Project Summary Cancer disparities impacting African Americans are deeply rooted in historical social injustices such as structural racism, housing discrimination and redlining, struggling educational systems, and concentrated poverty. It is well-established that the neighborhood where a person lives can have a considerable impact on their health and health behaviors. This includes cancer control behaviors, a primary driver of cancer incidence and mortality. Our preliminary data suggests that neighborhood characteristics contribute uniquely to cancer control behaviors beyond individual factors in African Americans. However, little is known about multi-level and longitudinal influences of structural racism and discrimination in predicting cancer control behaviors, and the potential role of protective psychosocial resources. This is particularly true among African Americans, who suffer a disproportionate cancer burden. The proposed study will quantitatively measure SRD, evaluate its longitudinal role in cancer control behaviors, and examine the moderating role of psychosocial resources in African American adults. In Aim 1, we will construct an index of structural racism and discrimination from publicly available data for use in the Aims 2 and 3 analysis. In Aim 2, we will evaluate the relative contributions of the impact of historical, long-term, and current place-based exposure to structural racism and discrimination on cancer control behaviors (e.g., diet, smoking, physical activity, screening) in probability samples of African Americans from four focal states (N=5000) via a multilevel analysis. In Aim 3, we will test the moderating role of psychosocial resources in the relationship between exposure to SRD and cancer control behaviors in African Americans. Study findings will have important implications for policy and community interventions to eliminate persistent cancer disparities that disproportionately impact African Americans.

项目摘要 影响非洲裔美国人的癌症差异深深植根于历史社会不公正上，例如 结构性种族主义，住房歧视和红线，挣扎的教育系统和集中 贫困。公认的是，一个人居住的社区会对 他们的健康和健康行为。这包括癌症控制行为，这是癌症发病率的主要驱动力 和死亡率。我们的初步数据表明，邻里特征对癌症有独特的贡献 在非洲裔美国人中的个人因素之外的控制行为。但是，关于多层次和 结构性种族主义和歧视在预测癌症控制行为中的纵向影响，以及 保护性社会心理资源的潜在作用。在非裔美国人中尤其如此 承受不成比例的癌症负担。拟议的研究将定量测量SRD，评估其 在癌症控制行为中的纵向作用，并检查社会心理资源在 非裔美国人成年人。在AIM 1中，我们将建立一个结构性种族主义和歧视的指数 可在目标2和3分析中使用的公共可用数据。在AIM 2中，我们将评估相对贡献 历史，长期和当前基于地点的结构性种族主义和歧视的影响 关于癌症控制行为（例如，饮食，吸烟，体育锻炼，筛查） 来自四个重点状态的美国人（n = 5000）通过多级分析。在AIM 3中，我们将测试调节角色 在暴露于SRD与癌症控制行为之间的关系中的社会心理资源 非裔美国人。研究结果将对政策和社区干预具有重要意义 消除对非裔美国人影响不成比例的持续性癌症差异。
