“…Nevertheless, it is unquestionable the increase on prevalence of obesity in Brazilian adolescents, overcoming nutritional deficiencies [2][3][4][5]17,18 . Brazilian studies confirm higher prevalence of overweight and fat accumulation around the waist in wealthier individuals (about twice more), unlike findings in developed countries, where the opposite is verified, even among children and adolescents 5,[18][19][20][21] . It is worth mentioning that almost one third of these individuals showed bad distribution of body fat (a risk for metabolic diseases), with prevalence of fat accumulation around the waist almost ¼ more than overweight (considering BMI percentile > 85º).…”

Objective: To estimate prevalence and identify factors associated with the nutritional status of individuals aged 8 to 17 years old in schools located at 3 administrative regions in the city of Vitória, Brazil. Methods: The nutritional status of 400 students was assessed based on a cross-sectional study. Association between overweight and fat accumulation around waist was tested considering the variables: sexual maturaten stage, income level, number of siblings, maternal Body Mass Index (BMI) and physical activity. Individuals considered stunting had height-for-age < -2 Z-scores of median value for the reference population; wasting, those with BMI < 5 th percentile; overweight, those with BMI e" 85th percentile. Waist circumference was measured under the following parameter: percentile e" 90 of the British population. Results: Prevalence was 4.0% stunting, 4.8% wasting, 21.3% overweight and 27.3% fat accumulation around the waist.

“…Oliveira & Veiga 37 também observaram um maior aumento de excesso de peso nas adolescentes nos estágios finais da maturação sexual, estando relacionado às modificações do tecido adiposo, que apresentam aumento gradual da gordura corporal durante toda a adolescência, ocorrendo o inverso no sexo masculino, no qual há uma perda da gordura corporal em detrimento de um maior estoque de massa muscular.…”

Este estudo objetivou estimar a prevalência de excesso de peso e obesidade abdominal em escolares segundo antropometria e maturação sexual. Foi um estudo transversal, incluindo 1.405 escolares de 10-14 anos, de ambos os sexos, residentes no Recife, Pernambuco, Brasil, em 2007. Foi avaliado o índice de massa corporal (IMC), a circunferência da cintura (CC) e razão da cintura-estatura (RCEst). A maturação sexual foi auto-avaliada, definindo-se como precoce quando o escolar apresentava idade cronológica inferior à mediana de idade para o referido estágio. A prevalência de excesso de peso foi de 20,4% (IC95%: 18,3-22,6) e a de obesidade abdominal foi de 14,9% (IC95%: 13,1-16,9) para CC e 12,6% (IC95%: 10,9-14,4) para RCE. O IMC, a CC e a RCEst apresentaram uma forte correlação positiva (rho ≅ 0,8; p < 0,001). A prevalência de excesso de peso e de obesidade abdominal foi maior (p < 0,05) nos estágios finais de maturação sexual em ambos os sexos. A alta prevalência de excesso de peso requer medidas urgentes de prevenção e controle desse distúrbio, sendo recomendada a inclusão da maturação sexual na avaliação do estado nutricional.

“…For some authors, the prevalence of overweight in the population groups seems to be one of the factors contributing to early menache 5 . In a cross-sectional study conducted by Oliveira and Veiga 21 , which analyzed 502 adolescents, both sexes, from 11 to 15.9 years, attending a public school in the municipality of Rio de Janeiro, the lowest age at menarche was registered among obese girls, when compared to non-obese. This fact may be associated to the weight gain and fat in schoolchildren from that municipality.…”

-The objective of this study was to verify the secular trends of sexual maturation of students between 11 and 15 years old, during a period of 10 and 20 years. The sample was composed by 1,002 students aged between 11 and 15 years; 536 boys (12.6±1.3 years old) and 466 girls (12.5±1.2 years old) who took part in the Ilhabela Mixed-Longitudinal Project on Growth, Development, and Physical Fitness. The students' assessment period occurred in 1990/91 (initial), 2000/01 (10 years later), and 2009/10 (20 years later). Sexual maturation was analyzed according to the self-assessment method and age at menarche (month and year) was collected retrospectively. The statistical analysis used was: one-way ANOVA, and Tukey's post-hoc test. The level of significance was p<0.01. The onset of menarche in the initial analysis was at: 12.5±1.2 years old; in the 2000/01 group: 12.3±1.0 years old (Δ=-1.6%), and in the 2009/10 group: 12.2±1.0 years old (Δ=-2.4%). Although there was a tendency towards reduction in age at menarche along the periods investigated, differences were not significant. There were significant differences only in genitals (G4), and pubic hair (P3) in boys after 10 and 20 years. In the same period, it did not occur any significant difference in maturational stages for girls. In conclusion, there was no secular trend of secondary sexual characteristics in boys (genital and pubic hair) and girls (breast and pubic hair) and in age at menarche over 10 and 20 years. 5±1,2 anos; no grupo 10 anos: 12,3±1,0 (Δ= -1,6%); e no grupo 20 anos: 12,2±1,0 anos (Δ= -2,4%
