Determinants of intimate partner violence during pregnancy among married women in Abay Chomen district, Western Ethiopia: a community based cross sectional study.

BACKGROUND: Intimate partner violence during pregnancy is the most common form of violence that harms the health of women and the fetus but practiced commonly in developing countries. There is scarcity of information regarding intimate partner violence during pregnancy in Ethiopia. Thus, this study aimed to assess the prevalence and associated factors of intimate partner violence during recent pregnancy in Abay Chomen district, Western Ethiopia.
METHODS: Community based cross sectional study was conducted among married pregnant women in Abay Chomen district in April, 2014 using a standard WHO multi-country study questionnaire. Two hundred eighty two randomly selected pregnant women aged 15-49 years participated in the study. Logistic regression and multivariate analysis were employed.
RESULTS: The prevalence of intimate partner violence during recent pregnancy was 44.5% (95% CI, 32.6, 56.4). More than half 157 (55.5%) experienced all three forms of intimate partner violence during recent pregnancy. The joint occurrence of intimate partner physical and psychological violence during recent pregnancy as well as joint occurrence of intimate partner physical and sexual violence was 160 (56.5%). Pregnant women who were ever lived with their partner's family were 46% less likely to experience recent intimate partner violence. Dowry payment decreases intimate partner violence during recent pregnancy (AOR 0.09, 95% CI 0.04, 0.2) and pregnant women who didn't undergo marriage ceremony during their marriage were 79% are less likely to experience violence (AOR 0.21, 95% CI 0.1, 0.44).
CONCLUSION: Nearly half of interviewed pregnant women experienced intimate partner violence during pregnancy implying the prevalence of such practice in the study site. To that end, increasing community awareness about the consequences of the practice could be important. Moreover, as health extension workers works closely with households, they could be crucial players to increase community awareness about intimate partner violence on pregnant mothers and halt it or its risk factors.

Background

Declaration on the elimination of violence against women defines violence against women as “…any act of gender-based violence that results in, or is likely to result in, physical, sexual or psychological harm or suffering to women, including threats of such acts, coercion or arbitrary deprivation of liberty, whether occurring in public or in private life” [1]. By year 2013, one out of three women experienced violence [2]. Among those violence, intimate partner violence on pregnant women is a global health concern [2]. The WHO multi-country study on women’s health and domestic violence against women found the prevalence of physical intimate partner violence as 15 % in Japan to 71 % in Ethiopia and the prevalence of physical domestic violence against women in pregnancy 1 % in Japan city to 28 % in Peru Province, with the majority of sites ranging from 4 to 12 % [3]. Prevalence of violence against pregnant women in developing countries is estimated to be 4 to 29 % [4].

Analysis of demographic and health surveys and the international violence against women survey showed prevalence of intimate partner violence during ‘pregnancy to be 2 % in Australia, Denmark, Cambodia and Philippines to 13.5 % in Uganda, with the majority 4 and 9 % [5].

In Ethiopia, community based studies indicated that 50 to 76.5 % of women experienced domestic/intimate partner violence in their life time [6-10]. Prevalence of intimate partner physical violence during pregnancy in rural Ethiopia is reported to be 8 % [3].

Intimate partner violence during pregnancy has been associated with fatal and non-fatal adverse health outcomes for the pregnant woman and her unborn fetus either direct physical trauma to her body and physiological stress from current or past abuse or fetal growth and development [11-15].

Different studies showed that intimate partner violence against pregnant women was significantly associated with adverse maternal health outcomes i.e. unintended pregnancies, pregnancy-related symptom distress, inadequate prenatal care, induced abortion, spontaneous abortion, gestational weight gain, intra uterine restriction, hypertension, pre-eclampsia, third trimester bleeding and STIs. Pregnant women were at higher risk of adverse outcomes including maternal death [16-18].

In low and middle income countries including Ethiopia, there are several gaps and inadequate evidence on prevalence and factors associated with intimate partner violence during pregnancy [4]. Most studies were limited to intimate partner violence to non pregnant women. However, the consequence of intimate partner violence during pregnancy is worse.

Thus, this study assessed magnitude and associated factors of intimate partner violence during pregnancy (IPVDP) in Abay Chomen district, western Ethiopia.

