Emergent work suggests that sleep is a robust biobehavioral predictor of pain; however, it remains unclear how sleep is prospectively linked to pain on a day-to-day basis among older adults. The current prospective study examined how sleep duration (total sleep time), quality (sleep efficiency, wake after sleep onset), and late and irregular sleep timing influenced next-day pain perception among community-dwelling older adults ( = 10; 65 matched observations) with lower extremity chronic pain over 1 week. Multilevel modeling estimated the association between sleep (Actigraph GT9X Link) and pain perception (Brief Pain Inventory Short Form). Increased wake after sleep onset (B = 0.19, = 0.04), sleep variability (B = 0.02, = 0.01), and later midsleep time (B = 0.40, < 0.05) were associated with increased pain interference the following day. Findings support the idea that timely sleep interventions may reduce the effect of poor sleep on next-day pain in older adults. [(4), 173-179.].
新出现的研究表明，睡眠是疼痛的一种强大的生物行为预测指标；然而，对于老年人来说，睡眠如何在每天的基础上与疼痛产生前瞻性联系仍不清楚。本前瞻性研究考察了睡眠持续时间（总睡眠时间）、质量（睡眠效率、睡眠起始后醒来）以及晚和不规则的睡眠时间如何影响下肢慢性疼痛的社区居住老年人（n = 10；65 个匹配观察）在一周内第二天的疼痛感知。多层次模型估计了睡眠（Actigraph GT9X Link）和疼痛感知（简短疼痛量表）之间的关联。睡眠起始后醒来增加（B = 0.19，p = 0.04）、睡眠变异性增加（B = 0.02，p = 0.01）和晚睡时间（B = 0.40，p < 0.05）与第二天疼痛干扰增加相关。研究结果支持这样一种观点，即及时的睡眠干预可能会减轻老年人睡眠不佳对第二天疼痛的影响。
