采用荟萃分析方法评估了发展中国家艾滋病自愿咨询检测（VCT）在减少艾滋病危险行为方面的有效性。标准化方案用于搜索、获取和提取研究数据并对结果进行荟萃分析。7项研究符合纳入标准。与接受VCT之前的行为相比，或与未接受VCT的参与者相比，VCT接受者参与无保护性行为的可能性显著降低[OR 1.69; 95%CI 1.25-2.31]。VCT对性伴侣数量无显著影响[OR 1.22; 95%CI 0.89-1.67]。虽然这些研究结果只提供了适度的证据支持自愿咨询和检测作为一种有效的预防战略，但它们也没有否定扩大获得艾滋病毒检测和咨询服务的必要性。然而，这种扩展必须伴随着严格的评估，以测试、完善和最大限度地发挥通过艾滋病毒检测和咨询了解艾滋病毒感染状况的预防效益。
The effectiveness of HIV voluntary counseling and testing (VCT) in reducing HIV risk behaviors in developing countries was assessed using meta-analytic methods. A standardized protocol was used for searching, acquiring, and extracting study data and meta-analyzing the results. Seven studies met the inclusion criteria. VCT recipients were significantly less likely to engage in unprotected sex when compared to behaviors before receiving VCT, or as compared to participants who had not received VCT [OR 1.69; 95%CI 1.25-2.31]. VCT had no significant effect on the number of sex partners [OR 1.22; 95%CI 0.89-1.67]. While these findings provide only moderate evidence in support of VCT as an effective prevention strategy, neither do they negate the need to expand access to HIV testing and counseling services. Such expansion, however, must be accompanied by rigorous evaluation in order to test, refine and maximize the preventive benefits of learning one's HIV infection status through HIV testing and counseling.
