A study of contraception as related to unwanted pregnancy

A study was made of 150 women requesting therapeutic abortion. Mechanical failure of the contraceptive method used accounted for unwanted pregnancy in 89 (59%) women. In the remainder no method of contraception was used by either partner. Among women requesting abortion, failure to use contraceptives was commoner in the younger and unmarried than in older and married women.The data obtained were analyzed in an attempt to explain the failure and avoidance of contraception. Suggestions are made as to how to discourage the use of abortion as a method of contraception.     

Abortion-seeking behaviour among Nigerian women

This study used data from a community-based survey to examine women's experiences of abortion in Nigeria. Fourteen percent of respondents reported that they had ever tried to terminate a pregnancy, and 10% had obtained an abortion. The majority of women who sought an abortion did so early in the pregnancy. Forty-two percent of women who obtained an abortion used the services of a non-professional provider, a quarter experienced complications and 9% sought treatment for complications from their abortions. Roughly half of the women who obtained an abortion used a method other than D&C or MVA. The abortion prevalence and conditions under which women sought abortions varied by women's socio-demographic characteristics. Because abortion is illegal in Nigeria except to save the woman's life, many women take significant risks to terminate unwanted pregnancies. Reducing the incidence of unwanted pregnancy and unsafe abortion can significantly impact the reproductive health of women in Nigeria.     

Elevated viral antibody titres in spontaneous abortion

To assess the possible role of virus infections in spontaneous abortion we undertook a prospective study of three groups of patients: women who had a spontaneous abortion; women seen in the antenatal booking clinic; and those undergoing therapeutic termination of pregnancy. Venous blood was taken for antibody detection, cervical swabs for virus isolation, and in the cases of spontaneous and therapeutic abortion products of conception were sent for virus culture. The infectious agents studied were influenza A and B, adenovirus, respiratory syncytial virus, measles, psittacosis, Varicella zoster, and mumps virus. Statistical analysis revealed that women in the spontaneous abortion group has a higher incidence of antibodies against respiratory syncytial virus (P less than 0.01), and mumps virus (P less than 0.01). Among women seropositive for each virus, higher titres were found only for respiratory syncytial virus (P less than 0.05) in cases rather than controls. These results could be explained if viruses such as respiratory syncytial virus caused abortion or if women having a spontaneous abortion mount exaggerated immune responses to fetal and viral infections, and the former altered immune response is associated with spontaneous abortion.

The infectious agents studied were influenza A and B, adenovirus, respiratory syncytial virus, measles, psittacosis, Varicella zoster , and mumps virus. Statistical analysis revealed that women in the spontaneous abortion group has a higher incidence of antibodies against respiratory syncytial virus ( P <0.01), and mumps virus ( P <0.01). Among women seropositive for each virus, higher titres were found only for respiratory syncytial virus ( P <0.05) in cases rather than controls.

Properties of chromatin of peripheral blood lymphocytes in women with threatened abortion

The authors studied the properties of peripheral blood lymphocyte chromatin from donors (non-pregnant women), from women with normal pregnancy and during threatened abortion. Using three independent cytochemical methods that characterize the DNA accessibility for acridine orange and 3H-actinomycin D and the presence in histones of free amino groups, it has been established that lymphocyte chromatin from women during threatened abortion is repressed to a greater degree than in those with normal pregnancy. The data presented demonstrate the prospectiveness of the use of the cytochemical tests for chromatin properties with a purpose of diagnosing whether the pregnancy will be full-term and treatment control.     

Abortion experience among obstetric patients at Korle-Bu Hospital, Accra, Ghana

Hospital admissions for complications of abortion have been increasing in Africa, indicating a rise in the incidence of abortion. In all pregnant women ever admitted to Korle-Bu hospital in Accra, Ghana, the chance that the outcome of their last pregnancy was an induced abortion decreased as the number of previous pregnancies increased. Women with higher levels of education were more likely to have their 1st pregnancy terminated in an induced abortion. Younger women were more likely than older women at each level of education to have an induced abortion terminate a 1st pregnancy. The use of contraceptives during the last pregnancy interval increased with the level of education of the woman and the number of previous pregnancies. Contraceptive use was also highest among women whose last pregnancy outcome was an induced abortion. The mean pregnancy interval decreased with increasing number of previous pregnancies for both women who used and who did not use contraceptives during their last pregnancy interval. But the mean pregnancy interval was higher among women who used contraceptives. It appears that the abortion experience in this region of Africa is most common in lower parity young women with high levels of education who desire to delay a 1st birth or to space births. This is in contrast in Latin America and other developing countries in which abortion is used mainly by older, married, urban women to limit family size. Contraceptive use in this region of Africa is low, indicating the need for more family planning programs and increasing use of existing programs.     

