It’s no secret that middle-aged women are far more likely than men to have chronic pain and to feel its effects more severely. A large new study tells us some of the reasons why.

VA researchers analyzed the health data of over 200,000 female veterans between the ages of 45 and 64 and found that women with menopause symptoms were nearly twice as likely to have chronic pain and multiple chronic pain diagnoses.

"Changing levels of hormones around menopause have complex interactions with pain modulation and pain sensitivity, which may be associated with vulnerability to either the development or exacerbation of pain conditions," says JoAnn Pinkerton, MD, Executive Director of the North American Menopause Society (NAMS). "This study suggests that menopause symptom burden may also be related to chronic pain experience."

Hormonal change alone wasn’t the only thing many of the women had in common. Those who were overweight, obese or had a mental health diagnosis were also more likely to have chronic pain. Eighteen percent of the female veterans had been diagnosed with post-traumatic stress disorder (PTSD), 13 percent suffered from depression and 15 percent had anxiety.

Common changes related to menopause and aging include weight gain, decreased physical activity, impaired sleep and negative mood, which can contribute to chronic pain and are also known to affect pain sensitivity and tolerance.

“Both chronic pain and menopause symptoms are strongly and consistently associated with psychosocial factors and health risk behaviors prevalent in and after the menopause transition,” said lead author Carolyn Gibson, PhD, San Francisco VA Health Care System. “Consideration should be given to integrated approaches to comprehensive care for midlife and older women with chronic pain, such as targeted cognitive behavioral therapy coordinated with interdisciplinary care providers.”    

The study findings are published in the journal Menopause.

A large 2018 study also found a strong association between menopause and symptoms of rheumatoid arthritis (RA). Researchers at the University of Nebraska Medical Center found that post-menopausal women with RA had a significant increase in functional physical decline. Menopause was also associated with worsening progression of the disease.
