Gender differences in perceived food healthiness and food avoidance in a Swedish population-based survey: a cross sectional study

Food neophobia and its association with sociodemographic factors and food preferences among Bangladeshi university students: Evidence from a cross-sectional study

Food neophobia, described as a reluctance to eat and or avoid new food, is a personality trait that affects food choice. Despite its potential influence on an individual's food intake, food neophobia has been poorly investigated in Bangladesh. This cross-sectional study was designed to evaluate food neophobia and its association with sociodemographic factors and food preferences in a sample of Bangladeshi university students. Five hundred students from five public universities completed the structured surveys. Food neophobia was assessed by a 10-item validated food neophobia scale with some minor modifications based on study settings. A multiple linear regression model was used to observe the factors associated with food neophobia. The mean food neophobia score among study participants was 37.45 (SD: 13.39, Range: 13-67). According to the adjusted statistical model, being female (regression coefficient, β = 2.73), having higher monthly family income (β = -6.64), being underweight (β = 4.68), being overweight (β = -4.63), having any food allergy (β = 9.09), and a history of sickness after eating a new food item (β = 5.16) were significantly associated with food neophobia amongst the participants. The participants' liking of various food items such as vegetables were significantly correlated with food neophobia scores. Nutrition education policies and programs are of importance to address the students' food neophobia during their tertiary education so that they maintain lifelong healthy dietary habits and consume a variety of foods to improve their physical health and well-being.

Combination of Risks of BMI and Health-Related Lifestyles on Kidney Function in the Prediabetic Japanese Population: A Prospective Cohort Study

Diabetic overweight patients are more likely to show the progression of kidney damage than the general population. The majority of people in the early stages of kidney damage do not recognize the importance of risk modification, mainly due to the asymptomatic nature of the disease. This study aimed to examine specific risk combinations of lifestyle and BMI regarding the deterioration of kidney function and to explore whether there are gender-based differences among the prediabetic population. Prediabetic participants with normal kidney function were identified via annual health examination from April 2016 to March 2019. The information on health status and lifestyle was collected at enrollment. The study subjects were followed until March 2021 to observe the progression of kidney damage. There were 2241 participants enrolled in this study. Smoking (HR = 3.5, p < 0.001), eating snacks (HR = 3.2, p < 0.001), not engaging in regular exercise (HR = 2.9, p < 0.001), and not having adequate sleep (HR = 3.0, p < 0.001) showed accelerated risks for kidney damage progression among the prediabetic population in males. These lifestyle effects were not observed in females. In conclusion, risk-based modification of lifestyle behavior is important to prevent kidney function damage among the overweight prediabetic population in males.

A 7 day inpatient diabetes education program improves quality of life and glycemic control 12 months after discharge

AIMS

For long-term management of diabetes, patients with type 2 diabetes mellitus require a high level of treatment adherence, which is associated with treatment satisfaction and their quality of life (QOL). To achieve it, patient education about diabetes self-management is essential. We routinely conduct a 7 day inpatient diabetes education program and administer the diabetes treatment-related (DTR)-QOL questionnaire to all participants, both before admission and at discharge. Here, we investigated whether our program improves QOL and post-discharge glycemic control.

MATERIALS AND METHODS

This retrospective study utilized data from patients with type 2 diabetes mellitus who participated in our program between July 2017 and March 2020 and who had been treated in our outpatient department for more than 1 year. We evaluated the relationship between at admission and at discharge diabetes treatment-related quality of life scores and glycemic control after discharge.

RESULTS

Data from 140 patients were analyzed in this study, which showed a significant improvement in the total, 'Anxiety and dissatisfaction with treatment', and 'Satisfaction-with-treatment' scores. A significant improvement was evident in HbA1c at 12 months after discharge. Multiple regression analysis showed that HbA1c after 12 months was independently associated with gender, duration of diabetes, and HbA1c at admission.

CONCLUSIONS

Our program effectively improves quality of life and post-discharge glycemic control in patients with type 2 diabetes mellitus. It is particularly effective in patients of the male gender, with a shorter duration of diabetes mellitus and higher HbA1c at admission.

The attitude of Polish consumers toward food irradiation as one of the methods of food preservation

Background

Food irradiation is one of the methods of food preservation. Unfortunately, despite many opinions from national and international organizations that confirm the safety of the irradiation technique, the irradiated food market is slowly developing, which is particularly noticeable in European countries, including Poland.

Objectives

The main objective of this study was to determine the attitude of Polish consumers toward irradiated food and to find out whether familiarizing the respondents with educational materials on the irradiation technique would change their attitudes.

Material and methods

In response to the objective of the study, an online survey (with the presentation of educational materials) was conducted with 609 respondents living in the Silesian Voivodeship, Poland. A specially prepared author's questionnaire was used, containing questions relating to: sociodemographic data, food preservation, food irradiation. An integral part of the survey was a multimedia presentation containing information about the food irradiation process.

