Background: Studies have shown that food insecurity is associated with electronic vapor products (EVP) use in adults; however, an understanding of this relationship in adolescents is needed to inform prevention efforts in this age group. Aim: Examine the relationship of food insecurity with EVP use patterns, frequency and source of acquisition in high school students. Methods: This cross-sectional study used Youth Risk Behavior Survey (YRBS) 2019 data from states that incorporated the YRBS' optional food insecurity question. The data included 42,154 high school students with complete information on food insecurity and two EVP-related questions. Responses to EVP-related questions identified "ever users," "current users," "former users," "current dual EVP-cigarette users," and assessed "frequency of EVP use among current users" and "source of EVP acquisition." Logistic regression examined associations of food insecurity with EVP-related outcomes. Results: The proportion of high school students who ever used EVP was 48.3% and the proportion of food-insecure students was about 12%. Food security status significantly differed by race/ethnicity of students, such that the proportion of food insecure students classified as "non-Hispanic White" was lower than the proportion of food secure students classified as "non-Hispanic White." Food insecurity was significantly associated with greater odds of ever EVP use (odds ratio (OR) = 1.75; 95% confidence interval (CI) = (1.55, 1.96)), current EVP use (OR = 2.07; 95% CI = (1.80, 2.37); using never users as reference category) and current dual use of EVP and cigarettes (OR = 2.91; 95% CI = (2.38, 3.55)). Food insecurity also was associated with greater odds of current EVP use (OR = 1.54; 95% CI = (1.28, 1.84)) when former users were used as reference category. In current users, food insecurity was related to greater odds of daily EVP use (OR = 1.40; 95% CI = (1.14, 1.70)) compared to occasional use. Conclusions: Study findings imply that efforts targeting prevention/cessation of EVP use should consider reducing food insecurity in high school students.

Background: Globally, one-third of pregnant women are at risk of iron deficiency, particularly in the African region. While recent findings show that iron and folate supplementation can lower the risk of adverse birth outcomes and childhood mortality, our understanding of its impact in Africa remains incomplete due to insufficient evidence. This protocol outlines the systematic review steps to investigate the impact of oral iron and folate supplementation during pregnancy on adverse birth outcomes, neonatal mortality and infant mortality in Africa.

Methods and analysis: MEDLINE, PsycINFO, Embase, Scopus, CINAHL, Web of Science, and Cochrane databases were searched for published articles. Google Scholar and Advanced Google Search were used for gray literature and nonindexed articles. Oral iron and/or folate supplementation during pregnancy is the primary exposure. The review will focus on adverse birth outcomes, neonatal mortality and infant mortality. Both Cochrane Effective Practice and Organization of Care and Newcastle-Ottawa Scale risk of bias assessment tools will be used. Meta-analysis will be conducted if design and data analysis methodologies permit. This systematic review and meta-analysis will provide up-to-date evidence about iron and folate supplementation's role in adverse birth outcomes, neonatal mortality and infant mortality in the African region.

Ethics and dissemination: This review will provide insights that help policymakers, program planners, researchers, and public health practitioners interested in working in the region.

Introduction: One of the dimensions of food security has to do with economic access to food. Aim: Propose a methodology that allows evaluating economic access to food in Argentina for the elderly population. Methods: Dietary guides for the Argentine population are used. Meanwhile, the food consumption patterns observed in the elderly population in Argentina are considered from a household expenditure survey, from which implicit food prices can also be obtained. Results: Six dietary plans corresponding to different regions of the country are designed and evaluated and it is found that they would be affordable only in two of the six regions analyzed. Conclusion: in the Metropolitan, Pampas, Cuyo, and Northeast regions the cost of the ideal basket is higher than food spending, fundamentally in the Northeast region where food spending should increase by 25%.

