Use-effectiveness of the female versus male condom in preventing sexually transmitted disease in women

Adding the female condom to the public health agenda on prevention of HIV and other sexually transmitted infections among men and women during anal intercourse

Legal barriers to conducting public health research on methods of protection for anal intercourse were lifted in the United States in 2003 when the US Supreme Court invalidated all state antisodomy laws. Although research funding has been available for the development of rectal microbicides, the female condom, which has already been approved for vaginal use, has not been evaluated for anal use. Although there is no evidence that the female condom is safe for anal intercourse, it has already been taken up for off-label use by some men who have sex with men. This demonstrates the urgent need for more protection options for anal intercourse and, more immediately, the need to evaluate the safety and efficacy of the female condom for anal intercourse.

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.

Prostate-specific antigen in vaginal fluid after exposure to known amounts of semen and after condom use: comparison of self-collected and nurse-collected samples

BACKGROUND

Prostate-specific antigen (PSA) in vaginal fluid indicates exposure to semen, and was used to assess condom effectiveness, although validity and reliability have not been fully evaluated. Our objective was to compare PSA in self-collected samples with samples collected by a nurse.

METHODS

We conducted two studies, each with 100 women aged 18-48 years. In the first, a nurse exposed each participant to her partner's semen (10, 100 and 1000 microl), and nurse and participant collected samples. In the second, each participant sampled before and after using two male condoms (MC) and two female condoms (FC); a nurse collected another sample afterwards.

RESULTS

PSA concentration increased with semen exposure, but was lower in nurse-collected samples. Both procedures were sensitive, almost 100% after exposure to 100-1000 microl of semen. PSA detection rates with MC and FC were 13% and 28% in self-collected samples, 8% and 9% in nurse-collected samples. Concordance between sample types was 93% with the MC (95% CI: 89%; 96%), 78% with the FC (95% CI: 72%; 84%). PSA decay between sampling times may explain higher values in self-collected samples.

CONCLUSIONS

PSA is a highly sensitive surrogate endpoint for condom effectiveness studies. Self-collected and nurse-collected samples are equivalent, but sample collection timing is critical.

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.

Prevention of infectious diseases in athletes

The sports medicine physician may face challenging issues regarding infectious diseases when dealing with teams or highly competitive athletes who have difficulties taking time off to recover. One must treat the individual sick athlete and take the necessary precautions to contain the spread of communicable disease to the surrounding team, staff, relatives, and other contacts. This article reviews preventive strategies for infectious disease in athletes, including immunization recommendations and prophylaxis guidelines, improvements in personal hygiene and prevention of spread of infectious organisms by direct contact, insect-borne disease precautions, and prevention of sexually transmitted diseases. A special emphasis on immunizations focuses on pertussis, influenza, and meningococcal prophylaxis.

Randomised controlled trial of alternative male and female condom promotion strategies targeting sex workers in Madagascar

OBJECTIVES

To assess whether individual clinic-based counselling as a supplement to peer education for male and female condom promotion leads to greater use of protection and lower STI prevalence among sex workers in Madagascar already exposed to intensive male condom promotion.

METHODS

In two public dispensaries in Madagascar, a total of 901 sex workers were randomly allocated between two alternative male and female condom promotion

INTERVENTIONS

peer education only, or peer education supplemented with individual clinic-based counselling. Participants were followed for 12 months. Every 2 months they made clinic visits, where they were interviewed on condom use. Peer educators counselled all participants on condom use as they accompanied their assigned participants to study visits. Participants assigned to receive the supplemental intervention were counselled by a trained clinician following study interviews. Participants were tested and treated for chlamydia, gonorrhoea and trichomoniasis every 6 months. We used logistic regression to assess whether the more intensive intervention was associated with reduced STI prevalence. Use of protection with clients and non-paying partners was assessed by study arm, site, and visit.

RESULTS

There was no statistically significant association between study arm and aggregated STI prevalence. No substantial differences in levels of reported protection were noted between study groups.

CONCLUSIONS

This study found little evidence for gains from more thorough clinical counselling on male and female condom use. These findings suggest that less clinically intensive interventions such as peer education could be suitable for male and female condom promotion in populations already exposed to barrier method promotion.

