【摘要】 目的了解人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染者/获得性免疫缺陷综合征(acquired immunodeficiency syndrome,AIDS)患者经非婚异性性接触感染的高危性行为特点及其影响因素,为控制艾滋病经性传播策略制定提供科学数据。方法连续抽取云南省2015年新报告非婚异性传播HIV/AIDS病例,进行问卷调查,了解调查对象获知感染HIV前后危险行为等情况。结果调查男性498人、女性490人。获知感染HIV前一年内有商业性行为的比例为39.88%(男性占68.67%,女性占10.61%),性别差异有统计学意义(x~2=352.797,P<0.001),地点集中在路边店/街头,坚持使用安全套比例仅为8.38%;71.36%有临时性伴间性行为(男性占64.46%,女性占78.37%),且性别差异有统计学意义(x~2=23.379,P<0.001),临时性伴主要是朋友/熟人(占82.52%);存在多种性行为交叉和叠加。获知感染HIV后仍有12.96%发生高危性行为,仅31.86%愿意告知性伴自身的感染状况。结论异性传播影响人群扩大,控制异性传播的策略应转为在强化高危人群干预工作基础上,倡导全民推广使用安全套的普遍防护,宣传教育时增加风险行为识别和安全性行为警示性教育,艾滋病感染者随访管理工作中应评估其传播风险并采取相应措施。更多还原

【Abstract】 Objective To explore the high-risk sexual behavior features and its influencing factors of the human immunodeficiency virus( HIV)/acquired immunodeficiency syndrome( AIDS) cases with extra-marital heterosexual transmission,and to provide basic data for controlling HIV heterosexual transmission. Methods New reported HIV/AIDS cases with extra-marital heterosexual transmission in Yunnan Province in 2015 were recruited. Face to face questionnaire was used to get the information as risk behaviors before and after inform HIV infection. Results A total of 498 males and 490 females were recruited; 39. 88%( male 68. 67%,female 10. 61%) of the cases had business sexual behaviors before informing HIV infection in the near one year,there was significant difference between genders( x~2= 352. 797,P < 0. 001).The site centralized in the street sides. Persistent condom using rate was only 8. 38%; 71. 36%( male 64. 46%,female78. 37%) had temporary sexual behavior,there was significant difference between genders( x~2= 23. 379,P < 0. 001).82. 52% were among the friends/acquaintances. The multiple and cross sexual behavior existed. 12. 96% of those informed infected cases still insisted unprotected high risk sexual behaviors. Only 31. 86% of them were willing to tell the sexual partners their infection status. Conclusions Heterosexual HIV/AIDS transmission population is enlarging. The strategy should transfer into strengthen high-risk population intervention,and advocate universal condom use. Sexual responsibilities,sexual health and sexual safety propaganda should be added as well. The spread risk assessment of the HIV/AIDs in the follow-up management should be included and steps should be taken accordingly.更多还原
