Childhood Trauma Raises Risk of Chronic Pain in Adults by 45%

By Pat Anson, PNN Editor

People who experienced neglect or physical, sexual or emotional abuse as children are significantly more likely to have chronic pain as adults, according to a large new analysis. Individuals who had adverse childhood experiences (ACEs) were 45% more likely to report chronic pain in adulthood than those who did not have childhood trauma.

“These results are extremely concerning, particularly as over 1 billion children – half of the global child population – are exposed to ACEs each year, putting them at increased risk of chronic pain and disability later in life,” says lead author André Bussières, PhD, an Assistant Professor at the School of Physical & Occupational Therapy at McGill University. 
 
“There is an urgent need to develop targeted interventions and support systems to break the cycle of adversity and improve long-term health outcomes for those individuals who have been exposed to childhood trauma.”  

Bussières and his colleagues reviewed 75 years of research involving over 826,000 people. Their findings, published in the peer-reviewed journal European Journal of Psychotraumatology, adds to the growing body of evidence showing an association between ACEs and chronic pain.

ACEs may affect a child directly through physical, sexual or emotional abuse, or neglect – or indirectly through exposure to environmental factors like domestic violence, living with substance abuse, or parental loss.

Physical abuse during childhood had the strongest association with chronic pain and pain-related disability. The odds of having chronic pain were also higher if a person experienced multiple ACEs, either alone or combination with indirect ACEs. The research does not prove that ACEs cause chronic pain, only that there’s an association.

“Our findings suggest ACE exposure is associated with the most common and costly chronic pain conditions, including back and neck pain and other MSDs (musculoskeletal disorders), which account for the highest total health care spending compared to other health conditions,” researchers said.

“People with ACEs tend to have a higher chronic disease burden, barriers to treatment engagement, and greater health care utilization in adulthood. Adult patients exposed to ACEs may not be achieving optimal health outcomes due to the physiological and psychological effects of toxic stress. While the relative contributions of these mechanisms are not yet well understood, emerging evidence links ACEs to changes in genetic expressions that affect structural and functional changes in the brain and clinical phenomena in adulthood.”

Still unclear is the role that ACEs play in specific pain-related conditions. Previous studies have linked childhood trauma to an increased risk of headache disorders, fibromyalgia and lupus, as well as mood and sleep problems.

Childhood Trauma and Neglect Increase Risk of Headache Disorders

People who experience traumatic events during childhood, such as physical abuse, sexual abuse or neglect, are more likely to have headache disorders as adults, according to a large new study. The research adds to a growing body of evidence linking adverse childhood experiences (ACEs) to headaches and migraines in adults.

“Traumatic events in childhood can have serious health implications later in life,” says lead author Catherine Kreatsoulas, PhD, of Harvard T.H. Chan School of Public Health. “Our meta-analysis confirms that childhood traumatic events are important risk factors for headache disorders in adulthood, including migraine, tension headaches, cluster headaches, and chronic or severe headaches. This is a risk factor that we cannot ignore.”

Kreatsoulas and her colleagues reviewed 28 studies that examined the childhood histories of nearly 155,000 people in 19 countries. Their findings are published Neurology, the medical journal of the American Academy of Neurology.

About a third of the participants (31%) reported at least one traumatic childhood event. Of those, 26% were diagnosed with a primary headache disorder, compared to 12% of participants who said they experienced no childhood trauma. People who had four or more traumatic events during childhood were more than twice as likely to have a headache disorder than those who had one ACE.

Researchers also examined different types of childhood trauma. Events categorized as “threat” traumas included physical abuse, sexual abuse, emotional abuse, witnessing or being threatened with violence, and serious family conflicts.

Events categorized as “deprivation” traumas included childhood neglect, economic adversity, divorce or separation, parental death, alcohol or substance abuse, and living in a household where someone has a mental illness, chronic illness, disability or is incarcerated.

Threat traumas were linked to a 46% increase in headache disorders, while deprivation traumas were linked to a 35% increase in headaches. Among threat traumas, physical and sexual abuse were associated with a 60% increased risk for headaches. Among deprivation traumas, neglect was linked to a nearly three-fold increased risk for headache disorders.

