This study aimed to fill the data gap in Western Romania by measuring 25-hydroxy-vitamin D levels in a cohort of 7141 from Arad County. It was observed that women, younger adults (18\u201329 years), and older adults (70\u201379 years) had notably lower vitamin D levels compared to the average population. Additionally, there was a rise in vitamin D levels over the four-year span of 2018\u20132022, coinciding with the COVID-19 pandemic. Our research provides fresh data on those most susceptible to vitamin D deficiency and lays the groundwork for educational campaigns on vitamin D supplementation benefits.<\/jats:p>","DOI":"10.3390\/life14020274","type":"journal-article","created":{"date-parts":[[2024,2,19]],"date-time":"2024-02-19T10:40:15Z","timestamp":1708339215000},"page":"274","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Retrospective Analysis of Vitamin D Deficiency in an Adult Population of Arad County, Western Romania (2019\u20132022)"],"prefix":"10.3390","volume":"14","author":[{"given":"Daniela Teodora","family":"Marti","sequence":"first","affiliation":[{"name":"Department of Biology and Life Sciences, Faculty of Medicine, Vasile Goldis Western University of Arad, 310025 Arad, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandru","family":"Nesiu","sequence":"additional","affiliation":[{"name":"Department of Biology and Life Sciences, Faculty of Medicine, Vasile Goldis Western University of Arad, 310025 Arad, Romania"},{"name":"\u201cAurel Ardelean\u201d Institute of Life Sciences, Vasile Goldis Western University of Arad, 86 Rebreanu, 310414 Arad, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5734-0071","authenticated-orcid":false,"given":"Cornel","family":"Balta","sequence":"additional","affiliation":[{"name":"\u201cAurel Ardelean\u201d Institute of Life Sciences, Vasile Goldis Western University of Arad, 86 Rebreanu, 310414 Arad, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1094-3729","authenticated-orcid":false,"given":"Tudor Rares","family":"Olariu","sequence":"additional","affiliation":[{"name":"Discipline of Parasitology, Department of Infectious Disease, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Center for Diagnosis and Study of Parasitic Diseases, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Clinical Laboratory, Municipal Clinical Emergency Teaching Hospital, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5218-9026","authenticated-orcid":false,"given":"Alin Gabriel","family":"Mihu","sequence":"additional","affiliation":[{"name":"Department of Biology and Life Sciences, Faculty of Medicine, Vasile Goldis Western University of Arad, 310025 Arad, Romania"},{"name":"\u201cAurel Ardelean\u201d Institute of Life Sciences, Vasile Goldis Western University of Arad, 86 Rebreanu, 310414 Arad, Romania"},{"name":"Bioclinica Medical Analysis Laboratory, Dreptatii Street, nr. 23, 310300 Arad, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8510-6653","authenticated-orcid":false,"given":"Anca","family":"Hermenean","sequence":"additional","affiliation":[{"name":"Department of Biology and Life Sciences, Faculty of Medicine, Vasile Goldis Western University of Arad, 310025 Arad, Romania"},{"name":"\u201cAurel Ardelean\u201d Institute of Life Sciences, Vasile Goldis Western University of Arad, 86 Rebreanu, 310414 Arad, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela Adriana","family":"Oatis","sequence":"additional","affiliation":[{"name":"Department of Biology and Life Sciences, Faculty of Medicine, Vasile Goldis Western University of Arad, 310025 Arad, Romania"},{"name":"\u201cAurel Ardelean\u201d Institute of Life Sciences, Vasile Goldis Western University of Arad, 86 Rebreanu, 310414 Arad, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"147","DOI":"10.1016\/j.ahj.2021.05.012","article-title":"Potential Impact of the Steroid Hormone, Vitamin D, on the Vasculature","volume":"239","author":"Tintut","year":"2021","journal-title":"Am.
