Brief summary: Obesity prevention programs in schools are essential to promoting healthy lifestyles. There are programs with positive effects on obesity parameters, but only a few of them have didactic material for its dissemination. In United States they have effective programs (with materials for their implementation) and some are already being implemented in different schools. In Mexico our study group has developed a program called "Planet Nutrition" that includes a manual.The main aim of this study is to evaluate the efficacy of the program "Planet Nutrition"-a nutrition education and behaviour change program- on BMI Z score in school children compared to a control group at 9 weeks. This pilot stud is a randomized controlled trial. The study will be conducted with 41 participants. The primary outcome was the change in the BMI Z score from baseline to 9 weeks. Secondary outcomes were the changes from baseline to 9 weeks in body fat percentage, waist circumference, systolic and diastolic blood pressure, consumption of healthy and unhealthy food, physical activity and sedentary lifestyle, cardiorespiratory capacity and nutrition knowledge. Additionally BMI Z score will be measured at 23 weeks, after the summer vacations. Considering evidence that this period could have a negative impact on children´s weight.

Detailed description: Fifth grade students from a public elementary school in Hermosillo, Sonora, Mexico were invited to participate in the program. The nutritionist team of the study made the request face to face in the classrooms. A printed invitation was delivered to be given to schoolchildren parents, in addition to the informed consent and assent along with a data questionnaire. To be included children must be in fifth grade from the chosen school and be between 9 to 12 years old. The exclusion criteria were, having or develop a medical condition, taking medication or having an intervention that affects body weight, having a condition that prevents physical activity (cardiovascular, respiratory, muscular, osteoarticular, etc.) at baseline or during the study, and withdrawal of the consent informed
