Sleep latency and lifestyle in Oxfordshire villages.
Sleep latency, the usual delay in falling asleep, was estimated in 689 male and 757 female residents of a group of Oxfordshire villages by means of a sleep questionnaire. Sleep latency is analysed in relation to 59 descriptive elements of lifestyle and reported feelings. The pattern of association is broadly similar in the two sexes, and multivariate analysis identifies boredom and insufficient to do, mild morbidity, and use of sleeping tablets and tranquillizers as important correlates of long sleep latency in both sexes. These data are compared with a similar analysis of the correlates of sleep duration and sleep quality. It is concluded that sleep latency represents an important measure of well-being.
