Dental decay in children and the link to weight status: A cross-sectional analysis of national school health data.

Recent national reports have indicated an increasing trend of dental decay among school-aged children. National school-based data are required to guide decision-making to ensure effective public health efforts to manage dental decay. This study aimed to assess the prevalence of dental decay among school-age children in Saudi Arabia and explore the possible link between dental decay and weight status. This was a cross-sectional analysis of a national sample including 1,134,317 Saudi children in the 1st, 4th, 7th, and 10th grades who participated in a national school screening program. Data for weight, height, body mass index (BMI), dental decay prevalence, and decayed, missing, and filled teeth (DMFT) index were analysed. An independent t-test, one-way analysis of variance, and chi-square test were used to compare the means, while Pearson's r correlation and multiple linear regression were used to examine the relationships between the study variables. The prevalence of dental decay was 24.20%, and dental decay was the highest among female students (26.5%), students in primary school (25.9%), students living in the eastern region (35.2%), in the administrative capital (27.6%), and in rural areas (23.4%). Dental decay was the highest among students who were underweight. Female sex and living in rural areas significantly predicted higher DMFT while being overweight/obese significantly predicted lower DMFT. Dental decay is highly prevalent among underweight students, female students, and students living in rural areas and the eastern regions of Saudi Arabia. To reduce the prevalence of dental decay and related health disparities, dental health screening programs should be designed to detect dental decay early among children at high risk due to abnormal BMIs and sociodemographic factors. In addition, dental health screening and management programs should utilize standardized dental decay assessment methods and ethnically representative growth charts.

The shifting patterns of childhood obesity: Insights from national school screening data.

Background: Recent reports indicated an increasing prevalence of obesity among children and adolescents in Saudi Arabia, making it an impending national epidemic. However, obesity prevalence data in children and adolescents in Saudi Arabia are largely inconsistent. Objectives: This study analyzed and compared the prevalence of obesity among a national sample of children and adolescents across sexes, school grades, regions, and city types in Saudi Arabia using the Growth Charts for Saudi Children and Adolescents. Methods: Weight, height, and body mass index (BMI) data from 1 134 317 children in first, fourth, seventh, and tenth school grades who participated in the national school screening program were analyzed cross-sectionally. BMI values were classified using the Growth Charts for Saudi Children and Adolescents. Results: Nearly 10.4% of students were overweight, 10.7 % were obese, and 4.50% were severely obese. Male students had a higher prevalence of overweight and obesity than their female counterparts. The prevalence of overweight and obesity was the highest among students in intermediate school, the Central region, and administrative capitals. Conclusion: Managing childhood obesity is challenging due to its multifaceted nature Therefore, utilizing clinical and community-based participatory approaches is essential to develop nationwide obesity prevention and management program that is effective and sustainable. This program must utilize dynamic BMI surveillance systems using ethnically representative growth references, conduct national pediatric obesity research with careful consideration for demographic and regional differences, lead targeted pediatric obesity awareness campaigns, provide obesity management interventions in a pediatric multi-disciplinary clinic, and evaluate the program outcomes periodically.

Quality of life among schoolchildren with type 1 diabetes mellitus and the satisfaction of their guardians towards school health care in Saudi Arabia.

AIMS: This study aimed to assess the quality of life of schoolchildren with type 1 diabetes mellitus (T1DM) and determine their guardians' satisfaction of diabetes health care in Saudi Arabian schools. METHODS: A cross-section multicenter study was conducted from February to July 2022 among Schoolchildren with T1DM in Saudi Arabia. The study included T1DM school children aged 6-18 years. The patients' health-related quality of life (HRQoL) data were collected and determined using a modified version of the PedsQL 3.0 Diabetes Module. RESULTS: The grand total median PedQL-DM score among the included participants (N = 283) was 64.7, while items related to diabetes symptoms and diabetes management were 61.1 and 68.7, respectively. Schoolchildren who have lower HbA1c levels and take care of regular monitoring of their blood glucose showed significantly better quality of life concerning diabetes symptoms. A significant number of guardians claimed they were not satisfied with the current status of diabetes management at schools. CONCLUSIONS: The overall HRQoL among schoolchildren with T1DM was average and acceptable to some extent. The PedsQL-DM median score was higher among those who received health care during school time. The guardians' satisfaction of diabetes health care was low, emphasizing the role of health clinics in schools.

The Association Between MTHFR C677T Gene Polymorphism and Repeated Pregnancy Loss in Arabic Countries: a Systematic Review and Meta-Analysis.

