Abstract

OBJECTIVE

To evaluate trends in HIV-1 seroprevalence in Thailand.

DESIGN

HIV-1 serosurvey of successive cohorts of young Thai men entering service with the Royal Thai Army (RTA) between November 1989 and November 1994.

METHODS

In November 1989, the RTA Medical Department began routine HIV-1-antibody screening of men who were selected by lottery for conscription. Between November 1989 and November 1994, 311,108 young men were screened at induction. Demographic data were collected between November 1991 and May 1993 and again in November 1994.

RESULTS

The seroprevalence of HIV-1 among conscripts nationwide increased rapidly from 0.5% in 1989 to 3.5% in 1992 and reached 3.7% in 1993. In 1994, the overall prevalence decreased to 3.0%. The decrease was greatest in the upper North (from 12.4% in 1992 to 7.9% in 1994), where the prevalence has been the highest. However, decreases were observed in men from all regions of residence in the country, from both rural and urban areas, and at all educational levels.

CONCLUSIONS

The decline in prevalence suggests declining incidence and that HIV control programs in Thailand are having an impact on the HIV epidemic.

摘要

目的

评估泰国HIV-1血清流行率的趋势。

设计

对1989年11月至1994年11月期间陆续进入泰国皇家军队（RTA）服役的年轻泰国男性队列进行HIV-1血清学调查。

方法

1989年11月，RTA医务部开始对通过抽签选定应征入伍的男性进行常规HIV-1抗体筛查。在1989年11月至1994年11月期间，311,108名年轻男性在入伍时接受了筛查。人口统计学数据于1991年11月至1993年5月收集，并于1994年11月再次收集。

结果

全国应征入伍者中HIV-1的血清流行率从1989年的0.5%迅速上升至1992年的3.5%，并在1993年达到3.7%。1994年，总体流行率降至3.0%。北部地区下降幅度最大（从1992年的12.4%降至1994年的7.9%），该地区的流行率一直是最高的。然而，该国所有居住地区的男性，包括农村和城市地区以及所有教育水平的男性，血清流行率均有所下降。
