摘要
目的了解经性途径传播的HIV感染者不安全性行为特征及安全套使用情况,模拟方便提供安全套对预防人免疫缺陷病毒(human immunodeficiency virus,HIV)经性途径传播的效果。方法采用问卷调查法,对新报告的经性途径感染的HIV阳性者感染告知前6个月内的相关情况进行调查,通过数学模型估计提供方便安全套对预防HIV经性途径传播的预期效果。结果感染告知前6个月内调查对象安全套使用率为36.4%,其中63.6%的调查对象从未使用过安全套,14.8%有时使用,9.6%经常使用,12.0%坚持每次使用;未坚持使用安全套的原因受一种或多种因素影响,未坚持使用安全套的研究对象中,30.9%在发生不安全性行为时未及时获得安全套;方便提供安全套预期可避免13.79%的不安全性行为发生,减少10.92%经性途径传播造成的HIV新发感染。结论公共娱乐场所等地提供方便可取的安全套可一定程度降低不安全性行为发生,对阻止HIV经性途经传播具有一定效果。
Objective To analyze the unprotected sexual behavior and condom use rate among sexually transmitted HIV-positive patients,imitating the effectiveness of improving condom access on preventing HIV transmission through sexual behaviors. Methods A survey was conducted among sexually transmitted HIV-positive patients using questionnaires to collect general information during the last 6 months before notification of HIV infection. Effectiveness of improving condom access on preventing HIV transmission was estimated by mathematical models. Results Among total subjects, the condom use rate was only 36. 4%. During the last 6 months before notification of HIV infection, 63.6% never used condoms, 14. 8% sometimes used, 9. 6% often used, and only 12. 0% insisted on using condoms. The reasons why subjects did not insist on using condoms were different, with 30.9% didn＇ t obtain condoms timely when they had unprotected sexual behaviors. As expected, the occurrence of unprotected sexual behaviors and new cases of HIV infections were decreased by 13.79% and 10. 92%, respectively, by improving the condom access. Conclusions Providing access to condoms in public places would reduce HIV transmission.
