Objective:

To estimate the obesity prevalence among school-age children in Mexico and define possible risk-associated factors.

Materials and methods:

Data from National Health and Nutrition Survey (Ensanut 2018-19) was used. Information from 6 268 school-age children and 5 670 teenagers was obtained. Logistic regression models were estimated in order to study the relationship between overweight and obesity (OW+O) and sociodemographic variables, OW+O condition in their parents, health, dietary and healthy behaviors variables.

Results:

OW+O in school-age children and teenagers is associated with the presence of OW+O in their mothers (p<0.001), more time spent in front of a screen and belonging to a middle wealth conditions index; a negative association was found for dietary fiber consumption. In teenagers with obesity, the odds for depression showed an increase.

Conclusion:

It is important to identify the predisposing and risk factors and the causes behind obesity in children in order to design integral prevention strategies.
