    Contribuições das práticas alimentares e inatividade física para o excesso de peso infantil
    (Sociedade de Pediatria de São Paulo, 2008-09-01) Rinaldi, Ana Elisa M.; Pereira, Avany Fernandes; Macedo, Célia Sperandeo; Mota, João Felipe [UNIFESP]; Burini, Roberto Carlos; Universidade Estadual Paulista (UNESP); Universidade Federal do Rio de Janeiro; Universidade Federal de São Paulo (UNIFESP)
    OBJECTIVE: To review the literature in order to show how current feeding and physical activity practices may contribute to childhood overweight. DATA SOURCE: Ovid Journals, Highwire and SciELO, selecting original and review articles from 1997 to 2007, published in English and Portuguese. DATA SYNTHESIS: The periodic assessment of children nutritional status is important to diagnose their current health status and to predict their adult life prognosis. In Brazil, the prevalence of childhood obesity is progressively increasing in all social classes and its frequency varies from five to 18%, according to the region assessed. The association between the health, demographic and behavioral transition and the change in feeding practices can explain the increasing prevalence of childhood overweight. The current food consumption with high fat, sugar and sodium intake and low intake of whole cereals, fruits and vegetables associated to physical inactivity due to the excessive use of computers, electronic games and television may play a role in childhood obesity. This life style can be explained by changing family habits and school environment. CONCLUSIONS: These data suggest considerable influence of environmental factors, mainly nutritional habits and physical inactivity, on the increasing prevalence of childhood overweight.

    Obesity and undernutrition in a very-low-income population in the city of Maceio, northeastern Brazil

    Obesity is the nutritional disorder which has shown the greatest increase in prevalence, even in those countries in which deficiency diseases represent a severe public health problem. The goal of the present study was to analyse the anthropometric profile of a community living in the outskirts of Maceio, capital of Alagoas (northeastern Brazil), and to investigate the hypothesis of a coexistence of undernutrition and obesity in a very low-income population. The survey was conducted on 315 families (1247 individuals). Among the children (aged l10 years), the prevalence of wasting, stunting and wasting plus stunting was 3.8, 8.3 and 8.7 % respectively. Wasting (10.2 %) was the most prevalent form of undernutrition among adolescents; nonetheless, a higher frequency of stunting (11 %) and overweight-obesity (5.5 %) was seen specifically in girls, in agreement with trends found in other studies. Adults exhibited a high prevalence of overweight-obesity (25 %), but stunting was also present (22 %). Of the stunted individuals, 30 % were overweight-obese and 16.3 % were underweight. There were eighty-six families with at least one parent who was underweight (27 %) and 104 families with at least one parent who was overweight (33 %). Underweight and overweight-obesity were both present in ninety-six households (30 %). These results may indicate that better living conditions in urban areas in a population 'adapted' to chronic famine might increase the susceptibility to obesity. Considering the harm caused by the cumulative effect of these two conditions (undernutrition in childhood and obesity in adult life) there is a clear need for new studies to uncover the determinant factors so that preventive measures can be implemented.
