Objective: To examine the incidences of metabolic risk factors according to changes in visceral fat area (VFA) in a large Japanese population.
Design and methods: The subjects were 973 men who received a computed tomography (CT) examination in health checkups twice (2004-2005 and 2007-2008), and not having two or more of metabolic risk factors (except for the waist circumference) in 2004-2005. VFA was measured using CT. To assess the potential influence of changes in VFA for the 3-year incidences of each metabolic risk factor and clustering metabolic risk factors, logistic regression analyses were used.
Results: A significant association was observed between the change in VFA and the components of the metabolic risk factors. Incidences of the components of the metabolic risk factors were significantly higher among subjects with a larger increase in VFA and were significantly lower among subjects with a larger decrease in VFA (trend P < 0.001). Significant increases in the odds ratios for the incidences of high triglycerides and low high-density lipoprotein cholesterol level were observed among subjects with ≥50 cm(2) VFA increase.
Conclusions: The adoption of a lifestyle that does not increase the VFA is important for preventing metabolic syndrome.
