Has the US exported its obesity epidemic to Mexico?
Research has found that 20% of the increase in obesity in Mexico can be explained by exposure to US food exports.
Mexico has seen a tremendous increase in obesity and diabetes over the past decades, while trade in food and beverages with the US soared. This begs the question: is there a causal effect of trade in foods on the prevalence of obesity in Mexico? The infographic below presents the key research findings.
The research is published in the leading Journal of International Economics. For the study, the researchers matched data on anthropometrics (body measurements) of Mexican women, data on trade in Mexican food imports from the US and data on Mexican household food expenditure.
WHO warning - we are facing a global obesity epidemic
The findings point to a positive and significant effect of exposure to US food exports on obesity prevalence thereby demonstrating how globalization, through food, can affect the health of populations in other countries.
This is pertinent in light of recent warnings from the World Health Organization (WHO) that we are facing a global obesity epidemic ('globesity'). The findings of this study may be relevant to fellow academics, policy-makers and practitioners interested in (over)nutrition, public health and international trade.
The research was conducted by Dr Matthias Rieger from ISS, together with Dr Osea Giuntella (Assistant Professor of Economics at the University of Pittsburgh) and Dr Lorenzo Rotunno (Assistant Professor of Economics at Aix-Marseille University).
