We examined the factors associated with ferritin concentration in 30 female varsity athletes (18\u201330 years) at the University of British Columbia in Vancouver, Canada. Biochemical indicators of iron and inflammation status, dietary intake, supplementation practices, weight, height, and menstrual blood losses were assessed. Iron deficiency prevalence was 20% (n = 6\/30; inflammation-adjusted ferritin &lt;15 \u03bcg\/L). Multiple linear regression was used to assess the associations of a number of independent explanatory variables with log-transformed serum ferritin (\u03bcg\/L) as the continuous outcome variable. A 1-unit increase in body mass index (BMI; kg\/m<jats:sup>2<\/jats:sup>) was associated with 22% (95% CI: 9%\u201337%) higher mean ferritin concentrations, and a 1-point increase in menstrual loss score was associated with 1% (95% CI: 1%\u20132%) lower ferritin concentrations. Hemoglobin and hepcidin concentrations, inflammation biomarkers, consumption of iron supplements in any form or dose for \u22653 days\/week, and age were not significantly associated with ferritin concentrations in the final adjusted model. <\/jats:p><jats:p> Novelty Estimated monthly menstrual losses and BMI were associated with serum ferritin concentrations in female athletes in our study. These are easy-to-measure, noninvasive measurements that should be considered in the assessment of risk of iron deficiency in female athletes. <\/jats:p>","DOI":"10.1139\/apnm-2019-0436","type":"journal-article","created":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T21:33:18Z","timestamp":1577136798000},"page":"723-730","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Menstrual blood losses and body mass index are associated with serum ferritin concentrations among female varsity athletes"],"prefix":"10.1139","volume":"45","author":[{"given":"Cara","family":"Mayer","sequence":"first","affiliation":[{"name":"Food, Nutrition and Health, Faculty of Land and Food Systems, University of British Columbia, 2205 East Mall, Vancouver, BC V6T 1Z4, Canada."},{"name":"British Columbia Children\u2019s Hospital Research Institute, 938 West 28th Avenue, Vancouver, BC V5Z 4H4, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikaela K.","family":"Barker","sequence":"additional","affiliation":[{"name":"Food, Nutrition and Health, Faculty of Land and Food Systems, University of British Columbia, 2205 East Mall, Vancouver, BC V6T 1Z4, Canada."},{"name":"British Columbia Children\u2019s Hospital Research Institute, 938 West 28th Avenue, Vancouver, BC V5Z 4H4, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Payge","family":"Dirk","sequence":"additional","affiliation":[{"name":"Food, Nutrition and Health, Faculty of Land and Food Systems, University of British Columbia, 2205 East Mall, Vancouver, BC V6T 1Z4, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelsey M.","family":"Moore","sequence":"additional","affiliation":[{"name":"Food, Nutrition and Health, Faculty of Land and Food Systems, University of British Columbia, 2205 East Mall, Vancouver, BC V6T 1Z4, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emma","family":"McCrudden","sequence":"additional","affiliation":[{"name":"School of Kinesiology, Faculty of Education, University of British Columbia, 6081 University Boulevard, Vancouver, BC V6T 1Z1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Crystal D.","family":"Karakochuk","sequence":"additional","affiliation":[{"name":"Food, Nutrition and Health, Faculty of Land and Food Systems, University of British Columbia, 2205 East Mall, Vancouver, BC V6T 1Z4, Canada."},{"name":"British Columbia Children\u2019s Hospital Research Institute, 938 West 28th Avenue, Vancouver, BC V5Z 4H4, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1080\/14767058.2018.1482871"},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1097\/MOG.0b013e32831ef1f7"},{"key":"refg3\/ref3","doi-asserted-by":"publisher","DOI":"10.1123\/ijsn.8.3.223"},{"key":"refg5\/ref5","doi-asserted-by":"publisher","DOI":"10.1016\/0167-5699(94)90137-6"},{"key":"refg6\/ref6","doi-asserted-by":"publisher","DOI":"10.1093\/jn\/136.10.2594"},{"key":"refg7\/ref7","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/71.6.1563"},{"key":"refg8\/ref8","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/79.3.437"},{"key":"refg9\/ref9","doi-asserted-by":"publisher","DOI":"10.1249\/jsr.0b013e31829a6f6b"},{"key":"refg10\/ref10","doi-asserted-by":"publisher","DOI":"10.1186\/1475-2891-13-71"},{"issue":"11","key":"refg11\/ref11","first-page":"1331","volume":"56","author":"Durmi\u0107 T.","year":"2016","journal-title":"J.
