Study Finds Harmful Effects of Chronic Pain Persist Throughout Life

By Pat Anson, PNN Editor

If you have chronic pain in middle age, chances are you will continue to have pain and poor overall health as you enter your senior years, according to a large new study in the UK that found pain has wide-ranging effects throughout life. Pain sufferers are significantly more likely to be unhappy, depressed and unemployed as they grow older.  

Researchers followed the health data and survey responses of over 12,000 people who were born in England, Scotland and Wales in March 1958. The study began in 2003, when most of the respondents were age 44, and continued until they turned 62 in 2021

The research findings, published in PLOS ONE, show that pain can persist for decades and may even be passed from one generation to the next.

“Tracking a birth cohort across their life-course we find chronic pain is highly persistent. It is associated with poor mental health outcomes later in life including depression, as well as leading to poorer general health and joblessness. We hope the study highlights the need for academics and policy makers to focus more attention on the problems of chronic pain,” wrote lead author Alex Bryson, PhD, a Research Fellow at University College London.

Bryson and his colleagues found that two-fifths of respondents reported suffering from chronic pain in their 40’s. Of those, 84% still reported “very severe” pain at age 50. Having chronic pain at 44 was also associated with poor mental health, lower life satisfaction, pessimism about the future, poor sleep and joblessness at age 55.

In the last year of their study, researchers found that having pain at midlife also raises the risk of a covid infection at age 62, a finding that supports previous studies showing that people in poor health are more susceptible to Covid-19.

The study pinpointed several factors that predict pain at a later age, including a father’s social and economic status. Respondents whose fathers were professionals, managers or administrators when they were born were significantly less likely to report chronic pain 44 years later.

The UK study reached many of the same conclusions as U.S. researchers, who have found that less-educated, working class Americans have higher rates of pain, social isolation, drug abuse, disability and suicide than those with college degrees. Efforts at treating physical pain, either with opioids or non-opioid therapies, have failed to turn the tide.  

“Our evidence on the persistence of pain across the life-course suggests efforts to counter it have not been wholly successful,” said Bryson. “We have shown that it is, in part, passed from one generation to the next, with those from lower social classes suffering most. Pain appears to be another source of inter-generational disadvantage, and one that is potentially as problematic as other aspects of social deprivation.”

The Real Reasons People Become Addicted

By Dr. Lynn Webster, PNN Columnist

The Atlantic recently published an article, “The True Cause of the Opioid Epidemic,” that shares an underreported view of the complexities of the opioid crisis. The article acknowledges the epidemic is a multi-faceted drug problem that is largely driven by economic despair.

Yet most of the media remains focused on the large volume of opioids being prescribed, while ignoring the fact that opioids fill a demand created by deeply rooted, unaddressed societal problems.

As PNN reported, a recent study found that auto plant closures in the Midwest and Southeast created a depressed economic environment where drug abuse thrived. Poverty and hopelessness, more than overprescribing, were the seeds of the opioid crisis.

But those factors are only part of the issue. The prevalence of mental health disorders, the lack of immediate access to affordable treatment of addiction, and inadequately treated chronic pain — along with poverty and despair — have caused and sustained the continuing drug crisis.

One of the challenges in beginning to solve the crisis is to change how we view people with the disease of addiction. Rather than provide them with access to affordable healthcare, we stigmatize and criminalize them. This creates recidivism rather than rehabilitation. It affects people who use drugs for the wrong reasons, as well as people who use opioids for severe chronic pain.

Debunking Myths About Addiction

Many people make another false assumption. They claim that opioid addiction develops solely because of exposure to the drugs. That is untrue. Genetic and environmental factors determine who will become addicted. Exposure to an opioid — or any drug of abuse — is necessary for the expression of the disease, but by itself it is insufficient to cause it.

Most Americans are exposed to opioid medication at some point in their lives. In fact, the average person experiences a total of nine surgical and non-surgical procedures in a lifetime. An opioid analgesic is administered during most of these procedures and is often prescribed afterward for pain control. The lifetime risk for developing an opioid addiction is less than one percent of the population.

