A new study published in the journal Annals of Epidemiology used a novel modeling method to link electronic health records containing data on in-home environmental exposures to housing and neighborhood location data for children with asthma living in low-income households. It found that children living in homes with greater chances of having cockroaches and rodents had worse lung function. As the majority of the children in the study were Black and lived in historically segregated neighborhoods, these findings highlight the consequences of longstanding racial inequities in housing characteristics and quality, borne by structural racism.
