Coronavirus disease 2019 (COVID-19) has brought significant challenges to the ability of those with memory problems to stay active and age in place. This study investigated the roles of neighborhood environments in helping community-dwelling people with memory problems maintain physical activity during the COVID-19 pandemic.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Research Design and Methods<\/jats:title>\n                  <jats:p>We used retrospective online survey data from 75 caregivers who responded on behalf of their care recipients with memory problems living in Texas communities. We used difference-in-difference (DID) estimations based on zero-inflated negative binomial regression models to examine the changes in recreational walking and moderate-to-strenuous exercise before and during the COVID-19 pandemic and whether such changes vary by diversity of walkable neighborhood destinations.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>In the total sample, there was a significant reduction in both recreational walking (\u0394 change\u2005=\u2005\u221245.16\u2005min\/week, p\u2005&amp;lt;\u2005.001) and exercise (\u0394 change\u2005=\u2005\u221236.28\u2005min\/week, p\u2005=\u2005.03) after the COVID-19 outbreak. The pandemic\u2019s impact on exercise varied by diversity of neighborhood destinations (DID\u2005=\u20050.81, p\u2005=\u2005.03). Those living in neighborhoods with diverse walkable destinations experienced less decline in physical activity compared to those living in areas with limited destinations.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion and Implications<\/jats:title>\n                  <jats:p>These findings suggest that the impact of the COVID-19 pandemic on physical activity among people with memory problems may be partially explained by neighborhood land-use characteristics. Destination-rich, mixed-use neighborhood environments can help people with memory problems stay active even during pandemics such as COVID-19 in the United States and potentially elsewhere.<\/jats:p>\n
