The non-Hispanic black-white discrepancy has plateaued in recent years, and this is mostly because the prevalence of asthma among non-Hispanic black children has stopped rising.
From 2001 to 2009, there was an overall rise in the prevalence of childhood asthma; this was followed by a plateau and a drop in 2013. From 2001 to 2013, multivariate logistic regression revealed no change in prevalence among non-Hispanic white, Puerto Rican, and children living in the Northeast and West; increasing prevalence among children aged 10 to 17 who are poor and reside in the South; increasing then plateauing prevalence among non-Hispanic black children aged 5 to 9, and increasing then decreasing prevalence among Mexican children aged 0 to 4 years. Black-white gaps between non-Hispanic races ceased widening, while Puerto Rican children continued to have the highest incidence.
