In this longitudinal study focusing on abdominal fat among men aged 40-49 years(Japanese men in Japan and Caucasian men in US), we quantified areas of subcutaneous adipose tissue(SAT), and visceral adipose tissue(VAT), using computed tomography scan. We then studied how change in SAT/VAT was correlated with changes in cardiovascular risk factors. Change in VAT among Japanese men was generally more correlated with changes in glucose, blood pressure, and triglycerides, compared to Caucasian men in US. This(indirectly) suggests that influence of VAT on incidence metabolic risk factors and/or metabolic syndrome may be stronger in Japanese men than in Caucasian men.
