- Determinants of economic motivations for food choice: insights for the understanding of consumer behaviourPublication . Martinho, Vítor; Bartkiene, Elena; Djekic, Ilija; Tarcea, Monica; Barić, Irena Colić; Černelič-Bizjak, Maša; Szűcs, Viktória; Sarcona, Alessandra; El-Kenawy, Ayman; Ferreira, Vanessa; Klava, Dace; Korzeniowska, Małgorzata; Vittadini, Elena; Leal, Marcela; Bolhuis, Dieuwerke; Papageorgiou, Maria; Guiné, Raquel P. F.Food consumption involves several dimensions, being some of them directly associated with the consumers’ characteristics. The interrelationships between these domains impact consumer behaviour for food choice and the consequent decisions for food consumption. In these frameworks, economic motivations are determinant. On the other hand, the scientific literature highlights that the economic-based stimuli to choose food is still underexplored. In this perspective, the objective of this study was to assess the main sociodemographic and anthropometric determinants of the economic motivations for food choice. For that, a questionnaire survey was carried out involving 11,919 respondents from 16 countries. A validated questionnaire was used, translated into the native languages in all participating countries, using a back-translation process. First, the information obtained was assessed through factor analysis to reduce the number of variables associated with the economic motivations and to identify indexes. After, and considering the indexes obtained as dependent variables, a classification and regression tree analysis was performed. As main insights, it is highlighted that the main determinants of the economic motivations are country of residence, age, gender, civil state, professional activity, educational level, living environment, responsibility for buying food, weight, height, body mass index, healthy diets and physical exercise practices. Additionally, the results also reveal that economic motivations may be associated with two indexes, one related to convenience attitudes and the other to quality concerns. Finally, the younger persons and the women are the social groups more concerned with healthy diets and food quality. In conclusion, this work confirmed that food choice is to a high extent influenced by several sociodemographic and behavioural factors.
- The impact of food choices on human and animal rights protection and environmental sustainabilityPublication . Guiné, Raquel; Correia, Paula; Ferreira, Manuela; Tarcea, Monica; Bartkiene, Elena; Vittadini, ElenaIntroduction: People’s food choices are of the utmost importance to regulate markets and the food chain towards the global goal of sustainability. Objectives: The objective of this work was to evaluate to what extent some aspects linked to sustainability in the food chain influence people’s food choices, specifically in the domains of packaging, food surplus, transportation and human or animal welfare. Methods: This is a cross-sectional study involving 3183 people from Portugal, Italy, Lithuania and Romania, who participated in this questionnaire survey between January and June 2018. Results: People tend to condition their food choices in view of contributing for a more sustainable food chain with respect for environment, humans and animals. The areas in which this behaviour is stronger include avoiding food waste at home (80% of participants), preference for local foods (60%), sustainable food growing, preparation or packaging (66%). The respect for animal rights is very important for 62% of the participants, but the respect for Human rights is a concern for just 32%. The results of statistical tests indicated that age, education, country, professional area and type of diet all significantly influenced people’s choices regarding the sustainability of the food chain. Conclusions: Although the results are indicative that people start to condition their eating behaviours also according to sustainability issues, it is a fact that there is still work to be done, since the adoption of these sustainable choices is still in a limited extent.
