- Analysis of factors that influence eating habits in different countriesPublication . Kalnina, I.; Straumite, E.; Klava, D.; Kruma, Z.; Bartkiene, E.; Isoldi, K.K.; Correia, Paula; Ferreira, Manuela; Guiné, Raquel P. F.Individual eating habits are influenced by a number of factors, including both internal variables such as physiology and emotion, as well as environmental factors such as food availability and cultural norms. Given the public health impact of dietary habits (choice, quality, amount, frequency) on health outcomes, it is important to understand what factors influence eating habits on a societal level. The aim of this research was to determine factors that influence eating habits and compare these factors between four different countries – Latvia, Lithuania, Portugal and the USA. An eating motivation questionnaire was used to measure eating habits in 3,348 respondents from different regions and countries. There were ten parts - demographical information, anthropometric data and behavioral and health related elements, sources of information about healthy eating, factors related to food choices according to motivations (health, emotional, economic, availability, social, cultural, environmental, political, marketing and commercials). Data were analyzed using descriptive statistics, and self-reported motivation was compared across countries. Health was the primary motivator of food selection in this sample (71% of respondents), whereas 34% reported that emotional factors impact their dietary habits and 35% reported that economic factors determine their food selection. A large number of respondents (44%) disagreed or strongly disagree or disagreed with the idea that marketing impacts their dietary habits. Portugal had the highest number of participants (86%), reporting that they agreed or strongly agreed with having health-related motivations for food selection, with Latvia (65%) and Lithuania (76%) showing more moderate levels of endorsement of healthy eating motivations, and the USA having the fewest respondents (52%) endorsing health-related motivations. Respondents from Portugal were more likely than respondents from the other countries to deny having emotional, economic and marketing motivations in food selection. From results can conclude that consumers are motivated by healthiness factors when making food choices (71% of respondents), but marketing, economic and emotional factors positively impact only 30% of consumers, other respondents completely disagreed or was indifferent to these types of motivations. Baltic countries (Latvia and Lithuania) were similar to each other, but Portugal and USA were completely different. Portugal strongly agreed with healthy motivations and disagreed with all other motivations, whereas USA and also Baltic countries had more equal division of opinions regarding impact of different motivations.
- 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.
- Consumer perception about edible insects’ relation with environment and sustainabilityPublication . Guiné, Raquel P. F.; Klava, D.; Straumite, E.; Kruma, Z.; Florença, S. G.; Anjos, O.; Djekic, I.; Chuck-Hernandez, C.; Matek Saric, M.; Bartkiene, E.; Boustani, N. M.; Papageorgiou, M.; Baro, J. M. F.; Korzeniowska, M.; Cernelic-Bizjak, M.; Tarcea, M.; Damarli, E.; Ferreira, V.The interest in adopting more sustainable diets can be a driver for consumers to engage the consumption of edible insects, even in countries where they are not culturally accepted as food. This work aimed to study the perceptions and knowledge of consumers in different countries towards edible insects and their relation with environment and sustainability. The present investigation was based on a questionnaire survey (11 questions) and this descriptive cross-sectional study was carried out on a non-probabilistic sample of 7221 participants from 14 countries. The participants in the survey revealed high knowledge (over 50%) about the sustainability issues related with edible insects as food. The sociodemographic variables education, sex and age are influential, by decreasing order of importance. Regarding living environment, rural areas have the lowest percentage of informed participants. Comparing countries, statistically significant differences were observed for all questions, making this the most important predictor for information about sustainability of edible insects. This is expected, having in mind that cultural influences are highly variable among the set of countries included in the study, with a high number of European countries, but also with Latin American countries like Mexico or Brazil, or Middle East countries like Turkey or Lebanon.
- 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.
- Information, Perceptions and Motivations for Healthy Eating on a Group of European CountriesPublication . Guiné, Raquel; Correia, Paula; Ferreira, Manuela; Duarte, João; Cardoso, Ana Paula; Bartkiene, E.; Lele, v.; Starkute, v.; Juodeikiene, G.; Adomaitiene, V.; Steibliene, V.; Zadeike, D.; Szűcs, V.; Hámori, J.; Bizjak, M. C.; Stubelj, M.; Klava, D.; Straumite, E.; Kruma, Z.; Tarcea, M.; Fazakas, Z.; Buicu, F.; Ruta, F.; Rus, V.This is an original research work that is a part of the EATMOT project, which aims to study the eating motivations of different nature in a set of countries all over the world. In this work will be presented some results of the project, regarding three major areas: perceptions about healthy eating, sources of information about healthy diet and healthy motivations for food choice. This is a longitudinal observational study carried out on a non- probabilistic sample with 4870 participants residing in 6 European countries: Hungary, Latvia, Lithuania, Portugal, Romania and Slovenia. Analysis of the data was performed using descriptive statistics and t-test for independent samples or ANOVA with Post-Hoc Tukey HSD, depending on the case. The results obtained allowed concluding that most of the participants have some knowledge about what a healthy diet entails, but still one third did not manifest an opinion for the questions related to healthy eating. Regarding the sources of information about healthy eating, internet was the source more frequently used by a significant part of the participants, while hospitals and health centres were quite irrelevant. This raises some concerns because the internet mighht not always be a reliable source of information. Finally, it was found that the health factors were more influential for the food choices in older people, females, widowed, retired and people working or studying in the area of nutrition.
- 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.
- Latvian citizens knowledge about dietary fiberPublication . Klava, D.; Straumite, E.; Kruma, Z.; Guiné, RaquelThe positive benefits of DF associated with the regulation of the intestinal transit, and the prevention or treatment of diabetes, cardiovascular diseases and regulate colon cancer and obesity. The aim of this research was to collect information on knowledge about dietary fibre on citizens’ of Latvia. The questionnaire consists 22 questions, which aim was to evaluate knowledge on three distinct areas: six for knowledge about food fibres; six for the relation between fibres and variety of foods and 12 for the relations between fibres and diseases. The methodological study was conducted with 231 participants, from which 64.9% were female and 35.1% male, aged between 17 and 80 years. The respondents were selected by convenience, although of age, literacy, gender, geographical area of residence, including people from different cities and smaller villages. 67% of respondents consider that the consumption of sufficient amounts of fibres can prevent or treat different diseases. 85% of respondents have noted that legumes (peas, beans) are source of fibres, but more possible take up the fibre with a combination of vegetables and animal products. This research was prepared in the ambit of the multinational project from CI&DETS Research Centre (IPV e Viseu, Portugal) with reference PROJ/CI&DETS/2014/0001.
