Barrier method preferences and perceptions among Zimbabwean women and their partners

Will Men Use Novel Male Contraceptive Methods and Will Women Trust Them? A Systematic Review

Novel male contraceptives have been in development for almost as long as female methods, yet there are no products available on the market. Hormonal approaches tested clinically to date include the use of oral, injectable, implant and transdermal methods. The study of attitudes toward male contraception has been inconsistent and there have been no systematic reviews drawing these data together. We conducted a systematic review of the available evidence for male and female acceptability of novel male contraception. We identified 32 studies and present a narrative synthesis of quantitative data and a thematic synthesis of qualitative data. In novel drug trials, the proportion of male participants willing to use a male contraceptive ranged from 34.0% to as high as 82.3%. In studies regarding hypothetical drugs, male willingness to use ranged from 13.6% to 83.0%. High proportions of women (42.8%-94.0%) reported willingness to use a novel male method in both hypothetical studies and actual drug trials. In qualitative studies, both men and women expressed the desire to share responsibility for contraception. There is consistent interest among both men and women in novel male contraceptive methods and willingness to use them. The systematic review was registered with PROSPERO: CRD42020173281.

Women's sexual experiences as a side effect of contraception in low- and middle-income countries: evidence from a systematic scoping review

Contraception is essential to preventing unintended pregnancy. While contraceptive use has increased significantly over the past decade, discontinuation and gaps in use remain common. Although women cite side effects as the reason for discontinuing or stopping methods, little is known about the specific ways in which contraception affects women's sexual experiences. This systematic scoping review aimed to understand how contraceptive-induced side effects relating to women's sexual experiences have been measured, classified, and explored in the literature, specifically in low- and middle-income countries (LMICs). Studies were eligible for inclusion if they were peer-reviewed, English-language articles published between 2003 and 2018 that examined women's sexual experiences related to their use of modern contraception, including sexual satisfaction, arousal, sexual dysfunction, discomfort, vaginal dryness, sexual frequency, and relationship or partner dynamics. Study populations were restricted to women of reproductive age in LMICs. Twenty-two studies were deemed eligible for inclusion, comprising a range of methods and geographies. Emergent sexual experience themes included: menstrual issues impacting sexual experience; libido; lubrication; sexual pleasure; dyspareunia; and female sexual function. Results highlight the variability in measures used, lack of a women-centred perspective, and void in research outside of high-income countries to study the influence of contraception on women's sexual experiences. Very few studies focused on women's sexual experiences as the primary outcome or predictor. Providers should adopt woman-centred contraceptive counselling that considers women's relationships. Further research is needed to disentangle the nuanced effects of contraception on women's sex lives, contraceptive decision-making, and method continuation.

Understanding the experiences of married Southern African women in protecting themselves from HIV/AIDS: a systematic review and meta-synthesis

Background: Whilst marriage has been repeatedly identified in the literature as an HIV risk factor amongst Southern African women, not much is known about women's perception of their role, experiences and strategies used to address HIV risks in the context of a marriage. Aims: The aim of the study was to synthesise perceptions, experiences and strategies of married Southern African women in the prevention of HIV. Methods: A systematic review of qualitative studies was conducted. Three electronic databases (Medline, Cinahl and PsycINFO) were systematically searched to identify relevant literature. The meta-synthesis process followed Sandelowski and Barroso's [2007. Handbook for Synthesizing Qualitative Research. Springer Publishing Company] recommendations. Results: Of 7 609 papers, 15 were included in the review. The quality of the included studies was variable. In the final synthesis stage, three broad analytic themes emerged: contextual background, cues to preventive behaviour, and HIV prevention strategies. Implications: Findings were used to develop a conceptual framework for studying HIV/AIDS prevention experiences of married Southern African women.

