Abstract

Purpose: To test the effects of a physical activity intervention program on symptoms of mental disorders among adolescents.

Methods: This study is a 12-week cluster randomized controlled trial. The sample consisted of 306 adolescents (45,8% male, age: 13,6 [0,72] years; 54.2% female, age: 13.5 [0.69] years), randomized into an intervention group (N = 165) and a control group (N = 141). The physical activity program involved sessions including muscle strengthening and cardiorespiratory exercises and lifestyle guidance. The mental health indicators analyzed were: anxiety, depression, sleep, and psychological well-being. Intervention effects were analyzed by generalized estimating equations.

Results: After 12 weeks, no significant improvements were observed in the intervention group for sleep; anxiety; depression, and psychological well-being. In the subgroup analysis, significant group×time interactions were observed for adolescents who were classified with moderate symptoms of depression (mean difference: -0.97, p = 0.002) and anxiety (mean difference: -3.03, p = 0.01) with favorable effects for intervention group.

Conclusion: After the 12-week intervention period, it can be concluded that 12 weeks of school-based physical activity intervention significantly reduced symptoms of anxiety and depression in adolescents with moderate/severe symptoms. Furthermore, the intervention contributed to the maintenance of psychological well-being, since the control group showed a significant reduction in this mental health indicator.

以学校为基础的体育活动干预对巴西青少年心理健康指标的影响：一项聚类随机对照试验

目的：检验体育活动干预方案对青少年精神障碍症状的影响。方法：采用为期12周的整群随机对照试验。样本由306名青少年组成，其中45.8%为男性，年龄：13.6[0.72]岁；女性54.2%，年龄：13.5[0.69]岁)，随机分为干预组（N = 165）和对照组（N = 141）。体育锻炼项目包括肌肉强化、心肺锻炼和生活方式指导。分析的心理健康指标为：焦虑、抑郁、睡眠和心理健康。采用广义估计方程分析干预效果。结果：12周后，干预组在睡眠方面无明显改善；焦虑;抑郁和心理健康。在亚组分析中，青少年抑郁中度症状（平均差异：-0.97,p = 0.002）和焦虑中度症状（平均差异：-3.03,p = 0.01）的交互作用显著，干预组效果较好。结论：经过12周的干预期，12周的校本体育活动干预可显著降低中重度症状青少年的焦虑和抑郁症状。此外，干预有助于维持心理健康，因为对照组的这一心理健康指标显著降低。
