To understand the current situation of non-suicidal self-injury (NSSI) behavior among middle school students in Taiyuan, and to explore the relationship between socio-ecological risk factors and NSSI behavior of middle school students, so as to provide evidence for targeted intervention strategies.
A total of 2 635 middle and high school students in Taiyuan were selected by stratified random cluster sampling. The general demographic characteristics, the risk level of social ecology, and the occurrence of NSSI behavior in the past year were investigated. Binary Logistic regression was used to analyze the relationship between NSSI behavior and socio-ecological risk factors.
The reporting rate of NSSI behavior of middle school students was 13.5%. There were significant differences in NSSI behavior report rate among middle school students with different genders (χ2=11.12), the number of close friends (χ2=30.52), and different learning burden (χ2=37.51). After adjusting gender, the number of close friends, and learning burden factors (all P<0.01), the Logistic regression model took the low risk level of social and ecological risk factors as the control group, high risk personal factor (OR=2.93, 95%CI: 1.87-4.59), high risk family factor (OR=3.10, 95%CI: 2.04-4.71), moderate risk family factor (OR=2.08, 95%CI: 1.40-3.08), high risk school factors (OR=2.36, 95%CI:1.48-3.76), and high risk cultural factors (OR=1.44, 95%CI: 1.01-2.06) were positively correlated with NSSI behavior of middle school students.
When middle school students are exposed to high risk levels of individuals, families, schools and cultures in the social ecosystem, the risk of NSSI behavior will increase. While carrying on the intervention of personal, family and school factors, we should also pay attention to the influence of cultural factors on the NSSI of middle school students.
