Objective. Rice is the staple diet in many Asian countries. Current endoscopic guidelines advice a 6 h fast for solids and a 4 h fast for liquids before the procedure. However, these guidelines focus on a Western type diet. The aim of the study was to determine if a 6 h fast for rice is sufficient prior to upper gastrointestinal endoscopy (UGIE). Patients and methods. After informed consent, 212 patients referred for UGIE, who had no alarm symptoms, were randomized into two groups in preparation for UGIE. Fasting 6 h after a rice meal (R6) or fasting 10 h after a rice meal (R10). All meals contained lentils and an egg, and were isocaloric. Endoscopic vision was graded as poor, average, or good. Results . In the R10 group ( n = 107) vision was poor in 2 (1.9%), average in 7 (6.5%), and good in 98 (91.6%). While in the R6 group ( n = 105) vision was poor in 30 (28.6%), average in 19 (18.1%), good in 56 (53.3%). The observed difference of percentages among the two groups for endoscopic vision was significant (M-H Chi-Square for trend = 25.67; df = 1; p < 0.001). Conclusions . Fasting for 6 h after a rice based meal seems inadequate for UGIE. Fasting for 10 h significantly improves endoscopic vision. Current guidelines need to be re-evaluated for populations where rice is the staple diet. [ABSTRACT FROM AUTHOR]

Summary: Non‐alcoholic fatty liver disease (NAFLD) is a global health problem. Iron is the leading cause of liver damage in patients with transfusion‐dependent thalassaemia (TDT), and data on the contribution of NAFLD to liver damage in TDT is lacking. Forty‐five heavily transfused TDT patients who did not have biochemical or ultrasonic evidence of liver cirrhosis were evaluated for effects of iron overload, including the presence of diabetes mellitus, hypogonadism, serum ferritin, R2‐MRI‐liver, and liver enzymes alanine aminotransferase and aspartate aminotransferase. Liver fibrosis and steatosis were estimated using transient elastography (TE). Nine (20%) patients had significant steatosis (S1), and their body mass index (BMI) and liver fibrosis scores were higher than in patients without significant steatosis (S0) (p = 0.03 and p = 0.004, respectively). On regression analysis, the controlled attenuation parameter (CAP) score (i.e., degree of liver steatosis) was associated only with increasing BMI. The TE score (i.e., degree of liver fibrosis) was associated with increasing age, CAP score, male gender, and presence of diabetes. Neither liver steatosis nor fibrosis showed significant association with the liver iron concentration or iron‐related organ damage (hypogonadism). In this cohort of TDT patients, steatosis of the liver, which is associated with increasing BMI, appeared to increase the risk of liver fibrosis. [ABSTRACT FROM AUTHOR]

Background and Aim: Current guidelines for upper gastrointestinal endoscopy (UGIE) advise at least 6–8 h fasting for solids and 4-h fasting for liquids. We aimed to determine whether a 6-h fast for solids and one-hour fast for water prior to UGIE gives good endoscopic vision and less patient discomfort. Methods: 128 patients referred for UGIE were given a standard meal 6 h before endoscopy, and then randomized to either nil by mouth for 6 h (group A, n = 65) or allowed to drink water for up to one hour prior to endoscopy (group B, n = 63). Before endoscopy patients were requested to indicate discomfort due to fasting on a visual analog scale. Fluid in the gastric fundus was aspirated, when present, for volume and pH measurements, and endoscopic vision was graded. Results: 53 patients in group A and 43 patients in group B completed the study. Discomfort was significantly lower in group B than group A ( P < 0.0001). Endoscopic vision was good in all 53 patients in group A and 40 in group B, and average in 3 patients in group B. Fluid in the gastric fundus was noted in 11 patients in group A and 16 in group B, but there were no significant differences in volume or pH between groups. There were no complications attributable to endoscopy in either group. Conclusions: A 6-h fast for solids and a 1-h fast for water prior to UGIE gives good endoscopic vision, and causes minimum patient discomfort. [ABSTRACT FROM AUTHOR]

