Comparative Study On ‘Dietary Education’ In Japan And Korea: From The Latest Nutritional Knowledge Perspective

According to the Japan’s National Health and Nutrition Survey, trends in the intake of vegetables and fruits (1999-2018), which are considered effective in preventing lifestyle-related diseases, are far below the target value; In the under-50 age group, less than 30% achieved the target vegetable intake of 350g, and less than 15% achieved the target fruit intake of 200g 53. Against such background, it has become a challenge to nurture children's ‘self-management ability’ that leads to spontaneous and healthy dietary habits 16. Until now, almost all research on ‘Dietary education’ has been conducted in the field of nutrition, focusing on accumulating nutritional knowledge by explaining each nutritional component and its function. However, it is difficult to nurture spontaneous and healthy dietary habits simply through repeated nutrition-based education. It can be said that the pedagogical approach of this paper has made it possible to pursue from a broader perspective that influences food choices. Research on ‘nutrition transition’ points out “worldwide obesity dynamics and their determinants” based on “a shift in the broader patterns of dietary habits (Western-style diet) and corresponding nutrition-related diseases” 42. Nutrition transition research 50, 40 has a broad and holistic perspective on food and health, making it easy to understand nutrition. The purpose of this paper is to pursue how to nurture the ‘self-management ability’ for spontaneous and healthy dietary habits, based on these latest nutritional knowledges. Because nutrition transition is a global phenomenon, the author choses to use broader methods of international comparative research. Comparisons lead to discoveries and value creation. This can be said to have the greatest significance in comparative research.

Association of healthy lifestyle score with control of hypertension among treated and untreated hypertensive patients: a large cross-sectional study.

Hypertension stands as the leading single contributor to the worldwide burden of mortality and disability. Limited evidence exists regarding the association between the combined healthy lifestyle score (HLS) and hypertension control in both treated and untreated hypertensive individuals. Therefore, we aimed to investigate the association between HLS and hypertension control among adults with treated and untreated hypertension. This cross-sectional study, including 311,994 hypertension patients, was conducted in Guangzhou using data from the National Basic Public Health Services Projects in China. The HLS was defined based on five low-risk lifestyle factors: healthy dietary habits, active physical activity, normal body mass index, never smoking, and no alcohol consumption. Controlled blood pressure was defined as systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg. A multivariable logistic regression model was used to assess the association between HLS and hypertension control after adjusting for various confounders. The HLS demonstrated an inverse association with hypertension control among hypertensive patients. In comparison to the low HLS group (scored 0-2), the adjusted odds ratios (95% confidence intervals) for hypertension were 0.76 (0.74, 0.78), 0.59 (0.57, 0.60), and 0.48 (0.46, 0.49) for the HLS groups scoring 3, 4, and 5, respectively (Ptrend < 0.001). Notably, an interaction was observed between HLS and antihypertensive medication in relation to hypertension control (Pinteraction < 0.001). When comparing the highest HLS (scored 5) with the lowest HLS (scored 0-2), adjusted odds ratios (95% confidence intervals) were 0.50 (0.48, 0.52, Ptrend < 0.001) among individuals who self-reported using antihypertensive medication and 0.41 (0.38, 0.44, Ptrend < 0.001) among those not using such medication. Hypertensive patients adhering to a healthy lifestyle without medication exhibited better blood pressure management than those using medication while following a healthy lifestyle. HLS was associated with a reduced risk of uncontrolled blood pressure.

Recommendations: Raise the level of knowledge and practice for prevention, learn pregnant women healthy dietary habit and encourage pregnant women to early registration in primary health care center.

