Bommer et al. (2017) estimated that in 2015 the total global cost of diabetes was US$ 31trillion, or 1,8% of the global GDP. The authors recognized the fact as a global economic burden that is transversal from high-income to poorer world regions.The WHO diabetes report (2016) associates this increase with population growth and ageing, but also with overweight and obesity prevalence, and thus, emphasises the need to prioritise actions to prevent them as early as before birth and early childhood. It stresses the need of a coordinated multicomponent intervention of all stakeholders, and it also recommends addressing key gaps in the diabetes knowledge base, as well as the evaluation of innovative programmes intended to change behaviour.Obesity, which increases the likelihood of diabetes, hypertension, coronary heart disease, stroke and certain kinds of cancer, has seen its prevalence nearly doubled worldwide since the 80’s. In 2013, 11% of adult men and 15% of women were obese, and more than 42 million children under 5 were overweight (WHO, 2014a).Overweight and obesity affects all social, cultural and economic groups in every corner of the world and in 2010 it was responsible for 2,8 million annual deaths (Roberto et al., 20). This epidemic is considered to have the potential to negate many of the healthcare benefits that have been contributing for the increase of lifetime expectancy. It is especially worrying among children, and it’s believed to be the result of changes in food availability and type and, at the same time, of a decline in physical activity (WHO, 2016a).
