    Exposure To Family Violence and Low Parental Connectedness Associated with Depressive Symptoms, Substance Use and Violence Outcomes Among Adolescents In South Africa

    by Mercilene Tanyaradzwa Machisa, Rachel Jewkes, Simukai Shamu, Pinky Mahlangu, Esnat Chirwa

    Purpose: Limited research has explored the impacts of family violence on early adolescent mental health and behaviour, in low- and middle-income countries. We examined the associations between family violence, adolescent mental health, and violent behaviours to identify potential pathways for disrupting the intergenerational cycle of violence, thereby addressing key evidence gaps in this area. Methods: Data was collected among 3756 learners, ages 11–16 years, participating in a cluster-randomized trial in South Africa. Descriptive statistics, bivariate regressions, and separate structural equation models explored pathways linking family violence to depressive symptoms (girls) and dating violence perpetration (boys). Results: We found gender disparities in family violence experiences and adolescent outcomes. Boys reported higher exposure to family violence, lower caregiver support, and more problematic behaviours than girls. While girls and boys showed similar depression rates, pathways differed. For girls, exposure to family violence, directly and indirectly, predicted depression through reduced parent–child connection, delinquency, negative school attitudes, and bullying. Boys' exposure to family violence predicted dating violence indirectly through depression, substance use, and delinquency, with depression also directly impacting substance use. Conclusions: Exposure to family violence and poor parent–child relationships significantly contributed to the onset of poor mental health, negative attitudes toward school, behavioral problems, and violence in early adolescence, potentially perpetuating intergenerational cycles of violence. These findings highlight the urgent need for multifaceted, evidence-based interventions designed to disrupt these cycles and improve early adolescent mental health and academic outcomes. Rigorous development and evaluation of such interventions are crucial, especially within the South African context.

    Refusal of male partner responsibility and pregnancy support: prevalence, associated factors and health outcomes in a cross sectional study in Harare, Zimbabwe

    by Simukai Shamu, Patience Shamu, Mercilene Tanyaradzwa Machisa

    The phenomenon of fathers refusing responsibility during pregnancy has not received adequate attention in African studies. This paper assesses associated factors and pregnancy-related outcomes when fathers refuse to support partners’ pregnancies and undertake parental responsibilities. A cross-sectional survey of 15–49-year-old postnatal (1–6 weeks) women was conducted at six urban health facilities in Harare. Participants were interviewed about their male partners’ refusal to support their pregnancies and parenting, bride price payments (indicating marriage commitment), partner violence and control, alcohol abuse and family planning decision-making. Pregnancy health outcome data including antenatal care attendance, low birth weight (LBW)(< 2500 g) and postnatal depression were collected through interviews and clinic records. Multiple regression models were built to assess gender-related factors and health outcomes associated with male partners’ refusal of parenting responsibilities. Of the 2042 women interviewed, 6.4% reported partner refusal to support the pregnancy or parenting. Higher odds of partner refusal of fathering responsibility were associated with partners not paying bride price (aOR 9.31; 95% CI 1.16–74.59), violence perpetration during pregnancy (aOR 2.84; 1.28–6.23), highly controlling behaviours (aOR 4.96; 2.83–8.69), alcohol abuse (aOR 1.78; 1.05–3.02), unintended pregnancy (aOR 3.72; 1.84–7.53) and partner refusal to use contraceptives (aOR 3.64; 1.86–7.14). Women who used contraceptives (aOR 0.40; 0.23–0.71), made joint (aOR 0.30; 0.14–0.67) or individual (aOR 0.25; 0.07–0.94) pregnancy decisions were protected from partner refusal of parenting responsibility. Women’s depressive symptomatology (aOR2.64; 1.52–4.59), LBW (aOR5.30; 1.18–23.74) and partner discouragement of antenatal care attendance (aOR 3.86; 1.13–13.17) were pregnancy outcomes associated with partner refusal of parenting responsibility. Male partners’ refusal to acknowledge parenting responsibility was associated with men’s abusiveness, absence of commitment to long-term relationship/marriage, gender unequal practices and negative maternal and child health outcomes. Parenting programmes must be instituted and prioritise transforming traditional gender norms to improve fathering responsibilities.

