Association between Intimate Partner Violence and Abortion in Nepal: A Pooled Analysis of Nepal Demographic and Health Surveys (2011 and 2016)
Background. Intimate partner violence (IPV) adversely affects female reproductive health in different ways. However, the relationship between IPV and abortion has not been adequately examined in Nepal. This study is aimed at examining the association between IPV and abortion in Nepal. Methods. Data for this study was derived from the Nepal Demographic Health Surveys (NDHS) of 2011 and 2016. A total of 8641 women aged 15-49 years were selected for the violence module in NDHS 2011 and 2016. The analysis was restricted to 2978 women who reported at least one pregnancy five years preceding each survey. Among them, 839 women who experienced different forms of violence were included in the analysis. Various forms of IPV were taken as exposure variables while abortion as an outcome of interest. The study employed logistic regression analysis to examine the association between IPV and abortion. Results. Nearly one in three (28.2%) women experienced any forms of IPV. A total of 22.2% women experienced physical violence. Almost one in five (19.5%) women were slapped. More than half (52.8%) of the women with no education experienced IPV. The logistic regression analyses showed a significant association between IPV and abortion. Women with severe physical violence had nearly two-fold higher odds (adjusted Odds Ratio ; 95% CI: 1.06, 2.64) of having abortion. Similarly, women who reported physical violence were more likely to have abortion (; 95% CI: 1.09, 2.19) compared to those who did not experience such violence. Conclusion. Intimate partner violence is associated with abortion in Nepal. It is imperative that effective implementation of IPV-preventive measures through the promotion of appropriate social and policy actions can help reduce abortion in Nepal.
Intimate partner violence (IPV) is defined as any behaviour within an intimate relationship that causes physical, sexual, and psychological harm . These behaviours include but not limited to the act of physical aggression, sexual coercion, and psychological abuse . Violence against women is a serious public health problem [2–5]; it is considered as a violation of human rights [6, 7]. It is evident that IPV during pregnancy places women in a greater vulnerable situation and has been documented as an important contributor to adverse maternal and fetal health outcomes . Adverse maternal health outcomes include unintended pregnancy, induced abortion, miscarriage, pregnancy complications, hypertension, delivering low birth weight, physical injuries, stress, and lack of fertility control and personal autonomy [4, 6, 7, 9–11]. Studies conducted in Bangladesh found that women in violent relationships are more likely to report miscarriage and stillbirth [7, 12]. A multicountry review study found that 30% of the partnered woman (aged 15–69 years) experienced physical or sexual violence in their lifetime .
In Nepal, violence against women is common that 51.9% of young women experience physical and sexual violence in their lifetime . Nepal is a patriarchal society, and gender-based discrimination is highly prevalent [15–17]. In a patriarchal culture, men tend to have higher control over women decision making and health seeking practices and women lack control of resources. More than two-fifth (44%) of men agreed that women deserve to be beaten while 21% of men and 23% of women believed that husband beating spouses is justified if wives refuse to have sex on demands [2, 18]. A global multicountry review study has reported that almost half of the women globally suffer physical abuse from their partner . Past evidence from Nepal showed a higher proportion of physical violence during reproductive age . A study conducted in four districts of Nepal showed that nearly three in five women (59.2%) ever experienced some forms of violence from their partner . A hospital-based study conducted among 950 urban pregnant women in the capital city of Nepal revealed that 33% of women experienced psychological and physical violence and sexual abuse during pregnancy .
Literature suggests that women in a violent relationship may have limited or no control over mutual sexual intercourse [12, 21]. It is urged that controlling behaviour of partner can restrict women from accessing the family planning methods [21, 22], which may lead to unwanted pregnancies and abortion . Evidence also suggested that abortion was associated with the experience of IPV among women [12, 24], so as the higher rate of unintended pregnancy . A study in Bangladesh revealed higher rates of unintended pregnancy among women who experienced severe forms of physical violence . Studies conducted in China and the USA reported that most abortions end with unintended pregnancies, which mainly result from ineffective use and/or nonuse of contraceptives [27–30] and rape being the leading cause of pregnancy termination .