Mapping the potential of meal kits to influence parental food literacy: an application of behaviour change frameworks

Cooking at home and eating together provide opportunities to improve family nutrition and promote healthy dietary habits. Commercial meal kit subscription services (MKSSs) (e.g. HelloFresh™, Marley Spoon™, EveryPlate™) may support parents to overcome obstacles to family meal provisioning and facilitate food literacy development. A gap exists in our understanding of how and why meal kits may elicit behaviour change, and opportunities to increase their behaviour change capability. This study aimed to examine the theoretical potential of Australian MKSSs to promote parental food literacy using the Behaviour Change Wheel (BCW)(1) and associated Theoretical Domains Framework (TDF)(1) and Behaviour Change Technique Taxonomy v1 (BCTTv1)(2). A one-week subscription was purchased for all Australian-based MKSSs (n = 9) and key meal kit components (subscription and meal planning features, meal kit delivery and website content) were coded using the retrospective application of these behaviour change frameworks. Parental food literacy-related behaviours were informed by a Food Literacy framework(3). Identified BCTs were mapped to the TDF using the Theory and Techniques Tool to identify theoretical mechanisms of action. The key meal kit components identified mapped to eight of the nine BCW intervention functions. These components primarily served the functions of enablement and environmental restructuring to support cooking at home. Thirty-five of the 93 possible BCTs were identified across the nine MKSSs reviewed, ranging from 19 to 29 BCTs per company, and linked to 13 of the 14 TDF domains. The most frequently identified mechanisms of action (TDF) targeted changes in motivation (n = 27) and capability (n = 19) to influence parental food literacy. Australian-based MKSSs incorporate a wide range of BCTs that target mechanisms of action associated with food literacy-related behaviours. These findings provide a strong theoretical evidence-base for the potential of commercial MKSSs to enhance parental food literacy. However, the extent to which these services may influence behaviour change or impact family food intakes is currently unknown. Therefore further research is required to evaluate the healthfulness and effectiveness of MKSSs.

Victorian (Australian) parents are receptive to the idea of a primary school-provided lunch program: A mixed-method survey

School-provided lunch programs offer numerous benefits to primary school students including improved school attendance and performance, reduced undernutrition, reduced food insecurity, the opportunity to learn healthy eating, and the development of healthy dietary habits(1–3). Australia does not have an ongoing national school-provided lunch program that provides food for all students. To successfully implement a school-provided lunch program in Australian primary schools, it is essential to obtain the opinions of all key stakeholders, including parents. This study aimed to examine Victorian primary school parents’ opinions about a potential school-provided lunch program. An online cross-sectional survey with open- and closed-ended questions was conducted in Victoria, Australia, in 2022. Descriptive statistics and chi-square analyses were performed using SPSS software; thematic analysis was carried out using NVivo. Three hundred and fifty-nine parents responded to the survey. Fifty-seven percent of respondents said they would allow their child to participate in a school-provided lunch program, 34% were unsure and only 9% said they would not. The opportunity for hot-cooked lunches at school and the perceived convenience for parents were the top two reasons for favouring such a program. Fifty-eight percent were in favour of hybrid-type funding from both the government and parents, while 30% were in favour of being fully funded by the government. The most preferred amount to pay per meal was AUD5-6 (43%), followed by AUD3-4 (25%). When respondents were asked to rate the importance of six options in school-provided lunches (vegetarian, nut-free, dairy-free, gluten-free, egg-free, and vegan options), almost one-third of them selected having ‘vegetarian’ options as important or very important, whilst one-fifth selected ‘nut-free’, ‘dairy-free’, and ‘gluten-free’ options as important or very important. There were no associations between the parents’ or children’s socio-demographic characteristics and the likeliness of letting their children use school-provided lunches, funding preference, the amount willing to pay for school lunches, and the importance of different options. Respondents’ written responses revealed that they expected school-provided lunches to be healthy and made from whole food and cater to the special dietary and cultural needs of their children. Their other expectations included food being tasty and offered in a child-friendly way, having a variety of food offered, and having backup options if the children would/ could not eat those meals. They also expected enough time to be provided for eating lunches so children could eat and enjoy the meals. The findings of this study suggest that Victorian primary school parents are open to the idea of a school-provided lunch program, but they do have several expectations regarding the menu and time for eating. Program planners could use the findings of this study to create a school lunch program that aligns with the parents’ expectations and preferences.

