Relationship between depression and functional measures in overweight and obese persons with osteoarthritis of the knee

Daniel Possley, DO, et al.

Depression is common in individuals with chronic illness who are overweight and obese. We examined the relationship between depression symptoms, perceived physical function, and physical performance in 105 adults with osteoarthritis of the knee who were overweight and obese. Forty-two percent of the sample was classified as depressed according to the Center for Epidemiologic Studies Depression Scale. A moderate relationship was observed between perceived physical function and physical performance in patients who were not depressed that did not exist in patients reporting depressive symptoms. Poorer function and younger age accounted for 29% of the variance in depressive symptoms.

Researchers Dupret-Bories et al recently tested a titanium tracheal prosthesis in sheep to determine the best surgical implantation method. In time, the prosthesis may serve as a substitute for laryngeal cartilage. To learn more about this novel prosthesis, see the slide show, read the article, and listen to the podcast describing the research and other published research in Volume 48, Issue 7.
