Vitamin A Deficiency Definition Vitamin A deficiency exists when the chronic failure to eat sufficient amounts of vitamin A or beta-carotene results in levels of blood-serum vitamin A that are below a defined range. Beta-carotene is a form of pre-vitamin A, which is readily converted to vitamin A in the body. Night blindness is the first symptom of.

Vitamin A deficiency (VAD) or hypovitaminosis A is a lack of vitamin A in blood and tissues. It is common in poorer countries, especially among children and women of reproductive age, but rarely is seen in more developed countries.
Nyctalopia (night blindness) is one of the first signs of VAD. Xerophthalmia, keratomalacia, and complete blindness can also occur since vitamin A. Both vitamin A deficiency and trachoma are important causes of preventable ocular diseases.
We examined 10 children in Mali for clinical signs of trachoma and of xerophthalmia. In five regions, the mean prevalence of trachoma was 393% (95% CI: 374–412). Clinical xerophthalmia was present among 189 % of children (159–225).Cited by: nearly 20% of the population suffers from iodine deficiency, about 25% of children have subclinical vitamin A deficiency, and more than 40% of women are anaemic.
Micronutrient deficiencies also lead to impaired growth and cognitive development, birth defects, cretinism, and blindness, as well as decreased school and work.

Recently prominent nutrition scientists across the world have opposed continuation of vitamin A supplementation (VAS) programmes and recommended gradual phasing out VAS for pre-school children.
