Regional and socioeconomic variations in dietary patterns in a representative sample of young polish females: a cross-sectional study (GEBaHealth project).

BACKGROUND: Associations between dietary patterns (DPs) and socioeconomic correlates among adolescents from emerging economy countries are not fully understood. The study analysed variations in DPs adherence depending on country regions and family socioeconomic status (SES) among Polish females. METHODS: Data from a representative sample (n = 1107) of Polish females 13-21-year-old was used. Four DPs were previously identified by principal component analysis. Regions were ranked by Gross Domestic Product. A SES index as an overall measure of family SES was developed. Multiple logistic regression models adjusted for age and body mass index were created. RESULTS: Higher adherence to 'Fast-food and sweets' DP was found in the less affluent (North) region when compared to four other regions (Odds ratio (OR): 1.94 to 1.63). Higher adherence to 'Fruit and vegetables' DP was found in more affluent regions when compared to poorer regions: East and North-East (OR 1.71 to 1.81 and 1.69 to 2.23, respectively). Higher adherence to 'Traditional Polish' DP was found in 4 out of 5 regions (OR 2.02 to 2.53) when compared to the East. Higher family SES was associated with higher adherence to 'Fruit and vegetables' DP (OR 2.06) and lower adherence to 'Traditional Polish' DP (OR 0.27). CONCLUSIONS: The study revealed that region's affluence is strongly reflected in dietary behaviours of young females from a transitioning country. Recognising geographical distribution of dietary patterns within the country and shifting the resources to economically disadvantaged regions might be more effective than current national public health interventions.

Eating behaviors, attitudes toward health and eating, and symptoms of orthorexia nervosa among students.

The adoption of a balanced diet positively affects the state of human health; however, excessive focus on proper eating may lead to obsession about foods, described as orthorexia nervosa (ON). The aim of the study was to assess eating behaviors and concerns regarding health and eating among students with symptoms of ON. The participants were 1120 college students from seven universities in Poland enrolled in health-related majors (n = 547) and other majors (n = 573). The students completed the ORTO-15 test, Health Concern Scale (HCS) and Food Frequency Questionnaire (FFQ-6). Afterwards, eight dietary patterns were derived based on principal component analysis (PCA) ('Sweets & snacks', 'Legumes & nuts', 'Fruits & vegetables', 'Refined bread & animal fats', 'Dairy products & eggs', 'Fish', 'Meat', 'Fruit & vegetable juices'). Pearson's correlation, chi-square test, Student's t-test and one-way analysis of variance ANOVA were used for further analyses. The mean ORTO-15 score was 36.6 ±â€¯4.2. Students of health-related majors were characterized by significantly lower ORTO-15 scores than students of majors not related to health (p < 0.001). The symptoms of ON were not determined by gender and BMI. The higher symptoms of ON were associated with more frequent consumption of vegetables, fruits, nuts, legumes and meat, and less frequent consumption of sweets, snacks, refined bread and animal fats. Students with an 'ON score <35' were characterized by lower eating concerns than students with an 'ON score between 35 and 39' (p = 0.044). There was no significant association between symptoms of ON and health concerns. Nevertheless, in order to confirm this result, research should be continued with the use of other scales measuring health attitudes and symptoms of ON.

Associations between adult perception of body weight, diet, preparing meals and dietary patterns

Background: The links between dietary patterns, the perception of one's body weight and diet as well preparing meals are poorly recognised in the literature. In order to develop effective nutritional education and focused interventions, more of such information is thereby required to improve the nation's health Objective: To identify dietary patterns based on declared food consumption rates and subject responses on whether dieting, perception of body weight and diet and preparing meals are linked to such dietary patterns Material and methods: The survey was conducted in 2016 on 344 consumers chosen for age (20-65 years) and their consent for study participation. Rates of eating the foods selected were measured using a 7-point scale. Cluster analysis was used to identify three dietary patterns of behaviour: 'potentially beneficial to health', 'potentially unfavourable for health; deficient' and 'potentially unfavourable for health; excessive'. The analysis was performed using IBM SPSS Statistics version 23.0 Results: There were significantly more subjects showing 'potentially beneficial for health' behaviour, normal body weight, those dieting (whether now or in the past) and those who evaluated their diet as being very good or good compared to other groups. They were also more involved in preparing their meals at home. Differences were found between the 'unfavourable for health' dietary patterns concerning subject's involvement in meal preparation. The dietary pattern for 'deficient' behaviour found lower rates of those preparing their meals at home Conclusions: The pattern of potentially beneficial dietary habits was linked to weight control through a slimming diet and greater involvement in the preparation of food for consumption. The results show the need to develop food choice skills rather than just transferring knowledge in the nutrition education process

Enhanced neuro-therapeutic potential of Wharton's Jelly-derived mesenchymal stem cells in comparison with bone marrow mesenchymal stem cells culture.

