Background

Asian Americans experience significant health disparities yet remain politically underrepresented. Political participation—a social determinant of health—may be a mechanism for communities to advocate for health resources and policies. This study examines contextual factors influencing political participation in segregated Asian American neighborhoods, with attention to health equity implications.

Methods

We conducted 11 virtual focus groups with 42 Southeast Asian American residents (Filipino, Vietnamese, Hmong, Cambodian) in three California regions. Using participatory community mapping and qualitative analysis, we explored political participation patterns, contextual promoters and barriers, and connections to community health.

Results

Participants identified both structural, spatial, and social factors affecting political participation with implications for health equity. Structural promoters included community health organizations, which explicitly linked civic engagement to health advocacy, and faith-based organizations providing trusted spaces for political education. Barriers included lack of centralized Asian American spaces and language-inaccessible venues. Social factors included generational differences in political engagement, with older immigrants expressing fear of participation rooted in trauma; and cultural pressure to “not rock the boat,” limiting health advocacy.

Discussion

Political participation inequities in Asian American communities represent a critical but overlooked determinant of health disparities. Low engagement leads to policy neglect and inadequate health resource allocation. Community health organizations provide promising intervention points. Results inform place-based strategies to promote political participation as a health equity approach, particularly urgent given anti-Asian violence and pandemic impacts on these communities.

Duarte, C. dP, Khadka, A., Ahern, J., Manly, J., Yen, I. H., Cohen, A. K., & Vable, A. M. (2026). Examining associations between school suspension and expulsion in early life and later-life cognitive health: A mediation analysis of lifecourse educational pathways. Social Science & Medicine. https://doi.org/10.1016/j.socscimed.2026.119475

Exclusionary school discipline (e.g., suspension, expulsion) – a documented facilitator of structural marginalization – is associated with lower midlife cognitive health, a predictor of later-life dementia risk. No studies have examined through which mechanisms this might unfold. Using National Longitudinal Survey of Youth 1979 data, a study of US adults followed prospectively since adolescence (N=8,138), we evaluated if lifecourse educational trajectories mediate this relationship. First, we estimated associations between exposure to early-life exclusionary discipline (no vs. any suspension/expulsion prior to 1980) and participants’ age 14-48 educational trajectories. We then evaluated whether these lifecourse educational trajectories mediate the association between exclusionary school discipline and later-life cognitive health (global cognition z-score; mean age at cognitive assessment: 55.2 years) using inverse odds weighting to estimate total, natural direct (NDE), and natural indirect (NIE) effects. Participants who were men, Black, had lower childhood socioeconomic status, or were born in the southern US were overrepresented in early-life exclusionary discipline. Suspension/expulsion was associated with educational trajectories characterized by lower attainment (e.g., less-than high school, HS), completed later in life (e.g., General Educational Development HS equivalency exam, GED, after long delay/late 30s), and following early exit from HS without a diploma (e.g., some college after GED). Suspension/expulsion was also associated with lower later-life global cognition (z-score mean difference: -0.226; 95%CI: -0.230, -0.223) and this relationship was mediated by the education trajectories (mediation proportion:47.2%; NIE: -0.107; 95%CI: -0.110, -0.104; NDE: -0.120; 95%CI: -0.124, -0.115). Findings suggest exclusionary school discipline, which is modifiable at multiple policy levels, is associated with later-life cognitive health by interrupting educational progress or pushing students out of the education system altogether.

Introduction

Little is known about whether neighborhood social and built environments influence Alzheimer's disease (AD) dementia risk in South Asian individuals.

Methods

We used data on 745 South Asian individuals living in the United States (US) who were ≥40 years old. Neighborhood characteristics included percentage of Asian residents, Walk Score (walkability), and neighborhood social cohesion. We calculated an AD dementia risk score from age, gender, education, diabetes, hypertension, current smoking, low high-density lipoprotein, and high waist-to-hip ratio. Multivariable linear regression examined associations between neighborhood characteristics and AD dementia risk scores; interaction terms tested for differences by gender.

Results

Greater neighborhood social cohesion was associated with lower AD dementia risk scores in the overall sample. Stratifying by gender, the beneficial association was only observed for women and not men (interaction p-value: 0.01).

