- Cluster analysis to the factors related to information about food fi bers: A multinational studyPublication . Guiné, Raquel; Correia, Paula; Leal, M.; Rumbak, I.; Baric, I.; Komes, D.; Satalic, Z.; Saric, M.; Tarcea, M.; Fazakas, Z.; jovanoska, D.; Vanevski, D.; Vittadini, E.; Pellegrini, N.; Szucs, V.; Harangozo, J.; El-Kenawy, A.; El-Shenawy, O.; Yalcin, E.; Kosemeci, C.; Klava, D.; Straumite, E.; Ferreira, Manuela; Florença, S.The adequate intake of dietary fibres is essential to human health. Hence, this work intended to evaluate the level knowledge of about food fibres and investigate what factors might be associated with it. It was undertaken a descriptive cross-sectional study on a sample composed of 6,010 participants from ten different countries. The survey was based on a questionnaire of self-response, approved and complying with all ethical issues. The data collected were subjected to factor analysis and cluster analysis techniques. Validation was made by splitting the data set into two equal parts for confirmation of the results. Factor analysis allowed concluding that ten from the 12 variables used to measure the knowledge about dietary fibre should be grouped into two dimensions or factors: one linked to health effects of dietary fibre (α =0.854) and the other to its sources (α =0.644). Cluster analysis showed that the participants could be divided into three groups: Cluster 1 – Good knowledge both about sources and health effects of dietary fibre; Cluster 2 – Good knowledge about the sources of dietary fibre but poor knowledge about its health effects; Cluster 3 – Poor knowledge both about sources and health effects of dietary fibre. The data was appropriate for analysis by means of factor and cluster analysis, so that two factors and three clusters were clearly identified. Moreover, the cluster membership was found varying mostly according to country, living environment and level of education but not according to age or gender.
- Comparison of the ingestion of fibre rich foods in different countriesPublication . Florença, Sofia G.; Leal, M.; Rumbak, I.; Baric, I.; Komes, D.; Satalic, D.; Saric, M.; Tarcea, M.; Fazakas, Z.; Szucks, V.; Harangozo, J.; Klava, D.; Straumite, E.; Guiné, RaquelIntroduction: The ingestion of fruits, vegetables and cereals, especially whole grain, is associated with a healthy lifestyle and has been recognized as having multiple health benefits, associated, among others, to the ingestion of adequate amounts of dietary fibre. Objective: The aim of this work was to evaluate some eating habits related to fibre rich foods in six different countries: Argentina, Croatia, Hungary, Latvia, Portugal and Romania. Methods: A cross-sectional descriptive study was carried out by means of questionnaire survey applied to a sample of 4905 participants, all over the age of 18 years old. The preparation and application of the questionnaire followed the necessary ethical guidelines and the treatment was made by SPSS. Results: The results showed that for the global sample was observed a low ingestion of salads and vegetables (78.2%), being this particularly problematic for Croatia (86.6%). Regarding the consumption of fruits, for the whole sample the great majority also showed a low consumption (92.3%), and for Latvian participants the percentage is very much expressive (98.3%). As for the consumption of whole cereals, most participants also showed a low consumption, either for the global sample (72.6%) or in the different countries, and particularly for Latvia (90.0%). Some eating habits were also studied and it was observed that for the whole sample 71.9% showed a low frequency of meals ate out of home, while 88.6% revealed acceptable frequency of eating fast food, i.e, only once or twice a week. Conclusions: The results indicated that in the countries at study the ingestion of foods rich in dietary fibre is very low, and therefore it is necessary to implement strategies to increase the consumption of such foods.
