BACKGROUND In recent years, public discourse has increasingly brought institutional and structural racism to the foreground of discussion on the well-being of BIPOC (Black, Indigenous, and People of Color) communities. Environmental toxicity in combination with the social triggers of institutional and structural racism are among the factors that shape the short- and long-term health of BIPOC Americans across multiple lifespans. OBJECTIVES We outline a 2+ Generation Model for examining the mechanisms through which institutional and structural racism promotes the intergenerational transmission of environmental health risk and family and interpersonal relationships across the life course and across multiple generations. We present the model's theoretical underpinnings and rationale, discuss model limitations and needed sources of data, and implications for research, policy, and intervention. DISCUSSION Parents and children are not only biologically linked in terms of transmission of environmental toxicities, but they are also linked socially and intergenerationally. The 2+ Generation Model foregrounds family and interpersonal relationships occurring within developmental contexts that are influenced by environmental toxicity as well as institutional and structural racism. In sum, the 2+ Generation Model highlights the need for an equity-first interdisciplinary approach to environmental health and redirects the burden of risk reduction away from the individual and onto the institutions and structures that perpetuate the racial disparities in exposure. Doing so requires institutional investment in expanded, multigenerational, and multimethod datasets. https://doi.org/10.1289/EHP13110.

黑人、原住民和有色人种 (BIPOC) 儿童和家庭的多代环境风险模型。


背景近年来，公共话语越来越多地将制度性和结构性种族主义带到了有关 BIPOC（黑人、土著和有色人种）社区福祉的讨论的前台。环境毒性与制度性和结构性种族主义的社会触发因素相结合，是影响 BIPOC 美国人多个生命周期短期和长期健康的因素之一。目标 我们概述了一个 2+ 代模型，用于研究制度性和结构性种族主义促进环境健康风险以及家庭和人际关系在整个生命历程和跨代的代际传播的机制。我们介绍该模型的理论基础和基本原理，讨论模型的局限性和所需的数据来源，以及对研究、政策和干预的影响。讨论 父母和孩子不仅在环境毒性传播方面存在生物学联系，而且在社会和代际方面也存在联系。 2+代模型强调了发展背景下发生的家庭和人际关系，这些关系受到环境毒性以及制度和结构性种族主义的影响。总之，2+代模型强调需要对环境健康采取公平第一的跨学科方法，并将减少风险的负担从个人转移到使种族暴露差异长期存在的机构和结构上。这样做需要对扩展的、多代的和多方法的数据集进行机构投资。 https://doi.org/10.1289/EHP13110。
