项目摘要

DESCRIPTION (provided by applicant): Despite the prevalence of poverty in many cities, the study of extremely poor inner-city residents remains relatively neglected. This is particularly the case for African American adolescents living in extreme poverty, who arguably are at the greatest risk for negative health and life outcomes. We focus on this particularly vulnerable population, testing methodological assumptions about the Mobile Youth Survey (MYS), a multiple cohort longitudinal study of adolescents living in the Mobile, AL, Metropolitan Statistical Area. The MYS is one of the largest studies of its kind; it was begun in 1998 and represents approximately 26,700 data points collected from approximately 9,000 respondents over the past 11 years. It also uses one of the most impoverished samples reported in the literature: Median household income (1990 Census) for the neighborhoods studied was $5,190 per year, and 73% of residents in these neighborhoods lived below the poverty level. Over the years, the MYS has received funding from a variety of sources, each with a different set of goals and priorities. As a result, our sampling plan was not strictly random, but used a mixed strategy that attempted to sample as much of the population of adolescents from these neighborhoods as possible. We believe that the sample is representative, and that missing data patterns are random. However, before the MYS data can achieve its full potential, we must test these assumptions. Thus, the first two aims of this study are to assess (a) the representativeness of the MYS sample, and (b) patterns of missing data to determine whether they are Missing at Random. We are fortunate to have school records from the Mobile County Public School System and lease information from the Mobile Housing Board, which we will use to supplement the MYS data in these analyses. A third aim considers whether dropout in the MYS is higher for respondents who have engaged in sexual, drug-related, and/or violent behaviors than for respondents who have not. This is an important question that will help us not only better understand the MYS sample but also provide useful information for studying other at-risk adolescent populations. PUBLIC HEALTH RELEVANCE: The past decade has witnessed considerable progress toward many of the public health goals developed in Healthy People 2010, but others seem to defy efforts to achieve them. Tragically, many of these gains have left those living in poverty untouched, with morbidity and mortality remaining unacceptably high-particularly among inner-city youth. This project tests several methodological and substantive assumptions about the Mobile Youth Survey, an 11-year longitudinal study of very impoverished African American adolescents, to determine its suitability for studying development and risk behavior in this population.

描述（由申请人提供）：尽管许多城市的贫困率盛行，但对极端城市居民的研究仍然相对忽视。对于生活在极端贫困中的非裔美国青少年来说，情况尤其如此，他们可以说是负面健康和生活成果的最大风险。我们专注于这个特别脆弱的人群，测试有关移动青年调查（MYS）的方法论假设，这是一项对居住在Mobile，Al，Metropolitan统计领域的青少年的纵向研究。 Mys是同类研究中最大的研究之一。它始于1998年，代表了过去11年中大约9,000名受访者收集的大约26,700个数据点。它还使用文献中报道的最贫穷的样本之一：所研究社区的家庭收入中位数（1990年人口普查）为5,190美元，这些社区中有73％的居民生活在贫困水平以下。多年来，MYS从各种来源获得了资金，每个来源都有不同的目标和优先事项。结果，我们的抽样计划并非严格随机，而是使用了一种混合策略，该策略试图从这些社区中采样尽可能多的青少年人群。我们认为样本是代表性的，缺少数据模式是随机的。但是，在MYS数据能够充分发挥其潜力之前，我们必须测试这些假设。因此，这项研究的前两个目的是评估（a）MYS样本的代表性，以及（b）缺失数据的模式，以确定它们是否随机丢失。我们很幸运能够从移动县公立学校系统中获得学校记录，并从移动房屋委员会租赁信息，我们将用来补充这些分析中的MYS数据。第三个目标认为，与没有性，与毒品相关的和/或暴力行为的受访者相比，对从事性，毒品和/或暴力行为的受访者的辍学者是否比没有受访者更高。这是一个重要的问题，它不仅可以帮助我们更好地了解MYS样本，还可以为研究其他高危青少年人群提供有用的信息。公共卫生相关性：过去十年来，在2010年健康人民中发展了许多公共卫生目标，但其他人似乎无视实现目标的努力。可悲的是，其中许多收益使生活在贫困中的人不受欢迎，在城市年轻人中，发病率和死亡率仍然令人难以置信。该项目测试了有关流动青年调查的几个方法论和实质性假设，这是对非常贫穷的非裔美国青少年的11年纵向研究，以确定其适合研究该人群的发展和风险行为的适用性。
