Trends in and predictors of pregnancy termination among 15-24 year-old women in Nigeria: a multi-level analysis of demographic and health surveys 2003-2018

Factors influencing unintended pregnancy and abortion among unmarried young people in Nigeria: a scoping review

BACKGROUND

Unintended pregnancies and abortions among unmarried adolescents in Nigeria are outcomes of the interplay of multifaceted factors. Abortion, a global public health and social issue, impacts both developed and developing countries. This scoping review explored the literature and mapped the risk factors for unintended pregnancies and abortions among unmarried female adolescents in Nigeria.

METHODS

A scoping literature search was conducted across databases, including PubMed, Science Direct, Web of Science, EBSCOhost, JSTOR, African Index Medicus, and Scopus. Inclusion criteria encompassed peer-reviewed articles and reports in English, focusing on unmarried female adolescents. The range of interest included the past incidents of having sex, unintended pregnancies, contraceptive use, and abortions among this demographic. Studies categorized as grey literature were excluded to ensure the reliability and validity of the synthesized information.

RESULTS

A total of 560 articles, 553 identified through databases and 7 through hand search, were subjected to a comprehensive full-text review, resulting in the inclusion of 22 studies that met the criteria for the final review. The scoping review shed light on the past incidents of having sex, unintended pregnancies, contraceptive use, and abortions among unmarried adolescents in Nigeria. The range of incidence for having sex varied from 57.2% to 82.7%, with the prevalence of unintended pregnancies ranging from 23.4% to 92.7%. Contraceptive use was notably low, with 21.5% reporting low usage, contributing to the high incidence of abortions, ranging from 20.2% to 51.0%. Factors influencing unintended pregnancies included a lack of awareness of modern contraceptives and limited access to sexual and reproductive health information. For induced abortions, factors such as the impact on educational career, childbearing outside wedlock and fear of expulsion from school were identified.

CONCLUSION

This scoping review, through a systematic examination of existing literature, contributes to a more robust understanding of the factors influencing unintended pregnancies and abortions among unmarried adolescents in Nigeria. The findings inform future research directions and guide the development of targeted interventions to improve reproductive health outcomes for this vulnerable population.

Factors associated with pregnancy termination in six sub-Saharan African countries

Pregnancy termination continues to be a leading cause of maternal morbidity and mortality among young women in Africa. The sub-Saharan Africa region has the highest rate of abortion-related deaths in the world, at 185 maternal deaths per 100,000 abortions. The aim of this study is to investigate the factors associated with pregnancy termination among women aged 15 to 29 years in six sub-Saharan African countries. We used secondary data from the most recent Demographic and Health Survey of six sub-Saharan African countries: Kenya, Tanzania, Ethiopia, Burundi, Nigeria, and Rwanda. A total weighted sample of 74,652 women aged 15-29 were analyzed. A multivariable logistic regression model was used to identify the factors associated with pregnancy termination at a p-value < 0.05. Results were presented using adjusted odds ratios (AOR) with 95% confidence interval. The study showed that 6.3% of women aged 15-29 reported pregnancy termination with a higher prevalence rate in Tanzania (8.8%) and lowest in Ethiopia (4%). Highest odds of pregnancy termination occurred among women aged 20-24 as compared to women aged 15-19 in Rwanda (AOR: 4.04, 95%CI 2.05, 7.97) followed by Nigeria (AOR: 2.62, 95% CI 1.99, 3.43), Kenya (AOR: 2.33, 95%CI 1.48, 3.66), Burundi (AOR: 1.99 95%CI 1.48, 2.85), Tanzania (AOR: 1.71 95%CI 1.29, 2.27), and Ethiopia (AOR: 1.69, 95% CI 1.19, 2.42). Women with no education had 4 times higher odds of pregnancy termination compared to women with higher education in Tanzania (AOR: 4.03 95%CI 1.00, 16.13) while women with no education and primary level education were 1.58 times (AOR: 1.58 95% CI 1.17, 2.13) and 1.78 times (AOR: 1.78 95% CI 1.34, 2.37) as likely to terminate pregnancy in Ethiopia. In Tanzania, the likelihood of a pregnancy termination was associated with a relationship to the household head; head (AOR: 3.66, 95% CI (2.32, 5.78), wife (AOR: 3.68, 95% CI 2.60, 5.12), and in-law (AOR:2.62, 1.71, 4.03). This study revealed that a significant number of women had pregnancy termination. Being in the age group of 20-24 & 25-29, having a lower level of education, being a domestic employee and professional, being single/never-in-union, being in the poorest and richer wealth quantile category, and being head, wife, daughter, and in-law to the household head were the significantly associated with pregnancy termination. Taking these socio-economic factors into consideration by stakeholders and specific sexual education targeted to women aged 15 to 29 would help tackle the problem.

