To examine the association of perceived stress [PS] with physical activity [PA] and sitting time [ST], before and during COVID-19 among US college students. : 592 students from a large Western university (19.08 ± 4.62 years, 76.69% female, 79.39% White) were recruited. : Self-reported online survey was completed in June-December 2020. Analysis included paired T-tests for continuous variables, Pearson Correlation the relationship between PSS, PA, and sitting time before and during COVID-19, and linear mixed models examined the association of outcome variables with PSS, time, and PSS × time. . Vigorous, moderate, and light PA decreased by 40%, 35% and 19%, sitting time increased by 52%, and PSS increase by 42% from before to during COVID-19. : The perceived stress during COVID-19 may have influenced physical activity and sitting time. Effective health promotion programs and coping strategies are needed to protect college students as campuses reopen during COVID.
为了在美国大学生中检查 COVID-19 前后感知压力（PS）与身体活动（PA）和久坐时间（ST）的关联。：从一所西部大型大学招募了 592 名学生（19.08±4.62 岁，76.69%为女性，79.39%为白人）。：在 2020 年 6 月至 12 月期间在线完成了自我报告调查。分析包括连续变量的配对 T 检验、COVID-19 前后 PSS、PA 和久坐时间之间的 Pearson 相关性，以及线性混合模型检查结果变量与 PSS、时间和 PSS×时间的关联。。剧烈、中度和轻度 PA 分别减少了 40%、35%和 19%，久坐时间增加了 52%，而 COVID-19 前后 PSS 增加了 42%。：COVID-19 期间的感知压力可能影响了身体活动和久坐时间。随着 COVID 期间校园重新开放，需要有效的健康促进计划和应对策略来保护大学生。
