Advancing Environmental Justice in the Community Using Charrette: A Case Study in Boston Chinatown.

Background: Community research partners in Boston Chinatown implemented a planning charrette as a part of a community-based participatory study focused on near highway research and public health action to mitigate traffic-related air pollution (TRAP). Charrettes are intensive workshops for solution-oriented design and planning used to bring together diverse stakeholders to address complex environmental health concerns. Methods: The planning charrette included three phases: (1) community meetings and resident interviews, (2) a planning charrette to address community health concerns and air pollution within larger community wellness goals, and (3) development of a Master Planning document with policy, project, and practice recommendations to guide future community advocacy. Outcomes: Intergenerational residents, community leaders, planners, researchers, and volunteers (N = 90) joined a day-long planning charrette to inform the Chinatown Master Plan. Workshops were informed by resident interviews focused on finding solutions to three resident identified priorities: Healthy Housing, Healthy Mobility, and Healthy Public Realm. Air pollution mitigation strategies were embedded in discussions around each priority area. Discussion: The charrette provided an opportunity for community stakeholders to voice concerns about TRAP as part of a new framework focused on health and wellness. Concerns about pedestrian safety, housing access, and expansion of green and recreational spaces were highlighted by participants as important areas for further development. Conclusions: Boston Chinatown residents reaffirmed their investment in the community by highlighting concerns about TRAP within the context of other health-related concerns. Charrettes offer a vehicle to advance environmental justice in communities through collective problem-solving and decision making.

Adapting an In-Home Randomized Intervention Trial Protocol for COVID-19 Precautions.

BACKGROUND: The COVID-19 pandemic has significantly impacted the status of clinical trials in the United States, requiring researchers to reconsider their approach to research studies. In light of this, we discuss the changes we made to the protocol of the Home Air Filtration for Traffic-Related Air Pollution (HAFTRAP) study, a randomized crossover trial of air filtration in homes next to a major highway. The senior authors designed the trial prior to the pandemic and included in-person data collection in participants' homes. Because of the pandemic, we delayed the start of our trial in order to revise our study protocol to ensure the health and well-being of participants and staff during home visits. To our knowledge, there have been few reports of attempts to continue in-home research during the pandemic. METHODS: When pandemic-related protective measures were imposed in March 2020, we were close to launching our trial. Instead, we postponed recruitment, set a new goal of starting in September 2020, and spent the summer of 2020 revising our protocol by developing increased safety precautions. We reviewed alternative approaches to installing portable air filtration units in study participants' homes, in order to reduce or eliminate entry into homes. We also developed a COVID-19 safety plan that covered precautionary measures taken to protect both field team staff and study participants. RESULTS: Our primary approach was to minimize contact with participants when collecting the following measures in their homes: (1) placing portable air filtration units; (2) conducting indoor air quality monitoring; (3) obtaining blood samples and blood pressure measurements; and (4) administering screening, consent, and follow-up questionnaires that coincided with collection of biological measures. Adapting our public health trial resulted in delays, but also helped ensure ethical and safe research practices. Perceived risk of COVID-19 infection appeared to have been the primary factor for an individual in deciding whether or not to participate in our trial, particularly at the beginning of the pandemic, when less was known about COVID-19. CONCLUSIONS: We needed to be flexible, creative, and calm when collaborating with community members, the IRB, and the universities, while repeatedly adjusting to changing guidelines as we determined what worked and what did not for in-home data collection. We learned that high-quality air monitoring data could be collected with minimal in-person contact and without compromising the integrity of the trial. Furthermore, we were able to collect blood pressure and phlebotomy data with minimal risk to the participant.

An Evaluation of an Environmental Health Infographic in Community Settings.

Background: Infographics are an effective way of communicating complex information due to their reliance on concise language and clear, uncluttered visuals. Research indicates that traffic-related ultrafine particles (UFPs) in air pollutions adversely affect human health, including respiratory and cardiovascular diseases. In this study, we work with community-based adult literacy programs to develop an infographic about UFPs in air pollution with the goal of community-driven problem solving related to traffic-related UFPs within affected neighborhoods. Objective: In this paper, we discuss the development and evaluation of an infographic about the dangers of UFPs from traffic pollution, and actions that readers in affected communities can take to protect their health. We used the infographic format to conceptualize UFP pollution and its health effects visually for community members many of whom are new immigrants and do not speak English as their first language. Methods: We conducted 1 focus group and 4 interviews over Zoom, and collected 74 anonymous surveys among Boston Chinatown and Somerville, MA residents. Community partner organizations assisted us in recruiting participants by sending a recruitment flyer to their email contacts and identifying specific people who were interested in participating. Key Results: Data from the surveys, focus group, and interviews yielded 8 themes that guided the revision of the infographic. The majority of the participants responded positively to the infographic: 95.9% (n = 71) of respondents reported that the purpose of the infographic was clear, that the infographic contained a clear message, and that the infographic uses images to explain important points. Conclusions: Our experience developing and evaluating an infographic about near highway pollution in environmental justice communities suggests that infographics can be a viable communication tool in this context. Further research with infographics of a similar nature but in diverse communities is needed to strengthen our conclusion.

A randomized crossover trial of HEPA air filtration to reduce cardiovascular risk for near highway residents: Methods and approach.

BACKGROUND: Near highway residents are exposed to elevated levels of traffic-related air pollution (TRAP), including ultrafine particles, which are associated with adverse health effects. The efficacy of using in-home air filtration units that reduce exposure and potentially yield health benefits has not been tested in a randomized controlled trial. METHODS: We will conduct a randomized double-blind crossover trial of portable air filtration units for 200 adults 30 years and older who live in near-highway homes in Somerville, MA, USA. We will recruit participants from 172 households. The intervention periods will be one month of true or sham filtration, followed by a one-month wash out period and then a month of the alternate intervention. The primary health outcome will be systolic blood pressure (BP); secondary outcome measures will include diastolic and central BP, C-Reactive Protein (CRP) and D-dimer. Reasons for success or failure of the intervention will be evaluated in a subset of homes using indoor/outdoor monitoring for particulate pollution, personal monitoring, size and composition of particulate pollution, tracking of time spent in the room with the filter, and interviews for qualitative feedback. RESULTS: This trial has begun recruitment and is expected to take 2-3 years to be completed. Recruitment has been particularly challenging because of additional precautions required by the COVID-19 pandemic. DISCUSSION: This study has the potential to shed light on the value of using portable air filtration in homes close to highways to reduce exposure to TRAP and whether doing so has benefits for cardiovascular health.

Social support and strain and emotional distress among Latinos in the northeastern United States.

BACKGROUND: US Latinos report high levels of emotional distress. Having positive familial and friend social support buffers emotional distress among US Latinos, but thus far no research has been done on social support and ataque de nervios in that population, or on social strain and emotional distress. METHODS: This paper assesses social support and strain across three relationship types (partner, family, and friends) with three measures of emotional distress (depression, anxiety, and ataque de nervios). The sample for partner, family, and friend support included 508 Latino adults 21 and older. Multivariate logistic regression models were used to assess the association of social support and strain with each outcome. RESULTS: As all social support types increased, the odds of emotional distress symptoms decreased. Conversely, as each unit of partner and family strain increased, the odds of emotional distress symptoms increased. Increased friend strain was associated with greater odds of depressive and anxiety symptoms only. CONCLUSION: Social support in all three network types (partner, family, and friend) was associated with a decrease in the odds of emotional distress, assessed as symptoms of depression, anxiety, and ataque de nervios.
