“People with arthritis are not meeting physical activity recommendations made at the federal level and by experts in the arthritis field,” said co-author Jennifer Hootman, Ph.D., of the Centers for Disease Control and Prevention. “That’s not good, because we know that being more active is beneficial for arthritis.”

While exercise has been shown to decrease their pain, delay disability and improve gait and function, people with arthritis are even more likely to be inactive than adults in the general population.

Hootman and colleagues reviewed data from the 2002 National Health Interview Survey, an ongoing household survey designed to be representative of the U.S. population. The survey included 6,829 people who had been diagnosed with arthritis and 20,676 people without arthritis.

Just 37 percent of adults with arthritis met the least stringent physical activity guidelines established by a panel of experts in arthritis, physical activity and public health in 2001 — a percentage similar to people without arthritis.

But participation rates at the more rigorous federally recommended levels of physical activity were even lower for people with arthritis — 30 percent compared with 33 percent for people without arthritis.

“We can’t tell from this survey which came first—the inactivity or the problems with function,” said Hootman. “But we do know that getting people with arthritis active actually improves function.”

The authors say that fear of pain and the misconception that exercise can harm joints are obstacles to getting people with arthritis to exercise.

“If we can get people with arthritis over the initial pain barrier by addressing their pain and getting them more active, they’ll actually have less pain in the long term,” Hootman said.
