Women with Abortion History are at Increased Risk of Delivering Very Preterm Babies in Subsequent Pregnancies

The Detrimental Effects of Adolescent Abortion, Part 1

The Detrimental Effects of Adolescent Abortion, Part 2


WOMEN WITH ABORTION HISTORY AT INCREASED RISK OF DELIVERING VERY PRETERM IN SUBSEQUENT PREGNANCIES– [study published in 4/05 issue, British Journal of Obstetrics and Gynaecology, Reuters Health] Dr. Caroline Moreau et al [Epidemiological Research Unit, Perinatal/Women’s Health, Hopital de Bicetre, France] examined records for 1,943 very preterm infants born before 33 weeks gestation, 276 moderately preterm infants born 33-34 weeks gestation, and 618 full-term infants born 39-40 weeks gestation.

Dr. Caroline Moreau et al concluded that women with a history of abortion were 1.5 times more likely to give birth very prematurely (under 33 weeks gestation), and 1.7 times more likely to have a baby born extremely preterm (under 28 weeks gestation). Their findings were reported in the April issue of the British Journal of Obstetrics and Gynaecology, a peer-reviewed medical journal.

Women who reported having had at least one induced abortion had a 50% higher risk of having a very preterm delivery than women who had never had an abortion. In addition, women who reported having previous abortions had a 70% higher risk of delivering an infant before 28 weeks gestation, compared with women who had never had an abortion.

Abortion increases a woman’s risk of delivering future children prematurely; the risk of very preterm delivery (less than 33 weeks) increases even more dramatically.

The researchers said that previous abortion was associated with an increased risk of very preterm delivery because of premature rupture of the membranes, unexplained spontaneous preterm labor and bleeding  not associated with maternal hypertension (high blood pressure) [Reuters Health].

Researchers found no association between previous abortion and very preterm delivery because of maternal hypertension.

Conclusion: induced abortion “increases the risk of preterm births, particularly extremely preterm deliveries;” more research is needed “to assess the differences in the level of risk according to the technique used for abortion”.

Preterm and very preterm births have been linked to health and developmental problems in infants, including cerebral palsy. 

Previous research, also conducted in Paris, revealed that the odds of a woman delivering prematurely increase with the number of abortions in her history, with the likelihood doubled in women who have had two or more abortions. Other research corroborated these findings, reporting that “the risk of preterm birth increased with the number of abortions,” according to a 2004 study.

Reduce Preterm Risk Coalition researcher Brent Rooney and Dr. Byron Calhoun revealed in 2003 that, in women with a history of four or more abortions, the risk of a future extremely early premature birth (less than 28 weeks gestation) is increased by eight times.  In addition, Rooney relates German research that revealed that a history of two abortions caused a five-fold increase in tendency to very premature babies, while three or more abortions increased the incidence to eight times the norm.  This massive 1998 study followed women in the German state of Bavaria.

Using data from a 1998 study of German women, Rooney contends that 35 percent of early preemies are in excess of what the total would be if no women had prior elective abortions. All this math means about 27,608 additional babies are born ‘early pre-term’ yearly to U.S. women, based on the estimate that 11 percent of U.S. women have had one abortion, and nine percent have had two or more abortions.

Of these 27,608 pre-term babies, roughly four percent will be born with cerebral palsy, Rooney argues. This translates to an extra 1,100 cases of children born with cerebral palsy in the U.S. annually.

Pre-term pregnancies contribute to a host of problems, including an increased risk of infant death, and as mentioned above, a significant increase in the tendency for the baby to develop cerebral palsy.

Rooney cites statistics indicating, “The cerebral palsy risk in extremely early premature birth babies is about 38 times higher than in the overall population of newborns.”

Rooney warns that the vast bulk of American women are never warned about the higher future risk of premature deliveries resulting from prior induced abortions. The only state Rooney is aware of that gives full informed consent by warning women of this danger is Texas.

[Comment: Those of us who are older remember that when abortion was illegal, it was said that abortion could cause problems with later pregnancies. That common wisdom was thrown out the window when abortion was legalized. This is why studies like this are so important to get out the truth that abortion hurts both babies and women.

THE DETRIMENTAL EFFECTS OF ADOLESCENT ABORTION, PART I  This is a 2-part article on the effects of abortion on teens.

About 20% of all abortions taking place in the USA today are performed on teens (1). Teenage abortion has been linked to a number of physical & psychological problems, including drug and alcohol abuse (2), suicide attempts and suicidal ideation (3), & other self-destructive behaviors.

