Les enjeux socioéconomiques de la transition nutritionnelle au Mexique

Abstract : In the context of globalization and urbanization, the rapid industrialization of emerging countries drives on deep transformations in lifestyles and consumption habits. Hence, an intense process of nutrition transition occurs: nutritional deficiencies and infectious diseases decline, but persist, while obesity and comorbidities reach endemic levels. Facts point that nutrition transition process is not homogenous at the worldwide level and within a given society. Such heterogeneity can be explained by the presence of social, economic and cultural factors. In order to explore the relationship between these factors and obesity, the study focuses on Mexico, an emerging country which has fully begun its nutrition transition process since the 1980s’. First, I analyze the socioeconomic determinants of body-mass and show that weight gain particularly affects a lower middle class on the verge of poverty. Both the lack of education and earning an extra income appear to be risk factors for lower social categories. Furthermore, I study the effects of body-mass on educational and occupational failures. The findings uncover mechanisms by which both obesity and central adiposity reduce one’s capacity to climb the socioeconomic ladder. Finally, I assess the impact of the Mexican conditional cash transfers’ program on adult body-mass. The results suggest that social programs constitute an adequate intervention to break the vicious cycle of poverty and obesity. Since the conditionalities counterbalance negative externalities from an extra income, such programs significantly improve health and nutritional knowledge and behaviors of participants. To conclude, the thesis dissertation emphasizes the necessity for policy makers to simultaneously take into account social, economic, and cultural aspects of obesity.
