Temporal Daily Relationships Between Sleep and Pain in Adolescents With Systemic Lupus Erythematosus

Abstract

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder characterized by recurrent episodes of pain. This study aimed to describe the temporal daily relationships between sleep and pain in adolescents with SLE. Twenty-three adolescents with SLE recruited from a pediatric hospital wore actigraphy and completed diaries. Generalized estimating equation models were used. On average, evening pain negatively predicted subsequent sleep quality that night, and, on average, sleep quality negatively predicted morning pain. Shorter total sleep time significantly predicted higher morning pain (95% confidence intervals [CI], -0.38 to -0.03, p = .02), whereas sleep efficiency and sleep quality were not significantly associated with morning pain (95% CI, -0.03 to 0.03; 95% CI, -0.08 to 0.06, respectively). Subsequent evening pain did not predict daily nighttime sleep DISCUSSION: Our findings suggest that sleep is a target for pain interventions to include among adolescents with SLE.
