PROJECT SUMMARY Racial/ethnic minorities are at a higher risk for age-related cognitive dysfunction compared to non-Hispanic (NH) Whites. The mechanisms underlying this disparity are not well understood. Exposure to air pollution may be one important driver of these disparities. Recent epidemiologic studies suggest that increased exposure to air pollution increases risk of Alzheimer’s disease and related dementias (ADRD). Compared to NH Whites, racial/ethnic minorities are more likely to live in neighborhoods with higher levels of air pollution. No prior research, however, has quantified the contribution of air pollution as a driver of racial/ethnic disparities in ADRD. The scientific objective of this research is to evaluate air pollution as a potential driver of racial/ethnic disparities in ADRD and to understand the potential implications of air quality regulations on ADRD risk. We will focus this research on disparities between Mexican American and NH White racial/ethnic groups. This project uses an innovative approach to combine data from two existing cohort studies: The Sacramento Area Latino Study on Aging and the Ginkgo Evaluation of Memory Study. We will harmonize outcome and exposure data from the two cohorts and examine whether the effect of air pollution on ADRD risk varies across racial/ethnic groups. We will also examine whether air pollution drives disparities in ADRD by examining racial/ethnic differences in air pollution exposure, individual- and neighborhood-level susceptibility to air pollution. Finally, we will measure the potential impacts of air quality regulations on ADRD risk, using air quality regulations related to seaports as an example. The proposed research will leverage advanced causal inference methods including econometric quasi-experimental study designs to carry out the proposed research. This research plan is complemented by a mentored training plan that builds upon the candidate’s background in environmental epidemiology and includes coursework, structured mentoring, and experiential learning in the following areas: 1) racial/ethnic disparities in ADRD, 2) environmental health disparities, 3) harmonization of cognitive data, 4) air quality regulations, and 5) application of advanced social epidemiology and causal inference methods. Together, the proposed research and training plan will prepare the candidate for a successful independent research career dedicated to identifying environmental determinants of healthy aging, especially in racial/ethnic minority populations.

项目摘要 与非西班牙裔相比 （NH）白人。这种差异的基础机制尚不清楚。暴露于空气污染可能 成为这些分布的重要驱动力。最近的流行病学研究表明，对 空气污染增加了阿尔茨海默氏病和相关痴呆症（ADRD）的风险。与NH白人相比 种族/族裔少数民族更有可能生活在空气污染水平较高的社区中。没有先验 但是，研究已量化了空气污染作为种族/种族差异驱动力的贡献 adrd。这项研究的科学目的是评估空气污染，作为种族/族裔的潜在驱动力 ADRD的差异，并了解空气质量法规对ADRD风险的潜在影响。我们 将把这项研究集中在墨西哥裔美国人和NH白人种族/族裔群体之间的差异上。这 项目使用一种创新的方法来结合两项现有队列研究的数据：萨克拉曼多地区 拉丁美洲人对衰老和银杏记忆研究评估的研究。我们将协调结果和暴露 来自两个队列的数据和检查空气污染对ADRD风险变化的影响是否跨越 种族/族裔。我们还将检查空气污染是否通过检查ADRD的分布 空气污染的种族/种族差异，个人和邻里水平的空气敏感性 污染。最后，我们将使用空气质量来衡量空气质量法规对ADRD风险的潜在影响 与海港有关的法规为例。拟议的研究将利用高级因果推断 包括经济准实验研究的方法设计了拟议的研究。这 研究计划是由心理培训计划完成的，该计划以候选人的背景为基础 环境流行病学，包括课程，结构化的心理和经验丰富的学习 以下领域：1）ADRD中的种族/种族差异，2）环境健康差异，3）协调 认知数据，4）空气质量法规，以及5）应用高级社会流行病学和因果 推理方法。拟议的研究和培训计划一起将为候选人做好准备 成功的独立研究职业，致力于确定健康衰老的环境决定者， 特别是在种族/族裔少数民族中。
