目的了解西昌市暗娼无保护商业性行为的发生情况及其影响因素。方法从社区中招募暗娼并进行一对一问卷调查,调查其社会人口学、行为学及安全套使用情况。数据采用SAS 9.2做统计学处理,采用χ2检验进行单因素分析,运用logistic回归分析确定影响无保护商业性行为的因素。结果在被调查的404名暗娼中,近1个月与嫖客发生过无保护性行为的比例为9.41%(38/404),多因素logistic回归分析结果显示,年收入(OR=2.2,95%CI=1.1~4.7)、首次性行为年龄(OR=2.6,95%CI=1.2~5.9)是暗娼发生无保护商业性行为的影响因素。结论西昌市社区暗娼发生无保护商业性行为的比例较高,应针对其影响因素采取更有效的干预措施以控制性传播疾病经此桥梁人群传播。
Objective To understand the occurrence and influencing factors of unprotected commercial sex among female sex workers in Xichang City. Methods Female sex workers were recruited from the community and one-on-one questionnaires were conducted to investigate their social demography, behavior and condom use. The data were statistically analyzed using SAS 9.2. Univariate analysis using χ2 test and logistic regression analysis were used to determine the factors influencing unprotected commercial sex. Results Among the 404 investigated sex workers, 9.41% (38/404) had unprotected sex with their clients in the past month. Multivariate logistic regression analysis showed that the annual income (OR = 2.2, 95% CI = 1.1 ~ 4.7). The first sexual behavior age (OR = 2.6, 95% CI = 1.2 ~ 5.9) was the influencing factor of unprotected commercial sex workers. Conclusion There is a high proportion of commercial sex workers engaged in unprotected commercial sex in Xichang City. More effective interventions should be taken to control the transmission of sexually transmitted diseases through this bridge population.
