This correlational descriptive study aimed to validate the predictive model of risk of developing eating behavior disorder in young people based on the measurement of variables such as eating behavior, body image dissatisfaction, body mass index, family functioning, and the use of criticism toward young people about their weight and the shape of their body, in young people and parents. The non-randomized sample of convenience included 208 participants, 104 of them were adolescents aged between 11 and 18 years, studying in different high schools, and 104 family members considered to be significant by the teenagers. EAT-26, ECA, Family APGAR, FEICS, and BMI were applied, all validated for the Colombian population. As a result of the multivariate analysis, it was found that the high risk of developing behavioral disorders in young people is related to high risk in their relatives; the article concludes that parents, in addition to playing a protective role, may represent a risk factor for the eating behavior of their children, given that children model their behavior on their parents from early childhood.