Results

A low level of knowledge about food irradiation was found--90.31% (n = 550) of the respondents had never heard of this method of preservation before. The percentage of respondents with a positive attitude toward radiation-preserved products increased significantly after providing informative material, from 6.20 (n = 38) to 67.16% (n = 409). The final attitude of the respondents toward irradiated food varied and depended on age, education and place of residence-positive attitudes toward irradiation predominated among those who were young (<30 years old), had a higher education and lived in cities >100,000 inhabitants. Educational materials also had a significant impact on consumers' interest in purchasing irradiated food-the percentage of people declaring a willingness to purchase this type of product increased from 19.20 (n = 117) to 59.30% (n = 361). Almost 60% of the respondents were willing to purchase irradiated foods. Women, on average, were more likely to be interested in purchasing irradiated food compared to men.

Conclusions

The survey indicates that irradiated food could be commercially introduced in Poland, but on the condition that an effective educational program is planned.

Adolescent exposure to food and beverage marketing on social media by gender: a pilot study

OBJECTIVE

The objective of this research was to determine if, based on gender, adolescents were exposed to different marketing techniques that promoted food and beverages over social media.

DESIGN

A secondary analysis of adolescent boy (n 26) and girl (n 36) exposures (n 139) to food and beverage marketing was conducted. Mann-Whitney U and Fisher's exact tests were conducted to compare the number, healthfulness and the marketing techniques of exposures viewed by boys and girls.

SETTING

Ottawa, Ontario, Canada.

PARTICIPANTS

Sixty-two adolescents aged 12-16 years.

RESULTS

Boys and girls were exposed to similar volumes of food marketing instances (median = 2 for both boys and girls, Mann-Whitney U = 237, P = 0·51) per 10-min period of social media use. More girls viewed products that were excessive in total fat compared to boys (67 % v. 35 %, P = 0·02). Boys were more likely to view instances of food marketing featuring a male as the dominant user (50 % v. 22 %, P = 0·03), appeals to achievement (42 % v. 17 %, P = 0·04), an influencer (42 % v. 14 %, P = 0·02) and appeals to athleticism (35 % v. 11 %, P = 0·03), whereas girls were more likely to view instances of food marketing featuring quizzes, surveys or polls (25 % v. 0 %, P = 0·01).

CONCLUSIONS

Food and beverage companies utilise marketing techniques that differ based on gender. More research examining the relationship between digital food and beverage marketing and gender is required to inform the development of gender-sensitive policies aimed at protecting adolescents from unhealthy food marketing.

Sex-specific interventions to prevent and manage frailty

There is growing interest in interventions that delay, slow, and even reverse frailty. In this narrative review, we explore the evidence on exercise, nutrition, medication optimisation and social support interventions for frailty and consider how these relate to underlying frailty pathophysiology. We also consider pathophysiological mechanisms underpinning sex differences in frailty before evaluating the limited evidence for sex-specific frailty interventions that is currently available. Through this review of the literature, we generate a list of potential sex-specific interventions for frailty. While individual-level recommendations are certainly important, future work should turn the focus towards population-level interventions that take into account sex differences in frailty, including changes to healthcare and socioeconomic systems, as well as changes to the built environment to promote healthy behaviours.

Baseline characteristics of participants in the Pre-Diabetes Interventions and Continued Tracking to Ease-out Diabetes (Pre-DICTED) Program

OBJECTIVE

The Pre-Diabetes Interventions and Continued Tracking to Ease-out Diabetes (Pre-DICTED) Program is a diabetes prevention trial comparing the diabetes conversion rate at 3 years between the intervention group, which receives the incentivized lifestyle intervention program with stepwise addition of metformin, and the control group, which receives the standard of care. We describe the baseline characteristics and compare Pre-DICTED participants with other diabetes prevention trials cohort.

RESEARCH DESIGN AND METHODS

Participants were aged between 21 and 64 years, overweight (body mass index (BMI) ≥23.0 kg/m2), and had pre-diabetes (impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT)).

RESULTS

A total of 751 participants (53.1% women) were randomized. At baseline, mean (SD) age was 52.5 (8.5) years and mean BMI (SD) was 29.0 (4.6) kg/m2. Twenty-three per cent had both IFG and IGT, 63.9% had isolated IGT, and 13.3% had isolated IFG. Ethnic Asian Indian participants were more likely to report a family history of diabetes and had a higher waist circumference, compared with Chinese and Malay participants. Women were less likely than men to meet the physical activity recommendations (≥150 min of moderate-intensity physical activity per week), and dietary intake varied with both sex and ethnicity. Compared with other Asian diabetes prevention studies, the Pre-DICTED cohort had a higher mean age and BMI.

