Assessing the prevalence and determinants of unwanted pregnancy and induced abortion in Nigeria

This study was conducted to determine the prevalence and sociodemographic determinants of unwanted pregnancy and induced abortion in the Jos and Ife local government areas of Nigeria. A total of 1,516 randomly selected women aged 15-45 responded to a pretested structured questionnaire designed to elicit information concerning previous unwanted pregnancies and induced abortions in a value-free manner. Nearly 20 percent of the women reported having had an unwanted pregnancy. Of these, 58 percent reported that they had successfully terminated the pregnancies; 32 percent continued the pregnancies; and nearly 9 percent stated that they had attempted termination but failed. Overall, the prevalence of self-reports of induced abortion was 11 percent. The results reveal that information can be obtained on abortion in areas with restrictive abortion policies if an indirect interviewing approach is used.     

Estimating the incidence of abortion in Pakistan

This study applies an indirect estimation method to develop comprehensive national and provincial estimates of the prevalence of abortion and abortion-related morbidity in Pakistan. Data from a health facilities survey and a health professionals survey from 2002 are analyzed to develop estimates of postabortion hospitalizations and of the abortion rate, abortion ratio, and unwanted pregnancy rate. We estimate that 890,000 induced abortions are performed annually in Pakistan, and estimate an annual abortion rate of 29 per 1,000 women aged 15-49. The abortion rate is found to be higher in provinces where contraceptive use is lower and where unwanted childbearing is higher. The unwanted pregnancy rate is estimated at 77 per 1,000 women, or about 37 percent of all pregnancies. Abortions account for termination of one in seven pregnancies. An estimated 197,000 women are treated annually in public hospitals and private teaching hospitals for induced abortion complications, a number equivalent to an annual rate of 6.4 women hospitalized as a result of unsafe induced abortions per 1,000 women aged 15-49.     

Abortions in a hospital setting: hidden realities in Dar es Salaam, Tanzania.

This study investigates the extent of unwanted pregnancy, the use of illegally induced abortion, and the attitudes toward and practice of contraception among women admitted to a hospital with the diagnosis of abortion in Dar es Salaam, Tanzania. (In Tanzania, induced abortion is permitted only to save the mother's life.) A random sample of 300 women with early pregnancy loss admitted to Muhimbili Medical Centre, the teaching hospital in Dar es Salaam, were interviewed between September and November 1987, using a structured questionnaire. Among the 300 respondents, 155 said that their pregnancy had been unwanted: 94 of them presented with an illegally induced abortion and 61 with a spontaneous abortion. The number of spontaneous abortions of unwanted pregnancies increased with age and stability in a relationship. Having a small child to look after and having completed the family were the most common reasons for the pregnancy to be unwanted in this group. Induced abortion was more a problem of the young, unmarried woman. The 61 women with spontaneous abortion but unwanted pregnancy suggest that a much larger group of pregnant women continue to term with what are, at least initially, unwanted pregnancies--precisely the group of women family planning programs want to reach. The low prevalence of contraceptive use in this group indicates the failure of family planning clinics to motivate their target group. Recommendations are made for improved functioning of family planning clinics.     

Pregnancies,Abortions, and Births among Women with and without Borderline Personality Disorder

BackgroundThe purpose of this study was to examine history of pregnancies among women with and without borderline personality disorder (BPD), to determine whether BPD symptoms are associated with teenage pregnancies, unplanned pregnancies, elective and spontaneous abortions, and live births.MethodsThree hundred seventy-nine women completed the Structured Clinical Interview for DSM-IV Axis I diagnoses, Structured Interview for DSM-IV Personality for Axis II diagnoses, and a reproductive health interview. African-American (AA) women were oversampled, because little is known about BPD in AA women and they are at greater risk of teenage pregnancy, unplanned pregnancies, and spontaneous abortions.ResultsBPD symptom severity was associated with a teenage pregnancy, even after controlling for race and socioeconomic status. Symptom severity was also associated with unplanned pregnancies and live births, but only for women without a history of a substance use disorder. BPD symptom severity was not associated with abortion.ConclusionWomen with BPD become pregnant and have children, often during the period when BPD symptoms emerge and intensify. They are at increased risk of teenage pregnancies and unintended pregnancies compared with women with Axis I disorders. Treatment planning for this population should include attention to their reproductive health and better integration of physical and mental health services.     