    COVID-19 and Female Genital Mutilation/Cutting and child marriage: An online multi-country cross sectional survey

    by Shania Pande, Simukai Shamu, Amr Abdelhamed, James Munyao Kingoo, Sarah Van de Velde, Marleen Temmerman, Tammary Esho, Samuel Kimani, Joyce Omwoha, Eneyi E Kpokiri, et al.

    Female Genital Mutilation/Cutting (FGM/C) and child marriage are prevalent in many countries in Asia and Africa. These practices are a violation of human rights and have significant impacts on the physical and mental well-being of those affected. COVID-19 restrictions such as lockdowns and closure of schools may have influenced the occurrence of FGM/C and child marriage. This analysis reported on the impact of these restrictions on FGM/C and child marriage. The International Sexual Health And REproductive Health (I-SHARE) research team organised a multi-country online survey. Sampling methods included convenience samples, online panels, and population-representative samples. Data collected included the impact of COVID-19 restrictions on the occurrence, intention to practice and change in plans to organise FGM/C and child marriage. Data were analysed from 14 countries that reported on FGM/C and child marriage using basic descriptive statistics. Given it was an online survey, we had more responses from urban areas. Among the 22,724 overall participants, 8,829 participants (38.9%) responded to the survey items on FGM/C and child marriage and were included in this analysis. 249 (3.4%) participants stated that FGM/C occurred in their community during COVID-19. Out of this, COVID-19 affected the plans of 26 (20%) participants intending to organise circumcision and 15% of participants planned to organise FGM/C earlier. People with a worry about finances during COVID-19 were more likely to have an earlier plan to organise FGM/C during COVID-19. In total, 1,429 (13%) participants reported that child marriage occurred in their community. The pandemic affected plans of 52 (13%) participants intending to arrange child marriage and 7.7% (29/384) participants expressed intent to arrange the marriage sooner than planned. People with financial insecurities during COVID-19 were more likely to arrange a child marriage earlier. Thus, our study found that the pandemic impacted plans related to FGM/C and child marriage practices, resulting in many carrying out the practices sooner or later than initially planned.

    Associations between depressive symptoms, socio-economic factors, traumatic exposure and recent intimate partner violence experiences among women in Zimbabwe: a cross-sectional study

    by Mercilene Machisa, Simukai Shamu

    Background: Population-based research on the cumulative effects of socio-economic conditions and trauma exposures, particularly women’s experiences of intimate partner violence (IPV) on their mental health in Zimbabwe, has been limited. Aim: Our study aimed to determine the associations between depressive symptoms and socio-economic factors, IPV, and traumatic exposures among a nationally representative sample of women from Zimbabwe. Methods: Data was collected from 2905 women who volunteered to participate in a survey that had a multi-stage random sampling design. Depression was measured using the Centre for Epidemiologic Studies Depression Scale (CESD). Traumatic exposures included childhood trauma, life events, and experiences of IPV in the past year. We compared mean depression scores for different categories of variables, conducted linear regression modelling to investigate the bivariate and multivariate associations between variables and depressive symptoms’ outcomes, and applied Structural Equation Modelling (SEM) to investigate the inter-relationships between variables and depressive symptoms’ outcomes. Results: Fifteen percent of women self-reported depressive symptoms (CESD score ≥ 21). Higher depressive symptomatology was associated with lower socio-economic status, experiencing IPV, history of childhood and other traumatic events, experiencing non-partner rape, and HIV positive status. Women who could find money in an emergency and sought informal or professional emotional support were less at risk of severe depressive symptoms. Conversely, seeking informal and formal social support was positively associated with more severe depressive symptoms. Conclusion: This study contributes evidence showing that economic hardship, exposure to traumas including IPV, living with HIV, and low social support have a cumulative negative toll on mental health among Zimbabwean women from the general population. Programmes and services that respond to the mental ill-health effects reported by Zimbabwean women and prevention interventions that tackle the multiple risk factors for depression that we have identified must be prioritised.