CONCLUSION

The Pre-DICTED cohort represents subjects at high risk of diabetes conversion. The study will evaluate the effectiveness of a community-based incentivized lifestyle intervention program in an urban Asian context.

Diet Quality of Adolescents and Adults Who Completed the Australian Healthy Eating Quiz: An Analysis of Data over Six Years (2016-2022)

Diet quality is influenced by demographics and can change over time. This study aimed to (1) compare diet quality among adolescents/adults who completed the online Healthy Eating Quiz (HEQ) by demographic characteristics, and (2) to evaluate change in score over time for repeat completers. HEQ data collected between July 2016 and May 2022 were analysed, including demographics (age, gender, vegetarian status, socio-economic status, number of people main meals are shared with, country), and diet quality calculated using the Australian Recommended Food Score (ARFS) (range 0−73) for respondents aged ≥ 16 years. Differences in ARFS by demographic characteristics and change in score over time, adjusted for age, gender and vegetarian status, were tested by linear regression. The participants (n = 176,075) were predominantly female (70.4%), Australian (62.8%), and aged 18−24 years (27.7%), with 4.0% (n = 7087) repeat completers. Mean ± SD ARFS was 33.9 ± 9.4/73. Results indicate that ARFS was significantly lower among males and significantly higher with increasing age group, higher socio-economic status, in vegetarians, those who shared main meals with others, and those living in Australia (p-values < 0.001). Mean change in ARFS over time (2.3 ± 6.9) was significantly higher for those with lower baseline scores (p < 0.001). Publicly available, brief dietary assessment tools have the potential to improve diet quality at the population level.

Prevalence of Female and Male Vegan and Non-Vegan Endurance Runners and the Potential Associations of Diet Type and BMI with Performance-Results from the NURMI Study (Step 1)

This study aims to investigate vegetarian and mixed diet type prevalences among distance runners at running events around the world and associations with running-related patterns and performance. Following a cross-sectional approach, linear regression analyses were carried out to identify potential associations among body mass index (BMI), diet type, and average best performance times of half-marathon and marathon events for males and females. From a sample of 3835 runners who completed an online questionnaire, 2864 all-distance runners (age: 37 years; 57% females) were included in inferential analyses and categorized into dietary subgroups according to self-reports: 994 vegans (34.7%), 598 vegetarians (20.9%), and 1272 omnivores (44.4%). Significant associations were identified between kind of diet and best average time to finish (i) half-marathons in females where vegans (p = 0.001) took longer than omnivores, (ii) half-marathons in males where vegans (p < 0.001) and vegetarians (p = 0.002) took longer than omnivores, and (iii) marathons in males where vegans (p < 0.001) and vegetarians (p = 0.043) averaged slower than omnivores. Increased units of BMI (+1.0) in males influenced best runtimes: 2.75 (3.22−2.27) min slower for HM and 5.5 (5.69−4.31) min slower for M. The present study did not take detailed confounders into account such as runner motives or training behaviors; however, the results may provide valuable insight for running event organizers, nutrition experts, coaches, and trainers advising runners who adhere to a general diet type regarding the basic question of who participates in running events around the world.

Sociodemographic and dietary influences on perceptions of eating habits in Jamaica

Objective.

To evaluate how sociodemographic factors and food intake affect survey respondents’ perceptions of the quality of their diet.

Methods.

This cross-sectional analysis is based on a nonprobability sample of 374 participants in Jamaica aged ≥18 years. The three-stage process used a simple random sample to select three parishes; the main commercial areas of each parish were chosen for sampling. To ensure the inclusion of a cross-section that was as representative as possible, the sample included both public and private sector businesses, such as those in retail, hospitality and tourism as well as nongovernmental organizations. Employees and patrons completed a questionnaire regarding their food consumption and their perception of their own diet. Multiple correspondence analysis was used to evaluate the nonlinear relationships among the variables. The results of the analysis guided the specification of a multivariate logistic regression model that was used to estimate the relationship between sociodemographic factors, food intake and perceived eating patterns.

Results.

The average predicted probability of perceiving a diet as unhealthy was reduced when the respondent was male, economically active, in good health, and married or in a common-law relationship. The probability of perceiving a diet as unhealthy was increased for respondents with a college degree and those living in a household that had a male as the sole head. Consuming healthful food and drink reduced the perception of having a poor diet and vice versa, indicating there are possibly connections between food intake, the perception of diet quality and actual diet quality.

Conclusions.

This exploratory analysis established links between perceived diet quality, eating habits and sociodemographic factors. The impact on the perception of diet quality can be negative or positive, depending on the variable under consideration.

