Factors influencing healthy eating habits among college students: an application of the health belief model

Health Belief Model Predicts Likelihood of Eating Nutrient-Rich Foods among U.S. Adults

Despite decades of messaging, most Americans still consume excess fats and sugars, but inadequate fiber, potassium, and calcium. Nutrient-rich foods (NRFs) have a high density of favorable nutrients related to calories. Choosing NRFs could lower risk of nutrition-related chronic diseases and aid in their control. We hypothesized that having greater knowledge of NRFs, the presence of a nutrition-related chronic disease or risk factor, and positive Health Belief Model (HBM) views would be predictive of the likelihood of eating NRFs. Through a national online survey panel, 976 adults aged 18-80 completed demographic, health, NRF knowledge, attitudes, and HBM construct questions. Participants were 77% White, 52% women, and 55% had a nutrition-related disease or risk factor. Multivariable HBM scales were generated by theory, principal components, and reliability analysis. NRF knowledge was significantly higher for women, Whites, households without children, and persons without a nutrition-related disease (all p ≤ 0.015). 'Likelihood of eating NRFs' was significantly higher for persons with a nutrition-related disease, Whites, married participants, main food shoppers, and households with children (all p ≤ 0.022). Regressing demographic and HBM constructs on the 'likelihood of eating NRFs' resulted in R2 of 0.435. Nutrition-related disease and HBM constructs of self-efficacy, perceived benefits, and cues to action were predictive of the likelihood of eating NRFs, but higher NRF knowledge was negatively associated.

"Not me!": Optimistic bias and college students' perceived susceptibility, severity, benefits, and self-efficacy in following COVID-19 preventive guidelines

Objective The COVID-19 pandemic has created unprecedented challenges for university administrators and health professionals to keep doors open and students safe. Optimistic bias and the Health Belief Model serve as foundations for understanding students' perceived susceptibility and severity for contracting the virus and their perceived benefits and self-efficacy for following prevention recommendations. Participants: A total of 1,773 undergraduate and graduate students from a large mid-western university participated. Methods: Students were emailed an online survey examining their perceptions and knowledge of COVID-19 and their adherence to recommended preventive measures. Results: Almost one-half of students do not think they will get COVID-19 but said their friends are at risk. The majority are following most Centers for Disease Control and Prevention recommendations and understand the perceived benefits of doing so. Conclusions: Results could aid university officials in developing effective COVID-19 messages that could lead to reductions in cases numbers, deaths, and spread of the virus.

Adherence to the Mediterranean Diet and its association with sustainable dietary behaviors, sociodemographic factors, and lifestyle: a cross-sectional study in US University students

BACKGROUND

Promoting healthy and sustainable diets is increasingly important and the Mediterranean Diet (MD) has been recognized as an appropriate example that can be adapted to different countries. Considering that the college years are the time when US young adults are most likely to adopt unhealthy eating habits, the present study assessed adherence to the MD and the sustainability of dietary behaviors in a nationally representative sample of US university students, aiming to identify crucial levers for improving their eating behaviors.

METHODS

MD adherence and the adoption of healthy and sustainable dietary patterns were assessed through the KIDMED and the Sustainable-HEalthy-Diet (SHED Index questionnaires, respectively, administered through an online survey that also included sociodemographic and behavioral questions. Non-parametric and logistic regression analyses were performed.

RESULTS

A sample of 1485 participants (median (IQR) age 21.0 (19.0-22.0); 59% women) correctly completed the survey. A medium adherence to the MD was the most prevalent (47%). According to multivariate logistic regression analysis, the likelihood of being more compliant with the MD increased when meeting physical activity recommendations, having a high SHED Index score, having the willingness to purchase and eat healthy and sustainable dishes, eating ultra-processed plant-based meat alternatives foods daily, and regularly attending the university canteen.

CONCLUSIONS

Encouraging dietary patterns rich in plant-based foods and with a moderate intake of animal products is crucial to increasing the adoption of healthy and sustainable diets, and university dining services represent a suitable setting to build a supportive environment that educates students on human and planetary health.

From plate to profile: investigating the influence of dietary habits and inactive lifestyle on lipid profile in medical students at clerkship

BACKGROUND

Dietary habits have a strong association with body lipid levels and hyperlipidemia increases the risk of cardiovascular and metabolic diseases. Dietary habits have been a major concern among medical students due to busy schedules and demanding tasks. This study was designed to know the dietary habits and lifestyle of medical students and its association with their lipid profile.

METHODS

We recruited 120 medical students at clerkship of the age of 18 and above. Weekly dietary habits were evaluated by an 18-item questionnaire. Five ml blood was drawn from the students and lipid profiles were measured at Dow Diagnostic Research and Reference Laboratory (DDRRL). Data was analyzed by SPSS V.22.

RESULTS

We found 70% of students were not involved in any physical activity throughout the week. Only 15.83% were following a regular diet plan. 65% of students were eating junk food for more than 3 days a week in their weekly diet. Moreover, 19.2%, 39.2%, 32.5%, and 25.84% of students were having their total cholesterol, triglycerides, HDL, and LDL levels above the optimum ranges respectively which were frequently found in students of final year (p < 0.05). There was high total cholesterol and LDL in males as compared to females (p value < 0.05). Total cholesterol and LDL were associated with skipped meal, use of junk food and carbonated drinks for more than 3 days a week (p < 0.05).

CONCLUSION

There was a notable number of students with poor dietary habits, inactive lifestyle and lipid levels above the optimum ranges defined by American Heart Association (AHA) that have an association with dietary habits. This is alarming and can impact the health of future healthcare workers. There is a need to investigate the factors and remedies to help medical students to follow a healthy diet and a healthy lifestyle.

Utilisation of the health belief model to study the behavioural intentions relating to obesity management among university students: a cross-sectional study

BACKGROUND

Overweight and obesity are excessive fat accumulations linked with many health problems, including heart diseases, type 2 diabetes and cancer. Multiple studies have demonstrated that beliefs about overweight, obesity and self-efficacy play essential roles in the success of interventions for obesity management.

OBJECTIVES

This study aimed to identify the perceptions of university students of overweight and obesity using the health belief model (HBM) and to analyse their association with the body mass index (BMI) categories of the students.

DESIGN

A cross-sectional questionnaire-based study and a multistage sampling technique were used to ensure the recruitment of students from selected colleges of Jazan University-Saudi Arabia.

SETTING

Six colleges of Jazan University were randomly selected to ensure equal representation of health sciences, sciences and humanities colleges.

PARTICIPANTS

A total of 579 students completed an online survey between January and April 2023.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome measures were demographic characteristics and HBM constructs. Secondary outcome measures were behavioural intentions relating to obesity management.

RESULTS

This study demonstrated that gender and self-reported family history of obesity were significantly correlated with the BMI categories of the students (p <0.001). Students in the underweight category showed the highest mean score for perceived severity (3.62 ±0.08). Perceived self-efficacy in exercise and diet was significantly associated with BMI categories, with adjusted ORs of 2.82 (2.10 to 3.79) and 1.51 (1.09 to 2.09), respectively. Perceived barriers to healthy eating and regular physical activity were significantly related to the behavioural intentions of obesity management. Multivariate logistic regression showed that perceived severity, perceived cues to action, perceived barriers and self-efficacy in dieting and exercise were significant predictors of behavioural intentions for the management of obesity.

