Concurrent partnerships accelerate dissemination of STIs. Most investigations of the features of concurrent partnerships have focused on higher risk subpopulations.
To assess condom use and the duration of concurrent sexual partnerships among men in the United States.
Analysis of concurrent sexual partnerships among men in the 2002 National Survey of Family Growth. We classified pairs of concurrent partnerships into 3 types: transitional, contained, and experimental concurrency, and assessed the duration of overlap. We also report the distribution of condom use at the last sexual intercourse with neither, one or both concurrent partners of each pair and characteristics of men more likely to have used condoms with neither sex partner.
The duration of overlap was <1 month in 32%, 1 to 3 months in 19%, and >12 months in 25% of concurrency pairs. Half (55%) of the pairs (whites, 64%; blacks, 41%) involved unprotected sex at the last sexual intercourse with at least 1 partner. The 35% of men who were more likely to use condoms with neither sex partner at the last sexual intercourse were older, white (48%), married/cohabitating (55%), and during the previous 12 months were incarcerated (49%), or used crack/cocaine (51%).
Although blacks generally experience higher rates of STIs and HIV, in this representative sample of men in the United States, blacks in concurrent partnerships seemed to use the only available protection (condoms) against infection (apart from abstinence) more than other racial/ethnic groups. Continued investigation of features of sexual partnership patterns is critical for curbing STI and HIV transmission.
同时存在多个性伴侣会加速性传播感染的传播。大多数关于同时存在多个性伴侣特征的调查都集中在高风险亚人群体上。
评估美国男性同时存在的性伴侣关系中的避孕套使用情况以及持续时间。
对2002年全国家庭成长调查中男性的同时存在的性伴侣关系进行分析。我们将同时存在的性伴侣关系对分为3种类型:过渡型、包含型和试验性同时存在多个性伴侣,并评估重叠持续时间。我们还报告了在与每对性伴侣中的一方、双方或均无进行最后一次性交时避孕套的使用分布情况,以及更有可能与双方性伴侣都不使用避孕套的男性特征。
在32%的同时存在多个性伴侣关系对中,重叠持续时间不到1个月;19%的关系对重叠持续时间为1至3个月;25%的关系对重叠持续时间超过12个月。一半(55%)的关系对(白人占64%;黑人占41%)在与至少1个性伴侣进行最后一次性交时存在无保护性行为。在最后一次性交时更有可能与双方性伴侣都不使用避孕套的35%的男性年龄较大,为白人(48%),已婚/同居(55%),并且在前12个月内曾被监禁(49%)或使用快克/可卡因(51%)。
尽管黑人一般性传播感染和艾滋病毒感染率较高,但在这个具有代表性的美国男性样本中,处于同时存在多个性伴侣关系中的黑人似乎比其他种族/族裔群体更多地使用唯一可用的感染防护措施(避孕套)(除禁欲外)。持续调查性伴侣关系模式的特征对于遏制性传播感染和艾滋病毒传播至关重要。