- Estudo Internacional do nível de conhecimento sobre insetos comestíveisPublication . Guiné, Raquel P. F.; Florença, Sofia De Guiné E; Ferreira, Manuela; Costa, Cristina Amaro Da; Correia, Paula; Cardoso, Ana Paula; Campos, Sofia; Anjos, Ofélia; Chuck-Hernandez, C.; Saric, M.; Papageorgiou, M.; Baro, J.; Korzeniowska, M.; Bizjak, M.; Bartkiene, E.; Tarcea, M.; Boustani, N.; Djekić, I.; Klava, D.; Damarli, E.Resumo: Introdução – O consumo de insetos é uma prática tradicional ao longo da história humana, mas o seu consumo é muito variável de acordo com a região do globo. Objetivos – Pretendeu-se investigar o nível de conhecimento sobre insetos comestíveis numa amostra de participantes de treze países. Métodos – Os dados foram recolhidos em 2021 por questionário online. Obtiveram-se 6899 respostas válidas. Para a análise dos dados usou-se análise fatorial, análise de clusters e testes qui-quadrado. Resultados – Foram usados 27 itens para medir o conhecimento, utilizando uma escala do tipo Likert de cinco pontos. Aplicando análise fatorial obteve-se uma solução que explica 55% da variância total observada. Esta inclui 4 fatores que retiveram 22 dos 27 itens iniciais: F1 = Sustentabilidade (8 it); F2 = Nutrição (8 it); F3 = Fatores de Produção (2 it); F4 = Preocupações com a Saúde (4 it). A análise de clusters produziu três grupos de participantes (indivíduos 'receosos', 'agricultores' e 'ecológicos'). A caracterização dos clusters revelou que a idade não influenciou a inclusão nos clusters, enquanto sexo, escolaridade, país, meio onde reside, área profissional e rendimento influenciaram a composição dos clusters. Conclusões – O nível de conhecimento sobre insetos comestíveis é altamente variável de acordo com as características individuais e localização geográfica. Por outro lado, a segmentação permitiu identificar 3 tipos de indivíduos, 'receosos', 'agricultores' e 'ecológicos'.
- Level of information about dietary fibre: a study involving 10 CountriesPublication . Guiné, Raquel; Leal, Marcela; Rumbak, I.; Baric, I.; Komes, D.; Satalic, Z.; Saric, M.; Tarcea, M.; Fazakas, Z.; Jovanoska, D.; Vanevski, D.; Yalcin, E.; Vittadini, E.; Pellegrini, N.; Szucs, V.; Harangozo, J.; El-Kenawy, A.; El-Shenawy, O.; yalcin, E.; Kosemeci, C.; Klava, D.; Straumite, E.Introduction: Dietary fibre (DF) is recognized as healthy for long, so that health claims are allowed by the European Food Safety Authority (EFSA) due to its proved benefits, extended but not only confined to many diseases of the gastrointestinal tract. Objective: This work intended to analyse the level of information about DF in 10 countries, situated in Europe, Africa and South America. Methods: A descriptive cross-sectional study was undertaken through a survey based on a questionnaire of self-response applied to a sample of 6010 participants. The data were lately treated by factor and cluster analyses, including validation methodologies. Results: Factor analysis showed that ten of the twelve items used to assess the knowledge about DF could be arranged into two factors: one related to health effects (α =0.854) and the other to the sources (α =0.644). Furthermore, cluster analysis showed that the participants could be divided into three groups: 1) Good knowledge about sources and health effects of DF; 2) Good knowledge about the sources of DF but poor knowledge about the health effects; 3) Poor knowledge about the sources and health effects of DF. Conclusions: The results clearly allowed identifying two factors and three clusters, and the variables that most influenced cluster membership were country, living environment and level of education.
- Marketing motivations influencing food choice in 16 countries: segmentation and cluster analysis.Publication . Henriques, Carla; Matos, Ana; Malva, Madalena; Bartkiene, E.; Djekic, I.; Tarcea, M.; Saric, M.; Bizjak, M.; Dolar, V.; EL-Kenawy, A.; Ferreira, V.; Klava, D.; Korzeniowska, M.; Vittadini, E.; Leal, M.; Frez-Muñoz, L.; Papageorgiou, M.; Guiné, RaquelFood behaviour is governed by different kinds of motivations, some of individual nature and others related with the external food environment. This study investigated the eating motivations in sixteen countries with respect to commercial and marketing influences on food choices. The questionnaire survey was developed between September 2017 and June 2018, via online tools, targeting a convenience sample of residents in sixteen countries (Argentina, Brazil, Croatia, Egypt, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Portugal, Romania, Serbia, Slovenia and the United States of America). The number of valid responses received was 11,919 participants. The data were treated using SPSS software, and the main statistical techniques used included exploratory factor analysis, evaluation of internal reliability through Cronbach’s alpha, cluster analysis (hierarchical and k-means) and logistic regression. The results obtained showed two groups of people: low motivated and notably motivated consumers. The results showed high asymmetries between countries, with highest percentage of highly motivated consumers in Egypt and the lowest percentage of highly motivated in Portugal. It was further observed that consumers more influenced by commercial and marketing aspects (the notably motivated) tend to be women, young, single, less educated, less likely to be professionally active, and those who live mostly in rural or suburban areas. Less exercise and overweight are also factors associated with greater propensity for commercial and marketing motivations. Furthermore, health problems such as shellfish or gluten intolerance, hypertension and high cholesterol confer less propensity to be in the segment of the notably motivated consumers. In conclusion, this work highlighted the role of geographic, sociodemographic and lifestyle factors as food choice determinants.