CONCLUSION

This study underscores the need for tailored health promotion strategies that consider the perceptions and beliefs of people about the management of obesity.

Factors influencing baby boomers' intention to choose a dish featuring plant-based meat alternatives (PBMA) at a restaurant: Findings from an online panel study

The purpose of this study is to examine the psychosocial determinants of baby boomers'-born between 1946 and 1964- intention to choose a menu item featuring plant-based meat alternatives (PBMA) when dining out. The specific objectives are as follows: 1) to identify the baby boomer generation's health-related perceptions about PBMA, and 2) to examine the factors that influence baby boomers' intention to choose a dish featuring PBMA at a restaurant. A total of 174 responses obtained using the Qualtrics panel were analyzed with content analysis and partial least squares structural equation modeling (PLS-SEM). The findings identified various underlying perceptions of baby boomers toward PBMA, such as perceived health outcomes, perceived availability, and willingness to purchase. Furthermore, subjective norm, cues to action, and self-identity were found to be significant predictors of the intention to choose a menu item featuring PBMA when dining out. Theoretical and practical implications are discussed.

Gaming with health misinformation: a social capital-based study of corrective information sharing factors in social media

Correction is an important tool to reduce the negative impact of health misinformation on social media. In the era of "I share, therefore I am" social media, users actively share corrective information to achieve the "anti-convincing" effect of health misinformation. Focusing on the local Chinese context, this study constructs a structural equation model using social capital as a mediating variable to explore whether usage of Chinese users' social media can promote corrective information sharing by influencing the structural, cognitive, and relational dimensions of social capital and the role of health literacy in corrective information sharing. It was found that social media use did not significantly affect corrective information share willingness but significantly influenced share willingness through social interaction connections, trust, and shared experiences, and share willingness significantly influenced sharing behavior. The moderating effect showed that health literacy played a significant moderating effect in the influence of corrective information share willingness on sharing behavior. This study introduces the three dimensions of social capital at the theoretical level and finds that users will share corrective information for the purpose of social capital accumulation. It also provides empirical evidence for specific practices, including improving users' health literacy and actively mobilizing them to participate in the blocking and management of health misinformation in social media.

Exploring students' perception of subjective food literacy: A model of educational practice

Introduction

Latest research showed that lower levels of food literacy led to poorer health outcomes and highlighted the importance of nutrition education to improve food literacy for the population. Although evidence at the global level exists, the scientific literature on food literacy in Romania is scarce; therefore, this article aims to explore the perception of subjective food literacy as an outcome of an educational model in a sample of university students from Romania.

Methods

The present study used a qualitative inductive approach using focus groups to explore the results from an educational "learning-by-doing" model regarding the perception of subjective food literacy. The sample consisted of 64 second-year students who participated in a class taught by one of the authors between October 2019 and February 2020 and later agreed to participate in the focus groups. All focus groups were audiotaped following participants' permission and transcribed verbatim. Data was analyzed with the QSR Nvivo 12 Pro software package using an inductive thematic analysis.

Results

Several themes and sub-themes emerged from the focus groups discussing prior information of participants regarding nutrition, change in nutrition knowledge (information about plant protein, information about soy and soy products, information about sugar and its effects on health, and additional nutrition information), modified perception of nutrition and food, dietary habits, short-term behavior changes, and aspects that helped them to have more information about nutrition (construction of the health campaign, pre-testing materials, and support offered by the professors). All participants reported acquiring new information about food and nutrition, modified perceptions about nutritional habits, and even reported short-term behavioral change as an outcome of the educational model.

Conclusions

Educational models using a learning-by-doing approach and combining formal and non-formal education can potentially affect students' subjective food literacy. Future research should explore university students' food literacy using evidence-based educational models.

Eating behaviors and the perceived nutrition environment among college students

Objectives: To assess eating behaviors and identify whether there is an association between eating behaviors and the perceived nutrition environment among college students. Participants: College students (n = 180) actively living on campus during the 2019-2020 academic school year. Methods: Cross- sectional study utilizing the validated NEMS-P survey tool to collect all data. A multivariate logistics regression was used to assess the association between eating behaviors and the perceived nutrition environment. Results: Statistically significant association noted between perceived higher cost of healthy eating and decreased consumption of fruit (p = .027), availability of nutrition information (healthy eating signs) and increased vegetable and fruit consumption (p = .018, p = 0.010) and increased ease of purchasing fruits and vegetables and increased consumption (p = 0.037). Conclusion: The campus nutrition environment can provide students the opportunity to learn about and practice healthy eating through available foods and beverages, nutrition education and signs that encourage healthy eating throughout the campus.

Nourishing Conversations: Using Motivational Interviewing in a Community Teaching Kitchen to Promote Healthy Eating via a Food as Medicine Intervention

It is well known that dietary choices impact both individual and global health. However, there are numerous challenges at the personal and systemic level to fostering sustainable healthy eating patterns. There is a need for innovative ways to navigate these barriers. Food as Medicine (FM) and Culinary Medicine (CM) are approaches to helping individuals achieve healthier diets that also recognize the potential to alleviate the burden of chronic diseases through healthy eating. Teaching kitchens, which offer an interactive environment for learning nutrition and cooking skills, are valuable educational tools for FM and CM interventions. Motivational interviewing (MI), a type of person-centered counseling, facilitates behavior change and may enhance FM and CM programs involving teaching kitchens. In this commentary, we share our experience with using MI in a community-based CM program at a teaching kitchen. In demonstrating our application of MI principles, we hope to offer an additional strategy for improving dietary quality and delivering nutrition education.

Addressing nutritional issues and eating behaviours among university students: a narrative review

University life is a critical period for establishing healthy eating habits and attitudes. However, university students are at risk of developing poor eating habits due to various factors, including economic conditions, academic stress and lack of information about nutritional concepts. Poor diet quality leads to malnutrition or overnutrition, increasing the risk of preventable diseases. Food environments on university campuses also play a significant role in shaping the dietary habits of students, with the availability of and accessibility to healthy food options being important factors influencing food choices and overall diet quality. Disordered eating habits and body dissatisfaction are prevalent among university students and can lead to eating disorders. Income and living arrangements also influence dietary habits, with low household income and living alone being associated with unhealthy eating habits. This study is a narrative review that aimed to address nutritional issues and eating behaviours, specifically among university students. We investigated the eating behaviours of university students, including their dietary patterns, food choices and food environments. The objective of this review was to provide insights into the nutritional issues and eating behaviours of university students, with the aim of identifying target areas for intervention to improve the overall health and wellbeing among college students. University food environments need to be restructured to promote healthy eating, including the availability, accessibility, affordability and labelling of healthy foods, and policies to limit the availability of unhealthy foods and drinks on campus.

Factors influencing consumers' intention to donate blood: A South African perspective

The objective of this study was to determine the factors influencing consumer intention to donate blood in an emerging market setting. A quantitative research design was followed that entailed the collection of data from 308 non-donor respondents, using a self-administered online questionnaire. The conceptual model and hypotheses were analysed statistically, using SPSS to conduct reliability analysis, correlation analysis, and multiple regression analysis. The findings revealed that awareness of consequences, ascription of responsibility, and personal norms had a positive and significant influence on consumers' intention to donate blood. Ascription of responsibility was the largest influencer of personal norms towards blood donation.

