Prevalence and incidence of HIV among incarcerated and reincarcerated women in Rhode Island

This study explores recent temporal trends in HIV prevalence among women entering prison and the incidence and associated risk factors among women reincarcerated in Rhode Island. Results from mandatory HIV testing from 1992 to 1996 for all incarcerated women were examined. In addition, a case control study was conducted on all seroconverters from 1989 to 1997. In all, 5836 HIV tests were performed on incarceration in 3146 women, 105 of whom tested positive (prevalence, 3.3%). Between 1992 and 1996, the annual prevalence of HIV among all women known to be HIV-positive was stable (p = .12). Age >25 years, nonwhite race, and prior incarceration were associated with seropositivity. Of 1081 initially seronegative women who were retested on reincarceration, 12 seroconverted during 1885 person-years (PY) of follow-up (incidence, 0.6/100 PY). Self-reported injection drug use (IDU; odds ratio [OR], 3.7; 95% confidence interval [CI], 1.3-10.1) was significantly associated with seroconversion, but sexual risk was not (OR, 1.1; 95% CI, 0.4-3.5). Incarceration serves as an opportunity for initiation of treatment and linkage to community services for a population that is at high risk for HIV infection.     

High incidence of HIV-associated mortality among black and Hispanic infants and women of childbearing age in the United States 1990-2001

This study examined HIV-associated mortality in infants and in women of childbearing age (15-44 years) in the United States from 1990-2001. HIV-associated deaths were identified from national vital records using multiple cause-of-death data. HIV-associated mortality was higher in black and Hispanic women than in white women (rate ratio(black) = 13.5, 95% CI = 13.2-13.8; rate ratio(Hispanic) = 2.4, 95% CI = 1.9-3.2). Racial/ethnic trends in infant mortality rates from HIV reflected trends observed in women (rate ratio(black) = 16.3, 95% CI = 13.5-19.7; rate ratio(Hispanic) = 3.4, 95% CI = 3.3-3.5). HIV-associated mortality decreased in infants and in women of childbearing age following the availability of highly active antiretroviral therapy, but the decrease was considerably less marked in black women than in women of other racial/ethnic groups. Our findings indicate the need for increased emphasis on prevention of HIV mortality in black and Hispanic women and infants. Reduction of HIV prevalence in young women may also prevent infant mortality from HIV by reducing mother-to-child transmission.     

New sexually transmitted diseases in HIV-infected patients: markers for ongoing HIV transmission behavior

OBJECTIVE: The objective of this study was to describe the rate of new sexually transmitted diseases (STDs) among HIV-infected patients and to define the behavioral and clinical characteristics of HIV-infected patients who return with a new STD in follow-up. DESIGN: The study design was a record-based clinical cohort study focusing on patients testing HIV-seropositive in the STD clinics of Baltimore, Maryland from 1993 to 1998. METHODS: The authors identified those HIV-infected patients later diagnosed with an STD in follow-up and compared their demographic, behavioral, and clinical characteristics with those who were not diagnosed with an STD in follow-up. RESULTS: Of 796 men and 354 women with HIV infection, 13.9% of men and 11.9% of women were diagnosed with an STD after their initial HIV diagnosis. HIV-infected men returned with a new STD at a rate of 7 cases per 100 person-years; HIV-infected women returned at a rate of 5.6 cases per 100 person-years. In men, multiple sex partners and sex worker contact were associated with a subsequent STD diagnosis (OR = 1.67, p =.037; OR = 1.82, p =.015, respectively). In women, age younger than 30 years was associated with the diagnosis of an STD after the diagnosis of HIV infection (OR = 2.94, p =.0009). CONCLUSIONS: Patients diagnosed with HIV in an STD clinic setting commonly return with new STDs in follow-up, suggesting continued exposure of HIV to others. More intensive screening and counseling interventions focused on STD prevention in those with HIV infection is a necessary HIV prevention strategy.     

