The epidemiology of XXXX in senior football: a systematic review of prospective studies.

@entity1 @entity5149 @entity130
BACKGROUND: Groin injuries are troublesome in @entity1 's and @entity1 's football. AIM: To review the literature on the epidemiology of @entity130 in senior football and compare injury occurrence between sexes. METHODS: Studies were identified through a search of PubMed, EMBASE, CINAHL and Web of Science, in the reference lists of the selected articles and the authors' bibliographies. The number of injuries, percentage of @entity130 from all injuries and rate of @entity130 per 1000   h were extracted. Exposure and injury data were aggregated across included studies and the absolute differences in @entity130 proportion and rate of @entity130 were compared between sexes. Risk of bias was assessed using a 5-item checklist. RESULTS: 34 articles met the study criteria and were included. The proportion of @entity130 in @entity5149 was 4-19% in @entity1 and 2-14% in @entity1 . Aggregated data analysis (29 studies) showed a higher relative proportion of @entity130 in @entity1 than in @entity1 (12.8% vs 6.9%, absolute difference 5.9%, 95% CI 4.6% to 7.1%). The rate of @entity130 varied from 0.2 to 2.1/1000   h in @entity1 and 0.1 to 0.6/1000   h in @entity1 's club football, and aggregated analysis (23 studies) showed a more than two-fold higher rate in @entity1 (0.83/1000 h vs 0.35/1000   h, rate ratio 2.4, 95% CI 2.0 to 2.9). High risk of bias was identified for @entity1 selection (18 studies), exposure (17 studies) and precision estimate (16 studies). CONCLUSIONS: Groin injuries are frequent in senior football and are more common in @entity1 than @entity1 . Future research needs to be of higher quality.
