Objectives: Due to the COVID-19 pandemic, major changes to how, or even whether, we
work have occurred. This study examines associations of changing COVID-19-related
employment conditions with physical activity and sedentary behavior. Methods: Data from 2,303 US adults in employment prior to COVID-19 were collected April 3rd−7th, 2020. Participants reported whether their employment remained unchanged, they were working from home (WFH) when they had not been before, or they lost their job due to the pandemic. Validated questionnaires assessed physical activity, sitting time, and screen time. Linear regression quantified associations of COVID-19-related employment changes with physical activity, sitting time, and screen time, controlling for age, sex,
race, BMI, smoking status, marital status, chronic conditions, household location, public
health restrictions, and recalled physical activity, sitting time, and screen time prior to the COVID-19 pandemic
