摘　　要：目的了解小学生视屏时间与自我伤害行为的关联,为制定小学生自我伤害行为预防提供依据。方法采用分层随机整群抽样方法,于2017年6—11月选取浙江、广东、江西、四川、贵州5省1 090名小学生进行问卷调查,分析视屏时间和自我伤害行为的关联。结果 5.6%的小学生每天视屏时间>2 h,男生、农村学生、健康素养较低的学生、饮酒的学生每天视屏时间过长,差异均有统计学意义(χ2值分别为12.35,6.94,6.86,16.86,P值均<0.05),每周零花钱不同的学生视屏时间分布不同(P<0.01)。11.3%的小学生有过自我伤害行为,西部地区、男生、三年级、农村、监护人为其他成年亲属、健康素养较低、吸烟、饮酒、每天视屏时间>2 h的学生自我伤害行为发生率较高,差异均有统计学意义(χ2值分别为27.31,11.49,23.91,22.12,15.11,55.16,19.03,25.16,19.35,P值均<0.05)。多因素Logistic回归分析结果显示,与视屏时间≤2 h的学生相比,视屏时间>2 h的学生自我伤害行为较高(OR=2.62,95%CI=1.31~5.23)。结论小学生自我伤害行为与视屏时间有关,应在小学生中开展减少视屏时间的健康教育工作。Objective To explore the association of screen time with self-injury behavior in primary school students in China, to provide evidence for prevention on self-injury behavior. Methods From June to November in 2017, 1 090 primary school students were selected by stratified cluster sampling method from Zhejiang, Guangdong, Jiangxi, Sichuan and Guizhou province in China, to analyze the association between screen time and incidence of self-injury. Results Totally 5.6% students reported screen time over 2 hours per day, boy, rural students, students with low health literacy, ever drinking had a higher rate of screen overuse(χ2=12.35, 6.94, 6.86, 16.86, P<0.05). The prevalence of screen overuse varied significantly by amount of pocket money(P<0.01). The prevalence of self-injury was 11.3%, students from western areas, boy, grade three, from rural area, adult relatives as guardians, low health literacy, smoking, drinking and screen time over 2 hours per day had a higher rate of self-injury behavior(χ2=27.31, 11.49, 23.91, 22.12, 15.11, 55.16,19.03, 25.16, 19.35, P<0.05). Compared with the students with screen time less than 2 hours per day, multiple Logistic regression analyses showed that, the OR(95%CI) values of self-injury was 2.62(1.31-5.23) among students with screen time less than 2 hours per day. Conclusion The risk of self-injury behavior is related to screen time in primary school students, specific health education should be conducted to reduce screen time.
