| 目的 了解北京市男男性行为者(MSM)HIV血清抗体阳转率的动态变化情况及影响因素.方法 2009年8-12月在北京市招募962名MSM,其中809名HIV阴性进入队列,每6个月随访检测HIV抗体,并进行体检和行为学问卷调查.结果 在招募的962名MSM中,HIV感染率为6.34％(61/962).对809名HIV阴性者在第6、12和18个月随访时,队列保持率分别为95.1％(769/809)、85.5％( 692/809)、71.0％ (574/809)；HIV血清抗体阳转者分别为19、29和17例；HIV新发感染率分别为5.47/100人年、12.37/100人年、6.86/100人年.18个月随访期间的HIV新发感染率为7.59/100人年.多因素Cox回归模型分析显示,年龄≤25岁(HR=2.32,95％CI:1.39 ～3.87)、认识圈内的朋友数＞8个(HR=2.50,95％CI:1.49～4.20)、月经济收入＜2000元(HR=1.76,95％CI:1.06～2.95)、最近6个月男男性行为人数＞4人(HR=3.50,95％CI:2.11 ～5.81)、体检包皮为包茎或包皮过长或较长者(HR=2.47,95％CI:1.50～4.07)和梅毒检测结果阳性(HR=2.62,95％CI:1.53～4.49)同HIV新发感染的差异有统计学意义.结论 北京市MSM中HIV新发感染率较高,提示该人群中HIV在快速传播. |

| Objective To investigate the dynamic change and associated risk factors of HIV sero-conversion rate in Beijing.Methods 809 sero-negative men who have sex with men (MSM) were recruited in the cohort from August to December in 2009.HIV sero-antibody,medicinal examination and behavior questionnaire interview were carried out every six months.Results 962 MSM with overall baseline prevalence of HIV infection as 6.34％ (61/962) together with 809 seronegative MSM,were enrolled in the cohort.Of the 809 sero-negative participants,95.1％ (769/809),85.5％ ( 692/809 ) and 71.0％ ( 574/809 ) of them were retained in the 6-month,12-month and 18- month follow-up visits,with 19,29 and 17 of them became HIV sero-conversion at 6-month,12-month,and 18-month follow-up visits and the HIV incidence rates appeared to be 5.47,12.37 and 6.86 per 100 person-years respectively.The HIV incidence was 7.59 per 100 person-years in the 18 months follow-up visit.Factors including:younger than 25-years old (HR =2.32,95％CI:1.39-3.87),having more than 8 MSM partners (HR=2.50,95％CI:1.49-4.20),less than RMB 2000 Yuan every month income (HR=1.76,95％CI:1.06-2.95 ),having more than 4 homosexual partners in the last six months (HR=3.50,95％ CI:2.11 -5.81 ),showing phimosis and redundant prepuce (HR=2.47,95％ CI:1.50-4.07 ) as well as positive syphilis test (HR=2.62,95％CI:1.53-4.49) etc.,were significantly associated with HIV incidence.Conclusion High HIV incidence was shown among MSM in Beijing and had spread fast in this population,calling for more favorable prevention measures to be taken. |
