RESUMO
OBJECTIVE: To describe the variety of feeding in households with children under five years by level of food insecurity. MATERIALS AND METHODS: We analyzed data from the database of the National Household Income and Expenditure Survey 2008, using the Mexican Scale for Food Security and constructed variables for "per capita expenditure", "purchase frequency" and "quantity purchased" for 12 food groups, associating them with food insecurity (FI). RESULTS: The prevalence of households classified with food insecurity was 48%. We found a relationship between lower food variety and greater food insecurity, with a possible "substitution effect" of protein sources among households with FI. CONCLUSION: As food insecurity severity increased, the variety of the diet decreased.

Objetivo. Describir la variedad de la alimentación en hogares con niños menores de cinco años por nivel de inseguridad alimentaria. Material y métodos. Se analizó información de la base de datos de la Encuesta Nacional de Ingreso y Gasto en los Hogares (ENIGH) 2008, utilizando la Escala Mexicana para la Seguridad Alimentaria (EMSA) y se construyeron variables de gasto per cápita, frecuencia de compra y cantidad comprada de 12 grupos de alimentos, asociándolas con la inseguridad alimentaria (IA). Resultados. La prevalencia de hogares clasificados en inseguridad alimentaria fue de 48%. Existe una relación entre una menor variedad de alimentos y mayor IA, y un posible efecto de sustitución de fuentes de proteínas en los hogares en IA. Conclusión. Cuanto mayor IA, menor es la variedad de alimentos.
