If the condom fits, wear it: a qualitative study of young African-American men.

OBJECTIVE: To extend the current knowledge base pertaining to condom failure among young African-American men by assessing their experiences with male condom use. METHODS: Qualitative assessments were conducted with 19 African-American men (aged 18-29 years) who had just been diagnosed with an STI and reported using condoms in the previous 3 months. RESULTS: Five categories were identified from the data. These categories pertained to: (1) the "fit and feel" of condoms; (2) condom brand and size; (3) application problems; (4) availability of condoms and lubricants; and (5) commitment to condom use. Common themes included reasons why men believed condoms would break or slip off during sex. Comfort problems, including tightly fitting condoms and condoms drying out during intercourse, were mentioned frequently. Condom associated erection problems were often described. Many men also noted that condom use reduced the level of sexual satisfaction for their female partners. Men noted that finding the right kind of condom was not always easy and it became apparent during the interviews that men typically did not acquire lubrication to add to condoms. Despite their expressed problems with using condoms, men were, none the less, typically emphatic that condom use is an important part of their protective behaviour against STIs. CONCLUSION: Men were highly motivated to use condoms; however, they experienced a broad range of problems with condom use. With the exception of losing the sensation of skin to skin contact, the vast majority of these problems may be amenable to behavioural interventions.

Mechanical failure of the latex condom in a cohort of women at high STD risk.

BACKGROUND AND OBJECTIVES: Mechanical failure may reduce the efficacy of condoms. Little is known about frequency and determinants of condom failure in groups at high risk of sexually transmitted diseases (STD). GOAL: To measure condom breakage and slippage rates and evaluate potential determinants of failure among women attending a public STD clinic. STUDY DESIGN: Women attending an STD clinic participated in a 6-month prospective study of barrier contraception for the prevention of STD. They completed sexual diaries that were reviewed at monthly follow-up visits. No data were collected from the male partners. Baseline characteristics of the participants and time-dependent behaviors were evaluated as potential determinants of condom failure. RESULTS: Of 21,852 condoms used by 892 women, 500 broke during intercourse (2.3%) and 290 slipped (1.3%). Breakage was more common among young, black, single nulliparae who engaged in high-risk behavior. Slippage was more common among married women with children. Failure rates decreased with condom use, with coital frequency, and with use of spermicides. CONCLUSION: User characteristics and experience are determinants of breakage and slippage, which are often regarded only as the effect of product design flaws. Attention to modifiable determinants of failure may improve user counseling and product labeling.

Entertainment television as a healthy sex educator: the impact of condom-efficacy information in an episode of friends.

CONTEXT: Television is often decried as a negative influence on the sexual attitudes and behavior of America's adolescents. However, television occasionally includes messages about the risks of having sex that may have a positive effect on youth. OBJECTIVE: To assess the impact of condom-efficacy messages in an episode of Friends on teens. Design, Setting, and Participants. A national sample of 506 adolescents 12 to 17 years old who had been regular viewers of Friends the previous year were surveyed by telephone shortly after the episode aired. OUTCOME MEASURES: Viewership of the Friends episode, recall of the condom-efficacy message, beliefs about condoms, self-reported change in condom knowledge, and discussions of condom efficacy with parents. RESULTS: At least 27% of the sample saw the episode, and 65% of these viewers recalled its depiction of condom failure resulting in pregnancy. Forty percent of the viewers watched with an adult. Ten percent of viewers talked to an adult about condom efficacy as a result of the show. Compared with other viewers, youth who talked with an adult were more likely to report learning about condoms from the episode and appeared less likely to reduce their perceptions of condom efficacy after the episode. CONCLUSIONS: Entertainment television can serve as a healthy sex educator and can work in conjunction with parents to improve adolescent sexual knowledge.

Evaluation of the efficacy of a nonlatex condom: results from a randomized, controlled clinical trial.

