The manuscripts Theorizing Epidemiology, the Stories Bodies Tell, and Embodied Truths: A Status Update on Contending 21st Century Epidemiological Theories of Disease Distribution by Nancy Krieger (2024) and Public Health Liberation - An Emerging Transdiscipline to Elucidate and Transform the Public Health Economy by Christopher Williams et al. (2022) present compelling frameworks for addressing health inequities to improve population health and advance health justice. Both works challenge the dominance of individualistic biomedical paradigms and advocate for structural approaches to public health. Two interpretations of these manuscripts—one provided by this system (Grok 3) and another attributed to ChatGPT—offer distinct analyses of how each manuscript tackles these dual goals. This essay synthesizes these interpretations, comparing the manuscripts across conceptual frameworks, engagement with structural determinants, practical applications, and inclusivity of community perspectives. It concludes by endorsing Williams et al. (2022) as the preferred manuscript, aligning with both interpretations but emphasizing its transdisciplinary, community-driven praxis as uniquely suited to the urgent demands of health justice in 2025.
Grok 3 describes Krieger’s work as a rigorous, academically grounded review of 21st-century epidemiological theories, with her ecosocial theory as a cornerstone. This theory posits health outcomes as “emergent embodied phenotypes” shaped by societal, ecological, and biological interactions across multiple levels and timescales, encapsulated in four constructs: embodiment, pathways of embodiment, cumulative interplay of exposure, susceptibility, and resistance, and agency and accountability (Krieger, 2024, p. 335). Grok 3 highlights Krieger’s critique of biomedical and lifestyle theories for their focus on individual-level factors, contrasting them with social epidemiological alternatives like social determinants of health (SDOH), political economy of health, and Latin American social medicine. Williams et al.’s Public Health Liberation (PHL) is framed as a transdisciplinary framework centered on the “public health economy,” integrating philosophy, theories, praxis, research, and training. PHL introduces novel constructs like “liberation,” “illiberation,” and the “Theory of Health Inequity Reproduction” (THIR), drawing from African American emancipatory thought, political theory, and community psychology to empower communities (Williams et al., 2022, pp. 11-14).
ChatGPT similarly positions Krieger’s manuscript as a theoretical examination of epidemiological frameworks, emphasizing her ecosocial theory’s concept of “embodiment” as a link between biology and political economy. It notes Krieger’s critique of biomedical and lifestyle models for isolating individuals from their social contexts and her advocacy for frameworks that address upstream determinants like racism and labor conditions. ChatGPT describes PHL as a prescriptive, transdisciplinary framework that views health as a political project within the “public health economy,” advocating for liberation through feminist, abolitionist, decolonial, and Indigenous epistemologies. It underscores PHL’s focus on dismantling oppressive structures and proposing actionable strategies like participatory budgeting and cooperative care models.
Both interpretations agree that Krieger’s ecosocial theory is a sophisticated, multilevel framework that integrates biological and social determinants, making it ideal for academic and policy analysis. Its strength lies in its systematic critique of dominant paradigms and its ability to explain how structural injustices manifest in health outcomes. However, its academic focus and dense theoretical language may limit its accessibility. PHL, as both interpretations note, is broader and more dynamic, transcending epidemiology to incorporate diverse disciplines and prioritize community agency. Grok 3 emphasizes PHL’s cultural specificity, particularly its African American liberation philosophy, while ChatGPT highlights its radical political stance and actionable proposals. PHL’s public health economy concept is less biologically grounded than ecosocial theory but more expansive in its systemic critique and practical orientation. While Krieger refines epidemiological theory, PHL reimagines public health as a liberatory practice, making it more responsive to grassroots needs.
Grok 3 underscores Krieger’s focus on social and structural determinants, detailing her analysis of SDOH, political and commercial determinants, and Latin American social medicine as alternatives to biomedical paradigms (Krieger, 2024, pp. 334-335). Her ecosocial theory links these determinants to biological embodiment, critiquing the marginalization of social epidemiology in funding and training (Krieger, 2024, p. 332). Grok 3 notes Krieger’s integration of intersectionality and decolonization to address intertwined injustices. For PHL, Grok 3 highlights the public health economy as a framework for understanding structural determinants, with THIR identifying social mobilization, constraints, economic incentives, and entrenched inequities as key components (Williams et al., 2022, p. 14). PHL’s emphasis on historical trauma and racialized experiences, particularly from slavery and Jim Crow, provides a culturally specific lens for structural analysis.
