RESUMO
CONTEXT: Pediatric mild traumatic brain injuries (mTBIs) represent an evolving field of interest in youth athletics. Although most players recover within 4 weeks, some have symptoms that last longer. Little is known about youth health-related quality of life (HRQoL) after mTBI. OBJECTIVES: To characterize youth HRQoL after soccer-related mTBI and to identify predictors of individual differences in HRQoL recovery. DESIGN: Prospective cohort study. SETTING: Youth soccer. PARTICIPANTS: Soccer players, aged 8 to 17 years, who sustained an mTBI (n = 23) or orthopaedic injury (OI, n = 24) or remained uninjured (n = 23) during a single season. MAIN OUTCOME MEASURE(S): We assessed HRQoL via the Pediatric Quality of Life Inventory, version 4.0, and postconcussive symptoms via the Health and Behavior Index. Serial assessments occurred at 24 to 48 hours, 7 days, 30 days, and 90 days postinjury via telephone interview. RESULTS: At 7 days postinjury, the mTBI and OI groups had poorer total HRQoL (F2,67 = 11.35, P < .001) than the uninjured control group. At 7 days, the mTBI group had the poorest psychosocial HRQoL, whereas the OI group had the poorest physical HRQoL. Differences between the mTBI and uninjured control groups resolved by 30 days. Within the mTBI group, players with significant postconcussive symptoms at 7 days had poorer total (F1,21 = 23.071, P ≤ .001; F1,21 = 5.798, P = .028), psychosocial (F1,21 = 16.488, P = < .001; F1,21 = 5.050, P = .039), and physical (F1,21 = 21.671, P = < .001; F1,21 = 5.119, P = .038) HRQoL at 7 and 30 days, respectively, than players with minimal symptoms; these differences resolved by 90 days. CONCLUSIONS: As a group, youth soccer players who sustained mTBI had transient impairments in HRQoL that resolved by 30 days. A subset of players with significant postconcussive symptoms at 7 days postinjury had poorer HRQoL for at least 30 days postinjury than those whose postconcussive symptoms had resolved within a week of injury. This suggests ongoing recovery in this subset at 30 days and the potential utility of HRQoL as a measure of recovery.
