Femicide, intimate partner femicide, and non-intimate partner femicide in South Africa: An analysis of 3 national surveys, 1999-2017.

BACKGROUND: In most countries, reliable national statistics on femicide, intimate partner femicide (IPF), and non-intimate partner femicide (NIPF) are not available. Surveys are required to collect robust data on this most extreme consequence of intimate partner violence (IPV). We analysed 3 national surveys to compare femicide, IPF, and NIPF from 1999 to 2017 using age-standardised rates (ASRs) and incidence rate ratios (IRRs). METHODS AND FINDINGS: We conducted 3 national mortuary-based retrospective surveys using weighted cluster designs from proportionate random samples of medicolegal laboratories. We included females 14 years and older who were identified as having been murdered in South Africa in 1999 (n = 3,793), 2009 (n = 2,363), and 2017 (n = 2,407). Further information on the murdered cases were collected from crime dockets during interviews with police investigating officers. Our findings show that South Africa had an IPF rate of 4.9/100,000 female population in 2017. All forms of femicide among women 14 years and older declined from 1999 to 2017. For IPF, the ASR was 9.5/100,000 in 1999. Between 1999 and 2009, the decline for NIPF was greater than for IPF (IRR for NIPF 0.47 (95% confidence interval (CI) 0.42 to 0.53) compared to IRR for IPF 0.69 (95% CI 0.63 to 0.77). Rates declined from 2009 to 2017 and did not differ by femicide type. The decline in IPF was initially larger for women aged 14 to 29, and after 2009, it was more pronounced for those aged 30 to 44 years. Study limitations include missing data from the police and having to use imputation to account for missing perpetrator data. CONCLUSIONS: In this study, we observed a reduction in femicide overall and different patterns of change in IPF compared to NIPF. The explanation for the reductions may be due to social and policy interventions aimed at reducing IPV overall, coupled with increased social and economic stability. Our study shows that gender-based violence is preventable even in high-prevalence settings, and evidence-based prevention efforts must be intensified globally. We also show the value of dedicated surveys in the absence of functional information systems.

Ntombi Vimbela! Sexual violence risk reduction intervention: pre and one-year post assessments from a single arm pilot feasibility study among female students in South Africa.

BACKGROUND: The extremely high prevalence of sexual violence victimisation reported among female students in South African public higher education demands urgent action to develop, rigorously evaluate and scale effective prevention interventions. This article details findings from a pilot feasibility study of Ntombi Vimbela! a campus sexual violence risk reduction intervention developed to tackle the high burden of sexual violence in higher education institutions in South Africa. METHODS: Ntombi Vimbela! (NV!) is a sexual violence risk reduction intervention that comprises sexuality empowerment, gender and social norm change, early-risk identification, self-defence, resistance and mental wellbeing components. NV! is comprised of ten workshop sessions running for 3.5 h each. Workshops are co-delivered by two trained peer facilitators per group of at most 20 first-year female students. One-year post-intervention quantitative outcome assessments were remotely completed by 98 participants who participated in the NV! pilot workshops. Qualitative assessments were conducted with 35 participants through in-depth telephone interviews (IDTIs). FINDINGS: One year after attending NV! workshops, most participants reported improved awareness of sexual rights, assertive communication, shifts in gender equitable beliefs, reductions in rape myth acceptance, improved expressed sexual relationship power sexual decision-making, and improved negotiation within their intimate relationships. Participants' depressive symptoms also significantly decreased. Many participants improved awareness of sexual assault risk and vigilance, including using self-protection strategies such as removing themselves from environments where alcohol intoxication posed sexual assault risks. Some participants used assertive communication to withstand peer pressure to engage in risky sexual behaviours. Most participants scored highly on the self-defence efficacy scale. Some participants were exposed to and successful in using verbal and physical resistance strategies in potential sexual assault risky situations. CONCLUSION: These findings indicate the potential beneficial effects of NV! as a campus sexual violence risk reduction intervention at one-year post-intervention, which must be evaluated in a future rigorous randomised control trial.

Symptoms of posttraumatic stress partially mediate the relationship between gender-based violence and alcohol misuse among South African women.

