目的:了解调查地区艾滋病异性性传播的主要方式和分布特征,为艾滋病经性途径传播的控制提供依据。方法:采用横断面回顾性调查方法获取调查对象的社会人口学、异性性传播方式及性行为特征等。结果:共调查195例经异性性传播HIV感染者病例,男性140例,女性55例。其中经商业性伴传播者占60.51%;经非商业临时性伴传播者占24.62%;经固定性伴传播者占14.87%。传播方式在不同性别、年龄、文化程度、婚姻状况、职业等之间差异有统计学意义。男性以商业异性性伴传播为主(71.43%),女性以固定性伴传播为主(34.55%)。在经商业性伴和固定性伴传播者中,≥50岁年龄组所占比例较高,分别占44.07%、58.62%;经非商业临时性伴传播者以<30岁年龄组为主,占41.67%。结论:所调查地区艾滋病异性性传播方式以商业性伴传播为主,经非商业临时性伴及固定性伴传播同样需要关注。应利用多种平台采取干预措施预防艾滋病经性途径传播是该地区防控艾滋病的工作重点。
OBJECTIVE: To understand the main ways and distribution characteristics of heterosexual transmission of AIDS in the survey area, and provide the basis for the control of AIDS transmission through the sexual pathway. Methods: The cross-sectional retrospective survey method was used to obtain the social demography, heterosexual transmission and sexual characteristics of the surveyed subjects. Results: A total of 195 cases of HIV-infected persons were reported by heterosexual transmission, including 140 males and 55 females. Among them, 60.51% were commercial sex communicators, 24.62% were non-commercial sex communicators, and 14.87% were sex-linked communicators. There was significant difference in the mode of transmission between different genders, ages, educational level, marital status, occupation and so on. The prevalence of heterosexual men was mainly male (71.43%), while that of female was mainly by sexual partners (34.55%). Among commercial sexual partners and fixed sex communicators, those in the age group of ≥50 years accounted for 44.07% and 58.62% respectively, while those who were noncommercial temporary communicators aged <30 years accounted for 41.67%. Conclusion: Heterosexual transmission of AIDS in the surveyed areas is dominated by commercial sexual transmission, and non-commercial sexual intercourse and fixed sexual transmission also need attention. Prevention and control of HIV / AIDS should be the focus of interventions in the prevention and control of AIDS in the region through the use of various platforms for interventions to prevent the transmission of AIDS.
