Longitudinal Effects of Socioeconomic Disadvantage and Racial Discrimination on Health Among African Americans and Puerto Ricans

项目概要/摘要 拟议中的研究将利用以前在关键领域收集的大量纵向数据， 作为哈莱姆纵向发展研究的一部分，它有 两个主要目标：第一个是确定健康的社会决定因素之间的关系的调解人 (i.e.,社会经济不利条件和基于族裔/种族歧视）和非稳态负荷的样本， 非裔美国人和波多黎各人进入中年。该研究建议是由一个上下文指导- 发展模式的基础上，现象变异生态系统理论，以及一个 压力的病理生理学理论（非稳态负荷）。第二，研究将确定差异 从青少年后期到青少年早期， 40岁，检查他们与40岁出头的非稳态负荷和心理健康的关系，并测试他们的能力。 的弹性资源，以减轻这些协会。本研究的样本将由400名男性和 女性非洲裔美国人和波多黎各人谁以前看到在青春期（T1，T2），出现 成年期（T3）、青年期（T4）和成年期（T5、T6）。确定风险和 非稳态负荷运行的保护因素将对公众健康产生重要影响， 干预和通报政策的目标。找到可以减轻有害影响的缓和结构 基于族裔/种族的长期歧视的后遗症将突出显示具有复原力的重要领域。这样的 关注弹性不仅远离了有色人种的赤字观点，而且还具有潜力 转变政策和干预措施，利用优势，而不是处理缺陷。在这方面的一个举动 这一方向是实现消除重大社会和族裔/种族歧视目标的重要一步。 健康差距困扰美国和实现健康公平的所有。

PROJECT SUMMARY/ABSTRACT The proposed research would capitalize on a wealth of longitudinal data previously collected at key developmental stages over a period of 27 years as part of the Harlem Longitudinal Development Study. It has two major aims: The first is to identify the mediators of the relationships between social determinants of health (i.e., socioeconomic disadvantage and ethnicity-based/racial discrimination) and allostatic load in a sample of African Americans and Puerto Ricans entering midlife. The research proposal is guided by a contextual- developmental model based in Phenomenological Variant of Ecological Systems Theory, as well as a pathophysiological theory of stress (allostatic load). Second, the research will identify the differential developmental trajectories of perceived ethnicity-based/racial discrimination from late adolescence to the early forties, examine their associations with allostatic load and mental health in the early forties, and test the ability of resilience resources to mitigate these associations. The sample for this study will consist of 400 male and female African Americans and Puerto Ricans who were previously seen in adolescence (T1, T2), emerging adulthood (T3), young adulthood (T4), and adulthood (T5, T6). Identifying the pathways through which risk and protective factors for allostatic load operate will have important implications for public health by providing targets for intervention and informing policy. Finding moderating constructs that can mitigate the deleterious sequelae of chronic ethnicity-based/racial discrimination will highlight significant areas of resilience. Such a focus on resilience not only moves away from a deficit perspective of people of color, but also has the potential to transform policy and interventions by building on strengths, rather than treating deficits. A move in this direction is an important step towards reaching the goal of eliminating the significant social and ethnic/racial health disparities that plague the U.S. and realizing health equity for all.
