There exist inconsistent findings about the relation between cosleeping and sleep problems in children. We conducted a meta-analysis to assess these relations and compared their cross-cultural differences. We searched the EMBASE, PsycARTICLES, PsycINFO, PubMed, ScienceDirect, and Web of Science databases. A random effect model was used, and subgroup analysis by culture group was performed. By including fifteen qualified studies, this meta-analysis revealed that increased bedtime resistance, sleep anxiety, night waking, and parasomnia were shown from children cosleeping with others. Cosleeping children from the West performed more bedtime resistance and night waking, while those children from the East showed more parasomnia. In general, cosleeping is associated with several sleep disturbances for children, including bedtime resistance, sleep anxiety, night waking, and parasomnia, and the cultural differences do exist between the West and East. The findings provide initial evidence of the influence of cosleeping on children’s sleep problems. More studies on the related topic are needed from diverse cultures in the future.

儿童共睡和睡眠问题：系统评价和荟萃分析

关于儿童共睡与睡眠问题之间的关系存在不一致的研究结果。我们进行了荟萃分析来评估这些关系并比较它们的跨文化差异。我们检索了 EMBASE、PsycARTICLES、PsycINFO、PubMed、ScienceDirect 和 Web of Science 数据库。采用随机效应模型，按培养组进行亚组分析。通过纳入 15 项合格研究，这项荟萃分析表明，与他人同睡的儿童会增加就寝时间抵抗、睡眠焦虑、夜醒和异态睡眠。来自西方的同睡儿童表现出更多的睡前抵抗力和夜醒，而那些来自东方的儿童则表现出更多的异态睡眠。一般来说，共睡与儿童的几种睡眠障碍有关，包括睡前抵抗、睡眠焦虑、夜醒和异态睡眠，东西方之间确实存在文化差异。研究结果为共睡对儿童睡眠问题的影响提供了初步证据。未来需要从不同文化中对相关主题进行更多研究。
