Anxiety and depression have led to an increase in mental disorders to 1.2 billion cases

The number of people with mental disorders has almost doubled over the past three decades, a new study has found. An estimated 1.2 billion people suffered from mental disorders in 2023, according to an analysis recently published in the medical journal The Lancet as part of the Global Burden of Disease 2023 project. Compared to 1990, this figure increased by 95%. The number of cases of major depressive disorder and anxiety disorders increased particularly sharply – by 131% and 158%, respectively. Today, these diseases are considered the most common mental disorders in the world.

The report’s authors emphasize that mental disorders cause serious suffering and lead to long-term loss of health. The consequences affect not only patients themselves, but also families, employers and government systems. Mental illness is associated with decreased productivity, reduced participation in work life and increased pressure on social and health services.

The study also found that mental disorders are more common among women than men. There have been about 620 million cases in women, compared to 552 million in men. Researchers note that this may be influenced by lower self-esteem, increased pressure about appearance, and higher rates of domestic and sexual violence. Hormonal and biological changes, especially during the perinatal period, occupational strain and gender inequality may play an additional role.

Among women, depression and anxiety disorders were most common, as were chronic depression, bipolar disorder, anorexia and bulimia. In contrast, men were more likely to be diagnosed with neurodevelopmental and behavioral disorders, including ADHD, autism and conduct disorders.

The greatest burden on health care systems was observed among adolescents 15-19 years old, which, according to the authors, emphasizes the need for early prevention and enhanced support for young people. Researchers identified childhood sexual abuse, partner violence and bullying as key risk factors. These circumstances are associated with an increased risk of developing depression, anxiety disorders, schizophrenia, bipolar disorder, bulimia and conduct disorders.