Substantial inconsistencies in mesenchymal stem (stromal) cell (MSC) therapy reported in early translational and clinical studies may indicate need for selection of the proper cell population for any particular therapeutic purpose. In the present study we have examined stromal stem cells derived either from umbilical cord Wharton's Jelly (WJ-MSC) or bone marrow (BM-MSC) of adult, healthy donors. The cells characterized in accordance with the International Society for Cellular Therapy (ISCT) indications as well as other phenotypic and functional parameters have been compared under strictly controlled culture conditions. WJ-MSC, in comparison with BM-MSC, exhibited a higher proliferation rate, a greater expansion capability being additionally stimulated under low-oxygen atmosphere, enhanced neurotrophic factors gene expression and spontaneous tendency toward a neural lineage differentiation commitment confirmed by protein and gene marker induction. Our data suggest that WJ-MSC may represent an example of immature-type "pre-MSC," where a substantial cellular component is embryonic-like, pluripotent derivatives with the default neural-like differentiation. These cells may contribute in different extents to nearly all classical MSC populations adversely correlated with the age of cell donors. Our data suggest that neuro-epithelial markers, like nestin, stage specific embryonic antigens-4 or α-smooth muscle actin expressions, may serve as useful indicators of MSC culture neuro-regeneration-associated potency.

Associations between physical activity patterns and dietary patterns in a representative sample of Polish girls aged 13-21 years: a cross-sectional study (GEBaHealth Project).

BACKGROUND: Similar to other countries, trends of decreasing levels of physical activity (PA) and an increasing prevalence of unhealthy dietary patterns are observed among girls in Poland. Better understanding of potentially inter-related behaviours within this population can help to design tailored interventions. The purpose of this study was to determine associations between PA patterns and dietary patterns in a representative sample of Polish girls. METHODS: Girls aged 13-21 years (n = 1107) were randomly selected for the study. PA was assessed using International Physical Activity Questionnaire - Long (IPAQ-L). Dietary data were collected with food frequency questionnaires. PA patterns and dietary patterns were drawn separately by Principal Component Analysis (PCA). Logistic regression was used to find the associations between PA patterns and dietary patterns. RESULTS: Four major PA patterns ('School/work activity', 'Active recreation', 'Yard activity' and 'Walking and domestic activity') and four dietary patterns ('Traditional Polish', 'Fruit & vegetables', 'Fast food & sweets' and 'Dairy & fats') were identified. Level of PA was the highest in the upper tertile of 'School/work activity' pattern (mean 1372.2 MET-minutes/week, 95 % Confidence Intervals [CI]: 1285.9-1458.5). Girls in upper tertiles of 'Yard activity', 'Active recreation' and 'School/work activity' patterns had significantly higher chances of being in the upper tertile of the 'Fruit and vegetables' dietary pattern (odds ratio [OR] 2.17, 95 % CI: 1.50-3.14, p < 0.0001; OR 2.02, 95 % CI: 1.41-2.91; p < 0.001 and OR 1.76, 95 % CI: 1.24-2.51, p < 0.01 respectively; all adjusted for confounders) in comparison to bottom tertiles. Weak, but significant inverse associations were found between upper tertiles of 'Active recreation' and 'Yard activity' patterns and unhealthy dietary patterns. CONCLUSIONS: We found associations between PA patterns and dietary patterns in the population of Polish girls. Girls with the highest adherence to the 'School/work activity' pattern had the highest levels of PA and presented pro-healthy dietary behaviours. School should be recognised as potentially efficient and important setting to maximise girls' PA potential. The after-school time is the area that should also be targeted to increase daily PA or to at least sustain the level of PA after completing education.

Impact of health and nutrition risks perception on the interest in pro-healthy food on the example of bread.

