Marginalization and health: children's asthma on the Texas‐Mexico border

Abstract

PurposeThe purpose of this paper is to investigate children's vulnerability to asthma and its relationship with marginalized locations. More specifically, the effects of zip code level social predictors on children's asthma and their conditionality on location in the Texas‐Mexico border region are explored. The border region is perhaps the most marginalized in the USA.Design/methodology/approachData for analysis comes from the State of Texas and the US Bureau of the Census. Negative binomial regression models are used to predict asthma hospitalizations using a set of social predictors. Then, interaction effects are used to test if social predictors are conditional on border location.FindingsWithin the state of Texas, location in a metropolitan area, location along the US‐Mexico border, percent Hispanic, percent African American and percent Native American are positive and significant predictors of asthma hospitalizations; social class is negative and significant. The effects of proportion of Hispanics who were foreign born, median year of home construction, and percent of homes with inadequate heating are conditional on a zip code's location relative to the US‐Mexico border, with the slopes being steeper in border locations. Findings in general suggest that locational and social factors intersect in marginalized places (i.e. border regions of Texas) to create vulnerability to asthma hospitalizations.Research limitations/implicationsThis study is conducted solely in the USA.Originality/valueAs sociologists continue to consider space as a factor in health inequalities, this paper demonstrates the utility of considering space as operating at more than one scale.
