We review the relationship between polygyny and HIV and identify a positive individual-level correlation, and a negative ecological correlation. We subsequently examine two mechanisms that contribute to the individual-level correlation. First, we find that men in polygynous marriages have more extramarital sex than men in monogamous unions (both in terms of self reports and in terms of spousal reports of the suspicion of adultery). Second, we find evidence of adverse selection of HIV positive women into polygynous unions via an investigation of the relationship between marriage order and polygyny status. We conclude with reflections about possible explanations for the distinct individual and ecological correlations.
我们回顾了一夫多妻制与艾滋病病毒之间的关系，确定了个体层面的正相关以及生态层面的负相关。随后，我们研究了导致个体层面相关性的两种机制。首先，我们发现一夫多妻制婚姻中的男性比一夫一妻制婚姻中的男性有更多的婚外性行为（无论是自我报告还是配偶对通奸怀疑的报告）。其次，通过调查婚姻顺序与一夫多妻制状况之间的关系，我们找到了艾滋病病毒呈阳性的女性被逆向选择进入一夫多妻制婚姻的证据。我们最后思考了个体和生态层面不同相关性的可能解释。
