- The EATMOT Project: Preliminary Results of the study about motivations for food choices in 16 countriesPublication . Guiné, Raquel; Ferreira, Manuela; Correia, Paula; Cardoso, Ana Paula; Ferrão, Ana Cristina; Mendes, Mateus; Duarte, João; Bartkiene, Elena; Tarcea, Monica; Djekic, IlijaEating is not only determined by physiology, but also by many other factors that interact in a complex way to shape individual eating habits. Hence, the aim of this project is to undertake a study about the different psychic and social motivations that determine people’s eating patterns, either in relation to their choices or eating habits. To do this, factors linked to food choices will be evaluated in the following main areas: health motivations; economic factors; emotional aspects; cultural influences; marketing and commercials or environmental concerns. The study is based on a questionnaire that was prepared purposely for the project, and therefore adequate to evaluate the aspects that determine the objectives highlighted. The study is coordinated by the principal researcher Raquel Guiné from CI&DETS Research Centre and the range is multinational, including different countries so as to gather information on a trans-frontier scale. The countries involved are: Argentina, Brazil, Croatia, Egypt, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Portugal (Coordinator), Serbia, Slovenia, Romania and United States of America. This particular study investigated the influence of sociodemographic factors on the six types of eating motivations previously referred. This is a longitudinal observational study carried out on a non-probabilistic sample with 11960 participants residing in the 16 countries afore mentioned. Analysis of the data was performed using t-test for independent samples or ANOVA with Post-Hoc Tukey HSD. Neural network models were also created, to determine the relative influence of each input on each output variable. The results showed that factors such as age, marital status, country, living environment, level of education or professional area significantly influenced all of the studied types of eating motivations. The modelling through neural networks indicated a considerable variability in the food choices, but still it was possible to identify some trends, like for example that the strongest positive factor determining health motivations was age, while for emotional motivations was living environment, and for economic & availability motivations was gender. On the other hand, country revealed a high positive influence for the social & cultural as well as for environmental & political and also for marketing & commercial motivations.

- Evalution through artificial neural networks of the sociodemographic Influences on food choicesPublication .

Objective: This study investigated the influence of sociodemographic factors on some types of eating motivations, specifically: health related factors; economic and availability aspects; emotional determinants; social, cultural and religious influences; marketing and advertising campaigns and finally environmental concerns. Methods: This is a longitudinal observational study carried out on a non-probabilistic sample with 11960 participants. For the analysis of the data were used the T-test for independent samples or ANOVA with Post-Hoc Tukey HSD, depending on the case. The modelling through artificial neural networks included 7 input variables (sociodemographic characteristics) and 6 output variables (the eating motivations’ groups). Results: Variables like age, marital status, country, living environment, level of education or professional area significantly influenced all the types of eating motivations analysed. However, regarding gender, no significant differences were observed for two of the six types of motivations analysed: economic & availability and marketing & commercial. The results of the ANN modelling showed that the strongest positive factors determining the eating motivations were age for health, country for emotional motivations, gender for economic & availability, country for social & cultural, country for environmental & political, and finally country also for the marketing & commercial motivations. Conclusions: These results highlight the importance of the sociodemographic characteristics as determinants for eating patterns around the globe, and particularly the geographic location.
