Abstract

AbstractBackgroundDiabesity is a term used to emphasize the dual epidemic and the combined detrimental effects of diabetes and obesity. We aimed to investigate the associations of diabesity with the incidence and resolution of nonalcoholic fatty liver disease (NAFLD).MethodsThis prospective cohort study included 5549 participants with a median follow‐up of 4.3 years (2010–2015). Diabesity was defined as six categories by the combinations of glucose tolerance status (normal glucose tolerance [NGT], prediabetes, and diabetes) diagnosed by fasting and oral glucose tolerance test 2‐h glucose and hemoglobin A1c and general or abdominal obesity status. We examined the odds ratios (ORs) for the incidence and resolution of NAFLD associated with diabesity categories, respectively.ResultsFor NAFLD incidence, compared with the diabesity category of NGT with nonobesity, the categories of either glucose intolerance or general obesity were associated with higher risks of NAFLD, of which the categories with obesity, regardless of glucose intolerance status, exhibited greater risks (ORs ranged from 3.19 to 4.49) than the categories of nonobesity. For NAFLD resolution, the categories of prediabetes or diabetes with obesity were associated with decreased likelihoods of a resolution of NAFLD (ORs ranged from 0.40 to 0.58). These association patterns were consistent across various definitions of diabesity by glucose tolerance status diagnosed by different combinations of glycemic parameters and general or abdominal obesity.ConclusionsThe diabesity association pattern with NAFLD incidence was mainly determined by obesity, while that with NAFLD resolution was driven by the combined phenotype of glucose intolerance and obesity.
