Screen time, social media, and weight-related bullying are ubiquitous among adolescents. However, little research has been conducted among international samples. Therefore, the aim of this study was to determine the association between screen time, social media use, and weight-related bullying victimization among an international sample of adolescents from six countries. Data from the 2020 International Food Policy Study Youth Survey were analyzed (N = 12,031). Multiple modified Poisson regression models were estimated to determine the associations between weekday hours of five forms of screen time, and total screen time, and use of six contemporary social media platforms and weight-related bullying victimization. Analyses were conducted among the overall sample, and stratified by country (Australia, Canada, Chile, Mexico, United Kingdom, United States). Greater hours of weekday screen time and use of each of the six social media platforms were associated with weight-related bullying victimization among the sample. Each additional hour of social media use was equivalent to a 13% (confidence interval [CI] 1.10-1.16) increase in the prevalence of weight-related bullying victimization. The use of Twitter was associated with a 69% (CI 1.53-1.84) increase in the prevalence of weight-related bullying victimization. Associations between hours of weekday screen time, use of six social media, and weight-related bullying victimization differed by country. Findings underscore the associations between screen time, social media, and weight-related bullying among a sample of adolescents from six medium- and high-income countries. Country-specific and global public health and technology efforts are needed to address this burgeoning social problem.
屏幕时间、社交媒体和与体重相关的欺凌在青少年中普遍存在。然而，针对国际样本的研究却很少。因此，本研究的目的是确定来自六个国家的国际青少年样本中屏幕时间、社交媒体使用与与体重相关的欺凌受害之间的关联。分析了 2020 年国际粮食政策研究青年调查的数据（N=12031）。使用多个修正泊松回归模型来确定五种屏幕时间形式的工作日小时数和总屏幕时间以及使用六种当代社交媒体平台与与体重相关的欺凌受害之间的关联。在总体样本中以及按国家（澳大利亚、加拿大、智利、墨西哥、英国和美国）进行了分析。工作日屏幕时间增加和使用每种社交媒体平台都与样本中的与体重相关的欺凌受害有关。社交媒体使用每增加一小时，与体重相关的欺凌受害的流行率就会增加 13%（置信区间 [CI] 1.10-1.16）。使用 Twitter 与与体重相关的欺凌受害的流行率增加 69%（CI 1.53-1.84）有关。工作日屏幕时间、使用六种社交媒体与与体重相关的欺凌受害之间的关联因国家而异。研究结果强调了来自六个中高收入国家的青少年样本中屏幕时间、社交媒体与与体重相关的欺凌之间的关联。需要在国家和全球范围内采取公共卫生和技术措施来解决这一日益严重的社会问题。
