RT Journal Article SR Electronic T1 Gender data gap in military research: a review of the participation of men and women in military musculoskeletal injury studies JF BMJ Military Health JO BMJ Mil Health FD British Medical Journal Publishing Group SP e002015 DO 10.1136/bmjmilitary-2021-002015 A1 Thomas J O'Leary A1 C D Young A1 S L Wardle A1 J P Greeves YR 2022 UL http://militaryhealth.bmj.com/content/early/2022/01/17/bmjmilitary-2021-002015.abstract AB Servicewomen are at increased risk of musculoskeletal injuries compared with their male counterparts, but women are under-represented in sports medicine research. The aim of this review was to assess the representation of women in military musculoskeletal injury studies. PubMed was searched for human original research studies using the terms Military OR Army OR Navy OR ‘Air Force’ AND ‘musculoskeletal injury’. Each study was categorised as epidemiology (basic training), epidemiology (trained personnel), risk factors, interventions and other. The number of male and female participants was retrieved from each study. A total of 262 studies were included: 98 (37%) studies only included men, 17 (6%) studies only included women and 147 (56%) studies included both men and women. A total of 8 051 778 participants were included in these studies (men: 6 711 082, 83%; women: 1 340 696, 17%). The study theme with the greatest proportion of women was musculoskeletal injury epidemiology studies in a basic training population (20% of participants) with the lowest proportion of women in intervention trials (6% of participants). These data suggest women are not under-represented in military musculoskeletal injury studies when considering the gender representation of most militaries. Our data are, however, biased by large epidemiological trials and women were under-represented in intervention trials. The under-representation of women in intervention trials could be due to difficulties in controlling for the effects of female sex steroids on musculoskeletal outcomes, or a focus on interventions in the most arduous military roles where injury risk is highest and women have been previously excluded.All data relevant to the study are included in the article or uploaded as supplementary information.
