Systematic review exploring time trends in the association between educational attainment and risk of HIV infection in sub-Saharan Africa.

Objective:To assess the evidence that the association between educational attainment and risk of HIV infection is changing over time in sub-Saharan Africa. Design and methods:Systematic review of published peer-reviewed articles. Articles were identified that reported original data comparing individually measured educational attainment and HIV status among at least 300 individuals representative of the general population of countries or regions of sub-Saharan Africa. Statistical analyses were required to adjust for potential confounders but not over-adjust for variables on the causal pathway. Results:Approximately 4000 abstracts and 1200 full papers were reviewed. Thirty-six articles were included in the study, containing data on 72 discrete populations from 11 countries between 1987 and 2003, representing over 200 000 individuals. Studies on data collected prior to 1996 generally found either no association or the highest risk of HIV infection among the most educated. Studies conducted from 1996 onwards were more likely to find a lower risk of HIV infection among the most educated. Where data over time were available, HIV prevalence fell more consistently among highly educated groups than among less educated groups, in whom HIV prevalence sometimes rose while overall population prevalence was falling. In several populations, associations suggesting greater HIV risk in the more educated at earlier time points were replaced by weaker associations later. Discussion:HIV infections appear to be shifting towards higher prevalence among the least educated in sub-Saharan Africa, reversing previous patterns. Policy responses that ensure HIV-prevention measures reach all strata of society and increase education levels are urgently needed.

Barriers and facilitating factors to the uptake of antiretroviral drugs for prevention of mother-to-child transmission of HIV in sub-Saharan Africa:a systematic review

To investigate and synthesize reasons for low access, initiation and adherence to antiretroviral drugs by mothers and exposed babies for prevention of mother‐to‐child transmission (PMTCT) of HIV in sub‐Saharan Africa.

From affected to infected? Orphanhood and HIV risk among female adolescents in urban Zimbabwe.

Background:Despite the 15 million children orphaned by AIDS, and fears of sexual vulnerability, little is known about the link between orphanhood and HIV risk. Methods:A random sample of 1283 15 to 19-year-old girls in a high-density suburb of Harare was identified in a cross-sectional survey in 2004. A total of 863 agreed to be interviewed and 839 provided a specimen for HIV and herpes simplex virus type-2 (HSV-2) testing. Sexual health outcomes, sexual behaviours and marriage were assessed by type and timing of orphanhood. Results:Half of the participants were single or double orphans. Prevalence of HIV and/or HSV-2 was higher among orphans than non-orphans [17 versus 12%; age-adjusted odds ratio (aOR) = 1.5; 95% confidence interval (CI) 1.0–2.3]. Associations with orphan status were only significant among the 743 never-married participants. In comparison with non-orphaned peers, increased sexual risk (defined as HSV2-positive, HIV-positive or ever pregnant) was seen among maternal orphans (aOR = 3.6; 95% CI, 1.7–7.8), double orphans (aOR = 2.4; 95% CI, 1.2–4.9), and girls who lost their father before age 12 (aOR = 2.1; 95% CI, 0.9–4.8) but not later (aOR = 0.8; 95% CI, 0.3–2.2). Maternal and double orphans were most likely to initiate sex early and to have had multiple partners. Maternal orphans were least likely to have used a condom at first sex, and to have a regular sexual partner. Experience of forced sex was high in all groups. Conclusions:In urban Zimbabwe, female adolescent orphans are at increased risk of HIV and HSV-2 infection. Infection rates vary by type and age of orphanhood, and marital status, and are associated with high-risk sexual behaviours.

Study protocol for the Integra Initiative to assess the benefits and costs of integrating sexual and reproductive health and HIV services in Kenya and Swaziland.

