Social determinants of health and somatic growth in preterm infants and children with chronic lung disease.

Of the three measures analyzed, national COI (nCOI) showed a significant association with mean weight z-scores, mean ADI showed some association with mean weight z-scores, and the percentage of a community experiencing food insecurity showed no association with mean weight z-scores. After adjusting for gestational age, BPD severity, and presence of a GT, children living in areas of greater opportunity (higher nCOI values), had significantly lower weight z-scores at 12 months corrected and at 24 and 36 months uncorrected CONCLUSIONS: Our findings suggest that the COI 2.0, a multidimensional measure, captures more facets of an individual's social environment, as compared to the singular nature of a measure of food insecurity. There are several potential explanations for the phenomenon seen, and further understanding of this dynamic is crucial for designing effective interventions and policies to better address inequities in outcomes.
