The existing conditions of domestic agricultural production and the resulting products will not be able to fruitfully address the increasing food demand due to the limited fertile land and water resources in Saudi Arabia. Moreover, the escalating threat of a hotter climate, the deterioration in precipitation, and harsh droughts in Saudi Arabia have reduced the predictability of water management efficiency and resulted in the exhaustion of water bodies and serious degradation of ecosystems that have directly affected agricultural systems and indirectly, food security. This study also aims to assess the impact of water efficiency on food insecurity in Saudi Arabia. The study applied the Bayesian Vector Autoregressive (BVAR) model for the reference period for the data extended from 2000–2020. Likewise, we used both impulse response functions (IRFs) and forecasting variance error decomposition (FVED) through 1000 Monte Carlo simulations according to the BVAR model to examine both the response of food insecurity to the shocks on water management efficiency used for various purposes and the decomposition of error variance in food insecurity. The results show that food insecurity was not observed throughout this study. The results of the BVAR analysis indicate that in the short run, the coefficients of water use efficiency are significant based on the Food Insecurity Multidimensional Index (FIMI). Also, the BVAR model provides a better forecast with an interdependence on water use efficiency for agricultural purposes and FIMI. Moreover, the results obtained from IRFs have shown a significant effect of water efficiency on FIMI. Water use efficiency for agriculture and industrial purposes reduces food insecurity while increasing water for services use increases food insecurity. Water use efficiency is the key factor affecting food insecurity in the short run. The results reveal that the water use efficiency shocks will decrease food insecurity. The shocks experienced by food insecurity can be predicted as self-shock over a span of ten years. Emphasis is given to the task of water management that may support food security in Saudi Arabia through implementing and enhancing the water use efficiency as an integral part of achieving the SDGs in Saudi Arabia.

Rapid urbanization and population growth have increased the need for optimizing the location of health services in highly urbanized countries like Kingdom of Saudi Arabia (KSA). This study employs a multiple-criteria decision making (MCDM) approach, e.g., fuzzy overlay technique by combining the P-Median location-allocation model, for optimizing health services. First, a geodatabase, containing public hospitals, road networks and population districts, was prepared. Next, we investigated the location and services of five public hospitals in Jeddah city of KSA, by using a MCDM model that included a fuzzy overlay technique with a location-allocation model. The results showed that the allocated five hospitals served 94 out of 110 districts in the study area. Our results suggested additional hospitals must be added to ensure that the entire city is covered with timely hospital services. To improve the existing situation, we prioritized demand locations using the maximize coverage (MC) location problem model. We then used the P-Median function to find the optimal locations of hospitals, and then combined these two methods to create the MC-P-Median optimizer. This optimizer eliminated any unallocated or redundant information. Health planners can use this model to determine the best locations for public hospitals in Jeddah city and similar settings.

Background: For dental graduates, internships are a vital transitional phase that gives them the invaluable opportunity to close the gap between their academic studies and the reality of professional dentistry. Research on dental internships remains limited and most of the existing studies focus on the clinical aspects of dental internships with little attention given to dental interns' experiences overall. This study aims to bridge this gap in the literature by gaining an in-depth understanding of Saudi dental graduates' range of experiences as dental interns. Methods: To achieve the research objective, this study adopted a qualitative approach. Using purposive and snowball sampling, the study recruited 23 dental interns from Riyadh Province, Saudi Arabia, who had completed at least nine months of their internship. Data was gathered across three months via diaries and virtual semi-structured interviews based on participants' preferences. The data was then analysed thematically using an inductive analytical strategy. Results: The data analysis revealed three major themes and four sub-themes regarding the experiences of dental interns. The core three themes were "activities", "autonomy" and "transitioning to a balanced life" whereby interns have the time and freedom to explore their interests, rekindle their social lives and focus on self-care, resulting in a better work-life balance. Conclusion: This study suggests that dental interns will benefit from the retention and strengthening of key internship activities such as research, community work and clinical rotations. Additionally, the experiences of dental interns can be improved by encouraging interns to progress in their clinical training with a high level of autonomy. Also, due to the limited research in this area, further studies are required to improve our understanding of the lived experiences of dental interns and dental internships in general.