Analysis of the Nutritional Value of the Diets Presented in Women's and Sports Magazines before and during the COVID-19 Pandemic

For consumers, among the most important sources of information related to nutrition are popular journals and magazines, including women’s and sports, but the diets presented there may lead to unhealthy weight-control behaviors. The aim of the study was to assess the nutritional value of regular and low-calorie diets presented in Polish women’s and sports magazines before and during COVID-19 pandemic. The study was based on two popular Polish magazines—one women’s magazine and one sports magazine, which regularly present various types of diets. The nutritional value of all the diets published from January 2014 to May 2022 was analyzed. The total number of included single-day menus was n = 119, while for analysis they were stratified based on: type of magazine (published in the women’s magazine n = 41 and in the sports magazine n = 78), year of publication (before the COVID-19 pandemic n = 78 and during n = 41), and type of diet (regular n = 61 and low-calorie n = 58). The analysis included the energy value and nutritional value. For the type of magazine, the diets published in the sports magazine were characterized by a higher intake of fat (p < 0.0001 for intake in grams and in % of energy) and calcium (p = 0.0330), whereas the diets published in the women’s magazine were characterized by a higher intake of carbohydrates (p = 0.0226 for intake in grams, and p = 0.0002 for intake in % of energy) and fiber (p = 0.0163). For the year of publication, the diets published during the COVID-19 pandemic were characterized by a higher intake of protein (p = 0.0166 for intake in grams), sodium (p = 0.0465), calcium (p < 0.0001), vitamin D (p = 0.0197), vitamin B6 (p = 0.0207), and vitamin B12 (p = 0.0277), whereas the diets published before the COVID-19 pandemic were characterized by a higher intake of carbohydrates (p = 0.0243 for intake in % of energy). For the type of diet, the regular diets were characterized by a higher energy value (p = 0.0020), as well as by a higher intake of fat (p = 0.0162 for intake in grams), carbohydrates (p = 0.0390 for intake in grams), mono- and oligosaccharides (p = 0.0084 for intake in % of energy), fiber (p < 0.0001), magnesium (p = 0.0323), iron (p = 0.0307), and vitamin B6 (p = 0.0204). The nutritional value of the diets presented in the Polish women’s and sports magazines was not justified by the type of magazine or type of diet, associated with the target group, which may cause the following of improperly balanced diets. However, the changes in the typical nutritional value of diets presented in the Polish women’s and sports magazines during the COVID-19 pandemic were justified by some specific needs for the prevention and treatment of COVID-19.

Is Better Knowledge about Health Benefits of Dietary Fiber Related to Food Labels Reading Habits? A Croatian Overview

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.

Intergenerational reproduction and self-rated health in Canada

Intergenerational processes in which the socioeconomic status of middle- and upper-class parents is reproduced in their children have been extensively documented by social scientists. We mobilized a unique dataset, the Longitudinal and International Study of Adults (LISA) linked to income data from the Canada Revenue Agency (CRA), to investigate the relevance of intergenerational socioeconomic reproduction for inequalities in self-rated health in a national sample of Canadians aged 25 to 50. We found strong intergenerational elasticities implicating both parental education and parental family income in the acquisition of both personal education and personal family income. Parental education was not significantly associated with self-rated health. Parental family income was significantly associated with self-rated health among women only, partly explained by the socioeconomic status of the women themselves. These results suggest that intergenerational reproduction plays a small role in the generation of high levels of self-rated health among Canadian women but not among Canadian men.

Knowledge and attitudes about influenza and the common cold in Syria post COVID-19: A qualitative study

Background

The common cold and the influenza are common infections that are frequent in the community. In this study, we estimate the level of knowledge regarding those diseases among the Syrian population in the COVID era as it is important to have this knowledge for future health planning and policies.

Methods

A qualitative study was conducted from November to December in 2021. A structured self-administered questionnaire was distributed as Google Forms on social media platforms and hard copies of the questionnaire to patients, their companions, or workers in public hospitals. Chi-square test and Mann Whitney test were used to study the associations between categorical groups.

Results

This study included 13013 participants, 7856 (60.4%) were females, 78.4% were younger than 31 years old, only 3518 (27%) knew that the common cold and the influenza were caused by viruses, 6146 (47.2%) reported that runny nose was the most annoying symptom, 75.6% of the participants believed that antibiotics could kill viruses, and 7674 (58.9%) had fears from symptoms of common cold and influenza because of covid-19. Females were statistically significantly more knowledgeable and had more fears from the infection compared with males.

Conclusion

This study showed a low level of knowledge among the Syrian population. The view of influenza and common cold have changed after COVID as they are now taken more seriously. Many efforts should be made to spread awareness, effective management, and reducing antibiotic misinformation.

•

The public in Syria mostly cannot distinguish between common cold and influenza.

•

They still believe that antibiotics is the treatment of choice for them.

•

COVID-19 has made people more aware and self-conscious of having flu-like symptoms as they can be from having COVID.