If exposure alone were responsible for addiction, then the 50 million Americans who undergo an operation every year, or those who undergo nine procedures in a lifetime, would develop an addiction.

Commonly, people who investigate and discuss opioid overdoses believe the deaths are exclusively due to the disease of addiction. But here again, they are mistaken.

An estimated 30 percent or more of overdoses are believed to be suicides. Why do some people choose to intentionally overdose? One driver is the despair that develops from inadequately treated pain. People in pain are almost three times as likely as the general population to commit suicide. They often use drugs rather than violent acts to end their lives.

In addition, efforts to curb opioid prescribing have pushed many people to the streets to purchase illegal and more lethal drugs. This is even true for people without a substance abuse disorder who are seeking pain relief.

Despite a more than 30 percent decline in opioid prescriptions over the past decade, there has been a continued surge in drug overdose deaths. We are seeing a shift in the reasons why people are dying from overdoses. Since 2018, the number of overdose deaths from methamphetamines has exceeded the number of deaths from prescription opioids. This underscores the fact that the problem is less about the supply of opioids and more about the demand for relief of psychological or physical pain.

Clearly, America’s drug crisis involves more than just the overprescribing of opioids — and this helps explain why interventions to reduce prescriptions have not succeeded. Understanding the actual causes of the problem may help us find real solutions. It also would change the focus from people in pain who find more benefit than harm in opioids to those who clearly are at risk of harm from them.

Research Links Auto Plant Closures to Opioid Overdoses

By Pat Anson, PNN Editor

A new study is adding to the growing body of evidence linking the opioid crisis to unemployment, depression, suicide and declining economic opportunities – the so-called epidemic of despair.

Researchers at the Perelman School of Medicine at the University of Pennsylvania and Massachusetts General Hospital looked at the closure of automotive assembly plants in the U.S from 1999 to 2016, primarily in the Midwest and Southeast. They found that opioid overdoses rose significantly in 29 counties where an auto plant shutdown.

Five years after the plants closed, opioid overdose rates among adults were 85 percent higher in counties where closures occurred compared to 83 counties where plants remained open.

"Major economic events, such as plant closures, can affect a person's view of how their life might be in the future. These changes can have a profound effect on a person's mental well-being, and could consequently influence the risk of substance use," said lead author Atheendar Venkataramani, MD, an assistant professor of Medical Ethics and Health Policy.

"Our findings confirm the general intuition that declining economic opportunity may have played a significant role in driving the opioid crisis."

The findings are published in JAMA Internal Medicine.

The demographic group with the biggest increase in opioid overdose deaths after an auto plant closure was non-Hispanic white men between 18-34 years old, followed by non-Hispanic white men ages 35-65 years old. Opioid overdose rates also increased among young non-Hispanic white women.

Death rates involving heroin and other illicit opioids were higher for young white men and women than for prescription opioids, while older white men were more likely to die from prescription opioids.

"While we as clinicians recognize and take very seriously the issue of overprescribing, our study reinforces that addressing the opioid overdose crisis in a meaningful way requires concurrent and complimentary approaches to diagnosing and treating substance use disorders in regions of the countries hardest hit by structural economic change," Venkataramani said.

“Our findings should not be interpreted in such a way as to diminish the role of opioid supply, either from physician prescriptions or from illicitly made and supplied synthetic substances, in the US opioid overdose crisis.”

Princeton researchers Anne Case and Angus Deaton were the first to suggest in 2015 that the declining life expectancy of Americans was not caused by drug abuse alone, but linked to unemployment, poor finances, lack of education, divorce, depression and loss of social connections. They estimate that nearly half a million white Americans died due to a quiet epidemic of pain, suicide, alcohol abuse and opioid overdoses.

The epidemic of despair has also been cited as one of the reasons for the election of Donald Trump and for a “syndemic” of overdoses occurring in counties where the opioid crisis first erupted, particularly in mid-sized cities in Kentucky, Ohio and West Virginia.
