Post-traumatic stress disorder among Iranian women with genital mutilation: a cross-sectional study

This cross-sectional study was conducted on 155 women with FGM/C referred to the health centers of Mahabad, located in west of Iran, from October 2020 to April 2021. The inclusion criteria were women with FGM/C aged 18–45 years. The exclusion criteria included current pregnancy and breastfeeding, having any known physical or mental disease, and history of traumatic events during the last six months.

The sample size was calculated 155 subjects using the formula \(\mathrm{n}=\frac{{\mathrm{Z}}_{1-\frac{\mathrm{\alpha }}{2}}^{2} {\delta }^{2}}{{\mathrm{d}}^{2}}\) and based on the PTSD variable in the study of Bahari et al. [15] and considering SD = 7.1, d = 0.05 around the mean = 22.3, α = 0.05 with 95% confidence coefficient.

The sampling was done using the convenience sampling method. The first researcher attended the health centers, extracted the telephone numbers of the women from the health records, checked the inclusion and exclusion criteria during the telephone call, and invited the eligible women to participate in the study. The women willing to participate in the study were invited to attend health centers to complete the written informed consent form. Then, the first researcher (a female midwife) in the presence of a female gynecologist determined the type of genital mutilation, according to WHO classification [2]. Women’s height and weight were measured and body mass index (BMI) was calculated as weight (kg)/ height²(m) [16].

The demographic and obstetric characteristics included the variables of age, duration of marriage, number of children, level of education, occupation, family income, type of residence, type of delivery, etc.

The symptoms of PTSD were assessed using PCL5, developed in 2013. PCL5 consists of four domains, including criterion B (re-experiencing symptoms), criterion C (avoidance of stimuli), criterion E (negative alterations in mood or cognition), and criterion D (arousal or reactivity). PCL5 includes 20 items, rating from 0 to 4 and total score range is between 0 and 80. The cutoff point of 33 is important for clinical diagnosis [17]. The Cronbach’s alpha coefficient of this instrument was reported as 0.91–0.94 and the test–retest reliability of the instrument was obtained 0.82 [18]. Cronbach’s α and the test–retest results for the Persian version of the questionnaire were more than 0.70 [19].

The data were analyzed using SPSS/21 software. The Kolmogorov–Smirnov test was used to measure the normality of data distribution. The independent t-test, Pearson correlation coefficient, and ANOVA were applied for data analysis. In order to control the confounding variables, the independent variables with P- value lower than 0.2 in the bivariate test were entered into the multivariate linear regression model using Backward strategy.

All 155 married women (100%) had type 1 genital mutilation. The mean (SD) age of participants was 31.46 (6.94) year. The minimum age at FGM/C was two years and the maximum age was ten years. Most of the participants (78.7%) had undergone FGM when they were aged 4 to 8 years old. The educational level of most of the participants (49.7%) was high school and diploma and most of them (77.4%) were housewives. The majority of women (61.9%) reported their family income as inadequate. There was no significant difference in the mean score of BMI between the two groups (Table 1).

In this study, six women (3.9%) had PTSD. The mean (SD) score of the PTSD symptoms among the women was 27.73 (6.79) in the attainable score of 0–80. The mean (SD) of re-experiencing symptoms was 6.12 (2.7) in the obtainable domain score of 0–20. The mean (SD) of the avoidance of stimuli was 4.78 (2.24) in the achievable domain score of 0 to 8. The mean (SD) of the negative alterations in mood or cognition was 9.38 (3.38) in the attainable domain score of 0–28. Further, the mean (SD) of the arousal domain was 7.45 (2.62) in the obtainable domain score of 0 to 24. Then, the average standard score of the different domains was estimated based on the following formula:

Accordingly, the lowest complaint was related to the re-experiencing symptoms with a modified mean of 30.6 and the highest complaint was associated with the avoidance of stimuli with a modified mean of 59.75 (Table 2).

The bivariate tests showed a significant relationship between PTSD score and mutilation age (P = 0.016), body mass index (P = 0.038), education (P = 0.015), and type of residence (P = 0.002) (Table 1). After entering variables with p < 0.2 in the multivariate linear regression model, the predictors of PTSD severity included age at FGM/C, education, and type of residence, which generally explained 48.1% of the variance (Table 3).

The results of the present study indicated that six women (3.9%) had PTSD. The mental health status of 66 circumcised women migrating from Africa to the Netherlands was investigated in a study conducted in 2012 and the results indicated that about 54% of participants had type III FGM, 14% type II and 32% type I. Further, approximately, 16% of circumcised women had the symptoms of PTSD [20]. In another study, 17.5% of African women with genital mutilation had PTSD symptoms [21]. The results of a study performed in Egypt indicated that 19% of women with genital mutilation exhibited symptoms of PTSD [22]. Further, the prevalence of PTSD among circumcised women was reported to be 30.4% in a study conducted in Senegal [23]. In most of studies, the prevalence of PTSD was not reported by the type of FGM/C and only a few studies stratified the results based on FGM/C type [5, 21, 23]. The prevalence of PTSD in the present study is much lower than the prevalence reported in various studies with the same sampling method, which may be due to the high prevalence of type I of FGM/C in the study area. On the other hand, the acceptance of FGM/C among the study population may be acted as a protective factor against PTSD. Early studies also reported that the prevalence of psychological trauma and PTSD increases in societies with low prevalence of FGM/C and its social rejection [14, 22].

In the present study, the mean (SD) score of PTSD symptoms among Kurdish women with type 1 of FGM/C was 27.73 (6.79). In a study performed in north of Iraq [24], sharing borders with Iran, the mean (SD) score of PTSD among circumcised Kurdish girls aged 8–14 years was 44.3 (13.73) and the severity of symptom was very high compared to the findings of the present study, which may be attributed to the low prevalence of FGM/C in the north of Iraq, differences in the age groups, and not stratifying the results based on FGM/C type. The study population in the aforementioned study was single girls with a mean age of 12.2 years and in the present study was married women with a mean age of 31.46 years. Further, in a study conducted in Kenya [25], the mean score of PTSD symptoms among women with genital mutilation migrating from Somalia was 41.16 (16.1), as these refugee women had experienced many difficulties and challenges before, during, and after migration, they were more likely to experience higher levels of PTSD. In the present study, the severity of PTSD among the participants were relatively low, which may be due to convenience sampling of the study, the limited injury in genitalia and the social acceptance of the practice.

In the present study, the age at FGM/C was regarded as the predictor of PTSD among the women. Namely, individuals who were older at the time of genital mutilation exhibit more PTSD symptoms. Consistent with the findings of the present study, the results of a study conducted on Somali women revealed a positive relationship between the age at FGM/C and PTSD symptoms [25]. Vloeberghs et al. [20] also reported that the severity of PTSD symptoms was higher among women who were older at the time of genital mutilation.

In addition, the level of education and type of residence were considered as other predictors of PTSD in the present study, so that the severity of PTSD symptoms increased among women with lower level of education and those who live in the house of the father-in-law. In fact, circumcised women with low social and economic status demonstrated more PTSD symptoms. Knipscheer et al. [21] reported that the low economic status was significantly associated with psychological trauma among circumcised girls and women, which is in line with the results of the present study. Further, Vloeberghs et al. [20] addressed that full housewife women experienced more anxiety and depression compared to the employed circumcised women.

The strengths of the present study included using standard questionnaire and reporting the results in detail for type 1 FGM. Moreover, the findings of the study provided evidence for planning a future advanced study. The main limitation of study is the use of the convenience sampling method. Also, the results of the present study cannot be generalized to other contexts or cultures, since it was conducted in one geographical area with specific ethnicity.
