Abstract: Objective To estimate the prevalence and associated factors of internet addiction behavior in high school students in Beijing,so as to provide theoretical basis for further intervention and prevention measures. Method A stratified cluster random sampling method was adopted,and totally 18 154 students were selected as participants in 35 key high schools,36 senior high schools and 31 vocational-technical schools in 18 districts and counties of Beijing from April to May in 2014. Results The prevalence of internet addiction was 4.7% among participants,and it was significantly higher in boys(5.5%) than that in girls (4.0%).Students with higher grade and their mothers with high level of educational background were less prone to developing internet addiction (both P<0.01).In contrast,students with poor academic achievements,studying in vocational high school and living in non-nuclear family were more susceptible to internet addiction (P<0.01).Logistic analysis showed that male,poor academic achievements,living in single-parent family,family reorganization and grandparenting,suffered from bullying,having strong feeling of loneliness and sexual behaviors experience were risk factors of internet addiction,whereas physical exercise was a protective factor(OR=0.49~0.92). Conclusions Internet addiction in adolescent is closely related to family,academic achievements,being bullied,emotional problems,physical exercise and sexual behavior experience.Therefore,family,school and society should work together on these related factors to prevent and control internet addiction in adolescents.

摘要： 目的 了解北京市高中生网络成瘾行为现状及其影响因素,为相关防控干预提供理论依据。方法 采取分层整群随机抽样方法 ,在2014年4—5月抽取北京市18个区县35所重点高中、36所普通高中和31所职业技术学校,并对18 154名学生进行了分析。结果 4.7%的学生报告有网络成瘾行为,其中男生网络成瘾报告率为5.5%,明显高于女生的4.0%(P<0.001);年级越高、母亲文化程度越高的学生网络成瘾报告率越低(χ²=41.00、23.49,P均<0.01);学习成绩自我评价低、职业高中、非核心家庭的学生更易发生网络成瘾(χ²=22.54、66.16和χ²=11.52,P均<0.01)。Logistic回归模型显示,男性、学习成绩自我评价低、单亲、重组及隔代家庭、有过受欺侮行为、常感到孤独及有过性行为是网络成瘾的危险因素,体育锻炼是网络成瘾的保护因素(OR=0.49~0.92)。结论 青少年网络成瘾与家庭、学习成绩、受欺侮行为、情绪问题、身体锻炼和性行为密切相关,应联合家庭、学校和社会对学生网络成瘾行为进行干预,并建立预防机制。
