School is a favorable environment for the development of actions aimed at healthy behavioral changes. This project proposes to evaluate the effectiveness of an intervention program on aspects of lifestyle, with a focus on physical activity (PA) and reducing sedentary behaviors, and the relationship of these factors with the academic performance of students in the school from Florianopolis, SC, Brazil.
This is a randomized controlled intervention study enroling classes of 7th to 9th grade of fundamental education.
The intervention program will last for one year (about ten months), with three focuses: training of teachers, educational and environmental changes to behavior change.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| "The Movement" Program | Experimental | The intervention program was structured according three main components: (1) training and activities in general curriculum and Physical Education classes; (2) active facilities in the school environment; (3) health education in school community. |
|
| No intervention | No Intervention | Schools in the control group will maintain a regular academic year with conventional activities. Thus schools have two weekly Physical Education classes which are organized by according to the perspective of their teachers. Besides that, the Program "Saúde na Escola" is also performed. |

| The Movement Program | Behavioral | The program duration will be one academic year (around ten months) in 2017. The intervention strategies will focus on: (1) teachers' training and activities on health in curriculum; (2) active opportunities in the school environment (facilities and materials for PA practice) and (3) health education (posters and folders to students and parents). |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in weekly time in moderate-to-vigorous physical activity at 10 months | A list containing 24 types of PA will be used to measure the weekly frequency and the daily duration of each type of PA that the adolescents perform in a typical week. | baseline and 10-months of intervention |
| Change from baseline in the daily time using TV/computer/cellular/video games at 10 months | The daily time spent using TV/computer/video games of the individual will be estimated at baseline and after 10 months of intervention. | baseline and 4-months of intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in the healthy eating score at 10 months | Healthy eating score will be estimated using two items related to healthy foods (fruits and vegetables) and three unhealthy (soft drinks, savory and sweets) foods in a typical week. Points from this list will be estimated at baseline and after 10 months of intervention. | baseline and 10-months of intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in the score of intrapersonal PA mediators at 10 months | Points obtained from a list of attitude (5 items), expectations (10 items) and self-efficacy (12 items) variables will be estimated at baseline and after 4 months of intervention. | baseline and 10-months of intervention |
| Change from baseline in the score of interpersonal PA mediators at 10 months |
