A few days ago, reporters learned from the Nanjing Family Planning Association that statistical data from the Jiangsu birth defects intervention project showed that the birth defect incidence rate at the two project sites in Nanjing, Liuhe and Basalt, reached 16.6‰, which is far higher than Our province’s is 8.32‰.
The Jiangsu birth defects intervention project carried out by my country screened pregnant women in 19 counties and districts in our province, involving a total of 2,809 pregnant women, 2,339 high-risk pregnant women were found, and the proportion of birth defects found was 8.32‰. Compared with our province, the two new project sites in Nanjing, Basalt and Liuhe, have a much higher proportion of birth defects. These two new project sites involved a total of 344 pregnant women, and 57 people with birth defects were screened out. Occupying 16.6‰. Among them, the number of babies with birth defects detected in Liuhe was the highest among all projects in our province, with 40, followed by 33 in Wujiang.
Harelips rank first among birth defects in Nanjing
"There are only dozens of birth defects that can be intervened at present. Compared with the more than 4,000 genetic diseases, they can be said to be very few." Xue Xinkun said that among the many hereditary diseases here, there are only more than 400. Diversity can be identified. The top five birth defects in Nanjing in 2006 were harelips, abnormal fingers (toes), neural tube defects, congenital heart disease and ear deformities. Experts say that birth defects are related to a variety of factors, of which genetic factors account for 25%. Environmental factors account for 10%, and genetic factors and environmental factors together account for 65%.
Women over the age of 30 have the highest number of fetuses with malformations
The project also showed the following characteristics: as the number of pregnancies increases, the proportion of birth defects increases; the rate of birth defects among pregnant women aged 25 to 28 is the lowest, and the rate of birth defects among pregnant women over 30 years old The largest; with the improvement of women's education level, the birth defect rate has decreased; the development of modern electronics, chemical plants and other industrial production has made air, light, and noise pollution more serious, thus causing the birth defect rate to show an increasing trend. According to relevant doctors, petrochemical equipment manufacturing waste gases pollute the air, which can increase perinatal and infant mortality rates. Moreover, the incidence of pregnancy abnormalities in polluted areas has increased significantly, and pregnant women have stillbirths. The proportions of miscarriages, stillbirths, newborn deaths and congenital defects are significantly higher than in non-polluted areas.
According to doctors, preparing for the third month of pregnancy is particularly important for the growth and development of the fetus. If pregnant women are often exposed to radiation, toxic substances, etc. in early pregnancy, it is very easy to cause problems such as harelips, congenital absence of anus, and esophageal atresia. Lack of folic acid tablets can cause neural tube defects, such as anencephaly, spina bifida, congenital meningitis, etc. In addition, rubella virus, rubella virus, etc. can cause congenital heart disease, congenital cataracts and congenital deafness; and pregnant women who like to keep animals are likely to be infected with Toxoplasma gondii virus, which will directly cause cerebral insufficiency and congenital amyloidosis in the fetus. Blindness, meningitis, etc.
Many birth defects can be prevented
Xue Xinkun said that birth defects may actually be preventable. As long as the prevention knowledge is mastered, many birth defects can be prevented. For example, rubella virus infection can cause congenital heart disease and congenital deafness in fetuses. Prevent rubella virus infection by getting the rubella vaccine; you can take "Slilian" folic acid in the third month of pregnancy to prevent fetal neural tube defects. Therefore, the Nanjing Population and Family Planning Policy Federation has considered increasing the publicity and planning of birth defect knowledge for age-appropriate groups. In addition, during pregnancy, as long as you create a perinatal health care card in time and go to the hospital for prenatal check-ups on time, birth defects can be discovered and intervened as soon as possible.
