Induced abortion is illegal in Nigeria except when performed to save a woman’s life. Both the penal code, which is generally applied in the country’s northern states, and the criminal code, which generally applies in the southern states, allow this exception, and both regions specify similar criminal penalties for noncompliance.1 Yet pregnancy terminations are quite common, and because they are often performed clandestinely or by unskilled providers, most are unsafe.2 The first national study to examine the incidence of abortion estimated that in 1996, about 610,000 abortions, or 25 per 1,000 women aged 15–44, occurred in Nigeria.3 A decade later, another study noted that if the abortion rate had not changed since 1996, then 760,000 abortions would have occurred in 2006, given the increase in Nigeria’s population during this period.4
Since the release of the 1996 estimates, the Nigerian government and other stakeholders have initiated a number of policies and programs to improve the reproductive health of women in the country. Notable among them are the government’s efforts to achieve the United Nations Millennium Development Goals, including Goal 5, to improve maternal health. This goal has two targets: to reduce the maternal mortality ratio by 75% between 1990 and 2015, and to provide universal access to reproductive health by 2015. A 2010 government report concluded that progress toward achieving these targets has been slow, and that the modest progress that has been made in reducing maternal mortality has not been accompanied by improvements in other indicators, such as family planning uptake and the proportion of births attended by skilled health workers.5
In the hopes of better understanding the scale of clandestine abortion and related reproductive health issues facing Nigerian women, we present new estimates of the incidence of induced abortion in Nigeria, at the national level and for each of the country’s six geopolitical zones.
We produced our estimates using the Abortion Incidence Complications Methodology (AICM), an indirect approach that has been used to estimate the incidence of abortion in more than 15 countries.6–9 The methodology relies on data collected through two surveys: a Health Facilities Survey, which gathers information from facilities that treat postabortion patients (i.e., women with complications from induced or spontaneous abortions), and a Health Professionals Survey, which collects information about abortion provision from knowledgeable key informants. These surveys are described in detail below. In addition, we used fertility and other data from the 2013 Nigeria Demographic and Health Survey (NDHS)10 and population estimates from the United Nation’s 2012 revision of the World Population Prospects in our calculations.11 The study was approved by the Guttmacher Institute’s institutional review board and by the University of Ibadan Ethical Review Committee.
Health Facilities Survey
All public and private health facilities that had the capacity to provide postabortion care services were included in the sample frame for the survey. We compiled a list of potentially eligible health facilities using the most recent (2007) National Bureau of Statistics’ Directory of Health Establishments in Nigeria, supplemented by information from the 2007 National Health Insurance Scheme and the Ministry of Health’s Department of Hospital Services. Slightly more than 5,000 facilities were deemed eligible.
It was important to represent all six of Nigeria’s geo-political zones, because women’s social and demographic characteristics vary greatly across the country, particularly between the northern and southern zones.* Therefore, using information from the Nigerian census and the 2008 NDHS,† we grouped the states in each zone into tertiles according to the proportion of women who lived in urban areas, and randomly selected one state per tertile (and thus three states per zone). This yielded a total of 18 states across the country: Kaduna, Kebbi and Jigawa in the North West; Bauchi, Borno and Taraba in the North East; Kwara, Nasarawa and Niger in the North Central; Abia, Anambra and Imo in the South East; Cross River, Edo and Rivers in the South South; and Lagos, Ogun and Ondo in the South West.
A total of 3,125 facilities that potentially provided post-abortion care were located in the 18 states. We randomly selected 75% of public secondary hospitals (general, specialist and district-level), comprehensive health centers, cottage hospitals and public clinics; 40% of private hospitals, clinics and medical centers (a mixture of secondary- and primary-level facilities); 40% of public maternity centers (mostly primary-level); and 17% of private maternity centers (again, mostly primary-level). In addition, because of their large postabortion care caseload, we included all tertiary facilities (teaching hospitals and federal medical centers) in the country, regardless of whether they were located in sampled states. After exclusion of 45 facilities that no longer existed or were not found, the final sample consisted of 1,088 facilities.
