To describe daytime naps and nighttime sleep-wake patterns in children attending full-day childcare centers.
A descriptive cross-sectional study of sleep and daytime nap patterns in 52 healthy children 3-5 years of age. Sleep and nap data were obtained over 3 days and nights (Tuesday, Wednesday, and Thursday) with continuous ankle actigraphy recording on children attending two university-affiliated childcare centers.
Children averaged about 10 hr (610 min +/- 38 SD) of total sleep in 24 hr, as estimated by actigraphy. For the 41 children who napped, average nap duration was 75.8 min (+/-20 SD). Nocturnal sleep was less for children who napped (9.0 hr +/- 0.71 SD) compared to those who did not nap (9.8 hr +/- 0.53 SD).
Findings indicate that the majority of 3-to-5-year-old children nap when given an opportunity. Preschool children's sleep and napping patterns on weekends and in other types of childcare environments warrant further research to assess health effects and impact on growth and development.
描述全日制儿童保育中心儿童的日间小睡和夜间睡眠-觉醒模式。
对52名3至5岁健康儿童的睡眠和日间小睡模式进行描述性横断面研究。通过连续的脚踝活动记录仪记录，在两天两夜（周二、周三和周四）收集两所大学附属儿童保育中心儿童的睡眠和小睡数据。
通过活动记录仪估计，儿童24小时的总睡眠时间平均约为10小时（610分钟±38标准差）。对于41名小睡的儿童，平均小睡时长为75.8分钟（±20标准差）。与不午睡的儿童相比，午睡儿童的夜间睡眠时间较短（9.0小时±0.71标准差），而非午睡儿童为（9.8小时±0.53标准差）。
研究结果表明，大多数3至5岁的儿童在有机会时会午睡。学龄前儿童在周末以及其他类型儿童保育环境中的睡眠和小睡模式，有待进一步研究以评估其对健康的影响以及对生长发育的作用。
