 Interpretación del percentil de peso para la estatura

 
Percentil <5: Peso bajo
Percentil >=5 y <85: Peso saludable
Percentil >=85 y <95: En riesgo de sobrepeso
Percentil >=95: Sobrepeso

 
 

 
Notas
  • Estos estándares de peso para la estatura están disponibles como alternativa al IMC para la evaluación de la sobrenutrición o la desnutrición en niños de edades comprendidas entre los dos y los cinco años. Sin embargo, los profesionales de la salud deben considerar el uso de gráficos del IMC para la edad con el fin de ser coherentes con las recomendaciones actuales.
  • Esta calculadora utiliza la estatura medida en bipedestación para niños de edades comprendidas ente los dos y los cinco años, y no es válido para la longitud en decúbito.
  • En los extremos (percentil >97.º o percentil <3.º), las diferencias pequeñas en los percentiles representan diferencias clínicamente importantes. En estos extremos, el puntaje Z es un reflejo más preciso de cuán lejos se desvía la medición de la media y es una herramienta útil para hacer un seguimiento de los cambios.
  • Los datos de LMS que usa esta calculadora se muestran en la tabla de datos a continuación.
  • Para todas las tablas de LMS, la fila en la tabla correspondiente al valor específico del paciente se encuentra en la primera columna de la tabla; se recuperan los valores a utilizar para L (la potencia de Box-Cox), M (la mediana) y S (el coeficiente de variación generalizado) en la ecuación del puntaje Z.
  • Los puntajes Z se pueden usar para hacer una búsqueda de la tabla para el percentil correspondiente en los percentiles de la tabla normal para la tabla de puntaje Z (más abajo). Los números en el lado izquierdo (eje Y) de la tabla representan el primer número y el primer número decimal del puntaje Z, mientras que los números en la parte superior (eje X) de la tabla representan el segundo decimal del puntaje Z.

 
Ecuaciones utilizadas
 
PuntuaciónZ = ((Peso/M)L - 1) / (L * S)
Percentil = Zparapercentil(PuntuaciónZ)
