Dental caries is a preventable childhood disease, but public health efforts are hampered due to limited information on associated factors in vulnerable populations. Our study was aimed at estimating the prevalence of dental caries and identifying key associated factors in four major risk domains, including socioeconomic factors, child oral health behavior and practices, child feeding practices, and dietary habits among primary school children in Saudi Arabia. A cross-sectional study design was used to recruit 578 male Saudi primary school children, aged 6–8 years, from 12 primary schools in five different regions of Riyadh. Children were clinically screened to detect carious lesions in primary teeth according to World Health Organization’s criteria. Structured self-administered questionnaire was used to collect information on social and individual factors from the parents. The odds ratios and 95% confidence intervals of associated factors for dental caries were computed using logistic regression models; key factors were identified by systematic selection process that accounted for multicollinearity and bias correction. Dental caries was prevalent among children (83%, 95% confidence interval 79.7–86.0%). Individual factors, including irregular brushing, late adoption of brushing habit, consulting dentist for symptomatic treatment, lack of breast feeding, sleeping with a bottle in mouth, habit of snacking between meals, low consumption of fruits, and frequent consumption of soft drinks and flavored milk, were predominantly associated with dental caries in children, instead of socioeconomic factors (p < 0.05, adjusted R-square 80%). Dental caries were prevalent in school children, and individual factors were predominantly associated with the disease.

Hypertension and prehypertension pose significant public-health and clinical challenges for both economically developed and developing nations. Prevalence of these conditions are frequently underreported because of its often-silent nature. Population-based studies that explore the occurrence and correlates of these conditions are scarce in Saudi Arabia. This study aimed at estimating the prevalence and associated factors of hypertension and prehypertension on a representative sample of males and females living in Al-Kharj town in Saudi Arabia. Cross-sectional analysis was performed from January 2016 until June 2016 by recruiting a representative sample (n = 1019; aged 18 to 67 years) of the Al Kharj population. All participants completed a self-administered questionnaire, followed by a physical examination and blood test. Statistical analysis was carried out using SPSS version 24.0 for Windows. The prevalence of prehypertension was 66.1, 48.1 and 54.9% in male, female and all subjects, respectively. The prevalence of hypertension was 6.0, 4.2 and 4.9% in male, female and all subjects, respectively. Being overweight was associated with the highest risk of hypertension (OR = 4.98 [95% C.I. = 1.98–12.52], P = 0.001). People who were classified as class I obese had 3.5 times the risk of hypertension compared with the non-obese group (OR = 3.49 [95% C.I. = 1.42–8.63], P = 0.007). Risk of pre-hypertension was significantly lower in females (OR = 0.48 [95% C.I. = 0.32–0.71]) and tends to increase with obesity status. Gender-specific analyses found that males in the lowest education attainment level had a significantly increased risk of pre-hypertension (OR = 6.56 [95% C.I. = 1.27–33.85], P = 0.003). This population-based study in Saudi Arabia shows that hypertension and prehypertension are common conditions particularly among males. Overweight and obesity was associated with both conditions. In addition, lower education attainment was a significantly associated factor among males. Future prospective studies are needed to confirm the etiological nature of such associations.

Introduction: Low back pain (LBP) is a major health problem with significant public health and economic burden. Few studies have clarified the role of psychosocial factors in LBP occurrence. In this study, we assessed psychosocial and occupational factors associated with LBP, within the last 12 months, among nurses in Saudi Arabia. Methods: A cross-sectional study was conducted in 16 hospitals across Riyadh, Saudi Arabia. A sample of 427 nurses was surveyed. The anonymous questionnaire contained valid and reliable questions assessing LBP, as pain between the costal margins of the 12th rib and the gluteal folds, and questions related to psychosocial and work-related factors experienced by the nurses. Descriptive statistics were reported for all variables. Univariate and multivariate logistic regression analyses assessed the likelihood of significant associations between study variables and LBP. Results: The prevalence of reported LBP was 80%. Factors associated with LBP in univariate analysis were frequent lifting (OR = 2.32; 95%CI: 1.34-4.01), work-related stress (OR = 5.81; 95%CI: 3,37-9,62), lack of job satisfaction (OR = 2.08; 95%CI: 1.13-3.85), work-related problems (OR = 2.40; 95%CI: 1.44-4.02), and financial problems (OR = 2.08; 95%CI: 1.26-3.38), while factors that remained significantly associated with LBP in the final multivariate analyses were frequent lifting (OR = 2.04; 95%CI:1.09-3.81), work-related stress (OR = 4.22; 95%CI: 2.34-7.48), and lack of job satisfaction (OR = 1.87; 95%CI: 1.24-3.58). Conclusion: The prevalence of LBP is high in this sector of the health-care workforce. Ergonomic and psychosocial factors may be considered contributing factors for low back pain. Special attention to stress-reduction, counseling, and policies to improve job satisfaction are recommended in order reduce LBP and improve the health and safety of nurses in Saudi Arabia.

