How old is the oldest child?
With the progress of society and the improvement of living standards, more and more women choose to delay pregnancy or childbirth. However, for women, age will have an impact on fertility to some extent. So, what is the age of old childbearing? What is the impact of old childbearing on babies? Next, we will elaborate from four aspects: age limit, fertility, child health and maternal health.
Age limit
According to the age definition of the European Society of Assisted Reproductive Medicine (ESHRE), women aged 35 and above are considered as elderly mothers. This is because the number and quality of female eggs will gradually decline with age, leading to a decline in fertility. In addition, the laws of some countries stipulate that women over 40 years of age need to undergo various medical examinations and consultations before giving birth to ensure that they can bear the risks of pregnancy and childbirth.
However, age is not an absolute limit. For some women in good health, the elderly over 35 years of age may also be successful in childbirth. However, the older you are, the greater the risk of pregnancy and childbirth.
Fertility
With the growth of age, women's fertility will gradually decline. This is mainly because the number of female eggs will decrease, and the quality will also become worse. Women's ovaries contain all eggs at birth. With the growth of age, the number of eggs gradually decreases, and there may be eggs with chromosomal abnormalities. This increases the difficulty of pregnancy and the risk of chromosomal abnormalities in embryos.
According to a study by Peking Union Medical College Hospital, the pregnancy success rate of women over 35 years old is only 30%, while that of women over 40 years old is even lower, only about 10%. Therefore, for older pregnant women, both pregnancy and childbirth need more efforts and risks.
Child health
The elderly childbearing will also have a certain impact on the baby's health. The study found that babies born to older mothers were more likely to suffer from chromosome abnormalities and congenital heart disease than young mothers. This is because the aging of women will increase the risk of chromosomal abnormalities, which will lead to abnormal embryonic development.
In addition, older pregnant women are more likely to suffer from pregnancy diseases, such as pregnancy induced hypertension and diabetes. These diseases may have a negative impact on the health of the fetus, increasing the risk of premature delivery and low birth weight.
Health of pregnant women
Older pregnant women themselves also face certain health risks. During pregnancy, women's bodies will experience many changes and need to bear more physical burdens. Due to physiological aging and the existence of chronic diseases, older pregnant women may be more prone to pregnancy complications, such as pregnancy hypertension and pre eclampsia.
Therefore, for older pregnant women, a comprehensive physical examination should be carried out before pregnancy to ensure that their physical condition can bear the risk of pregnancy and childbirth.
Summary
For women, 35 years of age and above are considered to be the oldest child. The impact of elderly childbearing on babies is mainly reflected in the health of children, who are prone to chromosome abnormalities, congenital heart disease and other diseases. At the same time, the elderly pregnant women themselves also face certain health risks, such as pregnancy hypertension and pre eclampsia. Therefore, women who plan to delay childbirth or pregnancy should make decisions based on their own fertility and health status.