In Nepal, abortion is considered to be the third leading cause of maternal death . Nepal legalised abortion in 2002, and both the public and the private sectors started providing abortion services across the country since 2004 . The common reasons for abortion as reported in Nepalese literature are women’s knowledge of abortion legality, maternal and fetal health risk, lack of desire for children, child spacing, child sex, and low income [29, 31–33]. Studies from countries in South Asia, primarily in Bangladesh , India , and Pakistan  have established an association between IPV and unwanted pregnancies. However, there is a lack of clarification on the impact of IPV with abortion [34, 37].
A large body of literature has examined and established the relationship between IPV and abortion, especially in low- and middle-income countries (LMICs). Despite the availability of nationally representative data from the NDHS, there have been limited studies conducted to examine the association between IPV and abortion in Nepal. This study is aimed at estimating the prevalence of intimate partner violence and examining the association between IPV and abortion. Findings from this study are expected to inform policymakers, program managers, and public health professionals to design policies and programmatic strategies on abortion services in Nepal.
2.1. Study Design and Sampling
The present study used nationally representative survey data from the Nepal Demographic and Health Survey (NDHS) 2011 and 2016 (available from https://dhsprogram.com/data/available-datasets.cfm). Detailed sampling methodology is provided in reports of NDHS 2011  and 2016 . In brief, NDHS used multistage cluster sampling design and collected data on several sociodemographic and health indicators, including IPV, and abortion. The average response rate of NDHS 2011 and 2016 was 98%. From NDHS 2011() and 2016 () data, a total of 8641 women aged 15–49 years who were selected to participate in the violence module survey were merged for this study. The violence module of the survey consists of questions on domestic violence that was administered in the subsample of households. Only one eligible woman per household was randomly selected for the module. Special sampling weights were used to adjust for the selection of only one woman per household and to ensure that the violence subsample was nationally representative [17, 19].
Figure 1 shows the participants included for this study. A total of 8641 women were selected from the NDHS 2011 and 2016. About 78% of the total selected women participated and responded to the violence module, which included 3225 women in 2011 and 3562 in 2016. Furthermore, excluding unmarried and divorced, 6531 married women aged 15-49 years responded to the violence module in both surveys. Moreover, one-third of the total selected women (2978) were currently married and living with a husband and had at least one pregnancy during the study period (Figure 1).
2.2. Outcome Variable
In NDHS 2011 and 2016, women were asked to report all pregnancy outcomes (live birth, stillbirth, miscarriage, and abortion) five years prior to each survey. To capture pregnancy that resulted in abortion, women were further asked if something was done to terminate the pregnancy [17, 19]. The outcome variable of this study was abortion coded as “1” (if something was done to end the pregnancy) and “0” (otherwise) [17, 19].
2.3. Exposure Variables
The exposure variables were women exposed to any form of physical, sexual, and emotional violence by their partner. In NDHS, different types of violence were measured by asking a series of questions. If women were hit, slapped, kicked, or done something else to hurt by husband/partner were considered as physical violence. If women were forced by threats or in any other way to have sexual intercourse or to perform any other sexual acts or they did not want to do so were considered as sexual violence. Similarly, if the respondents had ever been humiliated, threatened with harm and insulted, or made to feel bad by husband/intimate partner were categorised as emotional violence. Specifically, any physical violence included any of the following behaviours from a husband/partner: (i) pushing, shaking, or throwing something at her; (ii) slapping her; (iii) twisting an arm or pulling her hair; (vii) punching with partner’s fist or with something that could hurt her; (v) kicking her, dragging her, or beating her up; (vi) choking or burning; and (vii) threatening or attacking with a knife or other weapon. The physical violence in original data files of NDHS 2011 (NPIR60FL) and 2016 (NPIR7HFL) has been categorized as less severe and severe. Any less severe physical violence included (i) pushing, shaking, and throwing something at female partner; (ii) slapping; (iii) twisting arm or pulling hair; or (iv) punching with partner’s fist or with something that could hurt her; any severe physical violence included (i) kicking, dragging, or beating up; (ii) choking or burning; or (ii) threatening or attacking her a knife or other weapon.