Abortion-related maternal mortality in the Russian Federation

This study examines characteristics and determinants of maternal mortality associated with induced and spontaneous abortion in the Russian Federation. In addition to national statistical data, the study uses the original medical files of 113 women, representing 74 percent of all women known to have died after undergoing an abortion in 1999. The number of abortions and abortion-related maternal deaths fell fairly steadily during the 1991-2000 decade to levels of 56 percent and 52 percent of the 1991 base, respectively. Regional and urban-rural variation is limited. Nine percent of abortion-related maternal mortality is due to spontaneous abortion; 24 percent is related to induced abortions performed inside and 67 percent to those performed outside a medical institution. In the latter group, older women, usually with a history of several pregnancies, are overrepresented. The high rate of abortion-related maternal mortality is due largely to the number of abortions performed at 13-21 weeks' and 22-27 weeks' gestation both inside and outside medical institutions. Improving access to safe second-trimester abortion, preventing delays during the abortion procedure, and adequate treatment of complications are key strategies for reducing abortion-related maternal mortality.     

育龄女性人工流产史与妊娠等待时间的相关性研究

目的:探讨育龄女性人工流产史与妊娠等待时间(TTP)关系。方法:采用回顾性队列研究方法,将2013年1月-2017年12月参加深圳市孕前优生健康检查且符合条件的44672例育龄女性作为研究对象,以20608例既往有人工流产史者为暴露组(其中14762例有1次人工流产史,5846例有≥2次人工流产史),以24064例无人工流产史者为非暴露组。采用Kruskal-walls检验和χ2检验比较不同组间的基线特征,Kaplan-Meier法计算每个月经周期的累计妊娠率,使用Cox模型估计育龄女性人工流产史对TTP的影响。结果:既往无人工流产史的育龄女性12个月经周期的累计妊娠率为(32.6%),低于既往有1次(38.9%)和≥2次人工流产史(34.0%)者。对影响因素进行调整后,与无人工流产史的育龄女性相比,有1次和≥2次人工流产史的女性生育力分别升高19.0%(FOR=1.190,95%CI 1.147~1.234)和21.5%(FOR=1.215,95%CI 1.153~1.280)。结论:有人工流产史的育龄女性生育力较高,TTP未见延长。针对这一生育力较高的特定人群,应做好科学避孕指导工作,避免多次意外妊娠后反复实施人工流产术对其生殖健康产生不良影响。     

Risk of ectopic pregnancy and previous induced abortion.

OBJECTIVES: This study investigated the role of prior history of induced abortion in subsequent ectopic pregnancies. METHODS: Data from two French case-control studies were used to examine the effect of induced abortion on ectopic pregnancy risk. Case patients (n = 570) were women admitted for ectopic pregnancy during the study period; controls (n = 1385) were women who delivered in the same center. RESULTS: The analysis among women with no previous ectopic pregnancy showed that, after control for the main ectopic pregnancy risk factors, prior induced abortion was associated with an increased risk of ectopic pregnancy (odds ratio [OR] = 1.5, 95% confidence interval [CI] = 1.0, 2.0); there was a significant trend between number of previous induced abortions and ectopic pregnancy risk (ORs = 1.4 for 1 previous induced abortion and 1.9 for 2 or more). CONCLUSIONS: This study suggests that induced abortion may be a risk factor for ectopic pregnancy for women with no previous ectopic pregnancy, particularly in the case of women who have had several induced abortions.     

Highlights of trends in pregnancies and pregnancy rates by outcome: estimates for the United States, 1976-96.

OBJECTIVES: This report presents key findings from a comprehensive report on pregnancies and pregnancy rates for U.S. women. The study incorporates birth, abortion, and fetal loss data to compile national estimates of pregnancy rates according to a variety of characteristics including age, race, Hispanic origin, and marital status. Summary data are presented for 1976-96. Data from the National Survey of Family Growth (NSFG) are used to show information on sexual activity and contraceptive practices, as well as women's reports of pregnancy intentions. METHODS: Tabular and graphic data on pregnancy rates by demographic characteristics are presented and interpreted. Birth data are from the birth registration system for all births registered in the United States and reported by State health departments to NCHS; abortion data are from The Alan Guttmacher Institute (AGI) and the National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention (CDC); and fetal loss data are from pregnancy history information collected in the NSFG. RESULTS: In 1996 an estimated 6.24 million pregnancies resulted in 3.89 million live births, 1.37 million induced abortions, and 0.98 million fetal losses. The pregnancy rate in 1996 was 104.7 pregnancies per 1,000 women aged 15-44 years, 9 percent lower than in 1990 (115.6), and the lowest recorded since 1976 (102.7). Since 1990 rates have dropped 8 percent for live births, 16 percent for induced abortions, and 4 percent for fetal losses. The teenage pregnancy rate has declined considerably in the 1990's, falling 15 percent from its 1991 high of 116.5 per 1,000 women aged 15-19 to 98.7 in 1996. Among the factors accounting for this decline are decreased sexual activity, increases in condom use, and the adoption of the injectable and implant contraceptives.     

