The Australian HIV and sexually transmissible infection (STI) behavioural surveillance system (the repeated cross-sectional Gay Community Periodic Surveys, GCPS) has been conducted since 1998 and covers six main Australian jurisdictions. In this paper, we review its history and methodology, and the available indicators, their trends and their use.
We describe the design and history of GCPS. For analyses of indicators, we use Pearson's χ²-test and test for trend where appropriate.
About 90% of gay men in Australia have been tested for HIV (60% to 70% of men who were not HIV-positive) have been tested as recommended in the preceding 12 months. STI testing levels (≈ 70% in the preceding 12 months) are high, but remain insufficient for STI prevention. In general, unprotected anal intercourse with regular (UAIR) and casual (UAIC) sex partners has increased over time. The prevalence and increasing trends in UAIR were similar across jurisdictions (P-trend <0.01), while trends in UAIC differed across the states: during 2001-08, UAIC declined in NSW (P-trend <0.01) and increased elsewhere (P-trend <0.01). Trends in UAIC were associated with HIV diagnoses.
This review of the design, implementation and findings of the Australian HIV/STI behavioural surveillance highlights important lessons for HIV/STI behavioural surveillance among homosexual men, particularly the need for consistent data collection over time and across jurisdictions. Investment in systematic behavioural surveillance appears to result in a better understanding of the HIV epidemic, the availability of a warning system and a better targeted HIV prevention strategy.
自1998年以来，澳大利亚开展了艾滋病毒和性传播感染（STI）行为监测系统（即反复进行的横断面同性恋社区定期调查，GCPS），覆盖澳大利亚六个主要司法管辖区。在本文中，我们回顾了其历史和方法，以及可用指标、其趋势及其用途。
我们描述了GCPS的设计和历史。对于指标分析，我们使用Pearson卡方检验，并在适当情况下进行趋势检验。
在澳大利亚，约90%的男同性恋者接受过艾滋病毒检测（在未感染艾滋病毒的男性中，有60%至70%）在前12个月内按照建议进行了检测。性传播感染检测水平（在前12个月内约为70%）较高，但对于性传播感染预防而言仍不足。总体而言，与固定性伴侣进行无保护肛交（UAIR）和与临时性伴侣进行无保护肛交（UAIC）的情况随时间有所增加。各司法管辖区UAIR的患病率和上升趋势相似（P趋势<0.01），而UAIC的趋势在各州有所不同：在2001 - 2008年期间，新南威尔士州的UAIC有所下降（P趋势<0.01），而其他地区有所上升（P趋势<0.01）。UAIC的趋势与艾滋病毒诊断相关。
对澳大利亚艾滋病毒/性传播感染行为监测的设计、实施和结果进行的这项审查，凸显了男同性恋者艾滋病毒/性传播感染行为监测的重要经验教训，特别是需要在不同时间和不同司法管辖区进行一致的数据收集。对系统行为监测的投入似乎有助于更好地了解艾滋病毒疫情、建立预警系统以及制定更具针对性的艾滋病毒预防策略。
