Abstract
OBJECTIVE: To describe the current status of micronutrient deficiencies (MD) and anemia in Mexican children. MATERIALS AND METHODS: Serum data from 1 382 pre-school-age chil-dren (1-4 years) and 3 590 school-age children (5-11 years) Ensanut 2018-19 participants were analyzed. Iron deficiency (ID), vitamin B12 deficiency (B12D), vitamin A depletion (VADp), and anemia were identified. Logistic regression models were used to identify associations between socio-demographic characteristics of children and MD. RESULTS: Anemia was present in 28.9 and 19.2% of the children aged 1-4 and 5-11, respectively; in ID 10 and 5.1%; B12D, in 5.1 and 4.8%, and VADp, in 4.7 and 4.3%. 18.5% of the preschool-age children and 13% of the school-age children had at least one MD associated to anemia. CONCLUSIONS: MD and anemia affect the younger children in larger proportion. Fortification and supplementation programs should be reinforced to avoid the long-term consequences of MD.
