Abstract/OtherAbstract:
Postprandial metabolic dysregulation plays a role in the development of atherosclerosis. Visceral fat accumulation is an important component of various metabolic disorders including glucose intolerance, dyslipidemia, and hypertension, which correlate with atherosclerotic cardiovascular disease. The aim of the present study was to compare the postprandial response of various metabolic parameters, blood pressure, adiponectin, and oxidative stress to 75-g oral glucose tolerance test (OGTT) in men with (n = 23) and without (n = 7) abdominal obesity based on waist circumference (WC) cutoff value of 85 cm (based on the Japanese criteria for the metabolic syndrome). The cross-sectional prospective study included 30 male subjects who were on no medications and newly diagnosed with mild hypertension and/or dyslipidemia. The percentage change in each parameter ([each parameter at 120 minutes after an OGTT - that before an OGTT]/that before an OGTT x 100) was calculated. The percentage systolic blood pressure, percentage diastolic blood pressure, and percentage triglyceride were -6.3% +/- 3.5%, -9.4% +/- 3.0%, and -10.2% +/- 2.1%, respectively, in the WC less than 85 group (vs baseline: P = .10, P < .01, and P < .001) and 2.0% +/- 1.7%, 0.9% +/- 2.4%, and 2.8% +/- 3.3%, respectively, in the WC at least 85 group (vs WC <85 group: P < .05, each). However, there were no significant differences in percentage total cholesterol and percentage high-density lipoprotein cholesterol between the 2 groups. The percentage thiobarbituric acid-reacting substances tended to be lower in the WC less than 85 group (vs baseline: P = .07), but not in the WC at least 85 group, albeit statistically insignificant (WC <85 vs >/=85 group: P = .057). The maximum carotid intima-media thickness was larger in the WC at least 85 group than the WC less than 85 group (P < .05). Evaluation of postprandial changes in obesity-related parameters may be important in preventing atherosclerotic diseases.
