The aim of the study was to compare sleep-wake schedules between snoring and nonsnoring preschool age children.
Daytime and nighttime sleep duration, daytime and nighttime symptoms were assessed in 34 children at preschool age who snore (5.38+/-1.21 years) and in 66 age- and sex-matched nonsnorers (5.67+/-1.12 years). The snoring group consisted of children with obstructive sleep apnea (OSA) scores <+3.5 and >-1, the nonsnoring group with OSA score <-1.
Children who snore differ from the nonsnorers in daytime sleep duration (51.62+/-28.9 minutes vs. 10.70+/-20.2 minutes; p<0.001), but not in nighttime sleep (10.97+/-0.52 hours vs. 9.83+/-1.34 hours; p>0.05). The percentage of children with daytime napping was higher in the snoring group than in the nonsnorers (47.1% vs. 9.1%; p<0.00004), and parents-reported behavioral problems were more frequent in children who snore (41.2% vs. 19.7%; p<0.02). Multivariate odds ratios, including variables for nighttime (sleep apnea) and daytime symptoms (daytime napping and oral breathing), showed that regular sleep during the day was the most predictive of snoring (OR=6.1; 95%CI 1.76-21.04; p<0.005).
In preschool age children, when the daytime nap begins to disappear, snoring may have an effect on daytime schedule through an increased need for daytime sleep.
本研究旨在比较打鼾和不打鼾学龄前儿童的睡眠-觉醒时间表。
评估了 34 名打鼾（5.38±1.21 岁）和 66 名年龄和性别匹配的不打鼾（5.67±1.12 岁）学龄前儿童的日间和夜间睡眠时间、日间和夜间症状。打鼾组包括阻塞性睡眠呼吸暂停（OSA）评分<+3.5 和>-1 的儿童，不打鼾组的 OSA 评分<-1。
与不打鼾者相比，打鼾儿童的日间睡眠时间（51.62±28.9 分钟 vs. 10.70±20.2 分钟；p<0.001）存在差异，但夜间睡眠时间（10.97±0.52 小时 vs. 9.83±1.34 小时；p>0.05）无差异。打鼾组日间午睡的儿童比例高于不打鼾组（47.1% vs. 9.1%；p<0.00004），打鼾儿童的父母报告行为问题更为频繁（41.2% vs. 19.7%；p<0.02）。包括夜间（睡眠呼吸暂停）和日间症状（日间午睡和口腔呼吸）变量的多变量比值比表明，白天规律的睡眠是打鼾最具预测性的因素（OR=6.1；95%CI 1.76-21.04；p<0.005）。
在学龄前儿童中，当日间午睡开始消失时，打鼾可能会通过增加日间睡眠需求对日间时间表产生影响。
