Intimate partner violence, relationship power inequity, and incidence of HIV infection in young women in South Africa: a cohort study

BACKGROUND Cross-sectional studies have shown that intimate partner violence and gender inequity in relationships are associated with increased prevalence of HIV in women. Yet temporal sequence and causality have been questioned, and few HIV prevention programmes address these issues. We assessed whether intimate partner violence and relationship power inequity increase risk of incident HIV infection in South African women. METHODS We did a longitudinal analysis of data from a previously published cluster-randomised controlled trial undertaken in the Eastern Cape province of South Africa in 2002-06. 1099 women aged 15-26 years who were HIV negative at baseline and had at least one additional HIV test over 2 years of follow-up were included in the analysis. Gender power equity and intimate partner violence were measured by a sexual relationship power scale and the WHO violence against women instrument, respectively. Incidence rate ratios (IRRs) of HIV acquisition at 2 years were derived from Poisson models, adjusted for study design and herpes simplex virus type 2 infection, and used to calculate population attributable fractions. FINDINGS 128 women acquired HIV during 2076 person-years of follow-up (incidence 6.2 per 100 person-years). 51 of 325 women with low relationship power equity at baseline acquired HIV (8.5 per 100 person-years) compared with 73 of 704 women with medium or high relationship power equity (5.5 per 100 person-years); adjusted multivariable Poisson model IRR 1.51, 95% CI 1.05-2.17, p=0.027. 45 of 253 women who reported more than one episode of intimate partner violence at baseline acquired HIV (9.6 per 100 person-years) compared with 83 of 846 who reported one or no episodes (5.2 per 100 person-years); adjusted multivariable Poisson model IRR 1.51, 1.04-2.21, p=0.032. The population attributable fractions were 13.9% (95% CI 2.0-22.2) for relationship power equity and 11.9% (1.4-19.3) for intimate partner violence. INTERPRETATION Relationship power inequity and intimate partner violence increase risk of incident HIV infection in young South African women. Policy, interventions, and programmes for HIV prevention must address both of these risk factors and allocate appropriate resources.

Impact of Stepping Stones on incidence of HIV and HSV-2 and sexual behaviour in rural South Africa: cluster randomised controlled trial

Objective To assess the impact of Stepping Stones, a HIV prevention programme, on incidence of HIV and herpes simplex type 2 (HSV-2) and sexual behaviour. Design Cluster randomised controlled trial. Setting 70 villages (clusters) in the Eastern Cape province of South Africa. Participants 1360 men and 1416 women aged 15-26 years, who were mostly attending schools. Intervention Stepping Stones, a 50 hour programme, aims to improve sexual health by using participatory learning approaches to build knowledge, risk awareness, and communication skills and to stimulate critical reflection. Villages were randomised to receive either this or a three hour intervention on HIV and safer sex. Interviewers administered questionnaires at baseline and 12 and 24 months and blood was tested for HIV and HSV-2. Main outcome measures Primary outcome measure: incidence of HIV. Other outcomes: incidence of HSV-2, unwanted pregnancy, reported sexual practices, depression, and substance misuse. Results There was no evidence that Stepping Stones lowered the incidence of HIV (adjusted incidence rate ratio 0.95, 95% confidence interval 0.67 to 1.35). The programme was associated with a reduction of about 33% in the incidence of HSV-2 (0.67, 0.46 to 0.97; P=0.036)—that is, Stepping Stones reduced the number of new HSV-2 infections over a two year period by 34.9 (1.6 to 68.2) per 1000 people exposed. Stepping Stones significantly improved a number of reported risk behaviours in men, with a lower proportion of men reporting perpetration of intimate partner violence across two years of follow-up and less transactional sex and problem drinking at 12 months. In women desired behaviour changes were not reported and those in the Stepping Stones programme reported more transactional sex at 12 months. Conclusion Stepping Stones did not reduce incidence of HIV but had an impact on several risk factors for HIV—notably, HSV-2 and perpetration of intimate partner violence. Trial Registration Clinical Trials NCT00332878.

