Variação temporal no excesso de peso e obesidade em adolescentes de escola privada do Sul do Brasil
Revista Brasileira de Atividade Física & Saúde, 2014
The aim of this study was to evaluate the temporal variation in a 12-year period of the overweight and obesity prevalence in adolescents at a private school from Pelotas-RS and the cross-sectional association with physical activity and TV-viewing. Two cross-sectional studies were carried-out with high school students in 2000 and 2012. Standing height and weight were measured. Overweight and obesity were defined when the z scores of BMI for age were higher than +1 and +2, respectively. Adolescents who reached at least 300 minutes/week of physical activity were considered as active in 2012. TV-viewing ≥ 2 hours/day was considered as high. In 2000, the overweight prevalence was 21.5%, whereas in 2012 increased to 30.7% (p=0.003). Concerning the obesity, the prevalence almost doubled, changing from 5.0% to 9.7% (p=0.001). In the two periods, both overweight and obesity were more prevalent in boys. Between 2000 and 2012, the overweight prevalence increased more in boys (p=0.002), whereas the obesity increased more in girls (p=0.01). Both outcomes increased mainly in adolescents aged 16 years old or more. Physical activity was not associated with both outcomes in 2012. However, TV-viewing ≥ 2 hours/day was associated with more than 10 percentage points in the overweight prevalence. The results showed a large increase in the overweight and obesity in adolescents from this school.

Prevalência de sobrepeso e obesidade em adolescentes da zona sul de São Paulo
ABSTRACT: Obesity is considered to be one of the major public health issues nowadays, as it increases the risk of morbidity for the main chronic diseases. Obese adolescents are more likely to become obese adults than eutrophic individuals of the same age group. The aim of this study was to verify the prevalence of overweight and obesity in high school students from a private school in the city of São Paulo. Six hundred and eleven adolescents of both genders were evaluated, ageing 14 to 18 years old. Participants' weight, stature and body fat were assessed. Analysis revealed that 25,6% of girls and 27,8% of boys were classified as having overweight or being obese according to BMI. However, according to percentage of body fat, 62,1% of girls and 34,6% of boys had excessive adiposity or obesity. We found a high correlation between BMI and percentage of body fat in both groups (girls r= 0,8; boys r= 0,85). Prevalence of overweight and obesity was high and superior in girls, and desp...

Prevalência de sobrepeso e obesidade em escolares da cidade de Santos, SP
Arquivos Brasileiros de Endocrinologia & Metabologia, 2006
O objetivo deste estudo populacional foi verificar as prevalências de sobrepeso e obesidade em escolas públicas e particulares da cidade de Santos, SP. Foram avaliadas crianças de 7 a 10 anos de idade, num total de 10.822 crianças. Para a determinação de sobrepeso e obesidade foram utilizados, respectivamente, os percentis 85 e 95 do IMC por idade propostos pelos Centers for Disease Control and Prevention -CDC (2000). As prevalências totais de sobrepeso e obesidade foram de 15,7% (IC 95%= 15,0% a 16,4%) e 18,0% (17,3% a 18,7%), respectivamente. A prevalência de sobrepeso foi de 13,7% (12,6% a 14,8%) nos meninos e 14,8% (13,7% a 15,9%) nas meninas das escolas públicas. Nas escolas particulares, foi de 17,7% (15,7% a 19,7%) nos meninos e 22,2% (20,0% a 24,4%) nas meninas. A obesidade foi prevalente em 16,9% (15,7% a 18,1%) dos meninos e 14,3% (13,2% a 15,4%) das meninas das escolas públicas. Nas escolas particulares, 29,8% (27,4% a 32,2%) dos meninos e 20,3% (18,2% a 22,4%) das meninas foram diagnosticados como obesos. Concluímos que a prevalência de obesidade é superior à de estudos nacionais e latino-americanos. Escolas privadas apresentaram prevalência de obesidade maior que escolas públicas (p= 0,001).
