Item Epidemiology of goitres in Sri Lanka - results of a community based study(Sri Lanka Medical Association, 2008) Fernando, R.; Pathmeswaran, A.; Edirisinghe, D.; Abeysinghe, S.; Atulugama, N.; Bandara, D.; Premathileke, M.BACKGROUND: lodization of salt was made mandatory in Sri Lanka in 1995. Data on the current prevalence and geographic distribution of goitre among the general population is not available. Objectives: To describe the epidemiology of goitre in the population over the age of 10 years in Sri Lanka DESIGN, SETTING AND METHODS: The country (excluding the Northern Province) was divided into 6 ecological zones based on annual rainfall and altitude. From each zone, 18 Grama Niladhari (GN) areas were selected, using the probability proportionate to size (PPS) technique. First household to be sampled was selected at random from the list maintained by the midwife and all eligible people in the house were sampled. The closest household, next to the index household,, was visited and sampling carried out next. The process was repeated until 50 subjects were sampled in a GN area. Each subject was examined by at least two researchers for the presence of a goitre. RESULTS: Total of 5200 subjects were assessed. 66 %( 3,433) were females. Mean (SD) age 36.3(17.3) years. 425 subjects had a goitre. The distribution of goitres according to the WHO categorization - Grades 1, 2, 3 and 4 was 18.6, 68.0, 12.5 and 0.9 percent respectively. Adjusted (age and zone) prevalence among females and males was 11.2% and 2.3% respectively. Adjusted (age and sex) prevalence (95% CI) in the different zones varied between 5.34% in the intermediate zone-south to 7.93% in the wet zone-hills. Overall adjusted prevalence was 6.8% (6.0-7.6). CONCLUSIONS: The prevalence of goitres is 6.8%. There is definite female preponderance. No obvious goitre belt can be discerned.Item Epidemiology of goitre in Sri Lanka in the post-iodization era(Sri Lanka Medical Association, 2015) Fernando, R.; Pathmeswaran, A.; Pinto, M. D.INTRODUCTION: Previous studies of goitre in Sri Lanka proposed the presence of a goitre belt, which was refuted subsequently. Epidemiology of goitre in the post iodization era needs re-evaluation. Objectives To describe the epidemiology of goitre in Sri Lanka. METHODS: A descriptive cross-sectional study was conducted in designated zones except in conflict areas in 2006/2007. An interviewer administered questionnaire was used and patients were evaluated clinically, biochemically and cytologically. RESULTS: Among 5200 participans 426 had goitre. Mean age was 36.3 (SD 17.3) years. Goitre was commonest in the age group 40-49 years with a female pre-ponderance. The prevalence was similar in all zones with pockets of high prevalence in each zone. Overall islandwide adjusted prevalence was 6.8% (95% CI = 6.0-7.6). CONCLUSIONS: There was no identifiable goitre belt.There were pockets of high prevalence in all zones. Goitre remains a public health issue despite universal iodization.