CONTEXT: To reduce unintended pregnancy and HIV infection, it is critical to develop reliable male condoms that will attract consumers who reject conventional latex condoms. METHODS: In a prospective clinical trial conducted in 1998-2000, 830 monogamous couples were randomized in equal numbers to use either a nonlatex condom or a commercial natural latex condom for six months as their only method of birth control. Couples completed detailed reports for the first five condom uses and recorded intercourse and condom use in coital diaries. Pregnancy rates associated with typical and consistent condom use were calculated using life-table analysis. Rates of clinical failure (condom breakage or slippage) were determined for the first five condom uses. RESULTS: During the first five uses, the nonlatex condom had a higher frequency of breakage or slippage during intercourse or withdrawal (4.0%) than latex condoms (1.3%); the breakage rate for the nonlatex condom was about eight times that of latex condoms. The six-cycle typical-use pregnancy rate did not differ significantly between users of nonlatex (10.8%) and latex condoms (6.4%). The six-cycle consistent-use pregnancy rate was higher for nonlatex condom users than for latex condom users (4.9% vs. 1.0%). CONCLUSIONS: The data present strong indirect support for public health messages that promote the use of latex condoms and, for individuals who cannot or are unwilling to use latex condoms, the use of nonlatex condoms for prevention of pregnancy and disease.

A study of the deficiencies in the condom-use skills of gay men.

The use of condoms has been advocated as an important method of reducing the risk of AIDS for such people as gay men, prostitutes, IV drug users, adolescents, hemophiliacs, and others who may become infected with the human immunodeficiency virus (HIV) that causes AIDS. Although AIDS risk-reduction programs have provided information on condoms, none has assessed baseline or followup skills in their use. Because most condom failures have been attributed to errors in use, promoters of condom use should determine whether they are used correctly among those persons targeted for education. A total of 219 gay men entering an AIDS risk-reduction program were asked to demonstrate the use of condoms on a model. All errors made during the demonstration were corrected, and participants were trained during the exercise in the proper use of condoms. More than 80 percent required correction in such things as opening the package, determining the outside of the condom, unrolling the condom to the base of the penis, and expressing air from the space at the tip of the penis. Although proper use of condoms may seem obvious, this small study demonstrates that it must be taught. Since instructions found in condom packaging frequently are not easily understood by potential users, explicit instructions for condom use are needed.

[How well do condoms protect against HIV infection?].

A review of the literature shows that condoms offer good protection against HIV infection and other sexually transmitted diseases. A series of in vitro experiments demonstrate that quality condoms made of latex are impermeable to HIV. In addition, more than 30 in vivo studies confirm that condoms are highly effective in preventing the transmission of HIV. Condom breakage or slippage is relatively uncommon (1-5%). Most condom failure probably results from incorrect or inconsistent usage. Failures may be minimized by increasing experience, choice of quality condoms and by strictly following instructions for use.

An evaluation of a thicker versus a standard condom with gay men.

OBJECTIVES: Although thicker (stronger) condoms are advocated in western Europe for anal intercourse between men, empirical evidence supporting their greater efficacy is lacking. The present study aimed to determine whether a thicker condom is less likely to fail (break or slip off) than a standard (regular thickness) condom, and to establish factors associated with condom failure among gay men. DESIGN: A total of 283 homosexual couples participated in a double-blind, randomized, controlled trial of a standard and a thicker condom. METHODS: Each couple was allocated nine of either condom type. Data were collected on user characteristics, and a questionnaire completed immediately after the use of each condom. The thicker and the standard condoms were used by 142 and 141 couples, respectively. RESULTS: No significant differences were found between the two condom types with respect to either clinical or non-clinical definitions of failure (breakage and slippage). With instances of inappropriate use removed, failure rates for the standard and the thicker condom were low at 2.5 and 2.3%, respectively. User characteristics associated with breakage were lower educational achievement, lack of confidence in condom use, and a history of condom breakage. Behaviours associated with breakage were unrolling the condom before fitting to the penis, longer penis length, absence of additional lubricant, the use of inappropriate lubricant, and longer duration of intercourse. CONCLUSION: Breakage and slippage rates were low for both condom types. There is no evidence from the present investigation to support the use of stronger (thicker) condoms over standard strength condoms among gay men. The appropriate use of additional lubricant should be encouraged.

