BACKGROUND & AIMS A previous community based study reported a prevalence of 33% for Non-alcoholic Fatty Liver Disease (NAFLD) among an urban adult Sri Lanka population. In this follow up study of the same population, after 7 years, we reassessed the prevalence and risk factors for NAFLD. RESULTS Of the 2985 original study participants, 2155 (72.2%) (1244 [57.7%] women, mean age 59.2 years [SD 7.7]) participated in the present study. 1322 (mean age 58.9 years [SD 7.6], 483 men and 839 women) had NAFLD (61.35% of all participants) (Table 2). METHODS The study population consisted of 42-71 year- old adults, originally selected by stratified random sampling. NAFLD was diagnosed on established ultrasound criteria for fatty liver, safe alcohol consumption (<14 units/week for males,<7 units/week for females) and absence of hepatitis B and C markers. Anthropometric measurements, blood pressure (BP) and body fat distribution estimates were made. HbA1c, fasting serum lipids, and serum alanine amino transferase (ALT) were determined. CONCLUSION The prevalence of NAFLD among adults in this aging urban Sri Lankan community has increased over 7 years and is independently associated with constituent features of the metabolic syndrome.

Raised diastolic BP, raised HbA1c and raised ALT were not associated with NAFLD (Table 3). CI – Confidence Interval; NS – Not significant
