Estágios de mudança de comportamento relacionado à atividade física após uma intervenção escolar: O projeto Educação Física+

Abstract

The present study aimed to evaluate the Stages of Behavior Change (EMC) for physical activity after two years of application and an intervention in physical activity and health with an educational approach. A cross-sectional study was conducted with a sample of 8071 students with a mean age of 13.9 (SD ± 2.36) years. The prevalence of students in active MCAs was high, with 21.8% and 41.6% of the students being classified in the Action and Maintenance stages, specifically. The time of exposure to the intervention had no significant association with CMEs. The male sex was more associated with the Stages of Action (RR1.28, 95% CI 1.07-1.54, p = 0.006) and Maintenance (RR 3.57, CI95% 3,024.23, p <0.001) in Compared to females. The variable index of goods obtained a direct relation with the Stages of Action and of Maintenance. However, the main outcome relates to health knowledge, which was directly related to CMEs. Conducting interventional studies with longitudinal assessments of CMEs could broaden the knowledge about the effects of school-based interventions on physical activity practice.
