Purpose: To examine the association between obesity and functioning of patients with osteoarthritis of the hip or knee. Relevance: Osteoarthritis (OA) is a common joint disorder, which has a major impact on functioning in daily life. OA accounts for more disability among the elderly than any other disease. On average, patients with OA are heavier than those without OA, and overweight is considered to be one of the main risk factors for the incidence and progression of OA. On basis of the present information on the role of obesity in the onset and progression of OA and the beneficial effects of weight reduction on physical disability, it can be expected that obese patients with OA have more physical disabilities compared to non-obese patients with OA. However, at this moment it is not known in which specific aspects of physical disability obese patients differ from non-obese patients. Also, no information is available whether obese patients with OA cope differently with their complaints compared to non-obese patients. Information on this can contribute to the treatment of obese patients with OA of hip and/or knee. Participants: This study involved 180 patients with hip or knee osteoarthritis according to the clinical criteria of the American College of Rheumatology. Methods: A cross-sectional study was conducted, using baseline data from a randomized controlled trial comparing two types of physiotherapeutic interventions in primary care. Analysis: To determine the association of obesity (BMI > 30) and functioning, linear regression analyses were performed on the outcome measures pain (VAS), fatigue (VAS), physical function (WOMAC, walking time test), physical activity, range of motion and muscle strength. Also, the psychosocial variables coping with pain and locus of control were compared. Analyses were performed without and with correction
for pain.Results: In patients with knee OA, obesity has a significant negative association with pain, fatigue, physical function, level of physical activity, range of motion and muscle strength. After correction for pain the negative association remained significant between obesity and the outcome measures timed walking test, physical activity, range of motion and muscle strength. Furthermore, obese patients with knee OA have a higher level of powerful others locus of control. In patients with hip OA, the association between obesity and functioning was less clear. A significant negative association was found, both with and without correction for pain, between obesity and the outcome measures physical function, muscle strength of knee extension and range of motion of the knee. Further, obese patients had a lower level of the pain coping strategy ‘worrying’. Conclusions: In patients with osteoarthritis, obesity is an important factor, which negatively influences the overall functioning in daily life. Especially in patients with knee OA the influence of obesity is substantial. Furthermore, patients with obesity have a different coping styles compared to patients without obesity. Implications: In clinical practice these results can be used to show patients the influence of obesity on their functioning. Also, when decisions are made about the content of treatment of patients of OA their body weight needs to be taken into account. (aut. ref.)
