Abstract:
Introduction:Introduction: adolescents' health and nutritional status is demonstrated in the quality of their growth and development. Bone age (BA) is the skeletal development index, which reflects an individual's maturation and is considered as the best expression of human development. Poor nutritional conditions, which extend for long periods, may influence bone development, causing a delay in BA, in relation to chronological age (CA). The aim of this study is evaluating the relation between adolescents' body mass index and bone age. Methods: cross-sectional study carried out with 172 adolescents. The variables evaluated were body mass index (BMI), CA, BA and maturational stage. The BA was determined by taking digital carpal radiographs. Results: the majority of the adolescents presented an adequate nutritional state (73.9%), 42.5% were classified as initial pubertal, followed by 40.6% as in peak height velocity (PHV), with a difference between the sexes (p < 0.001). PHV adolescents presented higher BA averages in both sexes (p = 0.005). There was a correlation between BMI and BA, with a strong correlation for girls in the pre-pubertal stage (r = 0.998; p < 0.05) and moderate correlation for those in PHV (r = 0.421; p < 0.001). By analyzing the relation of the variables to predict adolescents' BA, it was observed that the CA model, maturational stage and BMI explained the variability noted in BA in up to 50.3%. Conclusion: BMI has a relation with BA. It should be noted that BA is influenced by CA, the maturational stage and BMI. Introducción:Introducción: la salud y el estado nutricional de los adolescentes se manifiestan directamente en la calidad de su crecimiento y desarrollo. La edad ósea (EO) es el índice de desarrollo del esqueleto, que refleja la maduración del individuo y es considerada como la mejor expresión del estado del desarrollo humano. Las condiciones nutricionales deficientes que perduran durante largos periodos pueden influir en el desarrollo óseo, provocando retraso en la EO en relación a la edad cronológica (EC). El objetivo del estudio es evaluar la relación entre el índice de masa corpórea y la edad ósea de adolescentes. Métodos: estudio transversal realizado con 172 adolescentes. Las variables evaluadas fueron índice de masa corpórea (IMC), EC, EO y etapa de maduración sexual. La EO se determinó a partir de la realización de radiografías carpales de archivo digital. Resultados: la mayoría de los adolescentes presentaban un adecuado estado nutricional (73,9%), el 42,5% estaban clasificados como púber inicial, seguidos del 40,6% que fueron considerados en el pico de la velocidad de crecimiento (PVC), con diferencias entre sexos (p < 0,001). Los adolescentes en PVC presentaron mayores medias de EO, en ambos sexos (p = 0,005). Se observó una correlación entre IMC y EO, con fuerte correlación para las niñas en la etapa prepúber (r = 0,998; p < 0,05) y correlación moderada para aquellas en el PVC (r = 0,421; p < 0,001). Al analizar la relación de las variables para predecir la EO de los adolescentes, se observó que el modelo con IC, etapa maduracional e IMC fue capaz de explicar hasta en un 50,3% la variabilidad observada en la EO. Conclusión: el IMC presenta relación con la EO. Se resalta que en la EO influyen la EC, la etapa maduracional y el IMC.
