Global prevalence of anxiety disorders varies significantly by culture and demographics
In short: A systematic review of 87 studies across 44 countries found that the global current prevalence of anxiety disorders, when adjusted for methodology, is approximately 7.3%. The researchers observed that factors such as gender, age, culture, and economic status are major drivers of how common these disorders appear in different populations.
The researchers analyzed data from decades of prevalence studies to identify why estimates vary so widely. While they identified key substantive drivers like urbanicity and conflict, they also noted that methodological differences, such as the diagnostic instruments used, contribute to the variability. However, the findings are based on a synthesis of existing studies, which may inherit the biases of the original research.
Why it matters: Understanding cultural and demographic context is essential for accurately measuring the global burden of anxiety.
