ABSTRACT Background Sri Lanka is considered an endemic region for goiter. Early researchers have suggested the existence of a goiter belt based on rainfall pattern. Subsequent studies done in school children have challenged this theory. Current study is a community-based cross-sectional study done to assess the epidemiology of goiters. Geographic information system (GIS) mapping of the goiter prevalence is developed for the first time in Sri Lanka. Methods Study subjects were selected using a multi-staged cluster sampling with probability proportionate to size (PPS) method. Examination for the presence of goiters was done by two trained investigators and graded. ArcGIS 10 software was used for geostatistical analysis and developing a map by interpolating the data collected for the first time in Sri Lanka. Results A total of 5200 individuals (female—66%, median age—38 years; range 10–92 years) were assessed and 426 goiters were detected. The adjusted prevalence rate of goiters was 6.8%. Kriging interpolation method was used to develop the most appropriate epidemiological map clustering of high prevalence areas with scattered pockets of high prevalence was observed. Current map does not show a prevalence pattern in relation to the rainfall or elevation above sea level as proposed in the past. Conclusion Goiter prevalence in Sri Lanka appears to be different from earlier proposed patterns. Use of GIS has contributed to develop a comprehensive epidemiological map of goiters demonstrating the absence of an endemic goiter belt in the wet zone as proposed earlier.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the world. The determinants of CVD in an urban population using conventional and geographic information system techniques were attempted as a community-based census-type cross-sectional study in Kerala, India, among 1649 individuals residing in 452 households. Sociodemographic details, risk factor exposures, and self-reported disease prevalence were determined. Location of houses, wells from which subjects drew drinking water, and distances of the house from the outer road (proxy for air pollution) were mapped using differential global positioning system and pH of water samples determined. Prevalence of CVD was 5.8%. Significant predictors of CVD were male gender, diabetes mellitus, hypertension, and hypothyroidism. Statistically significant spatial association was found between CVD and groundwater pH. Geographic information system technology is useful in identification of spatial clustering and disease hotspots for designing preventive strategies targeting CVD.

ABSTRACT Objective: To analyze the prevalence of syphilis in during pregnancy and its association with socioeconomic characteristics, reproductive history, prenatal and labor care, and newborn characteristics. Method: A retrospective, cross-sectional study based on gestational and congenital syphilis reports. A (records) linkage was performed in the Brazilian databases: “Information System for Notifiable Diseases” (Sistema de Informação de Agravos de Notificação - SINAN); “Live Births Information System” (Sistema de Informação sobre Nascidos Vivos - SINASC); and “Mortality Information System” (Sistema de Informação sobre Mortalidade - SIM). Results: The prevalence of gestational syphilis was 0.57%. The following associations of syphilis in pregnancy were found: non-white skin color/ethnicity (PR=4.6, CI=3.62-5.76); low educational level (PR=15.4; CI=12.60-18.86); and absence of prenatal care (PR=7.4, CI=3.68-14.9). The perinatal outcomes associated with gestational syphilis were prematurity (PR=1.6 CI=1.17-2.21) and low birth weight (PR=1.6; CI=1.14-2.28). Two deaths from congenital syphilis, one death from another cause and five stillbirths were reported. Conclusion: The results signify a long way until reaching the World Health Organization’s goal of eradicating congenital syphilis.
