The mediation effect of indoor air quality on health: A comparison of homeowners and renters

This research aims to explore whether there is a health disparity between homeowners and renters affected by the indoor air quality of their dwellings. By proxying the presence of mold and smoke as conjoint facilitators of poor indoor air quality, we design a mediation model that previously has not been explored empirically. The structural path model in this study shows that there is indeed a disparity in health between homeowners and renters by demography, socioeconomic status, and dwelling condition. Our study argues that renters whose living conditions are generally worse off than homeowners are also unequal in their health status due to exacerbating effects from poor indoor air quality, which is endogenous to the state of the renter. The originality of this study is that it is the first study that empirically tests the mediation effect of poor indoor air quality of homeowners and renters using a structural equation path model.
