Obesity determinants: A systematic review

For many diseases, research has shown a correlation between social organization and disease´s spread. Thus, some diseases that are not infectious such as obesity, have been declared by the World Health Organization as an epidemic. The aim of this paper, is to study obesity models and to investigate on obesity factors evoked in the literature. Therefore we realized a search of models using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach, then we exposed some of them using ODD protocol. As a result of this sysematic review, 106 studies were selected. Then, obesity determinants figured out were classified into environmental, psychological and behavioral, and biological factors.
