睡眠受到几个因素的调节，包括性别、年龄和生理时钟类型。据推测，当代城市人口面临着睡眠时间缩短和睡眠质量下降的压力。Baependi是巴西的一个小镇，为研究具有保守生活方式的高度混合的农村人口的睡眠模式的影响提供了机会。我们分别使用匹兹堡睡眠质量指数、埃普沃思嗜睡量表和晨间-夜间问卷调查表评估睡眠特征、白天过度嗜睡和时间类型。样本包括来自Baependi心脏研究的1，334例受试者（41.5%为男性;年龄：46.5 ± 16.2岁，范围：18-89岁）。自我报告的平均睡眠时间为07：07 ± 01：31（就寝时间为22：32 ± 01：27，醒来时间为06：17 ± 01：25 hh：min），睡眠质量评分为4.9 ± 3.2，时间类型为63.6 ± 10.8，白天嗜睡为7.4 ± 4.8。尽管人口中的晨起倾向有所转变，但时钟类型仍然与报告的实际睡眠时间相关。年龄和性别影响睡眠和时型的个体发育，年龄越大，睡眠时间越早，睡眠持续时间越短。女性睡眠时间更长，睡眠质量比男性差（p < 0.0001）。这项研究提供了间接证据，支持睡眠时间早于完全城市化的假设。
Sleep is modulated by several factors, including sex, age, and chronotype. It has been hypothesised that contemporary urban populations are under pressure towards shorter sleep duration and poorer sleep quality. Baependi is a small town in Brazil that provides a window of opportunity to study the influence of sleep patterns in a highly admixed rural population with a conservative lifestyle. We evaluated sleep characteristics, excessive daytime sleepiness, and chronotype using the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Morningness-Eveningness Questionnaire questionnaires, respectively. The sample consisted of 1,334 subjects from the Baependi Heart study (41.5% male; age: 46.5 ± 16.2 y, range: 18–89 years). Average self-reported sleep duration was 07:07 ± 01:31 (bedtime 22:32 ± 01:27, wake up time: 06:17 ± 01:25 hh:min), sleep quality score was 4.9 + 3.2, chronotype was 63.6 ± 10.8 and daytime sleepiness was 7.4 ± 4.8. Despite a shift towards morningness in the population, chronotype remained associated with reported actual sleep timing. Age and sex modulated the ontogeny of sleep and chronotype, increasing age was associated with earlier sleep time and shorter sleep duration. Women slept longer and later, and reported poorer sleep quality than men (p < 0.0001). This study provides indirect evidence in support of the hypothesis that sleep timing was earlier prior to full urbanisation.
