Methods: Children (6\u201312 y, n = 101) with a body mass index (BMI)-for-age &gt;85th percentile were randomized to six dietitian-led behavior counselling sessions or no intervention. Plasma 25-hydroxyvitamin D (25(OH)D), anthropometry, and body composition using dual-energy X-ray absorptiometry were assessed every 3 months for 1 year. For each anthropometry variable (z-scores), tertiles were created to test for differences in 25(OH)D over time (tertile-by-time), and for changes in the z-score (loss, maintain, gain)-by-time, and according to fat patterning (android vs. gynoid) using mixed effects models. Results: The baseline plasma 25(OH)D was 62.2 nmol\/L (95%CI: 58.7\u201365.7), and none &lt; 30 nmol\/L. At 6 mo, children with gynoid fat patterning had higher 25(OH)D concentrations than in those with android fat patterning (64.5 \u00b1 1.1 nmol\/L vs. 50.4 \u00b1 1.0 nmol\/L, p &lt; 0.003, Cohen\u2019s f = 0.20). Children with the lowest lean mass index z-score at 9 mo had higher plasma 25(OH)D concentrations than children with the highest z-score at baseline, 3 mo, and 6 mo (p &lt; 0.05, Cohen\u2019s f = 0.20). No other significant differences were observed. Conclusion: In this longitudinal study, vitamin D deficiency was not present in children 6\u201312 y of age with obesity. Reductions in adiposity did not alter the vitamin D status.<\/jats:p>","DOI":"10.3390\/nu14153153","type":"journal-article","created":{"date-parts":[[2022,8,1]],"date-time":"2022-08-01T04:04:00Z","timestamp":1659326640000},"page":"3153","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Associations between Body Composition and Vitamin D Status in Children with Overweight and Obesity Participating in a 1-Year Lifestyle Intervention"],"prefix":"10.3390","volume":"14","author":[{"given":"Popi","family":"Kasvis","sequence":"first","affiliation":[{"name":"Department of Clinical Nutrition, McGill University Health Centre, Montreal, QC H4A 3J1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamara R.","family":"Cohen","sequence":"additional","affiliation":[{"name":"Faculty of Land and Food Systems| Food, Nutrition and Health, University of British Columbia, Vancouver, BC V6T 1Z4, Canada"},{"name":"Healthy Starts, BC Children\u2019s Hospital Research Institute, Vancouver, BC V5Z 4H4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah-\u00c8ve","family":"Loiselle","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, McGill University Health Centre, Montreal, QC H4A 3J1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom J.","family":"Hazell","sequence":"additional","affiliation":[{"name":"Department of Kinesiology & Physical Education, Wilfrid Laurier University, Waterloo, ON N2L 3C5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine A.","family":"Vanstone","sequence":"additional","affiliation":[{"name":"School of Human Nutrition, McGill University, Montreal, QC H3A 0G4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hope A.","family":"Weiler","sequence":"additional","affiliation":[{"name":"School of Human Nutrition, McGill University, Montreal, QC H3A 0G4, Canada"},{"name":"Nutrition Research Division, Bureau of Nutritional Sciences, Food Directorate, Health Products and Food Branch, Health Canada, Ottawa, ON K1A 0K9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,30]]},"reference":[{"key":"ref_1","first-page":"194","article-title":"Childhood overweight and obesity trends in Canada","volume":"36","author":"Rao","year":"2016","journal-title":"Health Promot.
