Using self-reported questionnaires, several studies found that social isolation during the COVID-19 pandemic has significantly changed the level of physical activity (PA) in children and adolescents. Since the objectivity of self-reported PA is limited in several ways, we used modern accelerometers in this study to assess the PA levels of male and female adolescents during the pandemic-related lockdown. Moreover, the association of PA with mental health of the adolescents were analyzed. A total of 136 students (76 girls, mean age of 16.28 ± 0.97 years) from various schools in Iran wore the accelerometer (ActiGraph GT3X-BT) for seven consecutive days. Mental health was measured through the Depression, Anxiety, Stress Scale-21 of Lovibond and Lovibond (1995). Descriptive statistics and independent -tests were used to analyze the PA levels of male and female students, and linear regressions were computed to examine whether PA predicts mental health status. On average, the daily time spent in moderate-to-vigorous PA (MVPA) was 18.47 min, which is clearly below the WHO guideline of at least 60 min of MVPA per day. Only 4% of adolescents showed MVPA for more than 30 min per day. Male students were significantly more active than their female peers ( = 0.015). As expected, MVPA was negatively associated with mental health issues such as depression, anxiety, and stress. However, the majority of adolescents reported symptoms of mild-to-moderate mental health disorders. These results emphasize the need for targeted strategies and offerings geared to young people's needs and preferences to promote an adequate level of PA and good mental health during and after the ongoing pandemic.
多项研究通过使用自我报告问卷发现，新冠疫情期间的社交隔离显著改变了儿童和青少年的身体活动（PA）水平。由于自我报告的身体活动在几个方面存在客观局限性，我们在本研究中使用现代加速度计来评估疫情相关封锁期间青少年的身体活动水平。此外，还分析了身体活动与青少年心理健康之间的关联。来自伊朗各学校的136名学生（76名女生，平均年龄16.28±0.97岁）连续七天佩戴加速度计（ActiGraph GT3X-BT）。通过Lovibond和Lovibond（1995年）编制的抑郁、焦虑、压力量表-21来测量心理健康状况。使用描述性统计和独立样本t检验来分析男女生的身体活动水平，并通过计算线性回归来检验身体活动是否能预测心理健康状况。平均而言，中度至剧烈身体活动（MVPA）的每日时长为18.47分钟，明显低于世界卫生组织每天至少60分钟的MVPA指南。只有4%的青少年每天的MVPA时长超过30分钟。男生的活动量明显高于女生（p = 0.015）。正如预期的那样，MVPA与抑郁、焦虑和压力等心理健康问题呈负相关。然而，大多数青少年报告有轻度至中度心理健康障碍的症状。这些结果强调，需要制定有针对性的策略并提供符合年轻人需求和偏好的服务，以在当前疫情期间及之后促进足够水平的身体活动和良好的心理健康。
