What Have We Learned? Implementation of a Shared Learning Agenda and Access Strategy for the Hormonal Intrauterine Device.

In 2015, a global learning agenda for the hormonal intrauterine device (IUD) was developed with priority research questions regarding use of the method in low- and middle-income countries. In addition, members of the Hormonal IUD Access Group aligned on a strategy to expand access in the context of volunteerism and contraceptive method choice. This article synthesizes evidence generated since then and describes steps taken to address demand- and supply-side barriers to access. Findings demonstrated high continuation rates and satisfaction among hormonal IUD users that are comparable to other long-acting reversible contraceptives (LARCs). Across studies, a sizable number of users reported they would have chosen a short-acting method or no method at all if the hormonal IUD were not an option, which suggests that women did not see the hormonal IUD as interchangeable with other LARC options and thus it may fill an important niche in the market. With several countries now poised to scale up the method, resource mobilization will be key. On the demand side, investments in implementation research will be critical to understanding how best to launch and scale the method, while ensuring the sustainability of multiple quality-assured suppliers with affordable public-sector pricing will be necessary on the supply side.

Sharing the trousers: gender roles and relationships in an HIV-prevention trial in Zimbabwe.

Male and female gender roles and inequalities are important in contributing to the disproportionate burden of HIV experienced by women in sub-Saharan Africa. Within the context of an HIV prevention trial, we aimed to describe and understand male partner influence on women's use of HIV-prevention methods. Our presumption was not that regressive gender norms prevailed - rather, that a wide range of gendered attitudes and dynamics would be expressed among couples. Data from 16 focus groups with Zimbabwean female trial participants and their male partners and 4 in-depth couples interviews were collected, and form the basis of the analysis. Findings offer descriptions of how couples have adapted techniques for negotiating modern household economies and sexual decision-making in a manner that both preserves traditional gender roles, while accommodating women's entrance into new domains such as the workforce or an HIV-prevention trial. Women's agency to introduce novel female-initiated-method use into her intimate relationships is described. Men and women's accounts of method introduction and use suggest different perceptions about the locus of sexual decision making. The study provides unique insight into a gendered context that is dynamic yet sensitive to change, which in turn can provide useful information to more appropriately guide HIV-prevention activities in this setting.

The importance of male partner involvement for women's acceptability and adherence to female-initiated HIV prevention methods in Zimbabwe.

Enlisting male partner involvement is perceived as an important component of women's successful uptake of female-initiated HIV prevention methods. We conducted a longitudinal study among a cohort of 955 Zimbabwean women participating in a clinical trial of the effectiveness of a female-initiated HIV prevention method (the diaphragm and lubricant gel) to: (a) describe the extent to which women involved their male partners in the decision to use the study products, and (b) measure the effect perceived male partner support had on their acceptability and consistent use of these methods. Reported levels of male partner involvement in discussions and decisions regarding: joining the study, study activities, the outcome of HIV/STI test results, and product use were very high. In multivariate analyses, regular disclosure of study product use and partner approval for the diaphragm and gel were significantly associated with women's acceptability and consistent use of the products; an essential component for determining efficacy of investigational prevention methods. These results support the need for more sophisticated measurement of how couples interact to make decisions that impact study participation and investigational product use as well as more rigorous adaptations and evaluations of existing strategies to involve male partners in female-initiated HIV prevention trials.

Vaginal practices and associations with barrier methods and gel use among Sub-Saharan African women enrolled in an HIV prevention trial.

Vaginal practices may interfere with the use and/or the effectiveness of female-initiated prevention methods. We investigated whether vaginal practices differed by randomization group in a phase III trial of the diaphragm with lubricant gel (MIRA) in Sub-Saharan Africa (n = 4925), and if they were associated with consistent use of study methods. At baseline, vaginal practices were commonly reported: vaginal washing (82.77%), wiping (56.47%) and insertion of dry or absorbent materials (20.58%). All three practices decreased during the trial. However, women in the intervention group were significantly more likely to report washing or wiping during follow-up compared to those in the control group. Additionally, washing, wiping, and insertion, were all independently and inversely associated with consistent diaphragm and gel use and with condom use as well, regardless of study arm. A better understanding of the socio-cultural context in which these practices are embedded could improve educational strategies to address these potentially modifiable behaviors, and may benefit future HIV prevention interventions of vaginal methods.

