DESCRIPTION (Adapted from the Applicant's Abstract): The cardiovascular (C-V) system is one of the organ systems most affected by the aging process. Significant differences in C-V morbidity and mortality occur by race and gender that influence longevity. The proposed research involves a biracial (black-white) population that has been followed for C-V risk factors and lifestyles in the Bogalusa Heart Study over the past 25 years. The specific aim of the research is to characterize traits (intrinsic aging vs. The risk factor burden) in a population reaching middle age that influence the subclinical C-V disease process in normal aging. The extensive data base collected since childhood provides information related to silent underlying C-V disease and aging. The study cohort includes 1,200 individuals born between 1959 and 1969, who were examined at least four times since childhood. The cohort will be examined for: 1) C-V risk factor variables comprising obesity measures, blood pressure, lipids, lipoproteins, apoliproproteins, homocysteine, glucose, insulin, fibrinogen, plasminogen activator inhibitor 1, intercellular adhesion molecules -1, C-reactive protein, lipid peroxides and microalbuminuria; 2) lifestyle and psychosocial variables such as tobacco and alcohol use, physical activity, diet, and life change events; 3) subclinical changes of the heart and vasculature (outcome variables) observed by echo-Doppler measurements of cardiac-carotid structure and function and brachial and radial artery compliance; and 4) selected longevity-associated allele markers, like apoE. These variables (except for the allele markers) will be measured at two points in time, with a 3-year interval. In addition, a family history of longevity and health history information on study subjects and their parents and grandparents will be obtained to evaluate familial risk characteristics of the cohort. The proposed studies will provide insights into the interaction of normal aging and predisposing factors that influence the subclinical C-V disease process in a black-white population reaching middle age. Understanding the evolution of C-V risk in normal aging can lead to more rational programs for successful aging and longevity and C-V disease prevention.

描述（改编自申请人摘要）：心血管（C-V） 系统是受衰老过程影响最大的器官系统之一。 不同种族和性别的C-V发病率和死亡率存在显著差异 影响寿命的因素。拟议的研究涉及一项生物技术， （黑人-白人）人群中的C-V风险因素， 在过去的25年里，博加卢萨心脏研究中的生活方式。具体目标 这项研究的目的是描述特征（内在衰老与风险因素 负担），影响亚临床C-V 正常衰老过程中的疾病。从那时起收集的大量数据库 儿童期提供了与无症状的潜在C-V疾病相关的信息， 衰老研究队列包括1959年至1969年出生的1,200人， 从童年起至少被检查过四次则将队列 检查：1）C-V风险因素变量，包括肥胖测量，血液 压力，脂质，脂蛋白，载脂蛋白，同型半胱氨酸，葡萄糖， 胰岛素，纤维蛋白原，纤溶酶原激活物抑制剂1，细胞间粘附 分子-1、C-反应蛋白、脂质过氧化物和微量白蛋白尿; 2） 生活方式和心理社会变量，如吸烟和饮酒，身体 活动、饮食和生活变化事件; 3）心脏的亚临床变化， 通过回声多普勒测量观察到的血管（结局变量） 心脏-颈动脉结构和功能以及肱动脉和桡动脉 依从性;和4）选择的长寿相关等位基因标记，如apoE。 这些变量（等位基因标记物除外）将在两个点进行测量 时间上，间隔3年。此外，家族长寿史和 研究受试者及其父母和祖父母的健康史信息 以评估队列的家族风险特征。的 拟议的研究将提供对正常衰老和 诱发因素，影响亚临床C-V疾病的过程中， 黑人白人达到中年。了解C-V的演变 正常衰老的风险可以导致更合理的成功衰老计划 以及预防心脑血管疾病的能力。
