464 Analysis on the incidence and relevant risk factors of school violence among migrant, left-behind, and ordinary school adolescents in China

Background

School violence is a leading cause of death among adolescents. A number of studies indicate that numerous influencing factors of violence in adolescents, but less is known about the role of migrant, left-behind, and ordinary (non migrant and non left-behind) school adolescents in China. The aim of this study was to examine the violence relevant risk factors in this population.

Methods

This study choosing a stratified cluster sample method in proportion, 5,158 adolescents of seven grades, spanning 3^th to 5^th grade (four primary schools), 7th to 8th (four junior high schools), 10th to 11th (two senior high schools) involved in the investigation. Data on the occurrence of influencing factors were tested using binary logistic regression for their association between suffered and exerted violence among school adolescents.

Results

The survey indicated that the incidence of suffered violence among migrant, left-behind, and ordinary school adolescents is 10.51%, 18.40%, 11.33%, and the incidence of exerted violence is 6.54%, 8.96%, 5.76% in the past six months. There are differences of the status of suffered violence among different types of school adolescents, left-behind school adolescents had high incidence of suffered violence (P = 0.002). The binary logistic regression revealed that male, poor family relationship, smoking, father's low educational, moderate and severe degree of being bullied were the risk factors of suffered violence in migrant children. Risk factors of left-behind children were moderate and severe degrees of being bullied. Risk factors of ordinary children were male, primary school adolescents, poor family relationship, moderate and severe degree of being bullied. Primary school adolescents, mother smoking, smoking, drinking, poor school performance, poor family relationship, moderate and severe degree of being bullied were the risk factors of exerted violence in migrant children. Risk factors of left-behind children were severe degree of being bullied, not single-child and father's occupation was manager. Risk factors of ordinary children were male, primary school adolescents, not single-child, poor family relationship, moderate and severe degree of being bullied.

Conclusion

Our research indicates that numerous risk factors are related to suffer and exert violence among school adolescents. Prevention of school violence can best involve strategies that focus on individuals in known high-risk groups and strategies aimed at general reduction in population risk of violence.
