AGMbfasting glucose levels ≥100 mg/dl (≥5.6 mmol/l) or previously diagnosed type 2 diabetesfasting glucose levels ≥100 mg/dl (≥5.6 mmol/l) or previously diagnosed type 2 diabetesfasting glucose levels ≥100 mg/dl (≥5.6 mmol/l) or drug treatment for elevated glucose

Abbreviations: AO, abdominal obesity; AGM, abnormal glucose metabolism; WC, waist circumference; TG, tryglicerides; HDL-C

high-density lipoprotein cholesterol; BP, blood pressure.

  • aBased on a joint interim statement of the International Diabetes Federation Task Force on Epidemiology and Prevention; National Heart, Lung, and Blood Institute; American Heart Association; World Heart Federation; International Atherosclerosis Society; and International Association for the Study of Obesity.

  • bIn this analysis, HbA1c 5.7% or more was used instead of fasting glucose for defining abnormal glucose metabolism, according to the American Diabetes Association recommendations (2010).