Background: Ileal intubation is the gold standard for a complete colonoscopy. However, despite evidence of clinical benefit ileoscopy is not always attempted due to perceived technical difficulty. Our aim was to compare time taken for ileal intubation using a new position-the prone 12 o'clock position (PP) with the standard method (left lateral 6 o'clock position-LLP).Methods: We performed a pilot study using fluoroscopy to determine the best patient position for ileal intubation. This was the prone 12 o'clock position. Patients were colonoscoped in the left lateral position and then randomized to ileal intubation in the 6 o'clock position(LL) or the 12 o'clock (PP) position.Results: 202 consecutive patients were referred for colonoscopy. Colonoscopy was performed on 150 patients [82 females, mean (SD) age 53 (16) years]. 75 patients were randomized for ileal intubation in the PP and 75 patients in the LLP. Overall, the ileum was successfully intubated in 145 (96%) patients [74 (98.7%) in the PP and 71 (94.7%) in the LLP]. The median (Interquartile Range) ileal intubation time was 12 (10) seconds in the PP and 87 (82) seconds in the LLP (p < 0.0001; Mann-Whitney U test). The ileum was abnormal in 11 (7.5%) patients.Conclusions: During colonoscopy, the prone 12 o'clock position gives a more direct approach to the ileo-caecal valve and significantly reduces ileal intubation time.Trial Registration: Trial Registry: Sri Lanka Clinical Trial Registry Clinical trial registry number: SLCTR/2009/002.

Background: Childhood obesity is a global problem associated with metabolic abnormalities. The gut-liver axis is thought to play a major role in its pathogenesis. Probiotics are known to alter the gut microbiota and, therefore, could be a therapeutic option in the management of childhood obesity-related complications. Purpose: This double-blind randomized placebo-controlled trial evaluated the effects of probiotics on metabolic derangement in obese children with nonalcoholic fatty liver disease/ nonalcoholic steatohepatitis (NAFLD/NASH). Methods: Obese children with NAFLD/NASH treated at the nutrition clinic of the University Paediatric Unit at Lady Ridgeway Hospital, Colombo, were recruited. Anthropometry, body fat, metabolic derangement, and liver ultrasound scan (USS) results were evaluated at baseline and after 6 months. Transient elastography (FibroScan) was performed on a subsample of these patients. Eighty-four patients were recruited and randomized into the probiotics (n=43) and placebo (n= 41) groups. The mean age was 11.3±1.9 versus 12.1±1.5 years in the probiotic and placebo groups, respectively. Baseline parameters including liver disease stage on USS, body fat percentage, fasting blood sugar, lipid profile, liver function, and C-reactive protein showed no significant intergroup differences. Results: In the probiotic group, a statistically significant reduction in body mass index was noted from the baseline value. However, the reduction was not significant compared with the placebo group. There was a significant reduction in triglycerides, aspartate transaminase (AST), alanine aminotransferase (ALT), AST/ALT ratio, and alkaline phosphatase in the placebo group over the treatment period. Although the liver disease stage on USS improved from stage II--III to stage I in a small number of patients in the probiotic-treated group, transient elastography performed in a subsample did not demonstrate significant improvement in either group. Conclusion: Our results indicate that probiotics have no advantage over lifestyle modification for improving obesityassociated metabolic derangement in children. [ABSTRACT FROM AUTHOR]

