The association of the visceral adiposity index with insulin resistance and beta-cell function in Korean adults with and without type 2 diabetes mellitus

초록

This study was conducted to assess the association of the visceral adiposity index (VAI) with insulin resistance and beta cell function in Korean adults with and without type 2 diabetes mellitus. The study was carried out using data from the 2015 Korean National Health and Nutrition Examination Survey (KNHANES VI-3) and included 4,922 adults, aged 20 or older. There were several key findings in the present study. First, in subjects without type 2 diabetes mellitus, homeostasis model assessment of insulin resistance (HOMA-IR) (p < 0.001) and beta cell function (HOMA-B) (p < 0.001), insulin (p < 0.001), fasting blood glucose (FBG) (p < 0.001), and metabolic syndrome (MetS) score (p < 0.001) were positively associated with quartiles of VAI. Second, in subjects with type 2 diabetes mellitus, HOMA-IR (p = 0.038), FBG (p = 0.007), and MetS score (p < 0.001) were positively associated with quartiles of VAI, but associations with HOMA-B (p = 0.879) and insulin (p = 0.104) were not significant. In conclusions, the visceral adiposity index is positively associated with insulin resistance and beta cell function in Korean adults without type 2 diabetes mellitus. The visceral adiposity index is positively associated with insulin resistance but not beta cell function in Korean adults with type 2 diabetes mellitus.