“Threat or deprivation traumas are important and independent risk factors for headache disorders in adulthood,” said Kreatsoulas. “Identifying the specific types of childhood experiences may help guide prevention and treatment strategies for one of the leading disabling disorders worldwide. A comprehensive public health plan and clinical intervention strategies are needed to address these underlying traumatic childhood events.”

Due to the stigma and sensitive nature of childhood trauma, researchers say it’s likely the number of ACE cases is under-reported by adults.

 “Despite this, the robustness of these findings cannot be underappreciated as the studies composing this meta-analysis represent diverse global regions and the findings supersede cultural contexts,” they said.

The research does not prove that ACEs cause headaches -- it only shows an association.

Previous studies have also linked childhood trauma to an increased risk of chronic pain conditions such as fibromyalgia and lupus, as well as mood and sleep problems.

Does Childhood Trauma Increase Risk for Opioid Misuse?

By Pat Anson, PNN Editor

Did a parent humiliate or swear at you as a child? Were you ever molested? Did you live with a problem drinker or someone who went to prison? Were your parents ever separated or divorced?

Those are some of the questions posed to over 1,400 college students in a study by researchers at the University of Georgia, who wanted to assess the relationship between childhood trauma and the misuse of prescription opioids later in life.

Their research, recently published in the Journal of American College Health, found that most students had at least one adverse childhood experience (ACE). But those who reported four or more ACEs were almost three times more likely to misuse opioid medication.

Based on that finding, the researchers say healthcare providers should consider a patient’s experience with childhood trauma before prescribing them opioids.

“Our findings suggest need to include assessment of ACEs as a screening criterion for opioid prescription and administration among college-aged individuals,” wrote lead author Janani Thapa, PhD, an associate professor in UGA’s College of Public Health.

Many doctors already use screening tools to assess whether a patient is at risk for opioid misuse. They look up their prescription drug history, or ask patients if they’ve been sexually abused or have family members with a substance use disorder.

But Thapa and her colleagues think that assessment should go further, incorporating a wider range of childhood trauma, such as whether a patient didn’t have enough to eat or had to wear dirty clothes as a child.  

“Prevention of opioid misuse demands careful consideration of the traumatic exposure of the patient,” they said. “Current opioid assessment measures, including patient or family interviews, and prescription monitoring, may need to incorporate patients’ traumatic history for proper chronic pain management and integrated care.”

Penalizing Patients

The use of opioid screening tools is controversial. Some patients resent being asked about their childhood trauma – which they see as irrelevant to their health problems and pain management as adults.   

“I overcame my early life abuse until an ignorant doctor used that childhood abuse without psychiatric consultation to put labels on me and refuse medicine for pain,” one patient told us.

“Just because a patient may have been sexually abused or has family members who are addicts/alcoholics, does not mean the patient will be,” said another. “To penalize a person who is in excruciating pain due to no choice of their own, is cruel and inhumane.”

But a pain management expert says opioid screening tools have their place, because childhood trauma can have a lasting impact. 

“Most studies have shown that 4 in 5 people with an Opioid Use Disorder have at least one ACE,” says Lynn Webster, MD, past president of the American Academy of Pain Management and a PNN contributor. “I consider ACEs a form of post-traumatic stress disorder. It affects emotion regulation, causing an inability to modulate distressing emotions in a healthy and adaptive way. ACEs create a maladaptive response to stress. The earlier in life the ACEs occur, the more effect they will have later in life.” 

Over 20 years ago, Webster developed one of the first opioid screening tools for doctors, a short survey that asked patients if they had a history of substance abuse, sexual abuse, or any mental health issues. In his own practice, Webster found the survey helpful in identifying patients at risk of abusing opioids, but he later came to regret how the screening tool was “weaponized” against patients, particularly women, and used by other doctors as an excuse to deny patients opioids. 

“The Opioid Risk Tool (ORT) incorporates pre-adolescent trauma to help identify females who were at greater risk of OUD from what I believe is a form of PTSD. If I were to develop the tool today, I would probably make it gender neutral, but the increased risks for females would remain,” Webster said in an email. 

Webster agrees with the University of Georgia researchers that ACEs should be used to help assess whether a patient is at risk of abusing medication. But he says a high number of ACEs should not be used to avoid prescribing opioids to someone who has a medical need for them.
