Background. Lifestyles that promote a positive energy balance increase the prevalence of obesity. Due to the magnitude of this problem, community-level strategies are required on how to provide families with useful information to prevent it. Electronic media such as the Internet and mobile health applications are tools that have opened a new audience to send information, they are accessible and powerful, as well as the capacity to reduce associated costs, their access to information is uninterrupted, support , and personalized feedback. There is a need to develop and evaluate mobile health applications to establish consistent and effective methods to produce changes in health behavior in the population.
Aim. To evaluate the impact of a mobile health application in nutrition and physical activity on nutritional status in school children.
Methods. Community essay. Children from 4 primary schools in Mexico City will participate in the educational intervention. The schools were randomly assigned to one of two groups: 1) Apply for your health! group and 2) Control group. The educational intervention through the application will last 12 months and will focus on promoting healthy eating habits and physical activity, empowering parents to change habits. In the second year, the control group will be given access to the mobile application. At baseline, 6, 12, 18 and 24 months, children in both groups will have their nutritional status (anthropometry) and breakfast and school snack habits measured. Statistic analysis. Mixed effects models will be used to evaluate changes in BMI z-score within and between groups.

研究组 & 干预措施
Intervention with the mobile application
The educational intervention was implemented through the mobile application "Applícate por tu salud" (Get Healthy), with the goal of sending information to parents on how to improve eating habits at breakfast and school lunch. To this end, recipes, text messages, and infographics related to these topics were developed.
干预措施: Applícate por tu salud (Behavioral)
Control group
The control group received no educational intervention. Only anthropometric measurements and data collection on diet and physical activity were carried out. However, the results of the anthropometric measurements were given to the parents at different times.
结局指标
主要结局
BMI Z-score
时间窗: Anthropometric evaluations to obtain the BMI Z score are performed at baseline, 6, 12, 18 and 24 months.
The BMI Z-score variable will be assessed continuously. To evaluate the change in the BMI Z-score, the difference between the corresponding measurements at 6, 12, 18, and 24 months versus the baseline measurement will be calculated. A minimum and maximum of -5 to +5 SD will be considered. Likewise, a value closer to zero will be considered the best nutritional condition.
次要结局
- Improvement in the quality of food consumed at breakfast(Information on school breakfasts is collected at baseline, 6, 12, 18 and 24 months)
- Improvement in the quality of food consumed at school lunch(Information on school lunch is collected at baseline, 6, 12, 18 and 24 months within schools)
