目的了解江门市低档女性性服务人群(FSW)艾滋病相关知识、安全套使用情况及其影响因素,为控制艾滋病的蔓延提供科学依据。方法利用2010-2013年国家级暗娼监测哨点的数据资料进行分析。结果调查的1272名FSW中,艾滋病相关知识知晓率为72.25%(919人);最近一个月与客人发生性行为时每次都使用安全套的比例为55.42%。经多因素Logistic回归分析结果显示,最近一年曾患过性病[比值比(OR)=0.717,95%可信区间(CI):0.509~0.940]、接受过干预服务(OR=0.0668,95%CI:0.473~0.944)、艾滋病检测服务(OR=0.608,95%CI:0.417~0.887)及同伴教育(OR=0.612,95%CI:0.404~0.928)是安全套使用的促进因素,而文化程度低(OR=1.362,95%CI:1.109~1.594)、艾滋病相关知识知晓率低(OR=2.076,95%CI:1.559~1.765)是安全套使用的阻碍因素。结论江门市低档FSW的安全套使用比例逐年增加,但坚持每次使用安全套的比例仍较低,提高该人群艾滋病相关知识知晓率可促进安全套的使用。
Objective To understand the HIV / AIDS-related knowledge and the use of condoms in low-grade female sexual service workers (FSWs) in Jiangmen and its influencing factors so as to provide a scientific basis for controlling the spread of AIDS. Methods The data of sentinel surveillance of national sex workers from 2010 to 2013 were analyzed. Results Among 1,272 FSWs surveyed, the awareness rate of HIV / AIDS related knowledge was 72.25% (919). Condom use was 55.42% when they had sex with their clients during the recent month. The multivariate Logistic regression analysis showed that the most recent year had sexually transmitted disease (odds ratio (OR) = 0.717, 95% confidence interval (CI): 0.509 to 0.940] and received intervention services (OR = 0.0668, 95% (OR = 0.608, 95% CI: 0.417-0.887) and peer education (OR = 0.612, 95% CI: 0.404-0.928) were the contributing factors for condom use, while those with low education level (OR = 1.362, 95% CI: 1.109-1.594). The awareness rate of AIDS-related knowledge was low (OR = 2.076, 95% CI: 1.559-1.765) as an obstacle to condom use. Conclusions The proportion of low-grade FSW condoms in Jiangmen City has been increasing year by year. However, the proportion of condom users who use condoms at each time is still relatively low. Improving awareness of AIDS-related knowledge in this population can promote the use of condoms.
