Abstract: Background　Room sharing may affect sleep quality and cause a series of sleep disorders in children.Objective　To explore the prevalence and associated factors of sleeping in the same room with the guardian in primary school students，Guangzhou.Methods　Eligible participants were 2 462 students who were recruited from three key primary schools（including a provincial level，a municipal level and a district level）randomly extracted from the list of registered primary schools of Guangzhou in 2014.The revised Structural Sleep Questionnaire was used to survey the sleep status of these students in the past year，which includes five parts：basic information，family information，parental information，sleep problems and whether usually sleep alone in a room.The questionnaire was distributed to the students，and was completed by the students with their parents at home and was returned within one week.According to the survey results，they were divided into non-cosleeping group and cosleeping group.Results　Altogether，2 345（95.2%）cases〔consisting of 1 218 males and 1 127 females with an average age of（9.5±1.7）years old〕 effectively responded to the survey，including 1 217（51.9%）co-sleepers and 1 128（48.1%）non-co-sleepers.The differences in average age，prevalence of one-year regular medication，single-parent family，sleeping environment，living area and average monthly family income between two groups reached significant level（P<0.05）.The prevalence of sleeping in the same room with the guardian among children aged 7-14 years decreased over years（χ2trend=30.91，P<0.01）.The average maternal age and paternal age of the non-cosleeping group were older than those of the cosleeping group（P<0.05）.The prevalence of maternal difficulties in getting up in the morning had significant intergroup difference（P<0.05）.The intergroup differences in paternal education level，prevalence of paternal dry mouth in the morning，sleep terror，difficulty in getting up in the morning，frequent sweating，drowsiness in daytime，sleeping difficulty，early morning headache，and non-refreshing sleep were significant（P<0.05）.The prevalence of snoring，sleep terror，difficulty in getting up in the morning，frequent sweating，frequent rolling over in sleep，drowsiness in daytime，special prone sleeping position，grinding teeth during sleep，bed-wetting and sleep talking differed significantly between the groups（P<0.05）.Multivariate Logistic regression analysis revealed that age〔OR=0.713，95%CI（0.659，0.772）〕，single-parent family〔OR=1.348，95%CI（1.098，1.655）〕，snoring〔OR=1.115，95%CI（1.020，1.219）〕，living area〔OR=0.908，95%CI（0.826，0.997）〕 were associated with sleeping in the same room with the guardian（P<0.05）.Conclusion　Sleeping in the same room with the guardian is relatively common（51.9%）in primary school students，Guangzhou，which is associated with younger age，single-parent family，snoring，and small living area.

摘要： 背景　儿童同房间共眠可能影响其睡眠质量，并引发一系列睡眠问题。目的　调查广州市小学生同房间共眠状况，并分析其影响因素。方法　根据广州市登记在册的小学名单，2014年应用随机数字法抽取1所省重点、1所市重点和1所区重点小学符合研究标准的2 462名在校小学生为研究对象。采用定式化睡眠问卷调查小学生最近1年的睡眠状况，问卷包括5部分：基本资料、家庭资料、父母资料、睡眠问题及儿童通常是否自己睡一间房？并依据最后一部分结果将儿童分为非共眠组和共眠组。问卷经学生带回家后与家长一起完成填写，1周内交回。结果　共发放调查问卷2 462份，回收有效问卷2 345份，有效回收率为95.2%。2 345名小学生中，男1 218名，女1 127名；年龄（9.5±1.7）岁；共眠1 217名（51.9%），非共眠1 128名（48.1%）。两组儿童年龄、近1年规律服药情况、单亲家庭情况、就寝环境、居住面积情况、家庭月收入情况比较，差异有统计学意义（P<0.05）。7~14岁儿童同房间共眠发生率随年龄增长而降低（χ2趋势=30.91，P<0.01）。非共眠组儿童母亲、父亲年龄均大于共眠组（P<0.05）；两组儿童母亲不愿晨起情况比较，差异有统计学意义（P<0.05）；两组儿童父亲文化程度、晨起口干、惊醒、不愿晨起、经常流汗、日间困倦、入睡困难、晨起头痛、睡眠感缺失情况比较，差异有统计学意义（P<0.05）。两组儿童打鼾、惊醒、不愿晨起、经常流汗、经常翻身、日间困倦、特殊俯睡体位、磨牙、尿床、呓语情况比较，差异有统计学意义（P<0.05）。多因素Logistic回归分析结果显示，年龄〔OR=0.713，95%CI（0.659，0.772）〕、单亲家庭〔OR=1.348，95%CI（1.098，1.655）〕、儿童打鼾〔OR=1.115，95%CI（1.020，1.219）〕、居住面积〔OR=0.908，95%CI（0.826，0.997）〕是小学生发生同房间共眠的影响因素（P<0.05）。结论　广州市小学生与其家人同房间共眠状况较普遍（51.9%），低龄、单亲家庭、儿童打鼾、居住面积小是其同房间共眠的重要影响因素。
