Estudo com estudantes do ensino médio sobre o efeito da atividade física em ambiente verde e cinza

Abstract

This research investigated the effects of physical activity in green (open) and gray (closed) school environments on symptoms of anxiety, stress, and depression in high school students, a phase marked by academic pressures and biopsychosocial changes that increase vulnerability to mental health issues. This was a quasi-experimental study with non-randomized parallel groups involving 72 students (42 in the gray environment and 30 in the green environment) who underwent four interventions. A sociodemographic questionnaire, a qualitative instrument, and the Depression, Anxiety, and Stress Scale (DAES-A) were applied before and after the interventions. A statistically significant reduction in stress levels and the total scale score was observed after the interventions, although it was not possible to differentiate the specific impact of each environment due to limitations arising from the group structure, which influenced significant differences in scores even before the intervention. Academic performance, body dissatisfaction, and social support were identified as influencing symptom levels. It is concluded that, under appropriate conditions, physical activity associated with access to green spaces can contribute to the promotion of adolescents' mental health, reinforcing the need for interventions sensitive to the specificities of this population. The need for schools to go beyond preparing students for university entrance exams is emphasized, addressing other critical and mental health issues, thus contributing to the healthy development of these young people.
