The purpose of this study was to prospectively assess the vitamin D (VD) status in newly admitted psychogeriatric patients, and to study the correlation of VD status with indicators of calcium metabolism.MethodsA valid VD sample, as measured by serum 25-hydroxyvitamin D (25-OHD), was obtained from nine consecutive psycogeriatric inpatients (66% women), during a one-month period in 2011. The Research Ethics Boards at St. Joseph\u2019s Healthcare Hamilton approved this project.ResultsAll participants showed VD inadequacy (defined as 25-OHD \u2264 75 nmol\/L) with a mean level of serum 25-OHD of 45.5 \u00b1 14.6 (range 28.5\u201373.4) nmol\/L. None of the patients in the sample met criteria for VD deficiency (currently defined by expert consensus as 25-OHD &lt; 25 nmol\/L). Mean serum VD levels were lower in females (38.8 \u00b1 9.8 nmol\/L) than in males(59.0 \u00b1 14.3 nmol\/L), p = .03. Magnesium and PTH were both higher in females (p = .03 and .02, respectively). Univariate linear regression analysis showed that VD levels were strongly negatively associated with magnesium (p = .001) and PTH (p = .02).ConclusionSince research links VD deficiency to psychiatric conditions, high rates of insufficiency in this population is very common and routine supplements are strongly suggested, regardless of patients\u2019 living environment.<\/jats:p>","DOI":"10.5770\/cgj.15.39","type":"journal-article","created":{"date-parts":[[2012,12,4]],"date-time":"2012-12-04T16:02:11Z","timestamp":1354636931000},"page":"80-84","source":"Crossref","is-referenced-by-count":4,"title":["Hypovitaminosis D: A Contributor to Psychiatric Disorders in Elderly?"],"prefix":"10.5770","volume":"15","author":[{"given":"Jennifer","family":"Ford","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana","family":"Hategan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James A.","family":"Bourgeois","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel K.","family":"Tisi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3968","published-online":{"date-parts":[[2012,8,1]]},"container-title":["Canadian Geriatrics Journal"],"original-title":[],"link":[{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/download\/39\/79","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/download\/39\/86","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/download\/39\/79","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,9,8]],"date-time":"2021-09-08T21:44:43Z","timestamp":1631137483000},"score":1,"resource":{"primary":{"URL":"https:\/\/cgjonline.ca\/index.php\/cgj\/article\/view\/39"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,8,1]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2012,9,20]]}},"URL":"https:\/\/doi.org\/10.5770\/cgj.15.39","relation":{},"ISSN":["1925-8348"],"issn-type":[{"value":"1925-8348","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,8,1]]}}}