BACKGROUND: Bread is a basic food product in the diet of a majority of people. It is a good source of energy and it is also abundant in carbohydrates. Simultaneously, because it is consumed on a large scale by Polish people, it provides large amounts of salt and some additives like preservative and raising agents. The perception of the risk influences the choice of food and impacts eating behaviors. However, it is still unknown if there is an impact of perceived risk on the choice and the consumption of bread. OBJECTIVE: The objective of the research was to assess the importance of perceived health and nutrition risk in conditioning the willingness to buy bread with decreased amounts of salt and bread without preservative and raising agents. MATERIAL AND METHODS: Empirical research was conducted in October 2014 in a group of 1.014 adult consumers, with the use of the method of interview. The questions covered the following issues: the frequency of white and wholemeal bread consumption, the willingness to consume bread with reduced salt content and one produced without the preservatives and raising agents, the self-assessment of health and socio-demographic characteristics of respondents. To evaluate the perceived health and nutrition risks modification of Health Concern Scale was used. Opinions on the tendency to purchase both kind of breads were compared taking into account socio-demographic characteristics, health risk, nutrition risk and frequency of eating white and wholemeal bread. To determine the differences ANOVA and Tukey post hoc test at the significance level of p<0.05 were used. The relations between variables were assessed using Pearson's correlation coefficient. RESULTS: There was a higher tendency to consume bread without preservatives and raising agents than with low salt content. Women, people over 55 years old, and people who often consume white bread were characterized by higher willingness to consume bread with reduced salt content. People with higher education, aged over 45 years, and those who rarely consumed wholemeal bread were more willing to eat bread without additives. The greater was the nutrition and health risk perceived by the person, the greater was the willingness to consume both types of bread. CONCLUSIONS: The importance of perceived risks in conditioning consumers' willingness to eat healthy food shows that the educational campaigns informing about risky behaviors may promote behavioral change towards a more favorable food choice.

The effect of girls attitudes towards the health benefits of food on selected dietary characteristics. The GEBahealth Project.

BACKGROUND: Dietary habits are formed at an early age and to a large extent they affect such nutritional behaviour in adulthood. Mothers in particular, influence family nutrition. In this respect, their knowledge, attitudes and behaviour about nutrition are responsible for the schooling of future generations. Many aspects of the link between food and health with nutritional behaviour in girls remain, however, unknown. OBJECTIVES: To determine the effect of girls attitudes towards the health benefits of food on selected dietary characteristics. MATERIAL AND METHODS: Study included 186 girls aged 13-21 years. Using a food frequency method the three dietary characteristics were obtained; food intake variety, fibre intake and fat intake, all of them expressed by a graded scale. Three validated questionnaires were used; FIVeQ, BSQFVF and BSQF. The girls attitudes towards the health benefits of food were rated from one of the survey's six parts, comprising of 8 statements from the Health and Taste Attitude Scale (HTAS) accordingly graded. Statistical analyses used logistic regression. RESULTS: The mean index of food intake variety was 28.7 foods/week (ranging 0-60), whilst the mean dietary intakes of fibre and fat were 16.7 points (0-36 range) and 18.2 points (0-52 range), respectively. Girls from the upper tertile with favourable attitudes on food health benefits had an odds ratio (OR) for adequate fat intake (<22 points) of 3.1 (95% CI: 1.28, 7.52; p<0.05), as compared to those from the middle-neutral attitudes tertile, with an OR = 1.00. The ORs for the relatively high food intake variety and acceptable fibre intake were 1.05 in girls from the positive-upper tertiles, which were not significant. CONCLUSIONS: The positive attitudes of girls towards the health benefits of food are conducive for making more favourable food choices and lowered dietary fat intake, however this did not significantly affect fibre intake nor food intake variety.

Safety of GMP-compliant iPSC lines generated by Sendai virus transduction is dependent upon clone identity and sex of the donor.

