Study finds, Changes in body weight and knee pain in adults
A Study was conducted to determine whether long-term diet (D) and exercise (E) interventions, alone or in combination (D+E), have beneficial effects for older adults with knee osteoarthritis 3.5-years after the interventions end.

184 participants were included in the trial. Participants were older, overweight and obese adults with radiographic and symptomatic knee osteoarthritis in at least one knee who completed 1.5-year D+E (N=27), D (N=35), or E (N=32) interventions and returned for 5-year follow-up testing an average of 3.5-years later.

--During the 3.5-years following the interventions, weight regain in D+E and D was 5.9 kg and 3.1 kg, respectively, with a 1 kg weight loss in E.

--Compared to baseline, weight (D+E, -3.7 kg; D, -5.8 kg, E, -2.9 kg) and WOMAC pain (D+E, -1.2; D, -1.5; E -1.6) were lower in each group at 5-year follow-up.

--The effect of group assignment at 5-year follow-up was significant for body weight, with D less than E.

Older people with knee osteoarthritis who underwent a 1.5-year diet or diet plus exercise intervention experienced partial weight regain 3.5 years later, but they maintained statistically significant changes in weight loss and knee pain reductions relative to baseline.
