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. ## Eligibility - **Minimum age:** 5 Years - **Maximum age:** 11 Years - **Sex:** ALL - **Healthy Volunteers:** Yes ``` Inclusion Criteria: 1. School-aged children of both sexes, 5-11 years old, enrolled in the selected primary schools. 2. Children and parents who sign the written informed consent and assent form. Exclusion Criteria: 1. Children participating in any weight loss program, with or without pharmacological treatment. 2. Children with a rheumatological disease, diabetes, thyroid disorder, or any condition that compromises their nutritional status. ``` ## Arms - **Intervention with the mobile application** (EXPERIMENTAL) — 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. - **Control group** (NO_INTERVENTION) — 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. ## Interventions - **Applícate por tu salud** (BEHAVIORAL) — The educational intervention using the mobile application "Applícate por tu salud" aims to promote, improve, and reinforce families' eating habits, focusing on breakfast and school lunches, in order to prevent overweight and obesity in schoolchildren. Through the application, using push notifications, tips in the form of text messages, infographics, videos, and recipes are sent four times a week, encouraging positive changes in eating habits related to breakfast and school snacks. The information was formatted as follows: no more than 30 words, suggesting activities that families could implement at home. Eighty-four messages were generated for breakfast and 104 messages for school snacks, including detailed information on planning, selecting, and comparing foods, as well as their preparation and consumption. The information was generated by three nutrition experts to standardize the language, and a designer created the infographics, videos, and recipes. ## Primary Outcomes - **BMI Z-score** _(time frame: 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. ## Secondary Outcomes - **Improvement in the quality of food consumed at breakfast** _(time frame: Information on school breakfasts is collected at baseline, 6, 12, 18 and 24 months)_ - **Improvement in the quality of food consumed at school lunch** _(time frame: Information on school lunch is collected at baseline, 6, 12, 18 and 24 months within schools)_ ## Locations (1) - Hospital Infantil de México Federico Gómez, Mexico City, Mexico City, Mexico ## Recent Field Changes (last 30 days) - `status.overallStatus` — added _(2026-05-12)_ - `status.primaryCompletionDate` — added _(2026-05-12)_ - `status.completionDate` — added _(2026-05-12)_ - `status.lastUpdatePostDate` — added _(2026-05-12)_ - `design.phases` — added _(2026-05-12)_ - `design.enrollmentCount` — added _(2026-05-12)_ - `eligibility.criteria` — added _(2026-05-12)_ - `eligibility.minAge` — added _(2026-05-12)_ - `eligibility.maxAge` — added _(2026-05-12)_ - `eligibility.sex` — added _(2026-05-12)_ - `outcomes.primary` — added _(2026-05-12)_ - `outcomes.secondary` — added _(2026-05-12)_ - `armsInterventions.arms` — added _(2026-05-12)_ - `armsInterventions.interventions` — added _(2026-05-12)_ - `sponsor.lead` — added _(2026-05-12)_ - `sponsor.collaborators` — added _(2026-05-12)_ - `results.hasResults` — added _(2026-05-12)_ - `locations.hospital infantil de méxico federico gómez|mexico city|mexico city|mexico` — added _(2026-05-12)_ --- *Canonical: https://parkinsonspathways.com/agent/trials/NCT07376252.md* *Source data (authoritative): https://clinicaltrials.gov/study/NCT07376252* *This page is a raw mirror with no AI summary, no editorial enrichment, and no Parkinson's-specific filtering.*