Implementing eHealth-based behaviour change support within a nutrition intervention trial improves adherence to study-related behaviours in healthy young adults

Nutrition intervention trials play a key role in informing clinical and dietary guidelines. Within these trials, we need participants to change their behaviours; however, researchers seldom systematically consider how to support participants with these changes, contributing to poor adherence. Here we evaluate how using a behaviour change framework to develop support within a dietary intervention impacts young adults’ adherence to required trial behaviours. In the Protein Diet Satisfaction (PREDITION) trial, 80 young adults were randomised to a flexitarian or vegetarian diet for 10-weeks to investigate the psychological and cardiometabolic effects of moderate lean red meat consumption as part of a balanced diet(1). To understand these outcomes, it was key that participants within the trial (i) ate a healthy, basal vegetarian diet (excluding meat, poultry, and fish not provided by research team) and (ii) reported their dietary intake daily on a smartphone application (required to evaluate intervention compliance). To enhance adherence to these behaviours the Nine Principles framework was used to develop behaviour change support (BCS)(2). Key components of the BCS included access to a dietitian-led Facebook group, text reminders, and food delivery. Effectiveness was measured using the following analyses of the 78 participants who completed the study: pre-post change in targeted dietary habits over time using a subscore of the Healthy Diet Habits Index, adherence score to reporting over 10-weeks, Facebook group engagement, and impact evaluation. Analysis included linear imputation modelling, t-tests, and chi-square analysis. The total Healthy Diet Habits Index subscore out of 16 significantly increased from baseline to week 10 (10.6 ± 2.6 to 11.2 ± 2.6, p = 0.011), demonstrating maintenance of a healthy diet. Overall adherence to reporting was high across the 10 weeks, with the total population mean reporting score 90.4 ± 14.6 out of a possible 100. This strengthens study validity, allowing us to confidently report if participants complied with study requirements of consuming the intervention protein (red meat or plant-based meat alternatives) on top of a basal vegetarian diet. Although relatively low active Facebook engagement was observed (on average &lt;1 ‘react’ per post), most participants agreed the text messages and Facebook groups supported them to adhere to recording (63%) and eating healthily (60%), respectively. This is the first study to provide an example of how a framework can be used to systematically develop, implement, and assess BCS within a nutrition trial. This appears to be a promising way to enhance adherence to study-related behaviours, including the burdensome task of reporting dietary intake. We believe this has great potential to improve research validity and decrease resource waste, not only for the PREDITION trial but in future dietary intervention trials.

Risk Factors of Early Age Colorectal Cancer among Patients Attending at National Institute of Cancer Research &amp; Hospital

Background: Colorectal cancer (CRC) poses a significant public health burden worldwide, with a notable trend of increasing incidence among individuals aged 20 to 50 years. Understanding the risk factors associated with early-onset CRC is crucial for developing targeted prevention and intervention strategies, particularly in limited-resource settings. Objective: This study aimed to identify and analyze the risk factors contributing to the development of early-onset CRC in a population from a limited-resource country. Method: A comparative study was conducted among 178 CRC patients admitted to the National Institute of Cancer Research &amp; Hospital (NICRH), Dhaka. Patients were divided into two groups: Group-A (age 20-50 years) and Group-B (age &gt;50 years). Demographic and clinical data were collected, and statistical analyses were performed to determine associations between various risk factors and early-onset CRC. Results: The mean age of Group-A subjects was 43.6±7.1 years, significantly younger than Group-B subjects (59.2±9.3 years). Male patients constituted 69.1% of the cohort, with a statistically significant male-to-female ratio of 2.2:1. Higher BMI (≥25) was strongly associated with early-onset CRC (p&lt;0.01). Occupations such as business and middle socioeconomic status were significantly linked to early-onset CRC. Regular exercise (&gt;30 minutes daily) demonstrated a protective effect against CRC development. Consumption of red meat and fast food was associated with a higher risk of CRC, while regular consumption of vegetables was protective. Familial adenomatous polyposis (FAP) presence was significantly associated with early-onset CRC. Conclusions: Male sex, high BMI, specific occupations, dietary factors, and presence of FAP emerged as key risk factors for early-onset CRC. Encouraging regular exercise and promoting healthy dietary habits, particularly reducing red meat and fast-food intake, are crucial in mitigating the risk of early-onset CRC in similar populations.