Behavior Change Around an Online Health Awareness Campaign: A Causal Impact Study

National Eating Disorders Association conducts a NEDAwareness week every year, during which it publishes content on social media and news aimed to raise awareness of eating disorders. Measuring the impact of these actions is vital for maximizing the effectiveness of such interventions. This study is an effort to empirically measure the change in behavior of users who engage with NEDAwareness content, and compare the detected changes between campaigns in two different years. We analyze a total of 35,895 tweets generated during two campaigns of NEDAwareness campaigns in 2019 and 2020. In order to assess the reach of each campaign, we consider the users participating in the campaigns and their number of followers, as well as retweeting engagement. We use the Linguistic Inquiry and Word Count (LIWC) text modeling and causal impact analysis in order to gauge the change in self-expression of users who have interacted with the NEDAwareness content, compared to a baseline group of users. We further enrich our understanding of the users by extracting gender information from their display names. We find that, despite large media corporations (such as MTV and Teen Vogue) participating in the campaign, it is governmental and nonprofit accounts who are among the accounts that attract the most retweets. Whereas the most influential accounts were well-connected in 2019, the 2020 campaign saw little retweeting between such accounts, negatively impacting the reach of the material. Both campaigns engaged women at around 40% and men 17%, supporting previous research showing women to be more likely to share their experiences with eating disorders. Further, women were more likely to mention other health topics within the 15 days of the intervention, including pregnancy and abortion, as well as depression and anxiety, and to discuss the developing COVID pandemic in 2020. Despite the positive message of the campaign, we find that the users who have engaged with this content were more likely to mention the linguistic categories concerning anxiety and risk. Thus, we illustrate the complex, gender-specific effects of NEDAwareness online health intervention campaign on the continued self-expression of its audience and provide actionable insights for potential improvement of such public health efforts.

Female Endurance Runners Have a Healthier Diet than Males-Results from the NURMI Study (Step 2)

Sex has been recognized to be an important indicator of physiological, psychological, and nutritional characteristics among endurance athletes. However, there are limited data addressing sex-based differences in dietary behaviors of distance runners. The aim of the present study is to explore the sex-specific differences in dietary intake of female and male distance runners competing at >10-km distances. From the initial number of 317 participants, 211 endurance runners (121 females and 90 males) were selected as the final sample after a multi-level data clearance. Participants were classified to race distance (10-km, half-marathon, marathon/ultra-marathon) and type of diet (omnivorous, vegetarian, vegan) subgroups. An online survey was conducted to collect data on sociodemographic information and dietary intake (using a comprehensive food frequency questionnaire with 53 food groups categorized in 14 basic and three umbrella food clusters). Compared to male runners, female runners had a significantly greater intake in four food clusters, including “beans and seeds”, “fruit and vegetables”, “dairy alternatives”, and “water”. Males reported higher intakes of seven food clusters, including “meat”, “fish”, “eggs”, “oils”, “grains”, “alcohol”, and “processed foods”. Generally, it can be suggested that female runners have a tendency to consume healthier foods than males. The predominance of females with healthy dietary behavior can be potentially linked to the well-known differences between females and males in health attitudes and lifestyle patterns.

Meat-Reduced Dietary Practices and Efforts in 5 Countries: Analysis of Cross-Sectional Surveys in 2018 and 2019

BACKGROUND

Diets that reduce reliance on animal-source foods are recommended in some contexts.

OBJECTIVES

This study aimed to compare proportions of respondents who reported following meat-reduced dietary practices (i.e., vegetarian, vegan, or pescatarian diets) and/or making efforts to reduce animal-source foods, and to examine sociodemographic correlates across 5 countries.

METHODS

Online surveys were conducted in November and December 2018 and 2019 with 41,607 adults from Australia (n = 7926), Canada (n = 8031), Mexico (n = 8110), the United Kingdom (n = 9129), and the United States (n = 8411) as part of the International Food Policy Study. Respondents were asked whether they would describe themselves as vegetarian, vegan, or pescatarian, and whether they had made efforts to consume less red meat, less of all meats, or less dairy in the past year. Logistic regressions examined differences in the likelihood of each behavior between countries and sociodemographic subgroups.

RESULTS

Approximately 1 in 10 respondents reported following a vegetarian, vegan, or pescatarian diet, ranging from 8.6% (Canada) to 11.7% (UK). In the past 12 months, the proportions of respondents who reported efforts to consume less red meat ranged from 34.5% (Australia) to 44.4% (Mexico), less of all meats ranged from 27.9% (US) to 35.2% (Mexico), and to consume less dairy ranged from 20.6% (UK) to 41.3% (Mexico). Respondents were more likely to report efforts to consume less animal-source products in 2019 compared to 2018 in most countries. Sociodemographic patterns varied by country; in general, women, those with higher education levels, and those in minority ethnic groups were more likely to report following meat-reduced dietary practices or efforts to consume fewer animal-source products.

