What is the incidence of birth defects and the incidence of birth defects

In fact, the incidence of birth defects in different countries and regions is relatively high, and there will be different degrees of increase every year, especially in our country, because our country's population base is particularly large, so the incidence of birth defects will be relatively high, I summarized the following points, let's take a look at them together.

First of all, the annual growth rate of babies with birth defects can be observed with the naked eye is about 300,000, and some babies even have symptoms of birth defects until many years after birth, so some data show that the number of children with congenital disabilities in our country has reached 80 to 1.2 million, and this probability can account for about 4% to 6% of the overall number of children, of which 40% of children will be branded with the serious consequences of lifelong disability, 30% of children will die, only 30% The baby is able to get effective** or even just corrected.

In addition, in recent years, there have been more and more babies with perinatal birth defects, and the incidence of birth defects in children in China is about 60%, which can increase by 900,000 cases per year, and children's birth defects have become an important member of the disabled population.

What you need to know is that our country is a country with a relatively high incidence of birth defects, and data show that about 200,000 to 300,000 babies born every year have congenital malformations, which brings serious harm to many families, so what are birth defects? What are the specific symptoms of birth defects? Follow me down the line.

First of all, birth defects mainly refer to some abnormalities in the growth and development of the baby when it is in the mother's womb, which leads to different degrees of deformities and defects in the baby's body after birth. The symptoms of birth defects are varied, especially some physical diseases are also included, such as congenital malformations caused by the morphology of various organs of the body, cleft lips, anencephaly, etc.

In addition, some babies will also have physical dysfunction and loss, such as not being able to speak or hear sound, which is congenital deafness, and some babies will be born with mental retardation. Most babies are born with birth defects, but a few babies have underlying factors that hide symptoms for many years before they are discovered.

Genetic factorsGenetic factors are one of the most important causes of birth defects, mainly due to the abnormal occurrence of genetic material, which is directly related to the parents.

Environmental factorsThe environment in which pregnant women live is also unchanged will cause birth defects, and the unfavorable factors of the surrounding environment will directly ** fetal development abnormalities, and common environmental factors include biology, chemistry, and nutrition.

Biological factorsThe biological factors here mainly refer to the fetal malformations caused by the infection of certain bacteria during the pregnant woman's pregnancy. When a pregnant woman is infected with bacteria, the bacteria will affect the fetus through the blood, resulting in birth defects.

Nutritional reasonsNutritional causes refer to the intake of nutrients during pregnancy, especially the intake of trace elements, which leads to birth defects in the baby.

Other reasonsIf a pregnant woman smokes and drinks alcohol, the probability of birth defects in the baby is also increased. In addition, if you eat poisonous food or are exposed to toxic chemicals, it can affect birth defects.

Birth defects are structural, functional, or metabolic abnormalities that occur before a baby is born and are the leading cause of early miscarriage, stillbirth, infant death, and congenital disability. After relevant research and research, it is shown that there are still a lot of babies born with birth defects every year in China, what is the reason for this? How can we avoid birth defects?

In fact, now that science and technology have been very developed, we can avoid such problems through various examinations, at least the probability can be controlled within the minimum range, why are there still so many children with birth defects? It is because many people do not take this matter to heart, and always feel that the probability of such a thing happening is relatively small, and even if it happens, it will not happen to themselves, we must not have such thoughts, once it happens, it will be very painful, and it is also very cruel, so we must master some methods to avoid birth defects.

First of all, we must do a good job of premarital examination, which is responsible for both parties, and secondly, when we conceive a child, we must give nutrition to the body before childbirth, so as to avoid problems caused by malnutrition, and at the same time we must do a good job of regular examination in the process of pregnancy. In this way, the problem of birth defects can be avoided to a large extent, and we can reduce the probability of paying tribute to things within the scope of our best efforts, and the probability of occurrence is to be responsible for ourselves, our families, and our children, and if we are fishing and devoted, we will face problems that we cannot afford.

I hope that everyone can pay close attention to it, and at the same time, I also call on the people around us to pay attention to it, because only by working together can we make our baby healthy and healthy, and grow up happily.

Birth defects refer to abnormalities in the structure, function or metabolism of the body that occur before the birth of the baby. Husbands and wives should also actively develop various diseases before trying to conceive.

Birth defects refer to the structural and functional metabolism abnormalities that occur in the embryo or fetus during development, which can be caused by genetic factors such as chromosomal aberrations and gene mutations. Individual preventive measures are specific to couples who are planning to have a baby, and should pay attention to: maintaining a healthy lifestyle, such as proper nutrition, quitting smoking, abstaining from alcohol and exercising appropriately, as well as maintaining a healthy psychological state.

Birth defects are defects that a person carries from genes and will exist after birth, such as some natural diseases. If you want to avoid birth defects, you should get tested during pregnancy.

There are two main types of causes, one is maternal or environmental factors, and the other is genetic factors.

1. Maternal or environmental factors.

1. When the radiation dose absorbed by the fetus in the first trimester exceeds 5rad, the risk of fetal malformation will increase significantly;

2. Some chemical agents can cause fetal malformations, especially when used in early pregnancy, so the medication during pregnancy should be used rationally under the guidance of a doctor.

Rural women should avoid exposure to pesticides during pregnancy. Long-term heavy alcohol consumption can lead to fetal alcohol syndrome, which is characterized by microcephaly, mental retardation, and a peculiar facial appearance. Heavy metal leakage (mercury, lead, etc.) increases the risk of fetal malformations.

3. Infection of pregnant mothers with certain microorganisms can lead to fetal infection and fetal malformations, such as rubella, giant cell, herpes simplex, toxoplasmosis, syphilis, etc.

4. High fever in the first trimester.

5. Poor blood sugar control in early pregnancy can increase the risk of fetal malformations, mainly congenital heart disease, neural tube malformations, cleft lip and palate, etc.

6. Dietary factors: Lack of folic acid in food increases the risk of fetal neural tube defects and cleft lip and palate.

2. Genetic factors.

It is a malformation caused by an abnormality in the genetic material from the parents. For example, the parents have chromosomal abnormalities, and the parents carry mutant genes. Sometimes the fertilized egg itself has an abnormal chromosomal segregation or a genetic mutation.

When consanguineous marry, the incidence of certain recessive genetic diseases increases significantly due to the increased risk of both spouses carrying the same abnormal gene, so it is not appropriate for close relatives to marry or have children.