The role of MTHFR C677T polymorphism in repeated pregnancy loss (RPL) among different populations has been studied with inconsistent results. The study objective was to determine the association between MTHFR C677T polymorphisms and RPL among Arab women. The review included all the available studies investigating the association between MTHFR C677T polymorphism and RPL from 2000 until now. The searched database included Cochrane, Trip, EMBASE, and Google Scholar. Two authors independently reviewed the searched articles for eligibility, judged their risk of bias, and extracted the characteristics of the studies. Review Manager 5.3 program was used for data analysis using odds ratio (OR) at a 95% confidence interval (CI). The study revealed a statistically significant difference between cases and controls regarding combined MTHFR C677T polymorphisms (OR = 1.50, 95% CI = 1.15-1.96), MTHFR C677T heterozygous (OR = 1.41, 95% CI = 1.08-1.83), and MTHFR C677T homozygous (OR = 4.19, 95% CI = 1.87-9.39). Considerable significant heterogeneity was recorded in the three analyses (P < 0.05). The review supported the hypothesis that MTHFR C677T mutation is considered a significant risk factor for RPL among Arab women.

Post-COVID-19 syndrome: nature of symptoms and associated factors.

Aim: Post-COVID-19 syndrome is defined as continuous symptoms related to SARS-CoV-2 infection, which can persist for several weeks or months. Previous studies identified risk factors associated with post-COVID-19 syndrome, including female sex, hypertension, and allergic respiratory diseases. This study aims to investigate the frequency of this syndrome among Arabic patients. Subject and methods: A cross-sectional study was conducted from March to August 2022. The study included 520 Arabic patients with confirmed COVID-19 diagnosis, who were asked about possible symptoms persisting for ≥28 days. Results: Twenty-five percent (25%) of the included patients developed post-COVID-19 syndrome. The most common recorded symptoms were cough (32%), anosmia (32%), fatigue (28%), headache (19%), muscle pain (19%), and shortness of breath (17%). It was found that female sex, hospitalization due to initial COVID-19 infection, and the presence of chronic diseases were significant risk factors for developing post-COVID-19 syndrome. Conclusion: The study recorded post-COVID-19 syndrome among 25% of Arabic participants. Initial COVID-19 hospitalization, initial symptomatic COVID-19, and female sex were significant risk factors for developing post-COVID-19 syndrome.

COVID-19 vaccine acceptance: knowledge and beliefs.

Backgrounds: Vaccine acceptance varies across countries, generations, and the perceived personality of individuals. Investigating the knowledge, beliefs, and acceptability of COVID-19 vaccines among individuals is vital to ensuring adequate health system capacity and procedures and promoting the uptake of the vaccines. Results: A cross-sectional study was conducted from August 2021 to January 2022 in Saudi Arabia. The study included 281 residents to estimate their acceptance to receive COVID-19 vaccination. Around 70% of the included participants had a moderate to high COVID-19 vaccine acceptance rate during the data collection period. The risk increases to about two folds among undergraduates [OR 1.846 (1.034-3.296), p value = 0.036)] and increases to four folds among non-employed [OR 3.944 (2.310-6.737), p value = 0.001]. About 78% of participants with high and 44% with low COVID-19 vaccine acceptance (p value = 0.001) believed the vaccines were safe and effective. The belief that COVID-19 disease will be controlled within two years increased the risk for low vaccine acceptance by about two folds [OR 1.730 (1.035-2.891), p value = 0.035]. Good knowledge about COVID-19 vaccination significantly affected the acceptance rate (p value = 0.001). Conclusions: Several factors affect the intention of individuals to receive vaccines. Therefore, building good knowledge and health literacy through educational intervention programs, especially vaccine safety and effectiveness, is important for successful vaccination campaigns among the general population and ensuring control of the COVID-19 pandemic.

Protective Duration of ChAdOx1 and BNT162b2 Vaccines Against SARS-CoV-2 Infection.

BACKGROUND AND OBJECTIVE: A limited number of studies have addressed the protective duration of coronavirus disease 2019 (COVID-19) vaccines following primary and booster doses in Saudi Arabia. Therefore, this study aimed to evaluate the protective duration of primary and booster doses of BNT162b2 and ChAdOx1 COVID-19 vaccine batches in Saudi Arabia. METHODS: A cross-sectional study was conducted from 1 January to 31 December, 2021. The study included 53,354 people infected with severe acute respiratory syndrome coronavirus-2 2 weeks or more after receiving at least a primary vaccination of either the ChAdOx1 or BNT162b2 vaccine. RESULTS: The total median protective duration of both primary COVID-19 vaccinations was 134 days. Heterologous primary vaccination (ChAdOx1 followed by BNT162b2) showed a significantly higher median protective duration of 142 days. The results show that the total median protective duration of the first booster doses of COVID-19 vaccines was 57 days. ChAdOx1 batch code C1 was found to have the most extended protective duration of 173 days (range 163-192 days). CONCLUSIONS: The current study revealed that the median protective duration of ChAdOx1 and BNT162b2 COVID-19 primary vaccination regimens administered in Saudi Arabia in 2021 was 134 days and that heterologous primary vaccination (ChAdOx1→BNT162b2) exhibited a significantly higher protective duration than other vaccination regimens.

