- 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.
- Comparative study about some eating habits in six countries: eating out and fast food consumptionPublication . Guiné, Raquel; Florença, S. G.; Leal, M.; Rumbak, I.; Komes, D.; Saric, M. M.; Tarcea, M.; Fazalas, Z.; Szucs, V.; Klava, D.; Straumite, E.; Baric, I.Poor diets have proven very detrimental for the maintenance of good health and eating an excessive amount of fast food and highly processed meals can harm the general health status of the population. Hence, this work investigates the habits related to eating outside the home and frequency of eating fast food meals in participants from six different countries. A cross-sectional descriptive study was undertaken on a sample of 4,904 adult participants. For the data treatment, basic statistics were complemented with tree classification analysis, using the CRT algorithm. This study concluded that in the sample under study the frequency of eating out of home was in general low, corresponding to four or fewer times per week for 71.9% of the participants, and the consumption of fast food meals was also acceptable, i.e., with a low frequency of up to two times per week in 88.6% of the respondents. The biggest differences were encountered when comparing participants from different age groups, countries or sexes, and not so much for living environment or education level. Tree classification analysis highlighted the relative importance of the considered factors for eating out and fast food meals, being country and age confirmed as the most influential factors. In the evaluated sample the incidence of eating out and fast food meals were low, which is a good indicator to contribute globally for the good health status of the participants involved in the study.
- 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.
- EATMOT Project: Determinants of Healthy Food Choices – Study Involving 16 CountriesPublication . Guiné, Raquel; Rumbak, I.; Sarix, M. M.The EATMOT Project is a multinational study that was carried out in 16 countries focusing on different eating motivations, taking into account their recognized importance in the definition of people’s dietary patterns. The act of eating is not only determined by physiology such as body needs of nutrients and energy, but also by many other factors that interact in a complex way to shape individual eating habits. Hence, the aim of this project was to investigate the different types of motivations that determine people’s eating patterns, either in relation to their choices or eating habits. To do this, factors linked to food choices were evaluated in the following main areas: health motivations; economic factors; emotional aspects; cultural influences; marketing and commercials or environmental concerns. The study was based on a questionnaire that was prepared purposely for the project, and dully validated. The countries involved in the study were: Argentina, Brazil, Croatia, Egypt, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Portugal (Coordinator), Serbia, Slovenia, Romania and United States of America. The collected results included 11,960 validated respondents, whose data was used to characterize the eating motivations in different parts of the world, including those linked with healthy eating. These results are valuable allies to shape interventions aimed at motivating people towards healthier diets. In the modern era, individuals have been increasingly recognizing the concept of dietary health, and therefore the group and individualized guidance on nutritional and healthy eating habits are becoming more relevant.
- Environmental Issues as Drivers for Food Choice: Study from a Multinational FrameworkPublication . Guiné, Raquel P. F.; Batkiene, E.; Florença, S. G.; Djekić, I.; Bizjak, M. C.; Tarcea, M.; Leal, M.; Ferreira, V.; Rumbak, I.; Orfanos, P.; Szucs, V.; Klava, D.; Korzeniowska, M.; Isoldi, K.; Correia, Paula; Ferreira, Manuela; Cardoso, Ana PaulaThis work intended to explore some motivations that influence people’s eating habits to- wards sustainability. This was an observational, cross-sectional study, carried out by questionnaire survey on a non-probabilistic sample of 10,067 participants from 13 countries (Argentina, Brazil, Croatia, Greece, Hungary, Latvia, Lithuania, Poland, Portugal, Serbia, Slovenia, Romania and United States). Results indicated that people prefer fresh local foods from the season, being im- portant because it allows transportation and storage to be reduced, which in many cases implies refrigeration systems and consequent energy expenditure. Although people avoid food waste at home, the awareness for the waste at restaurants still needs to be improved. Consumers seem to prefer foods that have been produced and packed in sustainable ways but still give importance to the package—understandable for food products. The results also indicated significant differences in the food choice motivations between groups for all sociodemographic variables tested (age, sex, marital status, education, professional area, living environment and country), but the association was high only for variable country. Additionally, a tree classification analysis allowed to identify the relative importance of the influential variables on the sustainable food choices, with country being the most important, followed by age and sex. Additionally, discriminant function analysis allowed establishing a model for the relation between country and six variables accounting for preservation of biodiversity, respect for life, save natural resources, save energy, reduce industrial pollution and minimal packaging. Although with some limitations, this study brings valuable in- sight into some aspects linked with sustainable food choices on a number of countries and how people shape their food choices according to some sustainability issues.
