Clinical Study Title:
Current status of vitamin A deficiency and the National Vitamin A Control Program in Nepal: results of the 1998 National Micronutrient Status Survey.
|Plain English Summary:|
|This study looked at the prevalence of vitamin A deficiency and the effectiveness of a national vitamin A supplementation outreach program. The supplementation program had a positive effect on the prevalence of vitamin A deficiency in young children. The number of syndromes related to vitamin A deficiency was also reduced. This included night blindness and Bitot's spots. This study however suggested that the prevalence of night blindness is still high among adults, and that vitamin A supplementation should also be recommended for adults as well. The use of a daily vitamin A supplement was also found to be protective against the development of Bitot's spots and night blindness.|
