Abstract

UNLABELLED

Background In this paper, factors associated with HIV and syphilis infection in three cities in Papua New Guinea are explored.

METHODS

Respondent-driven sampling surveys among FSW in Port Moresby, Lae, and Mt. Hagen (2016-17) were conducted. FSW who were aged ≥12 years, who were born female, who spoke English or Tok Pisin and who had sold or exchanged vaginal sex in the past 6 months were eligible to participate. Participants were interviewed face-to-face and offered rapid HIV and syphilis testing. Survey logistic procedures were used to identify factors associated with HIV and syphilis infection, including modern contraception use, physical violence and having a casual male partner. Weighted data analysis was conducted.

RESULTS

Overall, 2901 FSW (Port Moresby, 673; Lae, 709; and Mt. Hagen, 709) were enrolled in the study. HIV prevalence was 15.2% in Port Moresby, 11.9% in Lae and 19.6% in Mt. Hagen. Factors associated with HIV varied by city; for example, use of modern contraception in Port Moresby, experiences of physical violence in Lae and ever having tested for HIV in Mt. Hagen. No one variable was associated with HIV in all cities. Prevalence of syphilis infection was 7.1%, 7.0%, and 3.0% in Port Moresby, Lae, and Mt. Hagen, respectively. Factors associated with syphilis infection also varied by city and were only significant in Lae.

CONCLUSION

The different factors associated with HIV and syphilis infection in each city highlight the complex HIV and syphilis epidemics among FSW and the importance of conducting surveys in multiple locations and developing local interventions.

摘要

背景

本文探讨了巴布亚新几内亚三个城市中与 HIV 和梅毒感染相关的因素。

方法

在 2016-17 年期间，对莫尔斯比港、莱城和芒特哈根的性工作者（FSW）进行了基于应答者驱动抽样的调查。符合以下条件的 FSW 可参与研究：年龄≥12 岁、女性、会说英语或托克劳皮钦语、在过去 6 个月内有过阴道性交的商业性行为。参与者接受了面对面访谈，并提供了 HIV 和梅毒快速检测。使用调查逻辑程序来确定与 HIV 和梅毒感染相关的因素，包括现代避孕方法的使用、身体暴力和偶然的男性伴侣。进行了加权数据分析。

结果

共有 2901 名 FSW（莫尔斯比港 673 名、莱城 709 名和芒特哈根 709 名）参与了研究。莫尔斯比港的 HIV 感染率为 15.2%，莱城为 11.9%，芒特哈根为 19.6%。与 HIV 相关的因素因城市而异；例如，莫尔斯比港的现代避孕方法使用、莱城的身体暴力经历以及芒特哈根的 HIV 检测史。没有一个变量与所有城市的 HIV 都相关。莫尔斯比港、莱城和芒特哈根的梅毒感染率分别为 7.1%、7.0%和 3.0%。与梅毒感染相关的因素也因城市而异，仅在莱城有统计学意义。
