OBJECTIVE
This study compared sleep quality and stress-related symptoms between older beds (>/=5 years) and new bedding systems.
METHODS
A convenience sample of healthy subjects (women = 30; men = 29) with minor musculoskeletal sleep-related pain and compromised sleep, but with no clinical history of disturbed sleep, participated in the study. Subjects recorded back discomfort and sleep quality upon waking for 28 consecutive days in their own beds (baseline) and for 28 consecutive days (post) on a new bedding system using visual analog scales. Following baseline measures, participant's beds were replaced by new, medium-firm beds, and they again rated their sleep quality and back discomfort. Stress was assessed by a modified stress questionnaire.
RESULTS
Repeated-measures analysis of variance was used to treat sleep quality and efficiency and factored responses of the stress items. Results indicated that the subjects' personal bedding systems average 9.5 years old and were moderately priced. Significant (P < .01) improvements were found between pre- and posttest mean values in sleep quality and efficiency. Continued improvement was noted for each of the 4-week data gathering period. Stress measures yielded similar positive changes between pre- and posttest mean values.
CONCLUSION
Based on these data, it was concluded that, in this population, new bedding systems increased sleep quality and reduced back discomfort, factors that may be related to abatement of stress-related symptoms.
目的
本研究比较了使用年限较长（≥5年）的旧床与新型床上用品系统的睡眠质量及与压力相关的症状。
方法
选取了便利样本，包括30名女性和29名男性健康受试者，他们有轻微的与肌肉骨骼相关的睡眠疼痛且睡眠质量受损，但无睡眠障碍的临床病史，参与了本研究。受试者使用视觉模拟量表，在自己的床上连续记录28天醒来后的背部不适和睡眠质量（基线），并在新型床上用品系统上连续记录28天（后期）。在基线测量后，将参与者的床更换为新的中等硬度的床，他们再次对睡眠质量和背部不适进行评分。通过改良的压力问卷评估压力。
结果
采用重复测量方差分析来处理睡眠质量和效率以及压力项目的分项反应。结果表明，受试者个人床上用品系统的平均使用年限为9.5年，价格适中。在睡眠质量和效率的测试前和测试后平均值之间发现了显著（P < .01）改善。在每个为期4周的数据收集期都注意到持续改善。压力测量在测试前和测试后平均值之间也产生了类似的积极变化。
结论
基于这些数据，得出结论：在该人群中，新型床上用品系统提高了睡眠质量，减轻了背部不适，这些因素可能与缓解与压力相关的症状有关。
