Body weight and height were measured, venous blood was taken to measure serum Retinol and zinc concentrations. The prevalence of vitamin A deficiency was 21.3 percent, zinc deficiency was 75 percent. In boys, girls, and both sexes, there were no significant differences on serum Retinol, zinc concentrations, prevalence of Vitamin A, zinc deficiencies between underweight and normal children (P 0.05).
