Background: Previous research has linked high coffee consumption to an increased risk of metabolic syndrome (MetS). This study aimed to assess the relationship between coffee consumption and MetS components among Saudi adults. Methods: A cross-sectional study was performed on adults who met at least three criteria for a MetS diagnosis. Data concerning demographics, lifestyle, sleeping patterns, medical health, anthropometric measurements, habitual coffee drinking, and lab levels for HDL-C, LDL-C, TC, TGs, HbA1c, and FBG were collected. Results: Of the 95 participants, 51% were women, 75.8% were >50 years old, 75.8% were obese, 62% were used to practicing physical activity, 74.5% never smoked, 56.4% slept < 7 h/day, and 89.5% were coffee consumers. Of these, 94.7% had high waist circumference, 63.2% had high BP, 47.4% had high FBG, 41.1% had low HDL, and 23.2% had high TGs. For coffee consumers, 37.6% drank a small cup, 34.5% drank coffee once daily, 89.4% drank Arabic coffee, and 75.3% added no additives. Conclusions: No significant association was found between coffee consumption patterns and any MetS component, with the exception of elevated TGs, which was strongly associated with coffee cup size and number of daily cups. Waist circumference and BMI had a strong positive correlation with coffee cup size, and there was a significant relationship between the number of daily cups, BMI, and TC. Further prospective studies are needed to establish a causal relationship.

Purpose: 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.Design/methodology/approach: 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.Findings: This study showed that vitamin D level had a significant association with the overall performance of the students as well as their self-efficacy.Research limitations/implications: 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.Social implications: 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.Originality/value: 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.

Metabolic syndrome (MetS) is a multifactorial condition characterized by central obesity, hypertension, dyslipidaemia, and hyperglycaemia, predisposing individuals to cardiovascular disease and type 2 diabetes. This cross-sectional study investigated the relationship between dietary intake, sociodemographic factors, and components of MetS among Saudi adults aged 30 years and older attending King Abdulaziz University Hospital. Fifty-three participants meeting MetS diagnostic criteria were assessed through anthropometric measurements, biochemical markers, and two-day dietary recalls analyzed using MyFood24 software. Descriptive and correlation analyses were conducted using SPSS 26.0. The majority of participants (73.6%) were aged over 50 years, were obese (75.5%), and exhibited a high waist circumference (94.3%). Low fibre (6.6 g/day) and high fat (41.8 g/day) intake patterns were evident. Salt intake showed a significant inverse correlation with systolic blood pressure (ρ = −0.36, p < 0.01), potentially reflecting under-reporting or dietary adjustments following diagnosis. Higher BMI correlated positively with waist circumference and diastolic pressure, while frequent physical activity correlated negatively with these parameters. These findings emphasize the influence of diet and lifestyle on metabolic risk and underscore the need for culturally tailored interventions promoting balanced macronutrient intake, increased fibre consumption, and enhanced physical activity to mitigate MetS prevalence among Saudi adults.
