研究目的：通过对有失眠和无失眠的中年女性进行为期一周的实地睡眠研究，描述自我报告的午睡行为以及午睡历史、研究期间的午睡行为、主观和客观失眠指标以及自我报告的日间嗜睡之间的关系。设计：描述性/比较性二次分析。设置：参与者的个人家庭。参与者：自我报告失眠的中年女性（平均年龄46±4岁）（n=101）和睡眠充足的女性（n=30）。干预措施：N/测量方法和结果：通过多导睡眠图（PSG）、每日日记和睡眠史表评估睡眠模式。尽管所有女性都被要求不要午睡，但47%的女性在研究期间报告了午睡行为。日间小睡史与午睡行为之间存在密切关系(chi (2)=25.63， p小于或等于。001)，以及白天感到困倦或难以保持清醒的历史（即嗜睡）和午睡行为(chi (2)=18.05， p小于或等于。001)。也有中度显著相关（p小于或等于05）(r=。25)疲劳和午睡时间之间的关系。午睡组和不午睡组在睡眠变量上没有统计学差异。在午睡组中，睡眠效率< 85%（客观失眠症）的女性与睡眠效率< 85%（客观失眠症）的女性之间没有差异。结论：习惯性午睡行为可能是女性失眠患者日间嗜睡的指示，但它不一定与失眠的主观或客观测量有关。长期研究表明，经常午睡的女性可能无法在白天避免午睡。
Study Objectives: To describe self-reported nap behavior and relationships among nap history, nap behavior during the study, indicators of subjective and objective insomnia, and self-reported daytime sleepiness from data previously obtained in a week-long field study of sleep in midlife women with and without insomnia.Design: Descriptive/comparative secondary analysis.Setting: Individual homes of the participants.Participants: Midlife women (mean age 46 +/-4 years) with self-reported insomnia (n=101) and women with adequate sleep (n=30).Interventions: N/AMeasurements and Results: Sleep patterns were assessed by polysomnography (PSG), daily diaries, and a sleep history form. Although all women were requested not to nap, 47% of the women reported nap behavior during the study. Strong relationships were observed between a history of daytime naps and nap behavior (chi (2)=25.63, p less than or equal to .001), and a history of feeling sleepy or struggling to stay awake during the daytime (i.e., sleepiness) and nap behavior (chi (2)=18.05, p less than or equal to .001) during the study. There was also a modest significant (p less than or equal to 05) correlation (r=. 25) between tiredness and nap duration during the study. There were no statistical differences in sleep variables between the napping and non-napping groups. In the napping group, there were no differences between women with sleep efficiency < 85% (objective insomnia) and those with sleep efficiency > 85%.Conclusions: Habitual nap behavior may be indicative of daytime sleepiness in women with insomnia, but it is not necessarily related to subjective or objective measures of insomnia. Women who routinely nap may be unable to refrain from napping during the daytime in long-term research studies.