AIDSCAP initiative expands prevention efforts for women

By 2000, women will likely comprise 50% of HIV-infected persons worldwide. Women, regardless of number of sexual partners, are especially vulnerable to HIV. One act of intercourse puts women at an 18 times greater risk than men of acquiring HIV. Traditional gender roles denying women the power to protect their own health exacerbate their biological susceptibility to HIV infection. AIDSCAP's Women's Initiative (AWI) aims to secure culturally and gender-sensitive AIDSCAP interventions and strategies and to advance AIDSCAP's leadership role in developing HIV/AIDS prevention models for women. More than 50% of AIDSCAP current projects target women. AWI integrates a broader gender perspective into AIDSCAP's project design, technical assistance, evaluation and monitoring, and policy projects. It has expanded target women's groups beyond the groups traditionally considered at high risk. To date, various AIDSCAP projects have trained and educated about one million women. The Christian Reformed World Relief Committee (CRWRC) is involved in HIV/AIDS prevention activities. Its AIDS and Sexually Transmitted Disease (STD) Health Promotion Prevention Program with Market Women in Senegal targets self-employed market women and urban female youth in Dakar, Kaoloack, and Thies. CRWRC worked with two women's groups to develop a sexual health promotion package with HIV/AIDS and STD IEC (information, education, and communication) materials and has trained 20 facilitators to use the promotion package. It helps the two collaborating groups to develop their organization capacities so they can implement and evaluate sustainable HIV/STD prevention programs. AIDSCAP also supports training of Kenyan family planning provider activities in HIV prevention of the JSI Family Planning Sector Project. It collaborates with the Center of Women Workers in Haiti to provide women factory workers IEC and condoms to promote risk reduction behavior. AWI also conducts research and policy activities (e.g., perceptions of the female condom in 3 countries).     

HIV seroconversion among public sexually transmitted disease clinic patients: analysis of risks to facilitate early identification

OBJECTIVES: We identified risks for HIV seroconversion among public sexually transmitted disease (STD) clinic patients. DESIGN: This was a retrospective cohort study conducted January 1993 through October 2002 of STD clinic attendees aged > or =12 years in Baltimore, Maryland. METHODS: A negative HIV enzyme immunoassay (EIA) test was required for staggered cohort entry. Observation time was 30 days to 3 years. The outcome for multivariate Poisson regression was HIV seroconversion (positive EIA and/or Western blot test) compared among patients with or without sexual risk behaviors, drug use, an STD diagnosis, and signs and symptoms at an initial HIV test. RESULTS: One hundred twenty-five HIV seroconversions occurred among 10,535 individuals and 13,693 person-years of observation, for an incidence of 0.91 HIV seroconversions per 100 person-years (95% confidence interval [CI]: 0.76 to 1.09). Median time to HIV seroconversion was 1.54 years (95% CI: 1.11 to 1.73). In multivariate analysis, increased HIV seroconversion risk was associated with older age, drug use, a sexual partner with syphilis or HIV, genital ulcers, and gonorrhea. HIV incidence per 100 person-years was 4.86 for subjects with an HIV-positive sexual partner, 3.06 for those with injection drug use, and 2.40 for those with genital ulcers. CONCLUSIONS: We found a high rate of HIV seroconversion among STD clinic patients with specific risks. Algorithms with HIV RNA testing targeted to patients at the highest risk for seroconversion may optimize prevention and resource utilization.     

