VITAMIN A DEFICIENCY

Condition: Vitamin A deficiency (VAD) is an issue in over half of all countries, especially countries in Southeast Asia and Africa. Pregnant women and children are primarily affected. The condition causes blindness and in many instances, death. Other results of Vitamin A deficiency include itchy dry skin, dry hair and a decreased resistance to infections.
Causes: Obviously, a lack of Vitamin A in one's diet is the primary cause of Vitamin A deficiency. The micronutrient is found in high quantities in foods that come from animals (liver, eggs, dairy products) and in many fresh fruits and vegetables. In many parts of the world, due to poverty or environmental issues, people have limited access to food at all, much less Vitamin A rich foods.
Effects: One of the tell-tale signs of Vitamin A deficiency is night blindness. This is because Vitamin A aides in the production of rhodopsin, an eye pigment responsible for seeing in low light
situations. If left untreated, Vitamin A deficiency can progress to complete blindness. In addition, in both children and pregnant women, Vitamin A deficiency increases susceptibility to infections and the body's ability to fight them. Therefore, people affected by this condition have very high mortality rates. In fact, it is estimated that up to 500,000 children go blind each year due to Vitamin A deficiency, and over half of those children die within a year of losing their sight.
Treatment: In order to be effective, there have to be both long and short term treatments for Vitamin A deficiency. First, for people already affected, Vitamin A supplements are necessary twice per year. Each dose costs about $0.02. Next, food fortification (adding Vitamin A to certain foods) has proved very effective. Finally, promoting dietary diversification is important. Encouraging people in rural areas to grow their own Vitamin A rich food is a great way to prevent Vitamin A deficiency in the long run. Many global organizations have
launched efforts against the condition and it is hoped to be eliminated by 2010.
