Traffic Congestion and Asthma-related Hospital Visits in Central TX

As one of the most common health diseases that are susceptible to environmental changes in urban neighborhoods, asthma is a major health concern among the disadvantaged populations living in urban neighborhoods with a higher proportion of poverty and racial/ethnic minorities (Corburn et al. 2006). The Centers for Disease Control and Prevention (CDC) estimated that 5.1 million U.S. children had asthma in 2019. Notably, air pollution has been a growing concern in environmental health, being considered to trigger new asthma symptoms and exacerbate existing asthma symptoms, and plenty of studies provide evidence for the association between air pollution and respiratory diseases (English et al. 1999; Janssen et al. 2003; McConnell et al. 2006; McCreanor et al. 2007; Guarnieri and Balmes 2014). Traffic congestion increases vehicle emissions and degrades ambient air quality (Zhang and Batterman 2013). However, the understanding of the association between traffic congestion and asthma is very limited. Thus, the research question is whether traffic congestion is a determinant of asthma-related hospital visits.