Emergency Medical Services (EMS) are crucial for immediate medical assistance during life-threatening situations. However, insufficient public awareness about EMS services can impede their effectiveness. This study aimed to assess EMS knowledge and trust among the population of Eastern Saudi Arabia while identifying factors contributing to low awareness. A cross-sectional study was conducted in Eastern Saudi Arabia from September 2022 to September 2023. The study included participants aged 18 to 60 from diverse backgrounds. Using a convenience sampling approach, data was collected using a validated questionnaire covering demographics, hypothetical scenarios, EMS knowledge, and trust in EMS. We conducted the Chi-square tests and logistic regression using Jamovi software, with significance levels set at p < 0.05. Our study yielded 435 participants; 55% were males. Gender-based analysis showed significant differences in responses regarding first aid provision and EMS services (P < 0.001). Expectations for EMS response times also varied by gender (P = 0.01). Knowledge-based analysis revealed that age and education significantly influenced EMS knowledge (P < 0.001). Respondents with EMS knowledge were more likely to know how to provide first aid, understand the importance of emergency number 112, and trust EMS (P < 0.001). Trust-based analysis showed age and education-related differences in EMS trust (P < 0.001). Respondents with EMS knowledge and awareness of emergency numbers displayed higher trust in EMS (P < 0.001). This study underscores the need for enhanced public awareness of EMS services in Eastern Saudi Arabia. Age, education, and gender emerged as critical factors affecting EMS knowledge and trust. Bridging this awareness gap necessitates tailored educational campaigns and continuous monitoring. Policymakers should prioritise EMS awareness within broader healthcare strategies, contributing to improved public health outcomes and community well-being. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic presented many psychological stressors which affected healthcare worker wellbeing. The aim of this study was to understand the factors that affect the wellbeing of healthcare professionals in the Kingdom of Saudi Arabia using Job-Demand and Resource (JD-R) Model. The proposal model consisted of demand factors (Work load—job demand, loneliness—personal demand), support factors (organizational support—job resource, and resilience—personal resource), mediators (burnout and work engagement), and outcome (wellbeing) A cross-sectional, descriptive study was conducted across 276 healthcare workers from hospitals and primary healthcare centers, including healthcare professionals, health associate professionals, personal care workers, health management and support personnel, and health service providers, and others between February-March 2022. The proposed model was tested using partial least squares structural equation modeling. Among the respondents, the majority were female (198, 71,7%), married (180, 65.2%), healthcare professionals (206, 74.6%), being more than 10 years in the profession (149, 51.6%), and non-Saudi nationality (171, 62.0%). Burnout accounted for a significant effect on wellbeing. Of the demands (workload and loneliness) and the resources (organizational support and resilience), workload had the greatest impact on burnout. Healthcare organizations should invest in reducing workloads and promoting resilience to reduce burnout and increase healthcare worker wellbeing. [ABSTRACT FROM AUTHOR]

Recent advances in interdisciplinary archaeological research in Arabia have focused on the evolution and historical development of regional human populations as well as the diverse patterns of cultural change, migration, and adaptations to environmental fluctuations. Obtaining a comprehensive understanding of cultural developments such as the emergence and lifeways of Neolithic groups has been hindered by the limited preservation of stratified archaeological assemblages and organic remains, a common challenge in arid environments. Underground settings like caves and lava tubes, which are prevalent in Arabia but which have seen limited scientific exploration, offer promising opportunities for addressing these issues. Here, we report on an archaeological excavation and a related survey at and around Umm Jirsan lava tube in the Harrat Khaybar, north-western Saudi Arabia. Our results reveal repeated phases of human occupation of the site ranging from at least the Neolithic through to the Chalcolithic/Bronze Age. Pastoralist use of the lava tube and surrounding landscape is attested in rock art and faunal records, suggesting that Umm Jirsan was situated along a pastoral route linking key oases. Isotopic data indicates that herbivores primarily grazed on wild grasses and shrubs rather than being provided with fodder, while humans had a diet consistently high in protein but with increasing consumption of C3 plants through-time, perhaps related to the emergence of oasis agriculture. While underground and naturally sheltered localities are globally prominent in archaeology and Quaternary science, our work represents the first such combined records for Saudi Arabia and highlight the potential for interdisciplinary studies in caves and lava tubes.

