项目摘要

PROJECT SUMMARY/ABSTRACT Cardiovascular disease morbidity and mortality disparities have persisted among African American women despite advances in evidence-based strategies to reduce cardiovascular disease risk factors. African American women often report discrimination-related stress, warranting continued exploration of the mechanisms that link to discrimination to cardiovascular disease. Thus, the long-term research goal is to reduce cardiovascular disease among African American women by elucidating and targeting unique psychophysiological correlates of cardiovascular disease in this population. The overall objective of the pilot project is to examine the overall feasibility of a research protocol to examine associations between discrimination, social cognitive processes, and CVD risk using ecological momentary assessment [EMA] to account for ecological variability and reduce recall bias. The central study hypothesis posits that African American women’s long-term experiences of discrimination contribute to maladaptive schemas and cognitive appraisal that heighten perceived discrimination events. Frequent experiences of discrimination elicit recurrent emotional and physiological stress responses that over time contribute to sustained physiological dysregulation. The study seeks to examine these associations in a sample of 90 African American women aged 18 years and older by accomplishing the following aims: Aim 1. Examine cross-sectional associations between discrimination (e.g., racial, gender), social cognitive processes (e.g., early maladaptive schemas, cognitive appraisal), negative emotion, and sustained physiological dysregulation (allostatic load, telomere length). Aim 2: Examine longitudinal associations (7-days) between discrimination, social cognitive processes, and emotional and physiological reactivity using EMA. The overarching goal of this SC-2 application is to promote the applicant’s long-term NIH research involvement by supporting: a) mentored minority faculty research enhancement and b) training and research productivity in EMA and psychophysiological research methodology. This innovative program of research, building on the applicants’ current training and research expertise, will further elucidate discrimination-related cardiovascular disease risk factors and methodology that accounts for ecological variability among African American women. Findings from this research program have the potential better to inform cardiovascular disease risk prevention strategies among African American women.

项目概要/摘要非裔美国人的心血管疾病发病率和死亡率差异仍然存在非洲妇女在减少心血管疾病危险因素的循证策略方面取得进展。美国女性经常报告与歧视相关的压力，值得继续探索与心血管疾病相关的歧视机制因此，长期研究目标是通过阐明和针对独特的目标来减少非裔美国妇女的心血管疾病该人群心血管疾病的心理生理相关性试点的总体目标。项目的目的是检查研究方案的总体可行性，以检查之间的关联使用生态瞬时评估 [EMA] 来评估歧视、社会认知过程和 CVD 风险解释生态变异性并减少回忆偏差中心研究假设认为非洲。美国女性长期遭受歧视的经历导致了适应不良的模式和认知加剧感知歧视事件的评估。随着时间的推移，情绪和生理压力反应有助于持续的生理反应该研究旨在以 90 名非裔美国女性为样本来检验这些关联。 18 岁及以上，通过实现以下目标：目标 1. 检查横截面协会歧视（例如种族、性别）、社会认知过程（例如早期适应不良模式、认知评估）、负面情绪和持续的生理失调（适应负荷、端粒）目标 2：检查歧视、社会认知过程之间的纵向关联（7 天）。使用 EMA 进行情绪和生理反应该 SC-2 应用程序的总体目标是通过支持以下方式促进申请人长期参与 NIH 研究：a) 受指导的少数族裔教师研究增强和 b) EMA 和心理生理学研究中的培训和研究生产力这项创新的研究计划以申请人当前的培训和研究为基础。专业知识，将进一步阐明与歧视相关的心血管疾病风险因素和方法，该研究项目的结果解释了非洲裔美国妇女的生态变异性。更好地为非裔美国人提供心血管疾病风险预防策略的潜力女性。
