“…Numerous studies have identified a higher prevalence of PTSD among women ( Abeldaño et al, 2014 ; Hatori & Bhandary, 2022 ; Maya-Mondragón et al, 2019 ); however, our investigation did not detect any sex-related differences. The increased vulnerability of women to PTSD has been attributed not only to biological factors but also to variations in socialization processes and formative childhood experiences ( Abeldaño et al, 2014 ; Breslau & Anthony, 2007 ), in conjunction with exposure to trauma itself.…”

“…For instance, the Nepal earthquake of April 25, 2015, has been the subject of several studies, highlighting differences in prevalence rates depending on the timing and context of exposure. One study focusing on certain districts in the Kathmandu Valley found a prevalence of post-earthquake PTSD of 15.9% at 6 months ( Hatori & Bhandary, 2022 ), while another study focusing on other districts in the same region reported a prevalence of 5.2% at 4 months ( Kane et al, 2018 ). Differences in the socio-demographic composition of the samples and exposure context may explain some of these differences ( Hatori & Bhandary, 2022 ).…”

Post-traumatic stress (PTSD) disorder is a mental health condition that can occur after experiencing or witnessing a traumatic event. The 27-F earthquake that struck Chile in 2010 was one such event that had a significant impact on the mental health of the population. A study was conducted to investigate the prevalence of PTSD and its associated factors among survivors of this earthquake. The study was a longitudinal design, involving a sample of 913 patients aged 18 to 75 years who attended 10 Primary Care Centers in Concepción, Chile. The Composite International Diagnostic Interview (CIDI) was used to assess both depressive episodes (DE) and PTSD before and after the earthquake. The study also involved genotyping studies using saliva samples from the participants, specifically focusing on the Val66Met and 5-HTTLPR polymorphisms. Statistical analysis was performed to examine the association between different variables and the presence of PTSD. These variables included demographic factors, family history of psychiatric disorders, DE, childhood maltreatment experiences, and critical traumatic events related to the earthquake. The results showed that the incidence of post-earthquake PTSD was 11.06%. No significant differences were found between the groups of participants who developed post-earthquake PTSD regarding the Val66Met or 5-HTTLPR polymorphisms. However, a significant association was found between the concomitant diagnosis of DE and the development of post-earthquake PTSD. The presence of DE doubled the risk of developing post-earthquake PTSD. The number of traumatic events experienced also had a statistically significant association with an increased risk of developing post-earthquake PTSD. The study’s limitations include the potential interference of different DE subtypes, the complexity of quantifying the degree of earthquake exposure experienced by each individual, and events entailing social disruption, such as looting, that can profoundly influence distress. In conclusion, the study found that PTSD following the 27-F earthquake in Chile was associated with a concomitant diagnosis of DE and the number of traumatic events experienced. The study did not find a significant association between PTSD and the Val66Met or 5-HTTLPR polymorphisms. The researchers recommend that mental health professionals should prioritize the detection and treatment of concomitant depressive episodes and exposure to critical traumatic events in survivors of disasters. They also suggest that further research is needed to better understand the relationship between genetic factors and post-disaster PTSD.

However there are no studies comparing the prevalence of PTSD among SCI individuals with respect to their ethnicity or caste.…”

Study design: Cross-sectional studyObjectives: To identify the prevalence of posttraumatic stress disorder (PTSD) among the individuals with traumatic spinal cord injury (TSCI) and to examine the relationships between demographic and clinical characteristics, and PTSD.Setting: Spinal Injury Rehabilitation Center (SIRC) and Dhulikhel Hospital, Kathmandu University Hospital (DH, KUH), Kavrepalanchowk, Nepal.Methods: Individuals above18 years of age with TSCI of at least one month from trauma and admitted to SIRC and DH, KUH from June 2019 to May 2021 were included. The specific stress version of the Post-Traumatic Stress Disorder Checklist (PCL), a 17- item self-report instrument corresponding to DSM–IV criteria for PTSD was utilized. To classify the neurological status of TSCI individuals, American Spinal Cord Injury Association (ASIA) and International Standard for Neurological Classification of Spinal Cord Injury (ISNCSCI) were used. Hierarchical multiple regression analysis between independent variables and normalized PCL score was done to evaluate the predictors of PTSD.Results: Among 163 patients, the overall prevalence of PTSD was 27%, and the mean PCL score was 36±13.9. Factors predictive of PTSD included gender, family type, ethnicity, and literacy rate. No significant association was found between the clinical characteristics and PTSD.Conclusions: PTSD appears to be considerably prevalent among individuals with TSCI in Nepal. Females, individuals from nuclear families, individuals with lower literacy, and individuals from lower caste are significantly vulnerable to developing PTSD. However, clinical characteristics do not appear to be influential in the development of PTSD.
