【Abstract】:ObjectiveTo investigate the risk factors and insulin resistance (IR) of nonalcoholic fatty liver disease (NAFLD) with a normal visceral adipose tissue (VAT) area. MethodsA total of 45 NAFLD persons with a normal VAT area who were admitted to Quanzhou First Hospital Affiliated to Fujian Medical University from June 2017 to May 2018 were enrolled as observation group, and 27 non-NAFLD patients with a normal VAT area were enrolled as control group. VAT area, waist circumference, fasting blood glucose (FBG), and fasting insulin (FINS) were measured for both groups, homeostasis model assessment of insulin resistance (HOMA-IR) was calculated, and the correlation of IR with the indices including waist circumference was analyzed. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. Pearson correlation analysis and Spearman correlation analysis were used to investigate the correlation of normally and non-normally distributed continuous data. A forward logistic regression analysis was used to identify related risk factors. ResultsThe NAFLD group had a significantly higher level of IR than the control group, and there was a significant difference in HOMA-IR between the two groups (2.66(1.59-4.06) vs 1.84(125-2.47), Z=364.000, P=0005). IR was positively correlated with FBG (r=0.412, P=0.005), FINS (r=0.789, P<0001), and TG (r=0.306, P=0041). IR was negatively correlated with HDL(r=-9398,P=0007). The multivariate regression analysis showed that waist circumference was an independent risk factor for NAFLD with a normal VAT area (regression coefficient = 0.181, odds ratio = 1.198, 95% confidence interval: 1.099-1.306, P<0.001). ConclusionThere is a certain degree of IR in NAFLD patients with a normal VAT, and waist circumference is an independent risk for NAFLD with a normal VAT.
