoor air pollution). The study is now being analyzed using the baseline data only, focusing on comparisons between the dry and rainy seasons.