Who has a high level of food literacy, and who does not?: a qualitative study of college students in South Korea

BACKGROUND/OBJECTIVES

Unhealthy food choices among young adults are common globally, and the incidence of chronic diseases, such as obesity, is rising. Food literacy (FL) is important for improving and maintaining individual health in a rapidly changing food environment and can form the basis for following a sustainable diet. Therefore, it is essential to improve FL among young adults, particularly college students, who are in the formative years of their lifelong food habits. This study examined the facilitators and barriers of FL and related dietary behavior among college students in South Korea.

SUBJECTS/METHODS

This study recruited 25 college students with different residence types using convenience and snowball sampling. In-person, telephone, and video interviews were conducted from March to November 2021. The interview data were analyzed using framework analysis based on the socio-ecological model.

RESULTS

At the individual level, prior good experiences with food were the most frequently mentioned facilitator. In contrast, the major barriers were a lack of knowledge, financial hardship, irregular schedules, and academic stress. At the interpersonal level, the influences of family and peers, such as early exposure to healthy eating habits and opportunities to have easy accessibility to farms and farming, are major facilitators, but the lack of a sense of community was the major barrier. At the environmental level, the major barriers were unfavorable food environments at home and in neighborhoods, such as the absence of kitchens in housing and large packaging of produce at markets.

CONCLUSIONS

Many factors affected the students' FL and related healthy eating practices. These findings suggest that a campus-based FL program should be developed by reflecting on these facilitators and barriers.

Adherence to the Mediterranean diet and depression, anxiety, and stress symptoms in Chilean university students: a cross-sectional study

This study aims to determine the association of adherence to the Mediterranean diet and its food groups with depressive symptoms in Chilean university students. The study design was cross-sectional. A total of 934 first-year students at a Chilean public university completed a self-report questionnaire. To assess adherence to Mediterranean diet, an index validated in Chile (Chilean-MDI) was used, and depression, anxiety, and stress symptoms were assessed using the Depression Anxiety and Stress Scale (DASS-21). Logistic regression models were used to analyze the association of adherence to Mediterranean diet and its food groups with depression, anxiety, and stress symptoms adjusted for the main confounders. Students with moderate and high adherence to Mediterranean diet showed lower odds of depression [DASS-21 > 5, odds ratio (OR) = 0.64; 95% confidence interval (95%CI): 0.47-0.88] than those with low adherence to Mediterranean diet. The consumption of 1-2 servings/day of vegetables (OR = 0.63; 95%CI: 0.43-0.92), > 2 servings/week of nuts (OR = 0.41; 95%CI: 0.21-0.80), 1-2 servings/day of fruits (OR = 0.60; 95%CI: 0.42-0.85), 1-2 servings/week of fish and seafood (OR = 0.67; 95%CI: 0.48-0.94), and 1/2-3 units/week of avocado (OR = 0.67; 95%CI: 0.48-0.93) showed low odds of depressive symptoms. The consumption of whole grains and cereals (> 2 servings/day) (OR = 1.63; 95%CI: 1.02-2.61) showed the opposite association. Adherence to Mediterranean diet and consumption of fruits, vegetables, nuts, avocado, fish, and seafood are associated with a lower likelihood of depression in Chilean university students. New policies and educational strategies are recommended to improve diet quality and the mental health of the entire university community.

Depression deconstructed: Wearables and passive digital phenotyping for analyzing individual symptoms

Wearable technology enables unobtrusive collection of longitudinally dense data, allowing for continuous monitoring of physiology and behavior. These digital phenotypes, or device-based indicators, are frequently leveraged to study depression. However, they are usually considered alongside questionnaire sum-scores which collapse the symptomatic gamut into a general representation of severity. To explore the contributions of passive sensing streams more precisely, associations of nine passive sensing-derived features with self-report responses to Center for Epidemiologic Studies Depression (CES-D) items were modeled. Using data from the NetHealth study on N=469 college students, this work generated mixed ordinal logistic regression models to summarize contributions of pulse, movement, and sleep data to depression symptom detection. Emphasizing the importance of the college context, wearable features displayed unique and complementary properties in their heterogeneously significant associations with CES-D items. This work provides conceptual and exploratory blueprints for a reductionist approach to modeling depression within passive sensing research.

Analysis of the factors that influence preschool children eating behavior by applying the health belief model: Seoul and Gyeonggi Province

BACKGROUND/OBJECTIVES

This study explores the parental characteristics that affect the eating behaviors of preschool children. The nutrition quotient for preschool children (NQ-P) tool was applied to measure the eating behaviors of preschool children, and the relationship between parents' health beliefs and children's eating behaviors was investigated by applying the health belief model.

MATERIALS/METHODS

In August 2018, a self-administered online survey was conducted on a sample of parents of children aged 3 to 5 years living in the Seoul and Gyeonggi area. A total of 248 respondents were analyzed via descriptive statistics, one-way ANOVA, Tukey's multiple comparison test, Pearson correlation analysis, and multiple regression analysis.

RESULTS

The eating behaviors of preschool children significantly differed based on parents' education level and monthly income (P < 0.01). Among the factors of the health belief model, "perceived benefit" had the highest score at 4.37 points. The multiple regression analysis confirmed that parents' "self-efficacy" raised the NQ-P scores (β = 0.175, P < 0.05), balance scores (β = 0.204, P < 0.01), and environment scores of preschool children (β = 0.149, P < 0.05). The study results showed that if parents are educated on healthy eating habits and their level of self-efficacy for healthy eating practices increases, the formation of correct eating behaviors for preschool children is more likely.

CONCLUSION

This study provides preliminary data to develop an education program for parents to understand proper eating behaviors for their children and may help form healthy eating habits and encourage the healthy growth of preschool children.

A model of health-related quality of life during COVID-19 pandemic: the role of food customer loyalty and affordability

Purpose

This research aims to test the simultaneous effects of the perceived threat of COVID-19, e-health literacy, e-health access barrier, loyalty toward healthy foods in general, loyalty toward functional foods, the affordability of healthy foods in general and the affordability of functional foods on health-related quality of life (HrQoL) during the COVID-19 pandemic.

Design/methodology/approach

A survey with 400 respondents in Banten, Indonesia, was performed. The data were analyzed using multiple regression analysis.

Findings

The results of the research showed that HrQoL during the COVID-19 pandemic was positively affected by e-health literacy and the affordability of healthy foods in general while negatively affected by the e-health access barrier, the perceived threat of COVID-19 and loyalty toward healthy foods in general. Furthermore, HrQoL was not influenced by loyalty toward and affordability of functional foods.

Research limitations/implications

This research was conducted in Banten. Due to the operational limitations during the COVID-19 pandemic, this research used a purposive sampling technique. Therefore, the next research should retest the model in different contexts and locations.

Practical implications

To improve HrQoL during the COVID-19 pandemic, citizens need to be educated on finding and utilizing credible online health information during the COVID-19 pandemic. Governments and health service providers should also strive to offer ease of access to credible online health information. Furthermore, the affordability of healthy foods, in general, should be managed well.

Originality/value

A few studies on HrQoL during COVID-19 pandemic were performed. However, there is a lack of paper that examines the role of food customer loyalty and affordability in a model of HrQoL during the COVID-19 pandemic. To the best of the authors’ knowledge, this paper is the first that involved and tested the role of food customer loyalty and affordability in a model of HrQoL during the COVID-19 pandemic.

