Abstract

Purpose
Bullying victimization among adolescents is a major public health concern. However, multicountry studies investigating temporal trends of bullying victimization among adolescents are scarce, especially from a global perspective. Thus, we aimed to examine the temporal trends of bullying victimization among school-going adolescents between 2003 and 2017 in 29 countries from Africa (n = 5), Asia (n = 18), and the Americas (n = 6).

Methods
Data on 191,228 students aged 12–15 years [mean (standard deviation) age 13.7 (1.0) years; 48.9% boys] who participated in the Global School-based Student Health Survey were analyzed. Bullying victimization was based on self-report and referred to being bullied at least once in the past 30 days. The prevalence (95% confidence interval) of bullying victimization was calculated for each survey. Crude linear trends in bullying victimization were examined by linear regression models.

Results
The mean prevalence of bullying victimization across all surveys was 39.4%. There was a large variation in the trends of bullying victimization across countries with a significant increasing and decreasing trend being observed in 6 and 13 countries, respectively. Myanmar, Egypt, and the Philippines showed the sharpest increase. The decrease was modest in most countries which showed a decreasing trend. The remaining countries showed stable trends (n = 10) but some countries such as Seychelles showed consistently high prevalence over time (i.e., ≥ 50%).

Discussion
Decreasing trends of bullying victimization were more common than increasing or stable trends in our study including adolescents from 29 countries. However, a high prevalence of bullying was observed in most countries, and thus, further global efforts to combat bullying victimization are necessary.
