Relationship between child opportunity index and body mass index

Background: The Childhood Opportunity Index (COI) is a relatively new measure for assessing opportunity across education, health and environment, and socioeconomic context. Research indicates that higher COI is associated with lower obesity risk; however, existing research offers no evidence for differences, or lack thereof, across racial/ethnic groups. The larger body of research on the relationship between neighborhood environments and obesity risk among Hispanic children with low-income between 5 and 11-year-olds is limited. The study aims to further explore the relationship between neighborhood opportunities, measured by the COI, and children's body mass index Materials and methods: The data are from a sample of Hispanic child-parent dyads ( Results: After adjusting for covariates, children in the second ( Conclusions: All the higher COI levels were linked to healthier weight status compared to the lowest COI level, though the pattern was not linear for any of the observed associations. Further investigation into the impact of different COI levels may be warranted to assess each quartile's impact against each other, which was outside the scope of the current study. Results also provide evidence for potentially strengthening intervention supports for those at the lowest COI level, respective to those from all other COI levels.