Human induced pluripotent stem cells (hiPSCs) are a potential source of somatic cells for cell therapies due to their ability to self-renew and differentiate into various cells of the body. To date, the clinical application of hiPSCs has been limited due to safety issues. The present study aims to standardize the safety procedure of the derivation of GMP-compliant induced pluripotent stem cell (iPSC) lines from human fibroblasts. The hiPSC lines were generated using the nonintegrative Sendai virus method to incorporate Yamanaka reprogramming factors (OCT3/4, SOX2, KLF4 and c-MYC) into cells. A constant temperature was maintained during the cell culture, including all stages of the culture after transduction with Sendai virus. Pluripotency was proved in six independently generated hiPSC lines from adult female (47 years old) and male (57 years old) donors' derived fibroblasts via alkaline phosphatase live (ALP) staining, qPCR, and immunocytochemistry. The hiPSC lines showed a gradual decrease in the presence of the virus with each subsequent passage, and this reduction was specific to the hiPSC line. The frequency and probability of chromosomal aberrations in hiPSCs were dependent on both the iPSC clone identity and sex of the donor. In summary, the generation of hiPSC for clinical applications requires safety standards application (biosafety protocol, quality control of hiPSC lines, viral and genetic integrity screening) from the first stages of the clonal selection of hiPSC from the same donor.

Consumer Perception of Innovative Fruit and Cereal Bars-Current and Future Perspectives.

The aim of the study was to ascertain consumers' interest in innovative fruit and cereal bars and their expectations of changes that could be applied by manufacturers to improve their health-promoting properties. An additional aim was to assess how these interests and expectations, as well as the information provided on the product label, determine the willingness to purchase a fruit and cereal bar with health-promoting properties. Data were collected through a quantitative CAWI survey conducted in 2020. It involved 1034 respondents. A logistic regression model was developed in which the dependent variable was the respondents' interest in an innovative fruit and cereal bar on whose packaging the manufacturer declared its health-promoting properties. It was found that producers' efforts to change the packaging to an organic one (OR = 1.24) along with enriching the product with chia seeds/flaxseed (OR = 1.22), vitamins and minerals (OR = 1.19), as well as fruit (OR = 1.14) and protein (OR = 1.12), or removing ingredients that cause allergies, would significantly increase the chance of respondents purchasing such a bar. A celebrity image and a claim that the product "helps maintain a healthy body weight" on the label would also encourage purchases. On the other hand, reducing the sugar content or enriching a fruit and cereal bar with powdered insects would significantly reduce the propensity to buy it.

Predictors of Eating Less Meat and More Plant-Based Food in the Polish Sample.

The study aimed to identify predictors of the intention to eat less meat and more plant-based foods, including attitudes towards eating meat, habitual meat eating, subjective norms, and self-identity. A cross-sectional study using CAWI (Computer-Assisted Web Interview) was conducted in a group of 1003 Polish adults in 2023. To measure the predictor variables, the following tools were used: Beliefs and Eating Habits Questionnaire (KomPAN), Meat Attachment Questionnaire (MAQ), and scales to measure subjective norms and self-identity. Logistic regression analysis was used to verify associations between independent variables, and the intentions to eat more plant-based food and less meat next year were treated as dependent variables. More respondents were willing to increase their consumption of plant-based foods rather than reduce their meat consumption. The intention to consume less meat and more plant foods was more prevalent among women, older people (only intention to reduce meat consumption), and better-educated people (only intention to increase plant food consumption). Habitual frequency of eating plant foods, negative feelings about meat, and environmentally oriented identities had a stimulating effect on the intention to eat more plant foods and less meat, while experiencing pleasure in eating meat had a limiting effect on the intention to eat more plant foods and less meat. In addition, the habitual frequency of meat consumption and subjective norms reduced the likelihood of eating less meat, while no predictive effect was observed for the intention to eat more plant foods. In conclusion, educational and promotional activities to raise awareness of the link between food consumption and the environment can have a strong impact on eating less meat and more plant-based food, even among those strongly accustomed to meat consumption.

Microcontact printing and microspotting as methods for direct protein patterning on plasma deposited polyethylene oxide: application to stem cell patterning.

Two methods for protein patterning on antifouling surfaces have been applied to analyze the density and bioactivity of the proteins after deposition. Microcontact printing has been used as a technique to transfer fibronectin through conformal contact, while piezoelectric deposition has been employed as a non-contact technique for producing arrays of fibronectin (FN). Plasma deposited polyethylene oxide-like (PEO-like) films have been used as non-fouling background to achieve the bioadhesive/biorepellent surface contrast. Both patterning methods allow the direct fabrication of protein arrays on a non-fouling substrate, and the subsequent formation of a pattern of stem cells by cell attachment on the arrayed substrates. Microcontact printing produced fully packed homogeneous fibronectin patterns, much denser than microspotted patterns. Both printing and spotting technologies generated functional protein arrays, their bioactivity being primarily modulated by the density of the deposited protein layer. Optimization of the FN parameters used for deposition has lead to the achievement of high-quality microarrays with large population of neural stem cells immobilized in the patterns in serum-free conditions, where cells exhibit a more homogeneous starting population and factors influencing fate decisions can be more easily tracked. The immunorecognition of fibronectin targeted antibodies, as well as the cell density, increase with the protein density up to a saturation point. Over 100 ng/cm² of fibronectin on the surface leads to a decrease in the number of attached cells and a raise of cell spreading.

