Serum retinol (SR) was measured at baseline and after 12 or 18 months (for VAFO). No sustained increase in SR was determined from the three-month VAC dosing regimen, and the prevalence of vitamin A deficiency (VAD) as assessed by SR (&lt; 20 mcg \/ dL) remained around 30 % (in line with national survey estimates over the previous 15 years). The major difference found was that 18 months of VAFO (of which 9 months had sustained promotion) was associated with reducing the prevalence of VAD to &lt; 10 %. The effective fortification and lack of effect of semi-annual VAC results are in line with previous studies; testing with dosing of VAC every three months is a new intervention. The results imply that promotion of fortified oil would reduce VAD in these conditions; whether it can replace or needs to be added to semi-annual VAC dosing remains to be determined. A phased changeover to reliance on fortified commodities (including oil) with careful monitoring of VAD trends is indicated. <\/jats:p>","DOI":"10.1024\/0300-9831\/a000077","type":"journal-article","created":{"date-parts":[[2013,2,2]],"date-time":"2013-02-02T02:22:37Z","timestamp":1359771757000},"page":"295-305","source":"Crossref","is-referenced-by-count":21,"title":["Effects on Vitamin A Deficiency in Children of Periodic High-Dose Supplements and of Fortified Oil Promotion in a Deficient Area of the Philippines"],"prefix":"10.31083","volume":"81","author":[{"given":"John B.","family":"Mason","sequence":"first","affiliation":[{"name":"Department of International Health and Development, Tulane University School of Public Health and Tropical Medicine, New Orleans, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria A.","family":"Ramirez","sequence":"additional","affiliation":[{"name":"Food and Nutrition Research Institute, Department of Science and Technology, Taguig City, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chona M.","family":"Fernandez","sequence":"additional","affiliation":[{"name":"Food and Nutrition Research Institute, Department of Science and Technology, Taguig City, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Regina","family":"Pedro","sequence":"additional","affiliation":[{"name":"Food and Nutrition Research Institute, Department of Science and Technology, Taguig City, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tina","family":"Lloren","sequence":"additional","affiliation":[{"name":"Department of International Health and Development, Tulane University School of Public Health and Tropical Medicine, New Orleans, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Saldanha","sequence":"additional","affiliation":[{"name":"Department of International Health and Development, Tulane University School of Public Health and Tropical Medicine, New Orleans, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Megan","family":"Deitchler","sequence":"additional","affiliation":[{"name":"Department of International Health and Development, Tulane University School of Public Health and Tropical Medicine, New Orleans, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Eisele","sequence":"additional","affiliation":[{"name":"Department of International Health and Development, Tulane University School of Public Health and Tropical Medicine, New Orleans, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","container-title":["International Journal for Vitamin and Nutrition Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0300-9831\/a000077","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T02:10:18Z","timestamp":1723169418000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/IJVNR\/81\/5\/10.1024\/0300-9831\/a000077"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,9,1]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2011,9,1]]}},"alternative-id":["10.1024\/0300-9831\/a000077"],"URL":"https:\/\/doi.org\/10.1024\/0300-9831\/a000077","relation":{},"ISSN":["0300-9831","1664-2821"],"issn-type":[{"value":"0300-9831","type":"print"},{"value":"1664-2821","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,9,1]]}}}
