目的 研究失眠老年人客观测量的夜间睡眠与主观报告的早晨疼痛之间的关系；不仅要检查人与人之间睡眠和疼痛之间关联的差异（超过 14 天的平均水平），还要检查人体内的日常关联。设计横断面。设置佛罗里达州中北部。参与者 50 名患有失眠症的社区居住老年人（平均年龄 +/- 标准差 69.1 +/- 7.0，范围 60-90）。测量使用夜间活动记录仪进行每日家庭评估连续 14 天的睡眠测量和每日自我报告的疼痛。结果在人与人之间，14 天以上的平均睡眠与平均疼痛等级无关，但在失眠的老年人经历了高于平均总睡眠时间的一晚后，他或她随后报告了低于平均疼痛等级。该模型解释了大约 24% 的人内疼痛评分差异和 8% 的人际疼痛评分差异。 结论 对于患有失眠的老年人，睡眠和疼痛表现出日常关联（即随时间变化的协方差）。这种关联可能表明常见的生理系统是失眠和疼痛经历的基础。未来的研究应该检查睡眠治疗对疼痛和疼痛治疗对睡眠的交叉影响。
OBJECTIVESTo examine the relationship between objectively measured nocturnal sleep and subjective report of morning pain in older adults with insomnia; to examine not only the difference between persons in the association between sleep and pain (mean level over 14 days), but also the within-person, day-to-day association.DESIGNCross-sectional.SETTINGNorth-central Florida.PARTICIPANTSFifty community-dwelling older adults (mean age +/- standard deviation 69.1 +/- 7.0, range 60-90) with insomnia.MEASUREMENTSDaily home-based assessment using nightly actigraphic measurement of sleep and daily self-report of pain over 14 consecutive days.RESULTSBetween persons, average sleep over 14 days was not associated with average levels of rated pain, but after a night in which an older adult with insomnia experienced above-average total sleep time he or she subsequently reported below-average pain ratings. The model explained approximately 24% of the within-person and 8% of the between-person variance in pain ratings.CONCLUSIONSSleep and pain show day-to-day associations (i.e., covary over time) in older adults with insomnia. Such associations may suggest that common physiological systems underlie the experience of insomnia and pain. Future research should examine the crossover effects of sleep treatment on pain and of pain treatment on sleep.
