这项研究验证了一个假设，即71 - 91岁的健康老年人的睡眠受损可能是由于生活方式不规律引起的昼夜节律功能障碍。25名老年女性、20名老年男性和21名年轻对照（19 - 28岁）进行了以下研究：1）在实验室中测量的客观睡眠，2）通过匹兹堡睡眠质量指数（PSQI）测量的主观睡眠质量，3）社会节奏度量（SRM），一种量化日常生活节奏的工具。与预测相反，SRM量表显示，老年组完成的活动数量和他人参与的数量与年轻人一样多。此外，他们的日常生活方式比年轻人更有规律，尽管他们的主观和客观睡眠确实受到了损害。这表明，这些老年人的生活方式一直很规律，这对他们的健康和活力起到了保护作用，或者他们的规律性是对昼夜节律系统中与年龄相关的变化的适应性反应。
This study tested the hypothesis that the impaired sleep of healthy 71-91 year olds might be due to circadian dysfunction stemming from irregularity of life-style. Twenty-five old women, 20 old men and 21 young controls (19-28 years old) were studied in relation to 1) objective sleep as measured in the laboratory, 2) subjective sleep quality as measured by the Pittsburgh sleep quality index (PSQI) and 3) the social rhythm metric (SRM), an instrument to quantify the daily rhythms of life. Contrary to prediction, the SRM scales revealed that the older group had just as many activities completed and just as much other-person involvement as the young. Moreover, they showed a significantly greater regularity in daily life-style than the young, despite showing reliably impaired subjective and objective sleep. This suggests either that these seniors have always been regular in their life-style and that this has been protective of their health and vigor, or that their regularity has been developed as an adaptive response to age-related changes in the circadian system.
