The biohabitus of scarcity: bio-social dispositions and the "obesity epidemic" in Mexico.

Abstract

In this article, we explore the potential of Warin etal.'s concept of biohabitus (a set of embodied biological and social dispositions) as a conceptual tool for the understanding of mechanisms behind the "obesity epidemic." Elaborating on this concept, we argue that a context of food scarcity gives rise to a biohabitus geared to energy-saving, expressed in both biological (the thrifty genotype/phenotype hypotheses) and symbolic dispositions (Bourdieu's "taste of necessity"), and the interaction between this type of biohabitus and changes in the food-related environment results in increased body mass index. We exemplify the use of this framework by applying it to the case of Mexico, a middle-income Latin American country with one of the highest prevalences of obesity worldwide. The example shows how the concept of biohabitus can help researchers move beyond disciplinary explanations, towards a more complex understanding of the conjunction of social and biological processes that result in differential patterns of health and disease.