BACKGROUND: The association of traumatic experiences with problematic alcohol use has been described, but data on possible mediation effects of mental distress are sparse. We examined whether mental ill-health mediated the association between trauma exposure across the lifespan and alcohol use. METHOD: We analysed cross-sectional data from a sample of rape-exposed and non-rape-exposed women, living in KwaZulu-Natal, with self-reported data on alcohol misuse (AUDIT-C cut-off ≥ 3) and exposure to childhood maltreatment (CM), intimate partner violence (IPV), non-partner sexual violence (NPSV), other traumatic events, and mental ill-health. Logistic regression and multiple mediation models were used to test the mediation effects of symptoms of depression and PTSS on the association between abuse/trauma and alcohol misuse. RESULTS: Of 1615 women, 31% (n = 498) reported alcohol misuse. Exposure to any CM (adjusted odds ratio (aOR): 1.59, 95% confidence interval (CI): 1.27-1.99), as well as to sexual, physical and emotional CM, were independently associated with alcohol misuse. Lifetime exposure to any IPV (aOR:2.01, 95%CI:1.59-2.54), as well as to physical, emotional and economic IPV, NPSV (aOR: 1.75, 95%CI: 1.32-2.33), and other trauma (aOR:2.08, 95%CI:1.62-2.66), was associated with alcohol misuse. Exposure to an increasing number of abuse types, and other traumatic events, was independently associated with alcohol misuse. PTSS partially mediated the associations of CM, IPV, NPSV and other trauma exposures with alcohol misuse (ps ≤ 0.04 for indirect effects), but depression symptoms did not. CONCLUSIONS: These findings highlight the need for trauma-informed interventions to address alcohol misuse that are tailored to the needs of women who have experienced violence.

Pooled analysis of the association between food insecurity and violence against women: Evidence from low- and middle-income settings.

Background: Intimate partner violence impacts relationships across the socioeconomic spectrum, nonetheless its prevalence is reported to be highest in areas that are most socio-economically deprived. Poverty has direct and indirect impacts on intimate partner violence (IPV) risk, however, one of the postulated pathways is through food insecurity. The aim of this paper is to describe the association between food insecurity (household hunger) and women's experiences, and men's perpetration, of intimate partner violence and non-partner sexual violence in data from Africa and Asia. Methods: We conducted a pooled analysis of data from baseline interviews with men and women participating in six Violence Against Women prevention intervention evaluations and present a meta-analysis using mixed-effects Poisson regression models. Data were from South Africa (two studies), Ghana, Rwanda (two data sets), and Afghanistan and comprised interviews with 6545 adult women and 8104 adult men. We assessed food insecurity with the Household Hunger Scale. Results: Overall, 27.9% of women experienced moderate food insecurity (range from 11.1% to 44.4%), while 28.8% of women reported severe food insecurity (range from 7.1 to 54.7%). Overall food insecurity was associated with an increased likelihood of women experiencing physical intimate partner violence, adjusted incidence rate ratio (aIRR) = 1.40 (95% CI = 1.23 to 1.60) for moderate food insecurity and aIRR = 1.73 (95% CI = 1.41 to 2.12) for severe food insecurity. It was also associated with an increased likelihood of men reporting perpetration of physical IPV, with aIRR = 1.24 (95% CI = 1.11 to 1.39) for moderate food insecurity and aIRR = 1.18 (95% CI = 1.02 to 1.37) for severe food insecurity. Food insecurity was not significantly associated with women's experience of non-partner sexual violence, aIRR = 1.27 (95% CI = 0.93 to 1.74) for moderate or severe food insecurity vs none, nor men's perpetration of non-partner sexual violence aIRR = 1.02 (95% CI = 0.90 to 1.15). Conclusions: Food insecurity is associated with increased physical intimate partner violence perpetration and experience reported by men and women. It was not associated with non-partner sexual violence perpetration, although there was some evidence to suggest an elevated risk of non-partner sexual violence among food-insecure women. Prevention programming needs to embrace food insecurity as a driver of intimate partner violence perpetration, however, non-partner sexual violence prevention needs to be shaped around a separate understanding of its drivers.

Adaptation and pre-test of a shortened Stepping Stones and Creating Futures intervention focused on HIV for young men in rural South Africa.

Men's engagement in HIV prevention and treatment is suboptimal, including in South Africa. We sought to address this through adapting an evidence-based intervention, Stepping Stones and Creating Futures (SSCF), to strengthen its HIV content and provide a more scalable (shorter) intervention in rural South Africa. We then conducted a mixed methods pre-test of the intervention among young men aged 18-35 years. To adapt SSCF, we reviewed the current evidence base and worked with male Peer Navigators to update the SSCF theory of change (ToC) and manual. The revised intervention was ~45 hours (9 sessions) as opposed to ~63 hours and included a greater focus on HIV prevention and treatment technologies. Overall, 64% (n = 60) of men approached agreed to participate in the intervention, uptake (attending one session) among those who agreed was n = 35(58%) and retention (attending 6 or more sessions) was n = 25(71%). Qualitative data emphasized the intervention was acceptable, with young men describing it as something they liked. The qualitative data also broadly supported the intervention ToC, including the normalization of HIV in men's lives, and the importance of health for men in achieving their life goals. However, it also highlighted the need to focus more on HIV-related stigma and fear, and the importance of HIV self-testing kits in encouraging testing. We revised the ToC and manual in light of this data. The adapted SSCF is acceptable and supports the ToC. Next steps is an evaluation to look at effectiveness of the intervention.

