    A systematic review of qualitative evidence on factors enabling and deterring uptake of HIV self-testing in Africa
    (2019-10-15) Njau, Bernard; Covin, Christopher; Lisasi, Esther; Damian, Damian; Mushi, Declare; Boulle, Andrew; Mathews, Catherine
    Abstract Background More than 40% of adults in Sub-Saharan Africa are unaware of their HIV status. HIV self-testing (HIVST) is a novel approach with a potential to increase uptake of HIV testing and linkage to care for people who test HIV positive. We explored HIV stakeholder’s perceptions about factors that enable or deter the uptake of HIV self-testing and experiences of self-testing of adult users in Africa. Methods This systematic review of qualitative evidence included articles on qualitative studies published or made available between January 1998 to February 2018 on perspectives of key stakeholders, including HIV policymakers, HIV experts, health care providers, and adult men and women (18 years and above) about factors that enable or deter the uptake of HIV self-testing and experiences of self-testing among adult users. We searched CINAHL, MEDLINE in Pubmed, EMBASE, AJOL, PsycINFO, Social Science Citation Index (SSCI), and Web of Science for articles in English on HIVST with qualitative data from different African countries. Results In total, 258 papers were retrieved, and only nine (9) studies conducted in 5 African countries were eligible and included in this synthesis. Perceived facilitators of the uptake of HIVST were autonomy and self-empowerment, privacy, confidentiality, convenience, opportunity to test, including couples HIV testing, and ease of use. The perceived barriers included the cost of buying self-test kits, perceived unreliability of test results, low literacy, fear and anxiety of a positive test result, and potential psychological and social harms. HIV stakeholder’s concerns about HIVST included human right issues, lack of linkage to care, lack of face-to-face counseling, lack of regulatory and quality assurance systems, and quality of self-test kits. Actual HIVST users expressed preference of oral-fluid self-testing because of ease of use, and that it is less invasive and painless compared to finger-stick/whole blood-based HIV tests. Lack of clear instructions on how to use self-test kits, and existing different products of HIVST increases rates of user errors. Conclusions Overcoming factors that may deter HIV testing, and HIVST, in particular, is complex and challenging, but it has important implications for HIV stakeholders, HIVST users, and public health in general. Research is warranted to explore the actual practices related to HIVST among different populations in Africa.

    Accuracy and determinants of perceived HIV risk among young women in South Africa
    (2018) Venkataramani, Atheendar S
    Abstract Background HIV risk perceptions are a key determinant of HIV testing. The success of efforts to achieve an AIDS-free generation – including reaching the UNAIDS 90–90-90 target – thus depends critically on the content of these perceptions. We examined the accuracy of HIV-risk perceptions and their correlates among young black women in South Africa, a group with one of the highest HIV incidence rates worldwide. Methods We used individual-level longitudinal data from the Cape Area Panel Study (CAPS) from 2005 to 2009 on black African women (20–30 years old in 2009) to assess the association between perceived HIV-risk in 2005 and the probability of testing HIV-positive four years later. We then estimated multivariable logistic regressions using cross-sectional data from the 2009 CAPS wave to assess the relationship between risk perceptions and a wide range of demographic, sexual behaviour and psychosocial covariates of perceived HIV-risk. Results We found that the proportion testing HIV-positive in 2009 was almost identical across perceived risk categories in 2005 (no, small, moderate, great) (χ 2 = 1.43, p = 0.85). Consistent with epidemiologic risk factors, the likelihood of reporting moderate or great HIV-risk perceptions was associated with condom-use (aOR: 0.57; 95% CI: 0.36, 0.89; p < 0.01); having ≥3 lifetime partners (aOR: 2.38, 95% CI: 1.53, 3.73; p < 0.01); knowledge of one’s partner’s HIV status (aOR: 0.67; 95% CI: 0.43, 1.07; p = 0.09); and being in an age-disparate partnerships (aOR: 1.73; 95% CI: 1.09, 2.76; p = 0.02). However, the likelihood of reporting moderate or great self-perceived risk did not vary with sexually transmitted disease history and respondent age, both strong predictors of HIV risk in the study setting. Risk perceptions were associated with stigmatising attitudes (aOR: 0.53; 95% CI: 0.26, 1.09; p = 0.09); prior HIV testing (aOR: 0.21; 95% CI: 0.13, 0.35; p < 0.01); and having heard that male circumcision is protective (aOR: 0.38; 95% CI: 0.22, 0.64; p < 0.01). Conclusions Results indicate that HIV-risk perceptions are inaccurate. Our findings suggest that this inaccuracy stems from HIV-risk perceptions being driven by an incomplete understanding of epidemiological risk and being influenced by a range of psycho-social factors not directly related to sexual behaviour. Consequently, new interventions are needed to align perceived and actual HIV risk.