Methods

Study area

The study was conducted in Abay Chomen district, Oromia region, western Ethiopia. Abay Chomen district is located in Horro Gudurru Wollega Zone of Oromia region, 246 Km to the west of Addis Ababa, the capital city of Ethiopia. The district has two administrative towns and 18 rural kebeles, which is the smallest administrative unit in Ethiopia. There were five health centers and 18 health posts in the study area [19].

Study design and population

Community based cross sectional study was conducted in the district in April, 2014. Study population were randomly selected and pregnant women aged 15–49 years who are living in the study area for at least six months prior to the study were targeted.

Sample size was calculated using a single population proportion formula using the following assumptions; 8 % prevalence of intimate partner violence during pregnancy in rural Ethiopia (3) 95 % confidence level, 3 % margin of error, 10 % allowance for non-response rate. Accordingly, the total sample was 299.

Out of twenty one kebeles of Abay Chomen district, ten kebeles were randomly selected. Updated ANC registration of health extension workers was checked and household pregnant women census was done for one week by six interviewers and numbering was done in the selected kebeles to fix a sampling frame.

A total of 2021 pregnant women who lived at least six months prior to the study period were enumerated. Finally, population proportion allocation was done to identify respondents from the selected households as a study unit. In situations where households had two or more eligible subjects, only one was selected by lottery method.

Data collection method and tools

Data was collected by six high school completed female interviewers using standard WHO multi-country study of VAW questionnaire [20]. The questionnaire was translated to local language Afan Oromo by experts in both languages and was translated back to English by another person to ensure consistency and accuracy. The data collection process was closely supervised by two health officers and the principal investigator. The data collectors and supervisors were recruited based on previous experience on data collection and fluency in the local language. In addition, training was given for two consecutive days on how to interview, handling ethical issues and maintaining confidentiality and privacy. Pre-test study covered 15 pregnant women in a separate kebele, which become out of the main study.

Pre-test was conducted to familiarize enumerators with the administration of interview process and for ensuring consistency. Debriefing sessions were held with the pre test field staff and the questionnaires were modified based on lessons drawn from the pre -test.

Data analysis

Data was first checked manually for completeness and then coded and entered in to Epi data version 3.5.1. Then the data was exported to SPSS version 16.00 for data checking, cleaning and logistic regression. Cleaning was done by calculating frequencies and sorting. Bivariate analysis between dependent and independent variables was performed using binary logistic regression. P < 0.25 was used as criteria to select candidate variables for multivariate analysis. Multivariable logistic regression analysis was done to adjust for possible confounding variables. P-value < 0.05 with 95 % confidence interval (CI) for OR (odds ratio) was used in judging the significance of the associations. Results were presented in text, tables and charts.

Ethical considerations

Ethical approval was obtained from Ethical Review committee of Jimma University. Letter of permission was obtained from Abay Chomen district administration and health offices. The purpose of the study was explained to the study participants and written consent was secured before data collection was started and confidentiality of the information was ensured by coding. For study participants aged less than 18, we received written informed consent from the participants themselves because they were married and mature minor. The consent procedure was approved by the ethics committee for all including those aged less than 18 years [21]. The interview with the pregnant women was undertaken privately in separate area within the household compound and fieldworkers were trained to refer women requesting assistance to available sources of support according to WHO Ethical and safety recommendation [22]. However, no pregnant women requested support.

Factors associated with IPVDP

Result of binary logistic regression showed that childhood growth areas, partner’s education, partner’s age, age of marriage, age at first sex, ever lived with partner’s family, type of marriage ceremony, dowry payment, dowry impact in future life, having discussant to talk their problem, battering seen during childhood, support of pregnant women battering, money provision and marriage level were identified as significant predictors of experiences of IPVDP (intimate partner violence during recent pregnancy) while respondents’ educational status and occupation were not associated.

In multivariable logistic regression three variables i.e. dowry payment impact, partner education and undergoing marriage ceremony were associated. When compared with literates, illiterate partners were 50 % less likely to use violence against their intimate partner during recent pregnancy (AOR 0.5, 95 % CI 0.2, 0.9).

