This study sought to explore the association between changes in daily life and war-related anxiety. In this study, we analyzed self-reported data from 2,004 Ukrainian adults, obtained through an opportunistic survey in the Ukraine. Our assessment focused on changes in everyday routines and generalized anxiety symptoms since the Russian invasion of Ukraine on the 24 February 2022. The data were collected between July-September 2022. Results show a significant dose-response connection between everyday routine changes and increased war-related anxiety. Not surprisingly, the ongoing Ukraine-Russia conflict is impacting the lives of Ukrainians. These changes are linked to heightened anxiety levels. Effective population-based crisis management should consider both war-related stressors and changes in daily life routines.
