Although anxiety and autonomic dysregulation have been implicated, the role of micronutrient status remains unclear. This study aimed to investigate the association between palpitations, micronutrient levels, and anxiety in adolescents and to evaluate the independent associations between selected micronutrients and palpitations using multivariable regression models. Methods: This case\u2013control study included 52 adolescents with palpitations and 52 frequency-matched healthy controls. Structural heart disease was excluded by electrocardiography, echocardiography, and 24-h Holter monitoring. Results: Adolescents with palpitations had significantly lower serum magnesium, selenium, and ferritin levels and higher anxiety scores than controls, despite most values remaining within reference ranges. In age- and sex-adjusted analyses, lower magnesium and selenium levels were independently associated with palpitations. Conclusions: Subclinical differences in micronutrient status, particularly magnesium and selenium, together with increased anxiety, may contribute to non-structural palpitations in adolescents. These findings support a more integrative evaluation that includes micronutrient and psychological assessment alongside standard cardiac investigations.<\/jats:p>","DOI":"10.3390\/nu18050717","type":"journal-article","created":{"date-parts":[[2026,2,24]],"date-time":"2026-02-24T12:19:23Z","timestamp":1771935563000},"page":"717","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Micronutrient Profiles and Anxiety in Adolescents with Non-Structural Palpitations: A Case\u2013Control Study"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3650-3518","authenticated-orcid":false,"given":"Damla","family":"Erden","sequence":"first","affiliation":[{"name":"Department of Pediatric Cardiology, Faculty of Medicine, Istanbul Atlas University, Istanbul 34408, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0143-4188","authenticated-orcid":false,"given":"Ajda","family":"Mutlu M\u0131h\u00e7\u0131o\u011flu","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Bak\u0131rk\u00f6y Dr. Sadi Konuk Training and Research Hospital, Istanbul 34147, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6364-8615","authenticated-orcid":false,"given":"Omer","family":"Okuyan","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine, Istanbul Atlas University, Istanbul 34408, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6547-9292","authenticated-orcid":false,"given":"Merve","family":"Tar\u0131","sequence":"additional","affiliation":[{"name":"Department of Clinical Psychology, Istanbul Atlas University Hospital, Istanbul 34203, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1347-8498","authenticated-orcid":false,"given":"Hafize","family":"Uzun","sequence":"additional","affiliation":[{"name":"Department of Medical Biochemistry, Faculty of Medicine, Istanbul Atlas University, Istanbul 34408, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"608","DOI":"10.4330\/wjc.v13.i11.608","article-title":"Cardiac monitoring for patients with palpitations","volume":"13","author":"Benito","year":"2021","journal-title":"World J.
