We examined concurrency among sexual partners reported by men who have sex with men (MSM) with recent (acute or early) HIV infection in San Diego, California (2002-2015). Partners overlapping in time in the past 3 months were considered concurrent. Logistic generalized linear mixed models were used to identify factors associated with concurrency at the partner-level. 56% (388/699) of partners were concurrent to ≥1 other partner. The odds of concurrency were higher among partners >10 years younger than the participant (vs. within 10 years of age) [adjusted odds ratio (AOR) = 2.22, 95% confidence interval (CI) 1.09-4.52], longer term partners (AOR per month = 1.02, 95% CI 1.01-1.03), and partners met online (AOR = 1.56, 95% CI 0.98-2.48). Concurrency is common among partners of recently HIV-infected MSM. Tailored HIV prevention strategies for MSM with older partners, longer term partners, and partners met online may help minimize the potential impact of concurrency on HIV transmission.
我们调查了加利福尼亚州圣地亚哥（2002 - 2015年）近期（急性或早期）感染艾滋病毒的男男性行为者（MSM）报告的性伴侣之间的同时性行为情况。过去3个月内有时间重叠的伴侣被视为同时性伴侣。采用逻辑广义线性混合模型来确定伴侣层面与同时性行为相关的因素。56%（388/699）的伴侣与≥1名其他伴侣存在同时性行为。与参与者年龄相差超过10岁的伴侣（与年龄相差在10岁以内相比）同时性行为的几率更高[调整优势比（AOR）= 2.22，95%置信区间（CI）1.09 - 4.52]，长期伴侣（每月AOR = 1.02，95% CI 1.01 - 1.03），以及在网上认识的伴侣（AOR = 1.56，95% CI 0.98 - 2.48）。同时性行为在近期感染艾滋病毒的男男性行为者的伴侣中很常见。针对有年龄较大的伴侣、长期伴侣以及在网上认识的伴侣的男男性行为者制定的艾滋病预防策略，可能有助于将同时性行为对艾滋病毒传播的潜在影响降至最低。
