    (Sri Lanka Medical Association, 2015) Niriella, M.A.; Kasturiratne, A.; de Silva, S.T.; Perera, K.R.; Subasinghe, S.K.C.E.; Kodisinghe, S.K.; Priyantha, T.A.C.L.; Vithiya, K.; Kottachchi, D.; Ranawaka, U.K.; Jayasinghe, Y.C.; Rajindrajith, S.; Dassanayake, A.S.; de Silva, A.P.; Pathmeswaran, A.; de Silva, H.J.
    INTRODUCTION AND OBJECTIVES: A previous community based study reported a prevalence of 33% for non-alcoholic fatty liver disease (NAFLD) among and urban adult Sri Lankan population. In this follow up study of the same population after 7 years, e reassessed the prevalence and risk factors for NAFLD. 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 men, <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, serum alanine aminotransferase (ALT) and serum creatinine (SCr) with estimated glomerular filtration rate (eGFR) were determined. CKD was defined as eGFR<60ml/min/1.72m2 (KDIGO/KDOQI classification). 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(53.0%) men and 839(67.4%) women] had NAFLD. On multivariate analysis, obesity, abnormal body fat distribution, elevated systolic BP, raised plasma triglycerides, and low HDL were independently associated wth NAFLD. Raised diastolic BP, raised HbA1c, raised ALT and presence of CKD were not associated with NAFLD. 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.

    Prevalence of non-alcoholic fatty liver disease and its risk factors in an urban adolescent cohort in Sri Lanka
    (Sri Lanka Medical Association, 2015) Jayasinghe, Y.C.; Rajindrajith, S.; Kasturiratne, A.; de Silva, S.T.; Niriella, M.A.; Perera, K.R.; Subasinghe, S.K.C.E.; Kodisinghe, S.K.; Priyantha, T.A.C.L.; Vithiya, K.; Pathmeswaran, A.; de Silva, H.J.
    INTRODUCTION AND OBJECTIVES: High prevalence of non-alcoholic fatty liver disease (NAFLD) is reported among adults in Sri Lanka. Although limited data on childhood obesity is available, community prevalence of NAFLD and its risk factors among adolescents is unknown. We investigated the prevalence and risk factors for NAFLD in an urban adolescent birth cohort in Sri Lanka. METHODS: The study population consisted 14 year-olds, belonging to the birth cohort born in 2000, residing in the Ragama Medical Officer of Health area. NAFLD was diagnosed based on established ultrasound criteria. Anthropometric measurements, blood pressure (BP) and total body fat distribution (TBF) estimates were made. Fasting blood sugar, serum insulin, fasting serum lipid and serum alanine aminotransferase (ALT) levels were measured. Independent predictors of NAFLD were determined by multivariate analysis. RESULTS: 508 adolescents [263 (51.8%) girls] participated in the study. Overall 44 (8.7%) had NAFLD [22 (8.4%) girls]. 46 (18.8%) boys and 54 (20.5%) girls had a BMI above the equivalent of 23 kgm2in adults. 44 (17.1%) boys and 77 (29.3%) girls had elevated TBF. On multivariate analysis, having an elevated BMI [OR=10.1 (95% confidence interval: 3.9-29.2) and elevated TBF [OR=4.4 (95% confidence interval: 1.5-12.8)] were independently associated with NAFLD. CONCLUSION: The prevalence of NAFLD among adolescents in this urban Sri Lankan community is high, and is strongly associated with obesity and abnormal TBF. Despite elevated TBF being commoner in girls, we found no gender differences in prevalence of NAFLD among adolescents in this urban Sri Lankan community is strongly associated with obesity and abnormal TBF. Our findings emphasize the needs to access these risk factors through preventive and screening programs.