Abortion risk and decisionmaking among young people in urban Cameroon

This study examines the use of induced abortion among Cameroonian adolescents and young women, based on biographical data collected in 1997 among young women and men residing in Yaoundé. Results suggest a high prevalence of abortion during adolescence and early adulthood (35 percent of all pregnancies reported). Although most clandestine abortions were performed by a physician or a nurse, the prevalence of abortion performed by nonmedical personnel or using unsafe methods is still high, and postabortion health complications are reported for about one-fourth of all abortions. Logistic regression models are used to examine the effect of women's, partners', and relationships' characteristics at the time of pregnancy on the odds that a pregnancy will be terminated through abortion. The analysis shows a significant effect of school enrollment, parity, and stability and social acknowledgment of the sexual relationship on the risk of having an abortion. Young men's involvement in decisions and their motivations concerning abortion are also examined.     

The social constructions of unwanted pregnancy and abortion in Lima, Peru

Although modern contraceptive use in Peru has increased, many women still face unwanted or unplanned pregnancies and abortions remain high despite the illegality of elective pregnancy termination. To improve understanding of how men and women make reproductive decisions, we conducted this study in Lima. Fifty-two 18-37 year old low- and middle-income women and men participated in in-depth interviews and focus groups. Reproductive planning constitutes a worry among participants. The paradigm of contraception, pregnancy, childbearing and pregnancy termination is complex and contained within a context of contradictory pressures toward women: while women feel the need to be autonomous in all realms of their lives, they also need to meet the traditional roles associated with sexuality and childbearing and rearing. The woman, her partner and family members take part in reproductive decisions. However, participants expressed difficulties preventing unwanted pregnancies and social stigma if they resorted to abortion or, interestingly, if they continued a pregnancy when involved in a socially undesirable personal situation. Abortion-related stigma generated fear and guilt in addition to safety concerns given the unsafe, clandestine contexts in which pregnancy termination takes place. Despite these concerns, interviewees often opted for abortion for personal reasons, which were primarily economic.     

Medically indigent women seeking abortion prior to legalization: New York City, 1969-1970.

If the efforts now underway to limit access to abortion services in the United States are successful, their greatest impact will be on women who lack the funds to obtain abortions elsewhere. There is little published information, however, about the experience of medically indigent women who sought abortions under the old, restrictive state laws. This article details the psychiatric evaluation of 199 women requesting a therapeutic abortion at a large municipal hospital in New York City under a restrictive abortion law. Thirty-nine percent had tried to abort the pregnancy. Fifty-seven percent had concrete evidence of serious psychiatric disorder. Forty-eight percent had been traumatized by severe family disruption, gross emotional deprivation or abuse during childhood. Seventy-nine percent lacked emotional support from the man responsible for the pregnancy, and the majority were experiencing overwhelming stress from the interplay of multiple problems exacerbated by their unwanted pregnancy.     

Induced abortion and the risk of subsequent ectopic pregnancy.

This study assessed the effect of legal induced abortion on ectopic pregnancy risk by using a comparison group of reproductive-age women who were at risk of becoming pregnant during the same time period the women with ectopic pregnancy conceived. Cases were members of Group Health Cooperative of Puget Sound who were hospitalized for ectopic pregnancy from October 1981 through September 1986 (N = 211). Controls were randomly selected members matched to cases on age and county of residence (N = 457). All subjects in this analysis had had one or more prior pregnancies. Eighty-eight cases (41.7 per cent) and 177 controls (38.7 per cent) had a history of one or more induced abortions. The relative risk of ectopic pregnancy associated with one abortion was 0.9 (95 per cent confidence interval 0.6, 1.3), adjusted for age, county, reference date, religion, gravidity, age at first pregnancy, lifetime number of sexual partners, and miscarriage history. Among women with two or more prior pregnancies, the risk associated with two or more abortions was 1.2 (0.6, 2.4). Controlling for pelvic inflammatory disease and use of intrauterine devices did not alter these risks. We conclude that legal abortion as performed in the US since 1970 has little or no influence on a woman's risk of ectopic pregnancy in subsequent pregnancies.     

Child-bearing after induced abortion: reassessment of risk.

