- 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.
- 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.
