The Influence of Old Childbearing on Children's Heredity
Elderly childbearing refers to women having children at the age of 35 and above. With the change of modern lifestyle, more and more women choose to delay childbearing. However, the elderly childbearing has some effects on the heredity of children. This article will elaborate on the influence of elder childbearing on children's heredity from the aspects of children's health, intellectual development, genetic diseases and physiological development.
health problem
With the growth of age, the quality of female eggs will gradually decline. Research shows that women aged 35 and over have a significantly increased risk of having children. This is because at this age, the number and quality of female eggs are gradually decreasing, leading to an increase in the probability of chromosomal abnormalities. Among them, the most common abnormality is Down syndrome. Down syndrome is a genetic defect caused by the fetus carrying three chromosomes 21. In addition, older pregnant women are more likely to suffer from pregnancy complications such as gestational diabetes and hypertension, which will have a negative impact on children's health.
In addition, older pregnant women also face a higher risk of spontaneous abortion during pregnancy. This is mainly because the number and quality of female eggs are reduced, which may lead to the weakening of the implantation ability of fertilized eggs and the possibility of spontaneous abortion. Abortion is a psychological and physiological blow to pregnant women, and also has a certain impact on the health of children.
Intellectual development
There may also be some differences in the intellectual development of older children. The study found that due to the poor quality of eggs of older pregnant women, children may lag behind their peers in IQ and cognitive ability. This is mainly because the decline in egg quality will have a certain negative impact on the development of embryos and brain formation.
In addition, children born at an advanced age may also face higher risks of psychological and behavioral problems. This may be related to the parents' older age, limited energy and inability to give their children enough attention and education. Therefore, parents should pay special attention to the intellectual and psychological development of children in the family of older children, and give timely and appropriate help and support.
Genetic disease
Children born at an advanced age are more likely to suffer from certain genetic diseases. This is mainly due to the decline in the quality of female eggs and the increase in the probability of chromosomal abnormalities. Among them, one of the most common genetic diseases is congenital heart disease. Children born to older pregnant women are at significantly increased risk of congenital heart disease, because congenital heart disease is associated with chromosomal abnormalities.
In addition, the elderly fertility is also related to the increased incidence of some genetic diseases. For example, the incidence of osteogenesis imperfecta, familial hypercholesterolemia and other diseases is relatively high in families with older children. Therefore, it is very important for children's health to carry out comprehensive genetic counseling and testing to understand the family genetic history and individual genetic risks before giving birth at an advanced age.
Physiological development
Children born at an advanced age may also have some problems in their physiological development. The study found that the babies born to older pregnant women had lower birth weight and shorter height. This may be related to the decline of maternal age and egg quality. In addition, children born to elderly pregnant women may also face the risk of premature delivery, and the physiological development of premature infants may have a series of problems.
It is worth mentioning that the age of older fathers will also have a certain impact on children's heredity. Research shows that children born to older fathers are also at increased risk of certain genetic diseases. Therefore, both parents should carry out comprehensive genetic counseling and testing when planning the elderly birth, so as to prepare for the healthy future of their children.
summary
The influence of elderly childbearing on children's heredity is mainly reflected in health, intellectual development, genetic diseases and physiological development. With the growth of age, the quality of female eggs declines, leading to a certain risk of children's health and intellectual development. In addition, the incidence of chromosome abnormalities and genetic diseases has also increased. Children born at an advanced age may also have some problems in their physiological development. Therefore, both parents should fully understand the risks and carry out necessary genetic counseling and testing to ensure the health and happiness of their children when planning the elderly birth.
