PROJECT SUMMARY AD is the 4th leading cause of death among African Americans and African Americans are two to three times more likely to develop AD compared to non-Hispanic Caucasians. Given the high prevalence of diabetes and obesity and the emerging evidence that up to 50% of AD cases are a result of modifiable risk factors, prevention strategies may play a critical role in reducing AD risk for AAs. Previous research has indicated that adherence to healthy diets such as the Mediterranean diet, Dietary Approaches to Stop Hypertension (DASH), and Mediterranean-DASH Intervention for Neurogenerative Delay (MIND) help slow cognitive decline among adults 65 years and older. However, adherence and acceptability of such diets remain low among African Americans, due to lack of cultural considerations. Thus, there is a critical need for the development of a culturally adapt brain healthy diet that is congruent with African American cultural values and food preferences. Creating a culturally relevant brain healthy diet for African Americans, will enhance both acceptability and adherence which are essential to lifestyle behavioral changes. The proposed project aligns well with the NIA Strategic Directions for Research Goal C-3: Develop interventions for treating, preventing, or mitigating the impact of age-related diseases and condition; by meaningfully incorporating a culturally tailored approach to an adapted diet intervention to reduce the risk of cardiovascular risk factors related to AD and to maintain independence among older African Americans. Specifically, Dr. Shaw plans to address the following specific aims (1) develop an adapted brain healthy soul food diet intervention; (2) pilot test an adapted brain- healthy soul food diet intervention; (3) explore the effect of the adapted brain-healthy soul food diet intervention of cognitive function as preliminary data to design a RCT. To achieve these specific aims, Dr. Shaw will work with a highly skilled mentorship team (Drs. Jeffrey Burns, Debra Sullivan, and Janette Berkley-Patton) and consultants (Dr. Crystal Glover and Mr. Broderick Crawford) to build four areas of expertise relevant to the research agenda: (1) ARDR clinical trial design and implementation (2) cultural tailoring of established diets (3) qualitative design and analysis (4) community-based research design. The K01 award will enhance Dr. Shaw's capabilities to successfully transition into an independent researcher who has expertise in the development and evaluation of culturally tailored lifestyle interventions to reduce AD risk among African Americans. Results of the proposed research will enhance our understanding of how AA culture influences current dietary practice, adherence, acceptability, and feasibility of a brain-healthy diet for older AA. Results will also positively impact the development of R01 scale RCT to test the efficacy of an adapted brain-healthy diet intervention among older AA across a larger geographical area.

项目概要 AD 是非裔美国人的第四大死因，是非裔美国人的两到三倍 与非西班牙裔白种人相比，他们更容易患 AD。鉴于糖尿病的高患病率和 肥胖以及新出现的证据表明，高达 50% 的 AD 病例是由可改变的危险因素造成的， 预防策略可能在降低 AA 的 AD 风险方面发挥关键作用。先前的研究表明 坚持健康饮食，如地中海饮食、预防高血压的饮食方法 (DASH)、 和地中海 DASH 神经生成延迟干预 (MIND) 有助于减缓认知衰退 65 岁及以上的成年人。然而，非洲人对这种饮食的坚持和接受度仍然很低 美国人，由于缺乏文化考虑。因此，迫切需要开发一种 在文化上适应与非裔美国人文化价值观和食物一致的大脑健康饮食 偏好。为非裔美国人创造一种与文化相关的大脑健康饮食，将增强两者 可接受性和坚持性对于生活方式行为改变至关重要。拟议的项目符合 符合 NIA 研究战略方向目标 C-3：制定治疗、预防或治疗的干预措施 减轻与年龄相关的疾病和状况的影响；通过有意义地融入文化定制 采取适应性饮食干预措施以降低与 AD 相关的心血管危险因素的风险 保持年长的非裔美国人的独立性。具体而言，Shaw 博士计划解决以下问题 具体目标 (1) 制定适应大脑健康的灵魂食物饮食干预措施； (2) 对适应的大脑进行试点测试 健康灵魂食物饮食干预； (3)探索适应健脑灵魂食物饮食干预的效果 认知功能作为设计随机对照试验的初步数据。为了实现这些具体目标，肖博士将努力 拥有一支高技能的指导团队（Jeffrey Burns 博士、Debra Sullivan 博士和 Janette Berkley-Patton 博士） 顾问（Crystal Glover 博士和 Broderick Crawford 先生）建立与 研究议程：(1) ARDR 临床试验设计和实施 (2) 既定饮食的文化定制 (3) 定性设计与分析 (4)基于社区的研究设计。 K01奖将增强Shaw博士的 成功转型为具有开发专业知识的独立研究人员的能力 评估根据文化量身定制的生活方式干预措施，以降低非裔美国人的 AD 风险。结果 拟议的研究将增强我们对 AA 文化如何影响当前饮食习惯的理解， 老年 AA 大脑健康饮食的依从性、可接受性和可行性。结果也将产生积极影响 开发 R01 量表随机对照试验，以测试适应的大脑健康饮食干预措施的功效 较旧的 AA 跨越更大的地理区域。