Understanding topical fluoride hesitancy and refusal behaviors through the extended parallel process model and health belief model

OBJECTIVES

Topical fluoride helps prevent dental caries. However, many caregivers are hesitant about topical fluoride for their children and may refuse it during clinic visits. In this qualitative study, we assessed the relevance of the extended parallel process model (EPPM) and health belief model (HBM) in caregivers' decision-making about topical fluoride.

METHODS

We interviewed 56 fluoride-hesitant or fluoride-refusing caregivers using a semi-structured interview script that included questions based on select constructs from the EPPM (perceived severity, susceptibility, response efficacy) and HBM (perceived benefits and consequences). Two team members conducted a thematic analysis of the interview data.

RESULTS

Most caregivers acknowledged the severity of cavities but did not believe their child was susceptible. Caregivers also understood the general benefits of fluoride in preventing tooth decay, but reported low response efficacy of fluoride for their children especially compared to the other ways of reducing caries risk like reducing sugar intake and toothbrushing. Many caregivers had concerns about topical fluoride, especially regarding safety, with the potential consequences of fluoride outweighing its benefits.

CONCLUSION

Our findings were generally consistent with the EPPM and HBM, which appear to be relevant in understanding fluoride hesitancy behaviors. Additional research is needed on ways to improve provider communications about topical fluoride with caregivers.

Determinants of Beijing Residents' Intentions to Take Protective Behaviors against Smog: An Application of the Health Belief Model

Severe smog, a form of air pollution, has become a threat to public health in Beijing, China. To examine Beijing residents' protective behavioral intentions against smog, we proposed a conceptual model, which applies the health belief model (HBM) and specifies the roles of three distal predictors: exposure to news, discussion, and worry. The proposed model was tested in the context of protective behavioral intentions (i.e., intention to wear facemask & intention to use air purifier). Data were collected from Beijing residents during the period from 2/27 to 3/7 in 2017. Structural-equation-modeling (SEM) analyses of valid cases (N = 523) found support for the health belief model regarding the positive effects of perceived threat, perceived benefit, and perceived self-efficacy on intention to wear facemask or intention to use air purifier. Perceived barrier has a negative effect on intention to use air purifier, but is not related to intention to wear facemask. Neither exposure nor discussion is related to perceived threat. The effect of worry on intention to wear facemaskor intention to use air purifier is mediated by perceived threat. This proposed mediating mechanism is superior to the reverse mechanism (that worry mediates perceived threat). Implications of findings were discussed.

The Influence of COVID-19 Pandemic on the Health Seeking Behaviors of Adults Living With Chronic Conditions: A View Through the Health Belief Model

The COVID-19 pandemic resulted in disruption in every facet of life including health service delivery. This has threatened the attainment of global targets to improve health and wellbeing of all persons. In particular, for persons living with chronic diseases, who require consistent monitoring by health professionals and medication to enhance their health, understanding how the pandemic has disruption their access to health care delivery is critical for interventions aimed at improving health service delivery for all as well as preparedness for future pandemic. This study applied the constructs of the Health Belief Model, to explore the influences of the COVID-19 pandemic on the health seeking behaviors of persons living with chronic diseases. The design was exploratory descriptive. Semi-structured interviews were conducted to collect data among persons living with chronic diseases in the Cape Coast Metropolis of Ghana. Thematic analysis, both inductive and deductive, was conducted to unearth the findings. Awareness of increased susceptibility and risk of a more severe episode if they contracted COVID-19 as a result of the existing chronic diseases was identified. Lack of access to health professionals during the peak of the pandemic as well as the fear of contracting the virus while accessing their regular chronic disease clinic was the main barriers identified. Information in the media served as cues to action for adopting preventive health strategies. Behavior modifications; dietary and lifestyle, self-medication and adoption of COVID-19 related precautions were practiced. Susceptibility to contracting COVID-19 contributed to missed adherence to treatment appointment. The health belief model was a useful framework in exploring the health seeking behavior of the adults living with chronic conditions during the COVID-19 in this study setting. Intensifying targeted education for persons living with chronic diseases will contribute to the adoption of positive health seeking behaviors during future pandemic.

Health Literacy, Misinformation, Self-Perceived Risk and Fear, and Preventive Measures Related to COVID-19 in Spanish University Students

The "infodemic" is one of the main obstacles in the fight against the COVID-19 pandemic. In order to face it, health literacy (HL) is essential since it allows for knowledge about COVID-19 and the practice of preventive measures to be fostered. This is especially relevant in university students due to their idiosyncrasy. This study aims to evaluate the level of HL related to COVID-19 (HLC), risk perception, misinformation, and the attitudes and behaviors adopted to prevent the spread of coronavirus in Spanish university students. An online questionnaire was administered to 499 Spanish university students. The HLC index presented a mean of 33.89 out of 50; a total of 63.8% had an inadequate level of HLC. They practiced a mean of 7.54 out of 9 preventive behaviors, and the mean knowledge score was 10.40 out of 13. The HLC showed significantly different scores for the degree, the practice of preventive measures, and some sources of information. The level of HL correlates with the adoption of preventive measures. The higher the severity and perceived susceptibility, the more preventive measures are taken by the students. Therefore, there is a need to strengthen the HL skills of university students and address the dissemination of misinformation. Although caution should be taken when generalizing these results due to the limitations inherent within a cross-sectional study and the convenience sampling, our results can guide the establishment of health education strategies and policies for the management of the infodemic in pandemic situations, according to this target population.

Why context matters when changing the diet: A narrative review of placebo, nocebo, and psychosocial context effects and implications for outcome research and nutrition counselling

Placebo (PE) and nocebo effects (NE) have been subjects of systematic research in medicine and psychotherapy for many decades to distinguish between the (specific) pharmacological effect of medication and the (unspecific) effect of the context. Despite this significant research, the awareness, operationalisation, and reflection of the multiplicity of PE, NE, and psychosocial context effects (PSCE) is currently limited when researching outcomes of diet changes in studies without randomisation and placebo control. This neglection is critical as it could systematically influence outcomes by moderating and mediating them and thus reducing the validity and evidence base of these studies. Therefore, we performed a (non-systematic) narrative review (NR) on the following objectives: (1) present a concise overview about the relevance of PE, NE, and PSCE in medicine and nutrition research; (2) review the current state of research on reflecting context effects when studying diet changes; (3) provide useful theoretical foundations via consideration and integration of micro- and macro context effects; (4) operationalise as hypotheses the potential PE, NE, and PSCE which are specific for researching diet changes; and (5) derive their impact for future research as well as for nutrition counselling. The electronic search in this NR for objective (2) identified N = 5 publications and for objective (4) we found N = 61 articles retrieved in the first round of search, additional references were identified by a manual and snowball search among the cited references resulting finally in N = 37. This NR offers a synoptical basis to foster awareness and operationalisation of a variety of PE, NE, and PSCE. Interdisciplinary research teams should monitor these factors using, e.g., qualitative, mixed-method studies, process evaluation, item bank approaches, moderator and mediator analysis that might reveal substantially new insights, and outcomes of relevance to science and nutrition counselling. Nevertheless, the present NR has several limitations, especially as it is non-systematic, because it is a very heterogeneous field of research, in which the topic we are investigating is usually regarded as marginal and subordinate. Therefore, future research should conduct systematic reviews and particularly theory-based primary studies (experimental research) on hypotheses of PE, NE, and PSCE in outcome research in diet changes.

