Background
Domestic violence, known as the most common type of gender-related violence, is of particular social and health concern [
1]. Domestic violence against women encompasses any physical, sexual or emotional abuses imposed upon women in family relationships [
2,
3]. A recent comprehensive review published by the World Health Organization in 2013 reported that ‘the global prevalence of physical and/or sexual intimate partner violence among all ever-partnered women was 30 %. The prevalence was highest in the WHO African, Eastern Mediterranean and South-East Asia Regions, where approximately 37 % of ever-partnered women reported having experienced physical and/or sexual intimate partner violence at some point in their lives’ (a total of 185 studies from 86 countries included and data from 155 studies in 81 countries provided the estimates) [
4]. The review reported the following health effects of intimate partner violence: HIV and other sexually transmitted infections, induced abortion, low birth weight and prematurity, harmful alcohol use, depression and suicide, non-fatal injuries, and fatal injuries.
There is evidence that women may be more vulnerable to abuse during pregnancy and the postpartum period. As such it is argued that pregnancy not only does not provides security from intimate partner violence but also increases the risk of abusive relationships [
5,
6]. A systematic review of the literature on violence against pregnant women in developing countries found that prevalence of violence among pregnant women ranged from 4 % to 29 % and the main risk factors for abuse were low-income, low education in both partners, and unplanned pregnancy [
7]. The review included 6 studies from India, Pakistan, China and Ethiopia. All studies were cross-sectional in nature and all together studied 120421 pregnant women.
There is evidence that violence against pregnant women in Iran is high. For instance a study of 313 pregnant women found that 55.9 % of women had experienced violence during pregnancy including psychological violence (43.5 %), physical violence (10.2 %), and sexual violence (17.2 %) [
8]. Also, it has been shown that violence against pregnant women might differ in different geographical areas in Iran. A study from West Azerbaijan Province with a sample of 1300 pregnant women aged 18–39 years found that 72.8 % of women reported that they had experienced IPV during their last pregnancy [
9]. A recent study from Mazandaran Province (Northern Iran) studying 301 pregnant women aged 15–45 years found that 34.5 % of pregnant women had experienced psychological violence, 28.2 % physical violence, and 3.6 % sexual violence [
10]. It seems that such observations reflect the fact that firstly violence against pregnant women in Iran is not confined to a defined geographical area and is prevalent through the country, and secondly depending on cultural differences that exist in different parts of the country (mostly related to gender role outlook), there might be some differences in prevalence of abuse.
Violence against pregnant women has several severe adverse effects not only on women’s health but also might harm the fetus. Several studies reported adverse outcomes including increase in fetal injury, perinatal death (prenatal death and early neonatal death), preterm birth, low birth weight, miscarriage, placental abruption, premature rupture of membranes, rupture of urethra, bleeding, prenatal hospitalization, infection, and adverse mental health consequences and maternal behavioral risks to perinatal outcomes including depression, anxiety disorders, post-traumatic stress disorder, suicide (attempts), delayed entry into prenatal care, poor maternal nutrition and use of tobacco, alcohol [
11‐
18].
A study examining types of abuse compared physical, psychological and sexual violence among samples of pregnant women and found that the psychological abused group had a higher risk of postnatal depression compared with non-abused group. They were also at a higher risk of thinking about self-harm and had significantly poorer mental health-related quality of life. Although unusual, the higher risks of postnatal depression and self-harm were not evident in the physical and/or sexual abused group [
19]. Thus it is not surprising if one believes that quality of life in pregnant women who are suffering from violence is a very important issue. Although recently the literature on violence against women during pregnancy is growing both from developed and developing countries [
20‐
26], studies on relationship between domestic violence and quality of life of abused women during and after pregnancy are scarce.
There are no published papers examining quality of life in Iranian women during pregnancy. The available studies examining quality of life in abused pregnant women suggest that the intimate partner abuse has short-term and long-term negative health consequences [
27,
28]. In a study comparing quality of life among four groups of women including pregnant women, it was found that the baseline quality of life of the victims of intimate partner violence was significantly impaired compared with the non-abused controls [
29].