Trained interviewers visited each sampled facility between July 2011 and March 2012, and used a standardized questionnaire to conduct a face-to-face interview with a senior staff member knowledgeable about the facility’s provision of abortion services. Respondents were chosen on the basis of their seniority as well as their familiarity with abortion-related services at their facility; they either oversaw abortion or postabortion care at the facility, or were the only provider or one of the few providers of such services. Interviewers, with the support of their supervisors, were responsible for using these criteria to locate appropriate respondents. In some instances, the identified respondent was unavailable or was unable to complete an interview. In these cases, the interviewer made multiple attempts to interview the respondent; if this was not possible, the interviewer sought an interview with the next most knowledgeable person, if there was more than one provider.
The response rate for the survey was 98%. An initial analysis found that 314 facilities in our sample did not offer postabortion care, and two that did offer such services had not responded to a number of key questions; these facilities were removed from our analysis. Of the remaining 772 facilities, 48% were in the public sector, and 52% were private or were operated by nongovernmental organizations or missions (Table 1). For each geographic zone, we assumed that the proportion of facilities in our sample that did not provide postabortion care was representative of the zone as a whole, and proportionally reduced the universe of facilities that provide such services in the zone, resulting in an estimate that 3,879 facilities provide post-abortion care nationally.
Most of the facilities included in this study provided both inpatient and outpatient services (Appendix Table 1). The majority of high-level government facilities (teaching hospitals, federal medical centers, and general and specialist hospitals) and private facilities had functional manual vacuum aspiration (MVA) equipment; the proportion ranged from 62% for private maternity centers to 98% for teaching hospitals and federal medical centers. Fifty percent of cottage hospitals and other community health centers had functioning MVA equipment, but only 10% of government maternity facilities did. With the exception of government maternity centers, the majority of facilities in each category had staff trained in use of the equipment. All teaching hospitals, federal medical centers, and general and specialist hospitals had surgical wards, as did more than 90% of private hospitals, clinics and medical centers. Most teaching hospitals and federal medical centers (84%) also reported having a separate ward for abortion-related services.
Because of staff shortages and inadequate resources, record-keeping is inadequate at facilities in many developing countries. For example, a recent study found medical record-keeping in six tertiary facilities in Nigeria to be poor in both completeness and quality,12 and only 46% of sampled facilities in a 2008 Colombian AICM study were able to provide adequate information for the study year, leading the authors to argue that “data maintained by facilities are currently too incomplete to be the basis of national estimates of abortion incidence.”13 Because we had similar concerns, we did not rely on official facility records to help us determine the number of postabortion care cases or pregnancy terminations at the facility. Instead, we obtained caseload estimates for each facility from the knowledgeable senior staff member who was interviewed for the survey.
Of the 772 surveyed respondents, 52% were obstetrician/gynecologists, general practitioners, other physicians or medical officers; 33% were nurses or midwives; 14% were community health extension workers or community health officers; and fewer than 1% were other staff (Appendix Table 2). Fifty-seven percent of respondents had at least 10 years of work experience, 41% were female and 70% were aged 30–50 (not shown). In public teaching hospitals and federal medical centers, and in private hospitals, clinics and medical centers, a large majority of respondents were physicians or medical officers (66–72%; Appendix Table 3), while in public cottage hospitals, comprehensive health centers and public clinics most respondents were nurses, midwives, community health extension workers or community health officers (74–93%). General and specialist hospitals and private maternity centers had a more balanced mix of respondents.
All respondents provided informed consent; they did not receive remuneration for participating. Respondents were asked to estimate the number of patients who received postabortion care (for complications of either spontaneous or induced abortion) at their facility as outpatients and inpatients. To accommodate the large variation in facility size and capacity, we offered respondents three time periods (week, month and year) for which to make their estimates, but asked them to answer for only one. They provided estimates for both the average week, month or year, and the past week, month or year. We asked for these two types of estimates to increase the likelihood of accurate recall and of capturing variation within the year. Responses were converted to annual totals and averaged to provide an estimate for the calendar year. Respondents were also asked to estimate the number of induced abortions performed at the facility during the same time periods.
In examining the data from the Health Facilities Survey, we became concerned about the accuracy of some results, because the proportion of facilities that reported providing abortions was very small, regardless of facility type. In the Health Facilities Survey conducted for the 1996 estimate of abortions incidence in Nigeria, 33% of respondents indicated that their facility provided induced abortion services;3 in the current study, only 8% of respondents reported that their facility performed abortions (Appendix Table 1). Private clinics and medical centers were the most likely to report providing this service (21%), followed by teaching hospitals and federal medical centers (14%).
