To determine the amount of television viewing and computer use in urban school-aged Chinese children, and to examine their associations with sleep/wake patterns, duration of sleep, and sleep disorders.
Students representing 8 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 media use and to characterize sleep patterns and sleep disturbances.
A television or computer was present in the bedroom of 18.5% and 18.3% of Chinese school-aged children, respectively. Media presence in the bedroom and media use were positively correlated with later bedtimes, later awakening times, and a shorter duration of sleep during weekdays and weekends. They were also significantly associated with at least 2 types of sleep disturbances. Overall, the most affected sleep behaviors were bedtime and awakening time on the weekends, the duration of sleep during the weekdays, and sleep disorders of bedtime resistance and sleep anxiety. Television viewing > or = 2 hours/day on weekends, with a prevalence of 48.8%, was the predominant risk factor for all sleep disorders with the exception of the sleep duration disorder. Computer use, however, had no correlation with any sleep disorder.
The presence of media in a child's bedroom and media use had a negative effect on children's sleep/wake patterns, duration of sleep, and sleep disorders.
确定中国城市学龄儿童看电视和使用电脑的时间，并研究其与睡眠/觉醒模式、睡眠时间及睡眠障碍之间的关联。
2005年11月至12月对来自中国8个城市的学生进行了研究。
共有19299名小学生参与了调查，其中男生占49.7%，女生占50.3%，平均年龄为9.00岁。
通过家长填写问卷以及使用中文版儿童睡眠习惯问卷来量化媒体使用情况，并描述睡眠模式和睡眠障碍。
分别有18.5%和18.3%的中国学龄儿童卧室里有电视或电脑。卧室中媒体设备的存在及媒体使用情况与工作日和周末较晚的就寝时间、较晚的起床时间以及较短的睡眠时间呈正相关。它们还与至少两种类型的睡眠障碍显著相关。总体而言，受影响最大的睡眠行为是周末的就寝时间和起床时间、工作日的睡眠时间以及就寝抗拒和睡眠焦虑等睡眠障碍。周末每天看电视≥2小时的情况最为普遍，患病率为48.8%，是除睡眠时间障碍外所有睡眠障碍的主要危险因素。然而，使用电脑与任何睡眠障碍均无关联。
儿童卧室中媒体设备的存在及媒体使用对儿童的睡眠/觉醒模式、睡眠时间及睡眠障碍有负面影响。
