Abstract

Non-suicidal self-injury (NSSI) is prevalent among adolescents. Low health literacy (HL) and problematic mobile phone use (PMPU) are risk factors of NSSI. But so far, no study has examined the interactive role of HL and PMPU on NSSI. In this context, the present study aimed to examine the interactions of HL and PMPU and their impact on NSSI in a school-based sample of Chinese adolescents. A total of 22,628 junior and high school students (10,990 males and 11,638 females) were enrolled in this study. The outcomes were self-reported HL, PMPU and NSSI. Analyses were conducted with chi-square tests and logistic regression models. The prevalence of NSSI was 32.1%. Low HL and PMPU were significantly associated with NSSI independently (ORlowHL = 1.886, 95% CI = 1.723-2.065, ORPMPU = 2.062, 95% CI = 1.934-2.199). Interaction analysis indicated that low HL and PMPU were interactively associated with increased risks of NSSI (OR = 2.617, 95% CI = 2.375-2.884). In all, our findings indicate that HL and PMPU are associated with NSSI independently and interactively. The intervention programs of NSSI should consider the adolescents HL levels and PMPU.
