          Abstract

          O presente artigo apresenta uma revisão sobre o processo de maturação na criança em geral e discute dados em amostras brasileiras. Dados referentes às características sexuais secundárias, para ambos os sexos, são comparados aos de outras populações. A mediana de idade de menarca em meninas brasileiras, obtida pela Pesquisa Nacional de Saúde e Nutrição (Inan, 1990), está em torno de 13,2 anos. Os dados de idade de menarca em atletas brasileiras apontam para uma menarca mais tardia do que na população não-atlética. A idade de início de desenvolvimento de mamas, genitais e pêlos pubianos em crianças brasileiras difere pouco em relação a outras populações latino-americanas e européias. Quanto à maturação sexual e às mudanças na composição corporal, vários estudos brasileiros, em concordância com dados internacionais, mostram que a menarca é um marco importante no aumento dos depósitos de gordura nas meninas. Já nos meninos, parece não haver um aumento expressivo nas dobras cutâneas durante o processo de maturação. É evidente a falta de estudos sobre crescimento, desenvolvimento e maturação do adolescente em várias regiões do país, principalmente no grupo masculino.

          Translated abstract

          This article presents an overview of the maturation process in children and discusses data from some Brazilian samples. Data related to secondary sexual characteristics in both sexes are compared to other populations. The national median menarcheal age in Brazilian girls obtained by INAN (1990) was 13.2 years. The menarcheal age of Brazilian athletes is higher than the non-athletic population. The developmental age of breast, genitals, and pubic hair in Brazilian children differ little in relation to European or other Latin American populations. Several studies developed in Brazil show that menarche is a landmark for the process of fat accumulation in females. However, in boys during the sexual maturation process, significant changes in the skinfold thickness amount and distribution are not observed. It is evident that there is a lack of studies focusing on growth, development, and maturation of adolescents in several regions of Brazil, particularly male adolescents.

            Validation of a self-administered instrument to assess stage of adolescent development.

            Drawings were made from Tanner's photographs illustrating five stages of development each for male genitalia, testicular size, male pubic hair, female breasts, and female pubic hair. Forty-seven females and forty-eight males aged 12-16 years indicated on questionnaires which stage they were most like, and answered other questions related to their physical development. Afterwards they were examined by physicians who had not seen their answers. Pearson correlation coefficients were 0.6 or above for the physician's observations compared with the adolescents' answers for the drawings, with the exception of testicular size. Answers to questions concerning amount of underarm hair and general development also yielded high correlations.
