BACKGROUND/OBJECTIVE: This study aimed to examine the associations between physical activity (PA), sedentary behavior, sleep and posttraumatic stress disorder (PTSD) among undergraduate students during the coronavirus disease 2019 (COVID-19) pandemic in China.
A total of 3178 university students responded to an online questionnaire between December 2020 and January 2021. Participants self-reported the time they spent on PA, screen time and sleep after (over the past seven days) and during the outbreak peak (from January to March 2020). Their sleep quality was measured using the Chinese version of the Pittsburgh Sleep Quality Index. The Chinese version of the Posttraumatic Stress Disorder Checklist - Civilian Version was used to measure PTSD. Logistic regressions and generalized linear mixed models were conducted.
The final analysis included data from 2070 university students (20.2 ± 1.3 years old, 37.0% males). The prevalence of PTSD was 7.1%. Better sleep quality both during and after the outbreak peak, and longer sleep duration after the outbreak peak were associated with a lower odds ratio of having PTSD and lower re-experiencing, avoidance and hyperarousal scores. Higher total PA levels during the outbreak peak were associated with a higher odds ratio of having PTSD and higher levels of re-experiencing and avoidance.
Sleep quality and duration were negatively associated with PTSD among university students during the COVID-19 pandemic. The associations between PA, screen time and PTSD require further examination. Future interventions to enhance mental health could consider targeting university students' sleep hygiene.
背景/目的：本研究旨在探讨2019年冠状病毒病（COVID-19）疫情期间中国大学生的身体活动（PA）、久坐行为、睡眠与创伤后应激障碍（PTSD）之间的关联。
2020年12月至2021年1月期间，共有3178名大学生回复了一份在线问卷。参与者自行报告了疫情爆发高峰后（过去七天）以及爆发高峰期（2020年1月至3月）他们花在身体活动、屏幕使用时间和睡眠上的时间。使用中文版匹兹堡睡眠质量指数测量他们的睡眠质量。采用中文版创伤后应激障碍检查表 - 平民版来测量创伤后应激障碍。进行了逻辑回归和广义线性混合模型分析。
最终分析纳入了2070名大学生的数据（年龄20.2±1.3岁，男性占37.0%）。创伤后应激障碍的患病率为7.1%。疫情爆发高峰期及之后睡眠质量较好，以及爆发高峰期后睡眠时间较长，与患创伤后应激障碍的较低比值比以及较低的再体验、回避和过度觉醒得分相关。疫情爆发高峰期较高的总体身体活动水平与患创伤后应激障碍的较高比值比以及较高的再体验和回避水平相关。
在COVID-19疫情期间，大学生的睡眠质量和时长与创伤后应激障碍呈负相关。身体活动、屏幕使用时间与创伤后应激障碍之间的关联需要进一步研究。未来促进心理健康的干预措施可考虑针对大学生的睡眠卫生。
