BackgroundIn VOICE, a multisite HIV pre-exposure prophylaxis (PrEP) trial, plasma drug levels pointed to widespread product nonuse, despite high adherence estimated by self-reports and clinic product counts. Using a socio-ecological framework (SEF), we explored socio-cultural and contextual factors that influenced participants’ experience of daily vaginal gel and oral tablet regimens in VOICE.MethodsIn Johannesburg, a qualitative ancillary study was concurrently conducted among randomly selected VOICE participants assigned to in-depth interviews (n = 41), serial ethnographic interviews (n = 21), or focus group discussions (n = 40). Audiotaped interviews were transcribed, translated, and coded thematically for analysis.ResultsOf the 102 participants, the mean age was 27 years, and 96% had a primary sex partner with whom 43% cohabitated. Few women reported lasting nonuse, which they typically attributed to missed visits, lack of product replenishments, and family-related travel or work. Women acknowledged occasionally skipping or mistiming doses because they forgot, were busy, felt lazy or bored, feared or experienced side effects. However, nearly all knew or heard of other study participants who did not use products daily. Three overarching themes emerged from further analyses: ambivalence toward research, preserving a healthy status, and managing social relationships. These themes highlighted the profound and complex meanings associated with participating in a blinded HIV PrEP trial and taking antiretroviral-based products. The unknown efficacy of products, their connection with HIV infection, challenges with daily regimen given social risks, lack of support–from partners and significant others–and the relationship tradeoffs entailed by using the products appear to discourage adequate product use.ConclusionsPersonal acknowledgment of product nonuse was challenging. This qualitative inquiry highlighted key influences at all SEF levels that shaped women’s perceptions of trial participation and experiences with investigational products. Whether these impacted women’s behaviors and may have contributed to ineffective trial results warrants further investigation.

Microbicides are most usually conceptualised within a disease prevention framework and studies usually define acceptability in terms of product characteristics, willingness to use and risk reduction. This starting point has led to assumptions about microbicides which, rather than being challenged by empirical studies, have tended to foreclose the data and subsequent conceptual models. Few studies take an emic ('insider') perspective or attempt to understand how microbicides fit into the broader context of women's and men's everyday lives. As part of the integrated social science component of the MDP301 Phase III microbicide trial, in-depth interviews were conducted with female trial participants in South Africa, Zambia, Tanzania and Uganda. Women's experiences of the gel challenge several assumptions that have commonly been reiterated about microbicides. Our analysis suggests that current definitions and conceptual frameworks do not adequately account for the range of meanings that women attribute to gel. Even within the context of a clinical trial, it is possible to obtain a richer, ethnographic and cross-cultural concept of acceptability based on women's practice and emic interpretations. We now need to move beyond limited notions of acceptability and consider how microbicides fit into a more holistic picture of women's and men's sexuality and sexual health.

Little is known about how menstruation is managed in low-income settings and whether existing sanitation systems meet women's needs. Using the 'Photovoice' method with 21 women in participatory workshops and in-depth interviews, we collected data on menstrual hygiene management in three sites in Durban, South Africa. All women reported using disposable sanitary pads. Although they were aware that disposable pads were nonbiodegradable, incompatible with waterborne flush systems, and fill up pit latrines, they had little experience with reusable products. Considerable energy was devoted to concealing and containing 'menstrual waste,' and women expressed concern about inadequate privacy during menstruation. All sites lacked discreet disposal options and reliable water access, while outdoor sanitation facilities were considered unsafe. Findings highlight the need for advocacy to improve safety and privacy of facilities for women in this setting.
