Objectives. This study assessed the effectiveness of a sexually transmitted disease (STD)/HIV behavior change intervention in increasing women's use of the female condom. Methods. A total of 604 women at high risk for STDs and HIV in New York City, Baltimore, Md, and Seattle, Wash, enrolled in a randomized controlled trial of a small-group, skills-training intervention that included information and skills training in the use of the female condom. Results. In a logistic regression, the strongest predictors of use were exposure to the intervention (odds ratio [OR] = 5.5; 95% confidence interval [CI] = 2.8, 10.7), intention to use the female condom in the future (OR = 4.5; 95% CI = 2.4, 8.5), having asked a partner to use a condom in the past 30 days (OR = 2.3; 95% CI = 1.3, 3.9), and confidence in asking a partner to use a condom (OR = 1.9; 95% CI = 1.1, 3.5). Conclusions. Clinicians counseling women in the use of the female condom need to provide information, demonstrate its correct use with their clients, and provide an opportunity for their clients to practice skills themselves.
Although sexually transmitted diseases (STDs) have been largely controlled in the vast majority of countries in the developed world, they tragically remain a serious health problem in the developing world and in many regions of the United States.1,2 Among the 12 million cases of STDs estimated to occur annually in the United States, almost two thirds are in women.1 The medical consequences of STDs in women contribute greatly to morbidity associated with reproductive health, including pelvic inflammatory disease, infertility, ectopic pregnancy, chronic pelvic pain, compromised birth outcomes, and cervical cancer.3,4 Studies also show that STDs increase the risk of acquiring HIV.5,6 Worldwide, approximately 14.8 million women are estimated to be infected with HIV, accounting for almost half of HIV-infected adults.7 In the United States, women represent an increasing proportion of new infections and accounted for approximately 25% of AIDS cases reported in 1999.8 More than 80% of cases in US women occur in African Americans and Latinas. The most frequently reported mode of infection for women is heterosexual transmission. The male condom has proven to be highly effective in reducing the transmission of HIV and some STDs.9 For many reasons involving economic and social inequalities, as well as gender power dynamics, women may be unable to negotiate with their male partners to use male condoms consistently.10,11 Thus, there is an urgent need to provide expanded options for women to protect themselves from acquiring STDs and HIV.12,13 The female condom is 1 option that has been proposed. Approved for use in protection against STDs and unintended pregnancy by the US Food and Drug Administration in 1993, the Reality female condom (The Female Health Co, Chicago, Ill) has been estimated to reduce the rate of STD transmission by 97% when used exactly as recommended by the manufacturer.14 Clinical trials are under way to empirically test these estimates.15 A recent review of 42 studies from the developing and developed world examined the acceptability of the female condom among a wide assortment of women who had used the product, including commercial sex workers, women attending family planning clinics, and health care workers.11 Although most of the studies had small sample sizes and were not experimentally designed, some common patterns did emerge. Overall, general acceptability of the product ranged from 52% to 95%, although actual usage was substantially lower.16,17 Female condom studies in the United States have been limited. Findings in 2 studies of African American women were mixed. One study of 52 women who were given the product after a demonstration reported that 79% had used 1 or more in a 2-week period and that 73% preferred the female to the male condom.18 This finding contrasts with a study of 178 women who were given a selection of 5 barrier methods to try. Women in this study preferred the male condom to the female condom 2 to 1.19 Only 1 published US study to date has assessed the acceptability of the female condom in a randomized controlled intervention trial.20 Women (n = 231) in the intervention were introduced to the female condom and encouraged to use the product in the week following the demonstration. At the time of the 1-month follow-up interview, 29% of women had used the product at least once during the period since the intervention, and of those women, 29.9% used it for at least half of the episodes of sexual intercourse. Women who tried the product were significantly more likely to be African American (39%) than Hispanic (30%) or White (18%). They were also more likely to be between the ages of 25 and 34, to live with a partner, to have a history of an STD, or to have been tested for HIV. The present study assesses the effect of a multisite, randomized controlled STD/HIV behavior change intervention on women's use of the female condom. The intervention sessions included components shown to be effective in STD/HIV risk reduction: education, motivation, and behavioral skills.21 Investigators hypothesized that increasing knowledge, coupled with introducing opportunity for skills acquisition in the use of the female condom, would increase the acceptability and use of the product among intervention women.
The Women in Group Support (WINGS) project is a randomized trial of an education, skills-training, and support-group intervention to increase preventive health behaviors for STDs and HIV in women at high risk for infection. Flyers, newspaper advertisements, community presentations, and on-site recruitment strategies were used to recruit women from 3 cities (Baltimore, Seattle, and New York City) from May 1995 to July 1997. Sources of recruitment included community-based programs, family planning clinics, STD clinics, advertising, and waiting lists for other research studies. HIV-negative women were eligible if they were aged 17 years or older, had had vaginal or anal sex with a male partner during the past 3 months, and had 1 of the following risk factors during the past year: a diagnosed STD, 3 or more sexual partners, use of intravenous drugs, or sex with someone who (1) had other sexual partners, (2) injected illicit drugs, or (3) had sexual intercourse with a prostitute. The New York site differed from the 2 other sites by limiting participation to women aged 17 to 22 years. Names of eligible women who completed the 1.5-hour baseline interview and skills assessments were logged into a record file. After 20 women had been recruited for a cohort, they were invited to attend a meeting. Women who attended the meeting were randomized into the intervention or control group. Women in the control group participated in a 1-hour session featuring a nutrition video on healthy food choices. Women were reimbursed $10 to $20 (depending on the site) to attend the control and each intervention session.
