Background/AimsNonalcoholic fatty liver disease is related to obesity, metabolic syndrome, and insulin resistance. Nonalcoholic fatty liver disease and metabolic syndrome may also be encountered in non-obese, non-diabetic individuals, and there are no published data about the prevalence of these conditions in non-obese, non-diabetic Turkish subjects. We aimed to determine the difference between non-obese, non-diabetic nonalcoholic fatty liver disease patients and healthy controls in terms of insulin resistance and metabolic syndrome in Turkish subjects.Materials And MethodsNon-obese, non-diabetic individuals (n=219) were enrolled. The cohort was divided into two groups according to presence of steatosis in ultrasonography: nonalcoholic fatty liver disease group (n=143) and healthy control group (n=76). Insulin resistance and metabolic syndrome were analyzed and compared between the two groups.ResultsThe prevalences of metabolic syndrome (32.2% vs. 5.3%, respectively; p<0.001) and insulin resistance (46.2% vs. 9.2%, respectively; p<0.001) were significantly higher in the nonalcoholic fatty liver disease group. According to multiple logistic regression analysis, age (odds ratio 1.534; p=0.0032), insulin resistance (odds ratio 1.074; p<0.001), and serum ALT levels (odds ratio 1.102; p<0.001) were independently associated with nonalcoholic fatty liver disease.ConclusionInsulin resistance and metabolic syndrome are not rare in non-obese, non-diabetic Turkish subjects with nonalcoholic fatty liver disease. Ultrasonographically detected fatty liver was independently associated with insulin resistance, irrespective of the presence of metabolic syndrome.
