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（SIDS）的风险， 怀孕因此，目前正在若干国家审查性网络， 青少年的研究。然而，有一些特殊的研究， 针对拉丁美洲/a青少年，即使与大多数其他种族和种族相比， 拉丁裔青少年患性病的风险增加， 怀孕。这是加州的一个特殊问题，尤其是在 海湾地区，拉丁裔代表增长最快的种族群体。解决 针对这一不足，我们提出了一项为期两年的纵向研究， 拉丁美洲/a青少年的性网络，14-19岁，来自使命 旧金山弗朗西斯科区。我们的项目有三个具体目标：1）测量 拉丁美洲/a青少年社交和性网络的规模和结构， 基线和随着时间的推移，包括网络结构和 生殖健康结果（性病和怀孕）; 11） 确定拉丁美洲人中高危性网络成员预测因素 青少年使用来自社会认知模型的因素， 从问题行为理论（如 家庭、同龄人和社区的影响以及独立性和渴望 实现）;和III）比较配置，属性，和混合 拉丁美洲/a青少年的性和社交网络矩阵与 非裔美国青少年在邻近的地理区域使用的数据，从一个 平行的同伴研究为了描述社交网络和性网络， 我们提出了一种以自我为中心的抽样形式， 不考虑感染状况而招募的指数个体的随机样本 然后建立在对伴侣的滚雪球抽样上。我们的初始队列 受访者将由性活跃的青少年组成，他们随机 选择，一个或两个最亲密的朋友谁也符合资格 标准，以及随机选择的青少年谁是性不活跃， 但在研究过程中变得如此。该网络将 通过招募两代性伴侣， 关于他们朋友的信息。与会者将接受采访，使用 最先进的面谈技术（音频、计算机辅助 自我访谈[ACASI]），并进行淋病和衣原体检测（使用连接酶 连锁反应）和妊娠。这项研究将 允许详细检查流行病学， 社会心理、行为和网络因素对性冒险的影响， 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.
