我们调查了了解艾滋病毒状况对艾滋病毒/艾滋病相关期望和性行为的中期因果影响。我们的分析记录了一些关于了解自己或配偶的艾滋病毒状况的影响的意想不到的结果。例如，收到艾滋病毒阴性检测结果意味着对两年后艾滋病毒呈阳性的主观期望更高，而且个人在了解自己的艾滋病毒状况后，往往对自己的艾滋病毒状况有更大的预测误差。如果HIV阴性夫妇中的个人也知道了他们配偶的状况，这些影响就会消失。在行为结果方面，我们的分析证明，与不了解自己状况的人相比，了解自己状况的艾滋病毒阳性者报告的伴侣更少，使用避孕套的频率更高。在HIV阴性夫妇的已婚受访者中，只了解自己的状况会增加危险行为，而同时了解两种状况会降低危险行为。此外，在血清不协调的夫妇中，了解到这两种状态的人更有可能报告使用了避孕套。总体而言，我们的分析表明，无论是通过夫妻检测还是通过配偶交流，确保配偶双方了解对方的艾滋病毒状况，在高发环境中可能是有益的。
We investigate the causal impact of learning HIV status on HIV/AIDS-related expectations and sexual behavior in the medium run. Our analyses document several unexpected results about the effect of learning one's own, or one's spouse's, HIV status. For example, receiving an HIV-negative test result implies higher subjective expectations about being HIV-positive after two years, and individuals tend to have larger prediction errors about their HIV status after learning their HIV status. If individuals in HIV-negative couples also learn the status of their spouse, these effects disappear. In terms of behavioral outcomes, our analyses document that HIV-positive individuals who learned their status reported having fewer partners and using condoms more often than those who did not learn their status. Among married respondents in HIV-negative couples, learning only one's own status increases risky behavior, while learning both statuses decreases risky behavior. In addition, individuals in sero-discordant couples who learned both statuses are more likely to report some condom use. Overall, our analyses suggest that ensuring that each spouse learns the HIV status of the other, either through couple's testing or through spousal communication, may be beneficial in high-prevalence environments.
