Understand the difference and relationship between elder childbearing and close marriage
Elderly childbearing and inbreeding are two different but somewhat similar concepts. They are all related to human reproductive health and genetic risks. However, elder childbearing refers to the phenomenon that women are pregnant and childbearing at a later age, while close relative marriage refers to the marriage relationship between relatives. In this paper, we will discuss the differences and connections between the two concepts from the aspects of physiology, genetics, society and psychology.
Physiological differences
There are obvious physiological differences between elder childbearing and inbreeding. Older childbearing is mainly aimed at women. With the growth of age, the quality and quantity of female eggs will gradually decline, thus increasing the risk of pregnancy and childbirth. Close relative marriage is more related to male fertility. Because of the similarity of genetic factors between relatives, close relatives have a higher risk of carrying genetic diseases than non relatives.
In addition, elderly childbearing is more common in obstetrics and gynecology hospitals, such as Peking Union Medical College Hospital and the First People's Hospital affiliated to Shanghai Jiaotong University. These hospitals have professional teams to deal with relevant problems. However, close marriage is more influenced by culture, religion, law and other factors, and different countries and regions have different regulations and views on it.
Genetic differences
There are also different characteristics in genetic risk between elder childbearing and inbreeding. The risk of elder childbearing is mainly reflected in the increased probability of the fetus suffering from chromosome abnormalities and genetic diseases. The development of technologies such as intrauterine examination and fetal gene detection makes it more feasible and accurate to carry out risk assessment and screening for elderly pregnant women.
The genetic risk caused by inbreeding is mainly due to the fact that both parties carry similar genetic variations, so they have the same risk of genetic diseases. In the world, some common genetic diseases, such as thalassemia, cystic fibrosis and some autosomal recessive genetic diseases, the higher the degree of close marriage, the greater the risk of disease. Therefore, consanguineous marriage has become a concern of the medical community in some regions.
Social and psychological differences
There are also differences in social and psychological aspects between elder childbearing and close marriage. Elderly childbearing is often concerned and pressured by society. Women may delay childbearing after entering the workplace, thus facing higher risks of pregnancy and childbirth. However, close marriage is often influenced by culture and religion. Some regions encourage close marriage, which is believed to help maintain family interests and blood purity.
From the psychological perspective, women who give birth at an advanced age may face anxiety and stress, especially the increased risk of fetal abnormalities and genetic diseases related to pregnancy over 35 years old. However, both parties who are closely related to each other may face concerns about the complexity of kinship and genetic diseases, which will have a certain impact on marital relations and family harmony.
summary
Elderly childbearing and inbreeding are two different but somewhat similar concepts. Elderly childbearing mainly involves women's reproductive health. With the growth of age, the risk of pregnancy and childbirth increases; Close relative marriage is more related to the marriage relationship between relatives, which will increase the risk of genetic diseases. In addition, there are also some differences in heredity and social psychology between elder childbearing and inbreeding. Understanding these differences will help people make more intelligent choices and decisions in life, and improve the quality of life and health.