BackgroundIn sub-Saharan Africa (SSA) there are strong arguments for the provision of integrated sexual and reproductive health (SRH) and HIV services. Most HIV transmissions are sexually transmitted or associated with pregnancy, childbirth, and breastfeeding. Many of the behaviours that prevent HIV transmission also prevent sexually transmitted infections and unintended pregnancies. There is potential for integration to increase the coverage of HIV services, as individuals who use SRH services can benefit from HIV services and vice-versa, as well as increase cost-savings. However, there is a dearth of empirical evidence on effective models for integrating HIV/SRH services. The need for robust evidence led a consortium of three organizations – International Planned Parenthood Federation, Population Council and the London School of Hygiene & Tropical Medicine – to design/implement the Integra Initiative. Integra seeks to generate rigorous evidence on the feasibility, effectiveness, cost and impact of different models for delivering integrated HIV/SRH services in high and medium HIV prevalence settings in SSA.Methods/designA quasi-experimental study will be conducted in government clinics in Kenya and Swaziland – assigned into intervention/comparison groups. Two models of service delivery are investigated: integrating HIV care/treatment into 1) family planning and 2) postnatal care. A full economic-costing will be used to assess the costs of different components of service provision, and the determinants of variations in unit costs across facilities/service models. Health facility assessments will be conducted at four time-periods to track changes in quality of care and utilization over time. A two-year cohort study of family planning/postnatal clients will assess the effect of integration on individual outcomes, including use of SRH services, HIV status (known/unknown) and pregnancy (planned/unintended). Household surveys within some of the study facilities’ catchment areas will be conducted to profile users/non-users of integrated services and demand/receipt of integrated services, before-and-after the intervention. Qualitative research will be conducted to complement the quantitative component at different time points. Integra takes an embedded ‘programme science’ approach to maximize the uptake of findings into policy/practice.DiscussionIntegra addresses existing evidence gaps in the integration evaluation literature, building on the limited evidence from SSA and the expertise of its research partners.Trial registrationCurrent Controlled Trials NCT01694862

Intimate Partner Violence and Socioeconomic Deprivation in England: Findings From a National Cross-Sectional Survey

OBJECTIVES We examined the prevalence of intimate partner violence (IPV) and its association with social deprivation in England. METHODS We used multivariable logistic regression to investigate IPV correlates among 21 226 men and women aged 16 to 59 years in the 2008 nationally representative cross-sectional British Crime Survey. RESULTS Lifetime IPV was reported by 23.8% of women and 11.5% of men. Physical IPV was reported by 16.8% and 7.0%, respectively; emotional-only IPV was reported by 5.8% and 4.2%, respectively. After adjustment for demographic confounders, lifetime physical IPV experienced by women was associated with social housing tenure (odds ratio [OR] = 2.3; 95% confidence interval [CI] = 2.0, 2.7), low household income (OR = 2.2; 95% CI = 1.8, 2.7), poor educational attainment (OR = 1.2; 95% CI = 1.0, 1.5), low social class (OR = 1.5; 95% CI = 0.3, 1.7), and living in a multiply deprived area (OR = 1.4; 95% CI = 1.1, 1.7). Physical IPV experienced by men and emotional IPV experienced by either gender were generally not associated with deprivation factors. CONCLUSIONS Physical and emotional IPV are very common among adults in England. Emotional IPV prevention policies may be appropriate across the social spectrum; those for physical IPV should be particularly accessible to disadvantaged women.

“It Is Like That, We Didn't Understand Each Other”: Exploring the Influence of Patient-Provider Interactions on Prevention of Mother-To-Child Transmission of HIV Service Use in Rural Tanzania

