Results from a nationwide probabilistic survey in Mexico Salvador Villalpando Teresa Shamah Claudia Ivonne Ramírez Fabiola Mejía Juan A. Rivera Salud child anemia Mexico infant preschool Objective. To describe the epidemiology and analyze factorsassociated with iron deficiency anemia in a probabilisticsample of the Encuesta Nacional de Nutrición 1999 (ENN-99) [National Nutritional Survey 1999 (NNS-99)]. Materialand Methods. The sample included 8 111 children aged1 to 12 years, and was nationaly representative by rural andurban strata and by four geographical regions. Capillary hemoglobinwas measured using a portable photometer (HemoCue).The analysis of the determining factors of anemiawas performed by odds ratios derived from a logistic regressionmodel and multiple regression models. Results.The prevalence of anemia was 50% in infants <2 years ofage, with no significant differences between urban and ruralstrata or among regions. It varied between 14 and 22% in6-11 year-old children and was higher in the South regionand among the indigenous children. Dietary intake of ironwas 50% of the recommended daily allowance in children<2 years of age, but not in older children. Phytate (»500-800 mg/d) and tannin (»19 mg/d) intakes were very high inchildren over 7 years of age. Hemoglobin was positively associatedwith nutritional status of children (p=0.01), socioeconomicstatus (p range 0.05-0.001), duration of lactationin children under 2 years of age (p=0.1), and iron and calciumintake (p=0.02), but not with folic acid or vitamin B12intake. Hemoglobin was negatively associated with maternaleducation (p=0.01) in older children, but not in thoseunder 2 years of age. Conclusions. We present evidence ofan alarming national epidemic of anemia, particularly marked in children 12 to 24 months of age. The control of anemiashould be considered as an urgent national concern givenits grave consequences on the physical and mental developmentof these children and on their long-term health.The English version of this paper is available too at: http://www.insp.mx/salud/index.html 2003 artículo científico 0036-3634 https://www.redalyc.org/articulo.oa?id=10609805 en http://www.redalyc.org/revista.oa?id=106 Salud Pública de México application/pdf Instituto Nacional de Salud Pública Salud Pública de México (México) Num.Su4 Vol.45 |
