Title: Inequalities in uptake of HIV testing despite scale-up

Authors:

Euphemia L Sibanda, Miriam Taegtmeyer

Abstract

HIV testing is an essential aspect of HIV prevention and treatment services. Since 2008, large-scale initiatives have aimed to increase access to, and uptake of, HIV testing in untested populations at risk. Strategies have included provider-initiated HIV testing and counselling, community-based approaches, and partner notifi-cation. Sub-Saharan Africa, the region worst affected by the HIV epidemic, is also the region most in need of these initiatives. Similar to findings for other health interventions, inequalities in uptake of HIV testing have been recorded, and these inequalities might persist despite intensification of HIV testing efforts and scale-up of treatment.

Abstract:

Male involvement in maternal and child health is recognised as a valuable strategy to improve care-seeking and uptake of optimal home care practices for women and children in low- and middle-income settings. However, the specific mechanisms by which involving men can lead to observed behaviour change are not well substantiated. A qualitative study conducted to explore men’s and women’s experiences of male involvement interventions in Tanzania and Zimbabwe found that, for some women and men, the  interventions had fostered more loving partner relationships. Both male and female participants identified these changes as profoundly meaningful and highly valued. Our findings illustrate key pathways by which male involvement interventions were able to improve couples’ emotional relationships. Findings also indicate that these positive impacts on couple relationships can motivate and support men’s behaviour change, to improve care-seeking and home care practices. Men’s and women’s subjective experiences of partner relationships following male involvement interventions have not been well documented to date. Findings highlight the importance of increased love, happiness and emotional intimacy in couple relationships – both as a wellbeing outcome valued by men and women, and as a contributor to the effectiveness of male involvement interventions.

Title: Three lessons for the COVID-19 response from pandemic HIV

Author: 

*James Hargreave etal

Abstract:

The HIV pandemic provides lessons for the response to the novel coronavirus disease 2019 (COVID-19) pandemic: no vaccine is available for either and there are no licensed pharmaceuticals for COVID-19, just as there was not for HIV infection in the early years. Population behaviour will determine the pandemic trajectory of COVID-19, just as it did for HIV

Abstract:

Despite a growing body of literature on HIV service costs in sub-Saharan Africa, only a few studies have estimated the facility-level cost of prevention of Mother-to-Child Transmission (PMTCT) services, and even fewer provide insights into the variation of MTCT costs across facilities. In this study, we present the first empirical costs estimation of the accelerated program for the prevention of mother-to-child transmission of HIV in Zimbabwe and investigate the determinants of heterogeneity of the facility-level average cost per service. To understand such variation, we explored the association between average costs per service and supply-and demand-side characteristics, and quality of services. One aspect of the supply-side we explore carefully is the scale of production—which we define as the annual number of women tested or the yearly number of HIV-positive women on prophylaxis

Abstract
Young female sex-workers (FSW) aged 18–24 are at high risk of HIV due to high numbers of sexual partners, difficulty negotiating condom use, increased risk of gender-based violence, and limited access to services. Here we describe changes in sexual behaviours among young FSW across Zimbabwe between 2013 and 2016, and risk factors for prevalent HIV in 2013 and 2016. FSW ≥ 18 years were recruited using respondent-driven sampling in 14 sites across Zimbabwe in 2013 and 2016 as part of the SAPPH-IRe trial

Abstract

WHO recommends that HIV infected women receive antiretroviral therapy (ART) minimally during pregnancy and breastfeeding (“Option B”), or ideally throughout their lives regardless of clinical stage (“Option B+”) (Coovadia et al., Lancet 379:221–228, 2012). Although these recommendations were based on clinical trials demonstrating the efficacy of ART during pregnancy and breastfeeding, the population-level effectiveness of Option B+ is unknown.

Abstract

The prevalence of undiagnosed HIV is declining in Africa, and various HIV testing approaches are finding lower positivity rates. In this context, the epidemiological impact and cost-effectiveness of community-based HIV self-testing (CBHIVST)
is unclear. We aimed to assess this in different sub-populations and across scenarios characterized by different adult HIV prevalence and antiretroviral treatment programmes in sub-Saharan Africa.

Title: Applying user preferences to optimize the contribution of HIV self-testing to reaching the “first 90” target of UNAIDS Fast-track strategy: results from discrete choice experiments in Zimbabwe

Authors: Euphemia L Sibanda, Marc d’Elbee, Galven Maringwa, Nancy Ruhode, Mary Tumushime, Claudius Madanhire, Jason J Ong, Pitchaya Indravudh,  Constancia Watadzaushe, Cheryl C Johnson, Karin Hatzold7, Miriam Taegtmeyer, James R Hargreaves, Elizabeth L Corbett, Frances M Cowan and Fern Terris-Prestholt

Abstract

New HIV testing strategies are needed to reach the United Nations’ 90-90-90 target. HIV self-testing (HIVST) can increase uptake, but users’ perspectives on optimal models of distribution and post-test services are uncertain. We used discrete choice experiments (DCEs) to explore the impact of service characteristics on uptake along the testing cascade.

Abstract

UNAIDS’ goal of ending AIDS by 2030 is unreachable without better targeting of testing, prevention and care. Female sex workers (FSW) in Zimbabwe are at high risk of HIV acquisition and transmission. Here, we report on collated programme and research data from Zimbabwe’s national sex work programme. We also assess the potential for wider population impact of FSW programmes by modelling the impact on HIV incidence of eliminating transmission through FSW (i.e. calculate the population attributable fraction of incidence attributable to sex work).

Title: HIV risk among young women who sell sex by whether they identify as sex workers: analysis of respondent-driven sampling surveys, Zimbabwe, 2017

Authors: Bernadette Hensen , Sungai T Chabata , Sian Floyd, Tarisai Chiyaka, Phillis Mushati, Joanna Busza, Isolde Birdthistle , James R Hargreaves and Frances M Cowan

Abstract

Across sub-Saharan Africa, selling sex puts young women at high risk of HIV. Some young women who sell sex (YWSS) may self-identify as sex workers, while others may not, having implications for how to reach them with HIV prevention. We describe characteristics, sexual behaviours and health service use of YWSS in Zimbabwe, comparing women who identified as female sex workers (FSW) and women who did not (non-identifying-YWSS), and explore factors associated with HIV infection.
