Anxiety Statistics, Facts, & Resources

People with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations. Often, anxiety disorders involve repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes, also called panic attacks.¹

There is no one cause of anxiety. Events, fears, everyday situations, and even genetics play a role and can trigger anxiety disorders. There are various types of anxiety disorders including social, generalized, panic disorders, Post-Traumatic Stress Disorder (PTSD), and specific anxiety disorders. Understanding risk factors as well as signs and symptoms can help identify and treat them.

The symptoms and diagnostic criteria for each subset of anxiety disorders are unique. However, collectively, the WHO’s International Classification of Diseases (ICD-10) note frequent symptoms of:

• “Apprehension (worries about future misfortunes, feeling “on edge,” difficulty in concentrating, etc.)
• Motor tension (restless fidgeting, tension headaches, trembling, inability to relax)
• Autonomic overactivity (lightheadedness, sweating, tachycardia or tachypnoea, epigastric discomfort, dizziness, dry mouth, etc.).”

Signs of anxiety manifest differently in everyone, other common symptoms one can experience are:

• Feeling nervous, restless or tense

Anxiety & Co-Occurring Disorders

Prolonged anxiety places extra stress on the body. Therefore, chronic stress and anxiety disorders are often associated with another physical illness, or co-occurring disorder, which can in turn create a feedback loop making symptoms worse. A common co-occurring disorder of anxiety is substance abuse.

Anxiety disorders co-occur with substance use disorders at a high rate in both the general population and in people seeking treatment for addiction. Studies also show the co-occurrence of these disorders is associated with more severe symptoms relative to either disorder alone.⁸

Additionally, patients who have been diagnosed with serious, chronic, or terminal illnesses often have difficulty coping and can experience psychological symptoms. These symptoms can manifest as mania, depression, insomnia, and anxiety attacks. Statistics show that after diagnosis, 40% of cancer patients report developing significant distress that can include serious worry, panic attacks, depression, and PTSD, or posttraumatic stress disorder.⁹

Other common co-occurring disorders are:

• Irritable bowel syndrome (IBS)
  • Research has found that 50-90% of patients with IBS have a psychiatric disorder such as an anxiety disorder or depression¹⁰
• Headaches¹¹
  • Migraine headaches can precede the onset of mental disorders, according to a 2009 study
  • A study found that 11% of participants in the study had migraines and a variety of anxiety or depressive disorders
• Eating disorders
• Hoarding disorder
• Sleep disorders
• Adult ADHD (attention deficit/hyperactivity disorder)
• Chronic pain
• Fibromyalgia

As with all illnesses and disorders, it’s important to find appropriate treatment early.

Risk Factors for Anxiety Disorders

Anxiety occurs in people for different reasons ranging from everyday stressful situations, traumatic events like the death of a loved one, sleep disorders, or even genetics. Increased use in social media use has even been cited as a potential factor as to why anxiety prevalence has risen over the years. One study revealed that more time spent using social media was significantly associated with greater symptoms of dispositional anxiety.¹²

Other risk factors include:

• Children and adults experiencing traumatic events are at a higher risk of developing an anxiety disorder
• Low self-esteem, particularly in young people, can indicate anxiety¹³
• Genetics play a factor: One study found there is a moderate genetic risk of anxiety with a heritability of 30%¹⁴
• Major depressive disorder and other mental health disorders may often co-occur with anxiety
• Substance abuse, including drug or alcohol use, can increase or worsen anxiety

Anxiety Disorder Rates by Socioeconomic Status

Income level, education, and socioeconomic status affects whether a person is able or likely to seek help from a professional for mental health and mental disorders. For each additional level of education:¹⁵

• Individuals were 15% more likely to see a psychiatrist
• 12% more likely to see a family doctor
• 16% more likely to see a psychologist
• 16% more likely to see a social worker

Anxiety Within Minority Groups

Anxiety disorders do not affect all races and ethnicities equally. Studies show that different disorders are more prevalent amongst certain races, with different rates across ethnicities and types of anxieties.

One study found that white Americans demonstrate more symptoms of anxiety disorders than minority groups, with the exception of Post-Traumatic Stress Disorder (PTSD). PTSD trends show that this particular anxiety disorder is more common among African Americans.

The study also found that different rates of anxiety disorders varied based upon races. The results showed the prevalence among different races for social anxiety disorder:¹⁶

• White Americans: 12.6%
• African Americans: 8.6%
• Hispanic Americans: 8.2%
• Asian Americans: 5.3%

For generalized anxiety disorder, the prevalence was:

• White Americans: 8.6%
• Hispanics: 5.8%
• African Americans: 4.9%
• Asian Americans: 2.4%

Prevalence of panic disorder among different races was found to be:

• White Americans: 5.1%
• Hispanic Americans: 4.1%
• African Americans: 3.8%
• Asian Americans: 2.1%

PTSD prevalence was:

• African Americans: 8.6%
• White Americans: 6.5%
• Hispanic Americans: 5.6%
• Asian Americans: 1.6%

Anxiety Disorder Statistics by Sexual Orientation & Gender Identity

Statistics around sexual orientation and mental health are difficult to quantify, but the studies that have been conducted point to mental health disparities among some, but not all, sexual minority groups. Researchers emphasized the importance of including multiple measures of sexual orientation in population-based health studies.

One study found that mental health outcomes differed by sex, dimension of sexual orientation, and sexual minority group. Whereas a lesbian, gay, or bisexual identity was associated with higher odds of any mood or anxiety disorder for both men and women, women reporting only same-sex sexual partners in their lifetime had the lowest rates of most disorders.¹⁷ The same study revealed:¹⁷

• Higher odds of any lifetime mood or anxiety disorder were more consistent and pronounced among sexual minority men than among sexual minority women
• Bisexual behavior conferred the highest odds of any mood or anxiety disorder for both males and females.

An additional study showed that sexual minority groups when compared to heterosexual respondents were significantly more likely to describe their lives as stressful, with a weak sense of belonging in their community. Researchers concluded that factors placed them at significantly greater odds of the negative mental health outcomes.¹⁹

A review of multiple studies concluded that:

• Consistent pattern of lowest rates of anxiety among heterosexual people¹⁸
• Bisexual people exhibt higher or equivalent rates in comparison to lesbian and gay people¹⁸/li>