    Evaluation of the Tsima community mobilization intervention to improve engagement in HIV testing and care in South Africa: study protocol for a cluster randomized trial
    (2017) Lippman, Sheri A; Pettifor, Audrey; Rebombo, Dumisani; Julien, Aimée; Wagner, Ryan G; Kang Dufour, Mi-Suk; Kabudula, Chodziwadziwa Whiteson; Neilands, Torsten B; Twine, Rhian; Gottert, Ann; Gómez-Olivé, F Xavier; Tollman, Stephen M; Sanne, Ian; Peacock, Dean; Kahn, Kathleen
    Abstract Background HIV transmission can be decreased substantially by reducing the burden of undiagnosed HIV infection and expanding early and consistent use of antiretroviral therapy (ART). Treatment as prevention (TasP) has been proposed as key to ending the HIV epidemic. To activate TasP in high prevalence countries, like South Africa, communities must be motivated to know their status, engage in care, and remain in care. Community mobilization (CM) has the potential to significantly increase uptake testing, linkage to and retention in care by addressing the primary social barriers to engagement with HIV care—including poor understanding of HIV care; fear and stigma associated with infection, clinic attendance and disclosure; lack of social support; and gender norms that deter men from accessing care. Methods/design Using a cluster randomized trial design, we are implementing a 3-year-theory-based CM intervention and comparing gains in HIV testing, linkage, and retention in care among individuals residing in 8 intervention communities to that of individuals residing in 7 control communities. Eligible communities include 15 villages within a health and demographic surveillance site (HDSS) in rural Mpumalanga, South Africa, that were not exposed to previous CM efforts. CM activities conducted in the 8 intervention villages map onto six mobilization domains that comprise the key components for community mobilization around HIV prevention. To evaluate the intervention, we will link a clinic-based electronic clinical tracking system in all area clinics to the HDSS longitudinal census data, thus creating an open, population-based cohort with over 30,000 18–49-year-old residents. We will estimate the marginal effect of the intervention on individual outcomes using generalized estimating equations. In addition, we will evaluate CM processes by conducting baseline and endline surveys among a random sample of 1200 community residents at each time point to monitor intervention exposure and community level change using validated measures of CM. Discussion Given the known importance of community social factors with regard to uptake of testing and HIV care, and the lack of rigorously evaluated community-level interventions effective in improving testing uptake, linkage and retention, the proposed study will yield much needed data to understand the potential of CM to improve the prevention and care cascade. Further, our work in developing a CM framework and domain measures will permit validation of a CM conceptual framework and process, which should prove valuable for community programming in Africa. Trial Registration NCT02197793 Registered July 21, 2014.

    Factors influencing the decision to voluntarily test for HIV: The perceived threats of being HIV positive
    (2009) Lane, Hannah
    This paper investigates voluntary HIV testing behaviour among young adults in two Cape Town townships. Despite exceptionally high HIV prevalence rates, South Africa experiences low rates of HIV testing. Low levels of testing are worrisome because knowledge of HIV status is thought to be a key element in both the prevention of HIV transmission and the provision of care and treatment for those who are infected. Through qualitative in-depth interviews with 15 young adults (9 female, 6 male), this study found that choices regarding the voluntary uptake of HIV testing were strongly linked to the perceived implications of the HIV test. An analysis of the findings illustrates that study participants perceived HIV positive people to experience a number of threats because of their status – namely physical threats, social threats, and psychological threats – and that HIV testing served to either mitigate or expose an individual to these threats. Physical threats posed by HIV, such as opportunistic infections or death, encouraged HIV testing because it was only through testing that these potential threats could be mitigated. Conversely, an HIV test exposed an individual to social threats, such as ostracism and shame, and psychological threats, such as depression and self-rejection. Where social and psychological threats were perceived to be strong, testing was actively avoided. The findings of this study are that the decision to voluntarily test for HIV can be explained through a balance of the physical, social, and psychological threats that one can mitigate or be exposed to through testing for HIV. Using a threat-balance model, the analysis of findings shows that when study participants perceived physical threats to outweigh perceived social and psychological threats of living with HIV, they were biased towards testing. When they viewed social and psychological threats to outweigh physical threats, they were biased against testing. The focus on perceived threats of living with HIV highlights the need to focus on the social and psychological aspects of HIV/AIDS disease and illness, and not simply the clinical diagnosis and treatment of symptoms, both of which focus on physical threats. Because enhanced infrastructural resources for HIV testing and the availability of ARVs for mitigation of the physical threats alone do not encourage HIV testing, a 2 comprehensive plan to increase HIV testing must also seek to reduce the social and psychological threats presented by HIV infection.

    Socio-economic differences in the uptake of HIV testing and associated factors in South Africa
    (2021-08-26) Jooste, Sean; Mabaso, Musawenkosi; Taylor, Myra; North, Alicia; Shean, Yolande; Simbayi, Leickness C.
    Background Improved understanding of barriers to HIV testing is important for reaching the first of the UNAIDS 90–90-90 targets, which states that 90% of HIV positive individuals ought to know their HIV status. This study examined socio-economic status (SES) differences in HIV testing uptake and associated factors among youth and adults 15 years and older in South Africa. Methods This study used data from a national cross-sectional, population-based household survey conducted in 2017 using a multi-stage sampling design. A composite SES score was created using multiple correspondence analyses of household assets; households were classified into wealth quintiles and dichotomised into low SES/poorest (lowest 3 quintiles) and high SES/less-poor (highest 2 quintiles). Bivariate and multivariate logistic regression models were used to examine factors associated with the uptake of HIV testing in low and high SES households. Results HIV testing uptake was 73.8 and 76.7% among low and high SES households, respectively, both of which were below the first 90 targets. Among both low and high SES households, increased HIV testing uptake was significantly associated with females than males. The decreased likelihood was significantly associated with residing in rural formal areas than urban areas, those with no education or low levels of educational attainment and alcohol drinkers among low SES households. Whites and Indians/Asians had a decreased likelihood than Black Africans in high SES households. Conclusions HIV testing interventions should target males, residents in rural formal areas, those with no or low education and those that consume alcohol in low SES households, including Whites and Indians/Asians from high SES households in order to bridge socio-economic disparities in the uptake of HIV testing. This should entail expanding HIV testing beyond traditional centres for voluntary counselling and testing through outreach efforts, including mobile testing and home-based testing.
