该研究的目的是检查种族对睡眠调节的影响。来自四个种族的73名正常志愿者（17名非洲裔美国人，10名亚洲人，30名高加索人和16名西班牙裔人）在实验室连续两晚进行睡眠多导睡眠图记录。受试者身体和心理健康状况良好，无睡眠/觉醒主诉或睡眠障碍症状。除了微小的差异外，四组之间的睡眠连续性、睡眠结构和快速眼动（REM）睡眠模式是相当的。非裔美国人有更多的第1和第2阶段睡眠和减少第4阶段睡眠的证据，而西班牙裔有更高的REM密度。这些初步发现表明，不同文化的睡眠模式非常相似。然而，在不同种族之间存在着重要的差异，特别是在睡眠深度和阶段性REM测量方面。由于睡眠障碍是情绪障碍的常见症状，并且由于许多精神活性药物影响睡眠，因此睡眠模式的跨种族差异可能对精神障碍的治疗和预防具有潜在意义。(C)1999 Elsevier Science Ltd.保留所有权利。
The purpose of the study was to examine ethnic influences on sleep regulation. Seventy-three normal volunteers from four ethnic groups (17 African-Americans, 10 Asians, 30 Caucasians and 16 Hispanics) were studied for two consecutive nights with sleep polysomnography recordings in the laboratory. The subjects were in good physical and psychological health, and were asymptomatic with respect to sleep/wake complaints or sleep disorders. With the exception of minor differences, sleep continuity, sleep architecture and rapid eye movement (REM) sleep patterns were comparable among the four groups. African-Americans had evidence of more stages 1 and 2 and diminished stage 4 sleep, whereas the Hispanics had higher REM density. These preliminary findings suggest that sleep patterns are remarkably similar across cultures. There are, however, important cross-ethnic differences, specifically in the depth of sleep and in phasic REM measures. Because sleep disturbances are common symptoms of emotional disorders and since many psychoactive agents affect sleep, cross-ethnic differences in sleep patterns may have potential implications for the treatment and prevention of psychiatric disorders.