[How can the male protect himself from HIV infection?].

HIV infection is primarily transmitted via white cells of the blood or sperm. The greatest risk of infection for the passive partner is anal intercourse with ejaculation. The only protection against this way of infection is the use of a special condom by the active partner. Heterosexual coitus carries only a less important risk of HIV infection for the man. Properly used, the condom protects both the man and his female partner against AIDS. In the case of condom failures (spillage, tears), this protection may by preserved through the use of a special condom coated with nonoxinol 9. Finally, in view of their increasing importance, modern condoms are discussed with regard to their production, quality and safety.

Efficacy of the female condom as a barrier to semen during intercourse.

In 1996-1998, the authors measured prostate-specific antigen (PSA) in vaginal fluid to assess the frequency of female condom failure and to evaluate the association of self-reported failure with semen exposure. Women at low risk of sexually transmitted diseases (n = 210) were recruited in Birmingham, Alabama. They were trained to use the female condom, sample vaginal fluid before and after condom use, and complete forms to report problems during each use. Semen exposure was assessed by comparing pre- and postcoital PSA levels in vaginal fluid. A total of 175 women used 2,232 condoms. The rate of semen exposure ranged from 7% to 21% of condom uses, depending on the exposure criterion. Exposure was more likely (21-34%) and more intense (mean postcoital PSA, 24.7 ng/ml) if participants reported a mechanical problem versus other problems or no problems (exposure rate, 5-20% in both instances; mean postcoital PSA, 9.6 and 7.8 ng/ml, respectively). In logistic regression analyses for repeated measurements, user-reported problems accounted for less than 59% of the instances of semen exposure. The female condom prevented semen exposure in 79-93% of condom uses. Exposure was associated with user-reported problems but also occurred in their absence. Reported problems and semen exposure decreased with user experience.

Delayed application of condoms is a risk factor for human immunodeficiency virus infection among homosexual and bisexual men.

The objective of this analysis was to identify risk factors for recent human immunodeficiency virus (HIV) infection among homosexual and bisexual men in Ontario, Canada, during 1998-2001. Participants were recruited through the provincial HIV diagnostic laboratory and through physicians and community organizations. HIV test results were used to identify recent seroconverters (cases). A subsample of 183 men (62 cases and 121 controls) enrolled in the Polaris HIV Seroconversion Study as of June 2001 was analyzed. This analysis focused on sexual behaviors with partners who were HIV-positive or whose HIV status was unknown. In multiple logistic regression, independent risk factors were identified. Rates of unprotected receptive oral, insertive anal, and receptive anal sex and delayed application of condoms during receptive anal sex (RAS) were significantly higher among cases (97%, 41%, 53%, and 32%, respectively) than among controls (73%, 19%, 14%, and 2%). Independent risk factors for HIV infection were RAS without condoms (odds ratio = 4.4, p = 0.0004) and delayed application of condoms during RAS (odds ratio = 5.8, p = 0.01). There was an association with condom failure (breakage or slippage) during RAS that approached significance (odds ratio = 2.9, p = 0.09). Delayed application of condoms for RAS may result in contact with preejaculatory fluid. This behavior, which to date has received little attention, may pose as much risk for HIV infection as fully unprotected RAS.

Changes in sexual behaviour focusing on condom use in STD clinic attenders in Göteborg, Sweden, from 1989 to 1994--a questionnaire survey.

During the 4 years from 1989/1990 to 1994 an increase in the use of condoms was registered. A high frequency of condom failures was reported and probably reflects inappropriate use. More efforts should be made to educate people how to use the condom. The impact of alcohol intake as a risk factor for unsafe sex seems to be significant and should also be stressed in educational safer sex programmes. STD patients are a well-motivated group for information about safer sex and condom use. Health workers in STD clinics have an important task in this context.

