背景在美国，性传播感染（STI）率的明显种族差异仍然没有得到充分的解释。一个重要的因素可能是同时发生的性伴侣关系（在时间上重叠的关系），它可以比连续的一夫一妻制更快地在人群中传播性传播感染。为了确定美国妇女参与同时性伴侣关系的流行率、分布和相关因素，我们分析了1995年全国家庭增长调查中10,847名年龄在15-44岁之间的妇女报告的性伴侣关系数据。重叠的性伴侣日期通过计算机程序和视觉审查的数据来确定。自1991年1月以来，同时伴侣关系的普遍性总体为12%，目前已婚的受访者中普遍性最低（4%），而在那些以前已婚的人中普遍性最高（22%），从未结婚（19%），最低收入阶层（17%），受访时年龄为18-24岁（23%），或在12岁或13岁时第一次发生性行为（35%）。患病率在黑人中为21%，在白人中为11%，在西班牙裔中为8%，在亚裔和太平洋岛民中为6%。多因素Logistic回归分析结果显示，黑人与并发症的关系明显减弱（OR = 1.2; 95%CI = 1.1-1-4）。婚姻状况尤其与性伴侣数量密切相关;因此，黑人的结婚率较低，而性伴侣数量较多，这可能导致性传播感染率的种族差异。
Background. The marked racial disparity in sexually transmitted infection (STI) rates in the United States remains inadequately explained. One important factor may be concurrent sexual partnerships (relationships that overlap in time), which can transmit STIs more rapidly through a population than does sequential monogamy,Methods. To determine prevalence, distribution, and correlates of U.S. women's involvement in concurrent partnerships, we analyzed sexual partnership data reported by the 10,847 women, age 15-44 years, in the 1995 National Survey of Family Growth. Overlapping sexual partnership dates were determined by computer program and visual review of the data.Results. Prevalence of concurrent partnerships since January 1991 was 12% overall, Prevalence was lowest among currently married respondents (4%) and highest among those who were formerly married (22%), never married (19%), in the lowest income stratum (17%), age 18-24 years when interviewed (23%), or who first had sexual intercourse at age 12 or 13 (35%). Prevalence was 21% among blacks, 11% among whites, 8% among Hispanics, and 6% among Asian American and Pacific Islanders. Multiple logistic analysis substantially weakened the relationship between concurrency and black race (OR = 1.2; 95% Cl = 1.1-1-4).Conclusions. Marital status in particular is strongly related to concurrency; thus, lower marriage rates among blacks and the associated higher concurrency of sexual partners may contribute to racial disparities in STI rates.
