Abstract
STUDY OBJECTIVES: We undertook a study to describe and compare sleep deficiency and symptoms of pain, fatigue, and depressed mood in youth with childhood systemic lupus erythematosus (cSLE) to a healthy comparison group of youth and test the associations between sleep and symptoms of pain, fatigue, and depressed mood in youth with cSLE. METHODS: Forty-three youth (23 youth with cSLE; 20 age- and sex-matched healthy youth) wore actigraphs and completed sleep diaries for 10 days and completed self-report questionnaires on sleep quality, pain, fatigue, and depressed mood. RESULTS: On average, both groups had a total sleep time of less than 7 hours. Youth with cSLE had worse sleep efficiency (73.3%) and sleep regularity index scores (55.4) compared to the healthy comparison group of youth (79.2% and 60.1, respectively). Youth with cSLE had worse pain (P = .03) and fatigue (P = .004) compared to the healthy comparison group. Negative associations were found among self-reported sleep quality, sleep satisfaction, and symptoms of pain, fatigue, and depressed mood in youth with cSLE and wake after sleep onset was positively associated with fatigue. CONCLUSIONS: Poor sleep efficiency and sleep irregularity accompanied by symptoms of pain, fatigue, and depressed mood was prevalent in youth with cSLE. Youth with lupus should be encouraged to maintain a regular sleep schedule. Because this is the first study to incorporate objective sleep and sleep regularity measures in youth with cSLE, additional studies with objective and self-reported sleep measures are needed to replicate our findings.