Aim: Few health checkup studies have reported lifestyle habits and examination results before and during the COVID-19 pandemic. We compared lifestyle habits and examination results surveyed before and during the COVID-19 pandemic. Methods: Five hundred and ten and 396 participants attended the health checkup in 2019 and 2022, respectively. The median age of females was 65 in 2019 and 2022, and that of males was 68 in 2019 and 69 in 2022. We investigated dietary and exercise habits, alcohol consumption, sleeping situation, and examination results, including body mass index (BMI), smell function, and blood examination results before and during the COVID-19 pandemic in a rural area in Japan. Results: An ordinal logistic regression analysis revealed that the intake frequency of vegetables and marine products was significantly less in 2022 than in 2019 after adjusting age and sex; green leafy vegetables (p = .016), fish (p = .002), and other marine products, including squid, shrimp, crabs, and octopus (p = .008). Alcohol consumption amount increased significantly in 2022 than in 2019 in men who drank beer (p = .007) and chuhai (p = .040). Albumin, hematocrit, cholesterols, and uric acid decreased, but serum calcium increased significantly in 2022 than in 2019 after adjusting age and sex. BMI and hemoglobin A1c were not significantly different between 2019 and 2022. A decrease in subjective smell feeling and smell test results was associated with decreased intake frequency of vegetables. Conclusion: Both dietary habits and blood examination results changed significantly during the COVID-19 pandemic in a rural area in Japan.

Background: Health professionals, including dietitians, should adapt their clinical daily practice to evidence-based practice (EBP), but this does not happen often in daily practice. The aim of this study was to investigate the current status and barriers to evidence-based practice among dietitians. Methods: This was a mixed-method, cross-sectional, national study (questionnaire and focus group) performed on working and registered dietitians, both self-employed and employed by public hospitals. The main outcomes were EBP knowledge, frequency of use, and proficiency scores. Barriers to EBP implementation were also collected, as well as qualitative information from the focus group. Results: Forty-three dietitians were enrolled from August to November 2021 in Italy. Overall, EBP knowledge was moderate/good. Younger dietitians (< 50 years old) obtained better results than their older colleagues. A similar trend was observed in terms of seniority. There was a discrepancy between EBP knowledge and perception of EBP implementation: the worst scores were obtained by participants who claimed an already complete integration of EBP. The average frequency of EBP use was moderate, with higher scores in dietitians ≥ 50 years old and with seniority ≥ 20 years. EBP proficiency instead was poor. The focus group revealed a lack of time and resistance to change as the main barriers. Conclusion: The importance of EBP is well-acknowledged, but it is not correctly implemented yet, because of identified barriers that need to be fixed. These barriers include a lack of dedicated time, inadequate EBP training, and resistance to change, especially in hierarchical environments.

Background: Manipulation of macronutrient intake and exercise can alter overall energy consumption and potentially body composition. Aim: The purpose of this study was to manipulate the macronutrient content of breakfast before exercise to investigate the impact on exercise energy expenditure and postexercise energy intake (EI). Methods: Twelve active men were recruited, 11 finished the study protocol (age: 28 ± 9 years; VO₂max: 56 ± 5 ml·kg^-1·min^-1). In a randomized crossover design, each participant completed 4 trials, 3 consisting of a specific breakfast (protein, PRO; carbohydrate, CHO; noncaloric; NON-CAL) followed in 1 h by a 45 minutes moderate intensity treadmill exercise protocol. The fourth trial consisted of breakfast and no exercise (CON). An ad-libitum lunch and food for the rest of the day were provided and assessed for EI. Measures included resting metabolic rate pre- and postbreakfast along with oxygen uptake (VO₂) during and after exercise, along with hunger scales, and blood measures of glucose, insulin and plasma-PYY prebreakfast, pre-exercise, postexercise, and 60 minutes postexercise. Results: Fat oxidation was highest during exercise in the NON-CAL (0.57 g·min^-1) trial with similar levels of fat oxidation between PRO (0.50 g·min^-1) and CHO trials (0.48 g·min^-1). Hunger was not affected by PRO intake or exercise, nor was appetite hormones and glucose. EI at lunch and dinner was not significantly different between trials. Conclusion: Pre-exercise PRO intake did not modify fat oxidation during exercise, did not lead to a larger VO₂ versus CHO, nor did it attenuate EI postexercise.

Background: Nuts and seeds are among the leading causes of food allergy. Effective food allergy management hinges on the ability to identify and avoid relevant foods.

Aim: To evaluate the nut/seed recognition ability in both children and mothers.

Methods: Primary caregivers (mothers) and their children (6-18 years old) with/without food allergies were shown photographs of nuts/seeds, and their products with visible/hidden allergens to assess their ability to recognize accurately.

