目的了解昆明市HIV阳性的MSM人群动员其性伴接受HIV检测情况及感染影响因素,提高MSM人群阳性发现率。方法将研究期间以方便抽样纳入的HIV阳性MSM者作为种子进行性伴HIV检测动员招募,动员阳性MSM种子近一年内的同性性伴接受HIV抗体检测,收集接受检测的性伴种子的人口学特征、性伴自身的人口学特征和性行为情况,对性伴HIV感染影响因素分析采用单、多因素Logistic回归分析。结果此研究纳入的阳性MSM种子71例,种子成功动员的比例为69.0%(49/71)。成功动员同性性伴53名接受HIV抗体检测,阳性检出率为18.9%(10/53)。多因素Logistic回归结果显示:性伴既往做过HIV检测[5.7%(2/35);OR(95%CI):0.105(0.017~0.646)],性伴近6个月坚持使用安全套[3.4%(1/29);OR(95%CI):0.083(0.009~0.795)]HIV感染风险较低。结论在MSM人群中,相较VCT检测方式HIV阳性者的性伴动员方式的性伴阳性发现效率较高,性伴既往没有做过HIV检测,近6个月没有坚持使用安全套可能是性伴感染HIV的危险因素。建议在MSM人群的社区文化建设中加强性伴检测宣传教育工作,指导更多的MSM感染者动员性伴接受HIV检测。
Objective To understand the HIV-positive MSM population in Kunming to mobilize their sexual partners to receive HIV testing and influencing factors, and to improve the positive rate of MSM population. Methods During the study, HIV-positive MSMs, which were easily sampled during the study, were recruited as seeds for sexual testing with HIV. Mobilized positive MSM seeds were tested for HIV antibody by homosexual partners within the past year. The demographic characteristics of the tested sexual partners were collected , Their own demographic characteristics and sexual behavior of sexual partners, sexual partners with HIV infection factors analysis using single and multivariate logistic regression analysis. Results In the study, 71 positive MSM seeds were included in this study, and the percentage of successful seed mobilization was 69.0% (49/71). Fifty-three HIV-positive patients were successfully mobilized for same-sex sexual partners, with a positive rate of 18.9% (10/53). Multivariate logistic regression analysis showed that sexual partners had previously performed HIV testing [5.7% (2/35); OR (95% CI: 0.105 (0.017-0.664) (1/29); OR (95% CI): 0.083 (0.009-0.795)] The risk of HIV infection is low. Conclusions In the MSM population, the detection rate of sexual partners was higher than that of HIV-positive sexual partners in HIV-positive VCT patients. Sex partners had not done any HIV tests before in the past 6 months. Condom use in the past 6 months was not likely to be associated with sexual partners HIV risk factors. It is suggested to strengthen sexual partner detection, publicity and education in the community culture construction of MSM population and guide more MSM patients to mobilize sexual partners to undergo HIV testing.