Age differences in sexual partners and risk of HIV-1 infection in rural Uganda

OBJECTIVES: To assess whether differences in age between sexual partners affect the risk of HIV infection in female adolescents and young adults. METHODS: A total of 6177 ever sexually active women aged 15 to 29 years completed a sociodemographic and sexual behavior questionnaire and provided a blood sample for HIV-1 serology. The age difference between partners was categorized as men 0 to 4 years older (referent group), 5 to 9 years older and 10 or more years older. HIV prevalence and incidence were assessed, and adjusted RR was estimated by multivariate regression. RESULTS: Prevalent HIV-1 infection in female participants increased with older male sexual partners. Among women aged 15 to 19 years, the adjusted risk of HIV infection doubled (RR = 2.04; 95% CI: 1.29-3.22) among those reporting male partners 10 or more years older compared with those with male partners 0 to 4 years older; among women 20 to 24 years of age, the RR was 1.24 (95% CI: 0.96-1.60). The attributable fraction (exposed) of prevalent HIV infection in women aged 15 to 24 years associated with partners 10 or more years older was 9.7% (95% CI: 5.2-14.0). HIV incidence did not increase with differences in age of partners. CONCLUSION: The age difference between young women and their male partners is a significant HIV risk factor, suggesting that high HIV prevalence in younger women is caused, in part, by transmission from older male partners.     

Study finds peer education is an effective prevention method

A comparative study conducted among factory workers in Zimbabwe demonstrated that peer education has the potential to reduce the incidence of HIV. This study, sponsored by the University of Zimbabwe in collaboration with Stanford University (US), was the first evaluation of a health education strategy to use HIV infection as the measure of effectiveness. HIV incidence rates decreased significantly more in the factories where peer education was offered than in those without such a program. Workers at all factories were offered HIV testing and counseling--interventions associated with behavioral change in other studies. Thus, the effect of peer education on HIV incidence was over and above the effects of these other interventions. Another survey, conducted among factory workers in Harare, found that early-stage, effective treatment of sexually transmitted diseases (STDs) was associated with significant decreases in HIV incidence. Workers with a history of an STD were 5 times as likely as their co-workers without such a history to be HIV-positive. Risk factors for STD history included single marital status, contact with prostitutes, and multiple sex partners. These factory-based studies suggest the effectiveness of an HIV/AIDS prevention strategy based on peer-led health education, condom distribution at the workplace, and aggressive treatment of STDs.     

Is sexual contact with sex workers important in driving the HIV epidemic among men in rural Zimbabwe?

OBJECTIVE: To establish the importance of commercial sex in driving the HIV epidemic in the general population by determining risk factors for HIV infection among male mine and farm workers and estimating the fraction of prevalent HIV infections attributable to sexual contact with sex workers (SWs). SETTING: Five commercial farms and 2 mines in Mashonaland West, Zimbabwe. METHODS: A cross-sectional interviewer-administered questionnaire and urine survey of 1405 male workers. Urine samples were tested for HIV antibodies by a particle agglutination test and enzyme-linked immunosorbent assay and for Chlamydia trachomatis and Neisseria gonorrhoeae using a polymerase chain reaction assay. RESULTS: The overall prevalence of HIV antibodies was 27.3% (95% confidence interval [CI]: 24.8 to 29.5), that of C. trachomatis was 1.5% (95% CI: 1.0 to 2.1), and that of N. gonorrhoeae was 0.5% (95% CI: 0.1 to 0.9). A total of 48.4% (95% CI: 45.8 to 51.0) of men reported ever having had sexual contact with an SW, and 29.3% (95% CI: 26.9 to 31.7) reported contact in the past year. HIV was more common among men who reported SW contact on univariate (1.9% [95% CI: 1.5 to 2.4]) and multivariate (1.4% [95% CI: 1.0 to 1.8]) analysis after adjusting for confounding. HIV was also strongly associated with self-reported genital ulceration in the previous 6 months (adjusted odds ratio [OR] = 3.1, 95% CI: 2.2 to 4.3). Genital ulceration and SW contact were highly correlated. A total of 19.6% of HIV infections in men could be attributed to ever having had sexual contact with an SW (95% CI: 10.8 to 27.6). CONCLUSIONS: An appreciable proportion of HIV infection in men is attributable to sexual contact with SWs. Consideration should be given to developing interventions that target male clients of SWs.     

