COMMUNITY-BASED PARTICIPATORY RESEARCH

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 自2005年以来，长期目标有两个：1)通过以学校社区为基础的参与性研究方法(CBPR)，通过增加对美国印度和农村学童的体力活动(PA)的参与，对超重/肥胖的发展和风险产生积极影响；以及2)评估互联网传递的PA行为矫正计划对居住在农村社区的中年超重/肥胖成年人的PA水平、心脏代谢疾病风险因素和心理社会/行为变量的有效性。目标1采用CBPR方法，在美国印第安人学区建立和实施了一个基于网络的PA跟踪工具(计步器或时间)。对选定的青年危险行为调查项目和体重指数进行了纵向评估(基于网络的跟踪工具；2006-2008年)，同时实施和发展(持续)以文化/人口为基础的以学校为基础的PA干预措施。基于学校的干预和基于网络的工具已经实施，目前正在第二个较大的农村(主要是高加索人)学校社区使用CBPR方法进行评估。目标2PA和心脏代谢性疾病风险因素有效性测试(随机对照试验；RCT)完成了商业上可获得的、通过互联网传递的、基于理论的体力活动行为改变计划。研究结果显示，在超重/肥胖的成年人中，PA水平和中心性肥胖具有很强的短期预后，但PA在一年内显著复发。对PA行为改变计划进行了循证修订，包括：1)增强互联网互动性和引人入胜的内容；2)逐渐减少干预后的积极干预。一项随机对照试验对互联网提供的PA干预最近实施的循证修改的有效性进行了测试，目前已接近完成(2009年4月)。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Since 2005 the long-term goals have been two-fold: 1) to positively influence the development of and risk for overweight/obesity through increased participation in physical activity (PA) in American Indian and rural schoolchildren using a school community-based participatory research approach (CBPR); and 2) to evaluate the effectiveness of an internet-delivered PA behavior modification program on PA levels, cardiometabolic disease risk factors, and psychosocial/behavioral variables in middle-aged overweight/obese adults residing in rural communities. Goal 1  A CBPR approach was used to build and implement a web-based PA tracking tool (pedometer or time) in an American Indian school district. Select Youth Risk Behavior Survey items and body mass index were evaluated longitudinally (web-based tracking tool; 2006-2008) in conjunction with implementation and development (on-going) of a culture/population specific school-based PA intervention. The school-based intervention and web-based tool were implemented and are currently being evaluated in a second larger rural (predominantly Caucasian) school community using a CBPR approach. Goal 2  PA and cardiometabolic disease risk factor efficacy testing (randomized control trial; RCT) of a commercially available, internet-delivered, theory-based, physical activity behavior change program were completed. Findings demonstrated strong short-term outcomes for PA levels and central adiposity in overweight/obese adults but significant PA relapse occurred at one-year. Evidence-based revisions were made to the PA behavior change program to include: 1) enhanced internet interactivity and engaging content; and 2) tapered post-intervention weaning from the active intervention. A RCT testing the efficacy of these recently implemented evidence-based modifications to the internet-delivered PA intervention is nearly complete (April 2009).