Background: Colorectal cancer (CRC) is a major health problem. It is the third most diagnosed common tumour and the fourth leading cause of cancer-related deaths worldwide. Early screening has been shown to decrease the incidence of CRC cancer and decrease mortality. In Saudi Arabia (SA), there is no national policy for CRC screening despite the growing incidence of the disease. This study investigated the knowledge of risk factors for CRC, recommendations for screening, and attitudes and barriers towards screening among medical students. Methods: Data was collected using a self-administered valid and reliable questionnaire consisting of demographic characteristics, knowledge, attitude, and barriers measurements completed by 581 medical students from two Saudi schools. Frequencies and mean scores of knowledge and attitude were determined. The likelihood of students having adequate knowledge of CRC risk factors and screening modalities was estimated using multivariate logistic regression analysis. Results: Knowledge of the risk factors for CRC and screening modalities, and attitude towards screening were poor in 52.47 and 57.83% of the surveyed medical students; respectively. Higher level of medical education (OR = 3.23; 95% CI: 2.01–5.18) and a positive attitude towards CRC screening (OR = 2.74; 95% CI: 1.86–4.03) were independent predictors of higher knowledge levels. Lack of awareness about CRC and screening modalities among patients, and shortage of specialized healthcare providers were barriers independently associated with low knowledge levels. Conclusions: Saudi medical students have limited knowledge of CRC risk factors of and a poor attitude towards CRC screening. These results contribute to our understanding of missed teaching opportunities in Saudi medical schools and suggest intervening at the medical school, clinical practice, and population levels to increase CRC screening practices.

Background: Childhood obesity is a global public health concern with major consequences. In Saudi Arabia, the percentage of children who are overweight or obese has significantly increased in the past two decades, raising concerns about the physical and psychosocial consequences of this burden. This study aimed at investigating the different risk factors contributing to childhood obesity in Saudi Arabia.Methods: A case-control study was conducted among 492 school children (246 overweight/obese children, and 246 normal weight control children aged 5-9 years). Using valid and reliable instruments, parental and child characteristics, behavioral practices, screen use, and other activities were assessed as risk factors for childhood obesity using logistic regression analysis.Results: An unemployed father (OR=11.90; 95% CI: 7.47-18.93), a father with overweight/obesity (OR=2.04; 95% CI: 1.40-2.96), an incorrect parental perception of child’s weight status (OR=2.54; 95% CI: 1.75-3.68), cesarean delivery (OR=2.52; 95% CI: 1.56-4.09), daily time in active play for less than 30 min (OR=2.18; 95% CI: 1.44-3.28), frequent snacking (OR=1.74; 95% CI: 1.05-2.93), and screen time use for more than 2 h per day outside of school (OR=1.62; 95% CI: 1.12-2.34) were all independent risk factors for being overweight or obese among the selected cases.Conclusion: Efforts to prevent childhood overweight and obesity in this population should focus primarily on the early identification and confrontation of risk factors. Such risk factors include parental characteristics and awareness of the magnitude of the burden obesity poses, behavioral practices such as frequent snacking, screen time use, and physical activity.

Well-being is an essential measure that contributes to the evaluation of the health and quality of life of populations. In 1948, the World Health Organization (WHO) defined health as physical, mental and social well-being. A cross-sectional survey was conducted in Riyadh, Saudi Arabia, between July and September 2015. Women aged 18 years old and above were invited to participate in the study. The data were collected using the WHO’s Well-Being Index questionnaire. Univariate and multivariate logistic regression models were fitted to identify factors that are significantly associated with well-being. A total of 900 women completed the survey. Approximately 58% of the women reported moderate to high (≥50) score of well-being, whereas 41.7% reported ill-being/likely depression. Experiencing violence, living in unfavorable physical conditions and reporting morbidities were shown to be significantly associated with low levels of subjective well-being (ill-being) (p < 0.0001). Our study revealed a significant percentage of low levels of well-being among women in Riyadh, Saudi Arabia, and identified the factors associated with them. Further research in this domain is recommended to better investigate additional causes of the low levels of well-being hence help in planning and guiding necessary interventions.