Unprotected intercourse for extra money among commercial sex workers in Kinshasa, Democratic Republic of Congo.

This study assessed the extent and correlates of the practice of engaging in unprotected intercourse for extra money among commercial sex workers (CSWs) in Kinshasa, Democratic Republic of the Congo. We conducted a cross-sectional survey using a structured, interviewer-administered questionnaire among a convenience sample of 136 CSWs. More than one-quarter of CSWs (26.5%) engaged in unprotected intercourse for extra money. These CSWs charged about 3.5 times more for unprotected intercourse than for protected intercourse. Multivariate logistic regression showed that CSWs who engaged in unprotected intercourse for extra money were significantly more likely to live or work in non-downtown (lower socioeconomic) areas of Kinshasa (odds ratio [OR] = 3.07), to have at least one child less than six years of age (OR = 2.95), and to know other CSWs who engaged in the same practice (OR = 9.38). We hypothesize that desperate socioeconomic conditions combined with peer/social norms drive the practice of engaging in unprotected intercourse for extra money. Additional circumstances under which Kinshasa CSWs engaged in unprotected intercourse included intercourse with clients who tore their condoms to increase sexual pleasure (58.8% of CSWs), episodes of condom failure (56.8% of CSWs), and unprotected intercourse with regular noncommercial partners (only 5.3% of CSWs with noncommercial partners always used condoms with these partners).

Interrupting herpes simplex virus type 2 transmission: the role of condoms and microbicides.

Condoms act as mechanical barriers to genital infection. In vitro models demonstrate that condoms are almost impermeable to viruses. A small amount of virus may cross the condom, but the condom can still reduce the level of virus exposure by several orders of magnitude. However, in vivo factors, such as condom failure during intercourse, can potentially limit their effectiveness. The weight of available evidence suggests that consistent and correct use of the male condom protects against herpes simplex virus (HSV) infection, as well as other sexually transmitted infections. Female condoms should theoretically protect against HSV infection as they cover a large surface area of potentially infected or susceptible tissues, but research is needed to confirm this. The lack of acceptance, or lack of consistent use, of condoms is the biggest barrier to their effectiveness. There is a need for effective counselling of individuals whose sexual behaviour increases their risk of HSV acquisition, such as young adults. Pregnant women are likely to be receptive to counselling due to the risk of neonatal herpes. No commercially available microbicides specifically inhibit HSV, although many inactivate the virus. More potent and specific microbicides are in development, but may be more expensive than those currently available. Although the effectiveness of condom and microbicide use is not completely proven, there is sufficient evidence to support the promotion of their use by healthcare professionals as an important part of safe sex counselling.

A critical review of the physics and statistics of condoms and their role in individual versus societal survival of the AIDS epidemic.

Condom failure rates for HIV are substantially greater than for pregnancy, even for highly motivated people who may reach the limit set by allowed manufacturing imperfections. This makes condoms ineffective for lifelong protection from HIV-infected sexual partners; therefore, in general, condoms provide inadequate risk reduction for the individual. Nevertheless, they are sufficiently effective that if everyone used condoms, the AIDS epidemic would stop. Quantitative public health goals to reduce the "reproductive rate" of HIV from an estimated 4-12 people infected per infected person to below 1 are needed. Government and scientific testing of condoms could be improved statistically and by utilizing relevant physics.

[The nonoxynol content in condoms is insufficient to inhibit the human immunodeficiency virus (HIV)].

