背景：幼儿期是儿童睡眠模式发展的重要时期，对学龄前儿童睡眠模式的研究有助于阐明相关的心理/生理状况及以后睡眠问题的发生机制。目的和方法：本研究的目的和方法：本研究的目的是利用活动描记技术研究与学龄前儿童睡眠模式相关的内在和外在自变量。对来自两类托儿所的48名5岁儿童进行了为期7天的动态睡眠研究。结果：与平日相比，周末的儿童入睡时间和睡眠结束时间均较工作日晚(平均分别晚28分钟和17分钟)。在工作日，文化课与较晚的睡眠开始时间(晚22分钟)相关；女性、运动课和固定的洗澡时间与较早的睡眠结束时间(分别提前17、21和17分钟)相关；运动课与较高的睡眠效率(高3.7%)相关。在周末，不固定的就寝时间和白天小睡与较晚的睡眠开始时间相关(分别为73和54分钟)；男性、A型托儿所和白天小睡与较晚的睡眠结束时间(分别为33、37和34分钟)相关；运动课与较高的睡眠效率相关(高3.6%)。结论：性别、托儿、生活方式和托儿所课程等内在因素和外在因素都影响学龄前儿童睡眠模式的建立。对这些自变量的进一步研究可能有助于建立一种预测和预防晚年睡眠障碍的策略。(C)2010年综合业务数字网。爱思唯尔有限公司出版。保留所有权利。
Background: Early childhood is an important period for the development of sleep patterns; studies of sleep patterns in young preschool children may help elucidate the mechanism of associated mental/physical conditions and later sleep problems.Aim and methods: The aim of this study was to investigate intrinsic and extrinsic independent variables associated with sleep patterns in preschool children using actigraphy. Forty-eight 5-year-old children from two types of nurseries, which accommodate children with (Type A) or without (Type B) in-home caregivers, were invited to undergo a 7-day actigraphic sleep study.Results: Compared with weekdays, both sleep onset time and sleep end time were later on weekends (28 and 17 min later in average, respectively). On weekdays, cultural lessons were associated with a later sleep onset time (22 min later): female gender, sports lessons and fixed bathing times were related with an earlier sleep end time (17,21 and 17 min earlier, respectively); sports lessons were also associated with higher sleep efficiency (3.7% higher). During weekends, unfixed bedtimes and daytime naps were related with a later sleep onset time (73 and 54 min later, respectively); male gender, Type A nursery and daytime naps were associated with a later sleep end time (33,37 and 34 min later, respectively); sports lessons were associated with higher sleep efficiency (3.6% higher).Conclusions: Our current findings suggested that both intrinsic and extrinsic factors, such as gender, child care, lifestyle and after-nursery lessons, influence the establishment of sleep patterns in young preschool children. Further investigation of these independent variables may help establish a strategy for predicting and preventing sleep disorders later in life. (C) 2010 ISDN. Published by Elsevier Ltd.
