HIV bio-behavioural surveillance surveys conducted at regular intervals are critical for monitoring of, and informing a targeted response to the HIV pandemic. We used Respondent-driven Sampling in 2006, 2008 and 2010 to recruit men who have multiple female sexual partners. We performed several logistic regression analyses to compare HIV sexual risk behaviours, and HIV infection over time. Decreases in inconsistent condom use with main partners were not sustained in 2010. Inconsistent condom use with non-main partners, partner numbers and having one-time partners continued to decrease over time. Levels of alcohol consumption in 2010 reverted to a level higher than in 2006. Non-significant increases in HIV prevalence and reporting a symptom of a sexually transmitted infection (STI) were found. The decrease in numbers of and one-time sexual partners, and in inconsistent condom use with non-main partners augers well for decreasing HIV incidence among men in the study community, but might be offset by decreases in consistent condom use with main partners, and increases in alcohol consumption and STIs.
定期进行的 HIV 生物行为监测调查对于监测和针对 HIV 大流行做出有针对性的反应至关重要。我们于 2006 年、2008 年和 2010 年使用应答者驱动抽样法招募了有多个女性性伴侣的男性。我们进行了多次逻辑回归分析，以比较 HIV 性行为风险和 HIV 感染随时间的变化。2010 年，与主要性伴侣不坚持使用安全套的情况并未持续。与非主要性伴侣、伴侣数量和一次性伴侣使用不坚持使用安全套的情况随着时间的推移继续减少。2010 年的酒精消费水平恢复到高于 2006 年的水平。未发现 HIV 流行率和报告性传播感染（STI）症状的显著增加。性伴侣数量和一次性性伴侣的减少，以及与非主要性伴侣不坚持使用安全套的情况，预示着研究社区中男性的 HIV 发病率将会下降，但与主要性伴侣坚持使用安全套的情况减少，以及酒精消费和 STI 的增加可能会抵消这种情况。