Interactions between patients and service providers frequently influence uptake of prevention of mother-to-child transmission (PMTCT) HIV services in sub-Saharan Africa, but this process has not been examined in depth. This study explores how patient-provider relations influence PMTCT service use in four government facilities in Kisesa, Tanzania. Qualitative data were collected in 2012 through participatory group activities with community members (3 male, 3 female groups), in-depth interviews with 21 women who delivered recently (16 HIV-positive), 9 health providers, and observations in antenatal clinics. Data were transcribed, translated into English and analysed with NVIVO9 using an adapted theoretical model of patient-centred care. Three themes emerged: decision-making processes, trust, and features of care. There were few examples of shared decision-making, with a power imbalance in favour of providers, although they offered substantial psycho-social support. Unclear communication by providers, and patients not asking questions, resulted in missed services. Omission of pre-HIV test counselling was often noted, influencing womens ability to opt-out of HIV testing. Trust in providers was limited by confidentiality concerns, and some HIV-positive women were anxious about referrals to other facilities after establishing trust in their original provider. Good care was recounted by some women, but many (HIV-positive and negative) described disrespectful staff including discrimination of HIV-positive patients and scolding, particularly during delivery; exacerbated by lack of materials (gloves, sheets) and associated costs, which frustrated staff. Experienced or anticipated negative staff behaviour influenced adherence to subsequent PMTCT components. Findings revealed a pivotal role for patient-provider relations in PMTCT service use. Disrespectful treatment and lack of informed consent for HIV testing require urgent attention by PMTCT programme managers. Strategies should address staff behaviour, emphasizing ethical standards and communication, and empower patients to seek information about available services. Optimising provider-patient relations can improve uptake of maternal health services more broadly, and ART adherence.

Using vignettes in qualitative research to explore barriers and facilitating factors to the uptake of prevention of mother-to-child transmission services in rural Tanzania: a critical analysis

BackgroundVignettes are short stories about a hypothetical person, traditionally used within research (quantitative or qualitative) on sensitive topics in the developed world. Studies using vignettes in the developing world are emerging, but with no critical examination of their usefulness in such settings. We describe the development and application of vignettes to a qualitative investigation of barriers to uptake of prevention of mother-to-child transmission (PMTCT) HIV services in rural Tanzania in 2012, and critique the successes and challenges of using the technique in this setting.MethodsParticipatory Learning and Action (PLA) group activities (3 male; 3 female groups from Kisesa, north-west Tanzania) were used to develop a vignette representing realistic experiences of an HIV-infected pregnant woman in the community. The vignette was discussed during in-depth interviews with 16 HIV-positive women, 3 partners/relatives, and 5 HIV-negative women who had given birth recently. A critical analysis was applied to assess the development, implementation and usefulness of the vignette.ResultsThe majority of in-depth interviewees understood the concept of the vignette and felt the story was realistic, although the story or questions needed repeating in some cases. In-depth interviewers generally applied the vignette as intended, though occasionally were unsure whether to steer the conversation back to the vignette character when participants segued into personal experiences. Interviewees were occasionally confused by questions and responded with what the character should do rather than would do; also confusing fieldworkers and presenting difficulties for researchers in interpretation. Use of the vignette achieved the main objectives, putting most participants at ease and generating data on barriers to PMTCT service uptake. Participants’ responses to the vignette often reflected their own experience (revealed later in the interviews).ConclusionsParticipatory group research is an effective method for developing vignettes. A vignette was incorporated into qualitative interview discussion guides and used successfully in rural Africa to draw out barriers to PMTCT service use; vignettes may also be valuable in HIV, health service use and drug adherence research in this setting. Application of this technique can prove challenging for fieldworkers, so thorough training should be provided prior to its use.

Innovation in Evaluating the Impact of Integrated Service-Delivery: The Integra Indexes of HIV and Reproductive Health Integration

Background The body of knowledge on evaluating complex interventions for integrated healthcare lacks both common definitions of ‘integrated service delivery’ and standard measures of impact. Using multiple data sources in combination with statistical modelling the aim of this study is to develop a measure of HIV-reproductive health (HIV-RH) service integration that can be used to assess the degree of service integration, and the degree to which integration may have health benefits to clients, or reduce service costs. Methods and Findings Data were drawn from the Integra Initiative’s client flow (8,263 clients in Swaziland and 25,539 in Kenya) and costing tools implemented between 2008–2012 in 40 clinics providing RH services in Kenya and Swaziland. We used latent variable measurement models to derive dimensions of HIV-RH integration using these data, which quantified the extent and type of integration between HIV and RH services in Kenya and Swaziland. The modelling produced two clear and uncorrelated dimensions of integration at facility level leading to the development of two sub-indexes: a Structural Integration Index (integrated physical and human resource infrastructure) and a Functional Integration Index (integrated delivery of services to clients). The findings highlight the importance of multi-dimensional assessments of integration, suggesting that structural integration is not sufficient to achieve the integrated delivery of care to clients—i.e. “functional integration”. Conclusions These Indexes are an important methodological contribution for evaluating complex multi-service interventions. They help address the need to broaden traditional evaluations of integrated HIV-RH care through the incorporation of a functional integration measure, to avoid misleading conclusions on its ‘impact’ on health outcomes. This is particularly important for decision-makers seeking to promote integration in resource constrained environments.

