  1. Odds ratios were obtained by multivariate logistic regression analysis with backward selection. The variables that entered into the model at first step were age, sex, education level (Illiterate/primary, secondary, diploma/higher), family history of diabetes, hypertension (blood pressure ≥ 140/90 mm/Hg and/or taking of antihypertensive medication), obesity (BMI<25, 25–29.9 and ≥ 30 kg/m2 with <25 as reference group), Abdominal obesity (waist circumference>88 or >102 cm in females and males respectively), glucose tolerance categories, high triglyceride (>2.2 mmol/l) and low HDL cholesterol (<1.0 or <1.3 mmol/l in males and females respectively). BMI categories and abdominal obesity were fitted separately into the models.
