STD RISKS AND LATINO ADOLESCENTS' SEXUAL NETWORKS

最近的研究表明，性网络的结构 会增加个人患性传播疾病(SID)的风险 怀孕了。因此，性爱网络目前正在几个 在青少年中的研究。然而，也有专门针对这类研究的 以拉丁裔/a青少年为目标，尽管与大多数其他族裔和种族相比 在这些群体中，拉美裔青少年患性病的风险更高，并且发病率最高 怀孕的迹象。这在加州是一个特别的问题，特别是在 湾区，在那里拉丁裔是增长最快的种族群体。致信地址 这一不足，我们建议进行一项为期两年的纵向研究，以检查社会和 特派团14至19岁拉丁裔/a青少年的性网络 旧金山的一个区。我们的项目有三个具体目标：1)测量 拉丁裔/a青少年社交和性网络的规模和结构， 基线和随时间变化，包括网络结构和 与生殖健康结果(性传播疾病和怀孕)有关的成员；11)至 确定拉美裔高危性网络成员的预测因素 青少年使用源自青少年社会认知模型的因素 民族认同的发展和从问题行为理论(如 家庭、同伴和社区的影响以及独立性和对 成就)；以及iii)比较结构、性能和混合 拉丁裔/a青少年的性和社会网络矩阵与 在一个毗邻的地理区域使用来自 平行的同伴研究。为了描述社交网络和性网络的特征， 我们提出了一种以自我为中心的抽样形式，其基础是初始的、基于总体的 在不考虑感染状况的情况下招募的索引个人的随机样本 然后，这将建立在对合作伙伴进行滚雪球抽样的基础上。我们的首字母队列 受访者将由性活跃的青少年组成，他们随机地 被选中的，他们最亲密的朋友中也符合资格的一到两个 标准，以及随机选择的性不活跃的青少年 基线，但谁在研究过程中变得如此。网络将是 来自招募他们两代的性伴侣和 关于他们朋友的信息。参与者将通过以下方式接受采访 最先进的面谈技术(计算机辅助音频 自我访谈[ACASI])，并检测淋病和衣原体(使用连接酶 链式反应)和通过收集尿样怀孕。这项研究将 允许详细检查流行病学、 心理社会、行为和网络因素对性风险的影响 获得性传播疾病和怀孕的可能性。

Recent research has shown that the structure of sexual networks can increase individuals' risks for sexually transmitted diseases (SIDS) and pregnancy. Accordingly, sexual networks are currently being examined in several studies among adolescents. However, there are nonesuch studies specifically targeting Latino/a teens, even though compared to most other ethnic and racial groups, Latino teens are at increased risk for STDs and have the highest rates of pregnancy. This is a particular problem in California, and especially in the Bay Area, where Latinos represent the fastest growing ethnic group. To address this deficiency, we propose a two-year longitudinal study to examine social and sexual networks of Latino/a adolescents, 14-19 years old, from the Mission District of San Francisco. Our project has three specific aims: 1) to measure the size and structure of Latino/a adolescents' social and sexual networks, at baseline and over time, including the association between network structure and membership with reproductive health outcomes (STDs and pregnancy); 11) to identify predictors of membership in high-risk sexual networks among Latino adolescents using factors derived from the Social Cognitive Model of the Development of Ethnic Identity and from Problem Behavior Theory (such as family, peer and community influences as well as independence and desire for achievement); and III) to compare the configuration, properties, and mixing matrices of sexual and social networks of Latino/a adolescents with those of African American adolescents in a contiguous geographic area using data from a parallel, companion study. In order to characterize social and sexual networks, we propose a form of egocentric sampling based on an initial, population- based random sample of index individuals recruited without regard to infection status that then builds on snowball sampling of partners. Our cohort of initial respondents will consist of sexually active teens who have been randomly selected, one or two of their closest friends who also meet eligibility criteria, as well as randomly selected teens who are sexually inactive at baseline, but who become so over the course of the study. The network will be derived from recruitment of two generations of their sexual partners and information about their friends. Participants will be interviewed using state-of-the-art interviewing techniques (audio computer-assisted self-interview [ACASI]) and tested for gonorrhea and chlamydia (using ligase chain reaction) and pregnancy by collection of urine specimens. The study will permit detailed examination of the combined influence of epidemiologic, psychosocial, behavioral, and network factors on sexual risk taking, the acquisition of STDS, and likelihood of pregnancy.
