The coexistence of multiple micronutrient deficiencies are increasingly recognized as a pervasive public health problem in developing countries. These deficiencies have a significant negative impact on people’s health. In Mexico, a high prevalence of subclinical vitamin A deficiency, as well as iron and zinc deficiency, have been reported. The latter has been particularly deleterious for Mexican children. Objective . To evaluate the biochemical status of vitamin A, zinc and anemia in school children participating in the school breakfast program in northwest Mexico. Subjects and Methods . Two hundred and eighteen children were clinically evaluated. We conducted a cross sectional study and were series of measurements of the levels of serum retinol, serum zinc and hemoglobin. Results . 37% of children had low levels of serum retinol; as 35% had vitamin A deficiency (DVA,>0.35‐<0.7µmol/L), and 2% presented severe deficiency (<0.35µmol/L). However, zinc deficiency was not found. Anemia was detected (Hb <11.5g/dL) in 7% of children. Conclusions. Vitamin A deficiency and anemia is a public health problem in northwest Mexico.
