Contributions of Structural Racism to the Food Environment: A Photovoice Study of Black Residents With Hypertension in Baltimore, MD.

ABSTRACT:

Background

Disproportionate exposure to poor food environments and food insecurity among Black Americans may partially explain critical chronic disease disparities by race and ethnicity. A complex set of structural factors and interactions between Black residents and their food environments, including store types, quantity, proximity, and quality of goods and consumer interactions within stores, may affect nutritional behaviors and contribute to higher cardiovascular and kidney disease risk.

Methods

We used the Photovoice methodology to explore the food environment in Baltimore, MD, through the perspectives of Black residents with hypertension between August and November 2019. Twenty-four participants were enrolled in the study (mean age: 65.1 years; 67% female). After a brief photography training, participants captured photos of their food environment, which they discussed in small focus groups over the course of 5 weeks. Discussions were audiotaped and analyzed for emergent themes using a line-by-line inductive approach. Themes were, then, organized into a collective narrative.

Results

Findings describe physical and social features of the food environment as well as participants' perceptions of its origins and holistic and generational health effects. The study illustrates the interrelationships among the broader socio-political environment, the quality and quantity of stores in the food landscape, and the ways in which they engage with the food environment as residents and consumers who have been marginalized due to their race and/or social class. The following meta-themes emerged from the data: (1) social injustice; (2) structural racism and classism; (3) interpersonal racism; (4) generational effects; (5) mistrust; (6) social programs; and (7) community asset-based approaches, including advocacy and civic engagement.

Conclusions

Understanding residents' perceptions of the foundations and effects of the food environment on their health may help stakeholders to cocreate multilevel interventions alongside residents to improve access to healthy food and health outcomes among disparities affected populations.

Project description:ImportanceUncertainty remains among clinicians regarding processes to address and resolve conflict around anti-Black racism.ObjectiveTo elicit clinicians' perceptions of their role in addressing concerns about anti-Black racism among Black patients with serious illness as well as their families.Design, setting, and participantsIn this qualitative study, one-on-one semistructured interviews were conducted with 21 physicians at an academic county hospital between August 1 and October 31, 2022. Participants were provided clinical scenarios where anti-Black racism was a concern of a patient with serious illness. Participants were asked open-ended questions about initial impressions, prior similar experiences, potential strategies to address patients' concerns, and additional resources to support these conversations. A framework based on restorative justice was used to guide qualitative analyses.Main outcomes and measuresPerspectives on addressing anti-Black racism as described by physicians.ResultsA total of 21 medical subspecialists (mean [SD] age, 44.2 [7.8] years) participated in the study. Most physicians were women (14 [66.7%]), 4 were Asian (19.0%), 3 were Black (14.3%), and 14 were White (66.7%). Participants identified practices that are normalized in clinical settings that may perpetuate and exacerbate perceptions of anti-Black racism. Using provided scenarios and personal experiences, participants were able to describe how Black patients are harmed as a result of these practices. Last, participants identified strategies and resources for addressing Black patients' concerns and facilitating conflict resolution, but they stopped short of promoting personal or team accountability for anti-Black racism.Conclusions and relevanceIn this qualitative study, physicians identified resources, skills, and processes that partially aligned with a restorative justice framework to address anti-Black racism and facilitate conflict resolution, but did not provide steps for actualizing accountability. Restorative justice and similar processes may provide space within a mediated setting for clinicians to repair harm, provide accountability, and facilitate racial healing.

Project description:Racial disparities in many aging-related health outcomes are persistent and pervasive among older Americans, reflecting accelerated biological aging for Black Americans compared to White, known as weathering. Environmental determinants that contribute to weathering are poorly understood. Having a higher biological age, measured by DNA methylation (DNAm), than chronological age is robustly associated with worse age-related outcomes and higher social adversity. We hypothesize that individual socioeconomic status (SES), neighborhood social environment, and air pollution exposures contribute to racial disparities in DNAm aging according to GrimAge and Dunedin Pace of Aging methylation (DPoAm). We perform retrospective cross-sectional analyses among 2,960 non-Hispanic participants (82% White, 18% Black) in the Health and Retirement Study whose 2016 DNAm age is linked to survey responses and geographic data. DNAm aging is defined as the residual after regressing DNAm age on chronological age. We observe Black individuals have significantly accelerated DNAm aging on average compared to White individuals according to GrimAge (239%) and DPoAm (238%). We implement multivariable linear regression models and threefold decomposition to identify exposures that contribute to this disparity. Exposure measures include individual-level SES, census-tract-level socioeconomic deprivation and air pollution (fine particulate matter, nitrogen dioxide, and ozone), and perceived neighborhood social and physical disorder. Race and gender are included as covariates. Regression and decomposition results show that individual-level SES is strongly associated with and accounts for a large portion of the disparity in both GrimAge and DPoAm aging. Higher neighborhood deprivation for Black participants significantly contributes to the disparity in GrimAge aging. Black participants are more vulnerable to fine particulate matter exposure for DPoAm, perhaps due to individual- and neighborhood-level SES, which may contribute to the disparity in DPoAm aging. DNAm aging may play a role in the environment "getting under the skin", contributing to age-related health disparities between older Black and White Americans.
