Project Summary/Abstract The Georgetown and South Park communities of the Duwamish Valley (DV) face higher levels of environmental pollution and poorer health outcomes compared to the rest of Seattle. For many years the communities have organized to address these environmental and health disparities, prioritizing air pollution and asthma. Our proposal is (1) directly responsive to community requests, (2) strengthens previous community-academic-government partnerships in the DV, (3) advances the environmental health interests of the community, (4) investigates low-cost tools for the measurement and control of air pollution, and (5) evaluates individual and community empowerment throughout all phases of research and action. This multilevel community engaged research (CEnR) project proposes elements that will engage and empower members of the DV community. The household-level intervention - providing participants with indoor air filters - has the goal of improving indoor air quality and reducing asthma symptoms in children. In contrast with previous studies investigating high-efficiency particulate air (HEPA) filtration, our intervention will evaluate the effectiveness of low-cost box fans equipped with lower-efficiency filters with greater airflow. The low-cost filters will be coupled with established home-based multicomponent, multi-trigger indoor air quality assessment of homes. We will conduct a randomized control trial to rigorously evaluate differences between intervention and control households in asthma outcomes such as symptoms and forced expiratory volume and in concentrations of indoor particulate matter (PM) and black carbon (BC). Promotores and healthy home consultants recruited from the community will be instrumental in carrying out the intervention. At the community level, we will expand community-driven ambient air monitoring campaigns, prioritizing the characterization of traffic-related air pollution, identification of pollutant sources, and emissions reductions. The use of a low-cost monitoring network will improve the spatial resolution of air quality data in the DV, enabling us to identify PM, BC and nitrogen dioxide hotspots. Youth from the well-established Duwamish Valley Youth Corp program will be trained in various aspects of air monitoring to help carry out the campaign. Armed with data on air quality, community members (who will also be trained in policy advocacy) can advocate for structural change including policy, infrastructure improvements such as urban green space, and targeted regulation of industrial and/or transportation emissions. Throughout the project, independent evaluation of individual and community engagement and empowerment will be tracked. From defining scientific goals, to project implementation and evaluation, our CEnR approach is designed to engage and empower a resilient community in its goal to advance health equity.

项目总结/摘要 Duwamish山谷（DV）的乔治敦和南方公园社区面临着更高水平的 与西雅图的其他地方相比，环境污染和健康状况较差。多年来 社区已经组织起来解决这些环境和健康方面的差异， 和哮喘。我们的建议是（1）直接响应社区的要求，（2）加强以前的 社区-学术-政府在DV中的伙伴关系，（3）促进环境健康利益， 社区，（4）调查用于测量和控制空气污染的低成本工具，以及（5） 在研究和行动的所有阶段评估个人和社区赋权。这 多层次社区参与研究（CEnR）项目提出了参与和授权的要素 DV社区的成员。家庭一级的干预-为参与者提供室内空气过滤器- 目的是改善室内空气质量，减少儿童哮喘症状。相比 以前的研究调查高效微粒空气（HEPA）过滤，我们的干预将评估 低成本箱式风扇配备了效率较低的过滤器，具有更大的气流效率。低成本过滤器 将与已建立的以家庭为基础的多组分，多触发室内空气质量评估相结合， 木屋.我们将进行一项随机对照试验，以严格评估干预和 控制家庭的哮喘结果，如症状和用力呼气量， 室内颗粒物（PM）和黑碳（BC）的浓度。促销员和健康的家 从社区招聘的顾问将有助于开展干预工作。在社区 我们将扩大社区驱动的环境空气监测活动，优先确定 与交通有关的空气污染、确定污染源和减少排放。使用低成本 监测网络将提高DV中空气质量数据的空间分辨率，使我们能够识别PM， BC和二氧化氮热点。来自成熟的Duwamish Valley Youth Corp计划的青年将 接受空气质素监察各方面的训练，以协助推行运动。有了空气质量数据， 社区成员（他们也将接受政策宣传方面的培训）可以倡导结构改革，包括 政策、城市绿色空间等基础设施的改善，以及对工业和/或 交通排放。在整个项目中，对个人和社区的独立评估 将跟踪参与和赋权情况。从确定科学目标，到项目实施， 评估，我们的CEnR方法旨在参与并赋予弹性社区以实现其目标， 促进健康公平。