Perpetration of partner violence and HIV risk behaviour among young men in the rural Eastern Cape, South Africa

Objectives:To examine associations between the perpetration of intimate partner violence and HIV risk behaviour among young men in rural South Africa. Design:An analysis of baseline data from men enrolling in a randomized controlled trial of the behavioural intervention, Stepping Stones. Methods:Structured interviews with 1275 sexually experienced men aged 15–26 years from 70 villages in the rural Eastern Cape. Participants were asked about the type, frequency, and timing of violence against female partners, as well as a range of questions about HIV risk behaviours. Results:A total of 31.8% of men reported the perpetration of physical or sexual violence against female main partners. Perpetration was correlated with higher numbers of past year and lifetime sexual partners, more recent intercourse, and a greater likelihood of reporting casual sex partners, problematic substance use, sexual assault of non-partners, and transactional sex. Men who reported both physical and sexual violence against a partner, perpetration both before and within the past 12 months, or more than one episode of perpetration reported significantly higher levels of HIV risk behaviour than men who reported less severe or less frequent perpetration of violence. Conclusion:Young men who perpetrate partner violence engage in significantly higher levels of HIV risk behaviour than non-perpetrators, and more severe violence is associated with higher levels of risky behaviour. HIV prevention interventions must explicitly address the links between the perpetration of intimate partner violence and HIV risk behaviour among men, as well as the underlying gender and power dynamics that contribute to both.

Associations between childhood adversity and depression, substance abuse and HIV and HSV2 incident infections in rural South African youth

OBJECTIVES To describe prevalence of childhood experiences of adversity in rural South African youth and their associations with health outcomes. METHODS We analyzed questionnaires and blood specimens collected during a baseline survey for a cluster randomized controlled trial of a behavioral intervention, and also tested blood HIV and herpes simplex type 2 virus at 12- and 24-month follow up; 1,367 male and 1,415 female volunteers were recruited from 70 rural villages. RESULTS Both women and men before 18 had experienced physical punishment (89.3% and 94.4%), physical hardship (65.8% and 46.8%), emotional abuse (54.7% and 56.4%), emotional neglect (41.6% and 39.6%), and sexual abuse (39.1% and 16.7%). Incident HIV infections were more common in women who experienced emotional abuse (IRR 1.96, 95% CI 1.25, 3.06, p=.003), sexual abuse (IRR 1.66 95% CI 1.04, 2.63, p=.03), and physical punishment (IRR 2.13 95% CI 1.04, 4.37, p=.04). Emotional neglect in women was associated with depression (aOR 1.82, 95% CI 1.15, 2.88, p=.01), suicidality (aOR 5.07, 95% CI 2.07, 12.45, p<.0001), alcohol abuse (aOR 2.17, 95% CI .99, 4.72, p=.05), and incident HSV2 infections (IRR 1.62, 95% CI 1.01, 2.59, p=.04). In men emotional neglect was associated with depression (aOR 3.41, 95% CI 1.87, 6.20, p<.0001) and drug use (aOR 1.98, 95% CI 1.37, 2.88, p<.0001). Sexual abuse was associated with alcohol abuse in men (aOR 3.68, 95% CI 2.00, 6.77, p<.0001) and depression (aOR 2.16, 95% CI 1.34, 3.48, p=.002) and alcohol abuse in women (aOR 3.94, 95% CI 1.90, 8.17, p<.0001). PRACTICE IMPLICATIONS Childhood exposure to adversity is very common and influences the health of women and men. All forms of adversity, emotional, physical and sexual, enhance the risk of adverse health outcomes in men and women. Prevention of child abuse need to be included as part of the HIV prevention agenda in sub-Saharan Africa. Interventions are needed to prevent emotional, sexual, and physical abuse and responses from health and social systems in Africa to psychologically support exposed children must be strengthened.

