This study aimed to investigate (1) access to screens and screen use in the hour before bedtime and in bed; (2) attitudes and barriers to reducing screen time, and (3) perceptions of potential interventions to reduce screen time to benefit the sleep of New Zealand adolescents.
Adolescents (aged 13-17 years, n = 4,811) living in New Zealand were recruited online between November 2015 and March 2016 with a direct link to complete a questionnaire about screen use in the hour before bedtime (including the types of screens used and activities) and screen use when in bed. Sleep patterns and quality were measured, and attitudes to reducing screen time using potential interventions were explored.
The most common prebedtime screen activities reported on most nights were social media (88%) and texting/instant messaging (77%). The majority of participants reported they used phones in bed (86%) and "agreed" they spent too much time on screens (70%), a perception that increased with age (p = .008). Being unable to communicate with friends was the most common barrier to reducing screen time (67% agreed).
Screen use in adolescents is complex; however, there is scope to improve sleep by reducing the impact of in-bed use of portable devices and addressing barriers to reduce screen time in adolescents.
本研究旨在调查：（1）在睡前一小时和卧床期间接触屏幕和使用屏幕的情况；（2）减少屏幕时间的态度和障碍；（3）为改善新西兰青少年睡眠而减少屏幕时间的潜在干预措施的看法。
2015 年 11 月至 2016 年 3 月，通过直接链接在线招募了居住在新西兰的青少年（13-17 岁，n=4811 人），以完成一份关于睡前一小时（包括使用的屏幕类型和活动）和卧床时使用屏幕情况的调查问卷。还测量了睡眠模式和质量，并探讨了使用潜在干预措施减少屏幕时间的态度。
报告大多数晚上最常见的睡前屏幕活动是社交媒体（88%）和短信/即时消息（77%）。大多数参与者报告说他们在床上使用手机（86%），并“同意”他们在屏幕上花费了太多时间（70%），这种看法随着年龄的增长而增加（p=0.008）。无法与朋友交流是减少屏幕时间的最常见障碍（67%的人同意）。
青少年的屏幕使用情况很复杂；然而，通过减少卧床时使用便携式设备的影响和解决青少年减少屏幕时间的障碍，有改善睡眠的空间。
