“…The mean weight and height of the sample are similar to those reported in a study of students from five Brazilian regions 15 . However, comparison with regional studies showed slightly higher values up to 14 years of age when compared to adolescents from the northeastern region 16 and similar values compared to students from the southern region 17,18 .…”

-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.

Resumo -O presente estudo teve como objetivo caracterizar o conteúdo mineral ósseo (CMO) e a densidade mineral óssea (DMO) de adolescentes do sexo feminino de acordo com a faixa etária e o estágio de maturação sexual. 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

Introduction: Just a few studies have evaluated physical traits, lifestyle and bone mineral density (BMD) acquisition in Brazilian female adolescents. Objective: To identify physical traits and lifestyle factors related to BMD in Brazilian female adolescents. Methods: 329 healthy adolescent girls aged between 10 and 20 years participated in this study. The physical characteristics evaluated were: body weight, stature, body mass index, pubertal stage, self-declared ethnicity and skin color. Concerning lifestyle, the following factors were evaluated: socioeconomic status (SES), physical activity level (PAL) and daily calcium intake. Additionally, total body, lumbar spine and femoral neck bone mineral density (BMD) was assessed by bone densitometry. Pearson's coefficient of correlation (r) and stepwise regression analysis were employed to check dependent and independent variables correlation (p ≤ 0.05). Results: Total body, lumbar spine and femoral neck BMD increase as body weight, height, BMI, age and pubertal stage increase (r ≥ 0.43; p<0.01). On the other hand, only SES (r = 0.14; p<0.05) and PAL (r = 0.12; p<0.05) were correlated. After stepwise regression, body weight, pubertal stage, age, height, calcium intake, SES, and PAL explained around 48-68% for BMD variation in female adolescents. Conclusion: The results suggest body weight, age and pubertal stage should be used as control variables for BMD variations in female adolescents. Furthermore, SES, PAL and daily calcium intake were less important than physical traits for BMD during adolescence.

“…In this context, there has long been an emphasis on the need to conduct studies of physical growth indicators in underdeveloped and developing countries 7 . Given the importance of this topic and its contribution to measurement of population-wide living conditions, it has prompted substantial interest among Brazilian researchers in the field [8][9][10][11] . However, with few exceptions 12,13 , there has been very little research on indicators of physical growth among children and adolescents living in the less socioeconomically and culturally developed regions of Brazil.…”

-The study analyzed physical growth and nutritional status in a representative sample of schoolchildren from the Jequitinhonha Valley region, Minas Gerais, Brazil. A total of 5100 subjects (2730 girls and 2370 boys) aged 6 to 18 years were included in the study. Nutritional status of the under-10 group was assessed by z < -2 for weight-for-height and height-for-age (undernutrition) and by z > +2 for weight-for-height (overweight). For children over 10, the 5 th and 85 th percentiles of weight for age were used to assess underweight and overweight respectively, according to World Health Organization recommendations. Prevalence rates of overweight and obesity according to the International Obesity Task Force criteria were also calculated. The data showed a prevalence of undernutrition below the expected level for the reference population (girls, 1.2%; boys, 3.9%). The prevalence of overweight was approximately 13% for girls and 6% for boys, and obesity was 2% for both sexes. In short, the results indicated a low prevalence of undernutrition and a high prevalence of overnutrition. This shows an urgent need for implementation of educational intervention programs geared to the improvement of physical activity and appropriate dietary habits in this population. Key words: Adolescents; Anthropometry; Children; Obesity; Overweight; Undernutrition.

O estado nutricional dos escolares menores de 10 anos de idade foi identificado pelos escores z < -2 (desnutrição) para os índices massa corporal para estatura e estatura para idade, e pelos escores z > +2 para o índice massa corporal para estatura (sobrepeso
