INTRODUCTION
This report describes the self-reported prevalence of daily screen time among teenagers ages 12-17 years and explores whether differences exist by selected characteristics and demographics.
METHODS
Data from the July 2021-December 2023 National Health Interview Survey-Teen were used for this analysis. Point estimates and the corresponding confidence intervals were calculated using SAS-callable SUDAAN software to account for the complex sample design of NHIS-Teen. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.
KEY FINDINGS
During July 2021-December 2023, about one-half of teenagers had 4 hours or more of daily screen time (50.4%). Black non-Hispanic teenagers (60.4%) were most likely to have 4 hours or more of daily screen time compared with teenagers in other race and Hispanic origin groups. About 1 in 4 teenagers with 4 hours or more of daily screen time have experienced anxiety (27.1%) or depression symptoms (25.9%) in the past 2 weeks.
引言
本报告描述了12至17岁青少年自我报告的每日屏幕使用时间流行情况，并探讨了根据选定特征和人口统计学因素是否存在差异。
方法
本分析使用了2021年7月至2023年12月全国青少年健康访谈调查的数据。使用SAS可调用的SUDAAN软件计算点估计值和相应的置信区间，以考虑全国青少年健康访谈调查的复杂样本设计。使用双侧显著性检验在0.05水平评估百分比之间的差异。
主要发现
在2021年7月至2023年12月期间，约一半青少年每日屏幕使用时间为4小时或更长时间（50.4%）。与其他种族和西班牙裔血统群体的青少年相比，非西班牙裔黑人青少年（60.4%）最有可能每日屏幕使用时间为4小时或更长时间。在过去2周内，每日屏幕使用时间为4小时或更长时间的青少年中，约四分之一曾经历焦虑（27.1%）或抑郁症状（25.9%）。