We hypothesized that because of growing social conservatism throughout Nigeria and the inhibiting effects of a new antiabortion stance in the national (and a number of state) legislative houses, some respondents were misclassifying pregnancy terminations—probably intentionally—as cases of postabortion care. The defeat of the 2006 reproductive health bill in the Senate (largely because it was considered an abortion bill), and the 2013 repeal of a 2012 law that, among other things, had expanded the criteria for legal abortion in Imo state, exemplify the increasing level of social conservatism in Nigeria.14 Moreover, in a 2009 study, nearly one-third of 49 Nigerian policymakers surveyed said that abortion should not be allowed even to save a woman’s life.15 Because our respondents’ apparent misreporting of the number of abortions performed at their facility would have resulted in our overestimating the number of postabortion care patients treated in Nigeria, we adjusted their estimates in accordance with our experience from a similar study we had conducted (see Appendix).
Health Professionals Survey
The Health Professionals Survey was designed to elicit respondents’ perceptions regarding various aspects of abortion provision in Nigeria and the potential health consequences of such abortions; topics included the types of providers from whom women obtain abortions, the likelihood that these abortions result in complications and the likelihood that women obtain treatment at a facility for these complications. Study investigators and the research team prepared a list of health professionals knowledgeable about the conditions of abortion provision and postabortion care. Interviewers and supervisors from each geopolitical zone contributed to the list, ensuring adequate representation of all zones. We drew on membership directories of relevant professional associations to further broaden the list; we intentionally avoided selecting individuals who had participated in the Health Facilities Survey.
The resulting purposive sample of 194 respondents spanned a wide range of professions, including doctors, nurses and midwives (54%); program managers and health administrators (12%); policymakers, legal practitioners and activists (16%); lecturers and researchers (15%); and other experts (4%; Appendix Table 2). We included both medical and nonmedical participants because evidence indicates that estimates of the parameters under investigation may differ substantially between these two groups.6 The representation of medical providers varied from 44% in the South South region to 67% in the South East. About 54% of the sample was from the north, 75% were working in the public sector and 43% either were currently working in rural areas or had done so in the past five years (not shown). All interviews were conducted in person by a small number of trained interviewers using a structured questionnaire.
The first step of our analysis was to estimate the number of women who receive treatment for induced abortion complications in Nigeria’s health facilities. Health Facilities Survey respondents were not asked to provide separate estimates for induced and spontaneous abortions, because complications of the two often are difficult to distinguish, and because restrictive abortion laws may deter accurate reporting. Thus, it was necessary to estimate and subtract the number of cases involving complications of spontaneous abortion. To do this, we applied an indirect method based on clinical studies that established the biological pattern of spontaneous abortion. Using this approach, we estimated that the number of miscarriages that occur at 13–22 weeks’ gestation (i.e., those likely to require facility-based care) was equal to 3.4% of the number of live births.6
For various reasons, including constraints on access to care, not all women who need care for late spontaneous abortions receive treatment at health facilities. We assumed that among Nigerian women who require such care, the proportion who receive care is the same as the proportion of women giving birth who receive antenatal care in a health facility—41% in the North West, 49% in the North East, 67% in the North Central, 91% in the South East, 73% in the South South, 90% in the South West and 61% nationally, according to the 2008 NDHS. Using these proxy proportions, we estimated that 142,430 women received care for spontaneous abortion in 2012, and subtracted this number from the total number of postabortion care patients to obtain an estimate of the number treated specifically for complications of induced abortion.
The next methodological step relied on responses of the knowledgeable health professionals. One of three outcomes is likely for women obtaining clandestine abortions: They may experience no health complications, or none serious enough to require care; they may experience complications, but not receive care; or they may have complications and obtain the care they need. Reasons for women’s not receiving care include stigma, cost, distance to a health facility and death before having a chance to receive care. Applying a number called a multiplier to the number of women treated for complications of induced abortion accounts for the women who do not need or receive treatment, and produces an estimate of the total number of abortions. For example, a multiplier of 4.0 means that one in four women who had an induced abortion received treatment for complications in a health facility. A small multiplier reflects either that abortion is generally unsafe or that access to medical care is high, whereas a large multiplier indicates that abortion is very safe or that many women do not have access to medical care. We calculated separate multipliers for each region (see Appendix for further details).