Pooled analysis of the association between mental health and violence against women: evidence from five settings in the Global South.

OBJECTIVES: To describe associations between men's poor mental health (depressive and post-traumatic stress symptomatology) and their perpetration of intimate partner violence (IPV) and non-partner sexual violence (NPSV), and women's mental health and their experiences of IPV and NPSV in five settings in the Global South. DESIGN: A pooled analysis of data from baseline interviews with men and women participating in five violence against women and girls prevention intervention evaluations. SETTING: Three sub-Saharan African countries (South Africa, Ghana and Rwanda), and one Middle Eastern country, the occupied Palestinian territories. PARTICIPANTS: 7021 men and 4525 women 18+ years old from a mix of self-selecting and randomly selected household surveys. MAIN OUTCOME MEASURES: All studies measured depression symptomatology using the Centre for Epidemiological Studies-Depression, and the Harvard Trauma Scale for post-traumatic stress disorder (PTSD) symptoms among men and women. IPV and NPSV were measured using items from modified WHO women's health and domestic violence and a UN multicountry study to assess perpetration among men, and experience among women. FINDINGS: Overall men's poor mental health was associated with increased odds of perpetrating physical IPV and NPSV. Specifically, men who had more depressive symptoms had increased odds of reporting IPV (adjusted OR (aOR)=2.13; 95%CI 1.58 to 2.87) and NPSV (aOR=1.62; 95% CI 0.97 to 2.71) perpetration compared with those with fewer symptoms. Men reporting PTSD had higher odds of reporting IPV (aOR=1.87; 95% CI 1.44 to 2.43) and NPSV (aOR=2.13; 95% CI 1.49 to 3.05) perpetration compared with those without PTSD. Women who had experienced IPV (aOR=2.53; 95% CI 2.18 to 2.94) and NPSV (aOR=2.65; 95% CI 2.02 to 3.46) had increased odds of experiencing depressive symptoms compared with those who had not. CONCLUSIONS: Interventions aimed at preventing IPV and NPSV perpetration and experience must account for the mental health of men as a risk factor, and women's experience.

A Prospective Analysis of the Interrelationship between Physical Intimate Partner Violence and Alcohol Use: A Post-Hoc Analysis of Young Women Involved in the Stepping Stones and Creating Futures Trial in South Africa.

Prospective studies assessing women's experience of intimate partner violence (IPV) and alcohol use have shown mixed results and all are from high-income countries. Using longitudinal data from young women in South Africa we assess whether changes in physical IPV impact alcohol use, and whether changes in alcohol use impact physical IPV experience. Post-hoc analysis of women aged 18-30 living in informal settlements in eThekwini Municipality, South Africa, involved in the Stepping Stones and Creating Futures trial, between September 2015 and October 2019, with data collected at baseline (n = 677) and endline at 24 months (n = 545, 80.5% retention). At both timepoints, women were asked about their past year physical IPV experience and alcohol use. We estimated changes in physical IPV over time and whether this was associated with harmful alcohol use at endline. We then estimated changes in alcohol use over time, and whether this was associated with experience of past year physical IPV at endline. Women who experienced an increase in physical IPV over the study period were more likely to report harmful drinking at 24 months (aOR2.45, 95% CI 1.21-4.97). Similarly, women reporting increased alcohol use over time were more likely to report past year physical IPV at 24 months (aOR2.04, 95% CI 1.21-3.46). Among young women living in urban poverty those who experienced increasing physical violence from intimate partners were more likely to report increased and problematic alcohol use. Similarly, women reporting increasing alcohol use over 24 months were more likely to report physical IPV. However, there was no evidence that decreased alcohol use led to reductions in IPV, or that reduced IPV experience led to decreased alcohol use. Future research and interventions need to consider the reciprocal risks of physical IPV and alcohol use, with a focus on joint underlying drivers.

Household Food Insecurity and Demographic Factors, Low Birth Weight and Stunting in Early Childhood: Findings from a Longitudinal Study in South Africa.

