Increased visceral fat and impaired glucose tolerance predict the increased risk of metabolic syndrome in Japanese middle-aged men.
Impaired glucose tolerance (IGT) represents a stage of pre-diabetes and is a risk factor for future cardiovascular disease (CVD) which is a major cause of death in type 2 diabetes. The metabolic risk factors such as elevated blood pressure (elevated BP), abdominal obesity, dyslipidemia (elevated levels of total triglycerides [TG] and low levels of HDL cholesterol), and hyperglycemia precede the onset of the metabolic syndrome that increases the risk for CVD. This clustering is commonly associated with pre-diabetic hyperinsulinemia and it reflects peripheral insulin resistance. The present study documented that a visceral fat area (VFA) >/= 100 cm (2) can replace waist-to-hip ratios (WHR) associated with IGT or IFG/IGT as a critical risk for the development of the metabolic syndrome in Japanese middle-aged men. ⋯ VFA >/= 100 cm (2) strongly correlates with prediabetic IGT or IFG/IGT which is possibly associated with underlying insulin resistance, and is a critical risk factor linked to the development of metabolic syndrome in Japanese middle-aged subjects with IGT or IFG/IGT.