[Bioengineering of neural stem cell niche]. / Bioinzynieria niszy neuralnych komórek macierzystych.

Maintenance of developmental and regenerative capability of the tissue highly depends upon mutual interaction of the stem cells with the components of their microenvironment (niche). The nature of this interaction is determined by the biochemical and biophysical properties of the niche constituencies. Although knowledge about the components of the stem cell microenvironment and their architecture is growing quickly, we still need to unravel the mechanisms underlying the control of the niche functioning, enabling stem cells differentiation and homeostasis of the tissue. Advancement in biotechnology provides tools to build up in vitro "biomimetic" microenvironments resembling a natural stem cell niche, where the cell is provided with diverse extracellular signals exerted by soluble and structural cues, mimicking those found in vivo. To obtain such microenvironment in vitro emerging nano/biotechnology methods were applied, using biomaterials of new generation, which enable controlling of the stem cell differentiation by time and special related release of the active factors. This article is providing an overview of the new research strategies for the bioengineering of the stem cell niche and gives the examples of the cell/biomaterial 2D and 3D complex systems used for basic and preclinical research as well as entering clinical applications for the therapy of the nervous system.

Lifestyle Variation among the Elderly: Do Nutritional Knowledge and Diet Quality Differ When the Other Lifestyle Components Are Similar?

Older people's health is strongly determined by their lifestyle, and its deterioration is a cause for concern and calls for effective efforts to slow down the process. The aim of the study was to determine the relationship between diet quality and other non-food lifestyle elements. The data were collected in 2017 through a cross-sectional survey among 271 Polish elder citizens. A K-means cluster analysis was applied to separate homogeneous groups by lifestyle components (without diet) and a logistic regression was used to analyze the relationships between identified clusters and sociodemographic characteristics, nutritional knowledge and diet quality. Three homogenous clusters were identified, i.e., individuals with moderate physical activity and recommended sleep duration (pro-healthy), with low physical activity (low PA), and with short sleep (short sleep). Gender, age, education, place of residence, BMI, and health-promoting diet index (pHDI) did not differentiate adherence to clusters. The probability of being in the pro-healthy cluster increased with nutritional knowledge and declaring the same or better health status compared to peers, while it decreased when above-average financial status was reported. The obtained results importantly extend the previous findings by showing that the individual elements of lifestyle should be also perceived in the context of others. Further research focused on lifestyle as a whole might considerably support the implementation of multifaceted lifestyle interventions.

Relationship between Food Insecurity and Nutritional Risk among Older Adults in Poland-A Preliminary Study.

Aging populations may be associated with increased nutritional risk, malnutrition, and food insecurity. This study aims to examine the relationship between food insecurity and nutritional risk, taking into account selected characteristics of the study group, and factors describing nutritional risk. It was conducted between May and July 2021, among 417 people aged 60 and older, in two regions of Poland. Questions from the SCREEN-14 questionnaire were used to assess nutritional risk. Selected questions from the HFSS questionnaire (U.S. Household Food Security Survey Module) concerning the elderly were used to assess food insecurity. A K-means cluster analysis was used to separate homogeneous clusters into food security indicators and nutritional risk factors. The Mann-Whitney U test and Kruskal-Wallis test were used to compare mean values between groups, and the Chi-square test was used to verify the differences. Two clusters were distinguished: I-"low food security and high nutritional risk" and II-"high food security and low nutritional risk". Cluster I included people aged 60-65, and over 75, living in urban areas, living alone or with family, with unfavorable economic situations and family relationships. Cluster II was composed of people aged 71-75, who were rural residents, living with a partner, with favorable economic situations and family relations. The vast majority of nutritional risk factors were found in Cluster I and among those at high nutritional risk. The largest number of people were affected by such nutritional risk factors such as difficulty in chewing or biting, loss in appetite, skipping meals, and perceiving one's weight as abnormal. Moreover, the group of people most significantly affected by high nutritional risk were in unfavorable economic situations, had poor family relationships, lived alone or with family, rated their health as worse than their peers, were overweight and obese, had metabolic disease, or impeding mobility. The results obtained can be applied to the planning of social and health policies for the elderly in Poland.

