Depression, posttraumatic stress disorder (PTSD) and their comorbidity: Implications of adversity amongst young women living in informal settlements in Durban, South Africa

Cluster randomized controlled trial of Stepping Stones and Creating Futures to reduce mental health challenges among young men in informal settlements in KwaZulu-Natal Province, South Africa

BACKGROUND

Informal settlements are high density areas in and around cities, characterized by a lack of formal planning and basic amenities, being known in South Africa for high levels of mental disorder driven by violence, and complex social and economic challenges. In particular, young men's poor mental health goes untreated, with relatively few evidenced-based interventions available in this setting.

AIM

This cluster randomized controlled trial investigated the effectiveness of Stepping Stones and Creating Futures (SS/CF), a participatory gender transformative and economic empowerment intervention, on the mental health of young men living in South African informal settlement.

METHODS

A total of 674 young men ages 18 to 30 years were recruited in 34 clusters in Durban's urban informal settlements. Clusters were randomly allocated (1:1) to either the experimental SS/CF or control arm and participants were followed-up over 24-months. Intention-to-treat analysis based on generalized estimating equations (GEE) were fitted to quantify the impact of SS/CF on the men's anxiety and post-traumatic stress (PTS) symptomatology.

RESULTS

At end of the 24 months follow-period, anxiety (adjusted odds ratio [aOR]: 0.62, p = .04, 95% CI [0.39, 0.99]) and PTS (aOR = 0.52, p = .03, 95% CI [0.29, 0.93]) were significantly lower for group assigned to the SS/CF compared to the control group.

CONCLUSION

SS/CF, a gender transformative and livelihoods strengthening intervention designed to address poverty and other socio-economic challenges in informal settlements reduced anxiety and PTS among men with mental health challenges living in informal settlements.

High levels of poor mental health among young men in urban informal settlements in South Africa: a community-based study of social determinants

Informal settlements (high population density areas at the outskirts of urban areas characterized by lack basic amenities) in South Africa are consequences of apartheid regime's discriminatory migrant labour and spatial policy and continue to grow. Living in informal settlements accompanies a mire of social/health challenges that threatens upward mobility, but few studies exist that document drivers of mental health challenges in these settings. We investigated the prevalence and social determinants of poor mental health for young men in informal settlements adjacent to one of the largest cities that is at the heart of HIV endemic in South Africa. This study involved a cross-sectional study with cluster sampling design of 674 young men aged 18-30 years residing in eThekwini informal settlement communities. We assessed the prevalence, and social determinants, of significant depressive (i.e., depression) and post-traumatic stress (i.e., PTS) symptoms using logistic regression. Given the complex survey design of the study, all analyses were adjusted for clustering. The prevalence of depression and PTS in the sample was 46.8% and 14.4% respectively. Results of the multivariable analyses indicated that severe food insecurity (aOR = 2.98, 95% CI:1.70-5.22), crime perpetration (aOR = 1.51, 95% CI:1.05-3.80), severe adverse childhood event (aOR = 2.00, 95% CI: 1.05-3.80), traumatic event exposures (aOR = 2.43, 95% CI:1.56-3.80) and problematic alcohol use (aOR = 1.73, 95% CI:1.20-2.49) were significantly associated with depression. While incomplete secondary education (aOR = 0.45, 95% CI:0.22-0.92), moderate food insecurity (aOR = 2.51, 95% CI:1.04-6.06), traumatic event exposures (aOR = 2.19, 95% CI:1.32-3.64) and problematic alcohol use (aOR = 2.15, 95% CI: 1.24-3.73) were significantly associated with PTS. Our study highlights the exceedingly high levels of poor mental health among young men in informal settlements, with depression and PTS being driven by economic/social conditions. Multilevel interventions that address the individual, interpersonal, and social variables that contribute to poor mental health are needed.

The mediating role of post-traumatic stress disorder symptoms in the relationship between childhood adversities and depressive symptoms in two samples

BACKGROUND

Childhood adversities have been increasingly recognized as a significant risk factor for depression. However, the underlying mediating mechanism between childhood adversities and depression requires further investigation. The literature shows that childhood adversities are also closely associated with post-traumatic stress disorder (PTSD) symptoms and that PTSD symptoms can predict depressive symptoms. It remains unexplored whether PTSD symptoms can act as a mediator between childhood adversities and depression.

