The goal of this study is to examine the association between saliva and serum 25(OH)D and knee OA. Methods: Serum and saliva 25(OH)D levels of 30 patients with knee OA and 30 matched healthy people in a control group were measured by ELISA. Knee pain was assessed by Western Ontario and McMaster Universities Arthritis Index (WOMAC). Data were analyzed through student\u2019s t-test, Pearson correlation test and receiver operating characteristic (ROC). Results: The mean serum and saliva 25(OH)D levels were lower in knee OA group than the healthy group. WOMAC negatively correlated with serum (r = -0.37; P = 0.02) and with unstimulated (r = -0.30; P = 0.04) saliva 25(OH)D. The unstimulated saliva 25(OH)D cutoff value was 27.8 pg\/m1 regarding the diagnosis of knee OA. Conclusion: Serum 25(OH)D levels were positively associated with saliva 25(OH)D, and 25(OH)D level in saliva, as in serum, was low in knee OA.<\/jats:p>","DOI":"10.18502\/jnfs.v8i1.11775","type":"journal-article","created":{"date-parts":[[2023,1,29]],"date-time":"2023-01-29T04:09:11Z","timestamp":1674965351000},"source":"Crossref","is-referenced-by-count":0,"title":["The Association between Saliva and Serum Vitamin D with Knee Osteoarthritis"],"prefix":"10.18502","author":[{"given":"Mohammad-Reza","family":"Mirzaii-Dizgah","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad-Hossein","family":"Mirzaii-Dizgah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iraj","family":"Mirzaii-Dizgah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roghayeh","family":"Koshkzari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7770","published-online":{"date-parts":[[2023,1,25]]},"container-title":["Journal of Nutrition and Food Security"],"original-title":[],"link":[{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JNFS\/article\/download\/11775\/11139","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JNFS\/article\/download\/11775\/11139","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T16:22:16Z","timestamp":1772209336000},"score":1,"resource":{"primary":{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JNFS\/article\/view\/11775"},"secondary":[{"URL":"https:\/\/jnfs.ssu.ac.ir\/article-1-475-en.html","label":"UNIVERSITY"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JNFS\/article\/view\/11775","label":"PUBLISHER"}]},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,1,25]]},"references-count":0,"URL":"https:\/\/doi.org\/10.18502\/jnfs.v8i1.11775","relation":{},"ISSN":["2476-7425","2476-7417"],"issn-type":[{"value":"2476-7425","type":"electronic"},{"value":"2476-7417","type":"print"}],"subject":[],"published":{"date-parts":[[2023,1,25]]}}}
