Promoting Physical Activity in Churchgoing Latinas- LPerez

描述(由申请人提供)：拉美裔成年人中中等到剧烈体力活动(MVPA)的低流行率可能是导致该人群癌症和其他慢性病发病率高的原因之一。目前这项研究的目标主要基于社会生态模型的核心原则，目的是设计、实施和评估一种创新的多层次干预措施，促进去教堂做礼拜的拉丁裔人的身体活动。鉴于教会在拉美裔社区中的核心作用及其对其成员福祉的总体承诺，教堂是本研究的理想环境。以证据为基础的干预将针对活动的三个环境影响(即教堂、教堂周围的邻近社区和社区)以及与MVPA相关的个人因素(即内部/人际、文化和感知的环境变量)。体力活动干预将与针对与癌症预防和控制相关的一般主题的注意力控制条件进行比较。16个教堂将被随机分配到体力活动干预或注意力控制条件下。大约432名每周至少参加教堂礼拜的拉丁裔人将从16个教堂招募为参与者。结果分析将确定多层次干预是否会增加注意控制条件下拉美教徒在干预条件下的MVPA。这项研究的主要结果将包括在实施干预活动后的基线、12个月和24个月用加速计测量的MVPA。将测量内部/人与人之间的调解人和文化调解人，以及环境调解人和主持人，以评估对拉丁裔身体活动的多层次影响。拟议的分组随机对照试验建立在由NCI R21向首席调查员提供资金的形成性和先导性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，推动者实现了个体和环境水平的变化。为了检验对拉丁裔PA的多水平干预的有效性，随机对照试验是对先导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.