Relationship between the Prevalence of Metabolic Disease and Impaired Mobility, Diet, Physical Activity, and Socio-Demographic Characteristics in the Polish Elderly-A Cross-Sectional Study.

Maintaining good health for as long as possible presents a great challenge for the elderly. As the elderly population is growing, there is an ongoing need to identify health risk factors affecting older individuals. The study aimed to explore relationships between sociodemographic characteristics, diet, physical activity, and prevalence of metabolic diseases and impaired mobility in the Polish elderly. A cross-sectional study was carried out on 417 elderlies in May-July 2021. Cluster analysis was applied to separate four homogeneous clusters based on the prevalence of metabolic disease and impaired mobility. Logistic regression analysis was used to verify associations between variables. Being overweight or having obesity, as well as following a diet, increased the probability of being affected by metabolic disease. Being well educated, having a better financial situation, positive perception of own health, and having at least moderate physical activity decreased the probability of suffering from mobility impairments. Eating behaviors were not found to be predictors of the disease. However, they differentiated the selected clusters. The results confirmed the heterogeneity of factors that may impact healthy aging. Thus, they should be taken into account by public health authorities to develop health promotion actions adjusted to the needs of specific subgroups.

Nutrition knowledge, diet quality and orthorexic behaviors in Polish students-a pre-post repeated cross-sectional study.

Nutrition knowledge acquired in college students may not only help in promoting an adequate diet, but also lead to excessive preoccupation with healthy eating, which is referred to as orthorexic behaviors. This study aimed to assess the relationship between nutrition knowledge, diet quality and orthorexic behaviors among college students of food and nutrition majors. Data were collected from a sample of 131 college students through a pre-post repeated cross-sectional study conducted from 2018 to 2021. The participants were asked to complete the ORTO-6 questionnaire, the nutrition knowledge test "GAROTA", and the Beliefs and Eating Habits Questionnaire (KomPAN). The results indicated that students' preoccupation with healthy eating (orthorexic behaviors score) during the study period did not change, in contrast nutrition knowledge and diet quality increased. There was no correlation between the orthorexic behaviors score and the nutrition knowledge score, both at the beginning and end of the study. At the beginning of the study, the orthorexic behaviors score correlated positively with "Pro-Healthy Diet Index" and "Diet-Quality Index", and inversely with "Non-Healthy Diet Index". However, at the end of the study, no significant correlations were observed between these variables. It can be concluded that nutrition knowledge determined positively the quality of the diet of students in food and nutrition majors, while did not affect the occurrence of orthorexic behaviors.

Retrospective Reports of Parental Feeding Practices and Current Eating Styles in Polish Adults.

The role of childhood food experiences (CFEs) in determining future eating behaviors remains unclear. The aim of the study was to examine the link between CFEs and selected eating styles (ESs), i.e., intuitive (IE), restrained (ResEat) and external (ExtEat) eating, among 708 Polish adults aged 18-65 (477 women and 231 men). CFEs were measured with the Adults' Memories of Feeding in Childhood questionnaire. Polish versions of the Intuitive Eating Scale-2 and Dutch Eating Behavior Questionnaire were used to assess ESs. Mann-Whitney U test was used to compare ESs scores between those with lower and higher CFEs. In the total sample, "Restrictions" and "Pressure and Food Reward" parental feeding practices favored lower IE, while "Healthy Eating Guidance" and "Monitoring" practices predisposed higher levels of IE in adulthood. "Restrictions" were found to correlate with greater chances of ResEat, whereas "Healthy Eating Guidance" was linked with lower probability of ResEat. "Pressure and Food Reward" and "Monitoring" were associated with higher score for ExtEat. "Restrictions", "Child Control", "Monitoring" and "Healthy Eating Guidance" practices were differently linked to ESs in women and men. The findings suggest that education programs for parents should focus on the long-term consequences of feeding practices.

Childhood Food Experiences and Selected Eating Styles as Determinants of Diet Quality in Adulthood-A Cross-Sectional Study.