Covariates were selected based on previous studies [31, 38, 39] and the available information in the NDHS 2011  and 2016 , including wealth status, ethnicity, age of respondents, level of education, women’s empowerment in decision making, and intimate partner’s addiction of alcohol consumption. Variables such as ethnicity, age and education status were further categorised for this study. The Government of Nepal has categorised ethnicity into six groups Dalit (Hill and Terai), Janajati (Indigenous Hill and Terai caste group), Madhesi (non-Dalit Terai caste groups), religious minorities (Muslims), upper-caste groups (Brahman/Chhetri), and Others (Thakuri and Sanayshi). However, socioeconomic and geographical similarities [38, 40] in ethnicity was categorised into four groups: Brahman/Chhetri, Janajati, Dalit, and Others, including Muslims and Madhesi. Respondent’s age was categorised into three groups: 15-24 years, 25-34 years, and 35-49 years. The education level for respondents and their husbands/partners were categorised into four groups: none (no education), primary (1-5 grades), secondary (9-10 grades), and higher (year 11 or above). The number of living children as reported by women was categorised into four groups: none, 1 child, 2 children, and three or more children. The ecological region was categorised as (1) Mountain, (2) Hill, and (3) Terai. The NDHS applied an asset-based approach to estimate household wealth quintile, and household wealth status was categorized as poorest, poorer, middle, richer, and richest . In regard to women’s decision making power on their own health care (whether women participated in at least one of the decisions regarding their own health care, major household purchases or visits to their family or relatives) , it was categorised into three groups: involvement of husband and other members, involvement of husband and women, and involvement of respondent alone. Husband/partner’s alcohol drinking habit was categorised as yes or no.
2.5. Conceptual Framework
Figure 2 illustrates the relationship between violence and abortion. For this study, we adopted and revised the conceptual framework developed by Azevedo and colleagues (2013) (Figure 2). The framework comprises of sociodemographic characteristics of women, characteristics of partner, and other risk factors. The framework guides this study to conceptualize the relationship between IPV and abortion (Figure 2).
2.6. Statistical Analysis
Data were analysed using STATA (version 14.1) (Stata Crop, Texas, USA). In the descriptive analyses, the characteristics of the study participants were presented in the form of frequency number and the proportion (%) with 95% confidence intervals (CI). Logistic regression models were used to examine the association between each exposure variable (different forms of IPV) and abortion. Survey function “svy” in STATA was applied to adjust for sampling weight and clustering effect, and value < 0.05 was considered a significant level.
2.7. Research Ethics
This study used publicly available secondary data derived from the NDHS 2011 and 2016. These surveys were approved by an ethical review board of ICF Marco International, Maryland, USA, as well as from the Nepal Health Research Council. The first author got permission from DHS program (USA) to use those datasets for this study. The DHS data are publicly available and accessible at https://dhsprogram.com/data/available-datasets.cfm on online request.
Table 1 shows the different forms of IPV. A total of 28.2% of women experienced any forms of IPV. More than one in five (22.2%) women experienced physical violence. Nearly one-fifth of women (19.5%) were slapped, and 13.6% were pushed and shook by their partner. Over one in ten (11.2%) women experienced sexual violence. Additionally, one in five (21.8%) women experienced less severe physical violence followed by emotional violence (14.0%). Almost one in 10 (9.4%) women experienced any severe physical violence (Table 1).
Table 2 presents the prevalence of different forms of IPV and abortion five years preceding the survey. Over a quarter (28.2%) of women reported having ever experienced any form of IPV. One in ten (10.2%) women reported abortion (Table 2).
Table 3 shows the sociodemographic characteristics of the participants () included in this study. Women experiencing IPV varied from 2.6% (women having no living children) to 59.3% (women who live in Terai region). Over a quarter (28.2%) of women experienced any forms of IPV. Of 839 women who experienced violence, more than half (52.8%) of the women with no education experienced IPV in their pregnancy. More than two in five women (44.6%) with IPV were from women whose husband educated secondary or higher-level, and 48.5% of women were aged 25-34 years. A quarter of women from the middle-wealth quintile and 3 in 10 Janajati (indigenous groups) women experienced IPV. Nearly half (46.6%) with a husband with a history of alcohol use and just over six in 10 women having husband and other members involved in decision making for her own health experienced IPV (Table 3).
