However, the scarcity of studies investigating this association in non-psychiatric populations, such as working women, limits the generalizability of these findings. Therefore, this study aimed to investigate the association between common mental disorders (CMDs) and vitamin D deficiency\/insufficiency among female workers in southern Brazil. Methods: A cross-sectional study was conducted with a sample of 304 female workers from an industrial group in southern Brazil. Vitamin D deficiency\/insufficiency was defined as a serum 25(OH)D concentration of &lt;30 ng\/mL. CMDs were assessed using the Self-Reporting Questionnaire (SRQ-20), with a cutoff score of \u22658. The association between CMDs and vitamin D deficiency\/insufficiency was estimated using prevalence ratios (PRs) obtained through Poisson regression models adjusted for potential confounders. All analyses were stratified by age group (\u226440 years and &gt;40 years). Results: The \u226440-year group included 212 women (69.7%; mean age: 30.1 \u00b1 6.3 years), and the &gt;40-year group included 92 women (30.3%; mean age: 47.5 \u00b1 5.6 years). The prevalence of vitamin D deficiency\/insufficiency was 75.0% (95% confidence interval [CI]: 69.1\u201380.9) in women aged \u226440 years and 77.2% (95% CI: 68.4\u201385.9) in those aged &gt;40 years. After adjustment for potential confounding variables, among women older than 40 years, those with CMDs had a 25% higher probability of presenting vitamin D deficiency\/insufficiency compared to those without CMDs (PR = 1.25; 95% CI: 1.00\u20131.56; p = 0.044). Among women aged \u226440 years, no significant association was observed between CMDs and vitamin D deficiency\/insufficiency (PR = 1.10; 95% CI: 0.94\u20131.30; p = 0.226). Conclusions: The findings of this study indicate a significant association between common mental disorders and vitamin D deficiency\/insufficiency among female workers, particularly in those aged 40 years or older.<\/jats:p>","DOI":"10.3390\/nu18010025","type":"journal-article","created":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T08:35:27Z","timestamp":1766392527000},"page":"25","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Common Mental Disorders and Vitamin D Deficiency\/Insufficiency: A Cross-Sectional Study Among Female Workers in Southern Brazil"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8765-0759","authenticated-orcid":false,"given":"Ingrid St\u00e4hler","family":"Kohl","sequence":"first","affiliation":[{"name":"Post-Graduate Program in Medical Sciences: Endocrinology, Faculty of Medicine, Federal University of Rio Grande do Sul State, UFRGS, Porto Alegre 90610-264, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1111-4890","authenticated-orcid":false,"given":"Anderson","family":"Garcez","sequence":"additional","affiliation":[{"name":"Post-Graduate Program in Medical Sciences: Endocrinology, Faculty of Medicine, Federal University of Rio Grande do Sul State, UFRGS, Porto Alegre 90610-264, RS, Brazil"},{"name":"Post-Graduate Program in Food, Nutrition and Health, Faculty of Medicine, Federal University of Rio Grande do Sul, UFRGS, Porto Alegre 90610-264, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1354-3998","authenticated-orcid":false,"given":"Jana\u00edna Cristina da","family":"Silva","sequence":"additional","affiliation":[{"name":"Post-Graduate Program in Collective Health, University of Vale do Rio dos Sinos, Unisinos, S\u00e3o Leopoldo 93022-000, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1279-7080","authenticated-orcid":false,"given":"Harrison Canabarro de","family":"Arruda","sequence":"additional","affiliation":[{"name":"Post-Graduate Program in Food, Nutrition and Health, Faculty of Medicine, Federal University of Rio Grande do Sul, UFRGS, Porto Alegre 90610-264, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3186-9991","authenticated-orcid":false,"given":"Vera Maria Vieira","family":"Paniz","sequence":"additional","affiliation":[{"name":"Post-Graduate Program in Collective Health, University of Vale do Rio dos Sinos, Unisinos, S\u00e3o Leopoldo 93022-000, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3950-4594","authenticated-orcid":false,"given":"Maria Teresa Anselmo","family":"Olinto","sequence":"additional","affiliation":[{"name":"Post-Graduate Program in Medical Sciences: Endocrinology, Faculty of Medicine, Federal University of Rio Grande do Sul State, UFRGS, Porto Alegre 90610-264, RS, Brazil"},{"name":"Post-Graduate Program in Food, Nutrition and Health, Faculty of Medicine, Federal University of Rio Grande do Sul, UFRGS, Porto Alegre 90610-264, RS, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,20]]},"reference":[{"key":"ref_1","unstructured":"Goldberg, D.P., and Huxley, P.
