Abstract
OBJECTIVE: While prior studies have found parental socioeconomic status (SES) affects the outcomes of pediatric traumatic brain injury (TBI), the longitudinal trajectory of this effect is not well understood. METHODS: This prospective cohort study included children 8-18 years of age admitted to six sites with a complicated mild (n = 123) or moderate-severe TBI (n = 47). We used caregiver education and household poverty level as predictors, and multiple quality of life and health behavior domains as outcomes. Differences at 6, 12, and 24 months from baseline ratings of pre-injury functioning were compared by SES. We examined the association between measures of SES and domains of functioning over the 24 months post-injury in children with a complicated mild or moderate- severe TBI, and determined how this association varied over time. RESULTS: Parental education was associated with recovery among children with complicated mild TBI; outcomes at 6, 12, and 24 months were substantially poorer than at baseline for children with the least educated parents. After moderate-severe TBI, children in households with lower incomes had poorer outcomes compared to baseline across time. IMPLICATIONS: Parental education and household income were associated with recovery trajectories for children with TBI of varying severity.
