DESCRIPTION (provided by applicant): Mid-life and older African Americans (AAs), a population that is increasing in number, have higher rates of cardiovascular-related morbidity and mortality than Whites, particularly in relation to dietary and physical activity behaviors. Few tested health promotion interventions tailored for mid-life and older AAs are available yet churches have been shown to be an effective environment for AA health programs. Thus, the overall goal of this project is to reduce cardiovascular disease (CVD) risk factors in mid-life and older AAs through implementing and evaluating a church-based health intervention. Using the Transtheoretical Model of Behavior Change (TTM), this project seeks to: 1) determine the effectiveness of a church-based intervention in relation to dietary behaviors (food choice, dietary quality) and habitual physical activity (PA) toward subsequent improvement in CVD risk factors of mid-life and older AAs. Specifically, the intervention will focus on increasing consumption of fruits, vegetables and calcium-rich foods; decreasing consumption of fat, sugar and sodium; increasing habitual PA, all geared to improving selected clinical outcomes (blood lipids, blood pressure, body weight, among others); 2) identify the differentia) influence of program components of the intervention; 3) examine variables that might mediate the process of goal achievement; and 4) determine variables that are related to stage of change progression in goal achievement Midlife and older AAs (n=300) from four churches, two treatment and two comparison, in North Florida will be .selected for the study. The intervention, to be developed using a community-based participatory approach, will include literature-based conceptual elements of awareness building, clinical learning and efficacy development. Instruments will include a food and lifestyle habits questionnaire (food frequency, NCI fruit and vegetable screener, NCI fat screener, physical activity items, TTM items, background characteristics). Cinical data and 3-day dietary records, will be collected from subsample (n=100). Data will be collected at four points: before, 2-times during and after the intervention. The project will be guided by an Advisory Committee (research and community advisors). Diseases such as hypertension and stroke affect mid-life and older African Americans at higher rates than Whites, negatively affecting health status of this group. This project will determine effectiveness of a faith-based intervention to improve health in mid-life and older African Americans.

描述（由申请人提供）：中年和老年非洲裔美国人（AAs）的数量正在增加，其心血管相关发病率和死亡率高于白人，特别是在饮食和体育活动行为方面。很少有专为中年和老年AA量身定制的健康促进干预措施，但教堂已被证明是AA健康项目的有效环境。因此，该项目的总体目标是通过实施和评估基于教会的健康干预来减少中年和老年AAs的心血管疾病（CVD）风险因素。使用行为改变的跨理论模型（TTM），本项目旨在：1)确定以教会为基础的干预与饮食行为（食物选择，饮食质量）和习惯性体育活动（PA）相关的有效性，以改善中年和老年AAs的心血管疾病风险因素。具体来说，干预措施将侧重于增加水果、蔬菜和富含钙的食物的消费；减少脂肪、糖和钠的摄入；增加习惯性PA，所有这些都是为了改善选定的临床结果（血脂、血压、体重等）；2)识别干预方案组成部分的差异影响；3)检验可能中介目标实现过程的变量；4)确定与目标实现的变化阶段进展相关的变量（n=300）来自北佛罗里达州四个教堂的中年和老年aa，两个治疗和两个比较。被选为研究对象。将采用基于社区的参与性方法制定的干预措施将包括建立认识、临床学习和疗效发展等基于文献的概念要素。工具将包括食物和生活习惯问卷（食物频率，NCI水果和蔬菜筛选，NCI脂肪筛选，身体活动项目，TTM项目，背景特征）。从子样本（n=100）中收集临床资料和3天饮食记录。数据将在干预前、干预中、干预后4个时间点采集。该项目将由一个咨询委员会（研究和社区顾问）指导。高血压和中风等疾病在中年和老年非洲裔美国人中的发病率高于白人，对这一群体的健康状况产生了负面影响。该项目将确定以信仰为基础的干预措施在改善中年和老年非裔美国人健康方面的有效性。