Prevalence and determinants of pregnancy termination in Ethiopia: a systematic review and meta-analysis

OBJECTIVE

This review aims to determine the prevalence of pregnancy termination and its determinant factors in Ethiopia.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Relevant articles were retrieved from databases such as PubMed, EMBASE, Medline and other search engines.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

The research design for this study had no restrictions, allowing for the inclusion of cross-sectional and case-control studies that examined the prevalence or determinants of pregnancy termination. However, case reports, case series, reviews, editorials and studies published as abstracts only were excluded from the analysis.

DATA EXTRACTION AND SYNTHESIS

The review was precisely in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria, and the quality of the review was assessed using the Joanna Briggs Institute critical appraisal checklist. Heterogeneity was indicated by the p value for I2 statistics less than 0.05. Data were entered into Microsoft Excel, and the analysis was conducted by using Stata V.16.

RESULTS

The pooled prevalence of pregnancy termination in Ethiopia was 21.52% (95% CI 15.01% to 28.03%). Women who had their first sexual initiation before the age of 18 (OR 1.78; 95% CI 1.13 to 2.82, p=0.14), had irregular menstrual bleeding (OR 1.86; 95% CI 1.25 to 2.77, p=0.76), being a student (OR 4.85; 95% CI 1.98 to 11.91, p=0.20) and had multiple sexual partners (OR 4.88; 95% CI 3.43 to 6.93, p=0.33) were significantly associated with pregnancy termination.

CONCLUSIONS

One in five women terminated their pregnancies, which is higher than in other sub-Saharan countries. Being a student, irregular menstrual bleeding, early initiation of sexual intercourse and multiple sexual partners were determinants of pregnancy termination. Special attention is needed in avoiding early sexual initiation and in reducing sexual risk behaviours.

A Longitudinal Multilevel Analysis of the Effects of Contraceptive Failures on Unintended Pregnancies among Women in Urban Nigeria

Unintended pregnancy is a global public health concern. However, the effect of contraceptive failure on unintended pregnancy remains unclear in Nigeria. We undertook a longitudinal analysis to examine the effect of contraceptive failure on unintended pregnancy among urban women in Nigeria. We used panel data from the Nigerian Urban Reproductive Health Initiative. The Measurement, Learning and Evaluation program conducted the surveys among a cohort of women aged 15-49 who were first interviewed at baseline in 2010/2011 and followed up at endline in 2014/2015. Analytic sample was 4140 women aged 15-49 who ever used contraceptives. We fitted three-level multilevel binary logistic regression models estimated with GLLAMM. The study established evidence that there is a significant effect of contraceptive failure on unintended pregnancy among urban women in Nigeria. The positive effect of between-person contraceptive failure indicates that respondents who experienced more contraceptive failure than the average in the sample had 5.26 times higher odds of unintended pregnancy (OR = 5.26; p-value < 0.001). Results also established a significant effect of within-person contraceptive failures among the respondents. Findings suggest there is evidence of a significant longitudinal effect of contraceptive failure on unintended pregnancy in urban Nigeria. Efforts to reduce unintended pregnancy must include interventions to address the problem of contraceptive failure among urban women in Nigeria.

