Youth with sickle cell disease (SCD) experience disease effects including vaso-occlusive pain crises, poor sleep quality, and fatigue. The present study examines how sleep quality and pain medications impact fatigue in youth with SCD. Daily diaries assessing pain, fatigue, sleep quality, mood, and use of pain medications from 25 youth with SCD ages 11 to 18 years were collected for eight consecutive weeks. Poor sleep quality predicted increases in next-day fatigue levels while controlling for pain and mood. Sleep quality did not moderate the existing temporal relationship between pain and next-day fatigue established by Reinman et al. (2019) as predicted. Non-opioid medications affected ratings of next-day fatigue but opioid medications did not. Sleep quality appears to play an important role in predicting next-day fatigue levels and may be an important target for intervention. Pain medication use did not substantially contribute to prospective fatigue levels among youth, but requires further study.
