UNLABELLED
The purpose of this study was to examine the impacts of academic stress on physical activity and sleep, and subsequently their impacts on anxiety and depression.
METHODS
This cross-sectional study collected data from a convenience sample of 1533 adolescents in an eastern province in China. Surveys were used to collect data on academic stress, anxiety, depression, sleep, physical activity, and demographics. Descriptive statistics, correlation analysis, and path analysis were used to analyze data.
RESULTS
The participants reported about 6.77 ± 0.89 h of sleep per day and 1.62 ± 1.79 days of 60 min of physical activity each week. Academic stress was positively correlated with anxiety and depression, which were negatively correlated with physical activity and sleep. The path analysis showed that academic stress directly predicted anxiety (β = 0.54) and depression (β = 0.55), and hours of sleep (β = 0.024) and the number of days of 60 min physical activity (β = 0.014) mediated the relation.
CONCLUSION
The results largely supported our hypotheses and supported the need to lessen academic stress experienced by Chinese adolescents, in effort to enhance mental health indices directly, and by allowing for engagement in health-related behaviors such as physical activity and sleep.
本研究旨在探讨学业压力对身体活动和睡眠的影响，以及它们对焦虑和抑郁的后续影响。
方法
本横断面研究从中国东部一个省份的便利样本中收集了 1533 名青少年的数据。调查用于收集学业压力、焦虑、抑郁、睡眠、身体活动和人口统计学数据。采用描述性统计、相关分析和路径分析对数据进行分析。
结果
参与者报告每天约有 6.77±0.89 小时的睡眠时间和每周 1.62±1.79 天进行 60 分钟的身体活动。学业压力与焦虑和抑郁呈正相关，而焦虑和抑郁与身体活动和睡眠呈负相关。路径分析表明，学业压力直接预测焦虑（β=0.54）和抑郁（β=0.55），而睡眠时间（β=0.024）和 60 分钟身体活动天数（β=0.014）则中介了这种关系。
结论
研究结果在很大程度上支持了我们的假设，并支持减轻中国青少年所经历的学业压力的必要性，以直接提高心理健康指数，并促进身体活动和睡眠等与健康相关的行为。