Intimate partner violence as a determinant of pregnancy termination among women in unions: evidence from the 2016-2018 Papua New Guinea Demographic and Health Survey

There is a demonstrated link between intimate partner violence (IPV) and pregnancy termination, and this association has received much attention in developed settings. Despite the high prevalence of IPV in Papua New Guinea (PNG), little is known about the association between these experiences and pregnancy termination. This study examined the association between IPV and pregnancy termination in PNG. The present study used population-based data from the PNG's first Demographic and Health Survey (DHS) conducted in 2016-2018. The analysis involved women aged 15-49 years who were in intimate unions (married or co-habiting). We used binary logistic regression modelling to analyse the association between IPV and pregnancy termination. Results were reported as crude odds ratios (cOR) and adjusted odds ratios (aOR) with 95% confidence intervals (CIs). Overall, 6.3% of women involved in this study had ever terminated a pregnancy, and 6 in 10 women (61.5%) reported having experienced IPV in the last 12 months preceding the survey. Of those women who experienced IPV, 7.4% had ever terminated a pregnancy. Women who had experienced IPV had a 1.75 higher odds of reporting pregnancy termination (cOR: 1.75; 95% CI: 1.29-2.37) than women who did not experience IPV. After controlling for theoretically and empirically relevant socio-demographic and economic factors, IPV remained a strong and significant determinant of pregnancy termination (aOR: 1.67, 95% CI: 1.22-2.30). The strong association between IPV and pregnancy termination among women in intimate unions in PNG calls for targeted policies and interventions that address the high prevalence of IPV. The provision of comprehensive sexual reproductive health, public education, and awareness creation on the consequences of IPV, regular assessment, and referral to appropriate services for IPV may reduce the incidence of pregnancy termination in PNG.

Patterns and Predictors of Abortion Care-Seeking Practices in India: Evidence From a Nationally Representative Cross-Sectional Survey (2019-2021)

Background India continues to have unsafe abortions despite progressive legislation since the past five decades facilitating ease of access to abortion services. This study describes abortion care-seeking patterns (social/therapeutic/humanitarian/sex-selective/safe/unsafe), preferences (public/private/at home), and their determinants among Indian women. Methods Data were taken from the Indian National Family and Health Survey (NFHS-5) (2019-2021) including women aged 15-49 years, who had terminated their last pregnancy by induced abortion within five years prior to the survey (N = 5,856). A bivariate analysis, followed by a multinomial logistic regression model, was performed to assess the predictors affecting the choice of healthcare facility type for an abortion. Predictors of unsafe and self-managed abortions were examined using binary logistic regression. Results About 665,671 women in the reproductive age group responded to the survey, of which 3.42% (n=22,767) reported their most recent pregnancy within the last five years terminated in either a miscarriage, stillbirth or abortion, of which 5,856 (25.72%) underwent an induced abortion. Women undergoing surgical abortion were more likely to avail of either a public (adjusted relative risk ratio (aRRR)=38.06 (23.62, 61.35)) or a private facility (aRRR=44.53 (28.11,70.53)) compared to at-home abortions. Women reporting a social and humanitarian reason for abortion were less likely to undergo an abortion at a public (aRRR=0.25 (0.17,0.35)) or private facility (aRRR=0.32 (0.23,0.44)) than at home. Furthermore, a total of 147 (2.43%) abortions were classified as unsafe. Women reporting sex-selective reasons for abortion were observed to have a higher likelihood of engaging in an unsafe abortion (adjusted odds ratio (aOR)= 1.61 (0.70, 3.70)) compared to those citing a therapeutic reason. Conclusions Self-managed abortions at home were more prevalent in women of lower socioeconomic status, adolescent girls, and those reporting sex-selective reasons for abortion. Furthermore, the reproductive-health program in India should enhance capacity-building initiatives for primary-care healthcare providers, including doctors, nurses, and pharmacists, to effectively prescribe and supervise abortion through medication methods.