Compared to women who abort at an older age, women who abort as teens are significantly more likely to report more severe emotional injuries related to their abortions (4). This finding is supported by the fact that women who aborted as teens participate in disproportionately large numbers in post-abortion counseling programs (5). In a study of post-abortive women in WEBA support groups, for example, more than 40% of the women had been teenagers at the time of their abortions (6).

THE PSYCHOLOGICAL RISKS. Compared to women who have abortions in adulthood, teens who abort:
— Are 2 to 4 times more likely to commit suicide. (7)
— Are more likely to develop psychological problems. (8)
— Are more likely to have troubled relationships. (9)
— Are generally in need of more counseling and guidance regarding abortion. (10)
— Are nearly 3 times more likely to be ad
mitted to mental health
hospitals than women in general. (11)
Studies have shown that the major factors in pregnancy decision making among teens are the attitude of the teen’s parents, the baby’s father, and her peers; the personality of the teen herself; and the cultural and public policy attitudes toward abortion by which she is surrounded (12). Compared to older women, teens are more likely to abort because of pressure from their parents or sexual partners (13), putting them at higher risk for adverse psychological effects after abortion.

Teens are also more likely to report having wanted to keep the baby, higher levels of feeling misinformed in pre-abortion counseling, less satisfaction with abortion services and greater post-abortion stress (14).  They consider the abortion procedure itself to be stressful and associated with feelings of guilt, depression and a sense of isolation (15). Researchers have also found that reports of more severe pain during abortion among younger women are linked to greater levels of anxiety and fear prior to the abortion (16).

Younger women have a more difficult time adjusting to their abortions. One study found that teenage aborters were more likely to report severe nightmares following abortion and to score higher on scales measuring antisocial traits, paranoia, drug abuse and psychotic delusions than older aborters.

Teens were also more likely to use immature coping strategies such as projection of their problems on to others, denial, or “acting out”, than older women, strategies researchers speculate might become permanent (17).

REPLACEMENT PREGNANCIES. Another study found that less than one fourth of teens were able to achieve a healthy psychological adaptive process after their abortions, and many continued to reenact their trauma through a cycle of repeat pregnancies and abortions (18).

One study found that on average, 59% of teens who had experienced a pregnancy loss generally due to induced abortion become pregnant again within 15 months (19). 

In another study, 18% of teenage abortion patients had become pregnant again within two years. (20)

Repeat pregnancies are a symptom of young women “acting out” unresolved abortion issues and the desire to “replace” the lost pregnancy with another child. Unfortunately, “replacement babies” are often aborted because the woman faces the same pressures as she did the first time, and sometimes even more. For example, a New York City study found that teens who had one previous abortion were four times more likely to abort their current pregnancy than girls experiencing their first pregnancy (21).

Another study of teen abortion in Los Angeles found that 38% of the teens had undergone an earlier abortion and 18 percent had undergone two abortions in the same year. (22)

Sometimes a teen who has been especially traumatized will choose abortion as a form of self-punishment or as an unconscious attempt to resolve her trauma by continually repeating it. In other cases, she may be hoping to continue her pregnancy but will feel pressured by her parents or partner to submit to an abortion as “what is best for everyone.” In one heart-wrenching example, a teenage girl reported that she was forced by her mother to abort four times before she was finally able to insist on keeping her fifth baby (23).

This is part II of a two-part article on the effects of abortion on teens.
The Physical Risks. Teenage abortion patients are up to twice as likely to experience cervical lacerations during abortion compared to older women(1). This increased risk is thought to be due to the fact that teens have smaller cervixes which are more difficult to dilate or grasp with instruments.

Teens are also at higher risk for post-abortion infections such as pelvic inflammatory disease (PID) and endometritis (inflammation of the uterus), which may be caused either by the spread of an undiagnosed sexually transmitted disease into the uterus during the abortion, or by micro-organisms on the surgical instruments which are inserted into the uterus(2). Researchers believe that teens may be more susceptible to infections because their bodies are not yet fully developed and do not produce pathogens that are found in the cervical mucus of ol
der women and which can protect them from infection(3).

Other studies have shown that young women who have had PID previously or who have not had a previous full-term birth are more vulnerable to post-abortion infections.(4) In addition, because teens are less likely than adults to take prescribed antibiotics or follow other regimens for the treatment of medical problems such as infection, they are at greater risk for infertility, hysterectomy, ectopic pregnancy and other serious complications(5).

