Association Between Social Determinants of Health and Concussion Among High School Students in the United States.

We examined the association between social determinants of health and the likelihood of sustaining a concussion among adolescents. Participants in this cross-sectional study were 7164 high school students who completed the 2021 Adolescent Behaviors and Experiences Survey (52.7% girls; mean age = 16.0 years, SD = 1.2; age range 12-18 years). Logistic regression was used to determine which social determinants of health variables were associated with a self-reported history of concussion from playing a sport or being physically active over the past year. One in 10 adolescents (n = 716; 10.0% total; 11.8% of boys, 8.3% of girls) reported sustaining a concussion during the past year. Seven of 10 adolescents (70.3%) reported experiencing at least 1 of 8 negative social determinants of health. A multivariable logistic regression was statistically significant (P < .001), indicating that the negative social determinants of health were associated with having sustained a concussion during the past year; the model explained 12.5% (Nagelkerke R²) of the variance in concussion. Controlling for all other predictors, sports participation (odds ratio [OR] = 3.72, medium effect), housing instability (OR = 3.25, small-medium effect) and limited English language proficiency (OR = 3.05, small-medium effect) were the strongest independent predictors of sustaining concussion within the past year. Adolescents who lived in a neighborhood where there is violence (OR = 1.78, small effect), who were bullied (OR = 1.57, very small effect), and who experienced food insecurity (OR = 1.36, very small effect) were more likely to have sustained a concussion. Research is needed to understand the nature of these determinant-injury associations. Whether social determinants of health are associated with specific treatment and rehabilitation needs, and time to recover following concussion, should be examined with prospective studies.
