Evidence suggests the baseline risk for vitamin D (vitD) deficiency is increased among immigrants who move from equatorial to northern countries. We investigated the prevalence and determinants of vitD deficiency\/insufficiency among first-generation immigrants compared with native-born Canadians and identified explanatory covariables. We used a cross-sectional design with data from the national Canadian Health Measures Survey (Cycles 3 and 4) (11,579 participants aged 3\u201379 years). We assessed serum 25-hydroxyvitamin D (S-25(OH)D) levels, sociodemographic and environmental factors, immigration status, length of time in Canada, vitD-rich food intake, ethnicity, and place of birth. Immigrants had lower mean S-25(OH)D than non-immigrants (51.23 vs. 62.72 nmol\/L, p &lt; 0.001). Those with younger age at the time of immigration (&lt;18 years) had a high risk for low vitD, and S-25(OH)D levels increased with the length of time they had lived in Canada. The highest deficiency levels were in immigrants born in Morocco, India, and Lebanon compared with native-born Canadians. Ethnicity was the factor most strongly associated with S-25(OH)D. Compared with the white ethnic grouping, the Japanese had the highest level of vitD deficiency, followed by Arabs and Southeast Asians. Ethnic variations, dietary intake, and lifestyle factors are the main predictors of\/explanatory factors for vitD status among Canadian immigrants.<\/jats:p>","DOI":"10.3390\/nu13082702","type":"journal-article","created":{"date-parts":[[2021,8,5]],"date-time":"2021-08-05T09:35:32Z","timestamp":1628156132000},"page":"2702","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Vitamin D Status among First-Generation Immigrants from Different Ethnic Groups and Origins: An Observational Study Using the Canadian Health Measures Survey"],"prefix":"10.3390","volume":"13","author":[{"given":"Said","family":"Yousef","sequence":"first","affiliation":[{"name":"School of Epidemiology and Public Health, Faculty of Medicine, University of Ottawa, Ottawa, ON K1H 8M5, Canada"},{"name":"Cardiovascular Research Methods Centre, University of Ottawa Heart Institute, Ottawa, ON K1Y 4W7, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Douglas","family":"Manuel","sequence":"additional","affiliation":[{"name":"Ottawa Hospital Research Institute, Ottawa, ON K1Y 4E9, Canada"},{"name":"Institute for Clinical Evaluative Sciences, Ottawa, ON K1Y 4E9, Canada"},{"name":"Department of Family Medicine, Faculty of Medicine, University of Ottawa, Ottawa, ON K1H 8M5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian","family":"Colman","sequence":"additional","affiliation":[{"name":"School of Epidemiology and Public Health, Faculty of Medicine, University of Ottawa, Ottawa, ON K1H 8M5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manny","family":"Papadimitropoulos","sequence":"additional","affiliation":[{"name":"Eli Lilly Canada Inc., Toronto, ON M5X 1B1, Canada"},{"name":"Faculty of Pharmacy, University of Toronto, Toronto, ON M5S 3M2, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alomgir","family":"Hossain","sequence":"additional","affiliation":[{"name":"School of Epidemiology and Public Health, Faculty of Medicine, University of Ottawa, Ottawa, ON K1H 8M5, Canada"},{"name":"Institute for Clinical Evaluative Sciences, Ottawa, ON K1Y 4E9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7970-2616","authenticated-orcid":false,"given":"MoezAlIslam","family":"Faris","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition and Dietetics, College of Health Sciences\/Research Institute of Medical and Health Sciences (RIMHS), University of Sharjah, Sharjah 27272, United Arab Emirates"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George A.","family":"Wells","sequence":"additional","affiliation":[{"name":"School of Epidemiology and Public Health, Faculty of Medicine, University of Ottawa, Ottawa, ON K1H 8M5, Canada"},{"name":"Cardiovascular Research Methods Centre, University of Ottawa Heart Institute, Ottawa, ON K1Y 4W7, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1082","DOI":"10.1016\/j.jcot.2019.07.004","article-title":"Vitamin D for skeletal and non-skeletal health: What we should know","volume":"10","author":"Charoenngam","year":"2019","journal-title":"J.