Integration of HIV and maternal healthcare in a high HIV-prevalence setting: analysis of client flow data over time in Swaziland

Objective Maternal and child health (MCH) care may provide an entry point for HIV services in high HIV-prevalence settings. Our objective was to assess integration of HIV with MCH services in public sector facilities in Swaziland. Design In 2009, 2010 and 2012, client flow assessments (CFAs) were conducted over 5 days in the MCH units of eight government facilities, purposively selected as intervention or comparison sites. Participants 8263 MCH visits with female clients were tracked: 3261 in 2009, 2086 in 2010 and 2916 in 2012. Intervention Activities and resources to strengthen integration of HIV services into postnatal care (PNC), 2009–2010. Main outcome measures The proportion of all visits in which an HIV/sexually transmitted infection (STI) testing, counselling or treatment was received together with an MCH service; the proportion of all visits in which a client receives HIV counselling. Results Across facilities, the proportion of visits in which HIV/STI and MCH services were received varied considerably, for example, from 9% to 49% in 2009. HIV/STI services were integrated most frequently with child health (CH), antenatal care (ANC) and family planning (FP)—the most common reasons for womens attendance—and least often with PNC and cervical screening (CS). There was no meaningful difference in integration over time by design group and considerable heterogeneity across facilities. Receipt of integrated services increased in one intervention and two comparison facilities, where HIV counselling also rose, and fell in one intervention and two comparison facilities. Conclusions Provision of HIV/STI services with MCH care occurred at all facilities, yet relatively few women receive integrated services. Increases in integration were driven by increases in HIV counselling, while sharp declines in some facilities indicate that integration is difficult to sustain. Opportunities for intensifying HIV integration lie with ANC, CH and FP, while HIV-PNC integration will remain limited until more women attend PNC.

Need demand and missed opportunities for integrated reproductive health–HIV care in Kenya and Swaziland: evidence from household surveys.

Objective:Little is known about the need and demand for integrated reproductive health and HIV services at the population level. Design:Descriptive data analysis of household surveys collected by the Integra Initiative. Methods:Household surveys were conducted among 18–49-year-olds in Kenya (N = 1752) and Swaziland (N = 779) in 2009. Data on fertility intentions, contraceptive use, sexual behaviours and HIV testing were used to determine unmet needs. Demand for integrated services was defined as wanting reproductive health services with HIV/sexually transmitted infection (STI) services within one visit. Results:At the population level, family planning needs (90%) were higher than HIV/STI prevention needs: 53% (women) and 75% (men). Fewer had unmet family planning needs through non-use of contraceptives: 17% (women) and 27% (men); versus unmet HIV/STI prevention needs through inconsistent condom use: 48 and 26% of women; 51 and 32% of men in Kenya and Swaziland, respectively. Dual need was higher for men: 64% (Kenya) and 73% (Swaziland) versus women (48%) with more unmet in Kenya (43%) compared to Swaziland (25%). Missed opportunities for integrated service provision were high among women: 49 and 57% with unmet family planning needs; and 55 and 32% with unmet HIV/STI prevention needs in Kenya and Swaziland, respectively, used services, but did not receive the needed service. Most men with unmet needs were non-service users. Approximately a quarter of women wanted and received integrated reproductive health–HIV/STI services in both countries. Conclusions:Demand creation at the community level and provider-initiated integrated service provision are needed, using different strategies for men and women, to address substantial family planning and HIV/STI prevention needs.
