Statistics of anxiety disorders

Anxiety disorders are a diverse group of basically similar psychological disorders. Anxiety

disorders have the common elements of unusually high levels of fear accompanied by anxiety

and behavioral abnormalities. The Diagnostic and Statistical manual of Mental Disorders in its

fifth edition (denoted as DSM-5) is the most recent publication which provides the definition and

statistics regarding psychological disorders. The DSM-5 considers generalized anxiety disorder

(GAD), panic disorder (PD), social anxiety disorder, phobias and substance-induced anxiety to

belong to the spectrum of anxiety disorders (Emedicine.medscape.com, 2018).

Anxiety disorders have high prevalence among all the psychiatric and mental health disorders.

Anxiety disorders often occur in conjunction with another major psychiatric ailment, depression.

Worldwide, the prevalence of depression was expected to be three hundred million as of year

2015. Approximately similar prevalence of various anxiety disorders also exists. Anxiety and

depression often co-exist so there is an overlapping prevalence of both the disorders. Anxiety

disorders pose a huge burden of disease with respect to disability. Anxiety disorders are ranked

as the sixth largest contributor to worldwide disability standing at 3.4 percent contribution to

global disability. Anxiety disorders resulted in a sum of 24.6 million years lost to disability in

2015 alone (Apps.who.int, 2018).

As per 2015 estimates, 3.6 percent of the people of the world suffer from one or the other form

of an anxiety disorder. Therefore a total of two hundred and sixty four million people living in

the world suffer from anxiety. Anxiety and depression both have higher prevalence in the female

population compared to the male population with 4.6 percent of females suffering from these

disorders compared to 3.6% of the males. Therefore females have nearly double the prevalence

than males. When age groups are compared for prevalence, no significant differences exist

between the different age-groups except for the elderly, who show a relatively lower prevalence.

(Apps.who.int, 2018)

Although yearly data and statistical figures have their own importance, lifetime-prevalence is

considered to be the most significant statistical figure in understanding the impact of the disease.

The twelve months prevalence figures merely suggest the number of people having an anxiety

disorder currently. The probability of people acquiring an anxiety disorder at some point in their

lives is predicted on the basis of past life-time prevalence statistics.

The following is a probability distribution of people acquiring an anxiety disorder at some point

in their lives:

Any of the anxiety disorders

28.8%

Generalized Anxiety Disorder (GAD)

5.7%

Obsessive Compulsive Disorder (OCD)

1.6%

Panic disorder (PD)

4.7%

Social phobia

12.1%

Specific (other) phobia

12.5%
