Resumen

Background: In Mexico, prevalence of anemia in children <5 years of age (preschool) is high at all socioeconomic levels. We undertook this study to analyze the socioeconomic determinants of the prevalence of anemia in preschool children and to explore the reasons why the prevalence is high, even in wealthier households. Methods: We used the National Survey of Health and Nutrition (ENSANUT) 2012 and calculated logistic regression models, considering as explanatory variables socioeconomic characteristics of children and mothers, among others. Models were estimated for all preschoolers and for each tercil of socioeconomic status. Results: The national prevalence of anemia in preschool children is 23.3%; in the lowest tertile it is 26.4%, whereas in the highest tertile it is 20.2%. Variables related to increased risk of anemia in the highest tertile are male children (OR: 1.24), those <2 years of age (OR: 2.31), stunting (OR: 2.01), and mother as the head of the household (OR: 2.06). Conclusions: Although anemia prevalence is higher at poorer socioeconomic levels, it remains high at all socioeconomic levels. Therefore, a general strategy is required to reduce the rate of childhood anemia rather than only the targeted efforts followed so far. Further research is needed.