BACKGROUND: Low birthweight (LBW) as well as early childhood stunting are risk factors for increased childhood morbidity in low-and middle-income countries (LMIC). The Covid 19 pandemic has exacerbated food insecurity and unemployment globally, prompting concerns for maternal and child health. OBJECTIVES: We used data from the great recession of 2008 to examine the relationship between household food security and other risk factors with LBW and stunting using a longitudinal sample of South African women and their offspring. METHODS: Food security indicators, alcohol use, blood pressure and other characteristics were examined in relation to LBW (≤ 2500 g), stunting (height for age ≤ 2SD) and severe stunting (height for age ≤ 3SD). Regression modelling with clustering at maternal ID level were employed to adjust for maternal characteristics and women who gave birth more than once during the reference period. RESULTS: Birthweight data were available for 1173 children and height for age 1216 children. The prevalence of LBW was 14.7% while stunting and severe stunting was 17.8% and 14.5%. Child hunger in the household, maternal hypertension and alcohol use were associated with low birthweight. Food expenditure below the Stats SA poverty line and low dietary diversity was associated with stunting and severe stunting respectively. Maternal height and low birthweight were associated with both stunting and severe stunting. CONCLUSIONS FOR PRACTICE: Interventions that can improve household food security and nutritional status during the periconceptional and antenatal period may reduce the prevalence of low birthweight and subsequent stunting in low- and middle-income countries.

Prospective Association of Circulating Adipokines with Cardiometabolic Risk Profile Among Women: The Rape Impact Cohort Evaluation Study.

Background: Sexual violence is associated with poor cardiometabolic outcomes, yet the etiopathogenic pathways remain unclear. Adipokines may contribute to pathways in the development of cardiometabolic disease (CMD), including in vulnerable populations. Further investigation of adipokines among sexually traumatized individuals may inform cardiometabolic screening. This study aimed to investigate the association between circulating adipokines, metabolic syndrome (MetS), and longitudinal change in MetS components (namely abdominal obesity, blood pressure, lipid profile, and glycemic status) over a 1-year period in a cohort of rape exposed (RE) and rape unexposed (RUE) females. Materials and Methods: Seven hundred seventy-eight RE and 617 RUE black South African women aged 18-40 years were recruited for the Rape Impact Cohort Evaluation study. Nonfasting blood samples were analyzed for cardiometabolic variables and adipokine levels using enzyme-linked immunosorbent assay. Serum adiponectin was measured in both RE and RUE and resistin, leptin, and leptin/adiponectin (L/A) ratio in RE only. Associations between baseline serum adipokines, MetS, and its components were assessed at baseline and follow-up using adjusted linear and logistic regressions. Results: In the RE group, adiponectin, leptin, and L/A ratio were significantly associated with MetS prevalence cross-sectionally (all p ≤ 0.001). No adipokine marker was related to incident MetS at 12-month follow-up. In the RE group, significant longitudinal associations with high-density lipoprotein cholesterol were shown for adiponectin (ß = 0.146 [0.064], p = 0.022) and leptin (ß = 0.001 [0.002], p = 0.012). Conclusions: Findings suggest that adipokines may have a potential role as biomarkers to identify RE individuals at high risk for CMD.

Quantitative evaluation of Zindagii Shoista (Living with Dignity) intervention to prevent violence against women in Tajikistan.

BACKGROUND: Violence against women and girls (VAWG) is a major problem in Tajikistan, driven by conservative gender norms, the culturally ascribed position of young women, and poverty. OBJECTIVE: We evaluated Zindagii Shoista (Living with Dignity), an intervention developed with the aim of reducing VAWG through a combination of gender norm change, communication skills, and income-generating activities (IGA) over a period of 30 months. METHODS: The evaluation used a mixed-methods approach, combining quantitative and qualitative data collection. Eighty families from four villages were enrolled in the intervention and surveyed at baseline and on three subsequent occasions. From these families, 134 women and 102 men were interviewed at baseline, 153 women and 89 men 8 months later, 153 women and 93 men 15 months later, and 143 women and 82 men, 30 months after the baseline. Generalised random effects regression models were used to assess the trend in proportions or mean score over time. RESULTS: Over the 30 months, the proportion of women and men earning in the past month rose from 17.9% to 56.6% and 44.1% to 72%, respectively. Women and men's gender attitudes became significantly less patriarchal, and they reported less harmful gender norms in the community. Women and men reported less male controlling behaviour and greater woman involvement in decision-making. Women's reports of experience of emotional, physical, and sexual IPV significantly reduced. Depressive symptoms and suicidal thoughts reduced significantly for men and women, and self-rated health improved. CONCLUSIONS: The quantitative findings are confirmed by the findings of the qualitative research and monitoring data. They demonstrate that Zindagii Shoista is a very promising intervention for strengthening gender relations, reducing IPV, and improving mental health and socio-economic circumstances for younger married women and their families in Tajikistan.

Dietary diversity, food insecurity and the double burden of malnutrition among children, adolescents and adults in South Africa: Findings from a national survey.

