The aim of this study was to examine physical activity and sedentary behaviours during Western Australia's COVID-19 lockdown and their association with mental well-being.
Participants completed activity related questions approximately two months after a three-month lockdown (which formed part of a larger cross-sectional study from August to October 2020) as part of a 25-minute questionnaire adapted from the Western Australia Health and Well-being Surveillance system. Open-ended questions explored key issues relating to physical activity behaviours.
During the lockdown period, 463 participants (female, n = 347; 75.3%) reported lower number of active days (W = 4.47 p < .001), higher non-work-related screen hours per week (W = 11.8 p < .001), and higher levels of sitting time (χ=28.4 p < .001). Post lockdown body mass index was higher (U = 3.0 p = .003), with obese individuals reporting the highest non-work-related screen hours per week (Wald χ= 8.9 p = .012). Inverse associations were found for mental well-being where higher lockdown scores of Kessler-10 (p = .011), Dass-21 anxiety (p = .027) and Dass-21 depression (p = .011) were associated with lower physical activity levels. A key qualitative message from participants was wanting to know how to stay healthy during lockdown.
Lockdown was associated with lower physical activity, higher non-work-related screen time and more sitting time compared to post lockdown which also reported higher body mass index. Lower levels of mental well-being were associated with lower physical activity levels during lockdown. Given the known positive affect of physical activity on mental well-being and obesity, and the detrimental associations shown in this study, a key public health message should be considered in an attempt to maintain healthy activity behaviours in future lockdowns and similar emergency situations to promote and maintain positive well-being. Furthermore, consideration should be given to the isolation of a community due to infectious disease outbreaks and to recognise the important role physical activity plays in maintaining weight and supporting good mental health.
本研究旨在探讨澳大利亚西部 COVID-19 封锁期间的体力活动和久坐行为及其与心理健康的关系。
参与者在三个月的封锁期（作为 2020 年 8 月至 10 月期间一项更大的横断面研究的一部分）大约两个月后完成了与活动相关的问题，这些问题是从西澳大利亚健康和幸福感监测系统改编而来的 25 分钟问卷的一部分。开放式问题探讨了与体力活动行为相关的关键问题。
在封锁期间，463 名参与者（女性，n=347；75.3%）报告活跃天数减少（W=4.47，p<.001），每周非工作相关屏幕时间增加（W=11.8，p<.001），久坐时间增加（χ=28.4，p<.001）。封锁后体重指数更高（U=3.0，p=.003），肥胖个体报告每周非工作相关屏幕时间最长（Wald χ=8.9，p=.012）。心理健康状况呈反比，Kessler-10 评分较高（p=.011）、Dass-21 焦虑评分（p=.027）和 Dass-21 抑郁评分（p=.011）与较低的体力活动水平相关。参与者的一个关键定性信息是想知道如何在封锁期间保持健康。
与封锁后相比，封锁期间体力活动减少，非工作相关屏幕时间增加，久坐时间增加，体重指数也增加。封锁期间心理健康水平较低与体力活动水平较低有关。鉴于体力活动对心理健康和肥胖的积极影响，以及本研究中显示的不利关联，应该考虑传达一个关键的公共卫生信息，以试图在未来的封锁和类似的紧急情况下保持健康的活动行为，以促进和维持积极的幸福感。此外，应该考虑到传染病爆发导致的社区隔离，并认识到体力活动在维持体重和支持良好心理健康方面的重要作用。
