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.

Technology-facilitated child sexual abuse (TF-CSA), or child sexual abuse that occurs online or through electronic communication, is a preventable public health problem that can be addressed within youth-serving organizations (YSOs). This study is a review of a purposive sample of organizational policies and practices designed to prevent TF-CSA collected from 13 national and local YSOs in the United States. Documents were coded to identify practices to prevent TF-CSA related to YSO activities or YSO staff, volunteers, or participants. Qualitative analysis indicated that YSOs included seven common practices to prevent TF-CSA in their documents. These practices included transparent electronic communication between youth and YSO staff; codes of conduct and online behavior agreements related to youth; monitoring the YSO's online presence; parental controls for youth online activity; safety behaviors for online activity for staff, parents, and youth; parent and youth trainings for youth online engagement and prevention of TF-CSA; and practices to address staff policy violations. Most prevention practices documented by YSOs identified in this study are consistent with emerging literature on TF-CSA prevention. Key gaps include protections for youth from groups inequitably burdened by TF-CSA and evaluation of the implementation and effectiveness of practices in preventing TF-CSA across settings and populations.
