Obesity Appears Linked to Pain

FRIDAY, Feb. 10 (HealthDay News) — There’s a clear link between
obesity and pain, suggests a new study that finds the heaviest people
suffer the greatest discomfort.

Researchers examined data from more than 1 million people who were
asked about their health, pain and well-being in telephone surveys
conducted between 2008 and 2010. Thirty-eight percent of the participants
were overweight and 25 percent were obese. Those who were obese were
classified into one of three obesity levels as defined by the World Health
Organization.

Compared to people with low to normal weight, pain rates were 20
percent higher for overweight people, 68 percent higher for those in the
Obese 1 group, 136 percent higher for the Obese 2 group, and 254 percent
higher for the Obese 3 group.

The researchers also found that as people age, excess weight is
associated with even higher levels of pain.

The study was published recently in the online edition of the journal
Obesity.

“Our findings confirm and extend earlier studies about the link between
obesity and pain. These findings hold true after we accounted for several
common pain conditions and across gender and age,” Arthur Stone, vice
chair of the department of psychiatry and behavioral science at Stony
Brook University School of Medicine, said in a university news
release.

“We wanted to explore this relationship further by checking to see if
it was due to painful diseases that cause reduced activity, which in turn
causes increased weight,” Joan Broderick, an associate professor in Stony
Brook’s Department of Psychiatry and Behavioral Science and School of
Public Health, said in the news release.

“We found that ‘pain yesterday’ was definitely more common among people
with diseases that cause bodily pain. Even so, when we controlled for
these specific diseases, the weight-pain relationship held up. This
finding suggests that obesity alone may cause pain, aside from the
presence of painful diseases,” she said.

Musculoskeletal pain was the source of some of the pain, according to
the report, but it wasn’t the only cause.

Researchers say there are other possible explanations why many obese
people suffer from pain, including that the excess fat may trigger
processes that result in inflammation and pain. Depression is another
possibility.

More research into the pain-obesity connection is needed, they
said.