Background and Aim: Inflammatory bowel disease (IBD) is emerging in the newly industrialized countries of South Asia, South‐East Asia, and the Middle East, yet epidemiological data are scarce. Methods: We performed a cross‐sectional study of IBD demographics, disease phenotype, and treatment across 38 centers in 15 countries of South Asia, South‐East Asia, and Middle East. Intergroup comparisons included gross national income (GNI) per capita. Results: Among 10 400 patients, ulcerative colitis (UC) was twice as common as Crohn's disease (CD), with a male predominance (UC 6678, CD 3495, IBD unclassified 227, and 58% male). Peak age of onset was in the third decade, with a low proportion of elderly‐onset IBD (5% age > 60). Familial IBD was rare (5%). The extent of UC was predominantly distal (proctitis/left sided 67%), with most being treated with mesalamine (94%), steroids (54%), or immunomodulators (31%). Ileocolic CD (43%) was the commonest, with low rates of perianal disease (8%) and only 6% smokers. Diagnostic delay for CD was common (median 12 months; interquartile range 5–30). Treatment of CD included mesalamine, steroids, and immunomodulators (61%, 51%, and 56%, respectively), but a fifth received empirical antitubercular therapy. Treatment with biologics was uncommon (4% UC and 13% CD), which increased in countries with higher GNI per capita. Surgery rates were 0.1 (UC) and 2 (CD) per 100 patients per year. Conclusions: The IBD‐ENC cohort provides insight into IBD in South‐East Asia and the Middle East, but is not yet population based. UC is twice as common as CD, familial disease is uncommon, and rates of surgery are low. Biologic use correlates with per capita GNI. [ABSTRACT FROM AUTHOR]

Background: Crohn disease has low prevalence in Sri Lanka while compared to the West, while intestinal tuberculosis is common in the region. Since clinical, endoscopic and investigation features of Crohn disease overlap with intestinal tuberculosis, differentiating these two conditions becomes a dilemma for the clinician in the intestinal tuberculosis endemic setting. Case summary: An 18-year old Sri Lankan Muslim female presented with chronic abdominal pain and weight loss. Colonoscopy revealed an ulcerated ileocaecal valve and a terminal ileal stricture. Biopsy confirmed Crohn disease with no supportive features to suggest intestinal tuberculosis. Despite treatment with adequate immunosuppression she failed to improve and underwent a limited right hemicolectomy and terminal ileal resection. Histology confirmed intestinal tuberculosis and she made full recover with 6 months of anti-tuberculosis treatment. Conclusion: This case illustrates the importance of reviewing the diagnosis to include intestinal tuberculosis in an endemic setting, when already diagnosed Crohn disease is treatment refractory.

Background: The first case of a coronavirus 2019 (COVID-19) infection in a Sri Lankan was reported on March 11, 2020. The situation in Sri Lanka changed with the rapid increase of personnel contracting COVID-19 in a naval base camp that housed more than 4000 people. This provided a unique opportunity to study the effectiveness of hydroxychloroquine (HCQ) for post-exposure prophylaxis (PEP), while taking stringent, non-pharmacologic, public health measures to prevent spread. Our aim is to study the effectiveness and safety of HCQ for PEP among naval personnel with exposure to COVID-19-positive patients.Methods/design: This is a placebo-controlled, randomized, clinical trial carried out in the naval base camp and quarantine centers of the Sri Lanka Navy, Ministry of Defense, Sri Lanka. Navy personnel who are exposed to a patient with confirmed COVID-19 infection but test negative for the virus on reverse real-time polymerase chain reaction (rRT-PCR) at recruitment will be randomized, 200 to each arm, to receive HCQ or placebo and monitored for the development of symptoms or rRT-PCR positivity for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus for 14 days.Discussion: This trial will provide high-quality evidence of the effectiveness and safety of HCQ as PEP for COVID-19. The study design is unique due to the circumstances of the outbreak in a confined area among otherwise healthy adults, at a relatively early stage of its spread.Trial Registration: Sri Lanka Clinical Trials Registry (SLCTR) SLCTR/2020/011 .

