The outbreak of COVID-19 has precipitated international lockdown measures to curb disease transmissions. The closure of public activity spaces as well as changes in pandemic workload may disrupt healthcare workers' physical activity and self-care routines. We sought to examine the association between physical activity levels and mental health burden of healthcare workers during the COVID-19 lockdown in Singapore. This cross-sectional study comprised of an multidomain survey that was administered digitally to 707 healthcare workers between 17 May and 18 June 2020. Exercise frequency, duration and intensity of these healthcare workers had reduced significantly during the lockdown compared to pre-lockdown. 25.3%, 37.2%, and 11.9% had screened positive for moderate-to-extremely-severe depression, anxiety and stress respectively. Reductions in exercise duration was a significant risk factor for mild stress and moderate-to-severe depression while increase in exercise frequency was found to be a protective factor against depressed mood. Our study revealed that a short-term reduction in physical activity levels during lockdown was associated with poorer psychological outcomes. Given the protection that exercise confers on depression, physical activity should be promoted at the workplace and at home to support healthcare workers to cope through this protracted health crisis.

COVID-19 封锁期间医护人员的身体活动水平和心理健康负担

COVID-19 的爆发促成了国际封锁措施，以遏制疾病传播。公共活动空间的关闭以及大流行工作量的变化可能会扰乱医护人员的身体活动和自我保健程序。我们试图研究新加坡 COVID-19 封锁期间身体活动水平与医护人员的心理健康负担之间的关联。这项横断面研究包括一项多领域调查，该调查在 2020 年 5 月 17 日至 6 月 18 日期间对 707 名医护人员进行了数字化管理。与封锁前相比，封锁期间这些医护人员的运动频率、持续时间和强度显着降低。分别有 25.3%、37.2% 和 11.9% 的中度至极重度抑郁、焦虑和压力筛查呈阳性。运动时间的减少是轻度压力和中度至重度抑郁症的重要危险因素，而运动频率的增加被发现是对抗抑郁情绪的保护因素。我们的研究表明，在封锁期间身体活动水平的短期减少与较差的心理结果有关。鉴于运动对抑郁症的保护作用，应在工作场所和家中促进体育锻炼，以支持医护人员应对这场旷日持久的健康危机。我们的研究表明，在封锁期间身体活动水平的短期减少与较差的心理结果有关。鉴于运动对抑郁症的保护作用，应在工作场所和家中促进体育锻炼，以支持医护人员应对这场旷日持久的健康危机。我们的研究表明，在封锁期间身体活动水平的短期减少与较差的心理结果有关。鉴于运动对抑郁症的保护作用，应在工作场所和家中促进体育锻炼，以支持医护人员应对这场旷日持久的健康危机。