Because of the uncertainty inherent in our estimates, we calculated 95% confidence intervals around the total number of abortion complications (induced and spontaneous) treated in health facilities. We then applied the methodology described above to the low and high estimates of the number of treated complications to produce upper and lower estimates of abortion incidence (number and rate).
Treatment for Abortion-Related Complications
After adjustment of the original Health Facilities Survey data (see Appendix), we estimate that 354,400 women were treated for complications of spontaneous or induced abortion in Nigeria in 2012 (Table 2). Slightly more than half of these women (54%) were treated in public facilities (not shown); the proportion varied by region, ranging from 34% in the South South to 78% in the North East, likely reflecting differences in the availability and accessibility of private-sector facilities. Only in the South South and South East zones did public facilities treat fewer than half of patients who received postabortion care. Nationally, the majority of patients were treated at large hospitals, both in the public sector (59%) and private sector (56%). However, the situation varied among regions; for example, in the public sector, the proportion of women treated at hospitals ranged from 35% in the North Central region to 82% in the North West region.
After subtracting the number of women who had been treated for complications of late spontaneous abortions, we estimated that 212,000 women were treated for complications associated with induced abortion in Nigeria’s health facilities in 2012 (Table 3). These cases accounted for 60% of all women treated for any abortion-related complication in 2012 (not shown).
However, not every woman who has complications from unsafe abortion serious enough to require treatment in health facilities obtains the care she needs. According to estimates from the Health Professionals Survey, 40% of women who had an abortion in 2012 had complications warranting treatment in a facility. On the basis of this proportion, we estimate that an additional 285,000 women (or seven per 1,000 women aged 15–49) had abortion complications but did not receive care that year (not shown).
Number and Rates of Induced Abortion
The multipliers, which account not only for women who did not receive care for complications but also those who did not have complications, ranged from 3.9 in the South East to 8.4 in the North West (Table 3). Application of these multipliers yields an estimate that 1.25 million induced abortions occurred in Nigeria in 2012; our lower and upper estimates are 963,000 and 1.54 million. Overall, we estimate that the national induced abortion rate was 33 per 1,000 women aged 15–49 (confidence interval, 25–40 per 1,000), somewhat higher than the estimated rate of 25 per 1,000 women aged 15–44 (or 23 per 1,000 women aged 15–49) in 1996. Because of the large differences in the quality of reporting of clandestine abortion services, the two studies used different adaptations of the AICM, and deriving conclusions from a comparison of the data is difficult. However, the 1996 abortion rate of 23 per 1,000 women 15–49 falls just outside the confidence interval for the 2012 rate, suggesting that abortion incidence may have increased somewhat between 1996 and 2012.
Regional abortion rates varied widely. They were lowest in the North Central and South West zones (27 per 1,000 in each), slightly higher in the North West and South East zones (31 per 1,000 in each) and highest in the North East (41 per 1,000) and South South (44 per 1,000). To further put the number of induced abortions in context, the abortion ratio (number of abortions per 100 live births) was 19 per 100 nationally, and ranged from 14 per 100 in the South West to 25 per 100 in the South South.
Pregnancies and Their Outcomes
Obtaining a plausible estimate of the number of abortions allowed us to estimate the number of pregnancies that occurred in Nigeria in 2012. This number is the sum of the numbers of induced abortions, births and spontaneous abortions among women aged 15–49. To estimate the number of births, we applied age-specific fertility rates from the NDHS to the number of Nigerian women in five-year age-groups. Estimates of spontaneous abortion were calculated according to the formula (derived from clinical studies of pregnancy loss) that the number of spontaneous abortions occurring at five or more weeks’ gestation is approximately equal to 20% of the number of births plus 10% of the number of induced abortions.16,17
These calculations indicate that women aged 15–49 had about 9.22 million pregnancies in Nigeria in 2012 (Table 4). The overall pregnancy rate was 241 pregnancies per 1,000 women in this age-group. The rate was lowest in the South East (219) and highest in the South South (264). The national unintended pregnancy rate was 59 per 1,000 women aged 15–49; regionally, the rate ranged from 38 in the North West to 100 in the South South. Nationally, 24% of pregnancies in 2012 were unintended; the proportion was lowest in the North West (16%) and highest in the South South (38%).