Table 4 shows abortion among women with and without IPV. Overall, almost 1 in 10 (9.8%) women had abortion. Just over one-tenth (10.2%) women who experienced IPV had abortion. Nearly two in five (39.3%) of the women with two living children experienced violence and had abortions. Furthermore, more than half (56.0%) of the women with secondary or higher education who experienced IPV had abortions. Less than half (44.7%) of the women involved in decision making of her own health with her husband experienced violence and had abortion. Over 6 in 10 (62.3%) of women with a history of husband's alcohol use who experienced IPV had abortions (Table 4).

Table 5 shows the association between various forms of intimate partner violence and the likelihood of abortion. In multivariate logistic regression analysis, a significant association was found in IPV and the risk of abortion. Women ever experiencing any severe violence had the strongest association (; 95% CI: 1.06, 2.64) with abortion. Women who experienced physical violence were also more likely to have abortion (; 95% CI: 1.09, 2.19) compared to those who did not experience violence. The lower odds value was observed for women ever experiencing emotional violence (; 95% CI: 0.79, 1.74). Women ever experiencing any kinds of IPV was significantly associated with abortion (; 95% CI: 1.01, 1.90) than those who have not experienced violence (Table 5).
value obtained from the chi-squared test. Each type of violence was comprised of an independent regression model. †Significant at . #Adjusted for the following covariates: survey year, ecological region, household wealth, woman’s education, husband’s education, ethnicity, age, and number of living children, women’s decision making on own health care, and husband’s alcohol drinking habit.
Our study also found that women whose husband had a history of alcohol use were more likely to have abortion (; 95% CI:1.09, 1.93) compared to those without the history of alcohol use (Supplementary Table 1).
Despite numerous reproductive health care policies and programs in place, the prevalence of women who experience IPV in Nepal is high. This study found that women who experienced IPV are more likely to have abortion compared to those who did not experience violence.
The finding of higher abortion among women who experienced partner violence in our study is in agreement with previous research conducted in Nepal [8, 14, 41] India , Bangladesh [10, 34], and Pakistan . The relationship between unwanted pregnancy and abortion has been well documented [34–36, 41]. A possible reason of higher abortion among women who experience IPV in this study may be that women in abusive relationships have low autonomy over their sexual lives; and therefore, can lead to unwanted pregnancy  and abortion .
Consistent with our finding, women with physical violence reported higher abortion rates in a number of studies conducted in India, [24, 44] Bangladesh [10, 34], and other African countries [45, 46]. In a violent spousal relationship, abortion can occur through various pathways. Firstly, women who experience partner violence may face pregnancy coercion which is often linked with lower contraception use and higher unintended pregnancy . The association between unintended pregnancy and higher abortion has been previously established [24, 47]. Secondly, women in abusive relationships are more vulnerable to experience termination of pregnancy as they feel less prepared emotionally, socially, and financially to take care of a child into a violent setting which may influence women’s decision for abortion . Thirdly, poor uptake of health services, especially delayed in seeking antenatal care and injuries during pregnancy, may result in abortion [48, 49]. Previous studies have shown that higher IPV and lower women’s autonomy in decision making led to unintended pregnancies due to lack of access to emergency family planning services [24, 34, 50]. We found that women whose husband has a history of alcohol use were more likely to experience abortion than those with no alcohol use. A possible explanation could be that the husband’s alcohol consumption may also lead to forced sex and lack of contraception use, resulting in unwanted pregnancies and abortion .
