Nutritional causes of anemia in Mexican children under 5 years: results from the 2006 National Health and Nutrition Survey Causas nutricionales de anemia en niños menores de 5 años: resultados de la Encuesta Nacional de Salud y Nutrición 2006

Abstract

OBJECTIVE: To describe the frequency and severity of anemia and the nutritional variables associated to hemoglobin levels (Hb) in children OBJETIVO: Describir las causas y severidad de la anemia y los factores nutricionales asociados con hemoglobina en niños anémicos <5 años. MATERIAL Y MÉTODOS: Estudiamos los niveles de hemoglobina y las concentraciones séricas de ferritina, receptores solubles de transferrina, proteína C reactiva (CRP), zinc, hierro, cobre, magnesio, vitamina B12 y folato en 981 niños. Se utilizaron modelos de regresión ordinal y regresiones lineales múltiples para evaluar el riesgo de severidad de anemia y la variabilidad en hemoglobina. RESULTADOS: La prevalencia de anemia fue de 20.6%; el 14 y 6.38% tenían anemia leve y moderada. La anemia se asoció con deficiencia de hierro (DH) en 42.17%; la DH coexistió con deficiencia de folatos y vitamina B12 en 9%. Sólo 2% de la anemia se asoció con deficiencia de folatos o vitamina B12. CRP (coef: 0.17 g/dl) y el tercer tercil de cobre (coef: -0.85 g/dl) se asociaron con anemia sin explicar (p<0.05). CONCLUSIONES: DH es la principal causa de anemia en niños <5 años. Las concentraciones de folato y vitamina B12 se asociaron con anemia. La CRP se asoció con anemia sin explicar. Sin embargo, la deficiencia de vitamina A, que se asocia con anemia, no fue estudiada.
