Crecimiento físico en niños de 6 a 12 años de media altura de Arequipa - Perú (2320msnm). [Physical growth in children from 6 to 12 years of mediumaltitude of Arequipa - Peru (2320msnm)].

Resumen

El objetivo del presente estudio fue comparar las características del crecimiento físico de niños de 6-12 añosde media altitud, en función a la NCHS y otros estudios, para lo cual, se evaluó el peso corporal (kg), la estatura (cm), el pliegue tricipital (mm) y la circunferencia del brazo (cm) y para el análisis de los resultados se utilizó la estadística descriptiva de media aritmética y desviación estándar y para comparar entre ambos sexos se utilizó la prueba t de student y la prueba de especificidad de Tukey p(menor que 0,001) y para la comparación inter-clase se utilizó ANOVA para muestras independientes (one-way) y la prueba de especificidad de Tukey con una probabilidad de (p menor que 0.001). Finalmente, los resultados presentan mayor peso corporal que la referencia, no siendo así en la estatura donde los niños presentan ligeramente menor estatura y las niñas valores similares a la referencia, excepto a los 6 y 7 años donde la estatura es mayor. A su vez, las características evaluadas, sugieren que el rango de variación de las variables medidas son típicos de las poblaciones de elevadas altitudes.

Palabras clave: Crecimiento físico; niños; altitud.

Abstract

The objective of the present study was to compare the characteristics of the physical growth of 6-12 year-old children of half altitude, in function to NCHS and other studies, for that which, it was evaluated the corporal (kg) weight, the stature (cm), the skinfold tricipital (mm) and the circumference of the arm (cm) and for the analysis of the results it was used the descriptive statistic of half arithmetic and standard deviation and tocompare sexes between both the test it was used student t and the test of specificity of Tukey p (menor que 0,001) and for the comparison inter-class ANOVA was used for independent (one-way) samples and the test of specificity of Tukey with a probability of (p menor que 0.001). Finally, the results present body mass was bigger that the reference, not being this way in the stature where the children present lightly smaller and the girls similar values to the reference, except to the 6 and 7 years where the was bigger. In turn, the evaluated characteristics, they suggest that the range of variation of the variables measures is typical of the populations of high altitudes.

Key words: Physical growth; children; medium altitude.
