The historical evolution of social determinants of health (SDOH) has significantly influenced the field of preventive medicine. SDOH encompass the conditions in which individuals are born, grow, live, work, and age, and they are increasingly recognized as critical factors that shape health outcomes and health disparities across populations (Gard et al., 2020).
The World Health Organization (WHO) has played a pivotal role in framing health not merely as the absence of disease but as a state of complete physical, mental, and social well-being, a definition that has guided public health initiatives since 1946 (Abnousi et al., 2019). This broader understanding of health has led to a growing recognition that addressing social factors is essential for effective preventive medicine. Historically, the focus on SDOH can be traced back to the mid-20th century when public health efforts began to emphasize the importance of social and economic factors in health outcomes.
The WHO’s Commission on Social Determinants of Health, established in 2005, further catalyzed this movement by highlighting the need for comprehensive strategies that address the root causes of health inequities (Galea et al., 2020). This shift towards a more holistic view of health has prompted researchers and practitioners to explore how social, economic, and environmental factors intersect with individual behaviors and biological predispositions to influence health (Amador, 2023; Braveman et al., 2011). The evolution of SDOH research has also highlighted the importance of “upstream” interventions—those that target systemic and structural factors—over “downstream” measures that focus solely on individual behaviors (Carey & Crammond, 2015). This perspective is crucial for preventive medicine, as it underscores the need for policies and programs that address the broader social context in which health behaviors occur. For instance, interventions aimed at improving housing stability, access to nutritious food, and educational opportunities have been shown to have a more profound impact on health outcomes than traditional medical interventions alone (Taylor et al., 2016; Nichols & Taylor, 2018). Moreover, the historical context of SDOH has revealed persistent challenges in integrating these factors into health policy and practice.
Despite the growing body of evidence supporting the significance of SDOH, there remains a gap between research and implementation. Many health systems continue to prioritize clinical care over social interventions, often due to entrenched interests and a lack of sustainable funding for SDOH initiatives (Irwin & Scali, 2007; Bambra et al., 2009). This disconnect highlights the need for a paradigm shift in how health care providers and policymakers conceptualize health and wellness, moving beyond a purely medical model to one that incorporates social determinants as fundamental components of health care delivery (Galea, 2022).
In recent years, the COVID-19 pandemic has further illuminated the critical role of SDOH in shaping health disparities. The pandemic disproportionately affected marginalized communities, revealing how factors such as income inequality, access to health care, and housing instability can exacerbate health risks (Amador, 2023; Brady, 2020). This has led to renewed calls for integrating SDOH into preventive medicine strategies, emphasizing the need for a comprehensive approach that addresses both individual and systemic factors (Larson et al., 2023; Silverstein et al., 2019).
The historical evolution of SDOH has also prompted a re-examination of the role of health care providers in addressing these determinants. Physicians and other health professionals are increasingly being called upon to recognize and respond to the social contexts of their patients’ lives, which requires not only clinical skills but also cultural competence and an understanding of the broader social landscape (Kucherepa & O’Connell, 2021; Schwenk, 2020). This shift necessitates a transformation in medical education and training, ensuring that future health care providers are equipped to address the social determinants of health effectively.
In conclusion, the historical perspective on social determinants of health reveals a complex interplay between social, economic, and environmental factors and health outcomes. The evolution of this field has underscored the importance of addressing SDOH in preventive medicine, highlighting the need for systemic changes that prioritize health equity. As the understanding of SDOH continues to evolve, it is imperative that health care systems and providers adapt their approaches to incorporate these critical factors into their practice, ultimately leading to improved health outcomes for all populations.
