Abstract: . . .  Nutrition Situation. United Nations, Geneva, Switzerland; 2000. 47. West KP: Extent of vitamin A deficiency among preschool children and women of reproductive age. J Nutrition 2002, 132:2857S-2866S. Knowledge of the extent of vitamin A deficiency is crucial for identifying high-risk populations and mobilizing resources for prevention. This report provides the most recent estimates of prevalence and numbers of pre- school-aged children suffering from vitamin A deficiency and xerophthal- mia by region for selected countries. 48.