    The International Sexual Health And Reproductive Health Survey (I-SHARE-1): A Multi-Country Analysis of Adults from 30 Countries Prior to and During the Initial COVID-19 Wave

    by Jennifer Toller Erausquin, Rayner K. J. Tan, Maximiliane Uhlich, Joel M. Francis, Navin Kumar, Linda Campbell, Wei-Hong Zhang, Takhona G. Hlatshwako, Priya Kosana, Sonam Shah, et al.

    Background The COVID-19 pandemic forced billions of people to shelter in place, altering social and sexual relationships worldwide. In many settings, COVID-19 threatened already precarious health services. However, there is limited evidence to date about changes to sexual and reproductive health (SRH) during the initial wave of COVID-19 disease. To address this gap, our team organized a multi-country, cross-sectional online survey as part of a global consortium. Methods Consortium research teams conducted online surveys in 30 countries. Sampling methods included convenience, online panels, and population-representative. Primary outcomes included sexual behaviors, partner violence, and SRH service utilization, and we compared three months prior to and three months after policy measures to mitigate COVID-19. We used established indicators and analyses pre-specified in our protocol. We conducted meta-analyses for primary outcomes and graded the certainty of the evidence using Cochrane methods. Descriptive analyses included 22,724 individuals in 25 countries. Five additional countries with sample sizes Results Respondents were mean age 34 years; most identified as women (15160; 66.7%), cis-gender (19432; 86.6%) and heterosexual (16592; 77.9%). Among 4546 respondents with casual partners, condom use stayed the same for 3374 (74.4%) people and 640 (14.1%) people reported a decline. Fewer respondents reported physical or sexual partner violence during COVID-19 measures (1063/15144, 7.0%) compared to the period before COVID-19 measures (1469/15887, 9.3%). COVID-19 measures impeded access to condoms (933/10790, 8.7%), contraceptives (610/8175, 7.5%), and HIV/STI testing (750/1965, 30.7%). Pooled estimates from meta-analysis indicate during COVID-19 measures, 32.3% (95% CI 23.9-42.1) of people needing HIV/STI testing had hindered access, 4.4% (95% CI 3.4-5.4) experienced partner violence, and 5.8% (95% CI 5.4-8.2) decreased casual partner condom use (moderate certainty of evidence for each outcome). Meta-analysis findings were robust in sensitivity analyses that examined country income level, sample size, and sampling strategy. Conclusion Open science methods are feasible to organize research studies as part of emergency responses. The initial COVID-19 wave impacted SRH behaviors and access to services across diverse global settings.

    O18.5 Comparison of Intimate Partner Violence prior to and during the COVID-19 pandemic: Findings from the I-SHARE cross-sectional multi-country study

    by L Campbell, J Tucker, A Gabster, S Shamu, K Mark, A Olumide, S Eleuteri, R Tan, H Saltis, E Kemigisha, et al.