CONCLUSIONS

Nearly half of respondents reported following a meat-reduced diet or efforts to reduce animal-source products, with differences between countries and population subgroups. Population-level approaches and policies that support meat reduction may further reduce consumption of animal-source products.

Consumer Understanding of the Australian Dietary Guidelines: Recommendations for Legumes and Whole Grains

Dietary guidelines provide evidence-based guidance for healthy individuals to improve dietary patterns, although they are most often based on individual foods or food groups. Legumes are a class of food included in current Australian Dietary Guidelines (ADG), mentioned in two of the five food groups, as a vegetable and as an alternative to meat. Whole grain consumption is encouraged in ADG via the statement focused on cereal grains due to their health-promoting properties. Despite their prominence in guidelines, average legume and whole grain consumption in Australia remains lower than recommendations outlined in the ADG. This exploratory study aimed to understand consumer perspectives of wording utilised in dietary guidelines specifically focused on legumes and whole grains. Based on the analysis, there was a significant preference for the statement “each day, consume at least one serve of legumes either as a serve of vegetables or as an alternative to meat” (p < 0.05), which provides a specific frequency and quantification for legume consumption. For whole grain, the significantly preferred statement was “choose whole grain products over refined grains/white flour products whenever you can” indicating a less prescriptive option. Effective messaging in guidelines could consider greater specificity regarding frequency, quantity and quality of foods recommended. This exploratory study suggests an improvement in the adoption and consumption of legumes and whole grains in the Australian diet may be better facilitated through consumer-tested messaging.

Analysis of Self-Regulation of Eating Behaviors within Polish Adolescents' COVID-19 Experience (PLACE-19) Study

The self-regulation of eating behaviors (suppression of behavioral short-term impulse to consume food products in the interest of pursuing long-term weight goals), has been an important determinant for adopting a healthy lifestyle in the period of the COVID-19 pandemic in adults, but there have been no such studies conducted in the population of adolescents in this period. The aim of the presented study is to analyze self-regulation of eating behaviors in the population-based sample of Polish adolescents within the Polish Adolescents’ COVID-19 Experience (PLACE-19) Study. The Self-Regulation of Eating Behavior Questionnaire (SREBQ) was used to assess self-regulation of eating behaviors in the studied population of 1126 Polish adolescents (818 females and 308 males), aged 15−20, recruited based on a random quota sampling within a national sample. Based on the screening questions of the SREBQ, 145 individuals were excluded from the analysis. The participants of the study were categorized based on their gender, body mass index, body mass index change during the COVID-19 pandemic, and food products declared as tempting. The major factors associated with SREBQ score were body mass index change and tempting food products. The respondents losing weight during the COVID-19 pandemic were characterized by a higher SREBQ score than those maintaining stable body mass or gaining weight (3.4 vs. 3.2 vs. 3.2; p = 0.0001). The respondents declaring both sweet and salty food products as tempting were characterized by a lower SREBQ score than those declaring only sweet, only salty, or declaring no tempting products (3.2 vs. 3.4 vs. 3.4 vs. 3.4; p < 0.0001). The major factors associated with SREBQ categories were gender, body mass index change, and tempting food products. A higher share of respondents characterized by a high self-regulation of eating behaviors was observed for males than for females (27.4% vs. 18.8%; p = 0.0142); for respondents losing weight during the COVID-19 pandemic than for respondents gaining weight (25.9% vs. 15.5%; p = 0.0423); as well as for respondents declaring no tempting products than those declaring both sweet and salty food products (38.3% vs. 18.2%; p < 0.0001). It was concluded that the self-regulation of eating behaviors in adolescents is closely associated with food products perceived as tempting by them, as well as with gender. During the COVID-19 pandemic, the low self-regulation of eating behaviors was a significant determinant of the body mass gain. Taking this into account, female adolescents characterized by a low self-regulation of eating behaviors especially should be subjected to a dedicated intervention program to prevent overweight and obesity.

Health Behaviors of Austrian Secondary School Teachers and Principals at a Glance: First Results of the From Science 2 School Study Focusing on Sports Linked to Mixed, Vegetarian, and Vegan Diets

