To assess the validity and reliability of a questionnaire for the screening of risk eating behaviors. The questionnaire was applied to female high school students in Mexico City in October 2002, as well as to a sample of eating disorder patients seen at the Eating Disorders Unit of the National Institute of Psychiatry between September and December 2002. Statistical methods included internal consistency analysis (Cronbach's alpha) and factor and principal component analysis with oblique rotation. The cutoff point, sensitivity, specificity, and predictive values of the questionnaire were determined using 2 x 2 tables. The questionnaire showed a high reliability (alpha=0.83) and a three-factor structure with 64.7% of the total explained variance. A discriminant analysis showed that almost 90% of cases were correctly classified. This questionnaire is reliable and valid for assessing risk eating behaviors in the study population.

(1) Background: The importance of studying the health interventions used to prevent and treat overweight and obesity in school-aged children is imperative. This overview aimed to summarize systematic reviews that assess the effects of school-based, family, and mixed health interventions for preventing and treating overweight and obesity in school-aged children. (2) Methods: The Cochrane Collaboration methodology and PRISMA statement were followed. A search was conducted using terms adapted to 12 databases. Systematic reviews reporting interventions in children from six to 12 years old with an outcome related to preventing or treating obesity and overweight were included. Studies with pharmacological or surgical interventions and adolescents were excluded. (3) Results: A total of 15,226 registers were identified from databases and citation searching. Of those, ten systematic reviews published between 2013 and 2022 were included. After the overlap, 331 interventions for children between 6 and 12 years old were identified, and 61.6% involved physical activity and nutrition/diet intervention. Multicomponent intervention, combining physical activity with nutrition and behavioral change, school-based plus community-based interventions may be more effective in reducing overweight and obesity in children. (4) Conclusions: Plenty of interventions for childhood overweight and obesity aimed at prevention and treatment were identified, but there is a gap in the methodological quality preventing the establishment of a certain recommendation.

Determine the relationship between the variables of self-esteem (SE), body dissatisfaction (BD), and body mass index (BMI) in a continuum of risky eating behaviors (REB) that ranges from normal behavior to the risk of eating disorders (ED), thus facilitating early detection of adolescents with ED symptomatology and the degree to which such variables have an influence. A total of 1 982 young women aged 15-19 were selected through stratified random sampling. Self-esteem (Pope, McHale, and Craighead scale), body dissatisfaction (Stunkard's Figure Rating Scale), and body mass index were measured. A brief REB questionnaire was administered. Three categories of REB were defined: no risk, moderate risk, and high risk. A multiple regression analysis was performed. A direct relationship was found between risk of REB and BD, with significant differences between the groups (P < 0.001): no risk (83.6% of sample), 54.1% had BD; moderate risk (11.9% of sample), 84.8% had BD; and high risk (4.5% of sample), 89.9% had BD. There were significant differences in SE and BMI only between the group with no risk and each of the risk groups. Self-esteem played a role in predicting REB in all the regression models evaluated, whereas BMI did not. It is essential to identify adolescents at moderate risk of REB who have prodromic features of ED such as low SE and BD. When these features occur simultaneously, they can mediate a negative effect of BMI on REB.

The purpose of this study was to identify changes in the risk of eating disorders after a one-year follow-up of a dissonancebased eating disorders prevention program. The Body Project was implemented in a sample of male and female university students: 133, 110, and 74 at baseline, post-test, and follow-up respectively, and we tested the change in disordered eating behaviors (DEB) over time, and by levels of variables that according to the theoretical model lie on the path between the intervention and DEB, with one-way MANOVA analyses of repeated measures for the associations between internalization of the esthetic thin ideal, depressive symptoms, and DEB. The average value of DEB was 5.23 at pre-test, 3.45 at posttest, and 2.80 at follow-up. The model with DEB at each time point, as dependent variables, and internalization of the esthetic thin ideal and depressive symptoms, as independent variables, showed a significant effect of internalization of the esthetic thin ideal, F(2, 136) = 7.66, p = .0011, while there was no significant effect of depressive symptoms, F(2, 136) = 0.45, p = .6191, indicating that the intervention exerted its effect on DEB via the former variable. The intervention proved to produce effects after a one-year follow-up. These findings support the implementation of universal prevention programs using dissonance-based techniques. ,El objetivo de este trabajo fue identificar los cambios en el riesgo de desarrollar trastornos de la conducta alimentaria después de un año de seguimiento de un programa de prevención basado en la técnica de la disonancia cognitiva para trastornos de la conducta alimentaria. El Body Project fue implementado en una muestra de estudiantes universitarios, hombres y mujeres: 133, 110 y 74 en el pre-test, post-test y seguimiento, respectivamente. Se comprueba el cambio en las conductas alimentarias de riesgo (CAR) a lo largo del tiempo y según las variables que, de acuerdo con el modelo teórico, se encuentran entre la intervención y las CAR, con un análisis MANOVA de medidas repetidas para las asociaciones entre interiorización del ideal estético de delgadez, los síntomas depresivos y las CAR. El valor promedio de las CAR en el pre-test fue 5.23, 3.45 en el post-test y 2.80 en el seguimiento. El modelo de las CAR como variable dependiente e interiorización del ideal estético de delgadez y los síntomas depresivos como variables independientes mostró un efecto significativo de la internalización del ideal estético de delgadez, ,F,(2, 136), = 7.66, ,p, = .0011, mientras que no hubo un efecto significativo de los síntomas depresivos, ,F,(2, 136), = 0.45, ,p, = .6191, lo que indica que la intervención tuvo un efecto en las CAR por vía de la variable antecedente. Se mostró que la intervención produce efectos después de un año de seguimiento. Este hallazgo sustenta la implementación de programas universales de prevención que utilicen la técnica de disonancia cognoscitiva.

This study evaluated the link between relatives’ criticism of overweight or obese teenage girls’ figure and body weight and their relationship with their mothers, fathers and siblings, affection, self-esteem, the internalization of the aesthetic body thin ideal, depressive symptoms and disordered eating behaviors (DEB). The sample comprised 2174 senior high school students aged 15 to 19. Teenagers criticized by their relatives showed higher DEB, without interaction between Body Mass Index (BMI) and DEB. The structural equations model showed DEB was primarily explained by the internalization of the body aesthetic thin ideal, family’s criticism, BMI and depressive symptoms.
