In 2006 we conducted a cross-sectional study involving hospital clinical centres in five Italian cities to compare the sexual behaviour of HIV-positive MSM (men who have sex with men) before and after the diagnosis of HIV infection. Each centre was asked to enrol 30 HIV-positive persons aged ≥ 18 years. The questionnaire was administered to 143 MSM on average 9 years after HIV diagnosis. After diagnosis there was a decrease in the number of sexual partners: the percentage of persons who reported having had more than 2 partners decreased from 95.8% before diagnosis to 76.2% after diagnosis. After diagnosis, there was a significant decrease in the percentage of persons who had never (or not always) used a condom with their stable partner for anal sex from 69.2% before diagnosis to 26.6% after diagnosis and for oral-genital sex from 74.8% before diagnosis to 51.7% after diagnosis. Though at-risk behaviour seems to decrease after diagnosis, seropositive MSM continue to engage in at-risk practices: one fourth of them did not use a condom during sexually transmitted infections (STI) episodes, 12.5% of the participants had had sex for money, and 8.4% had paid for sex. The study shows that our sample of Italian HIV-positive MSM, though aware of being infected, engage in sexual behaviours that could sustain transmission of HIV and other STIs. The results could constitute the first step in implementing national prevention programs for persons living with HIV.
2006 年，我们进行了一项横断面研究，涉及意大利五个城市的医院临床中心，旨在比较 HIV 阳性男男性行为者（MSM）在 HIV 感染诊断前后的性行为。每个中心被要求招募 30 名年龄≥18 岁的 HIV 阳性者。平均在 HIV 诊断后 9 年，对 143 名 MSM 进行了问卷调查。诊断后，性伴侣数量减少：报告有超过 2 个性伴侣的人数百分比从诊断前的 95.8%下降到诊断后的 76.2%。诊断后，与稳定伴侣进行肛交时从不（或不总是）使用安全套的人数百分比从诊断前的 69.2%显著下降到诊断后的 26.6%，与口腔-生殖器性交从不（或不总是）使用安全套的人数百分比从诊断前的 74.8%下降到诊断后的 51.7%。尽管高危行为似乎在诊断后减少，但血清阳性 MSM 仍继续从事高危行为：四分之一的人在性传播感染（STI）发作期间不使用安全套，12.5%的参与者为了金钱发生性行为，8.4%的人支付过性行为费用。该研究表明，我们的意大利 HIV 阳性 MSM 样本虽然意识到自己被感染，但仍从事可能导致 HIV 和其他 STI 传播的性行为。研究结果可能是为艾滋病毒感染者实施国家预防计划的第一步。
