Anxiety, OCD & Perinatal Mental Health: What the Research Shows

Anxiety disorders, OCD, and perinatal mood and anxiety disorders (PMADs) are common, well-studied conditions with strong evidence behind their treatment. Below is a summary of the current research on prevalence and treatment, with sources, to help you understand what you or a loved one may be experiencing.

Anxiety Disorders

An estimated 19.1% of U.S. adults experience an anxiety disorder in any given year, and 31.1% will experience one at some point in their lifetime, according to the National Institute of Mental Health. Anxiety disorders affect women at a higher rate than men, with a past-year prevalence of 23.4% in women compared to 14.3% in men. Among adults with an anxiety disorder, impairment ranges widely: an estimated 22.8% experience serious impairment, 33.7% experience moderate impairment, and 43.5% experience mild impairment, based on NIMH data.

Specific phobias are the most common type of anxiety disorder, affecting an estimated 9.1% of the population, according to research summarized by the Anxiety and Depression Association of America (ADAA).

Obsessive-Compulsive Disorder (OCD)

OCD affects an estimated 1.2% of the U.S. adult population, or roughly 2.5 million adults, according to the National Institute of Mental Health. Women are affected at roughly three times the rate of men.

Post-Traumatic Stress Disorder (PTSD)

PTSD affects an estimated 3.6% of the U.S. population, with a notable gender gap: an estimated 5.2% of women and 1.8% of men are affected, according to ADAA-cited research.

Perinatal Mood and Anxiety Disorders (PMADs)

Perinatal mood and anxiety disorders are considered the most common complication of pregnancy and childbirth. An estimated 1 in 5 pregnant or postpartum people are diagnosed with a mood or anxiety disorder during the perinatal period, according to research published by the Journal of Obstetric, Gynecologic & Neonatal Nursing citing Postpartum Support International data.

Perinatal anxiety disorders specifically affect an estimated 20.7% of women, according to a systematic review, with a slightly higher prevalence during pregnancy than in the postpartum period. Perinatal depression affects approximately 1 in 7 pregnant people, according to Postpartum Support International.

PMADs remain significantly underdiagnosed and undertreated: research indicates these conditions go undetected in 50% to 70% of cases, and an estimated 85% of affected patients receive no treatment at all.

Why This Matters

These numbers make one thing clear: if you're struggling with anxiety, OCD, PTSD, or a perinatal mood or anxiety disorder, you are far from alone, and these are treatable conditions. Evidence-based approaches — including Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and exposure therapy — are well-supported treatments for these conditions. Yet the data above also shows a persistent treatment gap, particularly for perinatal mental health, which is part of why early, informed support matters.
