Examining interactions between exercise duration/frequency and maladaptive qualities in predicting eating pathology: a 20-year longitudinal cohort study

Prior research supports concurrent associations between exercise quantity, maladaptive qualities of exercise, and eating pathology. However, limited research has examined prospective associations, and no study has investigated how exercise quantity and quality jointly influence eating pathology over the long term. This study examined exercise quantity, qualities, and their interaction as prospective risk factors for eating pathology at 20-year follow-up. Men (N = 547) and women (N = 1,339) who endorsed exercise completed surveys at Time 1 [mean (SD) age = 29.42 (8.55)] and Time 2 [mean (SD) ag
