title: Risk factors of non-alcoholic fatty liver disease.
abstract: This case control study was carried out in Mymensingh Medical College Hospital, Mymensingh, Bangladesh and Dhaka Medical College Hospital, Dhaka, Bangladesh from November 2010 to October 2011 to find out the risk factors of non-alcoholic fatty liver disease. A total of 90 participants (45 cases and 45 controls) were included. A higher proportion of patients with age >45 years were found in case group compared to control (51.1% vs. 15.6%). The mean age was significantly higher in case group 49.8±12.6 years. Males demonstrated their predominance in both case (62.2%) and control (68.9%) groups, although the two groups did not differ in terms of sex distribution. Body mass index demonstrates that 26.7% of patients in case group were of normal weight, 46.7% overweight and 26.7% obese. In the control group, two-thirds (68.9%) of the patients were of normal weight and 24.4% overweight and 7.8% obese. Diabetes and hypertension were significantly present in the case group than those in control counterparts 75.6% vs. 15.6% and 86.7% vs. 15.6 % respectively. The mean fasting blood glucose, ALT, total cholesterol and triglycerides were significantly higher in case group compared to control group 7.8±1.3 vs. 5.4±2.5mmol/L (p<0.001); 39.1±12.4 vs. 30.3±14.1IU/L, (p=0.002); 239.9±14.3 vs. 183.3±11.4mg/dl, (p<0.001) and 183.6±12.5 vs. 133.5±16.0mg/dl, (p<0.001) respectively. However, no significant difference was observed between the case and the control groups in terms of HDL cholesterol (35.9±1.2 vs. 38.0±1.1mg/dl, p=0.203). Majority of the patients in case group (88.9%) exhibited increased echogenicity of liver on ultrasonogram as opposed to 15.6% in the control group.
