A combined dietary and exercise intervention produces significant weight loss (mean 18.8 lb) in older obese adults with knee osteoarthritis, whereas exercise alone yields minimal weight loss (4.0 lb).
For older adults with knee osteoarthritis, combining a supervised exercise program (walking and strength training) with a structured dietary plan leads to significant weight loss. Exercise alone is unlikely to produce substantial weight loss in this population. The goal should be a moderate weight loss (e.g., 15 lbs) over 6 months through cognitive-behavioral dietary strategies and supervised physical activity.
The E&D group lost a mean of 18.8 lb (8.5 kg) at 6 months compared with 4.0 lb (1.8 kg) in the E group (P = .01).
Why this rating
Randomized clinical trial, but small sample size (n=24) and short duration (6 months).