ChatGPT emphasizes Krieger’s critique of frameworks that medicalize health without addressing root causes like racism, housing, and environmental exposures. It highlights her ecosocial theory’s systemic approach to upstream determinants and power dynamics, though it notes her focus on scientific rigor over activist prescriptions. For PHL, ChatGPT describes the public health economy as a site where health is commodified and contested, critiquing privatization, austerity, and carceral logics. It praises PHL’s explicit engagement with abolitionist and Indigenous frameworks to address structural oppression and its call for mechanisms like solidarity economies to redistribute resources.
Both interpretations recognize that Krieger and PHL prioritize structural determinants over individualistic approaches. Krieger’s strength, as both note, is her rigorous, multilevel analysis that connects societal structures to physiological outcomes, supported by extensive data (e.g., Table 1, Krieger, 2024, p. 332). However, her focus remains within epidemiology, which may limit its scope. PHL, as both interpretations highlight, takes a broader, more radical approach, framing structural determinants within a competitive, anarchic public health economy. Grok 3 emphasizes PHL’s historical and racial specificity, while ChatGPT underscores its political and economic critique. PHL’s proactive stance—advocating for legal, social, and political interventions—contrasts with Krieger’s more cautious, theory-driven approach. While Krieger provides a robust explanatory framework, PHL’s transdisciplinary lens and focus on systemic transformation better address the complexity of structural inequities.
Grok 3 notes that Krieger advocates integrating social epidemiological theories into research, practice, and pedagogy, calling for explicit training to counter the dominance of biomedical models (Krieger, 2024, pp. 337-338). Her ecosocial theory has been applied to issues like cancer, racism, and climate change, but Grok 3 critiques its lack of concrete community-based examples, suggesting a top-down approach. For PHL, Grok 3 highlights its praxis-oriented approach, citing examples like advocacy against environmental racism and housing displacement in Washington, DC, and vaccination campaigns during COVID-19 (Williams et al., 2022, pp. 17-19). PHL’s training programs aim to equip communities with skills in law, policy, and organizing, ensuring sustainable change.
ChatGPT describes Krieger’s practical applications as focused on epistemological rigor and methodological clarity, aiming to transform public health questions through structural explanation. It notes her avoidance of prescriptive reforms, emphasizing intellectual retooling over direct interventions. For PHL, ChatGPT praises its actionable strategies, such as participatory budgeting, cooperative care models, and community organizing, which operationalize liberation as praxis. It highlights PHL’s explicit calls for redistribution and institutional redesign as mechanisms for health equity.
Both interpretations agree that Krieger’s applications are primarily academic and policy-oriented, aiming to reform epidemiology through training and research. Grok 3’s critique of her limited community engagement aligns with ChatGPT’s observation that she prioritizes theory over action. PHL, as both emphasize, excels in practical applications, offering a blueprint for community-led interventions. Grok 3 provides specific examples (e.g., Washington, DC’s Comprehensive Plan), while ChatGPT focuses on PHL’s broader mechanisms like solidarity economies. PHL’s praxis bridges theory and action, making it more immediately applicable to marginalized communities. Krieger’s work lays a theoretical foundation, but PHL’s hands-on approach better meets the urgent need for tangible change.
Grok 3 acknowledges Krieger’s inclusivity through her use of intersectionality and decolonization, which center marginalized experiences, but notes her academic perspective limits direct community engagement (Krieger, 2024, p. 334). Her “embodied truths” concept respects lived experiences but analyzes them through data rather than narratives. PHL, Grok 3 argues, prioritizes community voices, with Black women and public housing leaders as co-authors, grounding the framework in personal narratives like the Washington, DC lead crisis (Williams et al., 2022, pp. 2, 10). PHL’s horizontal integration amplifies marginalized voices in agenda-setting.
