Associations between screen time and health outcomes among teenagers are well established. However, most studies use parent-reported information, which may misrepresent the magnitude or nature of these associations. In addition, timely nationally representative estimates are needed to correspond with evolving screen use. This study aimed to address these gaps by using data from a nationally representative survey of teenagers.
Data came from the 2021-2023 National Health Interview Survey-Teen (NHIS-Teen), a follow-back web-based survey designed to collect health information directly from teenagers aged 12 to 17 years. NHIS-Teen provides a unique opportunity to assess teenagers' self-reported health in conjunction with a rich set of parent-reported covariates, including family income, from the National Health Interview Survey. This study examines associations between high daily non-schoolwork screen time, defined as 4 or more hours of daily screen time, and adverse health outcomes across the domains of physical activity, sleep, weight, mental health, and perceived support.
Teenagers with higher non-schoolwork screen use were more likely to experience a series of adverse health outcomes, including infrequent physical activity, infrequent strength training, being infrequently well-rested, having an irregular sleep routine, weight concerns, depression symptoms, anxiety symptoms, infrequent social and emotional support, and insufficient peer support.
Results of this study include associations between high screen time and poor health among teenagers using self-reported data. Future work may further investigate these associations and their underlying mechanisms, including the content viewed on screens and the interactions taking place across screens.
青少年的屏幕使用时间与健康结果之间的关联已得到充分证实。然而，大多数研究使用的是家长报告的信息，这可能会歪曲这些关联的程度或性质。此外，需要及时的全国代表性估计，以跟上屏幕使用情况的变化。本研究旨在通过使用全国代表性青少年调查的数据来填补这些空白。
数据来自2021 - 2023年全国青少年健康访谈调查（NHIS - Teen），这是一项基于网络的回溯性调查，旨在直接收集12至17岁青少年的健康信息。NHIS - Teen提供了一个独特的机会，可结合一系列丰富的家长报告协变量（包括来自全国健康访谈调查的家庭收入）来评估青少年自我报告的健康状况。本研究考察了每日非课业屏幕使用时间较长（定义为每日屏幕使用时间4小时或更长）与身体活动、睡眠、体重、心理健康和感知支持等领域的不良健康结果之间的关联。
非课业屏幕使用时间较长的青少年更有可能经历一系列不良健康结果，包括身体活动不频繁、力量训练不频繁、休息不足、睡眠不规律、体重问题、抑郁症状、焦虑症状、社交和情感支持不频繁以及同伴支持不足。
本研究结果包括使用自我报告数据得出的青少年屏幕使用时间长与健康状况不佳之间的关联。未来的研究可以进一步调查这些关联及其潜在机制，包括在屏幕上观看的内容以及屏幕之间发生的互动。