- Factor and cluster analysis to knowledge about dietary fibrePublication . Guiné, Raquel; Correia, Paula; Klava, D.; Straumite, E.; Szűcs, V.; Harangozó, J.; Tarcea, M.; Fazakas, Z.; Rumbak, I.; Barić, I. C.; Komes, D.; Satalić, Z.; Sarić, M. M.; Yalçın, E.; Kösemeci, C.; Leal, M.; Jovanoska, D.; Vanevski, D.; Vittadini, E.; Pellegrini, N.; EL-Kenawy, A.; EL-Shenawy, O.The present study was aimed at investigating what are the people’s levels of information about dietary fibre (DF) and how they relate to some fators that result from the people’s perceptions associated with the knowledge about DF. The study consisted of a descriptive cross-sectional survey undertaken on a sample of over 6 thousand participants, original from 10 countries. Statistical techniques like factor analysis and cluster analysis were applied to the data. Factor analysis showed that 10 out of the 12 variables used to measure the knowledge about DF could be grouped into 2 factors: one associated with health effects of DF and the other with its natural sources. The internal consistency of both factors was evaluated by the Cronbach’s alfa (0.854 and 0.644, respectively). Cluster analysis revealed that the participants could be divided into 3 groups: Cluster 1 – Good knowledge both about sources and health effects of DF; Cluster 2 – Good knowledge about the sources of DF but poor knowledge about its health effects; Cluster 3 – Poor knowledge both about sources and health effects of DF. The results were subject to analysis of stability by spliting the data set in 2 halfs. The cluster membership was found associated with living environment and level of education, but not with age, gender or country.
- Food choices as influenced by environmental concerns: study involving participants from 16 countriesPublication . Guiné, Raquel; Ferreira, Manuela; Correia, Paula; Leal, M.; Ferreira, V.; Rumbak, I.; El-Kenawy, A.; Papageorgiou, M.; Szucs, V.; Vittadini, E.; Klava, D.; Bartkiene, E.; Munoz, L.; Korzeniowska, M.; Tarcea, M.; Djekić, I.; Bizjak, M.; Isoldi, K.The activities related to food production, processing, handling, transportation, storage and disposal of food products have an important impact on sustainability. Hence, people’s food choices also contribute for the definition of the extension of this impact and therefore this work aimed at studying some motivations that influence people’s eating habits. This was an observational, cross-sectional study, undertaken on a non-probabilistic sample of 11960 participants form 16 countries (Argentina, Brazil, Croatia, Egypt, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Portugal, Serbia, Slovenia, Romania, United States of America). The survey was undertaken by means of a questionnaire of self-response, applied only to adult citizens. The results obtained indicated that a great number of participants admit to shape their food choices according to some environmental concerns, like, for example, they prefer foods from the season or those that comply with sustainable processing and packaging. Regarding the food surplus, this seems a priority to avoid at home, but not so much when it comes to restaurants. Factor analysis indicated two types of concerns: Purely Environmental Concerns (PEC) and Sustainability allied to Quality Concerns (SQC), and cluster analysis showed that 54% of the participants tend to make their food choices considering both types of concerns, which is very expressive and positive towards sustainability of the food chain.
- Is Better Knowledge about Health Benefits of Dietary Fiber Related to Food Labels Reading Habits? A Croatian OverviewPublication . Ljubičić, M.; Sarić, M. M.; Rumbak, I.; Barić, I. C.; Sarić, A.; Komes, D.; Šatalić, Z.; Dželalija, B.; Guiné, Raquel P. F.The aim of this cross-sectional study was to determine the associations between health dietary patterns, knowledge, and consumption of dietary fiber (DF) with frequency of food label reading on food products with special reference to DF. The study was conducted in 2536 Croatian adults using an original questionnaire. Multiple linear regression models were used to assess associations between food label reading habits and predictor variables. Our study confirms the association between habits regarding the reading of labels on food products, especially in relation to information about DF with the sociodemographic factors of respondents, dietary food patterns and DF consumption, as well as knowledge and sources of information about DF. Women, individuals with a university-level education, and those living in an urban environment had more frequent labels used. Food habits as well as eating outside of the home were positive predictors while eating fast food was a negative predictor of food label reading. Knowledge about DF, especially about its health benefits, was also associated with food label reading. The interpretation of associations could help with the design of effective public health programs. Targeted education campaigns to educate and sensitize the population about food labeling and monitoring may improve general knowledge about healthy food and its benefits, which include indirect effects on the prevention of non-communicable chronic diseases.
