T1955 Presence of Hiatal Hernia (HH)Is Not Related to Obesity and Increasing Age

calculated from cross-sectional CT images. Results: The prevalence for MS was 27% in the cases and 19% in the controls (p <0.001). Multivariate logistic regression analysis demonstrated that MS is associated with RE (OR = 1.42, 95% CI: 1.26-1.60, p <0.001). Among the individual components of MS, WC (OR = 1.47, 95% CI: 1.30-1.65, p <0.001) and elevated triglyceride (OR = 1.20, 95% CI: 1.05-1.36, p = 0.006) independently increased the risk for RE. Cases showed higher mean VAT (136.1 ± 57.8 vs. 124.0 ± 54.7, p <0.001) and SAT (145.9 ± 56.8 vs. 133.5 ± 50.7, p <0.001). However, only VAT was an independent risk factor for RE after adjusting for multiple confounders (OR for the highest quartile of VAT =1 .61, 95% CI: 1.10-2.36, p=0 . 014). Conclusions: MS was associated with RE. Abdominal obesity, especially visceral obesity was an important risk factor for RE.
