RANDOMIZED
PARALLEL
The study design will be of the factorial type, with 4 group arms:
A) Group 1: control (without any activity); B) Group 2: will receive educational activities in the classroom; C) Group 3: will receive changes in the school environment (nudge strategies); D) Group 4: will receive educational activities and changes in the school environment.
PREVENTION
NONE
Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Nudge
This group will receive changes in the school environment (nudge strategies). Interventions regarding food consumption were based on nudge strategies to led students to eat more fruits and vegetables. To stimulate physical activity, several sports equipment (basketball hoops, volleyball nets, balls, ropes, shuttlecock and a lot of toys) are available for use in the school sports court.
Nudge
School lunchrooms are the central place of modifications regarding food consumption, where the following strategies will be conducted:
1. arrange the fruits served in the school lunch in a prominent position, in containers of bright and contrasting colors to serve them;
2. Create creative names for food served at meals will be created by the students used on displays at canteen tables, posters on the way of the cafeteria and at a menu outside the cafeteria.
To encourage water consumption, footprints that lead to them to water fountains will be painted on the floor. To stimulate physical activity, several sports equipment (basketball hoops, volleyball nets, balls, ropes, shuttlecock and a lot of toys) will be available for use in the school sports court. The courts will be renovated and footsteps painted in order to nudging students to the sports equipment.
Primary prevention
This group will receive educational activities in the classroom. Classroom-based educational activities will be based on an earlier study, called PAPPAS, which was developed in the same city and constituted a school-based intervention with the objective of reducing the consumption of sweetened beverages and biscuits and increase the consumption of fruits, vegetables and beans.
Primary prevention
Classroom-based educational activities based on an earlier study, called PAPPAS, which was developed in the same city and constituted a school-based intervention with the objective of reducing the consumption of sweetened beverages and biscuits and increase the consumption of fruits, vegetables and beans. Activities will be facilitated by trained research assistants. Printed instructions and orientations on the facilitation process will support the assistants' efforts. The activities will require 20 to 30 minutes, and teachers will be encouraged to reiterate the message during their lesson. The goal is to promote ten one-hour sessions of activity for each class.
Primary prevention + nudge
This group will receive educational activities and in the classroomchanges in the school environment (nudge).
Primary prevention + nudge
This group will receive both primary prevention and nudge activities. At school lunchrooms, the fruits served in the school lunch will be put in a prominent position, in containers of bright and contrasting colors to serve them; create creative names for food served at meals will be created by the studentes, footprints that lead to them to water fountains will be painted on the floor. Several sports equipment (basketball hoops, volleyball nets, balls, ropes, shuttlecock and a lot of toys) will be available for use in the schools sport court. Also, classroom-based educational activities based on an earlier study, called PAPPAS, will be held. The activities will require 20 to 30 minutes, and teachers will be encouraged to reiterate the message during their lesson. The goal is to promote ten one-hour sessions of activity for each class.
