To 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.
Cross-sectional.
North-central Florida.
Fifty community-dwelling older adults (mean age+/-standard deviation 69.1+/-7.0, range 60-90) with insomnia.
Daily home-based assessment using nightly actigraphic measurement of sleep and daily self-report of pain over 14 consecutive days.
Between 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.
Sleep 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.
研究老年人失眠患者中客观测量的夜间睡眠与早晨主观疼痛报告之间的关系；不仅要研究睡眠与疼痛之间关联的人群差异（14 天内的平均值），还要研究个体内的日常关联。
横断面研究。
佛罗里达州中北部。
50 名患有失眠症的社区居住的老年人（平均年龄+/-标准差 69.1+/-7.0，范围 60-90）。
使用夜间活动记录仪对睡眠进行为期 14 天的每日家庭评估和每日自我报告疼痛。
在个体之间，14 天内的平均睡眠时间与平均疼痛评分无关，但在失眠的老年人经历了高于平均总睡眠时间的一夜之后，他或她随后报告的疼痛评分较低。该模型解释了疼痛评分个体内和个体间方差的约 24%和 8%。
失眠症老年人的睡眠和疼痛存在日常关联（即随时间变化而共变）。这种关联可能表明共同的生理系统是失眠和疼痛的基础。未来的研究应研究睡眠治疗对疼痛和疼痛治疗对睡眠的交叉影响。