Conclusion

Policies and interventions promoting neighborhood social cohesion may help reduce AD dementia risk among South Asian middle and older-age women in the United States.

Murillo, J., Pulido, T. R., Loyd, A. B., Subica, A. M., Yen, I. H., & Payán, D. D. (2025). Policy stakeholders’ perspectives and use of data, research evidence, and misinformation in three counties in California, USA during the COVID-19 pandemic, 2020–2022. Preventive Medicine Reports, 54, Article 103098. https://doi.org/10.1016/j.pmedr.2025.103098 (Original work published 2025)

Objective

This study investigates how local policy stakeholders viewed and used research evidence, data, and (mis)information in county policy discussions during the COVID-19 pandemic.

Method

We employed document and exploratory content analysis methods to examine Board of Supervisor materials (N = 534 policy documents) from general and special/emergency meetings (March 2020 – December 2022). We purposefully selected three jurisdictions from California, USA with varying socio-demographic, political, and health care characteristics as case studies.

Results

Many residents who commented during local policy discussions contested the: 1) validity of health data provided (i.e., mortality rates), and 2) efficacy of proposed preventive measures like mask wearing and vaccine receipt. While government officials and healthcare personnel referenced research evidence and data as justification for these measures, several stakeholders expressed skepticism about the information presented in all three counties. Perceptions of misinformation included statements by residents that questioned the COVID-19 information provided by government officials or reflected a belief that federal and state government agencies (e.g., Centers for Disease Control and Prevention, CDC) were sources of misinformation. An emergent finding was that many residents voiced uncertainty and requested more information about local pandemic conditions and policy mitigation strategies.

Conclusions

Results reveal a distrust of public health and government officials and data/information shared in local policymaking debates during the COVID-19 pandemic. Local health departments may benefit from investing in efforts to increase their credibility as trusted sources of health information among community members. Local government agencies should develop transparent health promotion campaigns to identify and dispel misinformation.

Community-Led Solutions: How Local Organizing Committees Drive Change for Housing and Health Equity in California’s Central Valley. Journal of Participatory Research Methods, 5(2). https://doi.org/10.35844/001c.120257 (Original work published 2024)

In this research brief, we describe how the HOPe Lab (UC Merced), Faith in the Valley (Fresno), and Cultiva Central Valley (Merced) are collaborating to address housing-related disparities within California’s culturally diverse Central Valley. Focused on the transformative role of Local Organizing Committees (LOCs), our research employs an anti-racist research praxis to actively engage residents, enhance leadership capacity, and foster communication between residents and elected officials. Drawing on several theory-of-change statements and the practical insights gained from “field experts” carrying out ongoing initiatives, this report explores the positive impact of LOCs on meaningful community involvement, empowerment, engagement, accountability, and policy changes.

Progress in Community Health Partnerships: Research, Education, and Action, 18(1), 1-9. (Original work published 2024)

Objective: We sought to examine the experiences of community partners in a community–academic partnership to promote COVID-19 testing in two majority Latino communities.

Methods: We conducted semistructured, in-depth interviews in English and Spanish with community-based organization leaders and community health workers/promotoras (n = 10) from June to July 2021. Interviews focused on identifying partner roles in planning and testing implementation and evaluating communication among partners. Interviews were transcribed and analyzed in ATLAS.ti version 8.4.5. Analyses involved deductive and inductive approaches to identify key themes.

Results: Participants described both strengths and challenges to the collaborative approach within each of three core themes: building relationships in the time of COVID-19; uplifting existing community leadership; and commitment of the academic partners and community-based organizations to conduct partnership activities in Spanish.

Conclusion: Community–academic partnerships that invest in strong relationships, community leadership, and a commitment to the community's preferred language offer a promising approach to addressing COVID-19 testing barriers. Findings provide direction for future research on how community members and academic partners can come together to inform strategies to continue addressing the COVID-19 pandemic.