Reproductive Choice for Women and Men Living with HIV: Contraception, Abortion and Fertility

From a policy and programmatic point of view, this paper reviews the literature on the fertility-related needs of women and men living with HIV and how the entry points represented by family planning, sexually transmitted infection and HIV-related services can ensure access to contraception, abortion and fertility services for women and men living with HIV. Most contraceptive methods are safe and effective for HIV positive women and men. The existing range of contraceptive options should be available to people living with HIV, along with more information about and access to emergency contraception. Potential drug interaction must be considered between hormonal contraception and treatment for tuberculosis and certain antiretroviral drugs. Couples living with HIV who wish to use a permanent contraceptive method should have access to female sterilisation and vasectomy in an informed manner, free of coercion. How to promote condoms and dual protection and how to make them acceptable in long term-relationships remains a challenge. Both surgical and medical abortion are safe for women living with HIV. To reduce risk of vertical transmission of HIV and in cases of infertility, people with HIV should have access to sperm washing and other assisted conception methods, if these are available. Simple and cost-effective procedures to reduce risk of vertical transmission should be part of counselling for women and men living with HIV who intend to have children. Support for the reproductive rights of people with HIV is a priority. More operations research on best practices is needed.

Country-wide distribution of the nitrile female condom (FC2) in Brazil and South Africa: a cost-effectiveness analysis

OBJECTIVE

To evaluate the cost-effectiveness and potential impact of expanded female condom distribution.

DESIGN

Cost-effectiveness analysis assessing HIV infections averted annually and incremental cost per HIV infection averted for country-wide distribution of the nitrile female condom (FC2) among sexually active individuals, 15-49 years, with access to publicly distributed condoms in Brazil and South Africa.

RESULTS

In Brazil, expansion of FC2 distribution to 10% of current male condom use would avert an estimated 604 (5-95th percentiles, 412-831) HIV infections at 20,683 US dollars (5-95th percentiles, 13,497-29,521) per infection averted. In South Africa, 9577 (5-95th percentiles, 6539-13,270) infections could be averted, at 985 US dollars (5-95th percentiles, 633-1412) per infection averted. The estimated cost of treating one HIV-infected individual is 21,970 US dollars (5-95th percentiles, 18,369-25,719) in Brazil and 1503 US dollars (5-95th percentiles, 1245-1769) in South Africa, indicating potential cost savings. The incremental cost of expanded distribution would be reduced to 8930 US dollars (5-95th percentiles, 5864-13,163) per infection averted in Brazil and 374 US dollars (5-95th percentiles, 237-553) in South Africa by acquiring FC2s through a global purchasing mechanism and increasing distribution threefold. Sensitivity analyses show model estimates to be most sensitive to the estimated prevalence of sexually transmitted infections, total sexual activity, and fraction of FC2s properly used.

CONCLUSIONS

Expanded distribution of FC2 in Brazil and South Africa could avert substantial numbers of HIV infections at little or no net cost to donor or government agencies. FC2 may be a useful and cost-effective supplement to the male condom for preventing HIV.

The promises and limitations of female-initiated methods of HIV/STI protection

New methods are now available, and others are being developed, that could enable women to take the initiative in preventing sexually transmitted infections. However, attempts to capitalize on "female-controlled" preventive methods thus far have met with limited success. Female-initiated methods were introduced to intervene in the state of gender relations and assist women who are disempowered vis-à-vis their male partners. Paradoxically, however, we underscore that it is the very structure of regional and local gender relations that shapes the acceptability (or lack of acceptability) of these methods. This paper specifically addresses how the structure of gender relations-for better and for worse-shapes the promises and limitations of widespread use and acceptance of female-initiated methods. We draw on examples from around the world to underscore how the regional specificities of gender (in)equality shape the acceptance, negotiation, and use of these methods. Simultaneously, we demonstrate how the introduction and sustained use of methods are shaped by gender relations and offer possibilities for reinforcing or challenging their current state. Based on our analyses, we offer key policy and programmatic recommendations to increase promotion and effective use of women-initiated HIV/STI protection methods for both women and men.

