2010年，8-18岁的美国年轻人平均每天花7.5小时在娱乐媒体上，比2005年增加了一个多小时。媒体使用的增加与多种负面结果有关，包括睡眠时间减少和疲劳增加，但很少有研究调查媒体使用是否与个人实际睡眠效率下降有关。这项研究评估了青少年媒体使用与睡眠效率之间的关系。55名青少年（平均年龄=14.89岁，SD=0.62； 53%非裔美国人，47%白种人）完成了关于媒体使用的自我报告测量。通过活动记录仪测量一周的睡眠质量，并从活动记录仪数据中提取睡眠偏移量和睡眠效率。睡眠效率与每天发短信的时间（r(52)= - 0.29, p< 0.05）、睡前使用媒体的时间（r(52)= - 0.32, p< 0.05）和夜间被手机唤醒的次数（r(52)= - 0.33, p< 0.05）呈负相关。睡眠效率下降与早上睡得晚有关，可能是为了弥补晚上失去的睡眠（r(52)= - 0.33, p< 0.05）。在回归模型中，媒体使用占睡眠效率方差的30% （Adj. R2=0.30， F(6,44)=3.74, p<0.01）。睡前使用媒体、晚上被手机吵醒以及睡眠偏移与青少年睡眠效率相关。结果支持将媒体使用习惯纳入青少年睡眠健康教育和睡眠功能障碍干预。父母教育媒体使用对睡眠的影响也可以减轻负面影响。
In 2010, American youth ages 8-18 spent an average of 7½ hours daily using entertainment media, an increase of more than an hour compared to 2005. Increase in media use is associated with multiple negative outcomes, including decreased sleep time and increased tiredness, but little research has examined whether media use is associated with poorer sleep efficiency when the individual is actually asleep. This study assessed relationships between adolescent media use and sleep efficiency. Fifty-five adolescents (mean age=14.89 years, SD=0.62; 53% African-American, 47% Caucasian) completed self-report measures concerning their media use. Sleep quality was measured by actigraphy for one week, and both sleep offset and sleep efficiency were extracted from actigraphy data. Sleep efficiency was negatively correlated to daily time spent text messaging (r(52)=−0.29, p<.05), media use after bed (r(52)=−0.32, p<.05), and number of nighttime awakenings by mobile phones (r(52)=−0.33, p<.05). Decreased sleep efficiency was related to sleeping later in the morning, presumably to make up for lost sleep at night (r(52)=−0.33, p<.05). In a regression model, media use accounted for 30% of the variance in sleep efficiency (Adj. R2=0.30, F(6,44)=3.74, p<0.01). Media use after bed, awakenings by a mobile phone at night and sleep offset associated with adolescents’ sleep efficiency. Results support the incorporation of media use habits into adolescent sleep health education and sleep dysfunction interventions. Parental education about the effects of media use on sleep could also mitigate negative effects.
