BACKGROUND: Child physical abuse is a significant cause of pediatric injury and death. Previous studies have described disparities in outcomes for physically abused children according to insurance status. We hypothesized that children treated for physical abuse would be more likely to live in neighborhoods with increased socioeconomic deprivation.
METHODS: We performed a retrospective review of children who were admitted with suspected physical abuse from 2011 to 2021. Home addresses at the time of admission were used to assign an Area Deprivation Index (ADI) of the neighborhood. Clinicopathologic and outcome variables were compared between children from neighborhoods in the top 10th and bottom 90th national neighborhood ADI percentile. Univariate and multivariate logistic models were constructed.
RESULTS: 184 children were included for analysis. Children from the top 10th (more impoverished) ADI percentile presented with more severe injuries, had higher area injury scores in the abdomen and extremities, and required admission to the intensive care unit more often, compared to children from the bottom 90th ADI percentile (all p-values <0.05). Children from high ADI neighborhoods were more likely to be discharged to a different caretaker compared to children from low ADI neighborhoods (71% caretaker change vs. 49% caretaker change, p=0.005). Univariate and multivariate logistic regression demonstrated statistically significant association between the ADI score and the need for caretaker change at the time of discharge (p=0.004).
CONCLUSIONS: Community-level social determinants of health are closely associated with child physical abuse. Child abuse reduction strategies might consider increased support for families with fewer resources and social support systems.