The role of telemedicine services in changing users' intentions for presenting to the emergency departments in Saudi Arabia.

Background: Emergency department (ED) overcrowding is described as one of the main issues in any hospital. In Saudi Arabia, the ministry of health applied new telemedicine technology to serve patients by using the mobile application, including the Sehha application and 937 medical call center. The main aim of this study is to determine the role of different telemedicine services in changing the intention users' intentions for visiting the emergency departments in Saudi Arabia. Methods: A cross-sectional study was conducted during August 2020 to May 2021 among 319 patients using two telemedicine services in Saudi Arabia, including the medical call center and Sehha smartphone application. The primary endpoint of this study was to determine the number of patients intended to visit ER before and after contacting one of the two telemedicine services and the frequency of people who changed their opinion to visit an ED. Results: This study analyzed the data from 319 patients who completed the survey provided by the Saudi Ministry of Health concerning information related to their health status and ED visits. Among patients that had the intention to visit the ED (N = 159), 53 of them did not go to EDs after using telemedicine services (p < 0.01). Regarding the medical call center and Sehha application, 9.6% and 24.4%, respectively, of the patients who used these telemedicine services changed their minds concerning visiting ED after taking the medical advice (p < 0.01). Conclusions: The implemented telemedicine services in Saudi Arabia, namely the Sehha application and medical call center, could reduce those intended to visit ED and consequently reduce the overload of EDs by providing medical advice to patients concerning their minor medical issues.

Adverse drug reactions from two COVID-19 vaccines reported in Saudi Arabia.

Background: Several reports have been published about the impact of coronavirus disease 2019 (COVID-19) vaccines on human health, and each vaccine has a different safety and efficacy profile. The aim of this study was to reveal the nature and classification of reported adverse drug reactions (ADRs) of the two COVID-19 vaccines (tozinameran and ChAdOx1) among citizens and residents living in Saudi Arabia, and show possible differences between the two vaccines and the differences between each batch on the health of populations. Methods: A cross-sectional study was conducted in Saudi Arabia between December 2020 and March 2021. Saudi citizens and residents aged ≥ 16 years who had at least one dose of any batch of either of the two approved COVID-19 vaccines (tozinameran and ChAdOx1) and who reported at least one ADR from the vaccines were included. The study excluded people who reported ADRs after receiving tozinameran or ChAdOx1 vaccines but no information was provided about the vaccine's batch number. Results: During the study period, 12,868 vaccinated people, including a high-risk group (i.e., those with chronic illness or pregnant women), reported COVID-19 vaccine ADRs that had been documented in the General Directorate of Medical Consultations, Saudi Ministry of Health. The study reported several ADRs associated with COVID-19 vaccines, with the most common (> 25%) being fever/chills, general pain/weakness, headache, and injection site reactions. Among healthy and high-risk people, the median onset of all reported ADRs for tozinameran and ChAdOx1 vaccine batches were 1.96 and 1.64 days, respectively (p < 0.01). Furthermore, significant differences (p < 0.05) were recorded between the two studied vaccines in regard to fever/chills, gastrointestinal symptoms, headache, general pain/weakness, and neurological symptoms, with higher incidence rates of these ADRs observed with the ChAdOx1 vaccine than the tozinameran vaccine. However, the tozinameran vaccine was found to cause significantly (p < 0.05) more palpitation, blood pressure variations, upper respiratory tract symptoms, lymph node swelling, and other unspecified ADRs than the ChAdOx1 vaccine. Among patients vaccinated with seven different batches of the tozinameran vaccine, people vaccinated with the T4 and T5 batches reported the most ADRs. Conclusion: There were significant differences regarding most of the reported ADRs and their onset among tozinameran and ChAdOx1 vaccines on both healthy people and high-risk individuals living in Saudi Arabia. Moreover, the study found that the frequencies of most listed ADRs were statistically different when seven batches of tozinameran vaccine were compared.

Impact of COVID-19 on the 937 Telephone Medical Consultation Service in Saudi Arabia.