Long-term female condom use among vulnerable populations in Brazil

We carried out an evaluative study on factors associated with long-term use of female condoms for STI/HIV prevention. A total of 255 women and 29 men who were using female condoms for at least 4 months participated in qualitative/quantitative interviews. The study was conducted in six Brazilian cities. Four primary themes were identified as influencing acceptability and adoption of the female condom: (1) personal "assistance" (counseling) during the early adoption phase; (2) safety; (3) pleasure; and (4) increased sense of power for safer sex negotiation. Alternate use of male and female condoms was the norm among participants, but for approximately one third of the sample, the female condom was the preferred option for safer sex. The study findings suggest that providing clients with explicit and sustained intervention strategies may have a decisive influence on long-term adoption of female condoms.

Does a choice of condoms impact sexually transmitted infection incidence? A randomized, controlled trial

OBJECTIVE

The objective of this study was to assess whether providing a choice of condoms would increase condom acceptability, increase self-reported use, and decrease incident sexually transmitted infection.

STUDY

We randomized 414 men presenting with urethral discharge in Jamaica to receive either the "standard" clinic condom or a choice of 4 different types of condoms. Men were treated presumptively at enrollment and followed up at 1, 2, 4, and 6 months.

RESULTS

Participants in the choice group had a strong preference (P <0.01) for the most popular condom available in Jamaica. This preference did not translate into higher condom use (P = 0.16). The 6-month cumulative probability of first incidence of gonorrhea, chlamydia, or trichomoniasis was slightly higher in the choice group (21%; 95% confidence interval [CI], 15-28%) versus the control group (17%; 95% CI, 11-23%); the difference in the survival curves was not significant (P = 0.35).

CONCLUSION

A choice of condoms may increase perceived acceptability but not lead to increased condom use and subsequently lower sexually transmitted infection rates.

Sex-work harm reduction

Sex work is an extremely dangerous profession. The use of harm-reduction principles can help to safeguard sex workers' lives in the same way that drug users have benefited from drug-use harm reduction. Sex workers are exposed to serious harms: drug use, disease, violence, discrimination, debt, criminalisation, and exploitation (child prostitution, trafficking for sex work, and exploitation of migrants). Successful and promising harm-reduction strategies are available: education, empowerment, prevention, care, occupational health and safety, decriminalisation of sex workers, and human-rights-based approaches. Successful interventions include peer education, training in condom-negotiating skills, safety tips for street-based sex workers, male and female condoms, the prevention-care synergy, occupational health and safety guidelines for brothels, self-help organisations, and community-based child protection networks. Straightforward and achievable steps are available to improve the day-to-day lives of sex workers while they continue to work. Conceptualising and debating sex-work harm reduction as a new paradigm can hasten this process.

Barrier method preferences and perceptions among Zimbabwean women and their partners

In Zimbabwe, adult HIV prevalence is over 25% and acceptable prevention methods are urgently needed. Sixty-eight Zimbabwean women who had completed a barrier-methods study and 34 of their male partners participated in focus group discussions and in-depth interviews to qualitatively explore acceptability of male condoms, female condoms and diaphragms. Most men and about half of women preferred diaphragms because they are female-controlled and do not detract from sexual pleasure or carry stigma. Unknown efficacy and reuse were concerns and some women reported feeling unclean when leaving the diaphragm in for six hours following sex. Nearly half of women and some men preferred male condoms because they are effective and limit women's exposure to semen, although they reportedly detract from sexual pleasure and carry social stigma. Female condoms were least preferred because of obviousness and partial coverage of outer-genitalia that interfered with sexual pleasure.

Comparative acceptability study of the Reality® female condom and the version 4 of modified Reddy female condom in India

OBJECTIVE

Affordable, acceptable and effective female controlled options are required worldwide for prevention of human immunodeficiency virus (HIV) infection and other sexually transmitted diseases. We carried out a comparative acceptability study of Reality and Reddy (version 4) female condoms.

METHODS

Sixty eligible couples were enrolled and randomly assigned to use either Reality or Reddy condom first. They used three Reality condoms and three Reddy condoms each with at least one condom use per week.

RESULTS

Reddy female condom had a significantly better acceptability than Reality condom among women who were less educated and who had not used male condom before. In spite of higher acceptability score, participants were less confident about the Reddy condom for protecting them from HIV disease or pregnancy as compared to a male condom.

CONCLUSIONS

Female condoms are being introduced in India. This study has generated data that is suggestive of optimism for this female controlled option.

