摘　　要：目的了解2015-2016年广西艾滋病病毒(HIV)新近感染病例的性行为特征,为制定和实施艾滋病精准防控措施提供科学依据。方法匹配新发现报告病例的既往HIV抗体检测记录,甄别出2015-2016年广西新发现报告病例中≥15岁新近感染病例,2017年1-2月,采用面对面深入访谈和问卷方式开展横断面调查,分析新近感染病例的性行为流行特征。结果共调查2015-2016年广西HIV新近感染病例219例,男性占66.7%,≥40岁占53.0%,异性性传播占71.7%,同性性传播占27.9%。在HIV抗体阴转阳期间,94.1%的新近感染病例发生过性行为,27.4%与≥2类性伴发生过性行为;24.2%为同性,5.0%为异性+同性;22.8%为配偶/异性固定性伴+异性商业/异性临时/同性性伴1~3类组合;性行为频率≥1次/月的比例,与异性固定性伴、同性性伴分别为81.5%、72.6%(χ2=32.863,P<0.01);男性病例异性性传播、同性性传播分别占57.5%、41.8%,≥40岁异性性传播占89.7%,15~39岁同性性传播占69.2%;与各类性伴发生性行为时每次使用安全套的比例均<5%。结论广西新近感染病例经性途径传播方式复杂,不安全性行为率高,存在多重交叉传染的可能,应深入推进防治艾滋病警示性教育,探索针对男男性行为者阻断家庭内传播的有效干预模式,以有效减少新发感染的发生。Objective To understand sex behavior characteristics of new HIV infections in Guangxi from 2015 to2016.Methods The newly HIV infected cases aged 15 years and above were identified through matching their HIV antibody testing records in Guangxi during 2015-2016,and face-to-face in-depth interviews and questionnaire survey were applied to collect the information and analyze the characteristics.Results 219 new HIV infections during the period were investigated,and the proportions of male,aged 40 years and above,heterosexual transmission,and homosexual transmission accounted for 66.7%,77.2%,59.0% and 29.5% respectively.During the transformation of HIV antibodies from negative to positive,94.1% of new HIV infections had sex behavior;27.4% had two and more kinds of sexual partners;24.2% had homosexual acts and 5.0% had both heterosexual and homosexual acts;22.8% had the simultaneous sexual partners such as spouse/fixed partners,commercial heterosexual/homosexual/casual heterosexual partners.Among those having sexual behavior≥1 time/month with different sexual partners,81.5% had fixed heterosexual partners,and 72.6% had homosexual partners(χ2=32.863,P<0.01).Male cases of heterosexual transmission and homosexual transmission accounted for 57.5%,and 41.8%respectively.The heterosexual transmission accounted for 89.7%in the group of 40 years old and above,and homosexual transmission for 69.2%in 15-39 years old group.The rate of condom use per sexual encounter was<5%.Conclusion The way of sexual transmission in newly infected cases is complex,and there is a high rate of unsafe sex.Multiple and cross infections exist among the new HIV infections in Guangxi.To effectively reduce HIV infection,HIV/AIDS prevention education should be further promoted,and intervention should be targeted more to MSM and those within families.
