Objective.

To analyze the evolution in prevalence of risky eating behaviors (REB) in Mexican adolescents between 2006 and 2018.

Materials and methods:

We employed data from Ensanut 2006 and 2018-19. We evaluated REB with the Brief Questionnaire of Risky Eating Behaviors, distinguishing between normative (recommended for obesity prevention) and non-normative (not recommended) REB. We analyzed the association between REB and indicators of the sociocultural environment of adolescents (socioeconomic level, urban/rural place of living.

Results:

The prevalence of normative REB changed from 11.9% (95%CI: 11.3-12.6) to 15.7% (95%CI: 15.0-16.5), and the prevalence of non-normative REB from 12.1 (95%CI: 11.4-12.9) to 21.9 (95%CI: 21.0-22.9). REB were more frequent among females, those with overweight or obesity, those in the higher socioeconomic levels, and in urban areas.

Conclusions:

REB are an important issue among adolescents, and preventive strategies are required.
