PROJECT SUMMARY Use of public transit has been associated with increased physical activity, and considered a promising approach to reducing the risk of obesity and other age-related chronic conditions such as cancer, diabetes, and heart disease. However, little is known about the physical activity impacts of the increasingly popular Bus Rapid Transit (BRT) which combines the capacity, speed, and reliability of rail transit with the flexibility and cost advantage of a conventional bus system. Further, research is lacking about impacts of transit-oriented multilevel interventions (TOMI) that simultaneously consider multiple synergetic strategies to promote physical activity. This timely natural-experimental study uses a pre-post (opening of new BRT corridors in El Paso, Texas, fall 2018), case- comparison design to examine the causal impact of BRT and other supporting TOMI strategies on residents’ physical activity. The study involves 750 exposed (living within 0.5 miles from a new BRT station) and 500 non-exposed (living beyond 1 mile from any BRT stations) adult participants who live in the city and do not meet weekly physical activity recommendations (150+ minutes of moderate-to-vigorous PA) at baseline. The specific aims of this proposed study are to (1) determine physical activity impacts of BRT; (2) examine physical activity impacts of additional TOMI strategies, including education (lifting the knowledge barrier by offering a smartphone app and training to assist transit trip scheduling and to enhance knowledge about using BRT and BRT-reachable physical activity resources) and cost (lifting the financial barrier to transit use by executing an introductory free-fare strategy); and (3) explore benefits and costs of BRT implementation, and barriers and facilitators of BRT use. There will be three waves of data collection in spring 2018, spring 2019, and spring 2021, respectively. The multidisciplinary team (experts from urban planning, transportation, public health, statistics and disparities research) proposes many innovative policy, theoretical and methodological advances to understand the obesity reduction roles of service-oriented environmental interventions. These include a) conceptualization of multi-level factors influencing and strategies for modifying transit use, b) inclusion of multiple case-comparisons, c) application of relevant methodological approaches more commonly used in other research queries, and d) a citizen science approach for more contextual understanding of the PA-transit relationship. Its strong connection with the local communities and stakeholders and substantial record of research collaboration ensure an effective execution of the proposed research. At the end of the proposed study, the researchers expect to identify the physical activity impact of BRT and other TOMI strategies, examine the benefits and costs of BRT implementation, and reveal barriers and facilitators of BRT use.

项目摘要 公共交通的使用与增加的体育锻炼有关，并被认为是一种有希望的方法 减少肥胖风险和其他与年龄有关的慢性病，​​例如癌症，糖尿病和心脏病。然而， 关于越来越受欢迎的巴士快速运输（BRT）的体育锻炼影响知之甚少 铁路运输的容量，速度和可靠性，具有传统总线系统的灵活性和成本优势。 此外，研究缺乏面向运输的多层次干预措施（TOMI）的影响 考虑多种协同策略来促进体育活动。 这项及时的自然实验研究使用了一个前（得克萨斯州埃尔帕索市的新BRT走廊，2018年秋季），案例 - 比较设计，以检查BRT和其他支持TOMI策略对居民身体的因果影响 活动。该研究涉及750次暴露（居住在新的BRT站0.5英里以内）和500个不暴露（生活） 距离任何BRT电台1英里）的成年参与者，他们居住在城市 基线时的建议（150分钟以上的现代至持久PA）。这项拟议研究的具体目的是 （1）确定BRT的身体活动影响； （2）检查其他TOMI策略的体育活动影响， 包括教育（通过提供智能手机应用程序和培训来协助运输旅行来取消知识障碍 调度并增强有关使用BRT和BRT-RECH-RABL-REACH体育活动资源的知识）和成本（提升） 通过执行简介自由策略来实现过境使用的财务障碍）； （3）探索福利和成本 BRT实施，BRT使用的障碍和促进者。 2018年春季将有三波数据收集， 2019年春季和2021年春季。 多学科团队（城市规划，运输，公共卫生，统计和差异研究的专家） 提出许多创新政策，理论和方法论的进步，以了解肥胖的减少作用 面向服务的环境干预措施。这些包括a）影响多层次因素的概念化和 修改过境使用的策略，b）包含多个病例 - 季节，c）应用相关方法论 其他研究查询中更常用的方法，d）一种公民科学方法，用于更情境 理解PA-Transit关系。它与当地社区和利益相关者以及 研究合作的大量记录可确保对拟议研究的有效执行。在 拟议的研究，研究人员期望确定BRT和其他TOMI策略的体育活动影响，研究 BRT实施的收益和成本，并揭示了BRT使用的障碍和促进者。