Diet and lifestyle factors associated with cognitive performance in college students

ObjectiveEngaging in a healthy diet and positive lifestyle behaviors have been shown to improve cognitive functioning in children and older adults, however, few have examined these factors in college-aged students. Participants: A diverse sample of 115 college students were recruited on two university campuses. Method: Completed computerized cognitive testing and an online survey about diet and lifestyle behaviors. Results: All analyses were conducted with Pearson's correlations. Higher fruit consumption was correlated with better visual memory scores. Higher seafood consumption was correlated with better learning performance. Increased fast food consumption was correlated with poorer executive functioning in resident students and poorer visual memory performance in commuter students. Increased fluid intake on testing day was correlated with better visual memory and better verbal memory performance. Conclusions: Behavioral changes such as increasing hydration, eating more fruit and fish, and eating less fast food may improve cognitive performance in college students.

Quasi-experimental design for using an interactive social media intervention program to improve truck drivers' health beliefs and eating behaviors

Background

Truck drivers have difficulties participating in health education programs delivered at a fixed time and place due to the mobility of their workplace. Interventions conducted via social media can overcome these limitations of time and place. This study aimed to investigate the effect of a nutrition education intervention program delivered via a social media platform on the healthy eating behaviors of truck drivers.

Methods

This study adopted a quasi-experimental design. A 12-week intervention program was conducted for a social-media group (n = 125) and a conventional-teaching group (n = 117) from February to May 2020. The social-media group participated in a social-media-based health intervention on the LINE application. The intervention involved the provision of online messages, online instant responses, a picture-based food log, an audio e-book, and a loyalty e-card. The conventional-teaching group participated in a healthy diet course and a hygiene education manual. The generalized estimation equation (GEE) was applied to evaluate the intervention effects on the outcome measures derived from the Health Belief Model.

Results

The results of the GEE showed the social-media-based intervention strategies significantly decreased perceived barriers of consuming a healthy diet (p =  < 0.001), increased willingness to follow cues of action (p = 0.036), improved the self-efficacy of healthy eating behaviors (p = 0.001), and increased the score of healthy eating behaviors (p < 0.001) compared with the conventional teaching strategies. For the social-media and conventional-teaching groups, no significant changes occurred in self-perceived health status, self-perceived susceptibility, or self-perceived severity after the intervention. More than 90% of the participants in the social-media group believed the social-media-based intervention strategies could help implement and maintain healthy eating behaviors.

Conclusions

The results indicate social-media-based intervention strategies can facilitate approaching a population without a fixed workplace, such as truck drivers. Health promoters and planners focusing on occupational health can consider developing social-media-based intervention strategies for improving truck drivers' health status.

Dietary Behaviours of University Students during the COVID-19 Pandemic. A Comparative Analysis of Nursing and Engineering Students

The university stage is a crucial stage that influences the decision-making process of students. At this stage, they acquire dietary habits that are guided by their likes, beauty ideals, biological influences, and economic factors. During the COVID-19 pandemic, universities closed and turned to online teaching, changing their life habits under the duress of confinement. The aim of the present work was to identify the dietary behaviours of nursing and engineering degree students at the University of Huelva during the period of confinement, in addition to identifying the factors influencing these habits. The methodological strategy employed was mixed in nature. In this sense, a cross-sectional descriptive study was first performed, followed by a phenomenological qualitative study that was descriptive in nature. Examination of outcomes revealed the presence of four lines of argument founded on the influence of context, life habits, emotional changes experienced during the COVID-19 pandemic, and the factors facilitating or limiting adaption to this period. Taking into account that confinement, restrictive measures, the absence of family, closeness and affection, and training influenced changes to feeding habits and approaches to consumption, universities could carry out interventions oriented in this line to favour healthy eating habits.

A Pilot Study on RTE Food Purchasing and Food-Related Behaviors of College Students in an Urbanized Area

Ready-to-eat (RTE) food is widely used, and younger age groups are increasingly purchasing these items. This study investigated college students' consumption of RTE foods and food-related behaviors such as dietary habits, lifestyle, eating out behaviors, and demographic characteristics. We used quantitative methods to gather data. A questionnaire was developed from previous studies and was self-administered to college students in Daejeon, Republic of Korea. Descriptive analysis, ANOVA, and Chi-square tests were conducted to investigate RTE food consumption behaviors and food-related lifestyle factors. A total of 285 data points was entered for analysis. This study found that BMI and gender significantly impacted dietary habits. Residence type and gender showed significant effects on dining out partners. Furthermore, results showed the time of snack consumption and RTE food were similar, suggesting that a snack was replacing college students' meals or that they might consider RTE food as a snack, or vice versa. A nutrition intervention program for college students should be implemented to encourage a healthy diet.

We Are What We Eat: Assessing the Use of a Documentary Film as an Educational Tool to Change Students’ Nutritional Attitudes and Behaviors

Background: Identifying effective educational strategies to change lifestyle behaviors related to eating habits is imperative for health professionals providing education related to disease management and prevention. The purpose of this study is to investigate the use of mass media as a tool for improving dietary habits. Methods: 151 Undergraduate students participated in a quasi-experimental control group design at a midsize liberal arts university. The treatment group watched the film Forks Over Knives and was assessed on their dietary habits, locus of control, and current stage of change before and after viewing the film. Results: Results showed differences to current stage of change in reducing animal-based food consumption in the treatment group but did not show significant changes in increasing plant-based food. Discussion: This study provides evidence that use of the documentary Forks Over Knives affects students’ intake of animal-based foods but is not an impactful enough tool to increase intake of plant-based foods. Translation to Health Practice: Professionals who utilize the film Forks Over Knives to encourage dietary changes should do so as part of a more structured, long-term behavior change intervention program. Additional research is needed to compare Forks Over Knives with other documentary films that encourage plant-based dietary habits.

Endocrine Disrupting Chemicals and Premenstrual Syndrome in Female College Students in East Asia: A Multi-Country Study

PURPOSE

This study aimed to explore the severity of premenstrual syndrome (PMS) and to examine associated factors with PMS among East Asian female college students with regard to endocrine-disrupting chemical (EDC).

PATIENTS AND METHODS

This study was a cross-sectional design. An online survey was completed by 520 female college students in Hong Kong and Korea. The structured questionnaire included items measuring knowledge of EDCs, actions taken and willingness to minimize exposure to EDCs, interest in EDCs, prior education on EDCs, life stress, severity of PMS, and general and health-related characteristics. Multiple logistic regressions were performed.

RESULTS

The prevalence of severe PMS among the participants was 54.6%. Factors associated with severe PMS included a self-reported heavy menstrual flow, underweight, obesity, interpersonal relationship stress, actions taken to minimize exposure to EDCs, and interest in EDCs.

CONCLUSION

This study provided the evidence of a negative association between severe PMS and the actions taken to minimize exposure to EDCs. To alleviate symptoms of PMS among young female adults, practical interventions, such as education to overcome barriers to preventing exposure to EDCs, are suggested.

Strategies to Promote Healthy Eating Among University Students: A Qualitative Study Using the Nominal Group Technique

Introduction

The years spent at university are critical in terms of altering people's dietary patterns. This study aimed to: (1) understand the main dietary changes that students experience after starting university; (2) determine the personal and objective factors that hinder healthy eating, and (3) define possible strategies to facilitate healthier diets among university students.

Methods

The nominal group technique (NGT) was used to elicit ideas from 39 students from the University of Parma, Italy. The sample comprised 16 freshmen and 23 non-freshmen. Participants prioritized and weighed their top five ideas regarding dietary changes, barriers to healthy eating, and possible strategies to maintain a healthy diet. A thematic analysis was conducted to compare the priorities across groups.

