Disordered eating in Mexican adolescents, 2006-2018

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 Ensa nut 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.
