Social media has become a pervasive presence in everyday life, including among youths. In 2023, for the first time, CDC's nationally representative Youth Risk Behavior Survey included an item assessing U.S. high school students' frequency of social media use. Data from this survey were used to estimate the prevalence of frequent social media use (i.e., used social media at least several times a day) among high school students and associations between frequent social media use and experiences with bullying victimization, persistent feelings of sadness or hopelessness, and suicide risk. All prevalence estimates and measures of association used Taylor series linearization. Prevalence ratios were calculated using logistic regression with predicted marginals. Overall, 77.0% of students reported frequent social media use, with observed differences by sex, sexual identity, and racial and ethnic identity. Frequent social media use was associated with a higher prevalence of bullying victimization at school and electronically, persistent feelings of sadness or hopelessness, and some suicide risk among students (considering attempting suicide and having made a suicide plan), both overall and in stratified models. This analysis characterizes the potential harms of frequent social media use for adolescent health among a nationally representative sample of U.S. high school students. Findings might support multisectoral efforts to create safer digital environments for youths, including decision-making about social media policies, practices, and protections.
社交媒体已经成为日常生活中无处不在的存在,包括在年轻人中。2023 年,美国疾病控制与预防中心(CDC)首次在全国代表性的青少年风险行为调查中纳入了一项评估美国高中生社交媒体使用频率的项目。本调查数据用于估计经常使用社交媒体(即每天至少使用几次社交媒体)的高中生的比例,以及频繁使用社交媒体与遭受欺凌受害、持续悲伤或绝望感以及自杀风险之间的关联。所有流行率估计和关联测量均采用泰勒级数线性化。使用逻辑回归和预测边缘计算流行率比。总体而言,77.0%的学生报告经常使用社交媒体,其差异与性别、性认同以及种族和民族认同有关。频繁使用社交媒体与在学校和电子环境中遭受欺凌受害、持续悲伤或绝望感以及一些自杀风险(考虑自杀未遂和制定自杀计划)的发生率较高有关,无论是整体上还是在分层模型中。本分析描述了经常使用社交媒体对美国代表性的高中生青少年健康的潜在危害。研究结果可能支持多部门努力为年轻人创造更安全的数字环境,包括制定社交媒体政策、实践和保护措施的决策。
