DESCRIPTION (provided by applicant): Young women are at disproportionate risk of STIs and their consequences, with the highest rates of chlamydia and gonorrhea, as well as outcomes such as pelvic inflammatory disease, infertility and cervical cancer. This disease burden has a disparate on some groups of young women, such as racial/ethnic minorities and women of low socio-economic status. To date, most research and prevention programs have focused on individual- level predictors of sexual risk behavior measured at a single time point (e.g., behavioral intentions, attitudes). However, individuals' intentions to engage in risky or protective behaviors may vary across contexts and over the course of relationships. By applying a cutting-edge analytic technique to richly detailed, intensive longitudinal data, we will extend research on sexual risk behavior to address the relationship dynamics that influence these behaviors. This project will make use of data collected weekly from nearly 1,000 young women over 2.5 years, including detailed information about their relationships, sexual behavior, contraceptive use, attitudes and intentions. We will apply a novel analytic technique, the time-varying effect model, to understand women's sexual risk behavior over the course of the relationship with a sexual partner. This project has three specific aims. First, we will model patterns of young women's non-use of condoms over the course of sexual partnerships. Second, we will examine how women's intentions to use condoms differentially predict condom non-use over the course of sexual partnerships. Finally, we will delve into sources of disparities in sexual health outcomes by examining how these patterns of sexual risk behavior may differ by race/ethnicity, socioeconomic factors and urbanicity. By modeling how sexual risk behavior evolves over the course of a relationship, the proposed project will inform the creation of more effective prevention programs that are targeted to high risk populations and relationships contexts.

描述（由申请人提供）：年轻妇女的性病及其后果的风险不成比例，衣原体和淋病的发生率最高，以及骨盆炎性疾病，不育症和宫颈癌等结果。这种疾病负担对某些年轻妇女（例如种族/族裔少数民族和社会经济地位低下的妇女）的负担有分歧。迄今为止，大多数研究与预防计划都集中在一个时间点（例如行为意图，态度）上测得的性风险行为的个体预测指标。但是，个人有危险或保护行为的意图可能会在各种情况下以及在关系过程中有所不同。通过将最先进的分析技术应用于丰富的密集纵向数据，我们将扩展对性风险行为的研究，以解决影响这些行为的关系动态。该项目将利用每周收集的2.5岁年轻女性收集的数据，包括有关其关系，性行为，避孕药，态度和意图的详细信息。我们将采用一种新颖的分析技术，即时变效应模型，以了解与性伴侣关系的过程中妇女的性风险行为。该项目具有三个特定的目标。首先，我们将模拟年轻女性在性伙伴关系过程中不使用避孕套的模式。其次，我们将研究妇女使用避孕套的意图如何在性伙伴关系过程中差异预测避孕套。最后，我们将通过研究这些性风险行为的这些模式如何因种族/种族，社会经济因素和城市化的方式来探讨性健康结果差异的来源。通过建模性风险行为如何在关系过程中发展，该项目将为创建针对高风险人群和关系环境的更有效的预防计划的创建。
