DESCRIPTION (provided by applicant): The overall goal of this project is to expand on the evaluation of an ongoing NIH grant "Improving Safety and Access for Physical Activity" (Positive Action for Today's Health (PATH): R01 DK067615). Specifically this supplemental project will add trail observations and spatial analyses to enhance our understanding of how the PATH interventions may work. Two communities in the PATH trial have been randomized to receive a social marketing plus police patrolled-walking program or a police patrolled walking only intervention. We have developed protocols for conducting systematic trail use observations and audits of the physical trail-related environment and have developed additional individual level measures of related social environmental factors (community connectedness, collective efficacy, social networks, social support) for this supplemental project. Internal bridge funds have been provided by the South Carolina Research Nutrition Consortium to allow us to conduct baseline assessments of these measures prior to beginning the PATH interventions. This proposed supplement project would support the 12-month, 18-month and 24-month trail observations which will provide a second primary outcome for PATH as well as enhance our understanding of how the social marketing intervention is related to improvements in social factors, moderate physical activity (MPA) and trail use over the 24-month intervention. A total of 260 (130 per community) participants will be the focus of this supplement grant (219 recruited to date). The primary aims of the supplemental project will be to examine 1) trail use in the social marketing plus police patrolled walking vs. police patrolled-walking only communities, 2) how, household proximity to the walking trails and residential clustering of trail use are associated with individual level social environmental variables, and 3) how changes in MPA and trail use are mediated by improvements in individual level social factors in social marketing intervention participants from baseline to 12-months, 18-months and 24-months. PUBLIC HEALTH RELEVANCE: The benefits of the proposed research will include increasing our understanding about how social marketing, proximity to the walking trails, and clustering of higher trail use in certain residential areas relates to changes in the social and physical environmental eterminants of physical activity and trail use in low-income, high violent communities. Understanding the social and physical environmental mechanisms in promoting physical activity in underserved communities will ultimately reduce the rate of obesity, chronic disease, and health care costs in the United States.

描述（由申请人提供）：该项目的总体目标是扩大对 NIH 正在进行的拨款“提高身体活动的安全性和便利性”的评估（积极行动促进当今健康 (PATH)：R01 DK067615）。具体来说，这个补充项目将添加踪迹观察和空间分析，以增强我们对 PATH 干预措施如何发挥作用的理解。 PATH 试验中的两个社区被随机分配接受社会营销加警察巡逻步行计划或警察巡逻步行干预计划。我们制定了用于对与实际步道相关的环境进行系统步道使用观察和审计的协议，并为此补充项目制定了相关社会环境因素（社区连通性、集体效能、社交网络、社会支持）的额外个人层面的衡量标准。南卡罗来纳州研究营养联盟提供了内部过桥资金，使我们能够在开始 PATH 干预之前对这些措施进行基线评估。这 拟议的补充项目将支持 12 个月、18 个月和 24 个月的试验观察，这将为 PATH 提供第二个主要结果，并增强我们对社会营销干预如何与 24 个月干预期间社会因素、适度体力活动 (MPA) 和试验使用的改善相关的理解。总共 260 名（每个社区 130 名）参与者将成为这笔补充赠款的重点（迄今为止已招募 219 名）。补充项目的主要目标是检查 1) 社会营销中的步道使用加上警察巡逻的步行与仅警察巡逻的步行社区的比较，2) 家庭与步行道的接近度和步道使用的住宅集群如何与个人层面的社会环境变量相关联，以及 3) 从基线到 12 个月，MPA 和步道使用的变化如何通过社会营销干预参与者的个人层面的社会因素的改善来调节， 18个月和24个月。公共卫生相关性：拟议研究的好处将包括增加我们对社会营销、步行道的邻近性以及某些住宅区较高步道使用的聚集如何与低收入、高暴力社区中体力活动和步道使用的社会和物理环境决定因素的变化相关的理解。了解在服务不足的社区促进身体活动的社会和物理环境机制将最终降低美国的肥胖率、慢性病和医疗保健费用。
