Preschool Child Vitamin A Deficiency Prevention

  • PREVIEW
  • READ ARTICLE
  • OPEN PDF

ISSN

Childhood vitamin A deficiency (VAD) is a major facet of hidden hunger, with 80 million deficient preschoolers in
Africa and Southern Asia alone. Multiple strategies exist to prevent VAD, including periodic, high-dose vitamin A supplementation (VAS), food fortification, dietary change and biofortification.  VAS prevents xerophthalmia, blindness, child mortality and hearing loss, but does not normalize serum retinol, which is only achievable by diet.  While new, inexpensive measures of vitamin A status are needed, serum retinol remains an interpretable, valid  and comparable indicator for population use.  VAS can be curtailed once fewer than 10% of children
(with 95% confidence) are vitamin-A-deficient, and evidence supports improved dietary intake of vitamin A
in target populations.
