The subject consists of two groups. One group is 205 male adolescents enrolled in a junior high and senior high schools in northern area of Taichung city.

The other group is 94 male delinquents in Juvenile Correction Center of Taichung city. Multiple logistic regression analysis was used for each group to understand the correlates of physical violent behaviors. The results were as follows: 1) The rates of any types of violent behaviors of delinquent teens were higher than that of school teens；and the type of physical violence are significantly higher；2) for school teens, only biological factor—the history of head trauma was significantly influence the chance of having physical violent behavior and the odds ratio is 2.79；3) for delinquent teens, only biological factor—the level of cadmium in blood was significantly influence the chance of having physical violent behavior and its odds ratio is 3.24。This study suggested that one may give biological factors more weight than psychosocial factors when study the risk factors for having physical violent behaviors for male adolescents.
