NCHS Data Brief. 2021 Dec(423):1-8.
A concussion is a mild type of traumatic brain injury (1). Previous studies using national data have shown that concussion prevalence can differ by survey methodology and question wording (2). The 2020 National Health Interview Survey (NHIS) included questions on concussion to measure both symptoms and diagnosis from a health care provider to provide a more complete understanding of the public health burden, because children with mild injuries may not see a doctor or receive a diagnosis. This report presents national estimates of lifetime symptomatology and health care professional diagnoses of concussions or brain injuries as reported by a knowledgeable adult, usually a parent, in children aged 0-17 years using data from the 2020 NHIS.
脑震荡是一种轻度的创伤性脑损伤 (1)。先前使用国家数据的研究表明，脑震荡的患病率可能因调查方法和问题措辞而有所不同 (2)。2020 年全国健康访谈调查 (NHIS) 包含有关脑震荡的问题，以从医疗保健提供者那里衡量症状和诊断，从而更全面地了解公共卫生负担，因为轻度受伤的儿童可能不会看医生或接受诊断。本报告使用 2020 年 NHIS 的数据，根据知情成年人（通常是父母）报告，提供了 0-17 岁儿童一生中出现脑震荡或脑损伤症状和接受医疗专业人员诊断的全国估计数。
