Older adults complain of sleep disturbances more often than younger adults do. It is not clear whether the age-related rise in sleep problems is related to aging itself or to health-related quality of life. The aim of this study was to explore the presence of self-reported sleep problems in healthy elderly individuals and to evaluate whether changes occurred over a 3-year follow-up.
A total of 314 older community-dwelling volunteers, aged 71.6±1.0 years old, were examined and followed for 3 years. All of the subjects completed questionnaires evaluating anxiety, depression, and sleepiness and the Pittsburgh Sleep Quality Index (PSQI) at the first and second evaluations. On the basis of the PSQI items, the subjects were classified as good or bad sleepers and as short, normal, or long sleepers.
At baseline, 53% of the subjects reported good sleep, with 61% reporting a sleep duration of approximately 7 hr. The total sleep time and the numbers of short, normal, and long sleepers were similar at baseline and at 3 years later. Over time, there was a slight increase (p<0.001) in bad sleepers (53%) and a rise in the occasional hypnotic intake (p<0.001). Considering individual variation, the majority of subjects remained stable at follow-up for sleep duration (65%), sleep quality (75%), and medication (83%).
In a healthy older population, the majority of the subjects did not report bad and short sleep at baseline and did not have significant changes in self-perceived sleep 3 years later. These findings suggest that the reported sleep disturbances described in the elderly are more dependent on physical, environmental, and health factors rather than on age-dependent sleep changes.

老年人比年轻人更常抱怨睡眠障碍。目前尚不清楚与年龄相关的睡眠问题增加是与衰老本身有关，还是与健康相关的生活质量有关。本研究旨在探讨健康老年人中是否存在自我报告的睡眠问题，并评估其在 3 年随访期间是否发生变化。
共纳入 314 名年龄在 71.6±1.0 岁的社区居住的老年人志愿者进行检查，并随访 3 年。所有受试者在第一次和第二次评估时均完成了评估焦虑、抑郁和嗜睡的问卷以及匹兹堡睡眠质量指数（PSQI）。根据 PSQI 项目，受试者被分类为睡眠良好或睡眠不佳，以及短、正常或长睡眠时间。
在基线时，53%的受试者报告睡眠良好，61%的受试者报告睡眠时间约为 7 小时。总睡眠时间以及短、正常和长睡眠时间在基线和 3 年后相似。随着时间的推移，睡眠不佳（53%）的人数略有增加（p<0.001），偶尔使用催眠药物（p<0.001）的人数也有所增加。考虑到个体差异，大多数受试者在随访期间睡眠持续时间（65%）、睡眠质量（75%）和药物使用（83%）仍保持稳定。
在健康的老年人群中，大多数受试者在基线时并未报告睡眠不佳和睡眠短，3 年后自我感知的睡眠也没有明显变化。这些发现表明，老年人中描述的睡眠障碍更多地取决于身体、环境和健康因素，而不是年龄相关的睡眠变化。
