Fatigue in young people with Duchenne muscular dystrophy

Aim To describe fatigue in Duchenne muscular dystrophy (DMD) from patients’ and parents’ perspectives and to explore risk factors for fatigue in children and adolescents with DMD. Method A multicentre, cross‐sectional study design was used. Seventy‐one patients (all males; median age 12y, age range 5–17y) identified via the Canadian Neuromuscular Disease Registry, and their parents completed questionnaires. Subjective fatigue was assessed using the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale by child self‐report and parent proxy‐report. Results Patients with DMD across ages and disease stages experienced greater fatigue compared to typically developing controls from published data. Sleep disturbance symptoms were associated with greater fatigue by child self‐report (ρ=–0.42; p=0.003) and parent proxy‐report (ρ=–0.51; p
