Orthorexia nervosa tendencies before and during COVID\u201019 were assessed using ORTO\u201011 and ORTO\u201015. Physical activity and anthropometric data were collected for both recalled pre\u2010pandemic and pandemic periods, while energy and macronutrient intakes were assessed using a retrospective 24\u2010h dietary recall. Data were analyzed using paired tests, effect sizes (ES), and multivariate linear regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>During the pandemic, dancers reported approximately 50% lower weekly dance frequency and daily dance duration than recalled pre\u2010pandemic values, with large and significant effect sizes. Significant decreases were observed in ORTO\u201011 and ORTO\u201015 scores, indicating an increase in orthorexic tendencies. Pandemic\u2010period self\u2010reported body weight was higher than pre\u2010pandemic body weight, whereas BMI did not differ significantly between the recalled pre\u2010pandemic and pandemic\u2010period assessments. In multivariate analyses, female sex remained an independent predictor for both ORTO\u201011 and ORTO\u201015 scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Compared with recalled pre\u2010pandemic scores, pandemic\u2010period ORTO\u201011 and ORTO\u201015 scores were lower, suggesting higher ORTO\u2010measured health\u2010oriented eating tendencies among dancers. Given the retrospective self\u2010report design and the methodological limitations of ORTO\u2010based instruments, these findings should not be interpreted as evidence of clinical ON prevalence or precise longitudinal change. Nevertheless, these ORTO\u2010measured tendencies appeared to differ not only behaviorally but also in relation to nutrient intake patterns. Female sex was associated with pandemic\u2010period ORTO scores, but this finding should be interpreted cautiously because psychological, sociocultural, and clinical variables were not assessed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jhn.70324","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T10:25:12Z","timestamp":1785752712000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["ORTO\u2010Measured Orthorexia Nervosa\u2010Related Tendencies Among Dancers Before and During the COVID\u201019 Pandemic: A Multivariate Analysis"],"prefix":"10.1111","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0139-676X","authenticated-orcid":false,"given":"Tugce","family":"Ozlu Karahan","sequence":"first","affiliation":[{"name":"Hamidiye Faculty of Health Sciences, Department of Nutrition and Dietetics University of Health Sciences Istanbul Uskudar T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4761-6836","authenticated-orcid":false,"given":"Emre Batuhan","family":"Kenger","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Department of Nutrition and Dietetics Istanbul Bilgi University Istanbul Beyoglu T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Demet","family":"Tekin","sequence":"additional","affiliation":[{"name":"Labranza Flamenco Dance Company Istanbul Kadikoy T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6407-4648","authenticated-orcid":false,"given":"Ani","family":"Agopyan","sequence":"additional","affiliation":[{"name":"Faculty of Sports Sciences, Department of Coaching Education Marmara University Istanbul Beykoz T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2025.1705064"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/nu15020379"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eatbeh.2015.12.006"},{"key":"e_1_2_12_5_1","first-page":"42","article-title":"Health Food Junkie: Obsession With Dietary Perfection Can Sometimes Do More Harm Than Good, Says One Who Has Been There","volume":"136","author":"Bratman S.","year":"1997","journal-title":"Yoga Journal"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40519-018-0606-y"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-244X-14-59"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40519-023-01601-z"},{"issue":"4","key":"e_1_2_12_9_1","first-page":"313","article-title":"Orthorexia or When a Healthy Diet Becomes an Obsession","volume":"57","author":"Bartrina J.
