广西防城港市2011-2018年越南籍商业女性性行为者HIV感染及高危性行为特征调查

Investigation of HIV infection and high risk sexual behavior of Vietnamese commercial female sex workers in Fangchenggang, Guangxi, 2011-2018

目的分析2011-2018年防城港市中越籍商业女性性行为者(FSW)艾滋病、性病相关行为特征及影响因素,为该市开展有效高危性行为干预措施提供科学依据。方法从艾滋病哨点监测服务器提取2011-2018年防城港市FSW哨点监测数据,按国籍分为中国籍和越南籍两组,比较两组人群人口学信息、性行为特征、艾滋病知识知晓率及血清学结果差异及艾滋病病毒(HIV)感染因素。结果 2011-2018年共调查FSW 6 343人,其中中国籍5 638人,平均年龄(28.47±7.64)岁(15~59岁);越南籍705人,平均年龄(28.84±8.57)岁(16~61岁)。不同国籍年龄构成(χ~2=6.976,P=0.008)、文化程度(χ~2=752.945,P <0.001)、场所档次(χ~2=762.582,P <0.001)及艾滋病知识知晓率(χ~2=249.697,P <0.001)等比较差异均有统计学意义。越南籍FSW最近一个月商业性行为安全套坚持使用率为74.3%,中国籍为82.5%,差异有统计学意义(P <0.001)。越南籍FSW的HIV(χ~2=75.973,P <0.001)、梅毒(TP)(χ~2=9.705,P=0.002)、丙型肝炎病毒(HCV)(χ~2=5.635,P=0.018)抗体阳性率均高于中国籍,差异均有统计学意义。多因素分析结果显示,防城港市FSW感染HIV的危险因素为越南籍[比值比(OR)=5.480,95%可信区间(CI):2.689~11.169]、最近一次商业性行为中没有使用安全套(OR=2.958, 95%CI:1.076~8.136)。结论防城港市越南籍FSW HIV、TP、HCV感染率相对较高,是该市艾滋病、性病传播的高风险人群,加强对越南籍FSW的艾滋病、性病防治知识宣传和行为干预,并提高全体FSW安全套的使用率,是今后艾滋病防治工作的重点。

Objective To analyze the behavioral characteristics and influencing factors of AIDS/STD among Chinese and Vietnamese female sex workers(FSW) in Fangchenggang city from 2011 to 2018, and to provide scientific basis for effective intervention of high-risk sexual behavior. Methods Data were collected based on HIV sentinel surveillance in the city during 2011-2018 and Chinese and Vietnamese FSW were divided by nationality. The demographic information, sexual behavior characteristics, AIDS knowledge awareness rate and serological results were compared between the two groups, followed by the analysis of the influence factors of HIV infection. Results A total of 6 343 FSW were investigated, including 5 638 Chinese, with an average age of(28.47±7.64) years between(15-59 years old), and 705 Vietnamese, with an average age of (28.84±8.57) years between(16-61 years old). The differences were statistically significant(p < 0.05) between the age of different nationalities(χ~2=6.976, P=0.008), education level(χ~2=752.945, P < 0.001), places of entertainment(χ~2=762.582, P < 0.001) and AIDS knowledge awareness rate(χ~2=249.697, P < 0.001). The rate of consistent condom use in the last month was 74.3% for the Vietnamese FSW, and 82.5% for the Chinese FSW, with the difference statistically significant(P < 0.001). The positive rates of HIV(χ~2=75.973, P <0.001), syphilis(TP)(χ~2=9.705, P=0.002), and hepatitis C virus(HCV)(χ~2=5.635, P =0.018) among the Vietnamese FSW were higher than those of the Chinese FSW, and the difference was statistically significant(P < 0.05). Multivariate analysis showed that the risk factors for HIV infection were Vietnamese(OR=5.480, 95% CI:2.689, 11.169), and no condom use in recent commercial sex(OR=2.958, 95% CI:1.076, 8.136). Conclusion The infection rate of HIV, TP and HCV of the Vietnamese FSW in Fangchenggang is relatively high. In the future we should strengthen the AIDS knowledge publicity and behavioral intervention among the Vietnamese FSW, and promote condom use for AIDS prevention and control.
