Abstract

OBJECTIVE

We examine the extent to which Ugandans accurately know their HIV status and that of their partners.

METHODS

The 2011 Uganda AIDS Indicator Survey (UAIS) was a nationally representative study of 15-59 year olds that tested 21,366 individuals for HIV. We compared self-reported HIV status with UAIS-determined HIV status for respondents. We were able to link 3285 couples in the survey, and in this group, we compared the reported HIV status of partners with that determined by UAIS. Multiple logistic regression analysis was used to identify factors associated with inaccurate knowledge of HIV status.

RESULTS

An estimated 55.8% of adult Ugandans reported having had an HIV test. Of 1495 HIV-infected Ugandans, 59.1% were unaware of their HIV infection. Among 3285 linked couples in this analysis, 273 couples (8.3%) had at least 1 infected partner, with 96 couples (2.9%) having both members infected and the remaining 177 couples (5.4%) being HIV discordant. This meant that 369 persons in the linked couple group had an HIV-infected partner. One hundred ten (29.8%) of this group knew that their partner was HIV infected. In multiple logistic regression analysis, accurately knowing that ones partner was HIV infected was strongly associated with couple HIV testing [adjusted odds ratio (AOR): 4.3, 95% confidence interval (CI): 2.2 to 8.4] and reporting oneself to be HIV positive versus reporting HIV negative (AOR: 7.3, 95% CI: 3.8 to 14.3) or HIV status unknown (AOR: 30.6, 95% CI: 3.8 to 263.4).

CONCLUSIONS

Respondents may be reporting the HIV status of their partners based on their own HIV status. Campaigns to inform people about the prevalence of serodiscordance in conjunction with further promotion of couple counseling may help increase the proportion of Ugandans who know their own HIV status and that of their partners.

摘要

目的

我们调查乌干达人准确知晓自身及性伴侣艾滋病毒感染状况的程度。

方法

2011年乌干达艾滋病指标调查（UAIS）是一项针对15至59岁人群的全国代表性研究，对21366人进行了艾滋病毒检测。我们将受访者自我报告的艾滋病毒感染状况与UAIS确定的感染状况进行了比较。我们能够在调查中关联3285对伴侣，在这组人群中，我们将伴侣报告的艾滋病毒感染状况与UAIS确定的状况进行了比较。采用多元逻辑回归分析来确定与艾滋病毒感染状况知晓不准确相关的因素。

结果

估计55.8%的成年乌干达人报告曾接受过艾滋病毒检测。在1495名感染艾滋病毒的乌干达人中，59.1%不知道自己感染了艾滋病毒。在本次分析的3285对关联伴侣中，273对伴侣（8.3%）至少有一方感染，其中96对伴侣（2.9%）双方均感染，其余177对伴侣（5.4%）一方感染另一方未感染。这意味着关联伴侣组中有369人有感染艾滋病毒的性伴侣。该组中有110人（29.8%）知道其性伴侣感染了艾滋病毒。在多元逻辑回归分析中，准确知晓性伴侣感染艾滋病毒与伴侣艾滋病毒检测密切相关[校正比值比（AOR）：4.3，95%置信区间（CI）：2.2至8.4]，且与自我报告艾滋病毒呈阳性而非报告艾滋病毒呈阴性（AOR：7.3，95%CI：3.8至14.3）或艾滋病毒感染状况未知（AOR：30.6，95%CI：3.8至263.4）相关。
