The role of combined calcium and vitamin D (25-OHD) deficiency and subsequent supplementation has been well described in the literature, but the role of 25-OHD deficiency alone is less well understood, particularly its influence on recovery once a stress fracture has been incurred.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Retrospective data of recruits who had incurred stress fractures were collected (n=37). Independent-samples t-tests were conducted in Microsoft Excel to investigate the association between serum-25 OHD and the time taken to recover.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Significant differences (p&lt;0.05) were found in the mean time taken to recover from stress fractures when participants were grouped according to serum 25-OHD level.

The sample population of this study was too small to contribute to the discussion about whether a minimum serum 25-OHD status should be met before entering British Army training, but a larger prospective study should be able to provide the data required for a cost benefit analysis to be conducted and a decision made.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/jramc-2018-000983","type":"journal-article","created":{"date-parts":[[2018,10,16]],"date-time":"2018-10-16T00:05:10Z","timestamp":1539648310000},"page":"240-242","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":22,"title":["British Army recruits with low serum vitamin D take longer to recover from stress fractures"],"prefix":"10.1136","volume":"166","author":[{"given":"Thomas","family":"Richards","sequence":"first","affiliation":[{"name":"Imperial College Healthcare NHS Trust, St Mary\u2019s Hospital, Praed Street, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Wright","sequence":"additional","affiliation":[{"name":"Imperial College Healthcare NHS Trust, St Mary\u2019s Hospital, Praed Street, London, UK"},{"name":"Defence Medical Services, Medical Directorate, Royal Centre for Defence Medicine, Birmingham, England"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,10,15]]},"reference":[{"key":"2025081308060975000_166.4.240.1","unstructured":"American Orthopaedic Foot and Ankle Society, Stress fracture .
