National HIV serological and behavioural surveillance of Bangladesh repeatedly demonstrated a very high proportion of rickshaw pullers in Dhaka city, having sex with female sex workers (FSWs) and using illicit substances. However, no study has been conducted to identify the correlates of having sex with FSWs among this population. This study aimed to describe behavioural profile of rickshaw pullers in Dhaka city using probability samples and to identify the correlates for having sex with FSWs in order to focus HIV prevention intervention.
Six hundred rickshaw pullers were randomly selected from rickshaw garages in the Kamrangirchar area, the single largest slum cluster of Dhaka, Bangladesh, during March-April 2008 using the Proportion Probability to Size method. Participants were interviewed, with a response rate of 99.2% (n = 595), using a structured questionnaire and asked about illicit substance use, sexual behaviour and risk perception for HIV and sexually transmitted diseases. Independent predictors of having sex with FSWs were analysed by multivariate analysis. A qualitative study was subsequently conducted with 30 rickshaw pullers to supplement the findings of the initial survey.
The proportion of survey respondents who had sex with FSWs and those who used illicit substances in the previous 12 months period were 7.9% and 24.9%, respectively, much lower than the results achieved in the 2003-04 behavioural surveillance (72.8% and 89.9%, respectively). Multivariate analysis revealed the characteristics of younger age, being never married, living alone with family remaining in other districts and using illicit substances in the previous 12 months were significantly associated with having sex with FSWs.
HIV-related risk behaviour of our study population of the rickshaw pullers was lower than what has been suggested by the results of behavioural surveillance. While this discrepancy should be addressed in further studies, our study emphasizes the importance of focused HIV prevention programs for rickshaw pullers as high-risk behaviour is displayed at an unacceptable level and concentrated in identifiable sub-populations.
孟加拉国的全国艾滋病毒血清学和行为监测反复表明,达卡市人力车夫与女性性工作者发生性行为并使用非法药物的比例非常高。然而,尚未开展任何研究来确定该人群中与女性性工作者发生性行为的相关因素。本研究旨在通过概率抽样描述达卡市人力车夫的行为特征,并确定与女性性工作者发生性行为的相关因素,以便集中开展艾滋病毒预防干预措施。
2008年3月至4月期间,采用按规模比例概率抽样方法,从孟加拉国达卡最大的单一贫民窟集群卡姆兰吉尔查尔地区的人力车车库中随机抽取600名人力车夫。使用结构化问卷对参与者进行访谈,回复率为99.2%(n = 595),询问他们非法药物使用情况、性行为以及对艾滋病毒和性传播疾病的风险认知。通过多变量分析确定与女性性工作者发生性行为的独立预测因素。随后对30名人力车夫进行了定性研究,以补充初步调查的结果。
在过去12个月内与女性性工作者发生性行为的受访者比例和使用非法药物的受访者比例分别为7.9%和24.9%,远低于2003 - 2004年行为监测的结果(分别为72.8%和89.9%)。多变量分析显示,年龄较小、从未结婚、独自居住且家人留在其他地区以及在过去12个月内使用非法药物这些特征与与女性性工作者发生性行为显著相关。
我们研究的人力车夫群体中与艾滋病毒相关的风险行为低于行为监测结果所显示的水平。虽然这种差异应在进一步研究中加以探讨,但我们的研究强调了针对人力车夫开展重点艾滋病毒预防项目的重要性,因为高风险行为处于不可接受的水平且集中在可识别的亚人群中。
