| description | Monitoring physical growth during adolescence provides an important indicator of health status and also makes it possible to identify individuals’ maturity stages. The objectives of this study were to: a) describe the progression of the heights and the body mass of girls and boys from 10 to 14 years of age and the differences between the sexes, and; b) to identify the point and magnitude of peak height growth velocity (PHV) and peak body mass velocity (PMV) for boys and girls. In order to achieve these objectives 70 schoolchildren of both sexes were followed from 10 to 14 years of age. Their height (cm) and body mass (kg) were measured annually from 2001 to 2005. The results demonstrate that up until 12 years of age there are no consistent differences between the sexes, but that at 13 and 14 years of age the boys are taller and heavier than the girls. The PHV and PMV both occurred during the same periods, being from 12 to 13 for boys and from 10 to 11 for the girls. Based on these results we concluded that until the boys reach their PHV, there is no significant difference in physical growth between the sexes and that after this point the boys become taller and heavier than the girls. Furthermore, we concluded that girls reach PHV and PMV around 2 years before the boys. <p><b>Resumo</b>O acompanhamento do crescimento corporal durante a adolescência é um importante indicador de saúde, além de possibilitar a identificação do estado maturacional dos indivíduos. Frente a isso, os objetivos do estudo foram: a) descrever o desenvolvimento da estatura e de massa corporal de meninas e meninos dos 10 aos 14 anos de idade e suas diferenças nesse processo, e; b) identificar o momento e a magnitude do pico de velocidade em altura (PVA) e do pico de velocidade em massa corporal (PVP) de meninos e meninas. Para tanto, foram acompanhados dos 10 aos 14 anos de idade, 70 escolares dos dois sexos. Foram medidas a estatura (cm) e a massa corporal (kg) dos mesmos indivíduos, anualmente, de 2001 a 2005. Os resultados demonstram que até os 12 anos não existem diferenças consistentes entre os sexos, e que aos 13 e 14 anos, os meninos são maiores e mais pesados que as meninas. O PVA e PVP ocorreram no mesmo período, sendo nos meninos dos 12 para os 13 anos, e nas meninas dos 10 para os 11 anos. Frente aos resultados, concluímos que, até o PVA dos meninos, não existem diferenças expressivas no crescimento corporal entre os sexos e que, a partir desse evento, os meninos ficam maiores e mais pesados que as meninas. Além disso, concluímos que o PVA e o PVP ocorrem cerca de dois anos antes nas meninas. |