Background: Data on outcomes of non‐alcoholic fatty liver disease (NAFLD) from South Asia are lacking. We compared mortality, among those with‐ and without‐NAFLD, after 10‐years follow‐up among urban, adult Sri Lankans. Method: Participants (aged 35‐64 years), selected by age‐stratified random sampling, were screened by structured‐interview in 2007. Anthropometric measurements, liver ultrasonography and biochemical/serological tests were done. NAFLD was diagnosed on ultrasound criteria, safe‐alcohol consumption (Asian‐standards) and absence of hepatitis B/C. Subjects without NAFLD were those without any ultrasound criteria of fatty liver, safe‐alcohol consumption and absence of hepatitis B/C. The cohort was re‐evaluated to assess mortality in 2017. Participants or their households were contacted by telephone/post, and deaths confirmed by home‐visits and death certificate review. Cox‐regression was used to determine predictors of all‐cause mortality (ACM) and cardiovascular mortality (CVM) in those with‐ and without‐NAFLD. Results: 2724 (91.2%) of 2985 original participants were contacted (851‐with NAFLD and 1072‐without NAFLD). Overall there were 169 (6.2%) deaths [41‐deaths among NAFLD (17‐cardiovascular; 9‐cancer‐related; 4‐liver‐specific; 11‐other) and 79‐deaths among no‐NAFLD (28‐cardiovascular; 17‐cancer‐related; 1‐liver‐specific; 33‐other)]. Metabolic syndrome (MetS), low‐education level, higher age and male‐gender independently predicted ACM. MetS, increasing age and male‐gender independently predicted CVM. NAFLD did not predict either ACM or CVM. In those with NAFLD, MetS and age >55‐years were independently associated with ACM, while MetS and male‐gender were associated with CVM. Conclusion: In this community‐based study, increasing age, male‐gender and MetS, but not NAFLD, predicted 10‐year ACM and CVM. Among those with NAFLD, only those metabolically abnormal were at a higher risk for mortality. [ABSTRACT FROM AUTHOR]

Importance: Poorly controlled hypertension is a leading global public health problem requiring new treatment strategies.Objective: To assess whether a low-dose triple combination antihypertensive medication would achieve better blood pressure (BP) control vs usual care.Design, Setting, and Participants: Randomized, open-label trial of a low-dose triple BP therapy vs usual care for adults with hypertension (systolic BP >140 mm Hg and/or diastolic BP >90 mm Hg; or in patients with diabetes or chronic kidney disease: >130 mm Hg and/or >80 mm Hg) requiring initiation (untreated patients) or escalation (patients receiving monotherapy) of antihypertensive therapy. Patients were enrolled from 11 urban hospital clinics in Sri Lanka from February 2016 to May 2017; follow-up ended in October 2017.Interventions: A once-daily fixed-dose triple combination pill (20 mg of telmisartan, 2.5 mg of amlodipine, and 12.5 mg of chlorthalidone) therapy (n = 349) or usual care (n = 351).Main Outcomes and Measures: The primary outcome was the proportion achieving target systolic/diastolic BP (<140/90 mm Hg or <130/80 mm Hg in patients with diabetes or chronic kidney disease) at 6 months. Secondary outcomes included mean systolic/diastolic BP difference during follow-up and withdrawal of BP medications due to an adverse event.Results: Among 700 randomized patients (mean age, 56 years; 58% women; 29% had diabetes; mean baseline systolic/diastolic BP, 154/90 mm Hg), 675 (96%) completed the trial. The triple combination pill increased the proportion achieving target BP vs usual care at 6 months (70% vs 55%, respectively; risk difference, 12.7% [95% CI, 3.2% to 22.0%]; P < .001). Mean systolic/diastolic BP at 6 months was 125/76 mm Hg for the triple combination pill vs 134/81 mm Hg for usual care (adjusted difference in postrandomization BP over the entire follow-up: systolic BP, -9.8 [95% CI, -7.9 to -11.6] mm Hg; diastolic BP, -5.0 [95% CI, -3.9 to -6.1] mm Hg; P < .001 for both comparisons). Overall, 419 adverse events were reported in 255 patients (38.1% for triple combination pill vs 34.8% for usual care) with the most common being musculoskeletal pain (6.0% and 8.0%, respectively) and dizziness, presyncope, or syncope (5.2% and 2.8%). There were no significant between-group differences in the proportion of patient withdrawal from BP-lowering therapy due to adverse events (6.6% for triple combination pill vs 6.8% for usual care).Conclusions and Relevance: Among patients with mild to moderate hypertension, treatment with a pill containing low doses of 3 antihypertensive drugs led to an increased proportion of patients achieving their target BP goal vs usual care. Use of such medication as initial therapy or to replace monotherapy may be an effective way to improve BP control.Trial Registration: anzctr.org.au Identifier: ACTRN12612001120864; slctr.lk Identifier: SLCTR/2015/020.