The seven makes of condom which are marketed in Denmark were examined for the nonoxynol content with the object of assessing whether the content of nonoxynol in the condoms is sufficient to present HIV spread in connection with use of the condom and assessed in relation to the defects in effectivity (tearing, holes, overflow of semen, sliding off). Compared with the declared content of nonoxynol of 40 mg (100%) per condom, the following nonoxynol quantities could be demonstrated by methanol/water extraction and subsequent high-performance liquid chromatography: One make of condom contained 65%, two 50-55% and four 25-33%. The nonoxynol content was found to be evenly distributed between the outer and inner surface of the condoms. With a theoretical distribution volume of 6 ml (tearing during vaginal coitus), it was found that three of the makes of condoms examined did not achieve the HIV-inhibiting nonoxynol concentration of 0.05%, by means of measuring the quantity of nonoxynol on the distal 5 cm of the condoms. In anal sex, the distribution volume is greater resulting in lower nonoxynol concentrations and thus increased risk for HIV infection. It is concluded that the nonoxynol content in the condoms marketed in Denmark should be increased in order to inactivate HIV in case of condom failure.

Prostitution and risk of HIV: female prostitutes in London.

OBJECTIVE: To measure the prevalence of HIV and to describe established risk factors in female prostitutes. DESIGN: A cross sectional survey. SETTING: A genitourinary medicine clinic, streets, and magistrates' courts in London. SUBJECTS: 280 female prostitutes recruited between April 1989 and August 1991. MAIN OUTCOME MEASURES: Infection with HIV-1, reported risk behaviours, and prevalence of sexually transmitted infections. RESULTS: 228 of the women had HIV tests, and two (0.9% (95% confidence interval 0% to 2.1%)) were infected with HIV-1. Reported use of condoms was high for commercial clients and low for non-paying partners: 98% (251/255) of women used condoms with all clients and 12% (25/207) with non-paying partners for vaginal intercourse. Twenty two women were current or past injecting drug users. Of the 193 women examined for sexually transmitted infections, 27 had an acute infection (gonorrhoea, chlamydia, trichomonas, or primary genital herpes) at the time of interview. Infection was associated with younger age and increasing numbers of non-paying sexual partners, but not with duration of prostitution, numbers of clients, or reports of condom failures. When age and numbers of non-paying partners were analysed by logistic regression they remained significantly associated with sexually transmitted infections. CONCLUSIONS: A large and diverse sample of prostitutes had a low prevalence of infection with HIV and high levels of use of condoms in commercial sex. There was a significant risk of other sexually transmitted infections associated with prostitutes' non-commercial sexual relationships, in which unprotected sex is common. Interventions to reduce the risk of sexually transmitted infections in prostitutes should address both commercial and non-commercial sexual partnerships.

New CDC condom fact sheet invites criticism. What role did politics play in changes?

Politics and science are clashing over the facts about condoms and what clinicians should tell their patients about their effectiveness. The CDC's updated condom fact sheet puts more emphasis on abstinence and condom failure. A group of Democratic lawmakers sent a letter to the secretary of Health and Human Services accusing the administration of 'playing politics'.

Reducing the risk of sexual HIV transmission: quantifying the per-act risk for HIV on the basis of choice of partner, sex act, and condom use.

BACKGROUND: Sexual acquisition of HIV is influenced by choice of partner, sex act, and condom use. However, current risk-reduction strategies focus mainly on condom use. GOAL: To estimate the contribution of choice of partner, sex act, and condom use on the per-act relative and absolute risks for HIV infection. STUDY DESIGN: Per-act relative risk for HIV infection was calculated with use of estimates of HIV prevalence, risk of condom failure, HIV test accuracy, and per-act risk of HIV transmission for different sex acts. Absolute risks were calculated on the basis of these relative risk estimates. RESULTS: Choosing a partner who tested negative instead of an untested partner reduced the relative risk of HIV infection 47-fold; using condoms, 20-fold; and choosing insertive fellatio rather than insertive anal sex, 13-fold. Choosing one risk-reduction behavior substantially reduces absolute risk of HIV infection for heterosexuals but not for men who have sex with men. CONCLUSION: Clarifying the magnitude of risk associated with different choices may help people make effective and sustainable changes in behavior.
