Impact de l'obésité sur les structures sociales et impact des structures sociales sur l'obésité

Abstract : I will propose a theoretical framework (conceptualization and formalization) which seeks to model obesity as a process of transformation of one's own body determined by individual (physical and psychological), inter-individual (relational, relationship between the individual and others) and socio-cultural factors (environmental, relationship between the individual and his milieu). Individual and inter-individual factors are tied to each other in a socio-cultural context whose impact is notably related to the visibility of any body being exposed on the public stage in a non-contingent way. To investigate obesity in this multifactorial manner, this paper is divided in two main parts. First, I take into account these inseparable factors to analyze the impact through time that obese individual transformation may have on the social structure. With this aim, I develop a network model in which individual interactions are in part due to homophilic selection/deselection, i.e. preferential attachment and detachment of inter-individual links according to characteristics of the individuals involved. Homophily is here defined as the tendency of an individual to create links with other individuals sharing similar attributes with him and to cut links with other dissimilar individuals. Homophily suggests that individuals tend to interact with those who resemble them. Second, and reciprocally, I study the role which could be played by the structure of the social fabric in the increase and current development of obesity. I evaluate the impact of micro level (i.e : relations between individuals) as well as the impact of meso level (i.e : relations between districts) and between macro level (i.e :countries). This approach highlights the necessity to integrate the dynamics of each scale to better understand the evolution of the pathology. With this aim, I use two stochastic models : epidemiological compartmental model and individual centered network model, considering three influences : exogenous heterogeneous (individual- cultural), exogenous homogeneous (individual-social) and endogenous (individual-individual). All together, this investigation of obesity will allow me to investigate the social and cultural dimension involved in being and transforming one's body.
