Background: The trend in the BMI values of US children has not been estimated very convincingly because of the absence of longitudinal data. Our object is to estimate time series of BMI values by birth cohorts instead of measurement years. Methods: We use five regression models to estimate the...

This paper proposes a theory for the social evolution of obesity. It considers a society in which individuals experience utility from consumption of food and non-food, the state of their health, and the evaluation of their appearance by others. The theory explains under which conditions poor...

Nutrition transitions are characterized by shifts in diet and activity levels that lead to changes in weight and body fatness over a relatively short time. Research has linked these nutritional shifts to socio-economic factors, including wealth and income. However, few studies have examined...

An age-structured model for childhood obesity at population level is fitted to empirical data in order to predict the proportion of overweighted and obese children in the 6-8 and 9-12 year old classes in the region of Valencia, Spain.

In this paper we extend a compartmental model to the case of a homogenous network epidemic model for a study of the dynamics of obese populations. The social epidemic network-based approach developed here uses different algorithms and points of views regarding the simulation of the dynamics of...