ChatGPT similarly notes Krieger’s engagement with justice through critical theory but emphasizes her focus on scientific rigor over community narratives. It describes PHL as foregrounding liberation through abolitionist and Indigenous frameworks, directly engaging community organizing to amplify marginalized voices. ChatGPT highlights PHL’s critique of mainstream public health for coopting social justice language without structural change.
Both interpretations concur that Krieger’s inclusivity is theoretical, rooted in frameworks like intersectionality, but lacks direct community involvement. PHL, as both emphasize, is deeply community-centered, with Grok 3 detailing its authorship by Black women and public housing leaders, and ChatGPT noting its alignment with grassroots movements. PHL’s liberation safe spaces and community autonomy (Williams et al., 2022, p. 12) ensure that interventions reflect lived experiences, contrasting with Krieger’s more detached, data-driven approach. PHL’s inclusivity aligns more closely with health justice principles of empowerment and self-determination.
Both Grok 3 and ChatGPT prefer Williams et al.’s PHL manuscript, though their rationales differ slightly. Grok 3 emphasizes PHL’s actionable, community-driven praxis, transdisciplinary scope, cultural specificity, inclusivity, and responsiveness to urgent global challenges like climate crises and health inequities. ChatGPT prioritizes PHL’s actionability, transdisciplinary reach, political clarity, and equity as praxis, arguing that it merges theory with liberatory action to meet the moment’s urgency.
This essay endorses Williams et al. (2022) as the preferred manuscript, aligning with both interpretations but synthesizing their insights to highlight PHL’s unique strengths:
Actionable Praxis: As both interpretations note, PHL translates theory into tangible interventions—e.g., community organizing, regulatory appeals, and vaccination campaigns (Williams et al., 2022, pp. 17-19). Grok 3’s examples and ChatGPT’s focus on mechanisms like participatory budgeting underscore PHL’s ability to empower communities to disrupt inequity reproduction, unlike Krieger’s more theoretical focus.
Transdisciplinary Vision: PHL’s integration of political theory, African American philosophy, and community psychology (Williams et al., 2022, pp. 7-10) transcends epidemiology’s boundaries, as ChatGPT emphasizes. Grok 3’s highlighting of constructs like “illiberation” and “Gaze of the Enslaved” underscores PHL’s innovative approach, addressing health inequities holistically.
Cultural and Historical Specificity: Grok 3’s emphasis on PHL’s African American liberation philosophy and historical trauma (Williams et al., 2022, pp. 9-10) complements ChatGPT’s focus on its decolonial and abolitionist roots. This specificity ensures relevance to communities disproportionately affected by inequities, contrasting with Krieger’s broader, less culturally grounded approach.
Community Empowerment: Both interpretations praise PHL’s inclusivity, with Grok 3 detailing its community authorship and ChatGPT noting its grassroots alignment. PHL’s liberation safe spaces and horizontal integration (Williams et al., 2022, pp. 5, 12) prioritize marginalized voices, aligning with health justice’s emphasis on self-determination.
Urgency and Relevance: In 2025, amid climate crises, political polarization, and persistent health disparities, PHL’s proactive, multi-pronged strategy—combining legal, social, and political tools—addresses these challenges more directly than Krieger’s call for theoretical reform, as both interpretations argue.
Krieger’s ecosocial theory is a landmark contribution, offering unmatched analytical depth and biological-ecological integration, as both interpretations acknowledge. Its applications to diverse issues (e.g., racism, climate change) demonstrate versatility (Krieger, 2024, p. 335). However, its academic focus, limited community engagement, and cautious approach to action, as noted by Grok 3 and ChatGPT, make it less immediately transformative. Integrating Krieger’s multilevel analysis with PHL’s praxis could enhance PHL’s explanatory power, but alone, Krieger’s work is slower to effect systemic change.
