Project Summary. Black Americans in the US fare worse across nearly every health indicator compared to White individuals. In Philadelphia, the location of this study, these health disparities culminate in a stark longevity gap, with average life expectancies in poor, predominantly Black neighborhoods being 20 years lower than in nearby affluent, predominantly White neighborhoods. The fundamental cause of these racial health disparities is structural racism, which operates via interconnected, mutually reinforcing social and economic pathways. Notably, long-standing, systematic disinvestment has resulted in highly segregated Black neighborhoods with dilapidated environmental conditions and severe economic insecurity within Black households, leading to a “feedback loop of concentrated racial disadvantage,” which is strongly tied to poor health. To date, most interventions have focused on individual-level behaviors or single social determinants of health. However, by failing to address the multiple mechanisms that generate persistent health disadvantages for Black Americans, existing interventions have had limited impact. We propose to develop and test a radically different approach in which we intervene on multiple upstream drivers of health in unison to more substantially and durably improve health among Black Americans. This new approach is motivated by the insight that overcoming centuries of structural racism will require significant concentrated investment in the structures that have left Black people and their neighborhoods in peril. Specifically, we will conduct a cluster randomized controlled trial (RCT) of a suite of place-based and financial-wellbeing interventions at the community, organization, and individual/household levels that address the social determinants of racial health disparities. At the community level, we address underinvestment in Black neighborhoods by implementing vacant lot greening, abandoned house remediation, tree planting, and trash cleanup. At the organization level, we partner with community-based financial empowerment providers to develop cross-organizational infrastructure to increase reach and maximize efficiency. At the individual/household levels, we increase access to public benefits, financial counseling and tax preparation services, and emergency cash assistance. We will test this “big push” intervention in 60 Black neighborhoods, with a total of 720 adults. We hypothesize that this “big push” intervention will have significant impact on overall health and wellbeing, blood pressure, psychosocial distress, food insecurity, social connectedness, and violence. This proposal is innovative because when implemented simultaneously in targeted geographic areas, the suite of interventions will address the multiple mechanisms by which structural racism harms Black health. The positive health impacts will be multiplied and longer-lasting what would be achieved by implementing any individual component. The results of the proposed research are expected to have significant public health impact as it will provide timely and scalable evidence of new strategies to more effectively reduce racial disparities in health.

项目摘要。与美国黑人相比，美国黑人在几乎所有健康指标上都表现更差 白人个体。在这项研究的所在地费城，这些健康差距最终以一种 寿命差距，贫困、以黑人为主的社区的平均预期寿命低20岁 比附近富裕、以白人为主的社区要多。这些种族健康的根本原因 不平等是结构性种族主义，它通过相互关联、相辅相成的社会和经济发挥作用 小路。值得注意的是，长期、系统的撤资导致了高度隔离的黑人 黑人地区环境条件破旧、经济严重不安全的社区 家庭，导致了一个“集中种族劣势的反馈循环”，这与穷人密切相关 健康。到目前为止，大多数干预措施都集中在个人层面的行为或单一的社会决定因素上 健康。然而，由于未能解决产生持久健康劣势的多种机制 对于美国黑人来说，现有的干预措施影响有限。我们建议开发和测试一种 截然不同的方法，我们对健康的多个上游驱动因素进行干预 更大幅度、更持久地改善美国黑人的健康状况。这一新方法是有动力的 洞察到，克服数百年的结构性种族主义将需要在以下方面进行大量集中投资 那些让黑人和他们的社区处于危险之中的建筑。具体来说，我们将进行一项 整群随机对照试验(RCT)--一套以地点为基础的财务健康干预措施 社区、组织和个人/家庭层面，解决种族健康的社会决定因素 差距。在社区层面，我们通过实施以下措施解决黑人社区投资不足的问题 空地绿化、废弃房屋整治、植树、垃圾清理。在组织中 在这一层面上，我们与基于社区的金融赋权提供者合作，开发跨组织 基础设施以扩大覆盖范围并最大限度地提高效率。在个人/家庭层面，我们增加了 获得公共福利、财务咨询和纳税准备服务以及紧急现金援助。 我们将在60个黑人社区测试这一“大推动”干预措施，总共有720名成年人。我们假设 这一“大推动”干预措施将对整体健康和福祉、血压、 社会心理困扰、粮食不安全、社会联系和暴力。这个建议很有新意 因为当在目标地理区域同时实施时，一系列干预措施 将解决结构性种族主义损害黑人健康的多种机制。积极的一面 对健康的影响将成倍增加，持续时间将比实施任何个人 组件。拟议的研究结果预计将对公众健康产生重大影响 为更有效地减少健康方面的种族差异的新战略提供及时和可推广的证据。
