Many researchers have reported that vitamin D can affect brain development as well as brain function. The prevalence of vitamin D deficiency in the Saudi population is 81% and it is more among women than among men. Though many studies have been done to find out the factors influencing the academic performance of Health sciences students, there is not adequate evidence regarding the influence of vitamin D level on academic performance. Therefore, this study aims to find out the association if any, between the vitamin D level and academic performance of health sciences students.

After obtaining the ethical committee approval, the data was collected from 86 female medical students, 70 female applied medical sciences students and 57 nursing students of Northern Border University. The detailed questionnaire contained the aim of the study, demographic characteristics and academic performance predictors such as self-efficacy, academic motivation, academic engagement and social engagement. The vitamin D levels were measured by an enzyme-linked immunosorbent assay (ELISA) machine (BioTek) which is available in the local hospital. The multiple linear regression analysis was used to find out the association between vitamin D levels and academic performance.

This study showed that vitamin D level had a significant association with the overall performance of the students as well as their self-efficacy.

Since there is a lot of stress among health sciences students due to subject overload and inadequacy of time, the health aspects are often overlooked. This study emphasizes the importance of early screening of vitamin D levels and early intervention in those with low vitamin D levels for better academic performance.

There is very little awareness of the impact of vitamin D deficiency on academic motivation, academic engagement, social engagement and self-efficacy among medical and health sciences students. This study can increase awareness.

There are very few studies done to find out the association between Vitamin D level and academic performance. This study is unique as it has highlighted the association between vitamin D level and grade point average (GPA) and also the association between vitamin D level and academic predictors such as self-efficacy, academic motivation, academic engagement and social engagement.

This study aims to evaluate the caffeinated drinks, levels of vitamin D and calcium in the blood, and their relationship to bone mineral density (BMD) in osteoporotic women in Al-Ahsa Saudi Arabia.

This study included 85 women over approximately 18 months with ages ranging from 40 to 70 years who were evaluated in the laboratory via blood analysis. Moreover, sociodemographic data and information on health and nutritional awareness were collected via a questionnaire. The BMD was measured by dual-energy X-ray absorptiometry (DXA) and considered osteopenia when the T value total of the lumbar spine or hip was between −1 and −2.5 and osteoporosis < −2.5. Blood levels of vitamin D and calcium were measured via blood analysis.

There were 54.1% and 45.9% of women who suffered from osteoporosis and low BMD, respectively. There was a significant difference in the number of osteoporotic, and low bone mineral mass groups in marital status (p = 0.04), but no difference was found in age and educational level. A significant difference (p = 0.01) between low bone mass and osteoporosis groups in heights. BMD was significantly and negatively correlated with vitamin D in the blood in individuals with osteoporosis (r = −0.358, P = 0.014). In addition, there was a significant negative correlation between calcium in the blood and total samples (r = −0.355, P = 0.0578). There was a negative significant relationship between calcium supplements and BMD in individuals with low BMD (rt = −0.279, P = 0.041). There was a significant association between cola intake with the occurrence of low BMD (p = 0.027), whereas tea drinking was not associated with risk in both groups.

The study indicated that there is a direct relationship between osteoporosis and low bone mass with different variables. This study was conducted to address the lack of research related to the levels of vitamin D and calcium in the blood and their relationship with BMD in women with low BMD and osteoporosis in Al-Ahsa province-KSA.

The purpose of this paper is to assess the socioscientific issue (SSI) method as a way of improving seventh graders’ nutrition know-how on dietary supplements (DS), and to describe how students experience learning nutritional issues through the SSI method.

Participants were seventh graders from three different classes (n=43). Health education intervention lasted 7 h and it embodied the three-staged model: the scenario, the inquiry and the decision-making stages. The study was qualitative in nature. The data were collected through a questionnaire before and after the intervention. The data were analyzed using summative content analysis.

Intervention tended to deepen students’ know-how on vitamins and rational use of DS. Students’ experiences of learning nutritional issues through the SSI method were generally positive. The scenario stage was considered current and authentic. The inquiry stage and decision-making stage helped in understanding the societal connections between the study task and the rational use of DS.

