<abstract xmlns="http://www.w3.org/1999/xhtml"> Background: Rheumatic fever (RF), rheumatic heart disease (RHD), and congenital heart disease (CHD) are still major problems among Thai school children.Objective: To examine trends in the prevalence of RF/RHD and CHD along with the socioeconomic status of school children in urban Khon Kaen, northeastern Thailand.Methods: We conducted cross-sectional survey of 8,555 school children aged 5-15 years from 4 schools in urban Khon Kaen from January to March 2006. Pediatric cardiologists examined the school children and all cardiac diagnoses were confirmed by echocardiography. Socioeconomic data were also collected. Schools were divided into high and low socioeconomic status (SES) schools, based on the prevailing levels of parental education and household income. All positive cases of heart disease were followed and reviewed at a university hospital up to December 2013.Results: Of 8,555 children examined, 2 had RF/RHD, and 10 had CHD. The prevalence of RF/RHD was 0.23 per 1,000 (95% CI 0.03-0.84), and the prevalence of CHD was 1.2 per 1,000 (95% CI 0.56-2.15). Prevalence of RF/RHD among urban school children in the center of northeastern Thailand had declined from 1.13 to 0.23 per 1,000 since 1986. The indices of socioeconomic development revealed marked improvement during this 20 year interim. The prevalence of RF/RHD was higher among low SES schools (4.6 per 1,000) compared with high SES schools (0 per 1,000).Conclusion: There is a low prevalence of RHD in school children in this region compared with the period before 1986.</abstract>
