Sources of Information about Dietary Fibre: A Cross-Country Survey

Dietary fibre (DF) has been recognized as a major determinant for improvement of health. Hence the means of information through which people become aware of its benefits are crucial. This work aimed at studying the sources of information about DF, as a means to educate people about aspects related to healthy eating. Factors such as gender, level of education, living environment or country were evaluated as to their effect on the selection of sources and preferences. For this, a descriptive cross-sectional study by means of a questionnaire, applied to a non-probabilistic sample of 6010 participants from 10 countries in different continents (Europe, Africa and America), answered after informed consent by all participants. For the analysis were used several descriptive statistics tools, crosstabs and chi square test to assess the relations between some of the variables under study. The results showed that mostly the information about DF comes from the internet, but the participants recognize that television might be a most suitable way to disseminate information about DF. The results also indicated differences between genders, levels of education, living environments and countries. The internet, the preferred source of information, got highest scores for Hungary, for urban areas, for university level of education and for female gender. The radio, the least scored source of information, was preferred in Egypt, for men and with lower education (primary school). As a conclusion, people get information through the internet due to easy access. However, it is to some extent a risk given the impossibility to control de information made public on the internet. The role of health centers and hospitals as well as schools should definitely be increased, as a responsible way to ensure correct information

Level of information about dietary fibre: a study involving 10 Countries

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.info:eu-repo/semantics/publishedVersio

Evaluation of consumer habits and knowledge about dietary fibre and fibre-rich products in Turkish population

This study investigated the Turkish consumers’ knowledge about dietary fibres and purchasing behaviours about fibre rich foods and also their attitudes towards food labelling with specific emphasis on dietary fibre. The survey consisted on a longitudinal study undertaken on a sample of 293 participants. For the analysis of the data, basic descriptive statistics was used, complemented with statistical tests (U-Mann Whitney (UMW) for comparisons between two groups and Kruskal-Wallis (KW) for comparisons between three or more groups. Finally, a tree classification analysis was done to evaluate the relative importance of each of the possible influential variables on knowledge: age group, level of education, gender or living environment. The results revealed that both the level of knowledge about dietary fibre and foods and also the level of knowledge about dietary fibre and health effects were considered high for the general population. The classification analysis revealed that gender was the major discriminant for knowledge about dietary fibre and foods while the most important discriminant for knowledge about dietary fibre and health effects was age. The importance of this work resided in the highlight of the pivotal factors that influence people’s knowledge about dietary fibre sources and the health benefits of its ingestion.info:eu-repo/semantics/publishedVersio

Cluster analysis to the factors related to information about food fi bers: A multinational study

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.info:eu-repo/semantics/publishedVersio