Because teens are more likely to abort their first pregnancy, they face other risks as well (6). For instance, research has shown that an early full term birth can reduce a woman’s risk of breast cancer, but that induced abortion of a first pregnancy carries a 30 – 50 percent increased risk of breast cancer (7). In addition, aborting teens lose the protective effect of having a full-term pregnancy at a younger age, which would reduce the breast cancer risk.

Complications of Late-Term Abortions. The Centers for Disease Control has reported that 30% of teenage abortions occur at or after 13 weeks gestation, compared to only 12% of abortions overall(8). The high rate of late-term abortions among teens is a symptom of how they feel trapped into abortions that they cannot evade.

Women who undergo late-term abortions often delay having the abortion precisely because (a) they have mixed feelings about the decision or feel less satisfied with it, (b) they have religious or moral objections to abortion, or (c) they have a more favorable attitude toward the unborn baby than women who have abortions in the first trimester (9). Greater ambivalence about abortion increases the likelihood that women will resist advice and pressure from others to abort for a longer period of time, hoping with each passing week that more support for keeping the baby will materialize.

In this regard, polls have consistently found that more teens have pro-life or anti-abortion attitudes than do older women, which may help to explain the much higher late-term abortion rate among teens.

No doubt another factor is that teens are more likely to conceal their pregnancies, either out of shame or in an effort to avoid being pressured into an unwanted abortion. After all, many teens know well in advance that their parents or boyfriends will support only one choice – abortion.

But teens who conceal their pregnancies are never truly safe from the pressure to abort. Since abortion is legal during all nine months of pregnancy, it’s never too late for parents or others to begin pressuring a girl into an abortion once her pregnancy is discovered or revealed.

Late-term abortions, and all of the factors related to ambivalence–such as delay, concealment of the pregnancy, and feeling pressured to abort–are significantly associated with more severe emotional and psychological problems after abortion(10).

Teens who abort in the second and third trimester also face a greater risk of physical complications, including higher rates of endometritis (11), intrauterine adhesions, PID, cervical incompetence, subsequent miscarriages and ectopic pregnancies, rupture of the uterus and death(12). In addition, dilation and extraction abortions, frequently used in the second trimester, are associated with low birth weight in later pregnancies (13), which can cause various health and developmental problems for the baby, including cerebral palsy(14).

Conclusion. The pro-abortion Alan Guttmacher Institute estimates that approximately 40% of teenage abortions take place without parental involvement (15). As a result, these teens’ parents have no advance warning about the physical or emotional complications their children may experience. When the abortion causes subsequent emotional reactions that are not understood–such as depression, anger, and substance abuse–parents may react with anger and confusion, exacerbating the problems of the teen and her family. 

The cost of such concealment can be dreadfully high. Both 16-year-old Erica Richardson of Maryland and 13-year-old Dawn Ravanell of New York died from complications after they had abortions without telling their parents (16).

Sandra Kaiser, a 14-year-old St. Louis girl with a history of psychiatric problems, committed suicide three weeks after her half-sister took her for an abortion without telling Sandra’s mother (17).

Sadly, abortion advocates have continued to fight laws that could help prevent tragedies like these. The pro-abortion lobby has vigorously opposed attempts in Congress to pass legislation that would make it a federal offense for anyone to evade a state’s parental notice laws by taking a teen for an abortion in another state that does not have such laws. This legislation wouldn’t prevent all teen abortions, but at least it would protect the rights of parents and their daughters.

As shown in this brief literature review, numerous studies have found that, compared to older women, younger women–especially adolescents–are at significantly higher risk of physical and psychological complications following abortion. But this information is not generally known by the public, and certainly not by the parents who pressure their daughters into abortions.

In many of these cases, the parents truly believe they are helping to protect their daughter’s future. They have no idea that they are subjecting her to a physical and psychological trauma that will forever scar her life. Nor will the abortion clinics, who have a vested interest in keeping the dangers of abortion secret, explain the full range of risks to teenagers, their parents, or–in the case of judicial bypass–the judges who stand in the place of the parents.

Abortion is fraught with dangers and risks, especially for younger women who are at greater risk of suffering both physical and psychological complications… [The Post-Abortion Review, Vol. 9, No. 1, Jan. – March 2001; Amy R. Sobie and David C. Reardon, Ph.D.]