Female condom acceptability in urban India: Examining the role of sexual pleasure

This qualitative study examined the acceptability of female condoms in urban India, with a focus on sexual pleasure. We conducted focus group discussions with 50 women and 19 men, as well as a small number of individual interviews with women ( n = 3), in Chennai and New Delhi. Perceived benefits of female condoms included protection against unintended pregnancy and sexually transmitted infections, increased sense of empowerment for women, and simple clean up. The most common drawback was reduced sensation. Participants suggested structural changes to the female condom to ease insertion and use. Consent and privacy were discussed as increasing sexual pleasure. Pleasure should be acknowledged in design and education efforts to increase female condom use.

Relationships matter: contraceptive choices among HIV-positive women in Tanzania

Efforts to eliminate mother-to-child transmission of HIV in Tanzania are guided by a four-prong strategy advocated by the World Health Organization (WHO). Prong 2, prevention of unintended pregnancies among women living with HIV, has, however, received the least attention and contraceptive use to prevent unintended pregnancies remains low. This study explored the perceived barriers to the use of modern methods of contraception, and factors influencing contraceptive choice among HIV-positive women in urban Dar-es-Salaam, Tanzania. A qualitative multi-site study was conducted, utilising in-depth interviews and focus group discussions with 37 sexually active HIV-positive women aged between 20 and 44 years, attending three health facilities within Dar-es-Salaam. The theoretical framework was a patient centred model. Four barriers were identified: the influence of the women's spousal relationships; personal beliefs and the relationship of these in understanding her disease; the influence of the social demands on the woman and her relationships; and the importance of a woman's relationship with her healthcare provider/healthcare system. Being the bearers of bad news (HIV-positive status) the pregnant women experienced conflicts, violence, abandonment and rejection. The loss in negotiating power for the women was in relation to their intimate partners, but also in the patient-healthcare provider relationship. The role of the male partner as a barrier to contraceptive use cannot be understated. Therefore, the results suggest that healthcare providers should ensure patient-focused education and provide support that encompasses the importance of their relationships. Additional research is required to elucidate the functional association between contraceptive choices and personal and social relationships.

Knowledge, attitudes, practices and behaviors associated with female condoms in developing countries: a scoping review

Women in developing countries are at high risk of HIV, sexually transmitted infections, and unplanned pregnancy. The female condom (FC) is an effective dual protective method regarded as a tool for woman’s empowerment, yet supply and uptake are limited. Numerous individual, socioeconomic, and cultural factors influence uptake of new contraceptive methods. We reviewed studies of FC knowledge, attitudes, practices, and behaviors across developing countries, as well as available country-level survey data, in order to identify overarching trends and themes. High acceptability was documented in studies conducted in diverse settings among male and female FC users, with FCs frequently compared favorably to male condoms. Furthermore, FC introduction has been shown to increase the proportion of “protected” sex acts in study populations, by offering couples additional choice. However, available national survey data showed low uptake with no strong association with method awareness, as well as inconsistent patterns of use between countries. We identified a large number of method attributes and contextual factors influencing FC use/nonuse, most of which were perceived both positively and negatively by different groups and between settings. Male partner objection was the most pervasive factor preventing initial and continued use. Importantly, most problems could be overcome with practice and adequate support. These findings demonstrate the importance of accounting for contextual factors impacting demand in FC programming at a local level. Ongoing access to counseling for initial FC users and adopters is likely to play a critical role in successful introduction.

Assessing base rates of sexual behavior using the unmatched count technique

Estimating the prevalence of sexual behaviors is difficult because of self-report biases. This is particularly relevant in assessing high-risk sexual behaviors for the purpose of reducing the transmission and acquisition of sexually transmitted infections (STIs) and HIV/AIDS. The present study employed the unmatched count technique (UCT), which provides estimates of the prevalence of risky sexual behaviors without requiring participants to confess to socially undesirable or stigmatized behaviors. Compared to a standard, anonymous self-report questionnaire, the UCT protocol revealed that people were less likely to notify their partners about STIs or discuss their history of sexual experiences. Effects were particularly large in women suggesting that women may be more likely to misrepresent their sexual behaviors. The findings suggest that conventional, anonymous self-report questionnaire data of base rates of risky sexual behavior and sexual communication are consistently inaccurate. These discrepant base rates suggest that the UCT might provide a better estimate of the frequency of these behaviors. Results suggest that inconsistent sexual behavior is more rampant than anonymous questionnaires suggest. They also underscore the need for improvements in the anonymity of assessment of sexual behaviors, which could in turn improve the targeting of prevention efforts. Results have important public health implications because accurate assessment of sexual behaviors is crucial for developing effective STI prevention interventions among target populations.

