Diabetes Various surveys over the last decade have shown that ten percent of Omani adults suffer from diabetes and a similar proportion has impaired glucose tolerance. A survey conducted in 1991 showed a diabetes prevalence of 8.3% based on fasting blood glucose. A more recent National Health Survey (2000), has shown diabetes to have increased significantly to 11.6%.

Metabolic syndrome (IDF criteria) Central obesity (waist circumference 94 cm for men and 80 cm for women), plus any 2 of the following 4 factors: Raised triglyceride (TG) levels 1.7 mmol/L, or specific treatment for this lipid abnormality Reduced high density lipoproteins (HDL) cholesterol: <1.03 mmol/L in men and <1.29 mmol/L in women, or specific treatment for these lipid abnormalities Raised systolic BP 130 or diastolic BP 85 mmHg, or treatment of previously diagnosed hypertension Raised fasting plasma glucose: FPG 5.6 mmol/L, or previously diagnosed type 2 diabetes
Prevalence of metabolic syndrome in Oman Females: 40.0% (95% CI 35.6% to 44.3%) Males: 18.4% (95% CI 14.5% to 22.3%) (p-value for the gender difference <0.001).
