Background: Environmental health risks are disproportionately colocated with communities in poverty and communities of color. In some cases, participatory research projects have effectively addressed structural causes of health risk in environmental justice (EJ) communities. However, many such projects fail to catalyze change at a structural level. Objectives: This review employs Critical Interpretive Synthesis (CIS) to theorize specific elements of participatory research for environmental health that effectively prompt structural change in EJ communities. Methods: Academic database search was used to identify peer-reviewed literature describing participatory research with EJ communities to address environmental health. Synthetic constructs were developed iteratively related to study characteristics, design elements, and outcomes; and data were extracted for included records. Statistical analyses were performed to assess correlations between study design elements and structural change outcomes. Through critical, comparative, and contextual analyses of the "structural change" case study group and "non- structural change" group, informed by relevant theoretical literature, a synthesizing argument was generated. Results: From 505 total records identified, eligibility screening produced 232 case study articles, representing 154 case studies, and 55 theoretical articles for synthesis. Twenty-six case studies resulted in a structural change outcome. The synthesizing argument states that participatory research with EJ communities may be more likely to result in structural change when a) community members hold formal leadership roles; b) project design includes decision-makers and policy goals; and c) long term partnerships are sustained through multiple funding mechanisms. The assumption of EJ community benefit through research participation is critically examined. Discussion: Recommended future directions include establishing structural change as a goal of participatory research, employing participatory assessment of community benefit, and increased hiring of faculty of color at research institutions. The power, privilege, and political influence that academic institutions are able to leverage in partnership with EJ communities may be as valuable as the research itself. https://doi.org/10.1289/EHP6274.

Environmental health citizen science (CS) offers a strategy for historically disenfranchised community members to inform research questions, collect and analyze data, and draw conclusions about contaminants in their local environments to inform local action. In this study, direct feedback from demographically diverse participants and 'promotoras' (community health workers) in a co-created environmental health CS project informs understanding of CS participant motivation, support, and barriers to participation. Study findings reflect a lack of association between participant self-efficacy and race, income, or education level, respectively; however specific types of motivation, participation support, and barriers to participation were found to be more relevant among participants of certain demographic groups or communities compared to others. These findings inform the following recommendations for engaging diverse CS participants: 1) Consider existing relationships and community-identified problems as participant motivation, 2) Design participant methods to include personal support structures and relationship-building, and, 3) Design for participant time and technology access as significant limitations to participation. These findings serve to inform best practices in environmental health CS, as well CS project design for diverse participants.

Environmental health literacy (EHL) has recently been defined as the continuum of environmental health knowledge and awareness, skills and self-efficacy, and community action. In this study, an interdisciplinary team of university scientists, partnering with local organizations, developed and facilitated EHL trainings with special focus on rainwater harvesting and water contamination, in four communities with known environmental health stressors in Arizona, USA. These participatory trainings incorporated participants’ prior environmental health risk knowledge and personal experiences to co-create training content. Mixed methods evaluation was conducted via pre-post participant surveys in all four trainings (n = 53). Participants who did not demonstrate baseline environmental science knowledge pre-training demonstrated significant knowledge increase post-training, and participants who demonstrated low self-efficacy (SE) pre-training demonstrated a significant increase in SE post-training. Participants overall demonstrated a significant increase in specific environmental health skills described post-training. The interdisciplinary facilitator-scientist team also reported multiple benefits, including learning local knowledge that informed further research, and building trust relationships with community members for future collaboration. We propose contextual EHL education as a valuable strategy for increasing EHL in environmental health risk communities, and for building academia-community partnerships for environmental health research and action.
