Prevalence and severity of hip and groin pain in sub-elite male football: a cross-sectional cohort study of 695 players

The purpose of this study was twofold: (a) to investigate the prevalence of hip and groin pain in sub-elite male adult football in Denmark and (b) to explore the association between prevalence and duration of hip and groin pain in the previous season with the Copenhagen Hip and Groin Outcome Score (HAGOS) in the beginning of the new season. In total 695 respondents from 40 teams (Division 1-4) were included. Players completed in the beginning of the new season (July-Sept 2011) a self-reported paper questionnaire on hip and/or groin pain during the previous season and HAGOS. In total 49% (95% CI: 45-52%) reported hip and/or groin pain during the previous season. Of these, 31% (95% CI: 26-36%) reported pain for >6 weeks. Players with the longest duration of pain during the previous season had the lowest HAGOS scores, when assessed at the beginning of the new season, P < 0.001. This study documents that half of sub-elite male adult football players report pain in the hip and/or groin during a football season. The football players with the longest duration of pain in previous season displayed the lowest HAGOS scores in the beginning of the new season.
