Voluntary testing and counseling (VTC) for HIV/AIDS is now widely accepted as an effective HIV prevention and control strategy among heterosexual couples in sub-Saharan Africa. The most appropriate format and venue for VTC remains a topic of debate among clinicians and public health professionals. Our research done in Lusaka, Zambia, took a tripartite approach to exploring the most acceptable format and venue for VTC: a community survey of attitudes towards VTC, a pre- and postcounseling knowledge survey, and a pilot study of same-day VTC in urban antenatal care clinics. A community survey of 181 individuals was conducted in July-August 1996 based on a structured questionnaire. A pre- and post-VTC intervention knowledge survey was conducted during the same period among 82 couples attending the Zambia-UAB HIV Research Project (ZUHRP) HIV VTC center in Lusaka. Finally, same-day HIV VTC was pilot tested in six antenatal clinic locations during February-May 1997 and June-August 1998. The community survey revealed that 98% of participants support promotion of HIV VTC in the community and 83.8% prefer the same-day testing format. The knowledge survey revealed misconceptions about discordance within a couple and perinatal transmission of HIV. Pilot testing in antenatal clinics was well received, with 84% of pregnant women requesting testing and 25% having positive HIV serologies. Women with primary school or less education, those seeking antenatal care in local clinics, and those seen before the third trimester of pregnancy were more likely to request HIV testing. Testing and counseling for HIV were shown to be feasible and effective in the antenatal clinic setting. Implementation of same-day HIV VTC in antenatal clinics is an effective strategy to prevent vertical transmission and should be expanded to include couples to leverage a decrease in heterosexual transmission as well.
自愿咨询检测(VTC)现已被广泛认为是撒哈拉以南非洲异性恋夫妇中一种有效的艾滋病毒预防和控制策略。VTC最合适的形式和地点仍是临床医生和公共卫生专业人员争论的话题。我们在赞比亚卢萨卡开展的研究采用了三方方法来探索VTC最可接受的形式和地点:对VTC态度的社区调查、咨询前后的知识调查,以及在城市产前护理诊所进行当日VTC的试点研究。1996年7月至8月,基于一份结构化问卷对181人进行了社区调查。同期,在卢萨卡参加赞比亚-阿拉巴马大学艾滋病毒研究项目(ZUHRP)艾滋病毒VTC中心的82对夫妇中进行了VTC干预前后的知识调查。最后,1997年2月至5月以及1998年6月至8月在六个产前诊所地点对当日艾滋病毒VTC进行了试点测试。社区调查显示,98%的参与者支持在社区推广艾滋病毒VTC,83.8%的人更喜欢当日检测形式。知识调查揭示了对夫妻间不一致以及艾滋病毒围产期传播的误解。产前诊所的试点测试受到好评,84%的孕妇要求检测,25%的人艾滋病毒血清学呈阳性。小学及以下学历的女性、在当地诊所寻求产前护理的女性以及在怀孕晚期之前就诊的女性更有可能要求进行艾滋病毒检测。在产前诊所环境中进行艾滋病毒检测和咨询被证明是可行且有效的。在产前诊所实施当日艾滋病毒VTC是预防垂直传播的有效策略,也应扩大到包括夫妇,以利用异性传播的减少。
