Physical activity levels and mental health burden of healthcare workers during COVID‐19 lockdown

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.
