Children with arthritis experience frequent pain, but the predictors of daily pain variations are largely unidentified. The goal of this study was to examine sleep quality as a predictor of pain in children with arthritis and to determine whether mood moderates this relationship.
In this prospective, longitudinal study children with polyarticular arthritis (n = 51, ages 8-16 years) tracked daily symptoms, including sleep quality over 2 months. Self-reported daily pain intensity, as indicated on a visual analog scale, was used as the primary outcome measure in multilevel models.
Poorer sleep quality was associated with higher next-day pain ratings (p < .01). Mood moderated this relationship such that as positive mood increased, the relationship between poor sleep quality and high pain weakened (p < .01). Daily pain did not predict nightly sleep quality (p > .05).
Sleep quality is an important predictor of pain in children with arthritis. These findings add to the growing body of literature on the use of daily diaries for analyzing patterns of pain, sleep, and mood in children with chronic painful conditions.
儿童关节炎患者常经历疼痛，但目前尚不清楚其日常疼痛变化的预测因素。本研究旨在探讨睡眠质量作为关节炎儿童疼痛的预测因素，并确定情绪是否调节这种关系。
在这项前瞻性、纵向研究中，51 名多关节型关节炎儿童（年龄 8-16 岁）在 2 个月内跟踪记录每日症状，包括睡眠质量。自我报告的每日疼痛强度，以视觉模拟量表表示，作为多层次模型中的主要结果测量指标。
较差的睡眠质量与次日更高的疼痛评分相关（p<.01）。情绪调节了这种关系，即随着积极情绪的增加，睡眠质量差与高疼痛之间的关系减弱（p<.01）。每日疼痛并不能预测夜间睡眠质量（p>.05）。
睡眠质量是关节炎儿童疼痛的重要预测因素。这些发现增加了关于使用日常日记分析慢性疼痛儿童疼痛、睡眠和情绪模式的文献数量。
