This study examined correlations between serum essential trace element concentrations and polysomnography-confirmed OSA.Methods: This cross-sectional study included patients recruited from the Sleep Disorders Center of Farabi Hospital in western Iran. Participants were classified as patients with OSA (n=54) or controls without OSA (n=45).Results: Iron (Fe) levels were significantly higher in participants with OSA than in controls (p=0.04). Higher Fe levels were associated with greater odds of OSA (p for trend=0.02). Participants in the fourth Fe quartile had higher odds of OSA than those in the lowest quartile, although this association was of borderline statistical significance (odds ratio [OR], 3.00; 95% confidence interval [CI], 0.96 to 10.00; p=0.06). In contrast, participants in the second and third magnesium (Mg) quartiles had lower odds of OSA than those in the first quartile (Q2: OR, 0.31; 95% CI, 0.09 to 0.96; Q3: OR, 0.26; 95% CI, 0.07 to 0.82). In the generalized weighted quantile sum regression model, the association between the metal mixture and OSA was not statistically significant (\u03b2=\u20130.22, p=0.59).Conclusions: Serum concentrations of selected micronutrients may be associated with OSA. The findings suggested a positive association between higher Fe concentrations and OSA, whereas intermediate Mg concentrations were associated with lower odds of OSA.<\/jats:p>","DOI":"10.3961\/jpmph.25.904","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T12:48:08Z","timestamp":1787921288000},"page":"498-508","update-policy":"https:\/\/doi.org\/10.3961\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Association
