OBJECTIVE
To describe characteristics of men having sex with men (MSM) participating in the Omega Cohort, to describe HIV-positive participants at baseline interview, and to estimate HIV incidence.
METHODS
The Omega Cohort is a study on the incidence and psychosocial determinants of HIV infection among MSM living in Montreal. MSM complete a questionnaire and are tested for HIV every six months.
RESULTS
During the previous six months, 31% and 12% of 810 participants (mean age = 33 years) reported unprotected anal sex with regular and casual partners, respectively. Eight participants (0.98%) were HIV-infected at baseline. HIV incidence was 0.89 per 100 person-years (7/787 person-years) [95% confidence interval: 0.36-1.83].
CONCLUSION
A significant proportion of participants reported current risk behaviours. Despite this, HIV incidence is relatively low. It is important to target MSM who do not practice safe sex and to encourage those practicing safe sex to sustain these behaviours.
目的
描述参与欧米伽队列研究的男男性行为者（MSM）的特征，描述基线访谈时的HIV阳性参与者，并估计HIV发病率。
方法
欧米伽队列研究是一项针对居住在蒙特利尔的男男性行为者中HIV感染发病率及社会心理决定因素的研究。男男性行为者完成一份问卷，并每六个月接受一次HIV检测。
结果
在过去六个月中，810名参与者（平均年龄 = 33岁）分别有31%和12%报告与固定和临时伴侣发生无保护肛交。八名参与者（0.98%）在基线时感染HIV。HIV发病率为每100人年0.89例（7/787人年）[95%置信区间：0.36 - 1.83]。
结论
相当一部分参与者报告了当前的危险行为。尽管如此，HIV发病率相对较低。针对未采取安全性行为的男男性行为者并鼓励采取安全性行为的人维持这些行为很重要。