Background: Nonalcoholic fatty liver disease (NAFLD) is a common problem across the world. We aimed to determine the prevalence of NAFLD and its associations in Sri Lankan adolescents living in an urban Sri Lankan community.Method: The study population consisted of the birth cohort of the year 2000, residing in the Ragama Medical Officer of Health area. Socio-demographic and anthropometric data [anthropometric measurements, blood pressure and total body fat distribution] of these adolescents were collected by trained data collectors. Fasting blood sugar, serum insulin, fasting serum lipids and serum alanine aminotransferase (ALT) levels were measured and an abdominal ultrasound was performed. NAFLD was diagnosed on established ultrasound criteria for fatty liver and absent alcohol consumption.Results: The study sample consisted of 499 adolescents [263 (51.8%) girls]. Forty two (8.4%) had NAFLD. NAFLD was significantly associated with being breast fed for less than 4 months (33.3% vs. 17.1 in controls, p = 0.02), higher waist circumference (prevalence risk ratio 83.3/20.3, 4.1, p < 0.0001), higher body mass index (prevalence risk ratio 40.5/4.8, 8.4, p < 0/0001),higher HOMA-IR (3.7 vs. 1.9, p < 0.0001) and high triglycerides (prevalence risk ratio 14.3/5.8, 2.5, p = 0.033). Adolescents with NAFLD also had a higher amount of total body fat (p < 0.001) and subcutaneous fat (p < 0.001) than those without NAFLD. The number of children with metabolic derangements was higher among adolescents with NAFLD than those without (85.8 vs 26.3 in controls, p < 0.0001), but a family history of hypertension, diabetes, myocardial infarction or dyslipidaemia were not.Conclusion: Prevalence of NAFLD was high in Sri Lankan adolescents, and was associated with metabolic derangements, especially obesity, insulin resistance and early cessation of breast feeding.

Background This study investigated incidence and risk factors for NAFLD among an adult cohort with 7-year follow-up. Methods The study population (age-stratified random sampling, Ragama MOH area) was screened initially in 2007 (aged 35-64 years) and re-evaluated in 2014 (aged 42-71 years). On both occasions assessed by structured interview, anthropometric measurements, liver ultrasound, biochemical and serological tests. NAFLD was diagnosed on ultrasound criteria, safe alcohol consumption and absence of hepatitis B/C markers. Non- NAFLD controls did not have any ultrasound criteria for NAFLD. An updated case-control genetic association study for 10 selected genetic variants and NAFLD was also performed. Results Out of 2985 of the original cohort, 2148 (72.0%) attended follow-up (1238 [57.6%] women; mean-age 59.2 [ SD-7.6] years) in 2014, when 1320 (61.5%) were deemed NAFLD subjects. Out of 778 who initially did not have NAFLD and were not heavy drinkers throughout follow-up, 338 (43.4%) (221 [65.4%] women, mean-age 57.8 [ SD-8.0] years) had developed NAFLD after 7-years (annual incidence-6.2%). Central obesity ( OR=3.82 [95%- CI 2.09-6.99]), waist increase >5% ( OR=2.46 [95%- CI 1.20-5.05]) overweight ( OR=3.26 [95%- CI 1.90-5.60]), weight gain 5%-10% ( OR=5.70 [95%- CI 2.61-12.47]), weight gain >10% ( OR=16.94 [95%- CI 6.88-41.73]), raised plasma triglycerides ( OR=1.96 [95%- CI 1.16-3.29]) and diabetes ( OR=2.14 [95%- CI 1.13-4.06]), independently predicted the development of incident NAFLD in multivariate analysis. The updated genetic association study (1362-cases, 392-controls) showed replicated association ( P=.045, 1-tailed) with NAFLD at a candidate locus: PNPLA3 (rs738409). Conclusions In this community cohort study, the annual incidence of NAFLD was 6.2%. Incident NAFLD was associated with general and central obesity, raised triglycerides and diabetes, and showed a tendency of association with PNPLA3 gene polymorphisms. [ABSTRACT FROM AUTHOR]

