Objective This paper aimed to report the rate of suicide attempts among adolescent and young students of eight cities in China, and to examine the impact of related psychosocial factors on suicide attempts. Methods The investigation was obtained in senior and junior high school and college students in eight cities of China. All of the 17 622 participants were recruited to complete anonymous questionnaires regarding their experiences of suicide attempts and related psychosocial factors. Results Overall, 2.2 percent of the respondents reported that they had experienced attempted suicide during the previous year. Scores on high anxiety （OR=2.61,95%CI： 1.64-4.16） ,high depression （OR=2.05, 95%CI： 1.35-3.10）,suicide idea （OR=14.21, 95%CI： 9.88-20.43 ）, suicide plan （OR = 3.50,95%CI： 2.59-4.73 ） were revealed as common risk factors while the whole time span being accompanied by mothers during juvenile years （OR=0.38, 95% CI： 0.20-0.74） seemed to be protective factor for suicide attempts through multivariate logistic regression analysis. Conclusion Our results showed that emotional symptom, idea and plans for suicide were statistically associated with suicide attempted in high school and college students.