Suicides after pregnancy in Finland, 1987-94: register linkage study.

OBJECTIVE: To determine rates of suicide associated with pregnancy by the type of pregnancy. DESIGN: Register linkage study. Information on suicides in women of reproductive age was linked with the Finnish birth, abortion, and hospital discharge registers to find out how many women who committed suicide had had a completed pregnancy during her last year of life. SETTING: Nationwide data from Finland. SUBJECTS: Women who committed suicide in 1987-94. RESULTS: There were 73 suicides associated with pregnancy, representing 5.4% of all suicides in women in this age group. The mean annual suicide rate was 11.3 per 100,000. The suicide rate associated with birth was significantly lower (5.9) and the rates associated with miscarriage (18.1) and induced abortion (34.7) were significantly higher than in the population. The risk associated with birth was higher among teenagers and that associated with abortion was increased in all age groups. Women who had committed a suicide tended to come from lower social classes and were more likely to be unmarried than other women who had had a completed pregnancy. CONCLUSIONS: The increased risk of suicide after an induced abortion indicates either common risk factors for both or harmful effects of induced abortion on mental health.     

CRIMINAL ABORTION—A Consideration of Ways to Reduce Incidence

The problem of criminal abortion in the United States is of enormous magnitude, both in terms of incidence and of resultant morbidity and mortality. Several studies suggest that one of every five pregnancies terminates in criminal abortion, or a total of more than one million abortions for 1960, with a possibility of more than 5,000 deaths resulting therefrom.The inadequate laws regarding therapeutic abortion in most jurisdictions contribute much to the problem. Tracing the origins of these laws provides additional clues concerning the development of this enigma.Suggested answers to the problem include: (1) Broadening and clarifying therapeutic abortion laws to reflect current medical practice, yet provide stringent controls; (2) prevention of unwanted pregnancy through consultation centers for women, encouragement of contraceptive research and education of the public.     

Deconstructing Pregnancy: RU486, Seeing "Eggs," and the Ambiguity of Very Early Conceptions

This article deconstructs previous notions of pregnancy. Using empirical data from French women's experience with RU486 for medical abortion, I demonstrate that very early and unwanted conceptions have an ambiguous quality. I illustrate an understanding of pregnancy as a reproductive continuum: these women understand pregnancy to include a stage where "eggs," and not fetuses, are present. I discuss how the use of RU486 creates new ways of knowing about the fetus, and I compare an understanding of the fetus by women using RU486 with previous understandings from ultrasound images, in utero photography, and the imagination. I demonstrate that women's embodied knowledge can expand the parameters of fetal discourse. [RU486, fetal discourse, embodied knowledge, abortion, reproductive technology]     

Influence of past reproductive performance on risk of spontaneous abortion.

OBJECTIVE--To investigate the incidence of spontaneous abortion in a population of women in order to establish their risk of spontaneous abortion and the obstetric factors predisposing to it. DESIGN--Prospective study of women recruited by radio and poster appeal and from hospital outpatient clinics. SETTING--English provincial community. PATIENTS--630 Women from the general population intending to become pregnant. INTERVENTIONS--The viability of the pregnancy was assessed by abdominal ultrasonography before completion of the eighth week, and the assessment was repeated if vaginal bleeding occurred. MAIN OUTCOME MEASURE--Spontaneous abortion or live births in women with or without a previous history of spontaneous abortion. RESULTS--The overall incidence of clinically recognisable spontaneous abortion before 20 weeks of gestation was 12% (50/407 pregnancies). The risk of spontaneous abortion in each category of patient was classified with respect to the patient''s past reproductive performance and found to be influenced greatly by her previous obstetric history. In primigravidas and women with a history of consistently successful pregnancies the incidences of abortion were low (5% (4/87) and 4% (3/73) respectively), whereas women with only unsuccessful histories had a much greater risk of aborting the study pregnancy (24% (24/98)), even when their sole pregnancy had ended in abortion (20% (12/59)). The outcome of the last pregnancy also influenced the outcome of the study pregnancy; only 5% of women (5/95) whose previous pregnancy had been successful aborted, whereas the incidence of loss of pregnancy among women whose last pregnancy had aborted was 19% (40/214). CONCLUSIONS--A knowledge of the patient''s reproductive history is essential for the clinical assessment of her risk of spontaneous abortion. As the most important predictive factor for spontaneous abortion is a previous abortion, the outcome of a woman''s first pregnancy has profound consequences for all subsequent pregnancies.

