May 8, 2008 -- More than half of people with diabetes also suffer arthritis, CDC researchers find.
It's not just a problem for older people. Diabetes patients aged 18 to 44 have a 27.6% chance of having arthritis -- 2.5 times the 11% rate seen in the general population.
Double Trouble - Arthritis & Diabetes
Lots of research focuses on a single medical condition, but many people have
more than one ailment. So a logical question is: How do these conditions affect
People with both diabetes and arthritis face special barriers to being
physically active, such as worry about aggravating or causing further joint
damage, and uncertainty about which activities are safe.
In the 45-64 age group, arthritis strikes 51.8% of people with diabetes and 36.4% of the general population. Arthritis afflicts 62.4% of diabetes patients 65 and older, vs. 56.2% of those without diabetes. The findings come from nationwide telephone surveys conducted in 2005 and 2007.
The extent of the problem surprised the research team, says Charles Helmick, MD, lead scientist for the CDC's arthritis program.
"We expected there would be these differences [in arthritis prevalence] among older people, but there were very strong differences among younger people, too," Helmick tells WebMD. "A lot of them had both arthritis and diabetes -- as well as physical activity levels that were not very high."
That's the crux of the issue. Exercise is particularly important for people with diabetes. It's also extremely important for people with arthritis. Yet the CDC study shows that when people with diabetes have arthritis, they are much less likely to get the exercise they need to prevent both diseases from getting worse.
People with diabetes don't always exercise as much as they should. More than 20% of people with diabetes are inactive. But 30% of people with both diabetes and arthritis are inactive.
What's going on? Arthritis gives people with diabetes a new reason to exercise. But it also creates new barriers to physical activity, Helmick says.
"In diabetes, we speculate, everybody has the usual barriers for not being physically active: not having time, competing priorities, lack of motivation, and so on," he says. "But when you have arthritis you have special barriers on top of those. You don't know what activities are safe. And you worry: 'Will exercise make my joint pain worse?' 'Will exercise harm my joints?'"
