Analysis for ferritin included boys and nonpregnant girls aged 1 to 17 years. Analyses for zinc and vitamin A included children aged 1 to 4 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean 2010 to 2005 differences in ferritin, zinc, and vitamin A were 2.5 \u00b5g\/L (95% confidence interval [CI]: 1.3 to 3.7), \u221234.9 \u00b5g\/dL (95% CI: \u221239.6 to \u221230.2), and \u221211.5 \u00b5g\/dL (95% CI: \u221212.3 to \u221210.7), respectively, after adjusting for sociodemographic characteristics. These differences varied significantly by region of residence. In 2010, region of residence was a significant correlate for all 3 micronutrients. Other important correlates included age and maternal education for ferritin and body mass index-for-age Z score, maternal education, wealth index, food insecurity, and urbanicity for vitamin A.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Plasma ferritin was slightly higher in 2010 than in 2005, whereas serum zinc and vitamin A were substantially lower in 2010. In the absence of obvious causal explanations, it is uncertain whether this decline represents a worsening of micronutrient status in Colombian children or an artifact due to systematic laboratory or data management errors incurred in the surveys.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0379572117700976","type":"journal-article","created":{"date-parts":[[2017,3,30]],"date-time":"2017-03-30T23:05:47Z","timestamp":1490915147000},"page":"146-157","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Trends in Iron, Zinc, and Vitamin A Status Biomarkers Among Colombian Children: Results From 2 Nationally Representative Surveys"],"prefix":"10.1177","volume":"38","author":[{"given":"Wenchao","family":"Li","sequence":"first","affiliation":[{"name":"Department of Epidemiology, University of Michigan School of Public Health, Ann Arbor, MI, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar F.","family":"Herr\u00e1n","sequence":"additional","affiliation":[{"name":"Faculty of Health, Industrial University of Santander, Bucaramanga, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo","family":"Villamor","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, University of Michigan School of Public Health, Ann Arbor, MI, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,3,30]]},"reference":[{"issue":"2","key":"bibr1-0379572117700976","first-page":"105","volume":"49","author":"Monteiro CA","year":"1995","journal-title":"Eur J Clin Nutr"},{"key":"bibr2-0379572117700976","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(13)60937-X"},{"key":"bibr3-0379572117700976","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(07)61235-5"},{"key":"bibr4-0379572117700976","doi-asserted-by":"publisher","DOI":"10.3945\/ajcn.112.034868"},{"key":"bibr5-0379572117700976","doi-asserted-by":"publisher","DOI":"10.3945\/jn.115.220079"},{"key":"bibr6-0379572117700976","doi-asserted-by":"publisher","DOI":"10.1177\/15648265070284S409"},{"key":"bibr7-0379572117700976","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/75.6.1062"},{"key":"bibr8-0379572117700976","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2006-3481"},{"key":"bibr9-0379572117700976","doi-asserted-by":"publisher","DOI":"10.1016\/S2214-109X(15)00039-X"},{"key":"bibr10-0379572117700976","unstructured":"World Health Organization.
