Living in environmental justice areas worsens asthma severity and control: Differential interactions with disease duration, age at onset, and pollution.

ABSTRACT:

Background

Impoverished and historically marginalized communities often reside in areas with increased air pollution.

Objective

We evaluated the association between environmental justice (EJ) track and asthma severity and control as modified by traffic-related air pollution (TRAP).

Methods

We performed a retrospective study of 1526 adult asthma patients in Allegheny County, Pa, enrolled in an asthma registry during 2007-20. Asthma severity and control were determined using global guidelines. EJ tract designation was based on residency in census tracts with ≥30% non-White and/or ≥20% impoverished populations. TRAP exposures (NO₂ and black carbon) for each census tract were normalized into pollution quartiles. Generalized linear model analyses determined the
