The increased trends in psychological distress and mental illness have been of great significance in public health concerns. The study aimed to investigate the proportion and correlates of meeting 24-h movement guidelines (including moderate to vigorous physical activity, screen time and sleep duration) and the associations between 24-h movement guidelines met and mental well-being and psychological distress in a large sample of Chinese students.
All participants received a physical examination and filled out questionnaires in this study. Chi-square tests were used to analyse the proportion of reaching 24-h guidelines by gender and logistic regression was used to analyse correlates of meeting 24-h guidelines. Two binary logistic regression models were used to analyse the association between meeting 24-h guidelines and mental well-being and psychological distress. The back-propagation artificial neural network was used to describe the importance of the independent variables.
The findings revealed a generally low rate of meeting the 24-h movement guidelines, particularly concerning moderate to vigorous physical activity (16.5%). Meeting all three guidelines was related to better mental health in both boys and girls. Particularly, meeting screen time guideline and meeting sleep duration guideline appeared to be more important on mental outcomes, compared to meeting moderate to vigorous physical activity guideline. Compared with boys, girls were more susceptible to the influences of 24-h movement guidelines on mental health.
Meeting all three components of the 24-h movement guidelines was associated with the most favourable mental health outcomes for both boys and girls. Thus, maintaining a daily balance of sufficient physical activity, limited screen time, and adequate sleep is crucial for enhancing the mental health status of students.
心理困扰和精神疾病的上升趋势在公共卫生关注中具有重要意义。本研究旨在调查符合 24 小时运动指南（包括中等到剧烈的身体活动、屏幕时间和睡眠时间）的比例和相关因素，以及在大量中国学生样本中，符合 24 小时运动指南与心理健康和心理困扰之间的关联。
所有参与者都在这项研究中接受了体检和填写了问卷。使用卡方检验分析了性别达到 24 小时指南的比例，使用逻辑回归分析了符合 24 小时指南的相关因素。使用两个二元逻辑回归模型分析了符合 24 小时指南与心理健康和心理困扰之间的关联。使用反向传播人工神经网络来描述自变量的重要性。
研究结果表明，总体上符合 24 小时运动指南的比例较低，特别是关于中等到剧烈的身体活动（16.5%）。符合所有三个指南与男孩和女孩的心理健康都更好有关。特别是，与符合中等到剧烈的身体活动指南相比，符合屏幕时间指南和符合睡眠时长指南似乎对心理结果更为重要。与男孩相比，女孩更容易受到 24 小时运动指南对心理健康的影响。
符合 24 小时运动指南的所有三个组成部分都与男孩和女孩最有利的心理健康结果相关。因此，保持日常充足的身体活动、限制屏幕时间和充足的睡眠对于提高学生的心理健康状况至关重要。
