- 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

- Primary Outcome Measures
Name Time Method Change in BMI z score Baseline to 9 weeks 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.
- Secondary Outcome Measures
Name Time Method Change in the consumption of healthy and unhealthy food Baseline to 9 weeks The questionnaire consists of 12 questions about the consumption of healthy foods (fruits, vegetables, cereals, legumes, animal source food, dairy, etc.) and unhealthy (sugary drinks, salty snacks, sweets, pastries, sausages, etc..). The frequency ranges from never to more than twice a day.
Change in nutrition knowledge Baseline to 9 weeks To assess the learning in the nutritional education sessions, a questionnaire designed by the study team was used. It consisted of 32 questions about nutrition and health. The answers consisted by multiple choice with 4 subsections (A-D) and true or false choices.
Change in systolic and diastolic blood pressure Baseline to 9 weeks A digital sphygmomanometer, model Omron HEM-907, was used. Two measurements were made to obtain an average value of systolic and diastolic blood pressure.
Change in auto-reported physical activity and sedentary activities Baseline to 9 weeks It was measured by a validated questionnarie for schoolchildren which includes nine questions about the frequency and time spent in physical activity and sedentary activities during the week and weekend.
Change in body fat Baseline to 9 weeks A tetrapolar electrical bioimpedance method (BIE) was used to obtain the resistance and reactance values. The measurement was made with the BIE team, RJL Quantum II. To estimate the body fat percentage, a validated equation in Mexican children was used.
Change in waist circumference Baseline to 9 weeks The measurement was taken at the umbilical scar level, with the participant standing and on the upper garment (due to the lack of privacy) using a non-stretch tape measure.
Change in cardiorespiratory capacity Baseline to 9 weeks It was measured by the Course Navette test to estimate the maxium oxygen consumption (Vo2 Max).The participants traveled a distance of 20 meters round trips, at the rhythm of a recording sound. The test is in one minute stages and the speed increases (0.85 km / h to 0.5 km / h). The participants were stopping when they felt tired. The test was carried out by the physical activity team of the study.
Change in BMI Z score 9 weeks to 21 weeks It will be measured returning from summer vacations, following the same method.