Prevalence and correlates of HIV infection among young injection drug users in San Francisco

OBJECTIVE: We assessed the prevalence of HIV infection and associated risk behaviors among street-recruited young injection drug users (IDUs) in San Francisco. METHODS: In a cross-sectional study, 304 young (age <30 years) IDUs with a history of injecting in the previous 30 days were interviewed and tested for antibodies to HIV. Analyses assessing independent associations with HIV infection were limited to males only, due to the low number of infections in women. RESULTS: The prevalence of HIV infection was 5.3% overall but was highly stratified by gender and sexual preference (15.6% among homosexual/bisexual men vs. heterosexual men) and recruitment neighborhood (18% in the Polk Street area). Of 16 HIV infections, 14 (88%) were in males. Factors independently associated with HIV infection in males included sexual preference (homosexual/bisexual vs. heterosexual: adjusted odds ratio [AOR], 7.5; 95% confidence interval [CI], 1.5-36.6), recruitment neighborhood (Polk Street neighborhood vs. other neighborhoods: AOR, 4.8; 95% CI, 1.4-16.7), and duration of residence in San Francisco (>or=1 year vs. <1 year: AOR, 11.8; 95% CI, 1.4-95.8). CONCLUSIONS: The prevalence of HIV infection was highest among male IDUs who have sex with men. The strong associations between HIV infection and sexual orientation and HIV infection and recruitment locale suggest that risk may be attributable largely to sexual risk. In addition to successful prevention efforts aimed at reducing needle-associated risk, current intervention models aimed at young IDUs should target high-risk neighborhoods and emphasize sexual risk reduction measures, in particular among men who have sex with men.     

Declining HIV infection rates among recently married primigravid women in Pune, India

BACKGROUND: A single recent study has suggested a decrease in HIV risk for women attending antenatal clinics (ANCs) in southern India. Yet, some have questioned the validity of the Indian national surveillance data and analyses. Previous studies suggest that the only major HIV risk factor for married Indian women is the risk behavior of their husbands. Therefore, to address concerns about potential selection bias in the analysis of sentinel surveillance data from multiple sites, we estimated the trajectory of HIV transmission rates among recently married, monogamous, primigravid women attending a single large ANC in Pune, India. METHODS: Participants were self-referred, young, primigravid women from 18 to 27 years of age consenting to HIV screening. Time trends in HIV prevalence over 3.5 years were evaluated by logistic regression adjusted for age. HIV incidence was estimated by dividing the number of HIV-infected mothers by an estimate of exposure person-time, which was an estimate of the average age-specific duration of marriage. RESULTS: Between August 16, 2002 and February 28, 2006, 30,085 (79.5%) of 37,858 pregnant women consented to HIV screening; 10,982 (36.5%) were primigravid and their age range was from 18 to 27 years. HIV infection risk declined over 3.5 years among primigravid women. An estimated 19,739 person-years (PYs) of exposure yielded an overall HIV incidence rate 1.25/100 PYs (95% confidence interval [CI]: 1.10 to 1.42). Estimated HIV incidence decreased from 2.2/100 PYs (95% CI: 1.6 to 3.0) in 2002 to 2003 to 0.73/100 PYs (95% CI: 0.5 to 1.0) in 2006. DISCUSSION: HIV infection risk among young primigravid women in Pune seems to have decreased over the past 3.5 years. A decreasing HIV risk among pregnant women in Pune would also decrease the number of HIV-exposed infants. We hypothesize that decreased high-risk sexual behavior among young recently married men is most likely contributing to a decreasing risk to their wives and children in Pune.

