Pregnancy, childbirth, and transition to parenthood are normal physiological processes that are accompanied by important social and emotional conflicts for any woman and her family (
1). Most healthy women in developed countries should be able to experience childbearing as a positive life event that has very few adverse consequences (
2). Although most of women have good health in Western countries, the rate of childbirth interventions such as cesarean- section is high among them; for instance, the rate of cesarean delivery was 32.8% in the United States in 2012 (
3). According to information obtained from Lorestan University of Medical Sciences, the rates of cesarean delivery in social security, private, and public centers were 43%, 93%, and 39%, respectively, in Khorramabad and 44% in Lorestan province. In Iran, the rate of cesarean delivery is 3 times as high as the world average (
4), and with a prevalence of 45.55%, it is considered among the countries at risk for cesarean delivery (
5). Furthermore, studies show that only 15% of deliveries need a cesarean- section (
6-
8).
Many studies reported the most common reason for choosing cesarean delivery by women who have not experienced childbirth is the fear of childbirth. The prevalence of fear of childbirth has been reported as 5% to 30% in Sweden, Switzerland, and Australia (
9-
14). Approximately 6% to 10% of women experience an intense fear of labor and birth that is debilitating and disrupts the labor process (
9,
15,
16). According to a study conducted on primiparous women in Tehran, 74.3% of women selected cesarean- section due to fear of labor pain (
17).
Fear of childbirth in nulliparous women is more intense than in multiparous women (
11,
18,
19). According to previous studies, if a pregnant woman experiences a higher fear of childbirth in the third trimester of pregnancy for whatever reason, the risk of cesarean- section increases, even if she is physically healthy. In women with tokophobia, the demand for abortion or a cesarean- section is the only way to avoid fear (
20,
21).
According to various studies, personal and external conditions (environmental and contextual) play an important role in causing the fear of childbirth. Personal conditions reflect women’s concerns about maintaining a sense of personal control. In a study, of the 100 women who suffered an intense fear of childbirth, over 65% were worried about their performance in labor and their bodies’ abilities to give birth (
22). These concerns were attributed to having little hope for overcoming the labor and achieving positive outcomes (
23,
24). External conditions refer to the environment and context, where women give birth, and their interactions with health care professionals. For example, a study reported the lack of trust in the obstetric staff as the most common cause of fear of childbirth (
9).
Fear of childbirth in multiparous women can be related to the previous experience of traumatic or negative delivery (
12,
25-
27). Although delivery is considered to be a natural phenomenon, women's labor experiences are not only dependent on interventions and medical complications during labor, but also are related to their traumatic and negative experiences (
28,
29). Studies have shown that when women have pain during labor, it is highly important for them how the personnel deal with them (
29-
31).
Some women appear to be at greater risk for the experience of fear of childbirth compared to others. Sociodemographic characteristics such as low educational level, lack of social support, marital dissatisfaction, being young, unemployment, and having heard bad stories about pregnancy and childbirth are associated with fear of childbirth (
14,
18,
32-
34). Other risk factors include the history of negative experience of delivery, operative delivery, emergency Cesarean section, violence, and sexual abuse (
11,
12,
35,
36).
Women with anxiety disorders and depression are at greater risk for experiencing fear of childbirth (
14,
18,
34). Moderate to severe level of fear of childbirth is associated with some anxiety disorders such as panic and post-traumatic stress disorder (
37). Some characteristics such as fear of pain and low level of pain tolerance are also known as the causes of fears of childbirth (
13,
32,
38). Some other reasons include fear of mother’s death, fear of losing control, or fear of expressing stupid behaviors during labor (
32).
Other psychological and social factors affecting the fear of childbirth include fear of the unknown, desire for pain relief, physical and mental relaxation, mother’s personality traits, genetic background that makes a person vulnerable to stress, unpleasant experience and receiving encouragement from others, concern about adverse complications for mother, inappropriate behavior of the medical staff, fear of dying and being alone, concern about the health of the baby, lack of adequate social support, being young, unemployment, and low education and income. The fear of labor pain is also a predictive factor of pain during labor that may increase the risk of emergency cesarean- section and the rate of elective cesarean-section (
9,
15,
27,
34,
39,
40).
The results of studies on the causes of fear of childbirth show that many women are afraid of childbirth because they have no control over the actions which they are supposed to do. This causes the physiological process of labor to be transformed into a medical problem (
32).
Known physical and emotional consequences associated with fear of childbirth include voluntary infertility, pregnancy complications, increased use of analgesics during labor, increased labor interventions, increased duration of labor (
41), increased elective and emergency cesarean- sections, postpartum depression, post-traumatic stress disorder (PTSD), and impaired mother-infant bonding. The role of a woman as a mother and her relationship with her infant, other children, and the husband are influenced by these consequences (
9,
16,
29,
42,
43).
It seems that the current situation should be investigated to design and implement appropriate intervention programs and provide strategies to promote women’s health. The aim is to provide the best possible preventive strategies by determining the fear of childbirth among women and analyzing the relevant factors. Therefore, this study was conducted to determine the prevalence of fear of childbirth and its associated factors in primigravid women in Khorramabad, Lorestan province, Iran.
