[Emotional eating in university students: a cross-sectional and comparative study in the Iberian Peninsula]

Although the lack of progress in reducing obesity is a global problem, different places have different contributing factors. One of the factors currently contributing to the increasing prevalence of obesity is emotional eating. The aim of this paper was to describe and compare the level of emotional eating and to analyse which variables and to what extent they affected the other variables.

A descriptive cross-sectional study was conducted in students from 3 universities of the Iberian Peninsula (n=1,654) between October 2019 and June 2020. Data were collected through an online self-report questionnaire which included sociodemographic and anthropometric data and validated questionnaires such as: the Emotional Eaters Questionnaire, the ShortForm-36 and the Hospital Anxiety and Depression Questionnaire. Stratified random sampling was performed by faculty, degree, and class groups. For descriptive results, means, standard deviation and relative frequencies of variables were calculated. Student's t-test, chi-square and ANOVA were used to compare means. Simple and multiple linear regressions were performed for both samples.

The mean emotional eating score was 8.77±5.66 for spanish students and 10.02±6.19 for portuguese students, with a difference of 3.62 (<0.001). In Spain, the dependent variable that most affected emotional eating was quality of life (13.8% variance [<0.001]), while in Portugal it was anxiety (10.1% variance [<0.001]).

Statistically significant differences are found in the level of emotional eating between populations. In addition, there is dissimilarity in the variables influencing the principal in both countries. These findings imply that they should be considered in the design of future research or health interventions.
