[Overweight and obesity in children and adolescents, 2016 Halfway National Health and Nutrition Survey update].

OBJECTIVE

To estimate recent overweight and obesity prevalences in Mexican population under 20 years from Halfway National Health and Nutrition Survey (Ensanut MC 2016).

MATERIALS AND METHODS

Ensanut MC 2016 is a probabilistic national survey which gives representative information from national, regional and rural/urban levels. BMIz was estimated through weight and height, then it was classified into overweight risk or overweight or obesity ac¬cording to WHO growth reference standards. Association between overweight and sociodemographic information was analyzed through logistic regression models.

RESULTS

Overweight-obesity prevalence was 5.1% in girls and 6.5% in boys<5y, 32.8% in girls and 33.7% in boys 5-11y, and 39.2% in female adolescents and 33.5% in male adolescents. Female adolescents from rural localities increased overweight-obesity prevalence from 27.7% in 2012 to 37.2% in 2016.

CONCLUSIONS

Overweight-obesity increased in girls and females, mainly from rural areas. Strategies focued in containing this phenomenon are encouraged to implement in this context.
