WHO Child Growth Standards

Hemos recibido el texto "WHO Child Growth Standards" de parte del Departamento de Nutrición para la Salud y Desarrollo de la Organización Mundial de la Salud.

En este interesante texto se aborda el tema del crecimiento donde la perspectiva metodológica, como la construcción de estándares de velocidad de crecimiento para peso, para talla, circunferencia craneana, definición de centiles, puntaje z, y muchos otros aspectos ilustrados con figuras y curvas de crecimiento.

Reproducimos para nuestros lectores la presentación en inglés que la WHO nos hace llegar junto al texto.

"The WHO Multicentre Growth Reference Study (MGRS) was implemented between 1997 and 2003 to generate new curves for assessing the growth and development of children the world over. The MGRS collected primary growth data and related information from 8440 healthy breastfed infants and young children from diverse ethnic backgrounds and cultural settings (Brazil, Ghana, India, Norway, Oman and USA). A key component of the MGRS design was a longitudinal cohort of children who were examined in a sequence of 21 visits starting at birth and ending at 24 months of age. A principal rationale for the longitudinal component was to allow for the development of growth velocity standards.

The increments on which the velocity standards are based were calculated using the same longitudinal sample of 882 children and statistical approaches as those used in the construction of the attained growth standards.

The velocity standards presented in this report provide a set of tools for monitoring the rapid and changing rate of growth in early childhood and can be used to assess children everywhere, regardless of ethnicity, socioeconomic status and type of feeding".
