Obesity, ostearthritis and clinical treatment

ABSTRACT

OBJECTIVE: To evaluate the relationship between BMI and pain and function in patients with OA undergoing medical treatment following OARSI recommendations. METHODS: Thirty-eight patients were classified according to their arthritis degree by X-ray and body mass index (BMI). All patients completed the WOMAC, Lequesne, and visual analogue pain scale (VAS) questionnaires at baseline and after six months treatment. All patients were treated with diacerhein and analgesics (according to pain), orthotics (when indicated), and an educational program on osteoarthritis. They were instructed on balanced diet and exercise at least three times a week. RESULTS: There was no significant BMI variation in this study. The higher the initial BMI, the lower the improvement in pain (p = 0.03). Pain did not improve significantly (p = 0.2). Function improved (p <0.001) in inverse ratio to the initial BMI. CONCLUSION: BMI determines how patients will improve pain and function. .
