The prevalence of post-traumatic stress disorder among women with normal vaginal delivery in Zahedan city

Abstract

Aim of the study: The study aimed to determine the prevalence of post-traumatic stress disorder (PTSD) among postpartum women in Zahedan city, Iran. Subject or material and methods: Data in this cross-sectional study were gathered from healthcare centres of Zahedan, a city in south-east Iran. Four-hundred women with childbirth experience over the past few months were selected; between 6 and 24 weeks had passed since their delivery. We used three questionnaires in order to evaluate the demographic data, PTSD symptoms and traumatic childbirth experience. Results: The mean parity was 3.40±2.55 children and the mean duration of pain was 19.44±9.16 hours. Overall, 7.8%, 36% and 0.5% of the subjects had a previous history of curettage, episiotomy and vacuum evacuation, respectively. In total, 32% of the participants showed PTSD symptoms. Prevalence of PTSD was not significantly associated with parity, pain duration, education level or employment status. Significant correlation with PTSD was found with the mode of delivery (P=0.013), curettage (P=0.005) and length of hospitalization. Also, prevalence of PTSD was substantially associated with the type of pregnancy (planned or unintended) (P=0.011). Discussion: Women with PTSD were not significantly different from those without PTSD in terms of parity, pain duration, education level or employment status. Conclusions: History of curettage, episiotomy and vacuum evacuation increased the incidence of PTSD in postpartum women. Moreover, unwanted pregnancy was more common among women with PTSD compared with normal subjects and length of hospitalization was longer.
