French HP, Deasy M, Gallagher R, et al. - Researchers investigated the prevalence of hip or groin pain in adolescent populations, via this systematic review. Eligible investigations that incorporated men and women 13 to 19 years of age were identified from five electronic databases explored until January 2019. Inclusion criteria were applied and overall 8 population‐based, 8 clinical, and 4 sports populations were examined. Studies were performed in Europe, North America, and Australia. The prevalence was divided into “0 to 3 months” and “3 months and above.” Based on 10 studies and 7 population studies, the overall prevalence of hip or groin pain in all adolescents from 0 to 3 months was identified to be 12% and 7%, respectively. From 0 to 3 months, pain prevalence of 13% was reported in cerebral palsy, based on 4 studies. Individual prevalence estimates were documented to be 6% and 31% in obese and 4% in hypermobility groups, respectively, and ranged from 6% to 100% in 4 sports studies. Due to poor methodological quality, the validity of these estimates is compromised.
