The sexual behaviors of HIV/sexually transmitted infection (STI) prevention intervention participants can be assessed on a partner-by-partner basis: in aggregate (i.e., total numbers of sex acts, collapsed across partners) or using a combination of these two methods (e.g., assessing five partners in detail and any remaining partners in aggregate). There is a natural trade-off between the level of sexual behavior detail and the precision of HIV/STI acquisition risk estimates. The results of this study indicate that relatively simple aggregate data collection techniques suffice to adequately estimate HIV risk. For highly infectious STIs, in contrast, accurate STI risk assessment requires more intensive partner-by-partner methods.
HIV/性传播感染 (STI) 预防干预参与者的性行为可以按伴侣为单位进行评估:总体上(即,跨伴侣的总性行为次数)或使用这两种方法的组合(例如,详细评估五个伴侣,而其余伴侣则总体上评估)。性行为细节水平和 HIV/STI 感染风险估计的精确性之间存在自然的权衡。本研究的结果表明,相对简单的总体数据收集技术足以充分估计 HIV 风险。相比之下,对于高度传染性的 STI,准确的 STI 风险评估需要更密集的伴侣为单位的方法。
