The prevalence in the Asian society is 16-25%. This may be under-estimated as patients are usually asymptomatic. The interest in this disease is currently heightened as more evidence is showing that a significant proportion of patient with NAFLD can progress to liver cirrhosis, liver failure and hepatoma. Objectives: 1. To determine the prevalence of NAFLD in the adult patients undergoing ultrasound examination for other causes in our outpatient setting. 2. To determine the prevalence of risk factors. Methods: Prospective study from 1 March–31 December 2019. Ultrasound abdomen for patients attending surgical outpatient clinic were screened for the word ‘fatty liver’. Patients fulfilling study criteria were included. Once consented, full history and body measurements were taken, followed by fasting blood test (FSL, FBS, LFT). Data analysis was done using IBM® SPSS® Statistics Version 24. Results: During the study period, 359 patients underwent ultrasound abdomen, 132 had fatty liver and 79 were included in the study. Mean age was 49.01±11.67 years, BMI 26.67±3.61 kg/m2, ALT 40.82±83.40 μ/L, FBS 5.79±1.51 mmol/L, total cholesterol 5.24±0.85 mmol/l and TG 1.47±0.80 mmol/L. Patients with risk factors are male (46.8%), type 2 DM (24.1%), obesity (67.1%), hypertension (49.4%) and hypercholesterolaemia (51.9%). Discussions: The prevalence of NAFLD in our centre is 22%, which is compatible with other western and Asian studies. The prevalence of male risk factor is similar to other Malaysian studies (45-50%). The prevalence of other risk factors is also high. Conclusions: In conclusion, the prevalence of NAFLD is high among our population and the associated factors are mostly obesity and hypercholesterolaemia. These patients are asymptomatic and they are at risk of getting chronic liver disease in the long term.
