睡眠是健康发育的重要标志，与情绪、行为和认知发展有关。关于儿童睡眠的纵向数据有限，只有少数来自低收入和中等收入国家（LMIC）的报告。我们在巴西佩尔松进行的一项以人群为基础的纵向研究中调查了睡眠参数和相关的社会人口学特征。使用了Pelanmar 2004年出生队列的数据（N = 3842）。婴儿睡眠通过母亲在3个月、12个月、24个月和48个月的报告收集：睡眠持续时间、睡觉和醒来时间、夜间觉醒、共睡和睡眠障碍（24个月和48个月）。与高收入国家（HIC）的儿童相比，巴西儿童的睡眠和起床时间发生了实质性变化，大约延迟了2小时。这些在生命的前4年保持稳定。这一人群还显示出高水平的共睡，始终保持稳定（49.0-52.2%）。晚睡时间与母亲受教育程度和家庭收入较高有关。在收入和母亲受教育程度较低的家庭以及母乳喂养的儿童中，同床共枕的比例较高。所有其他睡眠参数与以前报告的HIC数据大致相似。在巴西这个代表性的社区儿童样本中，生物节律的转变挑战了我们对最佳睡眠习惯和建议的理解。生物节律随着就寝时间的推迟而改变，大约为2小时（22.18小时）。晚睡时间与母亲教育程度和家庭收入有关。高水平的共同睡眠普遍存在，直到4岁（49%在3个月到52%在4岁）。在收入和母亲受教育程度较低的家庭中，同床共枕更为普遍。
Sleep is an important marker of healthy development and has been associated with emotional, behavioral, and cognitive development. There is limited longitudinal data on children's sleep with only a few reports from low- and middle-income countries (LMICs). We investigate sleep parameters and associated sociodemographic characteristics in a population-based longitudinal study in Pelotas, Brazil. Data from the Pelotas 2004 Birth Cohort were used (N = 3842). Infant sleep was collected through maternal report at 3, 12, 24, and 48 months: sleep duration, bed and wake time, nighttime awakenings, co-sleeping and sleep disturbances (24 and 48 months). Compared to children in high-income countries (HICs), children in Brazil showed a substantial shift in rhythms with later bed and wake times by approximately 2 hours. These remain stable throughout the first 4 years of life. This population also shows high levels of co-sleeping which remain stable throughout (49.0–52.2%). Later bedtime was associated with higher maternal education and family income. Higher rates of co-sleeping were seen in families with lower income and maternal education and for children who were breastfed. All other sleep parameters were broadly similar to data previously reported from HICs. The shift in biological rhythms in this representative community sample of children in Brazil challenges our understanding of optimal sleep routine and recommendations. Biological rhythms are shifted with later bedtime by approximately 2 h (22.18 hours). Later bedtime is associated with higher maternal education and family income. High levels of co-sleeping are prevalent until 4 years of age (49% at 3 months to 52% at 4 years). Co-sleeping was more prevalent in families with lower income and maternal education.