Background: Asthmatics are known to have esophageal hypomotility. Vagal hypofunction and prolonged intra-esophageal acidification cause esophageal hypomotility. The contribution of gastroesophageal reflux (GER) and vagal function to esophageal motility in asthmatics is unclear. We studied the relationship between esophageal motility, GER and vagal function in a cohort of adult asthmatics. Methods: Thirty mild, stable asthmatics (ATS criteria) and 30 healthy volunteers underwent 24-hour ambulatory esophageal monitoring, manometry, autonomic function testing and GER symptom assessment. 27 asthmatics underwent gastroscopy. A vagal function score calculated from 3 tests (valsalva maneuver, heart rate response to deep breathing and to standing from supine position) was correlated with esophageal function parameters. Results: Asthmatics (mean age 34.8 (SD 8.4), 60% female) had more frequent GERD symptoms than controls (mean age 30.9 (SD 7.7), 50% female). 10/27 asthmatics had esophageal mucosal damage, 22 showed hypervagal response, none had a hyperadrenergic response. 14 asthmatics had ineffective esophageal motility. Higher GERD-score asthmatics had significantly fewer peristaltic and more simultaneous contractions than controls, and higher esophageal acid contact times than those with lower scores. All reflux parameters were significantly higher and acid clearance time prolonged in asthmatics than controls (p < 0.001, Mann-Whitney U test). There was no correlation between vagal function score and esophageal function parameters. Conclusions: A cohort of adult asthmatics was found to have peristaltic dysfunction and pathological GER, but otherwise normal esophageal motility. The peristaltic dysfunction seems to be associated with vagal hyperreactivity rather than vagal hypofunction. [ABSTRACT FROM AUTHOR]

Background: Insulin resistance (IR) plays a major role in the pathogenesis of metabolic syndrome. Acanthosis nigricans (AN) is an easily detectable skin condition that is strongly associated with IR. The aims of this study were, firstly, to investigate the prevalence of AN among adults in an urban Sri Lankan community and secondly, to describe its utility to detect metabolic syndrome. Findings: In a community based investigation, 35-64 year adults who were selected using stratified random sampling, underwent interview, clinical examination, liver ultrasound scanning, and biochemical and serological tests. Metabolic syndrome was diagnosed on revised ATP III criteria for Asian populations. AN was identified by the presence of dark, thick, velvety skin in the neck. 2957 subjects were included in this analysis. The prevalence of AN, metabolic syndrome and type 2 diabetes mellitus were 17.4%, 34.8% and 19.6%, respectively. There was a strong association between AN and metabolic syndrome. The sensitivity, specificity, positive predictive value and negative predictive value of AN to detect metabolic syndrome were 28.2%, 89.0%, 45.9% and 79.0% for males, and 29.2%, 88.4%, 65.6% and 62.3% for females, respectively. Conclusions: AN was common in our study population, and although it did not have a high enough sensitivity to be utilized as a screening test for metabolic syndrome, the presence of AN strongly predicts metabolic syndrome.