SSI method enhances students’ knowledge about the rational use of DS. E-learning environment gave students possibilities to work collaboratively. Especially, possibilities to discuss with peers and share own experiences supported learning.

To solve the need of dietary supplements (DS) is a complex nutritional issue for society and for individuals. Since consumption of special diets has increased among adolescents, the rational consumption of DS is relevant and interesting learning topic at secondary school.

This systematic review paper aims to investigate seasonal ambient change’s impact on the incidence of falls among older adults.

The population, exposure, outcome (PEO) structured framework was used to frame the research question prior to using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework. Three databases were searched, and a total of 12 studies were found for inclusion, and quality appraisal was carried out. Data extraction was performed, and narrative analysis was carried out.

Of the 12 studies, 2 found no link between seasonality and fall incidence. One study found fall rates increased during warmer months, and 9 of the 12 studies found that winter months and their associated seasonal changes led to an increase in the incidence in falls. The overall result was that cooler temperatures typically seen during winter months carried an increased risk of falling for older adults.

Additional research is needed, most likely examining the climate one lives in. However, the findings are relevant and can be used to inform health-care providers and older adults of the increased risk of falling during the winter.

The purpose of this paper is to investigate the overall campaign reach and impact of the ABCs of Mental Health in Denmark; a secondary objective is to investigate how mental health-promoting beliefs and actions are associated with good mental health.

A questionnaire was administered to two representative cross-sectional samples of the Danish population (1,508 respondents in 2019; 1,507 respondents in 2021) via an online survey. The data were subsequently pooled together into one sample consisting of 3,015 respondents. In addition to questions pertaining to campaign reach and impact, the questionnaire also included a validated scale for mental well-being and questions about beliefs and actions in regard to enhancing mental health.

About 7.6% had been reached by the campaign (familiar with ABC name or messages), or 11.9% when also counting familiarity with campaign slogans. Among these, respondents reported (proportions in parentheses) that the campaign had 1) made them reflect on their mental health (74.2%), talk to friends and family about mental health (35.5%), given them new knowledge about what they can do to enhance mental health (78.4%), or take action to enhance their own mental health (16.2%). An internal well-being locus of control and proactive behaviours towards enhancing mental health are shown to be associated with higher mean scores on mental well-being, lower odds of low mental well-being and higher odds of higher mental well-being.

An internal well-being locus of control and proactive behaviours towards enhancing mental health are suggested to both prevent low levels of mental well-being and promoting high levels of mental well-being. The results indicate that the ABCs of Mental Health campaign may be implemented to promote such beliefs and actions universally throughout the population.

This paper aims to assess the consumption of dairy products in Kuwaiti children, and develop and validate a semi-quantitative food frequency questionnaire to measure dairy product consumption.

This cross-sectional study was based on a sample of child–parent dyads (n = 150). A dietary assessment questionnaire on local dairy products consumed by preschool and preadolescent children was developed. Serving and portion sizes were evaluated on the basis of the guidelines of the United States Department of Agriculture and the American Academy of Pediatrics to calculate median intake levels of three age groups (3-5, 6-8 and 9-11 years).

All children met or exceeded the recommended daily servings of dairy products for their age and sex. Dairy product intake was often from processed dairy including milk-based desserts, flavored milk and cheese. Compared to boys, girls consumed more yogurt (15.5 per cent vs 14.2 per cent, p = 0.001) and milk-based desserts (15.5 vs 14.3, p = 0.001). In boys, flavored milk contributed more to the total dairy intake than in girls, especially in 6-8-year-olds (21.8 per cent vs 18.9 per cent, p = 0.021). Weight status was not associated with dairy product intake in either sex.

This is the first study that quantifies dairy product consumption in Kuwaiti children and provides insight into sex-specific trends in dairy product selection. The findings of this study may help in investigating relationships between dairy product consumption in children and disease risk factors, and are important for the development of local dietary guidelines for children.

