The purpose of this study was to assess the prevalence of head and neck injury (HNI) requiring hospitalization or emergency care and traumatic brain injury with loss of consciousness (TBI-LOC) among youth athletes and nonathletes (ages 9–10 years) using the baseline cohort of the Adolescent Brain Cognitive Development study.

National data from the baseline cohort of the Adolescent Brain Cognitive Development study (2016–2018; n = 11,869) were analyzed.

The analysis found that 12.1% of the sample indicated HNI during their lifetime, while .8% indicated TBI-LOC. Participation in multiple sports (adjusted prevalence rate ratio [aPRR] = 1.29, 95% confidence interval [CI] = 1.06,1.55), contact sports (aPRR = 1.19, 95% CI = 1.05,1.34), and who had participated in sport for five or more years (aPRR = 1.42, 95% CI =1.16,1.73) had modestly higher prevalence rate ratios of reporting HNI …