Background and Aims: Non-alcoholic fatty liver disease (NAFLD) is an emerging problem in the Asia–Pacific region. However, its prevalence and risk factors in Asian (especially South Asian) communities is poorly studied. In this study, the aim was to determine the community prevalence and risk factors for NAFLD among adults in an urban Sri Lankan population. Methods: The study population consisted of 35–64-year-old adults, 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. Blood pressure (BP) and anthropometric measurements were made, and fasting glucose, glycosylated hemoglobin, serum lipids, fasting serum insulin and serum alanine aminotransferase (ALT) were determined. Results: Of the 2985 study participants, 974 (32.6%) had NAFLD (605 [62.1%] women, mean age 52.8 years [standard deviation, 7.3]). On multivariate analysis, obesity, acanthosis nigricans, insulin resistance, elevated diastolic BP, fasting plasma glucose, plasma triglycerides, and ALT twice the upper limit of the reference range or more were independently associated with NAFLD. Conclusion: The prevalence of NAFLD among adults in this urban Sri Lankan community is high and is strongly associated with constituent features of the metabolic syndrome. [ABSTRACT FROM AUTHOR]

Background: The metabolic syndrome (MetS) is a clustering of abdominal obesity, diabetes and prediabetes, high cholesterol and high blood pressure, that confers an increased risk of cardiovascular disease. There is limited data on incidence of MetS from South Asia. This study investigated incidence and risk factors for new onset MetS in an urban adult Sri Lankan population. Methods: Subjects (selected by age-stratified random sampling from the Ragama Medical Officer of Health area) were screened initially in 2007 (35–64 years) and re-evaluated in 2014 (42–71 years). On both occasions they were assessed by structured interview, anthropometric measurements, liver ultrasound, and biochemical/serological tests. MetS was diagnosed on International Diabetes Federation (IDF-2006) criteria. Total body fat (TBF) and visceral fat percentage (VFP) were measured in 2014, using body impedance method. Incidence and factors at baseline, associated with new onset MetS, were investigated among those who presented for re-evaluation. Results: 2985 (99.1%) [1636 (54.8%) women (54.8%); median age (IQR) 53 (47–59) years] from the initial cohort in 2007 had complete data. 2148 (71.9%) [1237 (57.6%) women; median age (IQR) 60 (54–66) years] attended follow-up. 949 of them [701 (73.9%) women; median age (IQR) 60 (54–65) years] had MetS (prevalence 47.2%, 95% CI 45.0–49.4%). Of 1246 who did not have MetS in 2007, 265 [178 (67.1%) women, median age (IQR) 57 (51–64) years] had developed MetS after 7 years (annual incidence 3.5% (95% CI 2.4–4.5%). Females (OR = 4.9, 95% CI 3.4–7.4), BMI > 23 kg/m2 in 2007 (OR = 1.6 per unit increase, 95% CI 1.5–1.7), weight gain (by 2–5% OR = 2.0, 95% CI 1.1–3.5; by > 5% OR = 2.2, 95% CI 1.4–3.4), and increase in waist circumference (by 2–5% OR = 7.0, 95% CI 4.0–12.2; by > 5% OR = 13.4, 95% CI 8.3–22.4) from baseline and presence of non-alcoholic fatty liver disease (NAFLD) in 2007 (OR = 1.70, 95% CI 1.04–2.76) were associated new onset MetS. Those with MetS had abnormal VFP and TBF in 2014 [P < 0.001]. Conclusion: In this study, annual incidence of MetS was 3.5%. Female gender, BMI > 23 kg/m2 and NAFLD in 2007 and increase in weight and waist circumference from baseline were significantly associated with new onset MetS. Obesity was the best predictor of future MetS. [ABSTRACT FROM AUTHOR]