HIV-1 incidence among male workers at a sugar estate in rural Malawi

OBJECTIVES: To determine incidence of HIV and associated risk factors in two cohorts of men working at a sugar estate in rural Malawi. DESIGN: Prospective studies. METHODS: After counseling and obtaining informed consent, male workers were tested for HIV-1 and syphilis. Baseline HIV-seronegative men were enrolled in two follow-up studies in 1994 and 1998, and were retested for HIV and syphilis at 6-month follow-up visits. Demographic, behavioral, and medical history was collected at baseline. Cumulative HIV incidence based on Kaplan-Meier methods was estimated. HIV incidence was also estimated per 100 person-years (p-y). Crude and adjusted rate ratios for the association of risk factors with incident HIV infection were obtained using Cox proportional hazards models. RESULTS: HIV prevalence was 24.3% among 1692 men screened in 1994 and 21.0% among 1349 men screened in 1998 (p <.03). HIV incidence was extremely high during 1994 to 1995 (17.1% for that 1-year period). Incidence dramatically declined in 1996, averaging about 3.5% per year from 1996 through 1999. Among men enrolled in the 1998 cohort, HIV incidence during 1998 to 1999 was 3.8%. After controlling for potential confounders reactive syphilis was associated with a twofold risk of HIV acquisition in each cohort. CONCLUSIONS: Urgent preventive measures are needed to control the spread of HIV in this economically important occupational cohort. In addition to conventional educational messages to reduce risky sexual behavior, treatment of other sexually transmitted diseases should be considered.     

HIV incidence among men diagnosed with early syphilis in Atlanta, San Francisco, and Los Angeles, 2004 to 2005

BACKGROUND: Syphilis outbreaks among men who have sex with men (MSM) in the United States have raised concerns about increased HIV transmission in this population. We sought to estimate HIV incidence among men diagnosed with primary or secondary (P&S) syphilis in sexually transmitted disease (STD) clinics in Atlanta, San Francisco, and Los Angeles. METHODS: We analyzed deidentified sociodemographic information from routine syphilis surveillance databases and matching remnant sera from consecutive male patients with P&S syphilis who were tested for syphilis at 3 public health laboratories during January 2004 through January 2006. Deidentified sera positive for Treponema pallidum by particle agglutination were screened for HIV-1 antibodies by enzyme immunoassay (EIA). Specimens that were confirmed HIV-positive by Western blot analysis were then tested for recent HIV infection using the less sensitive (LS) HIV-1 Vironostika EIA and BED HIV-specific IgG/total IgG assay. RESULTS: Of 357 men with P&S syphilis (98 in Atlanta, 151 in San Francisco, and 108 in Los Angeles), 32% had primary syphilis and 85% were MSM (12% no MSM risk and 3% no information). The median age was 36 years; 40% were white, 31% black, 20% Hispanic, and 8% other. Among men with P&S syphilis, 160 (45%) were HIV-positive, of whom 8 were classified as having acquired recent HIV infection by the LS-Vironostika EIA (all confirmed by BED) and had no history of antiretroviral use or HIV-positive results >6 months earlier. Seven of the 8 men with recent HIV infection were MSM. The estimated HIV incidence was 9.5% per year (95% confidence interval [CI]: 2.9 to 16.0) among all men and 10.5% per year (95% CI: 2.7 to 18.3) among MSM. CONCLUSIONS: We found high HIV incidence among a high-risk population of US men diagnosed with P&S syphilis in STD clinics in Atlanta, San Francisco, and Los Angeles. Intensive integrated HIV/STD prevention programs are needed for this population.     

