描述(由申请者提供)：通过改善营养和增加体力活动来减少肥胖是疾控中心可赢之战倡议的目标之一。减少农村居民的肥胖尤为重要，因为他们比城市居民更有可能肥胖。事实上，在50个州中，爱荷华州居民的肥胖率排名第33位，爱荷华州有一半的成年人不符合PA的建议。由于大多数循证干预措施都是在城市或郊区测试过的，因此在农村小城镇(50,000名居民)中增加公共卫生的有效干预措施很少。在中西部，这些小城市社区也是拉美裔人口涌入的“新目的地”。农村健康预防研究中心(PRC-RH)以肥胖为重点，通过各种中心活动和资源以及实施干预研究项目ActiveOtumwa来应对爱荷华州小镇和其他农村社区居民的健康挑战。PRC-RH中心的活动包括维护以社区参与为核心的基础设施，交流和传播PRC-RH研究和最佳实践，培训公共卫生专业人员、学生和社区成员，以及评估PRC-RH活动。PRC-RH与爱荷华州公共卫生部建立了充满活力的合作伙伴关系，这是一个积极的社区咨询委员会，在爱荷华州的渥太华拥有当地卫生部门和社区组织的代表，这是一个微型的新目的地社区。PRC-RH干预研究项目Active Otumwa专注于通过确定基于社区的PA干预的有效性，该干预使用非专业健康顾问(LHA)方法来实施循证PA策略，从而增加渥太华的体力活动。根据《社区指南》的现有证据和战略，活跃的渥太华将在三个影响层面上开展活动：1)社区范围的运动(例如报纸、电视和广播公告、网站曝光和公共卫生教育计划)；2)行为和社会支持干预(例如行为合同、伙伴系统、目标设定，以促进和支持PA活动；3)土地使用政策和PA获得场所的机会，(例如。与当地政府官员、机构和社区领袖合作，倡导、改善和创造进入和使用PA设施的机会)。为了评估活跃的渥太华，将使用混合方法，包括全社区调查；对一群居民进行纵向跟踪，完成加速测量、身体和人体测量以及调查数据；观察性措施；关键线人深度访谈；以及项目文件。该研究项目和PRC-RH将通过调整在城市和郊区测试的干预策略来解决我们PA知识中的一个主要证据缺口，以适应农村州的微型新目的地社区。

DESCRIPTION (provided by applicant): Reducing obesity, through improved nutrition and increased physical activity is one of the goals of the CDC's Winnable Battles initiative. Reducing obesity in rural residents is especially important since they are more likely to be obese than urban residents. Indeed, Iowa residents rank 33rd of 50 states in the percent of residents who are obese and half of Iowa's adults do not meet PA recommendations. Effective interventions to increase PA in rural micropolitan (<50,000 residents) communities are scant since most evidence-based interventions have been tested in urban or suburban areas. In the Midwest, these micropolitan communities are also "new destination" locations for an influx of Latino populations. The Prevention Research Center for Rural Health (PRC-RH), with a focus on obesity, addresses the health challenges of residents of micropolitan and other rural communities in Iowa through a variety of Center activities and resources as well as the implementation of an intervention research project, ActiveOttumwa. PRC-RH Center activities include maintenance of an infrastructure with cores focusing on community engagement, communication and dissemination of PRC-RH research and best practices, training of public health professionals, students and community members, and evaluation of PRC-RH activities. The PRC-RH has vibrant partnerships with the Iowa Department of Public Health, an active Community Advisory Board, with local health department and community organization representation, in Ottumwa, Iowa, a micropolitan new destination community. The PRC-RH intervention research project, Active Ottumwa focuses on increasing physical activity in Ottumwa by determining the effectiveness of a community-based PA intervention that uses a lay health advisor (LHA) approach - to implement evidence-based PA strategies. Based on the available evidence and strategies from the Community Guide, the Active Ottumwa will implement activities at three levels of influence: 1) community-wide campaigns (e.g. newspaper, TV, and radio announcements, website exposure and public health education programs; 2) behavioral and social support interventions (e.g. behavioral contracts, buddy systems, goal-setting to promote and support PA activities; and 3) land-use policies and access to places for PA, (.e.g. working with local governmental officials and agencies and community leaders to advocate, improve and create opportunities for access and use of facilities for PA). To evaluate Active Ottumwa, mixed methods will be used including a community-wide survey; longitudinal follow up of a cohort of residents that will complete accelerometry, physical and anthropometric measures and survey data; observational measures; key informant in-depth interviews; and project documentation. The research project and PRC-RH will address a major evidence gap in our PA knowledge by adapting intervention strategies tested in urban and suburban areas to a micropolitan new destination community in a rural state.