Implementing Aging in Place in Hong Kong: Meeting the Needs and Aspirations of Older Adults and Their Caregivers Living in Private Housing.

A policy of aging in place should be accompanied by physical and social environments that support healthy aging. This article describes how a property development company in Hong Kong sought to elicit the views of older people and their caregivers towards elderly services through a market research company, using questionnaire surveys followed by focus groups. Over 80% of all participants rated healthy dietary habits and exercise, maintaining mental and spiritual health, and maintaining a generally healthy lifestyle as important. Current health concerns include long waiting times for care at public hospitals, lack of carer should dependency occur, and lack of information about what services are available in the community. Interests in services in their neighbourhood include medical care (82%), healthy lifestyle activities (66%), and home care support (55%). There was considerable interest in the provision of services that improve brain and physical function, as well as general health checks. Carers were willing to pay more for services compared with older adults themselves. The findings inform the development of pilot models of aging in place as a sustainable financial model.

Sex differences in waist circumference obesity and eating speed: a cross-sectional study of Japanese people with normal body mass index.

Fast eating has been positively associated with visceral fat accumulation in normal-weight individuals according to body mass index (BMI). However, previous studies have not examined energy and nutrients, or adjusted for food intake. We examined the relationship between eating speed and visceral fat accumulation, using waist circumference as an index, in middle-aged participants who were considered to be of standard weight according to BMI, with nutrient intake added as an adjustment factor. We included 6,548 Japanese participants (3,875 men and 2,673 women) aged 40-74 years with BMI 18.5-25.0 kg/m2 who were enrolled in the Yamagata Cohort Study. Participants were divided into "fast," "normal," and "slow" eaters according to self-reported eating speed. Nutrient and food intake were evaluated using a food frequency questionnaire, and the difference in intake by eating speed and sex was compared. Logistic regression analysis was used to examine the relationship between waist circumference obesity (men ≥85 cm, women ≥90 cm, according to Japanese criteria) and eating speed, adjusted for nutrient intake and other lifestyle habits. In men, slow eaters had greater intakes of dietary protein, fat, polyunsaturated fatty acids (PUFA), omega-3 PUFA, total dietary fiber, soluble dietary fiber, insoluble dietary fiber, soybean products, fish, green and yellow vegetables, other vegetables, mushrooms, and seaweed in comparison with normal-speed eaters. In men, waist circumference obesity was significantly lower among slow eaters than in the group with normal eating speed. In women, waist circumference obesity was not significantly associated with eating speed and was not also associated with nutrient/food consumption except omega-6 PUFA. Eating slowly was associated with healthy dietary habits. Our results could help prevent waist circumference obesity in men with a BMI between 18.5 and 25.0 kg/m2. However, similar findings were not observed in women, suggesting a sex difference.

The association between unhealthy dietary behaviors and participation in the Supplemental Nutrition Assistance Program (SNAP): No evidence in support of the self-selection hypothesis

