Author and year	Methods to assess metabolic syndrome
Farha and Alefishat 2018 (5)	AHA/NHLBI: presence of at least three of the following conditions: FBG ≥100 mg/dL or on drug treatment for elevated glucose; blood pressure ≥130/85 mmHg or on antihypertensive drug treatment in a patient with a history of hypertension; TGs ≥150 mg/dL or on drug treatment for elevated TGs; HDL-C <40 mg/dL in men or <50 mg/dL in women or on drug treatment for reduced HDL-C; or waist circumference ≥102 cm in men or ≥ 88 cm in women.
Pietroiusti et al. 2010 (20)	NCEP: presence of at least three of the following conditions: waist >102 cm in men and >88 cm in women, serum triglycerides >1.695 mmol/l (150 mg/dl), HDL-cholesterol 1.036 mmol/l (40 mg/dl) in men and,1.295 mmol/l (50 mg/dl) in women, blood pressure >130 or >85 mmHg or treatment for hypertension, and plasma glucose >5.6 mmol/l (100 mg/dl)
Korsiak et al. 2017 (10)	2009 JISCS: presence of at least three of the following conditions: high waist circumference (≥80 cm); elevated triglycerides (≥1.7 mmol/L); reduced high-density lipoprotein (<1.3 mmol/L); elevated blood pressure (systolic ≥130 and/or diastolic ≥85 mm Hg); elevated fasting blood glucose (≥100 mg/dL).
Lajoie et al. 2015 (11)	According to the above mentioned “2009 JISCS”