We reviewed 1791 singleton pregnancies of women with a history of previous induced abortion and compared them with 14,857 pregnancies in mothers with no previous induced abortions. Therapeutic termination of pregnancy was associated with a statistically significant increase in the incidence of low birth weight infants and bleeding in the first trimester of pregnancy. When other variables were examined, no significant differences were found between the two groups, except for a significantly higher rate of stillbirths among women who had not had a prior induced abortion. There were no increases in major or minor congenital malformations.     

Estimating the probability of spontaneous abortion in the presence of induced abortion and vice versa.

An integrated approach to estimate the total number of pregnancies that begin in a population during one calendar year and the probability of spontaneous abortion is described. This includes an indirect estimate of the number of pregnancies that result in spontaneous abortions. The method simultaneously takes into account the proportion of induced abortions that are censored by spontaneous abortions and vice versa in order to estimate the true annual number of spontaneous and induced abortions for a population. It also estimates the proportion of pregnancies that women intended to allow to continue to a live birth. The proposed indirect approach derives adjustment factors to make indirect estimates by combining vital statistics information on gestational age at induced abortion (from the 12 States that report to the National Center for Health Statistics) with a life table of spontaneous abortion probabilities. The adjustment factors are applied to data on induced abortions from the Alan Guttmacher Institute Abortion Provider Survey and data on births from U.S. vital statistics. For the United States in 1980 the probability of a spontaneous abortion is 19 percent, given the presence of induced abortion. Once the effects of spontaneous abortion are discounted, women in 1980 intended to allow 73 percent of their pregnancies to proceed to a live birth. One medical benefit to a population practicing induced abortion is that induced abortions avert some spontaneous abortions, leading to a lower mean gestational duration at the time of spontaneous abortion.     

Immediate Post-Abortion Insertion of Intrauterine Contraceptives (IUC) in a Diverse Urban Population

Ethnic minority women have a higher incidence of unintended pregnancy and abortion than Caucasian women, with significant individual and social implications. Post-abortion intrauterine contraceptive (IUC) use may reduce future unintended pregnancy. This was a retrospective review of 265 women undergoing abortion at a Los Angeles County Reproductive Options Clinic. Demographic factors, reproductive history, and post-abortion contraceptive choice were evaluated and analyzed. The population was predominantly Latina (73 %) and single, with a mean age of 27. Immediate post-abortion IUC insertion was chosen by 48 % overall and more frequently by Latinas (55 %) than by African Americans (33 %) or Asians (43 %) (p = 0.02). IUC use increased with age, undesired future fertility, increasing gravidity, and history of previous abortion in univariate analysis. In multivariate analysis, IUC use increased with Latina ethnicity and increasing gravidity. In a clinic serving low-income urban women in Los Angeles, post-abortal IUC uptake is highest among Latinas and those with prior pregnancies. Future research should examine reasons for and barriers to IUC uptake in diverse communities and methods to improve post-abortion IUC uptake to prevent subsequent unintended pregnancies.     

Pregnancy outcomes after removal of osmotic dilators in patients who presented for second-trimester abortion

ObjectiveThe objective was to report pregnancy outcomes and potentially related complications among 13 patients who had osmotic dilators placed for second-trimester dilation and evacuation (D&E) followed by subsequent removal with the intention to continue their pregnancies.Study designWe reviewed billing and scheduling data between 2005 and 2017 to identify the total number of women seen for D&E and to identify the individuals who had dilators placed without a subsequent scheduled dilation and evacuation. We then performed chart reviews to determine pregnancy outcomes.ResultsBetween 2005 and 2017, we treated 2532 patients who presented for second-trimester abortions by D&E and received osmotic dilators for cervical preparation. Twenty (0.8%) of these women had cervical dilators removed with the intention of continuing their pregnancies. We could obtain outcome data for 13 of these pregnancies; one of these women ultimately elected to have an abortion. Eight of the remaining 12 women (66%) experienced complications which included premature preterm rupture of membranes, preterm delivery, maternal infection and hemorrhage. Six (50%) pregnancies ended in spontaneous abortion or fetal or neonatal death.ConclusionContinuation of pregnancy after placement and removal of osmotic dilators may increase the risk of adverse pregnancy outcomes.ImplicationsOf the women who had outcome data available, 50% who had cervical dilators removed experienced spontaneous abortion or fetal or neonatal death. Conservatively assuming that all women lost to follow-up had healthy pregnancies, 30% of women experienced fetal or neonatal death and 40% had an adverse pregnancy outcome.     

Abortion, contraceptive use, and adolescent pregnancy among first-year medical students at a major public university in Mexico City.

