Sleep is essential for human beings, especially children. Insufficient sleep is linked to somatic and psychological problems. This study aims to describe nocturnal sleep patterns in children aged 7 to 13 years and investigate if sex or weekdays influence sleep habits. It also analyses factors associated with sleep length and the difference between sleep habits on weekends and weekdays.
A retrospective cross-sectional study with questionnaires from children with sleep complaints referred to our service (December 2003 to June 2009) in Sao Paulo City, Brazil. Median of sleep hours, time going to bed, waking up, and the difference in amount of sleep during weekends and weekdays were calculated. A generalized linear model was used to find associations between covariates and a) sleep hours, and b) sleep weekend minus - weekdays.
We analyzed 577 children (median 9.5 y, 61% boys). Median bedtime was 22h. Median wake up time was 7h on weekdays and 9h on weekends. Median sleep duration was 9.5h during weekdays and 10h on weekends. The median difference in the amount of sleep during weekends and weekdays was 0.5h (IQR=1.5). Shorter sleep duration was associated with age and school schedule. Higher difference weekend - weekdays was associated with older children, girls, and school schedule.
Children 7 to 13 years usually sleep more on weekends. Age, morning and full-time classes are associated with shorter sleep duration on weekdays and higher weekend-weekdays; girls sleep more during weekends.
睡眠对人类尤其是儿童至关重要。睡眠不足与身体和心理问题有关。本研究旨在描述7至13岁儿童的夜间睡眠模式，并调查性别或工作日是否会影响睡眠习惯。它还分析了与睡眠时间相关的因素以及周末和工作日睡眠习惯的差异。
对巴西圣保罗市转介到我们科室（2003年12月至2009年6月）的有睡眠问题的儿童进行问卷调查的回顾性横断面研究。计算睡眠时间的中位数、上床睡觉时间、醒来时间以及周末和工作日睡眠时间的差异。使用广义线性模型来寻找协变量与a）睡眠时间，以及b）周末睡眠减去工作日睡眠之间的关联。
我们分析了577名儿童（中位数9.5岁，61%为男孩）。就寝时间中位数为22点。工作日醒来时间中位数为7点，周末为9点。工作日睡眠时间中位数为9.5小时，周末为10小时。周末和工作日睡眠时间的中位数差异为0.5小时（四分位间距=1.5）。较短的睡眠时间与年龄和学校课程安排有关。周末与工作日睡眠时间差异较大与年龄较大的儿童、女孩和学校课程安排有关。
7至13岁的儿童通常在周末睡眠更多。年龄、上午课程和全日制课程与工作日较短的睡眠时间以及较大的周末与工作日睡眠时间差异有关；女孩在周末睡眠更多。
