What is elder childbearing and its medical definition
Elderly childbearing refers to the phenomenon of pregnancy and childbirth of women in the age range of 35 years and above. This definition is related to the biological mechanism of fertility, because the fertility of women decreases with age. According to the definition of the World Health Organization, elder childbearing refers to pregnancy at the age of 35 and above. In the medical field, there are also some other definitions, such as pregnancy at the age of 40 and above, or first pregnancy at the age of 35 and above.
The medical definition of elderly childbearing is mainly based on the decline of female ovarian function. Female fertility mainly depends on the quality and quantity of ovulation in the ovary. With the growth of age, the number and quality of female eggs decrease, which leads to increased difficulty in pregnancy and increased risk of miscarriage.
Association between longevity and fertility
There is a certain correlation between longevity and fertility. On the one hand, longevity may lead to a tendency to postpone childbearing. With the progress of medical technology and the improvement of living standards, people pay more attention to their own professional and personal development. Many women choose to consider childbearing only after their careers are stable, which leads to the phenomenon of postponing childbearing.
On the other hand, fertility is also related to longevity. Some studies have shown that childbirth has a positive impact on women's health. During pregnancy and childbirth, women's bodies will produce a series of physiological changes, such as improving immune function and enhancing bone density, which will help women keep healthy. In addition, childbirth also helps to strengthen family cohesion and social support, which also plays a positive role in personal longevity.
In general, there is a complex interaction between longevity and fertility. The life experience and values of individuals will have an impact on fertility decision-making, and the experience and consequences of fertility will also affect the health and longevity of individuals.
Challenges and risks of elderly childbearing
Older childbearing faces a series of challenges and risks. First, the fertility of women decreases with age, and the risk of miscarriage and threatened preterm birth of pregnant women increases. In addition, older pregnant women are more likely to have pregnancy complications, such as gestational diabetes and hypertension.
Secondly, older pregnant women face greater risks during childbirth. Due to the decrease of the elasticity of uterine muscles and the narrowing of the birth canal, older pregnant women are more likely to have prolonged labor and difficulties in delivery. In addition, older pregnant women may be more prone to obstetric complications such as placental insufficiency and pre eclampsia.
Finally, the risk of genetic diseases is also involved in elderly childbearing. Mutations and abnormalities in children's genetic information may increase the risk of congenital diseases. Especially for women over 40 years old, the risks of chromosome abnormalities and Down syndrome will increase significantly.
epilogue
Elderly childbearing refers to the phenomenon of pregnancy and childbirth of women in the age range of 35 years and above. There is a certain relationship between longevity and fertility. On the one hand, longevity may lead to the trend of postponing fertility, and on the other hand, fertility is also conducive to women's longevity. However, the elderly fertility also faces a series of challenges and risks, including fertility decline, increased complications during pregnancy, difficulties in delivery and increased risk of genetic diseases. Therefore, women should pay attention to the related medical risks and consequences when considering elderly childbearing, so as to make a wise choice.
