并发性行为对性传播感染传播的影响取决于性交频率、避孕套使用、关系重叠持续时间和性伴侣数量。先前的研究已经确定了不同的并发类型；然而，人们对它们的风险特征知之甚少。方法从洛杉矶社区招募年龄在18 - 30岁、感染艾滋病毒风险较高的男性（n= 261）和女性（n= 275）。参与者在12个月内完成了4次面对面访谈。伴侣关系数据被用来描述4种并发性的患病率：过渡性（2种重叠关系，其中第一种关系在第二种关系之前结束）、单日性（在另一种关系过程中持续1天的第二种关系）、包含性（第二种关系在另一种关系过程中开始和结束1天）和多重性（≥3种重叠关系）。使用多水平随机截距模型估计平均性交频率、避孕套保护行为比例、重叠总持续时间和终生性伴侣。结果基线时，47%的男性和32%的女性参与者报告在过去4个月内有任何类型的并发，26%的男性和10%的女性报告多重并发。避孕套的使用率从56%到64%不等，其中过渡性并发性行为的使用率最高（男性61%，女性68%），而性交性行为的使用率最低（男性52%，女性54%）。性交频率、总重叠和终生性伴侣也因并发类型而异。结论持续使用避孕套和反复接触的机会是高危青年并发性行为的常见特征。
BackgroundThe impact of concurrency on sexually transmitted infection transmission depends on coital frequency, condom use, duration of relationship overlap, and number of partners. Previous research has identified distinct concurrency types; however, little is known about their risk characteristics.MethodsMen (n= 261) and women (n= 275) aged 18 to 30 years at increased risk for acquiring HIV were recruited from community locations in Los Angeles. Participants completed 4 in-person interviews for 12 months. Partnership data were used to characterize the prevalence of 4 types of concurrency: transitional (2 overlapping relationships in which the first relationship ended before the second), single day (a second relationship of 1 day’s duration during the course of another relationship), contained (a second relationship> 1 day began and ended during the course of another), and multiple (≥ 3 overlapping relationships). Multilevel random intercept models were used to estimate mean coital frequency, proportion of condom-protected acts, total duration of overlap, and lifetime sex partners.ResultsAt baseline, 47% of male and 32% of female participants reported any type of concurrency in the previous 4 months, and 26% of men and 10% of women reported multiple concurrencies. Condom use ranged from 56% to 64%, with the highest use in transitional concurrency (61% for men, 68% for women) and the lowest in contained (52% for men, 54% for women). Coital frequency, total overlap, and lifetime sex partners also varied by concurrency type.ConclusionsInconsistent condom use and repeated opportunities for exposure characterize common types of concurrency among high-risk young adults.
