艾滋病毒预防方案成功的一个关键指标是女性性工作者（FSW）性行为受到避孕套保护的数量。这项措施通常依赖于联邦社会工作局的报告，这可能是有偏见的。我们研究了五个卡纳塔克邦地区的安全套可用性数据，以估计安全套可能保护的FSW性行为的比例。财政、方案、人口、避孕套和避孕药具数据来自政府和非政府来源、调查和艾滋病毒预防方案。性行为数据来自一般人口和FSW调查。我们在敏感性分析中研究了四种情况，每种情况都假设性工作者可能使用的避孕套比例不同。2004年，所有女性性工作者性行为中可能使用安全套的比例为3%-36%，2008年为56%-96%。两种最现实的情况是，对私营部门可能购买的用于与FSW以外的性行为的避孕套数量进行打折，结果表明，2004年，16-24%的FSW性行为可以得到避孕套的保护，2008年上升到77-85%。这些数据表明，2004年在这些卡纳塔克邦地区，安全套的供应量相对于女性性工作者性行为的数量来说是很低的，但在随后的4年里大幅上升。 安全套可用性数据可用于与其他可用数据（如自我报告的安全套使用情况）进行三角测量，以提供关于受安全套保护的FSW性行为数量的一系列可能性。
A key indicator of success of HIV prevention programmes is the number of female sex worker (FSW) sex acts protected by condoms. This measure usually relies on FSW reports, which may be biased. We examined condom availability data in five Karnataka districts to estimate the proportion of FSW sex acts potentially protected by condoms. Financial, programme, population, condom and contraceptive data were obtained from governmental and non-governmental sources, surveys and HIV prevention programmes. Sexual behaviour data were obtained from general population and FSW surveys. We examined four scenarios in a sensitivity analysis, each one assuming different proportions of available condoms that might have been used by sex workers. Possible condom use rates for all FSW sex acts ranged from 3%–36% in 2004 to 56%–96% in 2008. The two most realistic scenarios that discounted the number of private sector condoms that might have been bought for sex acts other than with FSWs showed that 16–24% of FSW sex acts could have been protected by condoms in 2004 rising to 77–85% in 2008. These data suggest that condom availability in these Karnataka districts in 2004 was low in relation to the number of FSW sex acts, but rose substantially over the ensuing 4 years. Condom availability data can be useful for triangulation with other available data, such as self-reported condom use, to provide a range of possibilities regarding the number of FSW sex acts protected by condoms.
