The impact of artificial abortion on women’s re -pregnancy

Since the implementation of the "comprehensive two -child" policy in 2016, my country’s population birth rate has been reduced from 12.95 ‰ to 7.52 ‰ in 2021, and the number of births in the same period has dropped from 17.86 million to 10.62 million, a decrease of over 40%.In August 2022, 17 departments including the National Health and Health Commission jointly introduced 20 fertility encouragement measures.However, the contradiction with the decline in the birth of the birth is that the total number of artificial abortion in my country has been high for a long time. From 2016, the annual annual labor output of the country fluctuates between 9 million to 10 million.National surveys show that 95% of artificial abortion is caused by non -willing pregnancy; within 2 years after birth, 75% of non -willing pregnancy ended through artificial abortion.In the context of the relaxation of my country’s fertility policy, the impact of artificial abortion on women’s fertility and health has become the focus of social attention.

There are many types of abortion technology. Early pregnancy termination technology mainly includes negative pressure suction (for termination of pregnancy within 10 weeks of pregnancy), Dilation and Curettage, D & C, used to terminate 10 ~ 14 weeks of pregnancy) andMi -perone is compatible with prostaglandin (drug abortion, which can be used to terminate pregnancy within 16 weeks).The main termination technology of end pregnancy mainly includes the induction of Eydine, the induction of water sac, and the fetal cesarean section.From the perspective of reproductive epidemiology, this article explores the impact of artificial abortion on women’s re -pregnancy ability and bad pregnancy ending, with a view to providing the basis for women’s fertility protection and subsequent in -depth research.

The impact of artificial abortion on women’s re -pregnancy ability is one of the most concerned about fertility and health issues in my country.

The British forward -looking (433 women with artificial abortion and 1035 women with no artificial abortion) and two -way queue (9299 pregnant women) have not seen the history of artificial abortion and women’s rehabilitation rate.Chinese scholars compare 242 cases of secondary infertility and 656 natural conceptions. Studies have shown that female artificial abortion between 25 and 35 years old increases the risk of secondary infertility, and the risk of repeated abortion is greater.

In terms of research and design, the sound research results of the forward -looking queue and the disease registration system are higher than the level of retrospective research and case control research evidence. Therefore, this article believes that previous artificial abortion has a less impact on women’s re -pregnancy ability or even none of them.Influence.However, the birth registration data does not include important mixed variables such as reproductive system infection, willingness to grow, frequency of sexual life, and contraception, which affects the reliability of its conclusions.The impact of drug abortion on women’s re -pregnancy ability also requires more rigorous design of clinical research.

This article is based on natural miscarriage, premature birth (<37 gestational week), low birth quality (LOW BIRTH Weight, LBW, <2500G), and Small for Gestational Age (SGA), to explore the endless pregnancy ending of abortion against adverse pregnancy.Impact.

1. Natural abortion: The possibility of surgical abortion increases the risk of natural abortion.The lack of high -level evidence between the relationship between drug abortion and natural abortion needs to be continued to be studied.

2. Premature birth and LBW: Due to the short time in the palace, premature babies are often accompanied by LBW.This article believes that artificial abortion is a risk factor for premature birth and LBW. Repeated abortion and medium -term induction of premature production and LBW are greater.The risk of premature birth and LBW of primary maternal drug logistics has not increased; early effects of abortion and abortion of pregnancy and surgical abortion on early maternal premature birth and LBW are close.There are fewer levels, looking forward to more research to verify.

3. SGA: Artificial abortion may be the independent risk factor of SGA.Research and design choices: As far as the level of evidence is concerned, it is generally random control research> forward -looking queue> two -way queue> retrospective queue> case control> case report.Due to ethical problems, the impact of artificial abortion on re -pregnancy in a random control method is not feasible. Therefore, the forward -looking queue is the best design solution, followed by two -way queue and retrospective queue.The selection of research objects and control groups and reasonable statistical methods: The representativeness of the research object is the core issue of epidemiological research, and obtaining the data of the whole population is the optimal option.Secondly, we must try to use multi -central research design to reduce the probability of selectively bias for research objects.In order to reduce selective bias, random methods should be selected in order to reduce selective bias.If the description of the research object incorporation and the screening process is unknown, the incidence of bad pregnancy ending is much higher than that of the general population, and the probability of selective bias in the research object will be relatively large.The control group selection is another point and difficulty in this class.Factors such as pregnancy, birth, pregnancy interval, etc. are closely related to the ending of pregnancy. For example, the risk of LBW, the first pregnancy and first pregnancy, is usually higher than that of the maternal maternal. Analyzing the impact of artificial abortion needs to control the mixed effect of production.The impact of drug abortion on re -pregnancy: The main evidence of this article comes from the research of birth and miscarriage registration data or queue research.After 2000, drug abortion gradually became popular in Europe and the United States. Therefore, the results of the research before 2000 reflected the impact of surgical abortion. After 2000, a large number of studies were also based on surgical abortion and supplemented by drug abortion.Comparing the safety of drug abortion and surgical abortion also requires more research on reproductive epidemiological research to verify.Persistence risk of artificial miscarriage on the re -pregnancy: The scale of artificial abortion in my country is huge, but its absolute risks and crowd attribution risks for women in my country and their ending are not well known.The main reason is that my country lacks artificial abortion big data with good representatives and large samples.Key people and measures for fertility protection: So far, relevant domestic professional groups have published a series of fertility protection expert consensus.Patients with endometriosis have a greater impact on the reproductive system.There are a large number of teenagers in my country entering the childbearing period every year. They are the main force of future fertility, but domestic sex education is relatively backward. Domestic teenagers generally lack contraceptive knowledge and experience, and unexpected pregnancy and artificial abortion risk are higher than adults.As a remedy for accidental pregnancy, it is difficult to disappear in abortion. Therefore, the nature and reproductive health education in my country need to be strengthened.