Results

Forty-three themes were elected as the most significant changes related to diet, 39 themes related to personal barriers, 43 themes related to objective barriers, and 55 themes related to strategies. A lack of time for cooking, low financial availability, consumption of unvaried food or junk food, and gaining knowledge about food were identified as the main changes. Personal barriers to eating healthy were intrinsic (i.e., lack of willpower, personal gluttony, and little effort in cooking preparation), poor dietary information, and a busy lifestyle. Market and financial factors (i.e., the high price of healthy products and low financial availability), as well as social factors (i.e., the negative influence of social networks, childhood food education, and origin/tradition), emerged as objective barriers. Possible strategies that could encourage students to adopt a healthy diet include varying the food products offered in university canteens, including organizing spaces where students who prepare meals from home can warm up and eat their food. Student discounts at supermarkets and information on nutrition and a healthy diet were also identified as important ways of supporting students.

Conclusion and Implication for Practice

In order to make students part of the solution, the NGT provided them with the opportunity to equally contribute their ideas and opinions about having a healthy diet in a university context. This could potentially lead to tailor-made solutions for policymakers, educators, and foodservice providers in promoting healthy eating habits.

Government Communication, Perceptions of COVID-19, and Vaccination Intention: A Multi-Group Comparison in China

Government communication has been playing an important role in mass vaccination to conduct the largest vaccination campaign of the world for COVID-19 and to counter vaccine hesitancy. This study employs the health belief model to examine the association between government communication and the COVID-19 vaccination intention. A survey of Chinese adults (N = 557) was conducted in March 2021, and partial least squares structural equation modeling was employed to estimate the multi-construct relationships. The findings indicate that government communication has both direct positive association with vaccination intention and indirect association with vaccination intention through the mediation of perceived severity, benefits, and barriers. Multi-group comparisons suggest that individuals from private sectors are more easily mobilized to receive COVID-19 vaccination by government communication than those from public sectors. Similarly, the correlation between government communication and the vaccination intention of individuals with a good health status was stronger than that of those with a poor health status. The theoretical and practical implications of these findings are further discussed.

Measuring university students' beliefs toward healthy snack selection

Objectives: Understanding university students' beliefs toward selecting healthy snacks is important in developing effective programs targeting healthy eating behaviors. The purpose of this research was to assess students' beliefs toward healthy snack selection and consumption. Participants: In November 2017, a convenience sample of 779 undergraduate students living on campus completed an online survey. Methods: A survey was developed to measure students' beliefs about eating healthy snacks. Paired t-tests were used to compare differences in beliefs and their importance. Independent t-tests were used to compare differences in belief responses by gender. Results: Students believed that healthy snacks were good for health and assisting with weight management. However, time management, motivation, preparation needs, and poor taste were reported as barriers to selection and consumption of healthy snacks. Conclusions: Increasing students' awareness of available food preparation facilities, developing food preparation skills, and motivation for consumption of healthy-good tasting snacks may increase healthier snacking.

Influencing nutritional habits of college students using a food pantry

Objective: Food insecurity in college students is associated with poor eating habits. The purpose of this project was to increase consumption of fruits and vegetables in college students using a campus food pantry. Participants: Twenty-nine college students completed the study. Methods: Participants viewed weekly food preparation videos demonstrating cost-effective recipes containing fruits and vegetables and a key take-away message. Participants were provided a recipe and food to cook at home based on the Cooking Matters Food Pantry Toolkit. A 24-h dietary recall was collected pre- and postintervention using the Automated Self-Administered 24-H Dietary Assessment. This descriptive comparative study used repeated measure ANOVA. Results: Females (n = 19) increased their fruit and vegetable consumption by 1.3 cups daily (p < .05) while males (n = 10) decreased fruit and vegetable consumption at the postintervention measurement. Conclusion: Increased consumption of fruits and vegetables in female college students using the food pantry was a modifiable behavior in this study.

Development of Food Literacy Assessment Tool Targeting Adults With Low Income

OBJECTIVE

Develop and test validity and reliability of the Food Literacy Assessment Tool (FLitT) in adults with low income.

DESIGN

Face validity was tested using cognitive interviews, content validity using expert review, and internal consistency reliability and test-retest reliability based on 2 administrations of the survey.

SETTING

Urban choice food pantry in Cincinnati, OH.

PARTICIPANTS

There were 10 and 98 adults with low income for the cognitive interview and survey, respectively VARIABLES MEASURED: Knowledge, self-efficacy, and behavior required to plan and manage, select, prepare, and eat in relation to food.

ANALYSIS

Cronbach α and Kuder-Richardson Formula 20 for internal consistency reliability and intraclass correlation coefficient (ICC) for test-retest reliability.

RESULTS

Cognitive interviews and expert feedback suggested modifications to improve the clarity of FLitT and offer more response options. Testing shows acceptable internal consistency in self-efficacy (Cronbach α = 0.92) and behavior (Cronbach α = 0.90) but not in knowledge (Kuder-Richardson Formula 20 = 0.51). The FLitT shows acceptable test-retest reliability for knowledge (ICC = 0.84), self-efficacy (ICC = 0.70), and behavior (ICC = 0.93).

CONCLUSIONS AND IMPLICATIONS

The FLitT was developed and tested for face and content validity and internal and test-retest reliability in adults with low income. Additional research is needed to conduct a second round of face validity and test construct validity using factor analysis with a larger size.

How Does the Family Influence Adolescent Eating Habits in Terms of Knowledge, Attitudes and Practices? A Global Systematic Review of Qualitative Studies

Promoting healthy eating habits can prevent adolescent obesity in which family may play a significant role. This review synthesized findings from qualitative studies to identify family barriers and facilitators of adolescent healthy eating in terms of knowledge, attitudes, and practices (KAP). A literature search of four databases was completed on 31 July 2020; qualitative studies that explored family factors of adolescent (aged 10 to 19 years) eating habits were included. A total of 48 studies were identified, with the majority being from North America and sampled from a single source. Ten themes on how family influences adolescent dietary KAP were found: Knowledge—(1) parental education, (2) parenting style, and (3) family illness experience; Attitudes—(4) family health, (5) cultivation of preference, and (6) family motivation; Practices—(7) home meals and food availability, (8) time and cost, (9) parenting style, and (10) parental practical knowledge and attitudes. This review highlights five parental characteristics underlying food parenting practices which affect adolescents’ KAP on healthy eating. Adolescents with working parents and who are living in low-income families are more vulnerable to unhealthy eating. There is a need to explore cultural-specific family influences on adolescents’ KAP, especially regarding attitudes and food choices in Asian families.

Telemedicine acceptance during the COVID-19 pandemic: User satisfaction and strategic healthcare marketing considerations

A lot remains unexplored regarding the antecedents and outcomes of telemedicine acceptance from health service marketing perspective. This study addresses this gap by integrating the Health Belief Model and the Unified Theory of Acceptance and Use of Technology model in the context of generation Y and Z's response to the COVID-19 pandemic. Data collected from 293 respondents were analyzed using structural equation modeling. The results confirm theoretical rigor of integrating two models examining the antecedents and user satisfaction as an outcome of telemedicine acceptance. The findings also suggest marketing strategies for implementing telemedicine during pandemic. Future research directions are highlighted.

