Resumo: The aim of the present study was to characterize bone mineral density (BMD) and content (BMC) in Brazilian adolescent girls according to age and pubertal stage. A total of 329 girls ranging in age from 10 to 20 years participated in this study. Body weight, height, body mass index, pubertal stage, race, daily calcium intake, and time spent per week performing moderate to vigorous-intensity physical activity (MVPA) were evaluated. Lumbar spine and femoral neck BMD and BMC were assessed by dual-energy x-ray absorptiometry. One-way ANOVA with Tukey post-hoc test was used to identify differences in bone mass between ages and pubertal stages (p≤0.05). The daily calcium intake reported by the adolescents was inadequate, corresponding to only 26-47% of the recommended allowance (1,300 mg/day). On the other hand, weekly MVPA was higher than that recommended for adolescents. Significant differences in BMD and BMC were observed for girls aged 10-14 years. In addition, lumbar spine and femoral neck BMD was 58 and 31% higher in postpubertal girls, respectively, when compared to prepubertal adolescents.

A amostra desse estudo foi composta por 329 meninas com idades entre 10 e 20 anos. Foram avaliados o peso corporal, estatura, índice de massa corporal, estágio de maturação sexual, a raça, o consumo diário de cálcio e o tempo dispendido em atividades físicas de intensidades moderada a vigorosa por semana (AFMV). A densidade e o conteúdo mineral ósseo da coluna lombar e do colo do fêmur foram avaliados pela densitometria óssea. As diferenças da DMO e do CMO, de acordo com a idade e a maturação sexual, foram avaliadas por uma análise de variânciaOne-way ANOVA com o teste post-hoc de Tukey (p≤0,05). O consumo diário de cálcio reportado pelas adolescentes é inadequado, pois representa uma variação de 26 a 47% do que é recomendado. Por outro lado, o tempo dispendido em AFMV, por semana, foi muito superior ao mínimo recomendado, em todas as idades. Ocorreram diferenças significativas tanto na DMO quanto no CMO das adolescentes no período dos 10 e 14 anos de idade. Além disso, os valores de DMO da coluna lombar e do colo do fêmur das adolescentes pós-púberes foram 58% e 31% maiores,respectivamente, quando comparados com os seus correspondentes nas adolescentes pré-púberes.Universidade Federal de Santa Catarina.
