Cross-sectional survey examines concussion diagnosis prevalence in US children and adolescentsHow many U.S. kids have been diagnosed with a concussion or brain injury?

This cross-sectional survey analyzed data from the United States National Health Interview Survey to determine what percentage of children and adolescents aged ≤17 years had ever received a diagnosis of concussion or brain injury. The study did not report any intervention, exposure, or comparator group, focusing solely on descriptive prevalence assessment.

The primary outcome was the percentage who had ever received such a diagnosis. However, the study did not report the actual prevalence result, effect size, absolute numbers, p-values, confidence intervals, or direction of findings. No secondary outcomes were specified. Follow-up duration was not reported.

Safety and tolerability data were not reported. The study limitations were not specified in the provided information. Funding sources and conflicts of interest were not reported. The analysis represents a descriptive snapshot without causal implications or comparative effectiveness data.

Practice relevance was not reported. This survey provides only basic descriptive information about diagnostic prevalence without details on methodology, results, or clinical context. Clinicians should interpret these findings cautiously given the lack of reported results and methodological details.
