Neighborhood disadvantage and the back-to-school epidemic of viral-associated asthma exacerbations.

Background: Rates of viral-associated asthma exacerbations typically increase when children return to school after the summer holiday. The effect of neighborhood disadvantage on this back-to-school increase in viral-associated asthma exacerbations is unknown.

Objective: We aimed to evaluate the effect of neighborhood disadvantage on the back-to-school increase in asthma-related emergency department (ED) visits.

Neighborhood-level variability in asthma-related emergency department visits in Central Texas.

Background: The extent to which incidence rates of asthma-related emergency department (ED) visits vary from neighborhood to neighborhood and predictors of neighborhood-level asthma ED visit burden are not well understood.

Objective: We aimed to describe the census tract-level spatial distribution of asthma-related ED visits in Central Texas and identify neighborhood-level characteristics that explain variability in neighborhood-level asthma ED visit rates.

Methods: Conditional autoregressive models were used to examine the spatial distribution of asthma-related ED visit incidence rates across census tracts in Travis County, Texas, and assess the contribution of census tract characteristics to their distribution.

The Role of Neighborhood Air Pollution in Disparate Racial and Ethnic Asthma Acute Care Use.

The share of Black or Latinx residents in a census tract remains associated with asthma-related emergency department (ED) visit rates after controlling for socioeconomic factors. The extent to which evident disparities relate to the within-city heterogeneity of long-term air pollution exposure remains unclear. To investigate the role of intraurban spatial variability of air pollution in asthma acute care use disparity.

Do upper respiratory viruses contribute to racial and ethnic disparities in emergency department visits for asthma?

Background: There are marked disparities in asthma-related emergency department (ED) visit rates among children by race and ethnicity. Following the implementation of coronavirus disease 2019 (COVID-19) prevention measures, asthma-related ED visits rates declined substantially. The decline has been attributed to the reduced circulation of upper respiratory viruses, a common trigger of asthma exacerbations in children.