OBJECTIVE: If properly trained, medical students could become future opinion leaders in health policy and could help the public to understand the consequences of unwanted pregnancies and of abortions. The objective of this study was to analyze the frequency of unwanted pregnancies and induced abortions that had occurred among women who were first-year medical students at a major public university in Mexico City and to compare the experiences of those women with the experiences of the general population of Mexican females aged 15 to 24. METHODS: In 1998 we administered a cross-sectional survey to all the first-year medical students at the National Autonomous University of Mexico, which is the largest university in Latin America. For this study we analyzed 549 surveys completed by female students. RESULTS: Out of the 549 women, 120 of them (22%) had been sexually active at some point. Among those 120 sexually active students, 100 of them (83%) had used a contraceptive method at some time, and 19 of the 120 (16%) had been pregnant. Of those 19 women who had been pregnant, 10 of them had had an illegal induced abortion (in Mexico, abortions are illegal except under a small number of extenuating circumstances). The reported abortion rate among the female medical students, 2%, was very low in comparison with the 11% rate for women of similar ages in the Mexican general population. CONCLUSIONS: The lower incidence of abortion among the female medical students indicates that when young Mexican women have access to medical information and are highly motivated to avoid unintended pregnancy and abortion, they can do so.     

Exploratory spatial data analysis for the identification of risk factors to birth defects

Background

Nearly 10% of the population of Turkey lives in the Southeast Anatolian Project (SEAP) region. The population growth rate and the rate of unintended pregnancies are high and family planning services are insufficient in this region. Lifetime induced abortion rate is also high in this region. Public health problems of the SEAP region were investigated in the "SEAP Public Health Project" in 2001 and 2002. As it is one of the most important health problems of the women living in this region; induced abortion was also investigated in this project.

Methods

An optimumsample size representing the rural and urban area of the region (n = 1150) was chosen by the State Institute of Statistics by a sampling method proportional to size. 1126 of the area's 1150 houses have been visited and data about induced abortions have been obtained by applying a questionnaire to 1491 ever married women who live in the region.

Results

It has been found that 9.0% of these women who had at least one pregnancy in their life had at least one induced abortion. The lifetime induced abortion per 100 pregnancies was found to be 2.45. The primary reason given for induced abortions was "wanting no more children" (64.6%). Lifetime induced abortions were 5.3 times greater with women using a family planning method than women not using family planning methods. Lifetime induced abortions were 4.1 times greater with unemployed women than working women. Most of the women have used private doctors in order to have an induced abortion. Although 32.29% have not yet begun to use a contraceptive method after their last induced abortion, 43.75% of the women have since started to use an effective contraceptive method. 23.96% of them have begun to use an ineffective contraceptive method.

Conclusions

Induced abortion is still an important problem at the SEAP region. The results of the study remind us that unemployed women and women who have more than four children is our target group in the campaign against induced abortions. Most of the women use private doctors in order to have an induced abortion. Thus, priority must be given to educate private gynecologists with respect to induced abortion. After induced abortions, a qualified family planning consultant can be given to women and they can be secured to use a suitable contraceptive method.     

Safety of MenACWY-CRM vaccine exposure during pregnancy

BackgroundAlthough the meningococcal conjugate MenACWY-CRM vaccine is not approved for use in pregnant women, unintentional exposure during pregnancy can occur, especially during early pregnancy among women of child-bearing age. This study provides safety information about inadvertent MenACWY-CRM vaccination during pregnancy.MethodsThe evaluated population consisted of pregnant female members of Kaiser Permanente Southern California who inadvertently received MenACWY-CRM at 11–21 years of age during 09/30/2011-06/30/2013 within 28 days prior to conception or during pregnancy. Chart abstraction was conducted to identify pregnancy and birth outcomes, including spontaneous and induced abortions, preterm births, low weight births, and major congenital malformations (MCMs).ResultsThere were 92 women who received MenACWY-CRM during the pregnancy exposure period, mainly during the first trimester (76.1%). Hispanics represented the largest race/ethnicity category (68.5%). Among the known pregnancy outcomes (n = 66; excluding induced abortions and unknown pregnancy outcomes), the prevalence of spontaneous abortions was 18.2% (n = 12). Among live born infants (n = 55; from 54 pregnancies), 14.5% (n = 8) were born preterm (<37 weeks gestation) and 9.1% (n = 5) had a low birthweight (<2500 g). The prevalence rate of MCMs among live born infants (n = 55) was 1.8% (n = 1).ConclusionsThis study provides baseline prevalence estimates of spontaneous abortions, preterm births, low weight births, and MCMs among women inadvertently exposed to MenACWY-CRM during the pregnancy period. These estimates appear to be comparable with U.S. background prevalence estimates.