Intervention
Data Collection
Measures Skills demonstration. At the end of the interview, women were given a female condom and asked to demonstrate use on a pelvic model. Interviewers rated the respondent's performance on the following aspects: (1) held the pouch with open end hanging down; (2) while holding outside pouch, squeezed inner ring while inserting; (3) inserted squeezed condom into vaginal opening, making sure pouch was straight, not twisted; (4) with finger inside, pushed inner ring and pouch the rest of the way up into the vagina. For each of these aspects, respondents were rated "0" (no), "1" (yes), or "9" (refused). All interviewers were trained and observed for skills demonstration scoring to ensure interrater reliability. At the end of the baseline skills assessment, women in the control group were given printed instructions on correct use of male and female condoms, but they received no verbal instruction or demonstration.
Self-administered questionnaire.
Subjects were also asked to complete a self-administered questionnaire that contained scales measuring general mastery23 (
Data Analysis Intervention and control groups were compared at baseline and at 3-month follow-up for use of the female condom with a partner or for practice, attitudes about the female condom, skills in its use as demonstrated on a pelvic model, and future intention to use the female condom.
Female condom use at baseline was determined by an affirmative response to any of several questions regarding whether or not the respondent had ever tried the female condom or had used it within the past 3 months, for contraception, disease prevention, or practice. Female condom use at follow-up was defined as use within the past 3 months for pregnancy or STD prevention. Attitudes toward female condoms were measured by a 6-item scale (comfort, ease of insertion, ease of removal, sensation, effects on movement of penis, and tendency to stay in place) (
A total of 604 women completed baseline interviews and were randomly assigned to either the intervention or the control arm of the study between May 1995 and August 1997; 526 of them (87%) completed a 3-month follow-up questionnaire. On the basis of demographic characteristics or variables of interest for this analysis, there were no significant differences between women who completed 3-month follow-up questionnaires and those who did not, except that completers perceived a greater risk of getting an STD at baseline (P = .01). Table 1
At follow-up, however, the groups differed on all female condom measures. Table 2
When we compared women, both in the intervention and control groups, who at the 3-month follow-up visit used the female condom with women who did not (Table 3
Users were significantly more likely to have asked a main sexual partner to use a condom in the past 30 days and to report that they that were sure they could use a male condom every time with a main sexual partner. Users were also more likely to say that they had asked a nonmain sexual partner to use a male condom in the past 30 days, but they were not more likely to report that they were sure they could use a male condom every time with another partner. There were no significant differences between users and nonusers in self-efficacy for refusing unsafe sexual intercourse with either main or other partners. In addition, there were no differences between users and nonusers in perceived risk for acquiring an STD or HIV, number of sexual partners in the past 3 months, intentions regarding pregnancy, mastery, or self-esteem (data not shown).
We conducted a logistic regression analysis to examine predictors of female condom use at follow-up, controlling for baseline differences (Table 4
This study demonstrates that women at high risk for STDs and HIV who were exposed to an intervention with information and skills training developed more positive attitudes toward the female condom, demonstrated increased skills in using the product, and were significantly more likely to use the female condom and to say that they intended to use it in the future than were women in a control group. Women in the control group also increased their use of the female condom from baseline, possibly as a result of having been exposed to the product at the baseline interview. Women in both groups were given product samples, thus reducing a possible financial barrier. Female condom users were significantly more likely at baseline to have asked a partner (main and other) to use a male condom in the past 30 days. This finding is consistent with other studies that have shown that use of the female condom with a male partner requires negotiation.11 Thus, the female condom is not strictly "female controlled," although it may give women more control than the male condom. The female condom may not be an option for women who lack the ability to negotiate with their male partners. Several studies have shown that women more frequently use male condoms with nonmain sexual partners than with main sexual partners.25 In contrast, the present study shows that women with nonmain sexual partners only were less likely to have used the female condom. It may be that, unlike the male condom, the female condom is not well known to the general public and thus requires some discussion with a partner. Women may feel more comfortable in doing so with a main sexual partner. Rates of acceptability in this and other US studies are lower than in most studies in the developing world. This fact may be related to greater motivation for women in developing countries to try barrier methods due to the higher rates of HIV in those countries, lack of other available options, cultural differences, or differences in educational approaches. This study has implications for the design of educational interventions to introduce women to the female condom. Clinicians counseling women in its use need to provide information in culturally appropriate ways, demonstrate its correct use with their clients, and provide an opportunity for their clients to practice skills themselves, either with a pelvic model or through self-demonstration. Provider attitudes toward the product may also be an important factor in women's decisions to use the product.