Childhood stunting remains a global public health problem. Many stunted children live in the same household as overweight or obese adults (the so-called double burden of malnutrition), evidence that quality as well as quantity of food is important. In recent years, food security measurement has shifted away from anthropometry (e.g., stunting) to experiential measures (e.g., self-reported hunger). However, given the continued problem of stunting, it is important that national surveys identify malnutrition. Objectives: To examine the associations between a variety of food security indicators, including dietary diversity, with adult, child (0-4 years) (5-9 years) and adolescent (10-17 years) anthropometry. To estimate the prevalence of double burden households. Methods: The study utilized cross-sectional data from the South African National Income Dynamics Survey NIDS (2008). We examined the associations between five food security indicators and anthropometry outcomes. The indicators were adult and child hunger in the household, self-reported household food sufficiency, food expenditure>60% of monthly expenditure and household dietary diversity. Multinomial and logistic regression models were employed to examine the associations with adult BMI categories and children's stunting and BMI. Results: The prevalence of stunting was 18.4% and the prevalence of wasting and overweight was 6.8 and 10.4%, respectively. Children <5 and adolescents with medium dietary diversity were significantly more likely to be stunted than children with high dietary diversity. Among children <5, child hunger and medium dietary diversity were significantly associated with wasting. None of the food security indicators were associated with stunting in children aged 5-9. Among stunted children, 70.2% lived with an overweight or obese adult. Among adults, increased dietary diversity increased the risk of overweight and obesity. Conclusion: Dietary diversity can be used as a proxy for poor nutritional status among children <5 years and adolescents but the relationship between dietary diversity and adult obesity is more complex. Given the double burden of malnutrition in many low- and middle-income countries, indicators of dietary quality remain important. These tools can be further refined to include an extra category for processed foods. Given the relative simplicity to collect this data, national surveys would be improved by its inclusion.

Serum adiponectin-levels are predictive of probable posttraumatic stress disorder in women.

Background: Accumulative evidence indicates a role for adiponectin, a polypeptide secreted by adipose tissue, in the pathophysiology of posttraumatic disorder (PTSD) via metabolic and inflammatory pathways. This study examined adiponectin as a potential predictive biomarker for PTSD among female rape survivors. Methods: We evaluated the relationship of baseline serum adiponectin levels to the development of probable PTSD at 3- and 6-months post rape-exposure and compared adiponectin levels between 542 rape-exposed (RE) and 593 rape-unexposed women (RUE). Probable PTSD were defined as Davidson Trauma Scale score ≥40. Data were analysed using multivariate regression models and a generalized estimating equation (GEE) model. We adjusted for clinically relevant covariates associated with PTSD, as well as adiposity indices. Results: Participants who were in the mid-and high adiponectin tertile groups versus the lowest tertile group had a significantly reduced risk of probable PTSD among at 6 months follow-up, independent of adiposity(aOR = 0.45[0.22-1.05], p = 0.035; aOR = 0.44[0.22-0.90], p = 0.024). However, there was no effect of group (RE vs. RUE). Limitations: Adiponectin assays were conducted on non-fasting blood samples and information on chronic medication, dietary factors and levels of physical activity were not collected. There was a high attrition rate among rape exposed participants. Conclusions: Our results show that higher serum adiponectin levels are associated with reduced risk of probable PTSD over a 6-month period. This finding supports the hypothesis that serum adiponectin is a potential risk biomarker for PTSD.

Adiponectin gene polymorphisms and posttraumatic stress disorder symptoms among female rape survivors: an exploratory study.

Background: Rape is a common traumatic event which may result in the development of posttraumatic stress disorder (PTSD), yet few studies have investigated risk biomarkers in sexually traumatised individuals. Adiponectin is a novel cytokine within inflammatory and cardiometabolic pathways with evidence of involvement in PTSD. Objective: This prospective exploratory study in a sample of female rape survivors investigated the association of single nucleotide polymorphisms (SNPs) in the adiponectin gene (ADIPOQ) and posttraumatic stress symptom (PTSS) severity, and the interaction of these SNPs of interest with childhood trauma in modifying the association with PTSS severity. Method: The study involved 455 rape-exposed black South African women (mean age (SD), 25.3 years (±5.5)) recruited within 20 days of being raped. PTSS was assessed using the Davidson Trauma Scale (DTS) and childhood trauma was assessed using a modified version of the Childhood Trauma Scale-Short Form Questionnaire. Eight ADIPOQ SNPs (rs17300539, rs16861194, rs16861205, rs2241766, rs6444174, rs822395, rs1501299, rs1403697) were genotyped using KASP. Mixed linear regression models were used to test additive associations of ADIPOQ SNPs and PTSS severity at baseline, 3 and 6 months following rape. Results: The mean DTS score post-sexual assault was high (71.3 ± 31.5), with a decrease in PTSS severity shown over time for all genotypes. rs6444174TT genotype was inversely associated with baseline PTSS in the unadjusted model (ß = -13.6, 95% CI [-25.1; -2.1], p = .021). However, no genotype was shown to be significantly associated with change in PTSS severity over time and therefore ADIPOQ SNP x childhood trauma interaction was not further investigated. Conclusion: None of the ADIPOQ SNPs selected for investigation in this population were shown to be associated with change in PTSS severity over a 6-month period and therefore their clinical utility as risk biomarkers for rape-related PTSD appears limited. These SNPs should be further investigated in possible gene-gene and gene-environment interactions.

