Will the birth of ultra elderly children increase the infant mortality rate?
Over age childbearing refers to women who are 35 years old or older and have babies. With the development of social economy and the improvement of people's requirements for family life, more and more women choose to be pregnant at a later age. However, some studies have shown that very old childbearing may increase the infant mortality rate. This article will elaborate on this issue from four aspects: physiological changes, genetic risks, pregnancy complications and lifestyle.
Physiological changes
With the increase of age, a series of changes will take place in the female reproductive system. For example, the ovarian function will gradually decline, the quality and quantity of follicles will decrease, and the quality of eggs will also decline. These physiological changes may increase the risk of difficult pregnancy and infant development problems. Some studies have found that very old pregnant women may be more prone to chromosomal abnormalities, such as Down syndrome. These chromosomal abnormalities increase the risk of infant death and congenital defects.
In addition, the uterine environment of very old pregnant women may also affect the growth and development of the fetus. Studies have shown that the ability of the uterus to supply blood and nutrients decreases with age, which may lead to fetal dysplasia and infant death.
Although the influence of physiological changes on the rate of infant death after delivery is still controversial, the physiological limitations of ultra old childbearing may increase the risk of infant death.
Genetic risk
The intrauterine environment of very old pregnant women may be affected not only by age factors, but also by genetic factors. Some studies have found that very old pregnant women are more likely to carry genes of some genetic diseases, such as congenital heart disease, Down syndrome, etc. These genetic diseases will increase the risk of infant death.
In addition, very old childbearing may also increase the complex genetic risk of diseases. The study found that the children of older pregnant women are more likely to suffer from adult diseases, such as diabetes, hypertension, etc. These diseases will increase the infant mortality rate and have a long-term impact on children's future health.
Pregnancy complications
A series of complications may occur in the course of pregnancy due to the decline of physical functions of ultra old pregnant women. For example, gestational diabetes, pregnancy induced hypertension, etc. make pregnant women more prone to pregnancy complications, such as placental dysfunction, pre eclampsia, etc. These complications may affect the normal development of the fetus and increase the risk of infant death.
In addition, very old pregnant women may face more risks during childbirth. Due to the decline of uterine muscle strength, labor may be more difficult, leading to fetal hypoxia and other complications. These factors may also increase the risk of infant death.
life style
The lifestyle of very old pregnant women may also have an impact on the infant mortality rate. Some studies have found that excessive workload and stress may increase the risk of pregnancy complications and fetal development problems. In addition, smoking, excessive drinking and unhealthy eating habits may also lead to poor fetal development and infant death.
To sum up, the birth of very old children may increase the infant mortality rate. Physiological changes, genetic risks, complications during pregnancy, lifestyle and other factors may have an impact on the infant mortality rate. Therefore, very old pregnant women should pay special attention to their health and lifestyle, and carry out prenatal examination and pregnancy management under the guidance of doctors to reduce the risk of infant death.