Factors associated with adolescent pregnancy and public health interventions to address in Nigeria: a scoping review

BACKGROUND

Adolescent pregnancy is a global public health and social problem that affects both developed and developing countries. Reducing adolescent pregnancy is central to achieving sustainable development goals. In 2021 Nigeria's Adolescent pregnancy was 106 per 1000 and showed an increasing rate. This study, therefore, aims to explore the literature to map the risk factors and interventions against adolescent pregnancy in Nigeria.

METHOD

A scoping review of studies published between January 2007 and December 2022 using PubMed, Web of Science and Africa Journals Online were searched using the keywords' adolescent pregnancy' AND 'Nigeria'. Studies were screened using the eligibility criteria.

RESULTS

A total of 241 articles, of which 229 were identified through the databases and 12 were identified through hand search. After the full-text review, 28 studies met the inclusion criteria and were included in the final review. In Nigeria, the prevalence of adolescent pregnancy is between 7.5 and 49.5%. Associated factors for adolescent pregnancy in Nigeria are multifactorial, including individual, community, societal, school, family, and peer factors. Policies on adolescent sexual and reproductive health exist in Nigeria. Still, the policies need more sponsorship, implementation, and monitoring, while only some interventions on adolescent pregnancy majorly based on contraceptives and education of health providers are available in Nigeria.

CONCLUSION

Associated factors for adolescent Pregnancy in Nigeria are multidimensional, with educational attainment and wealth index being the highest associated factor. Intervention strategies aimed at the educational level have been identified as a critical factor in curbing adolescent pregnancy. Thus, policies on sexual, reproductive, and mental health development specifically targeting adolescents to reduce the cycle of societal dependence by empowering this group economically and educationally are justifiably warranted.

Pooled prevalence and associated factors of pregnancy termination among youth aged 15-24 year women in East Africa: Multilevel level analysis

BACKGROUND

Most of unwanted pregnancies among adolescent girls and young women (AGYW) in Africa result in pregnancy termination. Despite attempts to enhance maternal health care service utilization, unsafe abortion remains the leading cause of maternal death in Sub-Saharan Africa (SSA), there is still a study gap, notably in East Africa, where community-level issues are not studied. Therefore, this study aimed to assess pooled prevalence pregnancy termination and associated factors among youth (15-24 year-old) women in the East Africa.

METHODS

The study was conducted based on the most recent Demographic and Health Surveys (DHS) in the 12 East African countries. A total weighted sample of 44,846 youth (15-24) age group women was included in this study. To detect the existence of a substantial clustering effect, the Intra-class Correlation Coefficient (ICC), Median Odds Ratio (MOR), and Likelihood Ratio (LR)-test were used. Furthermore, because the models were nested, deviance (-2LLR) was used for model comparison. In the multilevel logistic model, significant factors related to pregnancy termination were declared using Adjusted Odds Ratios (AOR) with a 95%Confidence Interval (CI) and p-value of 0.05.

RESULT

The pooled prevalence of pregnancy termination in East African countries was 7.79% (95% CI: 7.54, 8.04) with the highest prevalence in Uganda 12.51% (95% CI: 11.56, 13.41) and lowest was observed in Zambia 5.64% ((95% CI: 4.86, 6.41). In multilevel multivariable logistic regression result, age 20-24 [AOR = 1.93; 95% CI: 1.71, 2.16], media exposure [AOR = 1.22; 95% CI: 1.12, 1.34], married [AOR = 1.32, 95% CI: 1.21, 1.43], had working [AOR = 1.13; 95% CI: 1.04, 1.23],no education[AOR = 3.98, 95% CI: 2.32, 6.81], primary education [AOR = 4.05, 95% CI: 2.38, 6.88], secondary education [AOR = 2.96, 95% CI: 1.74, 5.03], multiparous [AOR = 0.85; 95%CI: 0.79, 0.93], sexual initiation greater or equal to 15 [AOR = 0.82; 95%CI: 0.74, 0.99] were significantly associated with pregnancy termination.

