Background: Saudi Arabia is a community thrilled by sudden social and economical changes, leading to a sharp increase in the prevalence of abnormal glucose metabolism. Age-specific diabetes and impaired fasting glucose prevalence is the focus of this study with the expected risk factors. Methods: A nationwide, household, randomized, population based cohort of 18 034 participants aged ≥30 years was selected to test for abnormal glucose metabolism using fasting plasma glucose (FPG) according to American Diabetes Association (ADA) criteria. Results: The prevalence of diabetes was 25.4% with 40.3% being unaware of their disease, while impaired fasting glucose (IFG) affected 25.5% of the total sample. IFG to diabetes ratio was one in this study, decreasing with age and increasing with body weight. Age ≥45 years, hypertension, history of gestational diabetes mellitus (GDM), and high triglycerides are the strongest risk factors in diabetic patients, while history of GDM, dyslipidemia, obesity, and high triglycerides are the most significant risk factors in IFG participants. Conclusions: Abnormal glucose metabolism has reached an epidemic level in this society, where half of adults and older are affected. Risk factors are behind this epidemic and the quick shift from IFG to diabetes in this society.

BACKGROUND AND OBJECTIVESSaudi Arabia underwent opulence-driven socio-cultural and lifestyle changes leading to soaring rates of diabetes mellitus. This study exposes the epidemiology of abnormal glucose metabolism namely: diabetes and impaired fasting glucose (IFG) in 13 administrative regions of Saudi Arabia.DESIGN AND SETTINGSThis is a nationwide, household, population-based cross-sectional study that was conducted through primary health care centers during the period 2007–2009.PATIENTS AND METHODSA nationwide, household, population-based cohort of 53 370 participants aged 0–100 years adjusted to be compatible with population census was interviewed and anthropometric measures were collected. Fasting blood sample was used to screen for IFG and diabetes.RESULTSThe overall prevalence of abnormal glucose metabolism was 34.5%, which included 22.6% patients with IFG, 11.9% patients with diabetes, and 6.2% patients who unaware of their disease. Diabetes prevalence was 40.2% for subjects aged ≥45 years and 25.4% for those aged ≥30 years that decreased to 11.9% when the full age spectrum was considered. Type 1 diabetes prevalence was 0. 8%, contributing only to 6.6% of the total population of patients with diabetes. The top 5 regions with the highest abnormal glucose metabolism prevalence were Makkah (43.4%), Aljouf (41.7%), Eastern region (37.16%), Madinah (35.4%), and Qassim (33.7%). Urbanization, age, and obesity were behind the wide variations in diabetes and IFG prevalence in the 13 regions.CONCLUSIONAbnormal glucose metabolism has reached an epidemic state in Saudi Arabia, where one-third of the population is affected and half of diabetic cases were unaware of their disease. This observation warrants an urgent strategy for launching diabetes primary prevention and screening programs.

Objectives:To assess health care services provided to type 1 and type 2 diabetic patients and diabetes health care expenditure in the Kingdom of Saudi Arabia (KSA).Methods:This study was part of a nationwide, household, population based cross-sectional survey conducted at the University Diabetes Center, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia between January 2007 and December 2009 covering 13 administrative regions of the Kingdom. Using patients’ interview questionnaires, health care services data were collected by trained staff.Results:A total of 5,983 diabetic patients were chosen to assess health care services and expenditure. Approximately 92.2% of health services were governmental and the remaining 7.8% were in private services. The mean annual number of visits to physicians was 6.5±3.9 and laboratories was 5.1±3.9. Diabetic patients required one admission every 3 years with a mean admission duration of 13.3±28.3 days. General practitioners managed 85.9% of diabetic cases alone, or shared with internists and/or endocrinologists. Health care expenditure was governmental in 90% of cases, while it was personal in 7.7% or based on insurance payment in 2.3%.Conclusion:Health services and its expenditure provided to diabetic citizens in Saudi Arabia are mainly governmental. Empowerment of the role of both the private sector and health insurance system is badly needed, aside from implementing proper management guidelines to deliver good services at different levels.

Sex hormone binding globulin (SHBG) is demonstrated to be decreased in subjects with metabolic syndrome (MetS). The aim of the present study was to investigate the association of SHBG in relation to MetS components among men with type 2 diabetes (T2D). This cross-sectional study was carried out among 429 Saudi T2D male patients aged >30 years. Metabolic syndrome was defined using International Diabetes Federation (IDF) criteria. Fasting blood glucose (FBG), HbA1c, albumin, and lipid parameter were measured. Gonadal hormones, namely total testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and SHBG were determined using ELISA. The SHBG levels of the MetS group was significantly lower than non-MetS group 47.25±31.03 nmol/l vs. 56.55±37.84 nmol/l; p=0.013. As the MetS score increases, SHBG and HDL levels decrease while weight, BMI, waist circumference, SBP, DBP, FBG, HbA1c, TC, and TG levels increase. SHBG correlated with age, BMI, TG, HDL, TT, free testosterone, and bio-available testosterone. This is the first study that provides detailed analyses of SHBG with MetS components in male diabetic subjects. The mean serum SHBG levels gradually declined with the addition of MetS components in T2D men. TT, free testosterone, and bio-available testosterone remained independently associated with SHBG by multivariable regression analysis.