Supplemental Nutrition Assistance Program (SNAP) participants tend to have unhealthier dietary consumption compared to eligible non-participants. It has been suggested, though never empirically tested, that individuals who enroll in SNAP may have unhealthy diets prior to program participation. Using a longitudinal cohort study design, we examined the association between low-income adults' SNAP participation status and prior dietary behaviors to test the argument that individuals with unhealthier dietary consumption self-select into SNAP. A sample of households from predominantly lower-income cities were surveyed at baseline (T1) and 2–4 years later (T2). The main analyses were restricted to adults who did not participate in SNAP at T1 and with household income <200% of the federal poverty line (n = 170) at both T1 and T2. Participants were grouped into two categories, based on their SNAP participation at T2; (a) Non-participants (n = 132): no SNAP participation at T1 or T2, and (b) T2 SNAP participants (n = 38): SNAP participation at T2 but not T1. Daily consumption frequency of whole fruits, fruit juice, vegetables, sugar-sweetened beverages (SSBs), and energy dense snacks were measured through self-reports. To observe dietary differences between the two groups prior to SNAP participation, T1 behaviors were compared. There were no significant differences in dietary behaviors at T1 (prior to SNAP participation) between non-participants and T2 participants, providing no evidence of self-selection of individuals with unhealthier dietary consumption into SNAP among our study sample. Improvements in SNAP participants’ diets may benefit from focusing on policy changes that encourage healthy dietary habits during participation in the program.

Dietary Habits and Depression in Community-Dwelling Chinese Older Adults: Cross-Sectional Analysis of the Moderating Role of Physical Exercise.

Healthy diets and physical exercise, two modifiable lifestyle factors, are protective against depression in older adults. This study aimed to investigate whether physical exercise may influence the associations of dietary habits with depression in Chinese community-dwelling older adults. In the 2018 wave of the Chinese Longitudinal Healthy Longevity Survey, 12,708 community-dwelling older adults aged ≥65 years were included for analyses. Older adults' dietary habits (including daily intake of food components such as fruits, vegetables, animal oil, and so on) and physical exercise were assessed. Depression was evaluated via the 10 item Center for Epidemiologic Studies Depression (CES-D-10) scale. The influences of physical exercise on the associations of dietary habits with depression were estimated using logistic regression models adjusted for confounders. Older adults who took physical exercise had a significantly decreased probability of depression (adjusted OR = 0.73, p < 0.001). As for dietary habits, the intake of fruits, vegetables, eggs, nut products, mushrooms or algae, and vitamins were inversely associated with the prevalence of depression (adjusted ORs = 0.61-0.81; p-values: from <0.001 to 0.025), while animal oil was positively associated with it (adjusted OR = 1.52, p < 0.001). When stratified by physical exercise, older adults who ate fruits or vegetables had consistent decreased risk of depression, no matter whether they took physical exercise or not (adjusted ORs = 0.52-0.70), while the intake of eggs, nut products, and vitamins were inversely associated, and animal oil was consistently positively associated with depression only in older adults who did not take physical exercise (adjusted ORs = 0.79, 0.68, 0.63, and 1.67, respectively). Physical exercise may conceal the potential protective effects of some healthy dietary habits in terms of depression and counteract the detrimental effects of the unhealthy habits. Some dietary habits may be considered as alternative protective measures for depression in community-dwelling older adults when physical exercise cannot be performed.

Sedentary Behaviors and Eating Habits in Active and Inactive Individuals: A Cross-Sectional Study in a Population from Southern Italy.

The aim of this study was to analyze sedentary behaviors and dietary habits assumed by individuals regularly practicing exercise in a gym, sports athletes and inactive individuals. The Sedentary Behavior Questionnaire and the Healthy Dietary Habits Index were administered online to evaluate the time spent in sedentary activities during the week and the habits of food consumption among adult individuals from the Campania region, in the south of Italy. Of the 411 participants, 25% were inactive, 34% were gym practitioners and 41% practiced different sport disciplines. Significant differences were found for sedentary habits adopted during the week and diets between athletes and inactive participants. However, no significant differences were observed for sedentary activities on the weekend and some sedentary behaviors such as video gaming or working/studying during the week. With regard to diet, athletes showed healthier food choices, such as fruit and vegetable consumption. The findings of this study underline the need for enhancing the awareness of the local population regarding the detrimental effects of unhealthy dietary behaviors and sedentary time, especially but not exclusively among inactive individuals.

Public awareness of war on diabetes campaign and its association with behavioural outcomes.