Lifestyle behaviors are key contributors to sustainable health and well-being over the lifespan. The analysis of health-related behaviors is crucial for understanding the state of health in different populations, especially teachers who play a critical role in establishing the lifelong health behaviors of their pupils. This multidisciplinary, nationwide study aimed to assess and compare lifestyle patterns of Austrian teachers and school principals at secondary levels I and II with a specific focus on physical activity and diet. A total number of 1350 teachers (1.5% of the eligible Austrian sample; 69.7% females; 37.7% from urban areas; mean age: 45.8 ± 11.4 years; mean BMI: 24.2 ± 4.0) completed a standardized online survey following an epidemiological approach. Across the total sample, 34.4% were overweight/obese with a greater prevalence of overweight/obesity in males than females (49.5% vs. 29.2%, p < 0.01) and rural vs. urban environments (35.9% vs. 31.3%). Most participants (89.3%) reported a mixed diet, while 7.9% and 2.9% were vegetarians and vegans, respectively. The average BMI of teachers with mixed diets (24.4 ± 4.0 kg/m2) was significantly higher than vegetarians (23.1 ± 3.2 kg/m2) and vegans (22.7 ± 4.3 kg/m2). Vegans reported a lower level of alcohol intake (p < 0.05) among dietary groups. There was no between-group difference in smoking (p > 0.05). The prevalence of engagement in regular physical activity was 88.7% for leisure-time sports/exercises and 29.2% for club sports. Compared with the previous reports on general populations, the present data suggest an acceptable overall health status among Austrian teachers.

Level of cardiovascular disease knowledge, risk perception and intention towards healthy lifestyle and socioeconomic disparities among adults in vulnerable communities of Belgium and England

Background

The burden of cardiovascular diseases (CVDs) greatly varies between and within countries. Low- and middle-income countries (LMICs) and vulnerable communities of high-income countries (HIC) share disproportionately higher burden. Evidence is limited on the level of CVD knowledge and risk perception in vulnerable communities. Hence, in this study, we assessed the level of CVD knowledge, risk perception and change intention towards physical activity and healthy diet among vulnerable communities in Antwerp, Belgium and Nottingham, England. Furthermore, we investigated the socioeconomic disparities particularly in the Antwerp setting.

Method

A cross-sectional study was performed among 1,424 adults (958 in Antwerp and 466 in Nottingham) aged 18 or older among selected vulnerable communities. Districts or counties were selected based on socioeconomic and multiple deprivation index. A stratified random sampling was used in Antwerp, and purposive sampling in Nottingham. We determined the level of CVD knowledge, risk perception and intention towards a healthy lifestyle in Antwerp and Nottingham using a percentage score out of 100. To identify independent socioeconomic determinants in CVD knowledge, risk perception, intention to PA and healthy diet, we performed multilevel multivariable modeling using the Antwerp dataset.

Results

The mean knowledge percent score was 75.4 in Antwerp and 69.4 in Nottingham, and only 36.5% and 21.1% of participants respectively, had good CVD knowledge (scored 80% or above). In the multivariable analysis using the Antwerp dataset, level of education was significantly associated with (1) CVD knowledge score (Adjusted β = 0.11, 95%CI: 0.03, 0.18), (2) risk perception (0.23, 95%CI: 0.04, 0.41), (3) intention to physical activity (PA) (0.51, 95%CI: 0.35, 0.66), and (4) healthy diet intention (0.54, 95%CI: 0.32, 0.75). Furthermore, those individuals with a higher household income had a better healthy diet intention (0.44, 95%CI: 0.23, 0.65). In contrast, those who were of non-European origin scored lower on intention to have a healthy diet (-1.34, 95%CI:-2.07, -0.62) as compared to their European counterparts. On average, intention to PA was significantly higher among males (-0.43, 95%CI:-0.82, -0.03), whereas females scored better on healthy diet intention (2.02, 95%CI: 1.46, 2.57).

Conclusions

Knowledge towards CVD risks and prevention is low in vulnerable communities. Males have a higher intention towards PA while females towards a healthy diet and it also greatly varies across level of education. Moreover, those born outside Europe and with low household income have lower healthy diet intention than their respective counterparts. Hence, CVD preventive interventions should be participatory and based on a better understanding of the individuals’ socioeconomic status and cultural beliefs through active individual and community engagement.

Challenges for Upcycled Foods: Definition, Inclusion in the Food Waste Management Hierarchy and Public Acceptability

Upcycled foods contain unmarketable ingredients (e.g., damaged food produce, by-products and scraps from food preparation) that otherwise would not be directed for human consumption. Upcycled food is a new food category and thus faces several challenges, such as definition development, inclusion in the food waste management hierarchy and public acceptability. This review provides an overview of these three challenges. The upcycled food definitions have been developed for research, food manufacturers, and multi-stakeholders use. Thus, there is a need for a consumer-friendly definition for the general public. A simplified definition is proposed to introduce these foods as environmentally friendly foods containing safe ingredients that otherwise would not have gone to human consumption such as damaged food produce, by-products and scraps from food preparation. Moreover, an updated version of the food waste management hierarchy has been proposed by including the production of upcycled foods as a separate waste management action that is less preferable than redistribution but more favourable than producing animal feed. Furthermore, consumer sociodemographic characteristics and beliefs, as well as food quality cues and attributes, were identified as crucial factors for the public acceptability of these foods. Future research should address these challenges to facilitate the introduction of upcycled foods.