The impact of COVID-19 on healthcare services has been profound. One major impact has been underutilization of traditional healthcare services by patients. In 2020, the Saudi Ministry of Health (MoH) started offering general COVID-19 enquiries, education, and medical and psychological consultations around the clock via their 937-Call Center. Given this major change, there was a need to understand the impact of the COVID-19 pandemic on Call Center services, specifically medical consultations, to suggest future recommendations for patient care optimization. This descriptive study analyzed routinely collected data on the 937-Call Center service between March 2020 and September 2020. Data were reviewed, coded, verified, and analyzed using SPSS v22. There was a 296% increase in the number of calls received by the 937-Call Center in 2020 compared to the same period in 2019. The majority of calls received in 2020 were general medical enquiries (98.41%), but about three million COVID-19-specific enquiries were also received in 2020. The increased number of calls was managed by accepting volunteers to handle calls: an average of 236 volunteers per month, handling about 20% of the total call volume. The majority of volunteers were physicians but with the presence of pharmacists, psychologists, and specialized healthcare workers such as nutritionists. Utilization of the 937-Call Center increased during the COVID-19 pandemic, suggesting that it has been an effective strategy for combatting the COVID-19 pandemic in Saudi Arabia. Further research is recommended to investigate the impact of COVID-19 on public awareness of the 937-Call Center and other health-related mobile apps.

Knowledge, beliefs, and acceptability of people toward new COVID-19 vaccines: a pilot study.

A cross-section pilot study was done to determine the knowledge and belief toward new COVID-19 vaccines among a small sample size group of people. A new Vaccine Acceptability Questionnaire (VAQ) consists of 31 questions that were concerned about three elements: underlying factors, knowledge, and beliefs. The study included 96 people from the different regions of Saudi Arabia who had accepted to participate in this pilot study. Around 31% of the included people had low to very low acceptability toward COVID-19 vaccines; however, the other 69% had moderate to high acceptability. The new simple designed questionnaire (VAQ) could be effective in assessing knowledge, beliefs, and acceptability toward COVID-19 vaccination among a specific group of population.

Onsite Versus Remote Working: The Impact on Satisfaction, Productivity, and Performance of Medical Call Center Workers.

Job satisfaction is determined as the measure to know the individuals' feelings toward their work. The working conditions that can affect satisfaction and performance of the call center agents have received particular concern. This study aimed to determine the role of remote call center working on agents' satisfaction compared to onsite workers. A cross-section study was conducted between December 2020 and April 2021 that include 124 agents working in a governmental medical call center in Saudi Arabia. Each agent was receiving a questionnaire that investigates his/her satisfaction with the job nature, supervisor support, job autonomy, job productivity, and performance. Seventy-seven physicians working onsite were compared to forty-seven physicians remotely working in the medical call center. The mean age of the physicians included was 43.17 ± 8.4 years, and most of them were male (>70%), married (>85%), and family medicine specialists (>50%). The mean years of experience in the medical field of the physicians included was 16.87 ± 8.07 years, and the mean years of experience in the medical call center was 1.44 ± .97 years. Onsite agents were more satisfied concerning job nature, supervisor support, productivity, and performance compared to remote agents (70.82 vs 53.47%, 63.38 vs 55.05%, and 66.51 vs 56.03%, respectively). However, onsite agents were less satisfied regarding job autonomy than remote physicians (46.81 vs 53.19%, P-value = .128). Overall, general satisfaction was more seen in physicians working onsite as opposed to remote workers in the medical call center in Saudi Arabia (64.90 vs 54.25%, P-value < .01).

Prevalence of Health Problems Targeted by the National School-Based Screening Program among Primary School Students in Saudi Arabia, 2019.

The Saudi Ministry of Health (MOH) established a National School-Based Screening Program (NSBSP) for health screening of schoolchildren. Students from specific grades were systematically screened for several health problems, including obesity, visual and auditory problems, dental cavities, scoliosis, and attention-deficit/hyperactivity disorder (ADHD). This cross-sectional study aimed to determine the prevalence of these health problems among primary school students based on secondary data obtained from the NSBSP. We included 444,259 screened school children from the first and fourth grades of 50% of the selected schools (both private and public) across the Kingdom of Saudi Arabia (KSA) during the academic year 2018-2019. Among them, the most prevalent health problems identified were dental cavities (38.7%), eye refractory errors (10.9%), and overweight and obesity (10.5%); the less prevalent problems included ADHD (2.81%), auditory problems (0.6%), and scoliosis (0.48%). A greater prevalence of most health problems was observed in girls more than boys. The NSBSP successfully aided the detection of health conditions with high and low prevalence among primary school students in the KSA, and thus, the identification of health problems of specific concern. Implementation of effective school health services for the prevention, early detection, diagnosis, and treatment of these health problems are imperative.
