Objective:
Our study aimed to verify whether cyberbullying victimization among adolescents occurs concomitantly with other forms of violence exposure (at home, at school and in the community).
Methods:
A collaborative longitudinal study by Norwegian and Brazilian researchers was conducted in Itaboraí, a low-income city in southeast Brazil. At baseline, trained interviewers applied a semi-structured questionnaire to a population-based sample of 669 in-school adolescents (11-15 years old). The investigated types of violence exposure included cyberbullying, traditional bullying, severe physical punishment by parents and community violence (victimization and eye-witnessed violent events outside the home and school).
Results:
In the previous six months, 1.9% of the adolescents had been victims of cyberbullying, and 21.9% had been victims of physical aggression, verbal harassment and/or social manipulation by peers. However, only 5.5% of the adolescents considered themselves bullying victims. In the previous 12 months, 12.4% of adolescents had suffered severe physical punishment, 14.0% had been victims of community violence, and 20.9% eye-witnessed community violence. Multivariable regression analysis showed that victimization by multiple types of traditional bullying and self-perceived bullying victimization were correlates of cyberbullying victimization, while suffering violence at home and in the community were not.
Conclusion:
This study provides evidence of an association between cyberbullying, traditional bullying and self-perceived bullying among low-income Brazilian adolescents.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
