Untangling risk factors including discipline-specific exposure for injuries in preprofessional and professional circus artists in the USA

Abstract

ObjectiveThis prospective cohort study quantified injury patterns related to specific circus discipline exposure in preprofessional and professional circus artists.MethodsCircus artists (n=201; ages 13–69; 172 female, 29 male assigned sex at birth) were enrolled in 10 cities across the USA. Participants were followed for 1 year from enrolment, completing a weekly training log and undergoing a physical therapist evaluation for injuries. The circus-specific extension of the International Olympic Committee 2020 consensus on recording injury and illness in sports was used to analyse injury patterns.ResultsThe study completion rate was 77% (n=155). Data were analysed by participant subgroup (age, professional status, sex at birth). The highest injury rates in participant subgroups were for males (5.69/1000 exposures) and related to discipline subgroups, were in aerial with ground elements (5.93/1000 exposures) and aerial (4.26/1000 exposures). Adults had more injuries related to aerial, whereas adolescents had more related to ground disciplines (χ2(2)=10.62, p=0.005) and non-time loss injuries (χ2(1)=5.45, p=0.02). Females had a higher proportion of repetitive injuries (70% vs 55%) than males (χ2(1) = 4.43, p=0.035). Individuals with an eating disorder history had more (p<0.004) injuries (mean 2.27±2.29) than those without (mean=1.48±0.96).ConclusionsThis study showed that intrinsic factors (age, sex at birth and history of eating disorder) and extrinsic factors (circus discipline exposure) affect injury risk. We need to account for the intersectionality of these factors to address risk management at an individual and group level.
