Participatory Intervention to Improve Nutrition and Physical Activity in Schoolchildren From Acatlán de Juárez, Jalisco (Acatlan)

This is a community project carried out jointly by the Technological Institute of Higher Studies of the West (ITESO), the University Center of Tonalá of the University of Guadalajara (CUTonalá) and the University Center of Health Sciences of the University of Guadalajara ( CUCS) with advice from the National Institute of Public Health (INSP), financed by the Tresmontes Lucchetti company and endorsed by the Jalisco Association of Nutritionists, AC (AJANUT). This project follows the provisions of the "National Strategy for the Prevention and Control of Overweight, Obesity and Diabetes" signed by the executive branch of the Federal Government. In particular, this project is inserted within the Public Health Strategy, in the strategic axis of Health Promotion and educational communication (while still having an impact on the axes of Epidemiological Surveillance and Prevention). In addition, it follows the agreement in which the general guidelines for the expenditure and distribution of food and beverages prepared and processed in the schools of the National Educational System were obtained, proposed by the Ministries of Health and Public Education. The aforementioned referrals are intended to protect and improve the health of Mexican children.

Study Overview

• Status: Completed
• Conditions: Sedentary Behavior; Child Obesity; Adipose Tissue
• Intervention / Treatment: Behavioral: Participatory intervention

Detailed Description

The project is a community trial that will last three years, which includes an intervention group and a control group of three schools each. Acatlán de Juárez has a total of 11 elementary schools.

The strategies will be implemented in collaboration with the authorities of the Acatlán de Juárez community, the school authorities, ITESO staff, CUTonalá, CUCS, and AJANUT. Key actors from both the school and community levels will be involved through the study to adapt the strategies socially and culturally to promote community project ownership. An initial study of the viability of the project and the current conditions of food and physical activity in school facilities will be carried out, as well as the perception of the community. The research team will design the contents and materials of the intervention taking into account the opinions and suggestions of the community and the results of the initial study. The schools of the control group will be chosen from the municipality of Villa Corona, Jalisco, which is similar to Acatlán de Juárez.

The strategies proposed for intervention by the research team, which will be agreed with the community, including the following:

• Surveillance in compliance with the regulation of the sale of food in school buildings, according to official guidelines
• Sensitization of children, parents, teachers (especially those in charge of the physical education class) and personnel in charge of the food supply (school cooperative), to improve acceptance and commitment to the regulation of the sale of food
• Training for the preparation of hygienic and healthy food for the personnel in charge of food sale
• Promotion of the consumption of simple water and healthy foods
• Rescue and promotion of the consumption of regional foods
• Reconditioning of the infrastructure for the consumption of simple water, free and healthy food, and the realization of physical activity
• Organization of events and support in the coordination of groups that promote physical activity at the community level
• Optimization of physical education classes at school sites
• Implementation of health promotion and care actions in the school context
• Development of skills in the school community for health care and generation of healthy school environments
• Creation and strengthening of health and nutrition committees in schools, with the participation of directors, teachers and parents to generate necessary and permanent conditions that favor healthy environments

To achieve a greater rapprochement with the population, qualitative instruments will also be implemented before the intervention, such as focus groups and in-depth interviews, which allow the identification of barriers and possible solutions to improve eating habits and promote physical activity in the population. Likewise, during the intermediate and final measurement phases, similar qualitative strategies will be applied to rescue successes and points for improvement of the intervention.

During the implementation of the strategies, meticulous monitoring of the localities will be carried out to identify significant changes that may affect the eating habits and physical activity in either of the two groups (intervention and control).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: General Intervention; The strategies will be implemented in the three intervention elementary schools. The schools were conveniently chosen for the size of the student population. In addition to having a sufficient population, it was important that the authorities of each school site agreed to participate.	Behavioral: Participatory intervention; Surveillance in compliance with the regulation of the sale of food in school buildings, according to official guidelines Training for the preparation of hygienic and healthy food for the personnel in charge of food sale Promotion of the consumption of simple water and healthy foods Reconditioning of the infrastructure for the consumption of simple water, free and healthy food, and the realization of physical activity Organization of events and support in the coordination of groups that promote physical activity at the community level Optimization of physical education classes at school sites Implementation of health promotion and care actions in the school context Development of skills in the school community for health care and generation of healthy school environments Creation and strengthening of health and nutrition committees in schools, with the participation of directors, teachers and parents to generate necessary and permanent conditions that favor healthy environments; Other Names: Physical activity; Healthy diet; Nutrition literacy
EXPERIMENTAL: Subsample intervention; A group will be randomly selected from each school grade from the intervention schools, and within each chosen group 12 children will be randomly selected per group (48 children in total per school).	Behavioral: Participatory intervention; Surveillance in compliance with the regulation of the sale of food in school buildings, according to official guidelines Training for the preparation of hygienic and healthy food for the personnel in charge of food sale Promotion of the consumption of simple water and healthy foods Reconditioning of the infrastructure for the consumption of simple water, free and healthy food, and the realization of physical activity Organization of events and support in the coordination of groups that promote physical activity at the community level Optimization of physical education classes at school sites Implementation of health promotion and care actions in the school context Development of skills in the school community for health care and generation of healthy school environments Creation and strengthening of health and nutrition committees in schools, with the participation of directors, teachers and parents to generate necessary and permanent conditions that favor healthy environments; Other Names: Physical activity; Healthy diet; Nutrition literacy
NO_INTERVENTION: Control; Three primary schools were selected from a close locality (Villa Corona, Jalisco). This was chosen because it is similar in relation to the social, economic, and geographical context to the locality of intervention. The schools were selected for the similarity in the size of the student population of the intervention schools.