CONCLUSION

The pooled prevalence of pregnancy termination in East Africa was high in this study. Maternal age, marital status, education status, parity, age at first sex, media exposure, working status and living countries were significantly associated with pregnancy termination. The finding provides critical information for developing health interventions to decrease unplanned pregnancies and illegal pregnancy termination.

Association of alcohol consumption with abortion among ever-married reproductive age women in Ethiopia: A multilevel analysis

Background

A miscarriage or a spontaneous loss of a pregnancy that occurs before the 20th week is an abortion. Even though numerous recommendations state that pregnant women should abstain from alcohol at all stages of pregnancy, alcohol intake among pregnant women is common. However, there are few papers addressing the effect of alcohol use on miscarriage using nationally representative data. Moreover, the association of alcohol use with abortion and its mechanisms is not well studied in the Ethiopian region. Therefore, the objective of the current study was to estimate the association of alcohol use with abortion rates among reproductive age (15-49) women in Ethiopia.

Methods

Using the most recent findings of the Ethiopian Demographic and Health Survey (EDHS), secondary data analysis was performed among pregnant women in Ethiopia. A total of 11,396 women between the ages of 15 and 49 years who were of reproductive age were included in the research. To characterize the study population, descriptive statistics were used. The variability was considered using the multilevel binary logistic regression model. A multilevel binary logistic model was used to determine the effect of alcohol intake on abortion while controlling for potential confounders. In the multivariable analysis, variables with a P-value of less than 0.05 were considered statistically significant for the response variable.

Results

The proportion of women who had an abortion was 10.46% with a 95% CI of 9.92-11.03. In the final model of the multilevel analysis, age group [adjusted odds ratio (AOR) = 6.13; 95% CI: 3.86-9.73], education level (AOR = 1.29; 95 and CI: 1.10-1.51), alcohol consumption (AOR = 1.38; 95% CI: 1.18-1.61), age at first sex (AOR = 1.20; 95% CI: 1.03-1.39), media exposure (AOR = 1.28, CI: 1.10-1.48), contraceptive use (AOR = 1.34, CI: 1.16-1.56), and occupation of respondent (AOR = 1.21, CI: 1.06-1.38) were identified to be significant determinants of abortion in Ethiopia.

Conclusion

Sexual and reproductive health education and family planning programs should target older women in the reproductive age group, women with primary educational status, working women, and those who initiated sexual intercourse at a younger age considering it could reduce abortion and unintended pregnancy. Furthermore, as part of sexual and reproductive health education, the adverse effect of alcohol consumption on abortion should be emphasized.

Intimate Partner Violence and Pregnancy Termination in Armenia: Evidence from Nationally-Representative Survey Data

Intimate partner violence has been associated with numerous consequences for women, including pregnancy termination. This study examined the association between predictive capacity of intimate partner violence and pregnancy termination among women in Armenia. The study analyzed the 2015-16 Armenia Demographic and Health Survey (ADHS) data on women aged 15-49 (Mean: 31.49; Standard Deviation, SD: 9.51). Marital control exercised by husbands, ever experienced physical violence, sexual violence, and emotional violence by husbands were the four indicators of intimate partner violence used in this study. To assess the association between intimate partner violence and pregnancy termination, a binary logistic regression model was fitted. After controlling for confounders, we found that women whose husbands exercised marital control were 26% more likely to experience pregnancy termination, compared to women whose husbands did not exercise marital control (adjusted odds ratio (aOR): 1.26, 95% Confidence interval (CI): 1.03-1.53). Women who ever experienced sexual violence were about 10 times likely to experience pregnancy termination than women who did not experience sexual violence (aOR: 9.76, 95% CI: 1.91-49.96). Both ever experienced physical violence and emotional violence did not have any significant associations with pregnancy termination. Forms of intimate partner violence are associated with pregnancy termination. The findings of this study provide evidence for government and policymakers to formulate, modify, and implement policies and program that target both men and women regarding the prevailing intimate partner violence and its consequences. Strengthening the policy implementation will ensure that women are empowered to make decisions about their reproductive health. Making husbands and their family members aware of the basics and consequences of intimate partner violence and focusing on child cognitive development which can be hampered due to the prevalence violence in families are recommended.

