目的评价广东省女性性工作者(FSW)中梅毒防控工作效果,为后期工作调整干预措施及策略提供理论依据。方法对2009年1月—2013年12月广东省皮肤性病防治系统性病艾滋病高危人群干预工作中的FSW的梅毒感染检测结果进行分析。结果 2009—2013年广东省共检测FSW34 338人次,其中高档FSW23 816人次(69.36%),中档8 811人次(25.66%),低档1 711人次(4.98%)。2009年高、中、低档FSW的梅毒感染率分别为2.60%、7.36%、10.54%,2013年分别为1.45%、2.75%、21.88%;χ2趋势检验结果显示,2009—2013年期间,高档及中档FSW中的梅毒感染率均呈下降趋势(χ2值分别为12.807、52.333,均P<0.001),而低档FSW中的梅毒感染率则一直保持在较高状态(χ2=0.027,P=0.87)。2013年不同档次FSW之间的梅毒感染率差异存在统计学意义(χ2=190.64,P<0.001);珠三角、粤东、粤西及粤北3个片区之间的FSW梅毒感染率差异无统计学意义(χ2=5.24,P=0.07)。结论不同档次的FSW之间梅毒感染率存在较大差异;低档FSW中存在较高的梅毒感染率,且梅毒检测覆盖人数较少。
Objective To evaluate the effect of syphilis prevention and control in female sex workers (FSW) in Guangdong Province, and to provide theoretical basis for adjusting intervention measures and strategies in later work. Methods The detection results of syphilis infection in FSW during the intervention of high risk population of STD / AIDS in dermatology prevention and control system of Guangdong Province from January 2009 to December 2013 were analyzed. Results In 2009-2013, FSW34 was detected in 338 338 people in Guangdong Province, among which 8,161 were high-end FSW23 (69.36%), 8,811 mid-range (25.66%) and low-grade 1 711 (4.98%). In 2009, syphilis infection rates of high, medium and low-grade FSW were 2.60%, 7.36% and 10.54% respectively, 1.45%, 2.75% and 21.88% respectively in 2013 and χ2 trend test results. In 2009-2013, The infection rate of syphilis in mid-range FSW showed a decreasing trend (χ2 = 12.807, 52.333, respectively, P <0.001), while the prevalence of syphilis in low-grade FSW remained high (χ2 = 0.027, . There were significant differences in the syphilis infection rates among different grades of FSW in 2013 (χ2 = 190.64, P <0.001). There was no statistical difference in the prevalence of syphilis infection among the three sub-areas in PRD, eastern Guangdong, western Guangdong and northern Guangdong Significance (χ2 = 5.24, P = 0.07). Conclusion There is a big difference in the prevalence of syphilis infection among different grades of FSWs. There is a high prevalence of syphilis infection in low-grade FSWs with a small number of syphilis detection coverage.
