Is Household Composition Associated With Repeat Fight Injuries in Adolescents Living in Urban Neighborhoods

The association of household composition with violence-related injury risk has not been explored in the at-risk urban adolescent population. We hypothesize that, similar to the unintentional risk association, higher adult:child ratio, lower household size, and the presence of a grandparent are protective and thus associated with lower risk for repeat fight injury in this population. This is a cross-sectional study of 10- to 15-year-old adolescents who were evaluated in two urban, pediatric emergency departments (EDs; Baltimore, MD, Philadelphia, PA) for a peer fight-related injury between June 2014 and June 2016. Logistic regression was used to test for associations between each household composition measure of interest and youth self-report of a medically attended fight-related injury within the prior 12 months. Of 187 eligible youth, 62 (33%) reported at least one such repeat fight-related injury. With control for potential confounders, youth with past fight injuries did not differ in adult:child ratio ...
