The goal of this study was to examine whether there were ethnic differences in polysomnographically recorded sleep, either in the controlled laboratory environment or in the home setting.
Prospective study of ethnic differences in stress physiology and sleep.
Two sleep recordings were performed on consecutive nights in a hospital-based sleep laboratory, followed 1 to 4 weeks later by a third sleep recording in the subject's home.
51 employed healthy adult subjects, aged 15 to 50 years. 24 self-identified as black, and 27 as white.
None.
Blacks had less slow wave sleep than did whites in both the sleep laboratory and in the home. Blacks had significantly more slow wave sleep at home compared to the hospital setting, while the reverse was true for whites. This location-by-ethnicity interaction could not be accounted for by depression ratings or social class.
The home setting is generally considered to be more ecologically valid than the controlled hospital-based laboratory setting for the monitoring of sleep. These data suggest that ethnicities may respond differentially to the sleeping environment. This observation may need to be taken into account in future epidemiologic studies of sleep.
本研究的目的是检验在多导睡眠监测记录的睡眠中，无论是在受控的实验室环境还是在家中环境下，是否存在种族差异。
关于压力生理学和睡眠中种族差异的前瞻性研究。
在一家医院的睡眠实验室连续两晚进行睡眠记录，1至4周后在受试者家中进行第三次睡眠记录。
51名在职健康成年受试者，年龄在15至50岁之间。24人自我认定为黑人，27人认定为白人。
无。
在睡眠实验室和家中，黑人的慢波睡眠都比白人少。与医院环境相比，黑人在家中的慢波睡眠明显更多，而白人则相反。这种地点与种族的相互作用不能用抑郁评分或社会阶层来解释。
一般认为，在家中环境下监测睡眠比在受控的医院实验室环境更符合生态学效度。这些数据表明，不同种族对睡眠环境的反应可能不同。在未来的睡眠流行病学研究中，可能需要考虑这一观察结果。
