In Ethiopia, the number of HIV tests administered doubled from 2007 to 2008. However, very little is known about the number of clients testing repeatedly in one year, or their motivations for doing so. We examine repeat HIV testing among 2,027 Ethiopian women attending eight VCT facilities in 2008. Multivariate logistic regression was used to examine associations between repeat HIV testing and demographic, behavioral, and psychosocial characteristics, as well as HIV status. Nearly 40% of clients had tested previously for HIV. Women with high sexual risk are nearly four times more likely than those with no sexual risk to have tested previously, but HIV prevalence was lower among repeat testers (6.5%) than first-time testers (8.5%). Moderate perceived vulnerability, or feeling powerless to prevent HIV infection, is associated with a 50% increased likelihood of being a repeat tester. High perceived behavioral risk is associated with a 40% reduction in the likelihood a woman is testing for at least the second time. Costs associated with repeat testing should be balanced against identification of new HIV cases and prevention benefits.
在埃塞俄比亚，2007 年至 2008 年期间，艾滋病毒检测数量增加了一倍。然而，人们对一年内接受重复检测的客户数量及其重复检测的动机知之甚少。我们调查了 2008 年在 8 个 VCT 机构就诊的 2027 名埃塞俄比亚妇女的重复艾滋病毒检测情况。多变量逻辑回归用于检查重复艾滋病毒检测与人口统计学、行为和社会心理特征以及艾滋病毒状况之间的关联。近 40%的客户之前曾接受过艾滋病毒检测。性风险高的女性重复检测的可能性是无性风险女性的近四倍，但重复检测者（6.5%）的艾滋病毒流行率低于首次检测者（8.5%）。中度感知脆弱性，即无力预防艾滋病毒感染，与重复检测者的可能性增加 50%相关。高感知行为风险与女性至少第二次检测的可能性降低 40%相关。重复检测的相关成本应与新的艾滋病毒病例的发现和预防效益相平衡。
