Black women are sorely underrepresented in studies of Alzheimer\'s disease and related dementias (ADRD) despite higher rates of ADRD diagnoses than in non-Hispanic White women. There are many reasons for underrepresentation, including medical mistrust, limited access to clinical studies, and restrictive study inclusion criteria. These pervasive barriers to research participation are often not considered during study development and, if eventually thought of tend to be after the fact. Community-engaged research (CER) approaches are an effective method for reducing participation barriers. This article describes how CER approaches were used to develop the Black Women Inflammation and Tau Study (BWITS), a prospective study to identify biopsychosocial risk factors for ADRD in Black women. Guidelines discussed here for future ADRD research in diverse populations are informed by Community-Based Participatory Research (CBPR), the National Institute on Minority Health and Health Disparities (NIMHD), and the Patient-Centered Outcomes Research Institute (PCORI). HIGHLIGHTS: Understand the historical tragedies related to medical practices and research designs that may contribute to the underrepresentation of Black Americans in research studies today. Highlight community-engaged research approaches that effectively reduce participation barriers in minoritized groups. Review Community-Based Participatory Research, National Institute of Minority Health and Health Disparities, and the Patient-Centered Outcomes Research Institute guidelines for conducting research with minoritized communities. Describe using the three frameworks to inform the study development protocol for the Black Women Inflammation and Tau Study. Conclude by offering study design considerations that we hope can be a helpful starting point for others conducting research with minoritized communities.

OBJECTIVE: Food insecurity is associated with eating disorder psychopathology. This Spotlight describes why food pantries could be promising partners for disseminating and implementing eating disorder interventions.
METHODS: Researchers are increasingly collaborating with community-based organizations to improve access to health interventions, because community-based organizations overcome structural barriers to traditional healthcare by being embedded physically in the communities they serve, convenient to visit, regularly frequented, and led by trusted community members.
RESULTS: We describe strategies we have identified with our partner to disseminate and implement our digital intervention for binge eating; we also discuss ways we support the pantry\'s needs to improve the mutuality of the partnership.
CONCLUSIONS: The potential benefits of partnerships with food pantries make this an area to explore further. Future research directions include deeply engaging with food pantries to determine how pantries benefit from disseminating and implementing eating disorder interventions and how to intervene in non-stigmatizing ways, what resources they need to sustainably support these efforts, what eating disorder intervention modalities guests are willing and able to engage with, what intervention adaptations are needed so individuals with food insecurity can meaningfully engage in eating disorder intervention, and what implementation strategies facilitate uptake to intervention sustainably over time.

UNASSIGNED: Community advisory boards (CABs) and researcher partnerships present a promising opportunity to accelerate enrollment of underrepresented groups (URGs). We outline the framework for how the CAB and researchers at the Indiana Alzheimer\'s Disease Research Center (IADRC) partnered to accelerate URG participation in AD neuroimaging research.
UNASSIGNED: CAB and the IADRC researchers partnered to increase the CAB\'s impact on URG study enrollment through community and research interactions. Community interactions included the CAB collaboratively building a network of URG focused community organizations and collaborating with those URG-focused organizations to host IADRC outreach and recruitment events. Research interactions included direct impact (CAB members referring themselves or close contacts as participants) and strategic impact, mainly by the CAB working with researchers to develop and refine URG focused outreach and recruitment strategies for IADRC and affiliated studies to increase URG representation. We created a database infrastructure to measure how these interactions impacted URG study enrollment.
UNASSIGNED: Out of the 354 URG research referrals made to the IADRC between October 2019 and December 2022, 267 referrals were directly referred by the CAB (N = 36) or from community events in which CAB members organized and/or volunteered at (N = 231). Out of these 267 referrals, 34 were enrolled in IADRC and 2 were enrolled in Indiana University Longitudinal Early Onset AD Study (IU LEADS). Of note, both studies require the prospective participants to be willing to do MRI and PET scans. As of December 2022, 30 out of the 34 enrolled participants have received a consensus diagnosis; the majority were cognitively normal (64.7%), with the remainder having mild cognitive impairment (17.6%) or early-stage AD (2.9%).
UNASSIGNED: The IADRC CAB-researcher partnership had a measurable impact on the enrollment of African American/Black adults in AD neuroimaging studies. Future studies will need to test whether this conceptual model works for other sites and for other URGs.

Urban agriculture is emerging as a method to improve food security and public health in cities across the United States. However, an increased risk of exposure to heavy metals and metalloids (HMM) exists through interaction with contaminated soil. Community-engaged research (CEnR) is one method that can promote the inclusion of all partners when studying exposures such as HMM in soil. Researchers and community gardeners co-designed this study to measure the concentrations of lead (Pb), using X-Ray Fluorescence (XRF) verified with Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) in soils from 19 urban agricultural and residential sites in the Westside of Atlanta and three rural sites in Georgia. Seventeen other HMM were measured but not included in this study, because they did not pose risks to the community comparable to elevated Pb levels. Pb concentrations were compared to the Environmental Protection Agency (EPA)\'s regional screening levels (RSLs) for residential soil and the University of Georgia (UGA) extension service\'s low-risk levels (LRLs) for agriculture. Soils from the majority of sites had levels below EPA RSLs for Pb, yet above the UGA LRL. However, soil Pb concentrations were three times higher than the EPA RSL on some sites that contained metal refining waste or slag. Our findings led to direct action by local and federal government agencies to initiate the cleanup of slag residue. Studies involving exposures to communities should engage those affected throughout the process for maximum impact.

The editorial focuses on four major themes contextualized in a virtual GeoHealth workshop that occurred from June 14 to 16, 2021. Topics in that workshop included drinking water and chronic chemical exposure, environmental injustice, public health and drinking water policy, and the fate, transport, and human impact of aqueous contaminants in the context of climate change. The intent of the workshop was to further define the field of GeoHealth. This workshop emphasized on chemical toxicants that drive human health. The major calls for action emerged from the workshop include enhancing community engagement, advocating for equity and justice, and training the next generation.

GeoHealth as a research paradigm offers the opportunity to re-evaluate common research engagement models and science training practices. GeoHealth challenges are often wicked problems that require both transdisciplinary approaches and the establishment of intimate and long-term partnerships with a range of community members. We examine four common modes of community engagement and explore how research projects are launched, who has the power in these relationships, and how projects evolve to become truly transformative for everyone involved.
