To survey the prevalence of bed- and room-sharing and assess associations with sleep/wake patterns, duration of sleep, and sleep problems among urban school-aged children in China.
Students representing eight Chinese cities were studied during November and December, 2005. A total of 19,299 elementary-school children (49.7% boys and 50.3% girls with a mean age of 9.00 years) participated in the survey. A parent-administered questionnaire and the Chinese version of the Children's Sleep Habits Questionnaire were completed to quantify children's sleep arrangements and to characterize sleep behaviors.
Co-sleeping was a common practice, with a prevalence of 37.6% (routine bed-sharing: 23.0%; room-sharing: 14.6%) in Chinese school-aged children. Bed- and room-sharing did not show significant gender difference but gradually decreased with increasing age. Compared to room-sharing and sleeping alone, bed-sharing was correlated with later bedtimes, later awakening times, and a shorter duration of sleep. However, the small difference was unlikely to have clinical significance. Bed- and room-sharing tended to be associated with the increased probability of six types of sleep problems: bedtime resistance, sleep anxiety, night waking, parasomnia, sleep-disordered breathing, and daytime sleepiness. Compared to bed-sharing, room-sharing had a lower odds ratio. Among six sleep problems, bedtime resistance and sleep anxiety had the strongest association with bed-sharing.
Sleep problems were common in Chinese school-aged children. Co-sleeping was highly prevalent and may be potentially associated with negative effects on sleep hygiene and sleep quality, although the context of the co-sleeping must be taken into consideration.
调查中国城市学龄儿童同床和同房睡眠的流行情况，并评估其与睡眠/觉醒模式、睡眠时间及睡眠问题之间的关联。
于2005年11月和12月对来自中国八个城市的学生进行研究。共有19299名小学生（男孩占49.7%，女孩占50.3%，平均年龄9.00岁）参与了此次调查。通过家长填写问卷及中文版儿童睡眠习惯问卷来量化儿童的睡眠安排并描述睡眠行为。
同床睡眠是一种常见现象，中国学龄儿童中同床睡眠的流行率为37.6%（常规同床：23.0%；同房：14.6%）。同床和同房睡眠在性别上无显著差异，但随年龄增长逐渐减少。与同房睡眠和独自睡眠相比，同床睡眠与更晚的就寝时间、更晚的起床时间及更短的睡眠时间相关。然而，这种微小差异不太可能具有临床意义。同床和同房睡眠往往与六种睡眠问题的发生概率增加有关：就寝抵抗（入睡困难）、睡眠焦虑、夜间觉醒、异态睡眠、睡眠呼吸障碍及日间嗜睡。与同床睡眠相比，同房睡眠的比值比更低。在六种睡眠问题中，就寝抵抗和睡眠焦虑与同床睡眠的关联最为密切。
睡眠问题在中国学龄儿童中很常见。同床睡眠非常普遍，可能对睡眠卫生和睡眠质量产生潜在负面影响，不过必须考虑同床睡眠的具体情况。
