Individuals who engage in regular sexual intercourse are more likely to report good overall quality of life. Studies of sexuality in adolescents have focused on high-risk behaviors whereas similar studies in older adults have focused on sexual dysfunction. Given a paucity of data on the sexual behaviors of young adults and the possibility of important relationships between sexuality and overall health, we sought to determine factors that influence the frequency of intercourse in adult men and women in the United States.
To identify factors related to coital frequency in young and middle-aged adults.
We analyzed data from the male and female sample of the 2002 National Survey of Family Growth to examine frequency of sexual intercourse among Americans aged 25-45 years (men: N = 2,469; women: N = 5,120).
Multivariable negative binomial regression modeling was used to test for independent associations between the frequency of sexual intercourse and demographic, socioeconomic, and anthropometric variables.
In this study, men and women between the ages of 25 and 45 have sex a mean 5.7 and 6.4 times per month, respectively. Being married significantly increased coital frequency for women but has no effect on male coital frequency. Increased height, less than high school education, and younger age were predictive of increased sexual frequency in men. Pregnancy was associated with significantly lower coital frequency for both men and women. No association was shown between self-reported health status and coital frequency on multivariable analysis.
Among young male adults, coital frequency is associated with specific socioeconomic, demographic, and anthropomorphic characteristics. Sexual frequency in women does not appear to be influenced by such factors. Self-reported health is not predictive of sexual activity in this age group.
经常进行性行为的人更有可能报告整体生活质量良好。青少年性行为的研究侧重于高危行为，而老年性行为的研究则侧重于性功能障碍。鉴于年轻人的性行为数据不足，以及性行为与整体健康之间可能存在重要关系，我们试图确定影响美国成年男性和女性性交频率的因素。
确定与年轻和中年成年人性交频率相关的因素。
我们分析了 2002 年全国家庭增长调查中男性和女性样本的数据，以检查 25-45 岁美国人性交频率（男性：N=2469；女性：N=5120）。
使用多变量负二项回归模型检验性交频率与人口统计学、社会经济和人体测量学变量之间的独立关联。
在这项研究中，25 至 45 岁的男性和女性每月平均进行 5.7 次和 6.4 次性行为。已婚对女性的性交频率有显著影响，但对男性没有影响。身高增加、未接受过高中教育和年龄较小与男性的性频率增加有关。怀孕与男性和女性的性交频率显著降低有关。在多变量分析中，自我报告的健康状况与性交频率之间没有关联。
在年轻男性成年人中，性交频率与特定的社会经济、人口统计学和人体测量特征有关。女性的性频率似乎不受这些因素的影响。在这个年龄组中，自我报告的健康状况并不能预测性行为。
