目的：当前分析的目的是检查美国大约10年期间异性性伴侣分布的亚组差异，以确定可能为性传播感染研究和预防提供信息的模式。方法：数据来自2002年和2011-2013年全国家庭增长调查，这是一项基于概率的美国家庭调查，重点关注性健康和生殖健康。这项分析中包括的措施是一生中的异性性伴侣和过去一年的异性性伴侣。对男性和女性分别进行分析。所有的分析都进行了R和R-工作室的“调查”包，集中在中位数，第80，和第95四分位数。结果：在2002年，有显着差异，男性和女性之间的终身性伴侣的中位数与男性报告更多的终身伴侣。然而，在2011-2013年的数据中，这些差异不再显著。尽管如此，调查结果表明，前20%和前5%的男性报告的终身伴侣明显多于女性。相比之下，在过去的一年中，合作伙伴保持相对不变的男子和women.Conclusions：这些研究结果表明，有重要的变化，在2002年和2011-2013年之间的性伴侣的分布有影响性传播感染的预防。妇女和男子的终身伴侣中位数不再不同：然而，男子终身伴侣的分布变得更加不平衡。
Objective: The purpose of the current analysis is to examine subgroup differences in the distribution of opposite-sex sex partners in the United States across an approximate 10-year period to identify patterns that may inform sexually transmitted infection research and prevention.Methods: Data were drawn from the 2002 and 2011-2013 National Survey of Family Growth, a US probability-based household survey focusing on sexual and reproductive health. The measures included in this analysis were lifetime opposite-sex sex partners and opposite-sex sex partners in the past year. Analyses were conducted separately for men and women. All analyses were conducted in R and R-studio with the "survey" package, focusing on medians, the 80th, and 95th quartile.Results: In 2002, there were significant differences between men and women in median number of lifetime sex partners with men reporting more lifetime partners. However, in the 2011-2013 data, these differences are no longer significant. Still, the findings suggest that the top 20% and top 5% of men are reporting significantly more lifetime partners than their female counterparts. In comparison, partners in the past year remain relatively unchanged for both men and women.Conclusions: These findings suggest that there were important changes in the distribution of sex partners between 2002 and 2011-2013 that have implications for sexually transmitted infection prevention. Median lifetime partners are no longer different for women and men: however, the distribution of lifetime partners among men is becoming even more skewed.