The War on Diabetes campaign was launched in 2016, encouraging Singapore residents to engage in regular exercise, adopt healthy dietary habits and screen for early detection of diabetes. This study aims to examine campaign awareness and its associations with sedentary behaviour, dietary habits and identifying diabetes. Data were obtained from the nationwide Knowledge, Attitudes and Practices study on diabetes in Singapore. A total of 2895 participants responded to a single question assessing campaign awareness. The Dietary Approaches to Stop Hypertension (DASH) diet screener assessed dietary habits, and the Global Physical Activity Questionnaire (GPAQ) measured sedentary behaviour. Recognition of diabetes was established using a vignette depicting a person with diabetes mellitus. Logistic and linear regression models were used to measure the associations. Most participants were 18- to 34-years old (29.9%) and females (51.6%). About 57.4% identified the campaign. Campaign awareness exhibited positive associations with identifying diabetes based on the vignette [odds ratio (OR): 1.5; 95% confidence interval (CI): 1.1-2.2; P = 0.022], lower odds of sedentary behaviour ≥7 h/day (OR: 0.7; CI: 0.5-0.9; P = 0.018) and higher DASH scores (β = 1.3; P < 0.001). The study recognized early significant associations between the behavioural outcomes and the campaign, emphasizing the need for ongoing campaign sustainability and evaluation of its long-term impact on population health.

Advancements in Sustainable Plant-Based Alternatives: Exploring Proteins, Fats, and Manufacturing Challenges in Alternative Meat Production.

The rise in plant-based food consumption is propelled by concerns for sustainability, personal beliefs, and a focus on healthy dietary habits. This trend, particularly in alternative meat, has attracted attention from specialized brands and eco-friendly food companies, leading to increased interest in plant-based alternatives. The dominant plant-based proteins, derived mainly from legumes, include soy protein isolates, which significantly impact sensory factors. In the realm of plant-based fats, substitutes are categorized into fat substitutes based on fats and fat mimetics based on proteins and carbohydrates. The production of these fats, utilizing gums, emulsions, gels, and additives, explores characteristics influencing the appearance, texture, flavor, and storage stability of final plant-based products. Analysis of plant-based proteins and fats in hamburger patties provides insights into manufacturing methods and raw materials used by leading alternative meat companies. However, challenges persist, such as replicating meat's marbling characteristic and addressing safety considerations in terms of potential allergy induction and nutritional supplementation. To enhance functionality and develop customized plant-based foods, it is essential to explore optimal combinations of various raw materials and develop new plant-based proteins and fat separation.

Advancing nutrition risk assessment in middle-aged and older individuals with diverse food cultures: A data-driven personalized approach to predict incident hypertension, diabetes and mortality.

Personalized nutrition risk assessment is crucial in addressing the association between healthy dietary habits across the life course and the development of disease, functional capacity, and healthy aging, as specific dietary pattern recommendations may not be suitable for diverse food cultures. To develop a data-driven, personalized nutrition risk assessment algorithm linked to incident hypertension, diabetes, and all-cause mortality utilizing the food frequency questionnaire among middle-aged and older individuals. A retrospective, population-based cohort study conducted between 1999 and 2015 utilized the nationally representative Taiwan Longitudinal Study on Aging (TLSA) survey to examine personalized dietary risk clusters and their associations with health outcomes. Latent class analysis was performed to derive the dietary diversity clusters among community-dwelling middle-aged and older individuals. Outcomes were defined as new-onset hypertension, diabetes mellitus and all-cause mortality at 4-, 8-, 12- and 16-year follow-ups. Data from 1,811 participants (58.14% males, 43.90% aged 50-64 years) showed that around one-third of participants reported being illiterate, 21.98% widowed, and 51.46% engaging in regular physical exercise. Four dietary diversity clusters were identified: "least diverse", "fish and meat", "dairy, fruit, and vegetable", and "most diverse". The "most diverse" cluster was characterized by a high consumption of protein-rich foods, while the "dairy, fruit, and vegetable" cluster had the highest consumption of dairy products and beans/legumes. The "least diverse" cluster had the lowest intake of protein-rich foods, and dark-colored vegetables and fruits. The "most diverse" cluster had a significantly lower risk of hypertension development at the 4-year (aOR 0.58; p < 0.02) and 8-year (aOR 0.57; p < 0.01) follow-up and diabetes at the 4-year (aOR 0.44; p < 0.03) follow-up. Participants in the "most diverse" clusters exhibited lower risks of 8-year, 12-year, and 16-year mortality than those in the "least diverse" cluster (aOR 0.67, p < 0.05; 0.67, p < 0.03; and 0.50, p < 0.01, respectively). The personalized nutrition risk assessment algorithm from the food frequency questionnaire can effectively stratify personal health risks among diverse middle-aged and older individuals, making it a valuable tool in lifestyle modification and intervention studies.