Antecedentes: La violación sexual es un evento traumático común que puede resultar en el desarrollo del trastorno de estrés postraumático (TEPT); no obstante, pocos estudios han investigado biomarcadores de riesgo en personas sexualmente traumatizadas. La adiponectina es una citocina recientemente involucrada en vías inflamatorias y cardiometabólicas que tienen evidencia de compromiso en el TEPT.Objetivo: Este estudio prospectivo exploratorio, realizado en una muestra de mujeres sobrevivientes a violación sexual, investigó la asociación entre polimorfismos de nucleótido único (SNPs por sus siglas en inglés) en el gen de la adiponectina (ADIPOQ) y la severidad de los síntomas de estrés postraumático (SEPT), así como también cómo la interacción de estos SNPs sobre el trauma infantil modifica la asociación con la severidad de los SEPT.Método: El estudio incluyó a 455 mujeres sudafricanas de raza negra expuestas a una violación sexual (edad promedio de 25,3 años ± 5,5) reclutadas 20 días después de haber sido violadas sexualmente. Los SEPT se evaluaron empleando la Escala de Trauma de Davidson (DTS por sus siglas en inglés) y el trauma infantil se evaluó empleando una versión modificada de la Escala de Trauma Infantil ­ Cuestionario de versión corta. Se realizó la genotipificación de ocho SNPs del gen ADIPOQ (rs17300539, rs16861194, rs16861205, rs2241766, rs6444174, rs822395, rs1501299, rs1403697) empleando el KASP. Se emplearon modelos de regresión lineal para evaluar las asociaciones aditivas entre los SNPs del gen ADIPOQ y la severidad de los SEPT de base, a los tres y a los seis meses luego de la violación sexual.Resultados: El promedio del puntaje en la DTS luego de una violación sexual fue alto (71,3 ± 31,5) con una disminución en la severidad de los SEPT evidenciada a lo largo del tiempo para todos los genotipos. El genotipo rs6444174TT se encontró inversamente asociado a los SEPT de base en el modelo no ajustado (ß = −13.6, 95% CI [−25.1; −2.1], p = .021). Sin embargo, ningún genotipo mostró estar asociado significativamente con cambios en la severidad de los SEPT a lo largo del tiempo y, por tanto, ya no se investigó la interacción entre los SNPs del gen ADIPOQ y el trauma infantil.Conclusiones: Ninguno de los SNPs del ADIPOQ elegidos para esta investigación mostraron tener alguna asociación entre los cambios en la severidad de los SEPT en un periodo de seis meses y, por tanto, su utilidad clínica como marcadores de riesgo para el TEPT asociado a violación sexual es limitada. Se debería investigar más estos SNPs para evaluar las posibles interacciones gen-gen y gen-ambiente.

Suicidal Thoughts, Depression, Post-Traumatic Stress, and Harmful Alcohol Use Associated with Intimate Partner Violence and Rape Exposures among Female Students in South Africa.

While ample evidence from high-income country settings indicates the prevalence and risk factors for multiple mental ill-health symptoms in student populations, evidence from low- and middle-income higher education settings remains limited. We determined the frequency, associations, and structural pathways between mental health outcomes and possible risk factors among a sample of 1292 predominantly Black African and female students ages 18-30 years, enrolled at nine purposefully selected public universities and Technical Vocational Education and Training (TVET) campuses. We measured and created a mental ill-health latent outcome consisting of depressive symptoms, post-traumatic stress disorder (PTSD), and suicidal thoughts. We also measured traumatic exposures including childhood trauma, recent intimate partner violence (IPV), non-partner rape, and other life traumatic events. We used structural equation modelling to analyse data. We found that 50% of the surveyed students binge drank, 43% reported depressive symptoms, 9% reported PTSD symptoms, and 21% had suicidal thoughts. Students' experiences of childhood trauma, food insecurity, other traumatic events, non-partner rape, and IPV impacted the mental ill-health latent. IPV experiences mediated the relationships between experiences of childhood trauma or other trauma and the mental ill-health latent, and the relationship between binge drinking and other life traumatic events. Non-partner rape mediated the relationship between food insecurity and the mental ill-health latent. Binge drinking directly impacted non-partner rape experience. The findings substantiate the need for campus-based mental health promotion, psychosocial services and treatments, and implementation of combined interventions that address the intersections of violence against women and mental health among students in South Africa.

