Female sex workers (FSWs) are a key-affected population susceptible to acquiring HIV and sexually transmitted infections (STIs), as well as transmitting the virus to others. The aim of the study was to assess HIV and syphilis prevalence among FSWs in Nepal and to examine factors associated with it.
The study was based on Integrated Biological and Behavioral Surveillance (IBBS) surveys among FSWs in Nepal from 2004 to 2015. Statistical analysis used chi-squared test to assess statistically significant risk factors for HIV and syphilis. Logistic regression models were used to identify the most important determinants for each outcome.
A total of 5,958 FSWs were tested, and among them, 100 (1.7%) were HIV positive and 230 (3.9%) were syphilis positive. The multivariate analysis revealed that syphilis was higher among those street-based, aged ≥35 years, illiterate, and with a duration of sex work of >3 years. HIV was higher among those aged ≥35 years, illiterate, street-based, and with a duration of sex work >3 years. Syphilis was strongly correlated with HIV.
HIV epidemic among FSWs in Nepal appears in the stagnant trend, whereas STI epidemic has increased in recent years. The high influencing factors for HIV and syphilis prevalence were advanced age, street-based, lower education, and longer duration of sex work. Urgent efforts, as part of routine HIV/STI prevention and intervention, are required to reduce the high burden of syphilis among FSWs.
女性性工作者是易感染艾滋病毒和性传播感染并将病毒传播给他人的重点受影响人群。本研究的目的是评估尼泊尔女性性工作者中艾滋病毒和梅毒的流行情况,并研究与之相关的因素。
该研究基于2004年至2015年对尼泊尔女性性工作者进行的综合生物和行为监测(IBBS)调查。统计分析采用卡方检验来评估艾滋病毒和梅毒的统计学显著风险因素。使用逻辑回归模型来确定每个结果的最重要决定因素。
共对5958名女性性工作者进行了检测,其中100人(1.7%)艾滋病毒呈阳性,230人(3.9%)梅毒呈阳性。多变量分析显示,在街头从业、年龄≥35岁、文盲且性工作时长>3年的女性性工作者中,梅毒感染率更高。在年龄≥35岁、文盲、街头从业且性工作时长>3年的女性性工作者中,艾滋病毒感染率更高。梅毒与艾滋病毒密切相关。
尼泊尔女性性工作者中的艾滋病毒疫情呈停滞趋势,而近年来性传播感染疫情有所增加。艾滋病毒和梅毒流行的高影响因素是年龄较大、街头从业、教育程度较低以及性工作时长较长。作为常规艾滋病毒/性传播感染预防和干预的一部分,需要紧急努力以减轻女性性工作者中梅毒的高负担。
