Fatigue is commonly reported as prodromal to acute and chronic illness. At this point, we do not understand the etiology of fatigue; it is often confused with sleepiness. Longitudinal assessments of self-reported symptoms (fatigue, sleep, pain, depression), comorbid conditions, physical activity, and biomarkers will be collected monthly over 1 year to allow us to assess potential temporal effects of fatigue on daytime and nighttime (sleep) activity patterns in adults and children.