- Knowledge about dietary fibres (KADF): development and validation of an evaluation instrument through structural equation modelling (SEM)Publication . Guiné, Raquel; Duarte, J.; Ferreira, M.; Correia, P.; Leal, M.; Rumbak, I.; Barić, I.C.; Komes, D.; Satalić, Z.; Sarić, M.M.; Tarcea, M.; Fazakas, Z.; Jovanoska, D.; Vanevski, D.; Vittadini, E.; Pellegrini, N.; Szűcs, V.; Harangozó, J.; EL-Kenawy, A.; EL-Shenawy, O.; Yalçın, E.; Kösemeci, C.; Klava, D.; Straumite, E.Objectives: Because there is scientific evidence that an appropriate intake of dietary fibre should be part of a healthy diet, given its importance in promoting health, the present study aimed to develop and validate an instrument to evaluate the knowledge of the general population about dietary fibres. Study design: The present study was a cross sectional study. Methods: The methodological study of psychometric validation was conducted with 6010 participants, residing in ten countries from 3 continents. The instrument is a questionnaire of self-response, aimed at collecting information on knowledge about food fibres. For exploratory factor analysis (EFA) was chosen the analysis of the main components using varimax orthogonal rotation and eigenvalues greater than 1. In confirmatory factor analysis by structural equation modelling (SEM) was considered the covariance matrix and adopted the Maximum Likelihood Estimation algorithm for parameter estimation. Results: Exploratory factor analysis retained two factors. The first was called Dietary Fibre and Promotion of Health (DFPH) and included 7 questions that explained 33.94 % of total variance ( = 0.852). The second was named Sources of Dietary Fibre (SDF) and included 4 questions that explained 22.46% of total variance ( = 0.786). The model was tested by SEM giving a final solution with four questions in each factor. This model showed a very good fit in practically all the indexes considered, except for the ratio 2/df. The values of average variance extracted (0.458 and 0.483) demonstrate the existence of convergent validity; the results also prove the existence of discriminant validity of the factors (r2 = 0.028) and finally good internal consistency was confirmed by the values of composite reliability (0.854 and 0.787). Conclusions: This study allowed validating the KADF scale, increasing the degree of confidence in the information obtained through this instrument in this and in future studies.
- Knowledge about sources of dietary fibres and health effects using a validated scale: a cross-country studyPublication . Guiné, Raquel; Duarte, J.; Ferreira, M.; Correia, P.; Leal, M.; Rumbak, I.; Barić, I.C.; Komes, D.; Satalić, Z.; Sarić, M.M.; Tarcea, M.; Fazakas, Z.; Jovanoska, D.; Vanevski, D.; Vittadini, E.; Pellegrini, N.; Szűcs, V.; Harangozó, J.; EL-Kenawy, A.; EL-Shenawy, O.; Yalçın, E.; Kösemeci, C.; Klava, D.; Straumite, E.Objectives Dietary fibre (DF) is one of the components of diet that strongly contributes to health improvements, particularly on the gastrointestinal system. Hence, this work intended to evaluate the relations between some sociodemographic variables such as age, gender, level of education, living environment or country on the levels of knowledge about dietary fibre (KADF), its sources and its effects on human health, using a validated scale. Study design The present study was a cross-sectional study. Methods A methodological study was conducted with 6010 participants, residing in 10 countries from different continents (Europe, America, Africa). The instrument was a questionnaire of self-response, aimed at collecting information on knowledge about food fibres. The instrument was used to validate a scale (KADF) which model was used in the present work to identify the best predictors of knowledge. The statistical tools used were as follows: basic descriptive statistics, decision trees, inferential analysis (t-test for independent samples with Levene test and one-way ANOVA with multiple comparisons post hoc tests). Results The results showed that the best predictor for the three types of knowledge evaluated (about DF, about its sources and about its effects on human health) was always the country, meaning that the social, cultural and/or political conditions greatly determine the level of knowledge. On the other hand, the tests also showed that statistically significant differences were encountered regarding the three types of knowledge for all sociodemographic variables evaluated: age, gender, level of education, living environment and country. Conclusions The results showed that to improve the level of knowledge the actions planned should not be delineated in general as to reach all sectors of the populations, and that in addressing different people, different methodologies must be designed so as to provide an effective health education.
