Statin Use Increases Odds of Back Disorder: Cohort Study by Marlene Busko – May 08, 2017
The researchers retrieved data from 60,455 individuals who were at least 30 years old, lived in the San Antonio area, and were enrolled in the TRICARE health insurance system from 2003 to 2012.
Of these, 17% were active military personnel and the rest were family members and veterans.
In a large observational study of insured individuals in the military and their family members, statin use was associated with increased odds of having a back disorder, including spondylosis, intervertebral disc disorders, herniated discs, and spinal stenosis.
Specifically, for every 17 individuals who were prescribed a statin, one person had a diagnosed back disorder, in this study published online May 1, 2017 as a research letter in JAMA Internal Medicine
“We hope that musculoskeletal adverse events will be part of the patient-provider discussion on the risk/benefit ratio” of these drugs.
About one in six individuals (10,910) had been prescribed a statin, usually simvastatin (in 72% of prescriptions), and on average, they had been taking this drug for 3.7 years.
“We are not advocating for taking patients off statins if they have cardiovascular risk factors. As clinicians we should be aware of these potential associations and understand the spectrum of potential adverse effects.”
“Our results provide additional motivation to further investigate the overall influence of statin therapy on musculoskeletal health, specifically if prescribed for primary prevention in physically active individuals,” the researchers summarize.
Can Statins Cause Back Pain?
Close to a third (30%) had a back disorder.
Two previous studies based on NHANES data reported that statin use was associated with musculoskeletal pain including back pain among individuals without arthritis
being prescribed a statin (as opposed to not being prescribed this drug) significantly raised the odds of having a back disorder (odds ratio 1.27; 95% CI 1.19–1.36).
In the overall cohort and in prespecified subgroups (such as nonobese individuals, healthy individuals, or those without musculoskeletal conditions at baseline, statin use was consistently associated with increased odds of being diagnosed with a back disorder.
In an analysis of the overall cohort, but with adjustment for propensity scores, the risk increase for a back disorder went from 30% among statin users to 47% among those taking high-intensity statins.
It also increased with duration to as high as 59% with >4 years of use.
This makes me very wary of statins – I don’t think I’d take them unless there was a very, very good reason.
