title: [Results of a community-based life style intervention program for children].
abstract: OBJECTIVE
  Describe the three-year results of a program designed for the adoption of a healthy life style in primary school students on the body mass index (BMI) and the consumption of food.
  
  
  METHODS
  Community randomized and controlled trial. Two communities in the State of Mexico with similar socio-demographic characteristics were randomized to implement the intervention (n=816) or serve as a control (n=408). The intervention was carried out in primary schools and it consisted of education on healthy habits, modification of distributed food and physical activity. The primary outcome was the change in BMI.
  
  
  RESULTS
  After three years, intervention resulted in a lower increase of BMI (1.6 vs. 1.9 Kg/m², p< 0.01) and a decreased consumption of total calories, bread, fat and sugar consumption in the schools.
  
  
  CONCLUSIONS
  School programs are useful to address childhood obesity, but its benefits are not immediate.
