Indice de sustancia activa (AKS) distribución percentilar en edades pediátricas

Abstract

Se programó conocer la distribución percentilar del índice de sustancia activa (AKS), en niños y niñas de 4 a 9 años para disponer de valores de referencia de este indicador. Se calculó en 3.634 niños eutróficos, con talla normal, sanos, de una comunidad urbana marginal, atendidos en el Centro de Atención Nutricional Infantil Antímano (CANIA) entre enero 1999 y diciembre 2007. Se excluyeron niños prematuros, con inicio de estirón puberal y patologías crónicas definidas o en estudio. El cálculo del peso graso necesario para calcular el índice AKS, se hizo con la fórmula de 2 pliegues de Dugdale y Griffiths para niños menores de 150 cm y niñas de menores de 140 cm. Las variables antropométricas fueron medidas por antropometristas estandarizadas con control de calidad cuatrimestral, aplicando las normas recomendadas Internacionalmente. Se obtuvieron los estadísticos descriptivos del índice y de las variables utilizadas en su cálculo, así como los percentiles 3, 10, 25, 50, 75, 90 y 97 del índice. Se aplicó el test de Kolmogorov-Smirnoff, Anova de una vía, Chi cuadrado, test de Tukey y correlaciones divariadas (p < 0,05). El comportamiento del índice evidenció valores mayores en el sexo masculino decrecientes con la edad tanto en los varones como en las hembras, variando la mediana de 1,28 a 1,04 en el sexo masculino y de 1,17 a 0,94 en el femenino. Se encontraron diferencias estadísticamente significativas para cada año de edad y sexo. Se dispone de valores de distribución percentilar del índice AKS para la evaluación nutricional en edades pediátricas, debiéndose validar su efectividad.
