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

Contemp Clin Trials 2021 Jul 28;108:106520. Epub 2021 Jul 28.

Department of Public Health and Community Medicine, Tufts University, Boston, MA 02111, United States of America.

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.

Health Lens Analysis: A Strategy to Engage Community in Environmental Health Research in Action.

Sustainability 2021 Feb 6;13(4). Epub 2021 Feb 6.

Macro Department, Boston University School of Social Work, 264 Bay State Rd., Boston, MA 02215, USA.

Health Lens Analysis is a tool to facilitate collaboration among diverse community stakeholders. We employed HLA as part of a community based participatory research (CBPR) and action study to mitigate the negative health effects of TRAP and ultrafine particles (UFPs) in Somerville, MA. HLA is a Health in All Policies tool with previously limited implementation in a North American context. As part of the HLA, community and academic partners engaged residents from across near-highway neighborhoods in a series of activities designed to identify health concerns and generate recommendations for policies and projects to improve health over an 18-month planning period. Noise barriers, which may reduce TRAP exposure among residents in addition to reducing traffic noise, were seen as an acceptable solution by community stakeholders. We found HLA to be an effective means to engage stakeholders from across sectors and diverse community residents in critical discourse about the health impacts of near-roadway exposures. The iterative process allowed the project team to fully explore the arguments for noise barriers and preferred health interventions, while building a stakeholder base interested in the mitigation of TRAP, thus, creating a shared language and understanding of the issue.

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

BMC Psychol 2021 Mar 7;9(1):40. Epub 2021 Mar 7.

Division of Preventive and Behavioral Medicine, University of Massachusetts Medical School, Worcester, MA, 01655, USA.

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.

Neighborhood characteristics and ataque de nervios: the role of neighborhood violence.

Transcult Psychiatry 2020 Jul 21:1363461520935674. Epub 2020 Jul 21.

University of Massachusetts Medical School.

Ataque de nervios is a Latina/o idiom of distress that may occur as a culturally sanctioned response to acute stressful experiences, particularly relating to grief, threat, family conflict, and a breakdown in social networks. The contextual factors associated with ataque de nervios have received little attention in research. This study examined the association between neighborhood factors and the experience of ataque de nervios among a sample of Latinas/os participating in the Latino Health and Well-Being Project in the northeastern United States. We examined the association between neighborhood cohesion, safety, trust, and violence and ataque de nervios. In multivariate logistic regression models, neighborhood violence was associated with ataque de nervios ( = .02), with each unit increase in the neighborhood violence scale being associated with 1.36 times greater odds of experiencing ataque de nervios. None of the other neighborhood variables were significantly associated with ataque de nervios. The positive association between neighborhood violence and the experience of ataque de nervios makes a further case for policy efforts and other investments to reduce neighborhood violence.
