Arguments for population-based research on patterns of sexual behavior are reviewed, and survey data are used to illustrate the insights that can be gained from such research.
Reports of sexual behavior obtained in surveys of large probability samples of the U.S. population are analyzed and compared to make inferences about changes in the age of onset of sexual intercourse and the patterns of heterosexual and same-gender sexual behaviors of American men and women who entered adulthood during the period from 1930 to 1990.
Strong trends are documented for both a decline in the reported age at first heterosexual intercourse and an increase in the numbers of heterosexual partners reported during adulthood. Similar evidence on patterns of same-gender contact indicate a relatively stable prevalence of reported male-male contact for cohorts of men born from the 1930s through the 1960s. Preliminary analyses suggest, however, that there has been a substantial increase in the proportion of women reporting female-female sexual contact during adulthood. Although the analyses require refinement, it appears that the prevalence of reported female-female contact may have increased by a factor of 3 to 4 for cohorts of women born between the 1930s and the 1960s.
Although the trends in reported behaviors are robust, inferences about behavior, pre se, rest on the assumption that reporting biases were equivalent across cohorts. Methodological challenges in the interpretation of such findings and new technologies for conducting such research are described.
回顾基于人群的性行为模式研究的论据，并使用调查数据来说明此类研究可获得的见解。
分析并比较在美国人群大概率样本调查中获得的性行为报告，以推断1930年至1990年期间成年的美国男性和女性首次性交年龄的变化以及异性恋和同性性行为模式。
记录到明显趋势，即首次异性性交报告年龄下降，成年期报告的异性伴侣数量增加。关于同性接触模式的类似证据表明，20世纪30年代至60年代出生的男性群体中，报告的男男性接触患病率相对稳定。然而，初步分析表明，成年期报告有女女性接触的女性比例大幅增加。尽管分析需要完善，但似乎20世纪30年代至60年代出生的女性群体中，报告的女女性接触患病率可能增加了3至4倍。
尽管报告行为的趋势很明显，但对行为本身的推断基于各队列报告偏差相同的假设。描述了此类研究结果解释中的方法学挑战以及进行此类研究的新技术。
