需要对拥有多名女性性伴侣的高危异性恋男性进行定期的艾滋病毒生物行为监测调查，以监测艾滋病毒流行情况和危险行为趋势。在2006年和2008年，我们使用受访者驱动的抽样来招募HRH男性，并检查两个时间点之间艾滋病毒流行率和风险行为的差异。在两次调查中，目标人群在从他们的社会网络中招募能够维持连锁转诊过程的其他人方面几乎没有困难。关键变量在一到六次招募浪潮和同质性中达到平衡在2006年至2008年期间，主要性伴侣的安全套使用情况、性伴侣数量和酒精消费量存在显著差异，在推断出更可靠的趋势之前，需要对这一人群进行进一步的BBSS调查
Regular HIV bio-behavioural surveillance surveys (BBSS) among high risk heterosexual (HRH) men who have multiple female sexual partners is needed to monitor HIV prevalence and risk behaviour trends, and to improve the provision and assessment of HIV prevention strategies for this population In 2006 and 2008 we used respondent-driven sampling to recruit HRH men and examine differences in HIV prevalence and risk behaviours between the two time points In both surveys the target population had little difficulty in recruiting others from their social networks that were able to sustain the chain-referral process Key variables reached equilibrium within one to six recruitment waves and homophily indices showed neither tendencies to in-group nor out-group preferences Between 2006 and 2008 there were significant differences in condom use with main sexual partners, numbers of sexual partners, and alcohol consumption Further BBSS among this population are needed before more reliable trends can be inferred
