The researchers found that women, young adults and people with other medical conditions were at higher risk for anxiety disorders.
In particular, researchers say women are almost twice as likely to be affected as men. This difference does not change with time.
The aim of the review is to determine the prevalence of anxiety disorders in both the general public and among specific groups of people.
“Anxiety disorders can make life very difficult for some people and it is important for our health services to understand how common they are and what groups of people are most at risk,” explains first author Olivia Remes University Cambridge in the United Kingdom.
According to Centers for Disease Control and Prevention (CDC), anxiety disorders are the most common type of mental disorders present in the general population. Examples of anxiety disorders include PTSD social anxiety disorder obsessive-compulsive disorder (TOC), and.
The CDC estimates that the prevalence of anxiety disorders is more than 15 percent .
Typical symptoms of anxiety disorders include increasing worry, tension, tired , and fear. These symptoms can prevent people keep their daily routines. The study authors point out that the annual cost of these disorders in the United States is estimated at $ 42.3 million.
Many reviews Most scientists have examined the effects of depression that the effects of anxiety, despite this impact on society. The new review, published in Brain and Behavior , aims to shed more light on this area of research.
The team, led by University of Cambridge, examined the results of 48 reviews of studies of anxiety. These revisions included in the development of anxiety, anxiety about addiction , and anxiety along with other conditions such as cancer and heart disease .
Criticism also saw anxiety in different configurations – both clinically and in the community – and in different locations around the world.
Rates of anxiety almost equal to 1990-2010
About 4 out of every 100 people in general were reported to experience anxiety. Anxiety rates were highest in North America (8 100) and lowest in East Asia (less than 3 out of 100). These proportions remained virtually unchanged from 1990 to 2010.
Groups of people who were most affected by anxiety disorders were women, adults under 35, and people with other health conditions.
About 10.9 percent of adults with cardiovascular disease in Western countries also had generalized anxiety disorder. In addition, about 32 percent of people with Multiple Sclerosis also had an anxiety disorder.
TOC was found to be more common in pregnant women and women who had recently given birth. While about 1 in 100 people in the general population had OCD, the rate was raised in those who had recently given birth and almost double in pregnant women.
“By collecting all this data together, we see that these disorders are common in all groups, but women and young people are affected disproportionately,” says Remes. “Also, people who have a chronic health condition are particularly at risk, adding a double burden on their lives.”
The authors acknowledge that while anxiety disorders is an area of growing interest, there are some limitations to existing research. In particular, marginalized groups are under-represented in the views of researchers consulted.
While anxiety disorders are a major problem among people who identify as lesbian, gay or bisexual (LGB), for example, only one of 48 reviews looked LGB groups.
Professor Carol Brayne, Director of the Cambridge Institute of Public Health, expands on this problem:
“Even with a reasonably large number of studies of anxiety disorder, data on marginalized groups is difficult to find, and these are the people who are likely to be in the general population even greater risk.”
“We hope that by identifying these gaps, future research can be directed towards these groups and include a greater understanding of how these tests can help reduce individual and population burdens” he concludes.