Assessment of lifestyle changes related to quarantine among Saudi population during the early COVID-19 pandemic: pre- and post-analysis

BackgroundThe escalating emergence of the COVID-19 pandemic interrupted human life due to the ever-increasing morbidity, containment measures, and the associated emotional distress. This study examined the influence of COVID-19-related measures on the lifestyle behaviors of adults living in the Kingdom of Saudi Arabia (KSA).MethodsThe study recruited 638 participants through convenience sampling in Jeddah and Taif cities, Saudi Arabia. Demographic characteristics and COVID-19-related information were collected through an anonymous self-reported electronic questionnaire. Lifestyle behaviors were assessed before and during the quarantine using the Healthy Dietary Habits Index (HDHI)-A and the International Physical Activity Questionnaire (IPAQ-SF).ResultsThe study revealed significant changes in the dietary pattern: a reduction in fish intake and increased consumption of French fries and candies. Vegetables and fruit intake increased significantly. Sedentary time > 6 h per day increased from 36.7% pre to 60.8% during the pandemic. Healthy dietary index score and physical activity MET-minutes/week values were respectively 3.5% and 37.9% significantly higher before compared to the full quarantine period.ConclusionThe pandemic detrimentally influenced eating habits and physical activity levels that led to weight gain, and hence higher vulnerability to COVID-19 infection and negative outcomes. This analysis provides public health agencies with data to tailor nutrition interventions that mitigate the observed adverse lifestyle behaviors.

Exploring factors influencing farmers’ health self-assessment in China based on the LASSO method

As the main force and practice subject of rural revitalisation, farmers' health is intricately linked to agricultural production and the rural economy. This study utilizes open data from the 2015 China Nutrition and Health Survey and employs the Least Absolute Shrinkage and Selection Operator (LASSO) method to explore the factors influencing farmers' self-assessment of health. The findings reveal that education level, proactive nutrition knowledge seeking, healthy dietary preferences and habits, and the use of clean cooking fuel positively impact farmers' health self-assessment. Conversely, age, history of illness or injury, and participation in medical insurance negatively affect their self-assessment. Furthermore, factors influencing farmers' health self-assessment exhibit heterogeneity across regions. Our findings suggest that promoting health education, disseminating nutritional dietary knowledge, and enhancing rural household infrastructure play an important role in improving farmers' self-evaluation of health. Therefore, policymakers should design more targeted health interventions and infrastructure improvement plans based on farmers' self-assessment of health and the level of regional economic development.

Determinants of Food Ordering Applications Adoption among Saudi Consumers and their Effect on Dietary Habits

Objectives: This study aims to contribute knowledge toward understanding the effect of food ordering applications (FOA) on consumer behavior regarding food consumption and dietary habits of the Saudi population. Methods: This cross-sectional study tested the Theory of Planned Behavior (TPB) within the domain of FOA with adult users (N=834) using an online questionnaire. Results: Structural equation modeling (SEM) analysis revealed that among the TPB constructs, attitude had the largest positive and direct effect on participants' intention in FOA's adoption followed by subjective norms and perceived behavioral control variables. Overall, the 3 TBP constructs accounted for 49% of the variance in intention, whereas intention accounted for 33% of the variance in behavior. Conclusion: Our results suggest that TPB constructs represent an important aspect in studying consumer behavior regarding FOA. Moreover, the use of FOA may influence healthy dietary habits.

