[Survey and analysis on correlative factors with CHD in 12,468 pupils in Yimeng mountain area].
The risk factors correlated with congenital heart diseases (CHD) in 12,468 pupils in Yimeng mountain area were surveyed and analysed. The morbidity rate of CHD was 3.05%, which was higher than those of other heart diseases; ventricular septal defect (VSD) was more frequent than other types of CHD. The frequency in pupils in city is higher than in rural areas. In 38 cases with CHD, through analysis (1:1) on the risk of single factor and the progressive regression analysis on compound factors, the results showed that the age of pregnant women (> or = 35 years), the job of mother (chemical worker), the history of coryza in pregnancy (within 3 months), the season of birth (August, September), and the family history of malformation are notably correlated with CHD.
