To review and analyse original studies on HIV prevalence and risk behaviours among men who have sex with men (MSM) in Vietnam.
Systematic literature review. Comprehensive identification of material was conducted by systematic electronic searches of selected databases. Inclusion criteria included studies conducted from 2002 onwards, following a systematic review concluding in 2001 conducted by Colby, Nghia Huu and Doussantousse. Data analysis was undertaken through the application of both the Cochrane Collaboration and ePPI Centre approaches to the synthesis of qualitative and quantitative studies.
Vietnam.
Sixteen studies, undertaken during 2005-2011, were identified that met the inclusion criteria. The analysis showed that HIV prevalence among MSM in Vietnam has increased significantly (eg, from 9.4% in 2006 to 20% in 2010 in Hanoi) and that protective behaviours, such as condom use and HIV testing and counselling, continue at inadequately low levels.
Increasing HIV prevalence and the lack of effective protective behaviours such as consistent condom use during anal sex among MSM in Vietnam indicate a potential for a more severe HIV epidemic in the future unless targeted and segmented comprehensive HIV prevention strategies for MSM in Vietnam are designed and programmes implemented.
回顾并分析越南男男性行为者（MSM）中艾滋病毒流行率及风险行为的原始研究。
系统文献综述。通过对选定数据库进行系统的电子检索，全面识别相关材料。纳入标准包括2002年以后开展的研究，遵循科尔比、义休和杜桑图塞于2001年完成的系统综述。数据分析采用Cochrane协作网和ePPI中心的方法，对定性和定量研究进行综合分析。
越南。
确定了2005 - 2011年期间开展的16项符合纳入标准的研究。分析表明，越南男男性行为者中的艾滋病毒流行率显著上升（例如，河内从2006年的9.4%升至2010年的20%），而诸如使用避孕套以及艾滋病毒检测与咨询等保护行为的水平仍然很低，不足以起到保护作用。
越南男男性行为者中艾滋病毒流行率不断上升，且缺乏有效的保护行为，如肛交时始终使用避孕套，这表明未来有可能出现更严重的艾滋病毒疫情，除非为越南男男性行为者制定有针对性的、分阶段的全面艾滋病毒预防策略并实施相关方案。
