目的了解柳州市2007～2008年度男男性接触者(MSM)的艾滋病病毒(HIV)、丙型肝炎病毒(HCV)、梅毒螺旋体(TP)感染情况。方法2007年4～7月、2008年4～7月及10～12月,连续三轮累计对柳州市区790名男男性行为者进行调查,采血检测抗-HIV、抗-HCV、梅毒抗体。结果双性恋MSM的HIV、HCV、TP感染率均高于同性恋,差异无统计学意义(P>0.05),40岁及以上年龄组的MSM人群HIV、梅毒感染率均大大高于40岁以下各组,不同年龄组间的差异均无统计学意义(P>0.05),最近6个月男性性伴数在增加的同时,HIV阳性人数及TP阳性人数也在相应增加,而选择记不清及拒答者的情况更是严重,普遍高于其他组。结论本地区男男性接触者因多性伴、异性性行为、经济原因等因素,导致HIV、HCV、TP感染率较高,应进一步加大在MSM人群中的艾滋病、性病防治知识的健康宣传教育和行为干预,才能进一步遏制其传播。