Background: Insufficient physical activity (PA) was estimated to cause 4.8% of deaths and 2.6% of disability-adjusted life-years (DALYs) due to noncommunicable diseases in Saudi Arabia in 2019. While Saudi Arabia is already achieving great improvements, we predict the health and economic burden of insufficient PA up to 2040 to present a case for policy makers to invest more in the uptake of PA. Methods: Using a population health model to estimate avoidable health loss, we identified four causes of health loss related to low PA (cardiovascular diseases, diabetes, breast cancer, and colorectal cancer) and estimated the deaths and DALYs from these causes. We projected the expected disease burden until 2040 under alternative assumptions about future PA levels and trends by using three health scenarios: baseline (no change in 2019 PA levels), intervention (81% of the population achieving sufficient PA levels), and ideal (65% of population: moderate PA, 30%: high PA, and 5%: inactive). We applied an "intrinsic value" approach to estimate the economic impact of each scenario. Results: Overall, we estimate that between 2023 and 2040, about 80,000 to 110,000 deaths from all causes and 2.0 million to 2.9 million DALYs could be avoided by increasing PA levels in Saudi Arabia. The average annual economic loss from insufficient PA is valued at 0.49% to 0.68% of the current gross domestic product, with an average of US$5.4 billion to US$7.6 billion annually till 2040. The most avoidable disease burden and economic losses are expected among males and because of ischemic heart disease. Conclusions: This study highlights that low PA levels will have considerable health and economic impacts in Saudi Arabia if people remain inactive and do not start following interventions. There is an urgent need to develop innovative programs and policies to encourage PA among all age and sex groups. [ABSTRACT FROM AUTHOR]

Background: Globally, hypertension is among the leading causes of premature mortality. It is a noncommunicable disease characterized by a persistent state of raised blood pressure that increases the risk of cardiovascular diseases and medical conditions affecting the brain and kidneys. There is a paucity of thorough hypertension knowledge assessment among hypertensive patients in the Jazan region of Saudi Arabia. Thus, this study aimed to assess overall and specific knowledge about hypertension and to identify predictors of inadequate knowledge. Methods: A cross-sectional study was conducted in the Jazan region of Saudi Arabia between February and April 2023. Data were collected using an online, self-administered questionnaire divided into two sections. In the first section, the characteristics of the participants were collected. In the second section, the Hypertension Knowledge-Level Scale was used to measure overall and specific knowledge areas (subdimensions). The overall and subdimensional means were tested using Mann–Whitney U and Kruskal–Wallis H tests. Furthermore, the binary logistic regression was conducted to determine inadequate knowledge predictors. Results: In all 253 hypertensive patients were eligible for participation; almost 70% of whom were male. The mean age of the participants was 45 years (±14.7), and their mean overall knowledge score was 17.60 (±5.09), which was equivalent to 67.7% of the maximum score. In addition, 40.7% of participants had an adequate level of hypertension knowledge. The complications subdimension level of knowledge was borderline optimal. At the same time, an adequate knowledge level was detected only in the lifestyle subdimension. Conclusion: Most patients showed inadequate levels of knowledge related to hypertension management. Diet, medical treatment, disease definition, drug compliance, and complications were subsequently the least knowledgeable subdimensions among the study population. Therefore, these subdimensions should be prioritized when planning hypertension educational interventions and during follow-up sessions, especially for patients of younger age groups and those with lower educational levels.

Background: Effective nurse leadership enhances nurse welfare, improves patient care, and increases organisational success. A lack of adequate, supportive leadership significantly contributes to many nurses leaving the profession. Nurse managers need to prioritise engagement and retention as significant focus areas to address the nursing shortage in Saudi Arabia and accomplish the national program's objectives. Aim: To examine the correlation between the leadership styles of clinical nurse managers and staff engagement. Method: This study used a descriptive, cross-sectional, correlational design. The leadership styles of clinical nurse managers were evaluated using the Multifactor Leadership Questionnaire (MLQ-5X). Work engagement was assessed using the Utrecht Work Engagement Scale (UWES). Questionnaires were distributed to 450 nurses in four public hospitals in western Saudi Arabia. Non-probability convenience sampling was used to collect the data. Results: A total of 278 nurses from a range of clinical areas participated in the survey, which revealed that the leadership styles of clinical nurse managers positively or negatively impact nurse work engagement. Most clinical nurse managers exhibit transformational leadership, followed by transactional, then passive-avoidant styles. Respondents displayed a high level of work engagement, emphasising the positive impact of transformational and transactional leadership on work engagement outcomes. The findings showed significant differences in leadership styles and work engagement levels between Saudi and non-Saudi nurses across various dimensions. Conclusion: Understanding the effect of leadership styles employed by nurse managers on work engagement can positively impact staff retention rates and the quality of patient care. Nurse managers should participate in training programs to enhance their practical leadership skills to enhance the work engagement levels of nurses. Implication: Nurse work engagement can be improved by establishing training programs that promote effective leadership and highlight the significance of various leadership styles and their subsequent impact on nurse work engagement. Nursing students should receive education on leadership styles. Nursing leaders should be given access to mentoring programs and opportunities for career advancement to support the introduction of effective leadership styles. [ABSTRACT FROM AUTHOR]

