Anger is an emotion that all individuals experience and it is considered a natural aspect of married life. Actually, it seems that the more relationships an individual has, the more opportunities for anger appearance. However, if this emotion is not controlled, it could lead to verbal and physical violence, harm intimate relationships, and finally to marital dissatisfaction and even separation and divorce.¹⁾ Studies show that women are subjected to violence 6 times more than men.²⁾

Domestic violence against women occurs in several forms such as physical, emotional, and sexual violence and is an important issue from the human health and rights perspective.^3,4) Domestic violence occurs in all countries, irrespective of the social, economic, religious, or cultural differences.²⁾

Although exact statistics are not available for the frequency of domestic violence against women, a previous study indicated that 20% to 50% of the women worldwide have experienced some form of domestic violence in their lifetime.⁵⁾ An Iranian study reported that 20.2% of Iranian women experienced physical violence at any given point of time. Additionally, the prevalence of psychological, sexual, and any type of violence were 41%, 10.9%, and 47.3%, respectively.⁶⁾

Previous studies have mentioned age,⁷⁾ education level,⁸⁾ occupation, ⁹⁾ family relationships between couples,¹⁰⁾ and religious beliefs¹¹⁾ as factors influencing domestic violence.

What is certain is that violence against women exists everywhere in the world, leading to adverse effects on their lives and marital relationships. ¹²⁾ Both physical and mental problems are important results of domestic violence.¹³⁾ Other consequences of domestic violence include injury and death,¹⁴⁾ effects on pregnancy outcomes and newborns, ¹⁵⁾ and women's mental health.¹⁶⁾ Women are the most important segments of the society and paying attention to their own health affects their family health.^17,18)

Ilam is one of the border provinces of Iran and the Ilamian people have experienced severe stress caused by the long years of war. Experiencing such stress may lead to psychological disorders among some people. Because there is a relationship between psychological disorders and the prevalence of violence, evaluating the prevalence of violence in this society is necessary. Considering the physical and psychological consequences of domestic violence against women the present study aimed to determine the prevalence and relative factors of domestic violence against Iranian women.

The present study investigated the prevalence and relative factors of domestic violence against Iranian women. Of every ten women who participated in this research study, 6 reported being abused by their husbands. This frequency is higher than the results of a previous study that claimed violence prevalence up to 50%.⁵⁾ However, another study reported that 75.9% of their study population was physically, psychologically, and sexually abused by their husbands.¹³⁾ The researchers believe that in some Iranian families, cultural and social issues have created conditions that men have a powerful position while women have a weak position in their family structure. Therefore, in such families women are vulnerable and fragile. In addition to the difference between the prevalence of violence against women in Iranian and international studies, differences exist in the reported prevalence even among Iranian studies. The prevalence reported in this study was higher than other Iranian studies^19,20) that showed that all types of violence against women ranged from 20% to 43%.²⁰⁾

Our results show that emotional violence had the highest prevalence; however, sexual violence had the lowest prevalence among our study population. In another study, 37% of the women reported the psychological violence, while 14% reported physical and sexual violence in their homes.²¹⁾

In traditional societies where men are considered superior to women and are responsible for the family life, there is a higher level of sexual violence against women.²²⁾ While, in societies where men consider women as their equals have lower rates of sexual violence against women.²³⁾

We found a statistically meaningful relationship between education level and occupation with respect to violence against women. The results of univariate logistic regression showed that the risk of violence against women was 3.1 times higher among illiterate women as compared to women with a master's degree education and the multivariate logistic regression indicated that risk of violence was 4.2 times higher. Additionally, multivariate logistic regression indicated that the risk of violence against women was 2.7 times higher among housewives compared to women who had government jobs.

Our results concur with Bolheri and Qhahary³⁾ who considered unemployment, having low levels of education, and low income as main effective factors of domestic violence against women. In line with our results, an Indian study reported a statistically meaningful relationship between education level and occupation with violence against women.²¹⁾ We did not find ant studies that yielded different results.

We found a statistically meaningful relationship between age when married, and duration of marriage with violence against women. In line with our results, an Indian study reported a statistically meaningful relationship between duration of marriage and violence against women.²¹⁾

Based on the results of our in multivariate logistic regression analysis, there is a statistically significant relationship between the number of children and violence against women. Specifically, the possibility of violence against women who did not have children was 1.9 times more than women who had more than 7 children.

A previous study has linked the number of living male children and domestic violence against women.²⁴⁾ Similar to our results, previous studies confirmed that higher the number of children is associated whit higher the violence against women.^25,26)

Our results demonstrated that the kinship with husband's family is a risk factor for domestic violence against women. Another study in line with our results, confirmed the relationship between, living with the extended family and domestic violence against women.²⁴⁾

Based the results of our multivariate logistic regression analysis, getting married early was a risk factor for domestic violence against women. Thus, the risk of violence against women was 5 times higher among women who were married when they were younger than 15 years than women who had married when they were older than 30 years. Possibly, the inability of young women to perform their duties and lack of communication skills leads to higher risk of domestic violence against young women. Other studies have also confirmed our results.^26,27)

The results of the present study showed that shorter duration of marriage is a risk factor for violence against women. Univariate logistic regression analysis indicated that the possibility of violence against women who had been married for less than 5 years was 5 times more than women who had been married for more than 30 years. This risk was 6.3 times using multivariate logistic regression analysis. In some Iranian families, marriages are still arranged traditionally. Hence, in such a marriage, a couple may not know each other very well. Therefore, an insufficient knowledge can led to high risk of violence against women in the early years of marriage. Recently a study in line with our results has confirmed the association between length of marriage and the risk of violence against women.²⁸⁾

Probably the men who have been abused in childhood are more likely than other men to commit violence against women.²⁹⁾ In the current study, data were not available about the husband's childhood history for women who were subjected to violence by their husbands. This is a limitation of the current study.

We could say that the high prevalence of wife abuse in Ilam especially emotional violence due to lower education levels and marriage at younger age could be a serious threat for women's health as well as for other members of the family. This could be a grounding factor for other social harms such as suicide and this issue must be studied from legal, religious, and cultural standpoints.
