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.

Outcome Measures

Primary Outcomes (1)

• Change in BMI z score

  First, the weight and height of the children were measured with a SECA digital scale and a stadiometer (SECA 213). Then, the BMI z score was obtained using the WHO Anthro Plus software, where the values of weight, age, date of birth and sex were considered.

  Baseline to 9 weeks

Secondary Outcomes (8)

• Change in body fat

  Baseline to 9 weeks

• Change in waist circumference

  Baseline to 9 weeks

• Change in the consumption of healthy and unhealthy food

  Baseline to 9 weeks

• Change in auto-reported physical activity and sedentary activities

Planet Nutrition program BEHAVIORAL

1. \- Nutritional education sessions: The study team previously worked on the development of a handbook called "Planet Nutrition" which contains around 26 topics of nutrition and health. Interns from the Nutritional Sciences Degree of the University of Sonora implemented the sessions. 2 classes of 1 hour were given weekly, adding 18 sessions in total, during regular school hours. The program contemplates the establishment of different objectives. 2. \- Physical activity: The classes were designed and implemented by interns from the Bachelor of Physical Culture and Sport from the University of Sonora along with a teacher from the study team. 3 weekly sessions of 1 hour were provided. The activities were held on the schoolyard court during normal school hours, independent of the physical activity classes of the school. 3. \- Indirect family participation: Six information brochures with different nutrition and health topics were sent to parents.