Introduction: Measuring and monitoring physical growth is a key element in assessing children's health. The physical and mental development of a growing child are indicators of good health and nutrition. This study aimed to explore the patterns of growth parameters among children under 5 years old attending primary health care centres (PHCCs) in rural northern Abha. Feeding habits during the first 2 years of life were also assessed. Method: This study was conducted on 1–5 April 2022 in all (PHCCs) in Billasamr and Ballahmar, two neighbourhoods of northern Abha. The investigator designed a form for collecting each child's age (months), weight (kilograms), gender, birth order, number of family members, type of feeding (exclusive breastfeeding, exclusive bottle feeding, or mixed feeding), and duration of exclusive breastfeeding. Results: Gender affected the body weight of Saudi infants, as boys weighed significantly more than age-matched girls. Birth order also affected body weight. During the first and third years of life, Saudi children's body weight was not significantly affected by feeding type. During the second and fifth years of life, formula-fed children weighed more than breastfed or combination-fed children. However, during the fourth year of life, body weight was highest in combination-fed children. Conclusion: Growth patterns over time, established from multiple data points, must be used in conjunction with other medical and family history to evaluate appropriate growth. Recording and tracking body size, especially recumbent length and weight, as part of well-baby care is critical for any assessment of child wellbeing and health status. [ABSTRACT FROM AUTHOR]

Background: It is crucial to take into account the concerns of dental patients about their prosthodontic needs when planning the course of treatment. However, there is a dearth of research that examines these needs among adult dental patients. Objectives: This study aims to translate and validate the perceived prosthodontic treatment need scale (PPTN) in Arabic. Methods: The 17-item PPTN scale was translated from English into Arabic and completed by 206 patients seeking prosthodontic treatment in a dental hospital in Saudi Arabia. Data collection was carried out in September and October 2023. Exploratory factor analysis (EFA) was used to ascertain the underlying factor structure; a unidimensional scale was hypothesised and tested using confirmatory factor analysis (CFA), including several multiple model fit indices. The assessment of reliability was conducted using Cronbach's alpha. The convergent and discriminant validity of the final scale were examined. Results: EFA produced an 11-item scale distributed into three factors that explain 65.43% of the total variance with eigenvalues > 1. All items showed acceptable reliability, ranging from 0.65 to 0.84. The first factor pertained to social issues, while the second item was concerning dental appearance. Lastly, the third factor included functional difficulties associated with tooth loss or dental problems. The results of the CFA demonstrate a satisfactory level of model fit, with the standardised factor loadings ranging from 0.51 to 0.89. Convergent and discriminant validity of the model factors were established. Conclusion: The translated questionnaire was deemed legitimate and would be useful in comprehending patients' perceived treatment requirements, hence contributing to the advancement of prosthodontic research and practical implementation.

Childhood and adolescent overweight and obesity are one of the most serious public health challenges of the 21st century. A range of genetic, family, and environmental factors, and health behaviors are associated with childhood obesity. Developing models to predict childhood obesity requires careful examination of how these factors contribute to the emergence of childhood obesity. This paper has employed Multiple Linear Regression (MLR), Random Forest (RF), Decision Tree (DT), and K-Nearest Neighbour (KNN) models to predict the age at the onset of childhood obesity in Saudi Arabia (S.A.) and to identify the significant factors associated with it. De-identified data from Arar and Riyadh regions of S.A. were used to develop the prediction models and to compare their performance using multi-prediction accuracy measures. The average age at the onset of obesity is 10.8 years with no significant difference between boys and girls. The most common age group for onset is (5-15) years. RF model with the R2 = 0.98, the root mean square error = 0.44, and mean absolute error = 0.28 outperformed other models followed by MLR, DT, and KNN. The age at the onset of obesity was linked to several demographic, medical, and lifestyle factors including height and weight, parents' education level and income, consanguineous marriage, family history, autism, gestational age, nutrition in the first 6 months, birth weight, sleep hours, and lack of physical activities. The results can assist in reducing the childhood obesity epidemic in Saudi Arabia by identifying and managing high-risk individuals and providing better preventive care. Furthermore, the study findings can assist in predicting and preventing childhood obesity in other populations., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Alanazi et al.