Effectiveness of female controlled barrier methods in preventing sexually transmitted infections and HIV: current evidence and future research directions

OBJECTIVES

To evaluate evidence for the effectiveness of female controlled physical and chemical barrier methods in preventing STI/HIV transmission, to examine recent reviews on microbicide development, and to highlight promising research directions. To discuss challenges in conducting effectiveness research and in translating results to public health intervention.

METHODS

Systematic review of articles that examined the disease prevention effectiveness of at least one female controlled barrier method. Review of conference abstracts that presented clinical and preclinical microbicide data.

RESULTS

Randomised controlled trials provide evidence that female condoms confer as much protection from STIs as male condoms. Observational studies suggest that the diaphragm protects against STI pathogens. Several microbicide effectiveness studies are under way and new directions, such as adaptation of therapeutic agents as preventive products, are being examined. Substantial attention is now given to product formulation and novel delivery strategies. Combining microbicide products with different mechanisms of action as well as combining chemical and physical barriers will be necessary to maximise prevention effectiveness.

CONCLUSIONS

Increased investment in the development and identification of female controlled barrier methods offers promise that additional products will be available in the years ahead. Generalizing trial results to a community setting, promoting products that may be less effective than male condoms, and bringing an effective product to scale introduce public health challenges that warrant attention. The need for female controlled barrier methods that provide women with the opportunity to take an active role in reducing their STI/HIV risk are urgently needed and constitute an essential tool to prevent continued spread of these infections.

Female Condom and Male Condom Failure Among Women at High Risk of Sexually Transmitted Diseases

OBJECTIVE

The objective of this study was to study the frequency and determinants of breakage and slippage during female and male condom use.

GOAL

The goal of this study was to determine condom breakage and slippage rate.

STUDY

We conducted a 6-month prospective follow-up study of women attending 2 sexually transmitted disease clinics. Breakage and slippage rates were computed. Logistic regression was used to evaluate baseline characteristics and time-dependent behaviors.

RESULTS

A total of 869 women used condoms in 20,148 acts of intercourse. Breakage was less common for female condoms (0.1%; 95% confidence interval [CI], 0.05-0.21) than for male condoms (3.1%; 95% CI, 2.80-3.42). Slippage was more common for female condoms (5.6%; 95% CI, 5.10-6.13) than for male condoms (1.1%; 95% CI, 0.90-1.28). Rates significantly decreased with use and increased with number of previous failures. From first use to >15 uses, combined failure rate fell from 20% to 1.2% for female condoms (P < 0.0001) and 9% to 2.3% for male condoms (P < 0.01).

CONCLUSIONS

Both condoms may provide good protection against sexually transmitted diseases. Experience determines success with either condom.

Female-condom use in a gender-specific family planning clinic trial

OBJECTIVES

We evaluated female-condom use among women participating in an HIV/STD intervention designed to reduce unprotected sex and expand prevention strategies.

METHODS

Women (n = 360) were recruited from a family-planning clinic and were randomized into an 8- or 4-session intervention group or a control group. We conducted follow-up interviews at 1, 6, and 12 months.

RESULTS

At 1 month, the odds ratios of first-time female-condom use were 9.49 (95% confidence interval [CI] = 4.01, 22.20) in the 8-session group and 4.39 (95% CI = 1.84, 10.49) in the 4-session group relative to controls. Repeated use (n = 21) was predicted by perceived ability to use, by self and partner satisfaction, by dislike of male condoms, and by previous diaphragm use.

CONCLUSIONS

Gender sensitive cognitive-behavioral interventions can influence women to try the female condom. To increase long-term use, interventions may need to include self-insertion practice and involvement of male partners.

Knowledge of, attitudes toward, and stage of change for female and male condoms among Denver inner-city women

Despite availability for a decade and documented acceptability among some groups of women for the method, female condom use is still rare. We surveyed 198 young women (15-25 years old) living in the inner city of Denver about their knowledge of, attitudes toward, and practices regarding female and male condoms. Most (75%) women had ever considered using male condoms; 32% had ever considered using female condoms; and use of either was sporadic. We examined predictors for being in either precontemplation or a later stage along the change continuum at both the bivariate and multivariate levels. Our findings suggest that African Americans and younger women are more likely to contemplate using female condoms. Both lack of knowledge and positive attitudes toward female condoms in this sample suggest that programs designed to raise awareness and knowledge of female condoms while improving their image are needed.
