introduction
With the development of society and the improvement of living standards, more and more couples choose to have a second child. However, older women generally face more health risks. Preterm birth is one of the more common complications. Therefore, it is generally believed that the elderly birth of two children will increase the probability of premature birth. This article will discuss this problem from four aspects: physiology, medical research, hospital experience and data analysis.
Physiological factors
Physiological factors are an important factor affecting the rate of premature delivery. With the increase of age, the function of female reproductive system will gradually decline. For example, women's ovarian function will gradually decline, and the quality of eggs will also decline, which will increase the risk of premature delivery. A study published in the Journal of Biology found that the rate of chromosomal abnormalities in the eggs of elderly mothers was higher, which was also one of the reasons for the increased rate of premature delivery.
In addition, older women also face more risks of chronic diseases, such as hypertension and diabetes, which will increase the probability of premature delivery. This is because these diseases will affect the blood circulation of pregnant women and the function of the placenta, which will lead to insufficient fetal oxygen supply, leading to premature delivery.
In addition, the uterine condition of elderly women will also affect the rate of premature delivery. With the increase of age, the elasticity and contractility of the uterus will be weakened, which will lead to premature birth.
Medical research
Many medical studies also support that the elderly birth of two children will increase the probability of premature delivery. For example, a study conducted by the University of California, San Francisco, found that the risk of premature delivery for women over 35 years old was 80% higher than that for women under 25 years old. Similarly, a study by the University of Edinburgh in the UK also found that the risk of premature delivery of elderly mothers was higher than that of young mothers.
These studies show that women's physical condition will change with age, thus increasing the risk of premature delivery.
Hospital experience
Hospital experience also shows that older births with two children will increase the probability of premature delivery. Taking Peking Union Medical College Hospital as an example, the hospital has carried out long-term observation and research on elderly mothers, and found that among mothers over 35 years old, the rate of premature delivery is significantly higher than that of young mothers. This observation is consistent with the previous research results, which further confirms that the elderly birth of two children will increase the probability of premature delivery.
In addition, not only domestic hospitals have similar experience, but also many international hospitals have conducted research on it. For example, the Miami Children's Hospital in the United States has published a study, which shows that the premature delivery rate and the risk of low birth weight babies of elderly mothers are higher than those of young mothers.
Data analysis
Through the analysis of the nationwide data, it can also be found that the elderly birth of two children will increase the probability of premature delivery. According to the data released by the Ministry of Health, the premature delivery rate of women over 35 years old is significantly higher than that of young women, especially those over 40 years old. This data reflects the obvious correlation between the elderly birth of the second child and premature delivery.
Summary
To sum up, the elderly birth of two children will increase the probability of premature delivery. The observation from physiology, medical research, hospital experience and data analysis supports this conclusion. The changes in the physical condition of the elderly parturients, the findings of medical research, clinical observation in hospitals, and data analysis across the country all show the close relationship between the elderly delivery of two children and premature delivery. Therefore, it is particularly necessary to pay close attention to and properly manage the elderly pregnant women with two children to reduce the risk of premature delivery.