Krieger (2024) and Williams et al. (2022) both challenge reductive public health paradigms, prioritizing structural determinants to improve people’s health and advance health justice. Krieger’s ecosocial theory provides a rigorous, theoretically rich framework for understanding health inequities, while PHL offers a transdisciplinary, community-driven vision for systemic transformation. Synthesizing Grok 3’s and ChatGPT’s interpretations, this essay endorses PHL as the preferred manuscript for its actionable praxis, cultural specificity, inclusivity, and alignment with the urgent needs of 2025. PHL’s ability to merge theory with liberatory action—through community organizing, policy advocacy, and novel constructs like liberation and illiberation—makes it a bold, comprehensive response to health inequities. Future public health efforts could benefit from combining PHL’s practical strategies with Krieger’s analytical rigor to create a holistic, equitable paradigm that both explains and transforms the conditions shaping population health.
Comparative Analysis of Krieger (2024) and Williams et al. (2022) on Improving People’s Health and Advancing Health Justice
Both Nancy Krieger’s Theorizing Epidemiology, the Stories Bodies Tell, and Embodied Truths: A Status Update on Contending 21st Century Epidemiological Theories of Disease Distribution (2024) and Christopher Williams et al.’s Public Health Liberation - An Emerging Transdiscipline to Elucidate and Transform the Public Health Economy (2022) offer profound frameworks for understanding and addressing health inequities to improve population health and advance health justice. While both manuscripts share a commitment to tackling persistent health disparities and challenging dominant paradigms, they diverge in their theoretical foundations, methodologies, and practical implications. This essay compares the two works across key dimensions—conceptual frameworks, engagement with social and structural determinants, practical applications, and inclusivity of community perspectives—before arguing that Williams et al.’s manuscript is the preferred approach due to its transformative, community-centered, and transdisciplinary vision, which better aligns with the urgent need for actionable and equitable change in public health.
Krieger (2024) provides a critical review of 21st-century epidemiological theories of disease distribution, emphasizing the tension between dominant biomedical and lifestyle theories and emerging social epidemiological alternatives, particularly her ecosocial theory. The manuscript is grounded in a rigorous academic analysis, tracing the historical and theoretical evolution of epidemiology. Krieger’s ecosocial theory posits that health outcomes are “emergent embodied phenotypes” shaped by societal, ecological, and biological interactions across multiple levels and timescales (Krieger, 2024, p. 335). This framework integrates four core constructs: embodiment, pathways of embodiment, cumulative interplay of exposure, susceptibility, and resistance, and agency and accountability (Krieger, 2024, p. 336). These constructs aim to reveal “embodied truths” about health inequities, linking population health patterns to structural injustices like racism, sexism, and economic inequality.
Krieger’s approach is systematic and theoretically rich, drawing on a vast literature base (nearly 2,500 references) to critique the dominance of individualistic paradigms like precision medicine and lifestyle medicine, which focus on genomics and personal behaviors while sidelining societal context (Krieger, 2024, pp. 332-333). She advocates for social epidemiological theories—such as social determinants of health (SDOH), political economy of health, and Latin American social medicine—that explicitly address power, politics, and structural drivers. Her analysis is particularly strong in its critique of depoliticized frameworks, such as the SDOH’s occasional reduction to individualized risk factors, and its call for a renewed focus on political ecology to address climate and environmental crises (Krieger, 2024, pp. 334, 339).
Williams et al. (2022) introduce Public Health Liberation (PHL) as a transdisciplinary framework aimed at accelerating health equity through a novel concept: the “public health economy.” This economy encompasses the dynamic interplay of economic, political, and social drivers that reproduce health inequities (Williams et al., 2022, p. 4). PHL integrates five components—philosophy, theories, praxis, research, and training—synthesizing diverse traditions from African American emancipatory thought, political theory, sociology, and community psychology. Central to PHL is the principle of “liberation,” a mindset and practice that empowers communities to overcome “illiberation” (internalized oppression or fear) and engage in collective action (Williams et al., 2022, pp. 11-13). The manuscript proposes new constructs like the “Gaze of the Enslaved,” “Morality Principle,” and “Theory of Health Inequity Reproduction” (THIR) to guide ethical research and practical interventions (Williams et al., 2022, pp. 10, 14).