The majority of Nigerian women’s pregnancies in 2012 ended in planned births. The proportion was 63% for the country as a whole, and ranged from 52% in the South South to 70% in the North West. About 14% of pregnancies ended in abortion; the proportion varied from 11% in the South West to 17% in the South South. At the national level, about 56% of unintended pregnancies ended in abortion (not shown); regionally, the proportion was lowest in the South West (43%) and highest in the North East (64%) and North West (81%). Fewer than half of unintended pregnancies in the three southern regions ended in abortion.
Mortality and Morbidity due to Unsafe Abortion
Nigeria has one of the highest maternal mortality ratios in the world.18 Although the government has acknowledged the problem and is committed to improving maternal health, evidence suggests that progress has been limited, and unsafe abortion remains a major contributor to maternal morbidity and mortality.
In a community-based survey conducted in 2002–2003, 25% of women who had had an induced abortion reported having had serious complications.19 Another study found that women who had been admitted to hospitals for complications of induced abortion had suffered a variety of complications, including retained products of conception (50%), bleeding (34%) and fever (34%).20 Two-thirds had had serious complications, such as sepsis, pelvic infections and injury from instruments, and some died.
A recent study recorded 137 maternal near-miss cases‡ in a six-month period at eight large hospitals across the country, and found that 13 (10%) were due to unsafe abortion.21 Another study estimated that in the late 1990s, about 3,000 women died annually from unsafe abortion in Nigeria.20 Because this estimate included only women who had died in health facilities, and not those who had died from unsafe abortion before reaching a facility, the actual number of deaths was likely higher.
We estimate that in 2012, about 212,000 women were treated in health facilities for complications of induced abortion, suggesting that unsafe abortion remains an important contributor to maternal morbidity and mortality in Nigeria. In addition, an estimated 285,000 women had complications serious enough to require treatment in health facilities, but did not obtain the care they needed. The impact of unsafe abortion extends beyond morbidity and mortality; there are also social costs to Nigerian women and their households, including the risks associated with breaking the country’s restrictive abortion law and the possibility of strong social sanctions.
Furthermore, unsafe abortion imposes a heavy financial burden on both women and Nigeria’s fragile health care system. For example, one study estimated that post-abortion care cost US$103 per patient in Nigeria in 2005, amounting to US$19 million; the average per-case cost for hospital care was US$132, of which 72% (US$95) was borne by women and their households.22
Unintended Pregnancy and Abortion
Findings from this study suggest that unintended pregnancy—the root cause of most abortions—is still occurring at moderately high levels in Nigeria. The high rates of unintended pregnancy and abortion are probably due largely to the combination of low prevalence of contraceptive use (especially use of modern methods) and the high proportion of women who need methods to avoid unwanted births or (particularly in the case of sexually active unmarried young women) to delay their first pregnancy. Women with the latter need are not an insignificant group: According to the 2013 NDHS, 40% of never-married women aged 15–19 had had sex, and about three-quarters of this group had done so within the past year.
Evidence from national surveys suggests that the number of abortions in Nigeria is likely to remain high in the absence of intervention. According to the 2013 NDHS, Nigerian women aged 15–49 had, on average, more children than they wanted (Table 5).10 Although the difference between total fertility and wanted fertility was not large, women in all six geopolitical zones had more children than they desired. The prevalence of contraceptive use remained at virtually the same low level as in the 2008 NDHS—only 16% of women of reproductive age were using a method, and only 11% were using a modern method, in 2013.10 In addition, 14% of women aged 15–49—and 22% of sexually active unmarried women in this age group (not shown)—had an unmet need for contraception, meaning that they did not want to have a child in the next two years or wanted no more children at all, but were not using any contraceptive method (Table 5). Women with unmet need commonly cite opposition to contraception (their own, their partner’s or that of another person, such as a family member) and fear of side effects as reasons for nonuse.24
The high rates of abortion in the North East and South South are likely related to factors that increase women’s need for abortion in these regions. The proportion of women in the North East who use contraceptives is the lowest in the country (3%), and the level of unmet need (16%) is higher than average. Although the social and demographic characteristics and contraceptive behavior of women in the North East are similar to those of their counterparts in the neighboring North West zone, the abortion rates differ greatly (41 vs. 31 per 1,000 women aged 15–19). This difference, together with the slightly higher rates of total fertility and wanted fertility in the North West compared with the North East, suggest that women in the former zone are more likely than those in the latter to carry their pregnancies to term.
