bstract: 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 (OR = 1.886, 95% CI = 1.723-2.065, OR = 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.
非自杀性自伤（NSSI）在青少年中较为普遍。健康素养（HL）水平低和手机使用问题（PMPU）是 NSSI 的风险因素。但迄今为止，尚无研究探讨 HL 和 PMPU 之间的交互作用对 NSSI 的影响。在这种情况下，本研究旨在检验 HL 和 PMPU 的相互作用及其对中国青少年群体中 NSSI 的影响。共纳入 22628 名初中和高中生（男生 10990 名，女生 11638 名）参与本研究。研究结果为自我报告的 HL、PMPU 和 NSSI。采用卡方检验和逻辑回归模型进行分析。NSSI 的患病率为 32.1%。HL 水平低和 PMPU 与 NSSI 独立相关（OR=1.886，95%CI=1.723-2.065，OR=2.062，95%CI=1.934-2.199）。交互作用分析表明，HL 水平低和 PMPU 与 NSSI 的风险增加呈交互作用（OR=2.617，95%CI=2.375-2.884）。总之，我们的研究结果表明，HL 和 PMPU 与 NSSI 独立相关，并且存在交互作用。NSSI 的干预计划应考虑青少年的 HL 水平和 PMPU。
