CALDERA ZAMORA, Iván Alejandro et al. Predictors of risk eating behaviors in high school students. Rev. Mex. de trastor. aliment [online]. 2019, vol.10, n.1, pp.22-31. ISSN 2007-1523.  https://doi.org/10.22201/fesi.20071523e.2019.1.519.

The main objective of this study was to identify sociodemographic and psychosocial variables capable of predicting risk eating behaviors (REB) in high school students. Participants were 988 adolescents (541 women and 447 men) between 14 and 18 years of age (M = 16.79, SD = 1.50). In addition to the REB (Binge-purge, Compensatory behavior and Restriction), examined through the Brief Questionnaire on Risk Food Behaviors, the following psychosocial variables were also evaluated: family and friend support, school adjustment, victimization, suicidal ideation, academic stress, body dissatisfaction and depression; finally, the sociodemographic variables included were: sex, age, hours of sleep per day and hours dedicated to the Internet or social networks. Through three multiple linear regression analyzes, one for each REB (R2 = .36, .16 and .55, respectively; all with p < .001), different predictive variables could be identified, among which stood out the body dissatisfaction, the depression and sex (women). The identification of these variables can contribute to the improvement of prevention strategies in terms of REB and eating disorders among adolescents.
