[The prevalence of congenital heart disease in students of Liangshan prefecture in Sichuan province].
OBJECTIVE
To investigate the congenital heart disease (CHD) prevalence of students in Liangshan prefecture in Sichuan province, and to explore the risk factors of CHD.


METHODS
Stratified cluster sampling was conducted in collecting demographic data. Heart auscultation was used to screening the CHD, and colour Doppler flow imaging was used to diagnose the CHD.


RESULTS
A total of 10,021 student were collected in this study. About 19.74% of total cases had cardiac murmur. Sixty-eight students were diagnosed as CHD through colour Doppler flow imaging, accounting for 0.68%. In addition, the top three ranks of CHD were atrial septal defect, patent ductus arteriosus, interventricular septal defect. Our study also found that per capita income of CHD families was lower than non-CHD families, meanwhile, the CHD prevalence of Yi nationality was higher than other nationalities. There was no statistical significance in age, gender, height, weight, body mass index, head circumference, waist circumference between different types of CHD.


CONCLUSIONS
The CHD prevalence of students in Liangshan prefecture has been in a high level in China; therefore we need pay more attention on screening for the CHD.
