In this research was determined the effect of supplementation of vitamin A and Zinc as a program of nutritional intervention during 80 days of treatment, selected four groups of children between 7 and 12 years of age, students of the Bolivarian School Catatumbo. The first group was provided with Vitamin A + Zinc sulfate; The second one only with vitamin A; the third group with sulfate Zinc only, and the fourth control group the treatment was before and after clinical assessment, anthropometric, biochemical and dietary. Were collected 5 mL of peripheral blood for the determination of serum retinol by high pressure liquid chromatography (HPLC), and flame atomic absorption spectrometry for serum Zinc. Finding increased levels of serum retinol subsequent supplementation in the first group, an average before supplementation of 33.45 ± 9.28 mg / dl, and 35.07 ± 5.92 mg / dl after supplementation, and the second group with mean values of 12.03 ± 4.73 mg / dl before supplementation, and 12.43 ± 4.86 mg / dl for subsequent supplementation. Were found below the cutoff (<0,72 mg / dl). These results values decreased their beginnings in the first and second group, except at the third. It is recommended to implement policies that include nutrition intervention, nutrition education component and promoting increased consumption of food source Zinc and animal protein source.
