Does fatness cause low back pain?
Low back pain is one of the most common health complaints around the world, affecting some 65% of adults at some point in their lives.
Common wisdom suggests that fatter people are more likely to experience low back pain than thinner people, and weight loss is often prescribed to treat or manage low back pain. But does the science actually support these beliefs?
In a word: No.
There is no reliable and consistent evidence that fatter people suffer from lower back pain more than thinner people. For example, in one highly-cited systematic review of 65 epidemiological studies, each with more than 3000 participants, only 30% of the studies observed a weak association between weight and low back pain. Thus, as another review concluded, “the available data at this time is controversial with no clear-cut evidence connecting low back pain with obesity.”
And what about weight loss? I was unable to locate any published randomized and controlled experiments demonstrating that weight loss improves low back pain. Prescribing weight loss to treat low back pain is not evidence-based medicine.
A four-year prospective, longitudinal study of more than 1000 adult Spanish twins who did not have lower back pain at baseline confirmed that fatness does not increase the risk of experiencing chronic low back pain in the future.