Lifetime Induced Abortion: A Comparison between Women Living and Not Living with HIV

Background

Studies aimed at understanding the association between induced abortion and HIV are scarce and differ on the direction of the association. This paper aims to show the prevalence of induced abortion in a sample of pregnancies of women living and not living with HIV/Aids, determining variables associated with pregnancy termination and linked to the life course of women and to the specific context of the pregnancy.

Methods

Data came from a cross-sectional study, using interviewer-administered questionnaire, developed with women that attended public health services in Porto Alegre, Brazil. A generalized estimating equation model with logit link measured the association between determinants and abortion.

Findings

The final sample was composed of 684 women living with HIV/Aids (2,039 pregnancies) and 639 women not living with HIV/Aids (1,539 pregnancies). The prevalence of induced abortion among pregnancies in women living with HIV/Aids was 6.5%, while in women not living with HIV/Aids was 2.9%. Among women living with HIV/Aids, the following were associated with induced abortion in the multivariable analysis: being older, having a higher education level, having had more sexual partners (i.e., variables linked to the life course of women), having had children prior to the index pregnancy and living with a sexual partner during pregnancy (i.e., variables linked to the context of each pregnancy). On the other hand, among women not living with HIV/Aids, only having a higher education level and having had more sexual partners (i.e., determinants linked to the life course of women) were associated with voluntary pregnancy termination in multivariable analysis.

Conclusion

Although determinants are similar between women living and not living with HIV/Aids, prevalence of induced abortion is higher among pregnancies in women living with HIV/Aids, pointing to their greater social vulnerability and to the need for public policy to address prevention and treatment of HIV associated with reproductive issues.     

Requests for late termination of pregnancy: Tower Hamlets, 1983.

The case histories of all women seeking late (more than 20 weeks'' gestation) abortion in the NHS district of Tower Hamlets in 1983 were assessed. Of 12 women requesting late abortion, seven underwent termination of pregnancy. All the women had severe social or psychological problems, or both. The main reasons for late presentation were denial of pregnancy, youth, and mental disorder. In a small group of atypical women late abortion seems to be justified for reasons other than fetal abnormality.

Why is the number of pregnancies among teenagers decreasing?

The issue of pregnancy among adolescent women has received considerable attention from the media. Contrary to common belief, both the numbers and the rates of such pregnancies, even when data on abortion are included, have been declining. Patterns of contraception may account for some of the decrease; however, more study is required. In the past, unmarried teenagers who became pregnant either got married or put the baby up for adoption. Now they can either have an abortion or keep the baby. Solutions to the problems of pregnancy among teenagers must therefore be addressed to these altered social consequences rather than to misleading comments about "epidemics", with their suggestion of increased rates of pregnancy.     

Determination of selected coagulation parameters in induced abortion by means of 15-methyl-PGF2 alpha]

There were accomplished investigations about changes of bleeding and recalcification time, platelet count, levels of heat-fibrin, prothrombin, partial thromboplastin time, platelet adhesiveness and heparinocytes at 10 women during induction of therapeutic abortion by use of intramuscular injections of 15-methyl-PGF2 alpha in the first and second trimester of pregnancy. The studies were performed before treatment, 30 minutes, 4 and 8 hours after beginning 15-methyl-PGF2 alpha-administration, 2 hours after expulsion of product of conception and 24 hours after first injection. The following investigations showed statistical significant changes: Prothrombin decreased during treatment with 15-methyl-PGF2 alpha and did not obtain the starting value 24 hours after first injection. Platelet count showed an equal attitude. The heparinocytes showed a continuous falling off up to 2 hours after termination the pregnancy. A significant ascent was noticed 24 hours after first investigation. The results of studies did not indicate a strong injury of coagulation system. They support the positive estimate for induction of therapeutic abortion with 15-methyl-PGF2 alpha in the first and second trimester of pregnancy.     

Outpatient Termination of Early Pregnancies Using Syringe and Plastic Cannula

Using a 50 ml syringe and a Karman-type cannula-curette, outpatient therapeutic abortions were done in 543 women who were not more than eight weeks pregnant. All patients received paracervical block analgesia and atropine was given intravenously to minimize vagal reactions. In five women (0.9 percent) pregnancies were missed by the procedure, and in 13 women (2.4 percent) abortions were incomplete. In only one patient did a significant postoperative pelvic infection occur. Twenty-seven women (4.9 percent) were not pregnant; the initiation of routine urine pregnancy testing reduced the percentage of those who were nongravid. The procedure using syringe and plastic cannula is safe, well tolerated and has reduced therapeutic abortion costs.
