Therefore, the purpose of this study was to examine nutrition habits and AI among uninjured youth athletes. Athletic Identity Measurement Scale (AIMS) and custom Sports Nutrition Assessment for Consultation (SNAC) scores collected prospectively at local sporting events were retrospectively assessed via Mann\u2013Whitney, Kruskal\u2013Wallis, logistic regression, and ANCOVA tests (95% CI). Among 583 athletes (14.5 \u00b1 2.1 years; 59.9% female), the total AIMS scores did not differ by sex (males 39.9 \u00b1 7.2; females 39.3 \u00b1 7.5; maximum 70). The Social Identity (p = 0.009) and Exclusivity (p = 0.001) subscores were higher in males, while the Negative Affectivity subscores were lower (p = 0.019). Females reported frequent associations between SNAC and AIMS, particularly Negative Affectivity, which was positively associated with stress fracture history (p = 0.001), meal-skipping (p = 0.026), and desiring nutrition knowledge (p = 0.017). Males receiving weight recommendations reported higher Negative Affectivity subscores (p = 0.003), and higher total AIMS scores were observed in males with fatigue history (p = 0.004) and a desire for nutrition knowledge (p = 0.012). Fatigue and stress fracture history predominated in high-AI males and females, respectively, suggesting that poor sports nutrition may present differently by sex. As suboptimal nutrition was frequently related to high Negative Affectivity subscores, these habits may increase following poor sports performance.<\/jats:p>","DOI":"10.3390\/nu16172826","type":"journal-article","created":{"date-parts":[[2024,8,23]],"date-time":"2024-08-23T12:58:07Z","timestamp":1724417887000},"page":"2826","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Assessment of Sex-Specific Associations between Athletic Identity and Nutrition Habits in Competitive Youth Athletes"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4021-6362","authenticated-orcid":false,"given":"James J.","family":"McGinley","sequence":"first","affiliation":[{"name":"Center for Excellence in Sports Medicine, Scottish Rite for Children, Frisco, TX 75034, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3492-8442","authenticated-orcid":false,"given":"Nolan D.","family":"Hawkins","sequence":"additional","affiliation":[{"name":"Center for Excellence in Sports Medicine, Scottish Rite for Children, Frisco, TX 75034, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taylor","family":"Morrison","sequence":"additional","affiliation":[{"name":"Center for Excellence in Sports Medicine, Scottish Rite for Children, Frisco, TX 75034, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily","family":"Stapleton","sequence":"additional","affiliation":[{"name":"Department of Psychology, Scottish Rite for Children, Frisco, TX 75034, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily","family":"Gale","sequence":"additional","affiliation":[{"name":"Department of Psychology, Scottish Rite for Children, Frisco, TX 75034, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Janosky","sequence":"additional","affiliation":[{"name":"Sports Medicine Institute, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henry B.","family":"Ellis","sequence":"additional","affiliation":[{"name":"Center for Excellence in Sports Medicine, Scottish Rite for Children, Frisco, TX 75034, USA"},{"name":"Department of Orthopaedic Surgery, University of Texas Southwestern, Dallas, TX 75390, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6262-2054","authenticated-orcid":false,"given":"Sophia","family":"Ulman","sequence":"additional","affiliation":[{"name":"Center for Excellence in Sports Medicine, Scottish Rite for Children, Frisco, TX 75034, USA"},{"name":"Department of Orthopaedic Surgery, University of Texas Southwestern, Dallas, TX 75390, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"599","DOI":"10.55275\/JPOSNA-2023-599","article-title":"Nutritional Recommendations for the Young Athlete","volume":"5","author":"Hecht","year":"2023","journal-title":"J.
