Resumo
O objetivo foi analisar a associação entre maturação sexual relativamente acelerada, excesso de peso e adiposidade central em crianças e adolescentes. Foi realizado um estudo longitudinal com 617 crianças e adolescentes de 8 a 18 anos de idade. Foram realizadas três coletas de dados de peso, estatura, perímetro da cintura. O excesso de peso foi classificado com base nos valores críticos do índice de massa corporal (IMC) para crianças e adolescentes brasileiros. O
estágio de maturação sexual (EMS) foi autoavaliado nas três coletas pelas crianças e adolescentes. Os indivíduos foram distribuídos em quartis de idades segundo EMS e sexo. Foram
comparados os indivíduos com maturação relativamente acelerada com os demais indivíduos. Os dados foram analisados por meio de análises de regressão linear e logística. Foi observada associação negativa entre escore z do IMC e idade de início da maturação sexual em meninos, não sendo observada associação no sexo feminino. A maturação sexual relativamente acelerada associou-se positivamente com excesso de peso e com valores de escore z do IMC. Meninas com maturação relativamente acelerada apresentaram maior adiposidade central. A pesquisa
concluiu que a maturação sexual acelerada associou-se com o excesso de peso e maior incremento no IMC em ambos os sexos evidenciando a importância da identificação do estágio de maturação sexual na avaliação nutricional de crianças e adolescentes.
