Defining the Exposome Using Popular Education and Concept Mapping With Communities in Atlanta, Georgia.

Introduction: The exposome concept provides a framework to better incorporate the environment into the study of health and disease and has been defined by academics to encompass all lifetime exposures including toxicants, diet, and lifestyle choices. However, initial applications of the exposome concept have been less apt at measuring social determinants of health, focusing primarily on conventional environmental exposures and lifestyle choices that do not reflect the complex lived experience of many communities. To bring community voice into the exposome concept, the HERCULES Exposome Research Center and its Stakeholder Advisory Board co-developed the Exposome Roadshow. We present and discuss the resulting community-exposome definition to inform and improve exposome research. Materials and Methods: Four communities from distinct areas across metro-Atlanta participated in separate 2-day Exposome Roadshow workshops with concept mapping. Aligned with a popular education approach in which community knowledge is used to work collectively for change, concept mapping provided a systematic method to collect and visualize community members' knowledge and create a shared understanding to take action. Community members brainstormed, sorted, and rated their responses to the prompt: "What in your environment is affecting your and your community's health?" Responses were analyzed and visually depicted by concept maps consisting of separate but interrelated clusters of ideas. Community members discussed and validated the maps, selecting a final map illustrating their community's exposome. Results: A total of 118 community members completed concept mapping. On average communities identified 7 clusters to define their exposome. The resulting concept maps offer a community definition of the exposome. Five major themes arose across all four communities: conventional environmental concerns, built environment, social relationships, crime and safety, and individual health and behaviors. Discussion: The resulting community-exposome definition demonstrates the importance of expanding the scope of exposures beyond traditional environmental influences to include the lived experience of individuals and communities. While newer exposome definitions align more closely with this community definition, traditional exposome methods do not routinely include these factors. To truly capture the totality of lifetime exposures and improve human health, researchers should incorporate community perspectives into exposome research.

Community-Based Participatory Approach to Increase African Americans' Access to Healthy Foods in Atlanta, GA.

African Americans in Atlanta, Georgia disproportionately reside in communities with limited access to healthy foods. Collaborations with local corner stores to provide healthy food options have been identified as an evidence-based intervention that could be used to increase food access. This paper describes the community-based participatory approach used to culturally-tailor a Healthy Corner Store Initiative (HCSI) in five Atlanta communities. A mixed method approach (qualitative/quantitative) was utilized. Spatial analysis and an environmental assessment were conducted to locate all corner stores in the partner communities that were listed in a business database. An environmental assessment was conducted at 34 corner stores using a structured log and checklist. Among them, 11 were selected and signed memorandums of understanding to implement the HCSI. A customer intercept survey was administered to 100 African American corner store customers at five of the healthy corner store sites. Descriptive statistics were used to analyze log/checklist and survey data. Corner store customers indicated that they typically purchase snacks, tobacco, and breads, but would purchase certain healthy foods, if offered. They also indicated that freshness of fruits and vegetables and positive relationships with corner store owners would influence healthy food purchases. Findings demonstrate that working collaboratively with community members, researchers and business owners is a critical step in nurturing trust, strengthening credibility, and building partnerships towards increased healthy food access and improved community health.

The impact of implementing selected CBPR strategies to address disparities in urban Atlanta: a retrospective case study.

In 2005, the Institute of Public Health at Georgia State University (GSU) received a 3-year community-based participatory research (CBPR) grant from the National Center for Minority Health and Health Disparities entitled Accountable Communities: Healthy Together (ACHT). Because urban health disparities result from complex interactions among social, economic and environmental factors, ACHT used specific CBPR strategies to engage residents, and promote the participation of community organizations serving, a low-income community in urban Atlanta to: (i) identify priority health and social or environmental problems and (ii) undertake actions to mitigate those problems. Three years after funding ended, a retrospective case study, using semi-structured, taped interviews was carried out to determine what impacts, if any, specific CBPR strategies had on: (i) eliciting resident input into the identification of priority problems and (ii) prompting actions by community organizations to address those problems. Results suggest that the CBPR strategies used were associated with changes that were supported and sustained after grant funding ended. Insights were also gained on the longer term impacts of ACHT on community health workers. Implications for future CBPR efforts, for researchers and for funders, are discussed.
