PAAPASNudge: Nudging Students Towards Healthy Diet and Physical Activity to Prevent Obesity
Study Details
Study Description
Brief Summary
The objective of the present study is to estimate the effect of nudging proposals on the students' Body Mass Index, based on changes made in the school environment. This is a factorial randomized community trial, which will be conducted in 18 public schools in the city of Duque de Caxias, RJ.

|---|---|
| Experimental: 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. |
Behavioral: Nudge
School lunchrooms are the central place of modifications regarding food consumption, where the following strategies will be conducted:
arrange the fruits served in the school lunch 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 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.

| Experimental: 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. |
Behavioral: 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.

| Experimental: Primary prevention + nudge This group will receive educational activities and in the classroomchanges in the school environment (nudge). |
Behavioral: 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.

Outcome Measures
Primary Outcome Measures
- Body mass Index (BMI) [1 year]
The body weight will be measured by a portable electronic scale with a segmental body composition monitor (Tanita BC-558). The height will be measure by a portable stadiometer (brand: "AlturaExata"). BMI will be calculated as weight/stature*stature.
Secondary Outcome Measures
- body fat percentage [1 year]
Body fat percentage will be measured by a portable electronic scale with a segmental body composition monitor (Tanita BC-558).
