The objective of this cross-sectional study was to evaluate the effect of Ascaris lumbricoides (A. lumbricoides) and Entamoeba coli (E. coli) on micronutrient status of school-aged children. A total of 284 children (8 y ± 1.6) from a rural area in Mexico participated in the study. A fasting blood sample was collected from all children to determine concentrations of iron, zinc, vitamins A, C, D, and E. Intestinal parasitic infection was determined by a direct smear and Kato Kats technique from a stool sample. Approximately 20% of the population studied was infected with E. coli and 16% with A. lumbricoides. Prevalence of vitamin D deficiency was 28% and 18% had zinc deficiency; no other micronutrient deficiency was observed. Children infected with A. lumbricoides had significantly lower serum concentration of zinc compared with non-infected children (61±11.3 vs 75±10 µg/dL, respectively) (p