Despite the positive association, the relationship between sexual violence and abortion in this study was not statistically significant. Consistent with the findings of this study, the previous study from Bangladesh reported no association between sexual violence and abortion , and a similar study conducted in the USA revealed lower rates of abortion among women who experienced sexual violence . A possible reason could be a high stigma associated with talking about sex in Nepalese society as women might feel embarrassed to reveal their experience of sexual violence . Generally, there is a perceived notion that forceful sexual acts by intimate partner do not constitute violence in Nepal , and stigma may have led such incident . A multicountry study conducted by the WHO reported the higher acceptance of sexual violence compared to physical violence [1, 21]; and studies conducted in Nepal [54, 55] stated the lower rate of sexual violence due to underreporting. Unlike our study, the positive association between sexual violence and abortion has been reported in India and Bangladesh [10, 22]. A study from Nepal reported an association with sexual violence and unintended pregnancy , which may have occurred due to male dominance in a sexual decision, limited women’s control over fertility, and limited access and use of contraceptives .
The emotional violence in the present study was not significantly associated with abortion. The findings are similar to those from studies conducted in Bangladesh  and Cameroon . The possible explanation could be due to a lack of awareness about emotional violence and poor reporting . Contrary to this study, a study conducted in Pakistan  and Kenya  reported a stronger association between emotional violence and abortion. The possible reason for higher abortion among women who reported emotional violence in Pakistani and Kenyan studies could be due to poor partner communication regarding reproductive health issues and reproductive inequality in violent relationships which may undermine the use of contraceptives [12, 57].
The current findings underline the importance to adopt effective strategies for married women and their partner in Nepal to reduce IPV and abortion. The Government of Nepal has focused on reducing abortion associated with maternal deaths through improving access to family planning methods. However, the use of such methods may be complex for women in a violent relationship. So, the appropriate measures through existing family planning program may be beneficial [7, 58–60]. Long-acting reversible contraceptive (LARCs) methods can reduce the risk of unintended pregnancy. Moreover, it should be assured that contraception should be easily accessible and widely available through government health facilities that will encourage women to use, even when they have lower autonomy by partner violence [7, 41].
The strengths of the present study include firstly, the analysis was based on pooled data of two consecutive nationally representative surveys conducted in 2011 and 2016 in Nepal, which maximised the sample size and improved the generalizability of the results to the wider population. Secondly, the NDHS used a pretested and well-designed questionnaire along with trained interviewers for data collection with good reliability. Thirdly, to our knowledge, this is the first national-level study to examine the association between IPV and abortion in Nepal, and the findings of this study may have some implications for countries of similar culture within South Asia. However, this study is limited by a number of reasons. First, it was a survey design which does not provide us with inferences regarding causality. Second, the underreporting of sexual violence due to more sensitive topic may have biased the results. Third, the important covariates such as antenatal care, knowledge about contraceptives that previous studies [48, 61] found as an important predictor of abortion could not be used in this study due to data unavailability, and inclusion of these variables would have changed the results of the final regression model.
4.1. Policy and Programmatic Implications
This study has policy and program implications. The current study indicates the urgency to safeguard women from intimate partner violence and prevent abortion. The Nepalese health system could address this issue through violence screening and provision of counselling support [10, 45]. Integrating IPV screening through antenatal care visits or family planning services at the health facility could be important steps to identify and offer counselling services to those who have experienced IPV . Furthermore, the government should implement comprehensive reproductive health interventions to reduce risk factors for unintended pregnancy and address the need of the women who are suffering from violence . Raising awareness among married women and providing social support would also help to better equip and prepared to deal with such challenging circumstances . The engagement of intimate partner (mainly those with alcohol drinking habit) in education and counselling program is crucial. In addition, the existing government law for protecting women from abuse and violence must be strictly implemented.
Intimate partner violence was associated with abortion among women in Nepal. This study concludes that pregnant women who experience IPV in Nepal are more predisposed to have abortion. It is imperative that public health intervention, including the early screening, identification, and timely management of IPV. Therefore, along with the provision of a range of contraceptives, maternal health service sites need to be strengthened to cater assessment, counselling, and referral services for IPV to reduce unintended pregnancy that ends in abortion in Nepal.
Data used in this study are publicly available secondary data obtained from the DHS (https://dhsprogram.com/data/available-datasets.cfm) program.