Unlike Krieger’s focus on epidemiological theory, PHL is explicitly transdisciplinary, rejecting the silos of traditional public health. It critiques the “anarchy” of the public health economy—its fragmentation and lack of governing principles—and proposes horizontal and vertical integration to include marginalized voices and expand the scope of public health interventions (Williams et al., 2022, pp. 5-6). The manuscript’s philosophical grounding in African American liberation thought and its emphasis on historical trauma provide a culturally specific lens that contrasts with Krieger’s broader, more universalist approach.
Comparison: Krieger’s framework is deeply rooted in epidemiology, offering a sophisticated theoretical lens that bridges biology, society, and ecology. Her ecosocial theory is particularly adept at explaining how structural injustices manifest in health outcomes, making it a powerful tool for academic research and policy analysis. However, its academic tone and focus on theory may limit its accessibility to non-specialists. Williams et al., by contrast, prioritize a transdisciplinary, community-driven approach that is less concerned with refining epidemiological methods and more focused on transforming the systems that perpetuate inequity. PHL’s public health economy concept is less biologically grounded than ecosocial theory but more expansive in its integration of diverse disciplines and its emphasis on actionable change. While Krieger’s work excels in analytical depth, PHL’s framework is more dynamic and inclusive, prioritizing community agency and cultural relevance.
Both manuscripts emphasize the critical role of social and structural determinants in shaping health inequities, but they approach these determinants differently.
Krieger (2024) meticulously documents the rise of social epidemiological theories that challenge the biomedical and lifestyle paradigms. She highlights the growth of SDOH, political and commercial determinants of health, and Latin American social medicine, which focus on power, politics, and economic systems (Krieger, 2024, pp. 334-335). Her critique of precision medicine and lifestyle medicine underscores their failure to address structural issues like racism and economic inequality, which are central to health disparities (Krieger, 2024, pp. 332-333). Krieger also integrates intersectionality and decolonization frameworks, acknowledging their contributions to analyzing intertwined injustices across race, gender, class, and colonialism (Krieger, 2024, p. 334). Her ecosocial theory explicitly links these determinants to biological embodiment, offering a multilevel model that connects macro-level societal structures to micro-level physiological outcomes.
However, Krieger notes the ongoing marginalization of social epidemiological theories, as evidenced by their low funding and publication rates compared to biomedical approaches (Krieger, 2024, p. 332, Table 1). She argues that this dominance reflects a broader failure to train epidemiologists in these theories, perpetuating a focus on individual-level interventions (Krieger, 2024, pp. 337-338). Her call for a “wake-up call” emphasizes the need to engage with political ecology and structural drivers to address global challenges like climate change and persistent health inequities (Krieger, 2024, p. 339).
Williams et al. (2022) frame social and structural determinants within the public health economy, which they describe as a competitive, anarchic system where resources and power are unequally distributed (Williams et al., 2022, p. 4). Their THIR model identifies four components of inequity reproduction: social mobilization, constraints (e.g., regulations), economic incentives, and a constant of entrenched structural inequity (Williams et al., 2022, p. 14). PHL’s focus on historical trauma, particularly from slavery and Jim Crow, grounds its analysis in the lived experiences of Black Americans, emphasizing how past injustices continue to shape present disparities (Williams et al., 2022, pp. 9-10). The manuscript also critiques the deracialized and dehistoricized nature of terms like “structural vulnerability,” arguing that they fail to capture the specificity of racialized harm (Williams et al., 2022, p. 5).
PHL’s approach is notably proactive, advocating for interventions like legal action, community organizing, and policy advocacy to disrupt inequity reproduction (Williams et al., 2022, pp. 17-18). The manuscript’s case studies of lead-contaminated water crises in Flint and Washington, DC, illustrate how systemic failures—rooted in environmental racism and institutional negligence—perpetuate health disparities, underscoring the need for a transdisciplinary response (Williams et al., 2022, p. 4).