    Background Shelter-in-place and related COVID-19 physical distancing measures may influence the risk of intimate partner violence (IPV). The current study aims to (1) describe perceived changes in IPV experienced during and prior to the COVID-19 outbreak, (2) identify social correlates of IPV. Methods The International Sexual Health and REproductive Health (I-SHARE) study collected data on sexual and reproductive health during the COVID-19 pandemic (10,717 respondents in 16 countries between July 26thand December 1st 2020). The sample comprises participants in 7 HICs, 5 UMICs, 2 LMICs, and 2 LICs: 6,643 (62.3%) participants identified as women, 3,650 (34.2%) as men, and 178 (1.7%) as another gender. The median age was 30 (IQR 24; 39). Adults (≥18yrs) were recruited online (social media, panel, or population-representative). IPV was a primary outcome measured using an adapted six-item version of the WHO IPV scale. Mixed effects modelling was used to assess participants’ experience of IPV in the three months prior to, and during, the COVID-19 physical distancing measures; participants were also asked about informal and formal reporting of IPV. Results Preliminary analysis indicated that 1,864 (17.4%) of the 10,717 participants reported experiencing at least one form of IPV before the introduction of COVID-19 control measures; 1,346 (12.6%) participants reported IPV during COVID-19 physical distancing measures. Among participants experiencing IPV when physical distancing measures were in place, 691 (37.1%) told either a friend, the police, social services or other organization. Participants with a reduction in household income during the COVID-19 measures (aOR 1.48, 95% CI 1.29–1.69) and increased consumption of alcohol during COVID-19 (aOR 1.51, 95% CI 1.26–1.81) had higher odds of experiencing IPV. Conclusion IPV may have decreased during COVID-19 measures, but remained common overall. Structural interventions are necessary to mitigate the impact of IPV.

    Pre-exposure prophylaxis (PrEP) awareness, attitudes and uptake willingness among young people: gender differences and associated factors in two South African districts

    by Simukai Shamu, Patience Shamu, Sikhulile Khupakonke, Thato Farirai, Thato Chidarikire, Geoffrey Guloba, Nkhensani Nkhwashu

    Background: Pre-exposure prophylaxis (PrEP) for HIV prevention is safe and effective in reducing HIV incidence. However, more evidence of PrEP knowledge, willingness and distribution preferences is required for scale-up among young people at-risk. Objective: To understand young people PrEP awareness, willingness and roll-out preferences. Methods: Young people (18–24y) were selected through multi-stage sampling in a cross-sectional household survey in low-income communities. Self-administered interviews collected participants’ data about PrEP awareness, attitudes, willingness and HIV-risk practices. Data were descriptively analysed by gender. Regression models assessed factors associated with PrEP awareness and willingness by district. Results: Of the 1917 participants interviewed 44.6% (men = 39.4% vs women = 49%, p = 0.001) were PrEP aware, 49.0% were willing to use PrEP. Participants most preferred PrEP distribution channels were public clinics (51.2%) and hospitals (23.8%). More men than women preferred distribution through schools (11.9% vs7.8%; p = 0.002) and NGOs (8.5%vs5.4%; p = 0.008). The biggest barrier to PrEP willingness was inadequate PrEP knowledge (10.0%) but more men than women disliked taking pills daily (4.1%vs2.0%; p-value = 0.007). Gendered determinants to use PrEP were side effects (51%; men = 47% vs women = 55%; p = 0.001) and pill effectiveness (29.5%; men = 26.4% vs women = 32.6%; p = 0.003). In both districts PrEP knowledge was associated with being female and media use. The associations between PrEP awareness and having multiple sexual partnerships, HIV knowledge, HIV self-test willingness and belonging to social clubs differed by district. PrEP willingness was positively associated with having TB and PrEP knowledge in each district but district differences were observed in media and occupation factors. Conclusions: The study shows young people’s low levels of PrEP awareness. It also shows relatively increased willingness, gendered PrEP awareness and distribution preferences. Promoting youth’s PrEP awareness requires a multifarious media strategy.

