Epigenetics and Social Determinants of Health

Social Determinants of Health

“The social determinants of health are the conditions in which people are born, grow, live, work and age. These circumstances are shaped by the distribution of money, power and resources at global, national and local levels. The social determinants of health are mostly responsible for health inequities – the unfair and avoidable differences in health status seen within and between countries.”

– From the World Health Organization

From the Oxford English Dictionary

  • Diet:  The kinds of food that a person, animal, or community habitually eats.  ‘a vegetarian diet’
  • Epigenetics:  The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself.  ‘epigenetics has transformed the way we think about genomes’
  • Disparity:  A great difference.  ‘economic disparities between different regions of the country’

Epigenetics, Social Determinants of Health and the Social Ecological Model

Keep the social determinants of health in mind while reading Diet, the Gut Microbiome, and Epigenetics” by Hullar et. Al.  The field of epigenetics is in its infancy.  Consider how access to certain foods and environmental conditions may increase or decrease an individual’s cancer risk.

Remember the social history session from immersion?  When you last took a social history was it in the context of the social ecological model?  Think about your last patient encounter.  Place that patient within the social ecological model.  How has their life and health been influenced by individual, interpersonal, organizational, community and policy level interactions?

Racial Disparities in Cancer Treatment and Outcomes

Not that “Disparities in Cancer Care and Outcomes” was published in the Journal of the American College of Surgery.  This article “explores radical disparities in the context of cancer surgery.”  Take note of Figure 1.  Do you think the steps present in this figure might help you explore disparities in outcomes in other conditions?  How is it similar to the social ecological model?  How is it different?
