The Osteoarthritis Prevention Study
Wake Forest University
Summary
The goal of this study is to establish the efficacy of an intervention of dietary weight loss, exercise, and weight-loss maintenance for knee Osteoarthritis (OA) prevention in adult females aged ≥ 50 years with obesity and no or infrequent knee pain. The primary aim is to compare the effects of a dietary weight loss, exercise, and weight-loss maintenance to an attention control group in preventing the development of structural Magnetic Resonance Imaging (MRI) knee OA. Secondary aims will determine the intervention effects on pain, mobility, health-related quality of life, knee joint compressive forces, inflammatory measures, weight loss, exercise self-efficacy, and cost-effectiveness of this intervention.
Description
Osteoarthritis (OA), the leading cause of disability among adults, is without a cure and is associated with significant comorbidities. OA ranks as the third most common diagnosis for hospital inpatient stays with 1.25 M per year, with the knee the most commonly affected weight-bearing joint. This study will address knee OA disease prevention in adult females because prevention of OA is preferable to treatment, females are affected at nearly twice the rate as males, and to date interventions designed to slow or stop knee OA progression have failed. Dietary weight loss, with and without exercise…
