This study critically examines serological survey data for HIV infection in selected populations in Bali, Indonesia. Sero-survey data reported by the Bali Health Office between 2000 and 2010 were collated, and provincial health staff were interviewed to gain a detailed understanding of survey methods. Analysis of time series restricted to districts that have used the same sampling methods and sites each year indicates that there has been a steady decline in HIV prevalence among prisoners, from 18.7% in 2000 to 4.3% in 2010. In contrast, HIV prevalence among women engaged in sex work increased sharply: from 0.62% in 2000 to 20.2% in 2010 (brothel based), and from 0% in 2000 to 7.2% in 2010 (non-brothel based). The highest prevalence was recorded among people who injected drugs. Recent surveys of gay men and transvestites also found high prevalences, at 18.7% and 40.9%, respectively. Review of the methodology used in the surveys identified inconsistencies in the sampling technique, sample numbers and sites over time, and incomplete recording of individual information about survey participants. Attention to methodological aspects and incorporation of additional information on behavioural factors will ensure that the surveillance system is in the best position to support prevention activities.
本研究严格审查了印度尼西亚巴厘岛特定人群中艾滋病毒感染的血清学调查数据。整理了巴厘岛卫生局在2000年至2010年期间报告的血清学调查数据，并对省级卫生工作人员进行了访谈，以详细了解调查方法。对每年采用相同抽样方法和地点的地区进行时间序列分析表明，囚犯中的艾滋病毒流行率呈稳步下降趋势，从2000年的18.7%降至2010年的4.3%。相比之下，从事性工作的女性中的艾滋病毒流行率急剧上升：2000年为0.62%，2010年（基于妓院）升至20.2%，2000年为0%，2010年（非妓院）升至7.2%。注射吸毒者中的流行率最高。最近对男同性恋者和易装癖者的调查也发现了较高的流行率，分别为18.7%和40.9%。对调查中使用的方法进行审查发现，随着时间的推移，抽样技术、样本数量和地点存在不一致之处，并且关于调查参与者的个人信息记录不完整。关注方法学方面并纳入关于行为因素的更多信息将确保监测系统处于最佳位置，以支持预防活动。
