Background: This study aimed to estimate the prevalence of prediabetes among Saudi adults and to evaluate their risk of developing cardiovascular diseases. Methods: This is a cohort of 2470 Saudi adults attending employee clinics in the university hospital. WHO-STEPs approach was used to collect sociodemographic (age, gender, and education), clinical (body mass index and blood pressure) and laboratory data (HbA1c, lipid profile and vitamin D concentration). Prediabetes was defined according to HbA1c level of 5.7-6.4%. Cardiovascular risk (CVR) scores were evaluated using the Framingham Risk Score. SPSS was used for data analysis to investigate the relation between different CVR and prediabetes. Results: Prediabetes affected 25.1% of the study population. Males had higher rates of prediabetes than females (27.5% versus 23.5%). The prevalence of prediabetes increased from 11.6% among young individuals (18-29 years) to 56.0% among participants 60 years and older. Prediabetes patients exhibited considerably higher levels of all cardiovascular risk factors and nearly half of them (49.3%) had at least two risk factors. The prevalence of intermediate CVR among prediabetics was 13.2% compared to just 2.9% among the normal group, and high CVR was defined in 3.7% among prediabetics compared to only 1.7% in the normal group. Having prediabetes increased the odds to develop higher CVR of 2.64 times compared to those without prediabetes (OR = 2.64, 95% CI = 1.51-4.64) and the level of vitamin D did not affect the odds of CVR. Conclusion: Prediabetes is quite prevalent among Saudi adults, and they are at a higher risk of cardiovascular diseases. Patients with prediabetes have higher cardiac risk scores when compared to normal participants across the whole spectrum of (25(OH)D) concentrations. Additionally, no significant correlation was observed between HbA1c and (25(OH)D) levels in prediabetics or normoglycemic subjects.

Objective This study aimed to estimate the risk of cardiovascular disease (CVD) among patients with and without diabetes mellitus (DM) using the Framingham risk score (FRS) and to investigate the effect of DM control on CVD risk. Methodology A total of 2432 participants who had their glycosylated hemoglobin (HbA1c) measured within the last three months were included in this study. The study cohort was divided into three categories: non-diabetic, participants with controlled DM (HbA1c<7%), and uncontrolled DM (HbA1c≥7%). The World Health Organization’s stepwise approach to chronic disease risk factor Surveillance-Instrument v2.1 was used in this study to collect the anthropometric and biochemical measurements. The Framingham Coronary Heart Risk Score (FRS) was used to calculate the 10-year cardiovascular risk (CVR). The groups were compared concerning the prevalence of metabolic, socioeconomic, and cardiac risks. Results Out of 2432 participants, 149 had controlled DM (6.1%), 286 had uncontrolled DM (11.8%), and 1997 participants were normoglycemic (82.1%). Compared to healthy participants, diabetic participants showed more high-risk characteristics across all CVR parameters. Uncontrolled diabetic patients had a graver laboratory and clinical profiles compared to the controlled DM group. As measured by FRS, nearly half of patients with controlled DM (49.9%) and two-thirds of patients with uncontrolled DM (63.3%) were classified as intermediate and high-risk compared to 4.6% of the healthy participants. Compared to healthy participants, patients with controlled DM showed a threefold increased CVR (OR = 3.02, 95% C.I. = 1.41–7.24) while this risk catapulted to 13 times among those with uncontrolled DM (OR = 13.57, 95% C.I. = 6.99–26.36). Conclusion Participants with DM are at moderate to high CVR. Individuals with uncontrolled DM showed higher CVR profiles as measured by FRS and have a higher prevalence of obesity, unhealthy diet, and physical inactivity.
