The contribution of ethnography to epigenomics research: toward a new bio-ethnography for addressing health disparities

This article describes ethnography as a research method and outlines how it excels in capturing the salient experiences of individuals among diverse communities in their own words. We argue that the integration of ethnographic findings into epigenomics will significantly improve disparities-focused study designs within environmental epigenomics by identifying and contextualizing the most salient dimensions of the 'environment' that are affecting local communities. Reciprocally, epigenetic findings can enhance anthropological understanding of human biological variation and embodiment. We introduce the term bio-ethnography to refer to research designs that integrate both of these methodologies into a single research project. Emphasis is given in this article, through the use of case studies, to socially disadvantaged communities that are often under-represented in scientific literature. The paper concludes with preliminary recommendations for how ethnographic methods can be integrated into epigenomics research designs in order to elucidate the manner in which disadvantage translates into disparities in the burden of illness.