Available studies suggest that childhood food experiences (CFE) may be linked with eating behaviors in adulthood, as well as eating style (ES); thus, both CFE and ES can determine dietary intake. Little is known about the role of both of these factors in explaining the diet quality (DQ) of adults. The aim was to investigate to what extent selected ESs, i.e., intuitive (IE), restrained (ResEat), and external (ExtEat) eating, and CFE related to parental feeding practices (PFPs) will predict the DQ of women and men. Data from 708 Polish adults (477 women and 231 men) aged 18-65 were collected via the Internet from October 2022 to January 2023. Mann-Whitney's U Test was used to compare ES and CFE levels among women and men, while DQ determinants were tested with the multiple linear regression (MLR). In the total study sample, "Healthy Eating Guidance" (CFE), "Child Control" (CFE), "Body-Food Choice Congruence" (IE), and ResEat favored higher DQ scores, while "Unconditional Permission to Eat" (IE), "Eating for Physical Rather Than Emotional Reasons" (IE), and ExtEat predisposed to lower DQ scores. After the MLR was conducted separately in women and men, differences were noted in the role of "Healthy Eating Guidance" (CFE), "Pressure and Food Reward" (CFE), "Unconditional Permission to Eat" (IE), "Eating for Physical Rather Than Emotional Reasons" (IE), ExtEat, and ResEat in predicting DQ indices. Our findings suggest that childhood food experiences and selected eating styles may differently determine the DQ of women and men. Future studies conducted within representative samples are needed to confirm these results.

Psychometric properties of the ORTO-R in a community-based sample of women and men from Poland.

PURPOSE: Over the past two decades, orthorexia nervosa (ON) has been increasingly investigated. Recently, a new revision version of the ORTO-15, namely ORTO-R, was used. The main objective of the present study was to confirm the factor structure of Polish version of the ORTO-R for evaluating ON thoughts and behaviors. METHOD: In three studies, a total of 3081 participants was selected by random sampling through several universities and companies. In Study 1, we used original items of ORTO-15, in Study 2 we used both, the ORTO-15 items and the revised items from ORTO-R, and in Study 3 we used only the items from the ORTO-R. Confirmatory factor analysis was used for determining the factorial structure of the Polish version of the ORTO-R. We also assessed internal consistency and convergent and criterion validity of the ORTO-R. RESULTS: The model composed of the revised items (ORTO-R) was characterized of good convergent and criterion validity. Furthermore, ORTO-R appeared to be more internally consistent as compared to ORTO-15. CONCLUSION: The 6-item ORTO-R is valid and reliable method to assess orthorexic thoughts and behaviors among Polish-speaking population and could be applied in future research. Using revised version of the items is strongly preferred to using the items in their original ORTO-15 form.

Diet Quality, Dieting, Attitudes and Nutrition Knowledge: Their Relationship in Polish Young Adults-A Cross-Sectional Study.

The purpose of this study was to examine the relationships between diet quality, dieting, nutrition knowledge and attitudes in a group of Polish young adults. A cross-sectional survey was conducted in 2018 amongst 638 students of food and nutrition-related majors. Based on the frequency of consumption of 24 food groups, the "Pro-Healthy Diet Index" (pHDI) and "Non-Healthy Diet Index" (nHDI) were calculated. To assess the nutrition knowledge, the "GAROTA" test was used. The k-means clustering method was used to identify clusters-attitudes towards food and nutrition. The relationships between pHDI and nHDI indices, dieting, nutrition knowledge (NK), and attitudes towards food and nutrition were verified, using multiple linear regression analysis. The results confirmed some relationships between the variables. Higher nHDI characterized males (p < 0.0001) and people with more unfavorable attitudes towards food and nutrition (p < 0.0001), and those not using a diet (p < 0.0001). Higher nutrition knowledge (p < 0.0001) and higher BMI (p = 0.0370) were correlated with lower nHDI. Higher pHDI characterized people with more favorable attitudes (p < 0.0001) and those using a diet (p = 0.0002). Nutrition knowledge showed an adverse association with nHDI (r = −0.172, p < 0.05) and no association with pHDI. Thus, declarative nutrition knowledge does not seem to be a good indicator of healthy dietary behavior. Nutrition education programs that concentrate only on knowledge of facts, and neglect the development of favorable attitudes towards food and nutrition, may not be efficient enough to develop adequate dietary behavior of students.
