DESCRIPTION (provided by applicant): Physical activity (PA) has been shown to decrease the risk of chronic disease outcomes that affect a large proportion of the African American community. Despite known benefits, PA is low among African American women. Additional work is needed to identify successful strategies for increasing and maintaining participation in PA, particularly among populations with the highest prevalence of poor health outcomes associated with non- or low participation in health-related behaviors. Churches are central in the African American community for spiritual guidance as well as a source of communication, social support, and networking and are recognized as an ideal setting for health education and health promotion efforts. Several studies have been conducted within churches to increase physical activity levels among African Americans and have shown promise for promoting health behaviors. However, the specific mechanisms by which tenets of faith operate to impact constructs within established behavior change theories have not been adequately elucidated. In addition, it is not clear whether a faith-based intervention is more appropriate than other strategies for maintaining changes in behavior after an intensive intervention. The goal for the proposed study is to determine the impact of strategies for increasing and maintaining levels of PA in church settings. Sedentary African American women (> 18 years), with no risk factors for adverse outcomes associated with increasing daily PA, will be recruited and randomized to one of three conditions-a faith-based intervention, a non-faith-based intervention, or a control. We will recruit 480 participants from 24 churches. Randomization to intervention conditions will occur at the church level. Both active interventions will include 24 group-based sessions, which will begin with weekly sessions (n = 16 sessions), and then phase to less frequent contact with bi-weekly sessions (n = 4 sessions) and monthly sessions (n = 4 sessions). Participants in the control group will receive standard educational material encouraging participation in daily physical activity. Follow-up data will be measured immediately after the 24 sessions and one year after randomization to determine immediate and sustained changes in PA behaviors. The primary outcome of interest is change in steps/day. Secondary outcomes of interest include daily moderate-to-vigorous PA, meeting national PA recommendations, body mass index, and health-related quality of life. For outcomes of interest, we will compare the effect of the active intervention with the control group. We expect treatment effects to emerge such that assignment to either of the active interventions is associated with greater changes in outcomes of interest compared to the control group. We will also evaluate the mechanisms by which a faith-based intervention impacts constructs in the proposed conceptual model to promote increases in daily physical activity, and we further hypothesize that changes in the faith-based intervention group will be greater than changes in the non-faith-based intervention group. PUBLIC HEALTH RELEVANCE: This project is relevant because it addresses a significant public health issue-increasing physical activity levels among African American women in community-based and culturally relevant settings, a segment of the population most in need of interventions focused on decreasing risk factors associated with chronic disease. If successful, the proposed project will add to existing literature by describing an approach that is successful for initiating and sustaining change in a behavior that is a risk factor for various health outcomes associated with low levels of physical activity.

描述（由申请人提供）：已显示体育活动（PA）降低了影响非裔美国人社区很大一部分的慢性疾病结果的风险。尽管有已知的好处，但PA在非裔美国妇女中还是很低。需要额外的工作来确定增加和维持PA参与的成功策略，尤其是在与健康相关行为的不良健康结果较差的人群中最高的人群中。教会是非裔美国人社区的核心精神指导，社会支持和网络的来源，被认为是健康教育和健康促进工作的理想环境。在教堂内进行了几项研究，以提高非洲裔美国人的体育活动水平，并显示出促进健康行为的希望。但是，信仰宗旨会影响既定行为改变理论中建构的特定机制尚未得到充分阐明。此外，尚不清楚基于信仰的干预措施是否比其他策略更合适，以维持强化干预后行为变化。拟议的研究的目标是确定在教会环境中提高和维持PA水平的策略的影响。久坐的非洲裔美国妇女（> 18岁），没有与每日PA的不良后果相关的危险因素，将被招募并随机分配到三种条件之一 - 基于信仰的干预措施，基于非信仰的干预措施或控制。我们将招募来自24个教堂的480名参与者。随机分配给干预条件将在教会层面发生。两种主动干预措施都将包括24个基于小组的会话，该会议将从每周的会议开始（n = 16个会话），然后阶段与每两周一次的会话（n = 4个会话）和每月的会话（n = 4个会话）较少接触。对照组的参与者将获得标准的教育材料，以鼓励参与日常体育锻炼。随访后，将立即测量随访数据，然后在随机分组后一年，以确定PA行为的立即和持续变化。感兴趣的主要结果是步骤/天的变化。感兴趣的次要结果包括每日中度至剧烈的PA，满足国家PA的建议，体重指数和与健康相关的生活质量。对于感兴趣的结果，我们将将主动干预措施的效果与对照组进行比较。我们预计将出现治疗效果，以便与对照组相比，分配给任何一个主动干预措施都与感兴趣结果的更改有关。我们还将评估基于信仰的干预措施在拟议的概念模型中影响构建体以促进日常体育锻炼的增加的机制，我们进一步假设基于信仰的干预组的变化将大于基于非信仰的干预组的变化。公共卫生相关性：该项目具有相关性，因为它解决了在基于社区和文化有关的环境中，非洲裔美国妇女的体育锻炼水平的重大问题，这是最需要干预措施的人群中的一部分，这些干预措施侧重于减少与慢性病相关的危险因素。如果成功的话，拟议的项目将通过描述一种成功启动和维持行为变化的方法来增加现有文献，这是与低水平的体育活动相关的各种健康结果的危险因素。
