Our objectives were to evaluate and assess adequacy of vitamin D intake, serum levels, and association with bone mineral density. Assessments were completed using 3-day food records and dual energy x-ray absorptiometry scans. The spinal muscular atrophy type I cohort included 22 males and 18 females (N = 40), with a mean age of 18.6 months. Data collection occurred from 2001 to 2011. Seventy-five percent of patients had inadequate intake of vitamin D at the initial visit. Using mixed-effects analyses, vitamin D and calcium intakes correlated positively with bone mineral density ( r = 0.31 and r = 0.53, respectively). Increased vitamin D and calcium consumption were associated with an increase in bone mineral density ( P = .04 and P = .01, respectively). Vitamin D intake correlated positively with serum levels ( r = 0.65). Further study is needed to determine optimal intakes of vitamin D and calcium in the spinal muscular atrophy type I population.<\/jats:p>","DOI":"10.1177\/0883073812471857","type":"journal-article","created":{"date-parts":[[2013,1,18]],"date-time":"2013-01-18T23:10:29Z","timestamp":1358550629000},"page":"374-380","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["Vitamin D Intake Is Inadequate in Spinal Muscular Atrophy Type I Cohort"],"prefix":"10.1177","volume":"29","author":[{"given":"Jennifer","family":"Aton","sequence":"first","affiliation":[{"name":"Intermountain Healthcare, Murray, UT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca Hurst","family":"Davis","sequence":"additional","affiliation":[{"name":"Department of Neurology Pediatric Motor Disorders Research Program, University of Utah, Salt Lake City, UT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristine C.","family":"Jordan","sequence":"additional","affiliation":[{"name":"Division of Nutrition, University of Utah, Salt Lake City, UT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles B.","family":"Scott","sequence":"additional","affiliation":[{"name":"CBS Squared Inc, Fort Washington, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathryn J.","family":"Swoboda","sequence":"additional","affiliation":[{"name":"Department of Neurology Pediatric Motor Disorders Research Program, University of Utah, Salt Lake City, UT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,1,17]]},"reference":[{"key":"bibr1-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(95)90460-3"},{"key":"bibr2-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1086\/302369"},{"key":"bibr3-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/0960-8966(91)90039-U"},{"key":"bibr4-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/0960-8966(92)90006-R"},{"key":"bibr5-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.26.12.761"},{"key":"bibr6-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.15.6.409"},{"key":"bibr7-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320410216"},{"key":"bibr8-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1177\/0883073807305673"},{"key":"bibr9-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1995.00540290108025"},{"key":"bibr10-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/0960-8966(91)90052-T"},{"key":"bibr11-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(80)90847-8"},{"key":"bibr12-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000290830.40544.b9"},{"key":"bibr13-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1177\/0883073807305788"},{"key":"bibr14-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/j.cuor.2006.09.006"},{"key":"bibr15-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1097\/CND.0b013e318183e0fa"},{"key":"bibr16-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1002\/path.2566"},{"key":"bibr17-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/j.nmd.2007.05.008"},{"key":"bibr18-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.2006.02683.x"},{"key":"bibr19-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1007\/s00774-011-0294-4"},{"key":"bibr20-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/S1043-2760(00)00336-2"},{"key":"bibr21-0883073812471857","first-page":"215","volume":"9","author":"Lee BJ","year":"2009","journal-title":"J Musculoskelet Neuronal Interact"},{"key":"bibr22-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1177\/0883073807305664"},{"key":"bibr23-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.63B4.7298675"},{"key":"bibr24-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1177\/0883073807305670"},{"key":"bibr25-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/S1071-9091(98)80026-0"},{"key":"bibr26-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/j.nmd.2009.03.009"},{"key":"bibr27-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/j.nmd.2012.04.008"},{"key":"bibr28-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1016\/0887-8994(94)00100-G"},{"key":"bibr29-0883073812471857","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0012140"},{"key":"bibr30-0883073812471857","unstructured":"Pronsky ZM.
