Abstract
Antecedentes y objetivo: La dinamometría de la mano es una prueba funcional recomendada en la evaluación nutricional. Suele expresarse en función de la edad pero durante el crecimiento, incluso a la misma edad, varía el tamaño corporal. El objetivo del presente trabajo es aportar referencias de la fuerza de la mano en función de la talla.
Sujetos y método: La muestra consta de 1.798 escolares entre 6 y 15 años. Se midió la talla, el peso y la fuerza de ambas manos. La dinamometría media (DM) se expresó en función de la estatura y se obtuvieron ecuaciones predictivas. La estadística descriptiva, comparativa y el análisis de regresión se efectuaron con el SPSS 21.0
Resultados: Se aportan referencias percentilares para la DM por categorías de talla en rangos de 5 cm. Las fórmulas obtenidas a partir del modelo de regresión (varones: DM = 0,207*peso + 0,621*talla – 71,461; mujeres DM=0,258*peso + 0,394*talla – 43,967) fueron validadas con la mitad de la muestra.
Conclusiones: Las ecuaciones predictivas que se aportan en este trabajo permiten estimar la DM a partir del peso y la estatura con independencia de la edad.
Background and objectives: Hand grip dynamometry is a functional test recommended in the nutritional assessment. Usually it is expressed in terms of age but during growth even at the same age, body size varies. The aim of this study is to provide references of hand strength depending on the height. Subjects and method: The sample consists of 1,798 students between 6 and 15 years. Height, weight and strength of both hands were measured. The mean dynamometry (MD) was expressed in terms of height and predictive equations were obtained. Descriptive statistics, comparative and regression analysis were performed using SPSS 21.0 Results: Percentile references for MD are provided by height categories in ranges of 5 cm. The obtained formulas from the regression model (males : MD=0.207*weight+0.621*height71,461; females: MD=0.258*weight+0.394*height-43.967) were validated in half of the sample. Conclusions: The predictive equations given in this paper allow estimating MD from weight and height independently of age.