In Iran the majority of women attend free antenatal care at their local, state, or teaching hospitals. During their pregnancy generally attend a minimum of 12 visits. There is no universal postnatal care provided to but women can attend the hospital or visit doctor if she or the baby are experiencing physical health issues. Husbands usually do not attend antenatal or postnatal appointments. The focus of the antenatal care is on the obstetric health of mother and baby. Little consideration is given to social factors that may also impact on mother’s and baby’s health such as physical or emotional abuse from a husband. Therefore, this study aimed to identify what proportion of pregnant women attending a large teaching hospital were experiencing physical or psychological abuse by their husbands and the impact of this abuse on their quality of life during pregnancy. To the best of our knowledge this study is among a few existing literature that focus on health-related quality of life in pregnant women who had experienced violence. It was hoped that the findings from this study might contribute to the literature on the topic and perhaps provide evidence for developing appropriate services and practical therapeutic programs in health care centers and clinical settings.
Discussion
We found that a considerable number of pregnant women were exposed to intimate partner violence. The findings confirm previous observations from Iran [
7‐
9] that are alarming and needs urgent attention for providing support services for victims. Consideration of effective ways to prevent and address such violence against women is important, not only for women’s health, but also that for the health of their unborn baby and any other children in the family. A recent study from Iran showed that women with lower education and living in low income households reported more intimate partner violence during pregnancy than well-educated and affluent women [
32]. Such findings suggest that providing equal opportunity for women by legal and official means should be considered seriously in Iran and countries with similar conditions.
This study investigated quality of life in three groups of pregnant women and the findings indicated that psychological violence could have significant association with women’s quality of life as much as physical violence. This study highlights the fact that the physical violence impacts on women’s lives, but psychological abuse also significantly affects pregnant women’s physical and mental health. It is argued that physical abuse is an apparent phenomenon [
1] but psychological violence might not be detected very easily. A recent publication on intimate partner violence before and during pregnancy found that 14.9 % of women experienced psychological abuse while only 2.5 % of women reported physical abuse [
33]. Thus it seems that screening for psychological violence against pregnant women should be integrated into antenatal care services to support the health and well being of women and their families. As suggested health care providers are urged to identify those women at risk so that antenatal care can be tailored to best support optimal maternal and neonatal outcomes [
34]. However, one might argue that pregnant women are usually reluctant to disclose intimate partner violence to the healthcare team. Fortunately a recent review on screening women for intimate partner violence in healthcare settings indicated that pregnant women in antenatal settings may be more likely to disclose intimate partner violence when screened [
35].
There have been several studies on the impact of domestic violence on different aspects of women’s life during pregnancy [
23‐
26,
36]. Thus it is argued that deeper understanding is needed to indicate the actual impact of this complex matter. For instance a qualitative study found that ‘struggling to survive for the sake of the unborn baby’ was the main concern of women who were exposed to intimate partner violence during pregnancy [
37] or a study on midwives experiences reported that ‘it is difficult to recognize domestic violence’ because of a limited knowledge of the most common signs and symptoms of violence, a lack of training, cultural taboos, and the women׳s unwillingness to disclose abuse [
38]. We feel similar situation exist in Iran and antenatal care team usually do not ask pregnant women about domestic violence and even if they do so there is no way to get support for such victims. We believe young, and less educated women are more likely to suffer from intimate partner violence during pregnancy. Therefore we suggest the antenatal care team should take responsibility and make themselves familiar with the issue and at least find ways to support high-risk groups.
Limitations
The current study showed a significant difference in quality of life between abused groups (physical and psychological) and non-abused group. Yet, the results could not be generalized to all women since this was a descriptive study in nature with a limited sample size and even our exclusion criteria would exclude a large number of abused women as these criteria were closely associated with domestic violence. In addition we used a general questionnaire for measuring quality of life while it seems that more specific measures are required in order to explore the influence of different types of abuse on women’s quality of life and their mental health. Furthermore it is difficult to measure general and mental health if one does not ask about women’s health before pregnancy, especially mental health, as we did not. A new study provides good evidence for the importance of this [
39]. Finally, we know that the SF-36 has Physical and Mental Health Component Summary. Unfortunately we did not have access to the SF-36 software to calculate theses and thus we used the general and the mental health subscales instead. This also should be seen as a limitation.
