Assessment of somatic maturation of Venezuelan adolescents

Introduction: beginning of adolescence comprises important physical modifications, which affects growth and changes in body composition, therefore it is important to consider maturation assessment. Objective: to develop a non-invasive method to assess maturity status in Venezuelan adolescents from p...

Objective: to develop a non-invasive method to assess maturity status in Venezuelan adolescents from peak height velocity (PHV) by means of anthropometric variables in a cross-sectional sample. Methods: data comprised 681 Venezuelan adolescents 9 up to 18 years of age. Mirwald equation was applied to derived PHV. Regression analysis was used in order to build a model for Venezuelan sample as well as, ROC curves to assess sensitivity and specificity of anthropometric variables. Results: the predictive equations for both sexes, exhibited a high determination coefficient (< 0.99) and a minimal estimation error (0.06).
