We couldn’t let the week pass without a look at the findings that arthritis and diabetes are fellow travelers in this country.

swimmerMore than half of Americans diagnosed with diabetes also have arthritis, according to telephone survey data analyzed by researchers at the Centers for Disease Control and Prevention. Arthritis, broadly defined to include rheumatic conditions such as gout and lupus, was more common in diabetics than people without diabetes, regardless of sex or age.

Is there some hidden link between the conditions, we wondered? “We don’t have any evidence that diabetes causes arthritis or that arthritis causes diabetes,” Chad Helmick, medical epidemiologist for the arthritis program at CDC, told the Health Blog. “Arthritis is very common among people with diabetes, even the young,” he noted. “We don’t know why there is an association.”

A health problem uncovered by the work is that 29.8% of people with both conditions were physically inactive compared with just 21% of those with diabetes alone. And the additional inactivity wasn’t explained by differences in sex, age or weight.

Being physically active can help people cope with diabetes and arthritis. Having arthritis pain may discourage some people from exercising. So Helmick suggested exercise that’s easy on the joints, such as swimming or walking. “There are things you can do to make sure you can live your life the way you want to live,” he said, adding, “things that don’t involve taking a lot more medication.”
