Ascaris lumbricoides (A. Lumbricoides) and Entamoeba coli (E. coli) are two of the most prevalent intestinal parasites in Mexican children. The objective of this study was to determine the association of E. coli and A. lumbricoides infection with energy, macronutrients and food group intake in school age children. A total of 284 children (8 y ± 1.6) from a rural area of Queretaro, Mexico, participated in a cross-sectional study. Anthropometry and body fat (by DXA) were measured. Parents were interviewed to determine dietary intake using both a food frequency questionnaire (FFQ) and three 24-h recalls (24HR). Intestinal parasitic infection was determined by a direct smear and Kato Kats technique from a stool sample. The prevalence of E. coli and A. lumbricoides infection was 20% and 16%, respectively. Children infected with E. coli had a higher intake of energy and fat, and higher consumption of dairy, legumes, meat and cereals than non-infected children (p < 0.05). In contrast, children infected with A. lumbricoides had a significantly lower intake of energy, carbohydrates and fiber, and lower consumption of dairy and meat compared with non-infected children (p < 0.05). In this study, children infected with E. coli had a higher energy, macronutrient, and food group intake while children infected with A. Lumbricoides had lower energy, carbohydrate and fiber intakes. Further studies are needed to clarify the causal relationship.
