Obesity. • It´sanabnormalorexcessivefataccumulation in adiposetissue, totheextentthathealthmaybeimpaired. • The WHO recommends the use of Body Mass Index (BMI); it provides the most useful, albeit crude, population-level measure of obesity. • BMI iswellcorralatedto: • relativeadiposity, • fatmass, and • cardiovascular riskfactors in chidren and adults.

  4. Obesity. Causes Consequences Psychosocial and economic consequences.  Increase of risk factors for chronical diseases. Increase on morbidity.  Increase on mortality. • Lowphysicalactivity. • Consumption of foods rich in fat and sugars. • Consumption of high-density, low-costfoods. • Expression of the “thrifty gene” and chronicundernutrition.

  7. Objective. • Determine the effectiveness of a nutrition education intervention on the prevention and control of overweight and obesity.

  8. Methods • Non-randomized, controlled community intervention study. • 529 school children ( 5-12 yo) from four elementary schools in Villa El Salvador Lima –Peru. • Intervention: Educative intervention in nutrition and health. • Outcome: • Body Mass Index (BMI Z-score) • Proportion of overweight and obesity after intervention. • Analysis: We analyzed the mean differences of this index, using T-test.

  21. Results.

  22. Conclusions. • The Nutritional intervention is effective in preventing and controlling overweight and obesity in the study period. • Growth was similar in each group. • A multi institutional partnership and commitment for educational intervention could be a community approach alternative to prevent and control overweight and obesity in schoolchildren from urban-marginal districts of major cities.

  23. Limitations. • It was not possible to randomize because the kind of the study (Community intervention). • We could not intervene in school kiosk. • The study only reflects a periurban area of Lima city. • We could not know the educative level of parents. • We do not know the sustainability of the intervention yet.

  24. Recommendations. • The "Health promotion team" must perform interventions with a managerial epidemiology approach. • Obtain the commitment from all involved. • A shared goal must be the foundation of this intervention between community; health and education sectors.
