Economic uncertainty and mental health: Global evidence, 1991 to 2019.

Mental health has deteriorated globally due to COVID-19, climate crisis, economic policies, and regional conflicts, requiring immediate attention. This study aims to comprehend the relationship between economic uncertainty and the prevalence of anxiety disorders, major depressive disorder, and eating disorders across various demographics and countries. Using robust fixed-effect models, we analyzed the relationship between economic uncertainty and mental disorders in 110 countries from 1991 to 2019. Our analysis also explored whether this association varies across genders and age groups. Our analysis indicates that economic uncertainty is associated with higher prevalence rates of anxiety and major depressive disorders, though no similar association is observed for eating disorders. In the subgroup analyses, while females have a significant association exclusively with anxiety disorders, males have associations with anxiety and major depressive disorders. The age-specific analyses show that economic uncertainty is associated with anxiety disorders for almost all age groups above 15 years, except for ages between 40 and 54. For major depressive disorders, this association becomes significant after the 40-44 age group. However, we see no significant association among age groups for eating disorders.