OBJECTIVES

The primary goal of this study was to examine whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms.

PARTICIPANTS AND SETTING

We examined in a convenience sample of Hong Kong adults aged 18 or above (N = 418) whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms. We then examined and compared the results with those in another convenience sample of Chinese-speaking young adults (mainly from Taiwan and Hong Kong) aged between 18 and 24 (N = 205). Participants in both samples completed online surveys that included measures of childhood adversities, PTSD symptoms and depressive symptoms.

RESULTS

Childhood adversities were significantly associated with depressive symptoms; and this relationship was mediated by PTSD symptoms in both samples.

CONCLUSION

This study is one of very few studies demonstrating that PTSD symptoms mediate the relationship between childhood adversities and depressive symptoms. Our findings suggest that addressing unresolved PTSD symptoms for adults with childhood adversities may help in preventing or treating depressive symptoms. Therefore, PTSD symptoms should be taken into account in the prevention and management of depression.

Post-traumatic stress disorder and associated factors among people who experienced traumatic events in Dessie town, Ethiopia, 2022: A community based study

BACKGROUND

Posttraumatic stress disorder (PTSD) may develop as a serious long-term consequence of traumatic experiences, even many years after trauma exposure. Dessie town residents have experienced prolonged armed conflict due to inter-communal conflict in 2021. Those people are exposed to different kinds of trauma, and violence, making them more prone to psychological disorders. Despite the highest number of people affected due to conflict and its negative impact on mental health, post-traumatic stress disorders among people are overlooked in Ethiopia. This study aimed to assess the prevalence and associated factors of post-traumatic stress disorder among people who experienced traumatic events in Dessie town, Ethiopia, 2022.

MATERIALS AND METHODS

Community based cross-sectional study was conducted on June 8-July 7, 2022, by using a multi-stage cluster sampling with a total sample of 785. Pretested, structured questionnaires and face-to-face interviews were used for data collection. PTSD was assessed by the Post-traumatic stress disorder Checklist for DSM-5 (PCL-5). Data was entered using Epi-data version 3.1 and, then exported to SPSS version 26 for analysis. The association between outcome and independent variables was analyzed with bi-variable and multivariable logistic regression. P-values less than 0.05 was considered statistically significant.

RESULT

The prevalence of PTSD among Dessie town residents was found to be 19.4% (95% CI, 16.7, 22.0). In multivariable analysis, being females (AOR = 1.63, 95% CI 1.10-2.44), previous history of mental illness (AOR = 3.14, 95% CI 1.14-7.06) depressive symptoms (AOR = 3.12, 95% CI 1.92-5.07), witnessing a serious physical injury of a family member or friend (AOR = 2.82, 95% CI 1.18-6.70) and high perceived life threats (AOR = 5.73, 95% CI 3.05-10.78) were found to be significant predictors of PTSD.

CONCLUSION

The prevalence of PTSD among Dessie town residents was found to be huge. Being female, having a previous history of mental illness, depressive symptoms, witnessing a serious physical injury of a family member or friend, and high perceived life threats were variables that are independent predictors of PSTD. People who have experienced such a severe traumatic event require psychosocial support to aid in their recovery from the terrible experiences.

Posttraumatic Stress Disorder, Suicidal Behavior, Substance Use, and Sexual Victimization Among Adolescent Girls Aged 10-19 Years Living Under Ethnic-Based Civil War in Ethiopia

BACKGROUND

Posttraumatic stress disorder (PTSD) is a chronic, impairing mental disorder that develops after exposure to a traumatic event. Despite many factors putting adolescent girls at risk of PTSD, little is known about the prevalence and how adolescent girls cope with the PTSD burden. So, this study aimed to investigate the prevalence of PTSD and associated factors among adolescent girls in three selected towns in Southwest Ethiopia.

