A comprehensive analysis of over 375 published studies has revealed a striking connection between chronic pain and elevated rates of depression and anxiety, underscoring a critical public health issue. Led by researchers from Johns Hopkins Medicine, the study found that 40% of adults living with chronic pain suffer from clinically significant depression and anxiety, with women, younger adults, and those diagnosed with fibromyalgia being most at risk.
For decades, scientific research has highlighted the correlation between pain and mood disorders. However, the new findings, published on March 7 in JAMA Network Open, indicate that the co-occurrence of chronic pain with mental health issues is more widespread than previously understood, calling for routine screenings, improved access to specialized care, and the development of integrated treatment options.
Chronic pain, defined as lasting for more than three months, is a debilitating condition that affects millions. The Centers for Disease Control and Prevention (CDC) reports that 20.9% of U.S. adults—an estimated 51.6 million people—experienced chronic pain in 2021. Among these individuals, between 20% and 40% also struggle with depression and anxiety, according to prior research.
“Currently, we have effective psychological treatments for both chronic pain and mood disorders, but they are often treated separately,” said Rachel Aaron, Ph.D., the study’s lead author and assistant professor at the Johns Hopkins University School of Medicine. “Many clinical trials exclude patients with both chronic pain and mental health conditions, which highlights the need for integrated treatment approaches that address both issues simultaneously.”
The research team analyzed data from 376 studies, involving over 347,000 patients across 50 countries. The goal was to estimate the prevalence of depression and anxiety among individuals with chronic pain. Their findings revealed that chronic pain patients are significantly more likely to experience clinical symptoms of both depression (39%) and anxiety (40%) compared to those without chronic pain. However, the rates of diagnosed conditions such as major depressive disorder and generalized anxiety disorder were somewhat lower, with major depressive disorder affecting 37% and generalized anxiety disorder 17%.
The study also revealed a critical insight: elevated levels of depression and anxiety may be specifically associated with chronic pain itself, rather than simply being a byproduct of having any medical condition. Furthermore, the research pointed to psychological distress and adverse life experiences as key risk factors for developing chronic nociplastic pain, a type of pain caused by alterations in how pain signals are processed in the brain and spinal cord.
These findings further emphasize the importance of addressing both chronic pain and its psychological impact. Currently, clinical settings where chronic pain is treated often lack consistent screening for depression and anxiety, leading to missed opportunities for intervention. Researchers advocate for a shift in how chronic pain patients are treated, with a focus on integrated care that combines pain management with mental health support.
Despite these challenges, Aaron also highlighted the resilience of many individuals living with chronic pain. “Most people with chronic pain do not have depression or anxiety,” she noted. “These findings challenge the narrative that chronic pain automatically leads to depression and remind us that many individuals with chronic pain lead fulfilling, psychologically healthy lives.”
As the study makes clear, the need for more comprehensive care and innovative treatments has never been more urgent, aiming to improve both the physical and mental well-being of individuals suffering from chronic pain.
