Abstract:
Objective:To explore the relationship between dieting and binge eating with non suicidal self-injury (NSSI) among secondary vocational school students, so as to provide a scientific basis for the development of effective interventions to prevent NSSI.
Methods:From October to December 2023, 2 364 students were selected by stratified cluster random sampling method from nine secondary vocational schools in Guizhou Province to conduct a self administered questionnaire survey. Unconditional binary Logisitic regression was used to analyze the relationship between dieting, binge eating behaviours, and the co-occurrence of the two and NSSI among secondary vocational school students, and were stratified by sex.
Results:The detection rate of NSSI among secondary vocational school students in Guizhou Province was 27.5%, 6.8% of secondary vocational school students reported dieting, 10.5% reported binge eating behaviour, and 2.9% showed both dieting and binge eating behaviours. The adjusted model of unconditional binary Logistic regression showed that the presence of dieting ( OR =2.37), binge eating behaviour ( OR =2.31), and the co-occurrence of both ( OR =2.60) were associated with higher risk of NSSI among secondary vocational school students; stratified analysis by gender showed that both males and females with dieting, binge eating and coexistence of dieting and binge eating behaviours were at increased risk of NSSI (females: OR =2.27, 2.26, 2.78 ; males: OR =2.15, 2.08, 2.02) ( P <0.01).
Conclusions:Dieting and binge eating behavior of secondary vocational school students will increase the risk of NSSI. When preventing and intervening NSSI problems of secondary vocational school students, it should pay more attention to eating habits.
