许多基于人群的调查报告称，睡眠质量不佳的患病率随着年龄的增长而增加。尽管研究结果具有一致性，但目前尚不清楚与年龄相关的整体身体健康状况下降在多大程度上与这些结果相关。解决这个问题的一种方法是对这些混杂变量进行多变量调整。之前使用这种方法的一些研究并未显示睡眠质量不佳的患病率与年龄相关的预期增加。另一种方法是对经过仔细筛选的健康人群的睡眠进行研究。目前的研究报告了 50-65 岁人群睡眠障碍的患病率，作为正在进行的运动和心血管功能研究的一部分，他们对身体健康状况进行了仔细筛查。自我报告的每晚或几乎每晚入睡困难（1.1% M，2.6% F）、醒来和重新入睡困难（4.4% M，3.3% F）以及每周至少使用两次催眠药物（1.6% M，2.6% F）的患病率始终低于几乎所有先前针对同龄个体的基于人群的研究。这意味着，当考虑到整体身体健康因素时，睡眠质量下降本身并不一定是衰老的不可避免的组成部分。正如其他研究表明的那样。自我报告的抑郁症与睡眠质量差之间存在微小但具有统计学意义的关系。尽管睡眠质量不佳的患病率较低，但约有三分之一的人表示感觉休息不好和/或没有获得所需的睡眠。这项研究中的个体还报告说，与 30 年前的标准数据相比，他们的睡眠时间明显减少。总的来说，这些数据提出了个人主动减少他们想要或需要的睡眠量的长期趋势的可能性。
Many population-based surveys have reported that the prevalence of poor sleep increases with age. Despite the uniformity of findings, it remains unclear to what extent age-related declines in overall physical health are related to those results. One approach to this problem has been to adjust for such confounding variables multivariately. Some prior studies using this approach have not shown the expected age-related increases in the prevalence of poor sleep. Another approach has been the study of sleep in carefully screened, healthy populations. The current study reports the prevalence of disturbed sleep in a population, ages 50-65, carefully screened for physical health as part of an ongoing study of exercise and cardiovascular function. The prevalance of self-reported trouble falling asleep every night or almost every night (1.1% M, 2.6% F), trouble awakening and returning back to sleep (4.4% M, 3.3% F), and use of hypnotic medication at least twice a week (1.6% M, 2.6% F) were consistently lower than in nearly all previous population-based studies of individuals of comparable age. This implies that when overall physical health factors are taken into account a decline in sleep quality is not necessarily an inevitable component of aging per se. As has been shown in other studies. there were small but statistically significant relationships between self-reported depression and poor sleep. Despite the low prevalance of poor sleep, about a third of the population reported feeling not well-rested and/or not getting the sleep they required. The individuals in this study also reported obtaining significantly less sleep relative to normative data from 30 years ago. Taken as a whole, these data raise the possibility of secular trends for individuals to actively curtail the amount of sleep they desire or need.
