Trends and sex disparities in school bullying victimization among U.S. youth, 2011–2017
Abstract Objectives The prevalence of being bullied traditionally among U.S. high school students is expected to reduce to 17.9%, according to Healthy People 2020 Initiatives. We examined trends in traditional and cyberbullying victimization with the latest large-scale time-series data in the United States. Methods We analyzed the data from the 2011-2017 national Youth Risk Behavior Survey (YRBS) to access the trends in traditional and cyberbullying among U.S. high school students. We identified the temporal trends using multivariate logistic regression analyses, accounting for survey design features of YRBS. Results The overall prevalence of victimization was 19.74% for traditional bullying and 15.38% for cyberbullying, suggesting that cyberbullying is not a low frequent phenomenon. The prevalence of victimization ranged from 20.19% to 19.04% for traditional bullying and 16.23% to 14.77% for cyberbullying, and the declined trends for the two kinds of bullying victimization were both statistically non-significant. The degree of overlap between the two kinds of bullying victimization was about 60%. Besides, female students experienced more traditional and cyberbullying than male peers within each survey cycle. Conclusions No declined trends in traditional and cyberbullying victimization were observed during 2011-2017. Female students are more likely to experience bullying. To achieve the Healthy People 2020 goal on bullying, more work is needed.
