| contents | Iron, zinc and iodide status in Mexican children under 12 years and women 12-49 years of age. A probabilistic national survey Salvador Villalpando Fabiola Mejía Guadalupe Matute Armando García Claudia Ivonne Ramírez Teresa Shamah Juan A. Rivera Salud school Mexico preschoolers age children bearing age Objective. To describe the epidemiology of iron, zinc andiodide deficiencies in a probabilistic sample of Mexican womenand children and explore its association with some dietaryand socio-demographic variables. Material andMethods. We carried out in 1999 an epidemiological descriptionof iron (percent transferrin saturation, PTS, <16%),serum zinc (<65ug/dl) and iodide (<50 ug/l urine) deficienciesin a probabilistic sample of 1,363 Mexican children under12 years and of 731 women of child-bearing age. Serumiron, Total Iron Binding Capacity (TIBC) and zinc were measuredby atomic absorption spectrometry, and urinary iodideby a colorimetric method. Logistic regression models exploreddeterminants for such micromineral deficiencies. Results.Iron deficiency was higher (67%) in infants <2 years ofage. Prevalence declined (34-39%) at school age. The prevalencefor iron deficiency in women was 40%. Zinc deficiencywas higher in infants <2 years of age (34%) than in school-agechildren (19-24%). Prevalence in women was 30%, with norural/urban difference. In women the likelihood of iron deficiencydecreased as SEL improved (p=0.04) and increasedwith the intake of cereals (p=0.01). The likelihood of lowserum zinc levels was greater in women and children of lowsocioeconomic level (SEL) (p<0.02 and p=0.001) iodide deficiencywas negligible in both children and women. Conclusions.The data shows high prevalence of iron deficiencyspeciallyin infants 12 to 24 months of age. It is suggested that in older children and women 12 to 49 years of age that ironbioavailability is low. The prevalence of zinc deficiency wasalso very high.
