Prevalence rate of elderly childbearing
Elderly childbearing refers to the pregnancy and childbearing of women over 35 years old. With the development of social economy and the improvement of people's education level, more and more women choose to delay childbearing, which also leads to the increase of the prevalence of elderly childbearing. The prevalence rate of elder childbearing will be described in detail from four aspects below.
1. Prevalence rate of reproductive system diseases
Women who have given birth at an advanced age have certain risks in the reproductive system. As women grow older, their ovarian function gradually declines, and their egg quality also decreases, thus increasing the risk of infertility. Some studies have shown that the prevalence of infertility among women over 35 years old is about 30%, while the prevalence of infertility among women under 25 years old is only about 10%. In addition, the elderly fertility is also easy to cause diseases such as hysteromyoma and endometriosis.
The impact of aging on the reproductive system also includes a higher rate of miscarriage and premature delivery. Due to physiological changes, older pregnant women are prone to abnormal embryonic development, chromosome abnormalities, etc., increasing the risk of abortion and premature delivery. A study on pregnant women over 40 years old found that their abortion rate was more than twice that of pregnant women under 30 years old.
Therefore, the prevalence rate of reproductive system diseases in elderly women is higher than that in young women.
2. Prevalence rate of complications during pregnancy
Older pregnant women face more risk of complications during pregnancy. Due to the decline of body organ function, older pregnant women are more likely to have pregnancy complications such as hypertension, diabetes, pregnancy anemia, etc. A study found that the risk of gestational diabetes mellitus for women over 35 years old was three times that for women under 25 years old.
Older pregnant women also face a higher incidence of fetal abnormalities. Chromosome abnormalities, amniotic fluid embolism, placental abruption and other complications are more common in elderly pregnant women. A study found that the risk of chromosomal abnormalities in pregnant women over 40 years old was 20 times that in pregnant women under 25 years old.
Therefore, the incidence of complications in the pregnancy period of older pregnant women is higher than that of younger pregnant women.
3. Prevalence rate of fetal dysplasia
The fetus conceived by older women is prone to chromosomal abnormalities, such as Down syndrome. This is because the quality of female eggs decreases with age, and the risk of abnormal chromosome division also increases. A study shows that the risk of fetal chromosomal abnormalities in pregnant women over 40 years old is 20 times that in pregnant women under 25 years old.
In addition, the elderly birth also increases the risk of fetal intrauterine growth retardation, low birth weight, premature delivery and other problems. These factors may have a long-term negative impact on the health of the fetus.
Therefore, the prevalence of fetal dysplasia in the elderly is higher than that in the young pregnant women.
4. Prevalence rate of mental health problems
Older childbearing often brings more psychological pressure. For women, worrying about their own health problems, worrying about the health of the fetus, and worrying about future childcare may lead to mental health problems. Some studies have found that depression and anxiety symptoms of older pregnant women are more common than those of younger pregnant women.
Mental health problems may also have a negative impact on the overall health of pregnant women, and may affect the development of the fetus and the relationship between mother and baby.
To sum up, the prevalence rate of elderly childbearing is higher than that of young pregnant women in terms of reproductive system diseases, pregnancy complications, fetal abnormalities and mental health problems. Therefore, elderly women should pay attention to their own health status when choosing to give birth, actively communicate with doctors, and receive regular physical examination to reduce the risk of illness.