Determinants of abortion among youth 15-24 in Ethiopia: A multilevel analysis based on EDHS 2016

INTRODUCTION

Determinants of the magnitude of abortion among women of diverse social and economic status, particularly in Africa poorly understood because of the missing information in most countries. In this study, we addressed abortion and its determinants among youth women of 15-24 ages to provide clear direction for policymaking in Ethiopia.

METHODS

We examined the 2016 Ethiopian demographic health survey data downloaded from the EDHS website after obtaining permission on abortion among 15-24 age women. We applied bivariate and multilevel binary logistic regression. Community and Individual level abortion predictors passed through a three-level binary logistic regression analysis where we used p-value <0.05 and adjusted odds ratios (AOR) with 95% confidence intervals (CI).

RESULT

The abortion among the youth population in this study was 2.5%. Factors associated with pregnancy were age group 20-24 2.5(1.6-3.8), youth with one birth 0.65(0.44-0.96), youth with 2-5 births 0.31(0.18-0.55), age ≥18 0.50(0.33-0.76), married 38(17-84), divorced 20(7-55), birth in the last five years 0.65(0.44-0.96), middle wealth youth 1.7(1.0.4-2.8), being in Amhara0.31(0.11-0.85), and 0.30(0.12-0.77).

CONCLUSION

Less abortion occurred in economically poor youths. It is a noble finding; however, the access problem might lead to the result. We observed more abortions in age <18years; those have not given birth until the data collection date. It portrays forth clear policy direction for politicians and all other stakeholders to intervene in the problem. The analysis also showed abortion increased with age. It shows that as age increased, youths disclose abortion which is rare at an early age, and again given an essential clue for the next interventions. The fact in this study is both age and marriage affected abortion similarly. It might be because of various culture-related perceptions where it is not appropriate for an unmarried woman to appear with any pregnancy outcome as the reason behind the decreased number of abortions at a younger age. Thus, more attention is required during implementation for unmarried and lower age youth regardless of the magnitude of the abortion.

Intimate partner violence against adolescent girls and young women and its association with miscarriages, stillbirths and induced abortions in sub-Saharan Africa: Evidence from demographic and health surveys

Intimate partner violence has been associated with numerous consequences for women, including pregnancy termination. This study aimed to examine the association between intimate partner violence and pregnancy termination among adolescent girls and young women in 25 sub-Saharan African countries. Data for this study was obtained from the demographic and health surveys of 25 countries in sub-Saharan Africa, published between 2010 and 2019. A total of 60,563 adolescent girls and young women were included in this study. Binary logistic regression models were used in analyzing the data and the results were presented as crude odds ratios (CORs) and adjusted odds ratios (AORs) at 95% confidence interval (CI). The prevalence of intimate partner violence and pregnancy termination among adolescent girls and young women in the 25 countries in sub-Saharan Africa were 19% and 10.1% respectively. In all these countries, the odds of pregnancy termination was higher among adolescent girls and young women who had ever experienced intimate partner violence, compared to those who had never experienced intimate partner violence [COR = 1.60, 95% CI = 1.51-1.71], and this persisted after controlling for confounders [AOR = 1.58, 95% CI = 1.48-1.68]. However, across countries, intimate partner violence had significant association with pregnancy termination among adolescent girls and young women in Angola, Chad, Congo DR and Gabon (Central Africa); Benin, Burkina Faso, Cote D'lvoire, Gambia and Mali (West Africa); Comoros, Rwanda and Uganda (East Africa); and Malawi and Zambia (Southern Africa). The findings imply that reducing pregnancy termination among adolescent girls and young women in sub-Saharan Africa depends on the elimination of intimate partner violence. Thus, policies and programmes aimed at reducing pregnancy termination among adolescent girls and young women in sub-Saharan Africa, should pay particular attention to those who have history of intimate partner violence.