Does experiencing a traumatic life event increase the risk of intimate partner violence for young women? A cross-sectional analysis and structural equation model of data from the Stepping Stones and Creating Futures intervention in South Africa.

OBJECTIVES: To investigate associations and potential pathways between women's lifetime exposure to traumatic events and their recent experiences of intimate partner violence (IPV). SETTING: South African informal settlements near Durban. PARTICIPANTS: 677 women, living in informal settlements, aged 18-30 years, currently out of school or formal employment. PRIMARY AND SECONDARY OUTCOME MEASURES: Self-reported experiences of IPV in the past 12 months and exposure to traumatic neighbourhood events (including witnessing murder, being robbed or kidnapped, witnessing and experiencing rape). RESULTS: Exposure to traumatic events was common among the 677 women surveyed. Over 70% had experienced at least one in their lifetime; one quarter (24%) had experienced 3 or more different events. Women exposed to any traumatic event had a 43% increase in the odds of experiencing IPV in comparison to those with no exposure (aOR 1.43, p≤0.000). Exposure to non-partner rape is more strongly associated with IPV than any other traumatic experience. Pathways from exposure to traumatic events and non-partner rape to recent IPV experience are mediated by a latent variable of poor mental health. Food insecurity is associated with all forms of traumatic experience, and is also indirectly associated with IPV through views by women that are unsupportive of gender equality. CONCLUSIONS: Women living in South African informal settlements who witness or experience traumatic events were likely to experience IPV, and this increases when women were exposed to multiple types of events. Our model suggests that experiencing traumatic events, and non-partner rape in particular, has negative effects on women's mental health in ways that may increase their vulnerability to IPV. IPV prevention interventions should consider the broader impacts of women's exposure to neighbourhood violence and severe poverty on IPV risk in settings where these are endemic.

The Associations of Intimate Partner Violence and Non-Partner Sexual Violence with Hypertension in South African Women.

This study describes associations of intimate partner violence (IPV), non-partner sexual violence (NPSV) and sexual harassment (SH) exposures with hypertension in South African women aged 18-40 years. Baseline data (n = 1742) from the Rape Impact Cohort Evaluation study, including a history of sexual, physical, emotional and economic IPV, NPSV and SH were examined. Hypertension was based on blood pressure ≥140/90 mmHg or a previous diagnosis. Logistic regressions were adjusted for traditional hypertension risk factors and previous trauma (e.g., recent rape). Hypertension was more prevalent in women with a history of all forms of IPV, NPSV, and SH, all p ≤ 0.001, compared to women without. Frequent NPSV (adjusted odds ratio: 1.63; 95% CI: 1.27-2.67) any SH (2.56; 1.60-4.03), frequent physical (1.44; 1.06-1.95) and emotional IPV (1.45; 1.06-1.98), and greater severity of emotional IPV (1.05; 1.02-1.08) were associated with hypertension. Current depression, post-traumatic stress symptoms and/or alcohol binge-drinking completely or partially mediated these associations. This study shows that exposure to gender-based violence is associated with hypertension in young women. Understanding the role of psychological stress arising from abuse may enable the development of prevention and management strategies for hypertension among women with histories of abuse.

Prevention of violence against women and girls: A cost-effectiveness study across 6 low- and middle-income countries.

