Researchers recently published an article titled "The Child Opportunity Index and Disparities in Pediatric Asthma Hospitalizations Across One Ohio Metropolitan Area, 2011-2013" in The Journal of Pediatrics which used data from the Child Opportunity Index to examine the relationship between neighborhood quality and childhood asthma severity. The article collected data from a county in southwest Ohio. It compared asthma hospitalization rates by area, then used the COI to determine whether there were differences between them based on opportunity levels. The researchers found that hospitalization rates were seven to nine times higher in low or very low opportunity neighborhoods.
