Research on the combined role of 24-hour movement behaviors (sleep, sedentary behavior [SB], and physical activity) in adult mental health, though important, is in its infancy. In the context of Canadian 24-hour movement guidelines integrating quantitative recommendations for sleep, SB, and moderate-to-vigorous physical activity (MVPA), this study aimed to examine the associations between meeting guidelines and mental health among college students. The study used a cross-sectional sample of 1846 Chinese college students surveyed online in August 2020. Through network analysis and multivariate analysis of covariance, the individual and combined associations between meeting 24-hour movement guidelines and the levels of depression and anxiety after adjusting sociodemographic factors were analyzed. Results indicated that meeting the sleep guideline had stronger associations with depression and anxiety than meeting the SB or MVPA guideline. Specifically, compared to meeting no guidelines, meeting the sleep guideline (alone or in combination with other guidelines) was associated with significantly lower levels of depression and anxiety; meeting both SB and MVPA guidelines was also associated with a significantly lower level of depression. Hence, meeting more guidelines, especially adhering to a healthy sleep routine, may play an important role in promoting the mental health of young adults.
关于24小时运动行为（睡眠、久坐行为和身体活动）对成人心心理健康的综合作用的研究，尽管很重要，但仍处于起步阶段。在加拿大24小时运动指南整合了关于睡眠、久坐行为和中度至剧烈身体活动（MVPA）的定量建议的背景下，本研究旨在探讨大学生中符合指南情况与心理健康之间的关联。该研究采用了2020年8月在线调查的1846名中国大学生的横断面样本。通过网络分析和多变量协方差分析，分析了在调整社会人口学因素后，符合24小时运动指南与抑郁和焦虑水平之间的个体及综合关联。结果表明，与符合久坐行为或中度至剧烈身体活动指南相比，符合睡眠指南与抑郁和焦虑的关联更强。具体而言，与不符合任何指南相比，符合睡眠指南（单独或与其他指南结合）与抑郁和焦虑水平显著降低相关；同时符合久坐行为和中度至剧烈身体活动指南也与抑郁水平显著降低相关。因此，符合更多指南，尤其是坚持健康的睡眠习惯，可能对促进年轻人的心理健康发挥重要作用。
