  METHODS
  2200 college students in three universities in Guangzhou were selected by cluster sampling method and were interviewed with self-designed questionnaire about the incidence and risk factors of campus violence in 2010. The final analysis sample was 2103. Chi-square test was used to analyze the gender, grade and major distribution of campus violence. Logistic regression method was used to analyze the influencing factors of campus violence in bully and victim.
  
  
  RESULTS
  The incidence of campus violence in Guangzhou was 69.9% (1471/2103). In boys and girls the incidence of campus violence was 75.6% (830/1098) and 63.8% (641/1005) (χ(2) = 34.82, P < 0.05). The incidence of bully and victim of campus violence was 63.6%(1338/2103) and 55.3% (1163/2103). The incidence of bully and victim in boys was 70.9%(778/1098) and 60.0%(659/1098), and in girls was 55.7% (560/1005) and 50.1% (504/1005) (χ(2)(bully) = 51.93, χ(2)(victim) = 20.68, P < 0.01). The incidence of psychological violence was the highest (68.0%, 1430/2103), followed by sexual violence (34.2%, 719/2103), the incidence of physical violence was the lowest (16.5%, 348/2103). Results of logistic regression showed that boys (OR = 1.60), arts (OR = 1.82), with siblings (OR = 1.31), the living expenses was not enough (basic enough OR = 1.35, not enough OR = 1.54), playing the computer games (OR = 1.70), playing tricks such as sliding plate (OR = 2.03), loving violence program (general OR = 1.30, very like OR = 1.44), mother with gamble behavior (OR = 4.29), father's indulgent education style (OR = 1.60), been bullied by others before high school (OR = 1.61), dissatisfaction to the environment and rules of campus (nothing special feeling OR = 1.67, some dissatisfaction OR = 1.89), been treated badly by primary school teacher (one kind OR = 1.35, two kinds and above OR = 1.90)were the risk factors of bully. Boys (OR = 1.23), minority (OR = 1.71), with siblings (OR = 1.39), bad behavior and habit (OR = 1.32), the bad family economic conditions (general OR = 1.51, difficult OR = 1.88), mother with gamble behavior (OR = 2.33), father's indulgent education style (OR = 1.37), occasional physical punishment by mother (OR = 1.35), been bullied by others before high school (sometimes OR = 1.61, often OR = 1.85), high pressure during the study (a little high OR = 1.37, very high OR = 1.40), dissatisfaction to the environment and rules of campus (some dissatisfaction OR = 1.56, completely dissatisfaction OR = 2.04), been treated badly by primary school teacher (one kind OR = 1.70, two kinds and above OR = 2.04)were the risk factors of being victim.