Milk and yoghurt provide essential sources of nutrition throughout the life cycle in the Irish diet. Health claims on dairy product labels were popular in the 1980s, and since the introduction of the nutrition and health claims (NHC) Regulation (EC) No 1924/2006 in 2007, many new regulated claims have been used to communicate product benefits. Meanwhile, COVID-19 and the Farm to Fork strategy have heightened consumer awareness of health issues. All of these factors have contributed to a change in our food environment and interest in health. In addition, the European Commission is working to introduce a legislative proposal on nutrient profiles (NP) to restrict the use of NHC on foods that are high in salt, fat or sugar. This qualitative study aims to research knowledge on adults’ attitudes, perceptions and behaviour towards NHC on dairy products.

The study used a thematic analysis using transcripts from a series of discussion groups, attended by adults (n = 24). The participants also completed an introductory questionnaire.

The study noted positive attitudes towards dairy protein. This attitude was common across age, gender or life stage. There were misperceptions regarding yoghurt composition and health benefits. There were negative perceptions of low-fat nutrition claims on yoghurt, which led to a preference for full-fat dairy products. This requires further insight and research.

Participants from a wider socio-demographic group could have broadened the research limits of this project.

These findings will interest policymakers, regulators, dieticians and the food industry.

22q11.2 deletion syndrome (22q11DS) is a risk factor for psychiatric illnesses, including schizophrenia and anxiety. Small studies have shown that several neuroleptic medications are effective in treating psychosis in this population, but are also associated with an increased risk of adverse effects - particularly, seizures. In this case, we discuss a 34-year-old patient presenting with late onset schizophrenia, which ultimately led to her diagnosis of 22q11DS. Subsequent management of the patient's psychosis with asenapine was complicated by concurrent anxiety and panic disorder; thus, we examine the role of anxiolytic therapy in conjunction with antipsychotics in this patient population.

The main objective of this study is to assess the applicability and robustness of the information motivation behavioural skills (IMB) model in determining dietary supplement usage of pregnant and breastfeeding women. More specifically, we examine the indirect effects of online social capital and internet use for health information on dietary supplement usage through self-efficacy and the moderating role of educational attainment.

Data was collected from 415 pregnant and breastfeeding Italian women using a self-administered questionnaire. Hypotheses were tested using Hayes's (2013) PROCESS macro for SPSS.

Internet use for health information is directly associated with dietary supplement usage. Online social capital and internet use for health information positively influence dietary supplement usage through self-efficacy. However, the results from moderated mediation analyses show that the mediation effects are moderated by educational attainment so that indirect relationships were stronger among women with a lower level of education than among those with a higher level of education.

Dietary supplement marketers and public health agencies can develop and implement dietary supplement promotional materials and interventions by disseminating information through the internet and social media and by strengthening social ties on online networking sites.

The originality of this study lies in the use of the IMB model as a theoretical framework to examine the mediating role of self-efficacy and the moderating role of education in explaining the mechanism of how online social capital and internet use for health information influence dietary supplement usage.

In the recent past, academic researchers have noted the quantity of food wasted in food service establishments in educational institutions. However, more granular inputs are required to counter the challenge posed. The purpose of this study is to undertake a review of the prior literature in the area to provide a platform for future research.

Towards this end, the authors used a robust search protocol to identify 88 congruent studies to review and critically synthesize. The research profiling of the selected studies revealed limited studies conducted on food service establishments in universities. The research is also less dispersed geographically, remaining largely focused on the USA. Thereafter, the authors performed content analysis to identify seven themes around which the findings of prior studies were organized.

The key themes of the reviewed studies are the drivers of food waste, quantitative assessment of food waste, assessment of the behavioural aspects of food waste, operational strategies for reducing food waste, interventions for inducing behavioural changes to mitigate food waste, food diversion and food waste disposal processes and barriers to the implementation of food waste reduction strategies.

This study has key theoretical and practical implications. From the perspective of research, the study revealed various gaps in the extant findings and suggested potential areas that can be examined by academic researchers from the perspective of the hospitality sector. From the perspective of practice, the study recommended actionable strategies to help managers mitigate food waste.

The authors have made a novel contribution to the research on food waste reduction by identifying theme-based research gaps, suggesting potential research questions and proposing a framework based on the open-systems approach to set the future research agenda.
