Advanced maternal age is generally defined as a woman whose first pregnancy is at least 35 years of age, or who was at least 34 years of age at the time of conception.Non-first-time mothers over 35 years of age are not generally categorized under this concept. There is no special method of calculating the age of an advanced maternal age, as long as the age and pregnancy conditions are met. The reason for using 35 years of age as the cut-off age is that women above that age have a certain degree of decline in body mass and egg quality, which can easily lead to intrauterine growth retardation and preterm labor. They are also more prone to miscarriages, pregnancy complications and co-morbidities, and congenital defects than those in the younger age groups. The potential risks of pregnancy in older women need to be addressed accordingly. For the risk of miscarriage, it is recommended to do a good job of maintenance of ovarian function before pregnancy, and keep a happy mood can effectively reduce the incidence of miscarriage; for various types of pregnancy complications, it is necessary to actively control hypertension, hyperglycemia and other primary illnesses, and regular pregnancy checkups; for congenital defects, a comprehensive pre-pregnancy checkup can be carried out, including chromosomes and genes, and other abnormalities, and then decide whether to get pregnant. For women of advanced maternal age, in addition to preventing common problems, attention should also be paid to the occurrence of hemorrhage and obstructed labor. In addition, the incidence of postpartum depression is relatively high among women of advanced maternal age, and care should be taken to maintain a good state of mind.
