Notas
  • Tanto para niñas como para niños, 8,5 cm (3,35 pulgadas) a cada lado de este valor calculado (estatura objetivo) representa el rango probable para su estatura prevista en la adultez (+/- 2 desviaciones estándar con respecto a la estatura objetivo).
  • Esta predicción de la estatura se basa en la estatura media de los padres ajustada de acuerdo al sexo y en los métodos siguientes:
    • Para niñas: restar 13 cm (5,12 pulgadas) de la estatura del padre y promediar con la estatura de la madre.
    • Para niños: sumar 13 cm (5,12 pulgadas) a la estatura de la madre y promediar con la estatura del padre.
    • 13 cm (5,12 pulgadas) es la diferencia promedio en la estatura entre mujeres y hombres.
  • Para calcular la puntuación Z para niñas L = 1,107132561; M = 163,3354491; S = 0,039637105; para niños, L = 1,16863827; M = 176,8414914; S = 0,04036818.
  • 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 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
 
Estatura objetivo para mujeres = ((Estatura del padre - 13) + Estatura de la madre) / 2
Estatura objetivo para varones = ((Estatura de la madre + 13) + Estatura del padre) / 2
Potencial de estatura = Estatura objetivo para el sexo
Puntuación Z = ((Potencial de estatura/M)L - 1) / (L * S)
Percentil de estatura = ZtoPercentile(Puntuación Z)
