What are the risks of having a baby at an advanced age?

Advanced maternal age is defined as a pregnant woman whose age at delivery is ≥35 years. With the change in the concept of childbirth and the progress of medical technology the proportion of advanced maternal age is increasing. The risk of delivery is increased due to the varying degrees of decline in the function of reproductive organs. Clinical studies have shown that advanced maternal age has a high risk of delivery and a high incidence of pregnancy complications and complications, which not only threaten the mother’s health but also increase the incidence of intrauterine distress, neonatal asphyxia, and birth defects. As women age, ovarian function gradually deteriorates, egg quality decreases, and chromosomal abnormalities in the process of fertilization increase, which can easily lead to fetal malformations; the reproductive and endocrine functions of older women gradually decline, and the arteries in the myometrium begin to sclerosis and vascular elasticity decreases, which can easily induce the occurrence of hypertensive disorders during pregnancy; increasing age also leads to a decrease in insulin sensitivity, which can easily lead to the occurrence of gestational diabetes. In addition, as women enter late reproductive age and menopause, their ovarian function gradually declines, resulting in a decrease in fertility, which increases the incidence of miscarriage, preterm birth, stillbirth, placenta praevia and premature rupture of membranes. The high blood glucose concentration in pregnant women with gestational diabetes increases the risk of placenta praevia and postpartum hemorrhage due to excessive fetal nutrition and the formation of giant babies; high blood glucose concentration can also increase oxygen consumption and destroy the structure of red blood cells, leading to complications such as fetal hyperbilirubinemia, intrauterine distress and asphyxia. Because of the advanced maternal age, it is common to worry about the safety of pregnancy and delivery and the health of the fetus and the newborn, which often becomes a psychological stressor and directly affects the psychological health of the advanced maternal age, and can lead to depression and anxiety in serious cases.