Magnitude and Predictors of Dietary Diversity among HIV-Infected Adults on Antiretroviral Therapy: The Case of North-Western, Ghana.

Though people living with HIV/AIDS require a good combination of antiretroviral therapy and healthy dietary habits for a quality life and positive medical outcomes, little is, however, known regarding the dietary practices of HIV-positive patients who receive antiretroviral therapy (ART) in the Lawra Municipality. This study assessed the magnitude and factors associated with dietary diversity among HIV-positive patients on antiretroviral therapy (ART). This study was a facility-based cross-sectional study of 269 study participants recruited using a systematic random sampling technique. Bivariate and multivariable logistic regression analyses were performed to identify factors associated with their dietary diversity. This study shows that only 36 (13.4%) of the sample consumed a diversified diet with a mean dietary diversity score of 3.7 ± 0.99. Starchy staple foods (96.7%) and flesh food (92.9%) were the most consumed foods. Being a nonfarmer employee (AOR = 10.76, 95% CI = 1.03-112.35), not taking cotrimoxazole prophylaxis (AOR = 3.76, 95% CI = 1.02-14.37) and adults of age 18-27 years (AOR = 5.95, 95% CI = 1.18-30.07) were significant predictors of high dietary diversity. This study revealed that dietary diversity was a significant nutritional problem among HIV-positive adults in Lawra Municipal Hospital. Starchy staple foods and flesh food were the most consumed foods, while organ meats, dairy products, and eggs were eaten less. Having a secured salary paid job, not taking cotrimoxazole prophylaxis, and being a young adult were strong predictors of a high dietary diversity score. Therefore, efforts should be made to strengthen and improve the economic status and to educate these vulnerable groups on the need to adhere to cotrimoxazole prophylaxis uptake.

Tracking progress toward a climate-friendly public food service strategy: assessing nutritional quality and carbon footprint changes in childcare centers

BackgroundPublic food procurement and catering are recognized as important leverage points in promoting sustainable and healthy dietary habits. This study aimed to analyze changes in nutritional quality and carbon footprint (CF) of food service in childcare centers in the City of Copenhagen from 2018 to 2022, following a new climate-friendly food strategy in 2019. The strategy has a target of decreasing the CF of municipal food service by 25% before 2025 compared to a 2018 baseline.MethodsKey initiatives in the municipality’s strategy included creating guidelines for food-service providers to reduce their CF while ensuring meal nutritional quality and providing food professionals an advisory process to develop necessary competencies.In this quasi-experimental study, food procurement data from Copenhagen’s childcare centers (n = 356 [2022]) from 2018 and 2022 were combined with CF and nutrient composition data. Dietary CF and food and nutrient content were calculated per 10 MJ of energy and compared to guideline targets. Furthermore, data for 2022 were analyzed separately for institutions that had received an advisory process (n = 87) and those that had not yet (n = 269).ResultsOn average, the CF of the food procurement decreased by 15%, mainly driven by a decrease in ruminant meat purchases (-37%). While the procurement of plant-based protein sources (pulses, nuts, seeds) increased by 25%, it was still considerably below targets. Nutrient content did not substantially change, and recommendations for calcium, iron, vitamin D, sodium, and total and saturated fat were not met in either measurement year. Institutions that had received an advisory process had a 14% lower CF in 2022 than institutions that had not.ConclusionsWith the observed 15% CF reduction, Copenhagen’s childcare centers are on track to reach the 25% reduction goal outlined in the municipality’s food strategy by 2025. Nutritional quality was largely unchanged, but further efforts to increase especially the consumption of plant-based protein sources, while simultaneously reducing meat and animal-based fat, and maintaining sufficient dairy consumption, are needed to improve nutritional quality and reach the target CF reduction in the coming years. Providing training for food professionals could play an important role in seeing the changes through.
