COVID-19 Lockdown Impacts Physical Activity and Sedentary Time in Singapore Residents

Strategic Insights -

Social lockdowns and quarantines have been enforced in various populations to mitigate the spread of coronavirus disease 2019 (COVID-19) in the community. A recent study published in the Singapore Medical Journal investigated the impact of COVID-19 lockdown, known as circuit breaker movement restrictions (CBMR), on physical activity (PA) and sedentary time (ST) distribution patterns among Singapore residents aged 21-65 years. The study found a significant decrease in PA and an increase in physical inactivity and ST during the CBMR period. The researchers also noted that a greater proportion of participants reported sleeping for longer hours, suggesting positive adaptations in sleep habits during CBMR.

Key Takeaways:

  • A cross-sectional retrospective study of 44-item questionnaire found a significant decrease in PA and an increase in physical inactivity and ST during the CBMR period.
  • 50% of the respondents never used an online resource for exercise, and majority were unaware of online exercise initiatives and programs offered during the CBMR period.
  • Singapore residents seemed to prefer outdoor and facility-based venues for exercise and PA, and closure of facilities was the primary barrier for PA during the CBMR period.
  • Reduced PA and increased ST during CBMR reflect negative lifestyle adaptations and may have adverse public health implications.
  • Increased sleep duration suggests successful coping, which may consequently lead to physical and mental health benefits.
  • Singapore adult residents may be flexible with certain aspects of being physically active, but they seemed less adaptive to changes in type of exercise, facility, and environment.

Statistics:

  • 50% of the respondents never used an online resource for exercise.
  • 50% of the participants were unaware of online exercise initiatives and programs offered during the CBMR period.
  • 66% of the participants reported sleeping for longer hours during the CBMR period.
  • A significant reduction in PA was observed, with 75% of the participants reporting less physical activity during the CBMR period.
  • The primary barrier for PA during the CBMR period was the closure of facilities, with 55% of the participants citing this as a reason.
