Do male and female adolescents report symptoms differently after concussion?

Abstract

ABSTRACT We investigated sex-based differences in the presence and severity of aggregated symptom indicators as well as individual concussion symptoms. Materials and Methods: A cross-sectional examination of sex differences in symptoms reported by adolescents upon initial concussion evaluation at a concussion clinic. Nine hundred and eighty-six adolescents completed the Sport Concussion Assessment Tool (SCAT5) symptom checklist. Chi-square and Mann-Whitney U tests were used for differences in the presence and severity of symptoms, respectively. Sex differences in global indices of symptom distress were compared. Results: Females endorsed more symptoms (Female: Median (M)=15, Interquartile range (IQR):9–18 vs. Male: M=11, IQR: 6–15, p<0.001) and a greater total symptom score (Female: M=37, IQR:16–45 vs. Male: M=20, IQR:8–39). After False Discovery Rate (FDR) adjustment, females endorsed the presence of 21 of 22 individual symptoms more frequently than males (p≤ 0.039), with greater symptom severity for 20 of 22 individual symptoms (p≤0.036). Moderate ESs were observed for sex-based differences in the total symptom score and the global severity index. Small ESs was observed for differences in most individual symptoms. Conclusions: The greater frequency and severity of concussion symptoms reported by female adolescents highlights the importance of considering sex as a modifier for the management of concussion.
