    AbstractThe 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.