Associations between depressive symptoms, sexual behaviour and relationship characteristics: a prospective cohort study of young women and men in the Eastern Cape, South Africa

BackgroundPsychological factors are often neglected in HIV research, although psychological distress is common in low- to middle-income countries, such as South Africa. There is a need to deepen our understanding of the role of mental health factors in the HIV epidemic. We set out to investigate whether baseline depressive symptomatology was associated with risky sexual behaviour and relationship characteristics of men and women at baseline, as well as those found 12 months later.MethodsWe used prospective cohort data from a cluster randomized controlled trial of an HIV prevention intervention in the Eastern Cape Province of South Africa. Our subjects were 1002 female and 976 male volunteers aged 15 to 26. Logistic regression was used to model the cross-sectional and prospective associations between baseline depressive symptomatology, risky sexual behaviors and relationship characteristics. The analysis adjusted for the clustering effect, study design, intervention and several confounding variables.ResultsPrevalence of depressive symptoms was 21.1% among women and 13.6% among men. At baseline, women with depressed symptoms were more likely to report lifetime intimate partner violence (AOR = 2.56, 95% CI 1.89-3.46) and have dated an older partner (AOR = 1.37, 95% CI 1.03-1.83). A year later, baseline depressive symptomatology was associated with transactional sex (AOR = 2.60, 95% CI 1.37, 4.92) and intimate partner violence (AOR = 1.67, 95% CI 1.18-2.36) in the previous 12 months. Men with depressive symptoms were more likely to report ever having had transactional sex (AOR = 1.48, 95% CI 1.01-2.17), intimate partner violence perpetration (AOR = 1.50, 95% CI 0.98-2.28) and perpetration of rape (AOR = 1.81, 95% CI 1.14-2.87). They were less likely to report correct condom use at last sex (AOR = 0.50, 95% CI 0.32-0.78). A year later, baseline depressive symptomatology was associated with failure to use a condom at last sex among men (AOR = 0.60, 95% CI 0.40-0.89).ConclusionsSymptoms of depression should be considered as potential markers of increased HIV risk and this association may be causal. HIV prevention needs to encompass promotion of adolescent mental health.

Women Living with HIV in South Africa and Their Concerns About Fertility

Health and quality of life benefits accrued from the availability of highly active antiretroviral therapy (HAART) are commendable, but the social milieu continues to pose challenges for women’s decision making around having children. This paper qualitatively explored women’s questions and concerns around living with HIV, being on HAART and pregnancy. Women of reproductive age were recruited from Eastern Cape and Gauteng Provinces, South Africa. Information on women’s fertility desires and pregnancy planning was collected through participatory workshop, focus groups, and one-on-one interviews. Three main themes emerged. Women living with HIV require information on the impact of HIV on pregnancy outcomes and vice versa. Women who are young, lost a child, not consistently using contraception or who have not been seriously ill have positive reproductive aspirations. Ambivalent attitudes of health care workers towards pregnancy impacts women’s fertility aspirations. Unbiased pre-conceptual communication should form part of HIV treatment and care services, despite expressed pregnancy intentions.

Masculinities and condom use patterns among young rural South Africa men: a cross-sectional baseline survey

BackgroundNotions of ideal manhood in South Africa are potentially prescriptive of male sexuality thus accounting for the behaviors which may lead to men being at greater HIV risk. We tested the hypothesis that gender and relationship constructs are associated with condom use among young men living in rural South Africa.Methods1219 men aged 15–26 years completed a cross-sectional baseline survey from an IsiXhosa questionnaire asking about sexual behaviour and relationships. Univariate and bivariate analyses described condom use patterns and explanatory variables, and multinomial regression modeling assessed the factors associated with inconsistent versus consistent and non-condom use.Results47.7% of men never used condoms, when 36.9% were inconsistent and 15.4% were consistent with any partner in the past year. Condom use patterns differed in association with gender relations attitudes: never users were significantly more conservative than inconsistent or consistent users. Three gender positions emerged indicating that inconsistent users were most physically/sexually violent and sexually risky; never users had more conservative gender attitudes but were less violent and sexually risky; and consistent users were less conservative, less violent and sexually risky with notably fewer sexual partners than inconsistent users.ConclusionsThe confluence of conservative gender attitudes, perpetration of violence against women and sexual risk taking distinguished inconsistent condom users as the most risky compared to never condom users, and rendered inconsistent use one of the basic negative attributes of dominant masculinities in the Eastern Cape, South Africa. This finding is important for the design of HIV prevention and gender equity interventions and emphasizes the need for a wider roll-out of interventions that promote progressive and healthy masculine practices in the country.

