(Count any teams run by your school or community groups.)” Response options were “0 teams, 1 team, 2 teams, and 3 or more teams.” Prevalence estimates were computed overall and by sex (female or male), grade (9, 10, 11, or 12), the number of sports teams on which students played (0, 1, 2, or ≥3), and race/ethnicity (non-Hispanic white, non-Hispanic black, or Hispanic). In 2017, CDC included a question about concussions on the national YRBS questionnaire for the first time. In 2017, the school response rate was 75%, the student response rate was 81%, the overall response rate was 60%, † and the sample size was 14,765. ![]() An institutional review board at CDC approved the protocol for the national YRBS. ![]() In accordance with local parent permission procedures, students voluntarily completed an anonymous, self-administered questionnaire during one class period and recorded their responses on a computer-scannable answer sheet. YRBS is a biennial, cross-sectional, school-based survey that uses a three-stage cluster sampling design to produce nationally representative samples of public and private school students in grades 9–12 ( 3). These findings underscore the need to 1) foster a culture of safety in which concussion prevention and management is explicitly addressed 2) expand efforts to educate students, parents, coaches, and health care providers regarding the risk for concussion and 3) identify programs, policies, and practices that prevent concussions. Among all sex, grade, and racial/ethnic subgroups, the odds of reporting a concussion increased significantly with the number of sports teams on which students played. Concussion prevalence was significantly higher among male students than among female students and among students who played on a sports team than among students who did not. Overall, 15.1% of students (approximately 2.5 million*) reported having at least one of these concussions during the 12 months before the survey, and 6.0% reported two or more concussions. high school students related to playing a sport or being physically active, CDC analyzed data from the 2017 national Youth Risk Behavior Survey (YRBS). To estimate the prevalence of concussions among U.S. ![]() Estimates assessed from emergency departments miss concussions treated outside hospitals, those generated using high school athletic trainer reports miss concussions sustained outside of school-based sports ( 2), and both sources miss medically untreated concussions. Surveillance methods used to monitor concussions among youths likely underestimate the prevalence. Short-term and long-term sequelae of concussions can include cognitive, affective, and behavioral changes ( 1). ![]() Increased susceptibility to concussions and longer recovery times among high school athletes compared with older athletes ( 1) make concussions among youths playing a sport or being physically active an area of concern. ![]()
