| Annotation | Few reports have examined in detail the relationship between circadian rhythms, sleep patterns and ageing, as in this study of middle-aged and older subjects (ages 40 to 84). A subset of those aged 65 and over had reported sleep disturbance for at least 1 year before. Polysomnography was obtained, and body core temperature recorded continuously for 24 hours at the Laboratory of Human Chronobiology, Cornell University Medical College. There were no differences in sleep quality between middle-aged and non-sleep disturbed older people. However, timing of the minimum body temperature was earlier in the older non-sleep disturbed than in the middle-aged. Sleep disturbed older people had shorter total sleep times, reduced sleep efficiency, more waking time after sleep onset, and a reduced proportion of REM sleep compared with non-sleep-disturbed older people. There were no differences in rhythm of body temperature between the two older groups. For the entire group, age was correlated negatively with total sleep time, sleep efficiency, and timing of temperature minimum. That age-related changes in sleep may be associated with ageing of the circadian system was supported only to a limited degree: there may be other causes. (RH). |
