    Incidence, prevalence and demographic and life style risk factors for obesity among urban, adult Sri Lankans: a community cohort follow-up study
    (Sri Lanka Medical Association, 2017) Niriella, M.A.; de Silva, S.T.; Kasturiratne, A.; Kottachchi, D.; Ranasinghe, R.M.A.G.; Dassanayake, A.S.; de Silva, A.P.; Pathmeswaran, A.; Wickremasinghe, A.R.; Kato, N.; de Silva, H.J.
    INTRODUCTION & OBJECTIVES: Obesity is a global problem. Data from the South Asian region is limited. METHODS: In a cohort follow-up study we investigated obesity among urban, adult, Sri Lankans (35-64y; selected by age-stratified random sampling from Ragama-MOH area; initial screening 2007; re-evaluation 2014). On both occasions structured interview, anthropometry, liver ultrasound, biochemical and serological tests were performed. Total body fat (TBF) and visceral fat percentage (VFP) were assessed by impedance in 2014. General-obesity (GO) was BMI>25kg/m2. Central-obesity (CO) was waist circumference (WC)>90cm males and WC>80cm females. Multinomial logistic regression was fitted to assess associations. RESULTS: In 2007 (n=2967), 614 (20.7%) were overweight [51.9%-women], 1161(39.1%) had GO [65.9%-women] and 1584(53.4%) had CO [71%-women]. Females (p<0.001), raised-TG (p<0.001), low-HDL (p<0.001), diabetes (p<0.001), hypertension (p<0.001), NAFLD (p<0.001), and low household income (p<0.001) were significantly associated with prevalent GO and CO respectively. Additionally, increased-age (p=0.05), low-educational level (p<0.001) and unhealthy eating (p<0.001) were associated with prevalent CO. Inadequate physical activity was not associated with either. 2137 (72%) attended follow-up in 2014. Of those who were initially non-obese who attended follow-up, 189/1270 (14.9%) [64% women] had developed GO (annual-incidence 2.13%) and 206/947 (21.9%) [56.3% women] had developed CO (annual incidence 3.12%) after 7 years. TBF and VFP significantly correlated with incident GO and CO (p<0.001). Female gender (OR-1.78, p<0.001; 2.81, p<0.001) and NAFLD (OR-2.93, p<0.001; OR-2.27, p<0.001) independently predicted incident GO and CO respectively. CONCLUSION: The prevalence and incidence of GO and CO were high in this cohort. Both incident GO and CO were strongly associated with female gender and NAFLD.

    Prevalence and risk factors for metabolic syndrome among aging adults in an urban Sri Lankan population
    (Sri Lanka Medical Association, 2015) Kasturiratne, K.T.A.A.; Niriella, M.A.; de Silva, S.T.; Perera, K.R.; Subasinghe, S.K.C.E.; Kodisinghe, S.K.; Piyaratna, T.A.C.L.; Vithiya, K.; Kottachchi, D.; Ranawaka, U.K.; Jayasinghe, C.; Rajindrajith, S.; Dassanayake, A.S.; de Silva, A.P.; Pathmeswaran, A.; de Silva, H.J.
    INTRODUCTION AND OBJECTIVES: Metabolic syndrome (MetS) is assumed to be of high prevalence in the Asian region. However, its community prevalence and risk factors in South Asia is poorly studied. We determined the prevalence and risk factors for MetS among adults in an urban Sri Lankan population. METHOD: The study population consisted of 42-71 year old adults, selected by stratified random sampling from the Ragama Medical Officer of Health area. MetS was defined by the International Diabetic Federation criteria with ethnic specific cutoffs. Anthropometric measurements, blood pressure (BP) and body fat distribution estimates were made. Glycosylated hemoglobin, fasting serum lipids, serum alanine aminotransferase (ALT) and serum creatinine (SCr) with estimated glomerular filtration rate (eGFR) were determined. CKD was defined as GFR<60ml/min/1.72m2 (KDIGO/KDOQI classification), USS abdomen was performed to detect fatty liver and non-alcoholic fatty liver disease (NAFLD) was diagnosed on safe alcohol consumption (< 14 units/week for men, < 7 units/week for females) and absence of hepatitis B and C markers. RESULTS: 2155 (1244 [57.7%] women, mean age 59.2 years [SD, 7.7]) participated. 1014 (47.1%) [mean age 59.2 years (SD, 7.7), 256 (28.1%) men; 758 (60.9%) women] had MetS. On multivariate analysis female gender, abnormal total body fat and abnormal visceral fat level (>10%) and presence of NAFLD were independently associated with MetS. Age 65 or more, raised ALT and CKD were not associated with MetS. CONCLUSION: The prevalence of MetS among adults in this aging urban Sri Lankan community was high and is independently associated with female gender, abnormal body fat distribution and presence NAFLD.

    Prevalence and risk factors for Non-Alcoholic Fatty Liver Disease among an urban aging adult Sri Lankan population – Ragama Health Study 7-year follow up
    (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.