Acceptability and use of the diaphragm and Replens lubricant gel for HIV prevention in Southern Africa.

The acceptability and use of the diaphragm and lubricant gel were assessed as part of a large randomized controlled trial to determine the effectiveness of the methods in women's HIV acquisition. 2,452 intervention-arm women were enrolled at five Southern African clinics and followed quarterly for 12-24 months. Acceptability and use data were collected by face-to-face interviews at Month 3 and Exit. Participants were "very comfortable" with the physical mechanics of diaphragm use throughout the trial, and approval of the gel consistency, quantity and the applicator was high. At Exit, consistent disclosure of use (AOR 1.97, 95% CI: 1.10-3.55); an overall high diaphragm rating (AOR 1.84, 95% CI: 1.45-2.34) and perception of partner approval (AOR 1.75, 95% CI: 1.35-2.26) were the most significant acceptability factors independently associated with consistent use. Despite being female-initiated, disclosure of use to male partners and his perceived approval of the products were factors significantly associated with their consistent use.

Novel strategies implemented to ensure high participant retention rates in a community based HIV prevention effectiveness trial in South Africa and Zimbabwe.

BACKGROUND: The identification of new HIV prevention methods that women can initiate themselves are urgently needed, particularly in high prevalence settings. HIV prevention trials must be designed with large sample sizes and/or substantial follow-up periods to ensure enough statistical power to measure product effectiveness. This paper describes the attendance rates of the Methods for Improving Reproductive Health in Africa (MIRA) trial, reasons for missed visits, and strategies used to retain participants; and examines demographic and behavioural predictors of retaining women. METHODS: HIV negative, sexually active females were enrolled into the MIRA trial in Zimbabwe and South Africa. Once enrolled, women were expected to visit the clinic at 2 weeks and quarterly thereafter for 12 to 24 months. Tabulations of visit-specific retention rates are presented, along with a descriptive summary of retention strategies established prior to and in response to challenges incurred during implementation. Both univariate and multivariate logistic regression models were created in STATA to examine predictors of being retained vs. lost-to-follow-up. RESULTS: At the three sites, the final retention rates were 94%, 93% and 89% for Zimbabwe, Durban and Johannesburg, respectively. This was achievable through intensive outreach efforts toward the latter part of the trial and a commitment from all staff. Each site implemented several retention strategies. CONCLUSION: The high retention rates were achievable in this trial through added staff efforts and resources. Community involvement was also crucial to achieve these rates. Retention of trial participants should be considered during trial design and implemented from the onset.

Patterns and predictors of adherence to diaphragm use in a phase III trial in sub-Saharan Africa: a trajectory analysis.

BACKGROUND: We examined diaphragm adherence among 2429 women randomized to the intervention arm (diaphragm + gel + condoms) in Methods for Improving Reproductive Health in Africa, a phase III trial of the diaphragm for HIV prevention in Zimbabwe and South Africa. METHODS: Women were followed for a median of 7 quarterly visits (range: 1-8 quarterly visits) during which diaphragm adherence was assessed. We conducted trajectory analyses to identify behavioral groups associated with specific diaphragm adherence patterns. Multivariate multinomial logistic regression was used to identify baseline characteristics associated with higher probability of being in a particular trajectory group. RESULTS: Diaphragm uptake was very high (3.1% never used diaphragms). However, diaphragm adherence was reported at only 49% of visits. Women were clustered into 4 diaphragm adherence groups based on their highest estimated group membership probability: low adherers (31.0%), decreasing adherers (28.9%), increasing adherers (9.3%), and high adherers (30.8%). Women classified as high adherers (as compared with low adherers) were more likely to be older [adjusted odds ratio (AOR) = 1.09, 95% confidence interval (CI): 1.07 to 1.11] and to report baseline condom adherence (AOR = 2.00, 95% CI: 1.47 to 2.71). They were less likely to have high-risk behavior (AOR = 0.51; 95% CI: 0.37 to 0.71) and to have high-risk partners (AOR = 0.58; 95% CI: 0.43 to 0.78). They were most likely to be from the Zimbabwe site (AOR = 2.82; 95% CI: 1.89 to 4.20) and least likely to be from the Johannesburg site (AOR = 0.51; 95% CI: 0.37 to 0.77). CONCLUSION: This analytic approach could help to identify high compliers for enrollment in future HIV prevention trials or the types of participants who may need intensive adherence counseling during follow-up.