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.

A qualitative study of obstacles to diaphragm and condom use in an HIV prevention trial in sub-Saharan Africa

Consistent condom use and the substitution of condoms with potential HIV prevention methods of lower or unknown effectiveness are important concerns in the development of new prevention technologies. This qualitative study explored obstacles to consistent condom use with the diaphragm in MIRA, an HIV prevention trial in South Africa and Zimbabwe. We conducted 26 focus group discussions (FGDs) with 206 women and 7 FGDs and 10 in-depth interviews with 41 male partners of intervention-arm women. The belief that the diaphragm/gel prevented HIV, women's difficulties negotiating condom use, and men's unawareness that using the products together was recommended were obstacles to consistent condom use with the diaphragm/gel. Concerns about protection from HIV and pregnancy, recognition that the diaphragm was not yet proven to prevent HIV or sexually transmitted infections, and the trial context were facilitators. Understanding selective study product use in HIV prevention trials may inform improved adherence counseling and male involvement strategies.

User experiences and acceptability attributes of the diaphragm and lubricant gel in an HIV prevention trial in southern Africa

Methods for Improving Reproductive Health in Africa (MIRA), a phase III HIV prevention trial, was conducted among 5039 Zimbabwean and South African women to test the Ortho All-Flex diaphragm and Replens(®) lubricant gel. Among the 2418 intervention group participants, 105 women who had completed the trial and 41 male partners participated in focus group discussions and in-depth interviews about the acceptability of the diaphragm and gel and their experiences using the study products. Women who participated in the qualitative study had exited the trial in the prior nine months, were HIV negative, and used the diaphragm and gel for 12-24 months. The comprehensive and flexible conceptual framework was applied to investigate the salient attributes for acceptability of the products as potential HIV prevention methods, and emerging themes for acceptability were framed within three categories of attributes (product, relationship, and sexual intercourse attributes). Both diaphragm and gel were found to be highly acceptable in the study group, and the gel was popular due to its effect of enhancing sexual pleasure. Some of the important product attributes influencing acceptability as reported by users were convenience, ease of use, dual use potential for contraception and disease prevention, and being female-initiated. It was also noted that some elements (such as sexual pleasure, couple communication, and the necessity of diaphragm negotiation) could be more important than others in terms of influencing product acceptability and use. Acceptability attributes reflective of the broader contextual environment (beliefs generated in the trial community suggesting preventive efficacy - preventive method optimism - and gendered norms favoring male superiority in sexual decision making) also emerged as important themes. The high level of acceptability of the diaphragm and gel among MIRA trial participants and their male partners is an indicator of the continued need for an effective female-initiated product.

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.

Acceptability of contraception for men: a review

Methods of contraception for use by men include condoms, withdrawal and vasectomy. Prevalence of use of a method and continuation rates are indirect measures of acceptability. Worldwide, none of these "male methods" accounts for more than 7% of contraceptive use although uptake varies considerably between countries. Acceptability can be assessed directly by asking about intended (hypothetical) use and assessing satisfaction during/after use. Since they have been around for a very long time, there are very few data of this nature on condoms (as contraceptives rather than for prevention of infection), withdrawal or vasectomy. There are direct data on the acceptability of hormonal methods for men but from relatively small clinical trials which undoubtedly do not represent the real world. Surveys undertaken among the male general public demonstrate that, whatever the setting, at least 25% of men - and in most countries substantially more - would consider using hormonal contraception. Although probably an overestimate of the number of potential users when such a method becomes available, it would appear that hormonal contraceptives for men may have an important place on the contraceptive menu. Despite commonly expressed views to the contrary, most women would trust their male partner to use a hormonal method.

