Trends in the incidence and DALYs of anxiety disorders at the global, regional, and national levels: Estimates from the Global Burden of Disease Study 2019.

2022 
Abstract Background Anxiety disorders are the second leading mental health-related cause of disability-adjusted life-years (DALYs) and years lived with disability (YLDs) worldwide. This study aimed to quantitatively assess the burden of anxiety disorders at the global, regional, and national levels in 1990 and 2019 and the trends over this period. Methods We used data for incidence cases, DALYs, age-standardized incidence rate (ASIR) and age-standardized DALYs rate (ASDR) from Global Burden of Disease Study 2019 (GBD 2019) and calculated the estimated annual percentage changes (EAPCs) to assess the incidence rate and DALYs rate trends for anxiety disorders. Results The incidence cases of anxiety disorders increased by 47.19%, from 31.13 million in 1990 to 45.82 million in 2019, and DALYs increased by 53.70%, from 18.66 million in 1990 to 28.68 million in 2019. Over the past 29 years, the changes of ASIR and ASDR worldwide were stable (EAPC = 0.011 and -0.001, respectively). Women were more likely to experience anxiety disorders. Participants aged 10–14 had the highest incidence rate, followed by those aged 35–44. Those aged 15–19 and 40–44 had the highest estimated DALYs rate. The ASIR and ASDR were estimated to be the highest in Iran and Portugal, and Portugal and Brazil, respectively. Both of ASIR and ASDR were high in high- sociodemographic index regions in 2019. Limitations Further exploration of related risk factors needs to be analyzed in the future studies. Conclusions Compared with 1990, the absolute increase in incidence cases and DALYs of anxiety disorders in 2019 still remained high. Our findings contribute to the formulation of health policies for controlling and preventing anxiety disorders in different countries and regions.
