The Arthritis, Diet, and Activity Promotion Trial

The goal of the dietary weight-loss intervention was to produce and maintain a mean weight-loss of 5% initial body weight during the 18-month intervention, using dietary counseling and behavior modification.

Participants participated in resistance training (15 minutes) and aerobic exercise (30 minutes) 3d/week for 18-months. The first 4-months of the exercise training were facility-based. After 4-months, participants were allowed to transition to a home-based intervention if they chose to.