Transactional Sex and HIV Incidence in a Cohort of Young Women in the Stepping Stones Trial

Background: Structural drivers of the HIV epidemic are increasingly recognised, and cross-sectional research has shown an association between transactional sex and HIV prevalence, but evidence on the impact of transactional sex on HIV incidence in young women remains limited. Methods: We tested hypotheses that transactional sex predicted incident HIV infections in a dataset of 1077 HIV negative women aged 15-26 enrolled in a cluster randomised controlled trial. Incidence rate ratios were derived from multivariable Poisson models which included terms for age, HSV2, relationship power, condom use, intimate partner violence (IPV) exposure, treatment, stratum and person years of exposure to HIV. Results: 127 sexually active women acquired HIV during the study. HIV incidence was greater among women having transactional sex with a once off partner (IRR 3.29 95% CI 1.02, 10.55, p=0.046) and those having transactional sex with an on-going, concurrent partner (IRR 2.05 95% CI 1.20, 3.52, p=0.009). An analysis was performed to distinguish between the effects of a transactional sexual encounter or relationship and having a higher number of sexual partners or older partners, which are usually entailed in transactional sex. Women having transactional sex with a casual partner (on-going or once off) and two or more partners during follow up had an elevated risk of HIV acquisition (IRR 2.23 95% CI 1.28, 3.88, p=0.005), where as those just having two or more partners did not (IRR 1.20 95% CI 0.81, 1.77, p=0.368). Women with partners 5 or more years older did not have an elevated risk of HIV. Conclusions: Transactional sex with an on-going or once off partner elevates young women’s risk of HIV infection. This finding is independent of partner number or age. These findings support the need for structural interventions in HIV prevention, with a stronger focus on reducing transactional sex.

Factors associated with consistent condom use among rural young women in South Africa

Abstract Despite high levels of awareness of HIV, condom use, particularly consistent use, is suboptimal among young South African women. This paper aims to investigate the factors associated with both any condom use and consistent use by young rural women. In this study 1204 sexually active female volunteers, aged 15–26 years, were selected using a two-stage procedure in which firstly 70 clusters were selected and thereafter up to 20 women per cluster were selected, to participate in a cluster randomised controlled trial of an HIV behavioural intervention. This study is analysing cross-sectional data from a baseline survey thus no causal inferences can be drawn. A structured questionnaire was administered at a baseline interview. An estimated 19.9% of young women reported consistent condom use in the 12 months before the interview, while 44.5% reported inconsistent use. Any condom use was associated with higher condom use self-efficacy (adjusted odds ratio (aOR) 1.59; 95% CI 1.41, 1.77), less association of trust with suggested condom use (aOR 0.86; 95% CI 0.82, 0.91), knowing ones HIV status (aOR 2.86; 95% CI 1.52, 5.39) and having a more educated mother (aOR 1.71; 95% CI 1.26, 2.33). Having had just one partner was associated with a lesser likelihood of any condom use (aOR 0.14; 95% CI 0.10, 0.20). Consistent use, compared with inconsistent use, was associated with having just one partner (aOR 3.25; 95% CI 2.23, 4.73), less relationship conflict (aOR 0.84; 95% CI 0.75, 0.91) and higher gender equity in relationships with a male partner (aOR 1.43; 95% CI 1.15, 1.77). Our findings suggest that gender equity, monogamy and harmonious relationships play a positive role in enabling women to reduce their risk for HIV infection. Such aspects of relationship context could form a significant part of the progressive strategies required for HIV-prevention interventions to be successful.