Women in the three southern regions want smaller families (3.9–4.3 children) than do women in the northern regions (4.8–6.5), which may indicate that women in the southern regions have a relatively strong desire to limit their family size. Although the South South ranks second in the proportions of women using any contraceptive method (29%) and any modern method (18%), it also has the second highest level of unmet need (18%). This suggests that compared with women in other regions, those in the South South may be relying on abortion to a greater degree, and on contraception to a lesser degree, to achieve the smaller families they desire.
Like other indirect estimation techniques, the AICM has limitations. The data on the number of postabortion care cases treated in health facilities—a key input variable in our calculation of abortion incidence—are derived from respondents’ estimates. We must rely on these estimates because facilities’ official records are frequently inaccurate, grossly incomplete or nonexistent. We believe that a shift to social and religious conservatism has greatly affected the accuracy of facilities’ reporting of abortion provision in Nigeria; while respondents may be able to report reasonably accurate estimates of clandestine abortion services and of postabortion complication care, a comparison of estimates from this study with those from the previous one strongly suggests that many respondents grouped the two services together as postabortion complication cases in their reports, thus greatly reducing the reporting of abortions. Consequently, to calculate abortion estimates more realistically, we had to make several adjustments to ensure realistic abortion estimates. Moreover, to correct for noticeable underestimates and overestimates of postabortion care caseloads in some regions and facilities, we assumed that service provision in these regions and facilities was similar to that in some neighboring regions and facilities. These adjustments likely resulted in a conservative estimate of abortion incidence in Nigeria.
Lastly, lacking any direct information on this topic, we calculated the required multipliers using data on the perceptions of health professionals. While these respondents were carefully chosen and have extensive expertise on abortion-seeking behavior, the resulting multipliers are not exact measures; thus, we present confidence intervals around the estimates of abortion incidence.
Implications for Policies and Programs
Given the extent to which unsafe abortions are still occurring in Nigeria, there is strong need for the government and local and international stakeholders to make more concerted efforts to ensure that women do not continue to suffer or die needlessly from unsafe abortion. Since unintended pregnancy is the reason for most abortions, the most important—and least expensive—step is to promote access to contraceptive services to prevent such pregnancies. Programmatic efforts should strive to increase coverage, provide a wide range of contraceptive methods and improve the quality of care; women should have access to counseling and be able to switch methods easily when needed.
In 2012, at the Family Planning 2020 Summit in London, the Nigerian government made a commitment to increase the contraceptive prevalence rate to 36% by 2018 and to raise total spending on reproductive health commodities from US$12 million to US$45.4 million by 2016.25 While this step is laudable, achieving the goal of 36% will require not only that the government fulfill its financial commitment, but, equally importantly, that it be strategic in its choices of programs to pursue. The government of Ethiopia has shown, with its very successful Health Extension Program, that such a strategy is possible.26 The Nigerian government should carry out an assessment to identify the types of programs that will work best in the Nigerian context.
Because it typically takes time to see the effects on personal behavior of even the best policies and programs, and because contraceptive failures happen even among users of modern methods, some women will still seek unsafe abortions, at least in the short run. To help such women avoid long-term disability and even death, the government should continue to increase and improve access to appropriate, adequate and timely postabortion care services. Such efforts should focus on providing access to modern, appropriate and relatively noninvasive methods of postabortion care, such as manual vacuum aspiration and misoprostol; providing adequate training for relevant cadres of health providers; legally permitting and equipping midlevel health practitioners to provide postabortion care; and training providers to treat clients in a nonjudgmental manner. In addition, although only a small number of women may be eligible for legal abortion under the current law, which permits abortion only to save a woman’s life, an efficient process should be established to enable eligible women to have access to safe abortion services. To ensure that such abortions are performed safely, the government should promote training in the provision of safe abortion services at medical schools, during housemanship (postqualification training for young doctors, usually during their first two years) and during internships for medical students and personnel. Steps should also be taken to ensure that women seeking legal abortions have access to the procedure as early as possible, so that they can benefit from the use of modern, less invasive methods.
When women and couples begin to want smaller families—and continue to be motivated to space their births and avoid premarital childbearing—they will use a combination of means, such as modern or traditional contraceptive methods and abortion, to achieve their goals.27 Unless adequate measures are taken to prevent unwanted pregnancy and unsafe abortion, the health and well-being of women will continue to be at risk in Nigeria.
