A total of 5,883 students, including children (6 to 11 years) and adolescents (12 to 17 years), from public schools participated in the study. Body weight and height were measured and the body mass index was calculated for subsequent classification of nutritional status. The t-test was used for comparison between genders and the chi-square test and Poisson regression were used to evaluate the association between EBW, gender, and age. Data were analyzed with the SPSS 11.0 program at a level of significance of p < 0.05. The prevalence of EBW was 19.3% among children and 17.4% among adolescents. EBW was significantly associated with gender and age among children. In addition, the prevalence of EBW was higher among girls (PR = 1.81, 95% CI 1.49 to 2.21) than among boys. Adolescent girl...

The obesity is not a recent phenomenon, 2-3 however its prevalence had never reached epidemic proportions as nowadays . In this sense, it seems to be an ascension tendency in the prevalences of weight excess (overweight and obesity) either in the developed countries, or in those in development. It was observed in Italy, a prevalence of excessive corporal weight among 4 5 children from 3 to 17,5 years around 13,25% , but in Califórnia that prevalence arrives to 22,45% in children with ages between 6 and 13 years. In Brazil the situation is not very different. Studies accomplished in different Brazilian areas detected the following 6 prevalences of excess of corporal weight: Feira de Santana BA, 6,85% (five to nine years old) ; Rio de Janeiro, 11,72% (four to ...

The sample consisted of 122 adolescents (62 females) aged between 12 and 17 years. ASAQ was developed and validated for adolescents in Aus- tralia (Hardy et al, 2007), and for its use in Brazil a transcultural adaptation to Portuguese was done, followed by an assessment of ASAQ's contents by experts. Then, ASAQ was administered within schools, on a typical school day, followed by a retest administration four days later. Total sedentary time was calculated for weekdays and weekends. Intra-class correlation coefficient (ICC) and confidence interval (CI95%) were calculated for both sexes. QASA (acronym for ASAQ Portuguese version) has 13 questions divided into five categories: screen recreation, educational, transportation, cultural activities, and social activities. I...

The aim of the study is to investigate the evidences presented in the literature about the role of the macro and micro environments in the obesity epidemic's actual context. For doing this review, published articles from 1989 to 2008 were studied, using electronic databases, national and international publications, which ones were talking about the following themes: overweight and obesity, and inter-relation between the macro and micro environment and childhood obesity prevalence. Confronting the evidences, to investigate the obesity it's necessary to go beyond the simple detection of prevalences. It's necessary to identify which are the principal factors that affect the obese subjects and propose some intervention models, especially in children and young people, before 10 years of age.
