About The Study: The findings of this study suggest a consistent, widespread, and significant decline in activity following the onset of COVID-19 in the United States. Vulnerable populations, including individuals at a lower socioeconomic status and those reporting worse mental health in the early COVID-19 period, were at the highest risk of reduced activity. The researchers found a significant decline in daily step counts that persisted even after most COVID-19–related restrictions were relaxed, suggesting COVID-19 affected long-term behavioral choices. It is currently unknown whether this reduction is steps is clinically meaningful over time.