BACKGROUND: Violence against women and girls (VAWG) is a human rights violation with social, economic, and health consequences for survivors, perpetrators, and society. Robust evidence on economic, social, and health impact, plus the cost of delivery of VAWG prevention, is critical to making the case for investment, particularly in low- and middle-income countries (LMICs) where health sector resources are highly constrained. We report on the costs and health impact of VAWG prevention in 6 countries. METHODS AND FINDINGS: We conducted a trial-based cost-effectiveness analysis of VAWG prevention interventions using primary data from 5 randomised controlled trials (RCTs) in sub-Saharan Africa and 1 in South Asia. We evaluated 2 school-based interventions aimed at adolescents (11 to 14 years old) and 2 workshop-based (small group or one to one) interventions, 1 community-based intervention, and 1 combined small group and community-based programme all aimed at adult men and women (18+ years old). All interventions were delivered between 2015 and 2018 and were compared to a do-nothing scenario, except for one of the school-based interventions (government-mandated programme) and for the combined intervention (access to financial services in small groups). We computed the health burden from VAWG with disability-adjusted life year (DALY). We estimated per capita DALYs averted using statistical models that reflect each trial's design and any baseline imbalances. We report cost-effectiveness as cost per DALY averted and characterise uncertainty in the estimates with probabilistic sensitivity analysis (PSA) and cost-effectiveness acceptability curves (CEACs), which show the probability of cost-effectiveness at different thresholds. We report a subgroup analysis of the small group component of the combined intervention and no other subgroup analysis. We also report an impact inventory to illustrate interventions' socioeconomic impact beyond health. We use a 3% discount rate for investment costs and a 1-year time horizon, assuming no effects post the intervention period. From a health sector perspective, the cost per DALY averted varies between US$222 (2018), for an established gender attitudes and harmful social norms change community-based intervention in Ghana, to US$17,548 (2018) for a livelihoods intervention in South Africa. Taking a societal perspective and including wider economic impact improves the cost-effectiveness of some interventions but reduces others. For example, interventions with positive economic impacts, often those with explicit economic goals, offset implementation costs and achieve more favourable cost-effectiveness ratios. Results are robust to sensitivity analyses. Our DALYs include a subset of the health consequences of VAWG exposure; we assume no mortality impact from any of the health consequences included in the DALYs calculations. In both cases, we may be underestimating overall health impact. We also do not report on participants' health costs. CONCLUSIONS: We demonstrate that investment in established community-based VAWG prevention interventions can improve population health in LMICs, even within highly constrained health budgets. However, several VAWG prevention interventions require further modification to achieve affordability and cost-effectiveness at scale. Broadening the range of social, health, and economic outcomes captured in future cost-effectiveness assessments remains critical to justifying the investment urgently required to prevent VAWG globally.

Pathways to and factors associated with rape stigma experienced by rape survivors in South Africa: Analysis of baseline data from a rape cohort.

Rape stigma, both external and self-stigmatization (self-blame), is associated with adverse health outcomes. Understanding its origins and resilience factors is critical for reducing and preventing it. We describe the prevalence of rape stigma, the characteristics of women experiencing it and the pathways to experiencing greater stigma. The Rape Impact Cohort Evaluation study enrolled 852 women aged 16-40 years who had been raped from post-rape care centres in Durban, South Africa. We present a descriptive analysis of the baseline data, a multinomial logistic regression model of factors associated with different levels of stigma and a structural equation model (SEM). Most women reported stigmatizing thoughts or experiences, with self-stigmatizing thoughts being more prevalent than external stigmatization. The multinomial model showed that experiences of childhood or other trauma, emotional intimate partner violence (IPV), having less gender equitable attitudes and food insecurity were significantly associated with medium or high versus low levels of stigma. Internal and external stigma were significantly associated with each other. Women who had been previously raped reported less stigma. The SEM showed a direct path between food insecurity and rape stigma, with poorer women experiencing more stigma. Indirect paths were mediated by more traditional gender attitudes and childhood trauma experience and other trauma exposure. Our findings confirm the intersectionality of rape stigma, with its structural drivers of food insecurity and gender inequality, as well as its strong association with prior trauma exposure. Rape survivors may benefit from gender-empowering psychological support that addresses blame and shame.

Factors associated with female students' past year experience of sexual violence in South African public higher education settings: A cross-sectional study.

BACKGROUND: Intimate partner sexual violence and non-partner rape experiences are widely reported by female students in South African higher education institutions, as they are globally. However, limited research has focused on investigating vulnerability factors, which is vital for informing interventions. OBJECTIVE: To describe the factors and inter-relationships associated with female students' increased vulnerability to past year experience of partner sexual violence and non-partner rape in South African higher education settings. METHODS: We interviewed 1293 female students, i.e., 519 students in six Technical Vocational Education and Training (TVET) college campuses and 774 students at three university campuses. Participants were volunteers aged 18-30. The measured vulnerability factors included childhood sexual abuse, other trauma, mental ill-health, risky sexual behaviours, food insecurity, partner violence, and controlling behaviours. We used bivariate analysis, logistic regression, and structural equation modelling methods. RESULTS: Twenty percent of participants experienced past-year sexual violence (17% partner sexual violence and 7.5% non-partner rape). Childhood sexual abuse had direct effects on experiencing past year sexual violence and physical, emotional partner violence or controlling behaviours. Risky sexual behaviours mediated the relationships of childhood sexual abuse or harmful alcohol use and past-year sexual violence experience. Mental ill-health mediated the relationships between childhood sexual abuse, other traumatic exposures, food insecurity, physical, emotional partner violence or controlling behaviours, and past-year partner sexual violence or non-partner rape experience. CONCLUSIONS: Risky sexual behaviours, gender inequitable relationship dynamics, mental ill-health, and food insecurity are related and amenable vulnerability factors associated with female students' sexual violence experiences. Therefore, addressing these through comprehensive campus interventions, which are implemented when students first enrol in higher education and are most vulnerable to sexual violence, is critical. Society-wide sexual violence prevention is also imperative.