Comparison: Both manuscripts prioritize structural determinants, but Krieger’s approach is more academically oriented, focusing on refining epidemiological theory to better account for these factors. Her ecosocial theory provides a robust framework for understanding how societal structures shape health, but it remains largely within the confines of epidemiology. Williams et al. take a broader, more applied approach, situating structural determinants within a dynamic public health economy that demands collective action. PHL’s emphasis on historical trauma and racialized experiences offers a more culturally specific lens, while its transdisciplinary scope allows for a wider range of interventions. Krieger’s work is stronger in its biological and ecological integration, but PHL’s focus on community-led solutions and systemic transformation better addresses the urgency of structural change.
Krieger (2024) advocates for integrating social epidemiological theories into research, practice, and pedagogy to improve population health and advance health justice. She calls for explicit training in these theories, arguing that their absence in curricula and guidelines like STROBE hinders rigorous research (Krieger, 2024, pp. 337-338). Her ecosocial theory has been applied to diverse issues, including cancer, reproductive health, racism, and climate change, demonstrating its versatility (Krieger, 2024, p. 335). Krieger emphasizes the need for research that reveals “embodied truths” to hold accountable those responsible for health inequities, supporting legal and policy interventions (Krieger, 2024, p. 340). However, the manuscript offers few concrete examples of community-based applications, focusing instead on academic and policy-level implications.
Williams et al. (2022) prioritize praxis—applied liberation through community-led interventions—as a core component of PHL. The manuscript provides tangible examples, such as the authors’ advocacy against environmental racism, housing displacement, and gentrification in Washington, DC (Williams et al., 2022, p. 3). Their work on the city’s Comprehensive Plan and vaccination campaigns during COVID-19 illustrates how PHL translates theory into action, involving community webinars, citizen research, and coalition-building (Williams et al., 2022, pp. 18-19). PHL’s emphasis on liberation safe spaces and overcoming illiberation empowers communities to advocate for themselves, reducing reliance on external institutions (Williams et al., 2022, pp. 12-13). The manuscript also proposes training programs to equip communities and students with skills in law, policy analysis, and community organizing, ensuring sustainable change (Williams et al., 2022, p. 19).
Comparison: Krieger’s practical applications are primarily academic and policy-oriented, aiming to reform epidemiological training and research to better address health inequities. While theoretically robust, her approach lacks detailed guidance on community engagement. Williams et al. excel in practical applications, offering a blueprint for community-led interventions that directly confront systemic inequities. PHL’s praxis-oriented approach, rooted in real-world advocacy, makes it more immediately actionable, particularly for marginalized communities seeking to transform their health outcomes.
Krieger (2024) acknowledges the importance of community perspectives through her discussion of intersectionality and decolonization, which center the experiences of marginalized groups (Krieger, 2024, p. 334). However, the manuscript is written from an academic perspective, with limited direct engagement with community voices. Krieger’s focus on “embodied truths” implies a respect for lived experiences, but these are primarily analyzed through epidemiological data rather than community narratives (Krieger, 2024, p. 335). Her work is less explicit about how communities can actively shape research or interventions, reflecting a top-down approach.
Williams et al. (2022) place community perspectives at the heart of PHL, with a majority of Black women authors and public housing leaders contributing to the manuscript (Williams et al., 2022, p. 2). The inclusion of personal narratives, such as the trauma of the Washington, DC lead crisis, grounds the framework in lived experiences (Williams et al., 2022, p. 10). PHL’s horizontal integration explicitly calls for amplifying marginalized voices in public health agenda-setting, critiquing the exclusionary practices of major health institutions (Williams et al., 2022, p. 5). The manuscript’s emphasis on liberation safe spaces and community autonomy ensures that interventions are driven by those most affected by inequities (Williams et al., 2022, p. 12).
Comparison: Williams et al. demonstrate a stronger commitment to inclusivity, prioritizing the voices and agency of marginalized communities, particularly Black Americans and women. Krieger’s work, while inclusive in its theoretical scope, remains academically oriented and less engaged with community-driven processes. PHL’s community-centered approach aligns more closely with health justice principles, which emphasize empowerment and self-determination.