Artificial Intelligence in Functional Food Ingredient Discovery and Characterisation: A Focus on Bioactive Plant and Food Peptides

Scientific research consistently demonstrates that diseases may be delayed, treated, or even prevented and, thereby, health may be maintained with health-promoting functional food ingredients (FFIs). Consumers are increasingly demanding sound information about food, nutrition, nutrients, and their associated health benefits. Consequently, a nutrition industry is being formed around natural foods and FFIs, the economic growth of which is increasingly driven by consumer decisions. Information technology, in particular artificial intelligence (AI), is primed to vastly expand the pool of characterised and annotated FFIs available to consumers, by systematically discovering and characterising natural, efficacious, and safe bioactive ingredients (bioactives) that address specific health needs. However, FFI-producing companies are lagging in adopting AI technology for their ingredient development pipelines for several reasons, resulting in a lack of efficient means for large-scale and high-throughput molecular and functional ingredient characterisation. The arrival of the AI-led technological revolution allows for the comprehensive characterisation and understanding of the universe of FFI molecules, enabling the mining of the food and natural product space in an unprecedented manner. In turn, this expansion of bioactives dramatically increases the repertoire of FFIs available to the consumer, ultimately resulting in bioactives being specifically developed to target unmet health needs.

Interactions between parental and personal socioeconomic resources and self-rated health: Adjudicating between the resource substitution and resource multiplication theories

A small body of research has documented intriguing findings, mostly from the United States but also from Europe, which suggest that the positive health effects of socioeconomic resources in adulthood may be conditioned by socioeconomic circumstances in childhood. There are two competing theories in this literature. The first contends that socioeconomic resources have a stronger effect on adult health for people from disadvantaged backgrounds because socioeconomic resources in adulthood substitute or compensate for a paucity of health-related resources earlier in life. The second contends that socioeconomic resources have a stronger effect on adult health for people from advantaged backgrounds because socioeconomic resources in adulthood compound or multiply the health effects of socioeconomic resources earlier in life. We used survey data from the 2012 Longitudinal and International Study of Adults linked to current and historical income data from the Canada Revenue Agency to investigate interactions between parental and personal socioeconomic resources - education and income, treated separately - as predictors of self-rated health in a sample of Canadians aged 25 to 50. Consistent with the resource multiplication theory, we found that the presumed benefits of personal family income for self-rated health were stronger for women from wealthier backgrounds than for women from poorer backgrounds. We found no evidence to support either theory among men. Overall, none of the interactions involving the education of parents or their adult children reached statistical significance. Our results are indicative of the importance of distinguishing between education and income for adults and their parents when adjudicating between these two theories.

The Use of Demographics and Psychographics to Study Product Effects with Nutrient Supplements: Exploratory Multi-Country Data

Demographics and psychographics are used to study the influence of different consumers on product effects in food development and testing. Demographics have a longer history and are routinely used in most research; psychographics are more recent, raising the question of whether they add to research on food products. The research presented here represents extensive exploratory data that demonstrate that both demographic measures and psychographic measures add to our understanding of consumer's liking ratings for nutrient supplements. The results are discussed in the context of broader research on a range of food products. In addition, the research reported here was conducted in four different countries, demonstrating many country effects. Finally, tests were conducted with users of the products, lapsed users of the product, and users of other nutrient supplements (non-users), and this led to many differences in product testing. These results further suggest that age and gender are not the only demographic variables to be studied, along with psychographic variables. The psychographic variables should be selected for a particular product category under investigation, as effects of specific psychographic measures vary for product categories. Specific variables do not fit all products for both demographics and psychographics.

Consumer Profile and Product Knowledge Affect the Usefulness of a Quality Label as a Tool to Differentiate a Product: A Chilean Survey

Quality labels are useful tools to differentiate food products, but only if consumers recognise them and associate them with specific characteristics. An online survey was conducted to investigate whether Chilean consumers knew about Novillo de Osorno, for which a quality label is being developed. The survey was divided into five blocks: lifestyles, meat consumption and purchase habits, meat choice behaviour, knowledge about Novillo de Osorno, and consumers' socio-demographic information. The place of residence and consumer gender, age, or income were important cues in defining consumers' lifestyles, meat consumption and purchase habits. Respondents could be grouped into three main groups: 1. Younger people: urban with medium-high incomes, which search only for pleasure; 2. Foodies uninvolved and Females uninvolved: females with the highest income level that chose food for nutritional reasons; and 3. Traditional people: men older than 55 with low incomes, living in the Northern areas and interested in taste and in the meat's origin. Nearly 60% of respondents had never heard about Novillo de Osorno. Hence, the supply chain has an opportunity to extend the market. Since price and confidence in the origin are important cues, they must be considered in the design of promotion strategies.