Adherence to diaphragm use for infection prevention: a prospective study of female sex workers in Kenya

Objective. To assess adherence to and acceptability of the diaphragm among 140 female sex workers in Kenya in a 6-month prospective study. Methods. At baseline and bimonthly visits, participants were interviewed on diaphragm knowledge, attitude, and practices. We used principal component analysis and logistic regression to identify predictors of consistent use. Results. At 50% of 386 bimonthly visits, women reported consistently using a diaphragm with all partners during the preceding 2 weeks. Consistent use was significantly higher at the 6-month than the 2-month visit. Women reported less covert use with “helping” (regular sex partners to whom she could go for help or support) than with “other” partners. Perceptions that diaphragms are easier to use than condoms and that their lack of coital interruption is important were associated with consistent diaphragm use with both partner types. Partner support of diaphragm use is correlated with consistent use with “helping” partners only while higher parity, consistent condom use, and perceived lack of need of condoms as a benefit of diaphragms were associated with consistent use with “other” partners. Conclusions. Diaphragm acceptance among female sex workers in Nairobi was high. Future studies should distinguish between partner types when evaluating diaphragm adherence.

Wear and care of the SILCS diaphragm: experience from three countries

Background: Women have been regularly underestimated in their ability to care for and wear cervical barrier devices such as diaphragms appropriately. Methods: Data from two non-randomised, non-blinded, non-significant risk acceptability studies of a novel cervical barrier device, the SILCS diaphragm, conducted in the Dominican Republic (n = 20), South Africa (n = 21) and Thailand (n = 20), are used to provide insights into the fundamental question of how women actually use an intravaginal device within the constraints of low-resource settings. In all sites, couples not at risk of pregnancy and at low risk of sexually transmissible infections used the SILCS diaphragm four times and provided feedback on acceptability, care and use of the device via product use questionnaires and gender-specific debriefing interviews. Results: Data from user acceptability studies in these three countries provide an intimate view of how women care for and store the SILCS diaphragm, and both female and male perceptions about handling and re-using it. Results support the view that women are able to wear and care for diaphragms successfully in a variety of settings. In general, male partners were also supportive of care and reuse of the diaphragm. Conclusions: While the results from these studies indicate that women are able to find ways to cope successfully with the logistics of wearing and caring for an intravaginal device, further supportive evidence from a woman-centred perspective is crucial for reproductive health policymakers and program managers. The authors contend that it is time to reassess perceived constraints to barrier protection.

Degrees of disclosure: a study of women's covert use of the diaphragm in an HIV prevention trial in sub-Saharan Africa

In sub-Saharan Africa more women are infected with HIV/AIDS than men and new prevention methods are urgently needed. One major attribute of female-initiated HIV prevention methods is that they can be used covertly, without a male partner's knowledge. Using mixed methods, we explored the predictors and dimensions of covert use of the diaphragm in a randomized controlled trial that tested its effectiveness for HIV prevention. The Methods for Improving Reproductive Health in Africa (MIRA) trial was conducted in Zimbabwe and South Africa, and data collection took place between September 2003 and January 2007. This study is a secondary analysis of quantitative and qualitative data from participants randomized to the intervention group, and their male partners. It includes survey data from 2316 women (mean age=28.3), 14 focus group discussions (FGD) conducted with 104 women, and 7 FGD and 10 in-depth interviews with 37 male partners. The median follow-up for trial participation was 21 months (range: 12-24). At their final visit, approximately 9% of women had never disclosed to their primary partners that they were using the diaphragm (covert use). In multivariate analysis, predictors of covert use included being older, not co-habiting with the partner, having a partner who did not use condoms, and being from South Africa. Qualitative analysis revealed that covert use was not dichotomous, but ranged along a continuum, which we categorized into five levels (i.e. full disclosure; mostly open use; occasional covert use; mostly covert use; and completely covert use). We discuss the critical role of the option of covert use for many women in the context of an HIV prevention trial, as well as gender power dynamics which may influence women's decisions about disclosure.

