| 目的 了解天津市跨性别女性（TGW）人群规模，分析该人群性行为特征，为制定防控措施提供依据。方法 采用捕获-再捕获方法，估计天津市TGW人群规模，同时收集匿名调查问卷，对TGW人群的性行为进行多因素logistic分析。采用问卷星建立调查问卷数据库，采用SPSS 24.0软件进行统计学分析。结果 共调查TGW人群213人，估计天津市TGW人群规模为599（95%CI：407~792）人。TGW人群坚持使用安全套的多因素logistic回归分析结果显示，最近3个月有固定性伴的人坚持使用安全套的比例较低（与最近3个月无固定性伴者相比，aOR=0.44，95%CI：0.23~0.82），最近1年做过HIV抗体检测者坚持使用安全套的比例较高（与最近1年与未做过HIV抗体检测者相比，aOR=2.73，95%CI：1.06~6.99）。结论 需要加强TGW人群及其固定性伴的HIV动员检测，提高安全套的使用率。 |

| Objective To investigate the population size of transgender women (TGW) in Tianjin and analyze the characteristics of their sexual behaviors to provide a basis for AIDS prevention and control. Methods To estimate the population size of TGW in Tianjin using the capture-recapture method. At the same time, an anonymous questionnaire was collected to conduct a multi-factor logistic analysis of the TGW population's sexual behavior. Results A total of 213 TGW were investigated. Tianjin's estimated TGW population size was 599 (95%CI: 407-792). Multivariate logistic analysis of the use of condoms consistently showed that compared with TGW without regular sex partners, those with regular sex partners had a lower proportion of consistent condom use (aOR=0.44, 95%CI: 0.23-0.82) and had received HIV tests in the last year were more likely to adhere to condom use than those who had not been tested (aOR=2.73, 95%CI: 1.06-6.99).Conclusion It is necessary to strengthen HIV mobilization testing among the TGW population and their regular sexual partners to improve condom use. |
