Background: Although global efforts have resulted in improvements in health and well-being across the world, economic downturns can rapidly undermine achievements in this area. Methods: Using Gallup World Poll data (n = 7,084) this study assessed the changes in health status and well-being before (2009-2013) and during (2015-2017) the current financial and political crisis in Brazil and their association with the Social Determinants of Health Inequalities. Health and well-being were measured by the Personal Life Index and the Life Evaluation Index. Descriptive analysis and logistic regression models were conducted. Results: A significant deterioration of well-being was found during the crisis, with a 29% decline (63-44%) in the prevalence of respondents classified as 'thriving' in life. Food security, age and social support were the best predictors of health status and well-being, mitigating the association of health and well-being with income and unemployment. Education and community environment also showed strong association with well-being, and satisfaction with healthcare system played an important role in health status. Conclusions: In order to protect health and well-being during such crisis, policies should pay particular attention on enhancing the access to food, healthcare system, educational system, community environment (quality of air, water and infrastructure) and fostering social support.