The use of the diaphragm instead of condoms in a phase III diaphragm trial

The MIRA trial assessed whether providing diaphragm, lubricant gel, and condoms (intervention) compared with condoms alone (control) could reduce HIV incidence among 5,039 Southern African women. Compared with the control group, the cumulative proportion of last sex acts protected by any method was higher in the intervention group (OR = 1.33; 95% CI 1.18, 1.49); however, only 36.3% of last sex acts were protected by both a male condom and a diaphragm, whereas 36.6% were protected by a diaphragm only. Product substitution (ever deciding to use a diaphragm instead of a condom in the previous 3 months) was reported at every visit by 22.4%, at some visits by 60.7%, and at none of the visits by 16.8% of these women. Women at greater risk for infection through their own or their partner's behavior or who believed the diaphragm protected against HIV were more likely to report product substitution at every visit.

Biomedical interventions to prevent HIV infection: evidence, challenges, and way forward

Intensive research efforts for more than two decades have not yet resulted in an HIV vaccine of even moderate effectiveness. However, some progress has been made with other biomedical interventions, albeit on the basis of inconsistent levels of evidence. The male condom, if used correctly and consistently, has been proven in observational studies to be very effective in blocking HIV transmission during sexual intercourse; and, in three randomised trials, male circumcision was protective against HIV acquisition among men. Treatment of sexually transmitted infections, a public health intervention in its own right, has had mixed results, depending in part on the epidemic context in which the approach was assessed. Finally, oral and topical antiretroviral compounds are being assessed for their role in reduction of HIV transmission during sexual intercourse. Research on biomedical interventions poses formidable challenges. Difficulties with product adherence and the possibility of sexual disinhibition are important concerns. Biomedical interventions will need to be part of an integrative package that includes biomedical, behavioural, and structural interventions. Assessment of such multicomponent approaches with moderate effects is difficult. Issues to be considered include the nature of control groups and the effect of adherence on the true effectiveness of the intervention.

Pleasure, power, and inequality: incorporating sexuality into research on contraceptive use

We know surprisingly little about how contraception affects sexual enjoyment and functioning (and vice versa), particularly for women. What do people seek from sex, and how do sexual experiences shape contraceptive use? We draw on qualitative data to make 3 points. First, pleasure varies. Both women and men reported multiple aspects of enjoyment, of which physical pleasure was only one. Second, pleasure matters. Clear links exist between the forms of pleasure respondents seek and their contraceptive practices. Third, pleasure intersects with power and social inequality. Both gender and social class shape sexual preferences and contraceptive use patterns. These findings call for a reframing of behavioral models that explain why people use (or do not use) contraception.

Female condom uptake and acceptability in Zimbabwe

As the first phase of a two-phase prospective cohort study to assess the acceptability of the diaphragm as a potential HIV/STI prevention method, we conducted a 2-month prospective study and examined the effect of a male and female condom intervention on female condom (FC) use among 379 sexually active women in Harare, Zimbabwe. Reported use of FC increased from 1.1% at baseline to 70.6% at 2-month follow-up. Predictors of FC uptake immediately following the intervention included interest in using FC, liking FC better than male condoms, and believing one could use them more consistently than male condoms. Women reported 28.8% of sex acts protected by FC in the 2 weeks prior to last study visit. Though FC may not be the preferred method for the majority of women, with access, proper education, and promotion they may be a valuable option for some Zimbabwean women.

