Arthritis and Sedentary Life

A sedentary lifestyle in older adults with arthritis, particularly women and minorities, is associated with declining ability to perform basic functional tasks of daily living, a Northwestern University study has found.

Dorothy D. Dunlop, PhD, and colleagues from the Feinberg School of Medicine and Rehabilitation Institute of Chicago described the findings of their study of more than 5,700 women and men aged 65 and older with arthritis in an article published in the April issue of the journal Arthritis & Rheumatism. Dr. Dunlop is research associate professor in the Northwestern University Institute for Health Services Research and Policy Studies.

The researchers found that lack of regular vigorous physical activity almost doubled an arthritis patient's odds for functional decline and eventual disability in basic daily tasks essential to maintaining independence.

Study data showed that over two years nearly 14 percent of study participants experienced a measurable decline in their ability to carry out higher-level daily activities, such as preparing hot meals, shopping for groceries, making telephone calls, taking medications, and managing money, as well as such basic tasks as walking across a room, dressing, bathing, eating, using the toilet, and transferring from a bed.

The researchers assessed various risk factors, including age, education, income level, and the toll of other adverse health conditions in this group, and took note of potentially unhealthy behaviors, such as smoking, alcohol use, extreme weight gain or loss, and sedentary lifestyle.

Sedentary lifestyle was the most prevalent risk factor, reported by more than 64 percent of study participants.

Functional ability deteriorated more frequently among women (15 percent) than men (11 percent) and substantially more frequently among minorities (18 percent among Hispanics and close to 19 percent among African Americans) than whites (around 13 percent).

The high rates of functional decline among older women and ethnic minorities with arthritis were attributed to the burden of added ailments, particularly diabetes, stroke, vision loss, depression, and cognitive impairment. No alcohol use (moderate drinking was found to have a protective effect) also was a risk factor.