Pregnant women who reported that dowry payment has positive impact on how they are treated by their husband and his family were 8.7 times more likely to experience IPVDP than those who reported no positive impact on how they are treated by their husband and his family (AOR 8.7, 95 % CI 4.2, 17.9). Pregnant women who didn’t undergo marriage ceremony during their marriage were 4.1 times more likely to experience IPVDP (AOR 4.1, 95 % CI 2, 8.2) (Table 6).

Discussion

The study showed that intimate partner violence during recent pregnancy was 44.5 % which was consistent with study from Zimbabwe [23] and higher than studies conducted in USA [24], Japan, and South Africa. This could be because this study included psychological violence as an addition for measuring intimate partner violence during pregnancy [3, 25, 26] unlike the other studies. The higher prevalence found in this study also might indicate that women were disadvantaged segment of the population and the country’s patriarchal society norms.

About three in ten 82 (29.2 %) respondents experienced physical violence during recent pregnancy by their intimate partner. It is in agreement with study conducted in Namibia [3] and Tanzania. However, this finding is higher than finding from previous studies in Ethiopia and Serbia and Montenegro [3]. The possible reason might be the presence of traditional norms that support beating pregnant women in the study area because 32 (11.4 %) of the respondents reported that they support pregnant women to be battered by her intimate partner.

Likewise, in this study 13.4 % of pregnant women were beaten on their abdomen during pregnancy in which 86.2 % of the assailants were the biological father of the baby they were carrying, which is slightly higher than WHO finding which was 8 % [3]. This can be explained by inter cultural difference among the two study setting as they are south and west Ethiopia settings. Furthermore, it might be due to the fact that WHO study covered a large section of the population where as this study is in one district. The perpetrator, the biological father (86.2 %) of the baby she was carrying was lower than previous Ethiopian study [3]. This might be due to presence of polygamy in the study area because 37 (13.1 %) of respondents married to partners who had other wife.

One in three, 85 (30 %) of pregnant women had sexual violence during recent pregnancy. This is similar with study conducted in Tanzania [27] which might be due to shared similar socio economic status. It is higher than findings from Namibia [3]. This might be due to sexual autonomy imbalance among the two study areas.

Overall, the prevalence of psychological intimate partner violence during recent pregnancy was 46 (16.3 %) which is lower than study conducted in South Africa which was 49 % [28]. This could be due to difference in the perception of violence in the respective communities [29].

Women who ever lived with their intimate partner’s family were 45 % less likely to experience intimate partner violence during pregnancy when compared with women who had not ever lived with their partner’s family. This might be explained if pregnant women were attached to their husband’s family, their partner’s respect might increase and so lower violence.

Unlike other studies, compared with literates, illiterate partners were 50 % less likely to experience violence by their intimate partner during pregnancy. Pregnant women who reported that dowry payment has positive impact in the rest of their lives were 8.7 times more likely to experience IPVDP than those who reported no positive impact. Pregnant women who didn’t undergo marriage ceremony during their marriage were 4.1 times more likely to experience IPVDP.

Dowry impact on how they are treated by their husband and his family was also a risk factor for IPVDP as dowry is the payment to be made to the groom’s family to marry a daughter, and it takes different forms in different cultures. However, the size of the dowry is a common reason for disputes between the families, with the groom’s family demanding more than the bride’s family can offer, resulting in violence of brides even to death in India and southern Asian countries [30].

Conclusions

Intimate partner violence during recent pregnancy is observed in nearly half of the pregnant women in the study area. One in three pregnant women experienced both physical and sexual violence. More than one in ten experienced intimate partner psychological/emotional violence. The implication of the study findings regarding the practice of intimate partner violence during recent pregnancy is common in the study site. To that end, increasing community awareness about the consequences and its adverse reproductive health outcomes of the practice could be an important. Moreover, the health extension workers should be engaged in education, screening and referral of IPVDP victims as they are near to the community. In addition the district education office, office of women’s affair should strengthen education on prevention of intimate partner violence in schools. The unique finding from this study is about the association between education and intimate partner violence among pregnant women where it associated positively with less education. To make the associations of demographic variables more clear, we recommend further longitudinal studies to further strengthen the magnitude and associated factors and its effect on pregnant women and the fetus locally.

Moreover, the longitudinal study will help in checking the repeatability of the findings in different areas and with different study design possible to scale it up to incorporate in the government policy.
