The COVID-19 pandemic is associated with psychological distress. Decreased moderate-vigorous physical activity (MVPA) and increased sedentary time may be exacerbating pandemic-related symptoms of anxiety and depression, but existing studies exploring these associations are almost entirely cross-sectional.
Reported data from 2018 and Summer 2020 were used to create change categories based on compliance with MVPA guidelines and relative sedentary time. Participants completed the Patient Health Questionnaire-4 (PHQ-4) in Summer 2020. Associations among changes in MVPA and sedentary time (separately and jointly) with psychological distress (total PHQ-4 score) were examined with ordinal logistic regression and associations with depressive or anxiety symptoms were examined with logistic regression.
Among 2,240 participants (65% women, mean age 57.5 years), 67% increased sedentary time and 21% became inactive between the two time points. After multivariate adjustment, participants who became (OR = 1.71, 95% CI: 1.05-2.78) or remained inactive (OR = 2.07, 1.34-3.22) were more likely to experience depressive symptoms compared to those who remained active. Participants who increased sedentary time were also more likely to experience depressive symptoms compared to those who maintained sedentary time (OR = 1.78, 1.13-2.81). Jointly, those who increased sedentary time while remaining (OR = 3.67, 1.83-7.38) or becoming inactive (OR = 3.02, 1.44-6.34) were much more likely to have depressive symptoms compared to the joint referent (remained active/maintained sedentary time). Associations with anxiety symptoms were not statistically significant.
These findings support the value of promoting MVPA and limiting sedentary time during stressful events associated with psychological distress, like the COVID-19 pandemic.
新冠疫情与心理困扰相关。中高强度身体活动（MVPA）减少以及久坐时间增加可能会加剧与疫情相关的焦虑和抑郁症状，但现有探索这些关联的研究几乎全是横断面研究。
利用2018年和2020年夏季报告的数据，根据对MVPA指南的遵循情况和相对久坐时间创建变化类别。参与者于2020年夏季完成患者健康问卷-4（PHQ-4）。采用有序逻辑回归分析MVPA和久坐时间变化（分别及联合）与心理困扰（PHQ-4总分）之间的关联，采用逻辑回归分析与抑郁或焦虑症状之间的关联。
在2240名参与者中（65%为女性，平均年龄57.5岁），67%的人久坐时间增加，21%的人在两个时间点之间变得缺乏运动。多变量调整后，与保持活跃的参与者相比，变得（比值比[OR]=1.71，95%置信区间[CI]：1.05-2.78）或一直缺乏运动（OR=2.07，1.34-3.22）的参与者更易出现抑郁症状。与保持久坐时间的参与者相比，久坐时间增加的参与者也更易出现抑郁症状（OR=1.78，1.13-2.81）。总体而言，与联合参照组（保持活跃/保持久坐时间）相比，久坐时间增加同时保持（OR=3.67，1.83-7.38）或变得缺乏运动（OR=3.02，1.44-6.34）的参与者出现抑郁症状的可能性要高得多。与焦虑症状的关联无统计学意义。
这些发现支持在诸如新冠疫情这种与心理困扰相关的压力事件期间促进MVPA并限制久坐时间的价值。
