摘　　要： 目的了解深圳市中学生非自杀性自伤行为(NSSI)的流行特征及影响因素,为干预和预防NSSI提供科学依据。方法采用分层整群抽样的方法,对深圳市10所学校中学生进行问卷调查,调查内容包括一般情况和伤害行为,利用c2检验和非条件多因素logistic回归等方法分析中学生NSSI的发生情况及其影响因素。结果共调查3 737名学生,包括2 033名男生和1 704名女生,男女比例为1.19∶1。调查对象包括初一至高三学生,平均年龄为15岁。过去1年内深圳市中学生NSSI发生率为34.7%。非条件多因素logistic回归分析显示,11～16岁年龄段的学生NSSI发生率较其他年龄段高(OR=1.220),发生过外伤比不发生外伤者NSSI发生率高(OR=1.788),学习日住校学生NSSI发生率比不住校学生低(OR=0.724),有关系亲密的朋友的学生NSSI发生率较低(OR=0.804)。结论深圳市中学生NSSI发生率较高,应及早发现并根据相关影响因素采取干预措施,减少和预防NSSI的发生。 Objective To investigate epidemiological characteristics and factors influencing non- suicidal self-injury （NSSI） behaviors among middle school students in Shenzhen and to provide scientific evidence for its intervention and prevention. Methods A stratified cluster sampling method was used to select middle school students from 10 schools in Shenzhen for questionnaire survey. The survey content in- cluded general conditions and injury behavior. A Chi-square test and logistic regression were used for data analysis. Results A total of 3 737 students, including 2 033 boys and 1 704 girls, were surveyed, and the ratio of males to females was 1.19： 1. The average age of the participants was 15 years old. In the past year, the prevalence rate of NSSI among middle school students in Shenzhen was 34.7%. Unconditional multivariate logistic analysis showed that the NSSI level of students aged 11-16 years was higher than that of the other age groups （OR = 1.220）, the students with trauma had higher NSSI level than those without trauma （OR = 1.788）, the NSSI level of students living on campus was lower than that of students not liv- ing on campus （OR = 0.724）, and the incidence of NSSI among students with close friends was lower （OR = 0.804）. Conclusions The prevalence rate of NSSI among middle school students in Shenzhen was high. Early detection of NSSI and interventions based on relevant influencing factors should be taken to re- duce and prevent the occurrence of NSSI.
