Size estimates of key populations at higher risk of HIV exposure are recognized as critical for understanding the trajectory of the HIV epidemic and planning and monitoring an effective response, especially for countries with concentrated and low epidemics such as those in Asia.
To help countries estimate population sizes of key populations, global guidelines were updated in 2011 to reflect new technical developments and recent field experiences in applying these methods.
In September 2013, a meeting of programme managers and experts experienced with population size estimates (PSE) for key populations was held for 13 Asian countries. This article summarizes the key results presented, shares practical lessons learnt and reviews the methodological approaches from implementing PSE in 13 countries.
It is important to build capacity to collect, analyse and use PSE data; establish a technical review group; and implement a transparent, well documented process. Countries should adapt global PSE guidelines and maintain operational definitions that are more relevant and useable for country programmes. Development of methods for non-venue-based key populations requires more investment and collaborative efforts between countries and among partners.
对面临更高艾滋病病毒暴露风险的重点人群规模进行估计，被认为对于了解艾滋病病毒疫情的发展轨迹以及规划和监测有效应对措施至关重要，尤其是对于像亚洲国家那样存在集中和低流行情况的国家。
为帮助各国估计重点人群的规模，2011年对全球指南进行了更新，以反映新的技术发展以及应用这些方法的最新实地经验。
2013年9月，为13个亚洲国家召开了一次由有重点人群规模估计经验的项目经理和专家参加的会议。本文总结了会上提出的关键成果，分享了实际经验教训，并回顾了在13个国家实施重点人群规模估计的方法。
建立收集、分析和使用重点人群规模估计数据的能力、设立一个技术审查小组以及实施一个透明且记录完善的流程很重要。各国应调整全球重点人群规模估计指南，并维持对国家项目更具相关性和实用性的操作定义。开发针对非场所型重点人群的方法需要更多投资以及各国之间和合作伙伴之间的协作努力。
