Introduction: Sleep quality is an important component of health and well-being, yet evidence from crisis-affected settings, like Lebanon, remains limited. This study aimed to evaluate sleep quality and identify factors associated with poor sleep quality. Methods: A cross-sectional study using convenience sampling was conducted between July and October 2025. Sleep quality was assessed using the Pittsburgh Sleep Quality Index. Associations with poor sleep quality were examined using bivariate analyses and hierarchical logistic regression. Results: Overall, 418 participants answered the survey, of whom 51.4% were classified as having poor sleep quality. Age and sex were not significantly associated with poor sleep quality. A high perceived impact of the economic crisis (aOR=3.49; 95% CI: 1.34–9.49), moderate (aOR=2.21; 95% CI: 1.04–4.84), or high (aOR=4.10; 95% CI: 1.76–9.92) perceived impacts of the coronavirus pandemic were associated with higher odds of poor sleep quality. Similarly, obesity (aOR=2.12; 95% CI: 1.05–4.88) and postgraduate education (aOR=2.10; 95% CI: 1.16–3.87) were associated with higher odds of poor sleep quality. Medical insurance was associated with lower odds of poor sleep quality (aOR=0.48; 95% CI: 0.23–0.99). In contrast, a high perceived impact of the Beirut port explosion was associated with lower odds of poor sleep quality. Behavioral factors, including caffeine intake before sleep, sedentary behavior, and sleep disturbance from electricity cuts, were not significantly associated with poor sleep quality after adjustment. Conclusion: Several crisis-related and individual characteristics were associated with poor sleep quality. Findings can contribute to the understanding of sleep quality among Lebanese adults living in a crisis-affected setting.
