Adolescents' daily life has dramatically changed during the COVID-19 era due to the social restrictions that have been imposed, including closures of schools, leisure centers and sport facilities. The purpose of this study was to examine levels of well-being and mood and their relations with physical (in)activity and eating behaviors in adolescents during a lockdown period in Greece. A total of 950 adolescents (Mean Age = 14.41 years ± 1.63) participated in a web-based survey while education was conducted online and organized sport activities were interrupted. Participants showed poor well-being, insufficient physical activity levels and moderate scores of healthy eating behavior. Hierarchical regression analysis showed that, after controlling for the effect of gender and body mass index, increased physical activity and healthier eating behavior predicted better well-being (b = 0.24, < 0.01 and b = 0.19, < 0.01, respectively), whereas sedentariness predicted worse well-being (b = -0.16, < 0.01). Furthermore, it was revealed that days of physical activity per week was a stronger predictor of well-being than minutes of physical activity per week, and that both in-house and out-of-house physical activity were beneficial. Considering that well-being in our study was below the threshold recommended by the World Health Organization as indicative of possible depressive symptoms, measures to increase physical activity, decrease sedentariness and improve eating behavior should become a priority for communities and policy makers.
由于实施了社会限制，包括学校、休闲中心和体育设施关闭，青少年在 COVID-19 时代的日常生活发生了巨大变化。本研究的目的是在希腊封锁期间，检查青少年的幸福感和情绪水平及其与身体（不）活动和饮食行为的关系。共有 950 名青少年（平均年龄= 14.41 岁±1.63 岁）参加了一项基于网络的调查，当时教育是在线进行的，组织的体育活动也中断了。参与者表现出较差的幸福感、不足的身体活动水平和中等水平的健康饮食行为。分层回归分析表明，在控制性别和体重指数的影响后，增加身体活动和更健康的饮食行为预测更好的幸福感（b = 0.24， < 0.01 和 b = 0.19， < 0.01，分别），而久坐不动预测更差的幸福感（b = -0.16， < 0.01）。此外，还发现每周的身体活动天数比每周的身体活动分钟数更能预测幸福感，而且室内和室外身体活动都有益。考虑到我们的研究中的幸福感低于世界卫生组织建议的可能抑郁症状的阈值，增加身体活动、减少久坐不动和改善饮食行为的措施应该成为社区和决策者的优先事项。
