Furthermore dancers may be under aesthetic pressure to maintain a lean physique, and adolescent dancers require extra nutrients for growth and development. This cross-sectional study investigated the nutritional status of 47 female adolescent ballet dancers (13\u201318 years) living in Auckland, New Zealand. Participants who danced at least 1 hr per day 5 days per week completed a 4-day estimated food record, anthropometric measurements (Dual-energy X-ray Absorptiometry) and hematological analysis (iron and vitamin D). Mean BMI was 19.7 \u00b1 2.4kg\/m<jats:sup>2<\/jats:sup> and percentage body fat, 23.5 \u00b1 4.1%. The majority (89.4%) of dancers had a healthy weight (5th-85th percentile) using BMI-for-age growth charts. Food records showed a mean energy intake of 8097.3 \u00b1 2155.6kJ\/day (48.9% carbohydrate, 16.9% protein, 33.8% fat, 14.0% saturated fat). Mean carbohydrate and protein intakes were 4.8 \u00b1 1.4 and 1.6 \u00b1 0.5g\/kg\/day respectively. Over half (54.8%) of dancers consumed less than 5g carbohydrate\/kg\/day, and 10 (23.8%) less than 1.2 g protein\/kg\/day. Over 60% consumed less than the estimated average requirement for calcium, folate, magnesium and selenium. Thirteen (28.3%) dancers had suboptimal iron status (serum ferritin (SF) &lt;20\u03bcg\/L). Of these, four had iron deficiency (SF &lt; 12\u03bcg\/L, hemoglobin (Hb) \u2265 120g\/L) and one iron deficiency anemia (SF &lt; 12\u03bcg\/L, Hb &lt; 120g\/L). Mean serum 25-hydroxy vitamin D was 75.1 \u00b1 18.6nmol\/L, 41 (91.1%) had concentrations above 50nmol\/L. Female adolescent ballet dancers are at risk for iron deficiency, and possibly inadequate nutrient intakes.<\/jats:p>","DOI":"10.1123\/ijsnem.2014-0089","type":"journal-article","created":{"date-parts":[[2014,11,10]],"date-time":"2014-11-10T21:40:06Z","timestamp":1415655606000},"page":"335-343","source":"Crossref","is-referenced-by-count":35,"title":["Dietary Intake, Anthropometric Characteristics, and Iron and Vitamin D Status of Female Adolescent Ballet Dancers Living in New Zealand"],"prefix":"10.1123","volume":"25","author":[{"given":"Kathryn L.","family":"Beck","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Mitchell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Foskett","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cathryn A","family":"Conlon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pamela R.","family":"Von Hurst","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","container-title":["International Journal of Sport Nutrition and Exercise Metabolism"],"original-title":[],"link":[{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/ijsnem\/25\/4\/article-p335.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.humankinetics.com\/downloadpdf\/journals\/ijsnem\/25\/4\/article-p335.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/journals.humankinetics.com\/downloadpdf\/journals\/ijsnem\/25\/4\/article-p335.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T02:58:34Z","timestamp":1724295514000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/ijsnem\/25\/4\/article-p335.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,8]]},"references-count":0,"journal-issue":{"issue":"4"},"URL":"https:\/\/doi.org\/10.1123\/ijsnem.2014-0089","relation":{},"ISSN":["1526-484X","1543-2742"],"issn-type":[{"value":"1526-484X","type":"print"},{"value":"1543-2742","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,8]]}}}
