Epidemiologic and behavioral survey of HIV/AIDS in Cambodia

1995和1996财政年度在柬埔寨首都地区对商业性工作者及其嫖客的性行为进行了研究。今年，在柬埔寨Bantey Mean Chey省进行了广泛的研究。为探讨性行为与HIV/STDA感染的关系，本研究对暗娼进行了HIV抗体、乙肝B抗原（HB-Ag）、乙肝抗体（HB-Ab）、沙眼衣原体抗体、TPHA检测，并对暗娼及其嫖客的性行为进行了调查。1997年6月，柬埔寨合作研究人员完成了性行为调查。采用问卷调查法对204名直接性工作者、96名间接性工作者和200名嫖客进行调查。8月，日本鸟取大学的研究人员从柬埔寨邀请了一名研究人员对这些数据进行了分析。柬埔寨研究人员在金边进行了HIV筛查试验（EIA）、TPHA、HB-Ag、HB-Ab的血清学检查。DCSW中HIV（EIA）、TPHA、HB-Ag、HB-Ab阳性率分别为54%、8%、9%、35%。在ICSW中分别占23%、3%、5%和34%。DCSW和ICSW中TPHA阳性率分别为11.2%和9.5%，在日本进行了HIV确认试验（Western-Blot）和沙眼衣原体抗体（CT-Ab）血清学检查。DCSW和ICSW的CT-Ab阳性率分别为81.7%和55.3%。DCSW和ICSW中HIV感染者CT-Ab阳性率分别为89.9%和85.7%。这一结果提示HIV与衣原体感染的关系。

Study of sexual behavior of commercial sex workers (CSWs) and their clients was performed in the capital region of Cambodia in fiscal 1995 and 1996. In this year, expansive study was performed in Bantey Mean Chey province, Cambodia. In order to identify the relationship between sexual behavior and HIV/STDA sero-prevalence, the study surveyed HIV antibody, Hepatitis B antigen (HB-Ag) and antiboddy (HB-Ab) Chlamydia trachomatis antibode, and TPHA for the CWSs, in addition to sexual behavior of CSWs and their clients. Survey on sexual behavior was finished by Cambodian cooperative researchers in Jun 1997. Data were gathered in a questionnaire survey of 204 direct commercial sex workers (DCSWs), 96 Indirect commercial sex workers (ICSWs), and 200clients. A researcher who was invited from Cambodia analyzed these data with Japanese researchers at Tottori University in August.Serological examination of HIV screening test (EIA), TPHA,HB-Ag.HB-Ab were performed by Cambodian researchers in Phnom-Penh. Sero-positive rate of HIV (EIA), TPHA,HB-Ag, HB-Ab among DCSWs were 54%, 8%, 9% and 35%, respectively. The rate of them among ICSWs were 23%, 3%.5%, and 34%, respectively. Positive rate of TPHA among DCSWs and ICSWs who infected with HIV were 11.2% and 9.5%, respectively.Serological examination of HIV confirmation test (Western-Blot) and Chlamydia trachomatis antibody (CT-Ab) were performed in Japan. Sero-positive rate of CT-Ab among DCSWs and ICSWs were 81.7% and 55.3%, respectively. Positive rate of CT-Ab among DCSWs and ICSWs who infected with HIV were 89.9% and 85.7%, respectively. This result was suggestive about the relation of HIV and Chlamydia infection.
