Individuals often had multiple conditions. Fatigue was related to overall quality of life and to the quality-of-life domains of physical health and environment; anxiety was related to the psychological domain.ConclusionsFatigue, pain, anxiety, and depression, potentially treatable symptoms, occur frequently in adults with DMD and significantly influence health-related quality of life.
