[Show abstract][Hide abstract] ABSTRACT: The relationship between visceral adiposity and the incidence of functional dyspepsia (FD) has not yet been studied. The purpose of the present study is to evaluate the association between visceral adiposity and the risk of FD.
This is a case-control study that compares the abdominal adipose tissue area between subjects with FD and control subjects without FD, who underwent abdomen computerized tomography (CT) for health examinations in a tertiary center. Retrospectively, a telephone survey was conducted to diagnose FD using the Rome III criteria. We measured various indices of obesity including body mass index (BMI), waist circumference (WC), visceral adipose tissue (VAT) area, subcutaneous adipose tissue (SAT) area and the VAT/SAT ratio in order to evaluate the association between FD and abdominal adiposity.
A total of 363 subjects were included in the present study. FD was diagnosed in 90 subjects (24.8%). In the univariate analysis, WC, VAT area, TAT area, VAT/SAT ratio and the presence of erosive esophagitis were significantly higher in the FD group than in the non-FD group. In the multivariate analysis, a higher VAT area (odds ratio (OR), 3.76; 95% confidence interval (CI), 1.24-11.40; highest quartile vs. lowest quartile, p = 0.019) and VAT/SAT ratio (OR, 2.35; 95% CI, 1.27-4.32; highest quartile vs. lowest quartile, p = 0.006) were independently associated with a risk of FD.
Visceral adiposity as measured by the VAT area and VAT/SAT ratio is associated with an increased risk of FD. This article is protected by copyright. All rights reserved.

[Show abstract][Hide abstract] ABSTRACT: The obese patients with diabetes or cardiovascular risk factors are associated with increased risk of colorectal cancer as well as adenomas under the shared pathogenesis related to atherosclerosis. Here we determined the association between increased arterial stiffness and colorectal adenomas incorporating parameters including age, gender, waist circumference, body mass index, lipid profiles, fasting glucose, and blood pressure. Subjects who simultaneously underwent colonoscopies and pulse wave velocity (PWV) determinations between July 2005 and September 2006 were analyzed, based on which the subjects were classified into two groups as patients group with colorectal adenomas (n = 49) and control group (n = 200) with normal, non-polypoid benign lesions or hyperplastic polyps. Uni- and multi-variate analyses were performed to calculate the odd ratio for colon adenomas. Based on uni-variate analysis, age, waist circumference, body mass index, heart-femoral PWV (hfPWV), and brachial-ankle PWV were significantly associated with adenomas (p<0.05) and multiple logistic regression analysis showed that the heart-femoral PWV, waist circumference, and the levels of LDL-C were significant risk factor for colorectal adenoma. However, arterial stiffness did not affect the progression of colon adenoma. The finding that hfPWV, reflecting aortic stiffness, was increased in patients with colorectal adenomas lead to conclusion that patients who have prominently increased arterial stiffness can be recommended to undergo colonoscopic examinations and at the same time we also recommend counseling about the risk for atherosclerosis in those who have colorectal adenomas.