While both manuscripts offer compelling visions for improving people’s health and advancing health justice, Public Health Liberation by Williams et al. (2022) is the preferred approach due to its transformative, community-centered, and transdisciplinary framework. Several factors support this preference:
Actionable and Community-Driven: PHL’s emphasis on praxis and liberation empowers communities to directly address inequities, as evidenced by its real-world applications in Washington, DC. Unlike Krieger’s primarily academic focus, PHL provides a roadmap for communities to navigate the public health economy, making it more accessible and relevant to non-specialists.
Transdisciplinary Scope: By integrating diverse disciplines—political theory, sociology, African American philosophy, and community psychology—PHL transcends the limitations of epidemiology, offering a holistic approach that addresses the complexity of health inequities. Krieger’s ecosocial theory, while innovative, remains within the epidemiological paradigm, which may constrain its ability to effect systemic change.
Cultural and Historical Specificity: PHL’s grounding in African American liberation thought and historical trauma provides a culturally relevant lens that resonates with communities disproportionately affected by inequities. Krieger’s universalist approach, while inclusive, lacks the same depth of cultural specificity, which is critical for addressing racialized health disparities.
Inclusivity and Empowerment: PHL’s horizontal integration and liberation safe spaces prioritize the voices and agency of marginalized groups, aligning with health justice principles. Krieger’s work, while theoretically inclusive, does not emphasize community empowerment to the same extent, risking a top-down approach.
Response to Urgency: In an era of escalating climate crises, political polarization, and persistent health inequities, PHL’s proactive, multi-pronged strategy—combining legal, social, and political interventions—better addresses the urgency of systemic transformation. Krieger’s call for theoretical reform, while necessary, is slower to translate into immediate action.
However, Krieger’s work is not without merit. Her ecosocial theory provides a rigorous, biologically grounded framework that complements PHL’s broader approach. Integrating Krieger’s multilevel analysis with PHL’s praxis could enhance the latter’s ability to link structural determinants to physiological outcomes. Nonetheless, PHL’s focus on community agency, cultural relevance, and systemic change makes it the more compelling framework for advancing health justice in the current global context.
Both Krieger (2024) and Williams et al. (2022) offer critical insights into improving people’s health and advancing health justice, challenging the dominance of individualistic paradigms and emphasizing structural determinants. Krieger’s ecosocial theory excels in its analytical depth and integration of biological and ecological factors, making it a vital tool for academic research and policy reform. However, Williams et al.’s PHL framework is the preferred approach due to its transdisciplinary, community-centered, and actionable vision, which empowers marginalized communities to transform the public health economy. By prioritizing liberation, inclusivity, and praxis, PHL not only elucidates the root causes of health inequities but also provides a blueprint for collective action, making it uniquely suited to address the urgent challenges of our time. Future efforts could benefit from synthesizing PHL’s practical strategies with ecosocial theory’s analytical rigor to create a comprehensive, equitable public health paradigm.
Based on a full review and comparison of the two manuscripts — Nancy Krieger’s “Theorizing Epidemiology: The Stories Bodies Tell and Embodied Truths – A Status Update on Contending 21st Century Frameworks” and the co-authored article “Public Health Liberation: An Emerging Transdiscipline to Elucidate and Affect the Public Health Economy” — this essay offers a detailed comparative analysis on how each addresses the dual goals of improving people’s health and advancing health justice. It concludes with a reasoned preference for the manuscript that more effectively integrates theory with action toward health equity.
1. Krieger’s “Theorizing Epidemiology”
This work is a comprehensive, deeply theoretical, and historically grounded examination of various epidemiological frameworks that inform contemporary public health. Nancy Krieger surveys five major paradigms: biomedical, lifestyle, psychosocial, social determinants of health (SDOH), and ecosocial. Her analysis investigates how these frameworks conceptualize the causes of disease, the embodiment of inequality, and the potential for structural transformation.
2. “Public Health Liberation” Manuscript
This newer and more prescriptive paper introduces “Public Health Liberation” (PHL) as a transdisciplinary framework that critiques the public health economy as a site of both health production and political struggle. The manuscript proposes new epistemologies rooted in feminist, abolitionist, decolonial, and Indigenous worldviews. It positions health justice as a liberatory practice that challenges capitalism, white supremacy, and state violence.
