Health Behaviors at the Onset of the COVID-19 Pandemic.

We examined perceived behavior change since implementation of physical distancing restrictions and identified modifiable (self-rated health, resilience, depressive symptoms, social support and subjective wellbeing) and non-modifiable (demographics) risk/protective factors. A representative US sample (N = 362) completed an online survey about potential risk/protective factors and health behaviors prior to the pandemic and after implemented/recommended restrictions. We assessed change in perceived health behaviors prior to and following introduction of COVID-19. We conducted hierarchical linear regression to explore and identify risk/protective factors related to physical activity, diet quality, and social isolation. There have been substantial decreases in physical activity and increases in sedentary behavior and social isolation, but no changes in diet quality since COVID-19. We identified modifiable and non-modifiable factors associated with each health behavior. Negative effects indicate the need for universal intervention to promote health behaviors. Inequalities in health behaviors among vulnerable populations may be exacerbated since COVID-19, suggesting need for targeted invention. Social support may be a mechanism to promote health behaviors. We suggest scaling out effective health behavior interventions with the same intensity in which physical distancing recommendations were implemented.
