HIV-infected Female Sex Workers High Risk Behavior and Attitude Changes in Kaiyuan City,Yunnan Province,China

Objective To investigate the attitude and sexual behavior status and change among HIV positive female workers in entertainment sites in Kaiyuan city, Yunnan province, China. The key information should be applied in the integrated intervention program in future.
Methods A cohort survey among HIV positive female workers was conducted during 12 months, between 2010 and 2012. All the risk sexual behavior and attitude were collected for assessment for the potential secondary transmission to sexual partners.
Results Of 99 HIV positive women who sell sex in Kaiyuan city, 99 participated in the survey at baseline, 80, 80, 75, and 75 at 3-, 6-, 9-, and 12-month follow-ups. The percentage of participants who reported consistently used condoms in the last one month ranged between 94.5% and 95.5%. The client volume in the last one month, income per sex and age group were significant related with non-insistent condom use with their clients.
Conclusion It was suggested that integrated intervention program package should include 100 percent condom use promotion for the HIV positive FSW with all sexual partners, and also, include socially support involved.     

暗娼人群艾滋病队列研究中失访对HIV新发感染估计的影响

目的 分析在云南省开远市暗娼(female sex worker,FSW)队列中的失访率、HIV新发感染率及其影响因素,探讨失访对HIV新发感染率估计的影响。方法 云南省开远市FSW人群开放式队列研究,始于2006年3月,每6个月进行1次调查,截止2013年6月,共进行了7年的随访调查。本研究选取2006年3月基线调查的661名HIV阴性FSW人群,分析其7年随访调查的失访率,采用Cox回归模型探讨HIV新发感染的危险因素及影响失访的因素。同时于2013年6月通过联系本人或知情人士对失访的FSW人群进行失访原因调查,分析失访对HIV新发感染估计的影响。结果 661例HIV阴性FSW人群共随访1 238.5人年,HIV新发感染率为1.29(95%CI:0.74～2.10)/100人年,失访的发生率为48.68(95%CI:44.88～52.73)/100人年。Cox多因素分析显示,对于HIV新发感染,吸毒是FSW感染HIV的独立危险因素(aRR=4.15,95%CI:1.43～12.02);对于失访,年龄>25岁(aRR=0.68,95%CI:0.57～0.81)、吸毒(aRR=0.52,95%CI:0.35～0.79)的FSW有着较低的失访率,更易保持在队列中。结论 开远市FSW队列在长期随访中存在较高的失访率,而失访人群发生HIV感染的风险低于HIV随访的人群,可能高估了该市FSW的新发感染率,今后有必要进一步研究FSW人群失访的原因,同时研究提高FSW人群队列随访保持率的策略。
