It affected primarily children. The main underlying cause was a deficient intake of pre-formed vitamin A, but infection and intestinal parasitism also played important roles. INCAP focused its efforts on overcoming this problem and developed, as a short-term solution, the technology to fortify sugar with vitamin A. Fortification programs were implemented in several Central American countries. Evaluation of these programs revealed a significant impact\u2014not only on vitamin A status, but also on iron nutrition and hematological condition. Longer-term solutions, like increasing the availability and consumption of vitamin A-rich foods, were later suggested and operational tools were developed to assist the countries in the region in the implementation, evaluation and monitoring of their own fortification programs.<\/jats:p>","DOI":"10.1177\/156482651003100112","type":"journal-article","created":{"date-parts":[[2015,11,25]],"date-time":"2015-11-25T16:02:18Z","timestamp":1448467338000},"page":"118-129","source":"Crossref","is-referenced-by-count":21,"title":["Five Decades of Vitamin A Studies in the Region of Central America and Panama"],"prefix":"10.1177","volume":"31","author":[{"given":"Guillermo","family":"Arroyave","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis A.","family":"Mej\u00eda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2010,3,10]]},"reference":[{"key":"bibr1-156482651003100112","unstructured":"Flores M, Reh E.