    Knowledge, attitudes and practices of young adults towards HIV prevention: an analysis of baseline data from a community-based HIV prevention intervention study in two high HIV burden districts, South Africa

    by Simukai Shamu, Sikhulile Khupakonke, Thato Farirai, Jean Slabbert, Thato Chidarikire, Geoffrey Guloba, Nkhensani Nkhwashu

    Background: With an HIV incidence of 1.00 skewed against women (1.51), adolescents in South Africa are at high HIV risk. This paper assesses young adults’ (18–24 years) knowledge, attitudes and practices regarding HIV prevention in Nkangala and OR Tambo districts. Methods: A cross-sectional household survey was conducted in two districts in 2017/8. Participants completed computer-assisted self-interviews on HIV knowledge, attitudes, behaviour practices, use of social media and condom use at last sex (proxy for high-risk sex). HIV knowledge was assessed using the South African-adapted UNAIDS scale. Descriptive analyses were conducted and logistic regression models were built to assess factors associated with being knowledgeable of HIV and condom use at last sex. Results: One thousand nine hundred fifty-five participants were interviewed (90% response rate). Less than half (44.7%) had correct knowledge of HIV prevention and 73% used a condom at last sex. Social media use predicted high HIV knowledge as higher odds were observed among participants using the print media (aOR1.87; 1.34–2.60), WhatsApp (aOR1.55; 1.26–1.90), radio/television (aOR2.75; 1.15–6.55) although social networking sites’ use protected against knowledge acquisition (aOR0.53; 0.34–0.82). Females (aOR0.75; 0.58–0.97) and participants reporting sexual risk were less likely to have HIV knowledge as negative associations were found for having multiple sexual partners in the last 3 months (aOR0.63;0.48–0.82) and ever having sex (aOR0.37;0.23–0.61). Participants who abused drugs (aOR1.40; 1.05–1.88) and had attitudes accepting people living with HIV (aOR2.05; 1.14–3.69) had higher odds of having HIV knowledge. Females (aOR0.70; 0.54–0.91), students (aOR0.52; 0.40–0.66) and participants who abused drugs (aOR0.58; 0.43–0.77) were less likely to report condom use at last sex. Conclusions: There is a correlation between media use and HIV knowledge, non-condom use and HIV knowledge, and high-risk sexual behaviours and less HIV knowledge. An aggressive community media campaign utilising locally available, preferred and accessible media platforms among young adults is required for behaviour change.

    Social franchising of community-based HIV counselling and testing services to increase HIV testing and linkage to care in Tshwane, South Africa: study protocol for a non-randomised implementation trial

    by Simukai Shamu, Charles Chasela, Jean Slabbert, Thato Farirai, Geoffrey Guloba, Nkhensani Nkhwashu

    Background: Meeting the ambitious UN 90–90-90 HIV testing, treatment and viral load suppression targets requires innovative strategies and approaches in Sub-Saharan Africa. To date no known interventions have been tested with community health workers (counsellors) as social franchisees or owner-managed businesses in Community-based HIV counselling and testing (CBCT) work. The aim of this methods paper is to describe a Social franchise (SF) CBCT implementation trial to increase HIV testing and linkage to care for individuals at community levels in comparison with an existing CBCT programme methods. Methods/design: This is a two arm non-randomised community implementation trial with a once off round of post-test follow-up per HIV positive participant to assess linkage to care in low income communities. The intervention arm is a social franchise CBCT in which unemployed, self-employed or employed community members are recruited, contracted and incentivised to test at least 100 people per month, identifying at least 5 HIV positive tests and linking to care at least 4 of them. Social franchisees receive approximately $3.20 per HIV test and $8 per client linked to care. In the control arm, full-time employed HIV counsellors conduct CBCT on a fixed monthly salary. Primary study outcomes are HIV testing uptake rate, HIV positivity, Linkage to care and treatment rate and average counsellors’ remuneration cost. Data collection will be conducted using both paper-based and electronic data applications by CBCT or SF counsellors. Data analysis will compare proportions of HIV testing, positivity, linkage to HIV care and treatment rates and counsellors’ cost in the two study arms. Discussion: The study will provide important insight into whether the SF-delivered CBCT programme increases testing coverage and linkage to care as well as reducing CBCT cost per HIV test and per HIV positive person linked to care. Trial registration: Pan African Clinical Trial Registry PACTR201809873079121. The trial was retrospectively registered on 11 September 2018.
