TLDR
In the absence of a recent concussion, symptom reporting is related to sex and preexisting conditions and consideration of sex and pre-existing health conditions can help prevent misinterpretation of symptoms in student athletes who sustain a concussion.Abstract:
Importance Every state in the United States has passed legislation for sport-related concussion, making this health issue important for physicians and other health care professionals. Safely returning athletes to sport after concussion relies on accurately determining when their symptoms resolve. Objective To evaluate baseline concussion-like symptom reporting in uninjured adolescent student athletes. Design, Setting, and Participants In this cross-sectional, observational study, we studied 31 958 high school athletes from Maine with no concussion in the past 6 months who completed a preseason baseline testing program between 2009 and 2013. Results Symptom reporting was more common in girls than boys. Most students with preexisting conditions reported one or more symptoms (60%-82% of boys and 73%-97% of girls). Nineteen percent of boys and 28% of girls reported having a symptom burden resembling anInternational Classification of Diseases, 10th Revision(ICD-10) diagnosis of postconcussional syndrome (PCS). Students with preexisting conditions were even more likely to endorse a symptom burden that resembled PCS (21%-47% for boys and 33%-72% for girls). Prior treatment of a psychiatric condition was the strongest independent predictor for symptom reporting in boys, followed by a history of migraines. For girls, the strongest independent predictors were prior treatment of a psychiatric condition or substance abuse and attention-deficit/hyperactivity disorder. The weakest independent predictor of symptoms for both sexes was history of prior concussions. Conclusions and Relevance In the absence of a recent concussion, symptom reporting is related to sex and preexisting conditions. Consideration of sex and preexisting health conditions can help prevent misinterpretation of symptoms in student athletes who sustain a concussion.read more

TL;DR: I-RFA is a protective factor associated with less severe acute symptoms and shorter recovery after SRC, and conveying this message to athletes, coaches, and others involved in the care of athletes may promote timely injury reporting.
