• Description:
  Objectives:
  
  To examine level of play (LOP) as a risk factor for concussion severity and recovery-related outcomes among high school athletes, stratified by sex, and among boys, by sport (football, non-football male sports).
  
  Design/Setting:
  
  Secondary analysis of data collected through the High School Reporting Information Online surveillance system for academic years 2007–2008 through 2018–2019.
  
  Participants:
  
  A total of 9916 concussions were reported between the academic years 2007–2008 and 2018–2019 from 9 sports (5189 from football; 2096 from non-football male sports; 2631 from female sports).
  
  Main Outcome Measure:
  
  Examined the association between LOP (Freshman, Junior Varsity JV, and Varsity teams) and concussion outcomes (number of concussion symptoms, symptom resolution time SRT, and time to return to play RTP).
  
  Results:
  
  Compared with Varsity football athletes, concussed JV football athletes had on average 0.19 fewer concussion symptoms, longer SRT (>1 week vs <1 week: odds ratio OR = 1.3; 95% confidence interval CI, 1.1–1.5), and longer RTP (1–3 weeks vs <1 week: OR = 1.5; 95% CI, 1.2–1.9; >3 weeks vs <1 week: OR = 1.6; 95% CI, 1.1–2.3). Compared with Varsity football athletes, Freshman football athletes had on average 0.48 fewer concussion symptoms, longer SRT (OR = 1.3; 95% CI, 1.1–1.5), and longer RTP (1–3 weeks vs <1 week: OR = 1.5; 95% CI, 1.1–2.0; >3 weeks vs <1 week: OR = 2.0; 95% CI, 1.3–3.0). Similarly, compared with female athletes on Varsity teams, concussed JV female athletes had longer RTP (1–3 weeks vs <1 week: OR = 1.8; 95% CI, 1.2–2.7). Trend analyses revealed an increase in the number of concussion symptoms between 2015–2016 and 2018–2019, a decrease between 2009–2010 and 2018–2019 for SRT of less than 1 week, and an increase between 2014–2015 and 2018–2019 for RTP of less than 1 week among Varsity football athletes. Among Varsity female athletes, there was a linear decrease during the study period for RTP of less than 1 week.
  
  Conclusions:
  
  Despite a higher number of symptoms overall and in recent years, Varsity football players had shorter RTP than Freshman and JV athletes.