Results: A total of 196 children and 184 mothers participated. The median ages of the children and mothers were 7.6 (6.8-10) and 37.8 (33.1-41.5) years, respectively. Over 75% of the children/adolescents and over 90% of the mothers accurately identified the kernel forms of nuts/seeds, except pine nuts. Walnuts, hazelnuts, almonds, and cashews were the most accurately recognized kernel forms by both populations. Generally, the kernel forms were recognized 5-20% more accurately than their in-shell forms, followed by products with visible and hidden forms, respectively. Some Turkish culinary-specific products with visible/hidden allergens were recognized as frequently as the kernel/in-shell forms by both study groups. Although there was a similar recognition pattern between study groups and subgroups (nut/seed allergy, other food allergy, controls), higher rates of recognition were found in mothers than in their children and adolescents than in schoolchildren.

Conclusion: In Eastern Mediterranean region, nuts and sesame seeds are highly recognized by both mothers and their children. Accurate identification of these foods is likely a culinary feature, but not the result of increased awareness. More information is needed on whether this ability reduces the risk of exposure.

Background: Vitamin D supplementation practices (dose and frequency) are relatively unknown in the Scottish population, with no recent up-to-date data available. Reassessing current knowledge, practices, and awareness of vitamin D supplementation following a national health campaign in 2020 by Food Standards Scotland on vitamin D is warranted. Aim: This article aims to present the knowledge and awareness of vitamin D, and current vitamin D supplementation practices in adults living in Scotland. Methods: A cross-sectional study was performed between June and July 2022 using an online survey adapted from previous work on assessing knowledge of vitamin D in adults. Participants aged 18+, living in Scotland for ≥6 months were eligible to participate. Scores for knowledge were calculated as a percentage. Univariate associations between demographic and supplement use were established by χ²-test and logistic regression performed to predict factors associated with daily vitamin D intake. Results: Four hundred and three participants (72.7% female), mean age 36.4 (±14.2 years), completed the study. Awareness of vitamin D was very high (99.5%) but the mean overall knowledge score was poor (31.4 ± 15.3%), with those with a university degree more likely to have knowledge scores at/above the mean compared with those with lower levels of education, χ²(1, N = 393) 10.7, p = 0.001, odds ratio (OR) = 2.1 (95% confidence interval (CI) 1.7-2.7). Finally, 64.3% took vitamin D supplements, of which 37.5% took them daily during winter months, with only 7.4% taking the recommended daily dose. Conclusion: The current study highlights the need to improve both knowledge of vitamin D and practices of vitamin D supplementation during the autumn and winter months in Scotland.

Background: Results of studies on the effects of plant and animal proteins on lipid profile are controversial. So we aimed to assess the relationship between plant and animal protein intake with lipid profile and novel anthropometric indices in healthy individuals.

Method: In this cross-sectional study, 236 participants have selected from Shiraz medical centers (Iran) through random cluster sampling. Food intakes were assessed using a 168-items food frequency questionnaire (FFQ). Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglyceride (TG) were measured. Anthropometric indices including a body shape index (ABSI), abdominal volume index (AVI), buddy roundness index (BRI), and conicity index (CI) were calculated.

Results: In the crude and fully adjusted models, more consumption of plant proteins was associated with TG levels (OR = 2.31; 95% CI: 1.08, 4.95; P = 0.03 and OR = 2.39; 95% CI: 1.03, 5.15; P = 0.04). Also, there was a significant direct association between plant proteins and BRI in the curd model (OR = 3.55; 95% CI: 1.32, 9.54; P = 0.01), and after adjusting for age and energy intake (OR = 3.32; 95% CI: 1.21, 9.14; P = 0.01). More consumption of plant proteins was related to higher CI in the crude model (OR = 3.06; 95% CI: 1.12, 8.31; P = 0.03), but not in the fully adjusted model.

Conclusion: We found that a higher intake of plant proteins was associated with a higher TG level, BRI, and CI index. However, more research is needed to confirm these relations and provide the evidence needed to exert these findings into clinical practice.

To date, the primary and only treatment recommended for effective management of celiac disease (CD) is adherence to a strict gluten-free diet (GFD) which entails a new approach to eating that affects the social quality of life (QoL) and physical activity (PA) of patients. This cross-sectional study aimed at assessing the social QoL and PA of adult Lebanese CD patients aged between 18 and 59 years old who are following a GFD. An online CD questionnaire was administered to 136 Lebanese celiac participants on a GFD. The findings of this study show a significant association between celiac patients following a GFD and their social QoL (P-value = 0.0001). The results also showed a significant association between the same population and their PA (p-value = 0.0001). Further awareness-raising and learning activities about gluten-free products are needed to improve the adherence to a strict GFD to facilitate its availability to the Lebanese population.
