A third of obese adults have arthritis. A new CDC study shows that arthritis may be an unrecognized barrier for obese adults attempting to manage their condition through physical activity. Adults with obesity and arthritis were 44% more likely to be physically inactive compared with obese adults without arthritis. Read more in the MMWR and Spotlight.
More than half of adults with heart disease have arthritis. A CDC study shows that arthritis may be an unrecognized barrier for adults with heart disease attempting to manage their condition through physical activity; 29% of people with both conditions are physically inactive compared to 21% with heart disease alone. Read more in the MMWR and Spotlight and CDC Feature.
More than half of adults with diagnosed diabetes also have arthritis. A recent study found that 30% of adults with arthritis and diabetes were physically inactive, compared with 21% of people with diabetes alone. Among people with diabetes, the high frequency of arthritis appears to be an under recognized barrier to increasing physical activity, a recommended diabetes intervention. Engaging in joint friendly activities; such as, walking, swimming, biking, and participating in available arthritis-specific exercise interventions can help manage both conditions. Read more.