Mixed Methods for Research on Support Networks of People Experiencing Chronic Illness and Social Marginalization. Qualitative Health Research, 1-14. https://doi.org/10.1177/10497323241235031 (Original work published 2024)

Substantial research has focused on how social networks help individuals navigate the illness experience. Sociologists have begun to theorize beyond the binary of strong and weak social network ties (e.g., compartmental, elastic, and disposable ties), citing the social, economic, and health conditions that shape their formation. However, limited research has employed mixed social network methods, which we argue is especially critical for examining the “non-traditional” social support networks of marginalized individuals. We employ quantitative social network methods (i.e., the egocentric network approach) in addition to in-depth interviews and observations, with a novel tool for capturing network data about social groups, to surface these kinds of supportive relationships. Using the case of “nameless ties”—non-kin, non-provider ties who were unidentifiable by given name or were grouped by context or activity rather than individually distinguished—we show how mixed social network methods can illuminate supporters who are commonly overlooked when only using traditional social network analysis. We conclude with a proposal for mixed methods and group alter approaches to successfully observe liminal support ties that is ideal for research about individuals experiencing chronic disability, poverty, housing insecurity, and other forms of social marginalization.

Social support in the urban safety net: Assessing tie activation among individuals with complex care needs. Journal of Social and Personal Relationships, 1-24. https://doi.org/10.1177/02654075241229748 (Original work published 2024)

Activating social ties is a critical mechanism for satisfying individuals’ social, emotional, and material needs. Researchers have offered a number of hypotheses around tie activation about when and why particular supporters step in to help, ranging from strategic activation via functional specificity to opportunistic mobilization. To date, few studies have examined multiple tie activation strategies in tandem. This project focuses on people facing complex, compounding health and social problems, who may have to rely on multiple forms of activation to get their support needs met. We draw on a sample of 92 participants who are affiliated with one of two Care Management programs in the Western United States. Using name generators in a survey, we elicit participants’ social networks and find they utilize a number of methods to secure critical support needs, including calling on kin ties to borrow money and help with daily tasks, relying on strong and proximal ties for almost all types of support, and using functional specificity for health support. We then draw on qualitative interviews to gain a deeper understanding of the ways alters provide support and why egos elicit support from some alters and not others. Future research should continue assessing this population’s social networks with the aim of leveraging social support to help manage chronic conditions, provide access to resources, and increase their sense of belonging.

Dubbin, L., & Yen, I. H. (2023). Renovating space to age in place: Experiences of elderly residents living through public housing renovations and reflections from affordable housing developers. Journal of Aging and Environment. https://doi.org/10.1080/26892618.2023.2280961 (Original work published 2023)

In this article, we explore the experiences of older adults living in public housing undergoing renovations and its associated impacts on their perceived sense of well-being. We also consider the ways in which affordable housing developers contemplate residents’ health and wellness into renovation plans and processes. Following the conventions of hermeneutic analysis, we conducted open-ended in-depth interviews with older adults living in public housing undergoing renovations (n = 21) and representatives of a variety of affordable housing developers (n = 12). Our analysis demonstrates that residents had strong attachments to their individual living spaces prior to renovations and were fiercely protective of them. Renovations created a sense of unease among older residents as the familiar features of their homes were altered. The processes and the outcomes of renovations and new management strategies raised fears that their lived environments were becoming institutionalized. Developers acknowledged that a tension exists between residents’ desires for personalized private space, and their responsibilities as landlords to prioritize the physical safety of residents and the fiduciary obligations to maintain building longevity.

Education and Urban Society, 56(6), 655-681. https://doi.org/10.1177/00131245231193406 (Original work published 2023)

As part of a larger project focused on the intersection of educational and health trajectories over the life course, we use in-depth interviews with 28 adults who experienced multiple non-promotional school changes during the course of their K-12 schooling in three U.S. urban centers to advance understanding of frequent student mobility. Prior research focuses predominantly on isolating the impact of student mobility while saying little about processes through which mobility influences educational trajectories in particular contexts. Frequent student mobility was intertwined with adverse childhood experiences and access to coping resources, and these forces shaped participants’ trajectories in patterned ways. Supporting frequently mobile students, almost a third of school-age children in the United States, will require greater attention to the reasons for, processes of, and contexts of student mobility.
