This report summarizes available data on the prevalence of vitamin A, iodine, and iron deficiencies and reports on the implementation and progress of programs to battle these deficiencies in developing countries. It sets a reference point by which priorities for program content and coverage can be better informed and a baseline from which progress in deficiency prevention can be measured. In part 1, prevalence trends for deficiencies of vitamin A, iodine, and iron are summarized. Part 2 describes the status of current programs aimed at preventing or reducing micronutrient deficiencies. The report is illustrated with numerous statistical tables, figures, and maps.
