Promoting Physical Activity in Churchgoing Latinas- LPerez

描述（由申请人提供）：拉丁裔成年人中高强度体育活动（MVPA）的低患病率可能导致该人群中癌症和其他慢性疾病的高发病率。基于社会生态模型的核心原则，本研究的目的是设计、实施和评估一种创新的多层次干预措施，促进拉丁美洲人的身体活动。鉴于教会在拉丁裔社区中的核心作用及其对其成员福祉的整体承诺，教会是当前研究的理想环境。基于证据的干预将针对三个“层次”的环境影响（即教堂，教堂周围的近邻和社区）对活动的影响，以及与mvpa相关的个人因素（即……）、内部/人际关系、文化和感知环境变量)。身体活动干预将与针对癌症预防和控制的一般主题的注意控制条件进行比较。十六座教堂将被随机分配到体育活动干预组和注意力控制组。将从16个教会招募至少每周参加教会礼拜的大约432名拉丁裔人作为参与者。结果分析将确定多层次干预是否会增加拉丁裔教徒在干预条件下的MVPA相对于注意控制条件。该研究的主要结果将包括在实施干预活动后基线、12个月和24个月的加速度测量MVPA。将测量内部/人际中介因素和文化调节因素，以及环境中介因素和调节因素，以评估对拉丁裔体育活动的多个层面的影响。拟议的小组随机对照试验建立在由NCI R21向首席研究员资助的形成性和试点研究成果以及研究团队20多年的基础工作的基础上。在R21中，发起人实现了个体和环境层面的变化。为了检验多层次干预对拉丁裔PA的有效性，随机对照试验是试点研究的必要和合乎逻辑的后续研究。

DESCRIPTION (provided by applicant): The low prevalence of moderate-to-vigorous physical activity (MVPA) among adult Latinas likely contributes to the high rates of cancer and other chronic diseases in this population. The goals of the current study, based largely upon the core principles of the Social Ecological Model, are to design, implement, and evaluate an innovative multi-level intervention promoting physical activity among churchgoing Latinas. Given the central role of churches within the Latino community and their overall commitment to the well-being of their members, churches serve as the ideal setting for the current study. The evidenced-based intervention will target three "tiers" of environmental influences (i.e., church, immediate neighborhood surrounding the church, and community) on activity, as well as MVPA-related personal factors (i.e.., intra/interpersonal, cultural, and perceived environmental variables). The physical activity intervention will be compared with an attention-control condition targeting general topics related to cancer prevention and control. Sixteen churches will be randomly assigned to either the physical activity intervention or the attention-control condition. Approximately 432 Latinas who attend church services at least weekly will be recruited as participants from the sixteen churches. Outcome analyses will determine whether the multi-level intervention will increase MVPA among Latina churchgoers in the intervention condition relative to the attention-control condition. The study's primary outcome will comprise accelerometry-measured MVPA at baseline, 12 and 24 months following implementation of intervention activities. Intra/interpersonal mediators and cultural moderators, as well as environmental mediators and moderators will be measured to assess multiple levels of influence on Latinas' physical activity. The proposed group - randomized controlled trial builds on formative and pilot research findings funded by an NCI R21 to the Principal Investigator, as well as more than 2 decades of foundational work by the research team. In the R21, the promotoras realized individual and environmental level changes. To examine the effectiveness of the multi-level intervention on Latinas' PA, a randomized controlled trial is an essential and logical follow-up to the pilot study.
