'It doesn't happen any other way': relationship-building and reflexivity for equity-focused intersectoral practice (EquIP).

Intersectoral processes that bring together public institutions, civil society organizations and affected community members are essential to tackling complex health equity challenges. While conventional wisdom points to the importance of human relationships in fostering collaboration, there is a lack of practical guidance on how to do intersectoral work in ways that support authentic relationship-building and mitigate power differentials among people with diverse experiences and roles. This article presents the results of RentSafe EquIP, a community-based participatory research initiative conducted in Owen Sound, Canada, in the midst of a housing crisis. The research explored the potential utility of equity-focused intersectoral practice (EquIP), a novel approach that invests in human relationships and knowledge co-creation among professionals and affected members of the community. The three-phase EquIP methodology centred the grounded expertise of community members with lived/living experience of housing inadequacy to catalyze reflexive thinking by people in professional roles about the institutional gaps and barriers that prevent effective intersectoral response to housing-related inequities. The research demonstrated that EquIP can support agency professionals and community members to (i) engage in (re)problematization to redefine the problem statement to better include upstream drivers of inequity, (ii) support reflexivity among those in professional roles to identify institutional practices, policies and norms that perpetuate stigma and impede effective intersectoral response and (iii) spark individual and collective agency and commitment towards a more equity-focused intersectoral system. We conclude that the EquIP methodology is a promising approach for communities seeking to address persistent health equity and social justice challenges.

Development and Validation of the Prevention of Toxic Chemicals in the Environment for Children Tool: A Questionnaire for Examining the Community's Knowledge of and Preferences Toward Toxic Chemicals and Children's Brain Development.

Early-life exposures to toxic chemicals can adversely impact brain development. Understanding people's knowledge of the impact of toxic chemicals on brain development is critical to reduce widespread exposure to chemicals. Yet it is unknown what people know about risks of toxic chemicals and how to reduce exposures. We developed and validated the questionnaire, PRevention of Toxic chemicals in the Environment for Children Tool (PRoTECT), to examine people's knowledge and attitudes about the influence of toxic chemicals on child development. We used best practices for developing and validating scales. First, we drafted items to assess knowledge of the impact of toxic chemicals on brain development, levels of concern regarding exposures, and preferences for prevention of neurodevelopmental disorders. Second, we received feedback on item clarity from five focus groups consisting of 46 community participants. In addition, 17 experts completed a content validity scale for each item and provided qualitative feedback. We administered the revised 18-item questionnaire to 190 participants of child-bearing age for scale development, and using exploratory factor analysis, we found evidence for a four-factor model of PRoTECT, RMSR = 0.05, of which 16 of the 18 items had adequate content validity with loadings >0.40 on a derived factor. We discuss future directions and applications of PRoTECT.

Lessons from a rural housing crisis: grounded insights for intersectoral action on health inequities.

Local communities are struggling with persistent health inequities driven by income disparity, housing inadequacy, and other intersecting factors that constrain individual and community well-being. Increasingly, intersectoral approaches are recognized as essential to tackle such challenges, given their intersecting nature. This paper describes Equity-focused Intersectoral Practice (EquIP), a novel methodology that merges participatory research principles with the purposeful positioning of grounded expertise (lived experience) to shift the gaze of intersectoral actors towards the contextual factors that contribute to health inequities. The EquIP methodology creates uncommon spaces for intersectoral encounter that support critical reflexivity and relationship-building among institutional and community-based intersectoral actors. A case example of the EquIP methodology, implemented in a small, rural Canadian city in the context of a regional housing crisis, illustrates how investment in reflexivity and relational praxis among diverse intersectoral actors supports the identification of existing structures, beliefs, and practices within institutional settings that constrain effective intersectoral response to health inequities.

Interdisciplinary-driven hypotheses on spatial associations of mixtures of industrial air pollutants with adverse birth outcomes.

BACKGROUND: Adverse birth outcomes (ABO) such as prematurity and small for gestational age confer a high risk of mortality and morbidity. ABO have been linked to air pollution; however, relationships with mixtures of industrial emissions are poorly understood. The exploration of relationships between ABO and mixtures is complex when hundreds of chemicals are analyzed simultaneously, requiring the use of novel approaches. OBJECTIVE: We aimed to generate robust hypotheses spatially linking mixtures and the occurrence of ABO using a spatial data mining algorithm and subsequent geographical and statistical analysis. The spatial data mining approach aimed to reduce data dimensionality and efficiently identify spatial associations between multiple chemicals and ABO. METHODS: We discovered co-location patterns of mixtures and ABO in Alberta, Canada (2006-2012). An ad-hoc spatial data mining algorithm allowed the extraction of primary co-location patterns of 136 chemicals released into the air by 6279 industrial facilities (National Pollutant Release Inventory), wind-patterns from 182 stations, and 333,247 singleton live births at the maternal postal code at delivery (Alberta Perinatal Health Program), from which we identified cases of preterm birth, small for gestational age, and low birth weight at term. We selected secondary patterns using a lift ratio metric from ABO and non-ABO impacted by the same mixture. The relevance of the secondary patterns was estimated using logistic models (adjusted by socioeconomic status and ABO-related maternal factors) and a geographic-based assignment of maternal exposure to the mixtures as calculated by kernel density. RESULTS: From 136 chemicals and three ABO, spatial data mining identified 1700 primary patterns from which five secondary patterns of three-chemical mixtures, including particulate matter, methyl-ethyl-ketone, xylene, carbon monoxide, 2-butoxyethanol, and n-butyl alcohol, were subsequently analyzed. The significance of the associations (odds ratio > 1) between the five mixtures and ABO provided statistical support for a new set of hypotheses. CONCLUSION: This study demonstrated that, in complex research settings, spatial data mining followed by pattern selection and geographic and statistical analyses can catalyze future research on associations between air pollutant mixtures and adverse birth outcomes.

Towards equity-focused intersectoral practice (EquIP) in children's environmental health and housing: the transformational story of RentSafe.

SETTING: This paper chronicles the transformational process through which a national intersectoral collaboration, the Canadian Partnership for Children's Health and Environment (CPCHE), came to embrace a more upstream, equity-based focus in its mandate to advance children's environmental health. INTERVENTION: After 15 years of working within a conventional, evidence-informed approach to health promotion and policy advocacy, in 2010-2013, CPCHE had the opportunity to collaborate on the development of equity-focused knowledge translation (EqKT). EqKT is a relational approach to knowledge practices that challenges intersectoral actors to work to uncover biases and limitations within their own institutional paradigms and professional practices that constrain their capacity to address population health inequities. OUTCOME: The ensuing transformation towards equity-focused intersectoral practice led CPCHE to create an intersectoral initiative called RentSafe. Conceptually and operationally, RentSafe provides an intersectoral space within which the grounded expertise of people with experience of unhealthy and undignified housing provides a roadmap for public health and other practitioners to critically explore professional and institutional blind spots and barriers. With RentSafe as its watershed moment, CPCHE is shifting from a top-down "for whom" orientation to an authentically engaged "with whom" approach that seeks to work integrally with community partners to expose and challenge systemic roots of health inequity. IMPLICATIONS: The transformational story of CPCHE underscores the competencies needed for public health professionals to acknowledge the sources of our own biases and limitations as a necessary first step in equity-focused intersectoral practice (EquIP). It also affirms the value of working in partnership with those who experience the environmental health inequities that such efforts seek to address.
