Objective To identify the factors associated with bullying behaviors among adolescents by analyzing victims, aggressors and victims/aggressors separately. Methods A cross-sectional study was performed in a representative sample of 3,089 secondary school students (13-18 years old) in Barcelona (Spain). To define bullying behaviors, we used three questions about different types of mistreatment (jeering, attacking, marginalizing). Results Compared with secondary school students not involved in bullying, victims, aggressors and victims/aggressors were more likely to be boys and to report negative mood states. Victims were younger, were more overweight or obese and were lighter cannabis users, while aggressors were also younger but reported more antisocial behaviors and more cannabis and alcohol use. Victims/aggressors reported more antisocial behaviors and were overweight. Conclusions Being involved in bullying, independently of the role adopted, was associated with health-related problems, which can lead to psychological disorders in adulthood.
