Japanese men aged 36-79 years undergoing a general health check.Methods: We investigated the associations between atherosclerosis/arterial stiffness, evaluated by means of CIMT and CAVI, and diabetes for all subjects, who were divided 10 into tertiles according to TG-HDL levels. Diabetes was defined as HbA 1c (NGSP) â„6.5 %, and/or initiation of glucose-lowering medication or insulin therapy.Results: Of the130 diabetes patients identified in the cohort, 56 patients had high TG-HDL (high TG-HDL diabetes) and 43 had low TG-HDL (low TG-HDL diabetes).We found that only diabetic patients with high TG-HDL were at a significant risk for 15 atherosclerosis (diagnosed as CIMTâ„1.1 mm) and increased arterial stiffness (diagnosed as CAVI â„8.0). The multivariable-adjusted odds ratios and 95 % confidence intervals of atherosclerosis and increased arterial stiffness for diabetes were 2.67 (95%CI:1.35-5.28) and 2.36 (95%CI:1.01-5.50), for total TG-HDL diabetes 2.57(95%CI:1.32-5.02) and 3.56(95%CI: 1.50-8.46) for high TG-HDL diabetes, and 1.17(95%CI:0.52-2.63) and 0.80(95%CI:0.33-1.90) for low TG-HDL diabetes, respectively.
