The dynamic of obesity from a systemic approach

Abstract

In this thesis, I propose a systemic framework to study the obesity dynamics. Obesity can be studied through different levels of analysis; however, in this work, it was studied through two levels of analysis (country level and Individual level). At the country level, different investigations which have been developed to study the relationship between obesity, SES, and the country's economic development level suggest that obesity tends to transition towards the lower-SES population as the country's GNP increases. In this work, I propose a mathematical model that could be used to assess the nutritional transition by SES in LMICs. At the individual level, different studies have suggested that the hypothesis about the nutritional transition that some LLMICs are experiencing should be tested through comparisons of time trends of obesity in different SES groups of a Single population
