Self-rated health measure can predict outcomes in knee OAFebruary 15, 2013 in Medicine & Health / Arthritis & Rheumatism
(HealthDay)—For patients with symptomatic knee osteoarthritis (OA), a single-item measure of self-rated health can be used to predict mental and social health outcomes, according to a study published in the February issue of Arthritis Care & Research.
Daniel L. Riddle, P.T., Ph.D., and Levent Dumenci, Ph.D., of the Virginia Commonwealth University in Richmond, evaluated (in a multicenter observational study) the influence of self-rated health, as assessed with a simple, single-item measure, on physical, mental, and social health in a cohort of 1,127 individuals with symptomatic knee OA from the Osteoarthritis Initiative study. Participants were followed for a three-year period.
The researchers found that previous self-rated health predicted current mental and social health, while prior social health was predictive of current self-rated health. Furthermore, changes in mental and social health were mediated by self-rated health. Self-rated health mediated changes only in social health over all time periods studied.
"In conclusion, our study demonstrates the potential utility of self-rated health assessments for persons with symptomatic knee OA in clinical settings," the authors write. "Our study suggests that a simple-to-use single-item self-rated health measure is predictive of future health status and mediates changes in both mental and social health."
The Osteoarthritis Initiative Study was sponsored by various pharmaceutical companies.
