To associate the nutritional status of elementary schoolchildren with their gender, age group, and economic status based on a cross-sectional study carried out at public schools in the municipality of Cruzeiro do Oeste, Southern Brazil.
The study was performed in 2010 including 939 schoolchildren aged six to ten years-old. The economical status of the families was classified based on a socioeconomic ranking questionnaire (Brazilian Association of Survey Companies), and the body mass index was calculated. Data were analyzed by descriptive statistics, and differences between independent groups were verified by Mann-Whitney and Kruskal-Wallis tests, while possible associations were verified by the chi-square test, being significant p<0.05.
The prevalence of obesity in the sample was 8.0%, and overweight, 16.4%. No association was found between the socioeconomic and nutritional status or between the nutritional status and gender.
A high prevalence of overweight and obesity was found in this study, indicating that children of both genders are affected regardless of their economical status and age.

    ABSTRACT: The industrialized countries around the world are experiencing an epidemic of childhood obesity. The level of fatness of a child at which morbidity increases acutely and/or later in life is determined on an individual basis. Overall, however, childhood obesity substantially increases the risk of subsequent morbidity whether or not obesity persists into adulthood. The genetic basis of childhood obesity has been elucidated to some extent through the discovery of leptin, the ob gene product, and the increasing knowledge of the role of neuropeptides such as pro-opiomelanocortin, neuropeptide Y and the melanocyte-concentrating hormone receptors. Environmental and exogenous factors are the main contributors to the development of a high degree of body fatness early in life. Studies involving twins suggest that approximately 50% of the tendency toward obesity is inherited. There are numerous disorders, including a number of endocrine disorders, such as Cushing's syndrome and hypothyroidism, and genetic syndromes, such as Prader-Labhard-Willi syndrome and Bardet-Biedl syndrome, that can present with obesity. A simple diagnostic algorithm allows for differentiation between primary and secondary obesity. Among the most common sequelae of primary childhood obesity are hypertension, dyslipidemia, back pain and psychosocial problems. It is somewhat ironic that the definition of obesity in childhood is not an easy one. Direct measurements of body fat content, such as hydrodensitometry, bioimpedance, or dual-energy X-ray absorptiometry, are useful tools in scientific studies. Body mass index (BMI) is, however, now generally accepted to be a good clinical measure for the definition of obesity in children and adolescents. In preadolescent boys, BMI also relates to muscle mass and should be used for the definition of fat mass with great caution. An increased risk of death from cardiovascular disease in adults has been found in patients whose BMI had been greater than the 75th percentile as adolescents. Therapeutic strategies include psychological and family therapy, modification of lifestyle and behavior, and nutritional education. The role of regular exercise and exercise programs is emphasized, while surgical procedures and drugs used in adult obesity are still not generally recommended for obese children. Obesity is the most common chronic disorder in industrialized countries, and its impact on individual lives as well as on health economics must be recognized by physicians and the public alike. This review aims to increase awareness of the health burden and economic dimension of the epidemic of childhood obesity that is occurring around the globe.

    ABSTRACT: To develop an internationally acceptable definition of child overweight and obesity, specifying the measurement, the reference population, and the age and sex specific cut off points. International survey of six large nationally representative cross sectional growth studies. Brazil, Great Britain, Hong Kong, the Netherlands, Singapore, and the United States. 97 876 males and 94 851 females from birth to 25 years of age. Body mass index (weight/height(2)). For each of the surveys, centile curves were drawn that at age 18 years passed through the widely used cut off points of 25 and 30 kg/m(2) for adult overweight and obesity. The resulting curves were averaged to provide age and sex specific cut off points from 2-18 years. The proposed cut off points, which are less arbitrary and more internationally based than current alternatives, should help to provide internationally comparable prevalence rates of overweight and obesity in children.

    ABSTRACT: Socioeconomic status and its impact on health are in the mainstream of public health thinking. This text discusses two paradigms utilized in assessing socioeconomic status in epidemiologic studies. One paradigm refers to prestige-based measurements and positive differentiation among social strata. This paradigm is characterized by classifications assessing social capital and the access to goods and services. The other paradigm refers to the classification of social deprivation and negative differentiation among social strata. The proposal of State-funded reposition to the mostly deprived social strata is acknowledged as characteristic of this paradigm. The contrast between these paradigms, and their potential interaction and debate are discussed. Fostering reflection on methodological strategies to assess socioeconomic status in epidemiologic studies can contribute to the promotion of health and social justice.
