Impact of COVID-19 'Stay Home, Stay Healthy' Orders on Function among Older Adults Participating in a Community-Based, Behavioral Intervention Study.

Background: Early mitigation orders for COVID-19 halted participation in community-based programs. We examined the early impact of "Stay Home, Stay Healthy" orders on functioning in older adults participating in a behavioral intervention study involving community-based exercise. Methods: A quasi-natural experiment, using mixed methods (n = 39). Participants completed interviews and questionnaires after 3-4 weeks of the Stay Home, Stay Healthy directive. PROMIS-29 outcomes were compared to pre-COVID-19 responses. Results: Participants had a mean age of 74.1 (6.5) years, 79.5% were women, and 20.5% were racial/ethnic minorities. Compared to pre-COVID-19, there was a significant increase in anxiety and decrease in fatigue and social participation. Thematic analysis revealed five main themes related to disruption of daily life, the emotional and physical impact of stay-at-home orders, unexpected positive outcomes, and perspectives on messaging surrounding the pandemic. Conclusions: Efforts to curb the spread of COVID-19 have substantially impacted the lives of older adults participating in community-based exercise.
