Obesity represents one of the most important public health
challenges of the modern era. Projections for 2030 have estimated
that up to 2.16 billion and 1.12 billion adults will be
overweight and obese, respectively [1]. Yet, it has been recognised
that the economic, social and health consequences will
be greater for low- and lower-middle-income countries facing
nutritional transitions such as those in Northern
Africa, the Middle East, Asia and Latin America [2].
Several responses have been undertaken to counteract
this problem mainly through interventions that have
addressed modifiable factors - such as healthy eating and
physical activity [3-6]. Results nevertheless have been inconsistent
in the long term, partly due to a lack of commitment
and allocated resources from national levels for
evaluation and to guarantee their sustainability [7].
