Objective. To describe the current situation of intentional injury among Vietnamese youth as well as risk and protective factors. Method. The Sample of Survey Assessment of Vietnamese Youth 2009 (SAVY2) involving 10 044 youth aged 14 to 25 in 2009 was used and compared with SAVY1 in this study. The data were analyzed using bivariate and multivariate statistical techniques. Results. Of the sample in 2009, 3% of the young people reported that they had been injured by a family member. The proportion who were intentionally injured by others outside their home was 7.6%. Youth who were most likely to hurt others included urban males, those who had ever been drunk, those who had been intentionally injured by others, and those who had weak family connectedness. Having suicidal thoughts (both sexes) is related to alcohol consumption. Conclusions. The rate of violent behaviors was low, but several risk and protective factors were found and confirmed.