Women in the time of AIDS: barriers, bargains, and benefits

We comment here on the implications of new HIV prevention technologies (physical and chemical barriers) for women's health and women's rights. Four relevant themes are selected that have emerged in the social and behavioral science literature: structural factors (global and national) limiting the availability of female condoms, control and empowerment with female-initiated HIV prevention technologies, covert use of female-initiated HIV prevention technologies, and male partners as part of the bargain for barriers. There is now a rich and diverse literature on all of these issues, relevant and informative (much is addressed in this issue), which we draw together in this commentary. Discussion of these themes suggests guidelines for policy, research, and action. First, the misconceptions, biases, and prejudices of global and national leaders, including donors, necessitate that we persevere in presenting data to them and engaging them in discussion. Second, we need to support women within their local social contexts to negotiate for their rights, balancing pragmatic approaches to their partners in their initiation of protection, and applying according to each situation as appropriate, a continuum from discretion and clandestine use to deception. Third, men have to be brought in as active participants, and their positive and negative experiences and interests inserted into practices and policies.

Diaphragm and lubricant gel for prevention of HIV acquisition in southern African women: a randomised controlled trial

BACKGROUND

Female-controlled methods of HIV prevention are urgently needed. We assessed the effect of provision of latex diaphragm, lubricant gel, and condoms (intervention), compared with condoms alone (control) on HIV seroincidence in women in South Africa and Zimbabwe.

METHODS

We did an open-label, randomised controlled trial in HIV-negative, sexually active women recruited from clinics and community-based organisations, who were followed up quarterly for 12-24 months (median 21 months). All participants received an HIV prevention package consisting of pre-test and post-test counselling about HIV and sexually transmitted infections, testing, treatment of curable sexually transmitted infections, and intensive risk-reduction counselling. The primary outcome was incident HIV infection. This study is registered with ClinicalTrials.gov, number NCT00121459.

FINDINGS

Overall HIV incidence was 4.0% per 100 woman-years: 4.1% in the intervention group (n=2472) and 3.9% in the control group (n=2476), corresponding to a relative hazard of 1.05 (95% CI 0.84-1.32, intention-to-treat analysis). The proportion of women using condoms was significantly lower in the intervention than in the control group (54%vs 85% of visits, p<0.0001). The proportions of participants who reported adverse events (60% [1523] vs 61% [1529]) and serious adverse events (5% [130] vs 4% [101]) were similar between the two groups.

INTERPRETATION

We observed no added protective benefit against HIV infection when the diaphragm and lubricant gel were provided in addition to condoms and a comprehensive HIV prevention package. Our observation that lower condom use in women provided with diaphragms did not result in increased infection merits further research. Although the intervention seemed safe, our findings do not support addition of the diaphragm to current HIV prevention strategies.

The importance of discreet use of the diaphragm to Zimbabwean women and their partners

We conducted a 6-month acceptability study of diaphragms as a potential HIV/STI prevention method among Zimbabwean women. We examined partner involvement in diaphragm use, and importance of discreet use (use without partner awareness). Of the 181 women who completed the study, 45% said discreet use was "very or extremely important" and in multivariate logistic regression, women were more likely to value discretion if their partners: had other partners; drank alcohol; or were believed to prefer condoms to diaphragms. Qualitative data confirmed these findings. Both women and their partners reported that diaphragms can be used discreetly and saw this as advantageous, for both sexual pleasure and female control. However, many were concerned that use without partner approval could lead to marital problems. Discreet use should be considered in development of barrier methods and in diaphragm promotion, if proven effective against HIV/STI.

Introducing diaphragms into the mix: what happens to male condom use patterns?

The objective of this analysis was to assess the effect of introducing the diaphragm on condom use patterns. Participants included one hundred eighty-nine women attending family planning clinics in Harare, Zimbabwe who reported less than 100% condom use. The proportion of acts where at least one method was used significantly increased over using follow-up; male condom use remained stable. A diaphragm was used with 50% to 54% of acts; male condoms were also used about 50% of the time. The proportion of acts where a female condom was used decreased. Women who used both male and female condoms were more likely to use diaphragms than those who reported not using female condoms. Introducing the diaphragm increased the overall proportion of protected acts. The proportion of acts where a male condom was used did not change. Female condoms use declined because concurrent use with the diaphragm is not possible.
