Ambient Air Pollution and Asthma-Related Outcomes in Children of Color of the USA: a Scoping Review of Literature Published Between 2013 and 2017
Purpose of Review
Given racial disparities in ambient air pollution (AAP) exposure and asthma risk, this review offers an overview of the literature investigating the ambient air pollution-asthma relationship in children of color between 2013 and 2017.
AAP is likely a key contributor to the excess burden of asthma in children of color due to pervasive exposure before birth, at home, and in school. Recent findings suggest that psychosocial stressors may modify the relationship between AAP and asthma.
The effect of AAP on asthma in children of color is likely modulated by multiple unique psychosocial stressors and gene-environment interactions. Although children of color are being included in asthma studies, more research is still needed on impacts of specific criteria pollutants throughout the life course. Additionally, future studies should consider historical factors when analyzing current exposure profiles.

Asthma prevalence was more than twice as high in non-Hispanic black children (15.7%) and nearly twice as high in Puerto Rican children (12.9%) than rates in non-Hispanic white children (7.1%). Additionally, the analysis found that children of low-income families were more likely (10.5%) to have asthma than those in higher income families (~7%).

Identified asthma risk factor distribution at the neighborhood level in Houston, and found that low-income and middle-income neighborhoods are disproportionately exposed to air pollutants. Although within-race asthma risk decreased as neighborhood quality increased, African American children still had higher rates of asthma than white children from the same neighborhoods, suggesting that even at the high end of the socioeconomic status spectrum, the asthma disparity persists.
