This proposed R03 project focuses on an understudied but important question: how is hormonal contraceptive method use associated with the frequency of sexual intercourse among mixed-sex couples? Hormonal contraception is a safe and effective way to avoid undesired pregnancy, and 80% of sexually active women have used the oral contraception pill (Guttmacher 2020). However, some evidence suggests that sexual side effects of hormonal contraception – including decreased arousal and sexual functioning – may lead some couples to discontinue its use (Higgins & Smith 2016; Sanders et al. 2018), leaving them vulnerable to an undesired pregnancy. Very little research has described the links between hormonal contraceptive use and sexual intercourse, and the studies that have explored these links have been undermined by cross-sectional designs, small samples, and/or neglect of the intimate relationship context. We propose a state-of-the art statistical analysis of existing intensive longitudinal survey data. The survey data are from 953 young women (ages 18-22) who participated in an NICHD-funded project, the Relationship Dynamics and Social Life (RDSL) study, which collected weekly surveys on intimate relationships, mixed-sex sexual intercourse, contraceptive use, and pregnancy for 2.5 years beginning at age 18 or 19. This data—with repeated surveys within each relationship—provides the first opportunity to describe the interconnections between heterosexual intercourse and hormonal contraceptive use across the course of these relationships. We have three specific aims for this project. First, we will estimate logistic regression models of the weekly probability of sexual intercourse, using a within-between fixed-effects/random-effects (hybrid) specification, to test our hypothesis that a mixed-sex couple’s probability of having sexual intercourse is lower when they are using a hormonal contraceptive method than when that same couple is not using a hormonal method. Second, we will use the same methods to test our hypothesis that the consequences of hormonal contraceptive use for sexual frequency will accumulate over time, net of relationship duration. Third, we will use multilevel (mixed effects) models, which easily permit the inclusion of cross-level interactions between upper-level (individual/relationship) characteristics and hormonal contraceptive use as predictors of sexual frequency, to test our hypothesis that the association between hormonal contraceptive use and sexual frequency differs depending on the characteristics of the intimate relationship. We propose a complementary, uniquely qualified investigator team: Dr. Jennifer Barber, Professor of Sociology and Senior Scientist at the Kinsey Institute (PI of RDSL project; expert in intimate relationships and contraceptive use) and Dr. Shari Blumenstock, a post-doctoral fellow at the Kinsey Institute (expert in sexual behavior and intimate relationships).

这个拟议的 R03 项目重点关注一个尚未充分研究但很重要的问题：荷尔蒙如何 避孕方法的使用与异性伴侣的性交频率有关吗？ 激素避孕是避免意外怀孕的安全有效方法，80% 的性活跃者 女性已使用口服避孕药（Guttmacher 2020）。然而，一些证据表明 激素避孕药的性副作用 - 包括性唤起和性功能下降 - 可能会导致 一些夫妇停止使用它（Higgins & Smith 2016；Sanders et al. 2018），使他们容易受到 意外怀孕。很少有研究描述激素避孕药的使用与 性交，以及探索这些联系的研究已被横断面的破坏 设计、小样本和/或忽视亲密关系背景。 我们提出对现有密集纵向调查数据进行最先进的统计分析。调查 数据来自 953 名年轻女性（18-22 岁），她们参加了 NICHD 资助的项目“关系” 动态和社交生活（RDSL）研究，每周收集有关亲密关系、男女混合的调查 从 18 岁或 19 岁开始的 2.5 年性交、避孕措施和怀孕。该数据 — 对每种关系进行重复调查——提供了描述相互关系的第一个机会 在这些关系过程中异性性交和激素避孕药的使用之间的关系。 我们对该项目有三个具体目标。首先，我们将估计每周的逻辑回归模型 性交的概率，使用固定效应/随机效应（混合）规范之间的范围，以 检验我们的假设，即异性伴侣在以下情况下发生性行为的可能性较低 使用激素避孕方法与同一对夫妇不使用激素避孕方法相比。第二， 我们将使用相同的方法来检验我们的假设，即使用激素避孕药的后果 性频率会随着时间的推移而积累，扣除关系持续时间。第三，我们将使用多级（混合 效果）模型，很容易允许包含上层之间的跨层交互 （个人/关系）特征和激素避孕药的使用作为性频率的预测因素， 检验我们的假设，即激素避孕药的使用与性频率之间的关联不同 取决于亲密关系的特点。 我们建议建立一个互补的、具有独特资格的研究团队：詹妮弗·巴伯 (Jennifer Barber) 博士，教授 金赛研究所社会学和高级科学家（RDSL 项目的 PI；亲密关系和 避孕药具的使用）和金赛研究所博士后研究员 Shari Blumenstock 博士（性专家） 行为和亲密关系）。