Krieger’s Approach
Krieger emphasizes that improving people’s health cannot be meaningfully addressed without interrogating the social production of disease. Her ecosocial theory, developed over decades, links biology and political economy through the concept of “embodiment” — the idea that social and ecological conditions literally shape biological outcomes. While the biomedical and lifestyle models isolate individual bodies from their contexts, Krieger’s ecosocial theory provides a systemic approach that identifies upstream determinants and power dynamics.
She criticizes frameworks that medicalize health without addressing root causes such as labor conditions, racism, housing, and environmental exposures. While she does not prescribe specific interventions, she demands epistemological rigor and historical accountability as prerequisites for genuine public health progress.
PHL’s Approach
The Public Health Liberation paper takes a more explicit stance on health as a political project. It conceptualizes health improvement not only as a biomedical or behavioral issue but as a process of dismantling oppressive structures. The manuscript discusses the “public health economy” as a dynamic system where health is both commodified and contested. The authors argue that to improve health, public health must actively resist privatization, austerity, and carceral logics.
The paper goes further than Krieger’s in prescribing transformation: it advocates for participatory budgeting, cooperative models of care, and solidarity economies. These proposals operationalize liberation not just as theory but as praxis — bridging epistemic critique with tangible mechanisms of change.
Krieger’s Framing
Krieger engages health justice primarily through critical theory and historical contextualization. She shows how different frameworks either obscure or illuminate the political dimensions of health inequities. Her ecosocial framework is deeply invested in justice but emphasizes scientific rigor, historical depth, and epistemological integrity over activist language. Her contribution lies in the intellectual retooling of epidemiology to account for power, history, and embodiment.
Krieger avoids oversimplified calls for action and instead demands that public health theory itself be just — that is, accountable to the lives and bodies it studies. She promotes justice through structural explanation and methodological clarity, seeking to transform the questions we ask in public health.
PHL’s Framing
In contrast, the PHL manuscript foregrounds liberation as a guiding principle and goal. It defines health justice as a struggle against the "public health economy" — the structural arrangements that determine who lives, who dies, and who profits. The authors invoke abolitionist frameworks, Indigenous sovereignty, and community control not as metaphors, but as foundations for a new discipline. They critique mainstream public health for co-opting social justice language without changing institutional structures.
The manuscript’s strength lies in its direct engagement with political theory and community organizing. It advances health justice not only as a moral imperative but as a political economy in practice. This makes its justice orientation more explicit, more actionable, and more aligned with grassroots movements.

Both manuscripts challenge reductive understandings of health and call for structural transformation. But PHL pushes the envelope further by demanding radical political and economic change — not just better frameworks for describing health inequities, but mechanisms to dismantle the systems that produce them.
While both manuscripts offer profound insights, “Public Health Liberation” is the preferred work in terms of evaluating how to both improve people’s health and advance health justice.
The reasons are:
Actionability: PHL moves beyond critique to offer concrete strategies rooted in community control, abolition, and decommodification. These are vital steps toward meaningful, material improvements in health.
Transdisciplinary Reach: It broadens the conversation beyond public health’s traditional boundaries, enabling more holistic and liberatory frameworks. This reflects the realities of how health is shaped in practice — through intersecting institutions of governance, labor, and care.
Political Clarity: PHL directly confronts the political economy of health, identifying power as the central determinant of health inequity. While Krieger theorizes this expertly, PHL organizes around it.
Equity as Praxis: Where Krieger’s ecosocial theory offers an invaluable lens, PHL turns that lens into a tool of organizing, budgetary reallocation, and institutional redesign.
Nancy Krieger’s “Theorizing Epidemiology” remains a landmark contribution for understanding the theoretical foundations of population health and injustice. It offers unmatched clarity in distinguishing and evaluating epidemiological frameworks. However, the Public Health Liberation manuscript is more effective in merging theory with praxis, offering a bolder and more comprehensive vision for structural change and health equity. As public health continues to reckon with colonialism, racial capitalism, and ecological collapse, frameworks that integrate critical theory with liberatory action will be indispensable. In that sense, PHL is not just a critique, but a call — one that meets the urgency of the moment.