Vitamin D Awareness and Intake in Collegiate Athletes

ABSTRACT

Leitch, BA, Wilson, PB, Ufholz, KE, Roemmich, JN, Orysiak, J, Walch, TJ, Short, SE, and Fitzgerald, JS. Vitamin D awareness and intake in collegiate athletes. J Strength Cond Res 35(10): 2742-2748, 2021-Poor vitamin D status is a risk factor for negative health and performance outcomes in athletes, but little is known about how athletes' awareness and beliefs about vitamin D affect their consumption of vitamin D. This observational study investigated awareness of vitamin D for health and performance among collegiate athletes and evaluated the association of vitamin D awareness with its dietary intake. Fifty-two female and 29 male Division I collegiate athletes completed an online vitamin D awareness and dietary intake questionnaire between November 1, 2015, and January 30, 2016. Median intake of vitamin D was 330 International Units (IU), which is below the recommended daily allowance (RDA) of 600 IU, but was greater in male athletes (693 IU) than female athletes (263 IU, p < 0.01). The RDA for vitamin D was met by 62% of men and 30% of women. Athletes responded that vitamin D "probably" or "definitely" will play a role in their health (88.9%) and athletic performance (71.6%). However, only 23.4 and 28.4% of athletes reported concern for their vitamin D levels or believed that they were at risk for deficiency, respectively. Results showed small-to-moderate, positive correlations (r = 0.28-0.495, p < 0.05) between aspects of vitamin D awareness and vitamin D intake, particularly with supplemental forms of vitamin D. Given the lack of awareness concerning risk of vitamin D deficiency, and the links between aspects of vitamin D awareness and vitamin D intake, nutritional education programs designed to increase vitamin D awareness in athletes may be an effective strategy to reduce deficiency.

Impacts of dietary self-monitoring via MyFitnessPal to undergraduate women: A qualitative study

The present study explored college women's perceptions of how dietary self-monitoring alters eating and body image-related cognitions and behaviors. The sample consisted of undergraduate women (N = 20), aged ≥ 18 (mean = 21.9 ± 6.6 years) from a cross-sectional qualitative study using semi-structured interviews conducted upon participants' completion of a randomized controlled trial testing the effects of dietary self-monitoring via the smartphone app, MyFitnessPal. Inductive content analysis was utilized to identify participants' perceptions of how engaging in dietary self-monitoring for one month impacted them. Participants' experiences dietary self-monitoring was highly variable, with some participants reporting increased negative feelings (n = 9), positive feelings (n = 7), or both (n = 2). Other notable findings included increases in weight and/or shape concerns (n = 10) and a number of changes in dietary intake and other behaviors. Participants indicated that dietary self-monitoring may be helpful when trying to lose weight but harmful if the behavior becomes obsessive or if the user has poor body image. Individual experiences with dietary self-monitoring varies widely, and while dietary self-monitoring may be a useful tool for some college women, use should be monitored to avoid possible harmful side effects.

Assessing COVID-19 preventive behaviours using the health belief model: A Sri Lankan study

Objective

The novel coronavirus (COVID-19) is turning out to be one of the most severe public health crises in recent history. Promoting preventive behaviour among the public is of paramount importance to effectively contain the disease. Hence, this research attempts to identify factors that affect preventive behaviour against COVID-19.

Methods

The Health Belief Model (HBM), which outlines how perceived susceptibility, severity, benefits, barriers, and health motivation affect individuals’ health behaviour, served as the theoretical basis of the study. As the outcome measure of the study was cues to action against COVID-19, a regression analysis was conducted to explore how the aforementioned HBM constructs influence the cues to action. The data were collected using an online survey with a total of 307 respondents.

Results

The results revealed that perceived benefits (0.395, p < 0.001), self-efficacy (0.405, p < 0.001), and general health motivation (0.313, p < 0.001) had significant positive impacts on the cues to action taken to prevent COVID-19, whereas perceived barriers (−0.097, p < 0.05) had a significant negative impact. The statistical analysis further revealed that the cues to action taken to prevent COVID-19 were not significantly influenced by perceived susceptibility and perceived severity.

Conclusion

The study reinstates the usability of the HBM in exploring health behaviour. Importantly, the study findings suggest that by informing the public of the benefits of prevention and general health motivation, and by encouraging self-efficacy and eliminating the barriers to prevention, preventive actions against COVID-19 can be effectively promoted.

Impact of education on health-beliefs in an emerging economy: Understanding urban vs. rural differences and the moderating effect of social capital

In this paper, we assert the critical influence of education on health-beliefs among women from India, an emerging economy. We further examine the urban vs. rural differences and the role of social capital in shaping health-beliefs of women. Using nationally representative data of eligible women from India, we find education to have a positive influence on health-beliefs. We find this effect to be higher in rural regions. Further, we find social capital to negatively moderate the effect of education. Our findings stress the importance of education, especially in rural regions.

Dietary and lifestyle habits among university students at different academic years

BACKGROUND/AIMS

College serves as a transitionary period into adulthood where students begin making independent dietary and lifestyle choices and begin forming possibly detrimental habits. Such habits may persist into adulthood and negatively affect their long-term health and risk of disease. This study aimed at exploring the dietary and lifestyle habits among the Hashemite University students at different academic years.

METHODS

A cross-sectional design was used to study dietary and lifestyle habits as well as the occurrence of obesity among a convenient sample of undergraduate students at the Hashemite University during the academic year 2015-2016. Five hundred and forty students (184 males: 356 females) were enrolled in this study. Bodyweight and height were measured and body mass index was calculated. Personal information, dietary habits and physical activity data were collected using constructed questionnaires.

RESULTS

Around 36% of the students were overweight and obese. The percentage of overweight among the freshmen was about 31% and 26.5% among the seniors. Additionally, 8.6% of freshmen and 16.3% of seniors were found to be obese. One-third (30.2%) of the study sample was hookah smokers, while 15.4% were cigarette smokers. The students showed similar physical activity levels in the four academic years. The majority of students at different academic levels consumed fruits 1-2 times/week and 5 times cereals, grains, and starchy vegetables/day.

CONCLUSION

Our results show that approximately one-third of students are overweight or obese, and practicing unhealthy dietary and lifestyle habits. This indicates a need to address this problem, possibly through implementing a nutrition and health education programs at the university in addition to improving the quality of food available on campus.

How Do Dieticians on Instagram Teach? The Potential of the Kirkpatrick Model in the Evaluation of the Effectiveness of Nutritional Education in Social Media

The growing popularity of health education on social media indicates the need for its appropriate evaluation. This paper aims to present the potential of the Kirkpatrick Model (KM) with New World Kirkpatrick Model (NWKM) additions to evaluate the nutritional education provided by dieticians via Instagram. Instagram profiles of ten dieticians providing nutritional education for their followers were analyzed in March and April 2021. The study sample included profiles of both macro- and micro-influencers. The analyzed quantitative data included Instagram Engagement Rate and the number of likes and comments per post. The qualitative analysis of the comments was performed following the theoretical framework provided by the KM and NWKM. Collected data showed followers' satisfaction, commitment, and relevance of the presented content, fulfilling the Level 1 of NWKM. Level 2 of NWKM was represented by 4 out of 5 dimensions (knowledge, attitude, confidence, commitment). No comments were found only for skills. Both Levels 3 (Behavior) and 4 (Results) of the KM were met. However, the use of the NWKM for them seems limited. The KM can be used to evaluate nutritional education on social media. The NWKM additions seem applicable mostly for Levels 1 and 2.