Evidence of a brief surge in safer sex practices after HIV testing among a sample of high-risk men and women

OBJECTIVES: We investigated the association between recent HIV testing and safer sex among clients of a publicly funded sexually transmitted disease (STD) clinic. METHODS: Of 401 men and women who were anonymously assessed on sexual risk, HIV testing, STD history, motivations for behavior change, and exposure to HIV prevention education, we studied 292 sexually active respondents who reported previous testing for HIV. Outcome measures included condom use at last intercourse and frequent (at least "most of the time") condom use during the past 3 months. Logistic regression was used to examine the association between each outcome and length of time since HIV testing, controlling for other putative predictors of condom use. RESULTS: The sample consisted mainly of African-American (79%) heterosexual (95%) men and women, almost half (44%) of whom were less than 26 years old. Regression analyses indicated that recent HIV testing was significantly associated with safer sex. Prevalence of condom use at last intercourse was highest among respondents who received an HIV test <3 months before the survey, whereas frequent condom use during the past 3 months peaked among clients who had been tested 3 to 5 months before assessment. CONCLUSIONS: The occurrence of a brief "surge" in safer sex among recent HIV counseling and testing clients, regardless of serostatus, suggests that these individuals may be particularly amenable to additional interventions designed to achieve longer term reductions in risky behaviors.     

Hiv risk behavior in male and female russian sexually transmitted disease clinic patients

Russia is experiencing one of the fastest growing HIV epidemics in the world. Russian sexually transmitted disease (STD) clinic patients are at elevated risk for infection with HIV and other STDs due to unsafe sexual behaviors. Future risk reduction intervention efforts for this group must be grounded in a solid understanding of the factors associated with risky behaviors. We collected information about the sexual behaviors, substance use, protective strategies, and HIV-related attitudes of 400 high-risk men and women presenting at an STD clinic in a major Russian metropolis. Alcohol use in conjunction with sexual activity was common in this sample (85%). One-third of study participants had more than 1 partner in the past 3 months, and about half (48%) of the sample had previously been diagnosed with an STD. However, despite this evidence of high-risk behavior, most participants (67%) reported using condoms less than half the time. High-risk behavior was associated with substance use and lower perceived severity of AIDS. Self-protective strategies differed by gender: men reported higher condom use rates whereas women reported efforts to limit their number of sexual partners. This study has important implications for the development of culturally tailored interventions to help stem the spread of HIV in Russia.     

HIV seroincidence among patients at clinics for sexually transmitted diseases in nine cities in the United States

Although the numbers of newly reported diagnoses of AIDS decreased in the 1990s, it is not clear whether they reflect a decreasing number of new HIV infections. Direct measurement of HIV incidence through follow-up cohort studies is difficult and costly. We estimated HIV incidence and trends in incidence among men who have sex with men (MSM) and heterosexual men and women at clinics for sexually transmitted diseases (STDs) by using a recently developed serologic testing algorithm that requires only a single blood specimen. Cross-sectional anonymous serosurveys were conducted at 13 STD clinics in nine cities in the United States from 1991 through 1997. Before anonymous HIV testing, demographic and clinical information was abstracted. Of 129,774 specimens tested, 362 (0.28%) were from persons estimated to be recently infected. Incidence among MSM was 7.1% (95% confidence interval (CI): 4.8-10.3), 14 times higher than that among heterosexuals, which was 0.5% (CI: 0.4- 0.7). Incidence among MSM and heterosexuals remained unchanged during the time studied. Decreasing rates of new AIDS diagnoses in the 1990s do not reflect stable rates of new HIV infections among MSM and heterosexual patients attending these clinics.     

Time trends in HIV incidence among homosexually active men seen at sexual health clinics in Australia, 1993-1999.

