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.
