The main objective of the study was to determine the vitamin A status of Zambian children less than five years of age in a community where strategies of vitamin A supplementation and consumption of vitamin A fortified sugar have been introduced. In a cross-sectional study, a total of 537 children were enrolled. Their vitamin A status was measured using the modified relative dose response (MRDR) test. Their vitamin A status was compared to the status measured using a similar method in 1996, before vitamin A supplementation through capsule distribution and fortification of sugar was implemented as strategies to reduce vitamin A deficiency in the country. Results showed that the vitamin A status of children improved markedly as a result of these strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