BACKGROUND: Increases in sexual risk behaviour have recently been reported among homosexually active men in Australia and in other industrialised countries, potentially facilitating an increase in HIV incidence. OBJECTIVE: To monitor HIV incidence among homosexually active men seen through a network of sexual health clinics in Australia. STUDY DESIGN: Selected metropolitan public sexual health clinics provided counts of the number of people seen at the clinics during a calendar year, the number voluntarily tested for HIV antibody and the number newly diagnosed with HIV infection, broken down by sex, age group, HIV exposure category and HIV antibody testing history. HIV incidence was estimated among homosexually active men with a history of a negative test in the 12 months prior to last being seen in a calendar year. RESULTS: Of 23924 men seen at the clinics in 1993-1999 with a reported history of male homosexual contact, 7440 (31.1%) had a negative test in the 12 months prior to last being seen in a calendar year. The percentage of men with a recent negative test declined significantly over time, from more than 33% in 1994-1996 to 29% in 1999 (P=0.003), and with increasing age, from 34.3% among men aged 25-29 years to 27.4% among men aged 40 years or older (P<0.0005). A total of 5346 (71.9%) men were retested for HIV antibody within 12 months of the last negative test. The percentage of men retested declined significantly over time, from 77.8% in 1994 to 67.2% in 1999 (P=0.021) but did not change by age group (P=0.132). Overall, 56 men were newly diagnosed with HIV infection. Estimated HIV incidence was 2.1% in 1993-1999; incidence did not change significantly by year (P=0.498) or age group (P=0.757). CONCLUSION: HIV incidence has remained stable among homosexually active men seen through a network of sexual health clinics in Australia.     

Sustained changes in sexual behavior by female sex workers after completion of a randomized HIV prevention trial

INTRODUCTION: Behavioral interventions in female sex workers (FSWs) are associated with changes in sexual behavior and reduced rates of sexually transmitted infections (STIs) and HIV We examined the sustainability of such interventions. METHODS: HIV-uninfected Kenyan FSWs were enrolled in a clinical trial that provided free male condoms, community and clinic-based counseling, and STI management. After trial completion, scaled-back community-based resources remained in place. More than a year later, women were invited to complete a follow-up behavioral questionnaire and to undergo STI/HIV counseling and testing. Individual changes in sexual behavior were assessed by paired analysis. RESULTS: One hundred seventy-two women participated in the resurvey 1.2 years after trial termination. Client numbers had risen (paired t test, P < 0.001), but condom use had also increased (P < 0.001); both remained substantially lower than at enrollment. Regular partners accounted for a greater proportion of unprotected FSW sexual encounters (35% vs. 10%; P < 0.001). Only 9 (5.2%) of 172 women had a conventional STI, and the follow-up HIV incidence of 1.6 per 100 person-years (PYs) was similar to that during the trial period (3.7 per 100 PYs). Incident STIs and HIV were associated with the frequency of unprotected sex and younger age. CONCLUSIONS: Less intensive community-based risk reduction services after clinical trial termination may support ongoing reductions in STIs and HIV among high-risk FSWs.     

Effectiveness of HIV/STD sexual risk reduction groups for women in substance abuse treatment programs: results of NIDA Clinical Trials Network Trial

CONTEXT: Because drug-involved women are among the fastest growing groups with AIDS, sexual risk reduction intervention for them is a public health imperative. OBJECTIVE: To test effectiveness of HIV/STD safer sex skills building (SSB) groups for women in community drug treatment. DESIGN: Randomized trial of SSB versus standard HIV/STD Education (HE); assessments at baseline, 3 and 6 months. PARTICIPANTS: Women recruited from 12 methadone or psychosocial treatment programs in Clinical Trials Network of National Institute on Drug Abuse. Five hundred fifteen women with >or=1 unprotected vaginal or anal sex occasion (USO) with a male partner in the past 6 months were randomized. INTERVENTIONS: In SSB, five 90-minute groups used problem solving and skills rehearsal to increase HIV/STD risk awareness, condom use, and partner negotiation skills. In HE, one 60-minute group covered HIV/STD disease, testing, treatment, and prevention information. MAIN OUTCOME: Number of USOs at follow-up. RESULTS: A significant difference in mean USOs was obtained between SSB and HE over time (F = 67.2, P < 0.0001). At 3 months, significant decrements were observed in both conditions. At 6 months, SSB maintained the decrease and HE returned to baseline (P < 0.0377). Women in SSB had 29% fewer USOs than those in HE. CONCLUSIONS: Skills building interventions can produce ongoing sexual risk reduction in women in community drug treatment.
