This study assessed the effects of a 12-week afterschool mindfulness-based diet and exercise intervention on mental and physical health in Latinx and Black youth. One hundred forty-eight boys and girls (average age = 10.1 years, SD = 1.3 years; 52% girls; 72.3% Latinx) were randomized to either the experimental group ( = 80) or the control group ( = 68). The experimental group participants engaged in fitness yoga, kickboxing, and/or spinning sessions, and mindfulness practices (e.g., breathing, meditation, and mindful eating) twice per week for 12 weeks. The control group participants engaged in a recreational play session once per week for 12 weeks. All participants completed surveys (demographics, acculturation, anxiety, emotional eating, sleep, and food intake) and had their height, weight, and percent body fat measured pre- and post-intervention. Participants wore an accelerometer for 7 days pre- and post-intervention. Repeated measures analysis of covariance indicated that the experimental group participants reported lower scores in emotional eating, anxiety, and sleep latency post-intervention compared to the control group participants. Conversely, no significant differences were observed in physical activity between the experimental and control group participants post-intervention. These findings indicate that a mindfulness-based intervention has a positive effect on emotional eating, anxiety, and sleep latency among youth of color.
本研究评估了一项为期12周的基于正念的课后饮食与运动干预对拉丁裔和黑人青少年身心健康的影响。148名男孩和女孩（平均年龄 = 10.1岁，标准差 = 1.3岁；52%为女孩；72.3%为拉丁裔）被随机分为实验组（n = 80）或对照组（n = 68）。实验组参与者每周进行两次健身瑜伽、跆拳道和/或动感单车课程以及正念练习（如呼吸、冥想和正念饮食），为期12周。对照组参与者每周进行一次娱乐游戏活动，为期12周。所有参与者均完成了调查问卷（人口统计学、文化适应、焦虑、情绪化饮食、睡眠和食物摄入量），并在干预前后测量了身高、体重和体脂百分比。参与者在干预前后佩戴加速度计7天。重复测量协方差分析表明，与对照组参与者相比，实验组参与者在干预后报告的情绪化饮食、焦虑和睡眠潜伏期得分较低。相反，干预后实验组和对照组参与者在身体活动方面未观察到显著差异。这些发现表明，基于正念的干预对有色人种青少年的情绪化饮食、焦虑和睡眠潜伏期有积极影响。