A model of digital health communication media use during the Covid-19 pandemic

Purpose

This research aims to develop and test a model of digital health communication media (DHCM) use for healthy food information – DHCM usage – during the Covid-19 pandemic. More specifically, this research investigated the simultaneous effects of perceived threat of Covid-19, e-health literacy, attitude toward DHCM usage, knowledge toward DHCM usage, facilitating conditions and information quality on the DHCM usage.

Design/methodology/approach

The empirical data were collected through a survey. The respondents of the survey are 192 DHCM users who lived in Tangerang Regency. Structural equation modelling (SEM) analysis was performed.

Findings

The DHCM usage during the Covid-19 pandemic is significantly affected by the attitude towards the DHCM usage and the facilitating conditions. However, the DHCM usage during the Covid-19 pandemic is not significantly affected by the perceived threat of Covid-19, e-health literacy, information quality and knowledge of the DHCM usage.

Research limitations/implications

This research was conducted only in Tangerang Regency and employed a purposive sampling technique. Future research should be conducted in other contexts to examine the stability of the research findings.

Practical implications

In order to improve DHCM usage for healthy food information, it is important for building a positive attitude towards DHCM usage and ensuring the availability of the facilitating conditions.

Originality/value

This paper is the first that develops and tests a model of DHCM usage for healthy food information during the Covid-19 pandemic.

Dietetic Students' Drivers and Barriers to Healthy Eating While Studying to Be a Healthcare Professional (a Pilot Study)

Background: For Dietetics students, starting university means developing the knowledge and skills required to be a healthcare practitioner. This pilot study aimed to explore the perceptions and views of the students on their drivers and barriers of healthy eating while studying Dietetics at university. Methods: A qualitative study was undertaken with a purposive sample of six final year Dietetic students at a UK university. Semi-structured in-depth interviews were used to elicit students’ experiences and perceptions of barriers to healthy eating. Interview data were analysed thematically. Results: Five themes emerged from the interview data including studying Dietetics, placement, influence of significant others, food security, and social and cultural aspects of the university life, with several sub-themes, and perspectives about the future beyond the university life. Conclusions: The findings suggest a potential need for Dietetics course providers to consider the range of barriers to healthy eating that students may encounter whilst studying and how these may undermine their ability to develop healthy eating practices and effective professional skills. Further research is required that explores the extent of barriers to healthy eating and examine whether these impinge upon effective practice.

The interplay of Western diet and binge drinking on the onset, progression, and outlook of liver disease

Non-alcoholic fatty liver disease and alcoholic liver disease, the two most prevalent liver diseases worldwide, share a common pathology but have largely been considered disparate diseases. Liver diseases are widely underestimated, but their prevalence is increasing worldwide. The Western diet (high-fat, high-sugar) and binge drinking (rapid consumption of alcohol in a short period of time) are two highly prevalent features of standard life in the United States, and both are linked to the development and progression of liver disease. Yet, few studies have been conducted to elucidate their potential interactions. Data shows binge drinking is on the rise in several age groups, and poor dietary trends continue to be prevalent. This review serves to summarize the sparse findings on the hepatic consequences of the combination of binge drinking and consuming a Western diet, while also drawing conclusions on potential future impacts. The data suggest the potential for a looming liver disease epidemic, indicating that more research on its progression as well as its prevention is needed on this critical topic.

Tramadol Biological Effects: 4: Effective Therapeutic Efficacy of Lagenaria siceraria Preparation (Gamal & Aref1) and Melatonin on Cell Biological, Histochemical, and Histopathological Changes in the Kidney of Tramadol-Induced Male Mice

Tramadol is used worldwide and is listed in many medical guidelines to treat both acute and chronic pains. There is a growing evidence of abuse of tramadol in some African and West Asian countries. Tramadol has some side effects. The present study designed to follow up the treatment of the cellular responses which might be induced in the kidney of tramadol mice. Treated mice received daily injection of tramadol dose (125 μg/100 g b.wt) for 20 and 40 days. Other mice received tramadol for 40 days and then were divided into three groups: the first received distilled water, the second received Lagenaria siceraria, and the third received melatonin daily for 40 days. Both the daily injection of tramadol for 20 and 40 days resulted in radical, extensive, and severe alterations in the normal histological architecture of the kidney. Treatment with Lagenaria siceraria or melatonin after tramadol administration for a long-term, markedly changed the collagen content and other chemical components, that may reach nearly normal levels. Such findings propose that although tramadol has many cytological and histopathological side effects on the kidneys of male mice, the treatments via Lagenaria siceraria and melatonin have effective therapeutic impacts on the tramadol side effects.

Predictors of Seat-Belt Use among Bus Passengers in Ghana: An Application of the Theory of Planned Behaviour and Health Belief Model

BACKGROUND

Seat-belt use is effective in preventing traffic fatalities and injuries yet its use is not universal. This study sought to determine the predictors of self-reported seat-belt use among bus passengers in Ghana based on the theory of planned behaviour and health belief model.

METHODS

A quantitative cross-sectional study design with 633 randomly selected intercity bus passengers was conducted using a structured questionnaire in Kumasi, Ghana. The resulting data were analysed using SPSS version 23.0. Ordinal regression was employed to determine the predictors of self-reported seat-belt use.

RESULTS

Majority of the respondents were male (61.5%) with a mean age of 32.2 (SD = 11.6). A third (33.0%) reported that they always wear their seat-belt as bus passengers. The results indicated that intention (OR = 1.49, 95% CI = 1.21-1.84, p = 0.001), subjective norm (OR = 1.57, 95% CI = 1.15-2.13, p = 0.004) and perceived behavioural control (OR = 1.53; 95% CI = 1.21-1.92, p = 0.001) variables from the theory of planned behaviour were significant independent predictors of seat-belt use. Among the health belief model variables, perceived severity (OR = 1.57, 95% CI = 1.15-2.16, p = 0.005) and perceived barriers (OR = 0.52, 95% CI = 0.39-0.67, p = 0.001) were the only significant independent predictors of self-reported seat-belt use.

CONCLUSION

The findings suggest that intention, subjective norm, perceived behavioural control, perceived severity and perceived barriers play an important role in determining bus passengers' seat-belt use behaviour. Road safety programmes to increase seat-belt use will gain from giving serious attention to these factors in the design and implementation of such programmes.

A Social Marketing Intervention to Improve Treatment Adherence in Patients with Type 1 Diabetes

This research explores if a social marketing intervention model based on social representations theory and the health belief model can generate changes regarding treatment adherence and improve patient self-efficacy. As a pilot, a test-retest field quasi-experiment was designed to evaluate the intervention model with type 1 diabetes (T1DM) patients of families with 8- to 17-year-old children. The intervention model was designed to clarify misconceptions, increase awareness of the benefits of following doctors' treatments and improve patients' self-efficacy. In-depth interviews were carried out to gain a richer understanding of the intervention's effect. The pilot intervention generated a favourable change in shared misconceptions, individual health beliefs, glycaemic control and declared treatment adherence. This paper contributes to the social marketing literature and public health by providing early support for the theoretical assumptions regarding the role of shared misconceptions in physiological and behavioural outcomes for patients with T1DM. Contrary to previous studies, instead of only focusing on individual beliefs, this study incorporates shared beliefs between patients and caregivers, generating more comprehensive behavioural change.
