前逃亡奴是最初由非洲人和非洲人后裔 (Quilombolas) 在巴西偏远地区为逃避奴隶制而建立的定居点。由于个体历史的原因，基隆博斯现在表现出不同的工业化状态，使它们成为研究电气化对日常行为影响的理想选择。通过比较方法，我们旨在了解人类睡眠是否以及如何随着人造光的引入而改变。我们通过手腕活动测定法和慕尼黑 ChronoType 问卷（MCTQ；这两种仪器的结果高度相关）研究了逃亡奴的日常休息活动节律和睡眠模式。本研究比较了七个社区（MCTQ：N = 213/活动测定：N = 125）。不同城市化水平和电力使用历史的社区的光照、活动阶段、睡眠时间和持续时间有所不同。没有电的人和最近才用电的人平均比城市化社区的人睡得更早（中睡时间早约 1 小时）；睡眠时间往往会更长。我们和其他人的研究结果表明，电力的使用和现代生活方式已经改变了睡眠行为。为了了解这些变化对健康的影响，有必要进行进一步的研究。
Quilombos are settlements originally founded by Africans and African descendants (Quilombolas) in remote parts of Brazil to escape slavery. Due to individual histories, Quilombos nowadays exhibit different states of industrialisation, making them ideal for studying the influence of electrification on daily behaviour. In a comparative approach, we aimed to understand whether and how human sleep changes with the introduction of artificial light. We investigated daily rest-activity-rhythms and sleep-patterns in the Quilombolas’ by both wrist actimetry and the Munich ChronoType Questionnaire (MCTQ; the results of these two instruments correlated highly). Seven communities (MCTQ: N = 213/actimetry: N = 125) were compared in this study. Light exposure, phase of activity, sleep timing and duration differ across communities with various levels of urbanisation and histories of access to electricity. People living without electricity and those, who acquired it only very recently on average sleep earlier than those in more urbanised communities (mid-sleep about 1 hour earlier); sleep duration tends to be longer. Our results and those of others show that use of electricity and modern lifestyles have changed sleep behaviour. To understand the consequences of these changes for health, further studies are warranted.
