Strategies consisted of group discussion, some physical activities, phone support, and printed materials. The content and strategies were elaborated by a team formed by a doctor, nutritionists, a psychologist, and physical education professionals and the main aim was to promote the engagement in physical activity, working not only on behavioral change but also on the environment attributes available for physical activity practice. The main strategy was the group discussion, which sessions lasted 120 minutes each and its frequency changed as follow: in the first month they were weekly; in the second occurred twice per month; and in the third month onwards sessions were monthly. All sessions occurred in the Primary Health Unit or inside a community association building.
