The coronavirus disease 2019 (COVID-19) pandemic has increased the already high levels of stress that higher education students experience. Stress influences health behaviors, including those related to dietary behaviors, alcohol, and sleep; yet the effects of stress can be mitigated by resilience. To date, past research studying the connections between dietary behaviors, alcohol misuse, sleep, and resilience commonly investigated singular relationships between two of the constructs. The aim of the current study was to explore the relationships between these constructs in a more holistic manner using mediation and moderation analyses.
Higher education students from China, Ireland, Malaysia, South Korea, Taiwan, the Netherlands, and the United States were enrolled in a cross-sectional study from April to May 2020, which was during the beginning of the COVID-19 pandemic for most participants. An online survey, using validated tools, was distributed to assess perceived stress, dietary behaviors, alcohol misuse, sleep quality and duration, and resilience.
2254 students completed the study. Results indicated that sleep quality mediated the relationship between perceived stress and dietary behaviors as well as the relationship between perceived stress and alcohol misuse. Further, increased resilience reduced the strength of the relationship between perceived stress and dietary behaviors but not alcohol misuse.
Based on these results, higher education students are likely to benefit from sleep education and resilience training, especially during stressful events.
2019年冠状病毒病（COVID-19）大流行加剧了高等教育学生原本就很高的压力水平。压力会影响健康行为，包括与饮食行为、饮酒和睡眠相关的行为；然而，复原力可以减轻压力的影响。迄今为止，过去研究饮食行为、酒精滥用、睡眠和复原力之间联系的研究通常只调查了其中两个构念之间的单一关系。本研究的目的是通过中介和调节分析，以更全面的方式探索这些构念之间的关系。
来自中国、爱尔兰、马来西亚、韩国、台湾、荷兰和美国的高等教育学生于2020年4月至5月参加了一项横断面研究，这对大多数参与者来说是在COVID-19大流行开始期间。使用经过验证的工具进行在线调查，以评估感知压力、饮食行为、酒精滥用、睡眠质量和时长以及复原力。
2254名学生完成了该研究。结果表明，睡眠质量在感知压力与饮食行为之间的关系以及感知压力与酒精滥用之间的关系中起中介作用。此外，复原力的增强减弱了感知压力与饮食行为之间的关系强度，但没有减弱与酒精滥用之间的关系强度。
基于这些结果，高等教育学生可能会从睡眠教育和复原力培训中受益，尤其是在压力事件期间。
