美国高中生不良童年经历模式与每小时社交媒体使用情况：2023年青少年风险行为监测横断面分析

Adverse childhood experiences (ACEs) may be associated with adolescent social media engagement, but cumulative counts can obscure differences between co-occurring adversity patterns. We examined these associations in the 2023 national Youth Risk Behavior Survey (YRBS). We analyzed 9,603 students with complete data on eight ACE indicators, social media frequency and analysis covariates. The primary outcome was social media use at least hourly; the original threshold of at least several times a day was retained as a sensitivity outcome. Exploratory latent class analysis identified ACE profiles.