METHODS

A community-based cross-sectional study was conducted among 397 adolescent girls from May 27 to July 27, 2021. The participants were selected by a systematic random sampling method. PTSD and substance use disorder were assessed by DSM V criteria for mental disorders. The data was entered into Epi Data Manager Version 4.0.2 before being exported to SPSS Version 25 for analysis. A logistic regression model was used, and variables with a p-value less than 0.05 in the final fitting model were stated as independent predictors of PTSD.

RESULTS

The prevalence of PTSD among the adolescent girls was 22%, and about three in four (72.7%) of the adolescent girls developed PTSD after exposure to sexual violence. Furthermore, PTSD was associated with Khat use disorder (AOR, 95% CI: 2.79 (1.47-5.30), alcohol use disorder (AOR, 95% CI: 5.27 (2.21-12.60), and suicidal behavior (AOR, 95% CI: 2.12 (1.20-3.74)).

CONCLUSION

The prevalence of PTSD was high among adolescent girls, and suicidal ideation or attempt, khat use disorder, and alcohol use disorder were risk factors for PTSD. Therefore, early screening for PTSD and comorbid risk factors among this particular age group and managing accordingly is warranted.

Investigating post-traumatic stress disorder (PTSD) and complex PTSD among people with self-reported depressive symptoms

BACKGROUND

Trauma has been increasingly linked to depression. Previous studies have suggested that comorbid post-traumatic stress disorder (PTSD) may be associated with poor outcomes in depression treatment. However, the prevalence and correlates of ICD-11 PTSD and complex PTSD (CPTSD) in people with depression remain unclear.

METHODS

This study examined the prevalence and correlates of ICD-11 PTSD and CPTSD in an online convenience sample of 410 adults from 18 different countries/regions who reported clinically significant levels of depressive symptoms (indicated by a Patient Health Questionnaire-9 score ≥10).

RESULTS

According to the International Trauma Questionnaire results, 62.68% of participants met the ICD-11 criteria for PTSD/CPTSD (5.6% PTSD, 57.1% CPTSD). Participants with CPTSD reported more types of trauma and higher levels of interpersonal stress than those without PTSD. Participants with CPTSD also reported higher levels of mental health problems, including depressive, dissociative and psychotic symptoms, than those without PTSD. Only disturbances in self-organization (DSO) symptoms but not classical PTSD symptoms had a significant relationship with depressive symptoms, when other major variables (including trauma, interpersonal stress, and comorbid psychotic and dissociative symptoms) were controlled for.

CONCLUSIONS

Trauma-related symptoms should be regularly screened for in clients who report depressive symptoms. Depressed clients who have comorbid trauma disorders have more trauma and interpersonal stress and exhibit more severe mental health problems. They may require specific trauma-focused interventions in addition to standard depression treatments.

Prevalence and factors associated with PTSD among female urban slum dwellers in Ibadan, Nigeria: a cross-sectional study

BACKGROUND

Little is known about the prevalence of and factors associated with PTSD among adult females in Nigeria, particularly those who live in slums. PTSD is a mental health condition that develops among some individuals who experience or witness a traumatic event. Several other factors could place individuals at heightened risk of PTSD including stress and comorbid mental disorders. Therefore, this study aimed to examine the prevalence and factors associated with PTSD among female urban slum dwellers in Ibadan, Nigeria.

METHODS

We conducted a cross sectional survey using multistage sampling of 550 women aged 18 and above from selected slums. Interviewer administered questionnaires were used to elicit information on experience of childhood trauma, recent stressors, intimate partner violence, other mental disorders, sociodemographic characteristics and PTSD. PTSD was measured using the Harvard Trauma Questionnaire (HTQ) which is based on DSM IV. A multivariable linear regression model was built to test associations between PTSD and independent variables.

RESULTS

The prevalence for PTSD was found to be 4.18% and the mean PTSD score was 5.80 ± 7.11. Sexual abuse in childhood, past year intimate partner violence and anxiety were significantly associated with higher PTSD scores. PTSD was not significantly associated with a history of recent stressors. Education, employment and marital status were not associated with PTSD however, age and wealth index showed marginal association with PTSD.

CONCLUSION

The prevalence of PTSD among women living in Ibadan slums was relatively low. Both child sexual abuse and intimate partner violence can be prevented. We also recommend longitudinal studies to better understand risk and protective factors.
