We examined whether trends in HIV testing in community-based samples of homosexual men may account for the convergence in HIV notification rates in homosexual men across the eastern states of Australia.
We examined data on self-reported HIV testing from annual cross-sectional, self-completed anonymous surveys of homosexual men conducted between 1998 and 2006 in Sydney, Melbourne and Brisbane. Men were recruited at gay community venues and events. Comparisons of HIV testing between the three cities and across time were carried out. We also compared reported rates of HIV testing across states in Private Lives, the 2005 online survey of health and wellbeing among non-heterosexual people.
Men recruited from clinics had a much higher prevalence of HIV testing and were excluded from further analyses. Among the 48 263 completed questionnaires obtained in non-clinic sites, there was a marked decline in the proportion of men who had never been tested for HIV in Sydney (from 8.1 to 5.1%, P trend < 0.001) and Brisbane (from 11.8 to 7.9%, P trend = 0.002) but no change in Melbourne. This proportion of men who had never been tested was lower in Sydney than in either Melbourne or Brisbane (P < 0.001). There were increases in the proportion of non-HIV-positive men who had been tested for HIV in the previous year across all three cities, although the proportion in Melbourne was lower than in the other two cities.
These data suggest that changes in HIV testing rates among homosexual men are insufficient to account for the recent differences in trends in HIV notifications in eastern Australia.
我们研究了以社区为基础的男同性恋样本中的艾滋病毒检测趋势是否可以解释澳大利亚东部各州男同性恋者艾滋病毒通报率的趋同现象。
我们研究了1998年至2006年在悉尼、墨尔本和布里斯班对男同性恋者进行的年度横断面、自我完成的匿名调查中自我报告的艾滋病毒检测数据。这些男性是在同性恋社区场所和活动中招募的。对三个城市之间以及不同时间的艾滋病毒检测情况进行了比较。我们还比较了2005年非异性恋者健康与幸福在线调查“私人生活”中各州报告的艾滋病毒检测率。
从诊所招募的男性艾滋病毒检测患病率要高得多，因此被排除在进一步分析之外。在非诊所场所获得的48263份完整问卷中，悉尼从未接受过艾滋病毒检测的男性比例显著下降（从8.1%降至5.1%，P趋势<0.001），布里斯班也有下降（从11.8%降至7.9%，P趋势=0.002），但墨尔本没有变化。悉尼从未接受检测的男性比例低于墨尔本和布里斯班（P<0.001）。在所有三个城市中，上一年接受过艾滋病毒检测的非艾滋病毒阳性男性比例都有所增加，尽管墨尔本的这一比例低于其他两个城市。
这些数据表明，男同性恋者中艾滋病毒检测率的变化不足以解释澳大利亚东部近期艾滋病毒通报趋势的差异。
