Physical inactivity is associated with a greater risk of frailty, neuropsychiatric symptoms, worse quality of life, and increased risk for Alzheimer’s disease. Little is known about how physical activity engagement of older adults during the COVID-19 pandemic relates to subjective cognitive concerns and management of emotional distress. This study aimed to examine whether there were changes in physical activity during the pandemic in older adults at baseline and 3 months compared to before the pandemic and whether these changes varied based on age, sex, income level, and employment status. Further, we examined whether individuals who reported engaging in less physical activity experienced greater subjective cognitive difficulties and symptoms of depression and anxiety than those who maintained or increased their physical activity levels.

301 participants (73% non-Hispanic whites) completed an online survey in either English or Spanish between May and October 2020 and 3 months later. The Everyday Cognition Scale was used to measure subjective cognitive decline, the CES-D-R-10 scale to measure depressive symptoms, and the GAD-7 scale to measure anxiety symptoms. Changes in physical activity were measured with the question “Since the coronavirus disease pandemic began, what has changed for you or your family in regard to physical activity or exercise levels?” with options “less physical activity,” “increase in physical activity,” or “same activity level.” Income was self-reported as high, middle, or low. Analyses of chi-squared tests were used to examine differences in physical activity maintenance by age, income level, sex, and employment status.

Most individuals (60%) reported having decreased their physical activity levels during the pandemic, at baseline and 3-month followup. There were differences in physical activity levels based on income and age: participants with a high income reported engaging in more physical activity than those with low income (X^2=4.78, p =.029). At the 3-month follow-up, middle-income participants reported being less active than the high-income earners (X^2=8.92, p=.003), and younger participants (55-65 years, approximately) reported being less active than older participants (X^2=5.28, p =.022). Those who reported an increase in their physical activity levels had fewer cognitive concerns compared to those who were less active at baseline, but this difference was not seen in the 3-month follow-up. Participants of all ages who reported having maintained or increased their physical activity levels had fewer depressive symptoms than those who were less active (p < 0.0001). Those who reported maintaining their physical activity levels exhibited fewer anxiety symptoms than those who were less active (p < 0.01).

Older adults reported changes in physical activity levels during the pandemic and some of these changes varied by sociodemographic factors. Further, maintaining physical activity levels was associated with lower symptoms of depression, anxiety, and cognitive concerns. Encouraging individuals and providing resources for increasing physical activity may be an effective way to mitigate some of the pandemic’s adverse effects on psychological wellbeing and may potentially help reduce the risk for cognitive decline. Alternately, it is possible that improving emotional distress could lead to an increase in physical activity levels and cognitive health.
