Resumo: | The relationship between anthropometric variables and maturation stages is important for a more detailed monitoring of pubertal development and may provide a suitable tool for clinical diagnosis. The aim of this study was to analyze the predictive contribution of anthropometric variables to pubertal maturation using multivariate discri-minant analysis. A total of 190 boys aged 8 to 18 years, from public and private schools in Natal, Brazil, participated in the study. Thirty-two anthropometric variables were measured and pubertal maturation was evaluated objectively by observing pubic hair development. Measures of central tendency and dispersion, inferential analysis of variance, and multi-variate discriminant analysis were used for statistical analysis. Pubertal advancement was accompanied by significant changes in anthropometric variables (p<0.05). Discriminant analysis identified eight variables with a high predictive capacity of pubertal maturation: age, sitting height, biacromial breadth, acromiale-radiale, trochanterion-tibiale laterale and tibiale laterale bone lengths, and abdominal and forearm girths. The anthropometric variables showed a high correlation with the classification of pubertal maturation, dem-onstrating a high predictive level among them. These findings indicate the possibility of developing a predictive equation for pubertal stages. |

O objetivo do presente estudo foi analisar a contribuição preditiva das variáveis antropométricas sobre a maturação puberal, a partir do método multivariado de análise discriminante. Foram avaliados 190 sujeitos do sexo masculino, entre oito e 18 anos, alunos de escolas públicas e privadas de Natal, Brasil. Trinta e duas variáveis antropométricas foram mensuradas e a avaliação da maturação puberal foi realizada a partir do método objetivo da pilosidade púbica. A estatística foi representada pelos valores de tendência central e seus derivados, e de forma inferencial, pela Análise de Variância e análise discriminante multivariada. O avanço dos estágios puberais foi acompanhado de modificações significativas das variáveis antropométricas (p< 0,05). A análise discriminante identificou oito variáveis com alta ca-pacidade preditiva da maturação puberal, sendo elas a idade, ATC, diâmetro bi-acromial, comprimentos ósseos acrômio-radial, trocânter-tibial e tibial, e perimetrias de abdômen e antebraço. Estas variáveis foram responsáveis por estimar os estágios puberais com índice preditivo de 77,4% de chance de acerto, confirmando a alta relação entre estes parâmetros. As variáveis antropométricas apresentaram uma alta relação com a classificação da maturação puberal, demonstrando um alto nível preditivo entre elas, e confirmando a viabilidade da criação de uma equação preditiva dos estágios puberais.Universidade Federal de Santa Catarina.
