摘要
目的了解我国网约性行为青少年性病艾滋病(sexually transimitted diseases/acquired immunodeficiency syndrome,STD/AIDS)感染情况。方法2017年9—11月,利用滚雪球法在中国部分网络社交平台对15~24岁青少年开展网约性行为现况调查,收集个人一般情况、STD/AIDS相关危险行为、自我报告STD/AIDS感染情况等信息。利用χ^(2)检验、Fisher确切概率法和决策树模型对与自我报告STD/AIDS感染相关因素进行分析。结果调查730例网约青少年,自我报告STD/AIDS感染病史31例(4.25%)。男性24例(5.97%),女性7例(2.13%),差异有统计学意义(χ^(2)=6.536,P=0.011);网约性伴为同性者16例(15.69%),异性者13例(2.27%)、双性及其他类型者2例(3.64%),差异有统计学意义(χ^(2)=27.107,P<0.01)。决策树模型共3层,8个节点,纳入3个因素;网约性伴类型、性别和年龄对因变量的标准化重要性分别为100.00%、11.60%和2.94%;Risk统计量(0.042)、索引图和收益图显示模型拟合良好;决策树模型显示,男男同性性行为人群、年龄较小、双性及其他性行为者的感染概率分别为15.69%、4.17%和2.39%,是该人群感染STD/AIDS主要影响因素。结论网约性行为青少年自我报告STD/AIDS感染率高,应针对感染相关的因素加强预防性传播疾病健康教育,实施精准干预。
Objective To understand the prevalence of sexually transmitted diseases/acquired immunodeficiency syndrome(STD/AIDS)infection and its associated factors among adolescents and young adults with online sex-seeking experience in China.Methods A cross-sectional survey of online sexual behaviors was conducted on some social media platforms in China among young people in the age range of 15-24 years selected using snowball sampling.Information about demographic characteristics,risk behaviors related to STD/AIDS,self-reported STD/AIDS infection,etc.were collected.Chi-square test,Fisher's exact test and decision tree algorithm were employed to explore the associations between the self-reported STD/AIDS infection and risk factors.Results Altogether 730 young people with on-line sex-seeking experience were surveyed,among whom 31 reported history of STD/AIDS infection(4.25%).The rate of self-reported infection in males(5.97%)was statistically significantly higher than that in females(2.13%)(χ^(2)=6.536,P=0.011);participants with homosexual partners(15.69%)had a statistically significantly higher self-reported infection rate than those with heterosexual(2.27%)or other types of partners(3.64%)(χ^(2)=27.107,P<0.01).The decision tree model consisting of 8 nodes in 3 strata identified 3 variables,namely the type of online sexual partners,gender,and age,of which the normalized importance in the decision tree were 100.00%,11.60%,and 2.94%,respectively.The risk value(0.042),index chart and gain chart demonstrated the good fitness of model.The decision tree model revealed that the predicted probabilities of infection for men who have sex with men(MSM),those of younger age,and those being bisexual or having other sexual behaviors were 15.69%,4.17%,and 2.39%,respectively,and those attributes were main factors correlated with STD/AIDS infection in this population.Conclusions Self-reported STD/AIDS infection is prevalent among adolescents and young adults with online sex-seeking experience.Health education on STD/AIDS infection should be strengthened targeting the associated factors,thereby implementing precision interventions for this population.
